Description

Technical Field

[0001] The present application relates to the technical field of ore transport equipment, and in particular to a cold hopper for a smelting converter. Background Art

[0002] The normal operation of converter production includes feeding, opening the air, adding flux, adding cold material, slag removal, etc. Adding cold material is one of them. When the converter is blowing, the heat is relatively sufficient. In order to maintain a certain furnace temperature, cold materials need to be added to adjust, such as scrap steel, dolomite, lime and other cold materials. Usually, the cold materials used in copper making are crude copper blocks and electrolytic residual electrodes.

[0003] The cold material hopper is used to transport cold materials to the converter. The cold material hopper currently used is usually a cylindrical structure with through holes on the left and right sides of the top. A steel rope is passed through the two through holes and fixed into a steel rope ring by a clamp, thus serving as a sling; a hanging plate is also provided at the tail. The lifting equipment used to lift the cold material hopper is provided with a main hook and an auxiliary hook. The main hook is hung on the steel rope and is used to lift the cold material hopper, and the auxiliary hook is hung on the hanging plate. When the cold material needs to be dumped, the main hook does not move, and the auxiliary hook is lifted to make the cold material hopper rotate and tilt, so as to pour out the cold material.

[0004] When loading cold materials, the cold material hopper needs to be unhooked first and then the hook needs to be hung after loading. Since the steel rope is flexible, workers are needed to assist when hanging the main hook. In addition, the hanging holes on the hanging plates of traditional cold material hoppers are small, so workers are also needed to assist when hanging the auxiliary hook. Frequent hooking operations will not only increase the labor intensity of workers, but also when hooking, workers need to be in close contact with the main and auxiliary hooks, which poses a great safety hazard. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related technology, the present application provides a cold hopper for a smelting converter. The device can facilitate workers to operate lifting equipment for hooking without manual assistance, thereby reducing the labor intensity of workers and ensuring the safety of the hooking process.

[0006] The present application provides a cold material hopper for a smelting converter, comprising a hopper body, hanging ears, a hanging plate, a U-shaped clamp, an iron chain, and a hanging ring. The hopper body is in a right-angled trapezoidal structure, and hanging ears are symmetrically arranged on its left and right sides. The hanging ears are located in the middle of the long side of the hopper body so that the center of gravity of the hopper body is biased toward the tail side. A hanging plate is also arranged on the tail side of the hopper body, and a detachable U-shaped clamp is installed on the hanging plate. One end of the iron chain is connected to the U-shaped clamp, and the other end is connected to the hanging ring.

[0024] See also Figure 1 The cold material hopper for smelting converter includes a hopper body 1, a hanging ear 2, a hanging plate 3, a U-shaped clamp 4, an iron chain 6, and a hanging ring 7. The hopper body 1 is a right-angled trapezoidal structure, and the hanging ears 2 are welded on both sides. The hanging ears 2 are cylindrical, and the hanging ears 2 on the left and right sides are symmetrical to each other. The hanging ears 2 are used to connect the main hook of the lifting equipment. Further, in order to improve the stability of the hanging ears 2, a plurality of stiffening plates 22 are evenly arranged at the welding point between the hanging ears 2 and the hopper body 1, and the number of stiffening plates 22 is 3-6. Further, in order to prevent the main hook from slipping off the hanging ear 2 during lifting, a limiting plate 21 is arranged at the end of the hanging ear 2. The limiting plate 21 is concentric with the hanging ear 2, and the diameter of the limiting plate 21 is larger than the hanging ear 2, so that the main hook can be blocked to prevent the main hook from slipping off, thereby ensuring the safety of the lifting process.

[0025] See also Figure 2The inclined surface of the bucket body 1 is the front side, which is the dumping end 11 for pouring out the cold material. The corresponding vertical surface is the tail side, which is connected to the auxiliary hook of the lifting equipment. The hanging ear 2 is welded at the middle position of the long side of the bucket body 1, so that the center of gravity of the bucket body 1 is biased to the tail side. A hanging plate 3 is also welded on the tail side of the bucket body 1. The hanging plate 3 is provided with a through hole. The U-shaped clamp 4 is provided with a connecting hole corresponding to the through hole. When in use, the connecting hole of the U-shaped clamp 4 is aligned with the through hole of the hanging plate 3, and then connected through the fixing pin 5. When the U-shaped clamp 4 needs to be removed, the fixing pin can be taken out, which is convenient and quick. One end of the iron chain 6 is connected to the U-shaped clamp 4, and the other end is connected to the hanging ring 7.

