The invention provides a hydraulic control system of an underwater winch, and belongs to the technical field of hydraulic control. The hydraulic control system comprises a variable pump, a winch driving valve group, a brake driving valve group and an oil tank; the winch driving valve group comprises a proportional directional valve, a first electromagnetic directional valve and a second electromagnetic directional valve, the brake driving valve group comprises a pressure reducing valve and a third electromagnetic directional valve, and a second oil port of the third electromagnetic directional valve is communicated with a rod cavity of the brake driving oil cylinder; and a third oil port of the third electromagnetic directional valve is communicated with the oil tank. The cost of the system can be reduced, and after the reversing valve breaks down, the motor can still be controlled to rotate so that cable laying can be achieved.

    本公开提供了一种水下绞车的液压控制系统,属于液压控制技术领域。所述液压控制系统包括变量泵、绞车驱动阀组、制动器驱动阀组以及油箱;所述绞车驱动阀组包括比例换向阀、第一电磁换向阀和第二电磁换向阀,所述制动器驱动阀组包括减压阀以及第三电磁换向阀,所述第三电磁换向阀的第二油口与制动器驱动油缸的有杆腔连通,所述第三电磁换向阀的第三油口与所述油箱连通。本公开可以降低系统的成本,且在换向阀故障之后依然可以控制马达转动而实现放缆。
