Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical engineering equipment, and more specifically, to a cable protection device for a ladle car and a ladle car. Background Art

[0002] The main steelmaking method in the world today is converter steelmaking, which accounts for about 60% of the total world steel output. During the steelmaking production process, a ladle car can complete the ground transportation operation of the ladle, so as to meet the requirements of production processes such as tapping, pouring the remaining molten steel, and refining. The ladle car is an important device for transporting molten steel in the steelmaking process and is one of the important equipment on the steelmaking production line; the ladle car is a vehicle running along the track composed of multiple pairs of wheels driven by electric energy; after the converter smelting is completed, the molten steel is poured from the tapping hole into the empty ladle on the ladle car under the furnace by tilting the converter, and the ladle car transports the ladle with molten steel into the next process. In actual production, after the ladle car cable comes out of the cable reel, it is tied with a shackle and then passes through the inside of the ladle car and is connected to the motor. The ladle is placed on the ladle car. When pouring the molten steel, the molten steel is poured into the ladle from above. The ladle car cable is directly below the converter. Due to reasons such as unstable operation during the tapping process, the molten steel and slag are very likely to splash irregularly when pouring the molten steel. When the molten steel and slag fall on the ladle car cable, the ladle car cable will be burned out, causing the ladle car to fail to operate, affecting the normal progress of the next process, and further affecting the normal production, resulting in waste of production resources and a decrease in production efficiency.

[0029] The various embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. In each of the drawings, the same elements are denoted by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0030] The present invention provides a cable protection device for a ladle car. Refer to Figure 1 , the cable protection device for the ladle car includes: a cable inlet bracket 2, a cantilever 1, and a support leg 3; wherein, the cantilever 1 is a hollow tubular structure; the cable inlet bracket 2 is fixedly provided at one end of the cantilever 1, and a channel for introducing the cable into the interior of the cantilever 1 is provided on the cable inlet bracket 2; two support legs 3 are horizontally and fixedly provided on one side of the cantilever 1, the support leg 3 is a hollow tubular structure, and the support leg 3 is used for fixedly connecting to the side of the ladle car; one of the support legs 3 is communicated with the interior of the cantilever 1 for introducing the cable penetrating into the cantilever 1 into the interior of the ladle car.

[0031] As Figure 7As shown in the figure, the cable protection device of the ladle car is installed at the rear side position of the ladle car 8 through two legs 3. The cantilever 1 extends outward to the rear of the ladle car 8, and the cable inlet bracket 2 extends a certain distance out of the rear end face of the ladle car 8, so that the cable protection device of the ladle car is far away from the ladle position in the middle of the ladle car 8, and the inlet position on the ladle car 8 is moved backward. After installing the cable protection device of the ladle car, after the cable comes out of the cable reel, it enters from above the cable inlet bracket 2, then passes through the channel of the cable inlet bracket 2 into the cantilever 1, and goes straight to the rear leg 3 position on the cantilever 1 and penetrates into the leg 3, and then enters the ladle car interior. When the ladle car receives molten steel, the cable is not directly below the tapping hole of the converter, greatly reducing the possibility of molten steel and slag falling on the cable. Under the protection of the cantilever 1 and the leg 3, the cable can avoid being ablated and damaged by the falling molten steel and slag, extend the service life of the ladle car cable, reduce the failure rate of the ladle car, and thus ensure the production efficiency.

[0032] See Figures 2 to 5 , the cable inlet bracket 2 includes two spaced-apart support plates 21, and the two support plates 21 are connected by two spaced-apart support plates 22, and a channel for passing the cable is formed between the two support plates 22. As Figure 3 shown, in this embodiment, the support plate 21 has a T-shaped structure, and the horizontal section and the vertical section are connected by an arc transition. The support plate 22 has an arc-shaped structure, and the two arc-shaped support plates 22 are arranged back to back to form a flared channel. A notch is provided at the lower part of the support plate 22 on the side close to the cantilever 1 so that the channel is connected to the inside of the cantilever 1, so that the cable can be smoothly introduced into the cantilever 1. The upper end of the support plate 22 is an arc-shaped structure bent downward, so that the cable can enter the channel of the cable inlet bracket 2 more smoothly and avoid being scratched and damaged by the end of the support plate 22. In this embodiment, the lower end of the cable inlet bracket 2 is welded and fixed to one end of the cantilever 1. In order to enhance the firmness during welding connection, reinforcing plates are also vertically welded on the two support plates 21 to increase the contact area between the cable inlet bracket 2 and the end of the cantilever 1, so that the cable inlet bracket 2 and the cantilever 1 are more firm after welding.

