Anti-falling rescue elevator

Abstract

The invention relates to an anti-falling rescue elevator, comprising a car, a car door arranged at the front part of the car and driven by a door opening machine, and a landing door arranged on a corresponding floor, wherein a bottom cabin and a top cabin are separated out at the bottom and the top of the car respectively by virtue a lower clapboard and an upper clapboard; a bottom detecting plate and a top detecting plate, which are driven by a power mechanism and can hang out of the cabins, are arranged in the bottom cabin and the top cabin respectively; a bottom tank and a top tank are arranged at the bottom and the top of the floor respectively; the car door is a two-leaf center opening door; a car door rack is arranged at the inner side of the bottom end and the inner side of the top end of each leaf of the car door respectively; a vertical rotating shaft is arranged rotationally in the car; a driving gear engaged with the car door rack is arranged at each of the top and the bottom of the rotating shaft; a driven gear in linkage with the driving gear is also arranged on the rotating shaft; the detecting plates are arranged in the cabins in a sliding manner by virtue of sliding rails; and detecting plate racks engaged with the driven gears on the two sides are arranged on two sides of the detecting plates respectively. The anti-falling rescue elevator has the advantages of simple structure, safety and reliability in use, and capability of effectively avoiding elevator accidents.

Description

technical field [0001] The invention relates to the field of safety protection of elevators, in particular to an anti-fall lifesaving elevator. Background technique [0002] Elevator mainly includes hoistway, car, lifting drive system and electrical control system. In addition, landing doors, floor buttons and floor displays are also set on each floor. Wherein, guide rails are installed vertically on two opposite inner side walls of the hoistway, and the car is installed on the car frame, and both sides of the car frame are slidably installed on the guide rails through elastic guide shoes. The lifting drive mechanism generally includes a traction machine, a reducer, a wire rope, a sheave assembly and a counterweight. One end of the wire rope is connected to the top of the car, the wire rope goes around each sheave, and the other end is connected to the counterweight. The car is equipped with a door on the side opposite to the landing door. The door is generally split in the...

Problems solved by technology

Although there are many safety protection measures for elevators, elevator accidents still occur frequently, and the existing protective measures cannot fundamentally solve the problem. Elevator accidents have caused great harm and psychological burden to people.

The traditional elevator brake system often fails, causing the car to fall suddenly, or the control system failure, causing the elevator to rise suddenly, and the sudden fall or rise will bring great danger to the passengers in the car or passengers entering or leaving the car.
