Description

Technical Field

[0001] This utility model belongs to the field of aviation airport refueling technology, and in particular relates to a fuel nozzle gripping component, which can be applied to aviation fuel refueling assistance systems. Background Technology

[0002] Aviation fuel supply is a crucial part of the civil aviation system, providing strong support for the development of my country's civil aviation industry. Currently, most aircraft refueling is done manually. The process involves first driving the fuel delivery truck to the side of the wing below the refueling port. The refueling hose is then manually pulled to the bottom of the refueling port. The operator then climbs the fuel hose ladder, which is then raised closer to the aircraft's refueling port. The refueling operator aligns the fuel nozzle with the aircraft's refueling port, connecting the nozzle's outlet to the refueling port before proceeding with the refueling operation. During this process, refueling operators often need to continuously pull and lift the fuel hoses and nozzles before finally inserting the nozzles into the refueling port to begin refueling, which greatly depletes their physical strength. Furthermore, surveys show that an average aircraft refueling operator performs about 18 refueling missions per day, reaching up to 20 during peak periods. For large aircraft, each refueling operation requires lifting two fuel hoses, each carrying a load of approximately 25 kg, further increasing the physical exertion on the operators. In addition, the working environment for refueling operators is primarily open-air, with the tarmac exposed and offering no shelter, meaning they often work in high temperatures. During busy flight periods or special support times, they may have to work continuously for over ten hours, making the workload extremely demanding. Therefore, this high-intensity work causes a sharp decline in the physical strength of refueling operators, leading to decreased work efficiency and potentially resulting in delays in refueling operations.

[0003] As mentioned above, the high-intensity work in the existing technology can cause a sharp decline in the physical strength of refueling personnel, resulting in a decrease in their work efficiency. Consequently, in the subsequent refueling work, there may be insufficient time to refuel the aircraft, thus causing flight delays. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, high-intensity work can cause a sharp decline in the physical strength of refueling workers, resulting in a decrease in their work efficiency and, consequently, a delay in refueling the aircraft, thus causing flight delays.

[0005] In view of this, the present invention provides a fuel nozzle gripping component. By installing the gripping component on the lifting frame of the pipeline refueling truck, the fuel nozzle can be gripped during refueling, and then the lifting frame can be used to lift the fuel nozzle to the aircraft refueling port. This eliminates the need for the refueling operator to grab and drag the fuel nozzle to the aircraft refueling port, reducing the workload of the refueling operator, improving the work efficiency of the refueling operator, and avoiding the problem of not being able to refuel the aircraft in time.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: the oil gun gripping component includes a base, a clamping component and a driving component mounted on the base; wherein, the base has a passage opening at one end in the length direction.

[0007] The clamping assembly includes a first clamping member and a second clamping member that are spaced apart on the base along the width direction of the base. One end of the first clamping member and the second clamping member are movably mounted on the base, and the other end extends toward the opening end of the through opening. A clamping space is formed between the first clamping member and the second clamping member. Furthermore, when viewed along the thickness direction of the base, the projection of the clamping space is located within the through opening.

[0008] The drive assembly includes a transmission component and a drive component mounted on a base. The transmission component includes a first transmission member and a second transmission member. One end of the first transmission member is connected to the drive end of the drive component, and the other end is connected to one end of the first clamping member. One end of the second transmission member is connected to the drive end of the drive component, and the other end is connected to one end of the second clamping member. Furthermore, the drive end of the drive component can drive the first transmission member and the second transmission member, and in conjunction with the first clamping member and the second clamping member, swing along the width direction of the base.

