Description

Technical Field

[0001] This invention relates to the field of aviation fuel transfer technology, and more specifically to a ground fuel transfer system for interacting with aircraft. Background Technology

[0002] In the field of aviation ground support, aircraft refueling equipment is a crucial piece of ground support equipment. Its core component is the refueling truck, which is typically equipped with fuel tanks and fuel lines connected to the tanks for delivering fuel to the aircraft. To manage the long fuel lines in an orderly manner and prevent them from becoming tangled and affecting operational safety and efficiency, current technologies generally include a dedicated storage cylinder on the refueling truck for winding and storing the fuel lines. The storage cylinder is usually also equipped with a one-way locking mechanism.

[0003] Traditional storage cylinders typically have a fixed diameter, and this rigid design limits their storage capacity and cushioning ability. A one-way locking mechanism, however, allows operators to rotate the cylinder in one direction to wind and store the tubing, and its locking function prevents reverse rotation, thus maintaining the tubing's tension and neatness. However, this one-way locking mechanism presents serious safety hazards in practical applications. Specifically, if operators start or move the oil truck without properly disassembling the tubing joints after operation or in the event of an emergency, the relative displacement between the vehicle and the aircraft will instantly generate a huge pulling force on the tubing. Because the existing one-way locking mechanism cannot be effectively released in an emergency, the storage cylinder remains locked and cannot rotate freely to release the tubing length, meaning all the pulling force is borne entirely by the tubing body and its joints. This rigid force transmission method makes it easy for the oil pipe to be overstretched at its connection with the joint or at the weakest point of the pipe body, eventually leading to oil pipe breakage or joint loosening, causing fuel leakage accidents, which not only cause economic losses and environmental pollution, but also pose a direct threat to the safe operation of the airport.

[0004] Therefore, in view of this, the inventors proposed a ground-based fuel delivery system for interaction with aircraft to solve the aforementioned technical problems. Summary of the Invention

[0005] The purpose of this application is to provide a ground-based fuel delivery system for interaction with aircraft, in order to solve the problems of existing fixed-diameter storage cylinders having limited storage capacity and buffering capacity, and the inability of the one-way locking mechanism to be released in emergency situations, which makes the fuel pipe prone to breakage or loosening of the joint due to the inability to release the length when subjected to huge reverse pulling force, thus easily causing fuel leakage accidents.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] This application provides a ground-based fuel delivery system for interacting with an aircraft, including a fuel line for delivering fuel to the aircraft, and a storage module, a guide tensioning module, and a clutch module mounted on a chassis, wherein the fuel line is wound around the storage module via the guide tensioning module.

[0008] One end of the storage module is rotatably connected to the chassis, and the other end is connected to the guide tensioning module. The clutch module is circumferentially engaged with the end of the storage module near the guide tensioning module.

[0009] When the oil pipe is stretched and the guide tensioning module is deformed, the oil pipe drives the end of the storage module connected to the guide tensioning module to move axially and cause the storage module to shrink in diameter and deform, and disengage from the clutch module, so that the storage module can freely release the oil pipe.

One end of the first hinge rod is hinged to a first shaft and the other end is movably connected to a storage block. One end of the second hinge rod is movably connected to a second shaft and the other end is hinged to a storage block.

[0013] With the first and second shafts far apart, the storage block moves closer together along the central axis of the first and second shafts via the hinge assembly;

[0014] The second shaft end is provided with a meshing connecting pin for engaging with the clutch module;

The first hinge rod is movably connected to the movable mounting block fixed on the first shaft through the sliding pin, and the second hinge rod is movably connected to the movable mounting block fixed on the storage block through the sliding pin.

[0019] Optionally, the storage block includes a connecting plate and a storage plate that are fixedly connected, and the connecting plate and the storage plate are distributed radially inward and outward along the first axis and the second axis;

[0020] The first hinge rod is movably connected to the connecting plate of the storage block;

[0021] The second hinge rod is hinged to the connecting plate of the storage block.

