Description
The right that the application requires to enjoy in and filed an application on January 27th, 2003, application number is 60/442265 U.S. Provisional Application file.
Technical field
What embodiments of the invention related generally to is, when the emergency situation that occurs as fire and so on, fire fighter and equipment liter is reached the upper floor of tier building, and withdraws personnel from upper floor.Other embodiment has also been described.
Background technology
When being in an emergency on the skyscraper such as tier building or during disaster, order emergency personnel (as fire fighter and paramedic) alleviates disaster or rescue and is trapped in people in the building.September 11 calendar year 2001, World Trade Center's mansion in New York was exactly a very fearful example.Under the sort of situation and since on the low layer big fire to cause building the people on upper strata stranded.In addition, emergent stairwell has been full of flue dust and deletrious gas, or can not implement salvage work effectively fully owing to remains.Although the people is arranged being lower than on the fire floor, some are because injured and can not get off from emergent stairwell among them.In brief, need a large amount of evacuation crowds from all these upper floor exactly.Word herein " upper floor " is meant the above part of ground (as ground floor) of tier building.
Because most of upper floor are too high, use usual scaling ladder also to be not easy to enter from building external, the emergency personnel has to climb up hundreds of grades of ladders (the common SELF CL of elevator when the building presence of fire).Even more serious is, they have to bear high temperature and flue dust in the way of stair climbing, but also is bearing quite heavy weight equipment, as oxygen bottle, medicine box and be used to alleviate the condition of a disaster and help the necessary miscellaneous equipment of the wounded.Unfortunately, corrode the speed of building with respect to big fire, it is too slow that the process of stair climbing seems.Corrode the speed of building with respect to big fire, it is too slow that the process of stair climbing seems.Some emergency personnel even can have a heart attack or suck flue dust and cause injury after having climbed several grades of stair.Some evacuees particularly are arranged near the people of the top floor the roof, can be rescued by the emergent helicopter that drops on the roof.Yet, still have appreciiable people and have no option causing death, otherwise burnt alive or be choked to death by big fire except jumping out from the building window.
Several systems that are trapped in tier building upper floor people that are used to succour are disclosed now, referring to as U.S. Pat 4209077, US4919228, US4355699, US4424884, and US4406351.Some usage platforms or hanging basket in these systems, they lean against on the outside wall surface of building by cable is outstanding.Lifting or decline platform are to the other desired position of upper floor.People withdraw from from floor, and the platform that is mounted with the evacuee then drops to safe place (near the normally ground the building).Yet some problems may appear in these systems, comprise processing or service expenditure that cost is higher relatively, and the complicated operations process.

The specific embodiment
According to one embodiment of present invention, described the system and method that arrives from the outside of tier building upper floor, its cost benefit is more to one's profit.Native system comprises an osed top loop-forming cable, and this cable is twining pulley, and this pulley is positioned at a certain position on roof or the building upper floor.The length of loop-forming cable can arrive a certain zone (when it is allowed to be installed in the outside of building) near building lot at least.Loop-forming cable links to each other with winch, and this winch preferentially places the zone near building lot.In case loop-forming cable correctly links to each other with winch, and winch is installed to correct position, and preferentially, loop-forming cable compensates the part (with respect to building) of loop-forming cable far-end rope and near-end rope under the tension force effect with certain length.In when work, weight is acting on loop-forming cable near on the zone of building lot, drives winch then and promotes described weight and arrive up to weight, and be hung in predetermined height, and this height is approaching with the height of building upper floor.
The loop-forming cable that is stopped to drive by winch when weight is suspended in when aerial, by other technology, moving heavy object near or leave building, for example, winch is moved up or down with respect to building, make suspension heavy weight location near building, thus turnover from building easily.Also removable vehicle on even keel on building lot is near building, and this device is gone up anchoring the winch building.In addition, when vehicle kept static, winch can upwards be moved with respect to vehicle.Another method is also arranged, one or more movably pulleys that loop-forming cable twines are moved, when winch stops to drive and keeps static, in loop-forming cable, discharge certain slack, with regard to the close building of the weight of removable suspention.Another method is that the loop-forming cable close end office under weight changes tension force, be to reduce tension force mostly, thereby mobile suspension heavy weight is near building.
