[0002] Continuous casting billets are products obtained by casting molten steel produced in a steelmaking furnace through a continuous casting machine. The application fields of continuous casting billets are becoming increasingly wide, and both domestically and internationally, continuous casting billet parts are used in mechanical engineering equipment.
[0003] During the continuous casting billet operation, the billet is conveyed by roller conveyor. Since the entire operation is continuous, in order to ensure the rolling of the billet, the billet is cut to a fixed length. Usually, a flame cutting device is used to cut the billet to form a certain length dimension.
[0004] After a section of billet is cut, on the one hand, due to the large gap between the two roller conveyors, the head of the continuously cast billet tilts downward due to gravity, which is not conducive to adjusting the cut billet onto the normally operating roller conveyor. On the other hand, if the billet deviates during the conveying process on the roller conveyor, it is inconvenient to correct it.
[0005] Therefore, the present invention provides a continuous casting billet guiding device. Summary of the Invention

Detailed Implementation
[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0031] Combination Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of the present invention, a continuous casting billet guiding device includes a roller conveyor 1 and a guide platform 3. The guide platform 3 is located on one side of the middle of the roller conveyor 1. A support plate 4 is fixedly connected to the end side wall of the guide platform 3. Two guide plates 5 are symmetrically fixedly connected to the support plate 4. A first straightening mechanism and a second straightening mechanism are provided on the guide plate 5. The first straightening mechanism is used to straighten the billet after cutting, and the second straightening mechanism is used to straighten the billet during the conveying process. Both the guide platform 3 and the guide plate 5 are provided with a cleaning mechanism, which is used to clean the slag on the surface of the billet. During operation, during the processing of the continuous casting billet 2, the continuous casting billet is conveyed through the continuous casting billet 2. After the continuous casting billet 2 is flame-cut, the cut billet... The end of the billet is conveyed to the guide plate 5 via roller conveyor 1. The first straightening mechanism straightens it to avoid deviation in its conveying direction. After the billet is straightened by the first straightening mechanism, it comes into contact with the guide table 3. Guided by the guide table 3, the bottom surface of the head of the continuous casting billet 2 is at the same height as the roller conveyor 1, which helps to adjust the cut billet to the normal operating roller conveyor. If the billet deviates during the normal operation of the roller conveyor, the second straightening mechanism straightens it to facilitate the smooth conveying of the billet on the normal operating roller conveyor. During the process of the cut billet passing through the guide table 3 and the guide plate 5, the cleaning mechanism cleans the slag on its surface, which helps to reduce the impact of slag on the subsequent heating and rolling of the continuous casting billet.
[0032] Combination Figure 3 and Figure 4As shown, the first straightening mechanism includes a slide groove 9 and a fixed frame 12. The slide groove 9 is located on the guide plate 5 at one end away from the guide table 3. A first straightening plate 10 is slidably connected inside the slide groove 9. The fixed frame 12 is fixedly connected to the side wall of the guide plate 5. A cylinder 13 is fixedly connected to the fixed frame 12. The telescopic rod of the cylinder 13 passes through the end of the fixed frame 12 and is fixedly connected to the first straightening plate 10. During operation, after the continuous casting billet 2 is flame-cut, the end of the cut billet is conveyed to the guide plate 5 through the roller conveyor 1. At the same time, two cylinders 13 are activated, and the telescopic rods of the two cylinders 13 push the corresponding first straightening plates 10. The two first straightening plates 10 correct the position of the cut billet, which helps to prevent the end of the billet from tilting and hitting the guide plate 5, affecting the conveying of the billet.
[0033] Combination Figure 2 , Figure 3 and Figure 6 As shown, the cleaning mechanism includes four mounting plates 6, which are respectively installed at the ends of the guide table 3, the ends of the two guide plates 5, and between the two guide plates 5. Each of the four mounting plates 6 has an insertion groove, and a scraper 7 is slidably connected in each insertion groove. Multiple sets of springs 8 are fixedly connected to the end of the scraper 7 away from the continuous casting billet 2. The ends of the multiple sets of springs 8 away from the scraper 7 are fixedly connected to the inner wall of the insertion groove. A trigger assembly is provided on the mounting plate 6 at the ends of the two guide plates 5. The trigger assembly is used to control the start of the second straightening mechanism. During operation, as the cut continuous casting billet 2 passes through the guide plates 5, the two scrapers 7 at the ends of the guide plates 5 clean the slag skin on the side wall of the continuous casting billet 2, the scraper 7 between the two guide plates 5 cleans the slag skin on the top of the continuous casting billet 2, and the scraper 7 at the end of the guide table 3 cleans the slag skin on the bottom of the continuous casting billet 2. The cooperation of the four scrapers 7 is beneficial to cleaning the slag skin on the surface of the scraper 7, which helps to avoid the influence of the slag skin on the subsequent heating and rolling of the billet.
