[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5As shown, in this embodiment, an H-beam roughing mill clamping guide device includes guide roller plates 1, of which there are two. A guide roller 2 is rotatably mounted between the two guide roller plates 1 via a bearing. H-beam slots 3 are provided at both ends of the guide roller 2. Assembled semi-circular rings 4 are installed inside the H-beam slots 3. There are several assembled semi-circular rings 4, with two of each of the same size. These assembled semi-circular rings 4 are nested in layers. A movable seat 5 is slidably mounted inside the top of each guide roller plate 1. A rotating shaft 7 is rotatably mounted between two movable seats 5 via a bearing. Steel brush bristles 8 are provided on the rotating shaft 7. A reduction motor 6 is fixedly mounted on one side of one of the movable seats 5. The output end of the reduction motor 6 is fixedly connected to one end of the rotating shaft 7 via a shaft connector. According to… To meet the conveying requirements of different H-beams, several assembled semi-circular rings 4 of different sizes are installed inside the H-beam slot 3, with two of each size. These semi-circular rings 4 are combined into a circle and fitted inside the H-beam slot 3, forming several mutually fitting rings. This allows for adjustment of the size of the H-beam slot 3 and enables the conveying of H-beams of different sizes. During the conveying process, the geared motor 6 drives the rotating shaft 7 to rotate. The steel brush bristles 8 on the rotating shaft 7 clean the iron filings on the H-beams. When using the steel brush bristles 8 on the rotating shaft 7 to clean the surface of H-beams of different sizes, the height of the movable seat 5 can be adjusted to control the height of the rotating shaft 7 and the steel brush bristles 8, thereby controlling the contact between the steel brush bristles 8 and the surface of the H-beams. This allows for surface cleaning of H-beams of different sizes.

[0023] like Figures 1 to 5 As shown, the first bolt hole 9 is symmetrically opened on one side of the assembled semi-circular ring 4, and the second bolt hole 10 is equidistantly opened at both ends of the guide roller 2. A fixing bolt 11 is installed between the second bolt hole 10 and the first bolt hole 9.

[0024] Assemble the semi-circular ring 4 into a circle and fit it inside the H-shaped steel slot 3 to form several interlocking rings. Then, use the fixing bolt 11 threaded through the first bolt hole 9 and the second bolt hole 10 to fix the assembled semi-circular ring 4 on the outside of the guide roller 2, thus achieving the fixed installation of the assembled semi-circular ring 4 on the guide roller 2.

[0025] like Figures 1 to 5 As shown, the two assembled semicircular rings 4 of the same size are integrally provided with a limiting block 12 and a limiting groove 13 at both ends, and the limiting block 12 and the limiting groove 13 are slidably inserted into each other.

[0026] When assembling two identical semi-circular rings 4 into a circle and fitting them into the H-shaped steel slot 3, the two identical semi-circular rings 4 can be positioned and assembled by inserting the limiting block 12 on one of the assembled semi-circular rings 4 into the limiting groove 13 of the other assembled semi-circular ring 4.

[0027] like Figures 1 to 5 As shown, a limiting rod 14 is symmetrically fixedly installed inside the top end of the guide roller plate 1. Limiting holes 15 are opened at both ends of the movable seat 5. The limiting rod 14 is slidably connected to the limiting hole 15. A screw 16 is rotatably installed in the middle of the top end of the guide roller plate 1 through a bearing. A threaded sleeve 17 is fixedly installed at the top end of the movable seat 5. The bottom end of the screw 16 is threadedly connected to the inside of the threaded sleeve 17.

[0028] By controlling the simultaneous rotation of two screws 16, and through the threaded connection between the screws 16 and the threaded sleeve 17, the movable seat 5 is driven to slide and rise along the two limit rods 14, thereby realizing the height adjustment of the rotating shaft 7 and the steel brush bristles 8.

[0029] like Figures 1 to 5 As shown, a transmission wheel 18 is fixedly installed on the top of the screw 16, and a transmission belt 19 is installed between the two transmission wheels 18.

[0030] When one of the screws 16 is controlled to rotate, the transmission belt 19 drives the two transmission wheels 18 to rotate simultaneously, which can control the two ends of the moving seat 5 to rise and fall steadily and synchronously.

[0031] like Figures 1 to 5 As shown, a driven gear 20 is fixedly mounted on the top of one of the transmission wheels 18, a servo motor 21 is fixedly mounted on the top of the guide roller plate 1 on which the driven gear 20 is mounted, and a driving gear 22 is fixedly mounted on the output end of the servo motor 21. The driving gear 22 is meshed with the driven gear 20.

[0032] By controlling the servo motor 21 to drive the drive gear 22 to rotate, the meshing of the drive gear 22 with the driven gear 20 will drive the control screw 16 to rotate.

[0033] like Figures 1 to 5 As shown, a baffle 23 is fixedly installed between the tops of the two guide roller plates 1.

[0034] When the steel brush bristles 8 on the rotating shaft 7 are used to clean the iron filings on the H-beam, the baffle 23 can block the iron filings cleaned from the H-beam to prevent them from splashing onto the components on the top of the guide roller plate 1.

[0035] This utility model provides a clamping and guiding device for H-beam rough rolling, the specific working principle of which is as follows:

[0036] When the device is in use, according to the conveying requirements of different H-beams, several assembled semi-circular rings 4 of different sizes are installed inside the H-beam slot 3, and there are two assembled semi-circular rings 4 of each size. They are combined into a circle and fitted inside the H-beam slot 3 to form several mutually fitting rings. Then, fixing bolts 11 are threaded through the first bolt hole 9 and the second bolt hole 10 to fix the assembled semi-circular rings 4 on the outside of the guide roller 2, so as to adjust the size of the H-beam slot 3 and realize the conveying of H-beams of different sizes.

[0037] During the conveying of H-beams, the geared motor 6 drives the rotating shaft 7 to rotate, and the steel brush 8 on the rotating shaft 7 cleans the iron filings on the H-beams. The servo motor 21 drives the drive gear 22 to rotate, and the meshing of the drive gear 22 and the driven gear 20 drives one of the screws 16 to rotate. The transmission belt 19 drives the two transmission wheels 18 to rotate the two screws 16 simultaneously. The threaded connection between the screws 16 and the threaded sleeve 17 drives the moving seat 5 to slide and rise along the two limit rods 14, realizing the height adjustment of the rotating shaft 7 and the steel brush 8. This allows for surface cleaning of H-beams of different sizes.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
