Potential energy recovery system for single auxiliary boom cylinder of excavator
The invention discloses a potential energy recovery system for single auxiliary movable arm oil cylinders of an excavator. The potential energy recovery system comprises an oil tank, a hydraulic pump, a main control valve group, two main control oil cylinders, an auxiliary oil cylinder and an energy storage device, the oil tank communicates with the hydraulic pump; the hydraulic pump is communicated with rod cavities and rodless cavities of the two main control oil cylinders through the main control valve group; the hydraulic pump is further communicated with a rod cavity and a rodless cavity of the auxiliary oil cylinder through the main control valve set. The energy storage device is communicated with a rodless cavity of the auxiliary oil cylinder; when a movable arm of the excavator descends, hydraulic oil in a rodless cavity of the auxiliary oil cylinder flows into the energy storage device for energy storage; when a movable arm of the excavator ascends, hydraulic oil of the energy storage device flows into a rodless cavity of the auxiliary oil cylinder under the pushing of high-pressure gas to push a cylinder rod of the auxiliary oil cylinder to ascend to release energy.
本发明公开了一种挖掘机单辅助动臂油缸势能回收系统，包含一油箱、一液压泵、一主控制阀组、二主控油缸、一辅助油缸及一蓄能装置；油箱连通于液压泵；液压泵通过主控制阀组连通于二主控油缸的有杆腔及无杆腔；液压泵还通过主控制阀组连通于辅助油缸的有杆腔及无杆腔；蓄能装置连通于辅助油缸的无杆腔；其中，当挖掘机的动臂下降，辅助油缸的无杆腔内的液压油流入蓄能装置进行储能；当挖掘机的动臂上升，蓄能装置的液压油在高压气体推动下流入辅助油缸的无杆腔推动辅助油缸的缸杆上升进行放能。
