Be to adopt bateau or buoyancy tank in the present existing technology as buoyancy aid, pontoon bridge that these buoyancy aids are made or floating road couple together with stiff frame or steel plate, its volume and weight is bigger, sets up difficultly, and they all can not be held concurrently and set up on the ground at the water surface, moorland, rubble; The existing pontoon bridge made from microscler rubber bulb be air filling type, but the blowing pressure is little, and supporting capacity is little, easily broken, and rolling need be used manpower; Existing temporary wharf is used the landing stage, but when big ship offshore is far away, just uses barge, has increased the expense of transferring and time; Now, takeoff and landing need one section ground run distance, and by land, existing runway is made with steel concrete, so landing site is very restricted; In present underwater salvage used salvaging mode such as float-type, play hanging, fill the formula of moulding etc., its pluses and minuses are respectively arranged, but common be that the activity duration is long, employ ship and auxiliary equipment is many, the total cost height; In the current Ship's Insubmeribility design, the separation methods that adopt more, after being certain cabin damage and water inflow, just with this cabin sealing, this is passive, also be equipped with a spot of ballast tank in addition, certain additional buoyancy can be provided after their drainings, still, enlarge ballast tank and will take more volume of compartment, and after a large amount of ballast tank drainings, move causing on the center of gravity of ship, unfavorable to stability, so more being used in to submersible vessels such as submarines of the way of ballast tank provides buoyancy, and the large ship of the water surface needs the problem of a large amount of additional buoyancy when running into special circumstances, in fact is not resolved; Existing ship stabilization fin is formed with the rigidity wing plate, can make and can receive the structure that can support, and length has only several meters, and only when the high speed of a ship or plane, anti-rolling effect is better for this equipment, generally in, low powered all should not adopt, especially when suspending, anti-rolling effect is more little; Along with the development of aerospace cause, the salvaging and the place apparatus of space object need, and operating distance the longer the better; In existing air-supply system, directly run out with pipe, the time of connection is long, is difficult to accurate contraposition again; In existing oil slick salvaging system, the oil slick of a large amount of leakages is drawn a circle to approve with floating drum, need canoe dispensing floating drum, delineation efficient is low; Gangway ladder that existing aircraft is used or escalator adopt rigid ladder more, and it is big to take up room, and sets up inconvenience, does not generally carry; Existing helicopter rope ladder, personnel climb that to step on effort time-consuming again up and down the time, and give a kind of sense of insecurity; Existing aircraft wing adopts stiff frame, outsourcing covering to form, can not rolling, and it is big to take up room during shutdown, and resistance is big during high speed; Paddle in the rotor of existing helicopter is made with big and long whole plate, and is heavy, resistance is big, can not rolling; Existing enclosure wall, roadblock all adopt fixation means, and corral is time-consuming to be taken up an area of again, and be also bothersome during dismounting, can not immediately set up.
The objective of the invention is to overcome the shortcoming of above-mentioned all equipment,, provide a kind of and can lay rapidly and the rapid equipment of rolling by means of the pressure of working fluid, the elastic force of equipment and interaction and the balance between the extraneous power factors such as (as load).
Content of the present invention: equipment mainly is made up of two parts, can raise the hollow vortex coil spring group that trails under the pressure fluid effect, reaches the firm pressure fluid source apparatus that links to each other and pressure fluid can be provided to it of opening part with this groups of springs.Hollow vortex coil spring group of the present invention is used as the buoyancy aid use with load-carrying in some occasions, is used as extending arm in other occasions and uses with power transmission, also can make the corral barrier and use.Automatically raise under the working fluid effect and trail, auto-folder, rolling are raised and are occupied huge space when trailing under self elastic force effect, bear huge load or thrust, volume is little after the rolling, takes up an area of for a short time, and material therefor is saved manyly than existing same category of device.The pressure fluid source apparatus is for above-mentioned groups of springs provides, the blowdown presssure fluid, reach the service pressure of when this groups of springs work, being responsible for keeping fluid, this working fluid is generally with compressed air or press water, or with other gas, liquid, fluid-mixing, can be different and different according to the situation and the instructions for use of surrounding environment.
