Abstract

A semi-active wave compensation winch comprises a winch body. The two sides of the winch body are provided with a driving integrated cylinder and a compensation hydraulic system correspondingly, the upper end of one side where the driving integrated cylinder is located is provided with a variable hydraulic motor, and the driving integrated cylinder comprises a driving part, an execution part and an energy storage part which are sequentially arranged in the straight line, the driving part is connected with the execution part through a first connecting base, the execution part is connected withthe energy storage part through a second connecting base, the driving part is connected with the compensation hydraulic system, and the execution part and the energy storage part are connected with afirst working oil port and a second working oil port of the variable hydraulic motor correspondingly, the energy storage part is connected with a high pressure gas cylinder, the compensation hydraulicsystem comprises an oil tank, an oil pump, an energy storage device and an electromagnetic reversing valve, an oil inlet of the oil pump is connected with the oil tank, an oil outlet of the oil pumpis connected with the energy storage device and a first oil port of the electromagnetic reversing valve, the first oil port of the electromagnetic reversing valve is connected with the energy storagedevice, the second oil port is connected with the oil tank, and a third oil port is connected with a first oil conveying pipe and a second oil conveying pipe.

Description

technical field [0001] The invention belongs to the technical field of marine equipment and relates to a semi-active wave compensating winch. Background technique [0002] Due to the impact of waves during ocean operations, the hull or drilling platform will undergo heave motion. In order to ensure that the operation is not affected by the heave movement of the hull, some key winches are required to have their own wave compensation function. Heave compensation can be divided into three categories: passive heave compensation, active heave compensation, and semi-active heave compensation according to its realization type. Among them, most of the passive wave compensation winches are driven by hydraulic pressure and are composed of pulley blocks, hydraulic cylinders and accumulators. Due to their simple structure and stable operation, they are usually suitable for occasions that do not require high compensation performance, such as guide rope winches , underwater base plate w...
