Description

Technical Field

[0001] This invention relates to the field of electrolytic aluminum technology, and in particular to a device for removing the hook from the molten iron ladle of an electrolytic aluminum anode. Background Technology

[0002] A ladle is a special container designed for loading, transporting, and pouring molten iron, playing a crucial role in the steel production process. This container is typically made of high-temperature resistant, high-strength materials, such as high-quality refractory bricks, special steel, or high-strength cast steel, to ensure structural stability and integrity when bearing high-temperature molten iron. The design of the ladle also considers ease of operation and safety, usually equipped with crane hooks, tilting mechanisms, and other auxiliary facilities to facilitate efficient lifting, moving, and pouring operations. In the electrolytic aluminum anode assembly workshop, during casting operations, a ladle filled with high-temperature molten iron is hoisted and then operated by personnel to pour the molten iron onto each anode claw individually.

[0003] Therefore, before using the molten iron ladle, the hook must be attached to the ladle's lifting ring. When unhooking the ladle, due to its height, personnel must stand close to the ladle on a platform to perform the unhooking operation, making the process cumbersome and inefficient. Because the ladle contains high-temperature liquid, the ladle itself and its surroundings are extremely hot; personnel are at high risk of burns if they are not careful when unhooking. Throughout the process, personnel are exposed to intense heat, easily leading to fatigue. Furthermore, poor coordination between personnel and the crane operator during unhooking operations can easily result in injuries such as crushing injuries. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a hook removal device for an electrolytic aluminum anode molten iron ladle, comprising a long rod with a handle at its lower end, a heat insulation plate between the handle and the long rod, and a fork at the upper end of the long rod. With this technical solution, the hook can be easily removed by using the fork to press against the hook, and the handle allows for operation from a distance, greatly reducing the risk. Furthermore, the heat insulation plate can isolate a certain amount of heat radiation, further preventing burns to the hands.

[0005] Furthermore, hooks are fixedly installed at both ends of the fork. With the above technical solution, if lateral movement is required during hook removal, the hook needs to be engaged between the fork and the hook to facilitate lateral movement and downward hooking, thus allowing for adjustments at more angles.

[0006] Furthermore, the heat insulation plate and the long rod are fixed together by fixing bolts.

[0007] Furthermore, a fixing plate is fixedly mounted on the upper end of the handle, and the fixing plate is fixedly connected to the heat insulation plate by fixing bolts. Through the above technical solution, both the handle and the heat insulation plate are detachable, making them easier to store. At the same time, it reduces maintenance costs in case of damage, requiring only the replacement of the corresponding parts.

[0008] Furthermore, the fork is hinged to the long rod, and a torsion spring is fixedly installed between the fork and the long rod.

[0009] Furthermore, the lower end of the fork is hinged to a connecting rod one, the lower end of the connecting rod one is hinged to a connecting rod two, and the connecting rod two is slidably connected to the lower end of the long rod.

[0010] Furthermore, the long rod has a hollow structure, and a filling block is fixedly installed on the lower side inside the long rod.

[0011] Furthermore, a push plate is fixedly mounted on the lower end of the second connecting rod, and the push plate is provided with an arc-shaped groove. Through the above technical solution, the fork can be rotated to adjust different angles, the torsion spring can keep the fork at a fixed angle, the angle of the fork can be changed by the first connecting rod and the second connecting rod, and the setting of the push plate and the arc-shaped groove can make it more suitable for one-handed operation.

[0012] The advantages of this utility model compared with the prior art are:

[0013] (1) With the above technical solution, the hook can be easily removed by using a fork to hold the hook, and the operation can be carried out from a distance by holding the handle, which greatly reduces the danger. In addition, the heat insulation plate can isolate a certain amount of heat radiation, further preventing burns to the hands.

[0014] (2) Through the above technical solution, if lateral movement is required during the hook removal process, the hook needs to be locked between the fork and the bent hook, which can drive lateral movement and also hook downwards, satisfying more angle adjustments.

[0015] (3) With the above technical solution, the handle and the heat insulation plate are detachable, which makes them easier to store. At the same time, the maintenance cost is reduced after damage, and only the corresponding parts need to be replaced.

