[0002] Steel structure components mainly include steel roof trusses, steel grid frames, steel brackets, steel trusses, steel columns, steel beams, steel floor slabs, steel supports, steel wall frames, steel purlins, steel platforms, steel ladders, steel railings, scattered steel structures, etc. Bracket beams are brackets that act as beams and are mainly used to support the trusses of the middle roof trusses. Brackets are a type of trusses. Roof trusses are triangular and trapezoidal. They are plane systems, one by one. Grid frames are spatial systems, which are integrated. When in use, they are mostly assembled by steel structural parts. Bracket beam steel structural parts need to be expanded during production. When expanding the holes, employees usually place the required steel structural parts on the expansion device and expand the steel structural parts by manually operating the expansion device.

[0003] When expanding the hole of the bracket beam steel structure, a large amount of iron filings generated by the expansion will accumulate in the hole and adhere to the inner wall of the hole, which is difficult to handle.

[0047] The cleaning component 503 includes a corrugated ring piece 5031 and an oblique blocking rod 5032. An arc-shaped brush 5033 is fixedly connected to the outer side of the corrugated ring piece 5031. A wave-surface circular hole 5034 is opened on the outer side of the corrugated ring piece 5031. The corrugated ring piece 5031 is sleeved on the middle connecting rod 502 and fixedly connected to the middle connecting rod 502. One end of the oblique blocking rod 5032 is fixedly connected to the outer side of the middle connecting rod 502. Four oblique blocking rods 5032 are provided, and the four oblique blocking rods 5032 are evenly distributed on the outer side of the middle connecting rod 502. A plurality of arc-shaped brushes 5033 are provided, and the plurality of arc-shaped brushes 5033 are evenly distributed on the outer side of the corrugated ring piece 5031. A plurality of wave-surface circular holes 5034 are provided, and the plurality of wave-surface circular holes 5034 are evenly distributed on the corrugated ring piece 5031. The outer side of the sheet 5031, when in use, the bracket beam steel structure is placed between the four fixing mechanisms 7 on the processing table 1, and the position on the bracket beam steel structure that needs to be expanded is aligned with the round through hole 8. After the alignment is completed, the bracket beam steel structure is respectively pushed and fixed from both sides by the four fixing mechanisms 7. After the fixation is completed, the motor 4 is started to drive the bottom connecting column 3 to rotate, and the rotation of the connecting column 3 drives the bottom hole cleaning mechanism 5 to rotate, and the rotation of the hole cleaning mechanism 5 drives the bottom drill bit 6 to rotate. When the drill bit 6 rotates, the electric push rod 10 pushes the motor 4 to move downward. When the motor 4 moves downward, it drives the bottom connecting column 3, the hole cleaning mechanism 5 and the drill bit 6 to move downward together, and the drill bit 6 that rotates downward to expand the hole on the surface of the bracket beam steel structure. After the hole expansion is completed, the hole cleaning mechanism 5 continues to move down to the inside of the round hole 8. At this time, the rotating hole cleaning mechanism 5 scrapes and cleans the inner wall of the expanded hole and the round hole 8. The connection column 3 rotates to drive the middle connecting rod 502 at the bottom to rotate. When the middle connecting rod 502 rotates, it drives the outer spiral scraper 501 and the cleaning component 503 to rotate together. When the spiral scraper 501 rotates in the round hole 8 and the expanded hole, the outer side is always in contact with the round hole 8 and the inner wall of the expanded hole. The rotating spiral scraper 501 performs spiral scraping and cleaning on the round hole 8 and the inner wall of the expanded hole. The scraped and cleaned iron filings fall on the spiral scraper 501 and slide down along the spiral path of the spiral scraper 501 and fall on the cleaning component 503 and the inclined circular plate 505. By opening a plurality of The chip-passing circular hole 504 allows iron chips to quickly slide off the spiral scraper 501. The rotation of the middle connecting rod 502 drives the inclined circular plate 505 at the bottom to rotate. When the inclined circular plate 505 rotates, it drives the iron chips falling from