The invention provides a winch unloading system which comprises a hydraulic pump station and a winch control system, the hydraulic pump station supplies oil to the winch control system, the winch control system drives a motor to rotate, and the winch control system comprises a first middle-position unloading valve and a first operating valve. An oil outlet of the hydraulic pump station is connected with the P end of the first operating valve through a first oil outlet pipeline, the T end of the first operating valve is connected with an oil return opening of the hydraulic pump station through a first oil return pipeline, the A end of the first operating valve is connected with a first port of the motor, and the B end of the first operating valve is connected with a second port of the motor. A first middle-position unloading valve is arranged between the first oil inlet pipeline and the first oil return pipeline; by means of the structure, when the winch is standby, oil supplied by the hydraulic pump station can be unloaded and flow back to the oil tank, and therefore it is guaranteed that an oil way of the hydraulic system can circulate at low pressure, and energy consumption of the hydraulic system is small.

    本发明提供一种绞车的卸荷系统,包括液压泵站和绞车控制系统,所述液压泵站向绞车控制系统供油,绞车控制系统驱动马达进行转动,所述绞车控制系统包括第一中位卸荷阀和第一操纵阀,所述液压泵站的出油口通过第一出油管道连接第一操纵阀的P端,第一操纵阀的T端通过第一回油管道连接液压泵站的回油口,第一操纵阀的A端连接马达的第一端口,第一操纵阀的B端连接马达的第二端口,第一进油管道和第一回油管道之间设有第一中位卸荷阀;上述结构,在绞车待机时,液压泵站供的油能够被卸荷流回油箱,从而保证液压系统的油路能够低压循环,使得液压系统的耗能较小。
