[0002] Induction melting furnaces are commonly used for melting metals. They utilize a medium-frequency power supply to create a medium-frequency magnetic field, which induces eddy currents within ferromagnetic materials, generating heat and achieving the purpose of heating the material. Generally, the materials to be melted are solid metals. Currently, induction melting furnaces are widely used in industrial production across various fields. However, some existing induction melting furnaces have drawbacks, such as the inconvenience of needing to remove the furnace lining and crucible, and the risk of burns when handling the crucible and metal materials. Utility Model Content

[0003] The purpose of this utility model is to solve at least one problem of the prior art and to propose a lifting control device that facilitates the loading and unloading of materials in an induction melting furnace.

[0004] To achieve the above objectives, this utility model proposes a lifting control device for facilitating the loading and unloading of materials in an induction melting furnace. The device includes a support, a lifting platform, and a lifting control mechanism. The support has a guide rail along its height direction. The lifting platform is mounted on the guide rail and can move up and down along it. The lifting platform is used to fix the induction melting furnace in place. The furnace has a furnace chamber for heating the crucible and an opening communicating with the furnace chamber at its interior and bottom. The lifting control mechanism includes a lifting drive component, a mounting base, a sprocket, and a chain. The lifting drive component is connected to the mounting base and drives the mounting base to move up and down. The sprocket is mounted on the mounting base, and the chain is tensioned and mounted on the sprocket. The first end of the chain is fixed to the support, and the second end of the chain is fixed to the lifting platform.

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a support frame 1, a lifting platform 2, and a lifting control mechanism 3. The support frame 1 is provided with a guide rail 11 along the height direction. The lifting platform 2 is installed on the guide rail 11 and can move up and down along the guide rail 11. The lifting platform 2 is used to fix and install an induction melting furnace 4. The induction melting furnace 4 has a furnace chamber for heating a crucible 5 and an opening connected to the furnace chamber at its interior and bottom, respectively. The lifting control mechanism 3 includes a lifting drive component 31, a mounting base 32, a sprocket 33, and a chain 34. The lifting drive component 31 is connected to the mounting base 32 and drives the mounting base 32 to move up and down. The sprocket 33 is rotatably installed on the mounting base 32 through a rotating shaft. The chain 34 is tensioned and installed on the sprocket 33. The first end of the chain 34 is fixed on the support frame 1, and the second end of the chain 34 is fixed on the lifting platform 2.

[0026] In use, when it is necessary to lift the induction melting furnace 4 to remove material from the crucible 5, the lifting drive 31 drives the mounting base 32 to move upward. After the mounting base 32 moves upward, the sprocket 33 rotates, and the chain 34 pulls the lifting platform 2 upward along the guide rail 11, thereby causing the induction melting furnace 4 to move upward synchronously. The crucible 5 gradually emerges from the furnace chamber of the induction melting furnace 4. After moving to a certain height, the lifting drive 31 stops working, and the crucible 5 is completely separated from the induction melting furnace 4. Conversely, when the crucible 5 has finished feeding and needs to be heated and melted, the lifting drive 31 drives the mounting base 32 to move downward. After the mounting base 32 moves downward, the sprocket 33 rotates, and the chain 34 lowers the lifting platform 2 so that it moves downward along the guide rail 11, causing the induction melting furnace 4 to move downward synchronously. The crucible 5 gradually enters the furnace chamber of the induction melting furnace 4 through the opening at the bottom of the induction melting furnace 4 until it is completely inside the furnace chamber, at which point the lifting drive 31 stops working.

[0027] In this embodiment, the lifting drive component 31 is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0028] In this embodiment, the number of guide rails 11 can be one or more, optionally two, three, or four, with multiple guide rails 11 evenly and parallelly arranged on the support 1. The arrangement of multiple guide rails 11 improves the lifting stability of the lifting platform 2.

[0029] In this embodiment, the lifting platform 2 is provided with a bushing, which is fitted onto the outside of the guide rail 11 to further ensure that the lifting platform 2 is not prone to deviation during the lifting process.

[0030] In this embodiment, refer to Figure 2 A reinforcing support rod is provided on the side of the support 1 away from the induction melting furnace 4, forming a triangular support structure between the reinforcing support rod and the support 1. A counterweight can also be placed on the support 1 to improve the overall stability of the support.

[0031] In this embodiment, the support 1 is equipped with a controller, which is connected to the lifting drive 31 and controls the operation of the lifting drive. This allows the user to control the lifting position of the lifting platform 2 and the height at which the crucible 5 is inserted into the furnace. This enables induction heating of materials at different positions of the crucible 5, and better temperature differentiation and positional heating and melting of metal materials with different melting points.

[0032] In this embodiment, the bracket 1 is provided with multiple wire harnesses, and the wire harnesses are provided with through installation channels. The installation channels are used to install the wires, which makes the wires relatively neat after installation and also provides a certain degree of protection for the wires, avoiding the influence of the high temperature of the induction melting furnace.

[0033] In this embodiment, the bottom of the bracket 1 is provided with a support column for supporting the lifting platform 2, so that the lifting platform just touches the support column when it is lowered to the lowest position.

[0034] In this embodiment, refer to Figure 4 and Figure 5 The crucible 5 is placed on the trolley 6. The bottom of the support 1 is equipped with a guide rail, and the trolley 6 moves linearly along the guide rail, which further facilitates the pushing, pulling and placing of the crucible 5. In order to improve the sealing of the bottom opening of the induction melting furnace, a sealing cover adapted to the opening can also be set on the trolley. The crucible is placed on the sealing cover, and the sealing cover seals the bottom opening of the induction melting furnace.

[0035] In this embodiment, refer to Figure 3 The lifting platform 2 and the induction melting furnace 4 are connected by bolts and nuts, which facilitates disassembly and assembly.

[0036] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
