All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a hand-held drum steel bar rust remover, including a housing 1, the housing 1 is welded and fixed to the outside of the arc-shaped sleeve 2, a connecting wire is arranged on the side of the arc-shaped sleeve 2, a rectangular through groove 3 is opened on the surface of the arc-shaped sleeve 2, the rectangular through groove 3, the arc-shaped rotating cylinder 11 and the arc-shaped plate 20 are all arc-shaped and provided with openings, one end of the rectangular through groove 3 is rotatably connected to one end of the rotating shaft 4, the outside of the rectangular through groove 3 is welded and fixed to the gear 1 5, one end of the rotating shaft 4 is welded and fixed to the transmission wheel 6, the outside of the arc-shaped sleeve 2 is connected and fixed to the motor 7 by bolts, the output end of the motor 7 is welded and fixed to the driving wheel 8, a transmission belt 9 is arranged on the outside of the driving wheel 8, the inner wall of the housing 1 is connected and fixed to the outside of the limiting roller 10, the outside of the limiting roller 10 is slidably connected to the inside of the limiting groove 12, the arc-shaped rotating cylinder 11 is sleeved inside the housing 1, a limiting groove 12 is opened on the outside of the arc-shaped rotating cylinder 11, the outside of the arc-shaped rotating cylinder 11 is welded and fixed to the arc-shaped gear ring 1 13, the inside of the arc-shaped rotating cylinder 11 is welded and fixed to the fixing plate 14, the fixing plate 14 is rotatably connected to one end of the rotating shaft 2 15, the outside of the rotating shaft 2 15 is threadedly connected to the moving block 16, the moving block 16 is hinged to one end of the hinged plate 17, one end of the hinged plate 17 is hinged to the grinding plate 18, one end of the rotating shaft 2 15 is welded and fixed to the gear 2 19, the outside of the arc-shaped rotating cylinder 11 is rotatably connected to the arc-shaped plate 20, the inside of the arc-shaped plate 20 is welded and fixed to the gear ring 2 21, the outside of the housing 1 is welded and fixed to the handle 22,
[0021] To ensure the stable rotation of the arc-shaped rotating cylinder 11 and the grinding plate 18, one end of the rotating shaft 4 extends to the outside of the housing 1 and is welded and fixed to the transmission wheel 6. The number of the rotating shafts 4 is two and they are symmetrically distributed. The transmission wheel 6 is connected to the motor 7 through the transmission belt 9. The number of the transmission wheels 6 is two and they are respectively located at the topmost and lowermost ends of the arc-shaped sleeve 2. In this way, it is ensured that no matter what angle the arc-shaped rotating cylinder 11 rotates to, there is at least one gear 1 5 that drives the arc-shaped rotating cylinder 11 to rotate through the arc-shaped gear ring 1 13, avoiding the situation that the driving force disappears during the rotation of the arc-shaped rotating cylinder 11.
[0022] The gears 1 5 are symmetrically distributed on the outside of the rotating shaft 4, and the outside of the gears 1 5 is meshed with the arc-shaped gear ring 1 13. The motor 7 drives the driving wheel 8 to drive the transmission belt 9 to make the transmission wheel 6 and the rotating shaft 4 rotate synchronously. The rotation of the arc-shaped rotating cylinder 11 is achieved through the meshing of the gear 1 5 and the arc-shaped gear ring 1 13.
[0023] To limit the rotation of the arc-shaped rotating cylinder 11 and prevent the arc-shaped rotating cylinder 11 from shaking during rotation, the outer side of the limiting roller 10 is slidably connected to the inner wall of the limiting groove 12. The limiting rollers 10 are evenly distributed in a circumferential array around the circle of the arc-shaped rotating cylinder 11. The rotation of the arc-shaped rotating cylinder 11 is limited by the sliding of several limiting rollers 10 inside the limiting groove 12.
[0024] To ensure that the grinding plate 18 fits the surface of the drum steel bar, opposite threads are provided on both sides of the fixing plate 14. The number of the second rotating shafts 15 is two and they are symmetrically distributed. Threaded holes are provided on the side surfaces of the second rotating shafts 15, and the second rotating shafts 15 are threadedly connected to the outer sides of the fixing plate 14 through the threaded holes. One end of the second rotating shaft 15 extends to the outside of the fixing plate 14 and is welded and fixed to the second gear 19. Rotating the arc-shaped plate 20 causes the second gear ring 21 to drive the second gears 19 and the second rotating shafts 15 on the upper and lower sides to rotate, so that the moving blocks 16 on both sides move synchronously towards each other. The grinding plate 18 is pushed to move through the hinge plate 17 until the grinding plates 18 on the upper and lower sides fit the outer side of the drum steel bar. At the same time, the outer sides of drum steel bars with different radii can be fitted, thereby improving the rust removal efficiency of the steel bars.
[0025] To prevent relative sliding of the arc-shaped plate 20 during the rotation of the arc-shaped rotating cylinder 11, a damping gasket is provided at the connection between the arc-shaped plate 20 and the arc-shaped rotating cylinder 11. In this way, only by manually rotating the arc-shaped plate 20 can the second gear ring 21 drive the second rotating shaft 15 and the second gear 19 to rotate.
[0026] To ensure the synchronous movement of the grinding plates 18 on the upper and lower sides, the number of the second gears 19 is two. The second gears 19 are meshed with the second gear ring 21. The surface of the grinding plate 18 can be bonded with grinding sheets.
[0027] Working principle: When in use, the staff moves the roller steel bar into the inside of the arc-shaped rotating cylinder 11 through the openings of the arc-shaped sleeve 2 and the arc-shaped rotating cylinder 11, and then rotates the arc-shaped plate 20 to make the second gear ring 21 drive the second gears 19 and the second rotating shafts 15 on the upper and lower sides to rotate, so that the moving blocks 16 on both sides move synchronously towards each other. The grinding plate 18 is pushed to move through the hinge plate 17 until the grinding plates 18 on the upper and lower sides fit the outer side of the drum steel bar. Subsequently, the motor 7 makes the driving wheel 8 drive the transmission belt 9 to make the transmission wheel 6 and the first rotating shaft 4 rotate synchronously. The arc-shaped rotating cylinder 11 rotates through the meshing of the first gear 5 and the first arc-shaped gear ring 13. The rust removal effect on the outer side of the drum steel bar is enhanced by the rotation of the arc-shaped rotating cylinder 11 and the grinding plate 18, making the rust removal on the outer side of the drum steel bar more uniform and effectively reducing the difficulty of rust removal for the staff.
