Description
Bei Schienenfahrzeugen mit elektrischem Antrieb bilden die Schienen den Rückleiter. Diese Schienen wurden bisher geschweißt oder wie üblich mit Laschen verbunden und mit einem aus Kupferseil und Anschweißenden versehenen Schienenverbinder ausgerüstet. Bei Grubenschienen waren die geschweißten Schienen durch Gebirgsdruck gefährdet. Auch bei den Ausführungen mit losen Beilagen in irgendeiner Form als Leiter stellten sich Mißstände heraus. Die Beilagen wurden nicht ordnungsmäßig eingebaut, gingen verloren oder wurden gestohlen.In rail vehicles with an electric drive, the rails form the return conductor. These rails were previously welded or, as usual, with tabs connected and provided with a rail connector made of copper cable and welding ends equipped. In the case of pit rails, the welded rails were due to rock pressure endangered. Even with the versions with loose enclosures in any form as Ladders turned out to be grievances. The enclosures were not installed properly, were lost or stolen.
Durch die Erfindung sollen diese gefährlichen und kostspieligen Arbeiten unter Tage bei Stromlaschen an Rückleiterschienen vermieden und die Schienenstöße in einfacher, gebräuchlicher Weise verbunden werden. Die Erfindung bezieht sich auf eine elektrisch leitende Schienenstoßverbindung, bei der die Stromüberleitung durch zwischen Schienen und Laschen angeordnete Zwischenlagen aus elektrisch gut leitendem Baustoff, z. B. Kupfer, erfolgt.The invention aims to do this dangerous and costly work underground with power lugs on return rails avoided and the rail joints can be connected in a simple, commonly used manner. The invention relates to on an electrically conductive rail joint connection, in which the current transfer through intermediate layers arranged between rails and brackets from electrically good conductive building material, e.g. B. copper takes place.
Die Erfindung besteht darin, daß an den Angriffsflächen der Laschen Leiterstäbe in an den Laschen vorgesehenen Nuten eingewalzt sind. Durch scharfes Anziehen der Laschenschrauben werden diese Leiterstäbe so an die Schienen angepreßt, daß die Rückleitung gewährleistet ist, zumal die Rückleiter der Laschen einen Querschnitt erhalten, daß sie zusammen das i,5fache des Fahrdrahtquerschnittes ausmachen. Die Zeichnung stellt ein Ausführungsbeispiel dar. Fig. I zeigt einen Schienenkopf mit zwei Laschen im Schnitt; Fig. II zeigt einen Schienenstoß in der Ansicht. Die Schiene i wird mit den Laschen .2 durch die Laschenschrauben 5 verbunden. Die Laschen erhalten beiderseits Nuten 3, in die Rundkupferstäbe 4 eingewalzt sind. Diese stehen so weit vor, daß sie beim Anpressen an die Schiene i durch die Laschenschrauben 5 in ihrer ganzen Länge zum Tragen kommen und somit die gewünschte Leitfähigkeit hergestellt wird. Diese erfolgt durch vier Laschen mit je zwei Leitern.The invention consists in that on the contact surfaces of the tabs Conductor bars are rolled into grooves provided on the tabs. By sharp When the bracket screws are tightened, these ladder bars are pressed against the rails in such a way that that the return line is guaranteed, especially since the return line of the tabs has a cross section get that they together make up 1.5 times the contact wire cross-section. the Drawing shows an embodiment. Fig. I shows a rail head with two tabs in the cut; Fig. II shows a rail joint in the view. The rail i is connected to the tabs .2 by the tab screws 5. Got the tabs Grooves 3 on both sides into which round copper rods 4 are rolled. These are so far before that they when pressed against the rail i by the tab screws 5 in their entire length come into play and thus the desired conductivity is established will. This is done by four brackets with two conductors each.
