Elevator

Abstract

An elevator is provided with a fire detection device (11) and a fire extinguishing device (12) outside the elevator car (5). The fire detection device (11) is used for detecting the fire and the fire occurrence direction in the lifting passage (1). When the fire detection device detects that a fire has occurred in the elevator passage, the elevator car is avoided in the direction opposite to the fire occurrence direction, and at the same time, the fire extinguishing device sprays fire extinguishing agent in the elevator passage toward the fire occurrence direction. Therefore, the ability to respond to fires in the hoistway can be improved, and the safety of elevator passengers can be further ensured.

Description

technical field [0001] The present invention relates to an elevator, in particular to an elevator with improved response to fires occurring in elevator hoistways. Background technique [0002] The elevator makes the elevator car go up and down in the hoistway provided as an integral part of the building where the elevator is installed. For such an elevator, how to deal with a fire in the elevator (this kind of fire includes both a fire in the elevator and a fire that spreads from the building where the elevator is located) or a fire near the elevator is a problem. [0003] When a fire breaks out near the hoistway, ordinary sprinkler equipment can be used to extinguish the fire. This automatic sprinkler equipment detects the fire by detecting smoke and temperature, and sprays water automatically when a fire is detected. However, when a fire breaks out in the hoistway, the hoistway will form a chimney effect in the fire and be in an ultra-high temperature state. Since ...

Problems solved by technology

Moreover, in the method disclosed in Patent Document 1, since it is necessary to move the fire extinguisher installed near the counterweight to the fire extinguishing location, it takes a certain amount of time to perform the fire extinguishing action, which is not possible from the viewpoint of ensuring the safety of passengers. taken

In addition, in order to extinguish the fire, it is sometimes necessary to bring the elevator car close to the place where the fire broke out, which is not advisable from the perspective of ensuring the safety of passengers.

The processing method of Patent Document 2 also has the same problem in that the safety of elevator passengers cannot be fully guaranteed.

That is to say, in the processing method of Patent Document 2, when a fire breaks out in the elevator pit, it is necessary to make the elevator car face to the side of the elevator pit where the fire occurs, so the safety of elevator passengers cannot be fully guaranteed.
