Abstract

L'invention concerne une machine de nettoyage des tuyauteries et des canalisations (1). Ladite machine comprend un système de mâchoires de serrage (3) monté en rotation et servant à bloquer par serrage une spirale de nettoyage (10). Le système de mâchoires de serrage (3) est amené en rotation par un dispositif d'entraînement (4) motorisé pendant que la machine de nettoyage des tuyauteries et des canalisations (1) fonctionne en mode nettoyage. Le système de mâchoires de serrage (3) peut être actionné par un levier à main (5). La spirale de nettoyage (10) est bloquée par serrage dans le système de mâchoires de serrage (3) lorsque le levier à main (5) est actionné, de sorte que la spirale de nettoyage (10) est amenée en rotation. La machine de nettoyage des tuyauteries et des canalisations (1) comporte un dispositif de sécurité (12) qui coopère avec le levier à main (5) et qui peut être désactivé par un actionnement du levier à main (5). Le système de mâchoires de serrage (3) se trouve dans un état de repos et le fonctionnement en mode nettoyage de la machine de nettoyage des tuyauteries et des canalisations (1) est interrompu lorsque le dispositif de sécurité (12) est activé. Le système de mâchoires de serrage (3) est amené en rotation et le fonctionnement en mode nettoyage de la machine de nettoyage des tuyauteries et des canalisations (1) redémarre lorsque le dispositif de sécurité (12) est désactivé.
