Description

Technical Field

[0001] This application relates to the field of mechanical engineering technology, and more specifically, to a conveyor roller table for a hot rolling mill. Background Technology

[0002] A hot rolling mill is a metal processing equipment that heats metal billets to above the recrystallization temperature and uses the pressure of rolls to cause plastic deformation in order to obtain the desired shape, size and properties. It is mainly used in the construction industry, automotive industry and energy industry, etc.

[0003] The hot rolling mill conveyor rollers are the material transport link in the hot rolling production line. Their core function is to smoothly transport high-temperature metal billets or finished products between various processes and connect key units such as heating furnaces, rolling mills, and finishing equipment.

[0004] However, the metal sheets on existing conveyor rollers are mostly fixedly installed. Since the material mainly comes into contact with the side of the metal sheet near the middle of the equipment during the conveying process, this side will be severely worn due to frequent friction and high temperature impact after long-term use, while the other side away from the middle is almost unused, resulting in low overall utilization efficiency of the metal sheet.

[0005] In view of this, we propose a conveyor roller table for a hot rolling mill. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this application proposes a conveyor roller table for a hot rolling mill.

[0007] This application provides a conveyor roller table for a hot rolling mill, comprising: The fixing frame is provided in pairs, and the top of the fixing frame has several placement slots; A cube is slidably disposed on the inner wall of a placement slot. A bearing is installed on one side of the cube. The bearing stator is fixedly connected to the inner wall of the cube. A square shaft is disposed on the inner wall of the bearing. The square shaft and the bearing rotor are plugged into each other. A rotating column is fixedly connected to the end of the square shaft. A first metal plate and a second metal plate slide on the outer wall of the rotating column. A fixing mechanism, located inside the rotating column, is used to position the ends of the first and second metal plates after installation.

[0008] As an optional solution to the technical solution of this application, the fixing mechanism includes a square column that slides through the inner wall of the square shaft, a top block fixedly connected to the end of the square column, two sets of movable grooves opened inside the rotating column, a limit block slidably connected to the inner wall of the movable groove, a gasket fixedly connected to the outer wall of the limit block, and the bottom of the limit block having an inclined structure.

[0009] As an optional solution to the technical solution of this application, the inner wall of the limiting block has two storage slots, the inner side of the movable slot has two fixed blocks, the two ends of the fixed blocks are fixed with elastic ropes, the ends of the elastic ropes are fixedly connected to the bottom wall of the fixed blocks, and the elastic ropes are set close to the inclined surface of the limiting block.

[0010] As an optional solution to the technical solution of this application, the top of the fixed frame is fixedly connected to two rotating shafts, the side walls of the rotating shafts are fixedly connected to mounting plates, the top of the mounting plates is fixedly connected to counterweight plates, and the two ends of the mounting plates are fixedly connected to handles.

[0011] As an optional solution to the technical solution of this application, a friction block is fixedly connected to the end of the square column, and the friction block is set on the side close to the placement groove.

[0012] As an optional solution to the technical solution in this application, the bottom of the fixed frame is fixedly connected to two support legs, the bottom of the support legs is fixedly connected to an mounting plate, and the side wall of the support legs is fixedly connected to two reinforcing frames.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: (1) This application solves the problem that the protective iron sheet on the traditional conveyor roller does not have an adjustment function and is difficult to turn around and change position due to the limitation of the fixing method. As a result, only one side near the middle of the equipment is severely worn due to frequent contact with materials, while the other side is almost unused, resulting in low efficiency of metal sheet use. However, through the sliding fit between the block and the placement groove and the insertion fit between the square shaft and the bearing, the first metal sheet and the second metal sheet can be easily disassembled as a whole and then turned around for installation, so that both sides are worn evenly and the service life is extended.

[0014] (2) This application uses the elastic force of the elastic rope to make the limiting block automatically reset after the top block is released, without the need for manual pressing to reset, which improves the convenience of disassembling or adjusting the first metal plate and the second metal plate.

