Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen, insbesondere von kleinkalibrigen Rohren, mit einem rotierend um seine Achse angetriebenen Hochdruckschlauch, der an seinem vorderen Ende wenigstens eine Düse für den Austritt der Reinigungsflüssigkeit aufweist.The invention relates to a device for cleaning, in particular small-bore pipes, with a high-pressure hose which is driven in rotation about its axis and which has at least one nozzle at its front end for the exit of the cleaning liquid.

Eine derartige Vorrichtung ist bekannt (DE-GM 81 35 474). Die bekannte Vorrichtung hat sich an sich bewährt. Probleme können allerdings entstehen, wenn kleinkalibrige Rohre gereinigt werden sollen und dazu ein Hochdruckschlauch mit verhältnismäßig kleinem Außendurchmesser eingesetzt werden muß. Dann besteht nämlich die Gefahr, daß das vordere, mit der Düse versehene Ende des Hochdruckschlauches im Rohr blockiert wird, während der Drehantrieb für den Hochdruckschlauch weiterarbeitet. Im Hochdruckschlauch können sich dann Schlingen bilden, und unter ungünstigen Bedingungen kann der Hochdruckschlauch auch reißen oder brechen.Such a device is known (DE-GM 81 35 474). The known device has proven itself. Problems can arise, however, if small-caliber pipes are to be cleaned and a high-pressure hose with a relatively small outside diameter has to be used for this. Then there is the danger that the front end of the high-pressure hose, which is provided with the nozzle, is blocked in the pipe while the rotary drive for the high-pressure hose continues to work. Loops can then form in the high-pressure hose and, under unfavorable conditions, the high-pressure hose can also tear or break.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs beschriebenen Gattung so zu verbessern, daß sie sich insbesondere zum Reinigen kleinkalibriger Rohre oder zum Reinigen von Gegenständen mit kleinkalibrigen Öffnungen eignet.The object of the invention is to improve a device of the type described above so that it is particularly suitable for cleaning small-caliber pipes or for cleaning objects with small-caliber openings.

Diese Aufgabe wird dadurch gelöst, daß der Hochdruckschlauch in einem drehfesten Schutzschlauch geführt ist, dessen eines Ende mit dem Rohr oder mit einer Drehdurchführung für eine mit dem Hochdruckschlauch gekuppelte Lanze verbindbar ist. Der Schutzschlauch kann zusammen mit dem Hochdruckschlauch eine an sich beliebige Länge aufweisen. Er bildet eine Führung für den kleinkalibrigen Hochdruckschlauch, der dadurch nicht nur gegen Abdrehen, sondern auch gegen Verschlingung geschützt ist. Nichtsdestoweniger ist das System aus Hochdruckschlauch und Schutzschlauch flexibel, so daß es möglich ist, den Hochdruckschlauch zusammen mit dem Schutzschlauch in einem Bogen zu führen. Es ist lediglich erforderlich, daß der Schutzschlauch eine hinreichende Biegesteifigkeit hat. Vorzugsweise soll der Schutzschlauch eine größere Biegesteifigkeit besitzen als der Hochdruckschlauch. Im übrigen kann der Innendurchmesser des Schutzschlauches bis zu 30 x so groß sein wie der Außendurchmesser des Hochdruckschlauches.This object is achieved in that the high-pressure hose is guided in a non-rotatable protective hose, one end of which can be connected to the tube or to a rotary leadthrough for a lance coupled to the high-pressure hose. The protective tube together with the high-pressure tube can have any length per se. It forms a guide for the small-caliber high-pressure hose, which is not only protected against twisting, but also against entanglement. Nevertheless, the system of high-pressure hose and protective hose is flexible, so that it is possible to guide the high-pressure hose together with the protective hose in an arc. It is only necessary that the protective tube has sufficient flexural rigidity. The protective hose should preferably have greater flexural rigidity than the high-pressure hose. In addition, the inner diameter of the protective hose can be up to 30 times as large as the outer diameter of the high-pressure hose.

