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 patent claim 1.

Zur Sicherung von Weichenzungen werden Eisenbahnweichen mit Verschlussvorrichtungen ausgerüstet, wie sie z.B. 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 (bezüglich weiteren Informationen zur Weichentechnik siehe a.a.O., Seiten 66 - 80). Auf Seiten 91 und 92 ist die Funktion einer modernen Verschlussvorrichtung (Klinkenverschluss CKA) beschrieben. Gezeigt ist 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, railway switches are equipped with locking devices, such as published in R. Hämmerli, The principles of safety systems for railway operations by the Swiss Federal Railways (SBB Kr I), edition from February 1990, volume 1, pages 85 - 92 are described (for further information on turnout technology see above, pages 66-80). On pages 91 and 92 is the function of a modern locking device (latch lock CKA). Shown is locking or unlocking as well as switching the switch tongues, that happens by means of a locking rod and a locking pawl. The one with the latch Turnout tongue connected via a lock bearing is removed from the lock rod during the locking process led against the associated stick rail, the locking pawl under the stick rail passed through and up from the locking bar to lock the switch tongue is pressed against the foot of the stick rail.

Insbesondere bei Weichenzungen mit grösseren Längen, wie sie bei grösseren Kurvenradien notwendig sind, treten beim Befahren unerwünschte Schwingungen auf. Diese Weichenzungen sind zudem vermehrt torsionsgefährdet, wodurch ein Abheben der Weichenzunge von der Stockschiene auftreten kann. Aus der EP 0 624 508 A1 ist eine Verschlussvorrichtung bekannt, bei der eine formschlüssige Verbindung der Weichenzunge mit der Stockschiene angestrebt wird. Dies wird erreicht, indem das mit der Weichenzunge verbundene Verschlusslager mit einer Verlängerung versehen wird, die beim Verriegeln der Verschlussvorrichtung gegen einen starr mit der Stockschiene verbundenen Verschlussträger andrückt, wodurch die Weichenzunge um das Verschlusslager gedreht und formschlüssig gegen die Stockschiene gedrückt wird. Im Aufgabe "weichen stellsystem in tastenschwelle" von werner Hänni C sinal + Draht, Ausgabe 86 (1994), Seiten 294-297) wird ebenfalls eine Verschlußvorrichtung gemäß Oberbegriff des Anspruches 1 offen bart.Especially with switch blades with longer lengths, as is necessary with larger curve radii undesirable vibrations occur when driving on. These switch tongues have also increased At risk of torsion, which can result in the switch tongue lifting off the stick rail. A closure device is known from EP 0 624 508 A1, in which a positive connection the switch tongue is aimed at with the stick rail. This is achieved by using the Turnout tongue connected lock bearing is provided with an extension that when locking the locking device presses against a locking carrier rigidly connected to the pole rail, whereby the switch tongue is rotated around the lock bearing and positively against the pole rail is pressed. In the task "soft actuation system at key threshold" by werner Hänni C sinal + Draht, Edition 86 (1994), pages 294-297) also becomes a closure device beard open according to the preamble of claim 1.

Bei den Weichen werden die Stockschienen und die Weichenzungen insbesondere bei hohen Fahrgeschwindigkeiten durch den Achsdruck, durch horizontal wirkende Kräfte sowie Vibrationen stark belastet. Die spanabhebende Bearbeitung bei der Herstellung der Weichenzungen zerstört ferner die Walzstruktur der Schienenprofile, so dass durch die Walkeinwirkung beim Befahren durch die Fahrzeugräder und die Vibration der Fahrzeugräder leicht eine Verwerfung und ein Verzug insbesondere im Bereich der Spitze der Weichenzunge auftreten kann.In the turnouts, the stick rails and the switch tongues are used especially at high speeds heavily stressed by the axle pressure, horizontal forces and vibrations. The machining in the manufacture of the switch tongues also destroys the rolling structure of the rail profiles, so that the impact of walking when driving through the vehicle wheels and the Vibration of the vehicle wheels easily causes warping and warping especially in the area of the tip the switch tongue can appear.

