[0002] Aviation tires are usually installed on the landing gear of an aircraft. During takeoff and landing of the aircraft, the tires need to roll on the ground through friction. To extend the service life of the tires, slow down tire aging, and avoid ultraviolet erosion, it is necessary to spray some maintenance products.

[0003] During the factory production and maintenance of aviation tires, care products are sprayed on the tire surface. The current spraying work is carried out by using a spray gun on the surface of the removed tire, and at the same time, the tire is rolled or flipped so that the tire surface can be fully sprayed and maintained.

[0004] Since aviation tires need to carry the aircraft, different from traditional vehicle tires, aviation tires are very heavy. During the spraying work, it is necessary to frequently flip and roll the aviation tires placed on the ground, which requires a lot of effort from multiple workers to complete, and there may also be safety accidents when rotating and flipping the heavy aviation tires.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 - Figure 6 As shown, a spraying device for aviation tires with an adjustment structure includes an operating table 1. Mounting plates 2 are fixedly connected to the four corners of the bottom of the operating table 1. A fixing mechanism is arranged at the front of the operating table 1. The fixing mechanism includes a moving column 3. A moving groove 4 is opened at the front of the moving column 3. Both sides inside the moving groove 4 are rotatably connected with a screw 5. One end of the moving column 3 is provided with a motor 6. The motor 6 is fixedly connected to the moving column 3, and the output end of the motor 6 penetrates the moving column 3 and is fixedly connected to one end of the screw 5. The outer sides of both ends of the screw 5 are threadedly connected to one ends of two groups of moving plates 7. A support seat 8 is fixedly connected to the front of the moving plate 7, and tires 9 are arranged outside the two groups of support seats 8;

[0025] During operation, since the aviation tire 9 needs to carry the aircraft, different from traditional vehicle tires 9, the weight of the aviation tire 9 is also very large. During the spraying operation, the aviation tire 9 placed on the ground needs to be frequently flipped and rolled, which requires a lot of effort from multiple workers to complete. Moreover, when the relatively heavy aviation tire 9 is rotated and flipped, it may also cause safety accidents. Place the tire 9 outside the two sets of support seats 8, turn on the motor 6, and the motor 6 drives the screw rod 5 to rotate. At this time, the moving plates 7 at both ends of the screw rod 5 move towards both ends of the screw rod 5 simultaneously, and drive the two sets of support seats 8 to move towards both ends. In this way, the two sets of support seats 8 can be closely attached to the inner side of the tire 9, and the static friction formed by the close fit of the friction pads 11 on the outside of the support seats 8 and the inner side of the tire 9 realizes the fixation of the tire 9. At this time, the spraying equipment can be used to perform the spraying operation on the surface of the tire 9.

[0026] Furthermore, as Figure 3 shown, an obstruction post 10 is fixedly connected to the outer side of the middle of the screw rod 5, and the threads opened at both ends of the screw rod 5 are opposite;

[0027] During operation, the obstruction post 10 can prevent the two sets of moving plates 7 from colliding, and the opposite threads at both ends of the screw rod 5 can make the moving plates 7 threadedly connected to the outer sides of both ends of the screw rod 5 move towards each other simultaneously when the screw rod 5 rotates.

[0028] Furthermore, as Figure 3 shown, the shape of the support seat 8 is a semi-hollow cylinder, and the shapes and sizes of the two sets of support seats 8 are the same. A friction pad 11 is fixedly connected to the outside of the support seat 8;

[0029] During operation, the two sets of support seats 8 being in the shape of semi-hollow cylinders can squeeze the inner side of the tire 9 when moving to corresponding positions, thereby realizing the fixation of tires 9 of different sizes. The friction pad 11 increases the static friction with the inner side of the tire 9 to prevent the tire 9 from rotating and falling off.

[0030] Furthermore, as Figure 3 and Figure 4 shown, one end of the moving column 3 is fixedly connected with an L-shaped column 12, one side of the L-shaped column 12 is fixedly connected with a guide rod 13, and one end of the guide rod 13 penetrates through the two sets of moving plates 7 and is fixedly connected with a stop block 14;

[0031] During operation, the guide rod 13 can prevent the moving plate 7 from rotating together with the screw rod 5 when the screw rod 5 rotates. By the guide rod 13 penetrating through the moving plate 7, the rotational tendency of the moving plate 7 can be hindered, so that the moving plate 7 moves as the screw rod 5 rotates.

[0032] Furthermore, as Figure 5 and Figure 6As shown in the figure, two sets of connecting columns 15 are fixedly connected to the rear of the moving column 3. The rear of the connecting column 15 is fixedly connected to a rotating plate 16. A circular groove 17 is opened at the front of the operating table 1. The rotating plate 16 is arranged in the circular groove 17. The circular groove 17 and the rotating plate 16 are adapted to each other. A hollow retaining column 18 is fixedly connected to the outer side of the front part of the circular groove 17;

[0033] During operation, the rotating plate 16 can rotate within the circular groove 17. The hollow retaining column 18 can prevent the rotating plate 16 from falling out of the circular groove 17 and will not hinder the rotation of the fixing mechanism.

[0034] Furthermore, as Figure 5 and Figure 6 shown, a through hole 19 is opened inside the circular groove 17. A rotating rod 20 is arranged inside the through hole 19. One end of the rotating rod 20 is fixedly connected to the rear of the rotating plate 16, and the other end of the rotating rod 20 passes through the through hole 19 and is fixedly connected to a rotating handle 21;

[0035] During operation, if it is necessary to rotate the tire 9, the rotating handle 21 can be rotated. The rotation of the rotating handle 21 will drive the rotating rod 20 and the rotating plate 16 to rotate, thereby driving the fixing mechanism to rotate. In this way, the tire 9 fixed on the fixing mechanism can rotate. The staff can conveniently complete the rotation of the tire 9 alone for spraying work and can check whether the spraying is sufficient to prevent missed spraying positions.

[0036] Working principle: Since the aviation tire 9 needs to carry the aircraft, different from traditional vehicle tires 9, the weight of the aviation tire 9 is also very large. During spraying work, it is necessary to frequently flip and roll the aviation tire 9 placed on the ground. This requires a lot of effort from multiple staff members to complete. Moreover, when the heavy aviation tire 9 is rotated and flipped, it may also cause safety accidents. Place the tire 9 outside the two sets of support seats 8, turn on the motor 6. The motor 6 works to drive the screw rod 5 to rotate. At this time, the moving plates 7 at both ends of the screw rod 5 move towards both ends of the screw rod 5 at the same time and drive the two sets of support seats 8 to move towards both ends. In this way, the two sets of support seats 8 can be closely attached to the inner side of the tire 9. The static friction formed by the close attachment of the friction pads 11 on the outer side of the support seats 8 to the inner side of the tire 9 realizes the fixation of the tire 9. At this time, the spraying equipment can be used to spray the surface of the tire 9. If it is necessary to rotate the tire 9, the rotating handle 21 can be rotated. The rotation of the rotating handle 21 will drive the rotating rod 20 and the rotating plate 16 to rotate, thereby driving the fixing mechanism to rotate. In this way, the tire 9 fixed on the fixing mechanism can rotate. The staff can conveniently complete the rotation of the tire 9 alone for spraying work and can check whether the spraying is sufficient to prevent missed spraying positions.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, similar improvements, etc. made within the scope of the theory and principles of the present utility model shall be included within the scope of protection of the present utility model.
