Description

Technical Field

[0001] This utility model belongs to the field of rubber machinery technology, specifically relating to an agricultural radial tire storage vehicle. Background Technology

[0002] Agricultural radial tires range in diameter from 16 inches to 54 inches, a wide range that allows for various storage methods, but single-layer storage is most common. Vehicles storing semi-finished products in the second stage occupy a large area, wasting workshop transfer space, increasing logistics difficulties, and easily causing congestion in workshop logistics channels, thus affecting normal production at each stage. Furthermore, the storage methods for semi-finished products in the second stage are divided into vertical and horizontal storage, depending on the diameter and cross-sectional width. Vertical storage is prone to causing damage and deformation to the bezel, while horizontal storage effectively prevents damage and deformation to the bezel during the hanging process.

[0003] Chinese Patent CN222474745U discloses a storage rack specifically for tire mold blocks, comprising a main structure and an auxiliary structure. The auxiliary structure is located behind the main structure. The main structure includes a protective frame, a support plate, and support legs. The support plate is fixedly installed at the lower end of the inner end of the protective frame, and the support legs are movably installed at the upper end of the support plate. The block storage tray is fixedly installed at the upper end of the support legs. This storage rack for tire mold blocks, by installing the main structure, allows users to optimize the storage space inside the protective frame, enabling the storage of more tire mold blocks, reducing warehousing costs for inner tube manufacturers, improving warehouse space utilization, and lowering production costs. It features a simple and practical structure, low processing difficulty, and accurate positioning, further reducing warehousing and logistics costs for inner tube manufacturers. However, the aforementioned device cannot store large-sized semi-finished agricultural radial tires and requires manual pulling out of the stored tires, resulting in high labor intensity. Therefore, there is an urgent need for those skilled in the art to solve the above-mentioned technical problems. Summary of the Invention

[0004] This invention aims to solve the problem that existing technologies cannot store large-sized semi-finished agricultural radial tires and require manual pulling out of the stored tires, which is labor-intensive.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] An agricultural radial tire storage vehicle includes a pallet, a frame, a drive motor, a pallet rack, a slide rail, a rotating screw, and a rotating sleeve;

[0007] The pallet includes an upper pallet and a lower pallet. The upper pallet is mounted on the top of the vehicle frame. The slide rails are mounted on both sides inside the vehicle frame. The pallet frame is mounted on the slide rails. The lower pallet is slidably mounted on the pallet frame.

[0008] The power output end of the drive motor is connected to the rotating lead screw, the rotating lead screw is connected to the rotating sleeve, the drive motor is fixed inside the vehicle frame, and the rotating sleeve is fixed to the bottom of the lower tray.

[0009] By adopting the above technical solution, and through the combined use of a drive motor, a rotating lead screw, and a rotating sleeve, the lower pallet achieves automatic extension and retraction, eliminating the need for manual operation, thus improving work efficiency and reducing the labor intensity of workers. The design of the upper and lower pallets allows for multi-layer storage within a limited space, increasing storage capacity, while providing greater flexibility to accommodate agricultural radial tires of different sizes and types. The slide rails are installed on both sides inside the frame, allowing the pallet frame to move smoothly along them. This method not only ensures the stability and reliability of the pallets but also effectively utilizes the internal space of the frame, improving space utilization. The drive motor is directly connected to the rotating lead screw, and then fixed to the bottom of the lower pallet via the rotating sleeve. This design ensures more direct and stable force transmission, enhancing the stability and safety of the entire system.

[0010] Furthermore, the bottom of the lower tray is also provided with auxiliary wheels, connecting rods, and tension springs;

[0011] The connecting rod is hinged to the bottom of the lower tray, and a tension spring is provided between the connecting rod and the lower tray. The auxiliary wheel is installed at the end of the connecting rod.

[0012] By adopting the above technical solution, the auxiliary wheels reduce friction when the pallet moves on the slide rail, making the movement of the lower pallet smoother. This is especially important for operations involving frequent tire storage and retrieval, as it not only improves work efficiency but also reduces equipment wear. The connecting rod is hinged to the bottom of the lower pallet and connected by a tension spring. This design allows the auxiliary wheels to automatically adjust their position according to the unevenness of the ground, thus maintaining good contact with the ground. This mechanism increases the flexibility and adaptability of the entire system, ensuring smooth operation even on less-than-ideal surfaces. The tension spring not only helps the auxiliary wheels maintain contact with the ground but also provides some shock absorption.

[0013] Furthermore, the frame is also provided with a limiting pin, which is movably inserted into one side of the frame, and the installation position of the limiting pin is adapted to the lower tray.

