Shield tunnel laser three-dimensional mobile scanning assembly

The utility model belongs to the technical field of rail traffic detection equipment, and particularly relates to a shield tunnel laser three-dimensional mobile scanning assembly which comprises two rails, two sets of rollers are arranged at the tops of the two rails, rotating shafts are fixedly arranged on the sides, close to each other, of the two sets of rollers, and a same mounting box is movably arranged between the two sets of rotating shafts. When the scanning angle and the scanning direction need to be adjusted, the driving motor and the push rod motor are started, the driving motor drives the disc through the output shaft, the disc drives the vertical plate and the guide plate, the guide plate drives the scanner to rotate, the scanning direction is adjusted, the output end of the push rod motor extrudes the guide plate, and the scanning angle and the scanning direction are adjusted. The guide plate drives the scanner, the scanning angle can be adjusted, the scanning direction and the scanning angle c
