The jack 2 is started, and the jack 2 lifts the supporting plate 3 and contacts the top of the frame to provide supporting force for the frame. When the frame needs to be lowered, the suspension device releases the frame. At this time, the jack 2 drives the supporting plate 3 to descend, and then the frame is lowered. When the frame needs to be inspected or assembled, the staff climbs to the top of the device through the lifting ladder 5, and then holds the handrail 4 to inspect or assemble the frame. In the process of lowering the frame, the frame needs to be protected, and the connecting plate 6 is inserted into the clamping groove 62 through the clamping plate 63, which can be quickly lowered. The connecting plate 6 and the protective plate 61 are quickly installed on the supporting plate 3.

At the same time, the connecting plate 6 is inserted into the trapezoidal positioning groove 64 through the trapezoidal clamping plate 67. After the inclined surface of the trapezoidal clamping plate 67 contacts the inclined surface of the positioning rod 66, the positioning rod 66 is pushed to retract into the limiting sleeve 65 through the guidance of the inclined surface. When the trapezoidal clamping plate 67 is fully inserted into the trapezoidal positioning groove 64, the spring drives the positioning rod 66. The positioning rod 66 pops out of the limiting sleeve 65 and is inserted into the through hole to lock the trapezoidal clamping plate 67, thereby locking the connecting plate 6 and the protective plate 61, thereby improving the installation stability. After the connecting plate 6 and the protective plate 61 are disassembled, it is more convenient to inspect and install the frame.

[0017] Working principle: during the descent of the frame, the J-shaped clamping rod 74 and the clamping plate 76 clamp the frame to prevent the frame from shaking, thereby improving the stability of the device frame when it is descending and preventing the frame from shaking. After the clamping plate 76 is in contact with the surface of the frame, it can rotate along the second connecting rod 75 according to the shape of the frame, thereby enhancing the clamping force. When the support plate 3 moves upward, it drives the telescopic elastic rod 711 and the contact plate 712 to move upward. After the contact plate 712 contacts the lower surface of the frame, it squeezes the telescopic elastic rod 711 and approaches the support plate 3, thereby driving the transmission pressure block 713 to descend and insert into the through groove 710.

Sliding the support plate 82 in the swivel rail 81 can further increase the support area and improve the support stability of the device. Rotate the swivel rail 81 to lift the support plate 82 so that the support plate 82 and the mobile base are aligned. 1 is vertically arranged, at this time, the locking link 87 is inserted into the locking plate 84, and the locking link 87 locks the rotating slide rail 81 and the support plate 82, thereby reducing the footprint of the device and facilitating the movement and storage of the device. During the lowering process of the frame, the slide bar 78 approaches the J-shaped clamp rod 74 and is driven by the top inclined surface of the locking link 87 to move upward and disengage from the locking plate 84.
