Channel-type superhigh-lift fire fighting truck
At the beginning of calendar year 2001, the state-owned assets of hundreds of thousands dollar have not only been burnt in a big fire on the Moscow, Russia city colour TV tower, have lost a fire helicopter, also make the fire fighter of four braveries and eight, nine not guilty masses' life die a tragic death.This lesson written in blood must make us wake up suddenly, perfect day by day along with the continuous progress of human civilization and modern means of science and technology, no matter be that western developed country might as well or be similar to our the such developing country of China, numerous significant superhigh-lift buildings are more and more in the city.This Empire State Building.That federal iron tower, skyscraper miscellaneous is in a compact mass, and the highland stands between each city, well-known city, spreads all over five continents, the world.The most conservatively add up according to us: all kinds of building heights of having built up by the end of the whole world at the end of last century surpass 400 meters artificial structure thirties approximately; And the resemble construction thing that highly surpasses more than 300 meters also has 180; The high buildings and large mansions quantity that building height surpasses more than 200 meters is to surpass thousand, and the artificial structure of height can't add up already more than hundred meters.Just not saying other we temporary, single with regard to this work of structural fire protection, we make bold and draw a rash conclusion: the existing managerial skills of human civilization are far to lag behind its building ability one to have cut greatly.This is because as long as there is the people who is careful all to know up to the present slightly, the fertile five-star motor ladder that is exclusively used in fire-fighting of institute of country of modernized level in the world, and it highly only is 60 to 70 meter elevation that maximum is put out a fire.For those culture's fire more than hundred meters and hundred meters, can only be too far behind to catch up.And when in a single day above-mentioned building fire condition occurs, in the time of have to relying on this building initial designs supporting self fire-fighting fire-extinguishing equipment save oneself and attachedly help modern fire helicopter to cooperate.Yet how many factss of life are being warned us again animatedly: the helicopter fire extinguishing there is no too big effect for the artificial structure.This be because culture's structures shape its burning things which may cause a fire disaster that catches fire not be as forest fire with the institute combustion parts, the directly obvious floating there that rests leaves that you go watering, the spray foam.Its special character is that most reality are on fire for a part (or certain floor) in the middle of the building, above upright multilayer room and roof, you directly water of no avail at all across concrete, there arose a mighty wind and the fire went rolling and blazing often again for the characteristics of this while fire burns, wind helps upwards burning of firepower, forms the dense smoke roaring flame and shrouds whole roof.When the huge rotor of helicopter to it near again pyrotechnics being flashed, make us basic and can't see the scene clearly, hot and cold air crosses in the air, form the heat wave swing make helicopter at all can't near target (this wherein exists awkward: the one, bump near fearness wing and building; The 2nd, apart from water funk again rifle spray too far away less than fire point and can't implement rescue) add the extremely limited weight bearing power of helicopter, (manned just can't load bearing equipment and water) just be difficult to the normal effect giving full play to hydraulic giant and put out a fire big gun at all.Because careless slightlyly will lead to the same accident of Moscow colour TV tower, come to the fatal crass fire that also can not go out.And the fire fighting device of interior of building self tends to bring into play much effects because of the outage of catching fire, (it really acts on and only limiting to the initial stage of catching fire, in case the fire that has blazed up on a large scale that probably be self facility the condition of a fire that can't knock out.) can this be what if? just really be at a complete loss as to what to do? therefore humanly just can not build superhigh-lift again and build? no! This problem we the answer is in the negative.The clever mankind have that way solves.I have just designed a channel-type superhigh-lift fire fighting truck recently, and it just can greatly satisfy the needs of all modern superhigh-lift structural fire protection fire-fighting works fully, also for from now on more the fire house of elevation building need get ready.Can perhaps the someone say that you are boasting? do " superhigh-lift " hanged very much? no! Really believe me! So at first allowing me that what is explained is " superhigh-lift ".Saying its superhigh-lift, is not that it can want many higher positions how highly to come.Height is lifted in my its real fire extinguishing of designed superhigh-lift fire fighting truck will depend on the comprehensive bearing capacity in car load chassis.Be exactly its high ability of act of carrying tonnage decision of fire fighting truck frankly speaking.The tonnage of its car is big more lift high highly more.Below I am illustrated with a example the most plain: hang with 25 tons of wheeled cars such as me and carry the special-purpose assorted passageway for fire apparatus of 100 joints, it can be lifted and highly be about about 200 meters, and this is because our height of the designed special-purpose assorted every joint in passageway for fire apparatus is about two meters; 40 tons wheeled car hangs the maximum special-purpose assorted passageway for fire apparatus of 160 joints of then can carrying.Therefore about can realizing that promptly fire extinguishing is lifted up to 320 