Description

Bei der in, der letzten Zeit häufigen Verwendung von rohrförmigen Isolierstäben als Ausleger oder Stützstreben für Fahrleitungen an Stelle der sonst üblichen Stahlrohre hat sich gezeigt, daß diese meist als Porzellanrohre ausgebildeten Isolierstäbe leicht durch Schläge der Stromabnehmer oder sonstige äußere Einflüsse zerbrechen. Dies kann dann zu großen Betriebsstörungen führen, indem entweder der ganze Stützpunkt abfällt oder Teile des Rohres in-das Profil .des Stromabnehmers ragen.In the in, recent frequent use of tubular Insulating rods as cantilevers or support struts for contact lines instead of the otherwise Usual steel pipes have shown that they are usually designed as porcelain pipes Insulating rods easily due to blows from the pantograph or other external influences break. This can then lead to major operational disruptions, either by the whole support point falls off or parts of the pipe into the profile of the pantograph protrude.

Zur Vermeidung dieser Nachteile werden gemäß der Erfindung solche Isolierstäbe mit einer metallischen Einlage, vorzugsweise Stahl, versehen, so daß bei Bruch des keramischen Baustoffes der Isolierstab weiterhin zusammenhält.To avoid these disadvantages are according to the invention such Insulating rods with a metallic insert, preferably steel, provided so that If the ceramic building material breaks, the insulating rod continues to hold together.

Die Erfindung ist für der Zeichnung veranschaulicht, worin Fig. i einen im Erfindungssinne ausgeführten Isolierstab in: Seitenansicht und Fig. 2 und: 3 denselben im Querschnitt darstellen; Fig. q. zeigt eine bauliche Einzelheit.The invention is illustrated for the drawing, wherein Fig. I an insulating rod designed in the sense of the invention in: side view and Fig. 2 and: 3 represent the same in cross section; Fig. Q. shows a structural detail.

Es bezeichnen a einen rohrförmig ausgebildeten Isolierstab aus Porzellan od. dgl. und b eine metallische Einlage, vorzugsweise aus Stahl. Die Stahleinlage b ist entweder, wie aus Fig. 2 ersichtlich, zentrisch oder wegen etwa auftretender Biegungsbeanspruchungen zwischen den beiden Bauteilen gemäß Fig. 3 exzentrisch .in. dem Rohr geführt. Aus dem gleichen Grund ist wegen der verschiedenen Längendehnung der beiden Bauteile eine Feder c als elastisches Zwischenglied vorgesehen.It denotes a tubular insulating rod made of porcelain od. The like. And b a metallic insert, preferably made of steel. The steel insert b is either, as can be seen from Fig. 2, centric or because of some occurring Bending loads between the two components according to FIG. 3 eccentrically .in. out the pipe. The same reason is because of the different elongation in length of the two components, a spring c is provided as an elastic intermediate member.

Die Isolierstäbe können als Ersatz der Stahlrohre sowohl bei der Auslegeraufhängung als auch bei der seitlichen Festlegung dienen.The insulating rods can be used as a replacement for the steel pipes in both the boom suspension as well as for the lateral fixing.
