Description

Technical Field

[0001] The present invention relates to the technical field of billet conveying, and specifically relates to a billet crossing and steel fishing and steel transferring device. Background Technique

[0002] A billet is a product obtained after the molten steel smelted in a steelmaking furnace is cast. Billets can be mainly divided into two types from the manufacturing process: ingot cast billets and continuous cast billets. A billet refers to a semi-finished product used for producing steel, and generally cannot be directly used by society. After the billet is cast, it needs to be conveyed.

[0003] However, there are some problems in the existing billet conveying process. The existing billet conveying device is not convenient for conveying multiple billets during use. The types of billets required by each workshop are different, and it is not convenient to separately store and convey different types of billets, which may affect the subsequent processing efficiency. At the same time, it is not convenient to unload the billets, and it is not convenient to adjust the angle of billet unloading, which will reduce the conveying efficiency of the device. Moreover, the conveying method of billets is relatively single, reducing the diversification of the device. Currently, the common way to limit the billets is to wrap a limiting device on the surface of the billets. However, only the surface of multiple billets may be limited. If the billets tilt, the billets in the center may fall, resulting in damage. Summary of the Invention

[0032] Further, please refer to Figure 1-6 、 Figure 13-14 The limiting mechanism includes four connecting plates 8. The four connecting plates 8 are respectively fixedly connected to one end of the adjacent connecting threaded rod 9 away from the threaded cylinder 10. Connecting holes are respectively opened at the four corners of the inner cavity of the connecting plate 8.

Blind holes are respectively opened on one side of the second T-shaped plates 11 close to the center of the connecting plate 8. Springs 20 are respectively fixedly connected in the inner cavities of the blind holes. One end of the spring 20 away from the second T-shaped plate 11 is respectively fixedly connected to the side wall of the inner cavity of the adjacent first T-shaped groove. First L-shaped plates 12 are respectively fixedly connected to one side of the second T-shaped plates 11 away from the connecting plate 8. Connecting grooves are respectively opened on one side of the first L-shaped plates 12 away from the second T-shaped plates 11. Vertical rods 39 are respectively hinged in the inner cavities of the connecting grooves. Vertical plates 13 are respectively fixedly connected to one end of the vertical rods 39 away from the first L-shaped plates 12. Two limiting grooves are respectively opened on the outer side edges of the connecting plates 8. Second L-shaped plates 15 are respectively arranged in the inner cavities of the limiting grooves. Adjusting grooves are respectively opened on one side of the second L-shaped plates 15 close to the center of the connecting plate 8. Limiting elastic plates 19 are respectively fixedly connected in the inner cavities of the adjusting grooves. One side of the limiting elastic plate 19 away from the second L-shaped plate 15 is fixedly connected to the side wall of the inner cavity of the adjacent limiting groove. Connecting elastic plates 16 are jointly fixedly connected to one side of the adjacent two second L-shaped plates 15 away from the connecting plate 8;

[0033] One end of the connecting rod 18 away from the second L-shaped plate 15 is fixedly connected to the supporting plate 17. Limiting frames 35 are respectively fixedly connected to one side of the vertical plates 13 away from the connecting elastic plate 16. Elastic U-shaped plates 14 are jointly arranged in the inner cavities of the two limiting frames 35 on the same side. Third threaded holes are respectively opened on one side of the limiting frames 35 away from the vertical plates 13. Limiting threaded rods 37 are respectively threadedly connected in the inner cavities of the third threaded holes. One end of the limiting threaded rod 37 close to the connecting elastic plate 16 is fixedly connected to the pushing plate 36. The pushing plate 36 is located in the inner cavity of the adjacent limiting frame 35. Rotating disks 38 are respectively fixedly connected to one end of the limiting threaded rod 37 away from the pushing plate 36;

[0034] Place the billet at the adjacent connecting plate 8. The second L-shaped plate 15 and the cooperating connecting elastic plate 16 can limit billets of different sizes, while the vertical plate 13 can limit the left and right sides of the billet to prevent the billet from accidentally falling. At the same time, the connecting plate 8 can be used at the ring 2 and can also be installed in other equipment to cooperate with the hoisting equipment to convey the connecting plate 8 and the billet.

