Description
Technical Field
[0001] This utility model relates to the field of casting equipment technology, specifically a multi-functional ladle transfer vehicle for molten iron in casting based on chain drive. Background Technology
[0002] In the molten iron transfer process in the foundry industry, the existing equipment generally uses ball screw drive for the lifting mechanism.
[0003] However, ball screw drive structures have many adaptability defects: on the one hand, they are extremely sensitive to pollutants such as high-temperature metal dust, sand, and slag in the foundry workshop. Splashing molten iron or sand intrusion can easily cause the screw to jam or wear, seriously affecting the normal operation of the equipment. On the other hand, in harsh environments, frequent cleaning and maintenance are required 2-3 times a month, which not only increases labor costs but also causes significant production losses due to frequent downtime. In addition, high-precision ball screws are prone to deformation in the vibration environment of the workshop, directly affecting the lifting and positioning accuracy. Heavy-duty ball screws that meet the requirements of large specifications and high loads also have problems such as high cost and long ordering cycles, making it difficult to meet the high-efficiency and stable requirements of casting production.

[0031] The lifting assembly 8 includes a housing 9, inside which a main frame 10 is fixedly installed.

Bearing seats 25 are provided at both output ends of the geared motor 24. Drive sprockets 13 are fixedly installed at both output ends of the geared motor 24 through the bearing seats 25. The two drive sprockets 13 are respectively connected to the two driven sprockets 11 located above by a first chain 12. A bracket 26 and a counterweight assembly 14 are provided between the two first chains 12.
[0032] Example 2: The difference between this example and Example 1 is that the bracket 26 is provided with a spherical bag 27, and two sets of connecting blocks 16 are fixedly installed on the surface of the bracket 26. The two connecting blocks 16 located at the top are fixedly connected to one end of the two first chains 12.
[0033] Example 3: The difference between this example and Example 1 is that the counterweight assembly 14 includes a counterweight block 15. A set of fixing blocks 23 are fixedly installed on the upper and lower surfaces of the counterweight block 15. The two upper fixing blocks 23 are fixedly connected to the other ends of the two first chains 12. The two lower fixing blocks 23 are fixedly connected to the two lower connecting blocks 16 with second chains 17. The two second chains 17 are respectively engaged with the two lower driven sprockets 11.
[0034] Example 4: The difference between this example and Example 1 is that guide rails 18 are fixedly installed on both sides and the back of the main frame 10, and guide bearings 19 are provided on both sides of the bracket 26 and the counterweight 15.

[0039] Example 9: The difference between this example and Example 1 is that a weighing sensor 22 is installed on the trolley 1 to monitor the weight of the molten iron in the spheroidizing ladle 27 in real time.
[0040] In summary, the control methods, detailed connection methods, and usage methods of the electrical components of this chain-driven multi-functional ladle transfer vehicle for molten iron in casting are well-known technologies in the field. Those skilled in the art can connect all electrical components and their compatible power supplies through wires, and should select appropriate controllers according to actual conditions to meet control requirements. The detailed connection methods and control schemes are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0041] When loading molten iron, the main trolley 1 is driven by a reducer to move its steel wheels left and right on the track. The moving trolley 3 is driven by a reducer to move back and forth on the steel rails of the fixed base frame 2, so that the spheroidizing ladle 27 is aligned with the tap hole of the furnace. After loading, the reduction motor 24 of the lifting assembly 8 drives the drive sprocket 13 on the bearing seat 25 to rotate. The drive sprocket 13 drives the driven sprocket 11 above through the first chain 12. Since the connecting block 16 above the bracket 26 is fixed to one end of the first chain 12, and the fixing block 23 above the counterweight block 15 of the counterweight assembly 14 is fixed to the other end of the first chain 12, and the fixing block 23 below the counterweight block 15 is connected to the connecting block 16 below the bracket 26 through the second chain 17 to form a closed loop, the bracket 26 and the counterweight block 15 achieve smooth lifting and lowering along the guide rail 18 of the main frame 10 through the guide bearing 19. During transfer, the main trolley 1 and the moving trolley 3 move to the target position again. If the direction needs to be adjusted, the slewing reduction motor 5 of the slewing bearing assembly 4 is activated. The slewing bearing 7 on the gear internal meshing drive mounting frame 6 rotates, driving the lifting assembly 8 to rotate. When pouring molten iron, the movable ladle cover 21 is opened, and the lifting and rotation angles are finely adjusted to align the spheroidizing ladle 27 with the mold. After completion, the equipment is reset and ready for the next cycle. This utility model uses chain drive instead of ball screw, which is resistant to dust and slag, reduces jamming and wear, reduces maintenance frequency and downtime losses, and has a lower cost than heavy-duty ball screws with a shorter procurement cycle. The counterweight assembly 14 is adjustable in weight, reducing the load on the geared motor 24. Together with the guide rail 18 and guide bearing 19, it improves lifting stability and positioning accuracy. The chain is not easily deformed in a vibration environment. It integrates functions such as left and right movement of the trolley 1, forward and backward movement of the trolley 3, rotation of the slewing bearing assembly 4, lifting, and monitoring by the weighing sensor 22, making it flexible and adaptable to multiple scenarios. The counterweight block 15 and the bracket 26 form a closed loop through the chain to avoid jamming, and the movable ladle cover 21 ensures safety. It is suitable for molten iron transfer in high-temperature, dusty casting workshops.
