The invention discloses a winch control valve bank and a winch control hydraulic system.The winch control valve bank comprises a control valve bank body, a port A1, a port B1, a port A, a port B, a port T and a port X. The port A1, the port B1, the port A, the port B, the port T and the port X. The control valve bank body comprises a balance valve, a one-way overflow valve, an electromagnetic ball valve, a first one-way valve and a shuttle valve, and the port A of the balance valve is communicated with the port A1 of the control valve bank; a port B of the balance valve communicates with a port P2 of the shuttle valve and a port A of the control valve set. A Y port of the balance valve is respectively communicated with a P1 port of the shuttle valve, a T port of the one-way overflow valve, a B port of the electromagnetic ball valve and a B port of the control valve group; a port P3 of the shuttle valve is communicated with a port X of the control valve group; a port P of the one-way overflow valve is respectively communicated with a port B1 of the control valve group, a port A of the electromagnetic ball valve and a port B of the first one-way valve; a port A of the first one-way valve communicates with a port T of the control valve set. The system has redundancy design of safety braking, and is safer and more reliable.

    本发明公开了一种卷扬控制阀组及卷扬控制液压系统,卷扬控制阀组采用控制阀组本体及与控制阀组本体相连接的A1口、B1口、A口、B口、T口和X口,控制阀组本体包括平衡阀、单向溢流阀、电磁球阀、第一单向阀和梭阀,平衡阀的A口与控制阀组的A1口相接通,平衡阀的B口分别与梭阀的P2口和控制阀组的A口相接通;平衡阀的Y口分别与梭阀的P1口、单向溢流阀的T口、电磁球阀的B口和控制阀组的B口相接通;梭阀的P3口与控制阀组的X口相接通,单向溢流阀的P口分别与控制阀组的B1口、电磁球阀的A口和第一单向阀的B口相接通;第一单向阀的A口与控制阀组的T口相接通。本发明具备安全制动的冗余设计,系统更安全、可靠。
