The invention provides an oil extraction method for double winches, which comprises the following specific steps that: (1) a hydraulic pump station supplies oil to a winch control system, and the winch control system drives a motor and a second motor to operate; (10) when one motor is required to work and the other motor is in a standby state; (11) the hydraulic oil flows to a first unloading shuttle valve through the first operating valve or the second operating valve, and a first port of the first unloading shuttle valve is communicated with a third port or a second port of the first unloading shuttle valve is communicated with the third port; (12) the hydraulic oil flows to the second control end of the first middle-position unloading valve and the second control end of the second middle-position unloading valve through a third port of the first unloading shuttle valve; (13) the first middle-position unloading valve and the second middle-position unloading valve are closed, and the hydraulic oil normally flows to the motor needing to work and drives the motor to operate; according to the method, when only one winch needs to be started, the unloading oil way of the standby winch is closed, and therefore it is guaranteed that the hydraulic oil can output enough oil pressure to drive the working winch to act.

    本发明提供一种双绞车的取油方法,具体步骤包括:(1)液压泵站向绞车控制系统供油,绞车控制系统驱动马达和第二马达运行;(10)当需要其中一台马达工作,另一台马达待机时;(11)液压油经过第一操纵阀或第二操纵阀流向第一卸荷梭阀,第一卸荷梭阀的第一端口与第三端口连通或第二端口与第三端口连通;(12)液压油经过第一卸荷梭阀的第三端口流向第一中位卸荷阀的第二控制端和第二中位卸荷阀的第二控制端;(13)第一中位卸荷阀和第二中位卸荷阀关闭,液压油正常流向需要工作的马达并驱动马达运作;以上方法,当仅需要一台绞车启动时,关闭待机绞车的卸荷油路,从而保证液压油能够输出足够的油压驱动工作的绞车进行动作。