[0022] Optionally, the guide tensioning module includes a first mounting bracket for mounting on the chassis, and a second mounting bracket suspended by the first mounting bracket;

[0023] The first mounting bracket is provided with a first fixed guide wheel;

[0024] The second mounting bracket is provided with at least two second fixed guide wheels;

[0025] It also includes a tensioning assembly that is rotatably connected to the storage module and used to pull the tubing radially along the tubing, the tensioning assembly including a movable guide wheel;

[0026] The oil pipe is wavy and interlaced around the second fixed guide wheel, the first fixed guide wheel and the movable guide wheel. The first fixed guide wheel is located between the two second fixed guide wheels along the extension direction of the oil pipe, and the movable guide wheel is located between the two second fixed guide wheels along the extension direction of the oil pipe.

[0027] Optionally, the tensioning assembly further includes a mounting base and a guide base, as well as a guide rod, a connecting cylinder, and a return spring;

[0028] The mounting base and the connecting cylinder are respectively fixed to both ends of the guide rod, and the guide rod is slidably connected to the guide base;

[0029] The tensioning component is rotatably connected to the storage module via a connecting cylinder;

[0030] The movable guide wheel is mounted on the mounting base;

[0031] The guide seat is fixed on the first mounting bracket;

[0032] One end of the reset spring is connected to the mounting base, and the other end is connected to the guide seat.

[0033] Optionally, the first mounting bracket has at least one cantilever bracket on its side, the first fixed guide wheel is mounted on the cantilever bracket, and the second mounting bracket is suspended in the air by the cantilever bracket.

The pawl structure has a meshing connection groove for engaging with the end of the second shaft of the storage module.

[0036] The ratchet and pawl structures achieve unidirectional free rotation through the cooperation of the ratchet groove and the pawl body.

[0037] Optionally, the outer peripheral wall of the ratchet structure is provided with external teeth for meshing with the transmission mechanism to drive the ratchet structure to rotate.

[0038] Optionally, it also includes a drive module, the power output end of which is connected to the ratchet structure for transmission.

[0039] The beneficial effects of this invention are:

[0040] I. This application, by setting up a mutually cooperating storage module, a guiding tension module, and a clutch module, allows the oil pipe to move axially at one end connected to the storage module via the guiding tension module when subjected to a large tensile force (i.e., when there is relative displacement between the aircraft and the oil truck). This causes the clutch module to disengage from the storage module and release the locking state of the storage module. At this time, the storage module and the clutch module can rotate freely relative to each other, changing the original rigid resistance to pulling out the oil pipe into a flexible release of the oil pipe. At the same time, because the end connected to the storage module moves axially, the diameter of the storage module can be reduced, making the oil pipe wound on the storage module looser. In the event of a sudden tensile force, a longer oil pipe can be released.

[0041] Therefore, this application, through the coordinated linkage of the aforementioned storage module, guide tensioning module, and clutch module, can achieve a dual oil pipe release mechanism that combines the unlocking of the oil pipe from its locked state with the shrinking of the storage module's diameter. This fundamentally avoids the complete concentration of tension on the oil pipe and joint, greatly reducing the risk of oil pipe breakage and joint loosening. It also solves the long-standing safety hazard of fuel leakage caused by the inability to release force due to locking in emergency situations, which is a problem in the prior art.

[0042] II. This application achieves the aforementioned intelligent buffering function through simple and reliable purely mechanical components. The storage module adopts a unique variable-diameter structure composed of a first shaft, a second shaft, a hinge assembly, and a storage block. The radial scaling of the entire storage module is directly controlled by the axial displacement between the first and second shafts, achieving dynamic adjustment of the tubing storage length. The clutch module creatively combines the conventional one-way locking function of ratchet and pawl structures with the axial sliding displacement of the second shaft, precisely converting tubing tension into an unlocking command. The entire system achieves fully automated response from tension sensing and mechanism unlocking to diameter change without an additional power source. It features a compact structure, rapid response, and high reliability, perfectly meeting the stringent requirements of high safety and high reliability in aviation ground support.

Detailed Implementation

[0052] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0053] like Figures 1 to 7 As shown, this embodiment provides a ground fuel delivery system for interacting with an aircraft, including an oil pipe 6 for delivering fuel to the aircraft, and a storage module 3, a guide tensioning module 4, and a clutch module 5 mounted on a chassis 1. The oil pipe 6 is wound around the storage module 3 via the guide tensioning module 4.

