The invention discloses an aerial work platform and a four-wheel-drive walking control system. The control system comprises a flow distributing and collecting device, a first hydraulic control valve, a second hydraulic control valve, a flushing valve, a shuttle valve and a control valve. A first oil port and a second oil port of the flow distributing and collecting device are respectively communicated with a port B and a port A of a left rear travel motor, a third oil port of the flow distributing and collecting device is communicated with a port B of a left front travel motor, a fourth oil port of the flow distributing and collecting device is communicated with a port A of the left front travel motor through a first hydraulic control valve, a fifth oil port of the flow distributing and collecting device is communicated with a port A of a right rear travel motor, and the fourth oil port is also communicated with a port B of the right rear travel motor; the sixth oil port is communicated with a port A of the right front walking motor, and the second oil port is communicated with a port B of the right front walking motor through the second hydraulic control valve. The problem that due to the fact that the front wheels slip or suspend in the air, all hydraulic oil for driving the whole vehicle to walk does idle work through the idling motor, and the whole vehicle cannot walk under the abnormal condition is solved.

    本发明公开了一种高空作业平台及四驱行走控制系统,所述控制系统包括分流集流装置、第一液控阀、第二液控阀、冲洗阀、梭阀以及控制阀;分流集流装置的第一油口和第二油口分别连通左后行走马达的B口和A口,其第三油口连通左前行走马达的B口,其第四油口通过第一液控阀连通左前行走马达的A口,其第五油口连通右后行走马达的A口,其第四油口还连通右后行走马达的B口,其第六油口连通右前行走马达的A口,其第二油口还通过第二液控阀连通右前行走马达的B口。本发明避免了因前轮打滑或悬空,使得驱动整车行走的液压油全部通过空转的马达做无用功,无法实现异常情况下的整车行走问题。
