[0024] Such as figure 1 As shown, the elevator self-rescue system of this embodiment includes a synchronous motor 1 , a brake 2 , a brake coil 3 , a button 4 , a fault detector 5 , a normally open contact 6 and a shorting unit 10 .

[0025] Wherein the synchronous motor 1 is electrically connected to the short-circuit unit 10 through the normally open contact 6, the short-circuit unit 10 is used to short-circuit the motor, and the brake coil 3 is connected to the brake 2 is connected and when the brake coil 3 is turned on, the brake 2 is opened, and the elevator car starts to move, otherwise the brake 2 brakes the elevator car, and the elevator is in a static state. In this embodiment, the release action of the brake 2 is realized by controlling the brake coil in the brake 2 .

[0026] The brake coil 3 is also connected to the button 4. When the user presses the button 4, the button 4 is connected to the brake coil 3, and the formed loop makes the brake coil 3 also conduct. ...

no. 2 example

[0038] Such as figure 2 As shown, the difference between this embodiment and the first embodiment is that the elevator self-rescue system in this embodiment also includes a normally open contact 7, and the normally open contact 7 is connected in series with the brake coil 3 and the button between 4.

[0039] Wherein when the elevator fails, the fault detector 5 also closes the normally open contact 7 , so that a path is formed between the brake coil 3 and the button 4 . At this time, the user can make the conduction between the button 4 and the brake coil 3 to release the brake 2, so that the elevator car enters the leveling area, so it is convenient for the user to save himself.

[0040] In this embodiment, the brake coil 3 and the button 4 are isolated by the normally open contact 7, so as to prevent the user from misoperation when the elevator is in normal operation, that is, when the elevator is in normal operation, the user cannot control it through the button 4 The br...

[0042] Such as image 3 As shown, the difference between this embodiment and the second embodiment is that the elevator self-rescue system in this embodiment also includes a displacement detector 8, and the displacement detector is used to detect whether the car of the elevator reaches the bottom of the elevator shaft or top.

[0043] In this embodiment, the displacement detector 8 is arranged between the normally open contact 7 and the brake coil 3. In addition, the user can also connect the displacement detector 8 with other components according to the design and structure of the elevator system. For example, the displacement detector 8 is arranged between the normally open contact 7 and the key 4 and the like.

[0044] Wherein when the elevator fails, when the displacement detector 8 does not detect that the car of the elevator reaches the bottom or the top of the elevator shaft, the conduction between the brake coil 3 and the displacement detector 8, so the brake coil 3 ...

Abstract

The invention discloses an elevator self-help system which comprises a motor and a band-type brake used for an elevator system, wherein the motor is used for driving a lift car; the band-type brake is used for braking the lift car; the elevator self-help system also comprises a short circuit unit, a band-type brake releasing unit, a band-type brake controlling unit, a first normally open contact unit and a fault detection unit, wherein the motor is electrically connected with the short circuit unit through the first normally open contact unit; the short circuit unit is used for connecting the motor in short circuit; the band-type brake controlling unit is electrically connected with the band-type brake releasing unit and is used for controlling the band-type brake releasing unit to release the band-type brake; and the fault detection unit is used for controlling the closing and opening of the first normally open contact unit through detecting whether the elevator system breaks down or not. The elevator system in the invention enables a user to control the elevator to descend to the bottom of an elevator shaft leveling zone, thereby enabling the user to rapidly escape from predicament.

Description

technical field [0001] The invention relates to an elevator self-rescue system, in particular to a self-rescue system for trapped persons when an elevator fails. Background technique [0002] When an elevator on the existing market breaks down, the elevator may stop at the non-leveling area in the elevator shaft and cannot operate. At this time, it is usually necessary for professional elevator maintenance personnel to rush to the accident elevator to carry out rescue after being notified. The process of maintenance personnel often needs to last for 30 minutes to 1 hour, thus causing great psychological adverse effects on the trapped passengers. [0003] Especially when a home elevator breaks down, since the elevator is located in the user's home, once the elevator fails and people are trapped, rescuers have to break in or contact the relevant family members to open the door, which causes great inconvenience to rescue and maintenance work. [0004] In addition, if the trapp...
