Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0027] Figure 1 This is a schematic diagram of the structure of the steelmaking converter hanging device in an embodiment of the present invention.

[0028] like Figure 1 As shown, the steelmaking converter hanging device provided by the present invention includes a converter unit 10, a tilting mechanism 20, a tilting unit 30, and a clutch unit 40.

[0029] The converter unit 10 includes a base plate 11, a support plate 12, and a converter 13. One end of the support plate 12 is disposed on the base plate 11 and located on both sides of the converter 13. The converter 13 is movably disposed on the support plate 12, and the tilting mechanism 20 is disposed on one side of the converter 13.

[0030] The converter 13 is provided with a first rotating shaft 14 and a second rotating shaft 15 on both sides. The first rotating shaft 14 is movably mounted on a support plate 12 on one side of the converter 13, and the second rotating shaft 15 is movably mounted on a support plate 12 on the other side of the converter 13.

[0031] Figure 2 This is a schematic diagram of the clutch unit in an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of the rear cover in an embodiment of the present invention.

[0032] like Figure 2 and Figure 3 As shown, one side of the clutch unit 40 is connected to the converter 13, and the other side of the clutch unit 40 is connected to the tilting motor 20. The clutch unit 40 includes a bushing 41, a front cover 42, a rear cover 43, a ratchet 44, a ratchet locking assembly 45, and a clutch cylinder 46. The bushing 41 is sleeved on the first rotating shaft 14 and is connected to the first rotating shaft 14 by a key. The bushing 41 is connected to the front cover 42, and the rear cover 43 is connected to the front cover 42 by bolts. A cavity 431 is opened on the side of the rear cover 43 near the front cover 42. The ratchet 44 is disposed in the cavity 431. The tilting shaft 21 of the tilting motor 20 is connected to the ratchet 44 by a key, and the tilting motor 20 can drive the ratchet 44 to rotate in the cavity 431.

[0033] A ratchet locking assembly 45 is disposed within a cavity 431. The cavity 431 has a sliding groove 432. The ratchet locking assembly 45 includes a locking rod 451 and a drive rod 452. The locking rod 451 has a locking groove 453. One end of the locking rod 451 abuts against the sliding groove 432, and the other end abuts against the ratchet 44. The end of the drive rod 452 is movably disposed within the locking groove 453, and the drive rod 452 has a connecting protrusion 454. The drive rod 452 can drive the locking rod 451 to move, causing the end of the locking rod 451 near the ratchet 44 to abut against or move away from the ratchet 44. When the end of the locking rod 451 near the ratchet 44 abuts against the ratchet 44, the ratchet 44 can drive the rear end cover 43 to rotate via the ratchet locking assembly 45, thereby driving the front end cover 42 and the first rotating shaft 14 to rotate, thus causing the converter 13 to rotate.

[0034] The front cover 42 has a mounting groove 421, and the clutch cylinder 46 is disposed in the mounting groove 421 of the front cover 42 and connected to the ratchet locking assembly 45. The clutch cylinder 46 includes a clutch cylinder body 461 and a clutch piston rod 462. The clutch cylinder body 461 is disposed in the mounting groove 421, and one end of the clutch piston rod 462 is movably disposed in the clutch cylinder body 461. The connecting protrusion 454 on the drive rod 452 passes through the mounting groove 421 and is connected to the other end of the clutch piston rod 462. The clutch cylinder 46 is a hydraulic cylinder that can drive the drive rod 452 to move. When the tilting machine 20 is working normally, the clutch cylinder 46 is in the extended state. The drive rod 452 drives the end of the locking rod 451 near the ratchet 44 to abut against the ratchet 44, thereby ensuring that the tilting machine 20 drives the converter 20 to rotate under normal working conditions. When there is a sudden power failure or the tilting machine 20 is in a faulty state, the clutch cylinder 46 retracts. The drive rod 452 drives the end of the locking rod 451 near the ratchet 44 away from the ratchet 44, thereby disconnecting the ratchet 44 from the rear end cover 43.

[0035] Figure 4 This is a schematic diagram of the connection between the flipping unit and the converter in an embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of the flipping unit in an embodiment of the present invention.