Insbesondere bei stark belasteten Weichen wäre es daher von Vorteil, wenn die Verschlussvorrichtungen eine zusätzlich erhöhte Sicherheit in bezug auf die Unterdrückung von Schwingungen sowie Verwerfungen der Weichenzungen und das horizontale und/oder vertikale Abheben derselben aufweisen würden. Ferner ist die Vermeidung des Aufschneidens oder Auffahrens der Weiche von erheblicher Bedeutung. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Verschlussvorrichtungen dahingehend zu verbessern. It would therefore be of advantage if the locking devices were used, particularly in the case of heavily loaded switches an additional increased security with regard to the suppression of vibrations and faults which would have switch tongues and the horizontal and / or vertical lifting thereof. Avoiding cutting or opening the switch is also of great importance. The object of the present invention is to close these closure devices improve.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Massnahmen gelöst. Vorteilhafte Ausgestattungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved by the measures specified in the characterizing part of patent claim 1 solved. Advantageous configurations of the invention are specified in further claims.

Die erfindungsgemässe Verschlussvorrichtung ist stabil mit der Stockschiene und der Weichenzunge verbindbar und bedarfsweise justierbar, so dass ein Aufklaffen bzw. eine Verwerfung der verschlossenen Weichenzunge verhindert wird. Ein Aufschneiden der Weiche von der Spitze her durch den Spurkranz eines Eisenbahnrades wird dadurch ausgeschlossen. Ferner weist die Weichenzunge, die aus einer konventionellen Stockschiene gefertigt werden kann, eine verbesserte Stabilität auf. Die Stockschiene und die vorzugsweise aus einer Stockschiene gefertigte Weichenzunge weisen annähernd dieselbe Grösse auf, wodurch die Entfernung von gegeneinander gerichteten Teilen des Schienenfusses (Fig. 1, Ziff. 21; 51) bei Stockschiene und Weichenzunge erforderlich ist. Die dadurch entstehende Reduktion der Auflagefläche des Schienenfusses wird durch die erfindungsgemäss vorgesehenen Massnahmen kompensiert.The closure device according to the invention is stable with the stick rail and the switch tongue connectable and adjustable if necessary, so that a gaping or rejection of the closed Turnout tongue is prevented. Cutting the switch from the top through the wheel flange a railway wheel is excluded. Furthermore, the switch tongue, which consists of a conventional Stick rail can be made, improved stability. The stick rail and the switch tongue, which is preferably made from a stick rail, has approximately the same size on, whereby the removal of mutually directed parts of the rail foot (Fig. 1, point 21; 51) is required for the stick rail and switch tongue. The resulting reduction in the contact area the rail foot is compensated for by the measures provided according to the invention.

Fig. 8 zeigt die aus der EP 0 624 508 A1 bekannte Verschlussvorrichtung, die eine über eine Achse 012 sowie ein Verschlusslager 040 mit einer Weichenzunge 020 verbundene Verschlussklinke 01 aufweist. welche nach dem Verschliessen in eine Öffnung 034 eines mit einer Stockschiene 050 verbundenen Verschlussträgers 030 hinein ragt und darin durch eine Verschlussstange 06 arretiert ist. Das Verschlusslager 040 ist unten mit einer Verlängerung 07 versehen, die bei verschlossener Verschlussvorrichtung an den Verschlussträger 030 anstösst, welcher eine Kraft F1 auf das Verschlusslager 040 überträgt, durch die der Kopf 022 der Weichenzunge 020 an den Kopf 052 der Stockschiene 050 angepresst wird.8 shows the closure device known from EP 0 624 508 A1, which has an axis 012 and a locking bearing 040 with locking pawl 01 connected to a switch tongue 020. which after being closed in an opening 034 connected to a stick rail 050 Lock carrier 030 protrudes into it and is locked therein by a lock rod 06. The lock bearing 040 is provided with an extension 07 at the bottom, which is attached when the locking device is closed pushes the closure carrier 030, which transmits a force F1 to the closure bearing 040 the head 022 of the switch tongue 020 is pressed onto the head 052 of the pole rail 050.

