The guide wheel 12 is wound around the rope 11, one end of the rope 11 is connected to a connecting plate 1201, and at least three hooks 13 are connected to the connecting plate 1201. The slide rail 2 is connected to an adjustment rod 3 by welding, and the adjustment rod 3 is used to correct the slide rail 2. The right end of the two-way threaded rod 6 is connected to a torsion ring 7 by welding, and the torsion ring 7 is used to assist in rotating the two-way threaded rod 6. An anti-slip sleeve is sleeved on the torsion ring 7. The rear part of the hoisting body 1 is connected to a guide rod 8 by welding, and the slide rail 2 and the guide rod 8 slide. The rear of the lifting body 1 is connected with a control component module 14 by bolts, and the control component module 14 is electrically connected to the drive motor 9. A scale line 15 is printed on the rear of the lifting body 1. A push rod 16 is connected to the rear of the lifting body 1 by welding. At least three universal wheels 17 are rotatably connected to the bottom of the lifting body 1. The universal wheels 17 are used to assist in moving the lifting body 1. The lifting body 1 also includes a first slider 201, a slide rail 2, a second slider 202 and a bidirectional threaded rod 6. The front of the lifting body 1 is provided with a left-right symmetrical first slider 201. A slide groove 101 is provided, and a second slide groove 102 is provided at the rear of the lifting mechanism. A first slider 201 is slidably connected to the first slide groove 101. A slide rail 2 is connected between the two first sliders 201 by welding. A second slider 202 is connected to the rear of the slide rail 2 by welding. The second slider 202 is slidably connected to the second slide groove 102. A bidirectional threaded rod 6 is rotatably connected to the lifting body 1. The slide rail 2 is threadedly connected to the bidirectional threaded rod 6. The slide rail 2 is moved inward by rotating the bidirectional threaded rod 6.

[0029] When the hoisting mechanism is needed, the maintenance personnel hold the push rod 16 by hand to move the hoisting body 1 to the front of the switch cabinet, then open the switch cabinet, and then hold the torsion ring 7 by hand to rotate the two-way threaded rod 6 to move the two slide rails 2 inward. The maintenance personnel check the distance between the two slide rails 2 through the scale line 15. When the two slide rails 2 move inward to the appropriate position, the maintenance personnel stop rotating the two-way threaded rod 6, and then pull the trolley switch out of the switch cabinet to the hoisting body 1, so that the pulley of the trolley switch enters the slide rail 2, so that the slide rail 2 limits the trolley switch, thereby achieving the purpose of horizontally disassembling the trolley switch.

The output shaft of the driving motor 9 rotates to drive the winding wheel 10 to rotate and reel in the rope 11, so that the rope 11 pulls the connecting plate 1201 and the hook 13 to move upward, and then the trolley switch is hoisted. The maintenance personnel inspect the trolley switch. After the inspection is completed, the output shaft of the driving motor 9 is controlled to reverse, and then the winding wheel 10 is reversed to release the rope 11, so that the connecting plate 1201 and the hook 13 move downward to place the trolley switch on the hoisting body 1, so that the pulley of the trolley switch contacts the guide plate 4, and then the trolley switch is pushed from the hoisting body 1 into the switch cabinet, so as to achieve the effect of horizontally installing the trolley switch.

[0031] Before pulling the trolley switch out of the switch cabinet onto the hoisting body 1, the maintenance personnel moves the guide plate 4 outward, and the reset spring 5 is compressed accordingly. Then the trolley switch is pulled out of the switch cabinet onto the hoisting body 1, so that the pulley of the trolley switch enters the slide rail 2, and then the guide plate 4 is released, and the reset spring 5 returns to its original state, so that the guide plate 4 moves inward and contacts the pulley of the trolley switch, thereby guiding the pulley of the trolley switch, so as to facilitate the smooth pulling out of the trolley switch.
