Problems solved by technology

[0004] When the existing piling machinery implements offshore piling operations, it uses flanges and bolts to fix the pile frame. Every time the pile frame moves, it needs to be fixed again, which is time-consuming and laborious, and has the disadvantage of low operating efficiency.

Abstract

The invention relates to the technical field of wind power, in particular to a hydraulic control device for offshore wind power piling. Offshore wind power piling efficiency is improved. The device comprises an oil tank, an oil supply motor pump set, an air cooling circulating pump and three oil cylinder sets. The oil supply motor pump set comprises an oil supply motor pump, an oil supply filter and an oil supply overflow valve. An oil pumping opening of the oil supply motor pump is connected to a system oil supply pipe through the oil supply filter and is connected to the oil tank through the oil supply overflow valve. The system oil supply pipe is connected with at least one energy storage device. Oil cylinders in a first oil cylinder set and a second oil cylinder set are respectively provided with a reversing valve. Oil cylinders of a third oil cylinder set are respectively provided with a servo valve. Working openings of the reversing valves and working openings of the servo valves are connected working cavities of the oil cylinders which the valves belong to. Oil returning openings of the reversing valves and oil returning openings of the servo valves are connected to the oil tank. Pressure oil openings of the oil cylinders are connected to the system oil supply pipe. The device is suitable for mounting of an offshore wind power plant.

Description

technical field [0001] The invention relates to wind power technology, in particular to the technology of a hydraulic control device for offshore wind power piling. Background technique [0002] Offshore wind resources are more abundant than those on land, so building wind farms offshore is the trend of wind power development. However, the installation of offshore wind power is more difficult than that of land wind power, especially the installation of foundations and wind power towers. [0003] When installing offshore wind power bases and wind power towers, piling machines need to be used to drive piles on the seabed. Existing pile machinery is mainly composed of pile hammer, pile frame and auxiliary equipment, etc. The pile frame is a steel structure tower frame, and a crane is arranged at the rear part to lift the pile and pile hammer, and the pile hammer is attached to the front of the pile frame. Between the two parallel vertical guide rods at the top, a guide frame ...
