An elevator emergency protection device

Abstract

The invention discloses an elevator emergency protection device. The elevator emergency protection device comprises a working box and a working cavity in the working box, the bottom wall of the working cavity is fixedly provided with a sliding rail, the sliding rail is provided with a first sliding groove which is opened to right, the sliding rail is internally provided with a brake cavity which penetrates through the first sliding groove, the brake cavity is opened to the left, the first sliding groove is internally provided with an elevator box in a sliding manner, the elevator box is internally provided with an elevator cavity, the lower end face of the elevator box is fixedly provided with a sensor box, the sensor box is internally provided with a sensor cavity, and the sensor cavity is internally provided with a sliding plate. The elevator emergency protection device is a protection device designed for the elevator emergency falling, when the elevator is out of control and accelerates the falling, a pawl can be clamped into a ratchet groove, so that the ratchet wheel only rotates in one direction, and the falling speed of the elevator box is delayed; the elevator emergency protection device also ejects a brake plate from the side edge of an elevator shaft, and emergency brake the elevator box through the friction force generated by contacting with the elevator box, the falling speed is slowed down; and an air bag and mechanical braking device are also arranged at the bottom of the elevator shaft so as to provide a relatively stable braking force for the elevator box, so that the falling elevator box is emergently braked and the passengers are protected in the elevator box from danger at the same time.

Description

Technical field [0001] The invention relates to the field of elevator protection equipment, in particular to an elevator emergency protection device. Background technique [0002] Elevator is a kind of vertical elevator powered by a motor, equipped with a box-shaped pod, used for multi-storey buildings to take people or carry goods, and serve the fixed lifting equipment of the specified floor. For vertical lifting elevators, there have been more Most of the accidents were crashing to the ground, causing heavy casualties and causing great suffering to people. There are not many existing elevator safety protection methods. Therefore, there is an urgent need for an elevator emergency protection device to solve the above problems and address the above shortcomings. , The present invention has been improved. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator emergency protection device, which overcomes the above-ment...
