Description

Technical Field

[0001] This utility model relates to the field of industrial electric furnaces, specifically an industrial electric furnace equipped with a lifting workpiece placement rack. Background Technology

[0002] Industrial electric furnaces are industrial furnaces that utilize the electrothermal effect for heating. They are widely used in industrial production processes such as heating, smelting, and heat treatment. They typically consist of the furnace body, electrical equipment (such as power regulators and furnace transformers), switches, auxiliary electrical appliances (such as current chokes and compensation capacitors), vacuum equipment (if a vacuum environment is required), detection and control instruments (such as electrical instruments and thermal instruments), automatic adjustment systems, and furnace mechanical equipment (such as feeding and discharging machinery and furnace tilting devices). They convert electrical energy into heat energy in different ways to heat materials. For example, resistance furnaces use the Joule heat generated by current passing through a conductor as a heat source, induction furnaces use the induced electrothermal effect of materials to generate eddy currents in the materials through electromagnetic induction, and electric arc furnaces use the electric arc heating effect to melt metals and other materials.

[0003] Industrial electric furnaces are required for heating materials. However, existing industrial electric furnaces using lifting workpiece racks suffer from lubrication problems. This leads to increased friction during lifting, resulting in less smooth operation, reduced efficiency, and potential wear on the rack structure, shortening its lifespan. Furthermore, lubrication difficulties make it hard for operators to precisely control the lifting speed and position of the rack, leading to under-lifting or over-lifting, which affects the heating effect and the normal operation of the industrial electric furnace. In addition, lack of effective lubrication can cause the rack to jam, resulting in material displacement or even falling. This not only wastes materials but may also damage other internal components of the industrial electric furnace, increasing maintenance costs and safety hazards. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem of inconvenient lubrication when using lifting workpiece racks for material lifting in existing industrial electric furnaces, this invention proposes an industrial electric furnace with a lifting workpiece rack. This addresses the issue of lubrication difficulties, which increase friction during lifting, hindering smooth operation, reducing work efficiency, and potentially causing wear and tear on the rack structure, shortening its lifespan. Furthermore, lubrication difficulties make it hard for operators to accurately control the lifting speed and position of the rack, leading to incomplete or excessive lifting, which affects the heating effect of the material and the normal operation of the industrial electric furnace. In addition, lack of effective lubrication can cause the rack to jam, resulting in material displacement or even falling. This not only wastes materials but may also damage other internal components of the industrial electric furnace, increasing maintenance costs and safety hazards.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an industrial electric furnace with a lifting workpiece placement rack, including an industrial electric furnace body, a support leg fixedly connected to the bottom of the industrial electric furnace body, the number of the support leg is four, a support plate fixedly connected to the bottom of the support leg, a support rod fixedly connected to the top of the support plate, the number of the support rod is four, a reinforcing frame fixedly connected to the top of the support rod, one side of the reinforcing frame is fixedly connected to the surface of the industrial electric furnace body, and a lubrication mechanism is provided on both sides of the industrial electric furnace body; The lubrication mechanism includes a mounting plate, which is fixedly connected to the industrial electric furnace body on the side closest to the furnace body. A storage tank is fixedly connected to the top of the mounting plate, and an oil pump is fixedly mounted on the top of the mounting plate. The oil inlet of the oil pump is fixedly connected to one side of the storage tank, and the oil outlet of the oil pump is fixedly connected to an oil outlet pipe. An addition pipe is fixedly connected between one side of the two support rods, and the top of the addition pipe is fixedly connected to the bottom of the oil outlet pipe.

[0006] Preferably, the top of the storage tank is threaded with a protective cover, and the top of the protective cover has a vent hole.

[0007] Preferably, a hydraulic cylinder is fixedly installed on the top of the reinforcement frame, and the telescopic end of the hydraulic cylinder extends through to the bottom of the reinforcement frame and is fixedly connected to a connecting plate.

[0008] Preferably, a reinforcing plate is fixedly connected to one side of the connecting plate, a placement plate is fixedly connected to the top of the reinforcing plate, and the bottom of the placement plate contacts the top of the industrial electric furnace body.

[0009] Preferably, guide blocks are fixedly connected to both sides of the reinforcing plate, and the surface of the guide blocks is slidably connected to the inner wall of the support rod.

[0010] Preferably, the inner wall of the support rod is provided with a guide groove, and the inner cavity of the guide groove is in contact with the surface of the guide block.

[0011] Preferably, the top of the industrial electric furnace body is provided with a waste oil storage tank, which is used in conjunction with an addition pipe.

