Description

Technical Field

[0001] The utility model relates to the field of special metallurgy, in particular to a cover transportation device for vacuum induction melting furnaces with a capacity of more than 5 tons. Background Art

[0002] A vacuum induction melting furnace (Vacuum Induction Melting Furnace, abbreviated as VIM) is a device for melting metals by electromagnetic induction heating under vacuum conditions. It is widely used in the production of high-quality alloys, especially in the fields of aerospace, medical, automotive and nuclear industries. The vacuum induction melting furnace uses intermediate frequency induction heating technology to generate heat in the conductive material through an alternating electromagnetic field, thereby realizing the melting of metals. The induction coil surrounds the crucible containing the metal to be melted. When an alternating current passes through the coil, an induced eddy current will be generated in the metal, rapidly heating up and melting the metal.

[0003] The vacuum induction melting furnace mainly includes the following components;

[0004] Furnace body: Provides a sealed vacuum environment, usually made of materials with high temperature resistance and vacuum integrity retention.

[0005] Intermediate frequency power supply: Provides the electric power required for induction heating, including a power supply, a transformer and a control circuit.

[0006] Vacuum system: Consists of a vacuum pump, a vacuum gauge and valves, responsible for generating and maintaining a vacuum environment.

[0007] Cooling system: Usually adopts water cooling channels and fans to prevent overheating.

[0008] Electric control system: Monitors and controls temperature, vacuum degree and input power.

[0009] A large number of devices are installed inside the vacuum induction furnace shell, which requires convenient access channels for the installation and maintenance of the devices. Small-tonnage furnaces usually adopt the form of side-opening doors, which can simplify the structure. However, vacuum induction furnaces with a capacity of more than 5 tons are usually considered large-tonnage equipment. For vacuum furnaces with a capacity of more than 5 tons, in order to facilitate installation and maintenance, only the form of moving the furnace top cover can be adopted. Due to the large volume of vacuum induction furnaces with a capacity of more than 5 tons, the cover of the vacuum induction furnace with a capacity of more than 5 tons is heavy. It is difficult to operate manually when moving the cover of the vacuum induction furnace with a capacity of more than 5 tons during maintenance operations, which is very inconvenient. Moreover, the relatively large weight of the cover of the vacuum induction furnace with a capacity of more than 5 tons will also pose a safety hazard. Summary of the Utility Model

[0010] A series of simplified concepts are introduced in the utility model content section. These simplified concepts are simplified from the existing technologies in this field and will be further elaborated in the specific implementation section. The utility model content section of the present utility model does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0011] The technical problem to be solved by the present utility model is to provide a transportation device that is easy to operate and can replace manual operation to install or remove the furnace cover of a vacuum induction melting furnace with a capacity of more than 5 tons.

[0017] Two movable support vehicles 4 can reciprocally move along the first guide rail and the second guide rail in a coplanar state to transport the furnace cover 3 of the vacuum induction melting furnace to the furnace opening of the vacuum induction melting furnace or transport the furnace cover 3 of the vacuum induction melting furnace away from the furnace opening of the vacuum induction melting furnace.

[0018] Preferably, further improve the furnace cover transportation device for a vacuum induction melting furnace with a capacity of more than 5 tons. The lifting part 1.2 includes:

[0019] A support cross beam 1.2.1, which is fixedly connected to the fixed part 1.1 of the movable support mechanism 1 or is an integrally formed structure with the fixed part 1.1 of the movable support mechanism 1, and its height is less than the height of the first guide rail;

[0020] A lifting drive device 1.2.2, which is fixed on the support cross beam 1.2.1 and is used to lift or lower the guide rail cross beam 1.2.3;

[0021] The second guide rail is formed on the guide rail cross beam 1.2.3.

[0022] Preferably, further improve the cover transportation device of the vacuum induction melting furnace with a capacity of more than 5 tons. The lifting drive device 1.2.2 is a cylinder with its bottom fixed on the support crossbeam 1.2.1 and its output end connected to the guide rail crossbeam 1.2.3.

[0023] Preferably, further improve the cover transportation device of the vacuum induction melting furnace with a capacity of more than 5 tons. The movable support vehicle 4 includes:

[0024] A support connecting member, which is formed on the top of the vehicle body and is used to connect and fix the connecting part of the vacuum induction melting furnace cover 3.

[0025] Preferably, further improve the cover transportation device of the vacuum induction melting furnace with a capacity of more than 5 tons. The connecting part is a recess formed on the side wall of the vacuum induction melting furnace cover 3;

[0026] The support connecting member is formed as a convex part suitable for the shape of the recess.

[0027] Preferably, further improve the cover transportation device of the vacuum induction melting furnace with a capacity of more than 5 tons. The connecting part is a convex part formed on the side wall of the vacuum induction melting furnace cover 3;

[0028] The support connecting member is formed as a recess suitable for the shape of the convex part.

[0029] Preferably, further improve the cover transportation device of the vacuum induction melting furnace with a capacity of more than 5 tons. The connecting part is a bottomless cylinder formed on the side wall of the vacuum induction melting furnace cover 3, and the side wall of the cylinder is fixedly connected to the side wall of the vacuum induction melting furnace cover 3;

[0034] The lifting side ascends, causing the supporting connecting member to insert into and abut against the connecting portion of the cover of the vacuum induction melting furnace, thereby lifting the cover of the vacuum induction melting furnace away from the furnace opening of the vacuum induction melting furnace; when the first guide rail and the second guide rail are coplanar and connected, the lifting side stops ascending, and the movable support cart is dragged along the second guide rail and the first guide rail away from the furnace opening of the vacuum induction melting furnace to complete the removal of the cover of the vacuum induction melting furnace.

[0035] When it is necessary to install the cover of the vacuum induction melting furnace back onto the furnace opening of the vacuum induction melting furnace, the movable support cart is driven to move onto the second guide rail of the lifting side, causing the lifting side to rise until the bottom height of the cover of the vacuum induction melting furnace is higher than the top height of the furnace opening of the vacuum induction melting furnace; the movable support cart is moved along the second guide rail to align the cover of the vacuum induction melting furnace with the furnace opening of the vacuum induction melting furnace; then, the lifting side is lowered until the connecting portion between the supporting connecting member and the cover of the vacuum induction melting furnace is separated, for the installation of the cover of the vacuum induction melting furnace.

[0036] The utility model replaces manual operation with a mechanical structure, and can quickly and conveniently install or remove the cover of a vacuum induction melting furnace with a capacity of more than 5 tons, providing a high level of safety guarantee while ensuring work efficiency.
