[0036] The aviation oil supply is an important part of the civil aviation business system, and provides strong support for the development of China's civil aviation industry. When refueling the aircraft parked on the apron, the refueling operator drives the pipeline refueling truck at a low speed along the designated route, stops steadily under the wing, and maintains a safe distance from the aircraft and other operating equipment. The wheel stop is placed to ensure that the vehicle does not move during refueling, and the static electricity guide device is connected to eliminate the risk of static electricity fire.

[0037] However, since the aircraft fueling port is relatively high, the aviation fueling hose is generally wound on the hose reel on the refueling truck. When refueling the aircraft, the fueling hose wound on the hose reel is generally unwound first, and then the aircraft is refueled. However, in the prior art, the hose wound on the hose reel is generally unwound manually. For example, when a single worker refuels the aircraft, the hose wound on the reel needs to be unwound first. The hose needs to be pulled out of the hose reel and unwound, and then pulled to the fueling port for refueling operation. For another example, when two workers refuel the aircraft, one worker needs to gradually unwind the hose wound on the hose reel, and the other worker needs to gradually hold and pull the hose to the fueling port for refueling. The two aforementioned refueling methods both require manual unwinding, and the refueling operation steps are more, and manual unwinding is intermittent, which undoubtedly greatly reduces the unwinding efficiency of the hose, so that the aircraft cannot be refueled in time, and there is a risk of delaying the flight.

[0038] To solve the above problems, the utility model provides a kind of for aviation oil delivery hose's unfolding device, when the aircraft parked on the tarmac needs to be refueled, staff first drive pipeline refueling truck to aircraft parking, then the end of hose wound on pipeline refueling truck hose reel is placed on the profiling component of the device, then the position in height direction is adjusted by adjusting the compression assembly, to realize the clamping of hose, prevent hose from slipping relative to profiling component or falling from profiling component during unwinding.Then open driving component, driving component drives transmission component to rotate profiling component around rotating shaft, gradually release the hose wound on hose reel, without manually unwinding the hose wound, improve the efficiency of hose unwinding, when refueling aircraft, avoid the problem of delayed flight due to hose unwinding not in time.

[0039] To make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0040] As Figures 1-4 Indicated, first the overall structure of this for aviation oil delivery hose's unfolding device provided by the embodiment is described.

[0041] This for aviation oil delivery hose's unfolding device 1 includes: support frame 10 that supports hose during hose unwinding, driving assembly 20, and profiling assembly 30 and compression assembly 40 on both sides of hose during unwinding.

[0042] Wherein, support frame 10 includes two oppositely arranged support side walls 100 and support rear wall 130 fixed on both support side walls 100, two support side walls 100 and support rear wall 130 together enclose containing space, support rear wall 130 is provided with pipeline through hole for aviation oil delivery hose to pass through, when the hose wound on hose reel needs to be unwound, the end of hose is passed through pipeline through hole, so that support rear wall 130 has support force to hose, avoid the risk of hose swinging during unwinding.

[0043] Further, in an implementable embodiment, please refer to Figure 1 Support frame 10 also includes support bottom wall 110 fixed on the bottom of two support side walls 100 in height direction H and support top wall 120 fixed on the top of two support side walls 100, and mounting bracket 60 is also fixedly installed on support top wall 120 and support bottom wall 110.By setting mounting bracket 60, when the hose wound on hose reel needs to be released, the device can be fixedly installed on the bracket of hose reel outlet end through mounting bracket 60, to facilitate the unwinding of hose.

[0044] It needs to be understood that the support frame 10 can be a box structure surrounded by rectangular connecting plates, and the two support side walls 100 are two rectangular connecting plates arranged along the width direction W and opposite to each other along the height direction H, the support back wall 130 is a rectangular connecting plate fixedly arranged between the two support side walls 100 and located on the same side of the two support side walls 100, the support top wall 120 is a rectangular connecting plate fixedly installed on the top of the two support side walls 100 and placed along the plane, and the support bottom wall 110 is a rectangular connecting plate fixedly installed on the bottom of the two support side walls 100 and placed along the plane.

[0045] Further, the driving assembly 20 includes a driving component 21 fixed to the support frame 10, and a transmission component 22 located in the accommodation space and transmissionally connected to the driving end of the driving component 21; the profiling assembly 30 includes a profiling component 31 arranged in the accommodation space and rotationally arranged along the width direction W of the support frame 10 and around a rotation shaft parallel to the width direction W, and the profiling component 31 is transmissionally connected to the other end of the transmission component 22; by arranging the transmission component 22 and the profiling component 31 in the accommodation space, the device operates, that is, the soft tube is conveyed by driving the transmission component 22 by the driving component 21 and rotating the profiling component 31 by linkage, so as to avoid the risk of causing harm to the worker by the worker's mistake.

