Description
Verfahren zurr Einziehen von Drähten in Leitungsrohre Die Erfindung bezieht sich auf ein Verfahren zum Einziehen von Drähten in Leitungsrohre und ist dadurch gekennzeichnet, daß ein im Leitungsrohr leicht beweglicher Pfropfen, an dem ein Ende einer dünnen Leine befestigt ist, mit Hilfe eines auf dem Pfropfen einwirkenden Druckes durch das Leitungsrohr hindurchbefördert wird, und die in dieses einzuziehenden Drähte am anderen Leinenende befestigt und somit in das Leitungsrohr eingezogen werden. Vorzugsweise wird das Verfahren zum Einziehen von elektrischen L.eitun,-sdrähten verwendet. Das Druckgefälle kann beispielsweise in der Weise erzeugt werden, daß das dem einzuführenden Pfropfen abgekehrte Ende des Leitungsrohres an eine Unterdruckquelle anaeschlos-:en wird, wobei dann der Pfropfen durch den Druck der Atmosphäre durch das Leitungsrohr hindurch befördert wird. Eine andere Möglichkeit zur Erzeugung des Druckgefälles besteht darin. da.ß man ein T)rlirkrnedium von größerem als atmosphärischem Druck auf_ den Pfropfen einwirken läßt.Method of pulling wires into conduit The invention refers to a method of pulling wires into conduit and is characterized in that a plug, which is easily movable in the conduit pipe, is on to which one end of a thin line is attached, with the help of one on the stopper acting pressure is conveyed through the conduit pipe, and in this The wires to be drawn in are attached to the other end of the line and thus into the conduit to be withdrawn. Preferably the method of pulling in electrical L.eitun, wires used. The pressure gradient can for example be generated in this way that the end of the conduit pipe facing away from the plug to be inserted a vacuum source is connected, in which case the plug is caused by the pressure the atmosphere is conveyed through the conduit. Another possibility to generate the pressure gradient is. that one has a fluid medium of greater magnitude can act as atmospheric pressure on the plug.
Als Druckmedium zum Hindurchlassen des Pfropfens durch das Leitungsrohr kommt hauptsächlich Druckluft in Frage. welche einer beliebigen Druckluftquelle, beispielsweise einer Druckluftflasche, einer Luftpumpe oder einem Kompressor entnommen werden kann. Statt Druckluft kann selbstverständlich auch in an sich bekannter Weise ein anderes aasförmiges Druckmedium zur Verwendung gelangen. Da-, Druckmedium kann aber auch durch Entzünden der Ladung einer an das eine Leitungsende anzusetzenden Patrone erzeugt werden.As a pressure medium to allow the plug to pass through the conduit pipe compressed air is the main option. which any compressed air source, for example, taken from a compressed air cylinder, an air pump or a compressor can be. Instead of compressed air, it is of course also possible in a manner known per se another carrion-like pressure medium can be used. Because, print medium can but also by igniting the charge to be attached to one end of the line Cartridge are generated.
7-\-fit Hilfe des geschilderten Verfahrens können zum Beispiel elektrische Leitungsdrähte rasch und mühelos in die zugehörigen Leitungsrohre eingezogen werden. Bei den bisher bekannten Verfahren benutzte man ein Einziehband, das von dem Monteur mühevoll durch das Rohr gezogen werden muß.7 - \ - fit using the method described can, for example, electrical Line wires can be drawn into the associated line pipes quickly and easily. In the previously known method, a fish tape was used by the fitter must be laboriously pulled through the pipe.
In einigen Fällen, insbesondere dann, wenn das Leitungsrohr an eine Unterdruckquelle angeschlossen tvird und das Leitungsrohr nicht eine allzu große Länge und keine starken Krümmungen aufweist, kann auf die Anwendung eines Pfropfens verzichtet werden, indem es möglich ist, die dünne und leichte Leine durch Saugwirkung durch das Rohr hindurch zu befördern.In some cases, especially when the conduit is attached to a Vacuum source is connected and the conduit pipe is not an overly large one Length and no sharp curvatures, the application of a plug can can be dispensed with by making it possible to pull the thin and light leash by suction to convey through the pipe.
