MULTI-ROPE COOPERATIVE CONTROL SYSTEM TESTBED OF ULTRADEEP MINE
HOIST
Technical Field
The present invention relates to multi-rope cooperative control system
testbeds for hoists, and
in particular, to a multi-rope cooperative control system testbed for an
ultradeep mine hoist.
Background
Currently, as China chooses deep resource exploitation as an important
development strategy,
large-scale ultradeep mine hoisting equipment becomes critical equipment for
implementing deep
resource exploitation. However, the research in the field of ultradeep mine
hoisting equipment is still
in the initial stage in China, and as a result the implementation of the
strategy of exploiting and
utilizing deep resources is constrained in China. Moreover, because actual
working conditions of
ultradeep mines are complex and mining environments are special, it is very
difficult to perform the
field test for hoisting equipment. Therefore, to test the working performance
of ultradeep mine
hoisting equipment and achieve a detection level for ultradeep mine hoisting
systems, there is an
urgent need for a testbed for ultradeep mine hoisting system that can simulate
actual conditions. The
testbed needs to simulate various working states in working environments of
ultradeep mines, so as
to achieve the objective of effectively detecting the working performance of
the hoisting equipment,
and ensure that a hoisting system can operate safely and reliably in
environments of complex
working conditions.
Summary
An objective of the present invention is to provide a multi-rope cooperative
control system
testbed for an ultradeep mine hoist, so as to implement simulation of the
movement condition of an
ultradeep mine hoist under an actual working condition, monitor tensile forces
applied to wire ropes,
pressures applied to headgear sheaves, and the horizontalness of a hoisting
conveyance, and ensure
that a hoisting system can operate safely and reliably in environments of
complex working
conditions.
The objective of the present invention is achieved as follows: The control
system testbed

back signals. The servo
hydraulic cylinders are fixed on the hinges, and upper ends of the servo
hydraulic cylinders are
connected to the headgear sheave brackets. The headgear sheaves are connected
to the headgear
sheave brackets. The headgear sheave brackets are fixed on the linear guide
rails. The hinges and the
linear guide rails are connected to the steel structural brackets. The servo
hydraulic cylinders drive
the headgear sheaves to move up and down by means of the headgear sheave
brackets. The tension
sensors are placed on the wire ropes to detect tensile forces of the wire
ropes. The pressure sensors
are placed on the headgear sheave brackets to detect pressures applied to the

computer and the lower computer transmit data through an Ethernet. A control
signal and a feedback
signal are transmitted to the lower computer or an execution mechanism via the
conditioning box.
Beneficial effects: In the testbed of the present invention, a cage is
perpendicularly hoisted by
using a mode of the drag of hydraulic motors that is easy to implement
control, thereby making the
operations simple, and helping to carry out maintenance. The testbed can
implement multiple
functions, and tension sensors are used to measure the tension in hoisting
wire ropes. Pressure
sensors are used to measure pressures applied to headgear sheaves. A spiral
instrument is used to

Detailed Description of Embodiments
The present invention is described below in detail with reference to specific
embodiments.
Embodiment 1: In FIG. 1 and FIG. 2, a control system testbed includes: four
hydraulic motors
1, corresponding four rollers 2, corresponding four wire ropes 3, a set of
steel structural brackets 4,
four hinges 5, four servo hydraulic cylinders 6, four linear guide rails 7,
four headgear sheaves 8,
four headgear sheave brackets 9, four pressure sensors 10, four tension
sensors 11, one spiral
instrument 12, one cage 13, four couplings 14, a motor base 15, and one oil
pump 16.
The hydraulic motors 1 are connected to the rollers 2 through the couplings
14. The rollers 2
are provided with the wire ropes 3. The wire ropes 3 are connected to the cage
13. The tension
sensors 11 are placed on the wire ropes 3 to detect tensile forces of the wire
ropes 3 and feed back
signals. The servo hydraulic cylinders 6 are fixed on the hinges 5, and upper
ends of the servo
hydraulic cylinders 6 are connected to the headgear sheave brackets 9. The
headgear sheaves 8 are
connected to the headgear sheave brackets 9. The headgear sheave brackets 9
are fixed on the linear
guide rails 7. The hinges 5 and the linear guide rails 7 are connected to the
steel structural brackets 4.
The servo hydraulic cylinders 6 drive the headgear sheaves 8 to move up and
down through the
headgear sheave brackets 9. The tension sensors 11 are placed on the wire
ropes 3 to detect the
3

CA 03008469 2018-06-14
tensile forces of the wire ropes 3. The pressure sensors 10 are placed on the
headgear sheave
brackets 9 to detect pressures applied to the headgear sheaves 8 and feed back
signals to the lower
computer 18. The spiral instrument 12 is fixed above the cage-13 to detect
whether the cage 13 is
horizontal and feed back signals to the lower computer 18. The cage 13 is
located in the steel
structural brackets 4, and the hydraulic motors 1 are mounted on the motor
base 15.
A four-rope drag mode is used for the cage 13, and is used to hoist relatively
heavy cargo, and
an arrangement form complies with an actual working condition.
The controller includes: a control cabinet 17, the lower computer 18, a
conditioning box 19,
and a mobile power module 20. The lower computer 18, the conditioning box 19,
and the mobile
power module 20 are mounted in the control cabinet 17. The oil pump 16 is
located on a side of the
control cabinet 17. An upper computer and the lower computer 18 transmit data
through an Ethernet.
A control signal and a feedback signal are transmitted to the lower computer
or an execution
mechanism via the conditioning box 19.
The tension sensors 11 are placed on the wire ropes 3 to detect tensile forces
of the wire ropes 3
and generate a tensile force signal. The pressure sensors 10 are placed on the
headgear sheave
brackets 9 to detect pressures applied to the headgear sheaves 8, and generate
a pressure signal. The
spiral instrument 12 is fixed above the cage 13 to detect whether the cage 13
is horizontal and
generate a horizontalness signal. The three groups of signal data, namely, the
tensile force signal, the
pressure signal, and the horizontalness signal, are transferred to a control
panel to perform
closed-loop data processing.
The four hydraulic motors 1 are controlled to rotate back and forth to
implement the vertical
movement of the cage 13. For the vertical movement of the cage 13, a guide
rail for the cage 13 may
be used to control a movement track, and the hoisting height of the cage 13
can be adjusted through
fine adjustment of the servo hydraulic cylinders.
In the multi-rope cooperative control system testbed for an ultradeep mine
hoist, through fine
adjustment of the four servo hydraulic cylinders 6 below the headgear sheaves
8, the horizontalness
of the cage 13 can be kept and tensile forces applied to the four wire ropes 3
can be kept the same.
In the multi-rope cooperative control system testbed for an ultradeep mine
hoist, the
4

CA 03008469 2018-06-14
conditioning box 19, the execution mechanism, the pressure sensors 10, the
tension sensors 11, and
the spiral instrument 12 are all powered by the mobile power module 20.
A specific working process of the multi-rope cooperative control system
testbed for an
ultradeep mine hoist is: When the test is started, the upper computer and the
lower computer 18
exchange data through an Ethernet. The conditioning box 19 is then used to
adjust the rotational
speeds of the hydraulic motors 1 to control the rollers 2 of the hoist to
rotate, so as to drive the wire
ropes 3 to move and control the vertical movement of the cage 13. The pressure
sensors 10, the
tension sensors 11, and the spiral instrument 12 feed back measurement data to
the lower computer
18 via the conditioning box 19. After data conversion, the conditioning box 19
is then used to
control the extension and compression of the servo hydraulic cylinders 6 to
form closed-loop
control.
