It can be appreciated that through the arrangement of the plurality of hydraulic support legs 409, effective support can be formed to the both sides of first flatcar 405 and second flatcar 406, and through the arrangement of second driving piece and support arm 408, the support position of hydraulic support legs 409 can be adapted to different ground environment in tunnel 1, from this, the problem that the first flatcar 405 and second flatcar 406 appear the side to roll when using, even warp, guarantee the stable setting of first lift platform 401 and second lift platform 402 on first flatcar 405 and second flatcar 406.

It should be noted that, the specific type of the second driving member may be set according to actual needs, which is not limited to this, and the second driving member may be, for example, a hydraulic cylinder, where a cylinder end of the hydraulic cylinder is hinged to the first flatcar 405, and a piston rod end of the hydraulic cylinder is hinged to the support arm 408, so that extension and retraction of the support arm 408 is implemented under the driving of the hydraulic cylinder.

The specific type of the hydraulic support leg 409 may be set according to actual needs, which is not limited by this, and by way of example, the hydraulic support leg 409 on the first flatcar 405 includes an outer cylinder, an inner cylinder and a sixth driving member, the outer cylinder is disposed on the support arm 408, the inner cylinder is slidably disposed at one end of the outer cylinder far away from the support arm 408, the sixth driving member is disposed on the outer cylinder, and the sixth driving member is in transmission connection with the inner cylinder, thereby realizing extension and retraction of the inner cylinder under the driving of the sixth driving member.

The sixth driving piece can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged to the outer cylinder, and the piston rod end of the hydraulic cylinder is hinged to the inner column, so that the inner column is stretched under the driving of the hydraulic cylinder.
