Description

A kind of near-earth buffer unit of life line

Technical field

The present invention relates to the near-earth buffer unit in lifesaving appliance field, more particularly to a kind of life line.

Background technology

In disaster field, the disaster victims and people trapped in danger if necessary to rescue apart from home farther out, rescue personnel can typically use Life line and combination of pulley are used as simple rescue tool.Especially in scene of fire, for also in the stranded of architecture storey on fire The masses, life line and coaster are even more to be used as important escape device.The coaster of rescue is generally used for, is equipped with close to ground When can the intelligent apparatus that stops of automatic brake, prevent coaster " breaking through head ".Common intelligence stop device of stopping has sensor and stop signal Mark combination, also there is the device that brake is detected using near-earth.But, above-mentioned or other intelligence commonly used on the market are stopped stop device All it is the device of electronization, as long as the device of electronization, there is the possibility of failure, the mechanism for stopping coaster for stopping may also Occurs the abnormal situation of other extreme mechanicals.Although there is failure is an extremely low probability event, this is effectively related to and multiplied The personal security of coaster is sat, discounting for this situation and counter-measure is set, once failure occurs, consequence will can't bear to set Think.

Therefore, prior art has much room for improvement and developed.

Fig. 2 is the use structure chart of the near-earth buffer unit of life line.

Embodiment

To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings The present invention is further described.

Referring to Fig. 1-2, the invention discloses a kind of near-earth buffer unit of life line, the device is arranged on life line 7 Lowermost end, it is abnormal in the near-earth of coaster 8 stop device other extreme mechanicals that break down or occur of stopping as back-up safety mechanism In the case of, cushioning effect is played, coaster 8 is unlikely to directly punching ground, makes passengers inside the car injured.Referring to Fig. 1, life line Near-earth buffer unit 6 mainly includes buffer body 1 and binding structure 4.Wherein, the center of buffer body 1 is provided through lacing hole 2, and A rope inlet 3 is extended outward from lacing hole 2, rope inlet 3 is exactly the breach formed on buffer body 1 in fact.Specifically , as long as it ensure that human body strikes against the manufacture material that buffer body 1 is can act as all without the material come to harm suddenly Material.At least two, structure 4 is bound, and is respectively arranged at the both sides of rope inlet 3.Further, if binding structure 4 only has two It is individual, i.e., only a pair, then the middle part of buffer body 1 is preferentially arranged on, plays the binding effect of maximum；If binding structure 4 has many It is right, then the positions such as top, waist and the bottom of buffer body 1 can be separately positioned on, binding function is further enhanced.Specifically, Binding structure 4 can be any device for being easy to quickly bind and take apart.When actual use, life line 7 is set to enter at rope inlet 3 Enter to lacing hole 2, then fixed using the binding structure 4 on the both sides of rope inlet 3, the breach of rope inlet 3 is closed, makes life line 7 It can not deviate from rope inlet 3.Referring to Fig. 2, near-earth buffer unit 6 is arranged on the lowermost end of life line 7, near-earth buffer unit 6 It is a pure physical protector, as long as carrying out the maintaining to near-earth buffer unit 6 in advance, and sets at the scene It is good, avoid the need for worrying that as electronic equipment unpredictable failure can occur for near-earth buffer unit 6.Near-earth buffer unit 6 as a final security mechanism, it is necessary to when can with rapid deployment, can simply and effectively protect take coaster 8 personnel peace Entirely.

Specifically, as long as ensure that human body strikes against suddenly can act as buffering all without the material come to harm The manufacture material of body 1.In order to reduce manufacturing cost, buffer body 1 can select to use foam-rubber cushion.Soft foam-rubber cushion is buffering dress Conventional material is put, its practicality is obvious to all.In addition, storing for convenience, buffer body 1 can also be air bag, specifically , can be central column air bag.Air bag is also a kind of conventional padded coaming, and the setting of inflatable is more convenient not Deflate and store when needing to use, space can be greatlyd save, and transport also very convenient.In actual use, if wide short The air bag of type central column, can be superimposed with two or more air bags and used, as shown in Figure 2.If wide high The air bag of type central column, then can only use single air bag.Meanwhile, in order to prevent single air bag by super Explosion when crossing the moment impact of its specified stress, accidentally injures the masses around air bag, can be in advance on air bag surface The individual safe breach 5 of Position Design one for being not easy to damage surrounding people.The size of safe breach 5 is with filling The volume size and materials of gas air bag are relevant, need safe breach 5 to accomplish in principle：When air bag by more than During the moment impact of its specified stress, safe breach 5 is the place ruptured at first, and safe breach 5 can be with certain gas Flow discharges air bag inner air, and this certain throughput will ensure that other positions of air bag will not be because of pressure Excessive and explosion.For example, it is assumed that air bag volume is close with Boxing sand bag, the size of that safe breach is with general Logical disposable paper rim of a cup on the market（About 8 centimetres of diameter）It is close.Assuming that air bag uses high tenacity, air-locked cloth It is made, then the cloth at safe breach 5 can be made thinner than the cloth at other positions of air bag, can so ensure inflating air Capsule is ruptured first by safe breach 5 during moment impact more than its specified stress, and the safe particular location of breach 5 can be set Put in air bag bottom, can so reduce the influence to surrounding people.

Specifically, binding structure 4 can be any device for being easy to quickly bind and take apart.It is live amateur for convenience Personnel also can rapid deployment and installation, binding structure 4 can be high-ductility nylon rope.High-ductility nylon rope is with low cost, tightens With disassemble all easily, and ruck can operate.

In summary, the invention discloses a kind of near-earth buffer unit of life line, it is necessary to when can be existed with rapid deployment The bottom of life line, breaks down or in the case of occurring other extreme mechanical exceptions in the near-earth of coaster stop device of stopping, plays Cushioning effect, makes coaster be unlikely to directly punching ground.Near-earth buffer unit apparatus structure is simple, and easy for installation, manufacturing cost is cheap, It is pure physical protector, and may be reused without destroyed near-earth buffer unit, solves well when electricity Sonization near-earth stop stop device break down when coaster directly rush ground, easily cause take coaster injury to personnel the problem of.

It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention Protect scope.