Weight comprises a casing, withdraws (when casing is suspended near the upper floor side) so that people enter in the casing from upper floor.In case after casing is loaded, oppositely drive winch, it just can leave building, preferentially make the evacuee drop to safe place (for example, the zone of close building lot).For example, with downwards or the direction of leaving building move winch, make the weight of suspention leave building.In addition, when vehicle kept static, winch can be moved downwards with respect to vehicle.Another method is also arranged, and also removable vehicle on even keel on building lot leaves building, and this device is gone up anchoring the winch building.One or more movably pulleys that loop-forming cable twines are moved, when winch stops to drive and keeps static, in loop-forming cable, strain slack, but just the weight of drawing suspention leaves building.Another method is that the loop-forming cable close end office under weight changes tension force, be to increase tension force mostly, thereby mobile suspension heavy weight leaves building.
The various accident equipment that one or more embodiment of the present invention described herein also can fast and effeciently promote such as fire appliance, air pipe and hose, heavy equipment and emergency source of electrical power arrive the upper floor of building.Like this, the fire fighter just needn't shoulder they the building stairwell in climb.This also helps to reduce in stairwell, and transportation is blocked and load, and provides more fire appliance to accident point in the identical time.
Native system not only can perform well in upwards transporting fire fighter and equipment, and withdraw the occupant, and can be used for the building (particularly those do not have the building of water sprinkling system) of low clearance from the high building floor of stretching distance that surpasses fire-fighting vehicle commander ladder.This is to have the ability to promote and descend bigger load because it is compared with existing trapezoidal system.In addition, it transports the evacuee than ladder is easier.Compare it hangs basket or hanging basket to transport the disabled person easier by box with ladder.
Some part of embodiment logically also can directly be revised.For example, a relatively low erected cost will be born by building resident family, mainly is the expense of the pulley pulley annex of building (and be installed to) and loop-forming cable.Winch is installed on the conventional vehicles or standard form truck of fire brigade.In addition, using native system to promote and deposit non-emergency serving unit also is favourable (built-in elevator device may be unactual in the use building) to arbitrary upper floor.Use native system to also have other advantage or benefit, will further describe hereinafter.
With reference to figure 1-3A, they show the lateral plan and the front elevation of system 20, and this system is the upper floor 507 in order to enter tier building 500.This building 500 has 502, one grounds 506 of a roof that have Stall corner 504, and big fire occurs 510 front or sidewall 508.Roof 502 herein can be the actual roof of building 500, also can be the rotine positioning near building 500 tops.Ground 506 can be on the ground, also near on ground-surface another horizontal surface, or is adjacent to the zone that emergency serving unit and emergency personnel can assemble, at the condition of a disaster accident point in the building (for example, the roof of another adjacent architectural-not shown).
In the present embodiment, pulley 22 is installed near on the roof 502 of corner, building 504.Also can select certain of the building on the upper floor that pulley is installed.Distance between pulley 22 and ground 506 is represented with height H in vertical direction.Pulley is installed be will be described below to architectural several different methods.
Native system has also been described a closed ring cable 28 that is wrapped on pulley 22 and the winch 24.Described cable can be a steel rope, rope, chain, cotton rope or analogue, and it has enough intensity to suspend in midair will to be connected the predetermined weight on the cable, as evacuee and emergency personnel and equipment.As shown building outside, loop-forming cable 28 long enoughs can arrive the zone that the emergency personnel that is positioned at the pulley below assembles, and this region adjacent is in the ground of building 506, at the condition of a disaster accident point in building.For example, among the embodiment shown in Figure 1, the total length of closed ring cable is about the twice of height H, promptly is, owing to there is distance D 1, its length is longer than the twice of height H slightly, as shown in Figure 1.In a preferred embodiment, loop-forming cable 28 twines graphic pulley once, and twine winch 24 just once just.In other words, there is not the multiple winding of loop-forming cable on pulley 22 and the winch 24.Yet also optional majority time winding cable is on pulley or winch.Therefore, in many cases, the total length of loop-forming cable 28 depends on the height of building 500, the loop-forming cable of the building fitness for purpose different length of differing heights.
In the present embodiment, system 20 shown in Figure 1 also comprises a casing 30 that is used to hold people and equipment, and it is connected in the proximal part 31 of loop-forming cable 28.This casing can be a platform that has a movable net, hang basket (illustrating), a cage, hanging basket, gondola, or is used to transport other structure that evacuee, emergency personnel or equipment debouch tier building 500 upper floor.If a plurality of casings use in native system simultaneously, they are preferably along relative position setting on the loop-forming cable 28 so, (for example be convenient to like this when casing 30 moves to roof 502, the assistance evacuee), another casing 32 that is connected distal portions 29 moves to ground 506 (for example, transporting the place of evacuee to safety) simultaneously.Such example is referring to Fig. 3 B.Native system also can select only to have the structure of a casing 30, and the cost of its configuration and operation is lower.
