[0002] In industries such as steel production, molten iron ladle cars are crucial equipment for transporting molten iron. During transportation, the molten iron ladle needs to be insulated to ensure its temperature meets the requirements of subsequent processes.

[0003] Traditional ladle cover structures for molten iron ladle cars are cumbersome to install and disassemble, inconvenient for maintenance and replacement, and those using mechanical structures suffer from poor linkage, complex structures, and high maintenance costs, making them unsuitable for the demands of modern industrial production. Therefore, developing a convenient and highly interconnected linkage structure for molten iron ladle car covers is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the traditional molten iron ladle car cover structure in the prior art, which is cumbersome to install and disassemble and inconvenient to repair and replace, and to propose a molten iron ladle car cover linkage structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ladle cover linkage structure for a molten iron ladle car includes a molten iron car body, wherein a molten iron ladle for containing molten iron is provided inside the molten iron car body. In order to maintain the temperature of the molten iron in the ladle, two heat-insulating covers are provided on the upper side of the ladle. The two heat-insulating covers are spliced ​​together to form a cover body for sealing the molten iron ladle. Both sides of the top of the molten iron car body are fixed with base plates by bolts. Each of the two base plates is equipped with a set of flipping components. The two sets of flipping components are used to drive and control the opening or closing of the two heat preservation covers.

[0006] In one possible design, each set of the flipping components includes two drive units fixed to the base plate, two flip rods welded to the surface of the heat insulation cover, two fixing frames welded to the top of the base plate, a common rotating shaft rotating within the two fixing frames, two flip rods welded to the surface of the rotating shaft, two connecting rods welded to the surface of the rotating shaft, the two connecting rods located below the two flip rods, a sliding groove provided within each of the two connecting rods, a common adjusting rod sliding within the two sliding grooves, and a set of connecting components provided between the output ends of the two drive units and the adjusting rods. Specifically, by activating two drive units, the adjusting rod is moved. When the adjusting rod moves, it slides in two grooves. The adjusting rod drives two connecting rods to rotate around the surface of the rotating shaft. The two connecting rods drive the rotating shaft to rotate. The rotating shaft drives the insulation cover to rotate and open through two flip rods. Conversely, it can drive the insulation cover to close.

[0007] In one possible design, each set of the connecting components includes two connecting blocks fixed to the surface of the adjusting rod, and the output end of the drive unit is fixedly connected to the two connecting blocks by bolts; This design allows for easy separation and connection of the drive unit and the adjustment rod.

[0008] In one possible design, the drive unit is a hydraulic cylinder.

[0009] In one possible design, the drive unit can also be a cylinder.

[0010] In one possible design, both of the insulation covers are made of carbon steel.

[0011] In this application, the adjusting rod is moved by activating two drive units. When the adjusting rod moves, it slides in two slide grooves. The adjusting rod drives two connecting rods to rotate around the surface of the rotating shaft. The two connecting rods drive the rotating shaft to rotate. The rotating shaft drives the heat insulation cover to rotate and open through two flip rods. Conversely, it can drive the heat insulation cover to close.

[0012] Beneficial effects: In this utility model, the ladle cover linkage structure of the molten iron ladle car can simultaneously drive two heat preservation covers to open or close by setting two sets of flipping components, realizing the automated operation of the heat preservation covers, greatly reducing labor intensity, improving work efficiency, and avoiding the safety hazards caused by manual operation in high temperature environment. In this utility model, the ladle cover linkage structure of the molten iron ladle car has a drive component in the tilting assembly connected to the adjusting rod through a connecting component. The connection method is simple and reliable, and it is convenient to disassemble and connect, which facilitates the maintenance and repair of the equipment and reduces maintenance costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figures 1-4 A ladle cover linkage structure for a molten iron ladle car, applied in the field of linkage equipment technology, includes a molten iron car body 1, with an internal space for accommodating a molten iron ladle 2, within which the molten iron ladle 2 is placed. To maintain the temperature of the molten iron inside the ladle 2, two heat-insulating covers 6 are installed on the upper side of the ladle 2, the two heat-insulating covers 6 being joined together to form a cover body, achieving a sealing of the molten iron ladle 2. Base plates 10 are bolted to both sides of the top of the molten iron car body 1, and each of the two base plates 10 has a set of tilting components, which drive the opening or closing of the two heat-insulating covers 6.

[0017] Each set of flipping components includes two drive units 7 fixed to the base plate 10. In this embodiment, the drive units 7 are hydraulic cylinders, but pneumatic cylinders can also be used. Two flipping rods 5 are welded and fixed to the surface of the heat insulation cover 6, and two fixing frames 3 are welded and fixed to the top of the base plate 10. The same rotating shaft 4 is rotatably installed in the two fixing frames 3. The two flipping rods 5 are welded and fixed to the surface of the rotating shaft 4, and two connecting rods 8 are welded and fixed to the surface of the rotating shaft 4. The two connecting rods 8 are located below the two flipping rods 5, and each of the two connecting rods 8 has a sliding groove 12. The same adjusting rod 9 is slidably installed in the two sliding grooves 12. A set of connecting components is provided between the output end of each of the two drive units 7 and the adjusting rod 9.

[0018] During operation, the two drive units 7 are activated, pushing the adjusting rod 9 to move. As the adjusting rod 9 moves, it slides within the two sliding grooves 12, driving the two connecting rods 8 to rotate around the surface of the rotating shaft 4. The two connecting rods 8 drive the rotating shaft 4 to rotate, and the rotating shaft 4, through the two flip rods 5, drives the insulation cover 6 to rotate, thus opening the insulation cover 6; conversely, if the drive units 7 move in the opposite direction, they can drive the insulation cover 6 to close.

[0019] In another embodiment: Refer to Figures 1-4An improvement upon Embodiment 1 is made: each connecting assembly includes two connecting blocks 11 fixed to the surface of the adjusting rod 9, and the output end of the drive unit 7 is fixedly connected to the two connecting blocks 11 by bolts. This connection method facilitates the disassembly and connection of the drive unit 7 and the adjusting rod 9.

[0020] Both insulation covers 6 are made of carbon steel, which has good strength and heat resistance, and can meet the usage requirements of the insulation covers 6.

[0021] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