[0046] Further, the pressing assembly 40 extends along the direction perpendicular to the height direction H of the support frame 10 and is translationally arranged in the accommodation space along the height direction H; and the pressing assembly 40 and the profiling component 31 are located on the two sides of the aviation fuel conveying soft tube in the pipeline through hole along the height direction H, and the pressing assembly 40 is closer to the support back wall 130 than the profiling assembly 30; when the device operates, the soft tube wound on the pipeline tanker soft tube disc is placed on the profiling component 31 of the device, and then the position of the pressing assembly 40 along the height direction H is adjusted to realize the clamping of the soft tube, and when the driving component 21 operates, the profiling component 31 rotates by linkage and the pressing assembly 40 also rotates, so as to realize the unwinding of the soft tube without interruption in the middle, thereby improving the unwinding efficiency of the soft tube.

[0047] Further, the pressing assembly 40 is closer to the support back wall 130 than the profiling assembly 30, and since the soft tube is placed on the profiling component 31 after passing through the pipeline through hole on the support back wall 130, it can be seen that the profiling component 31 and the pressing assembly 40 are arranged in a staggered manner along the conveying direction of the soft tube, so that the resistance of the pressing assembly 40 to the soft tube is smaller under the premise of limiting and pre-fixing the soft tube.

[0048] In summary, the working principle of the unwinding device is as follows: when the aircraft parked on the apron needs to be refueled, the staff first drives the pipeline refueling truck to the parking place of the aircraft, then puts one end of the hose wound on the hose reel of the pipeline refueling truck through the pipeline through hole on the profiling component 31 of the device, and then adjusts the position of the pressing assembly 40 in the height direction H to limit and fix the hose, preventing the hose from slipping relative to the profiling component 31 or falling off the profiling component 31 during unwinding. Then open the driving component 21, the driving component 21 drives the transmission component 22 to rotate the profiling component 31 around the rotating shaft, gradually releasing the hose wound on the hose reel without interruption, improving the efficiency of hose unwinding. When refueling the aircraft, the problem of delayed flights caused by untimely hose unwinding is avoided.

[0049] It should be understood that the height direction H and the width direction W are the height direction and the width direction of the unwinding device, which have been marked in the drawings.

[0050] Further, in order to ensure the appearance of the device, and to avoid the hands of the staff from accidentally touching other components such as the transmission component 22 when adjusting the position of the pressing assembly 40 in the height direction H, the device further comprises a housing 50 fixedly installed on the support frame 10 and surrounding the receiving space of the support frame 10; the housing 50 is provided with an operation opening 51 aligned with the pipeline through hole. It should be understood that the housing 50 is fixedly installed on the support back wall 130 and the outer periphery of the support side wall 100, thereby improving the appearance of the device, and the operation opening 51 is located at the position of the housing 50 on the support back wall 130, which on the one hand facilitates the staff to operate and change the position of the pressing assembly 40, and on the other hand limits the hand operation space of the operator, thereby avoiding accidental touching.

[0051] The mechanism and arrangement of the pressing assembly 40 are further described below.

[0052] As Figures 3-5As shown, in an implementable embodiment, to adapt to different sizes of the hose, the distance between the pressing assembly 40 and the profiling assembly 30 is adjustable. The pressing assembly 40 comprises a first sliding member 41, a second sliding member 42 and a pressing roller 43; wherein the pressing roller 43 extends along the width direction W and is rotatable along a rotation axis parallel to the width direction W, one end of the pressing roller 43 is rotatably connected to the first sliding member 41 and is slidably connected to one side of the support side wall 100 through the first sliding member 41, and the other end of the pressing roller 43 is rotatably connected to the second sliding member 42 and is slidably connected to the other side of the support side wall 100 through the second sliding member 42; when the hose is unwound or wound by the device, since the pressing roller 43 extends along the width direction W and is rotatable along the rotation axis parallel to the width direction W, the pressing roller 43 can rotate relative to the hose during the movement of the hose, thereby reducing the resistance of the pressing roller 43 to the hose during unwinding. It should be understood that the rotation axis is an axis arranged at both ends of the pressing roller 43, so that the pressing roller 43 can rotate.

