Description

Technical Field

[0001] The invention belongs to the technical field of tire storage, and in particular relates to a double-layer anti-dumping tire storage rack. Background Art

[0002] Aircraft tires must be stored upright, but prolonged exposure to stress in the same position can cause tire deformation and irreversible damage. Therefore, to prevent tire deformation, they should be rotated regularly to change the stress point and ensure even distribution of force.

[0003] Conventional storage of aircraft tires is often done in a single-layer format, using wooden or steel frames, suspended on two axles. This method not only reduces space utilization but also requires regular manual tire rotation, which is time-consuming, labor-intensive, and inconvenient. Another option is to place the tires vertically on the ground, but this storage method only allows for short-term storage and is not suitable for long-term storage. Furthermore, narrow tires are prone to tipping over when stored vertically, potentially damaging the tires. Summary of the Invention

Detailed implementation manners

[0020] In order to enable those skilled in the art to have a clearer understanding and knowledge of the present invention, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described below are only used to explain the present invention for easy understanding, and the technical solutions provided by the present invention are not limited to the technical solutions provided by the following embodiments, nor should the technical solutions provided by the embodiments limit the protection scope of the present invention.

[0021] Embodiment As Figures 1 to 3As shown in the figure, this embodiment provides a double-layer anti-tipping tire storage shelf, which takes the frame-type shelf body 1 as the carrier. The frame-type shelf body 1 adopts a frame structure, and its four sides are all open structures. The material can be conventional metal materials such as stainless steel. Cross beams are arranged in the middle of the front and rear sides of the frame-type shelf body 1. Based on the cross beams, the frame-type shelf body 1 is divided into upper and lower layers, namely the upper part and the lower part. Four tire storage positions are arranged in the frame-type shelf body 1. Specifically: the upper part is two tire storage units arranged side by side, and the lower part is two tire storage units arranged side by side. In the horizontal direction, there is a gap between the two tire storage units. Among them, an operation platform 18 is arranged between the two tire storage units in the upper part. The operation platform 18 is fixedly connected to the frame-type shelf body 1, for example: welding, bolt connection. The operation platform 18 is used for personnel to stand on to facilitate the picking and placing of the tires stored in the upper layer. In a further preferred solution, a ladder corresponding to the operation platform 18 (not shown in the figure) can also be arranged on the side of the frame-type shelf body 1 to facilitate the up and down movement of personnel. At the same time, the picking and placing of the upper-layer tires can also be realized in cooperation with a hoisting device; Slope pads 19 are arranged on the left and right sides at the lower end of the frame-type shelf body 1 for the picking and placing of the lower-layer tires 22. During operation, the tires 22 can be pushed onto the tire storage shelf through the triangular pedal.

[0022] The space between the two tire storage units in the lower part is used to arrange the driving motor 9, and the driving motor 9 is fixed on the frame-type shelf body 1.

[0023] In this embodiment, the tire storage unit includes a main support rotating shaft 2 and a secondary support rotating shaft 3 which are located below and relatively spaced on the left and right sides, a clamping assembly 4 which is arranged on the front and rear sides of the main support rotating shaft 2 and the secondary support rotating shaft 3 and can be adjusted and moved, a support optical axis 5 which is arranged at the upper end of one side of the tire storage unit, and a toothed pitch adjustment plate 8 which is arranged at the lower end of the other side obliquely opposite to the support optical axis 5. The upper end of the clamping assembly 4 is sleeved on the support optical axis 5 and can slide, and its lower end is fixed on the toothed pitch adjustment plate 8. The support optical axis 5 and the toothed pitch adjustment plate 8 are both fixedly installed on the frame-type shelf body 1, and one support optical axis 5 and one toothed pitch adjustment plate 8 correspond to one clamping assembly 4.

[0024] Structure of the main support rotating shaft 2 and the auxiliary support rotating shaft 3: Both the main support rotating shaft 2 and the auxiliary support rotating shaft 3 are installed on the main body 1 of the frame-type shelf through support bearings; preferably, the main support rotating shaft 2 and the auxiliary support rotating shaft 3 are roller shafts with rubber coating on the outside, and the rubber coating materials are, for example, rubber, polyurethane, silicone, etc. When storing, the tires are placed vertically between the main support rotating shaft 2 and the auxiliary support rotating shaft 3, and the running surface of the tires abuts against the main support rotating shaft 2 and the auxiliary support rotating shaft 3. The rubber coating on the outside of the roller shaft adopts the cold rubber coating technology, without defects such as chipping and cracking, and is more reliable and has higher maintainability at the same time; both the main support rotating shaft 2 and the auxiliary support rotating shaft 3 can rotate. Among them, the main support rotating shaft 2 is the driving shaft, which is driven by the driving motor 9, and the auxiliary support rotating shaft 3 is the driven shaft, and the rotation of the tires is driven by the rotation of the main support rotating shaft 2.

