Description

Technical Field

[0001] This utility model relates to the field of hole-opening technology for continuous annealing furnace roller installation, and in particular to a novel hole-opening device for refractory material of continuous annealing furnace roller. Background Technology

[0002] The requirements for the refractory pre-reserved holes in the annealing furnace roll area are quite high in terms of refractory masonry quality and hole pre-reservation accuracy. Therefore, how to quickly and accurately pre-reserve the refractory area of ​​the furnace roll becomes the top priority.

[0003] In common practice, refractory pre-drilling holes in the furnace roll area are pre-drilled using composite bricks during the masonry process. However, precise positioning of the composite brick centerline during pre-drilling makes it difficult to install the composite brick grinding roller shaft or the furnace roll itself correctly during later installation. This results in frequent rework and compromises the quality and accuracy of the refractory masonry and pre-drilled holes. Therefore, there is an urgent need to develop a new type of continuous annealing furnace roll refractory pre-drilling device that is structurally simple, easy to operate, and allows for quick and precise drilling of furnace roll holes of different diameters by simply adjusting the height of the adjustable bolt holes on the adjustable flange. This improves drilling speed while ensuring the quality of the refractory material in the furnace roll area, overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0004] The purpose of this invention is to provide a novel refractory pore-opening device for continuous annealing furnace rolls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel refractory drilling device for continuous annealing furnace rollers includes a special drill bit, an extended shaft, a drive motor, a threaded connecting sleeve, a prefabricated beam and slide rail, a handle, an adjustable flange face, a welded sleeve, a prefabricated flange face, a furnace shell roller flange face, and bolt, nut, and gasket assembly.

[0007] The precast beam and slide rail include: a support beam, a slide rail, a slider, a rack, a connecting seat, and support legs. Support legs are fixed to the lower sides of both ends of the support beam to support it. The connecting seat is sleeved on the outside of the support beam. A slider is fixed to the upper, lower, and right sides of the inside of the connecting seat. A slide rail is fixed to the upper, lower, and right sides of the support beam. Each slider is slidably mounted on a slide rail. A rack is fixed to the left side of the support beam.

[0008] The handle is rotatably connected to the connecting seat, and a gear that meshes with the rack is fixed at the bottom of the handle;

[0009] The drive motor is fixedly mounted on the connecting base, and the special drill bit is connected to the drive motor.

[0010] A welded sleeve is welded to the right end of the support beam. The welded sleeve is welded to the adjustable flange face. The adjustable flange face and the prefabricated flange face are detachably fixed by bolts, nuts and gaskets. The prefabricated flange face and the furnace shell roller flange face are detachably fixed by bolts, nuts and gaskets. Multiple adjustable screw holes are provided on both the adjustable flange face and the prefabricated flange face for bolts to pass through.

[0011] Preferably, a threaded connecting sleeve is fixed on the left side of the special drill bit, and the threaded connecting sleeve is fixedly connected to the right end of the extension shaft. A threaded connecting sleeve is fixed on the output shaft of the drive motor, and the threaded connecting sleeve is fixedly connected to the left end of the extension shaft.

[0012] Preferably, the diameter of the special drill bit is 40-350mm and the length is 150-500mm.

