Description

[0002] The oxide scale cleaning of high-temperature rods can be carried out through a variety of methods, such as polishing: using tools such as grinding wheels, sandpaper or cloth wheels to grind the metal surface, which is suitable for the removal of small or local oxide scales, but the efficiency of removing large-area oxide scales is low; sand blasting: by high-speed jetting abrasives such as sand, steel shots, etc., to impact the metal surface, remove oxide scales and other impurities, suitable for workpieces of various shapes and sizes; high-pressure water jet: using high-pressure water jets to impact the metal surface to remove oxide scales and other attachments, which is environmentally friendly and pollution-free, but requires a higher equipment investment; in addition, there are chemical pickling, alkaline washing, as well as electrolysis, laser method and other methods to remove oxide scales.

[0003] However, no matter which method is used to clean the oxide scale, it must be carried out as a separate cleaning work. The oxide scale is generated very quickly during the production process of high-temperature rods, and as time goes by, the more oxide scale accumulates, the more complicated the cleaning work becomes. Therefore, it is particularly important to clean the oxide scale generated during the transportation of high-temperature rods. This can not only improve work efficiency and reduce the work intensity of staff, but also the amount of oxide scale generated during the production and transportation of high-temperature rods is small, making the cleaning work extremely easy to carry out and the cleaning effect more thorough. Furthermore, there is no need to carry out separate cleaning work for the oxide scale, which simplifies the work process, reduces production costs, and greatly improves production efficiency.

[0017] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] This specific embodiment provides an oxide scale cleaning device during the high-temperature bar conveying process, such as Figure 1-8 As shown, it includes a support 1, which is composed of a plurality of horizontal beams and vertical beams. A rotating shaft 11 arranged along the Z-axis direction is rotatably mounted on the support 1 through a bearing. The rotating shaft 11 is rotatably connected to a turning roller 3, and the rotating shaft 11 is arranged at the tail of the turning roller 3; a splash plate 18 for isolating high temperature and preventing oxide scale from splashing is installed on the turning roller 3; the turning roller 3 includes a bearing plate 301 rotatably connected to the rotating shaft 11, and two bearing plates 301 are provided, and are arranged along the X-axis direction. Symmetrically arranged on the top of the support 1, the bearing plate 301 is rotatably connected with a flip roller 302 through a bearing, and at least three flip rollers 302 are arranged. The side of the bearing plate 301 is rotatably connected with the piston end of the cylinder 303 through a connecting shaft and a shaft seat, and the other end of the cylinder 303 is rotatably connected to the support 1 through a connecting shaft and a shaft seat; the cylinder 303 can make the flip roller 3 flip on the support 1 through the rotating shaft 11, and the maximum angle formed between the flip roller 3 and the support 1 is 45°.

[0019] The intermittent gear assembly 12 is installed on the flip roller 302, and a flip roller 302 is arranged between two adjacent intermittent gear assemblies 12; the intermittent gear assembly 12 includes a driving gear 1201 that is fastened to the end of the flip roller 302, and a first driven gear 1202 and a second driven gear 1203 are symmetrically arranged on both sides of the driving gear 1201, and the first driven gear 1202 and the second driven gear 1203 are fastened to the ends of the adjacent flip rollers 302 respectively; the driving gear 1201 is a non-complete gear structure, that is, one-third of the area of ​​the circumference of the driving gear 1201 is a gear structure, and the other two-thirds of the area is a plane structure, and the first driven gear 1202 and the second driven gear 1203 are both meshed with the one-third portion of the driving gear 1201 where there are gear teeth; In addition, the end of the flip roller 302 on which the driving gear 1201 is arranged is connected to a driving motor 13, and the driving motor 13 is arranged on the outer side of the bearing plate 301. The driving motor 13 drives the flip roller 302 and the driving gear 1201 at the end of the flip roller 302 to rotate in the clockwise direction; when the driving gear 1201 rotates in the clockwise direction, the part with the gear teeth on the driving gear 1201 meshes with the first driven gear 1202, and the first driven gear 1202 rotates in the counterclockwise direction. When the driving gear 1201 meshes with the second driven gear 1203, the second driven gear 1203 rotates in the clockwise direction. At the same time, when the plane portion of the driving gear 1201 contacts the first driven gear 1203 or the second driven gear 1203, the first driven gear 1203 or the second driven gear 1203 does not rotate; therefore, the high-temperature bar material on the turning roller 302 also rolls intermittently in place, which is conducive to more thorough cleaning of the oxide scale.

[0021] A disc steel brush 5 for cleaning oxide scale is arranged above the turning roller 3. Four disc steel brushes 5 are provided. A transmission gear 14 is connected to the disc steel brush 5, and two adjacent transmission gears 14 are meshed with each other. The disc steel brush 5 is rotatably connected to a second drive motor 15 through a bearing. A support plate 6 for receiving the disc steel brush 5 is arranged above the disc steel brush 5. The disc steel brush 5 is rotatably connected to the support plate 6 through a bearing, and the second drive motor 15 is arranged above the support plate 6.

