Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of crane semi-girder cover plate welding Anti-deformation tooling, comprise 16 firm bankings 1 be arranged in order according to constant spacing, firm banking 1 is combined by connecting rod 11 and the base support 12 be welded on below connecting rod 11 two ends; Above connecting rod 11, one end is installed with fixing backer 2, and the other end is provided with the mobile backer 3 parallel with fixing backer 2, moving direction be along connecting rod 11 direction near or away from fixing backer 2.
Described fixing backer 2 rotatably compresses block 5 by 4 rectangular steel pipes 4,16 and combines, and the semi-girder cover plate straight flange of 10 meters long can be made to carry out reversible deformation operation simultaneously; Rotatably compress block 5 side to be fixedly mounted on inside rectangular steel pipe 4, and base is fixedly mounted on above connecting rod 11.
