Problems solved by technology

However, this robot can only be applied to ferromagnetic pipelines. The robot moves around the pipeline as a whole. When the space around the pipeline is small, the passability is poor, and it can only work on a single pipeline, and cannot continuously work on multiple pipelines.

Abstract

The invention discloses a moving mechanism around a pipeline. The function of a circumferential movement around the pipeline at 360 degrees is realized on the pipelines in different materials by arranging a telescoping mechanism, a rotating mechanism, and a turnover mechanism. The moving mechanism is small, less in demand of around space of the pipeline, and good in universality. If the moving mechanism is supported, the mechanism can be switched to an adjacent pipeline to carry corresponding tools to work on the next pipeline. With the adoption of a force-closure manner, the supporting force is adjustable, and the mechanism has a better adaptability to complex environments and is more convenient to disassemble and install. The operational reliability is ensured while the agility of the mechanism is guaranteed, and the work efficiency is high.

Description

technical field [0001] The invention relates to a movement mechanism, in particular to a ring pipe movement mechanism. Background technique [0002] Pipeline transportation is widely used for long-distance transportation of oil and natural gas. It is precisely because of its large volume and continuous transportation characteristics that if there is a problem with the pipeline, it will not only affect the normal delivery of the product, but may also cause safety hazards and threaten production safety. Therefore, the cleaning, coating, welding and testing of the pipeline Waiting for homework is very important. [0003] In view of the fact that most of the transportation pipelines are straight and long pipes, it is difficult to cover all the pipeline surfaces in one operation. Therefore, it is necessary for the operating device to move in a circumferential direction relative to the pipeline, adjust the operating device to the best angle, and complete further operations.
