A high-precision hydraulic synchronous lifting control system for wind power installation ships

Abstract

The invention provides a high-accuracy hydraulic synchronous lifting control system of a wind installation vessel. The high-accuracy hydraulic synchronous lifting control system of the wind installation vessel comprises a hydraulic transmission module, a hydraulic control module and an electric control module. The hydraulic transmission module comprises a base, a spud leg and four hydraulic transmission assemblies, wherein the spud leg is fixed to the base, and a lug seat is arranged on the base. The hydraulic transmission assemblies comprise the left transmission assembly, the rear transmission assembly, the right transmission assembly and the front transmission assembly of the same structure. The hydraulic control module comprises a hydraulic oil tank, hydraulic pipelines, an air filter, a motor, a hydraulic pump, a check valve, an overflowing valve, four hydraulic transmission control assemblies and four hydraulic bolt control assemblies, wherein the hydraulic pump is connected with the motor; one end of the hydraulic pump is connected with the oil tank through the hydraulic pipeline and the air filter; and the other end of the hydraulic pump is connected with the hydraulic transmission control assemblies and the hydraulic bolt control assemblies through the hydraulic pipelines. The high-accuracy synchronous lifting control system of the wind installation vessel resolves the problem of leakage of a hydraulic system, non-linear friction resistance of execution components and the like, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of jack-up offshore installation engineering platforms, in particular to a high-precision hydraulic synchronous lifting control system for wind power installation ships, specifically a high-precision transmission control scheme for legs of jack-up offshore installation engineering platforms. Background technique [0002] The leg transmission mode of the self-elevating offshore installation engineering platform includes two types of rack and pinion transmission and hydraulic transmission. Rack and pinion transmission has a simple structure and is easy to control. Cylindrical legs are generally driven by rack and pinion, but the racks are prone to corrosion after long-term immersion in seawater, which affects the service life of the legs. Hydraulic transmission is often used on pile legs with polygonal structures. All hydraulic transmission components are installed above sea level, so they are not affected by ...