meters ... by that analogy, also can increase tonnage and climb the higher of act.Therefore, just be called " superhigh-lift ", meaning can surpass height of present all building elevations.And, along with the continuous progress of auto manufacturing technology in the world, the improving constantly of scientific and technological level, those large-tonnage bogies resemble our such developing country and also can make, make we be expected fully real reach eternal superhigh-lift want to.Certainly, this also needs us with rigorous scientism, carry out many-side comprehensively meticulously and adjust, and with the most perfect structure, the best equipment and go-go management means matches, and really accomplish safe and practical, with better function.Below I just in detail introduce the basic principle and the structure of this car particularly: it is to form through transformation with existing general wheel type hydraulic autocrane that the front had been mentioned my designed superhigh-lift fire fighting truck.Here need explanation a bit, we need select deadweight tonnage to be used as the transformation basis car of our new-type fire fighting truck on the truck crane chassis more than 20 tons generally speaking, and 20 tons too little with the bearing capacity of getting off, the act that is had height is limited in one's ability, and we do not adopt.At first we need become six bar hydraulic lifting base systems according to our design improvement with the main hydraulic means of the list of former car or two bars, are fixed on the chassis of main car.Again our the special-purpose passageway for fire apparatus one of self design is connect jacking successively, and progressively increase and stack certain altitude, why we to adopt this kind structure be to have used that modern bionic principle-----it is just as the pipe nipple mao bamboon, a section compact conformation is tight, have fabulous bending resistance, anti-wind-force is strong.And we adopt at the position that interconnects in the special-purpose passageway for fire apparatus of every joint is the structure of modern fire hose coupling assembling, to twist the button combination, accomplishes that Yi Lianyi simple to operate unloads and very firm wear-resistant.Certainly, our design is actually than the how several-fold bind mode of fire hose bracelet knot pawl, so its security is cocksure.In fact as for our designed special-purpose passageway for fire apparatus main body is exactly a kind of tubbiness hollow steel, constructed of aluminium, the light-weight metal body.The height of its every joint profile, thick than being 2/1.5 meter, strictness limits its every joint of conducting oneself with dignity must not be above 250 kilograms.Its effect is to increase successively to stack by one to reach us and operate needed height, then our fire-fighting soldier and equipment thereof is directly sent to the building edge that catches fire, and strides across to connect trestle and enter the scene of a fire and implement fire extinguishing and rescue again.Simultaneously we are also according to each different phase of fire-fighting fire extinguishing reality of work for this, and various differences required supporting designs and manufactures multiple special-purpose passageway for fire apparatus with specific use.For example: be equipped with automatic door structure and special-purpose passageway for fire apparatus classes such as escape hatch; Feedwater replenishes pressurization, and (mounted inside has one of electric pump, by with the car generator powered or directly communicate, guarantee the operating pressure of superhigh-lift fire water with ground power supply) pressurize special-purpose passageway for fire apparatus and external mounting of fire water special-purpose passageway for fire apparatus of backguy link etc. is arranged.All be equipped with in all these all kinds of special-purpose passageways for fire apparatus internal structures at us to can be used for artificial cat ladder emergent and maintenance, communicate successively up to the highest top layer; Inside, the special-purpose passageway for fire apparatus of every joint is also all installed to have and is gone up the logical single-phase cable of high-pressure metal water pipe, power that connects down, communication cable, program circuit, cctv surveillance circuit etc.; Their combination has constituted the channel system up and down (so be called the passageway for fire apparatus, it is again the origin of our channel-type) of a complete dandy lift again.And so numerous and diverse textural association fully all lifts a special-purpose ball-type fire extinguishing warehouse service to the high-altitude in order to realize from the master's car of ground; For Use Only in Case of Fire that the warehouse is multi-functional warehouse for this ball-type.It directly is located in the top, special-purpose passageway for fire apparatus that stacks.Inside, warehouse is equipped with a complete set of fire-fighting fire extinguishing specific purpose tool, resembles axe, hook, pincers, insulating bar, and gas defence, face mask for preventing smoke, oxygen cylinder, first-aid dressing etc. are exclusively used in the emergent at any time uses of equipment special such as processing is inflammable and explosive, sealing leak stopping in addition.This ball-type fire extinguishing warehouse still is the top exit of the dandy car mentioned of front, connects the part of the direct channel in ground and the high-rise scene of a fire especially, also is to realize lifting the forefront of sending the fire-fighting soldier to put out a fire and sue and labour.Be provided with the pullable suspension bridge door of an invert type in our side in ball-type fire extinguishing warehouse, towards outer unlatching.Just open internally as window, the balcony that can arbitrarily be overlapped in as the trestle with its building (perhaps can be farther) in five, six meters scopes far away once the staff, land the door and eaves, the edge of moulding etc., our