the surface to rotate together. The iron chips accumulated on the inclined circular plate 505 slide outwardly through the inclined surface of the inclined circular plate 505 and the centrifugal force. When the inclined circular plate 505 rotates, it drives the outer grinding protrusion 506 to rotate together. The grinding end of the grinding protrusion 506 is always in contact with the inner wall of the circular through hole 8 and the expanded hole. Multiple grinding protrusions 506 fully grind the circular through hole 8 and the inner wall of the expanded hole as the inclined circular plate 505 rotates. When the middle connecting rod 502 rotates, it drives the outer oblique blocking rod 5032 and the corrugated ring piece 5031 to rotate together.As the middle connecting rod 502 rotates, the corrugated ring piece 5031 is gradually extended outward by the centrifugal force. The oblique blocking rod 5032 is tilted above the corrugated ring piece 5031 and blocks and limits it. The corrugated ring piece 5031 extends outward along the oblique surface of the inclined circular plate 505 under the resistance of the oblique blocking rod 5032. When the corrugated ring piece 5031 extends, it slides and scrapes the surface of the inclined circular plate 505. When the corrugated ring piece 5031 extends, it drives the outer arc brush 5033 to move outward together. When the arc brush 5033 moves, it gradually approaches the grinding protrusion 506 and contacts the grinding protrusion 506. The brush 5033 rubs and cleans the surface of the grinding bump 506 and the grinding bump 506 as the wave-shaped ring piece 5031 stretches. When the middle connecting rod 502 stops rotating, the wave-shaped ring piece 5031 loses the centrifugal force and starts to shrink in a wave shape toward the middle connecting rod 502. When the wave-shaped ring piece 5031 shrinks in a wave shape, the iron filings between the wave-shaped ring piece 5031 and the inclined circular plate 505 are pushed. When the iron filings between the wave-shaped ring piece 5031 and the inclined circular plate 505 are pushed, they are continuously accumulated and overflow from the wave-shaped circular hole 5034 to the outside. By opening a plurality of wave-shaped circular holes 5034 on the wave-shaped ring piece 5031, it is convenient for the iron filings to pass through.

[0048] For the second embodiment, please refer to Figure 1-Figure 8The present invention provides a heat dissipation and hole expanding device for processing a bracket beam steel structure: a fixing mechanism 7 comprises a first square plate 701, a threaded rod 702 is penetrated and threadedly connected to one side of the first square plate 701, one end of the threaded rod 702 is rotatably connected to a second square plate 703 through a rotating bolt, a hollow air cushion 704 is fixedly connected to the side of the second square plate 703 away from the threaded rod 702, an exhaust circular hole 705 is provided on the outer side of the hollow air cushion 704, a frosting block 706 is fixedly connected to the side of the hollow air cushion 704 away from the second square plate 703, a curved scraper 707 is fixedly connected to the top of the second square plate 703, a long-hair brush 708 is fixedly connected to the inner side of the curved scraper 707, the bottom of the first square plate 701 is fixedly connected to the top of the processing table 1, and the second square plate 7 The bottom of 03 is slidably connected to the top of the processing table 1, a plurality of exhaust holes 705 are provided, and the plurality of exhaust holes 705 are evenly distributed on the outside of the hollow air cushion 704, a plurality of frosting blocks 706 are provided, and the plurality of frosting blocks 706 are evenly distributed on one side of the hollow air cushion 704, a plurality of curved scrapers 707 are provided, and the plurality of curved scrapers 707 are evenly distributed on the top of the second square plate 703, a plurality of long-hair brushes 708 are provided, and the plurality of long-hair brushes 708 are evenly distributed on the inner side of the curved scraper 707. When in use, the bracket beam steel structure is placed between the four hollow air cushions 704, and the threaded rod 702 is manually rotated to threadably cooperate with the first square plate 701 to spirally move toward the bracket beam steel structure, and the threaded rod 702 drives the bottom when rotating. The restricted second square plate 703 moves toward the direction of the bracket beam steel structure. When the second square plate 