[0034] Combination Figure 3 , Figure 4 As shown, the second straightening mechanism includes two slid grooves, which are respectively opened at one end of the guide plate 5 near the first slid groove 9. A second straightening plate 14 is slidably connected in the second slid groove. A pushing component is provided at the end of the second straightening plate 14 away from the guide plate 5. The pushing component is used to push the second straightening plate 14 to move. During operation, after the continuous casting billet 2 has passed the first straightening plate 10 for the first time, if the continuous casting billet 2 deviates during the conveying process, the trigger component is activated, the cylinder 13 is activated, and the telescopic rod of the cylinder 13 pulls the first straightening plate 10 backward. During the process of the cylinder 13 pulling the first straightening plate 10 backward, the pushing component pushes the second straightening plate 14 to move towards the guide plate 5 to correct the position of the continuous casting billet 2, which is conducive to maintaining the continuous and smooth conveying of the continuous casting billet 2.
[0035] Combination Figure 3 , Figure 4 As shown, the pushing assembly includes a first toothed plate 15 and a second toothed plate 16. The first toothed plate 15 is fixedly connected to the side wall of the second straightening plate 14, and the second toothed plate 16 is fixedly connected to the side wall of the first straightening plate 10. A horizontal plate is fixedly connected to the side wall of the guide plate 5, and a gear 17 is rotatably connected to the horizontal plate. The gear 17 meshes with both the first toothed plate 15 and the second toothed plate 16.
[0036] During operation, after the continuous casting billet 2 is first corrected by the first straightening plate 10, if a deviation occurs during the conveying process on the continuous casting billet 2, the trigger assembly is activated, and the telescopic rod of the cylinder 13 pulls the first straightening plate 10 backward. During the process of the cylinder 13 pulling the first straightening plate 10 backward, the toothed plate 16 drives the gear 17 to rotate clockwise. The clockwise rotation of the gear 17 drives the toothed plate 15 to push the second straightening plate 14 to move, which is beneficial for the position correction of the continuous casting billet 2 and for the smooth conveying of the continuous casting billet 2 on the roller table 1.
[0037] Combination Figure 6 As shown, the triggering assembly includes a second support frame 27 and a push rod 29. The second support frame 27 is fixedly connected to the side wall of the mounting plate 6, and a pressure sensor 28 is fixedly connected to the second support frame 27. The push rod 29 is slidably connected to the mounting plate 6, and one end of the push rod 29 is fixedly connected to the scraper 7 away from the second support frame 27. During operation, during the conveying of the continuous casting billet 2, the scraper 7 cleans the side wall of the continuous casting billet 2. When the continuous casting billet 2 deviates, it will squeeze the scraper 7. When the continuous casting billet 2 exits... When the offset is large, the squeezing amount of scraper 7 will also increase. When the offset of continuous casting billet 2 is large, scraper 7 drives top rod 29 to contact pressure sensor 28 and squeeze pressure sensor 28. After the pressure value of pressure sensor 28 exceeds the preset value, cylinder 13 is started and the telescopic rod of cylinder 13 is retracted. Through toothed plate 2 16, gear 17 and toothed plate 15, the second straightening plate 14 is moved towards continuous casting billet 2 to straighten continuous casting billet 2, which is conducive to the continuous and stable transmission of continuous casting billet 2.
[0038] Combination Figure 3 and Figure 5As shown, two support frames 19 are symmetrically fixedly connected to the two side walls of the guide table 3 near the roller conveyor 1. Each support frame 19 has a groove 20 on its top, and a lifting seat 21 is slidably connected within each groove 20. A pressure roller 22 is rotatably connected between the two lifting seats 21. Two springs 30 are fixedly connected to the bottom of the lifting seat 21, with the ends of the springs 30 away from the lifting seat 21 fixedly connected to the bottom of the groove 20. A cable assembly is provided at the bottom of the lifting seat 21, used to pull the lifting seat 21 downwards. During operation, the toothed plate 15 drives the second straightening plate 14 to... As the continuous casting billet 2 moves and is straightened, the cable assembly pulls the lifting seat 21 downward, causing the lifting seat 21 to drive the pressure roller 22 to descend. This causes the pressure roller 22 to press down on the continuous casting billet 2, which helps to increase the friction between the continuous casting billet 2 and the roller table 1. This helps to prevent the continuous casting billet 2 from contacting the continuous casting billet 2 during the second straightening plate 14's position straightening process, thus preventing the continuous casting billet 2 from slipping on the roller table 1. After the second straightening plate 14 completes the position straightening of the continuous casting billet 2, during the second straightening plate 14's reset process, the spring 2 30 pushes the lifting seat 21 back to its initial position.
