The invention discloses a self-lifting offshore wind power work platform lifting mechanism and a lifting method thereof. The self-lifting offshore wind power work platform lifting mechanism comprises a pile fixing frame, a sliding block guide rail, sliding blocks, pull rods, a lifting oil cylinder, bolts and a bolt oil cylinder. The lower end of the pile fixing frame is fixed to a ship body and arranged on the outer side of a pile leg in a sleeving mode. The sliding block guide rail is arranged on the side face of the pile fixing frame. The lower ends of the pull rods are hinged to the upper side of the sliding block guide rail. The upper ends of the pull rods are hinged to the upper side of the sliding block guide rail. The sliding blocks are slidably arranged on the sliding block guide rail and can slide in the vertical direction. The upper end of the lifting oil cylinder is hinged to the upper side of the sliding block guide rail. The lower end of the lifting oil cylinder is hinged to the sliding blocks. The bolt oil cylinder is horizontally arranged and fixed to the sliding blocks. The bolts are arranged in the radial direction of the pile leg, and the ends of the bolts are connected with the bolt oil cylinder and driven by the bolt oil cylinder to move in the radial direction of the pile leg. The pile leg is provided with a plurality of round holes matched with the bolts at equal intervals in the vertical direction. According to the self-lifting offshore wind power work platform lifting mechanism and the lifting method thereof, the lifting efficiency is high, the structure is simple, the cost is low, operation is reliable, and maintenance is convenient.
Description
technical field [0001] The invention relates to a lifting mechanism and a lifting method thereof, in particular to a lifting mechanism and a lifting method of a self-elevating offshore wind power operation platform. Background technique [0002] With the development of offshore wind farms and the optimization of the location of offshore wind farms, the development trend of marine wind energy is large-scale projects and deep water areas characterized by hundreds of wind turbines. The installation of wind turbines will encounter more difficulties, which will affect the performance of the installation ship. and higher portability requirements. Offshore wind power installation operations need to be frequently moved from one location to another, and its lifting system works frequently. The lifting speed has a great influence on the operation time and work efficiency. The development of the lifting speed of the wind power installation ship's lifting system requires faster and mor...
