[0023] When it is necessary to lift the power equipment during the construction of the power project, the staff will place the power equipment on the placement plate 3, and fit the base 1 and the silicone pad of the placement plate 3 tightly against the outer wall of the pole. Then the staff will start the driving component 7 through the controller. The driving component 7 controls the two rotating blocks 4 to rotate in the U-shaped storage groove 101. The two rotating blocks 4 drive the sleeve 401 to disengage from the U-shaped storage groove 101 until the abutment limiting component 8 contacts the outer wall of the two sleeves 401 to ensure that it is in a vertical state. At the same time, the lifting component 6 and the two hydraulic cylinders 402 start to work, and the lifting component 6 tightens the wound pull rope 603. Relax, and as the top block 403 and the guide wheel 604 move upward, the relaxed pull rope 603 is straightened to keep the tension of the pull rope 603 stable, and then the lifting component 6 works in reverse to lift the placement plate 3 by the pull rope 603, and the abutment and limiting component 8 moves along the outer wall of the sleeve 401 following the movement of the placement plate 3, ensuring that the placement plate 3 always remains horizontal during the lifting process, so as to ensure the smoothness and safety of the lifting process, and lift the power equipment to the required height, and the lifting component 6 can share part of the weight of the power equipment, reduce the force on the hydraulic cylinder 402, and reduce the risk of damage to the hydraulic cylinder 402 due to long-term or excessive force; Thereby, the overall structure of the device is more compact when not in use, which saves space and is convenient for storage and transportation, thus solving the problem that the existing device is troublesome to store and occupies a large space after the lifting operation is completed.

[0025] When it is necessary to unfold, the forward and reverse motors 707 work, and their output ends drive the worm 708 to rotate, and the worm 708 drives the meshing worm wheel 706 to rotate, so that the transmission shaft 703 rotates, and then the first sprocket 702 is controlled to rotate through the two second sprockets 704 and the transmission chain 705, and the two shafts 701 rotate accordingly, and drive the rotating block 4 to rotate in the U-shaped storage groove 101, and then when the hydraulic cylinder 402 works, the driving motor 606 works, and its output end controls the winding roller 601 to rotate through the reducer 607 to relax the tightened pull rope 603, at this time, the two guide wheels 604 follow the top block 403 to move upward to straighten the relaxed pull rope 603, and after the top block 403 reaches the predetermined height, the hydraulic cylinder 402 stops working, and the position of the guide wheel 604 is fixed to ensure that the pull rope 603 maintains appropriate tension; Then the driving motor 606 works in reverse to reel in the pull rope 603, the pull rope 603 is tightened again, guided by the guide wheel 604, and the placement plate 3 is lifted up through the mounting plate 605 until the placement plate 3 and the power equipment reach the specified height of the pole, thus completing the lifting of the power equipment; After the use is finished and the placement plate 3 is reset, the hydraulic cylinder 402 contracts to make the top block 403 descend, and the drive motor 606 runs in the reverse direction at the same time. The speed reducer 607 controls the winding roller 601 to rotate again, and the pull rope 603 is gradually rewound to ensure that the pull rope 603 returns to the initial state. At this time, the forward and reverse motors 707 work in the reverse direction, so that the rotating block 4, the sleeve 401 and the guide wheel 604 rotate back to the U-shaped storage groove 101, wherein the vertical plate 2 can support the pull rope 603 to avoid contact with the shaft of the drive motor 606 during storage. The whole system enters the standby state again, ready for the next power equipment lifting task, saving space, and facilitating storage and transportation. At the same time, through the coordinated use of components such as the hydraulic cylinder 402 and the pull rope 603, part of the weight of the power equipment can be shared, the force on the hydraulic cylinder 402 is reduced, and the risk of damage to the hydraulic cylinder 402 due to long-term or excessive force is reduced.

