Description
Technical field
The present invention relates to the quality expansion training field of fire-fighting and rescue, mountain-rescue, show business, a kind of base
Rapidly descending escape and rescue cableway device in all kinds of ropes.
Background technology
Along with the development of urban economy, the quantity of high building grows with each passing day, and fire incident and hidden danger increase the most day by day.At fire
In accident, the immediate cause having the considerable part personnel casualties is blindly to jump out of the building, and China's fire-fighting emergent rescue outfit ability is with high-rise
The fast-developing serious unbalance of building.The current limitation in height of fire-fighting emergent rescue outfit, mobility are poor, are affected by surrounding enviroment
Seriously, have become as and affect the critical defect of the effective fighting and rescue operations of high building.
One, the defect of existing deliverance apparatus
1, existing descending lifeline has several feature: one is that rope is integrated with descending lifeline, it is impossible to separate so that once can only
Escape a people；Two is that the top to rope is fixed with particular/special requirement；Three be operation complexity, do not have trained not
Understand how to use；Four is vertically to decline.These common ground can not solve in emergency circumstances, many people fast-escape special
Situation, and seal building in big fire, dense smoke and raging fire are outwards emerged from window, and metope environment is (such as air-conditioning, anti-theft net, clothes horse
Deng) in the case of complexity, it is impossible to vertically decline.
2, a lot of products such as fire tanker, fire control aerial ladder vehicle etc., bulky, cost is high, mobility is poor.They operations
Also needing to supporting leg and balance, heave amplitude is big before, and rising or falling speed is slow, and its motility, stability have certain restriction, it is impossible to
Meet the needs of escape and rescue.For higher fire of high-rise building, can only be " watchtower is heaved a sigh ".
While the quantity of skyscraper rapidly increases, and story height is also constantly refreshing.Along with these high levels are built
The service life built increases, because the reasons such as electrical equipment is aging cause the hidden danger of fire also increasing.Super High inhabitation amount is big, flow of the people
Also big, once there is sudden disaster, consequence is hardly imaginable, rescues the operation irregularity difficulty of a large amount of crowds in the short time.
Faced with this situation, traditional truck is the most not competent.The height of fire fighting truck is the highest, from heavy sensation of the body
Measuring the biggest, volume is the biggest, and payload during high workload is the least, and emergency management and rescue action is the most inconvenient.Therefore,
Helicopter because of its have mobility strong, be swift in motion, not by characteristics such as story height are limited, and be increasingly becoming fire-fighting and rescue and have most
The weapon of effect.
Two, the defect that the principle of fire-fighting and rescue and existing helicopter are directly rescued
Sum up a set of rescue principles according to Wenchuan earthquake rescue work, be also adapted to fire-fighting and rescue field:
(1) the security doctrine of rescuer self
Save the precondition that rescue strength is to ensure that subsequent rescue work is carried out steadily from damage.When disaster happens suddenly, various rescue
Help resource to seem epitonos, preserve existing rescue strength and seem and be even more important.
(2) the ageing principle rescued
Other disasters such as fire in high buildings and earthquake are different, once breaking out of fire, process not in time, will be fast to more high-storey
Speed is stretched, and temperature is more and more higher, and poison gas is increasing, is all caused increasing psychology panic to rescuing, it is therefore necessary to
Within the shortest time, shift and substantial amounts of rescued personnel.
(3) put into minimum, the principle that results are maximum
It is known that find fire the most early, the resource putting into fire-fighting is the most, and fire is the most easy to control, loses the least.Helicopter
As the scarce resource of tall-building fire fighting rescue, the key link of fire-fighting should be used it for as far as possible, reduce unnecessary taking, carry
High utilization ratio.Fire fighter, as effective strength most important in fire-fighting, also should put in the control of the intensity of a fire as far as possible
Go, reduce unnecessary taking.In a word, the biggest return should be obtained with few input as far as possible.
