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 includes: four hydraulic motors, corresponding four rollers, corresponding four wire ropes, a set of steel structural brackets, four hinges, four servo hydraulic cylinders, four linear guide rails, four headgear sheaves, four headgear sheave brackets, four pressure sensors, four tension sensors, one spiral instrument, one cage, four couplings, a motor base, and one oil pump.
The hydraulic motors are connected to the rollers through the couplings. The rollers are provided with the wire ropes. The wire ropes are connected to the cage. The tension sensors are placed on the wire ropes to detect tensile forces of the wire ropes and feed 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 headgear sheaves and feed back signals to a lower computer. The spiral instrument is fixed above the cage to detect whether the cage is horizontal and feed back signals to the lower computer.
The cage is located in the steel structural brackets, and the hydraulic motors are mounted on the motor base.
A four-rope drag mode is used for the cage and is used to hoist relatively heavy cargo, and an arrangement form complies with an actual working condition.
The controller includes: a control cabinet, the lower computer, a conditioning box, and a mobile power module. The lower computer, the conditioning box, and the mobile power module are mounted in the control cabinet. The oil pump is located on a side of the control cabinet. An upper 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 monitor the horizontalness of the cage. The hydraulic motors are controlled to rotate back and forth
2 to adjust the vertical movement of the cage. Servo hydraulic cylinders are controlled to adjust the horizontalness of the cage and keep the same tension in the ropes.

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 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 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.
