Displacement Tooling for Welding Longitudinal Seam of Steel Pipe Rod for Power Transmission and Transformation

Abstract

The invention provides a welding deflection tool for a cross arm longitudinal seam of a power transmission and transformation steel pipe. The welding deflection tool comprises a fixing mechanism. The fixing mechanism comprises a movable support seat and a fixed support seat. The fixed support seat comprises a mounting seat and an overturning clamp, the overturning clamp is mounted on the top of the mounting seat, the overturning clamp comprises a rotary shaft and a transverse guide rod, the transverse guide rod is slidably provided with two pincers, the transverse guide rod is provided with a chute, a pulley is mounted in the chute, the pulley is connected to a steel rope, and the steel rope is connected the two pincers. The movable support seat comprises a base and a lifting mechanism. The lifting mechanism comprises a lifting lead screw and a support plate; and a worm gear and a worm are arranged in the base, one end of the lifting lead screw extending into the base is meshed with the worm gear, and the support plate is also provided with another overturning clamp. The other end of a rotary shaft of one of the overturning clamps is provided with an overturning handle and a positioning pin; and the fixed support seat or the support plate is provided with a positioning hole matched with the positioning pin. The welding deflection tool for a cross arm longitudinal seam of a power transmission and transformation steel pipe effectively improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of processing equipment for steel pipe poles for power transmission and transformation, in particular to a displacement tool for welding longitudinal seams of steel pipe poles for power transmission and transformation. Background technique [0002] The straight seam welding of the cross-arm of the steel pipe pole in the prior art basically all adopts the method of manual welding, and the general manufacturer adopts simple tooling to position the cross-arm and then automatically welds. For example, the Chinese patent with the patent number CN201520376934.5 discloses a welding device for the butt joint longitudinal seam of the cross-arm box body in the steel pipe pole of the transmission line, including the power drag line support, the cross-arm fixing device, the mobile lifting bracket, the welding machine track machine Welding device, the power towing line bracket is set independently, the oil scraping power...

Problems solved by technology

[0003] However, the simple positioning tool of the above structure requires the help of lifting equipment when clamping the workpiece, and the welding needs to be stopped to complete, and when the weld seam welding on one side of the cross arm is completed, the workpiece needs to be unloaded, and then flipped 180 degrees to carry out the other side. Welding, the operation is time-consuming and cannot be operated continuously, which seriously affects the production efficiency
