Abstract

The utility model relates to a tall-building fire escape apparatus, which comprises a casing body. An escape device is arranged inside the casing body; a rope fastener is arranged on the casing body; the escape device includes a centrifugal friction device, a gear combination device and a rope gear connected with the gear combination device; and the gear combination device is connected with the centrifugal friction device. Steel wire ropes are slowly controllably released, and energy (the body weight of escapees) on a steel wire rope reel is transferred to a tail end reel step by step through multi-step transmission. As a centrifugal block and a friction plate are installed on the tail end reel, the higher rotation speed corresponds to the larger centrifugal force corresponding to the larger friction force produced by the tail end reel, thereby the escape apparatus can retard rope releasing speed of the steel wire rope reel so as to achieve the purpose of slowly controllably releasing the steel wire ropes. The escape apparatus has the advantages of reasonable design, simple structure, low manufacturing cost, usability without special installation, convenience for being popularized and capability of being used without training.

Description

The escaping from high building on fire device

Technical field

The utility model relates to a kind of survival equipment, especially a kind of escaping from high building on fire device.

Background technology

In recent years, along with the continuous quickening of China's industrialization, urbanization process, the construction of skyscraper is also maked rapid progress, and the development speed of China's skyscraper is highly visible.The appearance of these high-rises has reflected China since reform and opening-up, the raising of national economic strength and Level of Urban Modernization.Yet, say that from security standpoint skyscraper has proposed two new problems for science and technology again: how to prevent fire and earthquake.In case skyscraper breaking out of fire, its consequence are very serious, many traditional means of fire and disaster relief measure are at this moment usually inapplicable.General merchandise building, the Jilin fire that shocks the world, Harbin swan restaurant fire, Foochow century Xinhua fire all ... all these have beaten alarm bell for us again.Just in case breaking out of fire, how does trapped personnel escape?

A lot of fire of high-rise building have taken place in all parts of the country in recent years, and a large amount of property losses, casualties have caused the extensive concern of the whole society.Because it is big that skyscraper has a space, the inhabitation personnel are many, story height, evacuate the characteristics of difficulty, in case breaking out of fire is difficult to put out a fire to save life and property, are difficult to escape, are easy to cause the safety problem of the major accident high building that the dead group of group the hinders hot issue that becomes international.Since the reform and opening-up, China's big and medium-sized cities middle-high building also rises sheer from level ground two like the mushrooms after rain, lives or the number that is operated in the high buildings and large mansions grows with each passing day, and the fire-proof lifesaving of skyscraper has also become the important topic of China's urban safety.The development of fire-fighting emergent rescue outfit ability and skyscraper is seriously unbalance at present, the one, the high development that the act height of equipment and long shot lag far behind skyscraper, existing fire tanker sprinkling fire ability only is 8 floor height, the highest motor ladder is lifted high ability and is also had only about 15 layers, for higher fire of high-rise building, these emergency management and rescue escape equipments can only be heaved a sigh by watchtower; The 2nd, the equipment bulky, mobility is poor, influenced seriously by road traffic, building surrounding enviroment, often because of with a varied topography, that obstacle stops etc. is former thereby miss an opportunity because of a delay, the 3rd, the rescue ability of equipment is poor, an existing lifting of motor ladder can only be succoured 2 to 3 people, in case meet wildfire, can not satisfy on-the-spot actual rescue needs.Along with the continuous quickening of China's industrialization, urbanization process, above-mentioned contradiction also will become increasingly conspicuous, and data with existing shows that some flourishing urban skyscraper fire incidents of China have presented quickens rising situation.
