Description

Technical Field

[0001] This invention relates to the field of converter support device technology, and in particular to a novel steelmaking converter body support device. Background Technology

[0002] Existing steelmaking converter furnace support devices typically include a fixed base, side plates vertically mounted on both sides of the base, and two rotating shafts horizontally mounted between the two side plates via bearing seats. The furnace body is fixedly connected to the two rotating shafts, and the tilting unit is driven to one or both of the rotating shafts. By driving the rotating shafts to rotate, the furnace body is tilted around its axis, thereby realizing processes such as steel tapping, charging, and slag removal. This structure can ensure the force balance and rotational stability of the furnace body during the tilting process and is a commonly used support form in current converter steelmaking equipment.

[0003] However, the vertical side plates on both sides of the aforementioned support device are usually integrally cast or welded with the base. During manufacturing and assembly, due to factors such as machining errors, welding residual stress, and assembly tolerances, it is difficult to ensure that the center lines of the bearing holes on both side plates used to install the rotating shafts are absolutely coaxial. There may be parallel offset or slight angular deviation. Although they meet the relevant standards when leaving the factory, the steelmaking converter is under harsh conditions of high temperature and heavy load for a long time. The furnace body and side plates are affected by heat radiation and heat conduction, which will produce uneven thermal expansion and thermal deformation. This thermal effect will further aggravate the existing installation deviation, causing the actual rotation axis of the two rotating shafts to be significantly offset or skewed, that is, a serious problem of misalignment. When the converter tilts and rotates, the misaligned rotating shafts will generate periodic additional torque and alternating load in the transmission, aggravating the abnormal wear of the bearing raceway and rolling elements, shortening the bearing service life, and seriously affecting the safe operation and production efficiency of the converter.

[0004] Therefore, how to provide a new type of steelmaking converter body support device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The spline sleeve is movably fitted onto the surface of the spline shaft, and one end of the spline shaft is fixedly connected to the connecting assembly.

[0010] The connecting assembly includes two sets of intermediate rings, which are rotatably fitted onto the surface of the furnace body near the center via fixed bearings.

[0011] The connecting assembly also includes two sets of conical rings. The two sets of conical rings are rotatably sleeved on the corresponding conical surface of the furnace body through conical bearings.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] refer to Figures 1-5 In this embodiment, the furnace body 1 and the base 2 are included. A first side plate 3 is vertically fixedly installed on the top of the base 2 near one side. A first joint bearing 5 is fixedly installed on the inner side of the first side plate 3 near the top. The first side plate 3 is fixedly installed on the inner wall of the first joint bearing 5. A connecting assembly is provided on the surface of the furnace body 1 corresponding to the rotating shaft 6. One end of the rotating shaft 6 is fixedly installed on the connecting assembly. The connecting assembly includes an intermediate ring 24. There are two sets of intermediate rings 24. The two sets of intermediate rings 24 are rotatably sleeved on the surface of the furnace body 1 near the middle through a fixed bearing.

[0023] In specific implementation, the base 2, as the load-bearing foundation of the entire device, is made of high-strength steel and can stably support the weight of the first side plate 3, the second side plate assembly 4, and the furnace body 1, adapting to the high-temperature and heavy-load working conditions of the converter. The first side plate 3 is vertically fixed to one side of the base 2, providing stable support for the rotating shaft 6. The first joint bearing 5 allows the rotating shaft 6 to tilt at a small angle, reserving space for subsequent angle adjustment and avoiding adjustment jamming caused by rigid connection. The two sets of intermediate rings 24 are connected to the furnace body 1 through fixed bearings, realizing the linkage between the furnace body 1 and the rotating shaft 6 and spline shaft 22, ensuring that the furnace body 1 can rotate smoothly on its own, and dispersing the force on the furnace body 1 to avoid local stress concentration.

