The utility model relates to the technical field of
vehicle detection, in particular to a trench for detecting an automobile
chassis, which comprises a detection platform, a trench body, an air cylinder, a guide rail, a sliding plate, a telescopic support
assembly, an appearance detection camera and a support dismounting mechanism, two first guide rails are transversely arranged at the bottom of the trench body, an air cylinder is installed between the two first guide rails, a
piston rod of the air cylinder is connected with a sliding plate, and the sliding plate is slidably connected with the first guide rails. Compared with the prior art, the trench for detecting the automobile
chassis is designed, the appearance detection camera is fixed on the telescopic bracket
assembly, the telescopic bracket
assembly can be taken down through the bracket dismounting mechanism, and the position of the telescopic bracket can be adjusted according to the detection position requirements of different automobile
chassis, so that the appearance of the automobile chassis can be detected after the telescopic bracket assembly is mounted. And the position of the appearance detection camera in the trench is adjusted, so that the situation that a worker enters the trench to carry out secondary detection is reduced.