Two different examples when Fig. 1 and 2 has described the native system operation.In Fig. 1, winch 24 moves to the position of distance for D1 (sidewall 508 perpendicular to building is measured).Contrast, in Fig. 2, winch 24 moves (passing through powered vehicle 26 in the present embodiment) to larger distance D2 place (sidewall 508 perpendicular to building is measured).When winch 24 is positioned at the D1 place (shown in Figure 1), casing 30 relies on the sidewall 508 of building, and has certain slack (it is fixed between the position of loop-forming cable 28 at winch 24 and casing 30) at proximal part 28 places of loop-forming cable 28.Yet, notice that distal portions 29 places of loop-forming cable 28 do not have slack (because cause of casing 30 gravity) basically.
When outside mobile winch 24 during to distance D 2 places (shown in Figure 2), distance L increases and H remain unchanged (referring to Fig. 1).In addition, the slack at loop-forming cable 28 proximal parts 31 places reduces, with respect to sidewall 508 with enough big angle at architectural unhinderedly drawing casing 30.For example, when casing 30 descends, help protecting arbitrary evacuee and rescue worker in casing 30 not to be subjected to big fire 510 or other dangerous influence of building or giving prominence to objects from sidewall 508 like this.Winch 24 can be adjusted as required with respect to the position of building, the tension force at adjustable collar shape cable 28 proximal parts 31 places not only, and can by loop-forming cable near or leave any weight that building moves suspention.
Should be noted that, the length overall of design loop-forming cable 28 should be taken into account rational distance D 1 and D2, and it is dropped in the area division that is adjacent to building lot 506, preferentially, emergency serving unit and emergency personnel enter this zone easily, at the condition of a disaster accident point in the building 500.Yet, also can select parallel motion winch 24, adjust the tension force of loop-forming cable and the level attitude of weight and form its perpendicular movement (or resultant movement of two kinds of directions).For example, winch 24 can be installed in the short and small elevator type mechanism.Also winch 24 can be fixed on the ramp in addition, it be changed with respect to ground-surface slope angle by driving an actuating unit.Also can select to increase or reduce the tension force of loop-forming cable 28, can change the position of suspension heavy weight like this with respect to building sidewall 508 from the suspension heavy weight below to section between the winch.
In an embodiment, second casing 32 is connected in distal portions 29 places of loop-forming cable 28, and Fig. 3 B shows the lateral plan of native system 20 dual structure embodiment.Be connected heavy weight weight (if a plurality of weights are arranged) on the loop-forming cable and be close to the sidewall of building often most.Therefore, present embodiment as shown in the figure, the position of having only casing 30 (wherein being mounted with evacuee or other weight) is the sidewall of close building.
Translate into Fig. 4 A now, its show mobile suspension heavy weight (casing 30 connect loop-forming cables 318) herein, near or leave another technology of building 500 sidewalls.The system of present embodiment has 322, one winchs of a top pulley or hauling block 324, and four auxiliary pulleys 328,332,336 and 340 one group of pulley forming.Some of them or all pulley 328-340 preferentially are installed on the same vehicle, and winch 324 also is fixed on the described vehicle.Loop-forming cable 318 twines all pulleys.Notice that the disproportional sign of this figure only is used for describing the operation of native system.In fact, relevant size, position and the quantity of pulley 322-340 all are different from diagram.With reference to example, only there are two auxiliary pulleys 426,428 to be positioned at the both sides of winch 424 in the system in Fig. 4 B, the tension force of cable can increase at distal portions 29 places of loop-forming cable 418 or reduce, and proximal part 31 places of loop-forming cable also are like this.
