Abstract

The invention relates to the field of mechanical equipment and aims to provide a self-adaptive device for a jacket of a drilling platform. The self-adaptive device can be self-adaptive to jackets of different pipe diameters and shapes initiatively and is simple in structure, light, small in self weight, high in flexibility and good in self-adaptive effect. The self-adaptive device comprises a bottom plate (1), and a connecting rod mechanism, a connecting rod driving mechanism, a lever linking mechanism and an adsorbing and enclasping mechanism arranged on the bottom plate (1). The connecting rod mechanism is driven by the connecting rod driving mechanism, and the connecting rod mechanism drives the adsorbing and enclasping mechanism to enclasp the jacket through the lever linking mechanism. The self-adaptive device provided by the invention solves the problem that an existing enclasping mechanism is complex and tedious in structure, common in operating flexibility and 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 a drilling platform jacket. Background technique [0002] At present, most offshore oil wellhead platforms are constructed of steel pipe piles, jackets and decks. Due to long-term immersion in seawater, the jackets in seawater immersion areas and tidal range areas are extremely vulnerable to the attachment of marine organisms, and these attached marine organisms will change the surface roughness and damping coefficient of the jacket and increase the surface area of ​​the jacket. At the same time, the total weight of the jacket is also increased, so that the jacket bears greater weight loads, wave loads and ocean current forces, resulting in a decrease in platform stability and storm resistance, and a greatly increased risk of occurrence. At the same time, the long-term attachment of marine organisms to the surface of the jacket will also inten...
