Description

Technical Field

[0001] This utility model relates to the field of steelmaking technology, and in particular to a cable conductor device for a ladle car. Background Technology

[0002] Ladle cars are widely used in industries such as manufacturing, metallurgy, and steel. They are indispensable equipment in steel plants for transporting molten steel ladles. After receiving the molten steel ladle, the ladle car enters the bottom of the LF refining furnace to begin refining and steelmaking. After completion, it moves to the molten steel receiving span for capping, and then onto the continuous casting machine to cast billets. It is a crucial connecting piece of equipment on the production line. After LF refining and steelmaking, the ladle car receives the molten steel and transports it to the continuous casting machine to cast billets. Due to the special nature of the material transported by the ladle car, the temperature is higher than in other operating conditions. The stability of its operation is crucial to ensuring the success of the next process, and the proper functioning of the ladle car's drum cable is an important factor in its stable operation.

[0003] When the ladle car enters the station to process the molten steel, the cable reel is just pulled flat and positioned above the conductor. Figure 1 If the molten steel reacts violently during refining, resulting in severe slag splashing, the slag will adhere to the cable's protective layer, potentially burning the cable and causing irreversible damage. Even during normal refining, a small amount of slag will adhere to the cable, accumulating over time and increasing its load. When the cable sways as it travels alongside the ladle car, this can cause tearing or damage to the cable's protective layer. Therefore, it is crucial to ensure the cable guide is securely installed and accurately positioned, and to promptly remove any adhering slag. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cable conductor device for a ladle car, which prevents steel slag from burning the cable, protects the cable, and extends its service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable conductor device for a ladle car includes a protective frame, a conductor tube, and a shielding tube. The protective frame is a hollow structure with openings at both ends. One side of the protective frame is disposed on the side of the ladle car and is connected to the ladle car. A connecting plate is disposed on the side of the protective frame away from the ladle car, and the connecting plate is provided with a lead-in port connected to the protective frame.

[0007] The conductor tube and the shielding tube are arranged vertically on the connecting plate, with the conductor tube located below the shielding tube. The conductor tube is a tubular structure with open ends, and one end of the conductor tube is fixedly connected to the connecting plate and communicates with the lead-in port. A through-hole is provided on the side of the conductor tube near the shielding tube so that the cable of the ladle car passes through the protective frame into the conductor tube and is led out through the through-hole.

[0008] Furthermore, the protective frame has mounting edges welded around its perimeter on the side away from the connecting plate, and these mounting edges are connected to the ladle car by first bolts.

[0009] Furthermore, a fixing clamp is provided inside the conductor tube. The fixing clamp is located on the inner wall of the side adjacent to the conductor opening. First screws are fixedly provided at both ends of the inner wall of the conductor tube. Mounting holes are provided on both sides of the fixing clamp. The fixing clamp is sleeved on the outside of the first screw through the mounting holes, and the first screw is threaded with a first nut to clamp the cable of the ladle car between the fixing clamp and the inner wall of the conductor tube.

[0010] Furthermore, a baffle is provided at the end of the wire tube away from the connecting plate.

[0011] Furthermore, the baffle is connected to the end face of the wire tube on both diagonal sides by second bolts to seal the opening of the wire tube.

[0012] Furthermore, a protective plate is provided on the side of the shielding cylinder facing away from the conductor cylinder, and the protective plate is fixedly connected to the shielding cylinder.

[0013] Furthermore, a connector is provided at the bottom of the protective plate. One side of the connector is fixedly connected to the protective plate, and the other side is an arc-shaped structure that fits the shielding cylinder. The connector is provided with a second screw. One end of the second screw is connected to the connector, and the other end passes through the shielding cylinder. The second screw is threaded with a second nut to fix the connector on the shielding cylinder.

[0014] The beneficial effects of this utility model are:

[0015] 1. The cable of the ladle car is sequentially threaded through the protective frame and the conductor tube before exiting through the cable outlet. The original conductor guide is used as a shield. Simultaneously, the protective frame and conductor tube effectively shield the cable from molten steel during ladle car processing, preventing slag buildup on the cable, reducing cable load, and protecting the cable from slag burn. The original conductor guide was installed higher than the ladle platform, offering virtually no protection. This new design lowers the conductor tube height by 800mm, allowing the existing conductor guide to be used as a cable stop. This reduced height also facilitates routine maintenance and inspection, leading to more stable equipment operation.

[0016] 2. The protective plate further protects the cable from molten steel splashing onto the cable near the conductor drum. The protective plate and shielding cylinder are detachable structures, which can be removed during ladle car maintenance to avoid affecting the maintenance of the ladle car.

[0023] Please also see Figure 1 and Figure 2 The preferred embodiment of the present invention provides a cable conductor device for a ladle car, comprising a protective frame 1, a conductor tube 2, and a shielding tube 3.

