Die Erfindung betrifft eine Vorrichtung zum Reinigen von Rohren mit einem druckluftbetriebenem Werkzeug, das an einem Ende eines druckluftführenden, rotierend und in achsialer Richtung angetriebenen, flexiblen Hochdruckschlauches befestigt ist.The invention relates to a device for cleaning pipes with a compressed air-operated tool that is attached to one end of a flexible high-pressure hose that carries compressed air and is driven in a rotating and axial direction.
Bei der Reinigung von Rohren, insbesondere von Kanalrohren, Drainrohren und dergleichen werden oft sehr harte und spröde Inkrustrierungen festgestellt, die gelöst werden müssen. Dazu ist eine Vorrichtung der eingangs beschriebenen Gattung bekannt (DE-Gbm 91 14 022), bei der ein druckluf tbetriebenes Schlagwerkzeug am Ende eines Hochdruckschlauches befestigt ist. Der Hochdruckschlauch weist einen Drehantrieb auf und wird durch eine Vorschubeinheit geführt, die vorzugsweise mit einstellbarer Achsialkraft arbeitet. Damit kann die Bewegung des Schlagwerkzeuges in dem zu reinigenden Rohr kontrolliert und auch gesteuert werden. Eine solche Vorrichtung läßt sich über Rohrlängen von mehreren 100 m einsetzen, sie ist auch kurvengängig. Der Hochdruckschlauch muß außer der Achsialkraft auch ein Drehmoment übertragen, um die Summe aller Reibkräfte überWhen cleaning pipes, especially sewer pipes, drain pipes and the like, very hard and brittle incrustations are often found that must be removed. For this purpose, a device of the type described above is known (DE-Gbm 91 14 022), in which a compressed air-operated impact tool is attached to the end of a high-pressure hose. The high-pressure hose has a rotary drive and is guided through a feed unit that preferably works with adjustable axial force. This allows the movement of the impact tool in the pipe to be cleaned to be monitored and controlled. Such a device can be used over pipe lengths of several 100 m, and it can also be used on curves. In addition to the axial force, the high-pressure hose must also transmit a torque in order to distribute the sum of all friction forces over

die gesamte Reinigungstiefe zu überwinden. Dabei können auch Drehmomentspitzen auftreten. Um zu verhindern, daß der Hochdruckschlauch unter der Wirkung des Drehmomentes Schlaufen bildet, wird er zumindest in einem Bereich zwischen der Vorschubeinheit und dem Rohreintritt in einem Führungsschlauch geführt, der das Ausknicken des Hochdruckschlauches unterbindet. Ein solcher Führungsschlauch kann aber nicht über die gesamte Länge des Hochdruckschlauches angeordnet werden.to overcome the entire cleaning depth. Torque peaks can also occur. To prevent the high-pressure hose from forming loops under the effect of the torque, it is guided in a guide hose at least in an area between the feed unit and the pipe inlet, which prevents the high-pressure hose from kinking. However, such a guide hose cannot be arranged over the entire length of the high-pressure hose.
Aufgabe der Erfindung ist es, bei einer Vorrichtung der eingangs beschriebenen Gattung die Stabilität des Hochdruckschlauches zu verbessern.The object of the invention is to improve the stability of the high-pressure hose in a device of the type described above.
Diese Aufgabe wird gelöst mit einer Vorrichtung der eingangs beschriebenen Gattung, die gekennzeichnet ist durch einen in den Hochdruckschlauch einführbaren, glasfaserverstärkten Kunststoffstab. Ein solcher Stab, der auch aus mehreren hintereinander in den Hochdruckschlauch einführbaren Kunststoffstäben bestehen kann, verbessert die Stabilität des Hochdruckschlauches ganz erheblich, so daß der Hochdruckschlauch auch bei großen Drehmomentbelastungen nicht ausknickt bzw. keine Schlaufen wirft. Weil der Schlauch für Transport- und Lagerzwecke aufgewickelt werden muß, kann der glasfaserverstärkte Kunststoffstab, bzw. können die Kunststoffstäbe bei Transport und Lagerung nicht im Hochdruckschlauch verbleiben. Sie müssen vor Beginn der Reinigungsarbeit in den Hochdruckschlauch eingeführt werden und nach Beendigung der Arbeit wieder daraus entfernt werden.This task is solved with a device of the type described at the beginning, which is characterized by a glass fiber reinforced plastic rod that can be inserted into the high pressure hose. Such a rod, which can also consist of several plastic rods that can be inserted into the high pressure hose one after the other, improves the stability of the high pressure hose considerably, so that the high pressure hose does not bend or form loops even under high torque loads. Because the hose has to be wound up for transport and storage purposes, the glass fiber reinforced plastic rod or the plastic rods cannot remain in the high pressure hose during transport and storage. They must be inserted into the high pressure hose before cleaning work begins and removed again after work is finished.
Es versteht sich, daß die Stabilität des Hochdruckschlau-It is understood that the stability of the high pressure hose

