Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aviation fuel delivery, in particular to a ground fuel delivery system for interacting with an aircraft. BACKGROUND

[0002] In the field of aviation ground support, aircraft interaction fuel delivery equipment is a crucial ground support equipment, and the core component thereof is a fuel delivery vehicle, which is usually equipped with a fuel tank and a fuel pipe connected to the fuel tank for delivering fuel to an aircraft. In order to orderly manage the long fuel pipe and avoid its scattered winding affecting the operation safety and efficiency, the prior art generally provides a storage cylinder on the fuel delivery vehicle for winding and storing the fuel pipe, and the storage cylinder is usually also provided with a one-way locking mechanism.

[0003] The diameter of the cylinder body of the conventional storage cylinder is usually fixed, and this rigid structure design limits the storage capacity and buffering capacity thereof. The one-way locking mechanism design allows an operator to rotate the storage cylinder in one direction to wind and store the fuel pipe, and can prevent reverse rotation through the locking function of the mechanism, thereby maintaining the tension and neatness of the fuel pipe. However, this one-way locking mechanism may expose serious safety hazards in actual application. Specifically, when the operation is ended or an emergency occurs, if the operator directly starts or moves the fuel delivery vehicle without disassembling the fuel pipe connector according to the procedure, the relative displacement between the vehicle and the aircraft will instantly generate a huge pulling force on the fuel pipe. Since the existing one-way locking mechanism cannot be effectively released in an emergency, the storage cylinder is in a locked state and cannot be freely rotated to release the length of the fuel pipe, which causes all the pulling force to be completely borne by the fuel pipe body and its connector. This rigid force transmission mode is extremely easy to cause excessive stretching of the fuel pipe at the connection between the fuel pipe and the connector or at the weak link of the pipe body, which eventually leads to fuel pipe rupture or connector loosening, causing fuel leakage accidents, not only causing economic losses and environmental pollution, but also directly threatening the safe operation of the airport.

[0004] Therefore, the present application provides a ground fuel delivery system for interacting with an aircraft to solve the above technical problems. SUMMARY

Detailed Implementation

[0027] 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.

[0028] 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. 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. 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.

[0029] The embodiment sets the storage module 3, the guiding and tensioning module 4 and the clutch module 5 in cooperation with each other. When the oil pipe 6 is subjected to a great pulling force (i.e. when the airplane and the oil delivery vehicle are relatively displaced), the oil pipe 6 pulls the end of the storage module 3 connected with the guiding and tensioning module 4 to move along the axial direction, so that the clutch module 5 is disengaged from the storage module 3, the locking state of the storage module 3 is released, and the storage module 3 and the clutch module 5 can rotate relatively freely. The original rigid resistance to the oil pipe 6 is changed to flexible release of the oil pipe 6. At the same time, the end of the storage module 3 connected with the guiding and tensioning module 4 moves along the axial direction, so that the diameter of the storage module 3 is reduced, the oil pipe 6 wound on the storage module 3 is more loose, and the oil pipe 6 can be released for a longer distance under the condition of sudden pulling force.

[0030] Therefore, the embodiment can realize the double oil pipe 6 release mechanism of unlocking of the locking state of the oil pipe 6 and cooperation of the diameter contraction of the storage module 3 through the cooperation of the storage module 3, the guiding and tensioning module 4 and the clutch module 5. The pulling force is not completely concentrated on the oil pipe 6 and the joint, the risk of breakage of the oil pipe 6 and loosening of the joint is greatly reduced, and the long-term safety hazard of fuel leakage caused by locking under emergency in the prior art is solved.

[0031] In the embodiment, the oil tank is further arranged on the chassis 1, and the oil inlet end of the oil pipe 6 is communicated with the oil tank.

[0032] In the embodiment, the storage module 3 comprises a first shaft body 31 and a second shaft body 32 arranged coaxially, at least one hinged component 33 and a storage block 34. The storage block 34 and the hinged component 33 are distributed in the circumferential direction of the first shaft body 31 and the second shaft body 32. The hinged component 33 comprises a first hinged rod 331 and a second hinged rod 332 connected in rotation. One end of the first hinged rod 331 is hinged with the first shaft body 31, and the other end is movably connected with the storage block 34. One end of the second hinged rod 332 is movably connected with the second shaft body 32, and the other end is hinged with the storage block 34. In the state that the first shaft body 31 and the second shaft body 32 are away from each other, the storage block 34 approaches along the central axis of the first shaft body 31 and the second shaft body 32 through the hinged component 33. The end of the second shaft body 32 is provided with an engagement connecting pin 321 for engagement with the clutch module 5. The storage module 3 is fixedly connected with the guiding and tensioning module 4 through the end of the second shaft body 32.