[0036] like Figure 4 and Figure 5 As shown, the tilting unit 30 is located on the other side of the converter 13 away from the tilting machine 20 and is connected to the converter 13. The tilting unit 30 includes a tilting block 31 and a tilting cylinder 32. The tilting block 31 is rotatably mounted on the second rotating shaft 15. The tilting block 31 is provided with a tilting protrusion 33. The tilting cylinder 32 is a hydraulic cylinder. The tilting cylinder 32 includes a fixing block 321, a tilting cylinder body 322 and a tilting piston rod 323. The fixing block 321 is mounted on the base plate 11. The tilting cylinder body 322 is rotatably connected to the fixing block 321 by a hinge. One end of the tilting piston rod 323 is telescopically mounted inside the tilting cylinder body 322, and the other end of the tilting piston rod 323 is rotatably connected to the tilting protrusion 33 by a hinge. There are two flip protrusions 33, which are respectively set on both sides of the flip block 31. Two flip cylinders 32 are respectively located on both sides of the flip block 31. The flip piston rods 323 of the two flip levers 32 are respectively connected to the two flip protrusions 33, thereby enhancing the reliability of the structure. The two flip cylinders 32 and the flip block 31 form a linkage structure. The two flip cylinders 32 can drive the flip block 31 to rotate on the second rotating shaft 15.

[0037] Figure 6 This is a cross-sectional view of the protection unit in an embodiment of the present invention; Figure 7 This is a schematic diagram of the sleeve structure in an embodiment of the present invention.

[0038] like Figure 6 and Figure 7 As shown, the steelmaking converter hanging device provided by the present invention also includes a protective unit 50. The protective unit 50 includes a housing 51, a sleeve 52, a synchronization ring assembly 53, and a protective drive cylinder 54. The housing 51 is connected to the tilting block 31. The sleeve 52 is slidably sleeved on the second rotating shaft 15. The synchronization ring assembly 53 is sleeved on the second rotating shaft 15. The housing 51 is also provided with a connecting hole 511. The sleeve 52 is provided with a sleeve protrusion 521. The sleeve protrusion 521 passes through the connecting hole 511 and connects to the protective drive cylinder 54.

[0039] The synchronization ring assembly 53 includes a first synchronization ring 531 and a second synchronization ring 532. The first synchronization ring 531 is fixedly connected to the second rotating shaft 15 by a key connection, and the second synchronization ring 532 is fixedly connected to the second rotating shaft 15 by a key connection. The first synchronization ring 531 is provided with a first synchronization tooth 533, and the second synchronization ring 532 is provided with a second synchronization tooth 534 that is adapted to the first synchronization tooth 533. The inner wall of the sleeve 52 is provided with a sleeve groove 522, and the sleeve groove is provided with gear teeth 523 that are adapted to the first synchronization tooth 533 and the second synchronization tooth 534.

[0040] The protective drive cylinder 54 is an electric cylinder, comprising a protective drive cylinder body 541 and a protective drive piston rod 542. The protective drive cylinder body 541 is mounted on the housing 51. One end of the protective drive piston rod 542 is movably mounted within the protective drive cylinder body 541, and the other end passes through the connecting hole 511 and connects to the sleeve protrusion 521. The protective drive cylinder 54 can drive the sleeve 52 to slide on the second rotating shaft 15, causing the gear teeth 523 to mesh with the first synchronous gear 533 and the second synchronous gear 534, resulting in a firm connection and enhanced structural reliability. Alternatively, it can cause the gear teeth 523 to move away from the first synchronous gear 533 and the second synchronous gear 534. The sleeve 52 is equipped with a buffer spring 524, which is located within the sleeve groove 522. This buffer spring can cushion the sliding of the sleeve 52, preventing the gear teeth 523 from colliding with the first synchronous gear 533 and the second synchronous gear 534, thus preventing damage and improving the reliability of the equipment.

[0041] When the tilting motor 20 is working normally, the protective drive cylinder 54 is retracted, the sleeve 52 moves away from the synchronization ring assembly 53, and the gear teeth 523 move away from the first synchronization tooth 533 and the second synchronization tooth 534. The tilting motor 20 drives the converter 13 to rotate, and the second rotating shaft 15 also rotates on the support plate 12. The synchronization ring assembly 53 rotates with the second rotating shaft 15. When there is a sudden power failure or the tilting motor 20 is in a faulty state, the protective drive cylinder 54 extends, causing the sleeve 52 to slide on the second rotating shaft 15 and approach the synchronization ring assembly 53. This allows the gear teeth 523 to mesh with the first synchronization tooth 533 and the second synchronization tooth 534, connecting the second rotating shaft 15 to the sleeve 52. The sleeve 52 is connected to the protective drive cylinder 54 on the housing 51 through the sleeve protrusion 521, thereby connecting the second rotating shaft 15 to the housing 51. The housing 51 is connected to the tilting block 31, thus connecting the second rotating shaft 15 to the tilting block 31. This avoids the problem of the converter 13 losing its drive due to a sudden power failure or a fault in the tilting motor 20.

