Description

Technical Field

[0001] This utility model belongs to the field of steel pipe welding technology, and specifically relates to a steel pipe alignment welding device. Background Technology

[0002] Steel pipes are a common type of pipe material, used in the transportation of liquids and gases due to their unique corrosion resistance. In practical applications, steel pipes need to be cut and welded due to varying lengths required. Small batches can be welded manually, but manual welding is inefficient and uneconomical for large batches of steel pipes of different specifications. Steel pipes that are aligned for welding are mostly of the same specification. When performing aligned welding, the steel pipes need to be screened according to their different diameters first.

[0003] In existing related technologies, when welding steel pipes, it is necessary to align the steel pipes to be welded with the gap before welding. However, it is not possible to effectively adjust the alignment of the steel pipes during welding. Therefore, there is an urgent need to design a steel pipe alignment welding device to solve these problems. Utility Model Content

[0014] This utility model discloses a steel pipe alignment and welding device. Through a movable docking mechanism, a first motor drives a first lead screw to rotate, causing a first movable platform, a support platform, and a telescopic lower platform to move relative to or towards each other. This movement can be adjusted according to the length of the steel pipe. An electric telescopic rod is activated to push the telescopic lower platform and a scale within the support platform, simultaneously aligning the steel pipe with the telescopic lower platform using the scale.