[0039] Combination Figure 3 , Figure 4 and Figure 5 As shown, the cable assembly includes a take-up reel 18, which is fixedly connected to the top of the gear 17. A pull rope 23 is wound on the take-up reel 18. The end of the pull rope 23 away from the take-up reel 18 passes through the support frame 19 and then rises from the bottom of the slide chute 20 and is fixedly connected to the bottom of the lifting seat 21. During operation, the gear 17 drives the take-up reel 18 to rotate as the gear plate 15 moves the second straightening plate 14 toward the continuous casting billet 2 to straighten the billet 2. The take-up reel 18 winds up the pull rope 23, causing the pull rope 23 to pull down the lifting seat 21. This causes the lifting seat 21 to drive the pressure roller 22 to descend, which in turn causes the pressure roller 22 to press down on the continuous casting billet 2. This helps to increase the friction between the continuous casting billet 2 and the roller table 1 and prevent slippage.
[0040] Combination Figure 3 and Figure 5As shown, two limiting frames 24 are symmetrically fixedly connected to the side wall of the guide table 3. The pulling rope 23 passes through the top of the limiting frame 24. A pull ring 25 is slidably connected to the limiting frame 24. A U-shaped groove is opened on the top of the limiting frame 24. The pull ring 25 is placed in the U-shaped groove of the limiting frame 24. A counterweight 26 is hung on the pull ring 25. During operation, when the first straightening plate 10 performs the first position correction on the continuous casting billet 2, the gear 17 drives the winding reel 18 to rotate. During this process, the rope may loosen at the winding reel 18. The counterweight 26 helps to pull down the pulling rope 23 when the rope loosens at the winding reel 18, so that the pulling rope 23 is always kept taut. This helps to prevent the winding reel 18 from becoming loose and getting tangled with the gear 17 and the gear plate 15.
[0041] Combination Figure 4 and Figure 7 As shown, both the first straightening plate 10 and the second straightening plate 14 are provided with mounting grooves, and rollers 11 are rotatably connected in the mounting grooves. During operation, the setting of rollers 11 is beneficial to the first straightening plate 10 and the second straightening plate 14 in the process of correcting the position of the continuous casting billet 2, reducing friction with the continuous casting billet 2, and facilitating the smooth transmission of the continuous casting billet 2.
[0042] Working principle: During the processing of the continuously cast billet 2, the billet is conveyed through the billet 2. After the billet 2 is flame-cut, the cut end of the billet is conveyed to the guide plate 5 via the roller conveyor 1. At the same time, two cylinders 13 are activated, and the extension rods of the two cylinders 13 push the corresponding first straightening plate 10. The two first straightening plates 10 correct the position of the cut billet, which helps to prevent the end of the billet from tilting and hitting the guide plate 5, thus affecting the conveying of the billet.
[0043] After the cut billet is straightened, it comes into contact with the guide table 3. Guided by the guide table 3, the bottom surface of the head of the continuous casting billet 2 is at the same height as the roller table 1, which facilitates the adjustment of the cut billet to the roller table for normal operation.
[0044] During the billet conveying process, the two scrapers 7 at the ends of the guide plate 5 clean the slag skin on the side wall of the continuous casting billet 2, the scraper 7 between the two guide plates 5 cleans the slag skin on the top of the continuous casting billet 2, and the scraper 7 at the ends of the guide table 3 cleans the slag skin on the bottom of the continuous casting billet 2. The cooperation of the four scrapers 7 is conducive to cleaning the slag skin on the surface of the scraper 7, and helps to avoid the impact of the slag skin on the subsequent heating and rolling of the billet.
[0045] During the conveying of the continuous casting billet 2, the scraper 7 cleans the side wall of the continuous casting billet 2. When the continuous casting billet 2 deviates, it will squeeze the scraper 7. When the deviation of the continuous casting billet 2 is large, the squeezing amount of the scraper 7 will also increase. When the deviation of the continuous casting billet 2 is large, the scraper 7 drives the push rod 29 to contact the pressure sensor 28 and squeeze the pressure sensor 28. After the pressure value of the pressure sensor 28 exceeds the preset value, the cylinder 13 is started, and the telescopic rod of the cylinder 13 is retracted. Through the toothed plate 16, gear 17 and toothed plate 15, the second straightening plate 14 is moved towards the continuous casting billet 2 to straighten the continuous casting billet 2, which is conducive to the continuous and stable conveying of the continuous casting billet 2.
[0046] During the process of the toothed plate 15 moving the second straightening plate 14 toward the continuous casting billet 2 to straighten the continuous casting billet 2, the gear 17 drives the winding reel 18 to rotate. The winding reel 18 winds up the traction rope 23, causing the traction rope 23 to pull down the lifting seat 21, which in turn causes the lifting seat 21 to drive the pressure roller 22 to descend, so that the pressure roller 22 presses down on the continuous casting billet 2, which helps to increase the friction between the continuous casting billet 2 and the roller table 1 and avoid slippage.