[0033] A cable fixing pipe clamp 7 is provided inside one of the support plates 21, and the cable fixing house is located in the channel. By providing the cable fixing pipe clamp 7 inside the support plate 21 of the cable inlet bracket, the cable fixing pipe clamp 7 fixes the cable passing through the channel, preventing the pulling during the operation of the ladle car from tearing the wiring of the cable and causing the ladle car to malfunction.

[0034] In this embodiment, both the cantilever 1 and the support leg 3 are made of rectangular steel pipes. To improve the cable protection effect, a cable conduit 6 for threading the cable is provided inside the cantilever 1. The cable conduit 6 is arranged at the bottom inside the cantilever 1. The cable is threaded through the cable conduit 6, and through the double protection of the cantilever 1 and the cable conduit 6, it is possible to avoid heat damage to the cable caused by molten steel and slag falling on the cantilever 1. The cable conduit 6 can be fixed to the bottom inside the cantilever 1 by a limit clamping plate arranged inside the cantilever 1.

[0035] Further, two baffles 4 are spaced apart on the top of the cantilever 1. The baffles 4 extend along the length direction of the cantilever 1. Fire-resistant materials are placed between the two baffles 4, thereby improving the protection effect on the cable.

[0036] Further, the support leg 3 is detachably connected to the cantilever 1. Specifically, one connecting plate 5 is respectively arranged at one end of the support leg 3 facing the cantilever 1 and at the position on the cantilever 1 where the support leg 3 is connected. Bolt holes are provided on the connecting plate 5. The connecting plate 5 on the support leg 3 is connected to the corresponding connecting plate 5 on the cantilever 1 by bolts. As Figure 1 shown, two groups of bolt holes are respectively arranged at the upper and lower ends of the connecting plate 5. The position of the connecting plate 5 where the bolt holes are provided extends out of the upper and lower end faces of the support leg 3 and the cantilever 1, thereby facilitating the detachable connection between the support leg 3 and the cantilever 1. Among them, the middle of the connecting plate 5 on the support leg 3 is a rectangular hole, which is convenient for threading the cable. Long circular holes are provided on one side of the cantilever 1 and on the connecting plate 5 of the cantilever 1, which is convenient for the cable in the cantilever 1 to penetrate into the support leg 3. In this embodiment, the cable penetrates into the ladle car interior from the support leg 3 far away from the cable inlet bracket 2. Therefore, long circular holes are only provided on the connecting plate 5 of the cantilever 1 far away from the cable inlet bracket 2 and on the corresponding side part of the cantilever 1. The end of the cable conduit 6 arranged inside the cantilever 1 does not exceed the position of the long circular hole on the cantilever 1. By setting the support leg 3 and the cantilever 1 as a detachable connection structure, it is convenient to thread the cable. When threading the cable, the cable in the cantilever 1 can be penetrated into the support leg 3 and then the cantilever 1 and the support leg 3 can be connected, thereby making the operation of threading the cable more convenient.

[0037] The present utility model also provides a ladle car, as Figure 7 shown. The ladle car 8 is provided with the ladle car cable protection device as described above. By providing the ladle car cable protection device as described above on the ladle car 8, the ladle car cable can be effectively protected, avoiding the cable being burned by the falling molten steel and slag, reducing the waste of production resources, reducing the failure rate of the ladle car 8, and ensuring the production efficiency of the steel mill.

[0038] In summary, the cable protection device for the ladle car can be installed on the ladle car. The cable can pass through the channel on the cable inlet bracket into the cantilever and then enter the interior of the ladle car through the support leg, thereby protecting the cable, reducing the possibility of molten steel and slag falling on the cable, and extending the service life of the cable of the ladle car.
