AI Technical Summary

Problems solved by technology

However, an error in any part of the system or failure of components may lead to the paralysis of the entire anti-fall system. force, but the effect is limited, and it may still cause casualties to the occupants in the elevator
Although the vertical elevator has been equipped with the above two anti-fall protection devices, it still cannot completely avoid the occurrence of elevator falling accidents.

Abstract

The invention discloses a sudden stop control device used during falling of an elevator. The sudden stop control device comprises a first sensor, a sudden stop button, a locking device and a controller. The first sensor and the sudden stop button are arranged in a lift car. The locking device and the controller are arranged on a car top frame. One end of the controller and the first sensor are connected mutually. The other end of the controller and a contactor are connected mutually. A control loop controlling action of the locking device comprises the sudden stop button and the contactor which are connected mutually. According to the design, a brake device completely independent of an existing fall-prevention system is additionally arranged so that a passenger can control braking of the elevator through the sudden stop button in the lift car of the elevator. In addition, through detection of the sensor, after falling speed is continuously higher than a set value and exceeds certain time, the controller gives out an order, and braking of the elevator is conducted. The dual-protection brake device is safer and more reliable.

Description

technical field [0001] The invention relates to a vertical elevator, in particular to an emergency stop control device used when the elevator falls. Background technique [0002] In recent years, with the advancement of urbanization and the improvement of residents' living standards, elevators have become an indispensable means of vertical transportation in people's production and life. In order to ensure safe operation, general vertical elevators are equipped with anti-falling devices. Gear, safety gear and the buffer at the bottom of the hoistway and other devices to achieve. Once the elevator is found to be descending at an overspeed, the speed limiter will first stop the elevator driving the main engine. If the main engine still does not stop, the speed limiter will lift the safety gear to clamp the locking device guide rail, forcing the car to stop on the locking device guide rail. In addition, if it directly hits the buffer within a certain speed, the car will also st...
