Problems solved by technology

Crane or manual flip, because the tower is heavy and there is no limit device, so the positioning is not accurate, the best welding angle requirements are not met, the weld quality is unstable, and there are many quality problems such as uneven welds, missing welds, air holes, slag inclusions, etc. The problem, if serious, may lead to insufficient strength of the tower and collapse of the tower

Abstract

A welding device for a base of an iron tower in a power transmission line comprises an anti-tipping rack, a turnover mechanism, a rotating mechanism and a quick positioning and clamping workpiece platform, wherein the turnover mechanism enables the base to overturn by 110 degrees, and is fixed on the anti-tipping rack through a bearing support; the rotating mechanism enables a working platform to rotate by 360 degrees leftward or rightward, and is fixed on a turnover shaft; the quick positioning and clamping workpiece platform is fixed on a rotating shaft of the rotating mechanism; the working platform rotates along with the rotation of the rotating shaft. Through the adoption of the welding device, the quick clamping and the universal positioning of the base can be realized, the positioning is accurate and convenient, sufficient strength, anti-tipping capacity and anti-impacting capacity are provided, the stable operation of the device in the processes of loading, overturning and rotating is ensured, and the welding device is durable in long time use, is simple to operate and reduces labor intensity.

Description

technical field [0001] The invention relates to the technical field of electric power tower production, in particular to a transmission line iron tower base welding device, which controls the universal rotation of the tower base, quickly realizes the clamping of the tower base, quickly realizes the precise positioning of the welding station, and improves the welding efficiency of the tower base and welding quality. Background technique [0002] The tower base of the electric power tower is generally made of tailor-welded 6 to 10 steel plates, and there are as many as a dozen welds on the tower base. Due to the large force on the tower base, in order to ensure the strength, the weld seams of the tower base are designed to be welded above the second level. The size of the weld seam is large, and the welding time is long; and a tower weighs 100 to 1000 kg, so it is necessary to use a crane to realize the flip positioning of the tower during welding to meet the welding requireme...
