Auxiliary inspection car device for secondary lining quality

The invention provides an auxiliary inspection car device for secondary lining quality. The auxiliary inspection car device comprises a car frame, a movable supporting pipe and an antenna, wherein the movable supporting pipe is fixed to the top of the car frame, and the antenna is fixed to the top of the movable supporting pipe. The movable supporting pipe comprises multiple articulated mechanisms, a diagonal bracing mechanism, a fine adjustment structure, a sleeve structure and a damping mechanism, wherein the diagonal bracing mechanism and the fine adjustment structure limit the relative movement angle between an upper articulation piece and a lower articulation piece, the sleeve structure enables the antenna to stretch and contract in the vertical direction, and the damping mechanism is in the horizontal direction and the vertical direction. The auxiliary inspection car device for secondary lining quality can continuously and accurately inspect secondary lining at the arch waist position and the arch crown position of a tunnel, is good in inspection effect, can achieve the purposes of cost reduction, continuous inspection and reduction of the number of matching personnel, and optimizes quality inspection of secondary lining of highway tunnels.