[0014] By adopting the above technical solution, the limit pin can be inserted when the lower pallet moves to a designated position, locking the pallet's position and effectively preventing accidental pallet slippage due to misoperation or external factors. This is particularly important for ensuring operator safety. During tire loading and unloading or other operations, the limit pin ensures the lower pallet remains stable, reducing the risk of equipment shaking or tipping due to pallet movement. Especially when handling heavy goods, the limit pin allows for precise control of the lower pallet's stopping position, ensuring the pallet accurately stops in the same position each time, improving operational consistency and accuracy. This is especially advantageous for operations requiring frequent access to items in specific locations. The limit pin design is typically simple and easy to use, allowing operators to quickly insert and remove it without complex adjustments. This not only saves time but also reduces operational difficulty, enabling operators of varying experience levels to use the equipment efficiently.

[0015] Furthermore, the bottom of the vehicle frame is equipped with omnidirectional wheels and directional wheels;

[0016] The directional wheels are installed on both sides of the bottom of the frame, and the swivel wheels are installed between the directional wheels. A brake is installed on the directional wheel and is hinged to the directional wheel. Pressing down on the brake locks the directional wheel, and lifting the brake unlocks the directional wheel.

[0017] By adopting the above technical solution, the omnidirectional wheels allow the frame to move in any direction, greatly improving the mobility of the equipment and making turning and moving in confined spaces much easier. The directional wheels ensure stability during straight-line travel, making them particularly suitable for situations requiring long-term, straight-line transport of heavy objects. This combined design maintains both flexibility and stability; the directional wheels are locked or unlocked by pressing down or lifting the brake, making operation simple and quick. This mechanism ensures safety when parked or in a fixed position, avoiding accidents that may be caused by accidental slippage. When making precise position adjustments, locking the directional wheels reduces unnecessary movement and improves operational accuracy.

[0018] Furthermore, the upper tray is bolted to the top of the frame.

[0019] By adopting the above technical solution and using bolts for fixing, a more robust and reliable connection point can be provided compared to other forms of connection, ensuring a tight connection between the upper pallet and the frame. The bolt-fixed structure can effectively resist vibration during transportation, avoiding loosening or damage caused by vibration, and ensuring long-term stable operation of the equipment. When the equipment needs to be repaired, maintained, or parts replaced, the bolts can be quickly removed with simple tools, making it easy to remove the upper pallet, which greatly improves maintenance efficiency. This design supports modular assembly, and the configuration of the upper pallet can be flexibly adjusted according to actual needs to adapt to the storage requirements of different tire models or sizes.

[0020] Furthermore, the rotating lead screw is fitted into the rotating lead sleeve, and the rotating lead sleeve is fixed to the bottom of the lower tray.

[0021] By adopting the above technical solution, the precise cooperation of the lead screw and sleeve can achieve fine adjustment of the equipment height or position, providing a more refined operating experience. The high-quality lead screw and sleeve combination can ensure the accuracy of the action execution and reduce the position deviation caused by mechanical backlash. This design provides stable support for the lower tray, ensuring that it can withstand the corresponding load without deformation. The lead screw and sleeve made of suitable materials have good wear resistance and can maintain stable performance and extend service life during long-term use.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model uses a drive motor to rotate a lead screw, which in turn causes a connected lead screw sleeve to extend or retract the lower tray along a slide rail from inside the vehicle frame. This achieves automated storage and retrieval of semi-finished tires without the need for manual operation, significantly reducing the labor intensity of workers. The auxiliary wheels, connecting rods, and tension springs make the movement of the tray on the slide rail smoother and adaptable to uneven ground. The design of the limit pin ensures the stability of the tray position and avoids safety hazards caused by misoperation.

[0024] 2. The design of the upper and lower pallets of this utility model allows for multi-layer storage on the same equipment, improving space utilization. It is particularly suitable for storing large-sized agricultural radial tires. Compared with the traditional single-layer storage method, it effectively reduces the floor space, improves the space utilization of the workshop, and can flexibly adapt to the storage needs of agricultural radial tires of different sizes and types. It enhances the application range and flexibility of the equipment. The modular assembly method supports configuration adjustment according to actual needs, further improving the convenience of use.

