The invention discloses a chassis of an aerial work platform and the aerial work platform. The chassis of the aerial work platform comprises an axle, a frame and an axle balance system, the axle is indriving connection with a walking motor, the frame is located above the axle, the axle balance system comprises a balance oil cylinder connected between the axle and the frame and an electromagneticvalve set connected between an oil supplementing oil way and the balance oil cylinder, and when the aerial work platform is in a walking state, the electromagnetic valve set is powered on and enablesa rod cavity and a rodless cavity of the balance oil cylinder to be communicated. When the aerial work platform is in an operation state, the electromagnetic valve set is powered off, and the rod cavity and the rodless cavity of the balance oil cylinder are locked. When the aerial work platform is in a walking state, the electromagnetic valve set is powered on so that the two oil cavities of the balance oil cylinder can be communicated, the axle can be in a floating state, the hydraulic pump does not need to be started at the moment, energy consumption can be reduced, and then the endurance ofthe electric drive self-walking aerial work platform is improved.
本发明公开了一种高空作业平台的底盘和高空作业平台。高空作业平台的底盘包括车桥、车架和车桥平衡系统,车桥与行走电机驱动连接,车架位于车桥的上方,车桥平衡系统包括连接于车桥和车架之间的平衡油缸和连接于补油油路和平衡油缸之间的电磁阀组,在高空作业平台处于行走状态时,电磁阀组得电并使平衡油缸的有杆腔和无杆腔连通;在高空作业平台处于作业状态时,电磁阀组断电并使平衡油缸的有杆腔和无杆腔均锁止。当本发明的高空作业平台处于行走状态,电磁阀组得电以使得平衡油缸的两个油腔相通进而使得车桥处于浮动状态,此时液压泵无需启动,因此可降低能耗,进而提高电动电驱自行走式高空作业平台的续航能力。