Equipment of the present invention can be used as water surface pontoon bridge, floating road, use temporary road as in the place that is unsuitable for walking or driving a vehicle, be used as between ship or the road that passes through between ship and bank, as temporary wharf, temporary runway as the aircraft that rises and falls, be used as in salvaging and the ship Counter-Flooding equipment under water and can launch rapidly so that the device of buoyancy to be provided, in the ship stabilization system, be used as to raise easily and stretch or the stabilizer equipment of rolling, in the salvaging of satellite or space object and dispensing device and in the air-supply system, be used as the extending arm device, at the power transmission telescopic boom device that is used as on the bulldozer between body and shovel head, in builing industry and in work high above the ground, be used as lifting gear, in fire-fighting and lifesaving appliance, be used as aerial ladder, in aircraft (or other flying objects), be used as gangway ladder or escalator, aboard as raising the rotor or the paddle of stretching with the wing and the helicopter of rolling, in oil slick salvaging system, be used as oil slick and draw a circle to approve device fast, in enclosure wall and roadblock are provided with, be used as the corral barrier and use (corral or setting when needed, when not required can rolling).Manyly on the water in a word use, by land, be used as extending arm in the aerial and water and use, also can be used as the utensil that a kind of barrier of corral and roadblock etc. block simultaneously and use as buoyancy aid.
The present invention is achieved in that prefabricated its size and shape and the working condition scroll spring group that adapt, hollow that will finish, this groups of springs has opening, and link together securely by opening and pressure fluid source apparatus, junction between other end faces except that opening part, upper and lower surface, side and these faces is all sealed securely, the pressure fluid that is imported into constitutes the volume space of a sealing, so that can not leaked.After the pressure fluid source apparatus starts, mechanical energy is transformed into pressure potential, promptly improved the pressure of fluid, make it the pressure of projecting environment, when the suitable fluid of pressure is imported into above-mentioned scroll spring group, just overcome the deformation energy of groups of springs and work done, this groups of springs is raised trail and heave, so just can bear external applied load or carry out its task.In useing floating road, pontoon bridge, temporary wharf, aircraft sea runway, underwater salvage, ship stabilization system, ship Counter-Flooding system as, hollow vortex coil spring group of the present invention is launched the Chang Zuowei buoyancy aid at the water surface and is used, because its inside is pressed gas abrim, therefore, huge buoyancy can be provided, personnel and vehicle can pass through in the above, become a kind of carrier.And in other occasions, as in the salvaging and place apparatus of satellite or space object, in the power transmission telescopic boom device of bulldozer, in the aerial ladder and lifting gear of various uses, aircraft with the Automatic gangway ladder device in, in the air-supply equipment, all as extending arm, with transmission power and object.As for as the wing of aircraft and the rotor or the paddle of helicopter, then be to utilize it can raise the performance of stretching easily, thereby resistance is less when aircraft and helicopter are navigated by water at a high speed forward with rolling, it also is a kind of special extending arm.When in oil slick salvaging system, being used as oil slick and drawing a circle to approve device fast, be to utilize its performance on the one hand then as buoyancy aid, on the other hand also owing to be rolled into the characteristics that the hollow vortex coil spring group of cone can be launched into arcuation or garden round rapidly, thereby contaminated waters is drawn a circle to approve rapidly, and oil slick is unlikely to spread apart so that make.When useing hoarding and roadblock equipment as, because it can launch rapidly, and certain height is arranged when heaving, therefore can be used as interim barrier and use, the working fluid of this moment can be used Compressed Gas, also available other fluids.Hollow vortex coil spring group among the present invention is when carrying out above-mentioned each task, and as near existing ready-made pressure fluid source apparatus, then it can serve as the basic building block of the said equipment, i.e. the present invention with the pressure fluid source apparatus can save.Structure of the present invention is different with purposes optionally, can make to same direction and raise the straight scroll spring group of stretching, extension, also can make and launch the hollow vortex coil spring group that the back becomes arcuation, garden round or other curve shapes, the difference of these shapes is mainly decided by the shape of its upper and lower surface, side and floor is different with the structure configuration.After finishing using, as long as drain valve is opened, elastic force by means of scroll spring group self just can be discharged the fluid in this assembly rapidly, groups of springs is also got up with regard to folding, rolling promptly simultaneously, the length that stretches depends on the length of the spring assembly after the winding, can do very longly (as hundreds of rice), decide as required, because the distance between the circle of the scroll spring group after the rolling and the circle can be very little, even contact with each other, even the volume after the very long equipment rolling also is less.Raise when this equipment uses stretch, the process of rolling is pneumatic or the process of surging, its automaticity can be very high.When buoyancy aid after needs launch or extending arm were straight shapes, then the rolling of scroll spring group partly was shaped as the garden cylindricality; When buoyancy aid after needs launch or extending arm became the garden arc, then the upper and lower surface of scroll spring group also should be the garden arc, and rolling partly is shaped as a section taper body (or garden platform); When buoyancy aid after needs launch or extending arm be other curve shape, then its upper and lower surface also should have this shape, and made the rolling part cut the taper body what the rolling afterboarding became different taperings, or the taper body is rolled up with the garden cylindrical body is mixed.Because can obtain minimum winding volume like this.Because use thin sheet metal strip (thickness is everlasting below several millimeters), the equipment materials are economized very much, even very long equipment, its deadweight is also not too big.Upon deployment, suitably improve the pressure of institute's pressurising power fluid, just can improve the supporting capacity of equipment.
