Lifting device for steel structure building construction

The utility model belongs to the technical field of hoisting devices, and particularly relates to a hoisting device for steel structure building construction, which comprises a base, a rotating plate and a movable plate, and a mounting groove is formed in the top wall of the base; the rotating plate is rotatably arranged on the bottom wall of an inner cavity of the mounting groove, second servo motors are symmetrically arranged on the top wall of the rotating plate, screw rods are arranged on output shafts of the two second servo motors, and connecting plates are arranged on the two screw rods in a threaded connection and penetrating mode. According to the lifting device, when a lifted object needs to be moved in the horizontal direction, the two second servo motors are started at the same time to drive the screw rod to rotate, so that the movable plate moves left and right, and then the lifted object can move in the horizontal direction; when the hung object needs to be rotated in the horizontal direction, t
