A steel pipe pole cross arm welding tool

Abstract

The present invention proposes a steel pipe rod cross-arm welding tool, including a workbench, a left sliding platform is arranged on the left side of the workbench, and a first sliding platform for clamping and positioning one end of the steel pipe rod cross-arm A positioning mechanism, the right side of the workbench is provided with a right sliding platform, the first positioning mechanism for clamping and positioning the other end of the steel pipe rod cross arm is slidably arranged on the right sliding platform, and the middle part of the workbench is fixedly provided with a bearing Platform, the carrying platform is provided with a third positioning mechanism for positioning the steel pipe rod cross-arm bottom plate. The welding tooling of the present invention does not need manual marking alignment, and through the combined use of the first positioning mechanism, the second positioning mechanism and the third positioning mechanism, the welding of two vertical plates and the top plate, and the welding of the bottom plate and the two vertical plates can be continuously performed. Welding of the vertical plate, thereby improving the production efficiency of steel pipe rod cross-arm welding.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a steel pipe rod cross-arm welding equipment. Background technique [0002] The cross arm of the electric steel pipe pole is the supporting structure for erecting the transmission line. It generally adopts a box structure, that is, four steel plates are used, which are two vertical plates, a bottom plate and a top plate, which are welded together to form a box. Wherein, the two vertical plates are parallel to each other, the upper side of the vertical plate is welded perpendicularly to the top plate, and the lower side of the vertical plate is welded to the bottom plate, and the bottom plate and the top plate form a certain angle. Such an electric steel pipe rod cross-arm structure is installed on the iron tower, which not only ensures the strength, but also ensures the aesthetics.

Problems solved by technology

[0003] Compared with the steel pipe rod cross-arm welding in the prior art, the method of manual welding is basically adopted. Usually, one end of the two vertical plates is fixed vertically and parallelly with a fixed jig, and then the top plate is placed on the two vertical plates. At the bottom of the vertical plate, manually adjust the welding seam position between the top plate and the vertical plate, after pre-welding, initially position, then draw a line on the top plate, and make the other end of the vertical plate flush with the line on the top plate, after pre-welding Initial positioning, after the initial welding and positioning of the two ends of the vertical plate and the top plate, the refined welding of the vertical plate and the top plate is carried out. When welding the vertical plate and the bottom plate, it is necessary to turn 180 degrees to weld the bottom plate and the vertical plate. bad

Therefore, the above-mentioned manual welding has the problems of time-consuming, low positioning accuracy and low production efficiency.
