[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5A ladle turret for large ladle casting comprises a turret body 1 located between two ladle bodies 2 and a support frame 8 installed between the turret body 1 and the two ladle bodies 2. The inner wall of the turret body 1 is connected with a support assembly, the upper end of the support assembly passes through the turret body 1 and the support frame 8, and is connected with a flip mechanism, the output end of the flip mechanism is connected with a transmission assembly, the other end of the transmission assembly is connected with four rotating blocks 4, the four rotating blocks 4 are respectively connected with two baffles 3, both ends of the two baffles 3 are provided with a discharge port 301 fixedly connected to the upper surface, the two discharge ports 301 of the two baffles 3 are matched and aligned, and a larger opening is formed, the two openings are respectively located above the two ladle bodies 2, and the bottom surfaces of the two baffles 3 are against the upper surfaces of the two ladle bodies 2.

[0023] The ladle turret for large-scale ladle casting in the utility model is similar to the existing ladle turret for large-scale ladle casting, such as the ladle turret for large-scale ladle casting disclosed in the patent with publication number CN111375753. Figures 1 to 5 As shown, when the large ladle casting ladle turret of the utility model drives the two ladle bodies 2 to rotate, it only needs to control the flipping mechanism through the controller of the turret body 1 to flip the two baffles 3 downwards until the two baffles 3 are located directly above the two ladle bodies 2 and stop. Then the turret body 1 operates normally and drives the two ladle bodies 2 to rotate during operation. During the rotation of the two ladle bodies 2, they will always be below the two baffles 3, thereby preventing the molten steel inside the ladle body 2 from splashing out, and also preventing external debris from falling into the ladle body 2 during rotation to pollute the quality of the molten steel inside the ladle body 2.

[0024] Special mention should be made here:

[0025] 1. When the turntable body 1 needs to be inspected or cleaned after running for a period of time, in order to facilitate the operation, the two baffles 3 can be flipped upward and opened through the flip mechanism, so that the turntable body 1 and the baffles 3 can be inspected and cleaned more conveniently.

[0026] 2. The above-mentioned flipping mechanism can also be independently controlled by other controllers, without any specific limitation.

[0027] Please refer to Figure 3 The support assembly includes a support rod 9 and a support seat 12. The outer wall of the support rod 9 is rotatably connected to the inner wall of the turntable body 1. The upper end of the support rod 9 passes through the turntable body 1 and is fixedly connected to the bottom surface of the support seat 12. The side wall of the support seat 12 is connected to the flip mechanism.

[0028] More specifically, when starting to install the entire turntable body 1, you can first fix the lower end of the support rod 9 to the ground, then pass the support rod 9 through the entire turntable body 1, and then connect it to the support base 12, and then connect the flipping mechanism and the transmission assembly to the support base 12. It is simple and easy to install.

[0029] Please refer to Figure 1 , Figure 4 and Figure 5 The flipping mechanism includes a motor 6 and a first gear 13. The outer wall of the motor 6 is fixedly connected to the side wall of the support seat 12. The output shaft of the motor 6 is fixedly connected to one side of the first gear 13. The first gear 13 is connected to the transmission assembly.

[0030] More specifically, when the baffle 3 needs to be controlled to flip, the motor 6 only needs to be turned on through the controller. After the motor 6 is started, the output shaft drives the first gear 13 to rotate, which can drive the transmission assembly to rotate, thereby expanding the two baffles 3 upward or closing them downward.

[0031] Please refer to Figure 4 and Figure 5 The transmission assembly includes a second gear 14, a third gear 15, two transmission rods 7 and two support blocks 5. The two transmission rods 7 are rotatably connected to the inner walls of the two support blocks 5 respectively, and the two ends of the two transmission rods 7 are fixedly connected to the inner walls of the four rotating blocks 4 respectively. The second gear 14 and the third gear 15 are respectively sleeved and fixedly connected to the outer walls of the two transmission rods 7, and the second gear 14 and the third gear 15 are both located between the two support blocks 5.

[0032] More specifically, when the number one gear 13 rotates, it will mesh with and drive the number two gear 14 to rotate. When the number two gear 14 rotates, it will mesh with and drive the number three gear 15 to rotate. Due to the characteristics of the gears, the number two gear 14 and the number three gear 15 rotate in opposite directions, so the two transmission rods 7 can be driven to rotate in two directions, and then the four rotating blocks 4 can be driven to rotate in opposite directions, so that the two baffles 3 can be controlled to expand upward or close downward at the same time.

[0033] Please refer to Figure 2-Figure 4 The support base 12 is fixedly connected with support plates 11 on both sides close to the two baffles 3 , and the upper surfaces of the two support plates 11 are respectively against the bottom surfaces of the two baffles 3 .

[0034] More specifically, because the baffle 3 is in a downward closed state most of the time, by providing the support plate 11, the switch of the motor 6 can be turned off after the baffle 3 is rotated to the downward state, and the support plate 11 can be used to support the bottom of the baffle 3 to prevent the baffle 3 from tilting downward.

[0035] Please refer to Figure 1The bottom surfaces of the two baffles 3 are fixedly connected to two side sealing rails 10, the spacing between the two side sealing rails 10 is not less than the diameter length of the ladle body 2, and the outer wall of the ladle body 2 is slidably connected to the outer wall of the adjacent side of the two side sealing rails 10.

[0036] More specifically, by providing the side sealing rails 10 , firstly, the moving track of the ladle body 2 can be restricted; secondly, both sides of the ladle body 2 can be shielded.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
