Description

Technical Field

[0001] This utility model relates to the field of molten iron ladle car technology, specifically an adjustable molten iron ladle car cover device. Background Technology

[0002] Molten iron ladle cars typically refer to special railway vehicles or in-plant transport vehicles specifically designed for transporting high-temperature molten iron, i.e., liquid pig iron. They are widely used in the iron and steel metallurgy industry. They are transport containers with thick refractory linings, resembling "torpedoes" or "large cylinders" in shape. They are used to collect molten iron from the blast furnace taphole and transport it to processes such as steelmaking converters or blast furnaces. Currently, most steel companies in China generally use open molten iron ladles to hold molten iron, placing the ladles on molten iron ladle cars and transporting them from the blast furnace to the steelmaking area by diesel locomotives or trucks.

[0003] The existing technology has the following defects or problems: The existing technology disclosed in CN219746313U is a ladle covering device for molten iron ladle cars, which belongs to the technical field of molten iron ladle car devices. The ladle covering device for molten iron ladle cars includes a car body. A placement groove is opened at the center of the upper surface of the car body. The molten iron ladle body is installed in the placement groove. Fixing blocks are fixed on both the left and right sides of the placement groove at the front and rear ends of the car body. The fixing blocks on the left and right sides of the placement groove are respectively grouped. A support frame is rotatably provided on the grouped fixing blocks. An electric push rod is rotatably provided on the bottom of the support frame away from the placement groove.

[0004] During the transportation of the molten iron ladle, the above-mentioned equipment covers the top of the ladle body, improving its sealing performance and reducing heat loss of the molten iron inside. At the same time, it can reduce the emission of harmful fumes from the ladle opening, improve the air environment, and facilitate the disassembly and installation of the insulation components inside the lid for regular maintenance. It is simple to operate and convenient to use.

[0005] The ladle capping device of the molten iron ladle car described above has a relatively simple cap structure with poor sealing performance. This makes it prone to rapid heat loss from the molten iron and the entry of external impurities into the ladle due to untimely or inaccurate manual operation. Frequent opening and closing of the cap can also cause jamming and delays, affecting the timeliness and accuracy of capping. Furthermore, during transportation, road bumps or sudden braking can cause the molten iron to splash out due to violent shaking, compromising its stability and safety.

[0006] Therefore, an adjustable iron ladle car cover device is proposed to solve the problems mentioned above. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides an adjustable lid-addressing device for molten iron ladle cars. This device solves the problems of jamming and delays that easily occur during frequent opening and closing of the lid, affecting the timeliness and accuracy of lid application. Furthermore, during transportation, road bumps or sudden braking can cause molten iron to splash out due to violent shaking, compromising stability and safety.

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a ladle body and a car body. A support plate is fixedly connected to the outside of the ladle body. A damping shaft is rotatably connected inside the support plate. An electric push rod is fixedly connected to the outer surface of the damping shaft. A connector is fixedly connected to the output end of the electric push rod. A cover is provided on the top of the ladle body. A mounting plate is fixedly connected to the upper surface of the cover. A connecting rod is fixedly connected to the upper surface of the mounting plate. A connecting shaft is rotatably connected to the other end of the connecting rod. The outer surface of the connecting shaft is connected to the connector. A fixed connection is provided, wherein a support rod is fixedly connected to the lower surface of the connecting rod, and a first fixed shaft is fixedly connected inside the support plate. The outer surface of the first fixed shaft is rotatably connected to the bottom end of the support rod. The output end of the electric push rod drives the connecting head to extend or retract, causing the connecting head to drive the connecting shaft to move. The connecting shaft then drives the connecting rod rotatably connected to it to rotate around the first fixed shaft as the rotation center. The bottom end of the support rod is rotatably connected to the first fixed shaft, providing support and a rotation fulcrum for the connecting rod. The connecting rod drives the mounting plate and cover fixed at the top to rotate synchronously, realizing the opening and closing of the cover.

[0009] Preferably, the vehicle body has a buffer groove inside, and a base is fixedly connected inside the buffer groove. Several fixing blocks are symmetrically fixedly connected inside the base. A limit rod is fixedly connected between each fixing block. A buffer spring is sleeved on the outside of the limit rod. Sliding sleeves are fixedly connected to both ends of the buffer spring. A rotating rod is rotatably connected to the upper surface of the sliding sleeve. The buffer plate drives the rotating rod to move through the concave block. The bottom end of the rotating rod pushes the sliding sleeve to slide on the limit rod, so that the buffer spring is compressed or stretched. The buffer spring absorbs and releases vibration energy through elastic deformation, further buffering the impact. The cooperation between the sliding sleeve and the limit rod ensures the stability of the buffer structure.