The hollow vortex coil spring group that the present invention is used, when requiring it in use to have enough structural strengths and the arch that requires its cokled surface not too high, portion increases floor or lacing wire within it, and the processing (or setting heat treatment) that also should under the rolling state, formalize of the metalwork of this floor or lacing wire, so that can not hindering raising of above-mentioned scroll spring group, it does not stretch and the rolling campaign.If this lacing wire is flexible material or rigging, very little to the resistance of motion, processing then also can not formalize.
Equipment of the present invention can all be installed on the vehicle such as car, ship, so that move.
To be further introduced according to embodiment below:
The gross buoyancy that a kind of 3 meters wide, 2 meters high, 100 meters long present devices can provide after expansion is about 600 tons.When using, if interior pressure is 1kg/cm as the said equipment being used as extending arm
2During gauge pressure, its thrust can reach 60 tons, and along with the increase of cross-sectional area or internal pressure, thrust also will increase by direct ratio.
When the said equipment was taken as the hoarding use, if fill with liquid in the scroll spring group, as water, just then the downward normal pressure of this equipment has 600 tons, it also was effectively as seen useing hoarding as.
Imagine a tall and big man and climb up pontoon bridge, usually single pin lands in advancing, his one 26 centimetres rubber overshoes, its underpart with about 185 centimetres of the area that contacts
2, for so high about 1.8 meters men, general 70 kilograms of its body weight is with 30 kilograms of luggage again, and totally 100 kilograms, like this, footwear are to pressure average out to 0.54 kilograms per centimeter of bridge floor
2, promptly the interior pressure of the hollow vortex coil spring group of this equipment reaches 0.54 gauge pressure, just can be for people's walking.In fact this pressure also can reduce, because the latch plate that contacts with people's sole face, it has a bigger radian when stress deformation, when the groups of springs upper surface was subjected to the pressure of people's pin (sole) and is out of shape, also connection the distortion of surrounding area, that is to say, one bigger influence area is arranged on every side, such as the area of the conversion area of influence area and direct pressure zone is (given deformation amount) about equally, and then above-mentioned interior pressure can be reduced to 0.27 gauge pressure.
For the vehicle gap bridge similar effect is arranged also.As truck front-wheel and bridge floor contact portion, length is 20 centimetres before and after it, and wide 15 * 2=30 centimetre, the total contact area of four-wheel is 20 * 30 * 2=1200 centimetre
2, if take measures at horizontal degree (as adding cross rib), the influence area is widened, when the influence area was widened to 200 centimetres, then the gross area was 20 * 200 * 2=8000 centimetre
2, promptly interior the pressure is this equipment of 1 gauge pressure, when distortion was very little, 8 tons of rulleys can pass through.Obviously, if will increase the load-carrying of bridge vehicle, can increase the wheel subnumber (this also is to need consistent with the heavy duty of vehicle itself) of vehicle self, also can increase the interior pressure (increase of interior pressure must improve structural strength simultaneously) of hollow vortex coil spring group, reinforce bridge floor besides with the district that widens one's influence.For example, for a kind of 3 meters long, 2 meters wide vehicles, if its influence area can account for 3 meters * 2 meters half of area, then for this class vehicle of 12 tons, pressing in the equipment only needs 0.5 gauge pressure, even littler, and the bridge floor distortion is little.Therefore say the floating road that present device provided, the personnel that not only can pass through, but also P Passable heavy vehicle.
