The invention discloses a hydraulic slot milling machine winch with a double rotational speed output function. The winch comprises a winding drum, a hydraulic motor assembly and a hydraulic control valve bank, and is characterized in that the hydraulic motor assembly comprises a high-speed end hydraulic motor assembly and a low-speed end hydraulic motor assembly which are mounted at the two sidesof the winding drum respectively in a transmission mode. According to the winch, the high-speed end hydraulic motor assembly drives the winding drum to output torque at a rotational speed n1, the low-speed end hydraulic motor assembly drives the winding drum to output torque at a rotational speed n2, the ratio of n1 to n2 can reach 10:1 or above, accordingly the winding drum outputs a high rotational speed in the startup or shutdown stage to rapidly complete lifting work and outputs a low rotational speed in the working stage to drive a milling wheel to complete slot milling work, energy consumption is reduced, and the working efficiency of a slot milling machine is greatly improved.

    本发明公开了一种双转速输出的液压铣槽机绞车,包括:卷筒、液压马达总成和液压控制阀组,其特征在于:所述液压马达总成包括高速端液压马达总成和低速端液压马达总成,分别传动安装于所述卷筒的两侧;高速端液压马达总成驱动所述卷筒以转速n1输出扭矩,低速端液压马达总成驱动所述卷筒以转速n2输出扭矩,n1:n2可以做到10:1以上,从而使卷筒在启动或关闭阶段输出高转速快速完成升降工作,在工作阶段输出低转速驱动铣轮完成铣槽工作,减少能源消耗并大大提升铣槽机的工作效率。