[0009] The above technical solution involves installing the fuel nozzle gripping assembly on the lifting frame of the pipeline refueling truck. When an aircraft is parked on the tarmac and refueling is required, the first and second clamping components are opened, and the fuel nozzle is inserted into the clamping space through the opening. The first and second clamping components then hold the fuel nozzle in place. When the pipeline truck lifting frame rises, it moves the fuel nozzle gripping assembly upwards, thus moving the fuel nozzle upwards as well. This eliminates the need for manual lifting onto the lifting platform, offering advantages such as ease of use and reduced physical exertion for refueling personnel. It avoids the problem of reduced work efficiency caused by prolonged dragging of fuel lines and lifting of fuel nozzles, which leads to decreased physical strength. Furthermore, it solves the problem of flight delays in emergency situations, such as when an aircraft is on an emergency rescue mission or when the next flight has a short layover.

[0010] Furthermore, to ensure safety during refueling, one embodiment of the fuel nozzle gripping assembly includes a driving component comprising a driving cylinder mounted on a base and whose driving end can translate along the length of the base, a first pneumatic control switch, and a second pneumatic control switch fixedly mounted on the side wall through the opening.

[0011] The first pneumatic control switch is connected to the outlet of the driving cylinder through the first gas pipeline and is used to open or close the outlet of the driving cylinder. The second pneumatic control switch is connected to the inlet of the driving cylinder through the second gas pipeline and is used to open or close the inlet of the driving cylinder.

[0012] One end of the first transmission component is rotatably connected to the driving end of the driving cylinder, and the other end is drive-connected to one end of the first clamping component. One end of the second transmission component is drive-connected to the driving end of the driving cylinder, and the other end is drive-connected to one end of the second clamping component.

[0013] To further improve the convenience and accuracy of aircraft refueling, this utility model also provides an aviation fuel refueling assistance system, including a base, a lifting component installed on the base, a position adjustment component installed on the end of the lifting component away from the base, and the aforementioned fuel nozzle gripping component.

[0014] The lifting assembly includes a lifting component with one end fixedly mounted on the base and the other end extending vertically upward, and a power component mounted on the base for driving the lifting component to rise vertically.

[0015] The position adjustment assembly includes a connecting part and an adjustment part that can swing relative to the connecting part. One end of the connecting part is rotatably connected to the other end of the lifting part and can rotate about a vertical axis. One end of the adjustment part is rotatably connected to the other end of the connecting part about a horizontal axis, and the other end extends away from the lifting part. The base of the oil gun gripping assembly is fixedly disposed on the top surface of the fixed seat at the other end away from the opening in the length direction and is fixedly installed on the other end of the lifting part through the fixed seat.

[0016] By adopting the above technical solution, the fuel nozzle gripping component is installed at the end of the lifting component away from the base. When refueling the aircraft through this aviation fuel refueling assist system, the refueling operator holds the refueling nozzle with the fuel nozzle gripping component and then adjusts the height of the refueling nozzle by using the lifting component. After the height adjustment is completed, the position of the fuel nozzle can be adjusted by rotating the connecting component around the axis of the lifting component and by swinging the adjusting component around the vertical direction. There is no need to release the refueling nozzle, and the stability is good.

[0017] Furthermore, in order to accurately adjust the position of the fuel nozzle so that it can be aligned with the aircraft refueling port, one embodiment of the aviation fuel refueling assist system also includes a protective component. The protective component includes a protective frame and a support seat disposed within the protective frame. The base is slidably disposed on the support seat along the width direction of the protective component, and the support seat is slidably disposed on the bottom wall of the protective frame along the length direction of the protective component.

[0028] On average, each aircraft refueling operator performs approximately 18 refueling missions per day, with peak periods reaching 20. For large aircraft, each refueling operation requires lifting two fuel hoses, each carrying a load of about 25 kg, resulting in significant physical exertion for the operators. Furthermore, the working environment for refueling operators is primarily open-air, with the tarmac offering no shelter, often requiring them to work in high temperatures. During busy flight periods or special support times, they may have to work continuously for over ten hours, making the workload extremely demanding. Therefore, this high-intensity work causes a sharp decline in the operators' physical strength, leading to decreased work efficiency and potentially causing delays in refueling subsequent aircraft.

