Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to a grinding equipment for cleaning the inner wall of threaded steel pipes. Background Technology

[0002] Spiral welded steel pipe, also known as spiral steel pipe, is a type of steel pipe made by rolling steel strip (or coil) into shape and then welding it with a spiral weld seam. Spiral welded steel pipe has advantages such as stable structure, excellent material quality, and low production cost, playing a vital role in modern infrastructure construction. During the manufacturing process of spiral welded steel pipe, the inner wall of the manufactured pipe needs to be cleaned, generally using grinding equipment.

[0003] When grinding and cleaning the inner wall of threaded steel pipes, the grinding equipment utilizes a grinding structure. However, while the grinding structure can adapt to the inner wall of the threaded steel pipe, it is not adjustable and is only suitable for grinding pipes of the same type. For threaded steel pipes of different diameters, different types of grinding structures are required, resulting in poor adaptability. Furthermore, as grinding continues, the grinding structure wears down, meaning that even for the same type of threaded steel pipe, a worn-down grinding structure cannot effectively clean the inner wall, leading to mediocre grinding results. Utility Model Content

[0004] The main purpose of this utility model is to provide a cleaning and grinding device for the inner wall of threaded steel pipes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-3 As shown, a threaded steel pipe inner wall cleaning and grinding device includes a movable rod 1, a drive shaft 2 inside the movable rod 1, and a rotating frame 3 connected to the end of the drive shaft 2. A support frame 4 is provided on the movable rod 1 and connected to the rotating frame 3. An adjustable grinding structure 5 is installed on the rotating frame 3. A motor 6 is provided at the end of the movable rod 1 and connected to the drive shaft 2. A fixed plate 7 is fixed on the movable rod 1, and a movable rod 8 is fixedly installed on the fixed plate 7. A groove 9 is provided on the rotating frame 3, and the rotating frame 3 is fixedly connected to the support frame 4. The support frame 4 is rotatably connected to the movable rod 1.

[0019] When cleaning the inner wall of a threaded steel pipe using a grinding equipment, the equipment is mounted on a drive frame, which stably supports the pipe in a suitable position. After activating the structure on the drive frame, the moving rod 8 moves along with the movable rod 1 via the fixed plate 7. The movable rod 1 then moves the rotating frame 3, the support frame 4, and the adjustable grinding structure 5. Once the adjustable grinding structure 5 enters the threaded steel pipe, it is adjusted so that its end contacts the inner wall of the pipe. Then, the motor 6 is activated, and it drives the rotating frame 3 via the transmission shaft 2, thereby driving the adjustable grinding structure 5 to rotate and grind the inner wall of the threaded steel pipe. During the grinding process, the moving rod 8, the fixed plate 7, and the movable rod 1 move slowly, achieving complete grinding of the inner wall of the threaded steel pipe. Simultaneously, the support frame 4 rotates on the movable rod 1 without affecting the rotation of the rotating frame 3, while providing support and ensuring stable grinding.

[0020] According to the above implementation scheme, the adjustable grinding structure 5 includes an adjusting seat 501, an adjusting rod 502, a guide rod 503, a bidirectional screw 504, an elastic grinding component 505, and an adjusting wheel 506. The adjusting seat 501 is fixedly connected to the adjusting rod 502, and the adjusting rod 502 is located in the groove 9 on the rotating frame 3. The guide rod 503 is fixed on the adjusting seat 501 and is movably connected to the rotating frame 3. The bidirectional screw 504 is fixedly connected to the adjusting wheel 506, and the bidirectional screw 504 is threadedly connected to the adjusting rod 502. The elastic grinding component 505 is fixed on the adjusting seat 501.

[0021] When adjusting the adjustable grinding structure 5, the bidirectional screw 504 in the groove 9 is rotated by the adjusting wheel 506. Under the action of the bidirectional screw 504, the two adjusting rods 502 move, causing the two adjusting seats 501 to move on the rotating frame 3 via the guide rod 503 until the elastic grinding component 505 contacts the inner wall of the threaded steel pipe. After starting the grinding equipment, the rotating frame 3 rotates with the adjustable grinding structure 5, and the elastic grinding component 505 performs grinding work on the inner wall of the threaded steel pipe.

[0022] The elastic grinding assembly 505 includes a mounting plate 5051, a connecting plate 5052, a support block 5053, an elastic plate 5054, a grinding brush 5055, a spring 5056, and mounting screws 5057. The mounting plate 5051 is fixedly connected to the connecting plate 5052, and the connecting plate 5052 is mounted on the adjusting seat 501 by the mounting screws 5057. The support block 5053 and the elastic plate 5054 are fixedly connected, and the support block 5053 is connected to the mounting plate 5051. The grinding brush 5055 is evenly distributed on the elastic plate 5054. One end of the spring 5056 is fixedly connected to the mounting plate 5051, and the other end is fixedly connected to the elastic plate 5054.

[0023] Before grinding, when adjusting the position of the elastic grinding component 505, the grinding brushes 5055 on the elastic plate 5054 approach the inner wall of the threaded steel pipe. The grinding brushes 5055 at both ends of the elastic plate 5054 first contact the inner wall of the threaded steel pipe and are limited. After the elastic plate 5054 is subjected to force, the two ends deform and compress the spring 5056, while the middle part does not deform due to the support block 5053 on the mounting plate 5051. This allows the grinding brushes 5055 to fully conform to the inner wall of the threaded steel pipe. After adjustment, grinding is performed, and the grinding brushes 5055 clean the inner wall of the threaded steel pipe. If necessary, the mounting screws 5057 on the connecting plate 5052 can be removed to disassemble the entire elastic grinding component 505 for replacement. The structure is simple and the operation is convenient and quick.

[0024] It should be noted that the adjustable grinding structure 5 allows for the adjustment of the position of the adjusting seat 501 and the elastic grinding component 505, making it suitable for threaded steel pipes of different diameters. It offers high flexibility and adaptability. The bidirectional screw 504 drives the adjustment rod 502, enabling synchronous adjustment of both sets of adjustment rods 502 and the adjusting seat 501, ensuring adjustment accuracy. Furthermore, it allows for arbitrary adjustment within the adjustment range, resulting in high adaptability. The elastic grinding component 505, used in conjunction with the spring 5056 and the elastic plate 5054, allows the grinding brush 5055 to adhere to the inner wall of the threaded steel pipe through deformation of the elastic plate 5054, maximizing the grinding area and improving grinding efficiency and effect.

[0025] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
