Description

Technical Field

[0001] This utility model relates to the technical field of ladle tipping devices, and specifically to a ladle tipping device. Background Technology

[0002] In steelmaking, after each ladle completes a pouring task, it requires maintenance and repair. Steel plants often use offline tilting devices to assist operators in hot repair work such as replacing the sliding gate nozzle, bottom blowing tests, and adding sprue sand. Current ladle tilting devices are either motor-driven or hydraulically operated. Existing motor-driven devices are complex in structure, require significant space and infrastructure, and involve substantial foundation construction. In many cases, the widespread adoption of this type of device is limited by the constraints of process layout space. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a ladle tilting device, comprising a ladle, a rotating frame, a primary reduction mechanism, a secondary reduction mechanism, a linkage mechanism, and a foundation support; the rotating frame includes a U-shaped bracket and a driven rotating shaft and a driving rotating shaft respectively fixedly connected to the left and right ends of the U-shaped bracket; the ladle is fixedly connected between the two ends of the U-shaped bracket; bearing seats are symmetrically arranged on the driving rotating shaft and the driven rotating shaft; the end of the driving rotating shaft away from the U-shaped bracket is the input end; the secondary reduction mechanism is fully suspended on the input end of the driving rotating shaft to achieve transmission connection; the linkage mechanism is horizontally connected between the secondary reduction mechanism and the foundation support; and the primary reduction mechanism and the secondary reduction mechanism are drivenly connected.

[0005] Preferably, the secondary reduction mechanism includes a housing and a large gear and a small gear shaft with transmission connection set in the housing. The housing is connected to the foundation support through a linkage mechanism. The large gear is fixed on the active rotating shaft of the rotating frame through two sets of tangential keys. A large gear bearing is installed at the hub of the large gear, and small gear bearings are installed at both ends of the small gear shaft.

[0006] Preferably, the housing is provided with a large gear bearing mounting hole and a small gear bearing mounting hole. The housing is suspended on the input end of the drive rotating shaft through the large gear bearing mounting hole. The large gear bearing mounting hole is used to install the large gear bearing, and the small gear bearing mounting hole is used to install the small gear bearing.

[0007] Preferably, the primary reduction mechanism includes a motor and a reducer connected in a drive connection, and the primary reduction mechanism is connected to the pinion shaft of the secondary reduction mechanism via a coupling.

[0008] Preferably, the bottom of the housing is also provided with a mounting plate, and the housing is connected to the linkage mechanism through the mounting plate.

The trunnions are fixedly installed in the locking fasteners to fix the ladle between the two ends of the U-shaped bracket.

[0013] This utility model has the following beneficial effects:

[0014] This utility model of a ladle tilting device achieves transmission connection by suspending the secondary reduction mechanism entirely on the input end of the active rotating shaft. A linkage mechanism is horizontally connected between the secondary reduction mechanism and the foundation support, allowing the tilting torque generated by the ladle to be transmitted to the foundation support through the linkage mechanism. This eliminates the need for a dedicated foundation for the secondary reduction mechanism, simplifying the transmission mechanism's structure, resulting in a simpler, more compact structure, smaller footprint, less foundation construction, and more stable and reliable performance. Furthermore, the horizontally connected linkage mechanism converts the ladle's tilting torque into a horizontal force, which is significantly reduced under the action of the secondary reduction mechanism, resulting in less stress on the foundation. This achieves high torque and high speed ratio transmission, thus meeting the process design requirements of ladle tilting devices and solving the problem of steel companies being unable to apply ladle tilting devices due to limited on-site operating space.

[0024] See Figure 1-5As shown, as an embodiment of this utility model, a ladle tilting device is provided, including a ladle 8, a rotating frame 2, a primary reduction mechanism 4, a secondary reduction mechanism 5, a linkage mechanism 6, and a base support 7. The rotating frame 2 includes a U-shaped bracket 2.1 and a driven rotating shaft 2.3 and a driving rotating shaft 2.2 respectively fixedly connected to the left and right ends of the U-shaped bracket 2.1. The ladle 8 is fixedly connected between the two ends of the U-shaped bracket 2.1. Bearing seats 3 are symmetrically arranged on the driving rotating shaft 2.2 and the driven rotating shaft 2.3. The driving rotating shaft 2.2 and the driven rotating shaft 2.3 are rotatably disposed in the bearing seats 3. The end of the driving rotating shaft 2.2 away from the U-shaped bracket 2.1 is the input end. The secondary reduction mechanism 5 is fully suspended on the input end of the driving rotating shaft 2.2 to achieve transmission connection. The linkage mechanism 6 is horizontally connected between the secondary reduction mechanism 5 and the base support 7. The primary reduction mechanism 4 and the secondary reduction mechanism 5 are drivenly connected.