ches um so größer wird, je größer der Querschnitt und damit das Widerstandsmoment des glasfaserverstärkten Kunststoff Stabes ist. Bei Verwendung druckluftbetriebener Werkzeuge muß der Querschnitt des Kunststoffstabes aber kleiner sein als der Innenquerschnitt des Hochdruckschlauches bzw. kleiner sein als der Innenquerschnitt von zugeordneten Schlauchkupplungen, damit das druckluftbetriebene Werkzeug noch mit Druckluft versorgt werden kann. Bei Verwendung anderer Werkzeuge können auch Kunststoffstäbe eingesetzt werden, deren Querschnitt dem Innenquerschnitt des Hochdruckschlauches entspricht.ches becomes larger the larger the cross section and thus the section modulus of the glass fiber reinforced plastic rod is. When using compressed air-operated tools, the cross section of the plastic rod must be smaller than the inner cross section of the high pressure hose or smaller than the inner cross section of the associated hose couplings so that the compressed air-operated tool can still be supplied with compressed air. When using other tools, plastic rods can also be used whose cross section corresponds to the inner cross section of the high pressure hose.
Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigen:In the following, an embodiment of the invention is explained, as shown in the drawing; in which:
Fig. 1 schematisch eine Vorrichtung zum Reinigen von Kanalrohren,Fig. 1 schematically shows a device for cleaning sewer pipes,
Fig. 2 teilweise einen Längsschnitt durch einen Hochdruckschlauch mit zugeordneter Schlauchkupplung.Fig. 2 shows a partial longitudinal section through a high-pressure hose with associated hose coupling.
Auf einem in Richtung des Pfeils 1 verschieblichen Wagen 2 ist ein Drehantrieb 3 für einen flexiblen Hochdruckschlauch 4 angeordnet. Dem Hochdruckschlauch 4 wird in einer Drehdurchführung 5 Druckluft aus einer Druckluftleitung 6 zugeführt. Der Hochdruckschlauch 4 erstreckt sich dann durch eine zweiteilig ausgebildete Vorschubeinheit 7, 8, mit der eine einstellbare Achsialkraft auf den Hochdruckschlauch 4 aufgebracht werden kann. Mit dem Teil 7 kann eine Rückzugskraft und mit dem Teil 8 eine Vorschubkraft aufgebracht werden.A rotary drive 3 for a flexible high-pressure hose 4 is arranged on a carriage 2 that can be moved in the direction of arrow 1. Compressed air from a compressed air line 6 is supplied to the high-pressure hose 4 in a rotary feedthrough 5. The high-pressure hose 4 then extends through a two-part feed unit 7, 8, with which an adjustable axial force can be applied to the high-pressure hose 4. Part 7 can be used to apply a retraction force and part 8 can be used to apply a feed force.

Im Anschluß daran ist der flexible Hochdruckschlauch 4 innerhalb eines flexiblen Führungsschlauchs 9 angeordnet, der sich im Anschluß an die stationäre Vorschubeinheit 7, 8 durch einen Schacht 10 bis zum Anfang 11 des zu reinigenden Rohres 12 erstreckt. Innerhalb des Rohres 12 ist auf den rotierenden, flexiblen Hochdruckschlauch 4 zumindest ein Stützring 13 aufgesetzt, der sich im Abstand von einem am Ende des Hochdruckschlauches 4 angeordneten Schlagwerkzeug 14 befindet. Das Schlagwerkzeug 14 arbeitet pneumatisch mit der durch den Hochdruckschlauch 4 zugeführten Druckluft. Durch die schlagende Bewegung des Schlagwerkzeuges 14 können feste Inkrustrierungen 15 des Rohres 12 gelöst werden.The flexible high-pressure hose 4 is then arranged within a flexible guide hose 9, which extends from the stationary feed unit 7, 8 through a shaft 10 to the beginning 11 of the pipe 12 to be cleaned. Inside the pipe 12, at least one support ring 13 is placed on the rotating, flexible high-pressure hose 4, which is located at a distance from an impact tool 14 arranged at the end of the high-pressure hose 4. The impact tool 14 works pneumatically with the compressed air supplied through the high-pressure hose 4. The striking movement of the impact tool 14 can loosen solid incrustations 15 of the pipe 12.
Wie man aus Fig. 2 entnimmt, ist in den Hochdruckschlauch 4 und ggf. vorhandene Schlauchkupplungen 16 ein glasfaserverstärkter Kunststoffstab 17 eingeführt, der die Stabilität des Hochdruckschlauches 4 verbessert. Bei größeren Längen des Hochdruckschlauches 4 empfiehlt es sich, mehrere glasfaserverstärkte Kunststoffstäbe hintereinander in den Hochdruckschlauch 4 einzuführen. Der Querschnitt des Kunststoffstabes 17 ist kleiner als der Innenquerschnitt des Hochdruckschlauches 4 bzw. der vorhandenen Schlauchkupplung 16, damit die Druckluft ungehindert zum Schlagwerkzeug 14 fließen kann.As can be seen from Fig. 2, a glass fiber reinforced plastic rod 17 is inserted into the high pressure hose 4 and any hose couplings 16 that are present, which improves the stability of the high pressure hose 4. For longer high pressure hoses 4, it is recommended to insert several glass fiber reinforced plastic rods one after the other into the high pressure hose 4. The cross section of the plastic rod 17 is smaller than the inner cross section of the high pressure hose 4 or the existing hose coupling 16, so that the compressed air can flow unhindered to the impact tool 14.
Für Transport- und Lagerzwecke wird der Hochdruckschlauch 4 in der Regel aufgewickelt. Die dazu erforderliche Krümmung kann von den Kunststoffstäben 17 nicht aufgenommen werden. Deswegen werden die Kunststoffstäbe 17 vor Beginn der Reinigungsarbeiten in den gestreckten Hochdruckschlauch 17 eingeführt und nach Beendigung der Reinigungs-For transport and storage purposes, the high-pressure hose 4 is usually wound up. The curvature required for this cannot be accommodated by the plastic rods 17. Therefore, the plastic rods 17 are inserted into the stretched high-pressure hose 17 before cleaning work begins and are removed after cleaning work has been completed.
