Shaft mouth platform jacket wheel type moving mechanism orienting offshore oilfield

Abstract

The invention discloses a shaft mouth platform jacket wheel type moving mechanism orienting an offshore oilfield, and belongs to the field of robots. The shaft mouth platform jacket wheel type movingmechanism comprises an upper mechanism body and a lower mechanism body, and an upper clamping mechanism and a lower clamping mechanism are fixed to the upper mechanism body and the lower mechanism body respectively; the upper clamping mechanism comprises an upper rack, the upper rack comprises a rectangular plate and a first baffle and a second baffle located at the two ends of the rectangular plate, and a fixed rod and a first slide block and a second slide block capable of sliding along the fixed rod are arranged between the first baffle and the second baffle; a first clamping plate and a second clamping plate perpendicular to the rectangular plate are fixed to the first slide block and the second slide block respectively, and triangular slide blocks capable of sliding in the length direction of the clamping plates are arranged at both ends of the first clamping plate and the second clamping plate and are provided with idler wheels and speed adjusting motors; the lower clamping mechanism and the upper clamping mechanism are of the same structure. The shaft mouth platform jacket wheel type moving mechanism can replace the job of manually carrying cleaning equipment to dive for underwater cleaning, the manual cost is saved, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wheeled moving mechanism for a jacket facing an offshore oilfield wellhead platform. Background technique [0002] At present, there are more than 100 offshore wellheads in my country, which are important equipment in offshore oil recovery. However, marine organisms on the jacket of the wellhead platform will absorb a large number of them on the jacket for a long time. The attached marine organisms change the roughness and damping coefficient of the jacket surface, increase the surface area of ​​the jacket, increase the total weight of the jacket, and make the jacket bear greater weight load, wave load and ocean current force. The stability of the platform and the ability to resist storms are reduced, and the probability of danger is greatly increased. [0003] At the same time, the long-term attachment of marine organisms to the surface of the jacket also intensifies the corro...

AI Technical Summary

Problems solved by technology

[0003] At the same time, the long-term attachment of marine organisms to the surface of the jacket also intensifies the corrosion of the marine environment on the wellhead platform, and at the same time reduces the smoothness of the conduit wall, increasing the average drift of waves in the surge, sway and yaw directions of the pile legs. force, which poses a huge threat to safe production, so the wellhead platform jacket needs to be cleaned regularly

[0004] At present, the cleaning of the jacket is mainly performed by manually carrying high-pressure water guns and other equipment to clean it. Manual diving cleaning is expensive and has low work efficiency, and it is a challenge to the human body as the depth of the dive increases.