[0025] This utility model's ladle tilting device uses a primary reduction mechanism 4 to drive a secondary reduction mechanism 5, which in turn drives a primary rotating shaft 2.2, causing the rotating frame 2 and the ladle 8 to rotate together to tilt the molten steel. The device achieves transmission by suspending the secondary reduction mechanism 5 entirely on the input end of the primary rotating shaft 2.2. A connecting rod mechanism 6 is horizontally connected between the secondary reduction mechanism 5 and the foundation support 7. This allows the tilting torque generated by the ladle 8 to be transmitted to the foundation support 7 through the connecting rod mechanism 6, eliminating the need for a dedicated foundation for the secondary reduction mechanism 5. This simplifies the transmission mechanism's structure, resulting in a simpler, more compact structure, smaller footprint, less foundation construction, and more stable and reliable performance. Furthermore, the horizontally connected connecting rod mechanism 6 converts the tilting torque of the ladle 8 into a horizontal force. Under the action of the secondary reduction mechanism 5, this horizontal force is significantly reduced, decreasing the stress on the foundation and achieving high torque and high speed ratio transmission. This meets the process design requirements of the ladle tilting device and solves the problem of steel companies being unable to use ladle tilting devices due to limited on-site operating space.

[0026] In this embodiment, the secondary reduction mechanism 5 includes a housing 5.3 and a large gear 5.1 and a small gear shaft 5.2 connected within the housing 5.3. The housing 5.3 is connected to the foundation support 7 via a linkage mechanism 6. The large gear 5.1 is fixed to the drive rotating shaft 2.2 of the rotating frame 2 via two sets of tangential keys 9. A large gear bearing 5.4, a seal, and an end cap are installed at the hub of the large gear 5.1. Small gear bearings 5.5, seals, and end caps are installed at both ends of the small gear shaft 5.2. The housing 5.3 has vertically connected large gear bearing mounting holes 5.6 and small gear bearing mounting holes 5.7. The housing 5.3 is suspended from the input end of the drive rotating shaft 2.2 via the large gear bearing mounting holes 5.6. The large gear bearing mounting holes 5.6 are used to install the large gear bearing 5.4, and the small gear bearing mounting holes 5.7 are used to install the small gear bearing 5.5. This arrangement improves the reliability and stability of the cooperation between the components within the secondary reduction mechanism 5.

[0027] In this embodiment, the primary reduction mechanism 4 includes a motor and a reducer connected by a drive, and the primary reduction mechanism 4 is connected to the pinion shaft 5.2 of the secondary reduction mechanism 5 through a coupling 10.

[0028] In this embodiment, a mounting plate 5.8 is also provided at the bottom of the box body 5.3. The box body 5.3 is connected to the linkage mechanism 6 through the mounting plate 5.8. That is, the front end of the linkage mechanism 6 is connected to the mounting plate 5.8 at the bottom of the box body 5.3, and the rear end of the linkage mechanism 6 is connected to the top of the foundation support 7. This allows the overturning moment generated by the ladle 8 to be better transmitted to the foundation support 7 through the linkage mechanism 6, further reducing the space occupied and the amount of foundation construction.

[0029] In this embodiment, the linkage mechanism 6 includes a connecting rod 6.1 with holes at both ends, and pins 6.2 and spherical bearings 6.3 disposed at both ends of the connecting rod 6.1. The bearings at both ends of the connecting rod can adapt to the deformation and displacement generated by the ladle tilting device during the tilting process, thereby improving the reliability of the ladle 8 tilting operation.

[0030] In this embodiment, the housing 5.3 of the secondary deceleration mechanism 5 includes an upper housing and a lower housing connected vertically, and the upper housing and the lower housing are connected by bolts.

[0031] In this embodiment, the longitudinal section of the U-shaped bracket 2.1 is rectangular to ensure the structural strength of the U-shaped bracket 2.1, thereby ensuring the stability and reliability of the rotation and tilting operation.

[0032] In this embodiment, locking fasteners 1 are fixedly installed on the upper part of the left and right ends of the U-shaped bracket 2.1, and trunnions are respectively provided on the left and right ends of the ladle 8. The trunnions are fixedly installed in the locking fasteners 1 to fix the ladle 8 between the two ends of the U-shaped bracket 2.1, so as to ensure the connection stability between the ladle 8 and the U-shaped bracket 2.1.
