Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the pipeline self-adaptive device of the prior art has a small clamping force and cannot firmly hold pipelines with different diameters, and the self-adaptive effect is relatively poor. It can firmly hold pipes of different diameters, and has a good self-adaptive effect. It is an adaptive device for underwater pipes.

Abstract

The invention relates to the field of mechanical equipment, and provides a self-adaptive device for an underwater pipeline. The holding force is large, pipelines of different pipe diameters can be firmly held, and the self-adaptive effect is good. The self-adaptive device comprises a control mechanism and at least one multi-stage holding mechanisms, each multi-stage holding mechanism comprises a base plate and two sets of matched holding assemblies arranged on one side of the base plate, each holding assembly comprises at least three stages of matched, sleeved and linked arc holding pieces, and under control of the control mechanism, the holding pieces of the stages are linked to a holding / loosening pipeline stage by stage through connecting pieces. The self-adaptive device solves the problems that an existing pipeline self-adaptive device is small in holding force, cannot hold pipelines of different pipe diameters firmly, and is poor in self-adaptive effect.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an adaptive device for underwater pipelines. Background technique [0002] At present, the construction of offshore mining platforms requires the support of cylindrical structures such as steel pipe piles and jackets, and the extraction of offshore oil and natural gas needs to be transported through pipelines. Due to long-term immersion in seawater, pipes such as jackets are prone to rust or adhere to marine organisms, which affects the service life of the pipes, so regular cleaning is required. Moreover, some important pipelines also need to be inspected and maintained regularly to prevent environmental pollution caused by leakage of materials inside the pipelines. Underwater manual work has a high risk, so the inspection, maintenance or other operations of underwater pipelines require crawling robots outside the pipe. [0003] The existing pipeline adaptive devic...
