The invention discloses a double-engine hydraulic system which comprises an upper hydraulic system, a lower hydraulic system and a lower oil supply system and further comprises a conversion module enabling the lower oil supply system to supply oil to the upper hydraulic system, and the conversion module comprises a first connecting valve and a second connecting valve. The first connecting valve is connected with the lower vehicle oil supply system and the lower vehicle hydraulic system, and the second connecting valve is connected with the lower vehicle oil supply system and the upper vehicle hydraulic system. When the control valve selects the first connecting valve to be communicated, the lower vehicle supplies oil to the lower vehicle normally, and when the control valve selects the second connecting valve to be communicated, the lower vehicle supplies oil to the upper vehicle, the lower vehicle is combined to the upper vehicle and supplies oil to the upper vehicle, flow limitation is broken through, and the operation speed of the upper vehicle is increased.

    本发明公开了一种双发动机液压系统,包括上车液压系统、下车液压系统以及下车供油系统,还包括使下车供油系统为上车液压系统供油的转换模块,所述转换模块包括第一连接阀和第二连接阀,以及选择第一连接阀或第二连接阀连通的控制阀,第一连接阀连接下车供油系统和下车液压系统,第二连接阀连接下车供油系统和上车液压系统。控制阀选择第一连接阀连通时,下车正常为下车供油,选择第二连接阀连通时,下车为上车供油,下车合并至上车,为上车供油,突破流量限制,提高上车作业速度。
