[0025] See also Figure 3-4The lifting structure 2 includes a lifting frame 21, which is fixedly connected to the movable bottom plate 1. Two through slots 22 are provided on both sides of the top of the lifting frame 21. Supports 23 are installed on both sides of the top of the lifting frame 21. A crossbar 24 is rotatably installed inside the two supports 23. Sprockets 25 are installed on both sides of the outer surface of the crossbar 24. A pulley 26 is installed at one end of the crossbar 24. A crossbar 27 is rotatably installed inside the lifting frame 21.

The two fixing blocks 214 are fixedly connected to the two chains 211 .
[0026] The pulley 1 26 and the pulley 2 34 are connected by a belt 35, so that the cross bar 1 24 can drive the two sprockets 1 25 to rotate, thereby allowing the two chains 211 to rotate on the outer surfaces of the four sprockets 28. Since the lifting plate 213 is fixed to one end of the chain 211 by two fixing blocks 214, when the two chains 211 rotate, the lifting plate 213 can be driven to move horizontally up and down, thereby completing the lifting function.
[0027] See also Figure 3 and Figure 6 The two buffer structures 5 include buffer springs 51, one end of the bottom of the two buffer springs 51 is fixedly connected to the two bottom support plates 29, a top plate 52 is installed on the top of the two buffer springs 51, the two top plates 52 are slidably connected to the sliding rod 210, and a buffer pad 53 is installed on the top of the two top plates 52.
[0028] When the two first rotating rods 48 cannot prevent the lifting plate 213 from falling, the two buffer springs 51 and the buffer pad 53 can be arranged to buffer the impact caused by the lifting plate 213 when it falls, so as to reduce the damage to the lifting plate 213 and the electrical equipment placed on the top of it.
[0029] See also Figure 2 The driving structure 3 includes a mounting frame 31, two fixing frames 32 are installed inside the mounting frame 31, and servo motors 33 are installed inside the two fixing frames 32. A pulley 2 34 is installed at one end of the output shaft of the servo motor 33, and a belt 35 is sleeved on the outer surface of the pulley 2 34, and the belt 35 is sleeved and connected with the pulley 1 26.
[0030] The servo motor 33 is driven to make its output shaft drive the pulley 2 34 to rotate. Since the pulley 2 34 is connected to the pulley 1 26 through the belt 35, the pulley 1 26 can drive the cross bar 1 24 to rotate, thereby providing power for the lifting work.
[0031] Working principle, when a lifting structure is used, in the initial state, first, move the device to the lifting point, place the power equipment on the lifting plate 213, and then drive the servo motor 33 to drive the output shaft of the servo motor 33 to drive the pulley 2 34 to rotate. Since the pulley 2 34 is connected to the pulley 1 26 through the belt 35, the pulley 1 26 can drive the cross bar 1 24 to rotate. The rotation of the cross bar 1 24 can drive the two sprockets 1 25 to rotate, thereby allowing the two chains 211 to rotate on the outer surfaces of the four sprockets 28. Since the lifting plate 213 is fixed to one end of the chain 211 through two fixing blocks 214, when the two chains 211 rotate, the lifting plate 213 can be driven to move horizontally up and down, thereby completing the lifting function. When the lifting plate 213 rises to the specified position and stops, the second rotating rod 410 drives the second bevel gear 412 to rotate by rotating the two turning handles 411 respectively. Since the second bevel gear 412 The outer surface is meshed with the outer surface of the first bevel gear 45, so the rotation of the second bevel gear 412 can drive the threaded rod 44 to rotate. Due to the limit of the clamping strip 47 stuck in the sliding groove 43, the threaded tube 46 can move horizontally upward on the outer surface of the threaded rod 44. When the two threaded rods 44 rise to the bottom of the lifting plate 213, the two first rotating rods 48 are rotated to make them resist the bottom of the lifting plate 213. At this time, the lifting plate 213 can be supported to avoid the lifting plate 213 from falling rapidly when the chain 211 breaks or the servo motor 33 is overloaded and short-circuited, which may cause harm to the operator. If an emergency occurs and the two first rotating rods 48 cannot prevent the lifting plate 213 from falling, the two buffer springs 51 and the buffer pad 53 can be set to buffer the impact of the lifting plate 213 when it falls, so as to reduce the damage to the lifting plate 213 and the electrical equipment placed on the top of it.
