VIBRO-HAMMER HAVING SIDE GRIP
[Technical Field]
[1] The present disclosure relates to a vibro-hammer connected to heavy
construction equipment, and more particularly, a vibro-hammer having a side
grip in
which vibrations are prevented from being transmitted to a connected heavy
equipment
machine to avoid a problem such as a change in a perforation position, the
vibro-
hammer is firmly connected to a perforated pile to transmit vibrations
generated in a
gear box to the perforated pile through the side grip and improve workability,
arms are
gear-coupled to each other to prevent the arms and the side grip from being
released
from each other due to frequent vibrations, a pair of arms and the side grip
can come
into close contact with the perforated file or separated from the performed
pile by a
single cylinder, the side grip can be easily replaced according a shape of the
perforated
pile, and applicability and workability is improved.
[Background Art]
[2] In general, in order to build all structures such as a building or
a bridge on the
ground, a foundation work must be performed to embed a concrete pile, a steel
pipe
pile, and an I-beam so that the ground can withstand the weight of the
structure.
[3] In the case of the pile construction, the pipe construction is very
important in
constructing the structure and the building, and in particular, in the case of
soft ground,
the foundation work in which a pile is drive and fixed in a bedrock in a
basement layer
below the ground surface should be carried out, and in the foundation work, an
operation of driving a pile into the ground is called a driving operation.
[4] Recently, in the driving operation, a method is mainly used, which
vibrates a
CA 3103008 2020-12-17
2
chuck in a driving direction, that is, in a vertical direction with respect to
the pile, using
a drive gear and an eccentric weight operated by driving a motor in a state
where the
pile is fixed through the vibro-hammer. Accordingly, a friction between the
pile and
the ground is reduced through the vibrations of the pile, and thus, a smooth
driving
operation is achieved.
[5] Meanwhile, since vibrations generated from a gear device including
the motor,
the drive gear and the eccentric weight are transmitted not only to the pile
but also to
the connected heavy equipment machine for construction, there is a concern
that the
machine is overwhelmed and may cause a breakdown.
[6] In addition, when vibrations are transmitted to a heavy equipment
machine,
there is a concern that a position is deviated from an initial position at
which the driving
operation is performed, and in this case, the position of the file is also
changed together.
Accordingly, there is a fatal disadvantage that the file cannot be stably
driven into the
ground and the foundation work is poor.

is divided into a sheet pile PI, an I-type file P2, and circular piles P3 and
P3' according
to the shapes thereof, and when explaining by applying different perforated
piles PI,
P2, and P3 as necessary, it should be stated that the description is given
with reference
numerals.
[57] The present disclosure relates to a vibro-hammer connected to heavy
construction equipment, and more particularly, a vibro-hammer having a side
grip in
which vibrations are prevented from being transmitted to a connected heavy
equipment
machine to avoid a problem such as a change in a perforation position and the
vibro-
hammer is firmly connected to a perforated pile to transmit vibrations
generated in a
gear box to the perforated pile through the side grip and improve workability,
and the
vibro-hammer 1 includes a mount portion 1000, a side clamp portion 2000, a
housing
bracket 3000, and a bottom clamp 4000.
[58] The mount portion 1000 is connected to a boom bracket or quick coupler
installed at a distal end of a boom of a construction heavy equipment machine
such as
an excavator and shovel.
[59] The mount portion 1000 has a plurality of holes which are formed on an
upper
CA 3103008 2020-12-17
10
surface to be coupled to the heavy equipment machine, and a lower surface of
the
mount portion 1000 is coupling-fixed in close contact with an upper surface of
the
housing bracket 3000 in a vertical direction.
[60] The side clamp portion 2000 generates vibrations through a provided
gear box
module 2110 provided to transmit the vibrations to a connected arm 2300 and a
side
grip 2400, and plays a role of easily griping and vibrating the perforated
pile so as to
perform perforation work. This side clamp portion 2000 includes a gear box
2100, a
cylinder 2200, the arm 2300 and the side grip 2400.