[0029] To address the aforementioned issues, this utility model discloses a fuel nozzle gripping assembly. When refueling an aircraft, the first and second clamping components are opened, and the fuel nozzle is inserted into the clamping space through the opening. The first and second clamping components then hold the fuel nozzle in place. When the pipeline vehicle's lifting platform rises, the fuel nozzle gripping assembly moves upward, carrying the fuel nozzle with it. This eliminates the need for manual handling and allows for easy use while saving refueling personnel's energy. It avoids the problem of reduced work efficiency caused by prolonged dragging of fuel lines and lifting of fuel nozzles, thus resolving the issue of flight delays in emergency situations, such as when the aircraft is on an emergency rescue mission or when the next flight has a short layover.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, Embodiment 1 of this utility model discloses an oil gun gripping assembly 1, including a base 10, a clamping assembly 11 mounted on the base 10, and a driving assembly 12; wherein, the base 10 has a passage opening 100 at one end in the length direction.

[0033] The clamping assembly 11 includes a first clamping member 110 and a second clamping member 120 spaced apart on the base 10 along the width direction of the base 10. One end of the first clamping member 110 and the second clamping member 120 are movably mounted on the base 10, and the other end extends toward the opening end of the through opening 100. A clamping space 130 is formed between the first clamping member 110 and the second clamping member 120. When viewed along the thickness direction of the base 10, the projection of the clamping space 130 is located within the through opening 100.

[0034] The drive assembly 12 includes a transmission component and a drive component 140 mounted on the base 10. The transmission component includes a first transmission member and a second transmission member. One end of the first transmission member is connected to the drive end of the drive component 140, and the other end is connected to one end of the first clamping member 110. One end of the second transmission member is connected to the drive end of the drive component 140, and the other end is connected to one end of the second clamping member 120. The drive end of the drive component 140 can drive the first transmission member and the second transmission member, and link the first clamping member 110 and the second clamping member 120 to swing along the width direction of the base 10.

[0035] The fuel nozzle gripping assembly 1 is installed on the lifting frame of the pipeline refueling truck. When the aircraft is parked on the tarmac and needs to be refueled, the first clamping component 110 and the second clamping component 120 are opened, and the fuel nozzle is inserted into the clamping space 130 through the opening end of the opening 100. The first clamping component 110 and the second clamping component 120 then clamp the fuel nozzle. When the pipeline truck lifting frame rises, it can drive the fuel nozzle gripping assembly 1 to move upward and drive the fuel nozzle upward. There is no need for manual lifting to the lifting platform. It has the advantages of convenient use and saving the refueling operator's physical strength. It avoids the problem of reduced work efficiency caused by the refueling operator's physical strength due to prolonged dragging of fuel lines and lifting of fuel nozzles. It also solves the problem of flight delays in some emergency situations, such as when the aircraft has an emergency rescue mission or the next flight has a short downtime.

[0036] Furthermore, by setting the base 10, when the first clamping component 110 and the second clamping component 120 are opened, the base 10 also provides support for the tightening handle on the fuel nozzle, preventing the risk of the fuel nozzle suddenly falling.

[0037] Furthermore, the structure and configuration of the following driver component 12 will be further explained.

[0038] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the drive component 140 includes a drive cylinder 180 mounted on the base 10 and whose drive end can translate along the length direction of the base 10, a first pneumatic switch 150, and a second pneumatic switch 160 fixedly mounted on the side wall of the opening 100.

[0039] Specifically, the first pneumatic switch 150 is connected to the outlet of the drive cylinder 180 through the first gas pipeline and is used to open or close the outlet of the drive cylinder 180. The second pneumatic switch 160 is connected to the inlet of the drive cylinder 180 through the second gas pipeline and is used to open or close the inlet of the drive cylinder 180.

[0040] More specifically, one end of the first transmission component is rotatably connected to the drive end of the drive cylinder 180, and the other end is drive-connected to one end of the first clamping component 110. One end of the second transmission component is drive-connected to the drive end of the drive cylinder 180, and the other end is drive-connected to one end of the second clamping component 120.

