Description

Technical Field

[0001] This utility model provides a tilting device for a chuck, belonging to the field of metallurgical production technology. Background Technology

[0002] After the ladle smelting operation is completed, the ladle is tilted as a whole to empty the slag and molten iron. Traditionally, this is done using a crane, with two methods: one involves using a crane to lift the tilting frame, thus tilting the ladle; this method is often used for ladles with a volume less than 15m³. The other method involves using a crane to lift the ladle, moving it to a designated position, and then using a secondary hook to lift and tilt it; this method is often used for ladles with a volume ≥15m³. However, both methods increase the crane's operating frequency. Furthermore, the ladle sways during crane movement, potentially causing molten iron to overflow and leading to accidents. Additionally, the swaying can cause the molten iron and slag to churn, affecting the quality of the ferroalloy. Lifting and tilting the ladle with a crane is a high-altitude operation, with a high degree of difficulty and high workload for the operators.

[0003] Based on this, Chinese utility model patent (CN 203091733 U) proposes an industrial silicon ladle lifting device with a hydraulic tilting mechanism. The device includes a ladle body, a trunnion, a ladle support frame, and a hydraulic tilting mechanism. The hydraulic tilting mechanism includes a crank, a hydraulic rod, and a hydraulic cylinder. The trunnion is welded to the outer wall of the ladle body and connected to the ladle support frame. One end of the crank is fixed to the trunnion, and the other end is connected to the hydraulic rod and hydraulic cylinder. In use, the push and pull of the hydraulic cylinder drives the crank to rotate. When the crank rotates, it drives the trunnion on the ladle to rotate, thereby tilting the ladle and achieving the purpose of tilting it. This operating method requires a relatively large driving force.

[0004] Chinese utility model patent (CN 219474246 U) discloses a hydraulic tilting electric arc furnace, which includes a support frame and a furnace body. A hydraulic cylinder is mounted on the support frame, and a connector is mounted on the outer wall of the furnace body. A heat insulation structure is mounted on the connector, and a connecting block is rotatably mounted on the heat insulation column of the heat insulation structure. The base block on the connecting block is connected to the hydraulic cylinder on the hydraulic cylinder. When tilting, the hydraulic cylinder lifts one side of the furnace body, thereby causing the material inside the furnace body to pour out. This tilting method has poor stability when turning the furnace body over. Utility Model Content

[0005] To address the technical problems of high operational difficulty, low safety, and poor stability during the tilting and turning of bags, this utility model proposes a bag tilting and turning device. The aim is to improve the safety of the tilting operation, reduce the operational difficulty, and enhance the stability of the bag during the tilting process by improving the hardware structure of the bag tilting and turning device.

[0010] Furthermore, the first connecting part is a columnar structure, the part of the tilting hook that cooperates with the first connecting part is an arc structure, and the tilting hook and the first connecting part are coaxially arranged.

[0011] Furthermore, the lifting lug is provided with a second connecting part, and the first base is provided with a third connecting part, and the second connecting part and the third connecting part are rotatably connected.

A tilting hook 12 is fixedly connected to the driving device 3. The tilting hook 12 has an arc-shaped structure at its mating point with the first connecting parts 9. The tilting hook 12 and the first connecting parts 9 are coaxially arranged and rotatably connected. More specifically, the lifting device 13 is fixedly connected to the outer side wall of the lower end of the bag body 1. In this embodiment, four lifting devices 13 are provided, and two sets of driving devices 3 are provided.

In this embodiment, the tilting hook 12 includes a main hook and a secondary hook. Two first connecting parts 9 are rotatably connected to each lifting device 13, and the two first connecting parts 9 respectively correspond to the main hook and the secondary hook.

[0031] Several lifting lugs 5 are provided on the bag body 1 at a position away from the lifting device 13.

When the power output end of the driving device 3 acts on the tilting hook 12 and tilts the package body 1 through the first connecting part 9, the first connecting part 9 rotates within the tilting hook 12, and the second connecting part 10 rotates around the third connecting part 11 to change the angle of the package body 1 relative to the cradle 2.