[0053] Further, among the pair of side wall surfaces opposite to each other of the two support side walls 100, one side wall surface is provided with a first sliding rail 1001 extending along the height direction H, and the other side wall surface is provided with a second sliding rail 1002 extending along the height direction H, the end of the first sliding member 41 is slidably fitted to the first sliding rail 1001, and the end of the second sliding member 42 is slidably fitted to the second sliding rail 1002.

[0054] Specifically, when different sizes of the hose wound on the hose disc are released by the device, the first sliding member 41 can slide along the first sliding rail 1001, the second sliding member 42 can slide along the second sliding rail 1002, and the pressing roller 43 can slide along the height direction H in linkage, so as to change the position of the pressing roller 43 in the height direction H, and further change the distance between the pressing roller 43 and the profiling assembly 31, thereby achieving the purpose of adapting to different sizes of the hose, and having the advantage of good adaptability. It should be understood that the size of the hose refers to the radial size of the hose.

[0055] Further, in an implementable embodiment, to realize that the pressing roller 43 does not slide along the height direction H after changing the position, and to quickly change the position of the pressing roller 43, please refer to Figure 5The first sliding member 41 comprises a first mounting base 410 and a first sliding base 411, and the second sliding member 42 comprises a second mounting base 420 and a second sliding base 421. The first sliding base 411 is slidingly fitted to the first sliding rail 1001. The first mounting base 410 is fixedly connected to the side of the first sliding base 411 away from the first sliding rail 1001. The first mounting base 410 is provided with a first threaded hole in the width direction W. A first compression screw is arranged in the first threaded hole. The length of the first compression screw is greater than the length of the first threaded hole.

[0056] Further, the second sliding base 421 is slidingly fitted to the second sliding rail 1002. The second mounting base 420 is fixedly connected to the side of the second sliding base 421 away from the first sliding rail 1001. The compression roller 43 is arranged in the width direction W of the support frame 10. One end of the compression roller 43 is rotatably connected to the first mounting base 410. The other end of the compression roller 43 is rotatably connected to the second mounting base 420. The second mounting base 420 is provided with a second threaded hole in the width direction W. A second compression screw is arranged in the second threaded hole. The length of the second compression screw is greater than the length of the second threaded hole.

[0057] Specifically, when the position of the compression roller 43 in the height direction H is adjusted, the first sliding base 411 is slid on the first sliding rail 1001, and the second sliding base 421 is slid on the second sliding rail 1002, so that the positions of the two ends of the compression roller 43 are quickly changed. The hose is limited and pre-fixed on the profiling member 31, which facilitates the subsequent release of the hose wound on the hose disc.

[0058] More specifically, after the position of the compression roller 43 is changed, the first compression screw is gradually tightened into the first threaded hole, so that the first compression screw compresses the first mounting base 410, and then the first mounting base 410 compresses the first sliding base 411. The second compression screw is gradually tightened into the second threaded hole, so that the second compression screw compresses the second mounting base 420, and then the second mounting base 420 compresses the second sliding base 421. Finally, the position of the compression roller 43 is fixed. When the position of the compression roller 43 needs to be changed, the first compression screw and the second compression screw only need to be loosened.

[0059] Further, the structures and arrangement modes of the driving assembly 20 and the profiling assembly 30 are explained below.

[0060] Specifically, as shown in FIG. 1, the driving assembly 20 comprises a driving motor 21, a driving belt 22, a driving pulley 23, a first driving pulley 24, a second driving pulley 25, a third driving pulley 26, a fourth driving pulley 27, a fifth driving pulley 28, a sixth driving pulley 29, a first driving belt 221, a second driving belt 222, a third driving belt 223, a fourth driving belt 224, a fifth driving belt 225, and a sixth driving belt 226. Figures 1-3As shown, the driving assembly 20 comprises a driving component 21 fixed on the support frame 10, and a transmission component 22 located in the receiving space and transmissionally connected with the driving end of the driving component 21. The profiling assembly 30 comprises a profiling component 31 extending along the width direction W of the support frame 10 and rotationally arranged in the receiving space about a rotation axis parallel to the width direction W, and the profiling component 31 is transmissionally connected with the other end of the transmission component 22.

[0061] Optionally, in an implementable embodiment, to ensure the safety of the device operation, the driving component 21 comprises a pneumatic motor 210 fixed on the upper surface of the support top wall 120, and a speed reduction member 211 located in the receiving space and fixed on the support side wall 100 and in communication with the output end of the pneumatic motor 210.

[0062] Specifically, the driving is realized by the pneumatic motor 210 circulating gas, ensuring that there is no fire source and power source near the airplane during refueling.