[0041] Specifically, by configuring the drive component 140 as a drive cylinder 180, the opening and closing of the air outlet of the drive cylinder 180 is controlled by the first pneumatic switch 150, and the opening and closing of the air inlet of the drive cylinder 180 is controlled by the second pneumatic switch 160. When the drive cylinder 180 needs to drive the first clamping component 110 and the second clamping component 120 to open or clamp, it is only necessary to open or close the first cylinder or the second cylinder to achieve the clamping or releasing of the refueling nozzle, which has the advantage of convenient operation. Furthermore, since the transmission process of this fuel nozzle gripping assembly 1 is all pneumatic, there is no source of ignition or electricity, which avoids the ignition of aviation fuel due to accidental fire, thus improving safety.

[0042] It should be understood that both the first pneumatic switch 150 and the second pneumatic switch 160 can be roller lever mechanical valves, pressure relief valves, etc., and this embodiment does not limit them.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, the structure and arrangement of the clamping component 11 will be further explained below.

[0044] In one feasible embodiment, the first clamping component 110 includes a first clamping arm and a first rotating shaft, and the second clamping component 120 includes a second clamping arm and a second rotating shaft. The first rotating shaft and the second rotating shaft are spaced apart along the width direction of the base 10 and are both fixedly connected to the base 10. One end of the first clamping arm is rotatably connected to the first rotating shaft, and the other end extends toward the opening end of the opening 100. One end of the second clamping arm is rotatably connected to the second rotating shaft, and the other end extends toward the opening end of the opening 100. The clamping space 130 is located between the first clamping arm and the second clamping arm.

[0045] The first transmission component is configured as a first transmission rod, and the second transmission component is configured as a second transmission rod. One end of the first transmission rod is rotatably connected to the driving end of the driving cylinder 180, and the other end is rotatably connected to one end of the first clamping arm. One end of the second transmission rod is rotatably connected to one end of the driving cylinder 180, and the other end is rotatably connected to one end of the second clamping arm.

[0046] Specifically, in this embodiment, when the oil gun gripping assembly 1 is used to grip the end of the oil gun, the first pneumatic switch 150 is turned on, thereby causing the drive cylinder 180 to release air. The drive end retracts, thereby pulling the first clamping arm and the second clamping arm away from each other through the first transmission rod and the second transmission rod, opening the clamping space 130. Then, the oil gun is pushed into the clamping space 130. Further, after the oil gun is pushed into the clamping space 130, the side wall of the oil gun presses against the second pneumatic switch 160, thereby causing the drive cylinder 180 to take in air. The drive end extends, thereby pulling the first clamping arm and the second clamping arm closer together to clamp the oil gun through the first transmission rod and the second transmission rod. This has the advantage of convenient operation.

[0047] In another possible implementation, the first clamping component 110 includes a first swing arm, a first rotating shaft, and a first rotating gear, and the second clamping component 120 includes a second swing arm, a second rotating shaft, and a second rotating gear. The first rotating shaft and the second rotating shaft are spaced apart along the width direction of the base 10 and are both rotatably connected to the base 10. One end of the first swing arm is fixedly connected to the first rotating shaft, and the other end extends toward the opening end of the opening 100. The first rotating gear is sleeved on the first rotating shaft and fixedly connected to the first rotating shaft. One end of the second swing arm is fixedly connected to the second rotating shaft, and the other end extends toward the opening end of the opening 100. The second rotating gear is sleeved on the second rotating shaft and fixedly connected to the second rotating shaft.

[0048] The first transmission component is configured as a first rack, and the second transmission component is configured as a second rack. One end of the first rack is fixedly connected to the driving end of the driving cylinder 180, and the other end meshes with the first rotating gear. One end of the second rack is fixedly connected to one end of the driving cylinder 180, and the other end meshes with the second rotating gear.