[0026] See also Figure 4 and Figure 6As shown, the abutment limiting assembly 8 includes two horizontal rods 801, and a fixed block 802 is welded to the outer wall of one end of the two horizontal rods 801 away from the placement plate 3, and a moving block 804 is inserted into the end of each of the fixed blocks 802 away from the horizontal rod 801, and an abutment block 805 is welded to the top of each of the moving blocks 804, and the arc surface of each of the abutment blocks 805 is in sliding contact with the outer wall of the sleeve 401, and a square groove 8021 is opened on the end surface of each of the fixed blocks 802 away from the horizontal rod 801, and a support spring 803 is arranged in each of the square grooves 8021, and each of the moving blocks 804 is provided with a support spring 803. 04, one end close to the fixed block 802 is slidably placed in the square groove 8021 and in sliding contact with the groove wall, and the two ends of each of the support springs 803 are respectively fixedly connected to the square groove 8021 and the moving block 804, and the lower surface of the end of each of the moving blocks 804 away from the fixed block 802 is provided with a guiding slope 8041, and the lower surfaces of the ends of the two horizontal rods 801 away from the fixed block 802 are fixed with screws on the upper surface of the placement plate 3, and a limiting plate 301 is provided on the outer side of the upper surface of the placement plate 3, wherein the guiding slope 8041 can ensure that the moving block 804 is pushed by the top of the sleeve 401 when moving downward.

[0027] When the rotating block 4 drives the sleeve 401 to rotate to the vertical direction, the outer wall of the sleeve 401 will contact the arc surface of the abutment block 805. As the sleeve 401 gradually becomes vertical, the abutment block 805 will push the moving block 804 to move into the square groove 8021 and squeeze the support spring 803 until the moving block 804 reaches the maximum depth position. At this time, the sleeve 401 is in a vertical state, and the support spring 803 reaches the maximum compression state. When the placement plate 3 moves upward, the fixed block 802 is driven to move through the horizontal rod 801, and the fixed block 802 drives the moving block 804 and the abutment block 805 to move. When it moves to the top of the sleeve 401, since the diameter of the telescopic rod of the hydraulic cylinder 402 is smaller than the diameter of the sleeve 401, the support spring 803 will push the moving block 804 to move outward and make the abutment block 805 contact the outer wall of the telescopic rod of the hydraulic cylinder 402, ensuring that the placement plate 3 always remains horizontal during the lifting process, so as to ensure the smoothness and safety of the lifting process and lift the electrical equipment to the required height.

[0028] The working principle of the present invention is: When it is necessary to lift the power equipment during the construction of the power project, the staff will place the power equipment on the placement plate 3, and fit the silicone pads of the base 1 and the placement plate 3 tightly against the outer wall of the pole, and then the staff will start the forward and reverse motor 707 by the controller, and its output end will drive the worm 708 to rotate, and the worm 708 will drive the meshing worm wheel 706 to rotate, so that the transmission shaft 703 will rotate, and then the first sprocket 702 will be controlled to rotate through the two second sprockets 704 and the transmission chain 705, and the two shafts 701 will rotate accordingly, and drive the rotating block 4 to rotate in the U-shaped storage groove 101, and the rotating block 4 will drive the sleeve 401 to rotate, and the outer wall of the sleeve 401 will contact the arc surface of the abutment block 805, and as the sleeve 401 gradually becomes vertical, the abutment block 805 will push the moving block 804 to move into the square groove 8021, and squeeze the support spring 803 until the moving block 804 reaches the maximum depth position, at which time the sleeve 401 is in a vertical state; Then, the hydraulic cylinder 402 works, and its telescopic rod pushes the top block 403, the guide wheel 604 and the connecting rod 6041 to move upward. When the hydraulic cylinder 402 works, the driving motor 606 works, and its output end controls the winding roller 601 to rotate through the reducer 607 to loosen the tightened rope 603. At this time, the two guide wheels 604 follow the top block 403 to move upward to straighten the loose rope 603. After the top block 403 reaches a predetermined height, the hydraulic cylinder 402 stops working, and the position of the guide wheel 604 is fixed to ensure that the rope 603 maintains appropriate tension. Then the driving motor 606 works in reverse to reel in the pull rope 603, the pull rope 603 is tightened again, guided by the guide wheel 604, and the placement plate 3 is pulled up through the mounting plate 605, and the placement plate 3 will drive the fixed block 802 to move through the horizontal rod 801, and the fixed block 802 will drive the moving block 804 and the abutment block 805 to move. When it moves to the top of the sleeve 401, since the diameter of the telescopic rod of the hydraulic cylinder 402 is smaller than the diameter of the sleeve 401, the support spring 803 will push the moving block 804 to move outward and make the abutment block 805 contact the outer wall of the telescopic rod of the hydraulic cylinder 402 until the placement plate 3 brings the power equipment to the specified height of the pole, completing the lifting of the power equipment.
