Description

Orbital escape ladder

technical field

The utility model relates to a track-type refuge ladder, in particular to a track-type refuge ladder which is erected through the interior or the exterior of a high-rise building.

Background technique

Due to the fact that the cities where humans live are narrow and densely populated and the land prices are becoming more and more expensive, high-rise buildings in urban floors are extremely common. According to the current fire regulations, high-rise buildings must also have safety considerations. Escape equipment as a benchmark! Every once in a while in China, there will always be building fire accidents that cause heavy casualties due to lack of urgency in building escapes. The main cause of serious casualties is mostly insufficient escape measures. The lack of evacuation measures is also to blame. For example, in the recent fire accident in the Carnival Building in Chiayi City, Taiwan, some victims jumped off the building in a hurry because they could not escape. Therefore, how to deal with various unexpected disasters such as: When unwarranted disasters such as fires and earthquakes occur, the escape of residents living on high floors is obviously something that building residents should face up to. Among the current general high-rise building escape equipment, the most commonly used are rope-type vertical landing equipment and escape ladders, and rope-type vertical landing equipment is often difficult to operate because of the shaking caused by climbing, which makes people uncomfortable. Dare to try, it is not suitable for everyone. These devices are especially difficult to provide rapid and safe escape and escape protection for the elderly, the sick, the handicapped and children; Without experience in use, it is often impossible to activate it immediately in an emergency, and in unfamiliar situations, most people do not dare to descend directly into the sky, and a fall accident may occur due to improper operation.

Furthermore, everyone knows that fire and water are ruthless, especially building fires are not uncommon. When a fire occurs, in addition to deadly crises such as flames and thick smoke, the darkness generated by the loss of electricity is another obstacle to escape. It is a big killer, and when the power is lost, the elevator that can quickly take people away from the fire is useless. In view of this, the general fire escape equipment must comply with the principle of no power available, so there are no power escape equipment such as escape slow-down tubes (rescue bags) and slow-down machines. The regulator is used to achieve the effect of emergency escape. Its principle is the same as that of the ancient pulley type ancient well. It uses a pulley device and does a centrifugal force brake to control the descending speed. , throwing, wrapping, bunching, pushing" and other operating formulas, when operating, personnel must hang and slowly lower outside the outer wall of high-rise buildings, and personnel are directly exposed to extremely high environments, which are easily affected by fear of heights and cannot be operated. , On the other hand, the operating procedures and formulas are too complicated, if not well-trained (such as firefighters) can not easily operate, and its personnel escape efficiency is low (only one person operation and use), so the use effect is not good.

In view of the above, the rescue bag is the simplest structure of the escape equipment. It is tied in a high-tensile cloth tube and installed in a proper position with a funnel-shaped loop with an elastic effect. The loop has a slow-down effect, and personnel can quickly get out of the cloth. Drilling and sliding above the pipe to the bottom of the pipe to escape, although the escape efficiency is higher than that of the slow descent machine, it is often limited by the difference in the descending speed caused by the different body shapes and motor nerves of the escapees, which may cause the escapees to collide with each other. On the one hand, if the location of the piping erection is too close to the wall, people may hit the wall and be injured. For those who are inconvenient to move, it is difficult to use rescue bags to escape, so there are still shortcomings in the use of rescue bags.