[61] The gear box 2100 includes the gear box module 2110 therein and has a
box
frame 2101 in the shape of a hexahedron with opened front surface and rear
surface,
and inside the box frame 2101, a plurality of horizontal frames 2102 divided
into regions
along an inner height of the box frame 2101 are provided.
[62] First, a cylinder coupling shaft 23130 coupled to an upper arm 2300a
descried
later and a pair of rotating shafts 2120 are provided inside the uppermost
horizontal
frame, and the pair of gear box modules 2110 is provided at a center of the
inside of
the box frame 2101 having the horizontal frame 2102 as upper and lower
surfaces,
and thus, generates vibrations.
[63] A hydraulic motor 2111 is provided on a rear surface of the gear box
module
2110 to generate vibrations, and as illustrated in FIG. 2A, a gear 2110b and
an
eccentric weight 2110c are coupled to shaft 2110a inside the gear box module
2110 to
generate vibrations.
[64] The vibrations generated by the gear box module 2110 is connected to
the box
frame 2101 and the horizontal frame 2102, and is transmitted to the arm 2300
and the
side grip 2400 connected to the gear box 2100. Accordingly, the perforated
pile
gripped by the side grip 2400 is vibrated.
CA 3103008 2020-12-17
[65] A horizontal frame 2102 having a vertical distance corresponding to
the heights
of the rotating shaft 2120 and the cylinder coupling shaft 2130 is also
provided on the
lower side where the gear box module 2110 is provided. That is, the inside of
the box
frame 2101 is divided into three zones, the gear box module 2110 generating
vibrations
is provided at the center thereof, and on upper side and lower side based on
the gear
box module 2110, the rotating shaft 2120 and the cylinder coupling shaft 2130
coupled
to the cylinder 2200 and the arm 2300 are coupled to the horizontal frame 2102
located
in the vertical direction, and thus, the cylinder 2200 and the arm 2300 are
not deviated
from installation positions thereof, and are connected to the box frame 2101
to receive
vibrations.
[66] Moreover, an engagement portion 2140 is provided on a front surface on
which
the rotating shaft 2102 and the cylinder coupling shaft 2130 so as to prevent
the pair
of arms 2300 from excessively rotating inward. That is, an engagement groove
2141
is formed on the rear surface side of the engagement portion 2140 to be
recessed in
the front surface direction from the rear surface, and in order to prevent the
gear-
coupled first and second arms 2310 and 2320 from being separated from each
other
due to excessive rotation of a gear arm 2330 described later, the first and
second arms
are gear-coupled inside the engagement groove 2141.
[67] Moreover, a front frame 2103 is provided on the front surface side of
the gear
box 2100, the arm 2300 is introduced into an inlet/outlet hole 2104 formed to
horizontally penetrate the front frame 2103 so as to move the inside of the
inlet/outlet
hole 2104, and thus, the pair of arms 2300 can be prevented from excessively
rotating.
[68] The rotating shaft 2120 vertically penetrates rotating shaft
introduction holes
2302 respectively formed in the first and second arms 2310 and 2320, the first
and
second arms 2310 and 2320 can rotate about the coupled rotating shaft 2120,
the
CA 3103008 2020-12-17
12
cylinder coupling shaft 2130 penetrates the shaft coupling hole 2210 formed on
one
end of the cylinder 2200 and is coupled thereto, the other end of the cylinder
2200 is
coupled to the first arm 2310 formed in the cylinder coupling hole 2301 of the
arm 2300
to drive the cylinder 2200, and thus, the first arm 2310 rotates about the
rotating shaft
2120.
[69] The cylinder 2200 is driven so that the connected arm 2300, that is,
the first
arm 2310 rotates about the coupled rotating shaft 2120. When the first arm
2310 is
rotated to one side by the driving of the cylinder 2200, the pair of arms 2300
is close
to each other, comes into close contact with the outer surface of the
perforated pile to
grip the perforated pile, or when the first arm 2310 rotates to the other
side, the pair of
arms 2300 is away from each other to be separated from the outer surface of
the
perforated pile, and thus, is detached from the perforated pile.
