A fire elevator with escape device

Abstract

The invention discloses a fire elevator with an escape device. The fire elevator comprises a fire elevator body. An escape cavity is formed in the back of the fire elevator body. An electric retractable door is mounted on the rear portion of the fire elevator body. A fixed rod is mounted on the top of the escape cavity. The outer sidewall of the fixed rod is rotatably provided with a driving rotary shaft. A first bevel gear is rotatably mounted on the driving rotary shaft. An electromagnetic brake is mounted at the end of the driving rotary shaft. A generator is mounted in the escape cavity through connecting rods. A second bevel gear is engaged with the output end of the generator. The fire elevator is simple in structure, ingenious in design and convenient to use. By adopting the fire elevator with the escape device, passengers in an elevator car can escape quickly when the elevator car drops in case of a failure or gets stuck in an elevator shaft or an elevator door cannot be opened due to a power failure of the elevator because of a fire. Accordingly, the safety of firefighters carrying out fire extinguishment through the fire elevator in case of the fire is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting elevator equipment, in particular to a fire-fighting elevator with an escape device. Background technique [0002] The fire elevator is an elevator that is used by firefighters for fire fighting and rescue when a fire breaks out in a building and has certain functions. Therefore, fire elevators have high fire protection requirements, and their fire protection design is very important. At present, in mainland China, firefighter elevators in the true sense are very rare. The so-called "firefighter elevators" we see now are only ordinary passenger elevators with the function of returning to the preset base station or evacuation floor when the fire switch is activated. At present, with the increase of high-rise buildings, in the process of fire extinguishing and rescue of high-rise buildings, in order to improve the efficiency of firefighters' fire extinguishing work and improve the evacuation ...

Problems solved by technology

At present, in mainland China, firefighter elevators in the true sense are very rare. The so-called "firefighter elevators" we see now are only ordinary passenger elevators with the function of returning to the preset base station or evacuation floor when the fire switch is activated. At present, with the increase of high-rise buildings, in the process of fire extinguishing and rescue of high-rise buildings, in order to improve the efficiency of firefighters' fire extinguishing work and improve the evacuation of people in the fire scene, buildings are often equipped with dedicated fire-fighting equipment. However, since the fire elevator is often used when a fire breaks out, it is very easy to cause the fire elevator to malfunction due to fire, and even cause the car to fall or get stuck in the elevator shaft, seriously threatening the inside of the car The life safety of firefighters, and when these problems occur in the current elevator, the personnel cannot save themselves. In view of the above problems, a fire elevator with an escape device is proposed.
