Description

Technical Field

[0001] This utility model relates to the field of ferroalloy processing technology, specifically to a ladle tilting device. Background Technology

[0002] In ferroalloy processing, tilting the ladle is a crucial step in unloading molten iron. Currently, traditional ladle tilting devices mainly suffer from the following problems:

[0003] 1. Mechanical structural defects: The use of fixed supports or simple hinges results in poor stability of the ladle during the tipping process. Wear of mechanical parts (such as rollers and support shafts) can lead to deviations in the tipping angle, and may even cause equipment failure and safety accidents.

[0004] 2. Low level of automation: Manual assistance is required for positioning and locking of the ladle. The operation steps are cumbersome, the labor cost is high and the error rate is high, making it difficult to meet the needs of continuous production.

[0005] 3. Limited production efficiency: The steel ladle needs to be transferred multiple times by overhead crane to achieve processes such as tipping, slag removal, and casting. The intermediate processes are time-consuming and cannot be carried out online, resulting in a longer production cycle. Utility Model Content

[0028] Please see Figures 1 to 8 A ladle tipping device comprises a base 1, a discharge chute 2 mounted on the base 1, a ladle 3, and a tipping mechanism. The base 1 is fixed to the ground and has a chute 4. A slide rail 5 is installed within the chute 4, and a track-driven electric flatcar 6 (a type of electrically powered transport device that runs on a fixed track) is mounted on the slide rail 5. The track-driven electric flatcar 6 moves along the slide rail 5 using its own movement function. A placement slot is provided on the track-driven electric flatcar 6, and the ladle 3 is placed in this slot. The slide rail 5 drives the track-driven electric flatcar 6, which in turn moves the ladle 3. The track-driven electric flatcar 6 has two support seats 12. A support rod 13 is provided on one side of the outer wall of the ladle 3. A placement ring is provided on each support seat 12, and the support rod 13 is fitted with and located within the placement ring. A first locking seat 14 is provided on the other side of the outer wall of the ladle 3. The discharge chute 2 is slidably mounted on one side of the base 1 via a rectangular sliding seat 19 and connected to a winch. The winch provides power to move the discharge chute 2. The discharge chute 2 is detachably bolted to the sliding seat 19 and is inclined. After the molten iron is poured out, slag removal can be performed online by replacing the slag removal chute and using a slag removal car. A mold car is also provided on one side of the discharge chute 2 for subsequent transportation and use of the poured molten iron. A tilting mechanism works in conjunction with the ladle 3 to tilt the ladle 3.

[0029] Specifically,

[0030] The tilting mechanism consists of a hinge seat 7, an L-shaped rotating arm 8, a U-shaped tilting arm 9, a limiting assembly, a first hydraulic cylinder 10, and a second hydraulic cylinder 11. Two hinge seats 7 are provided, bolted or welded to one side of the base 1. Two L-shaped rotating arms 8 are also provided, each with one end hinged to a hinge seat 7. The U-shaped tilting arm 9 is hinged between the two L-shaped rotating arms 8. The limiting assembly consists of a third hydraulic cylinder 15 horizontally mounted on one side of the bottom of the tilting arm 9 and a locking shaft 16 connected to the output shaft of the third hydraulic cylinder 15. A second locking seat 17 is provided at the center of the bottom of the tilting arm 9. The first locking seat 14 and the second locking seat 17 are adapted to each other and both have locking holes 18, which are adapted to the locking shaft 16. Two first hydraulic cylinders 10 are provided, with their bottom ends hinged to the two hinge seats 7 respectively. The telescopic output shafts of the two first hydraulic cylinders 10 are respectively hinged to the bottom sidewalls of the two L-shaped rotating arms 8. Two second hydraulic cylinders 11 are also provided, and their bottom ends are respectively hinged to the upper side walls of the two L-shaped rotating arms 8. The telescopic output shafts of the two second hydraulic cylinders 11 are respectively hinged to both sides of the U-shaped tilting arm 9.

[0031] Two supports 20 are provided on the other side of the base 1, and the two supports 20 are arranged in correspondence with the two hinge seats 7.

[0032] The first hydraulic cylinder 10, the second hydraulic cylinder 11, and the third hydraulic cylinder 15 mentioned above all have a self-locking function, such as a hydraulic cylinder with a hydraulic lock (two-way hydraulic lock) or a hydraulic cylinder with a mechanical lock.

[0033] Working principle of this utility model:

[0034] Initially, the extension and retraction output shafts of the first hydraulic cylinder 10, the second hydraulic cylinder 11, and the third hydraulic cylinder 15 are all in the retracted state. This causes one end of the rotating arm 8 to rest against the support 20, and the tilting arm 9 to be in a retracted state. Figure 1 At the indicated position, the third hydraulic cylinder 15 drives the locking shaft 16 to retract. The ladle 3 is positioned at one end of the base 1 to allow molten iron to enter the ladle 3.

[0035] When molten iron enters the ladle 3 and needs to be poured out, the first hydraulic cylinder 10 is activated. The telescopic shaft of the first hydraulic cylinder 10 extends, driving the rotating arm 8 to rotate around the hinge seat 7, which in turn drives the tilting arm 9 to rotate together. Figure 4 The position is shown. Then, restart the electric flatcar 6, causing it to move on the slide rail 5, thereby moving the ladle 3 to the designated position (e.g., directly below the tilting arm 9). Then, reverse the operation of the first hydraulic cylinder 10, causing its telescopic shaft to retract, driving the rotating arm 8 to rotate in the opposite direction around the hinge seat 7, so that one end of the rotating arm 8 rests against the support 20 again, as shown. Figure 5As shown. At this time, the locking holes 18 on the first locking seat 14 and the second locking seat 17 are aligned. Then, the third hydraulic cylinder 15 is activated, which drives the locking shaft 16 to move horizontally and insert into the locking hole 18. Finally, the second hydraulic cylinder 11 is activated, and the telescopic shaft of the second hydraulic cylinder 11 extends, driving the tilting arm 9 to rotate around the rotating arm 8. Since the support rod 13 on one side of the ladle 3 is compatible with the placement ring on the support seat 12 and is located inside the placement ring, the rotation of the tilting arm 9 can drive the ladle 3 to rotate, causing the ladle 3 to tilt. Figure 7 As shown, the molten iron is poured into the discharge chute 2, and then enters the ingot mold car placed on one side of the discharge chute 2 for subsequent processing and use. After the molten iron is poured out, the discharge chute 2 can be replaced with a slag removal chute and used in conjunction with a slag removal car to perform slag removal operations online, so as to remove the residual molten iron for subsequent use.

[0036] After the molten iron has been poured out, the second hydraulic cylinder 11 is activated in reverse, and its telescopic shaft retracts, allowing the ladle 3 to return to the electric flatcar 6. Then, the third hydraulic cylinder 15 is activated in reverse, and its telescopic shaft retracts, causing the locking shaft 16 to retract and disconnecting the ladle 3 from the tilting arm 9. Next, the first hydraulic cylinder 10 is activated, its telescopic shaft extending and rotating the rotating arm 8. Finally, the electric flatcar 6 is activated in reverse, causing it to reset the ladle 3, allowing the molten iron to re-enter it.

[0037] The discharge chute 2 can be removed by a winch for inspection, maintenance and cleaning.
