Description

Bridge steelframe welding set Technical Field The application relates to the technical field of welding, in particular to a bridge steel frame welding device. Background In bridge steel construction, a large number of longitudinal or transverse stiffeners are welded to the web of an H-beam, box beam or the like to enhance its local stability, the connection between the stiffener and the web is typically a continuous fillet weld, which, although relatively short in length (typically tens of centimeters to several meters), is numerous and has high requirements for weld quality and consistency. At present, when the stiffening ribs are welded on a construction site, manual welding is generally adopted, a welder completely depends on experience and a handheld welding gun to operate, and the mode has the remarkable defects that the working angle (the included angle between the welding gun and a web) and the walking angle of the welding gun are completely maintained by the arm posture of the welder, and the welding gun is extremely easy to shake or angle deviation due to fatigue in the welding process, so that uneven welding seam penetration and rough appearance are caused, and the welding quality is influenced. Disclosure of utility model The application provides a bridge steel frame welding device, which aims to solve the problem that shaking or angle deviation is easily generated due to fatigue in the welding process. The application provides a bridge steel frame welding device which adopts the following technical scheme: The utility model provides a bridge steelframe welding set, includes the base, a plurality of switchable permanent magnetism adsorption blocks that are used for adsorbing to fix on steel structure web surface are installed to the base bottom, angle adjustment mechanism is installed at the base top, angle adjustment mechanism's angle regulation output is fixed with linear slide rail, slidable mounting has the slide on the linear slide rail, the fine setting mechanism is installed to one side that angle adjustment mechanism was kept away from to the slide, install welding mechanism on fine setting mechanism's the regulation end, fine setting mechanism is including fixing the groove seat on the slide, the inside sliding connection of groove seat has the lifter that is used for the location, welding mechanism includes the extension frame, extension frame and lifter fixed connection.