[0016] (4) Through the above technical solution, the fork can be rotated to adjust different angles, the torsion spring can keep the fork at a fixed angle, the angle of the fork can be changed by connecting rod one and connecting rod two, and the push plate and arc groove can be set to be more suitable for one-handed operation.

It includes a long rod 3, which can be made from scrap steel pipe; in this embodiment, it is two meters long. A handle 1 is attached to the lower end of the rod 3. The handle 1 is made of heat-insulating material, such as wood or rubber; in this embodiment, it is rubber. A heat-insulating plate 2 is installed between the handle 1 and the rod 3. The heat-insulating plate 2 is an arc-shaped plate that can block heat and falling debris. A fork 4 is attached to the upper end of the rod 3. The fork 4 is arc-shaped, with the arc facing upwards. After the overhead crane hook lifts the ladle to the designated position, the fork 4 is used to lift the hoisting rope of the ladle and remove it from the hook. Through this technical solution, the hook can be easily removed by using the fork 4 to hold the hook. Holding the handle 1 allows for operation from a distance, greatly reducing the risk. Furthermore, the heat-insulating plate 2 can isolate a certain amount of heat radiation, further preventing burns to the hands.

[0024] In this embodiment, hooks 5 are fixedly installed at both ends of the fork 4. The hooks 5 converge inward in an arc shape, and the lifting rope can be locked between the fork 4 and the hooks 5. With the above technical solution, if lateral movement is required during the hook removal process, the hook needs to be locked between the fork 4 and the hooks 5, which can drive lateral movement and also hook downward, satisfying more angle adjustments.

[0025] In this embodiment, the heat insulation plate 2 and the long rod 3 are fixed together by four fixing bolts 6, located at the four corners of the lower side of the heat insulation plate 2, using hexagonal bolts. A fixing plate 7 is fixedly mounted on the upper end of the handle 1, and the fixing plate 7 is fixedly connected to the heat insulation plate 2 by four fixing bolts 9. Through this technical solution, both the handle 1 and the heat insulation plate 2 are detachable, making them easier to store. Furthermore, it reduces maintenance costs in case of damage, requiring only the replacement of the corresponding parts.

[0026] The fork 4 is hinged to the long rod 3. A pivot 11 is fixedly mounted on the upper end of the long rod 3. A connecting lug 15 is fixedly mounted on the lower middle part of the fork 4. The connecting lug 15 is rotatably mounted on the pivot 11. The fork 4 is hinged to the long rod 3 through the cooperation of the connecting lug 15 and the pivot 11.

A connecting lug 2 16 is fixedly mounted on the lower end of the fork 4, located to one side of the connecting lug 15. The connecting rod 10 and the connecting lug 2 16 are rotatably connected. The fork 4 is hinged to the connecting rod 10 through the connecting lug 2 16. A connecting rod 2 13 is hinged to the lower end of the connecting rod 10, and the connecting rod 2 13 is slidably connected to the lower end of the long rod 3. The long rod 3 has a hollow structure. A filling block 17 is fixedly installed on the lower side inside the long rod 3. The filling block 17 is detachably installed inside the long rod 3. The filling block 17 has a hole inside, which is slidably connected to the connecting rod 2 13, providing a stable sliding track for the connecting rod 2 13.

[0027] In this embodiment, a push plate 8 is fixedly mounted on the lower end of the second connecting rod 13, and an arc-shaped groove 14 is provided on the push plate 8. Through the above technical solution, the fork 4 can be rotated to adjust different angles. The torsion spring 12 can keep the fork 4 at a fixed angle. The angle of the fork 4 can be changed by the first connecting rod 10 and the second connecting rod 13. The push plate 8 and the arc-shaped groove 14 are more suitable for one-handed operation. In the initial state, the fork 4 is in an inclined state, which can complete the hook removal operation. When it is necessary to change the angle, the thumb holding the handle 1 pushes the push plate 8 forward. Anti-slip texture can be provided on the arc-shaped groove 14. The second connecting rod 13 pushes the first connecting rod 10, the first connecting rod 10 pushes the fork 4, and the fork 4 rotates to the other side and tilts. After releasing the hand, it returns to its original position under the action of the torsion spring 12.