[70] The cylinder 2200 may be driven by a heavy equipment machine connected
to
the vibro-hammer 1 or a separate operation module (not illustrated in the
drawings)
provided outside. As illustrated in FIG. 3A and Fig. 3B, the cylinder 2200 is
provided
on a side opposite to the positions of the upper arm 2300a and the lower arm
2300b.
Therefore, the side clamp portion 2000 is prevented from being bent one side
due to
that the cylinder 2200 is driven to one side, and the cylinders 2200 are
provided to
intersect each other. Accordingly, the side clamp portion 2000 uniformly grips
the
perforated pile and grips the perforated pile with a good balance, and thus,
the side
clamp portion 2000 also has a good balance and is prevented from being pulled
to one
side.
[71] The arm 2300 connected to the cylinder 2200 and the rotating shaft
2120 of
the gear box 2100 is divided into the upper arm 2300a located above the gear
box
2110 and the lower arm 2300b located below the gear box 2110, and thus, the
pair of
CA 3103008 2020-12-17
13
arms 2300 includes the first arm 2310 and the second arm 2320.
[72] First, in each of the upper arm 2300a and the lower arm 2300bb, the
first arm
2310 and the second arm 2320, and the cylinder 2200 are provided on sides
opposite
to each other in the vertical direction, and thus, when the cylinder 2200 is
driven, the
first arm 2310 and the second arm 2320, and the cylinder 2200 intersect each
other in
a plan view.
[73] Each of the upper arm 2300a and the lower arm 2300b is coupled to the
side
grip 2400, and not simply grip only one side of the perforated pile but grips
upper and
lower portions on the same vertical line to be in stable-close contact with
the perforated
pile and fixed to the perforated pile.
[74] The first arm 2310 and the second arm 2320 have the same shape as each
other, and the first arm 2310 has a cylinder coupling hole 2301 for coupling
the cylinder
2200 on an end portion extending to the cylinder 2200 side.
[75] In each of the first arm 2310 and the second arm 2320, the rotating
shaft
introduction hole 2302 is formed so that the rotating shaft 2120 vertically
penetrates
and is coupled to the arm, and gear arms 2330 are formed at a position close
to the
rotating shaft introduction hole 2302 so that the first arm 2310 and the
second arm
2320 are gear-coupled to each other.
[76] The gear arm 2330 is provided on a side on which the rotating shaft
introduction hole 2302 of each of the first arm 2310 and the second arm 2320
is
provided, and teeth of the gear arm 2330 are formed to protrude the side of
the other
facing arm 2300. Moreover, in order to easily perform replacement later, the
gear is
not directly formed on the arm 2300, and the gear arm 2330 formed along a side
surface according to a degree of the rotation of the arm 2300 is coupled to
the gear
coupling hole 2303 so that the arm 2300 and the gear arm 2330 can be coupled.
CA 3103008 2020-12-17
14
[77] That is, the upper surface of the gear arm 2330 is provided with a
protrusion
protruding upward according to the position of the gear coupling hole 2303
which can
penetrate the inside of the gear coupling hole 2303, the protrusion is
introduced into
the gear coupling hole 2303, and thus, the gear arm 2330 and the arm 2300 can
be
coupled to each other. In addition, when a gear portion of the gear arm 2330
is worn
due to frequent use, or the like, only the gear arm 2330 can be removed from
the arm
2300 and replaced.
[78] The first arm 2310 and the second arm 2320 protrude to the front
surface side
of the gear box 2100 about the position where the rotating shaft coupling hole
2210 is
formed, and the side surfaces of the perforated piles are easily provided
inside, and
protrude in a lateral direction so that the perforated pile is easily provided
therein.
[79] Moreover, a first coupling bracket 2340 which can be coupled to the
side grip
2400 is provided on a protruding end portion of each of the first arm 2310 and
the
second arm 2320. The first coupling bracket 2340 comes into close contact with
the
.. second coupling bracket 2420 of the side grip 2400 described later, and a
separate
coupling member such as a bolt penetrates the first coupling bracket 2340 and
the
second coupling bracket 2420, and thus, the first and second coupling brackets
2340
and 2420 are fixed to each other.
