Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary positioning structure for sprue installation, and specifically to a positioning device for a long sprue in continuous casting. Background Technology

[0002] Continuous casting is a production process that continuously casts steel into billets with a certain cross-sectional shape and size. It is also one of the main production methods in steel manufacturing today because it is highly efficient and can produce steel of different sizes and shapes as needed, greatly improving the output of steel production.

[0003] The main function of a continuous casting machine is to pour molten steel into the corresponding casting mold, where the molten steel is shaped and cooled. To ensure the safety of pouring the molten steel, a long nozzle needs to be connected to the ladle nozzle, and a submerged entry nozzle needs to be connected to the tundish. This ensures the smooth output of the molten steel. To ensure that the molten steel can be discharged smoothly from the nozzle, the long nozzle needs to be aligned with the ladle nozzle; otherwise, the output of the molten steel will be affected.

[0004] Currently, the connection of the sprue is still mainly done manually, which requires a lot of manpower. Furthermore, the sprue and long sprue cannot be aligned and adjusted in real time during the installation process, resulting in positional deviations after installation. This requires tedious adjustments, and the deviations also affect the discharge of molten steel. Therefore, a positioning device for the long sprue of continuous casting is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a continuous casting long nozzle positioning device to improve the accuracy of nozzle installation, reduce labor costs, and minimize molten steel discharge problems caused by installation deviations.

[0006] This invention provides a continuous casting long nozzle positioning device, including a ladle. A mounting groove is formed on the bottom and one end of the side wall of the ladle. A ladle nozzle is formed through the top of the mounting groove. A mounting frame is provided below the ladle opposite to the mounting groove. A connecting plate is slidably connected within the mounting frame. A connecting groove is formed through the middle of the mounting frame. A connecting platform is provided at the bottom of the mounting frame. A support rod is provided on the top side wall of the connecting platform. Fixed plates are fixedly connected to both ends of the support rod. Four positioning telescopic rods are detachably connected evenly to the outer ring wall of each fixed plate.

[0007] As a preferred technical solution of this utility model, the end of the positioning telescopic rod away from the fixed plate is rotatably connected to a ball bearing and a pressure sensor. The extension length of the positioning telescopic rod is the same as the radius of the ladle nozzle, and the docking groove and the ladle nozzle have the same dimensions.

[0008] As a preferred technical solution of this utility model, a motor is embedded in the top side wall of the connecting platform, the output end of the motor is detachably connected to the bottom side wall of the fixing plate near the connecting platform, and a base is provided below the connecting platform.

[0009] As a preferred technical solution of this utility model, the top side wall of the base is detachably connected to a lifting telescopic rod, the output end of the lifting telescopic rod is detachably connected to the bottom side wall of the connecting platform, the bottom of the base and near the four corners are detachably rotatably connected to a horizontal telescopic rod, the bottom end of the horizontal telescopic rod is detachably rotatably connected to a roller, and a level is connected to the base.

[0010] As a preferred technical solution of this utility model, the mounting frame has a through groove in the middle, and the two opposite side walls of the through groove are provided with side sliding grooves. The connecting plate is located in the through groove, and the two side walls of the connecting plate are fixedly connected with sliders, and the sliders are slidably connected in the side sliding grooves.

[0011] As a preferred technical solution of this utility model, the mounting frame has slots evenly and continuously opened on the side walls near the two sides of the through groove, and studs are inserted into the slots. The slider has a positioning groove on the side wall opposite to the slot, and the stud passes through the slot and is threaded into the positioning groove. A long water nozzle is inserted into the docking groove. The outer wall of the top of the long water nozzle is provided with threaded teeth. The long water nozzle passes through the docking groove and is threaded into the ladle water nozzle. The end of the long water nozzle connected into the ladle water nozzle is at the same level as the bottom side wall of the ladle.

[0012] As can be seen from the above technical solution, the continuous casting long nozzle positioning device provided by this utility model has the following effect: the mounting frame is placed on the connecting platform, and the positioning telescopic rods are extended simultaneously. Because the extended lengths of the four positioning telescopic rods are the same, the docking groove can be ensured to be in the center position. Then, the lifting telescopic rod is activated to insert the top fixing plate into the ladle nozzle, and the corresponding positioning telescopic rod is activated to extend, thereby determining the center point of the ladle nozzle. Because the two fixing plates are connected by the support rod, the center point of the ladle nozzle and the docking groove can be ensured to be at the same point. After the center point is determined, the lifting telescopic rod is activated to push the mounting frame into the mounting groove. Then, screws are used to fix the mounting frame in the mounting groove through the mounting holes at the four corners of the mounting frame. This can free up manpower and avoid misalignment during installation. Attached Figure Description

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] Please refer to the following: Figure 1-3 This utility model discloses a continuous casting long nozzle positioning device, comprising: a ladle 1, an installation groove 2 is provided on the bottom and side wall near one end of the ladle 1, a ladle nozzle 3 is provided through the top of the installation groove 2, an installation frame 4 is provided below the ladle 1 opposite to the installation groove 2, a connecting plate 5 is slidably connected in the installation frame 4, a connecting groove 6 is provided through the middle of the installation frame 4, a connecting platform 8 is provided at the bottom of the installation frame 4, a support rod 9 is provided on the top side wall of the connecting platform 8, a fixing plate 10 is fixedly connected to both ends of the support rod 9, and four positioning telescopic rods 11 are detachably connected evenly to the outer ring wall of each fixing plate 10;

[0021] The end of the positioning telescopic rod 11 away from the fixed plate 10 is rotatably connected to a ball bearing and a pressure sensor. The extension length of the positioning telescopic rod 11 is the same as the radius of the ladle nozzle 3, and the docking groove 6 and the ladle nozzle 3 are the same size.

