Description

A transport unloading vehicle for aircraft tire blowouts Technical Field

[0001] This utility model relates to the field of aircraft tire unloading technology, specifically a transport and unloading vehicle for aircraft tire blowouts. Background Technology

[0002] After completing their designated flight missions, aircraft must land. The intense friction between the aircraft tires and the runway surface during landing generates significant smoke. This results in high-speed, high-temperature, and high-wear conditions between the aircraft's rubber tire treads and the concrete runway, leaving visible charred marks on the landing surface. This can lead to tire blowouts, fires, and other flight accidents. Such accidents are unpredictable and cannot be completely prevented. When an aircraft tire blows out, it is crucial to remove the aircraft from the runway immediately to prevent obstructing the landing of subsequent aircraft.

[0003] When disassembling aircraft tires, the weight of the tires themselves causes relative compression between the tires and rims, resulting in tire deformation when the tires are parked. This causes the center of the tire to not coincide with the center of the rim, increasing the difficulty of loosening the lug nuts and making it difficult for workers to remove the tires from the rims. Therefore, a transport and unloading vehicle for aircraft tire blowouts has been proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a transport and unloading vehicle for aircraft tire blowouts, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transport and unloading vehicle for aircraft tire blowouts, comprising a U-shaped base, a gantry frame fixedly connected to the top outer surface of the U-shaped base, an adjusting screw threaded through the top outer surface of the gantry frame, a first crank fixedly connected to the top outer surface of the adjusting screw, a connecting plate rotatably connected to the bottom outer surface of the adjusting screw, two side plates fixedly connected to the top outer surface of the connecting plate, two fixing blocks fixedly connected to the bottom outer surface of the U-shaped base, a positive and negative screw rod rotatably connected between the two fixing blocks, a second crank fixedly connected to the outer surface of the positive and negative screw rod, and two threaded plates threadedly connected to the outer surface of the positive and negative screw rod.

[0006] Furthermore, two support blocks are fixedly connected to the outer surfaces of the two side plates that are far apart from each other. A threaded rod is rotatably connected between the two support blocks. A third crank is fixedly connected to the outer surface of the threaded rod. A threaded block is threadedly connected to the outer surface of the threaded rod. An L-shaped block is fixedly connected to the top outer surface of the threaded block. A limit plate is fixedly connected to the top outer surface of the L-shaped block. A fixing plate is fixedly connected to the top outer surface of the two side plates.

[0007] Furthermore, omnidirectional wheels are installed at the four corners of the bottom of the U-shaped base.

[0008] Furthermore, a sliding rod is fixedly connected between the two fixed blocks, and both threaded plates are movably sleeved on the outer surface of the sliding rod.

[0009] Furthermore, a groove is provided on the outer surface of the side plate, and a slider is fixedly connected to the outer surface of the threaded block, with the slider slidingly connected to the inside of the groove.

[0010] Furthermore, the opposite side of the two side plates is an inclined surface, and an anti-slip pad is fixedly connected to the outer surface of the side plates.

[0011] Furthermore, a fixed post is fixedly connected to the top outer surface of the threaded plate, and a movable post is fixedly connected to the bottom outer surface of the side plate, with the movable post being movably inserted inside the fixed post.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This transport and unloading vehicle for aircraft tire blowouts uses a second crank to rotate the forward and reverse screws, adjusting the position between the two side plates so that the tire can rest on top of the two side plates. The first crank then drives the adjusting screw in conjunction with the connecting plate to adjust the height of the side plates. The side plates support the tire, allowing the concentricity between the tire and the rim to be adjusted. The bolts and bolt holes on the tire are also adjusted simultaneously, making it easier for maintenance personnel to remove the bolts. This greatly improves the efficiency of tire removal and significantly reduces manual labor.

[0014] 2. This transport and unloading vehicle for aircraft tire blowouts uses a third crank to rotate a threaded rod, which in turn moves a threaded block to adjust the position of a limiting plate. This, in conjunction with a fixing plate, clamps and limits the tire. Then, by applying force to the device, the casters move on the ground to transport the tire. This allows for the transport of the tire after it has been removed from the aircraft, saving on the workload and time required for tire transfer. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments

[0021] Referring to Figures 1-4, this utility model provides a technical solution: a transport and unloading vehicle for aircraft tire blowouts, comprising a U-shaped base 1, a gantry frame 2 fixedly connected to the top outer surface of the U-shaped base 1, an adjusting screw 3 threaded through the top outer surface of the gantry frame 2, a first crank 4 fixedly connected to the top outer surface of the adjusting screw 3, a connecting plate 5 rotatably connected to the bottom outer surface of the adjusting screw 3, two side plates 6 fixedly connected to the top outer surface of the connecting plate 5, two fixing blocks fixedly connected to the bottom outer surface of the U-shaped base 1, a positive and negative screw rod 7 rotatably connected between the two fixing blocks, a second crank 9 fixedly connected to the outer surface of the positive and negative screw rod 7, and two threaded plates 8 threadedly connected to the outer surface of the positive and negative screw rod 7. Specifically, by jacking up the aircraft, the device is moved to below the aircraft tire, and the distance between the two side plates 6 is adjusted. First, by rotating the second crank 9, the positive and negative lead screw 7 rotates, which in turn moves the threaded plate 8, causing the two side plates 6 to move. This adjusts the distance between the two side plates 6 so that it corresponds to the bottom of the aircraft tire. The position of the U-shaped base 1 can be moved to fine-tune the distance between the two side plates 6, allowing the tire to rest on top of them. Then, by rotating the first crank 4, the adjusting screw 3 rotates, which in turn moves the connecting plate 5, causing the side plates 6 to move. This adjusts the vertical position of the aircraft tire, aligning the tire with the rim's concentric axis. The screws and bolt holes on the tire are also adjusted simultaneously, facilitating screw removal by maintenance personnel. This significantly improves tire removal efficiency and reduces manual labor.

