Steel box girder U-shaped reinforcing rib welding production line

Abstract

The application discloses a kind of steel box girder U type reinforcing rib welding production line, belong to bridge body steel structure processing technical field, the production line includes installation in the inner cavity of concrete foundation turnover jig: the front side and rear side of the turnover jig bottom are rotationally connected with concrete foundation by triangular support shaft seat, the inner cavity bottom of concrete foundation is fixedly installed with three turnover hydraulic cylinders on both sides.The cooperation of hoisting frame, jacking assembly and alignment assembly is used to lift the box girder plate, push it to the specified position on the top of the turnover jig, then the cooperation of fixed clamping plate, advancing assembly and anti-skid assembly is used to limit and block the two sides of the box girder plate, finally, the welding posture of the box girder plate is adjusted under the cooperation of the turnover jig and the turnover hydraulic cylinder, and the box girder plate and the U-shaped reinforcing rib are welded and fixed by the multi-wire submerged arc welding machine, which can automatically correct the position of the box girder plate, automatically find the blocking and clamping, and ensure the stability of welding in different postures.
