Pipeline welding opening supporting equipment

Abstract

The invention discloses pipeline welding opening supporting equipment, and relates to the technical field of pipeline welding. The pipeline welding opening supporting equipment comprises a containing bottom plate, the center of the top of the containing bottom plate is connected with the center of the bottom of a supporting arc plate through an elastic telescopic supporting column, and the bottoms of the two sides of the supporting arc plate are hinged to one ends of two hinged transmission rods correspondingly. According to the pipeline welding opening supporting equipment, by arranging the supporting arc plate, a supporting function can be achieved on welding end openings of two steel pipes, meanwhile, the supporting arc plate can descend under the action of the steel pipes, two wrapping and positioning arc plates move in the opposite directions through a pushing column by controlling an opening frame and cooperation strips, the two ends of the two wrapping and positioning arc plates abut against the outer walls of the steel pipes, the situation that the steel pipes roll on the top of the supporting arc plate in the welding process is avoided, meanwhile, when the steel pipes are rotated, the two ends of the two wrapping and positioning arc plates can achieve a limiting effect on the steel pipes, and the situation that the two steel pipes are staggered is avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a pipeline welding joint supporting device. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves; during the use of some steel pipes, welding equipment may be used to directly weld two steel pipes to Increase the length of the pipeline to meet the use of some scenarios. [0003] During the steel pipe welding process, it is usually necessary to use supporting equipment to support the welding ends of the two steel pipes to achieve labor-saving effect, and in the welding process, the steel pipes need to be rotated, so the steel pipes on the top of the supporting equipment usually cannot get much If the steel pipe is well fixed, it is easy to roll during the welding process of the steel pipe, which will affect the welding effect; at the same time, when the steel pipe i...

Problems solved by technology

[0003] During the steel pipe welding process, it is usually necessary to use supporting equipment to support the welding ends of the two steel pipes to achieve labor-saving effect, and in the welding process, the steel pipes need to be rotated, so the steel pipes on the top of the supporting equipment usually cannot get much If the steel pipe is well fixed, it is easy to roll during the welding process of the steel pipe, which will affect the welding effect; at the same time, when the steel pipe is manually controlled to rotate on the top of the support device, it is necessary to lift the steel pipe and then rotate it or directly roll the two steel pipes. At this time, two steel pipes may appear. If the vertical force or rotational force of the root steel pipe is not equal, because the welding point is still in an unstable state at high temperature, it will cause the welding point of the steel pipe to be dislocated or disconnected, which will have a greater impact on the final welding effect of the steel pipe
