Description
Technical field
The invention belongs to human body air security preventer field, more particularly, to a kind of damp slow falling device.
Background technology
When fire-fighting and other field carry out rock-climbing training, climb object and be mainly rock cliff or artificial dike.Climb
When trainer only armrest foot and body balance move upwards, handss and arm will according to the difference of fulcrum, using various firmly
Method, such as grabs, holds, hangs, scratches, supports, pushes away, presses, so the flexibility requirements of force requirements to people and body are all higher.For true
Protect personal security, existing training mode, generally require rock-climber and fasten one's safety belt and protect rope, be equipped with rope etc. and to avoid danger
Danger.But, it is very inconvenient that above-mentioned protective measure uses, and training effectiveness is subject to severely restricts.
In addition, rescuing field, the fast development of current China emergency management and rescue equipment capability and skyscraper in fire-fighting emergent
There is serious unbalance situation, one is the high development elevating ability far behind skyscraper of equipment, existing highest cloud
Tower wagon elevates also only 15 layers about of ability, and for higher fire of high-rise building, these emergency management and rescue equipment can only be
" watchtower is heaved a sigh "；Two be equipment bulky, mobility poor, affected seriously by road traffic, building surrounding enviroment, frequent because
Complicated landform, obstacle stop and miss an opportunity because of a delay, and three is that the rescue ability equipped is poor, and existing motor ladder once lifts can only be succoured
2 to 3 people, once meet fire in high buildings it is impossible to meet the actual rescue in scene needs.
With the continuous quickening of China's industrialization, urbanization process, above-mentioned contradiction also will become increasingly conspicuous, and data with existing shows
Show, the presented situation that accelerates of some flourishing urban skyscraper fire incidents of China.
How emergency escape during high-rise building with fire disaster, has become as the social problem of people's highest attention.In order to change