[0024] A second side plate assembly 4 is fixedly installed at a position symmetrical to the first side plate 3 on the top of the base 2. The second side plate assembly 4 includes a second fixing plate 10, a second adjusting plate 11, and a second vertical rod 12. The second fixing plate 10 is longitudinally fixedly installed on the top of the base 2, and the second vertical rod 12 is fixedly installed on the bottom of the second adjusting plate 11. An insertion hole is opened on the top of the second fixing plate 10 corresponding to the second vertical rod 12, and the bottom end of the second vertical rod 12 extends into the insertion hole. The second side plate assembly 4 also includes guide rods 33. There are two sets of guide rods 33, which are axially symmetrical about the second vertical rod 12. The top of the guide rod 33 is fixedly connected to the bottom of the second adjusting plate 11, and a guide hole is opened on the top of the second fixing plate 10 corresponding to the guide rod 33, and the bottom end of the guide rod 33 extends into the guide hole.

[0025] In specific implementation, the second fixed plate 10 is fixedly connected to the base 2, providing an installation base for the second adjusting plate 11 and the support angle adjustment component 7. The cooperation between the second vertical rod 12 and the insertion hole enables the second adjusting plate 11 to move up and down, thereby adjusting the height of the support angle adjustment component 7. The two sets of guide rods 33 are symmetrically arranged, which can limit the movement direction of the second adjusting plate 11, prevent it from shifting or tilting during the up and down movement, ensure adjustment accuracy, and enhance the stability of the second adjusting plate 11 to prevent it from shaking during the load-bearing process.

[0026] The second side plate assembly 4 is provided with a support angle adjustment assembly 7 for adjusting the furnace body 1 and the rotating shaft 6. The end face of the support angle adjustment assembly 7 is fixedly connected to the surface of the connecting assembly. The support angle adjustment assembly 7 includes a worm gear 14, a first transmission gear 15, a worm 16, a rotating gear 17, a drive gear 18, an adjustment drive motor 19, a second joint bearing 20, a spline sleeve 21, and a spline shaft 22. The worm gear 14 is rotatably mounted on the top of the second fixed plate 10. A gear ring 13 is provided on the surface of the second vertical rod 12 corresponding to the worm gear 14. The first transmission gear 15 is rotatably mounted on the top of the second fixed plate 10, and the inner side of the first transmission gear 15 is fixedly connected to the surface of the worm gear 14. The first transmission gear 15 and the gear ring 13 mesh with each other. The worm 16 is rotatably mounted on the side of the second fixed plate 10 corresponding to the worm gear 14 and meshes with the worm gear 14. The rotating gear 17 is fixedly mounted on the bottom end of the worm 16. The drive gear 18 is fixedly mounted on the adjustment motor 19. At the output shaft end of the adjustable drive motor 19, the drive gear 18 and the rotating gear 17 mesh with each other. The adjustable drive motor 19 is fixedly installed on the side of the second fixed plate 10. The second joint bearing 20 is fixedly installed on the inner side of the second adjustable plate 11. The spline sleeve 21 is fixedly installed on the inner wall of the second joint bearing 20. The spline sleeve 21 is movably sleeved on the surface of the spline shaft 22. One end of the spline shaft 22 is fixedly connected to the connecting assembly. When the adjustable drive motor 19 starts, it drives the drive gear 18 to rotate. The rotation of the drive gear 18 drives the worm gear 16 to rotate through the rotating gear 17. The worm gear 16 drives the worm wheel 14 to rotate. The worm wheel 14 drives the first transmission gear 15 to rotate. The rotation of the first transmission gear 15 drives the second vertical rod 12 to move up and down along the insertion hole through the gear ring 13. Thus, the height of the second adjustable plate 11 is adjusted by the up and down movement of the second vertical rod 12. In turn, the angle deviation of the furnace body 1 is adjusted by the spline shaft 22 and the second joint bearing.

