Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to an elevator multiple emergency braking structure. Background Art

[0002] An elevator is a vertical transportation device used to transport people and goods between different floors of a building. The use of elevators has greatly improved the accessibility and efficiency of high-rise buildings, allowing people to easily go up and down floors without having to use stairs. Elevators can transport people from one floor to another quickly and safely. Elevators are essential facilities, especially for high-rise buildings, office buildings, residential buildings, shopping malls, hospitals and other places.

[0003] During the operation of the elevator, due to various reasons, such as power failure, mechanical failure, etc., the elevator may lose control and pose a threat to passengers and equipment. When the elevator braking system is in use, a single braking method is usually adopted, such as electromagnetic braking, hydraulic braking, etc. However, this method has problems such as poor braking effect and long braking time in an emergency. Therefore, we propose an elevator multiple emergency braking structure to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This device can monitor the operating status of the elevator lifting control wheel in real time through monitoring sensors, including key parameters such as speed, position, and power supply. The controller can immediately start the braking program to ensure that the elevator stops running in the shortest time, and start two hydraulic drivers to drive two brake mounting seats, cooperate with the limit slide groove and the limit slider, so that the two brake discs drive the brake anti-skid pads to contact the elevator lifting control wheel, which can ensure that sufficient friction is generated between the elevator lifting control wheel and the elevator lifting control wheel during the braking process, thereby achieving fast and effective braking of the elevator. When a fault occurs, the communication module and the communication adapter can be used to alarm the security management personnel, greatly shortening the time from the occurrence of the fault to the response, so that the security management personnel can take countermeasures as soon as possible.
