Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, specifically, it relates to a steel pipe inner diameter grinding device. Background Technology

[0002] During manufacturing, welding, or long-term service, steel pipes often have defects on their inner walls, such as oxide layers, weld excess, rust patches, and micro-burrs. These surface irregularities directly lead to reduced fluid transmission efficiency, increased local turbulence, and accelerated pipe wall corrosion and wear; in applications such as precision hydraulic systems and food and pharmaceutical pipelines, they may even cause media contamination or seal failure. However, during the grinding process of the inner diameter of the steel pipe, the debris and cleaning fluid produced by grinding will remain and adhere to the inner wall of the pipe. As grinding continues, the high-speed rotating grinding brush will repeatedly crush the free debris onto the pipe wall. Some particles will embed into the metal matrix under mechanical force, forming scratches or pits, which will damage the smoothness of the inner wall. At the same time, the accumulated debris will hinder the effective contact between the grinding head and the pipe wall, forcing repeated grinding, increasing energy consumption and working time. To address the aforementioned problems, this application proposes a steel pipe inner diameter grinding device. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4 A steel pipe inner diameter grinding device includes a mounting frame 1. A drive motor 2 is fixedly connected to the inner wall of the mounting frame 1.

An adjusting rod 5 is slidably connected to the outer wall of the vertical rod 4. During use, the operator can adjust the position between the adjusting rod 5 and the vertical rod 4 according to the inner diameter of the pipe. A support frame 6 is rotatably connected to the end of the adjusting rod 5 away from the vertical rod 4. A grinding brush 7 is rotatably connected to the inner wall of one end of the support frame 6. A scraper 8 is fixedly connected to the end of the support frame 6 near the grinding brush 7. A collection box 9 is fixedly connected to the outer wall of the support frame 6. An opening is opened on the side of the collection box 9 near the scraper 8. A sliding groove 10 is opened on the inner bottom of the collection box 9. A sliding plate 11 is slidably connected to the collection box 9 through the sliding groove 10. A pull rod 12 is rotatably connected to the top of the sliding plate 11. The connection point between the pull rod 12 and the sliding plate 11 is located on the top side of the sliding plate 11. A closing block 13 is fixedly connected to the end of the pull rod 12 away from the sliding plate 11. In use, the drive motor 2 drives the rotating disk 3 to rotate, which in turn drives the upright rod 4 and the adjusting rod 5 to rotate, and further drives the support frame 6 to rotate. The grinding brush 7 grinds the inner wall of the pipe, and at the same time, the scraper 8 scrapes away the debris stuck on the inner wall of the pipe. Because the outer wall of the scraper 8 is equipped with a baffle, when the scraper 8 scrapes away the debris, the debris is guided by the baffle and enters the interior of the collection box 9 through the holes on the outer wall of the collection box 9. After grinding is completed, the operator can pull the lever 12. Near one end of the closed block 13, since the connection point between the pull rod 12 and the slide plate 11 is located on the top side of the slide plate 11, the slide plate 11 tilts under the pull of the pull rod 12, so that one side of the slide plate 11 abuts against the inner bottom of the collection box 9 and the other side of the slide plate 11 abuts against the inner top of the collection box 9. When the operator pulls the pull rod 12, the slide plate 11 cleans the debris stored inside the collection box 9, so as to facilitate the operator to carry out centralized processing and avoid debris from being stuck inside the pipe.

A tensioner 17 is threadedly connected to the end of the cable 16 away from the rotating disk 3. A tension spring 18 is fixedly connected to the end of the tensioner 17 away from the cable 16.
