Abstract

The invention relates to an anchoring device of a self-elevating drilling platform, in particular to an improved torpedo anchor. The improved torpedo anchor is characterized by comprising a torpedo anchor body, a bottom torsion spring, a bottom torsion spring outer installation frame, a reset casing pipe, a main bearing rod, a lower supporting plate, an upper supporting plate, an upper torsion spring outer installation frame, an upper torsion spring, a feeding frame, a torque transfer pipe, a tail wing shell, a spiral wing and the like. The bottom torsion spring outer installation frame is coaxially matched with the torpedo anchor body, the initial state of the bottom torsion spring outer installation frame is locked by a pin shaft on a bottom locking disc, the bottom torsion spring outer installation frame is matched with the reset casing pipe through threads, the main bearing rod is fixedly connected with the bottom locking disc and coaxially matched with a reset balancing weight, the lower supporting plate is installed on the torpedo anchor body through a connecting pin and connected with the upper supporting plate through the connecting pin, and the upper torsion spring outer installation frame is internally and fixedly connected with the upper torsion spring, and externally matched with the feeding frame through threads. Compared with an existing torpedo anchor, the mechanism is complex, the mass and size of the torpedo anchor are reduced, the anchoring effect is improved, and the torpedo anchor can be taken out more easily.

Description

technical field [0001] The invention relates to an anchoring device of a self-elevating drilling platform, in particular to an improved torpedo anchor. Background technique [0002] In recent years, as the taut leg mooring system has become a major method of deep-sea mooring, based on the research and application maturity of mooring foundations, there are two main types of mooring foundations for deep water and ultra-deep waters: One type mainly includes suction caisson anchors and normal bearing anchors, and the latter type mainly includes suction embedded flat plate anchors and torpedo anchors. [0003] The torpedo anchor is a deep-water penetration anchor with simple and economical design and construction, convenient installation and low cost, accurate installation and positioning without the need for ROV, and can penetrate the seabed soil to a certain depth without external power. It is suitable for deep water, The most promising mooring foundation in ultra-deep waters,...