[0054] One end of the storage module 3 is rotatably connected to the chassis 1, and the other end is connected to the guide tensioning module 4. The clutch module 5 is circumferentially engaged with the end of the storage module 3 near the guide tensioning module 4.

[0055] When the oil pipe 6 is pulled and the guide tensioning module 4 is deformed, the oil pipe 6 drives the end of the storage module 3 connected to the guide tensioning module 4 to move axially and cause the storage module 3 to shrink in diameter and deform, and disengage from the clutch module 5. The storage module 3 can then freely release the oil pipe 6.

[0056] In this embodiment, by setting up a mutually cooperating storage module 3, a guide tensioning module 4, and a clutch module 5, when the oil pipe 6 is subjected to a huge pulling force (i.e., when there is relative displacement between the aircraft and the oil truck), the oil pipe 6 will be pulled by the guide tensioning module 4 to move the end of the storage module 3 connected to the guide tensioning module 4 axially, so that the clutch module 5 is disengaged from the storage module 3, and the locking state of the storage module 3 is released. At this time, the storage module 3 and the clutch module 5 can rotate freely relative to each other, changing the original rigid resistance to pulling out the oil pipe 6 into the flexible release of the oil pipe 6. At the same time, since the end of the storage module 3 connected to the guide tensioning module 4 moves axially, the diameter of the storage module 3 can be reduced, making the oil pipe 6 wound on the storage module 3 looser, and a longer oil pipe 6 can be released when the oil pipe 6 is subjected to a sudden pulling force.

[0057] Therefore, this embodiment, through the coordinated linkage of the aforementioned storage module 3, guide tension module 4, and clutch module 5, can technically achieve the coordinated release mechanism of the oil pipe 6 by unlocking the locked state and shrinking the diameter of the storage module 3. This fundamentally avoids the complete concentration of tension on the oil pipe 6 and the joint, greatly reducing the risk of oil pipe 6 breakage and joint loosening, and solving the long-standing safety hazard of fuel leakage caused by the inability to release force due to locking in emergency situations in the prior art.

[0058] In this embodiment, an oil tank is also provided on the chassis 1, and the oil inlet end of the oil pipe 6 is connected to the oil tank.

[0059] In this embodiment, the storage module 3 includes a first shaft 31 and a second shaft 32 arranged coaxially, as well as at least one hinge assembly 33 and a storage block 34.

[0060] The storage block 34 and the hinge assembly 33 are distributed around the first shaft 31 and the second shaft 32.

[0061] The hinge assembly 33 includes a first hinge rod 331 and a second hinge rod 332 that are rotatably connected. One end of the first hinge rod 331 is hinged to the first shaft 31 and the other end is movably connected to the storage block 34. One end of the second hinge rod 332 is movably connected to the second shaft 32 and the other end is hinged to the storage block 34.

[0062] With the first shaft 31 and the second shaft 32 far apart from each other, the storage block 34 approaches along the central axis of the first shaft 31 and the second shaft 32 via the hinge assembly 33;

[0063] The second shaft 32 has a meshing connecting pin 321 at its end for engaging with the clutch module 5;

[0064] The storage module 3 is fixedly connected to the guide tensioning module 4 through the end of the second shaft 32.

[0065] In this embodiment, when the first shaft 31 and the second shaft 32 move away from each other, the included angle between the first hinge rod 331 and the second hinge rod 332 increases. This causes the ends of the first hinge rod 331 and the second hinge rod 332 away from the central axis of the first shaft 31 and the second shaft 32 to extend inward. This, in turn, causes the storage block 34 to move in the direction of the central axis of the first shaft 31 and the second shaft 32, thereby reducing the diameter of the entire storage module 3. The oil pipe 6 wrapped around the storage block 34 of the storage module 3 will be reduced due to the reduction in diameter. The reduced diameter of the housing module 3 becomes loose, which is conducive to the rapid release of the oil pipe 6. In this embodiment, the first shaft 31 is rotatably connected to the chassis 1 through the frame, and the second shaft 32 is rotatably connected to the guide tensioning module 4. When the oil pipe 6 is subjected to a pulling force, the oil pipe 6 can be pulled away from the first shaft 31 by the guide tensioning module 4. At the same time, the engagement state between the second shaft 32 and the clutch module 5 is simultaneously released, so that the rotation of the oil pipe 6 released by the housing module 3 will no longer be restricted by the clutch module 5.

