Description

Technical Field

[0001] This invention relates to the field of steelmaking technology, and in particular to a chassis component platform for use in molten iron ladle cars. Background Technology

[0002] The molten iron ladle car is used to place molten iron ladles, enabling the collection and transportation of molten iron from blast furnace ironmaking products. It is used in small and medium-sized blast furnaces. The molten iron ladle is cylindrical and supported on the car frame. A crane can be used to lift the molten iron ladle and tip the molten iron. In the existing technology, the "one ladle system" or "one ladle to the end" is generally adopted. It is a brand-new molten iron supply technology that has been developed in the steel industry in recent years. Its core technology is that the same molten iron ladle is used for blast furnace tapping and molten iron transportation, molten iron desulfurization in the steelmaking workshop, and molten iron addition to the converter.

[0003] However, existing molten iron ladles are supported on the frame of molten iron ladle cars by cast steel trunnions on both sides and limited by baffles. This structure does not provide sufficient fixation for the molten iron ladle, and the molten iron ladle is prone to loosening during transportation. Moreover, existing water tank cars have poor protective performance, and the molten iron ladle is easily affected by vibration during transportation. Therefore, this invention proposes a frame component platform for molten iron ladle cars to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a chassis component platform for molten iron ladle cars. This chassis component platform uses a grooved frame to hold the molten iron ladle. By moving a sliding plate along a groove, the distance between the support arm and the molten iron ladle can be changed, thereby adapting to molten iron ladles of different diameters. The clamping rod of the molten iron ladle can be locked in place by a slot on the support plate, thus serving as a three-point limit and fixation. In conjunction with a baffle plate blocking the molten iron ladle from the other side, it helps to improve the stability of the fixation.

These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0027] Example 1

[0028] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a vehicle frame component platform for molten iron ladle cars, including a groove frame 1 and a movable seat 2.

[0029] The groove frame 1 has a baffle 9 on the right side of its top, and a movable compartment 10 on the right side of the baffle 9. A protective plate 11 is movably installed inside the movable compartment 10, and a side protection component is provided on the left side of the protective plate 11. A bottom protection component is provided inside the groove of the groove frame 1. The groove frame 1 is mounted on a movable base 2, and a movable wheel 12 is rotatably installed under the movable base 2. In use, the molten iron ladle 34 is placed through the groove frame 1. The distance between the support arm 6 and the molten iron ladle 34 is changed by the sliding plate 4 moving along the slide 3 to accommodate molten iron ladles 34 of different diameters. The locking rod 35 of the molten iron ladle 34 can be locked by the slot 8 on the support plate 7, which is used for three-point limiting and fixing. The baffle 9 blocks the molten iron ladle 34 from the other side to improve the stability of the fixation. The fixed molten iron ladle 34 is lifted by the lifting component, and the sliding plate 4 is used to move it to the end. The molten iron ladle 34 is tilted by rotating the support arm 6, and the material can be unloaded without a crane.

[0030] A drive groove 13 is provided at the middle position of the top left side of the groove frame 1, and a first threaded screw 14 is rotatably installed inside the drive groove 13. The first threaded screw 14 is driven to rotate by a servo motor. The bottom of the slide plate 4 is provided with a nut block that matches the first threaded screw 14. In use, the first threaded screw 14 drives the slide plate 4 to move along the slide groove 3, changing the distance between the support arm 6 and the molten iron ladle 34. Alternatively, the slide plate 4 can be moved to the end, and the molten iron ladle 34 can be tilted to unload by rotating the support arm 6.

[0031] The lifting assembly includes a sleeve 15 and a lifting rod 16. The lifting rod 16 is movably inserted inside the sleeve 15. The bottom of the sleeve 15 has an inner chamber, and a first motor 17 is located inside the inner chamber. The output end of the first motor 17 has a second threaded screw 18, which extends into the lifting rod 16 and is threadedly fitted. In use, the first motor 17 drives the second threaded screw 18 to rotate, and the threaded action drives the lifting rod 16 to rise and fall within the sleeve 15. After the slot 8 on the support plate 7 can lock the locking rod 35 of the molten iron ladle 34, the fixed molten iron ladle 34 is raised.