[0010] Preferably, a damper is fixedly connected to the upper surface of the fixed block, a buffer plate is fixedly connected to the output end of the damper, a concave block is fixedly connected to the lower surface of the buffer plate, and the concave block is rotatably connected to the other end of the rotating rod. The buffer plate slides downward in the buffer groove. When the buffer plate moves downward, it directly compresses the damper. The damper consumes vibration energy through its own damping characteristics, thus playing a preliminary shock absorption role.

[0011] Preferably, a second fixed shaft is fixedly connected inside the support plate, and at least two first fixed rings are fixedly connected to the outer surface of the second fixed shaft. An auxiliary spring is fixedly connected to the outside of the first fixed ring. The damping shaft can buffer the impact force when the electric push rod moves, keeping the operation smooth. During the opening and closing process, the auxiliary spring passes through the first fixed rings connected at both ends. The first fixed rings are fixed to the outside of the second fixed shaft, and the second fixed rings are fixed to the outside of the third fixed shaft, which plays an auxiliary support and buffering role for the rotation of the connecting rod.

[0012] Preferably, a third fixed shaft is fixedly connected inside the connecting rod, and a second fixed ring is fixedly connected to the outer surface of the third fixed shaft. The outer side of the second fixed ring is fixedly connected to the other end of the auxiliary spring.

[0013] Preferably, the upper surface of the buffer plate is fixedly connected to the bottom end of the molten iron ladle body, and the buffer plate is slidably connected inside the buffer trough.

[0014] Preferably, the sliding sleeve is slidably connected to the outer surface of the limiting rod by means of the buffer spring.

[0015] Compared with the prior art, this utility model provides an adjustable lid cover for molten iron ladle cars, which has the following advantages:

[0016] 1. By setting up an electric push rod, the connector head can drive the connecting rod to rotate, thereby opening or closing the cover through the cooperation of the connecting rod and the mounting plate. This realizes the automated opening and closing operation of the molten iron ladle car mouth, effectively replacing the traditional manual covering method. It not only reduces the labor intensity of operators, but also avoids the problem of excessive heat loss of molten iron and the entry of external impurities into the ladle due to untimely or inaccurate manual operation.

[0017] 2. By incorporating a buffer structure, the molten iron ladle body can effectively mitigate the impact force caused by road bumps or sudden braking during transportation, preventing molten iron from splashing out due to violent shaking. This buffer structure consists of multiple sets of buffer springs, rotating rods, and buffer plates located at the bottom of the molten iron ladle body. The cooperation between the buffer springs and the sliding sleeve can absorb most of the vertical vibration energy, while the damper can further attenuate the horizontal impact force, thereby improving the stability and safety of the molten iron ladle car during transportation.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 An adjustable molten iron ladle car cover device in this embodiment includes a molten iron ladle body 1 and a car body 12. A support plate 2 is fixedly connected to the outside of the molten iron ladle body 1. A damping shaft 3 is rotatably connected inside the support plate 2. An electric push rod 4 is fixedly connected to the outer surface of the damping shaft 3. A connector 5 is fixedly connected to the output end of the electric push rod 4. A cover 6 is provided on the top of the molten iron ladle body 1. An mounting plate 7 is fixedly connected to the upper surface of the cover 6. A connecting rod 8 is fixedly connected to the upper surface of the mounting plate 7. A connecting shaft 9 is rotatably connected to the other end of the connecting rod 8. The outer surface of the connecting shaft 9 is fixedly connected to the connector 5. A support rod 10 is fixedly connected to the lower surface of the connecting rod 8. A first fixed shaft 11 is fixedly connected inside the support plate 2. The outer surface of the first fixed shaft 11 is rotatably connected to the bottom end of the support rod 10.

[0027] The support plate 2 is internally fixedly connected to a second fixed shaft 23. At least two first fixed rings 24 are fixedly connected to the outer surface of the second fixed shaft 23. An auxiliary spring 25 is fixedly connected to the outside of the first fixed rings 24. The connecting rod 8 is internally fixedly connected to a third fixed shaft 26. A second fixed ring 27 is fixedly connected to the outer surface of the third fixed shaft 26. The outside of the second fixed ring 27 is fixedly connected to the other end of the auxiliary spring 25.

[0028] When the electric push rod 4 is activated, the output end of the electric push rod 4 drives the connector 5 to extend or retract, which in turn drives the connector 5 to move the connecting shaft 9. The connecting shaft 9 then drives the connecting rod 8, which is rotatably connected to it, to rotate around the first fixed shaft 11 as the rotation center. The bottom end of the support rod 10 is rotatably connected to the first fixed shaft 11, providing support and a rotation fulcrum for the connecting rod 8. The connecting rod 8 drives the mounting plate 7 and the cover 6, which are fixed at the top, to rotate synchronously, thereby opening and closing the cover 6.

