Abstract
Description
Technical Field
[0001] This application relates to the field of spray gun lifting device technology, and more specifically, to a simple top-blown smelting furnace spray gun lifting device. Background Technology
[0002] As a key piece of equipment in the non-ferrous metal smelting process, the top-blown furnace plays a crucial role, with the lance serving as a vital component. The lance is responsible for blowing oxygen and fuel into the furnace to promote the smelting reaction. In actual production, the height of the lance needs frequent adjustment according to the requirements of the smelting process.
[0003] However, existing methods for raising the spray lance have many drawbacks. Some small smelting enterprises still use manual operation to raise the spray lance. This method is not only labor-intensive, but also makes it difficult to ensure the stability of the raising process, which can easily cause the spray lance to shake during the raising process, affecting the uniformity of the reaction inside the furnace and thus reducing product quality. In addition, manual operation also poses certain safety risks, as operators may be injured by harsh environments such as high temperatures and dust.
[0004] To address the aforementioned problems, this application provides a simple top-blown smelting furnace lance lifting device. Utility Model Content
[0005] One objective of this application is to provide a simple top-blown smelting furnace lance lifting device, comprising a horizontal plate, a motor fixedly connected to the top of the horizontal plate, a rotating shaft fixedly connected to the output end of the motor, a main gear fixedly connected to the outer side of the rotating shaft, a driven gear rotatably connected above the horizontal plate, a threaded sleeve fixedly connected to the inner wall of the driven gear, a threaded rod inserted into the internal thread of the threaded sleeve, the bottom end of the threaded rod penetrating the horizontal plate and extending below the horizontal plate, a lifting plate fixedly connected to the bottom end of the threaded rod, a limiting plate fixedly connected to the bottom end face of the horizontal plate, and the lifting plate slidably sleeved on the outer side of the limiting plate, a lance body provided on the surface of the lifting plate, and a limiting component for fixing the lance body provided on the lifting plate.

[0008] Further, the main gear and the driven gear are in meshing transmission connection, and the top end surface of the annular slider is fixedly connected to the bottom end surface of the driven gear.
[0009] Further, the longitudinal section of the annular slider is arranged in a "convex" shape structure, and there are four vertical rods in total, and the four vertical rods are arranged in an annular array.
[0010] Further, a sliding hole is formed in the lifting plate, and the lifting plate is slidably sleeved outside the limiting plate through the sliding hole.
[0011] Further, a sliding groove is formed in the horizontal plate, and a sliding plate is slidably inserted into the sliding groove, and the bottom end of the sliding plate is fixedly connected to the right side of the top end surface of the lifting plate.

[0026] Example:
[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This application discloses a simple top-blown smelting furnace lance lifting device, including a horizontal plate 5, which is fixed to the side wall to increase the overall stability of the device. A motor 7 is fixedly connected to the top of the horizontal plate 5, and a rotating shaft 17 is fixedly connected to the output end of the motor 7. A main gear 8 is fixedly connected to the outer side of the rotating shaft 17. A driven gear 11 is rotatably connected above the horizontal plate 5, and a threaded sleeve 12 is fixedly connected to the inner wall of the driven gear 11. A threaded rod 4 is threaded into the inner thread of the threaded sleeve 12. The bottom end of the threaded rod 4 passes through the horizontal plate 5 and extends to the bottom of the horizontal plate 5. A lifting plate 3 is fixedly connected to the bottom end of the threaded rod 4. The motor 7 is controlled to drive the rotating shaft 17 and the main gear 8 to rotate, and the rotation of the main gear 8 drives the driven gear. The gear 11 rotates, which drives the threaded sleeve 12 to rotate. Due to the function of the limiting plate 6 and the sliding hole 31, and the function of the sliding plate 9 and the sliding groove 51, the lifting plate 3 is limited. The bottom end of the threaded rod 4 is fixedly connected to the lifting plate 3. Therefore, when the threaded sleeve 12 rotates, the screw 10 can drive the lifting plate 3 to move, thereby realizing the lifting of the spray gun body 1. This achieves the lifting of the spray gun body 1 without manual operation, reducing the labor intensity and improving safety. The bottom end face of the horizontal plate 5 is fixedly connected to the limiting plate 6, and the lifting plate 3 is slidably sleeved on the outside of the limiting plate 6. The surface of the lifting plate 3 is provided with the spray gun body 1, and the lifting plate 3 is provided with a limiting component for fixing the spray gun body 1.