[80] Accordingly, the first and second arms 2310 and 2320 are coupled to
the
rotating shaft 2120 in the gear box 2100, and vibrations generated in the gear
box
module 2110 can be transmitted to the side grip 2400 side through the arm
2300.
[81] One end of the side grip 2400 is connected to the arm 2300 so that the
side
grip 2400 receives the vibrations transmitted from the gear box 2100 side, the
other
end of the side grip 2400 comes into close contact with the perforated pile to
be fixed
thereto, the vibrations transmitted from the gear box 2100 side is transmitted
to the
CA 3103008 2020-12-17
15
close contacted perforated pile, and thus, the perforated pile can perform
perforation
work by the vibrations.
[82] The side grip 2400 extends similarly to the arm 2300 of which one end
extends,
and an end portion side of the side grip 2400 includes a side grip frame 2410
curved
.. inward so that the side grip 2400 comes into close contact with the
perforated pile
provided inside.
[83] One end of the side grip frame 2410 includes the second coupling
bracket
2420 to be coupled to the above-described first coupling bracket 2340.
[84] In this case, in the second coupling bracket 2420, the second coupling
bracket
.. 2420 has a height corresponding to the pair of first coupling brackets 2340
located at
the same vertical line so that the upper arm 2300a and the lower arm 2300b are
coupled by one side grip 2400 and the pair of first coupling bracket 2340
respectively
provided in the upper arm 2300a and the lower arm 2300b and located on the
same
vertical line are coupled to the single second coupling bracket 2420 (refer to
FIGS. 4A
.. and 6A).
[85] The second coupling bracket 2420 allows the upper arm 2300a and the
lower
arm 2300b to come into close contact with the perforated pile in the same way
through
the second coupling bracket 2420 even if the upper arm 2300a and the lower arm
2300b are not driven equally due to a slight difference.
[86] The other end of the side grip frame 2410 includes a close-contact
portion
2430 which comes into close contact with the outer surface of the perforated
pile.
[87] In the close-contact portion 2430, a close-contact surface in close
contact with
the perforated pile includes a slight protrusion having a pyramid shape to
increase a
friction force with the outer surface of the perforated pile and secure stable
fixing and
.. coupling. Moreover, a shape of the protrusion may be configured in an
embodiment
CA 3103008 2020-12-17
16
illustrated in FIGS. 4 and 5 or another embodiment illustrated in FIG. 6
according to
the shape of the perforated pile.
[88] A user of the side grip 2400 having the above-described embodiments
separate the first and second coupling brackets 2340 and 2420 coupled
according to
the shape of the perforated pile from each other, and thereafter, couples the
second
coupling bracket 2420 of the side grip 2400 to be used to the first coupling
bracket
2340. Accordingly, the user can use the side grip 2400 matching the perforated
piles
having various shapes.
[89] First, when the perforation work is performed using the sheet pile P1,
as
illustrated in FIG. 4a, the close-contact portion 2430 having a columnar shape
in which
the close-contact portion 2430 is connected to the other end of the side grip
frame
2410 is used, and a plurality of protrusion are formed on the close-contact
surface of
the close-contact portion 2430.
[90] In this case, together with the second coupling bracket 2420, a
vertical bracket
2440 which connects the side grip 2400 coupled to the upper arm 2300a and the
lower
arm 2300b to the side grip 2400 located on the same vertical line may be
provided.
[91] The vertical bracket 2400 prevents the side grip 2400 from being
inclined
downward due to frequent vibrations and load, and the side grips 2400 located
on the
upper side and lower side at equal intervals can come into close contact with
the
perforated pile similarly.
[92] In this case, the vertical bracket 2440 may be contracted or expanded
due to
thermal deformation or the like. When the vertical bracket 2440 is warped,
since the
position of the side grip 2400 connected to the upper and lower ends is
changed,
preferably, a plurality of perforation holes are provided in the vertical
bracket 2440.
[93] Accordingly, as illustrated in FIG. 4B, in the sheet pile P1 having
the above-
CA 3103008 2020-12-17
17
described configuration, the close-contact portion 2430 comes into close
contact with
the inside of the sheet pile P1, both end portions of the sheet pile P1
protruding to one
side are provided between the arm 2300 extending outward and the side grip
2400,
and thus, the close fixing of the perforated pile can be realized.
