Abstract

The invention discloses a tunnel lining detection device which comprises a basic platform (10), a tunnel side wall detection mechanism (20), a tunnel haunch detection mechanism (30) and a tunnel vault detection mechanism (40), and the tunnel side wall detection mechanism (20) is used for detecting a tunnel side wall; the tunnel haunch detection mechanism (30) is used for detecting a tunnel haunch; the tunnel vault detection mechanism (40) is used for detecting a tunnel vault. The tunnel side wall detection mechanism, the tunnel haunch detection mechanism and the tunnel vault detection mechanism in the tunnel lining detection device can stretch out and draw back and rotate, can cover the full sections of different detection lines, have the advantages of being convenient and light to control, convenient to load and operate, free of dead angles in view and the like, and improve the detection efficiency by several times or more compared with similar products.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a tunnel lining detection device. Background technique [0002] Tunnel lining inspection in railway operation is one of the important preventive measures to ensure traffic safety. At present, the mainstream technology of non-destructive inspection of tunnel lining in China is to use geological radar for inspection. Ground radar detection mainly includes manual and vehicle-mounted detection methods. The manual operation method consumes a lot of manpower and the operation method is simple. my country has developed a tunnel status inspection vehicle for ordinary speed railways. Compared with the traditional detection method, the detection automation has been significantly improved. After the ground radar is stretched to the target position by using five mechanical arms, it will detect with the vehicle running, and realize the detection of the tunnel lining state of the exi...