[0066] In this embodiment, the storage module 3 further includes a fixed mounting block 36 and a movable mounting block 35;

[0067] The first hinge rod 331 is hinged to the first shaft 31 through the fixed mounting block 36, and the second hinge rod 332 is hinged to the storage block 34 through the fixed mounting block 36.

[0068] The movable mounting block 35 is provided with a groove 351 and a sliding pin 352 slidably disposed in the groove 351. The first hinge rod 331 is movably connected to the movable mounting block 35 fixed on the first shaft 31 through the sliding pin 352. The second hinge rod 332 is movably connected to the movable mounting block 35 fixed on the storage block 34 through the sliding pin 352. In this embodiment, by setting a fixed mounting block 36 and a movable mounting block 35, and providing a groove 351 in the movable mounting block 35, the groove 351 is elongated and its length direction is parallel to the axial direction of the first shaft 31 and the second shaft 32, thereby allowing the second shaft 32 to move smoothly along its axial direction.

[0069] In this embodiment, the storage block 34 includes a connecting plate 341 and a storage plate 342 that are fixedly connected. The connecting plate 341 and the storage plate 342 are distributed radially inward and outward along the first axis 31 and the second axis 32.

[0070] The first hinge rod 331 is movably connected to the connecting plate 341 of the storage block 34;

[0071] The second hinge rod 332 is hinged to the connecting plate 341 of the storage block 34. This implementation is both horizontal and vertical. A fan-shaped annular side plate is also provided between the storage plate 342 and the connecting plate 341, so that the storage plate 342 and the connecting plate 341 can be connected into one piece through the fan-shaped annular side plate. The fan-shaped annular side plate can increase the storage diameter of the entire storage module 3, ensuring that the storage length of the oil pipe 6 is sufficient. At the same time, with the same storage angular velocity, a higher storage linear velocity can be ensured, improving the storage efficiency of the oil pipe 6.

[0072] In this embodiment, the guide tensioning module 4 includes a first mounting bracket 41 for mounting on the chassis 1, and a second mounting bracket 42 suspended by the first mounting bracket 41.

[0073] The first mounting bracket 41 is provided with a first fixed guide wheel 412;

[0074] The second mounting bracket 42 is provided with three second fixed guide wheels 421;

[0075] It also includes a tensioning assembly 43 that is rotatably connected to the storage module 3 and is used to pull the oil pipe 6 radially along the oil pipe 6. The tensioning assembly 43 includes a movable guide wheel 432.

[0076] The oil pipe 6 is wavy and interlaced around the second fixed guide wheel 421, the first fixed guide wheel 412 and the movable guide wheel 432. The first fixed guide wheel 412 is located between the two second fixed guide wheels 421 along the extension direction of the oil pipe 6, and the movable guide wheel 432 is located between the two second fixed guide wheels 421 along the extension direction of the oil pipe 6.

[0077] In this embodiment, by setting the guide tensioning module 4, it can guide the storage of the oil pipe 6. At the same time, when the oil pipe 6 is subjected to a large pulling force, the oil pipe 6 can pull the tensioning component 43 to move through the movable guide wheel 432, thereby driving the second shaft 32 away from the first shaft 31.

[0078] In this embodiment, three second fixed guide wheels 421 are provided. The oil pipe 6 is wound in a W-shape within the entire guide tensioning module 4. In some embodiments, the first fixed guide wheel 412 can be removed, and only two second fixed guide wheels 421 are provided, so that the winding state of the oil pipe 6 is V-shaped. However, if only two second fixed guide wheels 421 are provided, false triggering is likely to occur. If too many first fixed guide wheels 412 and second fixed guide wheels 421 are provided, the oil pipe 6 may have difficulty pulling the tensioning component 43, making it difficult for the second shaft 32 to be triggered away from the first shaft 31. This leads to the problem of the storage module 3 having a reduced diameter and the engagement state between the clutch module 5 and the storage module 3 being difficult to disengage.