Wird die Vorrichtung zum Reinigen von Rohren eingesetzt, dann ist in der Regel dem Antrieb eine auf den Hochdruckschlauch einwirkende Einrichtung zum Erzeugen eines Vorschubs nachgeschaltet. In diesem Fall kann der Schutzschlauch drehfest mit der Einrichtung verbunden sein und kann zwischen dem Antrieb und der Einrichtung ein großkalibriger Hochdruckschlauch angeordnet sein, der sich bis in den Schutzschlauch hinein erstreckt und dort mit dem kleinkalibrigen Hochdruckschlauch gekuppelt ist. Mit dem großkalibrigen Hochdruckschlauch erreicht man außerhalb des Schutzschlauches eine hohe Arbeitssicherheit, so daß auch bei hohen Drücken keine Schlauchbrüche auftreten. Der großkalibrige Hochdruckschlauch besitzt im übrigen eine hinreichende Stabilität, so daß er auf der Strecke zwischen dem Antrieb und der Einrichtung zum Erzeugen des Vorschubs keine Schleifen oder Schlingen bildet. Unter der Wirkung zum Erzeugen des Vorschubs wird der großkalibrige Hochdruckschlauch in den Schutzschlauch eingezogen oder eingeschoben und schiebt dabei den kleinkalibrigen Hochdruckschlauch über das mit dem zu reinigenden Rohr verbundene Ende des Schutzschlauches in das zu reinigende Rohr hinein. Im Ergebnis entsteht in axialer Richtung ein starres System, welches auch bei Betriebsstörungen verhindert, daß der in das Rohr eingeführte kleinkalibrige Hochdruckschlauch aus dem Rohr herausgedrückt wird.If the device is used for cleaning pipes, the drive is usually followed by a device acting on the high-pressure hose for generating a feed. In this case, the protective tube can be connected to the device in a rotationally fixed manner and can be between a large-caliber high-pressure hose can be arranged for the drive and the device, which extends into the protective hose and is coupled there to the small-caliber high-pressure hose. With the large-caliber high-pressure hose, a high level of work safety is achieved outside the protective hose, so that no hose breaks occur even at high pressures. The large-caliber high-pressure hose also has sufficient stability so that it does not form loops or loops on the line between the drive and the device for generating the feed. Under the effect of generating the feed, the large-caliber high-pressure hose is drawn into or inserted into the protective hose and pushes the small-caliber high-pressure hose over the end of the protective hose connected to the pipe to be cleaned into the pipe to be cleaned. The result is a rigid system in the axial direction, which prevents the small-caliber high-pressure hose inserted into the pipe from being pushed out of the pipe even in the event of malfunctions.

Die Vorrichtung kann aber auch im Handbetrieb zum Reinigen anderer Gegenstände, z.B. von Hohlkörpern eingesetzt werden. Dazu wird der Schutzschlauch drehfest im Bereich des Antriebs gehalten, während die Drehdurchführung für die Lanze ein tragbares Handgerät ist. Es versteht sich, daß das Handgerät so ausgebildet ist, daß es von einer Bedienungsperson sicher gehalten werden kann. Der Hochdruckschlauch ist im Schutzschlauch geführt und vor dem Handgerät mit der drehbaren Lanze gekuppelt, die an ihrem vorderen Ende die Austrittsdüsen für die Reinigungsflüssigkeit trägt. Die Lanze kann in eine Öffnung des Hohlkörpers oder dergleichen eingeführt werden, welches mit der aus den Düsen der Lanze austretenden Reinigungsflüssigkeit gereinigt wird.The device can also be used in manual operation for cleaning other objects, such as hollow bodies. For this purpose, the protective hose is held in the area of the drive in a rotationally fixed manner, while the rotating leadthrough is a portable hand-held device for the lance. It is understood that the handheld device is designed so that it can be held securely by an operator. The high-pressure hose is guided in the protective hose and in front of the handheld device with the rotating one Lance coupled, which carries the outlet nozzles for the cleaning liquid at its front end. The lance can be inserted into an opening in the hollow body or the like, which is cleaned with the cleaning liquid emerging from the nozzles of the lance.