703 moves, it drives the curved scraper 707 on the top and the hollow air cushion 704 on one side to move together. When the curved scraper 707 moves, it contacts the side of the bracket beam steel structure first. After the curved scraper 707 contacts the bracket beam steel structure, it is squeezed by the second square plate 703 and slides on the side of the bracket beam steel structure. The curved scraper 707 slides and scrapes the position on the side of the bracket beam steel structure that is about to contact the grinding block 706. When the curved scraper 707 is pushed and slides on the side of the bracket beam steel structure, it gradually bends toward the two sides of the second square plate 703. When the curved scraper 707 bends toward the two sides of the second square plate 703, it drives the long-bristled brush 708 on the inside to move toward the two sides of the second square plate 703. When the long-bristled brush 708 moves sideways, it is in contact with the sanding block 706 at all times and performs friction cleaning on the sanding block 706. After the curved scraper 707 is pushed to both sides of the second square plate 703, the sanding block 706 gradually approaches the side of the bracket beam steel structure and contacts with its side. By arranging multiple sanding blocks 706 on one side of the hollow air cushion 704, the friction contact with the side of the bracket beam steel structure is increased. After the side of the bracket beam steel structure contacts the sanding block 706, the second square plate 703 squeezes the hollow air cushion 704. The hollow air cushion 704 is compressed by the squeezing force, so that the internal air is discharged to the outside through the exhaust circular hole 705. By arranging the hollow air cushion 704 made of elastic material on one side of the second square plate 703, a slight elastic shock-absorbing space is provided for the bracket beam steel structure.

[0049] When the present invention is operated and used, the bracket beam steel structure is placed between the four fixing mechanisms 7 on the processing table 1, and the position on the bracket beam steel structure that needs to be expanded is aligned with the round through hole 8. After the alignment is completed, the bracket beam steel structure is respectively pushed and fixed from both sides by the four fixing mechanisms 7. After the fixation is completed, the motor 4 is started to drive the bottom connecting column 3 to rotate, and the rotation of the connecting column 3 drives the bottom hole cleaning mechanism 5 to rotate, and the rotation of the hole cleaning mechanism 5 drives the bottom drill bit 6 to rotate. When the drill bit 6 rotates, the electric push rod 10 pushes the motor 4 to move downward. When the motor 4 moves downward, it drives the bottom connecting column 3, the hole cleaning mechanism 5 and the drill bit 6 to move downward together, and the drill bit 6 that is rotated downward to expand the hole on the surface of the bracket beam steel structure. After the expansion is completed, After that, the hole cleaning mechanism 5 continues to move down to the inside of the round through hole 8. At this time, the rotating hole cleaning mechanism 5 scrapes and cleans the inner wall of the expanded hole and the round through hole 8. The connection column 3 rotates to drive the middle connecting rod 502 at the bottom to rotate. When the middle connecting rod 502 rotates, it drives the outer spiral scraper 501 and the cleaning component 503 to rotate together. When the spiral scraper 501 rotates in the round through hole 8 and the expanded hole, the outer side is always in contact with the round through hole 8 and the inner wall of the expanded hole. The rotating spiral scraper 501 performs spiral scraping and cleaning on the round through hole 8 and the inner wall of the expanded hole. The scraped and cleaned iron chips fall on the spiral scraper 501 and slide down along the spiral path of the spiral scraper 501 and fall on the cleaning component 503 and the inclined circular plate 505. By opening a plurality of chip-passing circular holes 5 on the spiral scraper 501 04 is convenient for iron filings to quickly slide off the spiral scraper 501. The rotation of the middle connecting rod 502 drives the bottom inclined circular plate 505 to rotate. When the inclined circular plate 505 rotates, it drives the iron filings falling on the surface to rotate together. The iron filings accumulated on the inclined circular plate 505 slide outwardly through the inclined surface of the inclined