Lift assembly with fire alarm escape function

Abstract

The invention relates to a lift assembly capable of realizing safe escape in case of a fire alarm. At least on lift system is arranged in a building, and is provided with at least one power supply system, an air intake and exhaust switching system, an escape indicating system and an area control center. A sensor arranged in the air intake and exhaust switching system is used for detecting the environmental temperature value and smog detection value of a lift lane and each public space, the power supply system can be switched to a generating set special for the lift system to supply power when a fire alarm is made, and the air intake and exhausting switching system is controlled to supply air forcedly, so that an escaping area is kept in a positive-pressure safe escape ventilated environment; and meanwhile, indications of a safe escape route are provided through a display device, a broadcasting device and an illuminating device of the escape indicating system, so that people can rapidly escape from the fire ground by using the elevator system, and injuries of people are relieved.

Description

technical field [0001] The invention relates to an elevator assembly capable of providing safe escape when a fire occurs, so that when a fire occurs, the elevator system can be used to quickly pick up and transport personnel to escape from the fire scene safely, so as to reduce the damage of personnel. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of a general elevator system. It is equipped with an elevator car 11, a driving host 12, a liftway 13, an air supply motor 14 and a machine room 15. The driving host 12 in the machine room 15 operates to make the elevator The car 11 moves up and down in the liftway 13, and the air supply motor 14 above the elevator car 11 only provides the required air in the elevator car 11 and performs internal circulation. In addition, a row of fans 16 is provided in the machine room 15 for use. In order to discharge the heat generated by the driving host 12 in the machine room 15 to the outside, because the...

[0002] like figure 1 As shown, it is a schematic diagram of a general elevator system. It is equipped with an elevator car 11, a driving host 12, a liftway 13, an air supply motor 14 and a machine room 15. The driving host 12 in the machine room 15 operates to make the elevator The car 11 moves up and down in the liftway 13, and the air supply motor 14 above the elevator car 11 only provides the required air in the elevator car 11 and performs internal circulation. In addition, a row of fans 16 is provided in the machine room 15 for use. In order to discharge the heat generated by the driving host 12 in the machine room 15 to the outside, because the elevator has the convenience of quickly transporting people, but in the event of a fire, based on the safety considerations of fire extinguishing, the power of the building will be quickly consumed. Cut off, so that some tools that could have been transported by elevators to achieve rapid evacuation and escape suddenly became obstacles to escape, and even some people who were originally riding in the elevator were forced to be trapped in the elevator due to power failure and wait for rescue. Or be forced to flee to a dangerous floor; for this reason, general fire prevention education teaches people not to use elevators as a means of escape when a fire breaks out, so that the elevators that could have been used to evacuate people quickly cannot be put to good use.
