Description

Die vorliegende Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device according to the preamble of claim 1.

Zur Sicherung von Weichenzungen in Weichenstellsystemen werden Eisenbahnweichen mit Verschlussvorrichtungen ausgerüstet, wie sie z.B. in der DE 24 00 628 A1, oder in R. Hämmerli, Die Grundsätze der Sicherungsanlagen für den Eisenbahnbetrieb, herausgegeben von den Schweizerischen Bundesbahnen (SBB Kr I), Auflage vom Februar 1990, Band 1, Seiten 85 - 92 beschrieben sind. Auf Seiten 91 und 92 ist dort die Funktion einer modernen Verschlussvorrichtung (Klinkenverschluss CKA) beschrieben. Gezeigt ist ferner das Verriegeln bzw. Entriegeln sowie das Umstellen der Weichenzungen, das mittels einer Verschlussstange und einer Verschlussklinke geschieht. Die mit der Verschlussklinke über ein Verschlusslager verbundene Weichenzunge wird beim Verriegelungsvorgang von der Verschlussstange gegen die zugehörige Stockschiene geführt, wobei die Verschlussklinke unter der Stockschiene hindurch geführt und von der Verschlussstange zur Verriegelung der Weichenzunge nach oben gegen den Fuss der Stockschiene gepresst wird.To secure switch tongues in switch setting systems Railway switches equipped with locking devices, such as they e.g. in DE 24 00 628 A1, or in R. Hämmerli, the principles of the safety systems for railway operations by the Swiss Federal Railways (SBB Kr I), edition February 1990, Volume 1, pages 85-92. On Pages 91 and 92 is the function of a modern locking device (Latch lock CKA). Shown is also locking or unlocking and switching the switch tongues, which by means of a locking rod and a Lock latch happens. The one with the locking pawl over A lock bearing connected switch tongue is used during the locking process from the locking rod against the associated one Stick rail guided, the locking latch under the Stick rail passed through and from the locking rod to Lock the switch tongue up against the foot of the Stick rail is pressed.

Fig. 1 zeigt eine moderne Verschlussvorrichtung, die ein mit einer Weichenzunge 20 verbundenes Verschlusslager 40 aufweist, in dem in einer durchgehenden Öffnung 41 eine mittels einer Achse 4 drehbar gelagerte Verschlussklinke 1 vorgesehen ist, welche nach dem Verschliessen der Vorrichtung in eine Öffnung 31 eines Verschlussträgers 30 hinein ragt, der durch einen verschraubbaren Haken 5 mit einer Stockschiene 50 verbundenen ist. Die mit der Weichenzunge 20 verbundene Verschlussklinke 1 wird durch eine Verschlussstange 6, die durch die im Verschlussträger 30 und im Verschlusslager 40 vorgesehenen Öffnungen 31, 41 geführt ist, zwischen den Endpositionen bewegt und beim Verschliessen derart arretiert, dass das Kopfteil 11 der Verschlussklinke 1 nach oben gegen eine am Oberteil 33 des Verschlussträgers 30 vorgesehene Flanke 34 angedrückt wird. Fig. 1 shows a modern closure device, the one with a Turnout tongue 20 has connected lock bearing 40, in one in a continuous opening 41 by means of an axis 4 rotatably mounted locking pawl 1 is provided, which according to closing the device in an opening 31 of a closure carrier 30 protrudes through a screwable Hook 5 is connected to a stick rail 50. The one with the Switch tongue 20 connected latch 1 is by a Locking rod 6, which in the locking carrier 30 and in Closure bearing 40 provided openings 31, 41 is guided, moved between the end positions and when closing like this locked that the head part 11 of the locking pawl 1 upwards against one provided on the upper part 33 of the closure carrier 30 Edge 34 is pressed.

Die Unterseiten 32, 42 des Verschlussträgers 30 und des Verschlusslagers 40 sind vorzugsweise derart ausgestaltet, dass sie beim Verschliessen der Vorrichtung aneinander anstossen, wodurch vom Verschlussträger 30 eine Kraft auf das Verschlusslager 40 übertragen wird, durch die der Kopf 22 der Weichenzunge 20 an den Kopf 52 der Stockschiene 50 angepresst wird.The undersides 32, 42 of the closure carrier 30 and the closure bearing 40 are preferably designed such that they bump against each other when closing the device, whereby a force on the closure bearing 40 from the closure carrier 30 is transmitted through which the head 22 of the switch tongue 20 the head 52 of the stick rail 50 is pressed.

Zur Verbindung des Verschlusslagers 40 mit dem Fuss 21 der Weichenzunge 20 dient vorzugsweise eine Schraube 2, die durch eine im Weichenzungenfuss 21 vorgesehene Bohrung hindurch in das Kopfteil 43 des Verschlusslagers 40 eingedreht wird, welches eine zur Aufnahme des Weichenzungenfusses 21 vorgesehene Ausnehmung 44 aufweist, die gegebenenfalls mit vorzugsweise elastischen Füllelementen 3 aufgefüllt ist.For connecting the locking bearing 40 to the foot 21 of the switch tongue 20 is preferably a screw 2, which by a provided in the switch tongue foot 21 into the hole Head portion 43 of the lock bearing 40 is screwed in, which one recess provided for receiving the switch tongue foot 21 44, which optionally with preferably elastic Filling elements 3 is filled.

Aufgrund der mechanischen Belastungen der Verschlussvorrichtung über eine normalerweise sehr lange Einsatzzeit der Weiche besteht die Gefahr, dass sich die lösbaren Verbindungen wie beispielsweise die zur Verbindung von Weichenzunge 20 und Verschlusslager 40 vorgesehene Schraube 2 selbsttätig lösen kann. Auch andere der Verschlussvorrichtung zugeordnete Bauelemente können sich lösen oder ihre vorgesehene Position verlassen. So ist es möglich, dass die zur Lagerung der Verschlussklinke 1 vorgesehene, mit einem Exzenter gekoppelte Achse 4 oder in der Ausnehmung 44 vorgesehene Füllelemente 3 ihre Position verlassen, wodurch die Verschlussvorrichtung ihre Funktionen nicht mehr einwandfrei erfüllen kann. Durch diese Positionsänderung können Kräfte auftreten, die erhöhten Verschleiss und Lockerung von Befestigungselementen zur Folge haben.Due to the mechanical loads on the locking device over a normally very long operating time of the switch the risk that the detachable connections such as to connect the switch tongue 20 and lock bearing 40 provided screw 2 can loosen automatically. Other components associated with the closure device can loosen or leave their intended position.
