Alternative movable mechanism applied to offshore oilfield wellhead platform pipeline rack

Abstract

The invention provides an alternative movable mechanism applied to an offshore oilfield wellhead platform pipeline rack. The alternative movable mechanism achieves the shinning on a pipeline by the alternative movement of an upper shinning device and lower shinning device under the action of a transmission device. The alternative movable mechanism applied to the offshore oilfield wellhead platformpipeline rack can achieve the shinning on a straight pipeline, the shinning on a bent pipeline and the rotation with 360 degrees around the pipeline, and the operation and control are simple. By theshinning on the straight pipeline, the shinning on the bent pipeline and the rotation with 360 degrees around the pipeline, marine organisms attached to the pipeline can be cleaned, at the same time,different side faces of the pipeline can be cleaned, and the omni-directional cleaning of the pipeline is achieved. The alternative movable mechanism applied to the offshore oilfield wellhead platformpipeline rack has the advantages that the structure is simple, the operation is convenient, the mechanism has higher cleaning efficient, the cleaning cost is reduced, the freeweight cleaning is achieved, and the damage of the severe environment on workers can be also avoided.

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 ...