[0025] Considering the storage problems of different tire sizes, in this embodiment, a support bracket 7 is provided on the outer side of the main body 1 of the frame-type shelf. The support bracket 7 is fixedly connected to the main body 1 of the frame-type shelf, for example, by welding. A number of horizontally spaced mounting holes are provided at both ends of the support bracket 7. For example, two mounting holes are provided at one end, and there is a certain distance (such as 1 cm, 2 cm) between the two mounting holes. The mounting holes at both ends should be symmetrically arranged in pairs. A vertical bearing 6 is installed through the mounting holes, so that the vertical bearing 6 can be installed at different positions, and the auxiliary support rotating shaft 3 is installed on the support bracket 7 through the vertical bearing 6. Thus, the distance between the auxiliary support rotating shaft 3 and the main support rotating shaft 2 can be adjusted (realized based on the installation of the vertical bearing 6 at different positions), so as to be compatible with the storage of tires of different sizes.

[0026] In a further preferred solution, a support bracket 7 is also provided on the outer side of the upper end of the main body 1 of the frame-type shelf. This support bracket 7 is used to install the upper support optical shaft 5, and the lower support optical shaft 5 (the support optical shaft 5 corresponding to the lower tire storage unit) is installed on the support bracket 7 located in the middle outer layer of the main body 1 of the frame-type shelf.

[0027] Drive structure for tire rotation: In this embodiment, one driving motor 9 is used to realize the rotation of all the tires stored in the four tire storage units. Its structure is as follows: The output end of the driving motor 9 is connected to the main support rotating shaft 2 of the lower tire storage unit through a horizontal chain 10. The main support rotating shaft 2 of the upper tire storage unit is connected to the main support rotating shaft 2 of the lower tire storage unit through a vertical chain 11, and the main support rotating shaft 2 of the upper tire storage unit is driven by the main support rotating shaft 2 of the lower tire storage unit; among them, two sprockets are sleeved on the output end of the driving motor 9. One sprocket is connected to one end of the left horizontal chain 10, and the other sprocket is connected to one end of the right horizontal chain 10. The other ends of the left horizontal chain 10 and the right horizontal chain 10 are respectively connected to the main support rotating shaft 2 of the lower tire storage unit.

[0028] The other end of the horizontal chain 10 on the left is connected to the main support rotating shaft 2 of the lower tire storage unit. Two sprockets are sleeved on the main support rotating shaft 2. One sprocket is connected to the other end of the horizontal chain 10 on the left, and the other sprocket is connected to the lower end of the vertical chain 11 on the left. The upper end of the vertical chain 11 on the left is connected to the main support rotating shaft 2 of the upper tire storage unit. One sprocket is sleeved on the main support rotating shaft 2 for connecting the upper end of the vertical chain 11 on the left. The connection mode of the horizontal chain 10, vertical chain 11 on the right and the main support rotating shaft 2 of the upper tire storage unit is the same as that on the left, so it will not be elaborated here.

[0029] Through the structural arrangement of the above tire rotation drive structure, on the one hand, the electric drive control of tire rotation is realized. Combined with the program control of the drive motor 9 by the PLC, the regular tire rotation control can be achieved. On the other hand, one drive motor 9 can drive the tires stored on the four tire storage units, which simplifies the equipment structure and control and reduces the cost.

[0030] Tire anti-tipping structure: Since the tires are stored vertically, in order to prevent the tires from tipping over, each tire storage unit is equipped with a pair of clamping components 4. The clamping components 4 can move left and right to clamp the tires, thus realizing the anti-tipping of the tires. The specific structure is as follows: The clamping component 4 includes an inclined rod 12, a first triangular rod 13 arranged on one side of the inclined rod 12, and a second triangular rod 14 arranged on the other side of the inclined rod 12. A linear sliding bearing 15 sleeved on the support optical axis 5 is arranged at the upper end of the inclined rod 12, and a connecting baffle 16 clamped on the toothed pitch adjusting plate 8 is arranged at the lower end of the inclined rod 12. Among them, the linear sliding bearing 15 is fixedly installed on the inclined rod 12. The connecting baffle 16, inclined rod 12, first triangular rod 13 and second triangular rod 14 are of an integral structure, and a number of universal balls 17 are also arranged on the inner side surfaces (the surfaces in contact with the tires) of the inclined rod 12, first triangular rod 13 and second triangular rod 14, which can prevent scratching the tires.

[0031] The tooth pitch adjusting plate 8 includes a main body portion 20 and a number of teeth 21 arranged equidistantly on the main body portion 20. The connecting baffle 16 is clamped between two teeth 21. When it is necessary to move the clamping assembly 4, the connecting baffle 16 is taken out from the tooth pitch adjusting plate 8, and the clamping assembly 4 moves along the support optical axis 5. Thus, the positions of the two clamping assemblies 4 can be adjusted. After the positions of the clamping assemblies 4 are adjusted appropriately to clamp the stored tire 22, the connecting baffle 16 is then clamped between the two teeth corresponding to the current position to complete the fixation of the clamping assembly 4. Through the setting of the clamping assembly 4, on the one hand, the tipping of the tire can be prevented, and on the other hand, the number of tires stored on the tire storage unit can be more flexible. After the tire is placed, it can be clamped by the clamping assembly 4 to adapt to the storage of different numbers of tires.

[0032] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
