Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a replaceable tread structure for a non-pneumatic industrial tire. Background Technology

[0002] Non-pneumatic tires for industrial and mining operations are tires with a non-pneumatic structure specifically designed for complex and harsh working environments such as mines, factories, and construction sites. Their core feature is that they do not rely on compressed air to support the load. The replaceable tread structure allows for the separation and repeated installation and removal of the tread from the tire body.

[0003] In the existing technology, the replaceable tread structure of some non-pneumatic tires for industrial and mining mainly consists of bolt fastening equipment. Compressed air drives the internal impact mechanism to operate. When replacing the tread, the socket of the bolt wrench is aligned with the bolt connecting the tire body and the tread.

[0004] While the replaceable tread structure of some non-pneumatic industrial tires has solved the problem of tire blowouts, the tread is often integrated with the tire body. When the tread wears down to a certain extent, the entire tire needs to be replaced, resulting in resource waste. Moreover, the replacement cost is high and the time is long, which affects the efficiency of industrial and mining operations. Therefore, a replaceable tread structure for non-pneumatic industrial tires is proposed to solve the above problems. Utility Model Content

[0026] The telescopic assembly 32 includes an auxiliary ring 321, which is an annular structure with an inner wall curvature adapted to the ball 34 to constrain its position. The auxiliary ring 321 is internally slidably connected to the outside of the cylinder a31 and can slide along the axial direction of the cylinder a31 to adjust its fit with the ball 34. A spring a322 is fixedly connected to the bottom inner wall of the auxiliary ring 321. The spring a322 is a tension spring and is initially slightly tensioned to provide a reset force for the auxiliary ring 321. A moving block a323 is slidably connected to the inner wall of the cylinder a31. The moving block a323 is a disc-shaped structure with chamfered edges and can move smoothly along the axial direction of the inner wall of the cylinder a31. A spring b324 is sleeved at the bottom of the moving block a323. The spring b324 is a reset spring and can buffer the impact force between the moving block a323 and other components. The outer surface of the cylinder b35 slides... Connected to the inner wall of cylinder a31, it can reciprocate along the inner wall of cylinder a31 to achieve locking and unlocking switching. The outer surfaces of multiple balls 34 are slidably connected to the inner wall of auxiliary ring 321, and can roll between the inner wall of auxiliary ring 321 and the outer wall of cylinder b35 to adjust the locking state. The inner surface of spring a322 is slidably connected to the outer surface of cylinder a31, and can move synchronously with auxiliary ring 321 to ensure continuous elasticity. The inner surface of tire body 2 is slidably connected to the outer surface of multiple cylinders b35, and can achieve a stable connection and fixation with quick release mechanism 3 through the movement of cylinder b35.

It is internally slidably connected to the outside of the cylinder a31 and can slide along the axial direction of the cylinder a31 to adjust its fit with the ball 34. A spring a322 is connected to the bottom inner wall. This tension spring is initially slightly tensioned and can provide a reset force for the auxiliary ring 321.

Multiple balls 34 are externally connected to the inner wall of auxiliary ring 321 and can roll between the two to adjust the locking state. The inner part of spring a322 slides against the outer part of cylinder a31 and moves synchronously with auxiliary ring 321 to maintain elasticity. Multiple cylinders b35 are internally connected to the tire body 2 and are moved by cylinder b35 to achieve a stable connection with quick release mechanism 3. A circular head 39 with a smooth surface and which can be used as a handle for quick disassembly is fixed to the bottom of cylinder a31.

