[0045] Specifically, the control room 15 is used to operate the start, stop and movement of the entire device, and to protect the safety of users to avoid accidents caused by delivery during hoisting. The reinforcement plate 21 can effectively improve the structural strength of the hollow support plate 3, and avoid production accidents caused by structural damage due to excessive counterweight during the test process. The model of the asynchronous motor 10 is Y500-6.

[0046] Working principle: When movement is required, the hydraulic jack 20 is started to move the hollow support plate 3 upward, while the fixing rod 8 fixes the fixing plate 5 to keep it in place. When the hollow support plate 3 reaches a certain height, the crawler track 6 will touch the ground. Then the asynchronous motor 10 is started to drive the second bevel gear 9 to rotate, and then the first bevel gear 7 is driven to rotate, thereby driving the crawler track 6 to rotate through the transmission shaft 4 to drive the entire device to move. After reaching the specified position, the asynchronous motor 10 is stopped and the hydraulic jack 20 is started to press the hollow support plate 3 downward until the crawler track 6 leaves the ground and the entire device can no longer move.
