Abstract
Description
Die Erfindung betrifft eine Federwelle für die Reinigung von Rohrleitungen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a spring shaft for cleaning pipelines according to the preamble of claim 1.
Derartige Federwellen, die auch als "Reinigungsspiralen" bezeichnet werden, bestehen üblicherweise aus einem gewendelten, gezogenen Stahldraht mit rundem Querschnitt und glatter Oberfläche. Sie werden an ihrem Ende über Anschlußkupplungen mit den unterschiedlichsten Werkzeugen versehen wie Bohrern, Schneidköpfen, Kettenschleuderköpfen, Rohrbürsten, Wurzelschneidern, Schlammbohrern etc. Die Antriebsmaschinen und ihre Wirkungsweise werden in der Detailbeschreibung näher erläutert.Such spring shafts, also called "cleaning spirals" usually consist of a coiled, drawn Steel wire with a round cross-section and a smooth surface. You will be on at the end via connecting couplings with a wide variety of tools provided like drills, cutting heads, chain slingshot heads, Pipe brushes, root cutters, mud drills etc. The drive machines and their mode of operation are described in the detailed description explained in more detail.
Die bekannten Federwellen haben also im wesentlichen nur Antriebscharakter. Die angesetzten Werkzeuge werden durch die Federwelle, die auch aus mehreren Federwellen zusammengesetzt sein kann, in verstopfte Rohrleitungen eingebracht, wobei sie sich auch durch Krümmer, Rohrabzweigungen etc. "hindurcharbeiten". Der Rückzug erfolgt durch Umkehr der Drehrichtung, wobei bei hartnäckigen Verstopfungen auch periodische Vorwärts- und Rückzugsbewegungen ausgeführt werden können. The known spring shafts have essentially only drive character. The tools used are by the spring shaft, the can also be composed of several spring shafts, in clogged Pipelines introduced, whereby they are also through elbows, pipe branches etc. "work through". The withdrawal is done by repentance the direction of rotation, with persistent blockages also periodic Forward and retreat movements can be performed.
Durch die DE 38 32 716 C2 ist eine Federwelle mit einem Querschnitt in Form eines Rechtecks oder Trapezes bekannt, von dem zwei gegenüber liegende Kanten parallel zur Achse der Federwelle verlaufen. Die äußere dieser schraubenlinienförmig verlaufenden Kanten liegt in einer imaginären Zylinderfläche, wenn man die gestreckte Lage der Federwelle betrachtet. Dadurch können die gleichfalls schraubenlinienförmig verlaufenden Ecken dieses Querschnitts keine reinigende Wirkung auf die Innenwände von Rohren ausüben, auch dann nicht, wenn die Federwelle durch Rohrbögen oder Krümmer hindurchgeführt wird, weil in diesen Falle die äußere Kante des Querschnitts den Rohrbogen auf seinem kleinsten Krümmungsradius nur tangential berührt, die Querschnittskanten im Rohrbogen also nicht in Berührung mit der Rohrinnenfläche kommen können.DE 38 32 716 C2 is a spring shaft with a cross section in Known form of a rectangle or trapezoid, of which two are opposite lying edges run parallel to the axis of the spring shaft. The outer these helical edges lie in an imaginary Cylinder surface if you consider the straight position of the spring shaft. This means that the corners, which also run in a helical shape, can this cross section does not have a cleaning effect on the inner walls of Exercise pipes, even if the spring shaft through pipe bends or elbow is passed through, because in this case the outer edge of the cross-section the pipe bend at its smallest radius of curvature only touches tangentially, so the cross-sectional edges in the pipe bend are not in Can come into contact with the inner surface of the pipe.
Die bekannte Vorrichtung dient zum Auskleiden der Innenwände von Rohren, und am Ende der Federwelle sind hintereinander mehrere rotationssymmetrische Verteilungskörper für ein flüssiges Beschichtungsmaterial angeordnet, das durch einen Schlauch, der innerhalb der Federwelle verläuft, zugeführt und beim Rückzug der Federwelle durch die Verteilungskörper auf der Rohrwand verteilt wird. Die Federwelle hat nur eine Antriebsfunktion: Aus Gründen der Beschränkung von Durchmesseränderungen beim Vorwärts- und Rückwärtsdrehen der Federwelle hat diese einen durch Formeln definierten rechteckigen oder trapezförmigen Querschnitt. Die Verwendung der Federwelle selbst als Reinigungsvorrichtung ist weder offenbart noch nahegelegt, zumal ausdrücklich angegeben ist, das zum Reinigen der Rohrinnenwand am vorderen Ende der Federwelle Reinigungsvorrichtungen angebracht werden müssen.The known device is used to line the inner walls of Tubes, and at the end of the spring shaft there are several in a row rotationally symmetrical distribution body for a liquid coating material arranged by a hose inside the spring shaft runs, fed and when the spring shaft retracts through the Distribution body is distributed on the pipe wall. The spring shaft only has a drive function: for reasons of limitation of diameter changes when turning the spring shaft forwards and backwards these have a rectangular or trapezoidal shape defined by formulas Cross-section. The use of the spring shaft itself as a cleaning device is neither disclosed nor suggested, especially since it is expressly stated is for cleaning the inner wall of the pipe at the front end of the spring shaft Cleaning devices must be attached.
Der Erfindung liegt die Aufgabe zugrunde, derartige Federwellen dahingehend zu verbessern, daß sie unter Beibehaltung ihrer Antriebsfunktion selbst eine Reinigungswirkung ausüben können.The object of the invention is to provide such spring shafts to improve it while maintaining its drive function can have a cleaning effect themselves.
Die Lösung der gestellten Aufgabe erfolgt erfindungsgemäß durch die Merkmale im Kennzeichen des Patentanspruchs 1.According to the invention, the object is achieved by Features in the characterizing part of patent claim 1.
Durch diese Lösung wird die gestellte Aufgabe in vollem Umfange gelöst, d.h., die Federwellen können unter Beibehaltung ihrer Antriebsfunktion selbst eine Reinigungswirkung ausüben und schaben gewissermaßen auch hartnäckige Verkrustungen von den Rohrwänden ab, die aus Keramiken, Gußeisen oder Kunststoff bestehen können.With this solution, the task is solved in full, i.e. the spring shafts can maintain their drive function themselves have a cleaning effect and to a certain extent also scrape stubborn incrustations from the tube walls, which are made of ceramics, Cast iron or plastic can exist.
