The invention provides a hydraulic winding system. The hydraulic winding system comprises an oil tank, a load-sensitive variable pump assembly, an electromagnetic proportional directional valve, a balance valve, a metering pump, a first hydraulic operated directional valve, a hydraulic motor and a system oil drainage pipeline communicating with the oil tank. The oil tank, the load-sensitive variable pump assembly and the electromagnetic proportional directional valve communicate with a high-pressure cavity of the hydraulic motor. The balance valve communicates with the high-pressure cavity andthe electromagnetic proportional directional valve. The oil tank and the metering pump communicate with the first hydraulic operated directional valve, and the first hydraulic operated directional valve communicates with the high-pressure cavity and a low-pressure cavity. A pipeline between the first hydraulic operated directional valve and the low-pressure cavity and a pipeline between the firsthydraulic operated directional valve and the high-pressure cavity communicate with the system oil drainage pipeline. The hydraulic winding system has the advantages that exhausting, oil supplementingand exhausting can be carried out on the hydraulic motor so that the situation that the hydraulic motor overspeeds instantly and then stalls can be avoided, and system part damage is avoided.

    本发明提供了一种液压卷扬系统,包括油箱、负载敏感变量泵组件、电磁比例换向阀、平衡阀、定量泵、第一液控换向阀、液压马达和与油箱连通的系统泄油管路,油箱、负载敏感变量泵组件、电磁比例换向阀和液压马达的高压腔连通,平衡阀与高压腔和电磁比例换向阀均连通;油箱、定量泵和第一液控换向阀连通,第一液控换向阀与高压腔和低压腔均连通;第一液控换向阀与低压腔之间的管路以及第一液控换向阀与高压腔之间的管路均和系统泄油管路连通。本发明的有益效果:能够对液压马达进行排气补油排气,以能够避免液压马达出现瞬间超速进而出现失速的情况,以此避免系统出现零件损坏。
