Title (EN) FEED DEVICE AND CLEANING DEVICE
(FR) DISPOSITIF D'AVANCE ET APPAREIL DE NETTOYAGE
(DE) VORSCHUBEINRICHTUNG UND REINIGUNGSGERÄT
Abstract:
(EN) The invention relates to a feed device (1) for a cleaning spring (6) of a pipe-cleaning device which can rotate about its longitudinal axis (5). The feed device (1) has a main body (2) and a guide-through opening (4) arranged in the main body (2), through which the cleaning spring (6) can be guided, lengthways in a longitudinal direction (7) of the guide-through opening (4). The feed device (1) has at least two feed elements (8) arranged on the main body (2) such that they are secured in the longitudinal direction (7), which can be pressed onto the cleaning spring (6) in the guide-through opening (4) in such a way that a feeding through of the cleaning spring (6) is generated when said cleaning spring (6) rotates. At least one of the feed elements (8) is configured as an interlocking element (9) and has an interlocking part (11) oriented in the direction of the guide-through opening (4). The interlocking part (11) engages into the cleaning spring (6) interlockingly between windings (12) of the cleaning spring (6), if the feed element (8) is pressed onto the cleaning spring (6).
(FR) L'invention concerne un dispositif d'avance (1) pour une spirale de nettoyage (6) d'un appareil de nettoyage de tuyaux pouvant tourner autour de son axe longitudinal (5). Le dispositif d'avance (1) comprend un corps de base (2) et une ouverture de passage (4) disposée dans le corps de base (2), à travers laquelle la spirale de nettoyage (6) peut être passée dans une direction longitudinale (7) de l'ouverture de passage (4). Le dispositif d'avance (1) comprend au moins deux éléments d'avance (8) montés de manière fixe au corps de base (2) dans la direction longitudinale (7), qui peuvent être pressés contre la spirale de nettoyage (6) dans l'ouverture de passage (4) de telle façon qu'une avance de la spirale de nettoyage (6) est générée lorsque la spirale de nettoyage (6) tourne. Au moins un des éléments d'avance (8) est conçu en tant qu'élément d'adhérence par forme (9) et comprenant une partie d'adhérence par forme (11) orientée dans la direction de l'ouverture de passage (4). La partie d'adhérence par forme (11) s'engage par compatibilité de forme entre des spires (12) de la spirale de nettoyage (6) dans la spirale de nettoyage (6), lorsque les éléments d'avance (8) sont pressés contre la spirale de nettoyage (6).
(DE) Die Erfindung betrifft eine Vorschubeinrichtung (1) für eine um ihre Längsachse (5) rotierbare Reinigungsspirale (6) eines Rohrreinigungsgeräts. Die Vorschubeinrichtung (1) weist einen Grundkörper (2) und eine in dem Grundkörper (2) angeordnete Durchführungsöffnung (4) auf, durch welche die Reinigungsspirale (6) in einer Längsrichtung (7) der Durchführungsöffnung (4) längs hindurchführbar ist. Die Vorschubeinrichtung (1) weist mindestens zwei an dem Grundkörper (2) in der Längsrichtung (7) fixiert angeordnete Vorschubelemente (8) auf, die in der Durchführungsöffnung (4) derart an die Reinigungsspirale (6) andrückbar sind, dass bei rotierender Reinigungsspirale (6) ein Vorschub der Reinigungsspirale (6) erzeugt wird. Mindestens eines der Vorschubelemente (8) ist als Formschlusselement (9) ausgestaltet und weist ein in Richtung der Durchführungsöffnung (4) ausgerichtetes Formschlussteil (11) auf. Das Formschlussteil (11) greift formschlüssig zwischen Windungen (12) der Reinigungsspirale (6) in die Reinigungsspirale (6) ein, wenn die Vorschubelemente (8) an die Reinigungsspirale (6) angedrückt sind.
