Description

Technical Field

[0001] The utility model relates to the technical field of anode casting, and in particular to an automatic ladle changing device. Background Art

[0002] In the production process of electrolytic aluminum, the anode carbon block will be gradually consumed during the electrolysis process. After use, the residual anode carbon block needs to be separated from the aluminum guide rod, and the separated aluminum guide rod can be recycled.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0044] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] Reference Figure 1The utility model proposes an automatic ladle changing device, including a second sliding frame 16, which is slidably arranged on a bracket 1; a first rotating column 24 is rotatably arranged on the bracket 1, the first rotating column 24 is located on one side of the second sliding frame 16, and the rotating axis of the first rotating column 24 is perpendicular to the ground. After the second sliding frame 16 slides, it approaches or moves away from the first rotating column 24; a hanging member 21 is arranged on the first rotating column 24; there are two second hanging members 22, which are respectively arranged on both sides of the hanging member 21, and the second hanging members 22 are used to hook the ladle.

[0047] In this embodiment, the second sliding frame 16 can slide and adjust its position on the bracket 1 according to the actual needs of the production process, so that the pouring ladle can be accurately moved to the pouring position to achieve accurate pouring of liquid metal. This design is highly flexible and can adapt to the pouring needs of different workstations, reducing the time for changing positions and improving production efficiency.

[0048] The first rotating column 24 not only supports the hanging member 21, but also is the key to realize the automatic replacement of the ladle. Through the rotation of the first rotating column 24, the hanging member 21 moves accordingly, so that the second hanging bracket 22 can be accurately hooked with the ladle. This design avoids manual operation, reduces the operation risk, and ensures the smooth hooking and release of the ladle, thereby improving the operation safety.

[0049] The rotation of the first rotating column 24 allows the cast ladle to leave the second sliding frame 16 smoothly, while the second hanging frame 22 on the other side approaches and is ready to hook 29 a new ladle. This continuous action realizes the rapid replacement of the ladle without the need to transfer the molten metal by pouring or other complicated processes, thus simplifying the process and reducing the loss of the molten metal and the possible risk of contamination.

[0050] Furthermore, it also includes a first rotating frame 17, which is rotatably arranged relative to the second sliding frame 16, and the rotation axis of the first rotating frame 17 is parallel to the ground and perpendicular to the sliding direction of the second sliding frame 16; a first ladle 18 is arranged on the first rotating frame 17, and the first ladle 18 has a pouring port. After the first rotating frame 17 rotates, the first ladle 18 pours molten iron;

[0051] In this embodiment, the first ladle 18 is used to refer to the pouring ladle and the rotating ladle. When the first ladle 18 is on the second sliding frame 16, it is a pouring ladle, and when it moves toward the first rotating column 24, it is a transfer ladle. The first ladle 18 can not only achieve translation of the position on the second sliding frame 16 through the careful design of the first rotating frame 17, but also perform necessary rotation when necessary. This rotation function enables the first ladle 18 to tilt a certain angle at the right time point, ensuring that the molten iron can be poured into the anode smoothly and accurately, avoiding overflow or uneven distribution, and improving the accuracy and efficiency of casting.

[0052] The movement of the first rotating frame 17 is closely linked with the transfer, positioning, dumping and other steps of the first ladle 18, reflecting a high level of automated control. This not only reduces manual intervention, but also improves the safety of the operation and ensures the smoothness and efficiency of the entire operation process.

[0053] Furthermore, it also includes a first hanging bracket 19 which is arranged on the first rotating bracket 17 , and the first ladle 18 is rotatably arranged on the first rotating bracket 17 through the first hanging bracket 19 .

[0054] In this embodiment, the first hanger 19 can be dynamically connected and separated from the first ladle 18 quickly and safely by means of a motor drive or a telescopic device drive. This design ensures efficient docking of the ladle during transportation and pouring, reduces the need for manual operation, and improves the safety and efficiency of the operation.

