Pressurized fluid i.e. gas, supplying tube, scraping device, has rolling units mounted in inner surfaces of jaws and spaced from scraping blade for rolling jaws around outer surface of tube in closed position of jaws

The device has a body (11) carrying a handling unit of jaws separably connected with a remote control unit, to move the jaws between stable open and closed positions. A scraping blade is mounted for rotating with the body and the jaws. A structure (110) carries a jaw driving part (15b) separably eng...

Beschreibung
Zusammenfassung:	The device has a body (11) carrying a handling unit of jaws separably connected with a remote control unit, to move the jaws between stable open and closed positions. A scraping blade is mounted for rotating with the body and the jaws. A structure (110) carries a jaw driving part (15b) separably engaged with another part in engaged position for rotating the jaws. Rolling units (19) are mounted in inner surfaces of the jaws and spaced from the blade to roll the jaws around an outer surface (1a1) of a plastic tube (1) i.e. polyethylene tube, in the closed position. L'invention a pour objet un dispositif de grattage d'un tube (1), comprenant un corps (11) portant des moyens de râpe du tube, et une structure (110) d'entraînement en rotation de ce corps autour du tube. Le corps est pourvu de mâchoires articulées. Une partie (15b) des moyens l'entraînement est portée par la structure d'entraînement. Un décalage angulaire d'axe (19a) de roulettes (19) permet une rotation en hélice autour du tube.
