摘要
The present invention relates to a hydraulic inclined jacking installation system for offshore wind turbines, which comprises a wind turbine installation vessel, a rotating device, a hydraulic system and wind turbine arrangement lifting devices. Stern posts are vertically mounted on the stern of a deck, and stern guide rails are disposed on the stern posts. The rotating device comprises gear lifting mechanisms, rotating arms and machine hands. The gear lifting mechanisms slide up and down along the stern guide rails, and one ends of the rotating arms are hinged to the gear lifting mechanisms. The hydraulic system comprises hydraulic power units, hydraulic bases and telescopic hydraulic cylinders hinged to the hydraulic bases. The top ends of the telescopic hydraulic cylinders are hinged to the rotating arms. The hydraulic power units drive the telescopic hydraulic cylinders to extend and contract to jack the rotating arms to rotate. The wind turbines are horizontally arranged on the wind turbine arrangement lifting devices, and the machine hands hold towers of the wind turbines. After the machine hands hold the towers of the wind turbines, the hydraulic system jacks the rotating arms upward to rotate around a stern beam. Meanwhile, the stern beam can move up and down along the stern guide rails. Two ends of the rotating arms work together to shorten the installation time of one offshore wind turbine.