[0026] See also Figure 3 A hanging ring placement rack 8 is welded on the rear side of the bucket body 1. The hanging ring 7 is a "convex" shaped structure, and the hanging ring 7 can be plugged and fixed in the hanging ring placement rack 8. The traditional cold material bucket needs to connect the hanging plate directly to the auxiliary hook of the lifting equipment. Since the hanging hole at the hanging plate is small, workers are required to assist in hooking. When hooking, the workers have to come into close contact with the auxiliary hook, which poses a great safety hazard. However, the present application sets a hanging ring 7 and uses an iron chain 6 to connect the hanging ring 7 with the hanging plate 3. When in use, the auxiliary hook can be hooked on the hanging ring 7. Compared with the traditional method of hooking the auxiliary hook at the hanging plate, the method adopted by the present application has the following advantages: first, the hanging plate 3 is usually located at the bottom of the bucket body 1. When the hanging operation is performed, it is easily blocked by the bucket body 1, which is inconvenient to operate. The hanging ring 7 is set at the top of the bucket body 1, and there is no obstruction around, which is more convenient for hooking; second, the hole on the hanging ring 7 is larger, which is more convenient for the auxiliary hook to pass through. The worker can directly control the lifting equipment to hook, and no manual assistance is required, which ensures the safety of the hooking process.

[0027] It needs to be further explained that the main hook of the lifting equipment needs to be adaptively improved according to the size of the bucket body 1, and the single hook is changed to a double hook. The width between the double hooks corresponds to the distance between the middle positions of the two hanging ears 2. When in use, the height of the main hook is lowered to be flush with the hanging ears 2, and the main hook can be hung on the hanging ears 2 on both sides by translation, without the need for workers to assist in hooking.

[0028] Specific working process:

[0029] Before use, place the bucket body 1 in a suitable position so that the direction of the bucket body 1 corresponds to the lifting equipment. The worker inserts and fixes the hanging ring 7 on the hanging ring placement frame 8, and arranges the iron chain 6 to prevent the iron chain 6 from being entangled and knotted, completing the preparation work;

[0030] When in use, the cold material is evenly spread in the bucket body 1 so that the center of gravity of the bucket body 1 is biased towards the tail end;

[0031] After the loading is completed, the worker controls the main hook of the lifting equipment to descend. When the height of the main hook is flush with the hanging ear 2, the main hook is controlled to move horizontally so that the main hook is hooked on the hanging ear 2 to complete the main hook hanging; then the worker controls the auxiliary hook of the lifting equipment to descend. When the height of the auxiliary hook is flush with the hanging ring 7, the auxiliary hook is controlled to move horizontally so that the auxiliary hook is hooked on the hanging ring 7. After the auxiliary hook is hung, the auxiliary hook is first lifted, the hanging ring 7 is pulled out from the hanging ring placement frame 8, and the iron chain 6 is tightened, and then the main hook and the auxiliary hook are lifted at the same time to lift the bucket body 1.

[0032] When unloading, the lifting equipment is controlled to lift the auxiliary hook, and the rear side of the bucket body 1 is lifted, so that the bucket body 1 is rotated and tilted around the hanging ear 2, so that the cold material is poured out from the dumping end 11.

[0033] On the basis of the above embodiment, since some cold materials are large and irregular in size, after being loaded into the bucket body 1, there is a situation where the cold materials block the hanging ring 7, resulting in obstruction of the hooking of the auxiliary hook. At this time, the auxiliary hook can be moved to the vicinity of the hanging ring 7 and stopped steadily, and the worker takes the hanging ring 7 from the hanging ring placement rack 8 and manually hooks the hanging ring 7 to the auxiliary hook, thereby completing the hooking operation. The iron chain 6 can ensure freedom when moving the hanging ring 7, so as to facilitate dealing with such situations.

[0034] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