[0055] Another implementation method is to achieve hooking with the first ladle 18 by lifting and lowering the hook member 21. This design more intuitively utilizes the height difference to achieve rapid hooking and releasing, reduces complex mechanical structures, and improves the stability and reliability of the system.

[0056] Furthermore, it also includes a first lifting member 20, which is lifted and set on the first rotating column 24, and the hanger 21 is set on the first rotating column 24 through the first lifting member 20; the first hanging plate 23 is set on the first ladle 18, and after the second sliding frame 16 slides, the first hanging plate 23 abuts against or moves away from the second hanging frame 22, and after the first lifting member 20 is lifted and lowered, the second hanging frame 22 drives the first ladle 18 away from or close to the first hanging frame 19.

[0057] In this embodiment, the second hanger 22 and the second hanger 22 adopt a lifting hook hanging method, which means that they can accurately dock with the first hanging plate 23 on the first ladle 18 through lifting actions, so as to achieve fast and safe hanging and release. This design reduces the complex operation in the hanging process, improves work efficiency, and reduces operational risks.

[0058] The lifting hook avoids direct manual operation, especially when handling high-temperature and heavy-loaded ladles, which greatly improves the safety of the working environment and reduces the risk of accidents caused by improper human operation.

[0059] The first hanging plate 23 adopts an inverted U-shaped design, which is not only convenient for overlapping with the lifting hanger and ensuring the stability of the hanging, but also this shape can naturally guide the dynamic balance of the first ladle 18 during the rotation process, reduce the friction and resistance during rotation, and make the rotation of the first ladle 18 smoother, avoiding the risk of shaking or overturning due to unstable hanging.

[0060] Furthermore, it also includes a third mobile frame 25, which is movably arranged on one side of the second sliding frame 16. After the third mobile frame 25 moves, it approaches or moves away from the first rotating column 24. The third mobile frame 25 is used to transport another first ladle 18 to the first rotating column 24. The second rotating frame 26 is rotatably arranged on the third mobile frame 25, and the rotation axis of the second rotating frame 26 is parallel to the rotation axis of the first rotating column 24. The second rotating frame 26 is provided with a first hanging frame 19.

[0061] In this embodiment, the third mobile frame 25, as a supplementary source for the first ladle 18, can deliver a new ladle full of liquid metal to the first rotating column 24, ensuring the continuity and efficiency of the pouring operation. Through the first rotating column 24, the used or empty ladle on the second sliding frame 16 can be quickly exchanged with the fully loaded first ladle 18 on the third mobile frame 25, reducing the idle travel time of the ladle to and from the smelting furnace and improving production efficiency.

[0062] The second rotating frame 26 is designed to further optimize the transfer process of the first ladle 18, especially when the first ladle 18 is on its way to the smelting furnace to receive liquid metal. By changing the direction of the first ladle 18 on the third mobile frame 25, the second rotating frame 26 can ensure that the first ladle 18 goes to the smelting furnace in the most reasonable or direct path, reducing turns or unnecessary moving distances, which not only saves time, but also reduces energy consumption and reduces the demand for working space.

[0063] Furthermore, it also includes a second rotating column 27, which is rotatably arranged on one side of the first rotating column 24, and the rotation axis of the second rotating column 27 is parallel to the axis of the first rotating column 24; a rotating rod 28 is rotatably arranged on the second rotating column 27, and the rotation axis of the rotating rod 28 is perpendicular to the axis of the second rotating column 27; a hook 29 is arranged at one end of the rotating rod 28, and the hook 29 is used to hook the ladle cover 31 of the first ladle 18. After the rotating rod 28 rotates, the hook 29 approaches or moves away from the first ladle 18 on the second hanger 22.

[0064] In this embodiment, a second rotating column 27 is provided on one side of the first rotating column 24, and a rotating rod 28 is rotatably arranged on the second rotating column 27. The rotating axis of the rotating rod 28 is perpendicular to the rotating axes of the first rotating column 24 and the second rotating column 27. Through the rotation of the second rotating column 27, the movement of the rotating rod 28 is more flexible and can adapt to different installation conditions.

