Abstract

L'invention concerne une machine de nettoyage de tube et de canal (1). La machine de nettoyage de tube et de canal (1) présente un arbre creux (2) de rotor monté de manière à pouvoir tourner autour d'un axe de rotation (4) et un système de mâchoires de serrage (3) relié ou pouvant être relié à l'arbre creux (2) de rotor. Une spirale de nettoyage (6) peut être guidée à travers l'arbre creux (2) de rotor et une ouverture axiale (7) du système de mâchoires de serrage (3). L'arbre creux (2) de rotor peut être mis en rotation par un dispositif d'entraînement motorisé (12) en liaison fonctionnelle avec l'arbre creux (2) de rotor. En mode nettoyage, le système de mâchoires de serrage (3) peut être amené en contact de serrage avec la spirale de nettoyage (6) guidée à travers l'ouverture axiale (7). Pendant le mode nettoyage, la spirale de nettoyage (6) peut être mise en rotation avec l'arbre creux (2) de rotor, mis en rotation par l'unité d'entraînement motorisée (12), par le système de mâchoires de serrage (3) s'insérant avec serrage dans la spirale de nettoyage (6). Un axe de rotation (14) d'entraînement de l'unité d'entraînement motorisée (12) coïncide avec l'axe de rotation (4).
