Gerätesatz zum Einbringen von Trockengleitmitteln in RohreEquipment set for introducing dry lubricants into pipes
Zum Einziehen von KaJbeln in Kabelkanalrohre wird üblicherweise das Kabel beim Einlaufen in das Kabelkanalrohr gefettet oder mit OeI bestrichen. Insbesondere bei der Verlegung von speziellen Kabeln, z.B. Glasfaserkabeln, werden in einem Arbeitsgang Kabel bis zu mehreren Kilometern Länge in Kabelkanalrohre eingezogen. Dabei streift sich durch die Reibung ies Kabels an der Rohrinnenwand mehr und mehr der zuvor aufgebrachte Fett- oder OeI-film ab und die Reibungswerte werden mit zunehmender Einziehlänge immer größer. To pull cables into cable ducts, the cable is usually greased or coated with oil as it runs into the cable duct. Especially when laying special cables, such as fiber optic cables, cables up to several kilometers in length are pulled into cable ducts in a single operation. As a result of the friction between the cable and the inner wall of the pipe, more and more of the previously applied grease or oil film is wiped off and the friction values increase with increasing length.
Um den Reibungswert des Kabels an der Innenwand des Kabelkanalrohres auf der gesamten Trassenlänge gering zu halten, verwendet man auch Trockengleitmittel, wie z.B. Micro-Kugeln aus Glas oder Kunststoff. Bevor das Kabel eingezogen wird, werden die Micro-Kugeln mit geeigneten Vorrichtungen derart in die Kabelkanalrohre eingebracht, daß sich das Gleitmittel (Micro-Kugeln) möglichst gleichmäßig auf der Rohrinnenwand über die gekirnte Kabel'.analr ohr länge verteilt. Hierdurch wird gewissermaßen eine "rollende Reibung" des Kabels an der Rohrinnenwand des Kabelkanalrohres während des gesamten Zugvorganges erreicht.To increase the coefficient of friction of the cable on the inner wall of the cable duct To keep the entire length of the route short, dry lubricants such as micro-spheres made of glass or plastic are also used. Before that Cable is drawn in, the micro-balls are inserted into the cable ducts with suitable devices in such a way that the lubricant (Micro-balls) as evenly as possible on the inner wall of the pipe over the churned Kabel'.anal tube length distributed. As a result, a "rolling friction" of the cable on the inner wall of the cable duct during the entire pulling process achieved.
Der Erfindungsgegenstand"Gerätesatz zum Einbringen von Trockengleitmitteln in Rohre" gewährleistet in besonderer Weise eine gleichmäßige Verteilung des Trockengleitmittels (Micro-Kugeln) in den Kabelkanalrohren über die gesamte Trassenlänge. Von einem handelsüblichen Kompressor wird Druckluft über das Kupplungsstück (1), den DruckirinUerer (2) mit Manomter (3) über eine weitere Kupplung (4) zu einem Injektor (5) geführt. Der Injektor (5) ist so ausgelegt, daß bei bestimmten Druckwerten, die am Druckminderer (2) eingestellt werden können, je nach Kabelkanalrohr-Purchmesser und -Länge ein Saugeffekt zum Txockengleitmittel (6) entsteht und das Trockengleitmittel über eine vorzugsweise flexible Leitung (7) und weiter über den Injektor (5) zum Leitungsstück (8) angesaugt und über die Kupplung (9) mit nachgeschaltetem Schlauch (10) und über die auf das Schutzrohr aufgesetzte Tülle (11) in das Schutsrohr eilvgeblasen wird. Der am Ende der Kabelkanalrohr-Trasse (12) ein-The subject of the invention "Equipment set for the introduction of dry lubricants in pipes "guarantees in a special way an even distribution of the dry lubricant (micro-balls) in the cable duct pipes over the entire length of the route. Compressed air is generated by a commercially available compressor Via the coupling piece (1), the pressure regulator (2) with manometer (3) another coupling (4) led to an injector (5). The injector (5) is designed so that at certain pressure values, which can be set on the pressure reducer (2), depending on the cable duct purchase and length a suction effect to the Txock lubricant (6) is created and the dry lubricant Sucked in via a preferably flexible line (7) and further via the injector (5) to the line piece (8) and via the coupling (9) with the downstream Hose (10) and through the grommet (11) placed on the protective tube into the protective tube. The one at the end of the cable duct route (12)
gesetzte, geschlitzte stopfen (iJ) mit entsprechender Düse bewirkt einen Staueffekt, so daß das Trockengleitmittel nicht ohne weiteres aus dem freien Rohrende herausgeblasen wird. Entsprechend den verschiedenen Kabel- j kanalrohr-Durchmessern können Adapter (14) an der geschlitzten Tülle (11) \ angebracht werden. Die Schwimmer scheibe (15), durch welche die flexible Leitung (7) gesteckt wird, bewirkt, daß sich zu der Mündung der flexiblen Leitung (7) ein Luftkegel (16) bildet, wodurch mit dem Trockengleitmittel auch immer eine gewisse Menge Luft durch den Saugschlauch strömt und somit eine Verstopfung der flexiblen Leitung (7) ausgeschlossen wird. Die Schwimmer scheibe (15) gleitet bei der Entnahme des Trockengleitmittels (6) automatisch auf der langsam absinkenden Oberfläche des Trockengleitmittels (6) im Behälter (17) langsam nach unten, wobei Markierungen in dem Behälter (17) die verbrauchte Trockengleitmittelmenge (6) anzeigen. Die Tülle (11) und der Stopfen (13) sind geschlitzt, damit beide Elemente über ein möglicherweise bereits im Kabelkanalrohr (12) liegendes Zugseil (18) greifen können. Set, slotted stopper (iJ) with a corresponding nozzle creates a damming effect so that the dry lubricant is not simply blown out of the free end of the pipe. Adapters (14) can be attached to the slotted grommet (11) according to the various cable duct pipe diameters. The float disc (15), through which the flexible line (7) is inserted, causes an air cone (16) to form at the mouth of the flexible line (7), whereby a certain amount of air always flows through the dry lubricant Suction hose flows and thus a blockage of the flexible line (7) is excluded. When the dry lubricant (6) is removed, the float disk (15) automatically slides slowly downwards on the slowly sinking surface of the dry lubricant (6) in the container (17), with markings in the container (17) indicating the amount of dry lubricant used (6) . The grommet (11) and the plug (13) are slotted so that both elements can grip a pull rope (18) possibly already in the cable duct pipe (12).