[0063] More specifically, the transmission component 22 comprises a belt transmission member 220 extending along the height direction H, one end of the belt transmission member 220 is transmissionally connected with the power output end of the speed reduction member 211, and the other end of the belt transmission member 220 is transmissionally connected with one side end of the profiling component 31, so as to drive the profiling component 31 to rotate about the rotation axis parallel to the width direction W.

[0064] Specifically, during the use of the device, the pneumatic motor 210 drives the speed reduction member 211 to drive the belt transmission member 220, and then the belt transmission drives the profiling component 31 to rotate, so as to realize the unfolding of the hose. It should be understood that the speed reduction member 211 can be a gear speed reducer, a worm gear speed reducer, etc., and the main purpose is to reduce the rotation speed of the pneumatic motor 210, to increase the torque output by the speed reduction mechanism, so as to improve the unfolding efficiency of the hose.

[0065] It should be further understood that the driving component 21 can also be a combination of a driving oil cylinder and a speed reduction member 211 or a combination of a driving air cylinder and a speed reduction member 211, and the design purpose is to avoid the device without fire source or power source, so as to avoid the risk of fire during the refueling of the airplane, which is not limited in the present embodiment.

[0066] Optionally, in an implementable embodiment, to facilitate the control of the working state of the driving component 21, such as Figure 1As shown, the driving component 21 further comprises a mechanical switch 212 fixedly installed on the support frame 10, the mechanical switch 212 is transmissionally connected to the air inlet valve of the pneumatic motor 210, and is used for opening or closing the air inlet valve of the pneumatic motor 210. For example, when the mechanical switch 212 is opened, the air inlet valve of the pneumatic motor 210 is opened, the pneumatic motor 210 works, and the profiling component 31 is driven to rotate, so as to unroll the hose rolled on the hose disc. When the mechanical switch 212 is closed after the hose is unrolled, the air inlet valve of the pneumatic motor 210 is closed, the pneumatic motor 210 does not work, and the profiling component 31 no longer rotates to unroll the hose.

[0067] Further, in an implementable embodiment, as shown in Figure 3 and Figure 4 As shown, the profiling component 31 comprises a profiling shaft 310 extending along the width direction W of the support frame 10, and a transmission part fixedly arranged at one side end of the profiling shaft 310, and the other end of the belt transmission member 220 is transmissionally connected to the transmission part at one side end of the profiling component 31. The transmission part can be arranged as a driven wheel coaxially arranged with the profiling shaft 310, and the driven wheel is fixedly sleeved on one side end of the profiling shaft 310.

[0068] Specifically, the belt transmission member 220 comprises a driving wheel sleeved on the power output end of the speed reduction member 211, and a transmission belt extending along the height direction H, and one end of the transmission belt is sleeved on the driving wheel, and the other end is sleeved on the driven wheel.

[0069] More specifically, when the device works, the pneumatic motor 210 drives the speed reduction member 211 to rotate, and the driving wheel is driven to rotate, the transmission belt is driven to rotate, and finally the driven wheel is driven to rotate to unroll the hose rolled on the hose disc.

[0070] Further, in an implementable embodiment, when the profiling shaft 310 conveys the hose, in order to limit the hose in the width direction W, a profiling part adapted to the outer peripheral contour of the aviation oil conveying hose is formed in the middle part of the profiling shaft 310; in the cross section taken along the axial direction of the profiling shaft 310, the radial dimension of the two ends of the profiling shaft 310 is larger than that of the middle part.

[0071] From the above, the working principle of the unwinding device 1 for the aviation oil delivery hose is that when the aircraft parked on the parking apron needs to be refueled, the staff first drives the pipeline refueling truck to the aircraft parking place, then places one end of the hose wound on the pipeline refueling truck hose reel through the pipeline through hole on the profiling shaft 310 of the device, then adjusts the position of the pressing roller 43 in the height direction H to realize the limiting and pre-fixing of the hose, and prevent the hose from slipping relative to the profiling member 31 or falling off the profiling member 31 during unwinding. Then open the speed reducer 211, so that the pneumatic motor 210 drives the speed reducer 211 to drive the driving wheel to rotate, the driving wheel rotating drives the transmission belt to drive the driven wheel to rotate, and finally the driven wheel rotating drives the profiling shaft 310 to rotate to realize the unwinding of the hose wound on the hose reel, without interruption in the middle, improving the efficiency of the hose unwinding, and avoiding the problem of delaying the flight due to the untimely unwinding of the hose when refueling the aircraft.
