[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

An elastic member 26 is fixedly installed between one side and a frosted strip 28 is fixedly connected to the inner wall of the vertical slide column 22. The side of the bonding plate 25 away from the elastic member 26 is movably connected to the side of the frosted strip 28. The initial elastic force of the elastic member 26 can make the bonding plate 25 close to the side of the frosted strip 28. The static friction between the bonding plate 25 and the frosted strip 28 locks the vertical slide column 22 in the inner cavity of the support sleeve 21 to avoid the problem that the lifting platform 29 falls directly when the lifting structure is damaged. The material of the bonding plate 25 is set to iron alloy. The control electromagnet 27 is energized to magnetically attract the bonding plate 25, thereby creating a gap between the bonding plate 25 and the frosted strip 28, thereby avoiding the problem that the bonding plate 25 interferes with the lifting and lowering of the vertical slide column 22 inside the support sleeve 21.

[0029] As an implementation method in this embodiment, Figure 1 、 Figure 2 As shown, a guardrail 291 is fixedly installed on the top of the lifting platform 29, and a track rod 292 is fixedly installed on the outer wall inside the guardrail 291. A sliding block 293 is slidably connected to the outer wall of the track rod 292, and an elastic rope 294 is fixedly connected to the outer wall of the sliding block 293. The end of the elastic rope 294 away from the sliding block 293 is fixedly connected to the connecting block 295, and a nylon belt 296 is fixedly connected to the outer wall of the connecting block 295. The end of the nylon belt 296 away from the connecting block 295 is fixedly connected to the safety belt buckle 297. The safety belt buckle 297 is an existing male-female buckle structure. The safety belt buckle 297 is disassembled, and then the nylon belt 296 is put on the user's waist, and then the safety belt buckle 297 is assembled, thus completing the safety protection treatment for the user. The design of the track rod 292 and the sliding block 293 makes it easy for the user to move on the top of the lifting platform 29.

[0030] As an implementation method in this embodiment, Figure 1 、 Figure 4 、 Figure 5As shown, the hydraulic lifting mechanism 3 includes a hollow bar 31 and an extension platform 33. The top of the hollow bar 31 is fixedly connected to a hollow cylinder 32, and the hollow cylinder 32 is fixedly installed at the bottom of the bottom support frame 1. A sealing slider 321 is slidably connected to the inner wall of the hollow cylinder 32. A lifting rod 322 is fixedly installed on the top of the sealing slider 321. The top of the lifting rod 322 extends to the top of the bottom support frame 1 and is fixedly connected to the bottom of the lifting platform 29. The extension platform 33 is fixedly installed on the outer wall of the bottom support frame 1. An oil storage tank 34 is fixedly installed on the top of the extension platform 33. The top of the hollow bar 31 is fixedly connected to a solenoid valve 35. The top of the solenoid valve 35 is fixedly connected to a connecting pipe 36. The end of the connecting pipe 36 away from the solenoid valve 35 is fixedly connected to the top of the oil storage tank 34. The extension platform 33 An oil pump 37 is fixedly installed on the top, and the input pipe of the oil pump 37 extends to the bottom of the inner cavity of the oil storage tank 34. The output pipe of the oil pump 37 is fixedly connected to the top of the hollow bar 31. The inner cavity of the oil storage tank 34 is filled with hydraulic oil. By controlling the operation of the oil pump 37, the hydraulic oil inside the oil storage tank 34 can be extracted and transported to the inner cavity of the hollow bar 31. The hollow bar 31 can connect the inner cavities of the three hollow cylinders 32. The hydraulic oil then enters the bottom of the inner cavity of the hollow cylinder 32, pushing the sealing slider 321 to move upward, and the lifting platform 29 is raised through the transmission of the lifting rod 322. The solenoid valve 35 is controlled to open. Under the action of the overall gravity of the lifting platform 29, the hydraulic oil inside the hollow cylinder 32 is prompted to flow back to the oil storage tank 34, completing the lowering of the height of the lifting platform 29.

[0031] Working principle: When in use, the oil pump 37 is controlled to work, the hydraulic oil inside the oil storage tank 34 is extracted and transported to the inner cavity of the hollow cylinder 32, pushing the sealing slider 321 to move upward, and the lifting platform 29 is raised by the transmission of the lifting rod 322, and the solenoid valve 35 is controlled to open. Under the action of the overall gravity of the lifting platform 29, the hydraulic oil inside the hollow cylinder 32 is prompted to flow back into the oil storage tank 34, completing the lowering of the height of the lifting platform 29. Before performing the lifting work, the electromagnet 27 is controlled to be energized, which can magnetically attract the bonding plate 25, causing a gap to be generated between the bonding plate 25 and the frosting strip 28. After the lifting work is completed, the electromagnet 27 is turned off, and the initial elastic force of the elastic member 26 can make the bonding plate 25 close to the side of the frosting strip 28, thereby locking the height of the lifting platform 29.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