[0027] In practice, the adjustment drive motor 19 provides adjustment power, and the matching reduction gear set can achieve self-locking to prevent position deviation after adjustment; the multi-stage meshing of the drive gear 18 with the rotating gear 17, and the worm 16 with the worm wheel 14 can achieve speed reduction and torque increase, ensuring sufficient adjustment force and improving adjustment accuracy; the first transmission gear 15 meshes with the gear ring 13, converting the rotational motion into the linear motion of the second vertical rod 12, realizing the height adjustment of the second adjustment plate 11; the cooperation between the spline sleeve 21 and the spline shaft 22 allows the spline shaft 22 to tilt slightly and move axially while transmitting power, and the cooperation with the second joint bearing 20 ensures smooth angle adjustment and avoids component jamming.

[0028] The first side plate 3 and the second side plate assembly 4 are provided with a tilting control assembly 8 for tilting the furnace body 1. The tilting control assembly 8 includes a first tilting gear 25, a second tilting gear 26, a tilting control motor 27, and a synchronous shaft 28. The tilting control motor 27 is fixedly installed on the outer side of the first side plate 3, and the synchronous shaft 28 is rotatably installed on the first side plate 3 and the second fixed plate 10. There are two sets of the first tilting gear 25 and the second tilting gear 26. The two sets of the first tilting gear 25 and the second tilting gear 26 are axially symmetrical about the furnace body 1. The two sets of the first tilting gear 25 are fixedly sleeved on the surface of the synchronous shaft 28, and the two sets of the second tilting gear 26 are respectively fixedly sleeved on the surfaces of the rotating shaft 6 and the splined shaft 22. The two sets of the second tilting gear 26 mesh with the two sets of the first tilting gear 25. The tilting control motor 27 is fixedly installed. The side of the first side plate 3 is used to drive the synchronous shaft 28 to rotate. It should be noted that when the furnace body 1 is heated or subjected to heavy loads during use, the first tilting gear 25 and the second tilting gear 26 will mesh more tightly, and the force on the 26 will directly act on the first tilting gear 25. This will greatly affect the normal operation of the two, because there will be a certain gap when the two are assembled. Under normal operation, the first tilting gear 25 is not under load. After the angular deviation occurs, the gap between the first tilting gear 25 and the second tilting gear 26 will shrink until it is gone, causing the first tilting gear 25 to be heavily loaded. At this time, it is necessary to control the support angle adjustment component 7 to control the position of the furnace body 1, the spline shaft 22 and the rotating shaft 6. Here, the second joint bearing 20 and the first joint bearing 5 allow the rotating shaft 6 and the spline shaft 22 to tilt at a certain angle.

[0029] In practice, the tilting control motor 27 provides the tilting torque, and the synchronous shaft 28 ensures that the two sets of first tilting gears 25 rotate synchronously, thereby driving the two sets of second tilting gears 26 to move synchronously, ensuring that the rotating shaft 6 and the spline shaft 22 rotate synchronously, and realizing the smooth tilting of the furnace body 1. The two sets of gears are symmetrically arranged, which can make the furnace body 1 evenly stressed, avoid deviation and shaking during the tilting process, and ensure the stability of processes such as steel tapping and slag dumping. When the furnace body 1 has an angular deviation that causes the gear meshing to be too tight, the support angle adjustment component 7 can adjust it in time to restore the reasonable clearance between the gears, avoid heavy-load wear of the gears, and extend the service life of the gears.

[0030] Example 2 refer to Figures 1-5In this embodiment, the connecting assembly also includes a conical ring 23. There are two sets of conical rings 23. The two sets of conical rings 23 are rotatably sleeved on the surface of the furnace body 1 at the corresponding conical surface through conical bearings. The two sets of conical rings 23 are arranged axially symmetrically with the middle ring 24 as the axis of symmetry. The opposite surfaces of the rotating shaft 6 and the spline shaft 22 are fixedly installed on the surface of the middle ring 24. A connecting shaft for increasing strength is fixedly installed on the surface of the second tilting gear 26 near the outer side. The other end of the connecting shaft is fixedly connected to the surface of the conical ring 23.

[0031] In practice, the conical ring 23 is adapted to the conical surface of the furnace body 1 and connected by a conical bearing, which can enhance the connection stability between the connecting component and the furnace body 1, distribute the weight of the furnace body 1, and avoid excessive local stress on the intermediate ring 24; the connecting shaft connects the second tilting gear 26 to the conical ring 23, which can transmit the tilting torque, while enhancing the installation strength of the second tilting gear 26, preventing it from deforming or breaking during the stress process, and ensuring the stable operation of the tilting control component 8.

