Description

Technical Field

[0001] The utility model relates to the field of steel pipe processing, and more specifically, to a device for quickly cleaning the oxide layer on the surface of a steel pipe. Background Art

[0002] Steel is a kind of material with a hollow cross-section, and its length is much greater than the diameter or circumference. According to the cross-sectional shape, it can be divided into round, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the use, it can be divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industries, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, it can be divided into seamless steel pipes and welded steel pipes. Among them, seamless steel pipes are further divided into hot-rolled and cold-rolled types, and welded steel pipes are further divided into straight-seam welded steel pipes and spiral-seam welded steel pipes. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel material. Using steel pipes to manufacture building structure grids, columns and mechanical supports can reduce the weight, save 20-40% of metal, and can also realize factory mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel, simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs.

[0003] For example, a steel pipe surface cleaning device disclosed in the patent publication No. CN220277774U includes a frame body and two threaded rods connected to the surface of the frame body. One end of each threaded rod penetrates the surface of the frame body and extends into the interior of the frame body, and is connected to a connecting plate arranged inside the frame body. On the mutually approaching surfaces of the two connecting plates, mounting plates are fixed. On the upper surface and the bottom surface of the mounting plate, a motor and two connecting members symmetrically distributed along the cross-section of the mounting plate are respectively installed. Connecting rods are provided on the connecting members. The cleaning method that combines a steel brush cleaning device and a blowing cleaning device can achieve thorough cleaning of the dust and residues on the surface of the steel pipe, ensuring that the cleanliness of the steel pipe surface meets the standard.

[0004] As can be seen from the above disclosed solution, at present, when limiting the position of a steel pipe, the left and right sides of the steel pipe are fixed separately by a limiting device. The limiting device is not easy to adjust according to the length of the steel pipe, so it is not easy to fix the left and right positions of steel pipes with different lengths, which affects the effect of limiting the steel pipe and also affects the grinding work. At the same time, during grinding, the outer surface of the steel pipe is frictionally ground by the rotation of a grinding wheel, but the contact area between the grinding wheel and the steel pipe is small, so the grinding area is small, thus reducing the grinding efficiency.
