Description
PCT/CN2015/093753 wo 2016/070804
HOIST SYSTEM AND METHOD FOR CONTROLLING THE HOIST SYSTEM TECHNICAL FIELD
[0001] The present invention relates to a method for controlling a hoist system, and a hoist system, and specifically relates to a method for controlling a hoist system, and a hoist system, for loading and unloading a conveyance, such as a cage, used in a mine shaft.
BACKGROUND ART
[0002] Shaft hoisting is broadly used in mining process. When the shaft becomes deeper, the rope (such as a steel rope) that drags the conveyance becomes longer, and appears as an elastic body with great elasticity. There are in most cases a significant rope stretch because of the suspended load. This feature renders the conveyance (such as cage or skip) hard to stop precisely when the conveyance reaches a deep working level. Especially, the rope would be severely deformed when the load on the conveyance is heavy, resulting in upwards and downward movements and leftwards and rightwards shake of the conveyance, and thus causing difficulties to obtain a safe operation.
[0003] Up to now, various cage hoist systems used in auxiliary shaft primarily comprise a driving system and a cage stabilizing system. In the process of loading and unloading the hoist, conventional controlling methods may be divided into two types according to their operation principle: one is to fix the conveyance by upper and lower locking arms which can be extended out by hydraulic work station; the other is by overfalling the rope and then pushing conveyance from lower side through hydraulic work station. Both controlling methods use separate driving system and cage stabilizing system, and thus need to frequently operate the hoist and hydraulic work station respectively. This decreases the operation efficiency of the hoist system, and puts a high requirement on the mechanical strength of the upper and lower locking arms and the performance of the hydraulic work station, which increases the system cost without efficiently increasing the stability and safety of the system. In addition, among these methods, no control or optimization is given to the amount of deformation (elongation) of the steel rope, causing the amount of PCT/CN2015/093753 wo 2016/070804 deformation be always large or the same not be effectively controlled. This would shorten the working life of the steel rope and meanwhile decrease the safety of the hoist system. The same problem also exists in skip hoist system in production shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In the following, detailed description of various embodiments of the present invention shall be made with reference to the Drawings. The claimed system and controlling method may be used for hoisting the skip in a production shaft, as well as for hoisting a cage in an auxiliary shaft; however, since the controlling system and method are substantially the same for hoisting a cage and hoisting a skip, for simplicity, the following only describes hoisting of a cage in an auxiliary shaft as an example.
[0023] As shown in Figure 1, the hoist system comprises n cage stabilizing hydraulic work stations, n supporting devices, n local control boxes and a cage stabilizing control cabinet, wherein “n” indicates the number of all the shaft platforms for horizontal loading and unloading. PCT/CN2015/093753 wo 2016/070804 [0024] In the hoist system, the cage stabilizing hydraulic work station provides driving source for the supporting device, and consists of an oil tank, an oil pump, controlling valves and pipes. It enables proper acting on the corresponding hydraulic ram and connecting rod of the supporting device, and meanwhile provides the state feedback to the controlling system.
[0025] The cage stabilizing mechanic device (hereafter referred to as supporting device) is a device for chairing and locking the cage. Each supporting device consists of at least four identical connecting rod structures, and each connecting rod structure primarily consists of a cage chairing connecting rod, a cage locking connecting rod, a cage chairing ram, a cage locking ram, and a connecting rod seat. The cage chairing connecting rod transfers the load of the cage to the shaft wall via the connecting rod seat, the cage locking connecting rod cooperates with the cage chairing connecting rod to lock the cage, the cage chairing ram is collapsible to put the cage chairing connecting rod in a cage chairing position or in a retracted position, and the cage locking ram is collapsible to put the cage locking connecting rod in a locking position or an unlocking position.
[0026] The local control box can signal operation command to the cage stabilizing hydraulic work station and supporting device, and provides state feedback. There are operation buttons and indicator lights on the control box. The control box interiorly employs Profibus-DP sub-station communication module and I/O module, to communicate with cage stabilizing control cabinet.
[0027] The cage stabilizing control cabinet, acting as a controlling core of the cage stabilizing system, employs Profibus-DP to communicate with n local controlling boxes, and therefore, according to a position of a platform at which the cage stops, controls the cage stabilizing hydraulic work station and supporting device to stabilize the cage and provides state feedback. Meanwhile, the cage stabilizing control cabinet communicates with hoisting transmission control systems via Module-Bus, to cooperatively operate the cage stabilizing and the hoisting processes, so that the process of berthing and releasing cage can be safely ensured.
[0028] Figure 2 shows a schematic diagram showing the cooperation among a group of connecting rod structures of a supporting device, cage 10, and shaft 11. PCT/CN2015/093753 wo 2016/070804
In the Figure, the supporting ends of the cage chairing connecting rod 1 and cage locking connecting rod 2 are mounted on the same hinge pedestal, and the cage chairing connecting rod 1 and cage locking connecting rod 2 are driven respectively by the cage chairing ram 5 and cage locking ram 4 to perform the cage chairing and cage locking actions. The hinge pedestals of the cage chairing ram 5 and cage locking ram 4 and the common hinge pedestal of the cage chairing connecting rod 1 and cage locking connecting rod 2 are all mounted on the connecting rod seat 6 which is fixedly mounted on the shaft wall 12. A cradle 3, as a platform device, can be optionally included. The chairing end of the cage chairing connecting rod 1 and the locking end of cage locking connecting rod 2 are respectively provided with slots adapted to the edge of the cage, for chairing and locking the cage.
[0029] The supporting device may be provided at various loading platforms, for supporting the cage when it reaches required positions. The supporting device may always extend to a cage guide, being ready for use, for example, when the supporting device is located at the bottom of the case guide; or the supporting device may usually be in a retracted position, and extend into the case guide only when required for use.