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-5 This application discloses a conveyor roller of a hot rolling mill, comprising a fixed frame 1, a block 2, and a fixing mechanism 3. Two fixed frames 1 are provided, with several placement slots 11 on the top of each frame 1. A bearing 21 is slidably mounted on the inner wall of each placement slot 11. A bearing 21 is mounted on one side of the block 2, with its stator fixedly connected to the inner wall of the block 2. A square shaft 22 is provided on the inner wall of the bearing 21, and the square shaft 22 is plugged into the rotor of the bearing 21. A rotating column 23 is fixedly connected to the end of the square shaft 22, and a first metal plate 24 and a second metal plate 25 slide on the outer wall of the rotating column 23. These are positioned inside the rotating column 23 to limit the position of the installed ends of the first metal plate 24 and the second metal plate 25. Material is driven by external force to slide on the multiple first metal plates 24 and second metal plates 25. Two support legs 12 are fixedly connected to the bottom of the fixed frame 1, with mounting plates 13 fixedly connected to the bottom of each support leg 12, and two reinforcing frames 14 fixedly connected to the side walls of the support legs 12. First, fix the two fixed frames 1 in the designated positions using the bottom support legs 12 and mounting pieces 13. Then, slide the block 2 along the inner wall of the placement groove 11 at the top of the fixed frame 1, so that the block 2 is stably embedded in the placement groove 11. Next, align the square shaft 22 with the inner wall of the bearing 21 on one side of the block 2. By using the insertion and engagement of the square shaft 22 with the rotor of the bearing 21, the square shaft 22 can rotate flexibly within the bearing 21, thereby driving the rotating column 23 fixed at the end to rotate synchronously. Before the square shaft 22 is engaged, slide the first metal piece 24 and the second metal piece 25 along the outer wall of the rotating column 23 and adjust them to fit. After the appropriate position is determined, the ends of the two metal sheets are positioned by the fixing mechanism 3. This step solves the problem that the protective iron sheets on traditional conveyor rollers do not have an adjustment function and are difficult to turn around and change position due to the limitation of the fixing method. As a result, only the side closer to the middle of the equipment is severely worn due to frequent contact with materials, while the other side is almost unused, resulting in low efficiency of metal sheet use. However, through the sliding fit between the block 2 and the placement groove 11, and the insertion fit between the square shaft 22 and the bearing 21, the first metal sheet 24 and the second metal sheet 25 can be easily disassembled as a whole and turned around for installation, so that both sides are worn evenly and the service life is extended.

[0019] Reference Figures 1-5 The fixing mechanism 3 includes a square column 31 that slides through the inner wall of the square shaft 22. A top block 32 is fixedly connected to the end of the square column 31. Two sets of movable grooves 33 are opened inside the rotating column 23. A limit block 34 is slidably connected to the inner wall of the movable groove 33. A gasket 35 is fixedly connected to the outer wall of the limit block 34. The bottom of the limit block 34 is inclined. A friction block is fixedly connected to the end of the square column 31. The friction block is set on the side close to the placement groove 11. The core function of the fixing mechanism 3 is to limit the ends of the first metal plate 24 and the second metal plate 25 sleeved on the rotating column 23. First, the square shaft 22 is inserted into the bearing 21 of the block 2. At this time, the square column 31, which slides through the inner wall of the square shaft 22, will first press against the inner wall of the block 2 due to its own protruding structure, and continue to push the square shaft 22 deeper into the bearing 21. The square column 31 slides towards the top block 32 due to the reaction force of the inner wall of the block 2, driving the top block 32, which is fixed at the end, to move synchronously. Since the top block 32 is arc-shaped and the rotating column 23 has two sets of movable grooves 33 inside, the bottom of the limiting block 34 in the movable groove 33 is inclined. When the top block 32 moves, it will contact the inclined surface of the limiting block 34, and the two metal plates 25 will be guided by the inclined surface. The limiting block 34 is pushed upward, causing it to extend from the movable groove 33. The extended limiting block 34 abuts against the ends of the first metal piece 24 and the second metal piece 25. The stepped structure of the rotating column 23 helps to fix the metal pieces axially. The gasket 35 on the outer wall of the limiting block 34 increases the contact area with the metal pieces. This step, through the linkage structure of the square column 31, the top block 32 and the limiting block 34, achieves the rapid fixing of the first metal piece 24 and the second metal piece 25. Only the square shaft 22 needs to be pushed to trigger the limiting block 34 to be pushed up, which is convenient to operate. The cooperation between the limiting block 34 and the gasket 35 ensures that the metal pieces are firmly fixed, preventing the first metal piece 24 and the second metal piece 25 from shifting due to vibration or material impact during the conveying process.

[0020] Reference Figures 1-5 The inner wall of the limiting block 34 has two storage slots 341, and the inner side of the movable slot 33 has two fixed blocks 331. The two ends of the fixed blocks 331 are fixed with elastic ropes 332. The ends of the elastic ropes 332 are fixedly connected to the bottom wall of the fixed blocks 331. The elastic ropes 332 are set close to the inclined surface of the limiting block 34. When the top block 32 in the fixing mechanism 3 pushes the limiting block 34 to move upward along the movable slot 33, the storage slots 341 on the inner wall of the limiting block 34 will move synchronously with the limiting block 34 and pull the elastic ropes 332 to deform. When the two limiting blocks 34 need to be reset, the stretched elastic ropes 332 will release elastic potential energy and generate contraction force, pulling the limiting blocks 34 to reset downward along the movable slot 33. This step allows the limiting blocks 34 to automatically reset after the push of the top block 32 is released, without the need for manual pressing to reset, which improves the convenience of disassembling or adjusting the first metal plate 24 and the second metal plate 25.

