The invention discloses a hydraulic walking control system and method and a high-altitude operation vehicle. The system comprises a walking pump, a first flow distributing and collecting valve, a second flow distributing and collecting valve and all walking motors. A port A of the walking pump is connected with a third port of the first flow distributing and collecting valve and a third port of the second flow distributing and collecting valve, and a port B of the walking pump is connected with a port B of the left front walking motor, a port B of the left rear walking motor, a port A of the right front walking motor and a port A of the right rear walking motor. A fourth port of the first flow distributing and collecting valve is connected with a port A of a left front walking motor, and a second port of the first flow distributing and collecting valve is connected with a port A of a left rear walking motor; a fourth port of the second flow distributing and collecting valve is connected with a port B of the right front walking motor, and a second port of the second flow distributing and collecting valve is connected with a port B of the right rear walking motor. The problem that the walking effect is affected due to the fact that flow and pressure change is caused by slipping during walking is solved.

    本发明公开了一种液压行走控制系统、控制方法及高空作业车辆,所述系统包括行走泵、第一分流集流阀、第二分流集流阀以及各行走马达;所述行走泵的A口与第一分流集流阀和第二分流集流阀的第三口连接,所述行走泵的B口与左前行走马达的B口、左后行走马达的B口、右前行走马达的A口、右后行走马达的A口连接;所述第一分流集流阀的第四口与左前行走马达的A口连接,所述第一分流集流阀的第二口与左后行走马达的A口连接;所述第二分流集流阀的第四口与右前行走马达的B口连接,所述第二分流集流阀的第二口与右后行走马达的B口连接。本发明避免了行走时由于打滑导致流量和压力出现变化,进而影响行走效果的问题。
