Large barrel automatic welding detection fixing device

Abstract

The invention discloses a large barrel automatic welding detection fixing device comprising a supporting platform. The two sides of the supporting platform are each fixedly connected with a row of supporting stand columns. Rotation rolling wheels are arranged on each row of supporting stand columns correspondingly. A sliding base transversely sliding is arranged on the supporting platform. A control module is arranged on the sliding base. A telescopic slide shaft sliding in a telescopic manner is arranged on the control module. The telescopic slide shaft is provided with a butt joint connection tip. Multiple control rotating shafts are connected to the butt joint connection tip in series. A sliding rotation sleeve is arranged on each control rotating shaft. Multiple swinging supporting pull rods are arranged on each rotation sleeve. By means of sliding of the telescopic slide shaft, the control rotating shafts can be stretched into a barrel tank. By means of the supporting pull rods, awelding barrel can be welded, the aim of supporting can be achieved, and the problem of precision deviation caused by a traditional supporting manner is prevented.

[0002] With the continuous improvement of the industrial development level, the continuous improvement of the industrial manufacturing level has been further promoted. In the current industrial production, the transmission pipeline is one of the common pipelines, so that oil or water resources can be transported through the pipeline. Among them In today's pipelines, steel pipes are a common pipeline. During the processing of large-scale pipelines, multi-section pipelines need to be welded to achieve long-distance transportation through pipelines. In the process of welding pipelines, due to the If the diameter is too large, it will cause the deformation of the pipe, so in the process of welding the two pipes, there will be abnormal welding. In the process of supporting the pipe, most of them are carried out through the support frame. Support, so as to ensure its stability and prevent its deformation. Although the supporting frame can play a supporting role, there are still the following problems:

[0003] Because it is supported by the support frame, there will be a positioning deviation during the support process, so there will be a certain butt joint deviation of the pipeline, which will seriously affect the welding accuracy. Uniformity leading to leakage problems
