Auxiliary device for pipeline and joint welding

Abstract

The invention discloses an auxiliary device for pipeline and joint welding. The auxiliary device comprises an operation table, wherein the center of the operation table is in rotatably connected witha butt-joint table; a through hole is formed in the center of the butt-joint table; a support frame is arranged above the through hole; the support frame is used for supporting a joint; the outer sideof the through hole is equipped with a lifting assembly; the support frame is movably connected onto the lifting assembly; the butt-joint table is movably connected with three tube support assemblieswhich are used for clamping a pipeline; the operation table is equipped with a drive assembly; and the drive assembly links and drives the tube support assemblies to move towards the center of the operation table for connecting the pipeline to a joint. The auxiliary device only needs single-person operation, greatly reduces labor power, and is simple and convenient in operation; and the support frame and the tube support assemblies separately control the joint and the pipeline, so that the joint and the pipeline are prevented from shaking, and therefore, welding precision is improved, and construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline installation, and in particular relates to an auxiliary device for welding between pipelines and joints. Background technique [0002] In the pipeline system, the joint plays the role of the connection between the pipe and the pipe, as well as the convenience of pipeline construction, maintenance and disassembly; welding the joint at the end of the pipeline can extend the pipeline from multiple angles, so as to achieve the required Installation effect and installation length. [0003] When welding pipes and joints, one person needs to keep the pipes still, another person connects the joints to the pipes and joints, and at the same time ensures that the joints will not shake on the pipes, and the third person welds the pipes and joints; when three sets of pipes and joints are required When the joint is welded, the operation is more cumbersome and wastes manpower, and the artificial control of the...
