Self-escaping apparatus

Abstract

The invention provides a self-escape device, mainly comprising a manual cable which is arranged at a window of an elevator cage, and is linked with a manual wheel, wherein, the manual wheel drives a first mandrel and a first driving wheel; a brake block is driven by the first mandrel to force a brake device to generate actions of brake, release, brake and release, so lifting and descending of an elevator make intermittent shift motion; the first driving wheel is in engaging transmission with a second driving wheel of a second mandrel; the second mandrel is provided with an intermittent driving wheel to stir a driving wheel which is sleeved with a lift cable so as to lose the balanced state of the elevator cage, thereby achieving the aim of self escape by the lifting and descending of the elevator, and preventing a stall risk.

Description

technical field [0001] The present invention relates to a self-extrication device, especially technically providing trapped elevator personnel with self-rescue and self-rescue. It is mainly equipped with a manual cable-driven brake to generate intermittent braking action, and at the same time, the intermittent driving wheel is toggled to make the elevator go up or down. . Background technique [0002] refer to figure 1 As shown, it is a schematic plan view of an existing elevator. The existing elevator includes a motor 1 to drive a driving wheel 2 to rotate, and the driving wheel 2 is provided with an elevator cable 3 so that when the driving wheel 2 rotates, the cable pulls or and the elevator can go up and down; in addition, a brake 4 is installed between the motor 1 and the driving wheel 2. The main function of the brake 4 is that the brake 4 can stop the motor 1 and the driving wheel 2 when the elevator operates abnormally. , to prevent the elevator from stalling and f...

AI Technical Summary

Problems solved by technology

[0004] 1. It is impossible for professionals to be on standby in the machine room of each elevator at any time. Therefore, when an elevator with an elevator breaks down and the car is not aligned with the floor level, it is necessary to contact the professionals urgently and wait for the professionals to arrive before they can operate and release the elevator. The brakes are in a stopped state, so it is not suitable for people trapped in a small space to wait, and it is also dangerous

[0005] 2. Professionals release the brakes to make the elevator go up and down and get out of trouble. The principle is that the elevator and the counterweight are in an unbalanced state, so when the brake is released, the unbalanced elevator and the counterweight will move. If the elevator is balanced with the counterweight and the elevator is not aligned with the floor, even professionals will be helpless to deal with it, because the elevator will not be able to work if it is in a balanced state. verb: move

However, it still requires professionals to enter the computer room to control it, and it cannot achieve the purpose of self-rescue
