Embodiment Construction

[0041] Such as figure 1 As shown, the present invention adopts the inverted plane triangular frame structure as the bottom support and the sliding system of the whole inspection vehicle, and installs direction control equipment and components for placing the geological radar host at the rear. Then set a planar splint in the middle of the bottom plane, set a vertical movable support tube in the center of the splint, and place a 400M antenna at its end to realize detection. The 400M antenna is equipped with a ship-type anti-blocking shell device. It avoids unevenness and secondary lining misalignment encountered during the forward movement of the inspection vehicle, ensuring smooth and continuous inspection.

[0042] The frame of the testing vehicle is triangular in shape, and the main engine is placed on one corner end. A flat splint is arranged in the middle of the frame, and the movable support tube is fixed on the flat splint. The vehicle frame also includes several connec...

Abstract

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.

Description

technical field [0001] The invention relates to an auxiliary inspection vehicle device for secondary lining quality, in particular to an auxiliary inspection vehicle device for a geological radar 400M antenna used in the secondary lining quality inspection of highway tunnels. Background technique [0002] The inspection of the secondary lining quality is a very important content in the completion acceptance of highway tunnels. At present, ground radar combined with a 400M antenna is generally used for detection. Five survey lines need to be arranged along the tunnel's vault, both sides of the arch, and both sides of the side wall. [0003] At present, the secondary lining quality inspection of highway tunnels is generally carried out in two ways: [0004] (1) Highway tunnel inspection vehicle [0005] The road tunnel inspection vehicle can perform the inspection of road tunnels well, but it cannot be popularized in tunnel inspection due to the following three characteristi...
