Description

Technical Field

[0001] This utility model relates to the technical field of steel structure processing equipment, specifically a rust removal device for steel structure processing. Background Technology

[0002] Before being put into use, existing steel pipes usually need to undergo rust removal treatment. This is because when steel pipes are stored, transported, or exposed to environmental factors such as air and moisture for a long time, an oxide rust layer is easily formed on the surface. If it is not removed, the rust layer will not only affect the subsequent welding quality and coating adhesion, but may also accelerate the corrosion process of the steel and reduce the overall durability and safety of the structure.

[0003] According to a public notice (Announcement No.: CN217224993U) of a rust removal device for steel structure processing, the above application includes a support base, a first limiting frame and a second limiting frame. The support base has a sliding groove, and a slider is slidably connected inside the sliding groove. A bracket is fixedly connected to the upper end of the slider, and the bracket is in contact with the support base. A mounting plate is fixedly connected to the support base, and a motor is fixedly mounted on the mounting plate.

[0004] However, in the process of using the above-mentioned equipment for rust removal, the steel brushes set at the top and bottom remove rust from the outer wall of the steel pipe. However, the rust removal on the left and right sides and the oblique corners of the steel pipe is not sufficient, which can easily leave dead corners and cause incomplete rust removal, affecting the quality of subsequent painting or welding. In view of this, we propose a rust removal device for steel structure processing. Utility Model Content

[0017] Compared with the prior art, this utility model provides a rust removal device for steel structure processing, which has the following beneficial effects:

[0018] 1. This rust removal equipment for steel structure processing, through its rust removal components, features a spiral cleaning path for the steel brush. Compared to brushing in a single direction, this allows for more comprehensive coverage of the steel pipe surface, significantly improving rust removal efficiency and cleaning completeness. During the rotation of the steel brush, the bristles continuously change their contact direction with the steel pipe surface from multiple angles, improving the uniformity of rust removal quality. Simultaneously with the horizontal movement and rotation of the steel brush, the steel pipe itself also rotates, increasing the relative speed between the steel pipe and the steel brush. This enhances the grinding effect of the steel brush, achieving higher frequency and denser friction cleaning. Fine adjustments can be made by rotating bolts to adapt to steel pipes of different diameters or wall thicknesses, enhancing the overall adaptability and versatility of the rust removal device.

[0028] like Figures 1-7 As shown, this utility model provides a technical solution: a rust removal device for steel structure processing, including a base 1, a drive motor 2 fixedly connected to the side wall of the base 1, a threaded rod 3 fixedly connected to the output end of the drive motor 2, and a rust removal component 4 provided on the top end face of the base 1. The rust removal component 4 includes a movable frame 401, a rotating ring 402, an external toothed ring 403, a sleeve 404, a movable rod 405, a steel brush 406, a spring 407, a gear 408, a rotating rod 409, a belt 410, a rotating seat 411, a cylinder 412, an adjusting bolt 413, a hexagonal prism 414, a rotating column 415, a hinge rod 416, an extension rod 417, and an abutment plate 418.

[0029] In one embodiment of this utility model, the movable frame 401 is threadedly connected to the threaded rod 3. A rotating ring 402 is rotatably connected to the inner wall of the movable frame 401. A steel brush 406 is provided inside the rotating ring 402. An external toothed ring 403 is fixedly connected to the outer wall of the rotating ring 402. A gear 408 is provided on the inner wall of the movable frame 401. The external toothed ring 403 meshes with the gear 408. A shielding ring 5 is fixedly connected to the inner wall of the rotating ring 402. The shielding ring 5 collects the swept-off rust and prevents debris from entering the threaded groove of the threaded rod 3.

[0030] The cross-section of the rotating rod 409 is hexagonal.

[0031] The two ends of the rotating rod 409 are rotatably connected to the base 1. A pulley is fixedly connected to the side wall of the rotating rod 409. The pulley is connected to the belt 410 for transmission. A second pulley is fixedly connected to the side wall of the threaded rod 3. The second pulley is connected to the belt 410 for transmission.

[0032] Rotary seat 411 is rotatably connected to seat body 1. A cylinder 412 is fixedly connected to the side wall of rotary seat 411. An adjusting bolt 413 is threadedly connected to the side wall of rotary seat 411. A hexagonal prism 414 is fixedly connected to the end face of adjusting bolt 413. A through hole is opened on the side wall of cylinder 412. A pulley three is fixedly connected to the outer wall of cylinder 412. The pulley three is connected to belt two 7 for transmission. A pulley four is fixedly connected to the side wall of threaded rod 3. The pulley four is connected to belt two 7 for transmission.

