The invention relates to the field of aerial work machinery, and discloses a working platform hydraulic system and an electric aerial work platform, the working platform hydraulic system comprises a platform oil cylinder hydraulic loop and a platform power unit, and the platform power unit is arranged on the working platform and independently supplies oil to the platform oil cylinder hydraulic loop. In the electric aerial work platform adopting the working platform hydraulic system, a lower vehicle oil pump for supplying oil to a main arm working loop and a platform power unit on the working platform are mutually independently distributed. By means of distributed arrangement of hydraulic power, oil is independently supplied to a platform oil cylinder hydraulic loop through the platform power unit additionally arranged on the working platform, a working platform hydraulic system is separated from other action hydraulic systems, pressure redundancy waste is avoided when small-flow and high-pressure platform action and large-flow and low-pressure action are combined, and the working efficiency is improved. The energy efficiency is improved, complex hydraulic pipeline connection is avoided, energy consumption is reduced, and long-distance electric transmission of energy is achieved.
本申请涉及高空作业机械领域,公开了一种工作平台液压系统和电动高空作业平台,工作平台液压系统包括平台油缸液压回路及平台动力单元,平台动力单元设置于工作平台上并为所述平台油缸液压回路独立供油。在采用该工作平台液压系统的电动高空作业平台中,为主臂工作回路供油的下车油泵和工作平台上的平台动力单元相互独立地分布式布置。本申请通过液压动力的分布式布置,使得平台油缸液压回路由工作平台上增设的平台动力单元独立供油,使工作平台液压系统与其他动作液压系统分离,小流量高压力的平台动作与大流量低压力动作复合动作时,不会造成压力冗余浪费,提高了能效,还避免了繁复的液压管路连接、减少能耗,实现能量长距离电传。