[94] Thereafter, when the cylinder 2200 is driven and contracted, the first
arm 2310
coupled to the cylinder 2200 rotates about the rotating shaft 2120, the gear
arm 2330
coupled to the first arm 2310 and the gear arm 2330 of the gear-coupled second
arm
2320 rotate in directions opposite to each other, and thus, the second arm
2320 and
the first arm are away from each other, the side grips 2400 which are
connected to the
first and second arms 2310 and 2320 and located at the same horizontal line
are away
from each other, the close-contact portion 2430 and the perforated pile are
away from
each other, and thus, the perforated pile and the side grip 2400 can be
separated from
each other.
[95] Meanwhile, when the I beam (P2) other than the sheet pile P1 and the
side
grips 2400 are coupled to each other, an auxiliary close-contact portion 2450
which
locks the end portions protruding to the side surface of the I beam P2 to the
side grip
2400 so as to further fix the I beam P2 may be formed.
[96] The auxiliary close-contact portion 2450 is provided on a front
surface side of
the side grip 2400 to protrude to the close-contact portion 2430 side, and has
a close-
contact groove 2451 which is recessed in a direction opposite to the close-
contact
surface of the close-contact portion 2430.
[97] When the side grip 2400 comes into close contact with the I beam P2,
the end
portion protruding inside the close-contact groove 2451 can be introduced, and
thus,
as illustrated in FIG. 5A, the end portion of the I beam P2 can be locked to
the inner
surface of the close-contact groove 2451 in the auxiliary close-contact
portion 2450 to
CA 3103008 2020-12-17
18
be fixed thereto.
[98] Accordingly, the auxiliary close-contact portion 2450 can fix the side
grip 2400
together with the close-contact portion 2430, and even when the I beam P2 is
deviated
from the side grip 2400 due to excessive vibrations, the I beam P2 is locked
to the
inside of the close-contact groove 2451, and thus, the I-beam P2 does not move
or
deviate over a predetermined radius.
[99] Meanwhile, When the outer surface is curved such as the circular pile
P3, it is
difficult to fix the circular pile P3 to the side grip 2400 in a close contact
state by only
the pair of close-contact portions 2430. Particularly, when strong vibrations
are
applied, the side grip 2400 slides along the curved outer surface of the
circular pile P3,
and thus, there is a concern that the circular pile P3 is deviated from the
inside of the
side grip 2400.
[100] Accordingly, in another embodiment of the side grip 2400, the pair of
close-
contact portions 2430 is provided, and the side grip 2400 can be rotated along
the
.. curvature of the outer surface of the circular pile P3, which will be
described with
reference to FIGS. 6 to 6C.
[101] In another embodiment of FIG. 6, when the side grip 2400 comes into
contact
with the circular pile P3, as illustrated in FIG. 6b, the close-contact
portion 2430 has a
contact point in a tangential form on the outer surface of the circular pile
P3, and the
close-contact portion 2430 can come into close contact with the outer surface
about
the contact point and be fixed thereto.
[102] In this case, in one side grip 2400, that is, in the side grip 2400
coupled to the
upper arm 2300a and the lower arm 2300b, the pair of close-contact portion
2430
located on the same horizontal line is separated from each other and is
provided inside
the side grip 2400, and the side grip 2400 comes into close contact with the
circular
CA 3103008 2020-12-17
19
pile P3 to surround upper portion and lower portion of one side and the other
side of
the circular pile P3 and is fixed thereto.
[103] Meanwhile, the pair of close-contact portions 2430 may be disposed to
face
the center of the inside of the side grip 2400. However, when the close-
contact
portion 2430 is fixed thereto, there is a concern that the close-contact
portion cannot
come into close contact with the circular pile P3 having various outer
diameters.
[104] Accordingly, in the present disclosure, the close-contact portion 2430
can
rotate so that the close-contact portion 2430 comes into close contact with
the outer
surface of the circular pile P3 having various diameters in a tangential form.
