Alternative moving mechanism applied to pipeline frame of offshore oilfield wellhead platform

Abstract

The invention provides an alternate moving mechanism applied to the pipeline frame of the offshore oilfield wellhead platform. Under the action of the transmission device, the alternate moving mechanism realizes climbing on the pipeline through the alternate movement of the upper climbing device and the lower climbing device. . The alternate moving mechanism applied to the pipeline frame of the offshore oilfield wellhead platform provided by the present invention can realize straight pipeline crawling, curved pipeline crawling and 360° rotation around the pipeline, and is easy to operate. Through the linear pipeline crawling, curved pipeline crawling and 360° rotation around the pipeline of the alternating moving mechanism, the marine organisms attached to the pipeline can be cleaned, and different sides of the pipeline can be cleaned at the same time, so as to realize the all-round cleaning of the pipeline. The alternate moving mechanism applied to the pipeline frame of the offshore oilfield wellhead platform provided by the present invention has the advantages of simple structure, convenient operation, high cleaning efficiency, low cleaning cost, load-bearing cleaning, and can avoid harm to workers caused by harsh environments.

Description

technical field [0001] The invention relates to the technical field of pipe climbing, in particular to an alternate moving mechanism applied to a pipe frame of a wellhead platform in an offshore oil field. Background technique [0002] With the continuous growth of social economy, the exploitation of marine resources has been paid more and more attention. Among the many marine resources, the offshore oil located in the bedrock of the seabed is one of the important marine resources. Among the global oil resources, the world's offshore oil resources can account for 34% of the total global oil resources. Therefore, offshore oil reserves are abundant and have great significance for exploitation. [0003] In the process of offshore oil exploitation, it is necessary to establish an offshore oil platform in the ocean to facilitate the placement of various oil extraction equipment. The establishment of offshore oil platforms requires a large number of steel pipes and jackets, and ...
