Abstract

The invention discloses a hydraulic lifting system for a ship, and aims to facilitate monitoring in a lifting process. The hydraulic lifting system has the advantages that the operation is safe and reliable, the operability is high, and the cost is effectively reduced. According to the technical scheme, the whole ship is supported by four spud legs, that is, the ship body is fixed on the four spud legs; the ring beams of the spud legs are driven by a plurality of main lifting oil cylinders to perform rising and falling action synchronously, so as to life the whole ship; and the action of the oil cylinders is powered by two sets of hydraulic pump stations at the bow and stern of the ship.

Description

technical field [0001] The invention relates to a marine hydraulic lifting system, in particular to a large-tonnage hydraulic lifting system for a wind power installation ship. Background technique [0002] Wind energy is a sustainable and renewable clean energy. The application of wind power for power generation is widely distributed around the world. At present, many countries have carried out the construction and application of offshore wind power generation. In recent years, my country has also built a number of wind power projects. The foreseeable wind power investment in the future will be even larger. The transportation and installation of offshore wind power equipment have high technical requirements, requiring ships hoisting wind power components to be in a stable and reliable environment, so this type of ship will not be affected by waves during operation It has the function of automatic lifting. [0003] At present, there are many types of equipment used in the con...
