Abstract

The invention provides a steel plate positioning system, welding equipment and a welding method for U rib plate unit welding. The steel plate positioning system comprises a steel plate transverse centering device, a steel plate transverse clamping device and a steel plate longitudinal clamping device. The steel plate transverse centering device is used for transverse centering and positioning of a steel plate, the steel plate transverse clamping device is used for transverse positioning and clamping of the steel plate, the steel plate longitudinal clamping device is used for clamping the steel plate in the longitudinal direction of the steel plate, and the steel plate transverse clamping device is arranged on the two sides of one end of the steel plate. The steel plate longitudinal clamping device is arranged at the other longitudinal end of the steel plate, and the steel plate transverse centering device is arranged on the two transverse sides of the steel plate. According to the steel plate positioning system, the welding equipment and the welding method, on one hand, transverse centering and positioning can be effectively carried out on welding of the U-shaped rib plate units with the steel plates moving, on the other hand, effective transverse positioning and clamping can be carried out on welding of the U-shaped rib plate units with the steel plates moving, and moreover, longitudinal clamping is carried out on welding of the U-shaped rib plate units with the steel plates moving.

Description

technical field [0001] The invention relates to welding technology, in particular to a steel plate positioning system, welding equipment and method for U-rib unit welding. Background technique [0002] Today's large bridges use steel box girder structures. Steel box girders are mainly used to provide support and avoid bridge deformation. Steel box girders are generally connected by all-welded roof, bottom, and closed ribs, and the bottom plate and closed ribs form a U-rib unit structure. At present, in practical applications, when the steel box girder bottom plate (steel plate) is welded to the steel box girder closed rib (U rib), the welding method of fixing the bottom plate is mostly used. In this welding method, the positioning of the steel plate is simple, and most of them are directly on the steel plate. Secure it on both sides. This fixed structure cannot be used for a mobile welding platform, and it cannot perform effective lateral centering and positioning for the ...
