Electromagnetic protection safe elevator

Abstract

The invention discloses an electromagnetic protection safe elevator. The elevator comprises an elevator shaft and an elevator car. The bottom end of the elevator shaft is provided with a first electromagnetic device which is provided with a pressure sensor and triggered by a first distance sensor. The bottom end of the elevator car is provided with a second electromagnetic device triggered by a second distance sensor. Electromagnetic fields generated in the first electromagnetic device and in the second electromagnetic device are same in magnetic pole. ABS brake rail devices are fixedly connected to the two sides of the top end of the elevator car. The top end of the elevator shaft is fixedly connected with a storage battery and an automatic control box with a controller. Through the second electromagnetic device and the first electromagnetic device, the situation that the elevator car accidental falls and injures people is avoided, the first electromagnetic device of the elevator bodyand a first electromagnetic device on the ground simultaneously generate strong homopolar electromagnetism, the same electromagnetic poles repel mutually, thus, the elevator car is protected, throughthe ABS brake rail devices, the function of the ABS brake rail devices is automatically triggered when the elevator car falls due to sudden cable breakage, and thus the safety of the elevator car isensured.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an electromagnetic chemical-proof safety elevator. Background technique [0002] With the development of the economy and the progress of society, most of the cities are high-rise buildings, so the elevator has become one of the necessary equipment for urban development. Traditional elevators have also designed multi-level safety protection measures to reduce the probability of elevator falling accidents. , but the effect is a drop in the bucket, and it cannot actually solve the problem of elevator falling, and elevator falling incidents are also common. [0003] But when the elevator of present high-rise building falls, the gravitational acceleration is relatively large. Therefore, so many accidents caused by elevator falls are not caused by unqualified elevators, but by failure of safety technology. It can enter the elevator box, and then affect the air in the elevator box. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of elevator accidents in high floors in the prior art. Under multi-level measures, safety accidents often occur, and air circulation cannot be realized in some elevator casings, or skylights are provided in some elevator casings, so dust directly enters. In the inner cavity of the elevator box, it will affect the air in the elevator box and other shortcomings, and a kind of electromagnetic anti-chemical safety elevator proposed