fire-fighting soldier can arbitrarily enter the scene of a fire by it or to the floor that will go, directly comprehensively put out a fire and sue and labour then.In case of necessity, evacuate personnel and goods and materials etc. downwards by the miniature high-speed winch truck in our designated lane again.This ball-type fire extinguishing outside, warehouse also is equiped with equipments such as fire-fighting fire extinguishing work required illumination major light at night, high pitch loudspeaker, closed-circuit TV camera.Four sides, this fire extinguishing warehouse is towards being equipped with imitative cabin-type waterproof observation window, adds the telephone of internal configurations and carry-on wireless interspeaker, closed-circuit control TV etc. and constituted a complete set of fire-fighting fire extinguishing commander network thus.The close fit of our ground, high-altitude firefighters of leaving goes to finish the mission of oneself.And the miniature high-speed winch truck of our special-purpose passageway for fire apparatus mounted inside is exactly to connect tie up and down.It can remove to carry our fire-fighting fire extinguishing personnel and required equipment from the bottom to top, can also return ground from top to bottom and evacuate those personnel that saved out and valuable cargos.Only in this way we are just real has accomplished to sue and labour while put out a fire and has worked along both lines, and loss is dropped to MIN fire extinguishing commander rescue principle.And these any exactly existing aerial ladder cars all can't do and obtain.We so perfectly design want to also can be at last the peerless preferred plan of institute in the world at present.Certainly, we can create more perfect equipment, and the cost that our firefighters is paid on the scene of a fire is lower, and the property loss of retrieving for the people is also bigger simultaneously.Mention and perhaps someone will here and will ask: how is its security of so good equipment? yes, this important problems really.We have also moved many brains for this reason.For example: how to prevent toppling over of it; Which kind of scheme is a best wind resistance scheme etc.In fact the problems referred to above we already the design at the beginning of just given to take all factors into consideration.The warehouse of why putting out a fire is designed to ball-type, and special-purpose passageway for fire apparatus is designed to tubbiness and all is based on above-mentioned reason and does, and it is moderate to accomplish that really the windage minimum embodies weight again.We are the design freight weight limit in the special-purpose passageway for fire apparatus of strict regulations, ball-type fire extinguishing warehouse not only, also wants the bearing capacity (the highest staffing three people) of strict control dandy car simultaneously.Alleviate the weight on top with this, reduce the risk of " major part is heavy " as much as possible.Original four pin hydraulic pressure gravity support puts into the melting pot to ground master's car, strengthens stability energetically.More the more important is that we have used the four sides cable wire to draw solid technology audaciously, for this reason we also specialized designs four wireropes dispensing cars.As you know in our daily life, no matter who wants to guarantee that " the high stake thing " that erect not fall, even like flagpole, and the thing of antenna one class, simple effective method is exactly four jiaos of backguys.The blast that it can be resisted from any one aspect blows, and is not afraid of inclination even.Our wirerope dispensing car just is based on this principle setting and work.Its essential structure is exactly to drive the power source of a motor as driving and wirerope folding and unfolding with dc battery jar.And car load is equipped with locking device, brake gear, turns and fixture in the angle, room, and cable wire connects suspension member (the visible Fig. 9 of this loose mail structure) and openable ring-type fixator.Its operation sequence is: after our channel-type superhigh-lift fire fighting truck arrives assigned address, in the process of carrying out stable car, just come according to the burning things which may cause a fire disaster azel by we four veteran fire-fighting soldiers, staying cable wire hook in advance drives four electronic wireropes dispensing cars respectively and removes to seek separately fixed target (Xiang Dashu, electric pole, pier, angle, room etc. locate all can, preferably do not stride the road operation) towards four different directions.Lock vehicle after finding corresponding target, continue again slowly to discharge cable wire according to the actual conditions that main roof rises, (that can't see scene or jacking target can get in touch with operation by wireless interspeaker, and reality is not all right more also can operate according to the elasticity of cable wire) just can adjust the elasticity locking wirerope applicator of cable wire to desired height until jacking.Here must emphasize a bit, we must strict regulations when four road drag-lines still before the non-locking, forbid having in the fire extinguishing warehouse that jacking gets up people's operation of taking a risk, because in case to cause the car load problem of toppling will be very serious.We just can implement the superhigh-lift fire extinguishing relievedly to have only whole backs in place, give full play to the superiority of our new-type equipment, really accomplish safe and efficiently, help motherland and also help public.Believe: as long as our firefighters is through one section function of use and main points of systematically being familiar with and grasping these new-type each parts of fire fighting truck comprehensively, and the performance of our all facility of in real work, really accomplishing to bring into play to greatest extent, even if the fire evil spirit of height more than hundreds of rice, we also can wipe up it like a dream completely.
