Boom hydraulic system and concrete pump truck
The invention relates to a boom hydraulic system and a concrete pump truck. The system comprises an oil pump, a boom multi-way valve and executing mechanisms; the oil pump is connected with each control valve in the boom multi-way valve and is used for pumping hydraulic oil to each control valve; and at least one target control valve in the boom multi-way valve is connected with the n executing mechanisms, the target control valves are used for controlling the target executing mechanisms corresponding to an operation instruction input by a user to execute corresponding actions under the actionof the hydraulic oil, wherein n is larger than or equal to 2 and smaller than N, and N is the total number of the executing mechanisms. Due to the fact that at least one target control valve in the boom multi-way valve is connected with the executing mechanisms, compared with the prior art, the number of the control valves can be effectively reduced, and the structure of the boom hydraulic systemis simplified.
本公开涉及一种臂架液压系统及混凝土泵车。系统包括：油泵、臂架多路阀、执行机构；所述油泵与所述臂架多路阀中每一控制阀相连，用于将液压油向每一所述控制阀泵送；所述臂架多路阀中的至少一个目标控制阀与n个所述执行机构相连，所述目标控制阀用于在液压油的作用下控制与用户输入的操作指令对应的目标执行机构执行相应动作，其中，2≤n＜N，N为所述执行机构的总数量。由于臂架多路阀中的至少一个目标控制阀与多个执行机构相连，因此，相较于相关技术，可以有效减少控制阀的数量，简化臂架液压系统的结构。
