Elevator device free of traveling cable and still capable of being used during power outage of building

Abstract

The invention discloses to an elevator device free of a traveling cable and still capable of being used during a power outage of a building and relates to an elevator free of the traveling cable and capable of being used under the condition of the power outage, caused by a fire disaster of the high-rise building or other reasons, of the building. According to the implementation scheme, a rolling wheel which keeps a certain pressure with a guide rail rotates when a car operates to drive a power generator installed on the car to generate power, an accumulator attached to the car is charged, and thus the traveling cable of the car is omitted. A signal detection system is constituted by a landing signal detector on the car, landing externally-calling instruction devices/signal feedback devices installed on landings and signal guiding devices installed at the two ends of a shaft, and an externally-calling floor can be detected. During the power outage, a special cable or a power source of the emergency power generator is automatically switched to be separated from a power source of the building, and normal operation of a computer control cabinet and a driving device is guaranteed. The elevator device can still operate according to instructions of floors and the car during the power outage of the building, and trapped personnel can be helped to evacuate efficiently.

Description

technical field [0001] The invention relates to a non-accompanying cable elevator that can be used when a fire occurs in a high building or a power failure is caused by other reasons. Background technique [0002] There are more and more high-rise buildings and super high-rise buildings in modern cities, but once a fire breaks out, it is difficult for trapped people to evacuate quickly, which is an important cause of casualties. According to current regulations, when a fire breaks out in a building, the power supply should be cut off in time. At the same time, in order to prevent the danger of being trapped in the elevator due to a power failure, the use of ordinary elevators is prohibited. Therefore, the evacuation of trapped people in the building is mainly to escape from the corridor. When escaping through the corridor, in addition to time-consuming and physical exertion, it is easy to cause the danger of corridor blockage and increase the psychological pressure of the ev...

Problems solved by technology

[0003] In order to overcome the drawbacks of the accompanying cables, some manufacturers also use an elevator without accompanying cables such as the application number CN201520524669.0. The secondary coil on the car passes through multiple primary coils fixed on the well wall to generate electricity for the battery. Charging, but the power efficiency generated intermittently is relatively low