With reference to figure 4A, mobile pulley 332,340 (are also referred to as and regulate pulley) are to the left side of figure, and other all pulley transfixions in the maintenance native system, increased the tension force at proximal part 31 places below of casing 30 (suspention) of loop-forming cable 318, and casing 30 (just suspending in midair) has been moved right leave building 500.On the contrary, mobile pulley 332,340 has reduced the tension force from proximal part 31 places to the right (and keep other all pulleys static), thereby casing 30 is moved to the left near building 500.More extensive, design any one or a plurality of pulley 328-340 and become movably, be convenient to the increase of tension force being scheduled at proximal part 31 places like this or reduce.Same explanation can apply among the embodiment of Fig. 2, and herein, moving vehicle 26 can increase the tension force that is positioned at suspension heavy weight below proximal part 31 place's loop-forming cables to farther distance D 2, so drawing casing 30 leaves building 500.Vice versa, and casing 30 is retracted near building.
Translate into Fig. 4 C now, its show mobile suspension heavy weight (casing 30 is connected to loop-forming cable 468 herein) near or leave building 500 sidewall.The system of present embodiment has a top layer pulley 462, the top that it can for good and all be installed to roof or build 500 upper floor, winch or hauling block 464, and one group of two auxiliary pulley 465 and 467, promptly so-called " guiding " pulley, one of them or two leading sheaves 465,467 preferably are fixed on the same vehicle (not shown) with hauling block 464.
In addition, native system also has removable or adjustable pulley 466, regulates pulley 466 in the present embodiment and is " drift ", because it is only fixed by loop-forming cable 468 and the tension force of regulating 474 of cables.In the present embodiment, regulate pulley 466 and drift about, and other all pulleys (pulley 462,464,465,467 and 472) of diagram native system are maintained fixed.The tension force of loop-forming cable 468, particularly the tension force at proximal part 31 places below suspention casing 30 can be regulated by cylinder winch 470.470 rotations of cylinder winch are selectable to regulating cable 474 drawings and relaxing.An end of regulating cable 474 is wound on the cylinder winch 470, and the other end is connected to be regulated on the pulley 466, and twines pulley 472.
When regulating pulley 466 drifts, pulley 472 preferably is permanently secured on the other building 500 of ground, as shown in the figure.On the other hand, hauling block 464 and leading sheave 465 and 467 are with cylinder winch 470, be fixed on the vehicle (as, fire extinguishing tanker), not shown, if the place of emergency situation is arranged in the building, described vehicle will arrive the area of accident in the other zone of ground of building 500.Same vehicle can be used to transport adjusting pulley 466 or pulley 472.The operator of native system (as the emergency personnel) can drive on the direction in the both forward and reverse directions of hauling block 464, lift and promote suspention casing 30, and can drive on the direction in the positive and reverse return veer of cylinder winch 470, move suspention casing 30 near building 500 sidewall with leaving.
As indicated above, top layer or upper sheave 22 can for good and all be connected on the supporting construction of building 500, and are positioned at the single position on 504 sides, corner of roof 502.Shown in Fig. 5 A, layout is changeable, makes to be suspended in the extended position of pulley 22 shown in can be on roof 502 moving to from punctured position on the corner 504 at extended position place pulley 22.The parallel axes of pulley 22 is fixed in the front or the sidewall of building shown in (or perpendicular to).Axis also can be selected to rotate, and just can form multiple angles with sidewall 508 when it moves in system like this.In addition, loop-forming cable 28 also can be deposited on the roof 502, as deposits in the housing 34.Loop-forming cable 28 can launch automatically at that time, at first twines pulley 22, falls then or loop-forming cable is fallen from roof, and it just can arrive winch 24 places like this.Loop-forming cable 28 also can be selected to be wound on the pulley 22, and leaves in the vertical housing 36, and this housing stretches out downwards along the front 508 of building 500.In this example, can be by opening vertical housing 36 expansion loop-forming cables 28, loop-forming cable dropped on the winch 24 that will twine.In the embodiment that launches automatically, a kind of mechanical device of automatic expansion loop-forming cable is provided, after it receives the electric wave signal of fire brigade or other mechanism, just move native system.In order to launch loop-forming cable 28 quickly, loop-forming cable can extend downwardly into ground fully, and always is fixed on the other zone of building lot versatilely before search operations launches.
With reference now to Fig. 5 B,, it shows casing 530 and leaves the distal portions 29 that a fixed gap is given loop-forming cable 28.Casing 530 has two weight zones 534,536, and they are connected on the shared pillar 535.One end of loop-forming cable 28 passes apical ring 531, and (for example by hook with safety tong) is connected on the bottom enhancing ring 533.On the bottom enhancing ring 533 shown in the other end of loop-forming cable can be connected to.The stabilizing mechanism of some forms (as, referring to Fig. 9-10) can increase the stability of casing 530, building casing 530 this moment is in building 500 other suspentions and be raised or descend.