Along with the increase of internal pressure and lifting surface area, will be higher also to the requirement of structural strength, this will make the surface thickening, also lacing wire, floor need be set; The increase of surface thickness will increase its flexural stress again, therefore in that single layer structure is too thick can not meet the demands again the time, but adopt the sandwich construction of multiple-level surface, multilayer side or floor to solve, though make its gross thickness bigger, flexural stress is still less.If any a kind of cross-sectional area is the extending arm of 200 centimetres of 200 cm x, when interior pressure reaches 1 gauge pressure, if the stressed back of extending arm cross section drum becomes garden shape, it vertically bears about 50000 kilograms pulling force, the tension strength of laterally bearing is bigger, if the tensile strength allowable of employed metallic elastic material is 50 kilograms/millimeter
2, then the individual layer wall thickness of this extending arm is just passable with 0.5 millimeter.If with two-layer structure, every layer only needs 0.25 millimeters thick.If portion establishes floor and lacing wire more within it, then its degree of heaving will be controlled, but also attenuate of wall thickness simultaneously.
Calculate as can be known by above-mentioned letter, the thing that equipment of the present invention can carry thrust or normal pressure heavy and that can provide all are sizable, and its wall thickness can be done lessly.Certainly, when the individual layer wall thickness can be competent at, adopt single layer structure, because of the letter of its technology as far as possible.

Critical piece of the present invention-hollow vortex coil spring group (1) or (21) are mainly combined by scroll spring or the connection of metal spring band. It can be connected by one or a few plane scroll spring (or band) and combine, and is the example that is connected the hollow vortex coil spring group that is combined into by two scroll springs (or two metal spring bands) such as the structure of Fig. 5; It also can be by weight light and good toughness, material (such as knotwork or plastic foil, rubber membrane and composite) that hot strength is higher be connected with a small amount of plane scroll spring and combine, but a scroll spring must be arranged at least, with the hollow vortex coil spring group that guarantees to be made up enough elastic force is arranged when the rolling, and also make load-bearing surface that enough bearing capacitys are arranged when work, be to only have a scroll spring as upper surface as shown in Figure 7, remaining face is coated with sealant or with other composites, plastic foil, rubber membrane with knotwork and consists of. As shown in Figure 9, also available two scroll springs are done upper and lower surface, and floor or lacing wire can be set, and the side still consists of with side material shown in Figure 7. In order more to be grown and wider hollow vortex coil spring group, used spring band (such as spring steel band) can splice lengthening or widen. The heat treatment (or setting process) that must formalize of used metal spring material (or band) is so that it becomes the scroll spring with enough elastic force. Depending on connecting the difference of combined situation, this setting heat treatment (or setting is processed) can be carried out before connecting combination, or carries out after connecting combination. For example, with the situation of fiber knotwork or plastic foil, rubber membrane combination, because these materials can not be high temperature resistant, so the metal spring material must perform setting heat treatment before connecting combination. Hollow vortex coil spring group after the combination resembles a microscler hollow pocket when rolling not, except opening part, other each faces, such as end face and upper surface (part 7), lower surface (8) and side (9), and the junction between these faces all sealed securely, and its opening is in order to couple together securely with pressure fluid source apparatus (or by one section adapter). When rolling, the plate of side and floor all must folding, rollings, and material will produce bigger bending stress when stretching with rolling raising. When the requirement of strength to equipment higher, and wall thickness is can not be too thick the time, the metallic elastic material and the nonmetallic materials that form hollow vortex coil spring group, the structure of available multilayer, reliability in the time of can increasing the equipment pressurising like this, increase the folding number of times and improve service life, namely improved the serviceability of equipment. Figure 14 is the drawing in side sectional elevation of example after folding that the side of hollow vortex coil spring group combines with sandwich construction. Sometimes also make partly corrugatedly, especially for the scroll spring group that becomes arcuation and other curve shapes after launching, its side and floor are made corrugated and can more successfully be raised and trail and rolling. The elastomeric material that forms hollow vortex coil spring group has friction at the volley, and corrosion is arranged when metal material and medium contact, and burn into scratch, cutter trade all will cause stress to concentrate, thus many stress and the service life of having reduced this material. Therefore, for improve corrosion resistance, the damage of reducing friction, and to reduce the stress of sensitive area concentrated, can be coated with coating on the surface of hollow vortex coil spring group and the surface of side or elastomeric material, or the topped film of sticking skim is to protect it. Connection between each face of hollow vortex coil spring group should be firmly, sealing, is connected available welding manner (such as roll welding, overlap welding etc.), rivet or screw connecting mode etc. between each face that metal material forms and between face and floor, rib, and is also available bonding; Being connected between nonmetallic materials and between nonmetal and metal material is multiplex bonding, or connects with securing member. Scroll spring group after the combination must pump pressure or leak detection.
