At the same time, three to four rotation guide rollers 33, which rotate while rotating around a vertical axis (axis parallel to the axis of the tube) on the inner surface of the tube to be polished, are arranged at equal intervals in the circumferential direction. Fixed. Further, the chassis 6 is provided with three to four advancing / retreating guide rollers 34 rollingly contacting the inner surface of the tube to be polished while rotating around a horizontal axis (axis perpendicular to the axis of the tube). It is fixed at equal intervals.

The inner surface of the pipe polishing device is lifted up through the pipe to hang it in the pipe,
When both rotors 1 and 2 are in the tube, the motor 4 is started and polishing is started.

向（例えば時計回り方向）に、第５ギヤ16はその反対方
向（例えば反時計回り方向）にそれぞれ回転する。The rotation of the motor 4 (for example, clockwise rotation) causes the second rotor 2 to rotate in the same direction as the motor 4 (for example, clockwise rotation) via the coupling 8 and the central shaft 3. Is transmitted as. The first gear 10 of the reversing mechanism 5 is in the same direction as the central shaft 3 (eg, clockwise direction).
The second gear 12 is in the opposite direction (for example, a counterclockwise direction), the third gear 14 and the fourth gear 15 are in the same direction as the central axis 3 (for example, a clockwise direction), and the fifth gear 16 is the opposite direction.

Will be done. When the polishing tools attached to the first and second rotors 1 and 2 are brought into sliding contact with the inner surface of the tubular body, a reaction force is generated by the friction of the polishing tools with respect to rotation, and the reaction force causes the second rotor 2 to rotate. Is applied with a force to rotate in the opposite direction to the rotation direction of the central shaft 3, while a force to rotate in the same direction as the central shaft 3 is applied to the first rotor 1.

And, it acts on the central shaft 3 via the reversing mechanism 5 so as to rotate the central shaft 3 in the same direction as the rotation direction, and cancels the reaction force acting from the second rotor 2. The reaction force acting on both the first and second rotors 1 and 2 is determined by the contact pressure of the polishing tool and the coefficient of friction of the polishing tool against the inner surface of the tube. Contact with the inner surface of the
The reaction forces acting on the second rotors 1 and 2 are opposite in direction and have the same strength. Apparently, the chassis 6 has the first and second reaction forces.
The reaction force of both rotors 1 and 2 stops acting.

The cord is prevented from being twisted, and the durability of the cord can be improved. In the above-mentioned one embodiment, the tube inner surface polishing device is moved up and down in the tube by raising and lowering the tube inner surface polishing device by the lifting machine. It does not prevent that it is configured so that it can move by itself in the axial direction.