[0049] Specifically, in this embodiment, when the oil gun gripping assembly 1 is used to grip the end of the oil gun, the oil gun is placed in the clamping space 130 and the first pneumatic switch 150 is turned on, thereby causing the drive cylinder 180 to release air. The drive end retracts, thereby linking the first rack and the second rack to move in a direction away from the opening end of the opening 100, thereby linking the first rotating gear and the second rotating gear to rotate, driving the first rotating shaft and the second rotating shaft to rotate, and linking the first swing arm and the second swing arm to move closer to each other to clamp the oil gun, and then pushing the oil gun into the clamping space 130. Furthermore, when the fuel nozzle is released, the refueling operator squeezes the second pneumatic switch 160 through the side wall of the fuel nozzle, thereby causing the drive cylinder 180 to take in air. The drive end extends and moves in the direction of the first rack and the second rack through the linkage towards the opening end of the opening 100. This, in turn, causes the first rotating gear and the second rotating gear to rotate, driving the first rotating shaft and the second rotating shaft to rotate and causing the first swing arm and the second swing arm to move away from each other to release the fuel nozzle. Then the fuel nozzle is taken out from the clamping space 130, which further improves the convenience of the fuel nozzle gripping component 1.

[0050] Optionally, such as Figure 2 As shown, the clamping assembly 11 also includes a snap fastener 170, which can be clamped in the clamping space 130 by the first clamping component 110 and the second clamping component 120. The snap fastener 170 is sleeved on the outer periphery of the nozzle head of the oil gun. The first pneumatic switch 150 is disposed at the other end of the base 10 in the length direction and extends at least partially into the through opening 100. When the snap fastener 170 is clamped in the clamping space 130, the edge of the snap fastener 170 abuts against the portion of the first pneumatic switch 150 that extends into the through opening 100. Furthermore, the first clamping component 110 and the second clamping component 120 are evenly distributed with ball bearings on the sidewalls facing the clamping space 130.

[0051] Specifically, by setting the snap-fit ​​170, it is convenient to limit the oil gun's position, and it also allows the first clamping component 110 and the second clamping component 120 to be placed without damaging the side wall of the oil gun due to excessive clamping force. The first clamping component 110 and the second clamping component 120 are evenly provided with ball bearings on the side wall facing the clamping space 130, which allows the snap-fit ​​to be finely adjusted in position.

[0052] Example 2

[0053] like Figure 3 As shown, Embodiment 2 of this utility model discloses an aviation fuel refueling assistance system 2, including a base 23, a lifting component 20 installed on the base 23, a position adjustment component 21 installed on the end of the lifting component 20 away from the base 23, and the fuel gun gripping component 1 in Embodiment 1.

[0054] Specifically, the lifting assembly 20 includes a lifting component 200 with one end fixedly mounted on the base 23 and the other end extending vertically upward, and a power component mounted on the base 23 for driving the lifting component 200 to rise vertically; the position adjustment assembly 21 includes a connecting component 210 and an adjusting component 220 that can swing relative to the connecting component 210, wherein one end of the connecting component 210 is rotatably connected to the other end of the lifting component 200 and can rotate around the vertical axis, one end of the adjusting component 220 is rotatably connected to the other end of the connecting component 210 around the horizontal axis, and the other end extends in a direction away from the lifting component 200; the base 10 of the oil gun gripping assembly 1 is fixedly disposed on the top surface of the fixed seat 13 at the other end away from the opening 100 in the length direction and is fixedly mounted on the other end of the lifting component 200 through the fixed seat 13.

[0055] Specifically, the fuel nozzle gripping assembly 1 is installed at the end of the lifting assembly 20 away from the base 23. When refueling the aircraft through the aviation fuel refueling assist system 2, the refueling operator holds the refueling nozzle with the fuel nozzle gripping assembly 1 and then adjusts the height of the refueling nozzle with the lifting assembly 20. After the height adjustment is completed, the position of the fuel nozzle in the horizontal direction is changed by rotating the connecting component 210 around the axis of the lifting assembly 200, and the vertical position of the fuel nozzle can be adjusted by swinging the adjusting component 220 in the vertical direction, so that the fuel nozzle is aligned with the refueling port. There is no need to manually remove the fuel nozzle held on the fuel nozzle gripping assembly 1, which has the advantage of convenient operation.

