Description

Technical Field

[0001] The utility model relates to an adjustment mechanism, in particular to a pipe group adjustment device. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. In the process of pipeline construction, it is often encountered that the pipeline is teamed.

[0003] However, due to improper processing or transportation measures, the pipe mouth is often not round when it is assembled on site. It is necessary to adjust the ovality of the pipe mouth on the construction site so that the assembly quality meets the requirements of the specifications. When adjusting the ovality of the pipe mouth, a temporary structure is often welded on the steel pipe (such as welding a saddle card on the steel pipe and beveled shoulder method) to adjust the ovality of the pipe mouth. However, this method is very inconvenient to dismantle the temporary structure. Therefore, a pipe assembly adjustment device is proposed to optimize and solve the above problems.
