Description

Hanging rail for tunnel inspection and inspection device Technical Field The invention relates to the technical field of tunnel inspection, in particular to a hanging rail for tunnel inspection and an inspection device. Background The conventional hanging rail for tunnel inspection generally adopts steel rails, the weight of the steel rails is heavy, the laying and the installation are inconvenient, the hanging rail adopts hollow aluminum rails, the hollow aluminum rails are easy to deform due to expansion caused by heat and contraction caused by cold due to weather influence in the use process, the assembly and the butt joint are inconvenient, the dynamic change scene is difficult to adapt, the whole weight of the inspection mechanism is heavy, and the rail deformation is easy to occur in the operation process.