[0021] Reference Figures 1-5Two rotating shafts 4 are fixed to the top of the fixed frame 1. Mounting plates 41 are fixed to the side walls of the rotating shafts 4. A counterweight plate 42 is fixed to the top of the mounting plate 41. Handles 43 are fixed to both ends of the mounting plate 41. The rotating shafts 4 fixed to the top of the fixed frame 1 provide a fulcrum for the mounting plate 41, allowing it to rotate freely around the rotating shafts 4. When it is necessary to fix the block 2, manually hold the handles 43 at both ends of the mounting plate 41 and rotate the mounting plate 41 towards one side of the fixed frame 1, so that the mounting plate 41 fits against the top of the fixed frame 1. At this time, the mounting plate 41 will cover the top of multiple placement slots 11. When block 2 is subjected to downward pressure, the counterweight plate 42 on the top of the mounting plate 41 increases the weight of the mounting plate 41 itself, using gravity to enhance the pressure on block 2 below. Pulling the handle 43 in the opposite direction causes the mounting plate 41 to rotate upward around the rotating shaft 4, opening the contact state with the fixed frame 1. At this time, the pressure above block 2 is released, and it can easily slide out of the placement slot 11. This step, through the cooperation of the rotating shaft 4, the mounting plate 41 and the handle 43, achieves the reinforcement of block 2. The design of the counterweight plate 42 uses gravity to enhance the fixing pressure, ensuring the stability of block 2 during the conveying process.

[0022] In summary, when using the conveyor roller of the hot rolling mill disclosed in this application embodiment, firstly, the two fixed frames 1 are fixed in the designated position by the bottom support legs 12 and the mounting pieces 13. Then, the block 2 is slidably installed along the inner wall of the placement groove 11 at the top of the fixed frame 1, so that the block 2 is stably embedded in the placement groove 11. Next, the square shaft 22 is aligned with the inner wall of the bearing 21 on one side of the block 2. By using the insertion and cooperation between the square shaft 22 and the rotor of the bearing 21, the square shaft 22 can rotate flexibly in the bearing 21, thereby driving the rotating column 23 fixed at the end to rotate synchronously. Before the square shaft 22 is engaged, the first metal piece 24 and the second metal piece 25 are slidably sleeved along the outer wall of the rotating column 23. After being adjusted to a suitable position, the two metal pieces are fixed by the fixing mechanism 3. The end of the fixed mechanism 3 is positioned to limit the position of the first metal plate 24 and the second metal plate 25 sleeved on the rotating column 23. First, the square shaft 22 is inserted into the bearing 21 of the block 2. At this time, the square column 31, which slides through the inner wall of the square shaft 22, will first press against the inner wall of the block 2 due to its own protruding structure, and continue to push the square shaft 22 deeper into the bearing 21. The square column 31 slides towards the top block 32 due to the reaction force of the inner wall of the block 2, which drives the top block 32, which is fixed at the end, to move synchronously. Since the top block 32 is arc-shaped and the rotating column 23 has two sets of movable grooves 33 inside, the bottom of the limiting block 34 in the movable groove 33 is inclined. When the top block 32 moves, it will contact the inclined surface of the limiting block 34 and move through the space. The inclined plane guides the two limiting blocks 34 upwards, causing them to extend from the movable groove 33. The extended limiting blocks 34 abut against the ends of the first metal plate 24 and the second metal plate 25. Combined with the stepped structure of the rotating column 23, this achieves axial fixation of the metal plates. The gasket 35 on the outer wall of the limiting block 34 increases the contact area with the metal plates. When the top block 32 in the fixing mechanism 3 pushes the limiting block 34 upwards along the movable groove 33, the receiving groove 341 on the inner wall of the limiting block 34 moves synchronously with it, stretching the elastic rope 332 and causing it to deform. When the two limiting blocks 34 need to be reset, the stretched elastic rope 332 releases its elastic potential energy, generating a contraction force that pulls the limiting blocks 34 downwards along the movable groove 33 to reset. The rotating shaft 4 fixed to the top of the fixed frame 1 provides a fulcrum for the mounting plate 41 to rotate. The mounting plate 41 can rotate freely around the rotating shaft 4. When it is necessary to fix the block 2, manually hold the handles 43 at both ends of the mounting plate 41 and rotate the mounting plate 41 to one side of the fixed frame 1 so that the mounting plate 41 is in contact with the top of the fixed frame 1. At this time, the mounting plate 41 will cover the top of multiple placement slots 11 and apply downward pressure to the block 2. The counterweight plate 42 at the top of the mounting plate 41 can increase the weight of the mounting plate 41 itself and use gravity to increase the pressure on the block 2 below. Pull the handles 43 in the opposite direction to make the mounting plate 41 rotate upward around the rotating shaft 4 and open the contact state with the fixed frame 1. At this time, the pressure above the block 2 is released and it can easily slide out of the placement slot 11.
