Ship steel member welding platform with self-positioning function

The invention discloses a ship steel member welding platform with a self-positioning function, and relates to the field of welding platforms, the ship steel member welding platform comprises a base and a servo motor fixedly mounted at the rear end of the base, a first rack is mounted at the output end of the servo motor through gear engagement, and two-way threaded rods are mounted on the left side and the right side of the first rack through gear engagement. According to the ship steel component welding platform with the self-positioning function, when the height of the lifting welding plate is adjusted, whether anti-skid positioning is carried out or not can be selectively selected, when the device needs to be prevented from deviating and slipping, an electric telescopic rod is started, so that a contact plate downwards applies pressure to the ground, and the ship steel component welding platform can be tightly attached to the ground in cooperation with arrangement of an anti-skid pad; and meanwhile, the up
