[0019] Specifically, climbing is performed by using the stair treads 7, which makes it convenient to keep the multiple stair treads 7 in a horizontal state at all times, making it convenient to step on and climb.

[0020] Please refer to Figures 1 to Figure 9 There are several stair treads 7, and one end of the matching block 8 away from the stair tread 7 is rotatably connected to the support rod 6 through a shaft.

[0021] Specifically, the guide pulley 10 plays a role in assisting movement, improving the movement of the bottom end of the stairs, and the cleaning brush 15 conveniently cleans dust and debris inside the track 17 as the guide pulley 10 moves, avoiding affecting the movement of the bottom end of the stairs.

[0022] Please refer to Figures 2 to Figure 7 The outer surface of the guide pulley 10 abuts against the inner wall of the track 17 , and the bottom of the cleaning brush 15 abuts against the inner wall of the track 17 .

[0023] Specifically, the cooperation between the T-shaped slider 13 and the T-shaped slot serves to guide the cleaning brush 15. The setting of the return spring 12 facilitates the cleaning brush 15 to better fit the inner wall of the track 17, making it easier to clean dust and debris.

[0030] Please refer to Figures 1 to Figure 10 The lowest position of the support plate 28 is lower than that of the base frame 2 , and the position of the adjustment disk 30 is located above the adjustment box 25 .

[0031] When in use, the lifting platform 1 is fixedly connected to the external lifting equipment and moves. The lifting platform 1 moves up and down in the vertical direction with the lifting equipment. The lifting platform 1, the stair frame 5, the support rod 6, the stair tread 7 and the matching block 8 form a parallelogram structure. The lifting platform 1 is parallel to the stair tread 7, and the support rod 6 is parallel to the stair tread 7. The lifting platform 1 is always in a horizontal state. The change in the height of the lifting platform 1 makes the inclination angle of the stair frame 5 and the support rod 6, and then the stair tread 7 is always in a horizontal state, which is convenient for users to climb for transformer assembly work. The position of the base frame 2 corresponds to the position of the lifting platform 1. The corresponding positions of the base frame 2 and the lifting platform 1 are adjusted by moving the universal wheel 24. Before the lifting work is carried out, the position of the base frame 2 is supported and fixed to prevent the position of the base frame 2 from being offset during lifting. The adjusting disk 30 is rotated to rotate the threaded rod 26. The threaded rod 26 is transmission-connected to the threaded ring block 27, and the guide rod 29 passes through the guide hole, so that the threaded ring block 27 moves along the length direction of the guide rod 29, so that the position of the support plate 28 moves downward, so that the support plate 28 abuts against the ground, which is convenient for supporting the base frame 2. The inclination angle of the stair frame 5 changes, providing a horizontal component of force for the U-shaped plate 9. The guide pulley 10 moves inside the track 17. The auxiliary pulley 22 and the H-shaped plate 21 are inside the U-shaped guide plate 18, which play a role in assisting movement and limiting. The cross plate 19 is fastened to the U-shaped plate 9 by the second bolt 23, which facilitates the disassembly of the auxiliary pulley 22 and the H-shaped plate 21. The cleaning brush 15 moves with the movement of the U-shaped plate 9, and the cleaning brush 15 abuts against the inner wall of the track 17, which facilitates the movement to clean the dust and debris in the track 17 and push the dust and debris to the The two ends of the track 17 avoid affecting the movement of the guide pulley 10. The elastic tension of the return spring 12 facilitates the cleaning brush 15 to better abut against the inner wall of the track 17, thereby improving the cleaning effect. Conversely, when removing the cleaning brush 15, the L-shaped plate 14 and the cleaning brush 15 are moved upward to move the T-shaped slider 13 along the length direction of the T-shaped slide groove, so that the return spring 12 is forced to contract, and then the first bolt 16 is screwed to disengage the first bolt 16 from the first threaded hole, thereby facilitating the separation of the cleaning brush 15 from the L-shaped plate 14, facilitating the disassembly and replacement of the cleaning brush 15, and improving practicality.