Das Verschlusslager 040 ist durch eine Schraube 08 mit dem Fuss 021 der Weichenzunge 020 verbunden, die derart ausgestaltet ist, dass deren Fuss 021, beim Anliegen des Kopfs 022 der Weichenzunge 020 an den Kopf 052 der Stockschiene 050, über dem Fuss 051 der Stockschiene 050 liegt (siehe z.B. auch Fig. 3 der EP 0 455 182 A2). Da die Weichenzunge 020 durch die Schraube 08 lediglich am Schienenfuss 021 gehalten wird, ist trotz der Krafteinwirkung über die Verlängerung 07 eine relativ hohe Schwingungsneigung der Weichenzunge 020 vorhanden. Der Verschlussträger 030, der nur mit dem Fuss 051 der Stockschiene 050 verbunden ist, verfügt zudem nicht über die gewünschte Stabilität. Zu beachten ist ferner, dass die Fertigung der Weichenzunge 020, die unabhängig von der Stockschiene 050 in einem vollkommen getrennten Produktionsvorgang erfolgt, mit einem verhältnismässig grossen Aufwand verbunden ist.The locking bearing 040 is connected to the foot 021 of the switch tongue 020 by a screw 08, which is designed in such a way that its foot 021 when the head 022 of the switch tongue rests 020 to the head 052 of the pole rail 050, over which foot 051 of the pole rail 050 lies (see e.g. also Fig. 3 of EP 0 455 182 A2). Since the turnout tongue 020 only on the rail foot through screw 08 021 is held, is a relatively high despite the force exerted by the extension 07 There is a tendency for the switch tongue 020 to vibrate. The closure carrier 030, which only with the Foot 051 of the pole rail 050 is also not stable. To Note also that the manufacture of the switch tongue 020, which is independent of the stick rail 050 takes place in a completely separate production process, with a relatively large one Effort is connected.

Die in Fig. 1 in einer Schnittdarstellung gezeigte erfindungsgemässe Verschlussvorrichtung weist, wie die bekannte Vorrichtung (siehe Fig. 8), eine über eine Achse 12 sowie ein Verschlusslager 40 mit einer Weichenzunge 20 verbundene Verschlussklinke 1 auf, welche in verschlossenem Zustand (siehe Fig. 2) in eine Öffnung 34 eines mit einer Stockschiene 50 verbundenen Verschlussträgers 30 hinein ragt und darin durch eine Verschlussstange 6 arretiert ist, die auf einer die Öffnung 34 begrenzenden Auflagefläche 35 gelagert ist. Die Weichenzunge 20, die aus einem Kopfstück 22, einem Steg 23 und einem Fussstück 21 besteht, unterscheidet sich von einer Stockschiene 50, die ebenfalls ein Kopfstück 52, einen Steg 53 und ein Fussstück 51 aufweist, durch die Ausgestaltung des Kopfstücks 22 bzw. 52. Die erfindungsgemässe Vorrichtung erlaubt daher die Verwendung einer Stockschiene 50 zur Herstellung einer Weichenzunge 20, die durch Bearbeitung von Schienenkopf 52; 22 und Schienenfuss 51; 21 kostengünstig erfolgen kann. Der Schienenfuss 51 der Stockschiene 50 und der Schienenfuss 21 der Weichenzunge 20 liegen dabei zumindest annähernd auf derselben Höhe und sind derart angeschnitten, dass die Weichenzunge 20 gegen die Stockschiene 50 führbar ist, bis das Kopfstück 52 der Stockschiene 50 und das Kopfstück 22 der Weichenzunge 20 aufeinander treffen.The closure device according to the invention shown in a sectional illustration in FIG. 1 shows how the known device (see Fig. 8), one via an axis 12 and a lock bearing 40 with a Turnout tongue 20 connected locking pawl 1, which in the closed state (see Fig. 2) protrudes into an opening 34 of a closure carrier 30 connected to a stick rail 50 and is locked therein by a locking rod 6, which rests on a contact surface delimiting the opening 34 35 is stored. The switch tongue 20, which consists of a head piece 22, a web 23 and a Foot piece 21 is different from a stick rail 50, which is also a head piece 52, has a web 53 and a foot piece 51, through the design of the head piece 22 and 52, respectively The device according to the invention therefore allows the use of a stick rail 50 for production a switch tongue 20, which is machined by rail head 52; 22 and rail foot 51; 21 inexpensive can be done. The rail foot 51 of the stick rail 50 and the rail foot 21 of the switch tongue 20 are at least approximately at the same height and are cut in such a way that the switch tongue 20 can be guided against the stick rail 50 until the head piece 52 of the stick rail 50 and the head piece 22 of the switch tongue 20 meet.