[0032] Example 3 refer to Figures 1-5 In this embodiment, the side of the intermediate ring 24 is also provided with a rotating component 9 for driving the furnace body 1 to rotate. The rotating component 9 includes a mounting plate 29, a gear ring 30, a rotary motor 31, and a second transmission gear 32. The mounting plate 29 is fixedly installed on the surface of the intermediate ring 24, the rotary motor 31 is fixedly installed on the inner side of the mounting plate 29, the gear ring 30 is fixedly sleeved on the surface of the furnace body 1 near the bottom end, and the second transmission gear 32 is fixedly installed on the output shaft end of the rotary motor 31. The second transmission gear 32 meshes with the gear ring 30. Here, the rotary motor 31, the tilting control motor 27, and the adjustment drive motor 19 are all equipped with reduction gear sets, which have self-locking capability and anti-inertia capability. These are all existing technologies and will not be described in detail.

[0033] In practice, the mounting plate 29 provides a stable mounting carrier for the rotary motor 31, ensuring that it can still work stably when the furnace body 1 is tilted; the rotary motor 31 meshes with the gear ring 30 through the second transmission gear 32 to transmit rotational power to the furnace body 1, realizing the rotation of the furnace body 1, which meets the needs of uniform mixing of materials in the furnace during the steelmaking process and the need to adjust the position of the discharge port; the self-locking function of the reduction gear set can prevent the furnace body 1 from rotating off course after it stops rotating, and the anti-inertia capability can avoid damage to the components by inertial impact when the motor starts and stops, ensuring the service life of the rotating component 9.

[0034] The working principle of this invention is: In use, first fix the base 2 in the designated position to ensure the overall stability of the device. The furnace body 1 is connected to the rotating shaft 6 and splined shaft 22 through the intermediate ring 24 and conical ring 23. After assembly, it is put into use. After the furnace body 1 has been used for a period of time, it is manually inspected. If a misalignment is detected between the rotating shaft 6 and the splined shaft 22, the adjustment drive motor 19 is started. It drives the drive gear 18 to rotate, which drives the worm gear 16 to rotate through the rotating gear 17. The worm gear 16 drives the worm wheel 14 and the first transmission gear 15 to rotate. The first transmission gear 15 drives the second vertical rod 12 to move up and down along the insertion hole through the gear ring 13. Adjust the height of the second adjustment plate 11, and with the cooperation of the first joint bearing 5, the second joint bearing 20 and the splined sleeve 21 with the splined shaft 22, correct the angle of the furnace body 1 so that the rotating shaft 6 and the splined shaft 22 are coaxial, thereby avoiding the additional torque and component wear caused by misalignment. If it is necessary to tilt the furnace body 1 for steel tapping, During slag removal, the tilting control motor 27 is activated, driving the synchronous shaft 28 and two sets of first tilting gears 25 to rotate. Through meshing with the second tilting gear 26, the rotating shaft 6 and splined shaft 22 are driven to rotate synchronously, thereby driving the furnace body 1 to tilt smoothly. The two sets of gears are symmetrically stressed, ensuring smooth tilting. When the furnace body 1 needs to rotate to mix materials and adjust the discharge port position, the rotary motor 31 is activated, driving the furnace body 1 to rotate around its own axis through the second transmission gear 32 meshing with the gear ring 30, adapting to the steelmaking process requirements. Throughout the process, the guide rod 33 ensures the smooth adjustment of the second adjusting plate 11, and the cone ring 23 enhances the support stability. All components work together, solving the problem of different shafts in existing devices and realizing multi-functional operation of furnace body tilting and rotation. Another unmentioned effect is that precise adjustment can reduce component wear, extend the overall service life of the device, reduce equipment maintenance costs, and adapt to high-temperature and heavy-load steelmaking conditions.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
