Description

Technical Field

[0001] The utility model relates to the technical field of cooling beds including rollers or spiral tubes, and particularly relates to a side wheel of a cooling bed skirt plate which is convenient to replace. Background Art

[0002] In a bar production line, a cooling bed skirt plate is required. The steel rolled out from the finished rolling mill is cut into a certain length by a flying shear and conveyed to the cooling bed skirt plate by an input roller table according to set speed parameters. The skirt plate then brakes and unloads the bars into the cooling bed straightening plate to prepare for straightening and cooling the bars on the cooling bed. The Chinese utility model patent with the authorization announcement number "CN208213943U" discloses a side wheel of a cooling bed skirt plate which is anti-jamming and convenient to replace. The side wheel of the rolling steel cooling bed skirt plate of the present utility model includes a pin shaft, a spacer sleeve, a high-temperature resistant bearing and a side wheel which are assembled in sequence. The spacer sleeve is in clearance fit with the pin shaft, the spacer sleeve is in transitional fit with the high-temperature resistant bearing, and the high-temperature resistant bearing has a large clearance and does not use lubricating grease to prevent the grease from carbonizing and jamming the bearing due to high temperature. When the bearing jams, the shaft and the spacer sleeve are in clearance fit, and the side wheel can also be prevented from jamming and not rotating within a short time, and the problem that the pin shaft and the inner ring of the high-temperature resistant bearing are jammed and difficult to disassemble can be avoided.

[0003] During the use of the above technical solution, although the problem that the pin shaft and the inner ring of the high-temperature resistant bearing are jammed and difficult to disassemble can be avoided, when disassembling the pin shaft, it is necessary to first screw the disassembly tool into the threaded hole, and then pull out the pin shaft to disassemble the side wheel. Furthermore, when disassembling the pin shaft, it is also necessary to first find the disassembly tool for disassembly, making it inconvenient to quickly pull out the pin shaft when replacing the side wheel, and the extraction of the pin shaft when replacing the side wheel is not convenient enough. Therefore, we propose a side wheel of a cooling bed skirt plate which is convenient to replace. Content of the Utility Model

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a cold bed skirt plate side wheel that is easy to replace, including:

[0027] Side wheel 1, two high-temperature resistant bearings 9 are installed inside the side wheel 1, a mounting cylinder 3 is installed inside the two high-temperature resistant bearings 9, and a pin shaft 2 is installed inside the mounting cylinder 3;

[0028] The disassembly pin pulling structure is located on the pin shaft 2;

[0029] The disassembly pin pulling structure includes a mounting seat 5 and a rotating plate 8. The mounting seat 5 is fixedly connected to the top of the pin shaft 2. A receiving groove 7 is formed in the top of the mounting seat 5. The rotating plate 8 is rotatably connected to the inside of the receiving groove 7. A square groove 15 is formed in one side of the rotating plate 8. A first sliding groove 13 is formed in the inside of the mounting seat 5. Second sliding grooves 16 are formed on both sides of the rotating plate 8.

[0030] The disassembly pin pulling structure further includes a square sliding rod 6, a first spring 12 and a first sliding plate 11. The square sliding rod 6 is slidably connected to the inside of the first sliding groove 13. The first sliding plate 11 is fixedly sleeved on the outer surface of the square sliding rod 6. One end of the square sliding rod 6 slidably extends into the receiving groove 7 and is inserted into the square groove 15. The end of the square sliding rod 6 away from the rotating plate 8 slidably extends to the outside of the mounting seat 5. The first spring 12 is sleeved on the outer surface of the square sliding rod 6. One end of the first spring 12 is fixedly connected to the first sliding plate 11. The end of the first spring 12 away from the first sliding plate 11 is fixedly connected to the inner wall of the first sliding groove 13.

[0031] Second sliding plates 14 are slidably connected to the inside of the two second sliding grooves 16. Telescopic rods 10 are fixedly connected to the opposite surfaces of the two second sliding plates 14. Second springs 17 are fixedly connected to the opposite surfaces of the two second sliding plates 14. The ends of the two second springs 17 away from the corresponding second sliding plates 14 are fixedly connected to the inner walls of the corresponding second sliding grooves 16. A sealing ring 4 is installed on the top of the side wheel 1. The sealing ring 4 is located on the outer surface of the mounting cylinder 3.

[0032] Further, when using the device, the operator pulls the square sliding rod 6. The movement of the square sliding rod 6 drives the first sliding plate 11 to compress the first spring 12. When the square sliding rod 6 disengages from the square groove 15, the operator rotates the rotating plate 8 by 90 degrees. Subsequently, the operator releases the square sliding rod 6, so that the square sliding rod 6 will be reset under the support of the first spring 12, and then it is convenient to be inserted into the square groove 15, thereby being able to fix the rotating plate 8. When the rotating plate 8 rotates, the two telescopic rods 10 will pop out from the corresponding second sliding grooves 16 under the support of the corresponding second springs 17, so that it is convenient for the operator to pull out the pin shaft 2 through the rotating plate 8.

[0033] Through the cooperation of the rotating plate 8, the square sliding rod 6, the first spring 12, the second spring 17 and the telescopic rods 10, the square sliding rod 6 can limit and fix the rotated rotating plate 8, and the two telescopic rods 10 cooperate with the rotating plate 8 to pull out the pin shaft 2, so that there is no need to find a disassembly tool to disassemble the side wheel 1, further improving the convenience of replacing the side wheel.

[0034] Working principle: By the operator pulling the square slide bar 6, the movement of the square slide bar 6 drives the first sliding plate 11 to compress the first spring 12. When the square slide bar 6 disengages from the square groove 15, the operator rotates the rotating plate 8 by 90 degrees. Subsequently, the operator releases the square slide bar 6, enabling the square slide bar 6 to reset under the support of the first spring 12, thereby facilitating its insertion into the square groove 15, and thus being able to fix the rotating plate 8. When the rotating plate 8 rotates, the two telescopic rods 10 will pop out from the corresponding second sliding grooves 16 under the support of the corresponding second springs 17, thereby facilitating the operator to pull out the pin shaft 2 through the rotating plate 8.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present utility model.