[0065] One end of the rotating rod 28 has a hook 29, which is used to take and place the ladle cover 31. Through the precise control of the rotating rod 28, the hook 29 can be close to or away from the first ladle 18 at the appropriate time. When the hook 29 is in a low position, it can easily connect with the ladle cover 31, and then the ladle cover 31 is removed from or placed on the ladle through the lifting action of the rotating rod 28. This process is fully automated, reducing the complexity and danger of manual operation. Before the first ladle 18 is ready for pouring, the system automatically covers the first ladle 18, ensuring the temperature and purity of the metal solution inside the first ladle 18, while also providing safety protection for the working environment. After the pouring is completed, the automatic removal of the ladle cover 31 allows the first ladle 18 to easily enter the third mobile frame 25 to receive new metal solution. The whole process is smooth and efficient.

[0066] The hook 29 is designed to adopt two different hooking methods. One is to actively hook the ladle cover 31 through a driving mechanism. This method can respond quickly and is suitable for scenarios where the ladle cover 31 needs to be replaced quickly. The other is to rotate the ladle cover 31 itself into a predetermined position of the hook 29 and then be lifted by the hook 29. This method is gentler and suitable for situations where delicate operation is required to prevent damage to the ladle cover 31 or the sealing ring.

[0067] Furthermore, it also includes a second telescopic member 30, one end of which is hinged on the second rotating column 27, and the other end is hinged on the other end of the rotating rod 28. After the second telescopic member 30 is extended and retracted, the rotating rod 28 rotates.

[0068] In this embodiment, the first telescopic member 404 serves as a driving component between the rotating rod 28 and the second rotating column 27, which not only supports the weight of the rotating rod 28, but also ensures the stability of the rotating rod 28 during the lifting process through its precise telescopic action. This is very important for operating the ladle cover 31 with a certain weight, and can avoid damage to the ladle cover 31 or unstable operation caused by sudden or uneven movement.

[0069] Furthermore, the ladle cover 31 has a plurality of second through holes 3101, and also includes a plurality of pins 32, which are arranged on the first ladle 18, and the pins 32 correspond to the second through holes 3101 one by one, and the axis of the pins 32 is parallel to the axis of the first rotating column 24. After the ladle cover 31 is close to the first ladle 18, the pins 32 pass through the second through holes 3101.

[0070] In this embodiment, the first ladle 18 can be quickly installed and removed by plugging the pin 32 into the second through hole 3101. Compared with bolts or other fasteners, this connection method is simpler and faster to operate, reduces installation time, and improves production efficiency.

[0071] The close fit between the pin 32 and the second through hole 3101 ensures that during the pouring process, especially when pouring high-temperature molten metal, there will be no relative sliding between the ladle cover 31 and the first ladle 18, thereby avoiding safety accidents such as leakage of molten metal, injury to operators or fire caused by the sliding of the ladle cover 31, thereby ensuring the safety of the work site.

[0072] Furthermore, it also includes a sliding plate 33, which is slidably disposed on the second sliding frame 16, and the first rotating frame 17 is rotatably disposed on the sliding plate 33. After sliding, the sliding plate 33 moves away from or close to the part to be cast.

[0073] In this embodiment, the introduction of the sliding plate 33 allows the first rotating frame 17 to freely adjust its position in a two-dimensional plane, so that the pouring position of the first ladle 18 is more in line with the specific requirements of the production process.

[0074] Furthermore, it also includes a second lifting member 34 which is lifted and disposed on the sliding plate 33 , and the first rotating frame 17 is rotatably disposed on the sliding plate 33 through the second lifting member 34 .

[0075] In this embodiment, the second lifting member 34, the sliding plate 33 and the second sliding frame 16 work together to enable the second rotating frame 26 to be freely adjusted in three-dimensional space. The free adjustment capability in three-dimensional space enables the automated pouring system to more flexibly cope with various production scenarios, whether it is height changes, position changes or fine-tuning of the pouring angle, all can be easily achieved, thereby improving the adaptability of the system under different production requirements.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
