A METHOD FOR ARRANGING ROLLING-FRICTION EXTENDING AND
RETRACTION BASED ROLLING STROKE SECTION OF A ROCKER ARM IN
PARALLEL, AND AN EXCAVATOR OR LOADER COMPRISING A ROCKER ARM
HAVING ROLLING STROKE SECTIONS IN PARALLEL
Technical field
The present invention relates to the field of excavators or loaders, and in
particular, to a
method for arranging rolling-friction extending and retraction based rolling
stroke sections of a
rocker arm in parallel, and an excavator or loader comprising a rocker arm
having rolling stroke
sections arranged in parallel.
Background
The rocker arms of commonly used equipment such as heading machines or coal
mining
machines or loading machines, for example, the rocker arms of reciprocating
impact heading
machines or the rocker arms of reciprocating impact coal mining machines or
the rolling harrow
support rocker arms of rolling-harrow loading machines, all extend and retract
relative to the
machine bodies by means of sliding friction, resulting in high sliding
friction resistance and
strong twisting force. In order to improve work efficiency and applicability,
the work heads of
the heading machine, the coal mining machine, the loading machine and the like
are designed to
have large volume and great weight. The work heads having large volume and
great height
produce great twisting gravity and serious reciprocating wear onto the
telescopic sliding guide
rail; moreover, in operation, crawling jitters are easy to occur, and in
serious cases, bonding burn
may appear in the sliding friction surface. The most critical thing is that
the adjustment to the
movement fails because it is difficult to form a uniform lubricating oil film
on the friction
surface thereof to generate heat by friction owing to the particularity of
working environment. In
order to avoid extending/retracting and sliding friction faults of the rocker
arms, many
manufacturers do not use telescopic rocker arms. However, service efficiency
and adaptability
are seriously reduced by forbidding the rocker arm to extend or retract
relative to the machine
body. In some cases, the slide rail is shortened in order to reduce sliding
frictional resistance, but
this would result in problems such as short rocker arm extending/retracting
distance, small
CA 02892409 2016-12-01
excavation or loading range, bad adaptability, and low operating efficiency,
etc. Furthermore, the
service efficiency and adaptability will be more seriously reduced if the
rocker arm is forbidden
to extend or retract relative to the machine body. In order to solve the above
problems, rolling
friction is used in the present invention to reduce wear and frictional
resistance, and more
especially, the rolling stroke sections of the rollers are arranged in
parallel. Therefore, the present
invention provides a method for arranging rolling-friction extending and
retraction based rolling
stroke sections of a rocker arm in parallel, and an excavator or loader
comprising a rocker arm
having rolling stroke sections arranged in parallel.

1. For the rocker arm of an excavator or loader having rolling stroke sections
arranged in
parallel, the front roller raceway and the rear roller raceway are arranged in
parallel; the front
roller rolls within the front roller raceway; the rear roller rolls within the
rear roller raceway; and
the front roller coordinates with the rear roller to support the rocker arm to
extend and retract by
means of rolling friction, to improve moving efficiency and flexibility of the
rocker arm in
adapting to excavating and/or loading various materials, and expand the
excavating and/or
loading range, thereby enabling the rocker arm to flexibly excavate and/or
load materials, etc.
2. The fixed wheel raceway and the traveling wheel raceway are arranged in
parallel; and
the fixed wheel overlaps some or all of the rolling stroke sections of the
traveling wheel, to
shorten the length between the fixed wheel raceway and the traveling wheel
raceway arranged
one behind the other, reduce the length of the rocker arm under equal
extending and retracting
9
CA 02892409 2016-12-01
distances, decrease the total height of the rocker arm, and shorten a force
arm that damages the
machine body through twisting, thereby reducing the use of raw materials, and
making the whole
machine more reasonable and compact in design and more safe, reliable and
flexible in
operation.
