Description

Technical Field

[0001] This utility model relates to the field of universal joint technology, and in particular to a universal joint for metallurgy. Background Technology

[0002] Universal joints are widely used in metallurgical equipment, machinery manufacturing, and transmission systems, primarily for power transmission between axes at different angles or without alignment. In the metallurgical industry, due to the complex operating environment, universal joints need to withstand significant torque and impact loads, thus requiring high levels of structural stability and ease of assembly and disassembly. To ensure the normal operation of equipment, the maintenance and replacement of universal joints are crucial aspects of metallurgical equipment management.

[0003] Traditional metallurgical universal joints are mainly used to connect the transmission systems of equipment such as rolling mills and continuous casting machines to achieve efficient power transmission. During installation, it is essential to ensure that the flanges at both ends are aligned and the bolts are tightened to guarantee axis concentricity and reduce vibration and impact. During operation, the bearing components should be lubricated regularly to prevent excessive wear. During inspections, attention should be paid to the wear condition of key components such as bushings and cross shafts, and damaged parts should be replaced promptly to ensure stable equipment operation and extend service life.

[0004] Existing universal joints typically use bolts or pins for fixed connections, which are cumbersome to install and disassemble, requiring additional tools or complex procedures, and are not conducive to efficient maintenance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a universal joint for metallurgy, which aims to improve the existing universal joints, which are cumbersome to operate during installation and disassembly and are not conducive to efficient maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a universal joint shaft for metallurgy, comprising a connector, a rotating ring provided on the inner wall of the connector, a roller slidably connected to the inner wall of the rotating ring, a fixing member slidably connected to the outer wall of the roller, a support block slidably connected to the bottom of the fixing member, a screw threadedly connected to the inside of the fixing member, a handle fixedly connected to one end of the screw, a slider rotatably connected to the other end of the screw, and a snap-fit ​​assembly provided inside the slider for assembling and disassembling the fixing member and the support block;

[0007] The locking assembly includes a connecting rod, one end of which is rotatably connected to the inside of the slider, and the other end of which is rotatably connected to a locking block. The outer wall of the locking block is slidably connected to the inside of the fixing member. A reset assembly is provided inside the locking block, which is used to pull the locking block to reset.

[0008] Furthermore, the reset assembly includes a limiting rod, the outer wall of which is slidably connected to the inside of the snap-fit ​​block, and a spring is sleeved on the outer wall of the limiting rod.

[0009] Furthermore, a connector is provided on one side of the outer wall of the support block, a fixed shaft is fixedly connected to one end of the connector, a connecting shaft is provided on one side of the outer wall of the fixed shaft, and an adjustment component is provided at one end of the fixed shaft. The adjustment component is used to adjust the distance between the fixed shaft and the connecting shaft.

[0010] Furthermore, the adjusting component includes a limiting sleeve, one end of which is fixedly connected to one end of the fixed shaft, and a polygonal slide rod is slidably connected inside the limiting sleeve, one end of which is fixedly connected to the inside of the connecting shaft.

[0011] Furthermore, the outer wall of the snap-fit ​​block is slidably connected to the inside of the support block, and the snap-fit ​​block is used to limit the positioning of the fixing member.

[0012] Furthermore, both ends of the spring are fixedly connected to one side of the outer wall of the snap-fit ​​block.

[0013] Furthermore, the end of the connector is disposed on the outer wall of the rotating ring.

[0014] Furthermore, the outer wall of the limiting sleeve is slidably connected inside the connecting shaft, and the connecting shaft is used to limit the limiting sleeve.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the drive handle drives the screw to rotate, which in turn pushes the slider to move. Then, through the transmission action of the connecting rod, the snap-fit ​​block slides inside the fixing part and the support block. At the same time, the spring contracts, realizing the quick assembly and disassembly of the rotating ring and the roller. This makes the assembly and disassembly process of the universal joint shaft more convenient, improves the assembly and disassembly efficiency, reduces the operation time, and avoids the problem of difficult disassembly due to the tightness of the parts in the traditional method.

[0017] 2. In this utility model, the multi-sided slide bar has multiple protrusions on its outer wall, allowing the limiting sleeve to slide freely along the slide bar, thereby adjusting the distance between the connecting parts. This enables the universal joint to adapt to different connection positions, improving the adaptability and practicality of the equipment, ensuring the stability of the connection, and reducing the risk of affecting use due to mismatched connection distances.

[0025] 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 protection scope of the present utility model.

[0026] Reference Figures 1-4 The present invention provides an embodiment of a universal joint shaft for metallurgy, comprising a connector 1, a rotating ring 3 on the inner wall of the connector 1, a roller 5 slidably connected to the inner wall of the rotating ring 3, and a fixing member 4 slidably connected to the outer wall of the roller 5. The roller 5 can roll freely inside the rotating ring 3 to meet the needs of multi-angle transmission. A support block 2 is slidably connected to the bottom of the fixing member 4. The stable support of the support block 2 ensures that the connection of the universal joint shaft is stable and can withstand a large load. A screw 7 is threadedly connected inside the fixing member 4. A handle 6 is fixedly connected to one end of the screw 7. The handle 6 is easy to operate manually, so that the displacement of the screw 7 can be precisely controlled when rotating. A slider 8 is rotatably connected to the other end of the screw 7. A snap-fit ​​assembly is provided inside the slider 8. The snap-fit ​​assembly is used to assemble and disassemble the fixing member 4 and the support block 2.

