The invention relates to the technical field of hydraulic elevators, and provides a hydraulic elevator safety protection device and a safety protection method.The hydraulic elevator safety protection device comprises a hydraulic oil cylinder and a plunger and further comprises a stand column arranged in a hoistway and an accompanying gear rotationally arranged on the outer wall of a lift car through a rotating seat, and a rack is arranged on the side, close to the lift car, of the stand column; the following gear is meshed with the rack, the speed limiter is arranged on the lift car, the inertia locking assemblies are used for locking the lift car when the lift car falls, the clamping mechanisms correspond to the inertia locking assemblies in a one-to-one mode and are used for driving the inertia rotating rod to clamp the stand column, and the anti-deviation assembly comprises a limiting sliding sleeve. The elevator shaft is arranged on the outer wall of the lift car, and the limiting rod is arranged in the elevator shaft. By means of the technical scheme, the problems that in the prior art, a hydraulic elevator is not provided with a safety protection device, potential safety hazards exist, and deflection of the lift car is inconvenient to prevent are solved.
