Multi-edge steel pipe flange inner and outer girth welding equipment

Abstract

The invention provides multi-edge steel pipe flange inner and outer girth welding equipment. The multi-edge steel pipe flange inner and outer girth welding equipment comprises an electric chain type overturning frame, tracking welding equipment and cross-shaped sliding tables with sliding table motors. The cross-shaped sliding tables are arranged on the left side of the overturning frame, and first sliding blocks installed on the cross-shaped sliding tables are fixedly connected with connecting rods. The tracking welding equipment is fixed to one end of each connecting rod, and the other ends of the connecting rods are fixed to the first sliding blocks of the cross-shaped sliding tables. Each piece pf tracking welding equipment comprises a sliding rail vertically installed at the end of the corresponding connecting rod, a multi-edge pipe tracking wheel and an automatic welding gun installed on a welding gun oscillator, second sliding blocks are arranged on the sliding rails, the welding gun oscillators are fixedly connected to the second sliding blocks, the multi-edge pipe tracking wheels are fixedly connected with the second sliding blocks through roller frames, and the same plane where the automatic welding guns and the multi-edge pipe tracking wheels are located is perpendicular to the vertical face of the overturning frame. According to the multi-edge steel pipe flange inner and outer girth welding equipment, the girth welding quality is high, the speed is high, and the requirement for the flange positioning pre-welding quality is not high; and the equipment is low in cost and stable and reliable in performance.

Description

technical field [0001] The invention relates to the technical field of automatic welding equipment, in particular to an equipment for welding the inner and outer ring seams of multi-edge steel pipe flanges, which is used for welding the inner and outer ring seams of connecting flanges of electric power or communication steel pipe towers. Background technique [0002] The steel pipe tower is a support structure for overhead transmission lines to support conductors and lightning protection lines, and the tower body is connected by flanges or intersecting connections. When welding flanges in the process of making electric steel pipe towers, welders generally rotate and weld manually, which is time-consuming and labor-intensive and poses safety hazards. The announcement number is CN210365705U-an electric chain-type overturning frame for turning over the tower pole, which is used for turning over the multi-edge pipe, and the inner and outer seams of the flange are manually welded...