[0029] At this time, the damping shaft 3 can buffer the impact force when the electric push rod 4 moves, keeping the action smooth. During the opening and closing process, the auxiliary spring 25 is connected to the first fixed ring 24 at both ends. The first fixed ring 24 is fixed to the outside of the second fixed shaft 23, and the second fixed ring 27 is fixed to the outside of the third fixed shaft 26. It plays an auxiliary support and buffering role for the rotation of the connecting rod 8, and improves the stability of the movement of the cover 6.

[0030] The vehicle body 12 has a buffer groove 13 inside. A base 14 is fixedly connected inside the buffer groove 13. Several fixed blocks 15 are symmetrically fixedly connected inside the base 14. A limit rod 16 is fixedly connected between each fixed block 15. A buffer spring 17 is sleeved on the outside of the limit rod 16. Sliding sleeves 18 are fixedly connected to both ends of the buffer spring 17. A rotating rod 19 is rotatably connected to the upper surface of the sliding sleeve 18. A damper 20 is fixedly connected to the upper surface of the fixed block 15. A buffer plate 21 is fixedly connected to the output end of the damper 20. A concave block 22 is fixedly connected to the lower surface of the buffer plate 21. The concave block 22 is rotatably connected to the other end of the rotating rod 19.

[0031] The upper surface of the buffer plate 21 is fixedly connected to the bottom end of the molten iron ladle body 1. The buffer plate 21 is slidably connected inside the buffer groove 13. The sliding sleeve 18 is slidably connected to the outer surface of the limiting rod 16 under the action of the buffer spring 17.

[0032] The weight and vibration of the bottom of the molten iron ladle 1 are transmitted to the buffer plate 21. The buffer plate 21 slides downward in the buffer groove 13. When the buffer plate 21 moves downward, it directly compresses the damper 20. The damper 20 consumes vibration energy through its own damping characteristics, playing a preliminary shock absorption role. On the other hand, the buffer plate 21 drives the rotating rod 19 to move through the concave block 22. The bottom end of the rotating rod 19 pushes the sliding sleeve 18 to slide on the limiting rod 16, so that the buffer spring 17 is compressed or stretched. The buffer spring 17 absorbs and releases vibration energy through elastic deformation, further buffering the impact.

[0033] The working principle of the above embodiment is as follows: When it is necessary to open or close the cover 6, the electric push rod 4 is activated, and the output end of the electric push rod 4 drives the connector 5 to extend and retract, so that the connector 5 drives the connecting shaft 9 to move. Then, the connecting shaft 9 drives the connecting rod 8, which is rotatably connected to it, to rotate around the first fixed shaft 11 as the rotation center. The bottom end of the support rod 10 is rotatably connected to the first fixed shaft 11, providing support and rotation fulcrum for the connecting rod 8. The connecting rod 8 drives the mounting plate 7 fixed at the top and the cover 6 to rotate synchronously, realizing the opening and closing of the cover 6.

[0034] Meanwhile, the damping shaft 3 can buffer the impact force when the electric push rod 4 moves, keeping the action smooth. During the opening and closing process, the auxiliary spring 25 is connected to the first fixing ring 24 at both ends. The first fixing ring 24 is fixed to the outside of the second fixing shaft 23, and the second fixing ring 27 is fixed to the outside of the third fixing shaft 26. This provides auxiliary support and buffering for the rotation of the connecting rod 8, improving the stability of the cover 6 movement.

[0035] The weight and vibration at the bottom of the molten iron ladle 1 are transmitted to the buffer plate 21. The buffer plate 21 slides downward in the buffer groove 13. When the buffer plate 21 moves downward, it directly compresses the damper 20. The damper 20 consumes vibration energy through its own damping characteristics, thus playing a preliminary shock absorption role.

[0036] On the other hand, the buffer plate 21 drives the rotating rod 19 to move through the concave block 22. The bottom end of the rotating rod 19 pushes the sliding sleeve 18 to slide on the limiting rod 16, so that the buffer spring 17 is compressed or stretched. The buffer spring 17 absorbs and releases vibration energy through elastic deformation, further buffering the impact. The cooperation between the sliding sleeve 18 and the limiting rod 16 ensures the stability of the buffer structure movement, and finally achieves a double buffering and shock absorption effect on the body of the molten iron ladle 1.

[0037] By setting a support plate 2 on the outside of the molten iron ladle body 1, the support plate 2 stabilizes the overall opening and closing operation of the cover 6. The car body 12 is used to transport the entire molten iron ladle body 1. Multiple fixing blocks 15 are fixed by the base 14, and the damper 20 is fixed inside the base 14 by the fixing blocks 15.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
