Technical Field

[0001] The utility model relates to the technical field of molten iron ladle transfer, and more specifically, to a splash-proof device for a molten iron transfer vehicle. Background Art

[0002] After the molten iron flows into the ladle, it needs to be lifted by a crane and placed on a transfer vehicle for transfer to the ingot casting process.

[0003] After searching the existing relevant patent: CN218855606U, a moving device is disclosed which is conducive to the stable transfer of the molten iron ladle. This prior art can lock and position the molten iron ladle on the transfer vehicle through the coordinated use of a positioning device and a clamping device, thereby ensuring the stability of the molten iron ladle during transfer, reducing the probability of shaking, and preventing safety hazards.

[0004] However, the inventors have discovered that the prior art has the following problems when in use: although the prior art clamps the molten iron ladle by a clamping device to prevent the ladle from shaking, when the transfer vehicle starts or stops, the molten iron ladle is heavy, so after the transfer vehicle stops, the molten iron inside the ladle will be subjected to a large reaction force, causing the molten iron to shake in the ladle and even splash out, affecting the stability of the ladle transfer. Therefore, the inventors have designed a splash-proof device for a molten iron transfer vehicle based on the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a splash-proof device for a molten iron transfer vehicle which reduces the reaction force exerted on the ladle when the transfer vehicle starts or stops, and avoids as much as possible the situation in which the molten iron in the ladle is shaken or even splashed due to a large reaction force exerted on the ladle.

DETAILED DESCRIPTION

[0022] See also Figure 1-3 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to an anti-splash device for a molten iron transfer vehicle, comprising a transfer vehicle 1 , wherein four guide rail wheels 2 are arranged at the bottom of the transfer vehicle 1 , so that the transfer vehicle 1 slides on the guide rails through the guide rail wheels 2 .

[0024] Specifically, a buffer tank 3 is provided on the transfer vehicle 1, a placement base 4 is provided in the buffer tank 3, the molten iron ladle is placed on the placement base 4, compression rods 7 are fixedly connected to the opposite side surfaces of the placement base 4, the compression rod 7 is arranged on one side of the travel direction of the transfer vehicle 1, and two compression chambers 8 are provided on the transfer vehicle 1, the other end of the compression rod 7 slides through the compression chamber 8, and one end of the compression rod 7 located in the compression chamber 8 is fixedly connected to a push plate 9, the push plate 9 slides in the compression chamber 8, and the side surface of the push plate 9 facing away from the compression rod 7 is in contact with the inner wall of the compression chamber 8 A compression spring 10 is fixedly connected between them. When the transfer vehicle 1 starts or stops transporting the molten iron ladle, the placement base 4 will slide in the buffer groove 3 due to the reaction force, so that the compression rod 7 pushes the push plate 9 to slide in the compression chamber 8. At the same time, the compression spring 10 is compressed or stretched. This method can reduce the reaction force on the molten iron ladle when the transfer vehicle 1 starts or stops, and try to avoid the situation where the molten iron in the ladle is shaken or even splashed due to a large reaction force, thereby ensuring the stability of the molten iron ladle during transportation.

[0025] Specifically, two buffer rubber blocks 5 are fixedly connected between the other two side surfaces of the placement base 4 and the inner wall of the buffer groove 3. At the same time, the buffer rubber block 5 is arranged on the side away from the driving direction of the transfer vehicle 1. Compression holes 6 are opened on the buffer rubber block 5. In this way, the setting of the buffer rubber block 5 further increases the buffering effect of the placement base 4.

[0026] Specifically, a plurality of supporting pulleys 11 are provided at the bottom of the placing base 4, and the bottom of the supporting pulley 11 is in contact with the bottom wall of the buffer tank 3, so that the supporting pulley 11 forms a supporting effect on the placing base 4. In this way, the problem that after the molten iron ladle is placed on the placing base 4, the placing base 4 is subjected to a greater gravity, resulting in increased friction between the placing base 4 and the bottom wall of the buffer tank 3 is avoided as much as possible, and the problem of the placing base 4 getting stuck is avoided.

[0027] Specifically, a bearing plate 12 is provided on the placing base 4, and the ladle is placed on the bearing plate 12. A reset groove 13 that matches the bearing plate 12 is opened on the placing base 4. The interior of the placing base 4 is hollow. A control rod 14 is fixedly connected to the lower end of the bearing plate 12. The lower end of the control rod 14 slides through the placing base 4. A limiting plate 15 is fixedly sleeved on the outer surface of the control rod 14 located in the placing base 4. A tension spring 20 is fixedly connected between the upper surface of the limiting plate 15 and the top wall of the placing base 4. The tension spring 20 is movably sleeved on the outer surface of the control rod 14. When the tension spring 20 is not affected by the tension force, the tension spring 20 will form a tension force on the limiting plate 15, so that the limiting plate 15 is close to the top of the placing base 4.

[0028] Specifically, the placement base 4 is provided with four control slides 16, and the four control slides 16 are arranged in a circular array with the reset groove 13 as the center point. The placement base 4 is provided with four connecting slides 17 that are all connected to the inside of the placement base 4. The lower sides of the four control slides 16 extend into the placement base 4 through the four connecting slides 17 respectively. A rotating plate 21 is hinged between the outer surface of the lower end of the control rod 14 and the control slide 16. An arc-shaped clamping plate 18 is fixedly connected to the surface of the control slide 16 on one side facing the reset groove 13, so When the ladle is placed on the supporting plate 12, the supporting plate 12 is stressed and moves downward. At this time, the control rod 14 will form a pulling force on the rotating plate 21, so that the rotating plate 21 pulls the control slide plate 16 to move to the side close to the reset groove 13. At the same time, the tension spring 20 is stretched, so that the arc-shaped clamping plate 18 contacts the outer surface of the ladle and clamps the ladle. In this way, the ladle can be automatically clamped when it is placed on the placement base 4, which reduces the operating steps of the staff and improves the transportation efficiency of the ladle.

[0029] Specifically, a limiting slide bar 19 is fixedly connected between the inner walls on both sides of the connecting slide groove 17, and the control slide plate 16 is slidably sleeved on the outer surface of the limiting slide bar 19. Therefore, the limiting slide bar 19 forms a limiting effect on the control slide plate 16, thereby avoiding the problem of tilting of the control slide plate 16 as much as possible.

[0030] The working principle of the splash-proof device of the molten iron transfer vehicle provided by the utility model is as follows: when the transfer vehicle 1 starts or stops transporting the molten iron ladle, the placement base 4 will slide in the buffer groove 3 due to the reaction force, so that the compression rod 7 pushes the push plate 9 to slide in the compression chamber 8, and the compression spring 10 is compressed or stretched at the same time.