3. The slide opening roller rolls within a slide opening roller groove; the
slide opening roller
is fixed to the back of the rolling harrow telescopic arm; the fixed wheel
groove and the slide
opening roller groove are arranged in parallel; when the rolling harrow
telescopic arm is lifted up
by bulk materials, the fixed wheel groove hoists the fixed wheel to pull up
the rolling harrow
telescopic support arm; the slide opening roller and the fixed wheel support
and pull the rolling
harrow telescopic arm to extend/retract and ascend/descend.
4. The outer surface of the front roller is provided with a concave surface or
a convex
surface; if the outer surface of the front roller is provided with a concave
surface, the front roller
raceway is correspondingly provided with a convex surface engaged to the
concave surface of
the front roller to conduct rolling guide for the telescopic arm; if the outer
surface of the front
roller is provided with a convex surface, the front roller raceway is
correspondingly provided
with a concave surface engaged to the convex surface of the front roller to
conduct rolling guide
for the telescopic arm; the outer surface of the rear roller is provided with
a concave surface or a
convex surface; if the outer surface of the rear roller is provided with a
convex surface, the rear
roller raceway is correspondingly provided with a convex surface engaged to
the concave surface
of the rear roller to conduct rolling guide for the telescopic arm; if the
outer surface of the rear
roller is provided with a convex surface, the rear roller raceway is

limiting the rolling directions of the rollers, and controlling the
extending/retracting direction of
the telescopic arm.
5. The rocker arm is hingedly connected with a machine body via a rotary
limiting hinge
shaft or is connected with the machine body via a rotary structure; a rotation-
stopping limiting
structure is disposed at the hinge joint and a rotary joint of the rocker arm
and the machine body;
the rotary limiting platform rotates about the rotary structure or rotates
about the limiting hinge
shaft; when the rotary limiting platform rotates to an angle where the
telescopic support arm and
CA 02892409 2016-12-01
the work head are about to be in collision with a shovel plate, the machine
body rotation stopping
platform is pressed against the rotary limiting platform, so that the machine
body rotation
stopping platform stops the rotary limiting platform from continuing rotating;
the rocker arm is
limited to continue descending by limiting the rotation angle thereof, a
reasonable safety gap is
maintained between each of the rocker arm and the work head and the shovel
plate.
6. When the rocker arm extends out of a position to separate the work head
from the upper
part of the shovel plate, the rear-end raceway of the front roller raceway
rotates about the front
roller to enable the work head to be lower than the shovel plate for
excavation and/or loading.
7. The shovel plate frame is hingedly connected with the machine body frame or
the shovel
plate frame is connected with the machine body frame via a rotary structure;
one end of a shovel
plate controller is disposed on the machine body frame, and the other end is
disposed on the
shovel plate frame; the shovel plate controller drives the shovel plate to
ascend/descend in the
way of unidirectional rotation or multidirectional rotation, thereby further
improving the
applicability of the excavator or loader to excavate and/or load materials at
differing heights.
8. The shovel plate controller drives the shovel plate connected with the
shovel plate frame
to move up and down and/or move from side to side; the shovel plate frame
drives the rocker
arm to move up and down and/or move from side to side synchronously with the
shovel plate,
thereby preventing the shovel plate from being locked or in collision with the
rocker arm and the
work head when the movements of the shovel plate or the rocker arm and the
work head are
controlled respectively.
9. The discharge stopping device avoids the fault that the rolling harrow
throws the
materials to the machine body and the console and the like when harrowing the
materials
quickly.
10. One end of the shovel plate controller is hingedly connected to the shovel
plate
controller support or is connected with the shovel plate controller support
via the rotary structure,
and the other end is connected with the shovel plate frame; the joint of the

force arm at the joint
of the shovel plate frame and the machine body frame is greater than a
distance, in the event that
the shovel plate controller is disposed on the lower part of the machine body,
from the shovel
i
CA 02892409 2016-12-01
plate controller support to the force arm at the joint of the shovel plate
frame and the machine
body frame, so that the force arm that pulls the shovel plate to ascend and
descend is lengthened;
the shovel plate controller drives the shovel plate frame which drives the
shovel plate to
ascent/descend, thereby reducing power consumption and the number of the
shovel plate
controllers.