[0013] The beneficial effects of this utility model are as follows: In use, the furnace shell roller flange is fixed to the prefabricated flange surface using bolts, nuts, and gaskets. Then, the drive motor is started to rotate the special drill bit. A manual handle is used to rotate the gear, and the meshing force between the gear and rack moves the connecting seat left and right along the support beam. The connecting seat then moves the drive motor, causing the special drill bit to gradually approach the furnace shell roller flange surface for drilling. When drilling for different diameter furnace rollers, loosening the bolts and nuts allows the bolts to move up and down within the adjustable bolt holes. This allows for vertical adjustment of the prefabricated flange surface on the adjustable flange surface, as well as height adjustment of the furnace shell roller flange surface on the prefabricated flange surface. This height adjustment allows for precise drilling of the furnace roller, improving drilling speed while ensuring the quality of the refractory material in the furnace roller area. In summary, this utility model has a simple structure and is easy to operate. For opening holes in furnace rollers of different diameters, only the height of the adjustable screw hole on the adjustable flange surface needs to be adjusted to achieve fast and accurate opening of the furnace roller opening position, which improves the opening speed and ensures the quality of refractory material in the furnace roller area.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] See Figures 1-6In this embodiment of the utility model, a novel refractory drilling device for continuous annealing furnace rollers includes a special drill bit 1, an extended shaft 2, a drive motor 3, a threaded connecting sleeve 4, a prefabricated beam and slide rail 5, a handle 6, an adjustable flange face 7, a welded sleeve 8, a prefabricated flange face 9, a furnace shell roller shaft flange face 10, and a bolt, nut, and gasket assembly 11. The prefabricated beam and slide rail 5 includes a support beam 501, a slide rail 502, a slider 503, a rack 504, a connecting seat 505, and support legs 506. Support legs 506 are fixed to the lower sides of both ends of the support beam 501 to support it. The connecting seat 505 is sleeved on the support beam. On the outside of 501, a slider 503 is fixed to the upper, lower, and right sides of the connecting seat 505. A slide rail 502 is fixed to the upper, lower, and right sides of the support beam 501. Each slider 503 is slidably mounted on a slide rail 502. A rack 504 is fixed to the left side of the support beam 501. The handle 6 is rotatably connected to the connecting seat 505. A gear 601 that meshes with the rack 504 is fixed to the bottom of the handle 6. The drive motor 3 is fixedly mounted on the connecting seat 505. The special drill bit 1 is connected to the drive motor 3. A gear 601 that meshes with the rack 504 is fixed to the left side of the special drill bit 1. A threaded connecting sleeve 4 is fixedly connected to the right end of the extended shaft 2. A threaded connecting sleeve 4 is fixedly mounted on the output shaft of the drive motor 3, and is fixedly connected to the left end of the extended shaft 2. A welded sleeve 8 is welded to the right end of the support beam 501. The welded sleeve 8 is welded to the adjustable flange face 7. The adjustable flange face 7 and the prefabricated flange face 9 are detachably fixed by bolts, nuts, and gasket assembly 11. The prefabricated flange face 9 and the furnace shell roller shaft flange face 10 are detachably fixed by bolts, nuts, and gasket assembly 11. The adjustable flange face 7 and the prefabricated flange face 9 are... Multiple adjustable screw holes 12 are provided on the flange surface 9. The adjustable screw holes 12 are used for bolts to pass through and for height centering adjustment. In use, the operator turns the handle 6 to drive the gear 601 to rotate. The meshing force between the gear 601 and the rack 504 drives the connecting seat 505 to move left and right along the support beam 501. The connecting seat 505 drives the drive motor 3 to move left and right. For opening holes of furnace rollers with different diameters, only the height of the adjustable screw holes 12 on the adjustable flange surface 7 needs to be adjusted to achieve fast and accurate opening of the furnace roller opening position, which improves the opening speed and ensures the quality of refractory material in the furnace roller area.

[0025] The specially designed drill bit 1 has a diameter of 40-350mm and a length of 150-500mm to allow for drilling different types of holes.

[0026] After loosening the bolts and nuts, the bolts can move up and down within the adjustable bolt holes 12. This operation allows for the up and down adjustment of the prefabricated flange face 9 on the adjustable flange face 7, as well as the adjustment of the furnace shell roller flange face 10 on the prefabricated flange face 9. This allows for the adjustment of the drilling positions on the furnace shell roller flange face 10 to meet usage requirements.

[0027] Working principle: In this novel continuous annealing furnace roller refractory drilling device, the furnace shell roller flange 10 is fixed to the prefabricated flange 9 using bolts, nuts, and gaskets 11. Then, the drive motor 3 is started to rotate the special drill bit 1. The handle 6 is manually turned to rotate the gear 601. The meshing force between the gear 601 and the rack 504 causes the connecting seat 505 to move left and right along the support beam 501. The connecting seat 505 then moves the drive motor 3, causing the drive motor 3 to gradually bring the special drill bit 1 closer to the furnace shell roller. Drilling holes in the flange face 10 is sufficient. When drilling holes for furnace rollers with different hole diameters, after loosening the bolts and nuts, the bolts can move up and down within the adjustable bolt holes 12. This operation allows for the up and down adjustment of the prefabricated flange face 9 on the adjustable flange face 7, as well as the height adjustment of the furnace shell roller flange face 10 on the prefabricated flange face 9. This allows for precise height adjustment of the drilling position on the furnace shell roller flange face 10, enabling accurate drilling of the furnace rollers. This improves the drilling speed and ensures the quality of the refractory material in the furnace roller area.