Translate into Fig. 6 A now, it is the front elevation of native system 20 another embodiment.In the present embodiment, two tool pulleys 22 at regular intervals are installed on the roof 502.In this example, loop-forming cable 28 twines two pulleys 22 and winch 24.In the present embodiment, the axis of pulley 22 is not the front 508 (shown in Figure 14 C) that is basically parallel to building, but is substantially perpendicular to positive 508.This pattern is useful to the embodiment of sided configuration, because will keep the interval of broad between two casings, reduces the probability of two tanks 30,32 phase mutual interference when mid point moves.It also provides two mutual " loaded " position, and this position is close in the same side (contrast Fig. 3 B) of building abreast.
Compare with the embodiment of Fig. 6 A, Fig. 6 B and 6C show two side forms of native system, and wherein different " loaded " position is close in two different adjacent walls 508 and 509 of building.In the present embodiment, two pulleys 22 lay respectively near the top of the other building 500 in adjacent wall 508 and 509 corners.Fig. 6 B is a front elevation, and Fig. 6 C is a side perspective view.Notice that two the diverse location A and the B of winch 24 is provided, and they are positioned near the bottom or ground of building 500.Position A more approaches sidewall 508 and 509 (perhaps at a higher height) than position B.When winch 24 during, be connected respectively to the different edge 29A of loop-forming cable 29 and the suspension heavy weight (not shown) of 29B, more approaching building 500 at position A.Outwards or move down winch 24, the sidewall 508 and 509 that will mobile suspension heavy weight leaves building to position B.At last, drive winch in one direction and will promote a weight, another weight that descends simultaneously, and if winch reversing sense when driving, opposite situation will appear.
With reference now to Fig. 7 and 8,, it illustrates the method flow diagram that enters from the upper floor outside of tier building.Present described method, interim embodiment (this method also is applied to the embodiment of unshowned system 20) with reference to the system 20 shown in the figure 1-6C.The request of the building of entering at first will be arranged, and the ambulance call 911 when for example the condition of a disaster takes place could move at the built-in elevator of the condition of a disaster accident point building, and whether perhaps enter upper floor by the stairwell in the building reliable or too impracticable.After answering request, the transportation winch is to the other zone (104) of building lot.Launch loop-forming cable downwards to winch, loop-forming cable is wound into effectively and is installed in architectural pulley (108) herein.In some cases, can fully launch loop-forming cable, for example be fixed on the building lot, the operator of winch can enter this ground.Also in some cases, loop-forming cable is wound on the winch, does not have the osed top loop-forming cable if having, with regard to closed ring cable (112).In this, when loop-forming cable is installed on the winch, on loop-forming cable, preferably leave certain surplus, be easy to be installed on the winch.Next step, but level or vertical mobile winch, loop-forming cable is placed (116) under the tension force effect.As the method that another kind is selected, it is static that winch can keep, and move one or more adjusting pulleys.Among Fig. 4 A-4C example has been shown, wherein loop-forming cable is subjected to the tension force effect at its proximal part and distal portions two places.Have winch and/or regulate the midway location of pulley, the proximal part of loop-forming cable changes between strong and weak tension force herein, with moving heavy object near or leave building.Continue then to connect weight (120) to loop-forming cable in the other zone of building lot.As mentioned below, this has multiple diverse ways operation.For example, weight may be the casing with a suspension hook, and this suspension hook removably is connected on the ring that is permanently affixed on the loop-forming cable.
Operation continues, drive winch, promote the upper floor of the weight of attaching to building, (for example near predetermined upper floor) stops winch (124), mobile then winch when weight arrives predetermined altitude, reduce the tension force in the loop-forming cable, thereby make suspension heavy weight near the building sidewall, if needed, finally contact and rest in (128) on the sidewall.Release as mentioned, also can select the tension force (thereby mobile suspension heavy weight is near building) in other method minimizing loop-forming cable, for example referring to Fig. 4 A-4C.
