The hydraulic walking system comprises a walking pump, and the walking pump comprises a first pumping oil feeding port and a second pumping oil feeding port which are formed in the two ends of the walking pump; the first diverter valve is arranged on a pumping oil way connected with the first pumping oil port; the second flow divider valve is arranged on a pumping oil way connected with the second pumping oil port; one end of the walking motor oil way is connected to the end flow dividing opening of the first flow dividing valve, and the other end of the walking motor oil way is connected to the end flow dividing opening of the second flow dividing valve; the two ends of the first diverter valve and the two ends of the second diverter valve are connected with the bypass compensation oil ways; and the adjustable balance oil path is in bypass connection with the two ends of at least one of the first diverter valve and the second diverter valve in a flow adjustable manner. The hydraulic walking system is particularly suitable for a bridge expansion chassis, the problems of pressure overflow, engine flameout and the like caused by the large speed difference of motors on the left side and the right side after bridge expansion can be solved, the walking performance is improved, and the applicability of the walking system is improved.
本申请公开了一种高空作业机械及其液压行走系统,液压行走系统包括行走泵,包括两端的第一泵送油口和第二泵送油口;第一分流阀,设置在与第一泵送油口相连的泵送油路上;第二分流阀,设置在与第二泵送油口相连的泵送油路上;行走马达油路,一端连接于第一分流阀的端部分流口,另一端连接于第二分流阀的端部分流口;旁通补偿油路,第一分流阀的两端和第二分流阀的两端均连接有旁通补偿油路;可调平衡油路,流量可调地旁通连接于第一分流阀和第二分流阀中的至少一者的两端。本申请的液压行走系统尤其适于扩桥底盘,可解决扩桥后由于左右两边的马达速度差大而造成压力溢流、发动机熄火等问题,改善了行走性能并提升行走系统的适用性。
