Energy recovery system of excavator
The invention discloses an energy recovery system of an excavator in the technical field of additional modification of excavators, and aims to solve the problems of complicated assembly and poor energy-saving efficiency and safety of the energy recovery system of the excavator in the prior art. The method comprises the steps that when an excavator working arm descends, an energy storage device is charged through a traction machine, the excavator working arm ascends, the energy storage device releases energy, the traction machine assists the excavator working arm in ascending, and a mounting support and a traction rope are directly connected with an external machine body and the working arm of the excavator, so that the energy recovery system is easy to assemble and low in cost. The modification or design of a broad axe for the excavator is not needed, and the existing excavator can be additionally mounted; the energy recovery system of the excavator circularly utilizes gravitational potential energy of the working arm, the energy-saving effect is high, descending of the working arm can be buffered through the traction rope when the movable arm oil cylinder fails or is broken, the energy recovery system of the excavator is basically arranged externally, direct influence on a hydraulic system of the excavator is avoided, and the overall stability of the excavator is guaranteed.
本发明公开了一种挖掘机附加改装技术领域的挖掘机的能量回收系统，旨在解决现有技术中挖掘机的能量回收系统装配复杂、节能效率和安全性差的问题。其包括：挖掘机工作臂下降时通过曳引机向蓄能装置充能，挖掘机工作臂上升蓄能装置放能实现曳引机辅助挖掘机工作臂的上升，安装支架与曳引绳直接与挖掘机的外部机体和工作臂连接，因此能量回收系统的装配简单，不需要对挖掘机进行大刀阔斧的改装或设计，可对已有的挖掘机进行加装；挖掘机的能量回收系统循环利用工作臂的重力势能，节能效果高，且当动臂油缸失效或折断时曳引绳可缓冲工作臂的下降，且挖掘机的能量回收系统基本外置，不对挖掘机本身的液压系统造成直接影响，保障了挖掘机整机稳定性。