[0032] A connecting shaft 19 connects the two sets of mounting bases 5. The two sets of support arms 6 are rotatably mounted to the mounting bases 5 via the connecting shaft 19. One end of the connecting shaft 19 is equipped with a gear 20, and the other end of the lifting rod 16 is equipped with a second motor 21. The output end of the second motor 21 is equipped with a worm gear 22, which is adapted to the gear 20. In use, the second motor 21 drives the worm gear 22 to rotate, the worm gear 22 drives the gear 20 to rotate, and the gear 20 drives the connecting shaft 19 to rotate, thereby driving the support arm 6 to rotate and tilting the molten iron ladle 34. Unloading can be done without a crane. The worm gear 22 also has a self-locking function.

[0033] The side protection assembly includes a protective chamber 23 and an elastic rod 24. The protective chamber 23 is located on the left side of the protective plate 11, and the elastic rod 24 is movably located inside the protective chamber 23 on the left side.

A third motor 27 is mounted at one end of the drive tube 26, and the output end of the third motor 27 is connected to the drive toothed roller. The right side of the protective plate 11 has meshing teeth that are compatible with the drive toothed roller. In use, one side of the molten iron ladle 34 is supported by the baffle 9. Through the action of the side protection assembly, the elastic rod 24, in conjunction with the first spring 25, dampens one side of the molten iron ladle 34. The third motor 27 drives the drive toothed roller to rotate, and the meshing teeth, in conjunction with the meshing teeth, drive the protective plate 11 to rise and fall within the movable chamber 10, which can also change the height of the side protection assembly to suit molten iron ladles 34 of different heights.

[0034] The groove frame 1 has an embedded groove 28 inside its groove. The bottom protection assembly includes a second spring 29 and an arc plate 30. The second spring 29 is located inside the embedded groove 28, and the arc plate 30 is located above the second spring 29, adapting to the embedded groove 28. In use, the arc plate 30, in conjunction with the second spring 29, provides shock absorption to the molten iron ladle 34 from the bottom.

[0035] The top of the movable seat 2 is provided with a T-slot 31, and both sides of the bottom of the groove frame 1 are provided with T-blocks 32. The T-blocks 32 are adapted to the T-slots 31, and a third spring 33 connects the lower end of the T-blocks 32 to the bottom of the T-slots 31. In use, the adaptation of the T-slots 31 and the T-blocks 32, combined with the action of the third spring 33, provides overall shock absorption for the groove frame 1, which is beneficial for all-round protection of the molten iron ladle 34.

[0036] The groove of the groove frame 1 is used to place the molten iron ladle 34. Both ends of the molten iron ladle 34 are provided with locking rods 35, which are adapted to the locking grooves 8. In use, the molten iron ladle 34 is placed through the groove frame 1. The distance between the support arm 6 and the molten iron ladle 34 is changed by moving the slide plate 4 along the slide groove 3 to accommodate molten iron ladles 34 of different diameters. The locking rods 35 of the molten iron ladle 34 can be locked by the locking grooves 8 on the support plate 7, which serves as a three-point limit and fixation.

[0037] Example 2

[0038] according to Figure 1 , 6 As shown, this embodiment proposes a vehicle frame component platform for molten iron ladle cars, including a groove frame 1 and a movable seat 2. Both ends of the top left side of the groove frame 1 are provided with slide grooves 3, and slide plates 4 are movably mounted on the slide grooves 3 via sliders. Both ends of the slide plates 4 are provided with lifting components, and both sets of lifting components are provided with mounting seats 5. The mounting seats 5 are rotatably provided with support arms 6, and the right side of the support arms 6 is provided with a support plate 7. The support plate 7 is provided with a slot 8.

