Description

Pipeline welding positioning auxiliary device Technical Field The utility model relates to the technical field of pipeline welding, in particular to a pipeline welding positioning auxiliary device. Background The steel pipes are generally connected to long-distance pipes by using a connecting device such as a welding device and a flange, and the pipes are required to be welded after a plurality of pipe sections are placed at proper positions. In order to avoid the phenomena of dislocation and the like during welding, the phenomena of stress transformation and the like after welding, auxiliary support is needed for the welded pipeline. The existing pipeline welding positioning auxiliary device can achieve the effect of pipeline positioning auxiliary, but cannot drive a pipeline to rotate, and when the pipeline is welded, a worker needs to adjust the body position at intervals to weld the joint seam, so that the working efficiency is greatly affected, and the pipeline welding positioning auxiliary device is inconvenient for the worker to use. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a pipeline welding positioning auxiliary device, which aims to solve the problems that the prior pipeline welding positioning auxiliary device in the background art can achieve the effect of pipeline positioning auxiliary, but can not drive a pipeline to rotate, and a worker needs to adjust the body position at intervals to weld a splicing seam during pipeline welding, so that the working efficiency is greatly influenced, and the use of the worker is inconvenient. In order to achieve the above purpose, the pipeline welding positioning auxiliary device comprises a base, wherein the middle side of the top of the base is fixedly connected with a mounting seat, the inner side of the mounting seat is rotationally connected with a rotating shaft, the left end of the rotating shaft is fixedly connected with a first transmission gear, the right end of the rotating shaft is fixedly connected with a second transmission gear, the two sides of the top of the base are fixedly connected with a connecting seat, the top of the connecting seat is fixedly connected with a mounting sleeve, the middle side of the inner wall of the mounting sleeve is provided with a mounting groove, the inside of the mounting groove is rotationally connected with a rolling shaft, one side of the rotating shaft away from the mounting groove is rotationally connected with a positioning sleeve, one end surface of the positioning sleeve, close to the mounting seat, is fixedly connected with a transmission gear ring, one side of the positioning sleeve, away from the mounting seat, is fixedly connected with a connecting rod, the connecting rod is fixedly connected with an auxiliary ring, the inner wall of the positioning sleeve is fixedly connected with an electric push rod, and the extending end of the electric push rod is fixedly connected with a positioning plate.
