Abstract

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.

Description

(1) Technical field: [0001] The invention belongs to the technical field of elevator safety protection, and in particular relates to an elevator safety protection device for preventing accidental movement of a car and a working method thereof. (2) Background technology [0002] In recent years, the elevator market demand has expanded, and the number of elevators to be installed has increased sharply, making the competition in the elevator manufacturing and installation market intensified. However, the frequent elevator safety incidents, Mr. Yan, threaten the lives of users, and the elevator accidents that have been heard from time to time make people terrified. For example, on the evening of September 14, 2014, in the Xiamen campus of Huaqiao University, the elevator in a teaching building suddenly broke down, and a boy was trapped in the car and died. It is reported that the boy was waiting for the elevator on the third floor with his classmates. The door opened but the ca...