[0028] Please see Figure 3 and Figure 4 The limiting assembly includes a rectangular hole 18 on the lifting plate 3. A lead screw 10 is rotatably connected inside the rectangular hole 18, and a rotating handle is fixedly connected to the end of the lead screw 10. Limiting holes are symmetrically formed on the inner wall of the rectangular hole 18, and a fixing frame 2 is slidably inserted into the limiting hole. A connecting plate 19 is connected to the outer threaded sleeve 12 of the lead screw 10. Both ends of the fixing frame 2 are fixedly connected to the connecting plate 19. The spray gun body 1 is inserted into the two fixing frames 2, and then the rotating handle at the end of the lead screw 10 is turned. The rotating handle drives the lead screw 10 to rotate, causing the two fixing frames 2 to move into the rectangular hole 18, thereby using the two fixing frames 2 to cooperate in lifting. The function of plate 3 is to fix the spray gun body 1 on the surface of lifting plate 3 to ensure the stability of the spray gun body 1 during lifting. The top of the horizontal plate 5 is fixedly connected to the upright 16, and the top of the upright 16 is fixedly connected to the fixing ring 14. The top of the fixing ring 14 is provided with an annular groove 15. The annular groove 15 is rotatably connected to a matching annular slider 13. The driven gear 11 is rotatably connected to the top of the fixing ring 14 through the cooperation of the annular slider 13 and the annular groove 15, thereby realizing the rotation limit of the driven gear 11. The main gear 8 and the driven gear 11 are meshed and connected. The top surface of the annular slider 13 is fixedly connected to the bottom surface of the driven gear 11.
[0029] Please see Figure 3 and Figure 4, The longitudinal section of the annular slider 13 is arranged in a "convex" shape structure. There are four vertical rods 16 in total, and the four vertical rods 16 are arranged in an annular array. The four vertical rods 16 play a role in supporting the fixed ring 14. A sliding hole 31 is opened on the lifting plate 3, and the lifting plate 3 is slidably sleeved outside the limiting plate 6 through the sliding hole 31. A sliding groove 51 is opened on the horizontal plate 5, and a sliding plate 9 is slidably inserted inside the sliding groove 51. The bottom end of the sliding plate 9 is fixedly connected to the right side of the top surface of the lifting plate 3. When the lifting plate 3 rises and falls, one end of the lifting plate 3 slides outside the limiting plate 6 through the sliding hole 31, and the other end of the lifting plate 3 moves inside the sliding groove 51 through the sliding plate 9. In this way, the sliding hole 31 and the sliding plate 9 with different-shaped structures at both ends of the lifting plate 3 are used to cooperate with the limiting plate 6 and the sliding groove 51 with different-shaped structures to limit both ends of the lifting plate 3, thereby improving the stability of the lifting of the lifting plate 3 and the spray gun body 1 and avoiding the shaking of the spray gun body 1;
[0030] At the same time, the upper end of the spray gun body 1 abuts against the surface of the sliding plate 9, thereby increasing the contact area between the spray gun body 1 and the device and further enhancing the stability of the spray gun body 1.
[0031] The implementation principle of the embodiment of this application is as follows: Insert the spray gun body 1 into the inside of the two fixing frames 2, and then rotate the rotating handle at the end of the screw rod 10. The rotating handle drives the screw rod 10 to rotate, so that the two fixing frames 2 move into the inside of the rectangular hole 18, thereby using the cooperation of the two fixing frames 2 and the lifting plate 3 to fix the spray gun body 1 on the surface of the lifting plate 3, ensuring the stability of the spray gun body 1 during lifting. At the same time, the upper end of the spray gun body 1 abuts against the surface of the sliding plate 9, thereby increasing the contact area between the spray gun body 1 and the device and enhancing the stability of the spray gun body 1;
[0032] Control the motor 7 to work to drive the rotating shaft 17 and the main gear 8 to rotate. The main gear 8 rotates to drive the driven gear 11 to rotate. The driven gear 11 rotates to drive the threaded sleeve 12 to rotate. Due to the limiting effect of the limiting plate 6 and the sliding hole 31 and the limiting effect of the sliding plate 9 and the sliding groove 51 on the lifting plate 3, and the bottom end of the threaded rod 4 is fixedly connected to the lifting plate 3, so when the threaded sleeve 12 rotates, the screw rod 10 can drive the lifting plate 3 to move, thereby realizing the lifting of the spray gun body 1, realizing the lifting of the spray gun body 1, without manual operation, reducing the labor intensity of workers and enhancing the safety;
[0033] When the lifting plate 3 is raised or lowered, one end of the lifting plate 3 slides on the outside of the limiting plate 6 through the sliding hole 31, while the other end of the lifting plate 3 moves inside the sliding groove 51 through the sliding plate 9. In this way, the sliding hole 31 and the sliding plate 9, which are irregularly shaped structures at both ends of the lifting plate 3, together with the limiting plate 6 and the sliding groove 51, which are irregularly shaped structures, limit the two ends of the lifting plate 3, thereby improving the stability of the lifting plate 3 and the spray gun body 1 when they are raised or lowered, and preventing the spray gun body 1 from shaking.
