Dedicated pipeline welding device

Abstract

The invention discloses a dedicated pipeline welding device. The device comprises a guide device, a welding gun, a clamping pipe sleeve, a straight segment, a flaring segment and a nut; the guide device comprises a disc, rollers fixedly arranged on the inner wall of the disc and two baffles arranged on the two ends of the disc; at least three rollers are evenly distributed, one of the two bafflesis provided with a gap, a connecting plate fixedly connected with the disc is arranged under the gap, the welding gun is fixedly arranged on the connecting plate, the welding gun comprises a cable, and the cable penetrates the gap and is wound on the disc, each baffle is divided into two parts, a locking device is fixedly arranged on the outer wall of each baffle, and two parts of each baffle areconnected through a locking clamp. Pipeline opening alignment and welding are integrated, unstability caused by the manual factor can be reduced, and welding quality stability is ensured.

Description

technical field [0001] The invention relates to a special pipe welding equipment. Background technique [0002] In the construction of pipeline engineering, when welding two sections of pipelines into one section, manual welding is usually used at present. During pipeline piping and welding, it is necessary to ensure that the nozzles of the two pipes are concentric / aligned and the gap between the nozzles meets the parameter requirements of the welding procedure, so as to avoid quality problems such as impenetrable welds and excessive deviation of misalignment. However, in conventional pipeline piping and welding, construction personnel mainly rely on construction experience to realize the combination of two pipe cores through visual inspection and ruler measurement, and perform positioning welding. In this way, the nozzle gap and construction quality are greatly affected by human factors, so the alignment error of the pipeline is relatively large, which in turn makes the qu...

AI Technical Summary

Problems solved by technology

In this way, the nozzle gap and construction quality are greatly affected by human factors, so the pipe alignment error is relatively large, which in turn makes the quality of its positioning welding very unstable

In addition, due to manual welding, the distance between the welding torch and the welding port is difficult to control, which may lead to unstable welding quality; for novices, it is particularly difficult to control the distance between the welding torch and the welding port

During the welding process, the welding torch needs to move around the axis of the pipe, and the cable connected to the welding torch is easy to wind around the pipe and pull the welding torch, which makes the welding operation more inconvenient
