Technical Field

[0001] The utility model relates to the technical field of steel pipe inner walls, in particular to a steel pipe inner wall cleaning device. Background Art

[0002] Steel pipe is a hollow steel product whose length is much greater than its diameter or circumference. It is categorized by cross-sectional shape into round, square, rectangular, and special-shaped steel pipes; by material, into carbon structural steel pipe, low-alloy structural steel pipe, alloy steel pipe, and composite steel pipe; by application, into pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and by production process, into seamless and welded steel pipes. In the mechanical field, the inner wall of steel pipes requires cleaning to remove impurities adhering to the inner wall of stainless steel pipes.

[0003] According to Chinese patent publication number CN 212550114 U, a steel pipe inner wall cleaning device is disclosed. This device, belonging to the field of steel technology, includes a spray gun stand and a spray gun. The spray gun stand comprises two side supports, a connecting plate, and two V-shaped clamping plates. The connecting plate has a spray gun hole in the middle, and the two sides of the connecting plate are fixedly connected to the side supports, which are connected to the V-shaped clamping plates. The spray gun comprises a hollow spray gun rod, a brush with through holes at both ends, and a brush fixing device. The rear end of the spray gun rod passes through the spray gun hole and is connected to the high-pressure water pump pipeline. The brush fixing device comprises a mesh-shaped brush, and the spray gun rod has multiple spray holes facing the brush. Compared with existing technologies, the device has a simple structure and a reasonable design.

[0004] However, when the cleaning device cleans the inner wall of the steel pipe, it is necessary to manually rotate the rocker to clean the inner wall of the steel pipe, which is cumbersome to operate, has low work efficiency, is inconvenient to adjust the rotation speed of the cleaning brush, and cannot achieve accurate cleaning of the inner wall of the steel pipe. At the same time, the cleaning device does not have a stable fixing mechanism to clamp and fix the steel pipe, which may cause the steel pipe to shift in position during the cleaning process. For this reason, we propose a steel pipe inner wall cleaning device. Utility Model Content