[0012] The advantages of this utility model are: This invention, by incorporating a lubrication mechanism, effectively lubricates the lifting workpiece placement rack. An oil pump draws lubricating oil from the storage tank, delivers it through an oil outlet pipe to an adder pipe, and then adds the lubricating oil to the support rod, lubricating the guide blocks within the support rod. This significantly reduces friction during the lifting process, resulting in smoother operation, improved work efficiency, reduced wear on the rack structure caused by excessive friction, and extended service life. Operators can also more precisely control the lifting speed and position of the rack, preventing under- or over-lifting and ensuring accurate material placement. The appropriate heating position ensures the heating effect of the material and maintains the normal operation of the industrial electric furnace. At the same time, effective lubrication prevents the placement rack from jamming, prevents the material from shifting or even falling, reduces material waste, and lowers the risk of damage to other internal components of the industrial electric furnace, thereby reducing maintenance costs and safety hazards. In addition, the vent on the protective cover ensures the air pressure balance in the storage tank, allowing the oil pump to draw lubricating oil more stably. The cooperation of the reinforcement rack, hydraulic cylinder, connecting plate, reinforcement plate, and placement plate structure provides stable support and power for the lifting and lowering of the placement rack. The design of the guide block and guide groove further ensures the stability and accuracy of the lifting and lowering of the placement rack. Attached Figure Description

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an industrial electric furnace equipped with a lifting workpiece placement rack. (See also...) Figures 1-4 An industrial electric furnace with a lifting workpiece placement rack includes an industrial electric furnace body 1. The bottom of the industrial electric furnace body 1 is fixedly connected to a support leg 3, and the number of support legs 3 is four. The bottom of the support leg 3 is fixedly connected to a support plate 5, and the top of the support plate 5 is fixedly connected to a support rod 9, and the number of support rods 9 is four. The top of the support rod 9 is fixedly connected to a reinforcing frame 10. One side of the reinforcing frame 10 is fixedly connected to the surface of the industrial electric furnace body 1. Lubrication mechanisms 2 are provided on both sides of the industrial electric furnace body 1. The lubrication mechanism 2 includes a mounting plate 202, which is fixedly connected to the industrial electric furnace body 1 on the side near the mounting plate 202. A storage tank 201 is fixedly connected to the top of the mounting plate 202. An oil pump 203 is fixedly installed on the top of the mounting plate 202. The oil inlet end of the oil pump 203 is fixedly connected to one side of the storage tank 201. An oil outlet end of the oil pump 203 is fixedly connected to an oil outlet pipe 204. An addition pipe 206 is fixedly connected between one side of the two support rods 9. The top of the addition pipe 206 is fixedly connected to the bottom of the oil outlet pipe 204.