[0022] The support plate 6 is connected to a lifting assembly 7 arranged along the Y-axis direction, and the lifting assembly 7 includes a lifting rod 701 that is fastened to the support plate 6, and two lifting rods 701 are provided and arranged side by side; a row of teeth 702 are arranged on the circumferential surface of the lifting rod 701 along the Y-axis direction, and the row of teeth 702 is meshingly connected with a gear fan 703, and the gear fan 703 is a combination of a fan-shaped structure and a rounded rectangular structure, and gear teeth are distributed on the circumferential surface of the fan-shaped structure of the gear fan 703, and an inner rail 704 is provided on the rounded rectangular structure of the gear fan 703, and the inner rail 704 is a rounded rectangular structure, and a receiving column 705 arranged along the Z-axis direction is rotatably connected on the inner circumferential surface of the inner rail 704, and the receiving column 705 is rotatably connected to the inner circumferential surface of the inner rail 704. A turntable 706 is connected to the bottom; the turntable 706 is rotatably connected to the vertical plate 8 through a bearing, and a support shaft 19 is provided on the vertical plate 8, and the gear fan 703 is rotatably connected to the vertical plate 8 through the support shaft 19; when the turntable 706 rotates in the counterclockwise direction, the receiving column 705 connected to the turntable 706 rotates along a counterclockwise trajectory, thereby driving the gear fan 703 to reciprocate with the support shaft 19 as a fulcrum; when the gear fan 703 rotates in the clockwise direction, the lifting rod 701 moves up in the Y-axis direction; when the gear fan 703 rotates in the counterclockwise direction, the lifting rod 701 moves down in the Y-axis direction, thereby making the support plate 6 connected to the lifting rod 701 move up and down in the Y-axis direction, thereby realizing the lifting and lowering of the disc steel brush 5.

[0023] The turntable 706 is rotatably connected to a third drive motor 16, which is arranged on the side of the vertical plate 8 away from the turntable 706; a connecting plate 9 for fixed support is installed on the side of the vertical plate 8, and the connecting plate 9 is arranged below the turning roller 3 and is fastened to the support 1. An opening 4 for the lifting rod 701 to pass through is provided on the connecting plate 9, and the opening 4 is a circular structure, and two openings 4 are provided.

[0024] The working principle of the present invention is: First, the staff starts the first drive motor 10 and the fourth drive motor 20 to make the power roller 2 symmetrically arranged at the head and tail positions of the turning roller 3 run; then, the staff starts the cylinder 303 to make the angle formed between the turning roller 3 and the support 1 zero. At this time, the turning roller 3 and the power roller 2 are arranged on the same horizontal line; then, the staff starts the drive motor 13 to make the turning roller 302 and the intermittent gear assembly 12 on the turning roller 3 rotate.

[0025] Afterwards, the high-temperature rods are transported on the powered roller 2 located at the head position of the turning roller 3, and then conveyed to the turning roller 3. The heat insulation plate 17 arranged on the powered roller 2 can block the high temperature to prevent the staff from being scalded by the high temperature; then, the staff starts the third drive motor 16, adjusts the height of the lifting rod 701, and moves the lifting rod 701 downward along the Y-axis direction, so that the disc steel brush 5 moves downward along the Y-axis direction and contacts with the high-temperature rods on the turning roller 3. At the same time, the staff turns on the second drive motor 15, so that the disc steel brush 5 rotates under the drive of the transmission gear 14, so as to clean the oxide scale on the high-temperature rod. At the same time, the splash plate 18 arranged on the turning roller 3 can prevent the oxide scale from splashing around during the cleaning process. Moreover, since the high-temperature rod rolls on the turning roller 3 under the action of the intermittent gear assembly 12, the disc steel brush 5 can clean the oxide scale more thoroughly.

[0026] After the oxide scale is cleaned, the staff turns off the second drive motor 15 to stop the disc steel brush 5 from rotating. Then, the staff adjusts the height of the lifting rod 701 through the third drive motor 16 to make the lifting rod move up along the Y-axis direction, thereby making the disc steel brush 5 move up along the Y-axis direction and away from the turning roller 3; then, the staff starts the cylinder 303, and the cylinder 303 drives the turning roller 3 to rotate on the rotating shaft 11, and forms a certain angle between the turning roller 3 and the support 1, so that the high-temperature rod slides on the turning roller 3 to the power roller 2 arranged at the tail of the turning roller 3, and then is transported to the next production link via the power roller 2. At the same time, the splash plate 18 arranged on the turning roller 3 can prevent the high-temperature rod from sliding off the side of the turning roller 3, thereby avoiding the occurrence of safety hazards.
