Abstract

The invention discloses a hydraulic oil way for gantry lifting and potential energy recovery of an electric empty box stacking machine. The hydraulic oil way comprises a working connector for communicating with a working cavity of a working oil cylinder; a forward-reverse rotation oil pump; a main motor in mechanical transmission connection with the forward-reverse rotation oil pump so as to drive the forward-reverse rotation oil pump to work in an electric mode to supply oil, and return oil to drive the forward-reverse rotation oil pump to rotate in a power generation mode to generate power; an auxiliary oil pump; an auxiliary motor for driving the auxiliary oil pump to work to supply oil; and a hydraulic control proportional valve, wherein one side of the hydraulic control proportional valve communicates with the working connector, the other side of the hydraulic control proportional valve communicates with a port in one side of a first control switch valve set, and communicates with an oil tank through a second control switch valve set, a port in the other side of the first control switch valve set communicates with the forward-reverse rotation oil pump, and communicates with the auxiliary oil pump through a first one-way valve, and therefore the auxiliary oil pump can supply oil to the first control switch valve set. The problem that energy is not convenient to recover during oil return of an existing working oil cylinder can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, and more specifically relates to a hydraulic oil circuit for lifting the mast of an electric empty container stacker and recovering potential energy. Background technique [0002] The current gantry of the empty container stacker can reach a higher position, and its potential energy is also higher at the high position, and it is considerable to recover this part of energy. When the mast is lowered, the pressure oil drives the hydraulic motor to rotate, and the hydraulic motor drives the generator to rotate, thereby realizing potential energy recovery. [0003] It is more in line with the production practice to perform potential energy recovery when the mast of the empty container stacker is at a higher position. However, when the mast is at a lower position to recover potential energy, the recovered potential energy will not be able to meet the consumption of generator rotation, thus c...