[0033] The rotating column 415 is rotatably connected to the inner wall of the cylinder 412. The side wall of the rotating column 415 is hinged with a hinge rod 416. The end face of the hinge rod 416 is hinged with an extension rod 417. The end face of the extension rod 417 is fixedly connected with an abutment plate 418. The end face of the cylinder 412 is sleeved with a hexagonal prism 414. The extension rod 417 is slidably connected with a through hole. The outer wall of the abutment plate 418 is sleeved with a steel pipe 6. The abutment plate 418 achieves internal clamping of the steel pipe 6.

[0034] A sleeve 404 is fixedly connected to the inner wall of the rotating ring 402. A movable rod 405 is sleeved on the inner wall of the sleeve 404. A steel brush 406 is fixedly connected to the end face of the movable rod 405. A spring 407 is fixedly connected to the bottom surface of the inner side of the sleeve 404. The end of the spring 407 away from the sleeve 404 is fixedly connected to the movable rod 405.

[0035] Under the elastic action of spring 407, steel brush 406 is tightly pressed against the outer wall of steel pipe 6. Drive motor 2 drives threaded rod 3 to rotate, causing moving frame 401 to move laterally, so that steel brush 406 cleans the surface of steel pipe 6. The rotation of threaded rod 3 drives rotating rod 409 to rotate through belt 410. Rotating rod 409 drives gear 408 to rotate, and gear 408 drives rotating ring 402 to rotate. Thus, steel brush 406 rotates while moving laterally, so that the cleaning path of steel brush 406 is spiral. Compared with brushing in one direction, it can more comprehensively cover the surface of steel pipe 6, significantly improving rust removal efficiency and cleaning integrity. During the rotation of steel brush 406, the bristles can continuously change the contact direction with the surface of steel pipe 6 from multiple angles, avoiding local brush marks or uneven cleaning caused by unidirectional movement, and improving the uniformity of rust removal quality.

[0036] The rotation of the threaded rod 3, driven by the belt 7, drives the cylinder 412 and the rotating seat 411 to rotate, which in turn causes the rotating seat 411 to drive the steel pipe 6 to rotate. The rotation speed of the cylinder 412 and the steel pipe 6 is opposite to the rotation speed of the rotating ring 402. While the steel brush 406 moves laterally and rotates, the steel pipe 6 also rotates, which increases the relative speed between the steel pipe 6 and the steel brush 406. This enhances the polishing effect of the steel brush 406, achieves higher frequency and denser friction cleaning, and improves uniformity.

[0037] Rotating the adjusting bolt 413 causes the hexagonal prism 414 to rotate, which in turn drives the rotating column 415 to rotate. This causes the hinge rod 416 to rotate around the rotating column 415, allowing the extension rod 417 and the abutment plate 418 to extend and retract outside the cylinder 412. Consequently, the abutment plate 418 abuts against the inner wall of the steel pipe 6, providing radial support and positioning for the steel pipe 6 from the inside. This prevents the steel pipe 6 from swaying, becoming eccentric, jumping, or slipping during rotation. Fine adjustments can be made by rotating the bolt to accommodate steel pipes 6 of different diameters or wall thicknesses, enhancing the adaptability and versatility of the entire rust removal device. It eliminates the need for frequent changes to the structure or fixtures, thus improving operational efficiency.

[0038] In addition, a rubber strip 8 is fixedly connected to the outer wall of the abutment plate 418. The direction of the rubber strip 8 is parallel to the axis of the steel pipe 6. During the rotation of the steel pipe 6, the rubber strip 8 adheres to the inner wall of the steel pipe 6, and the friction between the rubber and the steel is greater, which can significantly enhance the clamping stability and anti-slip effect, and improve the clamping stability of the inner wall of the steel pipe 6.

[0039] In this invention, during use, the steel brush 406, under the elastic action of the spring 407, tightly abuts against the outer wall of the steel pipe 6. The drive motor 2 drives the threaded rod 3 to rotate, causing the moving frame 401 to move laterally, thus cleaning the surface of the steel pipe 6 with the steel brush 406. The rotation of the threaded rod 3, through the transmission of the belt 410, drives the rotating rod 409 to rotate, which in turn drives the gear 408 to rotate. The gear 408 then drives the rotating ring 402 to rotate, thereby causing the steel brush 406 to clean the surface of the steel pipe 6 while moving laterally. Rotation allows the cleaning path of the steel brush 406 to be spiral, which can more comprehensively cover the surface of the steel pipe 6. The rotation of the threaded rod 3, through the transmission of the belt 7, drives the cylinder 412 and the rotating seat 411 to rotate, so that the rotating seat 411 drives the steel pipe 6 to rotate. The rotation speed of the cylinder 412 and the steel pipe 6 is opposite to the rotation speed of the rotating ring 402. While the steel brush 406 moves laterally and rotates, the steel pipe 6 itself is also rotating, which increases the relative motion speed between the steel pipe 6 and the steel brush 406, which can enhance the polishing effect of the steel brush 406.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
