Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying anything.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0028] Example 1, please refer to Figures 1 to 3 This utility model provides a technical solution: a lead alloy smelting apparatus, including a smelting furnace 17, with a feed inlet 19 on the top wall of the smelting furnace 17 and a discharge outlet 18 on one side wall of the upper part of the smelting furnace 17. The lead alloy smelting apparatus also includes a base 1, two upright plates 2, and a tilting component. The smelting furnace 17 is placed on the base 1, and the two upright plates 2 are fixedly installed on the base 1, with the two upright plates 2 located on opposite sides of the base 1.
[0029] A first shaft 15 and a second shaft 16 are symmetrically fixed on both outer side walls of the smelting furnace 17. The first shaft 15 is located near the discharge port 18, and the second shaft 16 is located away from the discharge port 18.
[0030] The tipping mechanism includes two front drive assemblies and two rear drive assemblies. The two front drive assemblies are respectively mounted on two upright plates 2, and the two rear drive assemblies are also respectively mounted on two upright plates 2. The front drive assemblies are drivenly connected to the first shafts 15, and the two front drive assemblies drive the two first shafts 15 to rise or fall synchronously. The rear drive assemblies are drivenly connected to the second shafts 16, and the two rear drive assemblies drive the two second shafts 16 to rise or fall synchronously. A first collar 13 is fitted on the outer wall of the first shaft 15, and the two are rotatably connected. A second collar 14 is fitted on the outer wall of the second shaft 16, and the two are slidably connected.
[0031] The base 1 and two uprights 2 provide support. The tilting component drives the smelting furnace 17 to move up and down and tilts the entire furnace during this movement, facilitating the pouring of the molten lead alloy inside. Two front drive components synchronously drive the front end of the smelting furnace 17 (the end closest to the discharge port 18) to rise or fall. Two rear drive components synchronously drive the rear end of the smelting furnace 17 (the end furthest from the discharge port 18) to rise or fall. After the tilting component drives the smelting furnace 17 to rise, the rear end of the smelting furnace 17 continues to rise via the two rear drive components, causing the rear end of the smelting furnace 17 to move upward relative to the front end, tilting the entire smelting furnace 17 and facilitating the pouring of the molten lead alloy. The second ring 14 is flat, and its internal slide has a certain length, providing clearance for the second shaft 16, allowing for lateral displacement of the second shaft 16 when the smelting furnace 17 tilts. When the smelting furnace 17 tilts, it rotates locally by a certain angle around the first shaft 15. The first and second rings 13 and 14 provide stable support for the smelting furnace 17. During the rising and tilting process of the smelting furnace 17, the first and second rings 13 and 14 cooperate with the first and second shafts 15 and 16 respectively, effectively distributing the weight of the smelting furnace 17, reducing the stress on individual support points, and ensuring the stability of the smelting furnace 17 in various operating states.
[0032] More specifically, the front drive assembly includes a first motor 3, which is fixedly mounted on the upright plate 2. The first motor 3 is connected to the first collar 13 for transmission, and the first motor 3 drives the first collar 13 to rise or fall.
[0033] Among them, the first motor 3, as the core power source of the front drive component, achieves precise control of the first shaft 15 through the transmission connection with the first collar 13.
[0034] More specifically, the front drive assembly also includes a first worm 5, a first rotating shaft, a first rack 11, a first worm wheel 7, and a first gear 9. The first rotating shaft passes through the vertical plate 2 and is rotatably connected to it. The first worm wheel 7 is fixedly installed at one end of the first rotating shaft, and the first gear 9 is fixedly installed at the other end of the first worm wheel 7. The first worm 5 is rotatably installed on one side wall of the vertical plate 2, and the first worm 5 meshes with the first worm wheel 7. The output shaft end of the first motor 3 is drively connected to one end of the first worm 5. The first rack 11 is longitudinally slidably installed on one side wall of the vertical plate 2 near the melting furnace 17, and the first rack 11 meshes with the first gear 9. The lower end of the first rack 11 is fixedly connected to the first collar 13.
[0035] When the first motor 3 starts, its output shaft drives the first worm 5 to rotate. The first worm 5 meshes with the first worm wheel 7, causing the first worm wheel 7 to rotate, which in turn drives the first gear 9 to rotate. The first gear 9 meshes with the first rack 11, and the first rack 11 moves upward under the drive of the first gear 9, thereby driving the first collar 13 to rise along the first shaft 15. This transmission method not only achieves precise displacement control but also has high transmission efficiency and reliability. This structural design allows the power of the first motor 3 to be precisely transmitted to the first collar 13 through the worm gear and rack transmission, realizing the upward or downward control of the first shaft 15. The worm gear transmission has a self-locking function, which can keep the position of the first collar 13 unchanged when the first motor 3 stops working, ensuring the stability of the smelting furnace 17.
[0036] More specifically, the rear drive assembly includes a second motor 4, which is fixedly mounted on the upright plate 2. The second motor 4 is connected to the second collar 14 for transmission, and the second motor 4 drives the second collar 14 to rise or fall.