[105] A protruding rotation portion 2431 is provided on a surface opposite to
the
surface on which the close-contact surface is formed, and the rotation portion
2431
has a hole penetrating vertically.
[106] Moreover, the other end of the side grip 2400, that is, an end portion
on which
the close-contact portion 2430 is provided has a rotation portion moving
groove 2411
in which an end surface corresponding to a height of the rotation portion 2431
is
recessed.
[107] The rotation portion moving groove 2411 is recessed in a state where a
front
surface and a rear surface are open on the other end of the side grip frame
2410, the
rotation portion 2431 is introduced into the rotation portion moving groove
2411, and
thus, the rotation portion 2431 can rotate along the rotation portion moving
groove 2411.
[108] In addition, a hole vertically penetrating the upper and lower surfaces
of the
side grip frame 2410 is formed on the upper and lower surfaces of the side
grip frame
2410 in which the rotation portion moving groove 2411 is formed, a hole
vertically
penetrating the rotation portion 2431 is formed in the rotation portion 2431
introduced
into the rotation portion moving groove 2411, and the hole communicating with
the
CA 3103008 2020-12-17
20
inside of the rotation portion moving groove 2411 communicates with the inside
of the
hole formed in the rotation portion 2431 and can be coupled thereto.
[109] Thereafter, the close-contact portion rotating shaft 2120 is provided,
which
vertically passes through the hole formed in the side grip frame 2410 and the
hole
formed in the rotation portion 2431 and fixes the rotation portion 2431 to the
end portion
of the side grip frame 2410.
[110] Therefore, as illustrated in FIG. 6C, the rotation portion 2431 can
automatically
rotate (direction of arrow) about the close-contact portion rotating shaft
2120, the close-
contact portion 2430 also rotates together according to the rotation of the
rotation
portion 2431 and comes into close contact with the outer peripheral surface of
the
circular pile P3' provided inside the close-contact portion 2430 in a
tangential form, and
thus, the side grip 2400 can come into close contact with the circular pile
P3' and can
be fixed thereto.
[111] In this case, a ball bearing (not illustrated) is provided on an outer
surface of
the close-contact portion rotating shaft 2120, that is, outer surfaces of an
upper end
and a lower end penetrating the side grip 2400 so that the close-contact
portion rotating
shaft 2120 can easily rotate the rotation portion 2431. Accordingly, the user
can rotate
the arm 2300 without separately rotating the rotation portion 2431, and thus,
the close-
contact portion 2430 can come into close contact with the outer surfaces of
the circular
piles P3 and P3' and can automatically rotate in a tangential form to come
into close
contact with the circular piles P3 and P3.
[112] In another embodiment of the side grip 2400, not only the sheet pile P1
or the
I beam P2 but also the circular piles P3 and P3 can be easily fixed to the
side grip
2400. Moreover, the side grip 2400 comes into close contact with the circular
pile P3
and automatically rotates according to the outer peripheral surface of the
circular pile
CA 3103008 2020-12-17
21
P3. In addition, the close-contact portion 2430 comes into close contact
with the outer
peripheral surface of the circular pile P3 in a tangential form in order to
increase a
friction area, and it is possible to increase a close contact force and a
fixing force.
[113] The housing bracket 3000 is provided outside the above-described side
clamp
portion 2000, the gear box 2100 is coupling-fixed to an internal space of the
housing
bracket 3000, and an upper surface of the housing bracket 3000 is coupled to
the lower
surface of the mount portion 1000 so that the housing bracket 3000 is
connected to
the mount portion 1000 and the heavy equipment machine.
[114] The housing bracket 3000 has a hexahedral shape with an open bottom
surface and front and rear surfaces, and the gear box 2100 is provided inside
the
housing bracket 3000. In this case, the rear surface of the housing bracket
3000 is
open so that the housing bracket 3000 does not interference with the cylinder
2200
when the cylinder 2200 described later moves horizontally, and a separate
bracket for
protecting the rear surface of the gear box module 2110 is further provided at
a center
side.
