[0010] Through the above technical solution, when the lifting plate moves, the lifting plate can drive the vertical rod to move, and the movement of the vertical rod can drive the sliding plate to move inside the rectangular tube, so that the lifting plate moves more smoothly.
[0011] Furthermore, the top end of the rectangular tube is fixedly connected to the bottom of the detection trolley body, and the bottom end of the vertical rod is fixedly connected to the top surface of the lifting plate.
[0012] Through the above technical solution, the limit assembly is fixedly connected between the lifting plate and the detection trolley body.
[0013] Furthermore, the left end of the bidirectional screw rod extends to the outer side of the support plate close to the left end of the detection trolley body, and the left end of the bidirectional screw rod is fixedly connected with a rotating handle.

[0017] In summary, this application includes the following beneficial technical effects:
[0018] When it is necessary to move the inspection trolley body, the handle is turned to drive the bidirectional screw rod to rotate. The rotation of the bidirectional screw rod causes the two sliding blocks to move relative to each other on the outside of the sliding rod, and the action of the connecting rod causes the lifting plate to move downward. The downward movement of the lifting plate drives the roller to move downward, so that the bottom side height of the roller is lower than the lowest point of the inspection trolley body, so that the roller contacts the ground, thereby making it convenient to use the roller to move on the ground to drive the inspection trolley body to move, without manual handling, saving workers' physical strength and reducing workers' workload.
