Description

Steel member welding set based on central location Technical Field The utility model relates to a positioning steel member welding device, in particular to a steel member welding device based on center positioning. Background In the technical field of building construction, various steel structural members such as H-shaped steel, cross-shaped steel, angle steel and the like are generally used, and the steel structural members are light in weight, convenient to transport and have certain structural strength, so that the steel structural members are widely applied to the construction of factories and venues; According to different design demands, the types and the shapes of the used steel structures are different, in actual building design, the length of the H-shaped steel is required to be prolonged according to specific demands of a factory building and a venue, so that the H-shaped steel with the same specification is required to be welded together, the ends of the two H-shaped steels are required to be mutually aligned in the welding process, the welding effect can be ensured, if the H-shaped steels are welded under the condition that the H-shaped steels are not aligned, the phenomenon of infirm welding exists, and certain potential safety hazards exist in the factory building and the venue, so that the H-shaped steel components are required to be positioned in the welding process. The mode of carrying out central location with the steel component at present mainly has modes such as mechanical clamp, hydraulic pressure anchor clamps or flexible push pedal to go on, can realize the central location to the steel component, be provided with the anchor clamps on central location structure and fix the steel structure, the anchor clamps adopt single-point or two-point clamping generally, can only fix two faces of steel component, the steel component is liable to take place displacement or deflection in welding process, and need splice the welding face of two steel components before the welding work, when carrying out multiaspect welding to the steel component simultaneously, also need turn over the steel component, because the steel component is self heavier, need be with the help of special roll-over stand or many people collaborative operation, can't satisfy high-efficient welding's demand. Disclosure of utility model The utility model aims to provide a steel member welding device based on central positioning, which is used for solving the problems that the clamp provided in the background technology adopts single-point or double-point clamping, only one to two surfaces of a steel member can be fixed, the steel member is easy to displace or deflect in the welding process, the welding surfaces of two steel members are required to be spliced before welding work, and meanwhile, when the steel member is subjected to multi-surface welding, the steel member is required to be turned over, and because the steel member is heavy, the requirement of high-efficiency welding cannot be met by means of a special turning frame or multi-person cooperative operation.
