Hydraulic excavator, breaking hammer hydraulic system and breaking hammer overflow energy recycling system
The invention discloses a hydraulic excavator, a breaking hammer hydraulic system and a breaking hammer overflow energy recycling system. The breaking hammer overflow energy recycling system comprisesan overflow branch communicated with an oil inlet branch of a breaking hammer; the overflow branch is connected with a third control valve; when the oil pressure in the oil inlet branch is greater than the set overflow pressure, the third control valve is opened; an oil outlet of the third control valve is connected with an energy storage branch; the energy storage branch is connected with an energy storage device and a first control valve; and when the pressure in the energy storage device is larger than the set first energy storage pressure, the first control valve is opened, and the energystorage device supplies energy to a heat dissipation system through the first control valve. According to the hydraulic excavator, the breaking hammer hydraulic system and the breaking hammer overflow energy recycling system, overflow energy can be stored in the energy storage device, the energy storage device can supply energy to the heat dissipation system through the first control valve, the overflow energy of the breaking hammer is recycled to the maximum extent, and the energy utilization rate is increased.
本发明公开了一种液压挖掘机、破碎锤液压系统及破碎锤溢流能量回收利用系统，包括与破碎锤的进油支路连通的溢流支路，所述溢流支路上连接有第三控制阀，当进油支路中的油压大于设定溢流压力时，所述第三控制阀开启；所述第三控制阀的出油口连接有储能支路，所述储能支路上连接有储能器和第一控制阀，当所述储能器中的压力大于设定的第一储能压力时，所述第一控制阀开启，储能器通过第一控制阀为散热系统供能。本发明能够将溢流能量存储于储能器中，储能器能够通过第一控制阀为散热系统供能，最大限度的对破碎锤溢流能量进行回收，提高能量利用率。
