Description

Technical Field

[0001] The utility model relates to the technical field of furnace top suspension equipment, in particular to a furnace top suspension device convenient to use. Background Technique

[0002] The furnace top suspension device is a device or system used to support and suspend the furnace top structure. It is usually installed at the top of the furnace body to bear the weight of the furnace top and ensure the stability and safety of the furnace top. The design and structure of the furnace top suspension device will vary according to the type, scale and specific requirements of the furnace, but its main functions are similar, that is, to provide reliable support and suspension to maintain the integrity and stability of the furnace top structure. This device is widely used in various furnace types in industries such as metallurgy, chemical engineering, and energy. For example, the Chinese patent discloses "an anti-wear device for furnace top suspension" (Patent No.: CN

[0003] 213090472U). When the driving motor is started, the output end of the driving motor can drive the threaded rod to rotate. Since reverse threads are provided on the threaded rod and the sliders are symmetrically arranged on both sides of the threaded rod in the direction of the threads, the sliders are driven to move towards or away from each other on the threaded rod, driving the furnace top to descend. However, the sliders and the furnace top are only connected by connecting rods, and the furnace top will cause the furnace top to shake left and right when moving downward during the lifting process, making it difficult to fully contact the top of the industrial furnace and reducing the production efficiency of the industrial furnace.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The embodiments of the present utility model will be described below according to its overall structure.

[0020] Refer to Figures 1 to 4, in the embodiment of the present utility model, a convenient-to-use furnace top hanging device includes: a base 1, a guide post 2, and a top plate 3. A support plate 4 is fixedly connected below the top plate 3. A servo motor 5 is installed on one side of the support plate 4, and a bidirectional lead screw 6 is provided on the other side of the support plate 4. A guide groove 7 is opened at the other end below the top plate 3. A fixed block 8 is fixedly connected to the middle section of the bidirectional lead screw 6 below the top plate 3. A damping rod 9 is installed below the fixed block 8. A fixing plate 10 is fixedly connected below the damping rod 9. One side of the fixing plate 10 is hinged with a connecting rod 11. One end of the bidirectional lead screw 6 is screwed with a slider 12. A guide block 13 is fixedly connected above the slider 12. A threaded groove 14 is opened on one side of the slider 12. The other end of the connecting rod 11 is hinged to one side of the slider 12. A furnace top 15 is fixedly connected below the fixing plate 10. The numbers of the support plate 4, the slider 12, the guide block 13, and the threaded groove 14 are all set to two groups. The bidirectional lead screw 6 is arranged between the two groups of support plates 4. The servo motor 5 is connected to the bidirectional lead screw 6. The threaded groove 14 is adapted to the bidirectional lead screw 6. The guide block 13 is adapted to and slidably connected to the guide groove 7. The number of the connecting rods 11 is set to four groups. When it is necessary to lift or lower the furnace top 15, the servo motor 5 is started. The servo motor 5 drives the bidirectional lead screw 6 to rotate. Since the thread directions at both ends of the bidirectional lead screw 6 are opposite, when the lead screw rotates, the two groups of sliders 12 will move towards the midpoint or both ends of the lead screw at the same time. The movement of the slider 12 drives the connecting rod 11 connected thereto to move. Since the other end of the connecting rod 11 is hinged to the fixing plate 10, and the fixing plate 10 is connected to the fixed block 8 through the damping rod 9 below, the movement of the connecting rod 11 will be converted into the lifting and lowering movement of the furnace top 15.

[0021] Refer to Figure 1 and Figure 3 , a support rod 16 is fixedly connected to one side of the furnace top 15. A lifting plate 17 is fixedly connected to one side of the support rod 16. A sliding sleeve 18 is fixedly connected to one side of the lifting plate 17. A through hole 19 is opened above the sliding sleeve 18. A guide post 2 is fixedly connected above the base 1. The numbers of the support rod 16, the sliding sleeve 18, the through hole 19, and the guide post 2 are all set to four groups, and the guide posts 2 are symmetrically arranged at the four ends between the base 1 and the top plate 3. The through hole 19 is adapted to and slidably connected to the guide post 2. The furnace top 15 is connected to the guide post 2 through the support rod 16, the lifting plate 17, and the sliding sleeve 18, so that the furnace top 15 can maintain stability during the lifting and lowering process and ensure the accuracy of the lifting and lowering trajectory.

[0022] Refer to Figure 2 A furnace body 20 is fixedly connected above the base 1. A sealing gasket 21 is provided above the furnace body 20. The sealing gasket 21 is adapted to the size of the furnace top 15. The sealing gasket 21 above the furnace body 20 keeps a certain distance from the furnace top 15 and waits for the furnace top 15 to descend to form a seal.

[0023] The working principle of the present utility model is as follows: The furnace top 15 is connected to the guide column 2 through the support rod 16, the lifting plate 17 and the sliding sleeve 18, so that the furnace top 15 can maintain stability during the lifting process and ensure the accuracy of the lifting trajectory. The servo motor 5 is in a stationary state, and the slider 12 on the bidirectional lead screw 6 is located at the midpoint of its stroke or a preset initial position. The gasket 21 above the furnace body 20 is kept at a certain distance from the furnace top 15, waiting for the furnace top 15 to descend to form a seal. When it is necessary to lift or lower the furnace top 15, the servo motor 5 is started. The servo motor 5 drives the bidirectional lead screw 6 to rotate. Since the thread directions at both ends of the bidirectional lead screw 6 are opposite, when the lead screw rotates, the two groups of sliders 12 will move towards the midpoint or both ends of the lead screw simultaneously. The movement of the slider 12 drives the connecting rod 11 connected thereto to move. Since the other end of the connecting rod 11 is hinged to the fixed plate 10, and the lower part of the fixed plate 10 is connected to the fixed block 8 through the damping rod 9, the movement of the connecting rod 11 will be converted into the lifting movement of the furnace top 15. At the same time, the lifting plate 17 and the sliding sleeve 18 slide along the guide column 2 to ensure the stability of the furnace top 15 during the lifting process. When the furnace top 15 descends to the preset position, the servo motor 5 stops working, the bidirectional lead screw 6 stops rotating, and the slider 12 and the connecting rod 11 maintain their current positions. Therefore, the furnace top 15 is fixed at the current height. After the furnace top 15 descends to the appropriate position, its lower surface is closely attached to the gasket 21 above the furnace body 20 to form an effective seal, ensuring the sealing performance of the furnace body 20 during the heating or processing process. If it is necessary to adjust the height of the furnace top 15 or perform maintenance, the servo motor 5 can be started again, and the lifting adjustment of the furnace top 15 can be achieved by controlling the rotation direction and speed of the motor. After the maintenance is completed, repeat the above steps to lift and fix the furnace top 15 to the appropriate position to ensure the sealing performance of the furnace body.

[0024] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