Next, with reference now to Fig. 8, unloading equipment or personnel are to upper floor.As selection, also can load the evacuee, for example be loaded in the casing that is connected in loop-forming cable (132), if needed, when casing can be fixed on the upper floor during in loading and unloading.In case finish loading and unloading, just continue mobile winch, be the tension force that increases in the loop-forming cable specifically, thereby mobile suspension heavy weight leave building sidewall (136).In addition, also can select the tension force in other method increase loop-forming cable (being installed in the system), for example referring to Fig. 4 A-4C.When leaving the building sidewall, the weight of decline is not subjected to stop from outstanding anything of building sidewall.Drive winch with reversing sense then, the decline suspension heavy weight, arrive the other zone (140) of ground when weight arrives predetermined low layer or descends always, behind unloading all personnel, evacuee or equipment (144), further unload other parts of weight from the loop-forming cable.
Can repeat aforesaid operations 124-144 near other required upper floor.After the use of finishing native system, mobile winch and/or adjusting pulley shed the tension force (152) on the loop-forming cable, remove loop-forming cable (156) from winch thereafter.Then winch is carried go back to warehouse or maintenance place, as fire house (160).At last, deposited loop-forming cable,, or be fixed on the sidewall (164) of building for example with in the housing of loop-forming cable backrush to the roof in order to standby.
Though the operation of above-described diagram of circuit is continuously orderly, this does not also mean that in all cases and must carry out aforesaid operations in order.For example, in operation 112, (if also not having the closed annular cable), the closed annular cable can twine loop-forming cable before the winch, rather than twines after the action.Also in another example, before placing loop-forming cable under the tension force effect attached weight to loop-forming cable (operating 120 and 116).Change in order to obtain these, it is necessary that the design weight is attached to loop-forming cable with the different mode of design with weight.For example, weight comprises a different casing 33, and shown in Fig. 5 A, wherein a rigidity supporting structure 38 is connected on the loop-forming cable 28 as parts of casing.Also can select other form design casing, for example substitute described rigid construction 38 with the flexible steel cable of multiply.
With reference now to Fig. 9,, it shows a kind of lateral plan of technology of stable casing 30.In the present embodiment, casing 30 keeps stable with respect to building 500, has used a kind of mechanism that comprises the cable 102 that leads, and this guiding cable is attached on the sidewall 508 of building, and arranges along the sidewall between upper sheave and the ground, as shown in the figure.First guide rope 106 is subjected to the tension force effect, and the cable 102 that will lead is connected on the casing 30.Guide rope 106 is by sliding on the ring 104 edge guiding cables 102.Another ring 108 is fixed on the bottom of casing 30, and it is passed by described guide rope.Guide rope 106 keeps tension force by weight 110, and weight 110 drags continuously and draws casing 30 near building 500, and makes it keep stable with respect to building and loop-forming cable 28.When by winch 24 mobile box 30 up and down the time, ring 104 slides up and down along guiding cables 102, constantly promotes casing 30 near building 500.
Except the mechanism that the preceding paragraph is described, casing 30 can further keep stable with respect to the distal portions of loop-forming cable 28.Can realize along moving on the distal portions of loop-forming cable 28 by far-end becket bridle 105, as shown in the figure.The mode of operation of this mechanism is identical with another embodiment basically, draws because weight 110 drags down along far-end guide rope 107 continuously, promotes the distal portions of casing 30 to loop-forming cable 28.In such embodiments, the tension force that acts on the guiding cable 102 should be preferably more than the tension force that acts on the loop-forming cable distal portions.Notice, substitute and use single weight 110, can manually implement tension force, also can pass through other form, as a plurality of weights that separate by the personnel in the casing 30.
Aforementioned stable mechanism can not influence by mobile winch 24 make casing 30 near or leave the ability of building sidewall 508.Therefore, as shown in figure 10, by the winch 24 that moves up (by means of the chute 25 that promotes on the vehicle 26), casing 30 moves up and always leans against on the building sidewall 508, makes the proximal part of loop-forming cable 28 produce certain slack like this, as shown in the figure.
Should be noted that in Figure 10, the distal portions of loop-forming cable 28 keeps tension state between winch 24 and pulley 22.This tension force is formed by weight (with weight 110) the drawing loop-forming cable 28 of casing 30, yet the distal portions of loop-forming cable 28 is by the friction force support of the drum surface on the winch 24.Relevant loop-forming cable, pulley and winch have hereinafter been described, and the detail section of other parts of native system.
