Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a hoistway type elevator self-rescue device and a method for operating the self-rescue device. Background technique [0002] According to building regulations, high-rise buildings with seven floors or more, such as residential buildings and office buildings, should be equipped with elevators. This kind of hoistway elevator is usually installed in residential or office buildings, and is mainly used for the transportation of people or goods between floors in the vertical direction.

As for the elevator, which is a necessary means of transportation for people to travel, while the elevator provides convenient services for people, the problem of elevator failure and trapped people is a safety hazar...

AI Technical Summary

Problems solved by technology

However, when the elevator encounters a fault during operation, such as a power outage, or other faults that cause the protective brake of the traction machine, etc., the elevator car is likely to stop suddenly in the non-leveling area of ​​the elevator shaft, that is, to stay between floors

The consequences of elevator failure are usually: people trapped in the car can only wait for the elevator professionals to come to the rescue, and cannot rescue themselves

If the people inside the car cannot get in touch with the outside rescuers, it often leads to the untimely rescue of the outside people, which causes a great safety hazard to the elevator occupants. Secondly, even if the people inside the car open the car door to save themselves, because the car Staying between floors, the elevator crew faces the well, and it is easy to fall and cause personal injury accidents
