Tunnel detection equipment lifting device

The utility model provides a lifting device of tunnel detection equipment, and aims to solve the technical problems of high labor intensity and low detection efficiency of tunnel detection. Accordingto the technical scheme, the lifting device of the tunnel detection equipment comprises a rotating disc, a hollow column, a lifting column and a clamping jaw. The bottom end of the hollow column is hinged to the rotating disc and matched with a hydraulic cylinder used for adjusting the angle of the hollow column. A lead screw driven by a second servo motor is arranged in the hollow column, and anopen groove extending in the length direction is formed in one side wall of the hollow column. The lifting column and the hollow column are arranged in parallel and are fixedly connected with the screw rod nut of the screw rod through the open groove; the clamping jaw is composed of a plurality of L-shaped clamping strips distributed on the peripheral side of the upper portion of the hollow column. The clamping strip is pr
