Description
Technical Field
[0001] The utility model belongs to the technical field of fire fighting equipment, in particular to a fire fighting self-rescue ladder. Background Art
[0002] When a fire accident occurs, more deaths are not caused by direct burning to death by fire, but by the consumption of oxygen in the combustion process, and a large amount of toxic substances are produced during the combustion process. Therefore, the smoke in the fire is sometimes in a low-oxygen toxic state, and inhalation of this smoke causes hypoxia, which can cause death. Fire rescue is timely, but with the development of construction technology, more and more high-rise buildings are rising from the ground, and the incidence of high-rise building fire accidents is increasing year by year. Since high-rise buildings have high floors, once the fire occurs on the high floors, from the perspective of outdoor attack alone, except for outdoor stairs, climbing platform fire trucks, ladder fire trucks and existing 15-meter metal ladders cannot reach the rescue floor. There are also a large number of bungalow courtyards composed of house buildings in the city. These bungalow courtyards are characterized by dense courtyards, low fire resistance levels, and narrow alleys. Especially at night, the phenomenon of private cars occupying the road for parking is serious. Once a fire occurs, it is difficult for fire trucks to enter, resulting in the inability to carry out rescue in time. Therefore, residents trapped by the fire should find ways to save themselves. There are currently two commonly used fire self-rescue ladders, one is a rope ladder, and the other is a hook-type telescopic ladder. When using a rope ladder for self-rescue, if the user has not received professional training, it is more likely to cause accidents. When using a hook-type telescopic ladder for self-rescue, the hook of the hook-type telescopic ladder may not have a general hooking effect when hooking to the wall. At that time, the ladder is easy to shake, and the safety performance is reduced. At the same time, the hooking will be unstable, resulting in more serious safety accidents. Utility Model Content