[0056] Furthermore, in one feasible implementation, the aviation fuel refueling assist system 2 further includes a protective component, which includes a protective frame 22 and a support seat 25 disposed within the protective frame 22; wherein, the base 23 is slidably disposed on the support seat 25 along the width direction of the protective component, and the support seat 25 is slidably disposed on the bottom wall of the protective frame 22 along the length direction of the protective component.

[0057] Specifically, by setting the base 23 to slide along the width direction of the protective component on the support 25, and the support 25 to slide along the length direction of the protective component on the bottom wall of the protective frame 22, the position of the lifting component 200 can be adjusted in advance, so that the oil gun held on the oil gun gripping component 1 is positioned vertically below the aircraft refueling port. The position of the oil gun is pre-positioned, so that after the oil gun is lifted by the lifting component 200, it can be closer to the refueling port, making it easier for the staff to connect the oil gun to the refueling port.

[0058] Furthermore, the structure and arrangement of the lifting assembly 20 will be explained in more detail below.

[0059] In one feasible implementation, the lifting component 200 is a lifting rod, and the power component is a foot pedal drive switch. One end of the lifting rod is fixedly installed on the base 23, and the other end extends upward in the vertical direction. The foot pedal drive switch is fixedly installed on the base 23 and is connected to the lifting rod in a transmission manner. When the foot pedal drive switch is stepped on, the lifting rod can rise in the vertical direction.

[0060] Specifically, the power unit is configured with a foot-operated switch. Operators control the height of the lifting boom as they raise the fuel nozzle, preventing the nozzle from being too high and failing to connect with the refueling port. It's important to understand that the lifting boom should be hydraulic or pneumatic to ensure the aircraft is refueling without any source of ignition or power, guaranteeing safety.

[0061] Furthermore, the structure and configuration of the position adjustment component 21 will be explained in more detail below.

[0062] In one feasible embodiment, the connecting component 210 is a rotating seat, and the adjusting component 220 includes a rotating shaft and a rocker arm; wherein, the rotating seat is rotatably connected to the other end of the lifting rod and can rotate about the vertical axis, the rotating shaft is fixedly installed on one end of the rocker arm and is rotatably mounted on the rotating seat about the horizontal axis, and the other end of the rocker arm extends in a direction away from the rotating seat and is fixedly connected to the fixed seat 13.

[0063] Specifically, when the fuel nozzle is lifted by the lifting component 200 to the area below the refueling port and aligned with the refueling port, the position of the fuel nozzle in the horizontal plane can be changed by rotating the rotating base around the vertical axis, and the position of the fuel nozzle in the vertical direction can be changed by rotating the swing arm around the horizontal axis, thus facilitating the docking of the fuel nozzle with the aircraft's refueling port.

[0064] Furthermore, in the embodiment disclosed in this example, the aviation fuel refueling assist system 2 further includes a fuel injection pipe 24 and a fuel pipe passage through the side wall of the protective frame 22; wherein, one end of the fuel injection pipe 24 is connected to the fuel storage chamber, and the other end passes through the fuel pipe passage through the side wall of the protective frame 22 and is connected to a fuel gun; and, a snap-fit ​​part is provided on the inner side of the fuel pipe passage, and a snap-fit ​​part adapted to the snap-fit ​​part is provided on the fuel gun.

[0065] Specifically, by setting an oil pipe access port, it is easy for the oil injection pipe 24 to enter the protective frame 22. A snap-fit ​​part is provided on the inside of the oil pipe access port, and the oil gun is provided with a snap-fit ​​part that matches the snap-fit ​​part, so that the oil gun can be placed when it is not in use.

[0066] It should be understood that the snap-fit ​​part can be a snap-fit ​​socket, a snap-holding socket, etc., and the snapped part can be a snap-fit ​​block, a connecting block, etc., which are not limited in this embodiment.