[115] Accordingly, the arm 2300 and the side grip 2400 are provided on the
open
front surface of the housing bracket 3000, the bottom clamp 4000 is provided
on the
open bottom surface, the rear surface is partially open so that the end
portion of the
cylinder 2200 protrudes from or enters the open rear surface of the housing
bracket
3000 according to the operation of the cylinder 2200, and the rear surface
side of the
gear box module 2110 is closed to be protected from the outside.
[116] Particularly, when the perforation work is performed, in a case where
fine sand
or boulders move toward the gear box module 2110 side, malfunction of the gear
box
module 2110 is generated, and thus, it is necessary to protect the gear box
module
2110.
CA 3103008 2020-12-17
22
[117] In addition, when the vibrating side clamp portion 2000 is directly
connected to
the mount portion 1000, vibrations generated in the gear box module 2110 or
impact
generated due to the perforated pile coupled to the side grip 2400 colliding
with the
ground is transmitted to the heavy equipment machine side, the position of the
heavy
equipment machine is changed or malfunction of the machine is generated due to
the
frequent impact. Accordingly, in order to solve the problems, the housing
bracket
3000 is provided outside the side clamp portion 2000, the mount portion 1000
is
coupled to the housing bracket 3000, and thus, the impact or vibrations
transmitted to
the side clamp portion 2000 is reduced, and the impact or vibrations
transmitted to the
heavy equipment machine can be minimized.
[118] The housing bracket 3000 includes an upper housing bracket 3100 which is
directly coupled to the mount portion 1000, and a lower housing bracket 3200
which
has an upper surface on which a rotary joint 3130 is provided, is coupled to
the upper
housing bracket 3100, and has a hexahedron shape having open front surface,
rear
.. surface, and lower surface.
[119] First, the upper housing bracket 3100 has an upper surface having the
same
shape as the lower surface of the mount portion 1000, is coupled to the mount
portion
1000 through a separate bolt in a state where the upper surface of the upper
housing
bracket 3100 is in close contact with the lower surface of the mount portion
1000, and
is coupling-fixed to the mount portion 1000 in a close contact state.
[120] The housing bracket 3100 includes a first upper housing bracket 3110
connected to the mount portion 1000 and a second upper housing bracket 3120
connected to the lower housing bracket 3200.
[121] First, the first upper housing bracket 3110 has a shape corresponding to
the
lower surface of the mount portion 1000, edges of a front surface and a rear
surface
CA 3103008 2020-12-17
23
of the first upper housing bracket 3110 protrude downward, and the protruding
end
portion has a first coupling hole 3111 formed in the horizontal direction.
[122] The second upper housing bracket 3120 has a circular lower surface,
edges
of a front surface and a rear surface of an upper surface of the second upper
housing
bracket 3120 protrude upward, and the protruding end portion has a second
coupling
hole 3121 formed in the horizontal direction.
[123] Accordingly, the protruding upper surface and lower surface of the first
upper
housing bracket 3110 and the second upper housing bracket 3120 are combined
with
each other, a through bolt B penetrates the first coupling hole 3111 and the
second
coupling hole 3121, and thus, the first and second upper housing brackets 3110
and
3120 are coupled to each other.
[124] In this case, a rotary motor 3140 which can rotate the lower housing
bracket
3200, the side clamp portion 2000, and the bottom clamp 4000, a tilting
cylinder 2200,
and a hydraulic control valve 3160 are provided at a center vertically
separated from
.. the first and second upper housing brackets 3110 and 3120.
[125] The rotary joint 3130 which penetrates vertically and connects the upper
surface of the lower housing bracket 3200 to the lower surface of the second
upper
housing bracket 3120 is provided at the center of a lower surface of the
second upper
housing bracket 3120. Accordingly, the lower housing bracket 3200 can rotate
about
the rotary joint 3130 below the second upper housing bracket 3120, and the
second
upper housing bracket 3120 can maintain a fixed state through the coupled
first upper
housing bracket 3110.
[126] A slugging bearing 3170 is provided at a space between the second upper
housing bracket 3120 and the lower housing bracket 3200, and thus, the lower
housing
bracket 3200 can be easily rotated.