Casing
The various embodiment of the invention described above can enter its upper floor from the building outside, and not need required sleeve of typical cargo lift or guide rail.Here there is dissimilar casings to be attached on the loop-forming cable of native system.They can be the cage structures of perfect rigidity, also can be made up of the platform that has flexible net.Yet the portability of casing is considered to influence key element of its design-calculated.Particularly, more than one casing need be sent to architectural with winch.Casing also can be selected to store in Architectural Services Department, rather than transports to Architectural Services Department.In addition, casing should allow preferably that the evacuee passes in and out fast.Also have, if the outstanding part of building hindered casing arrive building wall (even casing move after the as close as possible building), the passage that a definite form should be provided for example, is integrated on the casing to casing.Also requiring has closable inlet on the casing.
As mentioned below, an enhancing ring is arranged on the loop-forming cable, by means of safety hook, the casing top can be attached on the described enhancing ring.This allows casing can freely wave when suspention, and it waves the length that depends on the rope that suspension hook is linked to each other with the top of casing main structure.Some action is necessary, with manual help casing location, is used for loading and unloading.As a top bonded assembly alternative, connection cord can directly be attached on the base plate of casing.In this case, by the tension force in the loop-forming cable that promotes casing, casing is stabilized in its top.Though do not illustrate in the accompanying drawing, wheel should be fixed on the casing bottom, preferably has damper brake, is convenient to move on the ground.
Also can on casing, design overhanging ladder, grapple, crowded control convenience, camera, battery, electrical generator, pump, stretcher, wire installation, saw and cutting machine.
Cable
Cable is preferably selected steel rope for use, and the selection of its size and model is based on the cargo capacity of native system and the structure of traction design and pulley.The rope footpath is big more, and the goods of carrying is heavy more, and usually, the less steel rope in rope footpath is easy to handle, and cost is lower, and requires less pulley.As an example, the rope of steel rope footpath can be chosen in rate of braking and be about 15, and 3/8 inch of 000lbs and rate of braking are about 26, the steel rope between 1/2 inch of 000lbs.When being used to succour, when succouring as fire brigade, all examples preferably use steel rope size same, that choose in advance in the native system.Certainly, these only are the sizes in the example, therefore should suitably select different sizes for use in practice.
Annular wire rope should be walked around the top pulley, and has sufficient length and can arrive the building lot near zone.For example, under the situation of single pulley embodiment, the length of annular wire rope is that the twice of vertical distance between pulley and ground is added 10% height, and weight is unhinderedly moved along building, and is as indicated above.
Winch
Winch can be the winch of a traction, its working power and damper brake act directly on the loop-forming cable distal portions, and its medium power is to be used to drag draw distal portions, thereby promotes the weight that is attached on the proximal part, and damper brake is used to discharge distal portions, and then the decline weight.All attached weight (as the casing among Fig. 3 B 30 and 32) in the distal portions of loop-forming cable and proximal part two places wherein, two direction traction drive promote and the heavy weight casing that descends before and after the winch.Hereinafter described the power demand of winch in this paper example, wherein had the mixed weight of hanging basket and 5000 pounds of (lbs) unit weights thereof for the single casing of hanging basket, upwards the speed of operation is 500 feet of per minutes.The theoretical power of potential demand is 75 horsepowers in this case.If estimate that overall system efficiency is 50%, for fluid power system, the power of demand will be 150 horsepowers so.Certainly, if speed and unit weight are reduced to 250 feet of per minutes and 2500 pounds respectively, so required horsepower is reduced to and is lower than 40 horsepowers.Use the hydraulic-driven of variable volume, native system will promote the heavy weight weight with low speed, and promote the light weight weight at full speed.By suitably braking effectively, heavy weight will descend with predetermined speed, not depend on the horsepower of system.The driving of native system comes from from winch is told a part of power by the same vehicle (as fire extinguishing tanker) of anchoring, or comes from the driving engine or the trailer of the independent fire brigade that reaches the spot, and this will depend on that winch transports in which way.
Can use the motor hoist drive system replacement liquid pressing system of improvement, it provides power by portable engine.Notice that the ability of the speed control of providing is provided for hydraulic pressure and motorized motions, and the power that promotes weight and brake when being used to descend weight.