[0022] The technical effect of this solution is as follows: The mounting frame 4 is placed on the connecting platform 8, and the docking groove 6 is fitted onto the support rod 9. Then, the lifting telescopic rod 12 is activated to lift the connecting platform 8, and the upper fixing plate 10 is inserted into the ladle nozzle 3. The center point of the ladle nozzle 3 is then determined by the extension of the positioning telescopic rod 11, which also adjusts the center point of the docking groove 6 to correspond to the ladle nozzle 3. The connecting platform 8 is then lifted until the mounting frame 4 is pushed into the mounting groove 2. The mounting frame 4 is then fixed in the mounting groove 2 with screws to complete the connection. Subsequently, the long nozzle 7 is threaded through the docking groove 6 and connected to the ladle nozzle 3, thus achieving positioning and installation. This method accurately aligns the long nozzle 7 with the ladle nozzle 3, avoiding installation deviations, and simultaneously frees up manpower and reduces labor costs through mechanical means.

[0023] A motor 15 is embedded in the top side wall of the connecting platform 8. The output end of the motor 15 is detachably connected to the bottom side wall of the fixing plate 10 near the connecting platform 8. A base 13 is provided below the connecting platform 8. A lifting telescopic rod 12 is detachably connected to the top side wall of the base 13. The output end of the lifting telescopic rod 12 is detachably connected to the bottom side wall of the connecting platform 8. A horizontal telescopic rod 14 is detachably and rotatably connected to the bottom of the base 13 and near the four corners. A roller is detachably and rotatably connected to the bottom end of the horizontal telescopic rod 14. A level is connected to the base 13.

[0024] The technical effects of this solution are as follows: the motor 15 drives the support rod 9 to rotate, and the rotation of the positioning telescopic rod 11 increases the accuracy of the center point positioning. The rollers are connected to the bottom of the base 13 via the horizontal telescopic rod 14, which can be moved and adjusted as needed. This works in conjunction with the positioning telescopic rod 11 to ensure the centering effect and efficiency. Because the horizontal telescopic rod 14 can extend and retract, the horizontality of the equipment can be guaranteed even on uneven ground, thus ensuring the centering effect and avoiding the impact of uneven ground on installation.

[0025] A through groove 20 is provided in the middle of the mounting frame 4. Side sliding grooves 16 are provided on the opposite side walls of the through groove 20. The connecting plate 5 is located in the through groove 20, and sliders 17 are fixedly connected to both side walls of the connecting plate 5. The sliders 17 are slidably connected in the side sliding grooves 16. Slots 19 are evenly provided in the side walls of the mounting frame 4 near the two edges of the through groove 20. Studs are inserted into the slots 19. Positioning grooves 18 are provided on the side walls of the sliders 17 opposite to the slots 19. The studs pass through the slots 19 and are threaded into the positioning grooves 18. A long water nozzle 7 is inserted into the docking groove 6. The outer wall of the top of the long water nozzle 7 is provided with threaded teeth. The long water nozzle 7 passes through the docking groove 6 and is threaded into the ladle water nozzle 3. The end of the long water nozzle 7 connected in the ladle water nozzle 3 is at the same level as the bottom side wall of the ladle 1.

[0026] The technical effect of this solution is as follows: because a through groove 20 is provided on the mounting frame 4, and a side slide groove 16 and a slider 17 are also provided, it can ensure that the connecting plate 5 can move within the through groove 20. The position of the docking groove 6 can be adjusted without the mounting frame 4 itself moving. This is suitable for the installation and alignment of some displaced ladle nozzles 3. After adjustment, a stud is used to thread through the slot 19 into the positioning groove 18 to position the connecting plate 5 and prevent the connecting plate 5 from shaking and affecting subsequent alignment and installation.

[0027] The specific operation method of this equipment is as follows: First, place the mounting frame 4 on the connecting platform 8, then activate the lower positioning telescopic rod 11 to support the inner wall of the docking groove 6. This will drive the connecting plate 5 and the mounting frame 4 to move, thereby adjusting the support rod 9 to the center point of the docking groove 6. After the equipment moves to the bottom of the ladle 1 via the rollers, activate the horizontal telescopic rod 14 according to the level. The extension and retraction of the horizontal telescopic rod 14 will adjust the base 13 to a horizontal state. Then, activate the lifting telescopic rod 12 to lift the connecting platform 8 until the top positioning telescopic rod 11 is inserted into the ladle nozzle 3. Then, activate the corresponding positioning telescopic rod 11 to extend. With the extension of the four positioning telescopic rods... The extension of rod 11 is ensured by the pressure sensor to ensure that the extended positioning telescopic rod 11 fits against the inner wall of the ladle nozzle 3, thus determining the center point of the ladle nozzle 3. The support rod 9 ensures that the center points of the ladle nozzle 3 and the docking groove 6 are in the same position. Then, the connecting platform 8 on the platform pushes the mounting frame 4 into the mounting groove 2. After that, the mounting frame 4 is fixed in the mounting groove 2 with screws. Then, the connecting plate 5 is positioned using studs. Finally, the positioning telescopic rod 11 is retracted and then lowered to its original position by the lifting telescopic rod 12. The long nozzle 7 is then threaded into the ladle nozzle 3 to achieve the overall positioning installation.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and not to limit it.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

[0030] These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model, and they should all be covered within the scope of the claims and description of this utility model.