[0033] In the embodiment, when the first shaft body 31 and the second shaft body 32 move away from each other, the included angle of the first hinged rod 331 and the second hinged rod 332 will increase, and then the first hinged rod 331 and the second hinged rod 332 extend inward from the end of the first shaft body 31 and the second shaft body 32 away from the central axis, and then drive the receiving block 34 to move in the direction of the central axis of the first shaft body 31 and the second shaft body 32, and then the entire receiving module 3 is reduced in diameter, and the oil pipe 6 wound on the receiving block 34 of the receiving module 3 will become loose due to the reduction in diameter of the receiving module 3, which is beneficial to the rapid release of the oil pipe 6. In the embodiment, the first shaft body 31 is rotatably connected to the chassis 1 by the frame body, and the second shaft body 32 is rotatably connected to the guide and tensioning module 4, so that when the oil pipe 6 is subjected to a pulling force, the oil pipe 6 can pull the second shaft body 32 away from the first shaft body 31 through the guide and tensioning module 4, and at the same time, the engagement state of the second shaft body 32 and the clutch module 5 is synchronously released, so that the rotation of the receiving module 3 to release the oil pipe 6 is no longer limited by the clutch module 5.

[0034] In the embodiment, the receiving module 3 further comprises a fixed mounting block 36 and a movable mounting block 35. The first hinged rod 331 is hinged to the first shaft body 31 through the fixed mounting block 36, and the second hinged rod 332 is hinged to the receiving block 34 through the fixed mounting block 36. The movable mounting block 35 is provided with a sliding groove 351 and a sliding pin 352 slidingly arranged in the sliding groove 351, the first hinged rod 331 is movably connected to the first shaft body 31 through the sliding pin 352, and the second hinged rod 332 is movably connected to the receiving block 34 through the sliding pin 352. In the embodiment, the fixed mounting block 36 and the movable mounting block 35 are arranged, and the sliding groove 351 is arranged in the movable mounting block 35, the sliding groove 351 is long strip-shaped, and the length direction of the sliding groove 351 is parallel to the axial direction of the first shaft body 31 and the second shaft body 32, so that the second shaft body 32 can move smoothly along the axial direction.

[0035] In the embodiment, the receiving block 34 comprises a fixedly connected connecting plate 341 and a receiving plate 342, and the connecting plate 341 and the receiving plate 342 are distributed inside and outside along the radial direction of the first shaft body 31 and the second shaft body 32. The first hinged rod 331 is movably connected to the connecting plate 341 of the receiving block 34. The second articulated rod 332 is hinged with the connecting plate 341 of the receiving block 34, and in the embodiment, a transverse and longitudinal side plate in the shape of a sector of a circle is arranged between the receiving plate 342 and the connecting plate 341, so that the receiving plate 342 and the connecting plate 341 can be connected into one body through the side plate in the shape of a sector of a circle. The arrangement of the side plate in the shape of a sector of a circle can increase the receiving diameter of the whole receiving module 3, ensure that the receiving length of the oil pipe 6 is sufficient, and at the same time, the same receiving angular velocity can ensure a higher receiving linear velocity, thereby improving the receiving efficiency of the oil pipe 6.

[0036] In the embodiment, the guiding and tensioning module 4 comprises a first mounting frame 41 for mounting on the chassis 1, and a second mounting frame 42 suspended through the first mounting frame 41. The first mounting frame 41 is provided with a first fixed guide wheel 412. The second mounting frame 42 is provided with three second fixed guide wheels 421. The guiding and tensioning module 4 further comprises a tensioning assembly 43 rotationally connected with the receiving module 3 and used for pulling the oil pipe 6 radially to move the oil pipe 6, and the tensioning assembly 43 comprises a movable guide wheel 432. The oil pipe 6 is arranged in a wave-shaped staggered manner on the second fixed guide wheels 421, the first fixed guide wheel 412 and the movable guide wheel 432, and 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.

[0037] In the embodiment, the guiding and tensioning module 4 can play a guiding role for the receiving of the oil pipe 6, and when the oil pipe 6 is subjected to a relatively large pulling force, the oil pipe 6 can pull the tensioning assembly 43 to move through the movable guide wheel 432, thereby driving the second shaft body 32 to move away from the first shaft body 31.

