Description

A high-rise building escape device

Technical field:

The utility model relates to the technical field of escape self-rescue equipment, in particular to a high-rise building escape equipment.

Background technique:

With the development of economy and society, more and more high-rise buildings are used for living or working, which makes the living and working environment of the population denser year by year. In the face of more and more residential buildings and office buildings over 50 meters and 100 meters in the city, once a fire occurs, the firefighting can only rely on the fire-extinguishing ability of the building itself, and self-rescue basically depends on ourselves. Especially when the danger occurred on a higher floor, the fire ladder was difficult to be used for the evacuation of personnel. According to the news, it is very limited to equip fire-fighting aerial ladders exceeding 50 meters in medium-sized or developed cities at present. When there is a fire or other dangerous situations, it will bring great danger to people living or working in high-rise buildings, often causing a large number of casualties.

Traditional escape equipment for high-rise buildings is generally driven by a motor. The descent speed of the escape safety rope depends on the speed of the motor, and there is no speed limiting device. When the motor fails or is damaged, it is easy to cause the safety rope to stall. Casualties.

Utility model content:

The purpose of this utility model is to provide a high-rise building escape device for the defects and deficiencies of the prior art. It has a simple structure and a novel design. It adopts the cooperation of the speed-limiting chuck and the locking device, which can well ensure the safety of escape. To avoid damage to the motor and cause the rope to stall.

In order to solve the problems existing in the background technology, a high-rise building escape device of the present utility model includes a slow-down lifesaving device, a rope winding driving wheel, a guide wheel, a speed-limiting slow-down wheel, a first speed-limiting chuck, a rotating speed Detection wheel, locking key, second speed-limiting chuck, buffer spring, lead-out wheel; the internal left side of the slow-down lifesaving device is provided with a rope winding drive wheel, and the rope on the rope winding drive wheel passes through the guide wheel Cooperate with winding on the speed-limiting slow-down wheel, the speed-limiting slow-down wheel is set on the right side of the rope winding drive wheel; the left side of the speed-limiting slow-down wheel is provided with a first speed-limiting chuck, the first speed-limiting chuck The left side is connected with a speed detection wheel, the speed detection wheel meshes with the rope winding drive wheel, and the speed detection wheel is connected with the locking key, and the locking key is arranged at the lower end of the speed limiting slow down wheel; the second speed limiting The chuck is arranged on the right side of the speed-limiting slow-down wheel, and the inner side of the second speed-limiting chuck is provided with a buffer spring; the right side of the slow-down lifesaving device is provided with a lead-out wheel.

Preferably, the ropes wound on the speed-limiting slow-descent wheel are distributed in a cross structure.

Preferably, the first speed-limiting chuck and the second speed-limiting chuck have a herringbone structure, and rubber rollers are provided at both ends to mesh with the speed-limiting slow-down wheels.

Compared with the prior art, the utility model has the advantages of simple structure, novel design, and the cooperation of the speed-limiting chuck and the locking device, which can well ensure the safety of escape and avoid the rope stall caused by motor damage .

detailed description:

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, this specific embodiment adopts the following technical scheme: it includes a slow-down lifesaving device 1, a rope winding drive wheel 2, a guide wheel 3, a speed-limiting slow-down wheel 4, a first speed-limiting chuck 5, a rotating speed Detection wheel 6, locking key 7, second speed-limiting chuck 8, buffer spring 9, lead-out wheel 10; the inner left side of the slow-down lifesaving device 1 is provided with a rope winding drive wheel 2, and the rope winding drive wheel The rope on the 2 is wound on the speed-limiting slow-falling wheel 4 through the guide wheel 3, and the speed-limiting slow-falling wheel 4 is arranged on the right side of the rope winding drive wheel 2; the left side of the speed-limiting slow-falling wheel 4 is provided with a A speed-limiting chuck 5, the left side of the first speed-limiting chuck 5 is connected with a speed detection wheel 6, the speed detection wheel 6 meshes with the rope winding drive wheel 2, and the speed detection wheel 6 is connected with the locking key 7, and the lock The dead card key 7 is arranged on the lower end of the speed-limiting slow-falling wheel 4; the second speed-limiting chuck 8 is arranged on the right side of the speed-limiting slow-falling wheel 4, and the inner side of the second speed-limiting chuck 8 is provided with a buffer spring 9; The right side of the slow-down life-saving device 1 is provided with a pull-out wheel 10 .

The ropes wound on the speed-limiting slow descent wheel 4 are distributed in a cross structure.

The first speed-limiting chuck 5 and the second speed-limiting chuck 8 are herringbone structures, and rubber rollers are provided at both ends to mesh with the speed-limiting slow-down wheel 4 .

The working principle of this specific embodiment is: in the normal use state of the rope, the rope winding driving wheel 2 retracts and unwinds the rope at a constant speed under the cooperation of the driving power, and at the same time passes through the first speed-limiting chuck 5 and the second speed-limiting chuck 8. Cooperating with each other, the descending speed of the rope is strictly controlled; when the rope winding driving wheel 2 fails and stalls during the lifting process, the speed detection wheel 6 detects the rapid rotation of the rope winding driving wheel 2, and at the same time sends a signal to the locking card Key 7 tightly locks the speed-limiting slow descent wheel 4 to avoid accidents caused by too fast descent speed.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art can modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the utility model, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the utility model.