[0030] The method for controlling the hoist system concerns the process of berthing cage and that of releasing cage. As in the present invention the cage is chaired to be positioned, the process of berthing cage employs the upper berthing, i.e., the cage is slowly put in place from the above of the cage chairing connecting rod; while the process of releasing cage employs the upper releasing, i.e., the cage is slowly moved out of the place from the above of the cage chairing connecting rod. The following describes both situations where a cage moving downward from a position higher than the loading platform is berthed and where a cage moving upward from a position lower than the loading platform is berthed.
[0031] (1) A cage moving downward from a position higher than the loading platform is berthed: [0032] As shown in Figure 3, it is assumed that the system chairs a load of 11 ton, conveyance weight of 10 ton, and a total weight of 21 ton. When the cage moves downward and near to the supporting device, the cage speed reduces to 0.1 m/s, and the cage stabilizing control cabinet sends an operation command for PCT/CN2015/093753 wo 2016/070804
Stabilizing the cage. The cage chairing ram extends to push the cage chairing connecting rod out of the shaft and into the cage guide, to get ready for chairing the cage. Once the cage is berthed, the locking ram extends to push out the cage locking connecting rod, to cooperate with the cage chairing connecting rod to fix and lock the cage simultaneously from above and below. After the berthing, the cage stabilizing control cabinet signals the hoisting control cabinet, and the hoisting control cabinet automatically adjusts the torque of the hoisting motor to a value required for a weight of 8 ton, i.e., a torque required for a weight that is 80% of the dead weight of the cage, so that the tension force of the steel rope is decreased from 21 ton to a value lower than the weight of the cage. In this way, in the following process of releasing cage, no excessively large force would be applied onto the steel rope and hoisting motor, which is otherwise applied at the moment of starting the hoisting due to the looseness of steel rope. Meanwhile, the accident that, due to improper adjustment, the cage becomes unstable or suddenly accelerates upwards at the moment of starting the hoisting, can also be avoided, which accident would damage the system and is risky. In addition, through adjusting the tension force of the steel rope to be less than the dead weight of the cage, it can be ensured that the cage would not skip in a large range of position after the weight in the cage is unloaded. It should be appreciated that, the previous numbers are used only for assumption and example purpose, and has no limit on the claimed invention. As to the adjustment amount of the tension force on the steel rope after the berthing, it can be simulated and optimized according to such as characteristics of the steel rope, range of the frequently occupied load, and the use frequency etc., so as to improve the working life of the steel rope while ensuring safety and stability. In a preferred embodiment, after berthing, the torque of the hoisting motor is adjusted to a torque required for a weight of 50% to 80% of the dead weight of the cage, i.e., the hoisting force of the hoisting motor amounts to 50% to 80% of the dead weight of the cage.
[0033] Figure 4 shows the releasing process after the berthing of the cage moving downward. The hoisting control cabinet sends a command for moving upwards, the cage stabilizing control cabinet then immediately sends a command for unlocking, the cage locking ram contracts and withdraws the cage locking connecting rod to unlock the cage. The hoisting control cabinet then sends a PCT/CN2015/093753 wo 2016/070804 8 starting signal. Since the steel rope maintains a tension of 8 ton when the hoisting motor stops, the 8 ton tension will then be used as the preset torque in the starting process and then the hoisting torque can be gradually increased, so that a potential reversed rotation due to the excessively loose steel rope can be avoided. The cage then leaves the cage chairing device, and the cage chairing ram contracts to withdraw the cage chairing connecting rod out of the case guide, and the releasing process is ended.
[0034] (2) A cage moving upward from a position lower than the loading platform is berthed.
[0035] As shown in Figures 5A and 5B, during the process of berthing a cage moving upward, when the cage is close to the supporting device, the hoisting control cabinet reduces the cage speed to 0.1 m/s, at which speed the cage continues to move upward to a position higher than the supporting device, and then the hoisting control cabinet sends a command for stopping. The cage stabilizing control cabinet then sends an operation command for stabilizing the cage, and the cage chairing ram extends to push the cage chairing connecting rod out of the shaft to the case guide, to get ready for chairing the cage. The hoisting control cabinet forces the cage to change the speed direction of the cage, and to move downwards gradually to be berthed. After berthing, the process of locking cage, stopping, and adjusting the torque of the hoisting motor (i.e., adjusting the tension on the rope) will be similar to those adopted in the process of berthing a cage moving downward as describe above.
[0036] As shown in Figure 6, in the cage releasing process after berthing a cage moving upward, the hoisting control cabinet sends a command for moving downward, and the cage stabilizing control cabinet then immediately sends a command for unlocking so that the cage locking ram contracts and withdraws the cage locking connecting rod to unlock the cage. The hoisting control cabinet then changes the speed direction and forces the cage to move upward at a lower speed for a short while and then stop. The cage chairing ram contracts to withdraw the cage chairing connecting rod out of the cage guide, and then the hoisting control cabinet starts the motor to lower the cage.
[0037] During berthing a cage moving upward and releasing the same, the PCT/CN2015/093753 wo 2016/070804 hoisting control cabinet is required to force the preset speed direction of the cage to be changed, so that the system have to temporally bypass the hoist reversion and hoist running direction protection.
[0038] Though the above description is made by using the steel rope as an example, it should be understood that, the claimed invention is not limited to the case where a steel rope is used, instead any other available rope or cable is also possible.
[0039] Though the claimed invention is described with reference to some preferred embodiments, those skilled in the art would appreciate that, various modifications to the formality or details is possible, without deviating from the sprit and protection scope as defined by the attached claims.
