Moving device for track detection robot

The utility model relates to a moving device for a track detection robot, which is mounted on a chassis of the track detection robot and comprises a plurality of trundle lifting mechanisms, and each trundle lifting mechanism comprises a mounting frame, a universal wheel mounted at the lower end of the mounting frame and a lifting device mounted at the upper end of the mounting frame. The lifting device comprises a sliding sleeve, a sliding block and a fixing structure, the sliding block is contained in the sliding sleeve and can ascend and descend relative to the sliding sleeve, and the sliding sleeve and the sliding block are fixed through the fixing structure. According to the track detection robot, the plurality of trundle lifting mechanisms are arranged on the chassis of the track detection robot, so that the whole track detection robot can move through the trundle lifting mechanisms, the friction force is small, the movement is smooth, the counter electromotive force generated by the motor when the track
