A steel plate receiving and welding platform for steel towers

Abstract

This invention relates to a steel plate receiving and welding platform for steel towers, which can be configured in several flat positions. Its features include a platform frame, a sliding baffle, a tilting and lifting module, a tilting and leveling module, and a drive module. The steel plate is placed on the welding platform, and a lifting hydraulic cylinder drives the lifting plate to rotate around a hinged lug, lifting the steel plate from a horizontal state to a vertical state, where it is tightly adhered to the sliding baffle. Then, a drive motor moves the sliding baffle from one end of the base to the other. A leveling hydraulic cylinder drives the leveling plate to rotate around the hinged lug, tightly adhering to the back of the steel plate. The sliding baffle then moves to the other end, and a leveling hydraulic cylinder lowers it, turning the steel plate over. This device greatly improves the turning efficiency of ultra-large and ultra-thick steel plates.