[0039] The groove frame 1 has a baffle 9 on the right side of its top, and a movable compartment 10 on the right side of the baffle 9. A protective plate 11 is movably installed inside the movable compartment 10, and a side protection component is provided on the left side of the protective plate 11. A bottom protection component is provided inside the groove of the groove frame 1. The groove frame 1 is mounted on a movable base 2, and a movable wheel 12 is rotatably installed under the movable base 2. In use, the molten iron ladle 34 is placed through the groove frame 1. The distance between the support arm 6 and the molten iron ladle 34 is changed by the sliding plate 4 moving along the slide 3 to accommodate molten iron ladles 34 of different diameters. The locking rod 35 of the molten iron ladle 34 can be locked by the slot 8 on the support plate 7, which is used for three-point limiting and fixing. The baffle 9 blocks the molten iron ladle 34 from the other side to improve the stability of the fixation. The fixed molten iron ladle 34 is lifted by the lifting component, and the sliding plate 4 is used to move it to the end. The molten iron ladle 34 is tilted by rotating the support arm 6, and the material can be unloaded without a crane.

[0040] The groove of the groove frame 1 is used to place the molten iron ladle 34. Both ends of the molten iron ladle 34 are provided with locking rods 35, which are adapted to the locking grooves 8. In use, the molten iron ladle 34 is placed through the groove frame 1. The distance between the support arm 6 and the molten iron ladle 34 is changed by moving the slide plate 4 along the slide groove 3 to accommodate molten iron ladles 34 of different diameters. The locking rods 35 of the molten iron ladle 34 can be locked by the locking grooves 8 on the support plate 7, which serves as a three-point limit and fixation.

[0041] At the midpoint of each end of the groove frame 1, there is a rotating chamber 36, and an elliptical disk 37 is rotatably mounted inside the rotating chamber 36. The outer side of the elliptical disk 37 is covered with a brake pad. A fourth motor 38 is located on the outer side of the rotating chamber 36, and the output end of the fourth motor 38 is connected to the elliptical disk 37. When not in use, the fourth motor 38 can drive the elliptical disk 37 to rotate, so that the longer end of the elliptical disk 37 contacts the lower ground, and the brake pad is used for braking to prevent the device from shifting.

[0042] The platform for the molten iron ladle car uses a grooved frame 1 to hold the molten iron ladle 34. The sliding plate 4 moves along the slide 3 to change the distance between the support arm 6 and the molten iron ladle 34, thus adapting to molten iron ladles 34 of different diameters. The slot 8 on the support plate 7 can hold the locking rod 35 of the molten iron ladle 34, which is used for three-point limiting and fixing. With the help of the baffle 9, the molten iron ladle 34 is blocked from the other side, which helps to improve the stability of the fixing. The fixed molten iron ladle 34 can be lifted by the lifting component, moved to the end by the sliding plate 4, and tilted by the rotation of the support arm 6, so that the material can be unloaded without a crane. It has multiple functions. Meanwhile, the baffle 9 supports one side of the molten iron ladle 34. Through the side protection component, the elastic rod 24, in conjunction with the first spring 25, dampens one side of the molten iron ladle 34. The height of the side protection component can be adjusted by raising and lowering the protective plate 11 within the movable chamber 10, accommodating molten iron ladles 34 of different heights. Furthermore, through the bottom protection component, the arc plate 30, in conjunction with the second spring 29, dampens the molten iron ladle 34 from the bottom. Combined with the adaptation of the T-slot 31 and T-block 32, and the action of the third spring 33, the entire groove frame 1 is damped, providing comprehensive protection for the molten iron ladle 34 and preventing vibration impact. Additionally, when not in use, the fourth motor 38 can drive the elliptical disk 37 to rotate, causing the longer end of the elliptical disk 37 to contact the ground below, where brake pads are used for braking to prevent displacement of the device.
