The invention discloses a high-speed hydraulic erecting mechanism based on a synchronous telescopic multi-stage cylinder and an energy accumulator. The high-speed hydraulic erecting mechanism comprises the synchronous telescopic multi-stage cylinder, the energy accumulator, a motor pump set, a switch valve I and a switch valve II; the motor pump set is connected with the energy accumulator and used for charging oil into the energy accumulator and storing energy; the energy accumulator communicates with a rodless cavity of the synchronous telescopic multi-stage cylinder through the switch valveII, and a rod cavity of the synchronous telescopic multi-stage cylinder communicates with an oil tank through the switch valve I; and oil in the energy accumulator enters the rodless cavity of the synchronous telescopic multi-stage cylinder through the switch valve II, oil in the rod cavity of the synchronous telescopic multi-stage cylinder returns to the oil tank through the switch valve I, thesynchronous telescopic multi-stage cylinder stretches out at a high speed, and therefore high-speed hydraulic erection is achieved.

    本发明公开了一种基于同步伸缩多级缸和蓄能器的高速液压起竖机构,包括:同步伸缩多级缸、蓄能器、电机泵组、开关阀Ⅰ和开关阀Ⅱ;所述电机泵组与蓄能器相连,用于为蓄能器充油蓄能;所述蓄能器通过开关阀Ⅱ与同步伸缩多级缸的无杆腔连通,同步伸缩多级缸的有杆腔通过开关阀Ⅰ与油箱连通;所述蓄能器中的油液经过开关阀Ⅱ进入同步伸缩多级缸的无杆腔,同步伸缩多级缸的有杆腔中的油液经过开关阀Ⅰ回到油箱,使同步伸缩多级缸高速伸出,从而实现高速液压起竖。
