The invention provides a flexible energy-saving speed-limiting control system for the free anchoring of a large windlass. The system comprises a windlass brake oil cylinder, a one-way throttle valve,a two-position four-way electromagnetic reversing valve, a pressure reducing valve, a clutch oil cylinder, a pressure gauge, a one-way valve and a main safety valve. One side of an oil outlet of a hydraulic pump is connected with a port P of the main safety valve through the one-way valve, the other side of the oil outlet of the hydraulic pump is connected with a working oil cavity of the windlassbrake oil cylinder through the pressure reducing valve, the electromagnetic reversing valve and the one-way throttle valve, an oil suction port of the hydraulic pump is connected with a hydraulic oiltank through a hydraulic pipeline, the clutch oil cylinder is connected to the two-position four-way electromagnetic reversing valve and the pressure reducing valve, and the one-way throttle valve isarranged on the clutch oil cylinder. The system can automatically adjust an electric proportional overflow valve at the outlet of the pump so as to adjust the magnitude of brake force, and when the large windlass breaks down, the speed is limited within the required range, and impact out-of-control is avoided.

    一种大型锚机自由抛锚柔性节能限速控制系统,包括锚机刹车油缸、单向节流阀、两位四通电磁换向阀、减压阀、离合器油缸、压力表、单向阀、主安全阀;液压泵的出油口一边经单向阀与主安全阀的P口相连,另一边通过减压阀、电磁换向阀、单向节流阀与锚机刹车油缸的工作油腔相连,吸油口通过液压管路与液压油箱相连,离合器油缸与两位四通电磁换向阀和减压阀相连,离合器油缸上装有单向节流阀。该系统可以自动调节泵出口的电比例溢流阀,从而调节刹车力的大小,当大型锚机抛锚时,将速度限制在要求范围内,避免冲击失控。