CA 3103008 2020-12-17
24
[127] Accordingly, respective components of the hosing bracket 3000 are
connected
to each other but not in close contact with each other. That is, the
components are
coupled to each other in a state separated from each other, and thus, it is
possible to
minimize the vibrations generated from the side clamp portion 2000 from being
transmitted to the mount portion 1000 and the heavy equipment machine.
[128] Moreover, the side clamp portion 2000 can be easily rotated according to
the
position of the perforated pile, the perforated pile can be gripped in a
closer contact
state, and thus, it is possible to improve the coupling force and the fixing
force.
[129] When the perforated pile is driven into the ground at a predetermined
depth or
more through the side clamp portion 2000, the bottom clamp 4000 applies
vibrations
to the upper end of the perforated pile to perform the perforation work. That
is, when
the perforated pile is driven into the ground through the perforation work,
the height of
the side grip 2400 decreases, and in this case, there is a concern that the
side grip
2400 is difficult to come into close contact with the outer peripheral surface
of the
perforated pile.
[130] Accordingly, the bottom clamp 4000 applies vibrations to the upper end
of the
perforated pile drive into the ground, and thus, the perforated pile can be
driven to a
desired depth.
[131] The bottom clamp 400 is inserted into the inside of the lower surface of
the
gear box module 2110 of the gear box 2100, and is coupling-fixed thereto.
[132] Meanwhile, when the housing bracket 3000 comes into close contact with
the
gear box 2100 to be coupled thereto, there is a concern that the vibrations
generated
from the side clamp portion 2000 are transmitted to the mount portion 1000 and
the
heavy equipment machine through the housing bracket 3000.
[133] Accordingly, an anti-vibration rubber 5000 may be further provided,
which
CA 3103008 2020-12-17
25
couples the gear box 2100 and the housing bracket 3000 to each other in a
state of
being separated from each other, and minimizes vibrations transmitted from the
gear
box 2100 to the housing bracket 3000 side.
[134] A plurality of anti-vibration rubbers 5000 are interposed between both
side
surfaces of the gear box 2101 of the gear box 2100 and the housing bracket
3000, the
vibrations generated from the gear box module 2110 are transmitted to the
housing
bracket 3000 through the anti-vibration rubbers 5000, and thus, it is possible
to
minimize the vibrations transmitted to the housing bracket 3000.
[135] The anti-vibration rubber 5000 has a cylindrical shape of which an outer
peripheral surface is curved to be recessed inward. Compared to a simple
cylindrical
rubber, in this anti-vibration rubber 500 having the cylindrical shape, a
width of the anti-
vibration rubber 5000 to which vibrations are transmitted is reduced, the
vibrations are
minimized, and thus, the vibrations transmitted through the anti-vibration
rubber 5000
can be reduced.
[136] In addition, anti-vibration rubber brackets 5001 are respectively
provided on
both side ends of the anti-vibration rubber 5000 and respectively fixed to the
inner
surface of the lower housing bracket 3200 and the outer surface of the box
frame 2101.
Accordingly, the gear box 2100 is coupled to the housing bracket 3000, the
inner
surface of the housing bracket 3000 and the outer surface of the gear box 2100
are
separated from each other, and thus, the housing bracket 3000 and the gear box
2100
are prevented from being coupled to each other in a state of being in close
contact with
each other, and vibrations are prevented from being directly transmitted.
[137] Meanwhile, the anti-vibration rubber 5000 has a number corresponding to
height and width of the side surface of the box frame 2101 as illustrated in
FIG. 2, and
in the present disclosure, four pairs of anti-vibration rubber 5000 are
disposed for each
CA 3103008 2020-12-17
26
side surface of the box frame 2101. However, the present disclosure is not
limited to
this.
[138] Hereinbefore, preferred embodiments are disclosed in the drawings and
specification. Here, characteristic terms are used, but these are only used
for the
purpose of describing the present disclosure, and are not used to limit
meaning or a
scope of the present disclosure described in claims. Therefore, those of
ordinary skill
in the art will understand that various modifications and equivalent other
embodiments
are possible therefrom. Therefore, a true technical scope of the present
disclosure
should be determined by a technical spirit of the appended claims.
