[0002] The main function of the aircraft auxiliary fuel tank hanging beam is to suspend and fix the auxiliary fuel tank to ensure its stability and safety during flight. The main function of the auxiliary fuel tank is to increase the flight range of the aircraft. During long-range combat or long-distance flight, the auxiliary fuel tank can provide additional fuel reserves for the aircraft to extend the flight range or loiter time of the aircraft. At the same time, by reasonably arranging the hanging beam and mounting the auxiliary fuel tank, the center of gravity position of the aircraft can be adjusted to keep it in the best flight state.
[0003] However, to ensure the maintenance and disassembly of the aircraft auxiliary fuel tank hanging beam, multiple people need to cooperate at the bottom of the aircraft, which not only consumes a large amount of energy and physical strength of too many people, but also the installation heights of the aircraft hanging beams are different, resulting in difficulties in setting up personnel workstations and very inconvenient disassembly and lifting, seriously affecting the operation efficiency.
[0004] Therefore, those skilled in the art have proposed a lifting bracket for the disassembly and assembly of an aircraft auxiliary fuel tank hanging beam to solve the problems raised in the background technique. Content of the Utility Model

[0028] Furthermore, the side wall of the connecting seat 7 is fixedly connected to the side wall of the base 1, and the push rod 6 is rotatably connected to the inner wall of the connecting seat 7.
[0029] Furthermore, a plurality of balls 14 are provided at the bottom of the connecting plate 8. The plurality of balls 14 are rotatably connected to the bottom of the connecting plate 8, and the connecting plate 8 is rotatably connected to the top of the base 1 through the balls 14.
[0030] Furthermore, a protective box 9 is provided at the top of the connecting plate 8. A collecting rack 10 is arranged inside the protective box 9. The protective box 9 is fixedly connected to the top of the connecting plate 8, and the collecting rack 10 is slidably connected to the inside of the protective box 9.
[0031] Furthermore, a spring 12 is arranged inside the protective box 9. The spring 12 is fixedly connected to the bottom of the protective box 9. An air groove 11 is formed at the top of the protective box 9, and a movable plate 13 is clamped to the top of the protective box 9.
[0032] Furthermore, the design of the present invention is applied in that, before disassembly, a risk assessment is carried out to identify possible risk factors, the required tools and equipment are inspected and prepared to ensure that they are in good condition. First, disconnect the connection between the auxiliary fuel tank and the aircraft electrical system and fuel system to ensure that there will be no current or fuel leakage during the disassembly process. After removing the fixing bolts, use a hoisting device to smoothly lift the auxiliary fuel tank from the hanging beam. After the auxiliary fuel tank is removed, carefully check whether the hanging beam and its connecting parts are damaged or worn. If any problems are found, they need to be repaired or replaced in time.
[0033] As can be seen from the above, by rotating the push rod 6 to disengage the side wall of the push rod 6 from the inside of the connecting seat 7. It should be noted that there are two connecting seats 7, and the two connecting seats 7 are located on the side wall of the base 1 and the side wall of the support seat 4. The connecting seat 7 on the side wall of the support seat 4 has a clamping effect. By pushing the push rod 6, the push rod 6 drives the base 1 to move. Using the universal wheels 2 at the bottom of the base 1, the base 1 is moved to the bottom of the aircraft. It should be noted that when the base 1 moves, the movement of the base 1 is made more flexible through the position sensor 504. By pasting an induction sticker at the hanging beam at the bottom of the aircraft, and by pushing the base 1 to move, when the base 1 drives the position sensor 504 to move to the hanging beam, the position sensor 504 will emit a warning sound. It should be noted that to ensure the accuracy at the hanging beam, there are warning sounds of different distances between the position sensor 504 and the sticker, which are divided into slow and rapid differences. When the base 1 moves to the appropriate position, by the rotation of the motor 502, the motor 502 drives the lead screw 506 to rotate. It should be noted that the power source used by the motor 502 is the power source in the storage battery 3, and the storage battery 3 is placed on the top of the base 1. By the rotation of the lead screw 506, the lead screw 506 drives the arc-shaped rod 507 to move relatively. By the relative movement of the arc-shaped rod 507, the arc-shaped rod 507 pushes the baffle 503 and the support frame 501 to move upward. When the baffle 503 touches the hanging beam, technicians can perform maintenance work on the hanging beam and the auxiliary fuel tank. During the work, by pulling the movable plate 13, the movable plate 13 is disengaged from the top of the collection rack 10. By pulling the collection rack 10 upward, the tools in the collection rack 10 are convenient for technicians to use. By rotating the movable plate 13 in the reverse direction, the movable plate 13 is clamped on the top of the collection rack 10 to achieve the fixing effect on the collection rack 10. When the maintenance is completed, by rotating the movable plate 13, the gas in the protection box 9 is discharged under the action of the collection rack 10, and the collection rack 10 enters the inside of the protection box 9. To ensure that the collection rack 10 is easier to pull, an isolation treatment is carried out through the spring 12. At the same time, when it is necessary to adjust the protection box 9, by pushing the protection box 9, the balls 14 at the bottom of the connecting plate 8 rotate on the top of the base 1, and the protection box 9 moves. It should be noted that the collection rack 10 needs to be pushed into the protection box 9 before the protection box 9 can be pushed to the other side of the support seat 4.
[0034] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a spring 12 is arranged in the protection box 9, the spring 12 is fixedly connected to the bottom of the protection box 9, an air groove 11 is opened at the top of the protection box 9, and a movable plate 13 is clamped at the top of the protection box 9.
[0035] As can be seen from the above, when the tools needed by technicians are out of reach, by pulling the movable plate 13, the movable plate 13 is opened, by pulling the collection rack 10 upward, the bottom of the collection rack 10 is moved to the top of the protection box 9, and by pushing the movable plate 13, the bottom of the movable plate 13 is clamped to the top of the collection rack 10. At the same time, the pressure inside the collection rack 10 will push the collection rack 10 downward. Through the cooperation between the collection rack 10 and the movable plate 13, the whole collection rack 10 is separated from the inside of the protection box 9, thus facilitating the technicians to use the tools.
[0036] The embodiments of the present invention are given for the purposes of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
