The invention discloses a hydraulic automatic coupler lifting device for an empty car shunting machine and a control method. The device comprises a coupler lifting control mechanism and a positioning detection mechanism, wherein the coupler lifting control mechanism is composed of a coupler lifting mechanism and a coupler lifting hydraulic control system, and the positioning detection mechanism comprises a coupler opening in-place proximity switch, a coupler closing in-place proximity switch, a coupler lifting in-place proximity switch and induction stop iron. During working, control over lifting and dropping of a car coupler is achieved through a PLC system by acquiring induction signals, under different working conditions, of a coupler opening in-place switch, a coupler closing in-place switch, a coupler lifting in-place switch, a car pushing starting point switch, a car pushing speed reduction position switch and a car pushing terminal point switch of an empty car shunting machine hook head, and automatic and steady coupler touching and removal of the empty car shunting machine are achieved. The problem of direct collision between the empty car shunting machine hook head and a compartment is solved, and operation safety is improved. The reliability of equipment is ensured, and the damage rate of equipment is reduced.