[0035] Working principle: When the device starts to work, the operator places billets of different types on one side of the adjacent connecting plate 8 through external equipment. When multiple billets are placed on the inner side of the connecting plate 8, the second L-shaped plate 15 first contacts the billet. The second L-shaped plate 15 and the cooperating connecting elastic plate 16 conduct preliminary limiting on the billet. If there are a large number of billets at the connecting plate 8, the billet drives the second L-shaped plate 15 to move, and the second L-shaped plate 15 drives the limiting elastic plate 19 to stretch, so as to cooperate with different numbers of billets for limiting. After the second L-shaped plate 15 and the connecting elastic plate 16 conduct preliminary limiting on the billet, move the first L-shaped plate 12 left and right. The first L-shaped plate 12 drives the second T-shaped plate 11 to move, and the second T-shaped plate 11 drives the spring 20 to stretch. The first L-shaped plate 12 drives the vertical plate 13 to move through the vertical rod 39, swing the vertical plate 13, and the vertical plate 13 drives the vertical rod 39 to swing, and adjust the vertical plate 13 to a vertical state. The vertical plate 13 will limit the left and right sides of the billet to prevent the billet in the center from being displaced and falling during the conveying process of multiple billets. Place one side of the elastic U-shaped plate 14 in the adjacent limiting frame 35 respectively, adjust the rotating disc 38, the rotating disc 38 drives the limiting threaded rod 37 to rotate, the limiting threaded rod 37 drives the push plate 36 to rotate, and the push plate 36 will limit the elastic U-shaped plate 14, so as to ensure that the vertical plate 13 is always in a vertical state to conduct further limiting on the billet;

[0036] After all billets of different types are placed on the device, the device is pushed to move. The device moves by means of existing roller technology. When the device moves to the workshop, the billets required by the current workshop are selected. The operator rotates the ring 2, and the ring 2 drives the first T-shaped plate 7 to rotate. The first T-shaped plate 7 rotates inside the T-shaped annular groove inside the limit ring 1. The ring 2 drives the connecting plate 8 to move through the connecting threaded rod 9 and the threaded barrel 10. The connecting plate 8 drives the billet to rotate, and rotates the required billet to the lower part of the device. Then, the rotating disk 38 is adjusted. The rotating disk 38 drives the limit threaded rod 37 to rotate. The limit threaded rod 37 drives the push plate 36 to rotate. The push plate 36 moves away from the elastic U-shaped plate 14, and the elastic U-shaped plate 14 is taken out. The vertical plate 13 will return to the horizontal state again. The operator pushes the lower billet to the left or right, and the billet will fall back onto the top of the arc-shaped plate 5. At the same time, the electric telescopic rod 21 is started through an external power supply. The electric telescopic rod 21 drives the movable block 40 and the T-shaped block 26 to move through the U-shaped block 25. The T-shaped block 26 moves at the bottom of the arc-shaped plate 5 and adjusts the inclination angle of the arc-shaped plate 5. The arc-shaped plate 5 swings through the hinge, thereby changing the blanking angle of the billet and improving the blanking efficiency of the billet.

[0037] In the above operation, the connecting plate 8 is in a state of being installed on the ring 2. The connecting plate 8 can not only be used as a part of the whole device, but also be installed in other equipment. When it is installed in other equipment and there is a billet on one side of the connecting plate 8, the operator first rotates the threaded barrel 10. The threaded barrel 10 moves away from the connecting threaded rod 9, and moves the hook 31. The hook 31 drives the elastic rope 30 to move. The hook 31 is sleeved at the hole on the lower connecting plate 8, and the elastic rope 30 is pulled. The elastic rope 30 drives the lower connecting plate 8 to move upward through the hook 31. The connecting plate 8 drives the connecting threaded rod 9 to move, and moves the connecting threaded rod 9 away from the ring 2. Thus, the lower connecting plate 8 can be taken out from the ring 2. By connecting a hoisting device to the connecting plate 8, the connecting plate 8 and the billet can be hoisted and transported.