[0079] In this embodiment, the tensioning assembly 43 further includes a mounting base 431 and a guide base 434, as well as a guide rod 433, a connecting cylinder 435 and a return spring 436;

[0080] The mounting base 431 and the connecting cylinder 435 are respectively fixed to the two ends of the guide rod 433, and the guide rod 433 is slidably connected to the guide base 434;

[0081] The tensioning component 43 is rotatably connected to the storage module 3 via the connecting cylinder 435;

[0082] The movable guide wheel 432 is mounted on the mounting base 431;

[0083] The guide seat 434 is fixed to the first mounting bracket 41;

[0084] One end of the return spring 436 is connected to the mounting base 431, and the other end is connected to the guide seat 434. By setting the guide seat 434, the mounting base 431, the guide rod 433 and other structures, the tension direction of the second shaft 32 can be restricted. The return spring 436 can re-engage the storage module 3 with the clutch module 5 after the tension force on the oil pipe 6 is reduced, and the guide tensioning module 4 can be switched back to a state where it can only rotate in one direction to store the oil pipe 6.

[0085] In this embodiment, the first mounting frame 41 is provided with a cantilever frame 411 on its side, the first fixed guide wheel 412 is disposed on the cantilever frame 411, and the second mounting frame 42 is suspended in the air by the cantilever frame 411.

[0086] In this embodiment, the clutch module 5 includes a seat 51 disposed on the chassis 1, a ratchet structure 52 disposed on the seat 51, and a pawl structure 53 disposed within the ratchet structure 52.

[0087] The ratchet structure 52 has a ratchet groove 522 for cooperating with the pawl structure 53. The outer periphery of the pawl structure 53 has a plurality of pawl bodies 532 that cooperate with the ratchet groove 522. The pawl structure 53 has a meshing connection groove 531 for meshing with the end of the second shaft 32 of the storage module 3.

[0088] The ratchet structure 52 and pawl structure 53 achieve unidirectional free rotation through the engagement of the ratchet groove 522 and the pawl body 532. By setting the ratchet groove 522 and the pawl body 532, the clutch assembly is only limited in one direction after being fitted onto the second shaft 32 of the storage module 3. For example, after the pawl structure 53 is fitted onto the second shaft 32 through its meshing connection groove 531 and engages with its meshing connection pin 321, when the ratchet structure 52 rotates clockwise, the ratchet structure 52 will push the pawl structure 53 to rotate clockwise through the ratchet groove 522 and the pawl body 532 of the pawl structure 53, thereby driving the second shaft. When the body 32 rotates clockwise, the storage module 3 is in the state of storing the oil pipe 6. When the drive motor does not drive the ratchet structure 52 to rotate clockwise, when the storage module 3 has a tendency to rotate counterclockwise to release the oil pipe 6, the storage module 3 will drive the pawl body 532 to rotate counterclockwise through the second shaft 32. The ratchet groove 522 of the ratchet structure 52 will resist the counterclockwise rotation tendency of the pawl body 532. At this time, the release state of the oil pipe 6 is locked unless the oil pipe 6 is subjected to a huge pulling force, which will cause the engagement state between the second shaft 32 and the pawl body 532 to be released.

[0089] In this embodiment, the meshing connecting pin 321 provided on the second shaft 32 and the meshing connecting groove 531 of the pawl structure 53 can be respectively set as spline and groove or other mechanical structures that cooperate with each other, as long as the two can be mutually limited in the circumferential direction of the second shaft 32 and can move relatively freely in the axial direction of the second shaft 32. Other shapes will not be described in detail here.

[0090] In this embodiment, the outer peripheral wall of the ratchet structure 52 is provided with a plurality of external teeth 521 for meshing with the transmission mechanism to drive the ratchet structure 52 to rotate. By providing external teeth 521 on the ratchet structure 52, the drive motor can drive the transmission belt, thereby driving the ratchet structure 52 to rotate. The rotation of the ratchet structure 52 can drive the pawl structure 53 to rotate, thereby driving the second shaft 32 to rotate, and thus driving the entire storage module 3 to rotate, thereby realizing the winding of the oil pipe 6.

[0091] In this embodiment, a drive module is also included. The power output end of the drive module is connected to the ratchet structure 52 through a transmission mechanism. The drive module in this embodiment includes a drive motor and a transmission belt (not shown in the figure) and other power output structures, so that the drive motor can drive the ratchet structure 52 to rotate through the transmission belt. The drive module in this embodiment is a conventional structure and will not be described in detail here.

[0092] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
