PURPOSE:To provide a substrate treating device in pipe line coating capable of efficiently peeling off a coating surface on a pipe line without almost manual work and making the substrate surface beautiful. CONSTITUTION:This device is moved on a pipe line along the axial direction by a caster 20, etc. Rotary power of an air motor 2 is transformed to oscillation movement by cams 5a, 5b, and oscillating plates 3a, 3b are oscillated in the directions opposite to each other. A grinding belt whose one end is fixed to the one of the oscillation ends of the oscillating plates 3a, 3b, and another end is fixed to the other end of the oscillating ends via the roller 19 while being circled around a pipe line periphery via a roller 19 moves back and forth on the peripheral surface of the pipe line, thus a coating surface can be peeled off. Since a stretched state of the belt can be adjusted by a roller position adjustment mechanism, and one pair o the oscillating plates is oscillated in the direction opposite to each other, vibration is made small. |
