The invention discloses an elevator safety protection device for preventing a cage from accidental movement and a working method of the elevator safety protection device. The device comprises a pair of biaxial ball screw rail sliding tables, a pair of square steel, a pair of protective covers, a pair of control switches, a stepper motor driver and a motor controller. The working method of the device comprises the following steps that an elevator is prepared for receiving passengers, the square steel extends outwards, a cage door and a leveling door can be opened, then the cage is suppressed to move by the steel square, and after the cage door is closed, the square steel retracts, and the cage door and the leveling door cannot be opened. The device and the working method have the advantages that the condition that the cage accidentally moves in a leveling area can be effectively avoided, reliable performance, convenience in maintenance and low cost are achieved, potential safety hazards caused by the elevator to the passengers are reduced, and the safety of the elevator is improved.