[0037] Among them, the second motor 4 serves as the power source for the rear drive assembly and achieves control of the second shaft 16 through a transmission connection with the second collar 14.
[0038] More specifically, the rear drive assembly also includes a second worm gear 6, a second rotating shaft, a second worm wheel 8, a second gear 10, and a second rack 12. The second rotating shaft passes through the wall of the vertical plate 2 and is rotatably connected to it. The second worm wheel 8 is fixedly installed at one end of the second rotating shaft, and the second gear 10 is fixedly installed at the other end of the second rotating shaft. The second worm gear 6 is rotatably installed on one side wall of the vertical plate 2. The output shaft end of the second motor 4 is connected to one end of the second worm gear 6 for transmission, and the second worm wheel 8 meshes with the second worm gear 6. The second rack 12 is slidably installed on the side wall of the vertical plate 2 near the melting furnace 17. The second rack 12 meshes with the second gear 10, and the lower end of the second rack 12 is fixedly connected to the second collar 14.
[0039] When the second motor 4 starts, its output shaft drives the second worm 6 to rotate. The second worm 6 meshes with the second worm wheel 8, causing the second worm wheel 8 to rotate, which in turn drives the second gear 10 to rotate. The second gear 10 meshes with the second rack 12, and the second rack 12 moves upward under the drive of the second gear 10, thereby driving the second collar 14 to rise along the second shaft 16. This transmission method is similar to the front drive assembly, enabling precise control of the second shaft 16 and ensuring the stability of the smelting furnace 17 during tilting. This structural design allows the power of the second motor 4 to be precisely transmitted to the second collar 14 through worm gear and rack transmission, achieving control over the rising or falling of the second shaft 16. The self-locking function of the worm gear transmission also ensures that the position of the second collar 14 remains unchanged when the second motor 4 stops working, ensuring the stability of the smelting furnace 17.
[0040] In operation, the lead alloy raw material is first added to the melting furnace 17 through the feed inlet 19, and then the melting furnace 17 is started for heating and melting. During the melting process, the melting furnace 17 remains vertical, and the lead alloy raw material melts inside the furnace. After melting is completed, the first motor 3 and the second motor 4 are started simultaneously. The first motor 3 drives the first collar 13 to move upward along the first shaft 15 through the transmission of the first worm 5, the first worm wheel 7, the first gear 9, and the first rack 11; the second motor 4 drives the second collar 14 to move upward along the second shaft 16 through the transmission of the second worm 6, the second worm wheel 8, the second gear 10, and the second rack 12. When the melting furnace 17 detaches from the base 1, the first motor 3 stops rotating, while the second motor 4 continues to rotate, causing the second rack 12 to pull the second collar 14 and the second shaft 16 upward. At this time, the first shaft 15 remains stationary, and the melting furnace 17 rotates around the first shaft 15 as the center, allowing the molten lead alloy to flow smoothly out from the discharge port 18.
[0041] After the lead alloy liquid is completely poured out, the second motor 4 reverses and drives the second gear 10 to rotate through the second worm gear 8, causing the second rack 12 to move downward. When the smelting furnace 17 returns to the vertical position, the first motor 3 starts to reverse, causing the first rack 11 and the second rack 12 to simultaneously drive the first shaft 15 and the second shaft 16 to move downward, so that the smelting furnace 17 remains vertical and falls onto the base 1, completing one discharge cycle.
[0042] Example 2, please refer to Figures 4 to 5 The main difference between this embodiment and Embodiment 1 is that the front drive assembly includes a first telescopic member 20, which is fixedly mounted on the upright plate 2. The output shaft end of the first telescopic member 20 is fixedly connected to the outer side wall of the first collar 13. The first telescopic member 20 is either a hydraulic cylinder or a servo electric cylinder. The extension and retraction of the output shaft of the first telescopic member 20 can drive the first collar 13 to rise or fall.
[0043] The rear drive assembly includes a second telescopic member 21, which is fixedly mounted on the upright plate 2. The output shaft end of the second telescopic member 21 is fixedly connected to the outer wall of the second collar 14. The second telescopic member 21 is either a hydraulic cylinder or a servo electric cylinder. The extension and retraction of the output shaft of the second telescopic member 21 can drive the second collar 14 to rise or fall.
[0044] This structural change allows for more diverse drive methods, enabling the selection of appropriate telescopic components based on actual production needs. Hydraulic cylinders offer greater thrust and higher stability, making them suitable for heavy-duty operation of the smelting furnace 17; servo electric cylinders, on the other hand, provide higher precision and response speed, enabling more accurate displacement control. During operation, the first telescopic component 20 and the second telescopic component 21 respectively drive the first collar 13 and the second collar 14 to move along the first shaft 15 and the second shaft 16, achieving the rising, tilting, and lowering movements of the smelting furnace 17. Its working principle is similar to that of Embodiment 1, achieving stable material discharge from the smelting furnace 17 through step-by-step movement, while simplifying the drive structure and reducing maintenance costs and repair difficulty.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
