Integrated detection truck for road tunnel defects

The invention discloses an integrated detection truck for road tunnel defects. The integrated detection truck comprises a truck head and a carriage connected to the rear of the truck head. The carriage is further provided with an infrared camera detecting mechanism, a radar-linear-array camera detecting mechanism, a cantilever crane assembly, a lighting lamp, a main control chamber and a generator. The infrared camera detecting mechanism is installed at the front end of the carriage, the main control chamber is arranged at the rear end of the carriage, the cantilever crane assembly is fixed in the carriage and located between the infrared camera detecting mechanism and the main control chamber, the radar-linear-array camera detecting mechanism is installed on the cantilever crane assembly, the lighting lamp is installed on the radar-linear-array camera detecting mechanism, and the generator is arranged on one side of the cantilever crane assembly. A linear array camera detection device, an infrared camera detection device and a radar detection device are integrated, and the three defects including lining crack, water leakage and cavities of a tunnel are detected at the same time. The integrated detection truck has the advantages of being high in detecting efficiency, free of contact, high in safety and the like, and has very good application prospects in the road tunnel defect detection aspect.
