A rodless cavity of a first hydraulic oil cylinder of the hydraulic control system communicates with a rodless cavity of a second hydraulic oil cylinder of the hydraulic control system and is connected with a one-way valve, the one-way valve is connected with an electromagnetic reversing valve, and the electromagnetic reversing valve is connected with a hydraulic oil tank and a controller. The controller is configured to detect whether a first difference value between the stroke of the first hydraulic oil cylinder and the stroke of the second hydraulic oil cylinder is larger than a first preset threshold value or not under the condition that a steering control signal for the walking machine is received; and under the condition that the first difference value is larger than a first preset threshold value, the electromagnetic reversing valve is controlled to communicate with the one-way valve, so that hydraulic oil of the hydraulic oil tank enters a rodless cavity of the second hydraulic oil cylinder or the first hydraulic oil cylinder through the one-way valve, and the first difference value is smaller than or equal to the first preset threshold value. According to the scheme, manual errors can be reduced, and the equipment steering precision is improved.
本申请公开了一种用于行走机械的液压控制系统及行走机械,液压控制系统的第一液压油缸的无杆腔和第二液压油缸的无杆腔连通,且均与单向阀连接,单向阀与电磁换向阀连接,电磁换向阀分别与液压油箱、控制器连接,且电磁换向阀通常处于断开状态,控制器被配置成:在接收到针对行走机械的转向控制信号的情况下,检测第一液压油缸的行程与第二液压油缸的行程之间的第一差值是否大于第一预设阈值;在第一差值大于第一预设阈值的情况下,控制电磁换向阀与单向阀连通,使得液压油箱的液压油经单向阀进入第二液压油缸或第一液压油缸的无杆腔,以使第一差值小于或等于第一预设阈值。上述方案,可以减小人工误差,并提高设备转向的精度。
