Problems solved by technology

There are many reasons for non-human intentional movement, for example, when the elevator stops at the normal landing state, the brake is suddenly opened and the elevator runs; in the normal state, the conventional brake fails, the elevator starts unexpectedly or overspeed; Unintentional movement of the elevator car will threaten the lives of passengers and cause serious safety accidents.

Embodiment Construction

[0015] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] see figure 1 As shown, the elevator safety brake device includes a trigger unit 2 , a control unit 3 and a brake 4 . The trigger unit 1 is a self-monitoring electronic detection device with redundant circuit design, or an electromechanical trigger device, which can detect the movement of the elevator car 1 and then send a trigger signal. The control unit 3 is connected to the trigger unit 1, and the control unit 3 It can receive the trigger signal sent by the trigger unit 1 and then judge and analyze it so that the brake signal is sent when the car 1 moves unintentionally. The brake 4 is an electromechanical brake. The brake 4 is connected to the control unit 3 and can receive the control unit. The brake signal sent by 3 then brakes the traction sheave of the elevator by braking the brake disc coaxially fixed with the traction sheave, so t...

Abstract

The invention discloses an elevator safety braking device, which includes a trigger unit, a control unit and a brake. The car of the elevator is always kept in a detected state. When the car moves, the trigger unit sends a trigger signal, and the control unit receives the trigger signal and Analyze and judge it, if the result of the analysis is that the movement of the car is the normal operation of the elevator or the detection state, etc., the brake signal will not be issued, and the brake is open at this time; if the result of the analysis is that the car When the movement of the car is unintentional, the control unit sends a braking signal to the brake, and the brake stops the traction sheave of the elevator, and the elevator stops running. The elevator safety braking device is safe and reliable, avoids safety accidents caused by abnormal movement of the elevator car, and ensures the safety of passengers.

Description

[0001] technical field [0002] The invention relates to an elevator safety braking device. [0003] Background technique [0004] With the development of elevator technology, the safety of elevators has been gradually improved, but in daily life, elevator failures and safety accidents caused by non-human intentional movement still often occur. There are many reasons for non-human intentional movement, for example, when the elevator stops at the normal landing state, the brake is suddenly opened and the elevator runs; in the normal state, the conventional brake fails, the elevator starts unexpectedly or overspeed; Unintentional movement of the elevator car will threaten the lives of passengers and cause serious safety accidents. [0005] Contents of the invention [0006] The object of the present invention is to provide a safety brake device that the elevator car will be stopped when it is moved unintentionally. [0007] In order to achieve the above object, the tech...