[0018] Reference Figure 3 and Figure 4 The top of the storage tank 201 is threaded with a protective cover 205. A vent 14 is provided on the top of the protective cover 205. The vent 14 helps to balance the air pressure inside and outside the storage tank 201, ensuring that the oil pump 203 can smoothly extract the lubricating oil from the storage tank 201. When the oil pump 203 is working, the air pressure inside the storage tank 201 gradually decreases as the lubricating oil is continuously extracted. Without the vent 14, the oil pump 203's extraction operation would be affected, and it might even fail to function properly. The vent 14 allows outside air to enter the storage tank 201, maintaining stable air pressure inside the tank. Reference Figure 2 and Figure 3A hydraulic cylinder 11 is fixedly installed on the top of the reinforcing frame 10. The telescopic end of the hydraulic cylinder 11 extends to the bottom of the reinforcing frame 10 and is fixedly connected to a connecting plate 7. A reinforcing plate 6 is fixedly connected to one side of the connecting plate 7, and a placement plate 8 is fixedly connected to the top of the reinforcing plate 6. The bottom of the placement plate 8 contacts the top of the industrial electric furnace body 1. By setting up the structure of hydraulic cylinder 11, connecting plate 7, reinforcing plate 6, and placement plate 8, the lifting function of the placement plate 8 can be realized. When the telescopic end of the hydraulic cylinder 11 moves, it will drive the connecting plate 7 to move up and down, thereby driving the reinforcing plate 6 and the placement plate 8 to move up and down together. In this way, the height of the placement plate 8 can be adjusted according to actual needs, making it convenient for operators to place workpieces into or from the industrial electric furnace body 1. The hydraulic cylinder 11 is removed from the body 1, and the reinforcement frame 10 enhances the stability of the hydraulic cylinder 11 installation, ensuring that the hydraulic cylinder 11 will not shake or shift during operation, thus guaranteeing the reliability of the entire lifting system. The design of the reinforcement plate 6 further increases the stability of the connection between the placement plate 8 and the connecting plate 7, making the placement plate 8 safer and more reliable when carrying the workpiece. In actual use, the operator can flexibly control the hydraulic cylinder 11 and precisely adjust the height of the placement plate 8 according to the working conditions of the industrial electric furnace body 1 and the size of the workpiece, improving the convenience and efficiency of the industrial electric furnace. At the same time, the bottom of the placement plate 8 contacts the top of the industrial electric furnace body 1, which can reduce heat loss to a certain extent and improve the energy utilization efficiency of the industrial electric furnace. Reference Figure 2 and Figure 3 Guide blocks 13 are fixedly connected to both sides of the reinforcing plate 6. The surface of the guide block 13 is slidably connected to the inner wall of the support rod 9. By setting the cooperative structure of the guide block 13 and the support rod 9, the reinforcing plate 6 can play a good guiding role in the up and down movement of the reinforcing plate 6. When the hydraulic cylinder 11 drives the connecting plate 7, the reinforcing plate 6 and the placement plate 8 to move up and down, the guide block 13 will slide on the inner wall of the support rod 9. This ensures the stability and accuracy of the reinforcing plate 6 during the movement, avoids the reinforcing plate 6 from deviating or shaking. Moreover, this guiding structure can effectively disperse the force on the reinforcing plate 6, making the force on the entire lifting system more uniform and extending the service life of each component. Reference Figure 2 and Figure 3The inner wall of the support rod 9 is provided with a guide groove 12. The inner cavity of the guide groove 12 contacts the surface of the guide block 13. By setting the contact cooperation between the guide groove 12 and the guide block 13, the accuracy of guidance is further enhanced. The guide groove 12 provides a clear path for the sliding of the guide block 13, so that the guide block 13 can only move along the direction of the guide groove 12, effectively preventing the guide block 13 from shifting laterally during the sliding process. This not only ensures the linear movement of the reinforcing plate 6 during the lifting process, but also makes the lifting action of the entire placement rack more stable and smooth. When the hydraulic cylinder 11 drives the connecting plate 7, the reinforcing plate 6 and the placement plate 8 to perform lifting operations, the guide block 13 slides smoothly in the guide groove 12. The contact area between the two is large, which can evenly distribute the pressure. This even distribution of pressure helps to reduce the wear between the guide block 13 and the guide groove 12, and extend their service life. At the same time, due to the constraint effect of the guide groove 12 on the guide block 13, the reinforcing plate 6 will not shake or swing due to external interference during the movement, thus improving the stability of the placement rack. Reference Figure 1 and Figure 2 The top of the industrial electric furnace body 1 is provided with a waste oil storage tank 4, which is used in conjunction with the addition pipe 206. By setting up the waste oil storage tank 4 and the addition pipe 206, the waste oil generated during the operation of the industrial electric furnace can be conveniently collected and treated. After the lubricating oil is added by the addition pipe 206, the waste oil will flow into the waste oil storage tank 4, avoiding the waste oil from flowing randomly and causing environmental pollution and resource waste. The waste oil storage tank 4 has a certain capacity and can temporarily store a certain amount of waste oil, reducing the workload of frequently cleaning the waste oil. At the same time, the design of the waste oil storage tank 4 makes the centralized treatment of waste oil more convenient, and the staff can regularly collect and reuse the waste oil in the storage tank.

[0019] Working principle: When the industrial electric furnace needs lubrication, the operator starts the oil pump 203. The oil pump 203 draws out the lubricating oil from the storage tank 201. The lubricating oil enters the addition pipe 206 through the oil outlet pipe 204, thereby lubricating the relevant components. The vent 14 ensures that the oil pump 203 can draw oil smoothly. When placing the workpiece, the operator controls the extension and retraction of the hydraulic cylinder 11 according to the working condition of the industrial electric furnace body 1 and the size of the workpiece. When the extension and retraction end extends, it drives the connecting plate 7 to move downward. The connecting plate 7 drives the reinforcing plate 6 and the placement plate 8 to move downward together. The guide block 13 slides along the guide groove 12 on the inner wall of the support rod 9 to ensure that the reinforcing plate 6 descends stably and accurately. Once the placement plate 8 reaches the appropriate height, the operator can place the workpiece onto it. Then, the operator controls the extension end of the hydraulic cylinder 11 to retract, raising the placement plate 8 into the industrial electric furnace body 1 for heating and other operations. Waste oil generated during the operation of the industrial electric furnace flows into the waste oil storage tank 4. The staff regularly collects and reuses the waste oil in the waste oil storage tank 4 to avoid environmental pollution and resource waste. Through the coordinated work of various components, the entire equipment achieves automated lubrication, flexible lifting and lowering of the placement plate 8, and effective collection and treatment of waste oil, improving the ease of use, work efficiency, and energy utilization efficiency of the industrial electric furnace, while extending the service life of each component.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
