Tube scraping device

A tube scraping device including:

• a body adapted to rotate about a pivot pin to be arranged parallel to an axis of the tube to be scraped, said body having two jaws adapted to rotate about said pivot pin between:
• an open position enabling the body to be disposed around the tube and removed therefrom;
• a closed position in which the jaws are closer to the tube than in the open position, said jaws including a first part of driving means adapted to drive said jaws in rotation about the tube while the jaws are in the closed position, and said body holding jaw maneuvering means, for moving said jaws from the open position to the closed position, and the reverse, and tube scraping means adapted to come into contact with an external surface of said tube with a view to scraping it, while said jaws are in the closed position, the scraping means being mounted so as to rotate with the body, and therefore with the jaws,
• a second part of the driving means, said second part being adapted for engaging with the first part said driving means, with a view to causing, in an engaged position, said rotation of the jaws,
• and rolling means mounted at an internal surface of the jaws, away from the scraping means, so as to cause said jaws to roll around an external surface of the tube, while said jaws are in the closed position.