Das Verschlusslager 40, das mit Auflageflächen 42 versehen ist, auf der der Fuss 21 der Weichenzunge 20 mit wenigstens einer Schraube 8a, 8b befestigt ist, weist seitlich zur Weichenzunge 20 ein Kopfelement 41 auf, durch das eine vorzugsweise mit einem Schaft und einem Zylinder versehene Stellschraube 11 gegen den Steg 23 der Weichenzunge 20 geschraubt ist. Durch die Stellschraube 11, die aus einem mit einem Gewinde versehenen Schaft und einem Zylinder besteht, wird ein Druck ausgeübt, der verhindert, dass Schwingungen oder Verwerfungen der Weichenzunge 20 bzw. Bewegungen der Weichenzunge 20 relativ zur Verschlussvorrichtung entstehen. Aus Fig. 7 ist ferner ersichtlich, dass zur Befestigung der Schrauben 8a je eine Hülsen 80 vorgesehen ist, die in die entsprechende Gewindebohrung eingesenkt wird und durch die der vom Schienenfuss 21 ausgeübte Druck gleichmässig auf die Auflagefläche des Schraubenkopfes verteilt wird.The locking bearing 40, which is provided with contact surfaces 42, on which the foot 21 of the switch tongue 20 is fastened with at least one screw 8a, 8b, has a head element laterally to the switch tongue 20 41, through which an adjusting screw, preferably provided with a shaft and a cylinder 11 is screwed against the web 23 of the switch tongue 20. By adjusting screw 11, the consists of a threaded shaft and a cylinder, pressure is applied, which prevents vibrations or warping of the switch tongue 20 or movements of the Switch tongue 20 arise relative to the closure device. From Fig. 7 it can also be seen that for Attachment of the screws 8a, a sleeve 80 is provided, which in the corresponding threaded hole is sunk in and through which the pressure exerted by the rail foot 21 evenly on the support surface the screw head is distributed.

Das Verschlusslager 40 weist ferner ein Fusselement 43 auf, das in verschlossener Stellung der Verschlussvorrichtung, z.B. wie in Fig. 8 gezeigt, gegen das Fusselement 33 des Verschlussträgers 30 andrückt. Vorzugsweise ist im Fusselement 43 des Verschlusslagers 40 jedoch wenigstens einen Justierbolzen 7a (aus Fig. 7 ist ersichtlich, dass vorzugsweise zwei Justierbolzen 7a, 7b verwendet werden) vorgesehen, der derart einstellbar ist, dass er bei verschlossener Stellung der Verschlussvorrichtung gegen das Fusselement 33 des Verschlussträgers 30 andrückt, wodurch eine Kraft F1 übertragen wird. Dadurch wird verhindert, dass Bewegungen der Weichenzunge 20 und des Verschlusslagers 20 relativ zum Verschlussträger 30 entstehen. Der Kopf 22 der Weichenzunge 20 wird bei verschlossener Vorrichtung daher stabil an den Kopf 52 der Stockschiene 50 angepresst.The locking bearing 40 also has a foot element 43 which, in the closed position of the locking device, e.g. as shown in FIG. 8, presses against the foot element 33 of the closure carrier 30. However, there is preferably at least one adjustment bolt in the base element 43 of the lock bearing 40 7a (from FIG. 7 it can be seen that preferably two adjusting bolts 7a, 7b are used) provided that is adjustable such that it is in the closed position of the closure device presses against the foot element 33 of the closure carrier 30, whereby a force F1 is transmitted. This prevents movements of the switch tongue 20 and the lock bearing 20 relative to the closure carrier 30 arise. The head 22 of the switch tongue 20 is when the device is closed therefore firmly pressed onto the head 52 of the stick rail 50.

Die Justierbolzen 7a, 7b bestehen vorzugsweise aus einem mit einem Gewinde versehenen Schaft, der koaxial mit einem Zylinder verbunden ist. Der Zylinder weist vorzugsweise ein konisch verlaufendes Ende auf, das beim Verschliessvorgang gegen eine geneigte Fläche des Fusselementes 33 des Verschlussträgers 30 geführt wird. Dadurch wird verhindert, dass beim Verschliessvorgang Schottersteine zwischen den Justierbolzen 7a, 7b und dem Verschlussträger 30 eingeklemmt werden. Bei der in der EP 0 624 508 A1 gezeigten Vorrichtung trifft die Verlängerung des Verschlusslagers hingegen frontal auf den Fuss des Verschlussträgers.The adjusting bolts 7a, 7b preferably consist of a threaded shaft which is coaxially connected to a cylinder. The cylinder preferably has a conical shape End on that during the closing process against an inclined surface of the foot member 33 of the closure carrier 30 is performed. This prevents ballast stones from being closed are clamped between the adjusting bolts 7a, 7b and the closure carrier 30. At the in the EP 0 624 508 A1 shown, however, the extension of the locking bearing hits the front the foot of the fastener carrier.

