The invention discloses a suction cup accessory hydraulic control system and a high-altitude operation suction cup truck, a suction cup accessory comprises a plurality of accessory action executing mechanisms, and the suction cup accessory hydraulic control system comprises a working pressure oil way and a main oil return oil way; the accessory action hydraulic loops are connected to the working pressure oil way and the main oil return oil way in parallel, and each accessory action hydraulic loop comprises a corresponding accessory action executing mechanism and an accessory action reversing valve used for switching and controlling the accessory action executing mechanism; and the shared proportional valve is arranged at the oil inlet end of the working pressure oil way. According to the hydraulic control system capable of controlling the actions of the multiple accessories through one proportional valve, namely, the single shared proportional valve and the multiple accessory action hydraulic loops are connected to the working pressure oil way and the main oil return way in parallel, so that the single proportional valve controls the actions of the multiple accessories, the number of the proportional valves is greatly reduced, and the cost is reduced. The structure of the hydraulic system is simplified, and the system cost is reduced.
本申请公开了一种吸盘属具液压控制系统和高空作业吸盘车,吸盘属具包括多个属具动作执行机构,吸盘属具液压控制系统包括工作压力油路和主回油油路;多个属具动作液压回路,并联连接于工作压力油路和主回油油路,每个属具动作液压回路均包括相应的属具动作执行机构和用于切换控制属具动作执行机构的属具动作换向阀;以及共用比例阀,设置在工作压力油路的进油端。本申请针对性设计了一种一个比例阀可控制多个属具动作的液压控制系统,即采用单个的共用比例阀,多个属具动作液压回路并联连接于工作压力油路和主回油油路,从而实现单个比例阀控制多个属具动作,大大减少了比例阀个数,简化了液压系统的结构,降低了系统成本。