[0038] In the embodiment, the second fixed guide wheel 421 is provided with three, and the oil pipe 6 is arranged in a W-shaped manner in the whole guiding and tensioning module 4. In some embodiments, the first fixed guide wheel 412 can be removed, and only two second fixed guide wheels 421 are arranged, so that the oil pipe 6 is arranged in a V-shaped manner. However, only two second fixed guide wheels 421 are arranged, which is easy to cause mis-triggering. Arranging too many first fixed guide wheels 412 and second fixed guide wheels 421 is also easy to cause the oil pipe 6 to be difficult to pull the tensioning assembly 43, so that the second shaft body 32 is difficult to trigger to move away from the first shaft body 31, thereby causing the receiving module 3 to be difficult to shrink, and the meshing state between the clutching module 5 and the receiving module 3 to be difficult to release.

[0039] In the embodiment, the tensioning assembly 43 further comprises a mounting seat 431 and a guide seat 434, and a guide rod 433, a connecting barrel 435 and a reset spring 436. The mounting seat 431 and the connecting cylinder 435 are fixed at two ends of the guide rod 433, and the guide rod 433 is in sliding connection with the guide seat 434; The tensioning assembly 43 is in rotary connection with the storage module 3 through the connecting cylinder 435; The movable guide wheel 432 is arranged on the mounting seat 431; The guide seat 434 is fixed on the first mounting frame 41; One end of the reset spring 436 is connected to the mounting seat 431, and the other end is connected to the guide seat 434. Through the arrangement of the guide seat 434, the mounting seat 431, the guide rod 433 and the like, the second shaft body 32 can be limited in the pulling direction. The reset spring 436 arranged can make the storage module 3 reengage with the clutch module 5 after the pulling force of the oil pipe 6 is reduced, and the guide tensioning module 4 reconverts to the state of being able to rotate only in one direction to store the oil pipe 6.

[0040] In the embodiment, the side surface of the first mounting frame 41 is provided with a cantilever frame 411, the first fixed guide wheel 412 is arranged on the cantilever frame 411, and the second mounting frame 42 is arranged in suspension through the cantilever frame 411.

[0041] In the embodiment, the clutch module 5 includes a seat body 51 arranged on the chassis 1, a ratchet structure 52 arranged on the seat body 51, and a pawl structure 53 arranged in the ratchet structure 52. The ratchet structure 52 is provided with a ratchet tooth groove 522 for cooperation with the pawl structure 53, the outer periphery of the pawl structure 53 is provided with a plurality of pawl main bodies 532 cooperating with the ratchet tooth groove 522, and the pawl structure 53 is provided with an engagement connection groove 531 for engagement with the end of the guide tensioning module 4. The ratchet structure 52 and the pawl structure 53 are one-way free rotation through the cooperation of the ratchet groove 522 and the pawl body 532. The ratchet groove 522 and the pawl body 532 are set so that after the clutch assembly is sleeved on the second shaft body 32 of the storage module 3, it is only one-way limited. For example, after the pawl structure 53 is sleeved on the second shaft body 32 through the engagement connection groove 531 and engages with the engagement 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 body 32 to rotate clockwise. At this time, the storage module 3 is in the oil pipe 6 storage state. When the driving 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 have a tendency to rotate counterclockwise through the second shaft body 32, and 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 large pulling force, thereby causing the engagement state of the second shaft body 32 and the pawl body 532 to be released.

[0042] In the embodiment, the engagement connection pin 321 provided on the second shaft body 32 and the engagement connection groove 531 of the pawl structure 53 can be respectively provided as splines and splines or other mutually cooperating mechanical structures, as long as they can be mutually limited in the circumferential direction of the second shaft body 32 and can be relatively freely moved in the axial direction of the second shaft body 32. Other shapes are not described in detail here.

[0043] In the embodiment, the outer peripheral wall of the ratchet structure 52 is provided with a plurality of external teeth 521 for engaging with the transmission mechanism to drive the ratchet structure 52 to rotate. By providing the external teeth 521 on the ratchet structure 52, the driving motor can drive the transmission belt and in turn drive 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 body 32 to rotate, and in turn driving the entire storage module 3 to rotate, thereby realizing the winding of the oil pipe 6.

[0044] In the embodiment, a driving module is further included, and a power output end of the driving module is in transmission connection with the ratchet structure 52 through a transmission mechanism. The driving module in the embodiment includes a driving motor and a transmission belt (not shown in the figure) and other power output structures, so that the driving motor can drive the ratchet structure 52 to rotate through the transmission belt. The driving module in the embodiment is a conventional structure, and will not be described in detail here.

[0045] It is understood that the above embodiments are only exemplary for illustrating the principles of the present application, and the present application is not limited thereto. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of the present application, and these modifications and improvements are also considered as the protection scope of the present application.
