Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking and continuous casting, and more specifically, to a continuous casting steel water tank cover hanger. Background Art

[0002] At present, some domestic steel smelting enterprises use uncovered molten steel tanks for lifting when molten steel is transferred from refining to continuous casting. The transfer process takes a long time, and the temperature of the molten steel inevitably drops during the process. At the same time, since the molten steel tank is not covered, the molten steel and the ladle lining will generate heat radiation and dust pollution to the environment, and the temperature of the upper and lower molten steel tanks is uneven, which is not conducive to the stability of continuous casting.

[0003] At present, the ladle is basically lifted by adding a cover, but this method mostly uses a crane hook to directly connect the ladle cover lifting ear. This connection method is connected to the ladle cover lifting ear through a single hook or a double hook, which can easily cause the ladle cover to deflect during the lifting process, and the deflected ladle cover may be unable to be corrected, thereby affecting the normal pouring of continuous casting production. Therefore, a steel ladle cover lifting device is developed and designed, which can restore the steel ladle cover to its original position under abnormal circumstances to avoid affecting production.

[0006] As a further improvement, the hook and the base plate are perpendicular to each other, and the central axis of the hook is located at the center of gravity of the base plate.

[0007] Furthermore, a reinforcing plate is provided on the connecting plate, and there are multiple reinforcing plates. The multiple reinforcing plates are grouped in pairs and distributed on both sides of the hook, and each group of reinforcing plates is connected to the hook.

[0008] Furthermore, the hook, base plate, connecting plate and reinforcing plate are an integrated structure.

[0021] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0022] See also Figure 1-4 A continuous casting steel tank cover hanger includes a bottom plate 1, which is a triangular hollow frame. The bottom plate 1 adopts a hollow structure. A connecting plate 12 is arranged inside the bottom plate 1. The connecting plate 12 is cross-shaped. The midline of the bottom edge of the bottom plate 1 and the midline of the bottom edge of the bottom plate 1 form a cross-shaped connecting plate 12. This structure can save production materials and reduce manufacturing costs. At the same time, it helps to reduce the weight of the hanger, reduce the load between the hook 2 and the bottom plate 1, and facilitate lifting. In other embodiments, the bottom plate 1 can also be designed as a triangular structure without hollowing; a hook 2 is arranged on the connecting plate 12, and a lifting hole 11 is arranged on the hook 2. The lifting hole 11 is long waist-shaped, and one end of the hook 2 is a smooth arc structure, which can avoid the operator from causing damage to the operator due to improper operation when the operator loads and unloads the hook 2. Injury; A hook 3 is rotatably provided at the bottom of the bottom plate 1, and there are three hooks 3, and the three hooks 3 are installed at the bottom of the three corners of the bottom plate 1 in a one-to-one correspondence; when in use, the overhead crane hook is connected to the hook 2 through the lifting hole 11, and then the hook 3 is connected to the steel ladle cover, and then the overhead crane is started to lift the steel ladle cover to the designated position. Since the hook 3 and the bottom plate 1 are rotatably connected, during the lifting process, if the steel ladle cover is tilted, the hook 3 will be adjusted accordingly, and the steel ladle cover will be balanced during the lifting process under the action of gravity; the lifting device has a simple structure and is easy to operate. Lifting, installation and removal can be achieved by only one person, which can effectively reduce the time required for lifting and reduce the temperature loss of molten steel during lifting, thereby improving product quality.

[0023] In this embodiment, the hook 2 is perpendicular to the base plate 1, and the central axis of the hook 2 is located at the center of gravity of the base plate 1, so that the hooks 3 on the three corners of the base plate 1 are evenly stressed, avoiding the displacement of the steel ladle cover during lifting.

[0024] In this embodiment, a reinforcing plate 4 is provided on the connecting plate 12, and there are multiple reinforcing plates 4. The multiple reinforcing plates 4 are distributed on both sides of the hook 2 in groups of two, and each group of reinforcing plates 4 is connected to the hook 2; there are four reinforcing plates 4 in total, which are divided into two groups and distributed on both sides of the hook 2, and are fixedly connected to the hook 2. The reinforcing plate 2 can strengthen the connection strength between the hook 2 and the base plate 1 to avoid damage to the hook 2 due to hoisting of heavy objects. In other embodiments, the number of reinforcing plates 2 can be increased to 6, 8, etc., to further strengthen the connection strength between the hook 2 and the base plate 1.

[0025] In this embodiment, the hook 2, the bottom plate 1, the connecting plate 12, and the reinforcing plate 4 are an integrated structure, which effectively enhances the overall structural strength of the sling.
