The utility model discloses a safety lifting device for building construction, which comprises a base, a movable plate, a support leg, an electric screw rod and a top plate, one side of the base is connected with the movable plate, the movable plate and the base form a rotating structure, the upper surface of the movable plate is connected with the support leg in a penetrating manner, and the electric screw rod is vertically arranged on the upper surface of the base. According to the safe lifting device for building construction, a push rod pushes a piston to extrude oil in a working cavity, and when maintenance liquid in an oil guide pipe between an oil tank and the working cavity is extruded, the maintenance liquid is sprayed out from a spray head to an electric screw rod to maintain threads on the outer wall of the electric screw rod, so that the electric screw rod is prevented from being abraded after being used for a long time, and the service life of the electric screw rod is prolonged. And when the pus
