Hydraulic control system of brake of winch

The invention provides a hydraulic control system of a brake of a winch, and belongs to the technical field of hydraulic control. The hydraulic control system comprises a power unit, an oil inlet unit and an oil return unit, and the oil inlet unit is communicated with the power unit and used for controlling pressure oil from the power unit to enter one of the first brake and the second brake. The first brake is used for conducting emergency braking on the winch when the winch encounters an accident, and the second brake is used for conducting braking on the winch when the winch works. The oil return unit communicates with the first brake and the second brake, and the oil return unit is used for selectively guiding pressure oil in the first brake and the second brake into the oil tank. The braking efficiency of the winch can be improved. 本公开提供了一种绞车的制动器的液压控制系统，属于液压控制技术领域。所述液压控制系统包括动力单元、进油单元以及回油单元，所述进油单元与所述动力单元连通，用于控制来自所述动力单元的压力油分别进入到第一制动器以及第二制动器中的一个，所述第一制动器用于在所述绞车遇到意外时对所述绞车的进行紧急制动，所述第二制动器用于在绞车工作时对所述绞车进行制动；所述回油单
