The invention provides a winch hydraulic control system and an operation machine, and relates to the field of winch control, the winch hydraulic control system comprises a winch speed reducer with a first input end and a second input end, and the speed ratio of the first input end is smaller than that of the second input end; the first motor is connected with the first input end, and the first motor drives the winch speed reducer to rotate in a first working mode; the second motor is connected with the second input end, and the second motor drives the winch speed reducer to rotate in the second working mode. According to the winch hydraulic control system, through the winch speed reducer provided with the first input end and the second input end, the first input end with the low speed ratio is connected with the first motor, rapid lifting and lowering of a winch in the first working mode are achieved, the second input end with the high speed ratio is connected with the second motor, and rapid lifting and lowering of the winch in the second working mode are achieved. And lifting and low-speed lowering of the winch in the second working mode are achieved, and the second motor can stably operate in the process that the winch is lowered at the extremely low speed.

    本发明提供一种卷扬液压控制系统及作业机械,本发明涉及卷扬控制领域,一种卷扬液压控制系统包括:具有第一输入端和第二输入端的卷扬减速机,第一输入端的速比小于第二输入端的速比;第一马达与第一输入端连接,第一马达驱动卷扬减速机在第一工作模式下转动;第二马达与第二输入端连接,第二马达驱动卷扬减速机在第二工作模式下转动。本发明提供的卷扬液压控制系统,通过具有第一输入端和第二输入端的卷扬减速机,实现低速比的第一输入端与第一马达连接,实现第一工作模式下卷扬的快速上提和下放,高速比的第二输入端与第二马达连接,实现第二工作模式下卷扬的上提和慢速下放,达到在卷扬极慢速度下放的过程中,第二马达可以稳定运转。