[0042] When the steelmaking converter hanging device provided by this invention is used for production, under normal working conditions of the tilting motor 20, the clutch cylinder 46 is in the extended state. The drive rod 452 drives the locking rod 451 to abut against the ratchet 44, and the tilting motor 20 can drive the converter 13 to rotate for production. During this process, the protective drive cylinder 54 is retracted, the sleeve 52 is away from the synchronous ring assembly 53, the gear teeth 523 are away from the first synchronous teeth 533 and the second synchronous teeth 534, and the second rotating shaft 15 also rotates on the support plate 12. The tilting unit 30 and the protective unit 50 do not interfere with the rotation of the converter 13, thus improving the reliability of the equipment. When there is a sudden power failure or the tilting motor 20 is in a faulty state, the clutch cylinder 46 retracts, and the drive rod 452 drives the locking mechanism. The end of the lever 451 near the ratchet 44 moves away from the ratchet 44, thereby disconnecting the ratchet 44 from the rear end cover 43. The connection between the tilting motor 20 and the converter 13 is disconnected, and the protective drive cylinder 54 extends, causing the sleeve 52 to slide on the second rotating shaft 15 and approach the synchronization ring assembly 53. This allows the gear teeth 523 to mesh with the first synchronization teeth 533 and the second synchronization teeth 534, connecting the tilting block 31 to the second rotating shaft 15. The tilting cylinder 32 drives the tilting block 31 to rotate, driving the second rotating shaft 15 to rotate, thereby driving the converter 13 to continue rotating or returning the converter 13 to a safe position. This effectively prevents the converter from losing its drive and overturning or causing other safety accidents under its own gravity after a power outage or tilting motor failure, thus improving safety.

[0043] When power is restored, the tilting motor 20 resumes operation and drives the ratchet 44 to rotate. At this time, the clutch cylinder 46 is still in the retracted state, and the ratchet 44 rotates freely in the cavity 431. It will not interfere with the tilting unit 30 and the protection unit 50, thus avoiding equipment interference caused by the sudden restoration of power or the tilting motor 20 resuming operation, and improving equipment reliability.

[0044] The role and effect of the embodiments

[0045] The steelmaking converter hanging device provided by the present invention includes a converter unit 10, a tilting mechanism 20, a tilting unit 30, and a clutch unit 40. The converter unit 10 includes a base plate 11, a support plate 12, and a converter 13. One end of the support plate 12 is disposed on the base plate 11 and located on both sides of the converter 13. The converter 13 is movably disposed on the support plate 12. The tilting mechanism 20 is disposed on one side of the converter 13. The tilting unit 30 is located on the other side of the converter 13 and connected to the converter 13. One side of the clutch unit 40 is connected to the converter 13, and the other side of the clutch unit 40 is connected to the tilting mechanism 20. The tilting motor 20 is connected. Under normal operating conditions, the tilting motor 20 drives the converter 13, and the tilting unit 30 does not work. In the event of a power outage or a malfunction of the tilting motor, the clutch unit 40 disconnects the tilting motor 20 from the converter 13, and the tilting unit 30 drives the converter 13, thus preventing the converter 13 from failing to move normally. When the tilting motor 20 is powered back or the fault is cleared, the clutch unit 40 remains disengaged, and the tilting motor 20 will not interfere with the drive of the tilting unit 30, thereby preventing equipment damage and improving equipment reliability. Therefore, the steelmaking converter hanging device provided by this invention can return the converter to a safe position or continue driving the converter to rotate in the event of a power outage or tilting motor malfunction, preventing the converter from overturning or other safety accidents under its own gravity after losing drive, improving safety, and preventing motion interference, thus improving equipment reliability.

[0046] Furthermore, when the power supply is restored, the tilting motor 20 resumes its working state, driving the ratchet 44 to rotate. At this time, the clutch cylinder 46 is still in the retracted state, and the ratchet 44 rotates freely in the cavity 431, without interfering with the tilting unit 30 and the protection unit 50. This avoids equipment interference problems caused by the sudden restoration of power supply or the tilting motor 20 resuming its working state, and improves equipment reliability.

[0047] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