Required according to our vehicle operational performance of designed channel-type superhigh-lift fire fighting truck, every chassis should be equipped with nine of operating personnels (comprising one of driver, three of fire extinguishing persons, four of personnel of wirerope dispensing, one of terrestrial operation person; Appearance structure about wirerope dispensing car is finally decided by remaining space in the main compartment).
Below I form in conjunction with the structure that drawing is specified the each several part main part one by one again: Fig. 1 is the spot effect overall construction drawing of this invention.It has shown position, the scene of a fire and operation principle thereof under the channel-type superhigh-lift fire fighting truck simulated field state comprehensively.In the drawings, we as can be seen channel-type superhigh-lift fire fighting truck mainly be by 1, main car part (see Fig. 3 for details and amplify sample); 2, be seated main car and become the jacking pedestal (see Fig. 6 for details and amplify sample) of one with main car; 3, one be connected the special-purpose passageway for fire apparatus (see Fig. 7 for details and amplify sample) that stacks successively; 4, ball-type fire extinguishing warehouse (seeing Fig. 4, Fig. 5 expanded view for details); 5, be divided into four of four orientation--eight road steel drag-lines; 6, by opening and extend to the invert type trestle (see for details and launch pattern among Fig. 4) of floor window of catching fire in the ball-type fire extinguishing warehouse: 7, lifting capacity is that one ton truck-mounted crane parts such as (see Fig. 3 for details and amplify sample) is formed.In addition, because the relation of structure still has a dandy lift 8, is hidden in the fire extinguishing warehouse, it can be seen in the amplification sample by Fig. 4, Fig. 5, and the high and low of all personnel and equipment fully finishes by it.Among the figure we as can be seen its operation principle be essentially: by ground master's car 1, on jacking pedestal 2, successively with special-purpose passageway for fire apparatus 3, progressively jacking stack and lift special-purpose fire extinguishing warehouse 4.Arrive scene of a fire height and open door and expansion by stealthy fire-fighting soldier in the fire extinguishing warehouse, become connect trestle 6,, so just constitute a whole set of by the ring-like system of ground, under our the soldier's upstairs house of leaving, Lou Lilou implements in full fire extinguishing and rescue outward to the scene of a fire.In order to ensure trouble free service outside four road cable wires 4, (or eight road cable wires, eight orientation) four orientation, passageway for fire apparatus that will be towering is held firmly, even the God sweeps ten grades of strong wind " oneself steadfastly stands on one's ground for I ".
The practical work process of this invention channel-type superhigh-lift fire fighting truck is such: when channel-type superhigh-lift fire-fighting car owner car 1, carry ball-type fire extinguishing warehouse 4, come the extra-high-speed floor that catches fire before, at first steady good car.This simultaneously by one ton of arm 7 providing for oneself with car, with ball-type put out a fire warehouse 4, hang be sitting in jacking pedestal 2, on, and when its to the arm steel-hanging rope time four road pull lines also bolt is good.Then, with one ton of arm 7, continue with other vehicles drive come one successively special-purpose passageway for fire apparatus 3, hang in jacking pedestal 2, on, by pedestal 2, designated lane 3, is attached to together and jacking successively, picking-up hang with four road cable wires 5, the fire extinguishing warehouse slowly rise, simultaneously cable wire is also slowly emitted.Because the water of special-purpose passageway for fire apparatus 3, inner all outfits, to be electrically connected all be (see Fig. 8 for details, water pipe amplifies sample, be electrically connected to omit) of finishing automatically, thus operating personnel whether only need just can to grasp the part connection of getting up of jacking by signal feedback intact.Coming to this one is stacked successively until being raised to needed height, tells by telephone after the terrestrial operation personnel stop the instruction of jacking stay guy receiving fire extinguishing warehouse 4, interior soldier, opens the total water bolt in ground.The soldier who the is responsible for stay guy at this moment correct position of driving already to find, the locking cable wire of issuing an order, the fire extinguishing warehouse that height is high is locked motionless on four sides.And the soldiers in the fire extinguishing warehouse learn cable wire locking, open fire extinguishing warehouse arch form door at once, selected window (or balcony etc.) shake stretch many folding doors take in window advance you form between fire extinguishing warehouse and the window be connected trestle 6.So share out the work and help one another, the fire extinguishing personnel rush at the burning things which may cause a fire disaster spray cooling at once; The rescue personnel begins to seek the survivor.Find he (she) or the goods and materials that must evacuate etc. send ground back to by our dandy car again, until thoroughly finishing whole fire extinguishings and the task of suing and labouring.Because modern aerial ladder car is lifted high limited in one's ability, manufacturing cost is extremely expensive again.Believe: our channel-type superhigh-lift fire fighting truck is bound to give play to immeasurable effect in the modernization construction of in world wide from now on each big small country.
