Description

Emergency self-propelled refuge ladder structure

Technical Field

The invention relates to an emergency self-propelled refuge ladder structure, in particular to a self-propelled refuge ladder which is erected inside or outside a high building in a penetrating way.

Background

Since the city where people live is narrow in land, thick in land and expensive in land price, the high-rise buildings are very common in the city floors, and the high-rise buildings according to the current fire regulations must have escape equipment for safety consideration! The main reason that the death and injury are serious is mostly the shortage of escape measures because the building fire accident that the death and injury are disastrous because the escape of the building is not urgent always occurs at intervals; in addition to the fact that public safety inspection cannot be completely implemented, the escape measures of the building itself are insufficient and difficult to blame, for example, a recent fire accident occurring in the jianianhua building in jiayi city, and some victims have lost their lives because they cannot escape and avoid the building, so how to cope with various unexpected disasters such as: when disasters without early warning, such as fire, earthquake, and the like, occur, the escape problem of the accommodation personnel living in the high floor is obviously the person who is supposed to be looked at by the residents in the big building. The rope type vertical landing equipment and the escape ladder are the most commonly used in the existing common high-rise building escape equipment, and the rope type vertical landing equipment is not easy to operate and is not easy to try due to shaking generated in climbing and hanging, so that the rope type vertical landing equipment is not suitable for all people, and the device is particularly difficult to provide rapid guarantee for safe escape and escape for old people, patients, mobility-handicapped people and children; in fact, the general people do not have experience in using the vertical falling escape device, the vertical falling escape device cannot be used immediately in case of emergency, and most people are afraid of falling to high altitude directly in unfamiliar situations, and a falling accident with improper operation can also occur.

Furthermore, people know that water and fire are inexistent, particularly, the fire accident of buildings is more frequent, when the fire happens, in addition to the fatal crisis of flame, dense smoke and the like, the darkness generated after the power is lost is a big killer for preventing escape, and when the power is lost, people can be quickly taken away from the electric ladder of the fire scene and the electric ladder is the same as the nominal ladder. In view of this, general fire-fighting escape equipment must meet the principle of no electric power available, so there are some escape slow-descent pipes (rescue bags) and slow-descent machines, etc., wherein the slow-descent machines are internally provided with deceleration regulators to achieve the effect of emergency escape, the principle is the same as that of ancient pulley-type old wells, and the slow-descent machines are controlled by using pulley devices and performing centrifugal force braking to control the descent speed, the equipment cost is low, but the operation is complicated, and the operating tables such as "hanging, losing, sleeving, binding, pushing" must be remembered, when in operation, the personnel must hang and slowly descend outside the outer wall of a high-rise building, the personnel are directly exposed to the extremely high environment, and the high-fear influence is easily generated, on the other hand, the operation program and tables are too complicated, if the personnel who are not trained (such as firefighters) can not easily operate, and the personnel escape efficiency is low (only one person is operating), so the use effect is poor.

In view of the above, the escape apparatus is the simplest in structure of the rescue bag, and is a funnel-shaped girdle with an elastic effect arranged at a proper position in a high tensile resistance distribution pipe, and the girdle has a slow descending effect, so that people can quickly slide to the lower part of the distribution pipe from the upper part of the distribution pipe for escape. For the evacuees who are inconvenient to move, the difficulty of using the rescue bag for escape is high, so the rescue bag still has defects in use.
