Abstract

The invention discloses a tunnel lining detection device. The tunnel lining detection device comprises a foundation platform (10), a tunnel side wall detection mechanism (20), a tunnel waist detection mechanism (30) and a tunnel vault detection mechanism (40). , the tunnel side wall detection mechanism (20) is used to detect the tunnel side wall; the tunnel vault detection mechanism (30) is used to detect the tunnel vault; the tunnel vault detection mechanism (40) is used to detect the tunnel vault. The tunnel side wall detection mechanism, tunnel arch waist detection mechanism and tunnel vault detection mechanism in the tunnel lining detection device can all be telescopic and rotated, and can cover the full cross-section of different survey lines. It has the advantages of no dead angle, etc., and the detection efficiency is several times higher than that of 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] The detection of tunnel lining in railway operation is one of the important preventive measures to ensure driving safety. At present, the mainstream technology of non-destructive testing of tunnel lining in China is to use ground-based radar for detection. Geological radar detection mainly includes manual, vehicle-mounted and other detection methods. The manual operation method consumes a lot of manpower and the operation method is simple. my country has developed a tunnel condition inspection vehicle for ordinary speed railways. Compared with the traditional detection methods, the detection automation has been significantly improved. After the five manipulator arms are used to carry the geological radar to the target position, the detection is carried out with the operation of the vehicle, which realizes t...
