Abstract
Vorrichtung zum Druckprüfen eines an einen Hauptkanal (2) angeschlossenen Nebenkanals (20) einschließlich des Anschlussbereichs, mit einem an seinen Enden verschlossenen, zwischen einem vorderen Fahrteil (11) und einem hinteren Fahrteil (12) angeordneten Trägerrohr (4), das mit einer Durchbrechung und mit einer in seinem Lumen schräg verlaufenden, an die Durchbrechung anschließenden Leiteinrichtung (7) zum Einführen einer von einem Verschiebeschlauch (19) getragenen Abdichteinheit (1) in den Nebenkanal (20), und mit gegen die Innenwand des Hauptkanals (2) wirkenden Abdichtelementen (3) versehen ist, dadurch gekennzeichnet, dass das die Abdichtelemente (3) tragende Trägerrohr (10) an den beiden Fahrteilen (11,12) über Drehlager (10) gelagert ist und die Leiteinrichtung (7) fest mit dem Trägerrohr (4) verbunden ist.Device for pressure testing a secondary channel (20) connected to a main channel (2) including the connection area, with a carrier tube (4) which is closed at its ends and is arranged between a front running part (11) and a rear running part (12) and has an opening and with a guide device (7) which runs obliquely in its lumen and adjoins the opening for introducing a sealing unit (1) carried by a sliding hose (19) into the secondary channel (20), and with sealing elements acting against the inner wall of the main channel (2) (3), characterized in that the carrier tube (10) carrying the sealing elements (3) is mounted on the two running parts (11, 12) via pivot bearings (10) and the guide device (7) is fixed to the carrier tube (4) connected is.
Description
Die Erfindung betrifft eine Vorrichtung zum Druckprüfen eines an einen Hauptkanal angeschlossenen Nebenkanals einschließlich des Anschlussbereichs, mit einem an seinen Enden verschlossenen, zwischen einem vorderen Fahrteil und einem hinteren Fahrteil angeordneten Trägerrohr, das mit einer Durchbrechung und mit einer in seinem Lumen schräg verlaufenden an die Durchbrechung anschließenden Leiteinrichtung zum Einführen einer mit einem Verschiebeschlauch versehenen Abdichteinheit in den Nebenkanal und mit gegen die Innenwand des Hauptkanals wirkenden Abdichtelementen versehen ist.The invention relates to a device for pressure testing of a secondary channel connected to a main channel including the connection area, with a closed at its ends, arranged between a front drive part and a rear drive member support tube having an opening and with an inclined in its lumen to the opening subsequent guide means for introducing a sealing tube provided with a sealing unit is provided in the secondary channel and acting against the inner wall of the main channel sealing elements.

Eine ähnliche Ausgestaltung ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Druckprüfen eines an einen Hauptkanal angeschlossenen Nebenkanals einschließlich des Anschlussbereiches zu schaffen, bei welcher die beweglichen Komponenten besser gegen Beschädigung und Verunreinigung geschützt sind.The invention has for its object to provide a device for pressure testing a secondary channel connected to a main channel including the connection area, in which the movable components are better protected against damage and contamination.
Diese Aufgabe wird durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen.This object is achieved by a device having the features specified in claim 1. Preferred embodiments will be apparent from the dependent claims.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Trägerrohr von den beiden Fahrteilen über Drehlager getragen wird, und die Leiteinrichtung fest mit dem Trägerrohr verbunden ist, sodass das Trägerrohr vor dem Hinausschieben des Abdichtelements in den Nebenkanal in eine mit diesem fluchtende Position gedreht werden kann, woraufhin die Abdichtelemente aufgeblasen werden.According to the invention this object is achieved in that the support tube is supported by the two driving parts via pivot bearings, and the guide is firmly connected to the support tube, so that the support tube can be rotated before the pushing out of the sealing element in the secondary channel in a position aligned with this whereupon the sealing elements are inflated.
Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindungen an.The dependent claims indicate advantageous embodiments of the invention.
Die vorgeschlagene Ausbildung ermöglicht es, die Durchbrechung des Trägerrohres nur so groß auszubilden, dass sie die Durchführung der Abdichteinheit ermöglicht, indem das Trägerrohr gegen das Fahrgestell, nicht aber wie im Stand der Technik die Leiteinrichtung gegen das Trägerrohr verdreht wird.The proposed embodiment makes it possible to form the opening of the support tube only so large that it allows the implementation of the sealing unit by the support tube against the chassis, but not as in the prior art, the guide is rotated against the support tube.
Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert, in der schematisch in einer Schnittdarstellung ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung wiedergegeben ist.The invention will be explained below with reference to a drawing in which an embodiment of the device according to the invention is shown schematically in a sectional view.