[0027] The locking assembly includes a connecting rod 9, one end of which is rotatably connected to the inside of a slider 8. When the slider 8 moves, it can drive the connecting rod 9 to rotate. The other end of the connecting rod 9 is rotatably connected to a locking block 12. The outer wall of the locking block 12 is slidably connected to the inside of a fixing member 4. Through the transmission action of the connecting rod 9, the locking block 12 is displaced, thereby unlocking or locking the fixing member 4 and the support block 2. A reset assembly is provided inside the locking block 12. The reset assembly is used to pull the locking block 12 to reset. The reset assembly includes a limiting rod 10, the outer wall of which is slidably connected to the inside of the locking block 12. A spring 11 is sleeved on the outer wall of the limiting rod 10.

[0028] Specifically, the screw 7 is first rotated by the drive handle 6. Since there is a threaded connection between the screw 7 and the fixing part 4, the rotation of the screw 7 can make it move along the thread direction and further push the slider 8 to slide inside the fixing part 4. As the slider 8 moves, one end of the connecting rod 9 will also be displaced, thereby driving the other end of the connecting rod 9 to act on the locking block 12. At this time, the locking block 12 slides inside the fixing part 4. Since the spring 11 is set between the two locking blocks 12, the spring 11 will contract accordingly, thereby causing the locking block 12 to slide synchronously between the fixing part 4 and the support block 2. When the locking block 12 is completely inserted into the interior of the fixing part 4, the operator can pull the fixing part 4 to pull out the rotating ring 3 and the roller 5 together, realizing the disassembly and assembly operation of the connector 1. This structural design makes the disassembly and assembly of the universal joint shaft more convenient, improves the disassembly and assembly efficiency, and effectively reduces the operational difficulties caused by component fastening, thereby improving the maintenance convenience of the equipment.

[0029] Reference Figure 1 and Figure 5 A connector 13 is provided on one side of the outer wall of the support block 2. One end of the connector 13 is fixedly connected to a fixed shaft 14. The fixed shaft 14 is used to provide a connection fulcrum to ensure connection stability. A connecting shaft 15 is provided on one side of the outer wall of the fixed shaft 14. An adjustment component is provided on one end of the fixed shaft 14 to enable the universal joint to adapt to different installation requirements and improve the adaptability of the device. The adjustment component is used to adjust the distance between the fixed shaft 14 and the connecting shaft 15. The adjustment component includes a limiting sleeve 16, one end of which is fixedly connected to the fixed shaft 14. One end of the fixed shaft 14 is slidably connected to the inside of the limiting sleeve 16, and one end of the multi-sided slide rod 17 is fixedly connected to the inside of the connecting shaft 15. The outer wall of the snap-fit ​​block 12 is slidably connected to the inside of the support block 2. The snap-fit ​​block 12 is used to limit the fixing member 4. Both ends of the spring 11 are fixedly connected to one side of the outer wall of the snap-fit ​​block 12. The end of the connecting member 13 is set on the outer wall of the rotating ring 3. The outer wall of the limiting sleeve 16 is slidably connected to the inside of the connecting shaft 15. The connecting shaft 15 is used to limit the limiting sleeve 16.

[0030] Specifically, in actual use, the distance between the two connecting parts 1 can be adjusted by pulling the fixed shaft 14 to slide it to one side according to the actual distance requirements between the connection points. This causes the limiting sleeve 16 to slide along the outer wall of the polygonal slide rod 17, thereby adjusting the distance between the two connecting parts 1. Since the outer wall of the polygonal slide rod 17 has multiple protrusions, the protrusions can fit with the limiting sleeve 16, ensuring that the limiting sleeve 16 maintains a stable connection in different sliding positions. This improves the adaptability between the connecting parts 1, not only adapting to the needs of different equipment specifications and improving the versatility of the universal joint, but also ensuring the stability of the connection through the limiting effect of the protrusions, avoiding operational failures caused by displacement or loosening of the connecting parts, further improving the practicality and reliability of the universal joint in metallurgical equipment.

[0031] Working principle: When the metallurgical universal joint shaft is needed, first drive the handle 6 to drive the screw 7 to rotate. Then, in conjunction with the thread relationship between the screw 7 and the fixing part 4, the screw 7 can drive the slider 8 to slide inside the fixing part 4. Then, the movement of the slider 8 drives one end of the connecting rod 9 to move. At this time, the other end of the connecting rod 9 can drive the locking block 12 to slide inside the fixing part 4. At the same time, the spring 11 will contract between the two locking blocks 12, so that the locking block 12 slides inside the fixing part 4 and the support block 2. When the locking block 12 has completely moved into the interior of the fixing part 4, the fixing part 4 can be pulled to pull out the rotating ring 3 and the roller 5 together, which makes it convenient to disassemble and assemble the connecting part 1.

[0032] In addition, during use, the fixed shaft 14 can be pulled to one side according to the distance of the connection point, thereby causing the limiting sleeve 16 to slide on the outer wall of the polygonal slide rod 17, so as to adjust the distance between the two connecting parts 1. At the same time, since there are multiple protrusions on the outer wall of the polygonal slide rod 17, it can be adapted to different connection positions.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
