Description

Improved intelligent fire-fighting escape rope ladder

Technical Field

The invention relates to the technical field of fire-fighting products, in particular to an improved intelligent fire-fighting escape rope ladder.

Background

Fire escape rope ladder is used for being locked by the fire between the stair when the high-rise building is on a fire disaster, perhaps the fire fighter puts the escape rope ladder in eminence and rescues the people of danger below, a rope ladder used in emergency escape, because the material of the ladder rope of rope ladder is that vinylon or polypropylene fibre are woven, so this kind of rope ladder can carry out the rolling and fold and leave in the package, very portable, the effect in the actual combat is very showing, although current escape rope ladder is extensive and frequent in the actual combat, but has some problems all the time:

a. because the existing rope ladder is a fixed combination of a ladder rope and ladder steps, the soft body property of the ladder rope determines that the fire-fighting rope ladder is soft, the ladder needs to climb on the rope ladder during use, the climbing needs to be carried out by hands and feet and applies strength to the ladder steps, the rope ladder deforms when the strength is applied, the upper part and the lower part of a part gripped by a hand and including the parts stepped on by the feet can deform to a certain extent, the deformation can prevent a person from applying force on the ladder well, and the deformed ladder can swing during the process of climbing upwards or downwards, so that the feet can not step on the next ladder step accurately quickly during the climbing process, and the ladder is very laborious to use;

b. the rope ladder is especially suitable for high-rise buildings and can be downwards climbed along the ladder after people need to put down the rope ladder along the wall body when the high-rise buildings are in fire, but the width of the ladder step can not be too wide due to the requirement of convenient carrying of the existing rope ladder, and the ladder step is inconvenient to carry if the width of the ladder step is too wide, so the existing ladder step is basically very narrow, but the rope ladder is adhered to the wall body and is added with the narrow ladder step, so that people can only press the wall body to be downwards hooked by the tiptoes in the crawling process, and the mode not only increases the energy and physical strength consumed by escape personnel in the process of escaping, increases the difficulty of escaping, but also greatly reduces the escaping speed of the escape personnel using the escape rope ladder if a plurality of people are trapped, the escaping efficiency of the existing escape rope ladder is very low, and people are known to be very low every minute and second before the disaster situation, therefore, the existing escape ladder is very inconvenient to use.
