Welding mechanism of pipeline

Abstract

The invention discloses a welding mechanism of a pipeline for carrying out welding and cutting on large-scale pipelines, which is characterized by comprising a basic support mechanism, a track circle,a sliding mechanism and a welding and cutting mechanism, wherein the basic support mechanism is provided with a basic support circle which is connected with an arc-shaped rotary arm; the arc-shaped rotary arm is provided with a loose pin installation jig; the basic support mechanism is also provided with bolts to connect the track circle; the sliding mechanism is connected to the track circle ina sheathing manner; the sliding mechanism is provided with a gear which is meshed with a transmission gear; and the sliding mechanism is installed with the welding and cutting mechanism. The inventionhas the following obvious effects: satisfying the welding and cutting requirements of large-scale pipelines with different sizes, controlling the work of the welding and cutting devices through a computer, adapting to the construction requirements in severe environment, replacing manual operation and ensuring the stability and high efficiency of construction quality.

Description

technical field [0001] The invention belongs to the technical field of pipeline welding and cutting, in particular to a pipeline welding mechanism for welding and cutting large pipelines. Background technique [0002] As people's demand for energy and water increases, the pipelines that transmit oil, natural gas, and water energy resources are becoming more and more large-scale. The large-scale pipeline network is composed of several large-diameter steel pipes welded in sequence. , The passage of high-pressure and strong fluids requires very high welding technology between steel pipes, requiring straight weld seams and thin weld scars. [0003] At the same time, in the transformation of the old pipe network, there is also a lack of special cutting equipment, and only manual welding and manual cutting are used, which has high requirements for the workers' operating skills and operation stability, which also increases the construction cost. difficulty and intensity.

Problems solved by technology

[0003] At the same time, in the transformation of the old pipe network, there is also a lack of special cutting equipment, and only manual welding and manual cutting are used, which has high requirements for the workers' operating skills and operation stability, which also increases the construction cost. difficulty and intensity

[0004] The disadvantages of the existing technology are: there is no special large-scale pipeline welding device, only manual welding and manual cutting can be used, the difficulty and intensity of construction are high, the construction speed is full, and the welding quality is unstable
