When removing rust from a steel pipe using this device, first place the steel pipe 32 on the support roller 4, fix one end to the pipe chuck 3, and then drive the steel pipe 27 using the power unit 2 whose rotation speed can be adjusted according to the diameter of the steel pipe. Rotate. Next, a power unit 7, for example, a hydraulic motor, whose speed can be adjusted for the drive unit is operated to reciprocate the cart 5 on the base 1 and pull the guide rod 23 to insert the insertion rod 27 into the steel pipe 32. . Here, a wire brush 15 and an air chisel 16 are provided on the support stand 9 for the rotating steel pipe 32.
As a result, the outer surface of the steel pipe 32 is polished and struck, and the inner surface is also ground with the steel cable 31 of the short pipe 28 attached to the tip of the insertion rod 27, and rust, scale, and concrete lumps attached to the inner and outer surfaces of the steel pipe 32 are removed and polished. .
The optimum rotation speed of the power unit 2 for the pipe chuck 3 can be selected depending on the diameter of the steel pipe 32 to be polished, and the feed rate of the power unit 7 for feeding the drive unit can also be adjusted using a hydraulic motor or the like. By adjusting the power units 2 and 7 according to the diameter of the steel pipe 32 and the degree of rust, the optimum rotational speed of the pipe chuck 3 and feed rate of the cleaning device can be selected. When the insertion rod 27 is inserted into the steel pipe 32, the wire brush 15 and air chisel 16
Since the position of the short pipe 28 does not match, the short pipe 2
Since the pin holes 33a, 33b, and 33c of the insertion rod 27 cannot be fully reached inside the steel pipe 32, for example, if the position of the pin hole 33c near the end of the insertion rod 27 is locked to the holder 26, align the tip of the short tube 28 and the tip of the support stand 9,
The short pipe 28 can further be inserted into the steel pipe 32, and the entire length of the inside of the steel pipe 28 can be cleaned.
