Abstract

The invention relates to the technical field of steel structure installation, in particular to a preheating welding device for steel structure installation construction. A portal frame is fixed abovea base, a PLC control cabinet is arranged above the base and at one side of the portal frame, two second telescopic clamping assemblies are arranged at one end of the lower part of the portal frame, and a longitudinal and transverse adjusting mechanism connected with the second telescopic clamping assemblies is fixed to a position, corresponding to the second telescopic clamping assemblies, abovethe portal frame. The preheating welding device is novel in design, simple in structure and easy and convenient to operate, two steel structures to be welded can be adjusted, butt joint preheating ofdifferent angles and positions is met, manual carrying is not needed, the labor intensity and potential safety hazards of manual carrying are reduced, the preheating efficiency is effectively improved, direct welding can be achieved after preheating, moving is not needed, heat losses are reduced, the preheating uniformity is guaranteed, the crack resistance of a welding line is improved, and the project progress is shortened.

Description

technical field [0001] The invention relates to the technical field of steel structure installation, in particular to a preheating welding device for steel structure installation and construction. Background technique [0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. It is mainly composed of beam steel, steel columns, steel trusses and other components made of section steel and steel plates. Some steel structures need to be welded during installation. However, in order to improve the crack resistance of the weld, the welding stress and temperature difference are usually reduced by preheating the welding end. [0003] But the self-weight of the steel structure is relatively large, there is no specific auxiliary tooling, and the steel structure is usually raised by the workers through bricks, which is very inconvenient, labor-intensive, and inefficient. Therefore, those skilled in the art provide a steel st...
