Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a ladle support mechanism. Background Technology

[0002] Over the past few decades, with rapid industrialization, China has become one of the world's largest producers of castings, particularly in the field of cast steel, where its output growth has been remarkable. Cast steel parts, due to their excellent mechanical properties, are widely used in various industries such as automobiles, railways, shipbuilding, and machinery manufacturing. However, with the continuous expansion of market demand, traditional casting processes have gradually revealed their limitations, especially in the crucial step of molten steel pouring.

[0003] Traditional steel pouring typically relies on overhead cranes to hoist ladles containing molten steel from above into the pouring machine. While this method met early production needs to some extent, its problems have become increasingly apparent. First, overhead crane hoisting is inefficient, requiring considerable preparation time before each pour, thus limiting production efficiency. Second, due to the extremely high temperature of the molten steel (typically exceeding 1500℃), there are significant safety hazards during overhead crane hoisting; accidents could result in serious injuries and property damage.

[0004] Therefore, developing a more efficient and safer clamping mechanism is of great significance for improving the production efficiency of cast steel parts, ensuring operational safety, and improving product quality. Summary of the Invention

[0033] 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.

[0034] In this specification, identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings of this utility model, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions towards or away from a specific component, respectively. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Traditional ladle lifting methods involve using an overhead crane to hoist the ladle into the casting machine. However, improper operation or collisions with the casting machine during this process can easily lead to molten steel leakage and safety accidents. The ladle support mechanism provided in this application allows operators to work from the control room, away from the ladle, thus avoiding accidents and improving work efficiency. Furthermore, this application employs a support mechanism with its own positioning and signal transmission units, ensuring stable ladle operation and preventing molten steel leakage during the support process.

[0037] Figure 1 This diagram illustrates the structure of a steel ladle support mechanism provided in an exemplary embodiment of the present invention. Figure 2 This diagram illustrates the structure of the gripping arm of a ladle gripping mechanism according to an exemplary embodiment of the present invention. Figure 3 This diagram shows a partial structural schematic of the gripping end of the gripping arm of a ladle gripping mechanism provided in an exemplary embodiment of the present invention. Figure 4 A schematic diagram of the steel ladle structure of the steel ladle holding mechanism provided in an exemplary embodiment of the present invention is shown.

[0038] In detail, the above-mentioned ladle support mechanism includes a transverse carriage 1 and a support arm 2. The transverse carriage 1 is movably mounted on the lifting mechanism of the molten steel casting machine. The support arm 2 is hung on the transverse carriage 1 by at least one set of weighing sensors 3 for supporting the ladle 4. The support end 21 of the support arm 2 is connected to the support seat 41 of the ladle 4 through a positioning component 22.

[0039] In this embodiment, the transverse transfer carriage 1 is movably mounted on the lifting mechanism of the molten steel casting machine, and the lifting mechanism is mounted on the longitudinal transfer carriage, thereby enabling movement in the lateral, longitudinal, and vertical directions. It should be noted that the transverse transfer carriage 1 and the lifting mechanism do not participate in the weighing process and will not affect the weighing of the ladle 4.

[0040] Optionally, the number of load cells 3 can be flexibly adjusted according to the actual working conditions. In one example, there are four sets of load cells 3, which are evenly distributed at intervals at the connection between the grab arm 2 and the traverse vehicle 1.

[0041] It is worth mentioning that the two gripping ends 21 of the gripping arm 2 are L-shaped and are adapted to the support seats 41 symmetrically arranged on the ladle 4.

[0042] In some embodiments, please refer to Figure 3 The positioning component 22 includes at least one set of positioning posts 221; please refer to Figure 4 The support 41 has at least one set of positioning parts 42, and at least one set of positioning posts 221 are adapted to the at least one set of positioning parts 42. In one example, there are two sets of both positioning posts 221 and positioning parts 42.

[0043] Optionally, the positioning part 42 is one of a regular circular hole, square hole, elliptical hole, diamond hole, or keyway hole; or, the positioning part 42 is an irregular shaped hole.

[0044] Furthermore, the positioning post 221 has a guide portion 2211 that facilitates docking with the positioning part 42. In one example, the guide portion 2211 is tapered.

[0045] In some embodiments, the positioning component 22 further includes a signal transmission unit 222 for confirming that the positioning post 221 is properly aligned with the positioning part 42. In one example, the signal transmission unit 222 is a limit switch. In another example, the signal transmission unit 222 is a photoelectric switch. In industrial automation and control systems, detecting the position information of mechanical parts or objects is crucial. Limit switches and photoelectric switches are two commonly used sensors that can detect position information through contact and non-contact methods, respectively.

[0046] Next, the working principle of the steel ladle support mechanism involved in the embodiments of this utility model will be explained.

[0047] When the grab arm 2 moves to the position where the grab end 21 is below the support seat 41 with the cooperation of the transverse moving vehicle 1, the longitudinal moving vehicle and the lifting mechanism, the positioning column 221 is inserted into the positioning part 42 under the guidance of the guide part 2211 to achieve positioning docking; after the signal transmission part 222 receives the information that the positioning column 221 and the positioning part 42 are docked, it confirms that the positioning docking is completed, and then the ladle 4 can be moved.

[0048] In summary, this application provides a ladle-grabbing mechanism by movably mounting a transverse carriage on the lifting mechanism of a molten steel casting machine, and by using a grab arm with at least one set of weighing sensors mounted on the transverse carriage; wherein the grabbing end of the grab arm is connected to the ladle support seat via a positioning component. This provides a highly efficient, safe, and product-quality-improving ladle-grabbing mechanism.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
