Embodiment Construction

[0021] refer to figure 1 and figure 2 , a hydraulic winch for controlling the attitude of a submersible tension leg platform, comprising a wire rope 1. The steel wire rope 1 is coated with a special lubricating paint that is insoluble in water and does not pollute the environment. During the two processes of winding the steel wire rope 1 into strands and strands into ropes, a special brushing process is carried out twice to ensure that the paint can be fully and evenly applied to the surface. Between the wires of the steel wire rope 1 and between the strands and the strands. Thereby reducing the wear between the steel wire rope 1 and the reel 3 and the pulley. The hydraulic winches are installed on deck 2 of the submersible TLP. The hydraulic winches include tension winches and mooring winches. The number of tension winches is four, and the number of mooring winches is four. The tension winches and hydraulic winches have the same structure. The hydraulic winch includes a r...

Abstract

The invention discloses a hydraulic winch capable of controlling submerging type tension leg platform gesture precisely and belongs to the technical field of ships. The device comprises a steel wire rope. The hydraulic winch is installed on a deck of the submerging type tension leg platform. The hydraulic winch comprises a winding drum, a winding drum shaft supporting plate and a binaural plate hinge supporting seat hinge shaft. The steel wire rope is wound on the winding drum. A winding drum shaft is installed in the winding drum. The winding drum shaft is connected with the winding drum shaft supporting plate. The winding drum shaft supporting plate is connected with the binaural plate hinge supporting seat through the binaural plate hinge supporting seat hinge shaft. The binaural plate hinge supporting seat is connected with the base seat. The base seat is fixed on the deck of the submerging type tension leg platform. A movable sealing structure is arranged between the winding drum shaft and the winding drum shaft supporting plate. A sealing ring is installed between the winding drum shaft and the winding drum shaft supporting plate. A stainless steel U-shaped spring piece is installed in the sealing ring. The hydraulic winch can be operated under the diving operating mode.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to a hydraulic winch for controlling the posture of a submersible-floating tension leg platform. Background technique [0002] TLP generally consists of three parts: platform body, tension legs and underwater anchoring system. The main idea of ​​TLP design is to make the platform semi-compliant and semi-rigid. [0003] The winch is an integral part of the tension leg platform. At present, most of the tension leg platforms are above-water platforms, and there are no tension legs suitable for underwater platforms, so the winches for controlling the tension legs of the above-water platforms are all arranged on the deck on the water surface. Ordinary winches are connected to the reel shaft by an electric motor or a hydraulic motor through an external reduction box, and the reel shaft is generally connected to the winch base through a bearing seat and its base. The brake of the winch usu...