11. The anti-swing roller groove and the machine body are separately or
fixedly connected;
the anti-swing roller on the telescopic arm is engaged to the anti-swing
roller groove to roll
therein; the anti-swing roller performs linear reciprocating rolling in the
anti-swing roller groove
to support the rolling-friction extending and retraction of the telescopic
arm; the telescopic arm is
limited to swing from side to side by the anti-swing roller, so that the
telescopic arm ascends and
descends more stably.
12. The ascending/descending roller groove is engaged to the anti-swing roller
groove; the
ascending/descending roller rolls within the ascending/descending roller
groove; the anti-swing
roller rolls within the anti-swing roller groove; the rocker arm is hingedly
connected with the
machine body or is connected with the machine body via the rotary structure;
the telescopic arm
is limited to swing non-directionally from side to side by the anti-swing
roller and the telescopic
support arm is driven to ascend/descend by the ascending/descending roller, to
reduce a height
between the anti-swing roller groove and the ascending/descending roller
groove arranged one
below the other, as well as the total height of the rocker arm; the anti-swing
roller also drives the
rocker arm to ascend/descend; the ascending/descending roller groove and/or
the anti-swing
roller groove guides the rocker arm; and the ascending/descending roller
coordinates with the
anti-swing roller, thereby enhancing the control over the rolling and
extending/retraction of the
rocker arm.
13. The rotation-stopping limiting structure enables the rocker arm to form an
tilt angle
relative to the ground; the tilt angle enables the work head not to be in
collision with the shovel
plate; owing to the tilt angle, the rocker arm enables the work head to be
lower than the shovel
plate when extending out of the upper part of the shovel plate and to
excavate, mill, load or crush
the materials in the front of the shovel plate.
14. A shovel plate frame limiting gantry is disposed on the shovel plate frame
at the lower
part of the rocker arm; the shovel platform frame limiting gantry lifts up the
telescopic support
12
CA 02892409 2016-12-01
arm when the rocker and the work head descend to be about to collide with the
shovel plate,
thereby preventing the rocker arm and the work head from descending to be in
collision with the
shovel.
15. The shovel plate frame limiting gantry is provided with a buffer, etc.;
the buffer absorbs
the impact caused by the rocker arm during descending, thereby decreasing the
impact damage
caused by the descending of the rocker arm to the shovel plate frame limiting
gantry, etc.,
thereby reducing impact noise and improving work environment.
16. The length from the tip of each harrow tooth to the center line of the
tooth cylinder is
greater than the radius of the tooth cylinder, so that the harrow teeth are
easier to harrow and
shift materials.
17. The harrow teeth are like shovel heads, etc., thereby bringing benefit to
harrowing the
materials of different grain sizes into a conveying device, and improving the
capability of the
rolling harrow for harrowing and shifting scattered materials.
18. One end of a telescopic arm controller is connected with the rotary inner
disk under
rotation or the rotary outer disk under rotation, and the other end is
connected with the telescopic
arm; and the rocker arm rotates along with the rotary disk, thereby expanding
the excavating
and/or loading range, and increasing the material excavating, harrowing and
loading efficiency.
19. The telescopic section is hingedly connected with the support work head
section; the
hinge shaft is disposed perpendicularly to the ground; one end of the
extending and retraction
controller is connected with the machine body via a rotary structure or is
connected with the
telescopic support arm, and the other end is connected with the telescopic
section; one end of the
side-to-side movement controller is connected with the machine body via a
rotary structure or is
connected with the telescopic support arm or is connected with the telescopic
section, and the
other end is connected with the support work head section; the side-to-side
movement controller
drives the support work head section to move left and right, and the side-to-
side movement
controller drives the support work head section to move from side to side.
20. An electrical machine or motor is disposed in the tooth cylinder, so that
the roller
harrow has a simple and compact structure, thereby bringing benefit to
protecting the electrical
machine or motor with the tooth cylinder.
13