[0028] The auxiliary mechanism 4 includes multiple fixing blocks 41. Each fixing block 41 has a cuboid structure and high hardness to ensure connection strength. The tops of the fixing blocks 41 are fixedly connected to the front and rear sides of the tread module 1, allowing them to move synchronously with the tread module 1. A circular ring a42 is fixedly connected to the bottom of each fixing block 41. The circular ring a42 has a ring-shaped structure and a smooth inner wall to reduce sliding resistance. A circular rod 43 is slidably connected inside the circular ring a42. The circular rod 43 has a solid cylindrical structure and a galvanized surface to prevent rust. A telescopic spring 44 is sleeved on the outside of the circular rod 43. The telescopic spring 44 is a cylindrical helical spring that is initially naturally extended to provide a restoring force. A circular ring b45 is slidably connected to the outside of the circular rod 43. The circular ring b45 has a ring-shaped structure. Furthermore, it is coaxially set with the ring a42 to ensure sliding coaxiality. The front side of the ring b45 is fixedly connected to the moving rod 46. The moving rod 46 is a long strip rod structure with anti-slip texture at one end for easy operation. The outside of the moving rod 46 is slidably connected to the sliding plate 47. The sliding plate 47 is a plate structure with a groove inside to limit the sliding direction of the moving rod 46. The top of the sliding plate 47 is fixedly connected to the outside of the tread module 1, and can form an integrated support with the tread module 1. One end of the round rod 43 is fixedly connected to the protrusion 48. The protrusion 48 is a plate structure and is made of wear-resistant metal to enhance the engagement stability. The other end of the round rod 43 is fixedly connected to the press block 49. The press block 49 is a long plate structure with anti-slip embossed texture on the outer surface for easy manual pressing operation.

[0029] Specifically, the auxiliary mechanism 4 includes a cuboid, high-hardness fixing block 41, which is fixed to the front and rear sides of the tread module 1 and moves synchronously. The bottom is fixed to an annular ring a42 with a smooth inner wall. Inside the annular ring a42, a solid cylindrical rod 43 with a galvanized and rust-proof surface is slidably connected. A cylindrical spiral telescopic spring 44 with initial natural extension and restoring elasticity is sleeved on the outside. An annular ring b45 coaxial with the annular ring a42 is slidably connected to the outside of the rod 43. A long strip-shaped moving rod 46 with anti-slip texture at one end is fixed to the front side of the rod. A plate-shaped sliding plate 47 with a groove that can limit the sliding direction is slidably connected to the outside of the moving rod 46. The top of the sliding plate 47 is fixed to the outside of the tread module 1 and forms an integrated support. One end of the rod 43 is fixed to a plate-shaped, wear-resistant metal protrusion 48 to increase the locking stability, and the other end is fixed to a long plate-shaped, anti-slip textured button 49 for easy manual pressing operation.

[0030] The implementation principle of this application embodiment is as follows: After the bottom of the tread module 1 is attached to the corresponding mounting position of the tire body 2, the circular head 39 is pushed to make the cylinder a31 slide into the tire body 2. The cylinder a31 and the circular head 39 move synchronously. At the same time, the cylinder b35, which is slidably connected to its inner wall, also moves into the tire body 2, forming a preliminary radial positioning. The cylinder a31 and the cylinder b35 move towards each other. The auxiliary ring 321 compresses the spring a322 and moves synchronously, causing the ball 34 to be released from its restriction. During the continuous sliding of the cylinder a31, the moving block b37 and the moving block a323 come into contact. Due to the spring b324 and the spring c38, the cylinder b35 slides inside the cylinder a31. The auxiliary ring 321 is released, and the ball 34 is reset to the top of the ball 34 with the help of the spring a322. When the ball 34 is engaged between the inner wall of the auxiliary ring 321 and the annular groove 36, a bidirectional lock is formed with the annular groove 36, and finally a stable connection between the cylinder a31 and the tire body 2 is achieved, thereby completing the fixation of the tread module 1 and the tire body 2.

[0031] The connection between tread modules 1 is achieved by fixing blocks 41 to the tread modules 1. By operating the push block 49 inward, the push block 49 drives the round rod 43 to move inward. The telescopic spring 44 outside the round rod 43 is acted upon to extend and retract between the rings a42. Since the rings a42 are fixed to the fixing blocks 41, the protrusion 48 also moves inward. The connecting part of another tread module 1 is provided with a groove. When the force applied to the push block 49 is released, the protrusion 48 resets and fits into the groove of the connecting part of another tread module 1, forming a connection between the tread modules 1. The connection between the tread modules 1 can also be released by moving the rod 46.