Figure 10 is a device systems figure example of the present invention, and promptly hollow scroll spring group is with after the pipe-line system of pressure fluid source apparatus is connected, the sketch of pressure fluid generation, discharging, storage and system's control.Handle adjuster 11 prime mover 12 started, drive compressor (or pump) 13, with after the pressurized with fluid of inspiration by valve 14 and valve 17, enter hollow vortex coil spring group 1(or 21), just can make part 1(or 21) raise and trail.After system pressure is higher than rated value, be warranty element 1(or 21) safe in utilization, safety valve 18 will work, and discharge a part of fluid automatically, make pressure recover normal after, safety valve 18 cuts out again.When the pressure on the pipeline is higher or on the low side, can handles prime mover 12 by adjuster 11 and make it to shut down or start.Represent promptly that as the dotted arrow among Figure 10 adjuster 11 can handle the rotating speed or the start and stop of prime mover according to the pressure on the pipeline.Can be when guaranteeing urgent need more promptly to scroll spring group 1(or 21) pressurising, can establish reservoir pressure device 16, before for example using valve 17 cuts out, valve 14 and valve 15 are opened, can be separately to 16 pressurisings of reservoir pressure device, in case when valve 17 was also opened, reservoir pressure device 16 and compressor 13 were simultaneously to hollow vortex coil spring group 1(or 21) the discharge pressure fluid, so that it more promptly launches.Another effect of reservoir pressure device is to keep-up pressure, when equipment is worked, scroll spring group 1(or 21) launches, pressure is also enough, the a large amount of fluids of conveying do not need to keep again, this moment, compressor 13 can suspend its work, when shut off valve 14 with after stopping prime mover 12, compensated in the pipe-line system a spot of sewing with the task of keeping certain pressure this moment and just finished by the reservoir pressure device.Certainly, there is not pressure stability that reservoir pressure device 16 also can keep system in certain scope, the compressor 13 that will lean on prime mover to drive, like this, the time of prime mover work will be longer.When needs rolling equipment, as long as open drain valve 19, stop prime mover 12 and shut off valve 17 simultaneously, just can be by means of part 1(or part 21) self elastic force and rolling.So the effect of pressure fluid source apparatus mainly contains: the discharge pressure fluid, so that equipment extends; Keep the pressure on the pipeline, to keep the duty of equipment; Overvoltage protection carries out safety dumping during in order to superpressure; The storage pressure fluid reaches the pressure of keeping on the pipeline for quick starting device when prime mover quits work; The completion discharging is with rolling equipment.
From the above, the hollow vortex coil spring group among the present invention is part (1) and part (21); Pressure fluid source apparatus of the present invention comprises prime mover, gas compressor (or pump), safety valve, drain valve, adjuster, each section valve and pipeline, and the reservoir pressure device.
Figure 11 is the example that has installed two pairs of equipment provided by the present invention in the both sides of ship additional.As seen from the figure, near the water surface of boats and ships, raise and launch the huge additional buoyancy that next scroll spring group 1 is provided, the anti-rolling ability and the unsinkability of these boats and ships will be improved significantly, spread over the huge buoyancy aid of the water surface as the wing, be equivalent to increase the beam, thereby Metacentre Radius is increased, restoring moment increases, and has improved the stability of this ship.Again because equipment of the present invention can promptly be raised when being badly in need of trails, so some are needed safety and stable boats and ships (as pleasure boat, passenger steamer, surveying vessel, tjemplon etc.) especially, the application of present device will make people increase the sense of security, reduce salvage loss.Under usual situation, when pulling in to shore as needs, this ship can lean on, as long as and will raise apart from this equipment of the nearer side of bank and stretch out, promptly can be used as the boat-carrying pontoon bridge to use, both convenient, do not rely on deepwater wharf again, do not account for the harbour berth, can under the situation of most of bank feelings even mud bank, carry out remote loading and unloading and upper and lower personnel and passenger, therefore after the present device extensive use aboard ship, with the transport pressure that reduces fixed quay.