[0024] The protective frame 1 is a hollow structure with openings at both ends. One side of the protective frame 1 is set on the side of the ladle car and is connected to the ladle car. A connecting plate 11 is set on the side of the protective frame 1 away from the ladle car. The connecting plate 11 is provided with a lead-in port 111 that is connected to the protective frame 1.

[0025] like Figure 1 As shown, the protective frame 1 has mounting edges 12 welded around its perimeter on the side away from the connecting plate 11, and the mounting edges 12 are connected to the ladle car by the first bolt 121.

[0026] The conductor tube 2 and the shielding tube 3 are arranged on the connecting plate 11 in the vertical direction, and the conductor tube 2 is located below the shielding tube 3. The conductor tube 2 is a tubular structure with open ends, and one end of the conductor tube 2 is fixedly connected to the connecting plate 11 and communicates with the lead wire port 111. A through conductor port 201 is provided on the side of the conductor tube 2 near the shielding tube 3 so that the cable of the ladle car passes through the protective frame 1, enters the conductor tube 2, and is led out through the conductor port 201.

[0027] The cable of the ladle car is sequentially threaded through the protective frame 1 and the conductor tube 2, and then led out through the cable outlet 201. The original conductor guide is used as a shield tube 3. Simultaneously, the protective frame 1 and conductor tube 2 effectively shield the molten steel entering the ladle car for processing, preventing slag accumulation on the cable, reducing the cable load, and protecting the cable from slag burn-out. The original conductor guide was installed higher than the ladle platform, offering virtually no protection. This new design lowers the height of the conductor tube 2 by 800mm, allowing the existing conductor guide to be used as a stop to protect the cable. This reduced height also facilitates daily maintenance and inspection, resulting in more stable equipment operation.

[0028] like Figure 2 As shown, a fixing clamp 21 is provided inside the conductor tube 2. The fixing clamp 21 is located on the inner wall of one side adjacent to the conductor opening 201. A first screw 22 is fixedly provided at both ends of the inner wall of the conductor tube 2. Mounting holes are provided on both sides of the fixing clamp 21. The fixing clamp 21 is sleeved on the outside of the first screw 22 through the mounting holes, and the first screw 22 is threaded with a first nut 221 to clamp the cable of the ladle car between the fixing clamp 21 and the inner wall of the conductor tube 2.

[0029] In this embodiment, the fixing clamp 21 is arranged along the axial direction of the conductor tube 2. The fixing clamp 21 can fix the cable of the ladle car inside the conductor tube 2, so as to avoid the cable end being pulled during the movement of the ladle car, and can facilitate the cable to be led out of the conductor tube 2 through the conductor port 201.

[0030] like Figure 1 As shown, a baffle 4 is provided at the end of the conductor tube 2 away from the connecting plate 11.

[0031] The baffle 4 is connected to the end face of the conductor cylinder 2 on both diagonal sides by the second bolt 41 to seal the opening of the conductor cylinder 2. The conductor cylinder 2 is provided with a connecting block 23. The second bolt 41 passes through the connecting block 23 and is fixed by a nut to fix the baffle 4 to the outside of the conductor cylinder 2, so as to prevent steel slag or other foreign objects from entering the conductor cylinder 2 and causing damage to the cable.

[0032] like Figure 1 and Figure 2 As shown, a protective plate 5 is provided on the side of the shielding cylinder 3 facing away from the conductor cylinder 2, and the protective plate 5 is fixedly connected to the shielding cylinder 3.

[0033] The bottom of the protective plate 5 is provided with a connector 51. One side of the connector 51 is fixedly connected to the protective plate 5, and the other side is an arc-shaped structure that fits with the shielding cylinder 3. The connector 51 is provided with a second screw 52. One end of the second screw 52 is connected to the connector 51, and the other end passes through the shielding cylinder 3. The second screw 52 is threaded with a second nut 521 to fix the connector 51 on the shielding cylinder 3.

[0034] In this embodiment, the shielding cylinder 3 has a through-hole on the side facing away from the wire cylinder 2. After the second screw 52 passes through the mounting hole, tightening the second nut 521 can fix the connector 51 on the shielding cylinder 3. At the same time, since the connector 51 fits into the shielding cylinder 3, the protective plate 5 remains fixed and will not rotate relative to the shielding cylinder 3.

[0035] The protective plate 5 further protects the cable from molten steel splashing onto the cable near the conductor cylinder 2. The protective plate 5 and the shield cylinder 3 are detachable structures, which can be disassembled during the maintenance of the ladle car to avoid affecting the maintenance of the ladle car.

[0036] In this embodiment, the protective plate 5 has edges on both sides to prevent molten steel from flowing down the sides of the protective plate 5, thus further improving the protective effect. When it is necessary to remove the slag inside the protective plate 5, the protective plate 5 can be disassembled.