Can use multiple technologies provide the traction promote and the cable that descends on weight.An example is to implement enough hydraulic couplings to be subjected on the pressure roller in (winch) that twine cable, produces required tractive force when cable passes under haulage drum.Another technology is to use and turns to sheave or deflector, increases contact radius, and bigger tractive force is provided, and acts on pressure required on the cable simultaneously and reduces.Also have another technology to provide cut-back pressure on the proximal part of discharged " tail rope " or loop-forming cable, increasing traction; Preferentially utilize the self-excitation that is subjected to pressure roller, its application force is generated by the tension force that suspension heavy weight produces.The reverse tension of this tail rope is walked generation by cable between the power drum of one group of torque control.Another kind method is to pass between the two halves that separate the sheave pressurized.Can produce pressure by spring or hydraulic cylinder, if needed, can increase the reverse tension of tail rope.The traction principle of separating sheave can preferentially be used for the embodiment (Fig. 3 B) of sided configuration.
Notice that winch can be made up of the traction sheave (not shown) that keeps flat, promptly with the truck base level of vehicle 26, referring to Fig. 1.Hauling block can pivot around a fixing pressure roller (not shown) that is subjected to.Deflection sheave (also not shown) guiding is positioned at the both sides rope of loop-forming cable to upper sheave 22.In such an embodiment, upper sheave preferably is parallel to the sidewall (rather than vertical configuration as shown in Figure 1) of building.Winch also has the tail load ability, so its contrast carries end of cable to pass winch, and it can be opened and the annular section of cable is installed.Also have other the winch structure and the locate mode of pulley.
Winch can be the part of the control unit (not shown) of total system, and it can place other for example can being built by any position that fire brigade arrives of building.Winch and the pulley layout that is in line is with the wall of building meet at right angles (Fig. 3).Yet, when square position does not meet actual time, winch also can be built into an oblique angle.Preferably, because design each building required winch and pulley in advance, so in the architectural appropriate length that steel rope is provided.
Cable connects
The casing that is attached on the cable can move up and down, preferably operation between below the top of pulley and the winch.These are connected to casing on the cable and needn't cross pulley or move under the winch.Therefore, suitable select location place uses the regulation of multiple pattern to connect on cable, does not have relevant gap.
Cable can be cut into single, continuous one section, it has the double length of distance between the assigned address (as the ground of building) from the pulley to the winch.One end of one cable that cut by attaching to of ring is used to connect its two ends at the hook with safety tong of the other end, forms an osed top annular.Ring and hook with safety tong are configured on the cable that has sleeve.Also have a fixing fitting on the ring and be used to hang casing (or other weight) to cable.
As another replacement scheme, loop-forming cable can be two independent, continuous parts, and the length of each part is half of distance the operating position of winch on the ground from pulley to building, disposes identical ring and hook in the end of each part.Also provide the fixed position, be used for attached two weights (as casing 30,32), as in the embodiment of sided configuration, using in the opposite end of cable.
Bindiny mechanism's connect box that other is also arranged is to cable, and it can be the quick operated rope clamp, is similar in the skiing elevator system to connect hanging basket to construction of wire rope.
Pulley
Using at least one pulley or sheave in native system, is two pulleys or sheave as a rule.Use the advantage of two sheaves to be, when using two hanging baskets in sided configuration embodiment, there is the gap in hanging basket when mobile each other, and needn't provide the gap by mobile winch.In double grooved pulley embodiment (referring to Fig. 6 A-6C), sheave is rotatable, so the wheel of pulley is arranged in juxtaposition on the tension direction of steel rope.If building designers or building building-owner like two sheaves to arrange, and when being not easy to be seen, can use deflection sheave.
Sheave in a different manner can be forever or is fixed to provisionally on the structure of building.The attitude of building designers at the outer shape of architectural native system depended in this selection.For example, sheave is installed on the davit, and it can arrive the roof height at an easy rate, particularly when needs clear a fence.If needed, davit can be out of sight superimposed, and the automatic erect of the tension force in the steel rope they.In addition, has the rope hook on the opening of railing.
The frame that supports sheave can be suspended in the sidewall of building, and leans against on the wall of building.Sheave also can be installed on the outrigger, and this outrigger protrudes from roof, or protrudes from the low elevation angle.When tension force acted on steel rope, these outriggers can be and are rigidly connected or stretch out configuration a little and outwards slide.Preferentially be used for having one or two davit on the device of fire brigade, it is enough high and enter the roof plane easily.
According to one embodiment of present invention, the book that should furnish an explanation is operated the system that arrives from the outside of tier building upper floor, and is with reference to one or more examples among the figure 1-10, as indicated above.For example, these specification sheetss can offer the fire fighter, and they will react to the emergency help of relevant building.
