Description

Aufhängung für das Quertragwerk von Fahrleitungen elektrischer Bahnen. Um das Quertragwerk für Fahrleitungen elektrischer Bahnen stabiler und steifer gegen Kippen der senkrechten Stützen sowie gegen Windabtrieb zu machen, hat man bisher die doppelt ausgeführten und nebeneinanderliegenden Quertragdrähte bzw. Querspanndrähte entweder in der Mitte der Spannweite fischbauchartig auseinandergespreizt, oder man hat an den Masten besondere wagerechte Balken angeordnet, durch welche die Quertrag- und Querspanndrähte an ihren Enden auseinandergespreizt wurden, während sie in der Mitte der Spannweite gegeneinander zusammengezogen waren.Suspension for the transverse support structure of overhead lines for electric railways. In order to make the transverse support structure for contact lines of electric railways more stable and stiffer against Tilting the vertical supports as well as against wind downforce has been done so far the cross-supporting wires or cross-tensioning wires, which are executed twice and lying next to one another either spread apart like a fish belly in the middle of the wingspan, or special horizontal beams have been arranged on the masts through which the Cross support and tension wires were spread apart at their ends while they were in the Were contracted against each other in the middle of the span.

Gemäß der Erfindung werden diese beiden Anordnungen kombiniert, indem die Quertrag-und Querspanndrähte in der Mitte der Spannweite fischbauchartig auseinandergespreizt sind, sich aber im weiteren Verlauf treffen oder kreuzen und dann an den Enden der Balken auseinanderlaufend abgespannt werden. An den Kreuzungspunkten sind die Quertrag- oder Spanndrähte miteinander fest verbunden, so daß das ganze Quertragwerk in drei je für sich starre Systeme geteilt wird. Hieraus ergeben sich neue besondere Vorteile.According to the invention, these two arrangements are combined by the transverse support and transverse tensioning wires spread apart like a fish belly in the middle of the span are, but in the further course meet or cross and then at the ends of the Beams diverging to be tensioned. At the crossing points are the transverse support or tension wires firmly connected to each other, so that the whole transverse structure in three each rigid system is shared. This results in new special advantages.

Die Zeichnung stellt ein Ausführungsbeispiel für die Erfindung dar. Die Fahrdrähte n sowie die Längstragdrähte o sind an dem Quertragsystem a-k aufgehängt, dessen Quertragdrähte a sowohl als auch die Querspanndrähte b mit ihren Enden an den Balken c befestigt sind. Unter der Annahme, daß die Balken und die Masten m genügend steif ausgeführt sind, sind die Kreuzungs-oder Berührpunkte d selbst als starr im Raum anzusehen, da sie durch die beiden Enden der Querdrähte a bzw. b dreieckförmig am Mast verankert sind. Das mittlere, zwischen den beiden Knotenpunkten d liegende System wird daher wesentlich kürzer und damit stabiler. Dies ist ein bedeutender Vorteil der neuen Anordnung. Ein weiterer Vorteil ist der, daß beim Bruch eines Drahtes - sei es im mittleren Feld zwischen den Knotenpunkten, sei es in den äußeren Feldern zwischen den Knotenpunkten und den Masten - die Durchhangsvergrößerung eine wesentlich geringere ist und die bei einem derartigen Bruch und einer derartigen Durchhangsvergrößerung auftretenden dynamischen Wirkungen ebenfalls geringer und günstiger ausfallen.The drawing shows an exemplary embodiment of the invention. The contact wires n and the longitudinal support wires o are suspended from the transverse support system ak, the transverse support wires a of which as well as the transverse tensioning wires b are attached at their ends to the beams c. Assuming that the beams and the masts m are made sufficiently rigid, the intersection or contact points d themselves are to be regarded as rigid in space, since they are anchored triangularly on the mast by the two ends of the transverse wires a and b. The middle system lying between the two nodes d is therefore much shorter and therefore more stable. This is a major advantage of the new arrangement. Another advantage is that when a wire breaks - be it in the middle field between the nodes, be it in the outer fields between the nodes and the masts - the increase in sag is significantly lower and that in the case of such a break and such increase in sag occurring dynamic effects also turn out to be lower and cheaper.

Konstruktiv ist es von Vorteil, daß die mittlere Länge der Spreizen f wesentlich geringer ist und damit auch die weiteren Konstruktionsteile, wie die Stützen g, die an diesen befestigten Querarme h, die Hängedrähte i, die seitlichen Festlegungen k, sehr einfach gestaltet sind.Constructively, it is advantageous that the middle length of the spreaders f is much lower and thus also the other structural parts, such as the Supports g, the attached cross arms h, the hanging wires i, the lateral Stipulations k, are very simple.