[0025] 3. This utility model adopts a horizontal storage method, which effectively prevents problems such as damage and deformation of the semi-finished tire bead, ensuring product quality. Compared with the vertical storage method, it can better protect the integrity of the semi-finished products. Due to the compact double-layer storage design, the vehicle footprint is reduced, avoiding congestion in the logistics transportation channel and improving logistics transportation efficiency. The design of transporting two semi-finished products at a time further optimizes the logistics process and reduces the overall operating cost. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0031] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3As can be seen, this utility model discloses an agricultural radial tire storage vehicle, including an upper pallet 2 which is fixedly installed on the top of the frame 1 by bolts to form the upper support platform of the storage vehicle, a lower pallet 3 which is slidably installed on a pallet frame 4, and the pallet frame 4 is connected to the inside of the frame 1 through slide rails 6 on both sides, so that the lower pallet 3 can move horizontally along the slide rails 6. A drive motor 5 is fixedly installed inside the frame 1, and its power output end is directly connected to a rotating lead screw 13. The rotating lead screw 13 and the rotating sleeve 14 are fitted inside the rotating sleeve 14 to form a helical transmission pair. The rotating sleeve 14 is rigidly fixed to the bottom of the lower pallet 3. When the drive motor 5 starts, the lead screw 13 rotates, causing the lead sleeve 14 and the lower tray 3 to move linearly along the slide rail 6. One end of the connecting rod 15 is hinged to the bottom of the lower tray 3, and the other end is fitted with an auxiliary wheel 10. The tension spring 7 connects the connecting rod 15 and the lower tray 3, maintaining the contact between the auxiliary wheel 10 and the ground through elastic force, providing support and reset during movement. The limiting pin 12 is movably inserted into a preset hole on one side of the frame 1, its position corresponding to the movement path of the lower tray 3. When the limiting pin 12 is inserted, it restricts the sliding range of the lower tray 3, achieving fixation. The directional wheel 9 and the universal wheel 8 are symmetrically installed on both sides of the bottom of the frame 1, providing directional movement. The universal wheel 8 is installed between the two directional wheels 9, enhancing steering flexibility. The brake 11 is hinged to the directional wheel 9, locking it by pressing down and unlocking it by lifting. The bolted connection between the upper tray 2 and the frame 1 ensures structural stability and facilitates disassembly and maintenance. The drive motor 5 drives the rotating lead screw 13 to rotate, and the rotational motion is converted into the linear motion of the lower tray 3 through the lead sleeve 14. The lower tray 3 extends and retracts horizontally under the guidance of the slide rail 6, and the auxiliary wheel 10 and tension spring 7 provide movement stability. The limit pin 12 and the brake 11 control the position of the tray and the wheel locking respectively, so as to realize the flexible storage and transportation of tires.

[0033] Working principle: When tires are stored horizontally, the tire sidewalls and treads are evenly stressed, avoiding localized pressure deformation of the tire sidewalls caused by long-term vertical storage. When tires are laid flat, the contact area between the tire tread and the pallet is large, dispersing pressure and reducing the risk of rubber aging or cracking caused by concentrated stress. The multi-layer design of the upper pallet 2 and lower pallet 3 allows for the stacking of multiple tires. Combined with the horizontal fixing structure, it prevents tires from rolling or tipping over. By controlling the drive motor 5, the rotating screw 13, which is directly connected to its power output end, is rotated. The rotating screw 13 and the rotating sleeve 14 fixed at the bottom of the lower pallet 3 form a helical pair, which... The rotational motion of the lead screw is converted into the horizontal linear motion of the lead sleeve and the lower tray 3. The lower tray 3 extends and retracts smoothly under the guidance of the slide rail 6 of the tray frame 4, avoiding deviation or jamming. There is no need for manual pushing or pulling of the tray; the extension or retraction of the lower tray 3 can be achieved simply by operating the motor, greatly reducing physical exertion. The motor drive can precisely control the movement distance of the tray, facilitating alignment of storage positions or loading and unloading of tires. The auxiliary wheel 10 and the tension spring 7 work together so that when the lower tray 3 extends outward, the auxiliary wheel 10 at the end of the connecting rod 15 hinged to its bottom remains in contact with the ground under the elastic tension of the tension spring 7, forming an additional support point. To prevent the lower pallet 3 from sagging or tilting due to excessive load, when the pallet retracts, the tension spring 7 pulls the connecting rod 15 and the auxiliary wheel 10 to reset, avoiding interference with the vehicle body structure. After the limit pin 12 is inserted into the preset hole on the side of the frame 1, it limits the maximum extension length of the lower pallet 3, preventing excessive slippage that could lead to instability or mechanical damage. By pressing down the brake 11, the directional wheel 9 is locked to ensure that the vehicle remains stationary when loading or unloading tires or moving the pallet, preventing accidental slippage. The directional wheels 9 on both sides of the bottom of the frame 1 provide linear stability, while the swivel wheel 8 in the middle enhances steering flexibility, allowing the vehicle to easily maneuver in confined spaces. Steering allows for quick switching between transport and operation modes: After the brake 11 is unlocked, the vehicle can move freely; after the brake is locked, it switches to a stable operation mode, placing the tires horizontally on the upper pallet 2 and lower pallet 3, starting the drive motor 5, and extending the lower pallet 3 outward along the slide rail 6, with the auxiliary wheel 10 contacting the ground to provide support. In the extended state, tires can be easily loaded and unloaded; the pallet position is fixed by the limit pin 12 to ensure safety, the motor reverses, and the lower pallet 3 retracts into the frame 1, saving space and facilitating transport. The vehicle is transferred to the target position by the casters 8 and directional wheels 9, and the brake 11 locks the wheels to complete the fixation.

Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