[0022] In this embodiment, two support blocks are fixedly connected to the outer surfaces of the two side plates 6 that are far apart from each other. A threaded rod 11 is rotatably connected between the two support blocks. A third crank 12 is fixedly connected to the outer surface of the threaded rod 11. A threaded block 13 is threadedly connected to the outer surface of the threaded rod 11. An L-shaped block 14 is fixedly connected to the top outer surface of the threaded block 13. A limiting plate 15 is fixedly connected to the top outer surface of the L-shaped block 14. A fixing plate 10 is fixedly connected to the top outer surface of the two side plates 6. Specifically, during disassembly, the device is moved to the underside of the aircraft tire so that the aircraft tire is in contact with the fixing plate 10. By rotating the third crank 12, the third crank 12 drives the threaded rod 11 to rotate, causing the threaded block 13 to move. The threaded block 13 drives the L-shaped plate to move, adjusting the position of the limiting plate 15 so that the limiting plate 15 limits the other side of the aircraft tire, thereby cooperating with the fixing plate 10 to limit the aircraft tire.

[0023] In this embodiment, omnidirectional wheels are installed at the four corners of the bottom of the U-shaped base 1. Specifically, after the aircraft tire is removed, force is applied to the device to make the omnidirectional wheels move on the ground to transport the tire. This allows the tire to be transported after it has been removed from the aircraft, saving the workload and time of tire transfer.

[0024] In this embodiment, a sliding rod is fixedly connected between the two fixed blocks, and the two threaded plates 8 are movably sleeved on the outer surface of the sliding rod. Specifically, when the positive and negative screws 7 rotate, the threaded plates 8 slide on the outer surface of the sliding rod, so as to prevent the threaded plates 8 from rotating with the positive and negative screws 7.

[0025] In this embodiment, a groove is provided on the outer surface of the side plate 6, and a slider is fixedly connected to the outer surface of the threaded block 13. The slider is slidably connected to the inside of the groove. Specifically, when the threaded rod 11 rotates, it drives the threaded block 13 to move, and the threaded block 13 drives the slider to slide inside the groove, so as to prevent the threaded block 13 from rotating with the rotation of the threaded rod 11.

[0026] In this embodiment, the opposite side of the two side plates 6 is an inclined surface, and an anti-slip pad is fixedly connected to the outer surface of the side plate 6. Specifically, by setting the inclined side plate 6, it is convenient for the aircraft tire to rest on the side plate 6, and by setting the anti-slip pad, the friction of the side plate 6 is increased.

[0027] In this embodiment, a fixed column is fixedly connected to the top outer surface of the threaded plate 8, and a movable column is fixedly connected to the bottom outer surface of the side plate 6. The movable column is movably inserted inside the fixed column. Specifically, when the height of the side plate 6 is adjusted, the movable column slides inside the fixed column, and when the threaded plate 8 moves, the side plate 6 can be moved under the action of the movable column and the fixed column.

[0028] Working Principle: In use, the aircraft is lifted by a jack, and the device is moved to the underside of the aircraft tire. The distance between the two side plates 6 is adjusted. First, the second crank 9 is rotated, which drives the positive and negative screw 7 to rotate. The positive and negative screw 7 drives the threaded plate 8 to move, which in turn moves the two side plates 6, adjusting the distance between them so that it corresponds to the bottom of the aircraft tire. The position of the U-shaped base 1 can be moved to make fine adjustments between the two side plates 6, so that the tire can rest on top of the two side plates 6. Then, the first crank 4 is rotated, which drives the adjusting screw 3 to rotate. The adjusting screw 3 drives the connecting plate 5 to move, which in turn moves the side plates 6, adjusting the vertical position of the aircraft tire. This adjusts the concentricity of the tire and the hub, and the screws and screw holes on the tire are also adjusted simultaneously, making it easier for maintenance personnel to remove the screws. This greatly improves the efficiency of tire removal and significantly reduces manual labor.

[0029] During disassembly, the device is moved under the aircraft tire so that the aircraft tire is in contact with the fixing plate 10. By rotating the third crank 12, the third crank 12 drives the threaded rod 11 to rotate, causing the threaded block 13 to move. The threaded block 13 drives the L-shaped plate to move, adjusting the position of the limiting plate 15 so that the limiting plate 15 limits the other side of the aircraft tire, thereby cooperating with the fixing plate 10 to limit the aircraft tire. Then, by applying force to the device, the casters move on the ground to transport the tire. This allows the tire to be transported after disassembly, saving the workload and time of tire transfer.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
