[0002] In modern rail production, finishing rolling is performed using a universal mill. The mill's complex roll pattern, comprised of four rolls, allows for simultaneous compression of all cross-section components, resulting in uniform deformation, ensuring both product quality and production efficiency.

[0003] A Chinese patent discloses a device for removing steel stuck on the surface of vertical rollers of a universal rolling mill (authorization announcement number CN219425258U). The device comprises a pressure plate, a scraper, a spring, a bolt, a roll box cover, and vertical rollers. One end of the scraper is the working end, and the other end is the lifting end. The working end of the scraper is close to the vertical rollers.

[0004] Although a scraper is added to the rotation path of the vertical roller, and the scraper is tightly fitted to the vertical roller through the elastic force of the spring, and the self-rotation of the vertical roller during the rolling process is used as the driving force, the steel sticking to the surface of the vertical roller is removed in the next rotation cycle after the steel sticking to the surface of the vertical roller is formed, the position of the scraper is fixed after installation, making it difficult to meet the cleaning needs of vertical rollers of more specifications. In addition, the deformation cycle of the spring is short, and its elastic force will weaken after long-term use, thereby affecting the cleaning effect of the scraper on the vertical roller.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, the present utility model provides a device for removing adhered steel on the surface of the vertical roll of a universal rolling mill, including a vertical roll main body 1, which is fixedly installed on the universal rolling mill. A self-cleaning component is arranged above the vertical roll main body 1. The self-cleaning component includes a lifting frame 2 arranged above the vertical roll main body 1. The lifting frame 2 is a strip-shaped frame structure. Two groups of connecting rods 3 are symmetrically arranged on the outer side of the lifting frame 2. The number of each group of connecting rods 3 is two. The bottom ends of the two groups of connecting rods 3 are fixedly connected with mounting brackets 4. Scrapers 5 are fixedly installed at the bottom ends of the mounting brackets 4. Referring to the attached Figure 2 drawing, the mounting brackets 4 and the scrapers 5 are both arc-shaped structures, and the mounting brackets 4 and the scrapers 5 are fixed by bolts, which improves the convenience of disassembly, installation and replacement of the scrapers 5. The scrapers 5 are in contact with the vertical roll main body 1. When the universal rolling mill runs to drive the vertical roll main body 1 to rotate, the four scrapers 5 are respectively used to scrape horizontally on both sides of the top of the vertical roll main body 1, and the maximum horizontal moving distance of the two scrapers 5 at the relative positions is slightly longer than the diameter of the vertical roll main body 1, which can effectively remove the steel slag adhered to the outer surface of the vertical roll main body 1, and will not affect the normal use of the universal rolling mill during the cleaning process.

[0025] Above the lifting frame 2, there is a mounting plate 9. At the bottom end of the inner cavity of the mounting plate 9, two electric push rods 10 are symmetrically and fixedly installed. The electric push rods 10 are electrically connected to an external power source through an external power cord, and the model power of the two electric push rods 10 is the same. The output ends of the two electric push rods 10 are symmetrically and fixedly connected to two fixing rods 11. The bottom ends of the fixing rods 11 are fixedly connected to the top end of the lifting frame 2. By the synchronous operation of the electric push rods 10, the vertical lifting of the lifting frame 2 and other related self-cleaning components is realized, so as to adjust the distance between the scraper 5 and the main vertical roller body 1, and further meet the cleaning work of main vertical roller bodies 1 of more specifications.

[0026] Two movable blocks 6 are slidably sleeved inside the lifting frame 2. The movable blocks 6 are strip-shaped block structures. Two groups of connecting rods 3 are respectively fixedly connected to one side of the two movable blocks 6. Strip-shaped grooves 7 are opened on both sides of the lifting frame 2. The two groups of connecting rods 3 are respectively slidably inserted and connected inside the two strip-shaped grooves 7. Through the sliding insertion connection between the connecting rods 3 and the strip-shaped grooves 7, the maximum lateral movement distance of the connecting rods 3 is limited.

[0027] Two reciprocating lead screws 8 are symmetrically installed inside the lifting frame 2. The two reciprocating lead screws 8 can rotate inside the lifting frame 2. The two movable blocks 6 are respectively threadedly sleeved outside the two reciprocating lead screws 8. By the threaded connection between the reciprocating lead screws 8 and the movable blocks 6, the transverse reciprocating movement of the movable blocks 6 inside the lifting frame 2 when the reciprocating lead screws 8 rotate is realized, and then the transverse reciprocating cleaning of the self-cleaning component on the main vertical roller body 1 is realized. One end of each of the two reciprocating lead screws 8 is fixedly sleeved with a transmission gear 12. A linkage gear 15 is meshed between the two transmission gears 12. By the meshing between the linkage gear 15 and the two transmission gears 12, when the linkage gear 15 rotates, the two transmission gears 12 rotate in the same speed and in opposite directions, and then the two groups of scrapers 5 reciprocate and scrape horizontally in a staggered manner on the main vertical roller body 1. This method can greatly improve the cleaning effect of the main vertical roller body 1. On one side of the top end of the lifting frame 2, there is an installation groove 13. The installation groove 13 is a T-shaped groove. The inner wall of the installation groove 13 is fixedly installed with a servo motor 14. The servo motor 14 is electrically connected to an external power source through an external power cord. The linkage gear 15 is fixedly sleeved outside the output shaft of the servo motor 14.

[0028] The working principle and process of the present utility model

[0029] During use, when installing and fixing this device on a universal rolling mill through the mounting plate 9, during the use of the universal rolling mill, when it is necessary to clean the main vertical roller body 1, the user synchronously controls the operation of the two electric push rods 10. Under the operation of the two electric push rods 10, the fixing rods 11 and the related structures of the lifting frame 2 move downward synchronously until both groups of scrapers 5 are in contact with the main vertical roller body 1.

[0030] At this time, the two electric push rods 10 are closed, and the operation of the servo motor 14 is controlled to drive the linkage gear 15 to rotate. The rotation of the linkage gear 15 drives the two transmission gears 12 to rotate in the same speed and opposite directions. The rotation of the two transmission gears 12 drives the two reciprocating lead screws 8 to rotate synchronously. The rotation of the two reciprocating lead screws 8 drives the movable blocks 6 to move horizontally back and forth in an alternating manner within the lifting frame 2. The movement of the two movable blocks 6 respectively drives the two connecting rods 3 and the two mounting brackets 4 to move synchronously, and then drives the two groups of scraping plates 5 to scrape horizontally back and forth in an alternating manner on the top of the vertical roller body 1. At the same time, with the self-rotation of the vertical roller body 1, the self-cleaning work on the outer surface of the vertical roller body 1 can be finally realized.
