The mounting block 10 can be slidably connected to the support rod 8 by means of a limiting slide groove and a pulley, so that the mounting block 10 can slide along the support rod 8. A pillar 11 is provided on the mounting block 10, and the pillar 11 includes a bottom cylinder and an adjustment cylinder inserted on the bottom cylinder. The bottom tube and the adjustment tube can realize the height adjustment of the pillar 11 by means of jacks and pins (both the bottom tube and the adjustment tube are provided with a plurality of jacks in the vertical direction. When the jacks on the bottom tube and the adjustment tube are coaxial, the fixing is achieved by the pins). A placement slot 12 is provided on the adjustment end of the pillar 11. The length of the placement slot 12 is adjustable. In specific applications, the size of the operating platform 6 can be designed to be 0.8 to 1.0 meters wide, the height of the guardrail 7 can be designed to be 0.6 to 0.8 meters, the longest length of the pillar 11 can be designed to be 0.5 to 0.7 meters, and the maximum telescopic length of the placement slot 12 can be designed to be 0.8 to 1.1 meters.

At this time, the placement groove 12 is placed firmly. With this design, the support tube provides a good supporting force for the placement groove 12, which can prevent the placement groove 12 from being disturbed or even broken at the end away from the support 11 when the maintenance tool placed in the placement groove 12 is too heavy.

[0028] In another technical solution, the manner in which the mounting block 10 slides in a limited position along the length direction of the support rod 8 is specifically as follows: a plurality of slide grooves along the length direction are provided on the side wall of the support rod 8, a through hole is opened in the middle of the mounting block 10, a plurality of pulleys are provided on the inner wall of the through hole, the plurality of pulleys correspond one-to-one to the plurality of slide grooves, and the pulleys extend into the corresponding slide grooves and move along the corresponding slide grooves. Preferably, the number of the slide grooves may be four, which are distributed in the up, down, left and right directions of the support rod 8. The beneficial effect obtained by adopting this technical solution is that a manner in which the mounting block 10 is connected to the support rod 8 in a limited sliding manner is provided, so that the mounting block 10 can slide firmly along the support rod 8 and rotation of the mounting block 10 is avoided.

A pair of opposite first fixing plates 506 are vertically arranged on the top of the base 1. The folding assembly is arranged between the pair of first fixing plates 506. Each first fixing plate 506 is provided with a parallel first slide groove 504. A first sliding member 502 is slidably arranged on each first slide groove 504. The two pairs of legs 501 at the bottom are bottom legs 501. A first cross bar is rotatably connected between the two legs 501 at the same end of the bottom legs 501. The two legs 501 at the end of the bottom legs 501 are respectively hinged to the pair of first fixing plates 506.

The hydraulic rod 503 is connected to the hydraulic pump. The control system controls the hydraulic pump to drive the hydraulic rod 503 to telescope so as to open or fold the folding assembly; the structure of the first sliding member 502 is consistent with that of the second sliding member 508, which is a common result, for example, including a slider (matched with the corresponding slide groove) and a transverse axis, the slider slides along the corresponding slide groove, and the bottom leg and the top leg are hinged to the corresponding transverse axis;

[0030] The beneficial effect obtained by adopting this technical solution is that by setting up the scissor fork lifting mechanism 5, compared with other lifting mechanisms, when the device is not in use, the volume occupied by the lifting device in the vertical direction can be reduced, which is convenient for storing the entire device and improves portability.

[0031] In another technical solution, each mounting plate 9 is hinged to the guardrail 7, and the mounting plate 9 is hinged in the direction of rotation along the vertical plane. It also includes a locking member, which is used to fix the position of the mounting plate 9. The way the mounting plate 9 is hinged and the structure of the locking member are well known to those skilled in the art. Here is an implementation structure: each mounting plate 9 is provided with vertical plates on both sides, and a cross bar is provided between the two vertical plates. The cross bar is fixedly connected to the two vertical plates. The mounting plate 9 is rotatably penetrated on the cross bar so that the mounting plate 9 rotates around the cross bar (that is, rotates in the vertical plane). The mounting plate 9 and a pair of vertical plates are provided with through holes. When the three through holes are coaxial, the mounting plate 9 is vertical (the placement slot 12 is horizontal at this time), and the mounting plate can be penetrated through the three through holes by a latch 17. 9 is fixed in position; during use, when the lifting platform is used up, the scissor fork lifting mechanism 5 is driven to retract to the minimum volume, the maintenance personnel get off the operating platform 6, and then remove the support tube from the bottom of the placement slot 12 (if a support tube is used), and place the support tube on the operating platform 6 (a horizontal placement slot can be opened on the operating platform 6 for placing the support tube), adjust the length of the placement slot 12 to the shortest, and then remove the pin 17 from the three perforations, rotate the mounting plate 9 to make the pillar 11 horizontal, at this time, the placement slot 12 is located within the space range of the guardrail 7, which can reduce the vertical space occupied by the pillar 11 and the placement slot 12, and cooperate with the scissor fork lifting mechanism 5, The volume occupied by the device in the vertical direction can be reduced as a whole, which is convenient for storage, thereby improving the portability of the device.