Das Verschlusslager 40 ist in Fig. 6 von der Seite und in Fig. 7 von der der Weichenzunge 20 abgewandten Seite gezeigt. Die Sicherungsplatte 48 ist in Fig. 6 im Schnitt dargestellt (Fig. 7, Schnittlinie SS). In Fig. 7 sind die Köpfe der gegen den Fuss 33 des Verschlussträgers 31 bzw. gegen den Steg 23 der Weichenzunge 20 gedrehten Justierbolzen 7a, 7b und Stellschraube 11 gezeigt. Nach der Justierung werden die Justierbolzen 7a, 7b und die Stellschraube 11 durch eine mit Öffnungen 70a, 110 für die Schraubenköpfe versehenen Platte 48, die mittels Schrauben 17 befestigt wird, gesichert.The locking bearing 40 is in FIG. 6 from the side and in FIG. 7 from that facing away from the switch tongue 20 Page shown. The securing plate 48 is shown in section in FIG. 6 (FIG. 7, section line SS). 7, the heads are against the foot 33 of the closure carrier 31 or against the web 23 the turnout tongue 20 rotated adjustment bolts 7a, 7b and adjusting screw 11 shown. After adjustment the adjusting bolts 7a, 7b and the adjusting screw 11 through one with openings 70a, 110 for the Plate 48 provided with screw heads, which is fastened by means of screws 17.

Durch die im Verschlusslager 40 vorgesehene Öffnung 44 sind die Verschlussklinke 1, die durch eine Exzentervorrichtung 18 justierbare Achse 12 sowie die im Schnitt gezeigte Verschlussstange 6 sichtbar. Anhand der Exzentervorrichtung 18 kann die Verschlussklinke 1 vor und zurück verschoben werden, wodurch die zur Verriegelung vorgesehene Flanke 15 (siehe Fig. 1) der Verschlussklinke 1 auf die dazu korrespondierende Flanke 36 des Verschlussträgers 31 abgestimmt werden kann.Through the opening 44 provided in the locking bearing 40, the locking pawl 1, which by a Eccentric device 18 adjustable axis 12 and the locking rod 6 shown in section visible.

Der Verschlussträger 30, der in Fig. 3 von der Seite und in Fig. 4 von der der Stockschiene 50 abgewandten Seite gezeigt ist, weist ein Kopfelement 31 und Fusselement 33 auf. Die zur Durchführung der Verschlussklinke 1 vorgesehene Öffnung 34 des Verschlussträgers 30 wird durch das U-förmig ausgestaltete Fusselement 33 umrahmt (siehe Fig. 4), das auf der Oberseite Auflageflächen 32 für den Fuss 51 der Stockschiene 50 aufweist. Der Schienenfuss 51 wird z.B. mit dem Fusselement 33 verschraubt. Vorzugsweise werden jedoch die in Fig. 3 gezeigten Massnahmen zum Befestigen des Schienenfusses 51 auf den Auflageflächen 32 angewendet. Dazu ist wenigstens ein Zylinder 14a vorgesehen, der durch eine durch das Kopfelement 31 geführte Schraube 13a zwischen eine geneigte Flanke 37 des Kopfelementes 31 und den Schienenfuss 51 gezogen wird, wodurch der Schienenfuss 51 nach unten gegen die Auflagefläche 32 gepresst wird. Dadurch wird die Verwendung einer Befestigungsschraube bzw. die mit einem verhältnismässig grossen Aufwand verbundene Bohrung eines Loches durch den Fuss 51 der Stockschiene 50 und das Schneiden eines Gewindes vermieden. Aus Fig. 4 ist ersichtlich, dass Zylinder 14a und 14b sowie zugehörige Schrauben 13a und 13b auf beiden Seiten des Verschlussträgers 30 vorgesehen sind. Die Auflagefläche 32 kann durch entsprechende Neigung an Schienenanlagen angepasst werden, welche nach innen oder nach aussen geneigte Schienenprofile verwenden.