circular plate 505 and the centrifugal force. When the inclined circular plate 505 rotates, it drives the outer grinding protrusion 506 to rotate together. The grinding end of the grinding protrusion 506 is always in contact with the inner wall of the round through hole 8 and the expanded hole. Multiple grinding protrusions 506 fully grind the round through hole 8 and the inner wall of the expanded hole as the inclined circular plate 505 rotates. When the middle connecting rod 502 rotates, it drives the outer oblique blocking rod 5032 and the corrugated ring piece 5031 to rotate together. The corrugated ring piece 50 As the middle connecting rod 502 rotates, it gradually extends outward under the action of centrifugal force. The oblique blocking rod 5032 is tilted above the wave-shaped ring piece 5031 and blocks and limits it. The wave-shaped ring piece 5031 extends outward along the oblique surface of the inclined circular plate 505 under the resistance of the oblique blocking rod 5032. When the wave-shaped ring piece 5031 extends, it slides and scrapes the surface of the inclined circular plate 505. When the wave-shaped ring piece 5031 extends, it drives the outer arc brush 5033 to move outward together. When the arc brush 5033 moves, it gradually approaches the grinding protrusion 506 and contacts the grinding protrusion 506. As the wave-shaped ring piece 5031 extends, the multiple arc brushes 5033 rub and clean the surface of the grinding protrusion 506 and the grinding protrusion 506.When the middle connecting rod 502 stops rotating, the corrugated ring piece 5031 loses the centrifugal force and starts to shrink in a corrugated shape toward the middle connecting rod 502. When the corrugated ring piece 5031 shrinks in a corrugated shape, the iron filings between the corrugated ring piece 5031 and the inclined circular plate 505 are pushed. When the iron filings between the corrugated ring piece 5031 and the inclined circular plate 505 are pushed, they are continuously accumulated and overflow from the corrugated circular hole 5034 to the outside. By opening a plurality of corrugated circular holes 5034 on the corrugated ring piece 5031, it is convenient for the cleaned iron filings to pass through. After the bracket beam steel structure is placed between the four hollow air cushions 704 , by manually rotating the threaded rod 702 and the first square plate 701 to threadably match and spirally move toward the bracket beam steel structure, the threaded rod 702 drives the second square plate 703 with a bottom limit to move toward the bracket beam steel structure, and the second square plate 703 drives the curved scraper 707 on the top and the hollow air cushion 704 on one side to move together when the second square plate 703 moves. When the curved scraper 707 moves, it contacts the side of the bracket beam steel structure first. After the curved scraper 707 contacts the bracket beam steel structure, it is squeezed by the second square plate 703 and slides on the side of the bracket beam steel structure. The curved scraper 707 slides and scrapes the position on the side of the bracket beam steel structure that is about to contact the grinding block 706. The curved scraper 707 is pushed and gradually bends toward the two sides of the second square plate 703 when sliding on the side of the bracket beam steel structure. When the curved scraper 707 bends toward the two sides of the second square plate 703, it drives the long-haired brush 708 on the inside to move toward the two sides of the second square plate 703. When the long-haired brush 708 moves, it always contacts the grinding block 706 and rubs and cleans the grinding block 706. After the curved scraper 707 is pushed toward the two sides of the second square plate 703, the grinding block 706 6 gradually approaches the side of the bracket beam steel structure and contacts with the side thereof. By setting a plurality of frosting blocks 706 on one side of the hollow air cushion 704 to increase the frictional contact with the side of the bracket beam steel structure, after the side of the bracket beam steel structure contacts the frosting blocks 706, the second square plate 703 squeezes the hollow air cushion 704. The hollow air cushion 704 is compressed by the squeezing force, so that the internal air is discharged to the outside through the exhaust circular hole 705. By setting the hollow air cushion 704 made of elastic material on one side of the second square plate 703, a slight elastic shock-absorbing space is provided for the bracket beam steel structure.
