The invention relates to the technical field of forklift robots, in particular to a forklift robot space scanning device. The device comprises a forklift body, sliding columns are symmetrically mounted on the position, close to the front end, of the upper surface of the forklift body, sides, opposite to each other, of the two sliding columns are provided with sliding grooves, hydraulic cylinders are arranged on the bottoms of the sliding grooves, sliding rods are arranged on the tops of the two hydraulic cylinders, the position, close to the rear end, of the lower surface of a sheltering plateis connected with the forklift body through a supporting column, a forklift plate is arranged on the front end faces of the sliding rods, according to the forklift robot space scanning device, the two hydraulic cylinders are arranged in the sliding columns in a matched manner, the sliding rod can conveniently ascend and descend, under the effect of a first rubber block and a second rubber block,rotation is more stable, the phenomenon that due to flexible rotation in a user, use of a space scanner is affected can be avoided, the space scanner is rotatably connected with a supporting plate, under the effect of a fastening bolt, the position can be fastened, a rotating shaft column rotates left and right on a rotating shaft base, the space scanner vertically rotates on the supporting plate,and the whole space scanner can carry out comprehensive scanning.
