Abstract

A rail switch control mechanism including a locking clamp which is shiftable using a path rod. The locking clamp has, on an end facing the switch tonque, a swivel head. The swivel head is swivelably connected with a switch tongue. In use, the locking clamp cooperates with a locking piece. In the locked position of the clamp, a shoulder of the locking clamp contacts a shoulder of the locking piece. The switch tongue rail is linked to the swivel head with the interposition of a pin arranged with an elongated slot extending longitudinally of the tongue rail. The elongated slot is arranged within a connecting member which is rigidly connected to the switch tongue rail, e.g. by being threadedly connected, to the web of the switch tongue rail.

Description

Die Erfindung bezieht sich auf eine Weichenbetätigungsvor­richtung mit einer durch eine Schieberstange verschiebbaren Verschlußklammer, deren der Weichenzunge od.dgl. zugewendetes Ende einen Gelenkkopf aufweist, mit welchem die Weichenzunge drehgelenkig verbunden ist, und deren anderes Ende einen Ver­schlußklammerkopf aufweist, welcher mit einem Verschlußstück zusammenwirkt, wobei eine Schulter des Verschlußklammerkopfes in Verschlußstellung an einer Schulter des Verschlußstückes anliegt und wobei die Weichenzungenschiene am Gelenkkopf der Verschlußklammer über einen in einem sich in Längsrichtung der Zungenschiene erstreckenden Langloch angeordneten Zapfen angelenkt ist. Insbesondere bei extremen Temperaturverhält­nissen tritt eine Längendehnung der Weichenzunge auf, welche, wenn die Weichenzunge starr am Gelenkkopf angelenkt ist, zu einem Verklemmen der Schieberstange und der Verschlußkammer im Verschlußstück führen kann. Dadurch, daß der Zapfen, über welchen die Weichenzunge an den Gelenkkopf angelenkt ist, in ein sich in Längsrichtung der Weichenzunge erstreckendes Langloch an der Weichenzunge eingreift, werden solche Längs­dehnungen der Weichenzunge aufgenommen und unschädlich gemacht. Eine solche Anordnung ist aus der AT-PS 250 433 bekannt geworden. Hier greift der Zapfen in ein Langloch im Schienefuß der Zungenschiene ein. Dies hat aber den Nach­teil, daß die Zungenschiene durch dieses Langloch geschwächt wird, wodruch eine Bruchgefahr entsteht. Aus der AT-PS 382 128 ist eine Anordnung bekannt geworden, bei welcher das Verschlußstück mit der Backenschiene in Schienen­längsrichtung verschieblich verbunden ist, um Längendehnungen der Zungenschiene aufzunehmen. Bei dieser Anordnung ist der Gelenkkopf der Verschlußklammer starr an den Zungenschiene angelenkt, so daß eine Schwächung der Zungenschiene durch im Schienefuß angeordnete Länglocher vermieden wird. Die Lagerung des Zapfens für die Anlenkung des Gelenkkopfes ist mit dem Verschlußstück über ein Gestänge verbunden und durch die Längendehnung der Weichenzunge wird daher das Verschluß­stück an der Backenschiene verschoben, so daß die Relativlage des Verschlußstückes zum Anlenkpunkt der Zungenschiene an den Gelenkkopf unverändert bleibt. Hier müssen Gleitflächen für das Verschlußstück vorgesehen sein und wenn diese Gleit­flächen nicht dauernd gewartet werden, so ist ein Verreiben dieser Gleitflächen möglich und es können wieder Verklemmungen eintreten. Eine solche Ausbildung ist verhält­nismäßig kompliziert und aufwendiung und bietet auch keine volle Sicherheit gegen Verklemmungen, da ja das Verschluß­stück bei Längendehnungen der Zungenschiene mitgenommen werden muß und schon bei der Mitnahme durch das Gestänge Verklemmungen eintreten können. Bei der Ausführungsform hingegen, bei welcher die Anlenkung der Zungenschiene an den Gelenkkopf der Verschlußklammer über ein Langloch erfolgt, werden Längendehnungen der Zungenschiene unmittelbar dort ausgeglichen, wo sie entstehen.The invention relates to a switch actuating device with a sliding clamp which can be displaced by a push rod, the switch tongue or the like of which. facing end has a joint head, with which the switch tongue is pivotally connected, and the other end has a locking clip head, which cooperates with a locking piece, wherein a shoulder of the locking clip head rests in the closed position on a shoulder of the locking piece and wherein the switch tongue rail on the joint head of the locking clip over a pin arranged in an elongated hole extending in the longitudinal direction of the tongue rail is articulated. Particularly in extreme temperature conditions, there is a longitudinal expansion of the switch tongue, which, if the switch tongue is rigidly articulated to the joint head, can lead to jamming of the slide rod and the locking chamber in the locking piece. Characterized in that the pin, via which the switch tongue is articulated on the joint head, engages in an elongated hole on the switch tongue extending in the longitudinal direction of the switch tongue, such longitudinal stretches of the switch tongue are absorbed and rendered harmless. Such an arrangement has become known from AT-PS 250 433. Here the pin engages in an elongated hole in the rail foot of the tongue rail. However, this has the disadvantage that the tongue rail is weakened by this elongated hole, which creates a risk of breakage. An arrangement has become known from AT-PS 382 128, in which the closure piece is connected to the stock rail so as to be displaceable in the longitudinal direction of the rail in order to accommodate longitudinal expansion of the tongue rail. In this arrangement, the joint head of the locking clip is rigidly articulated on the tongue rail, so that weakening of the tongue rail by elongated holes arranged in the rail foot is avoided. The bearing of the pin for the articulation of the joint head is connected to the closure piece via a linkage and through the lengthening of the switch tongue is therefore shifted the closure piece on the stock rail, so that the relative position of the closure piece to the point of articulation of the tongue rail on the joint head remains unchanged. Here, sliding surfaces must be provided for the closure piece and if these sliding surfaces are not continuously maintained, rubbing these sliding surfaces is possible and jamming can occur again. Such training is relatively complicated and expensive and does not offer full security against jamming, since the closure piece must be taken along when the tongue rail is elongated and jamming can occur even when it is taken along by the linkage. In contrast, in the embodiment in which the tongue rail is articulated to the joint head of the locking clip via an elongated hole, longitudinal expansions of the tongue rail are compensated for directly where they arise.

Aufgabe der Erfindung ist es, bei einer oben beschriebenen Anordnung die Konstruktion zu vereinfachen, eine Bruchgefahr der Zungenschiene auszuschalten und eine präzisere Anlenkung und Führung der Verschlußklammer zu ermöglichen. Zur Er­füllung dieser Aufgabe besteht die Erfindung im wesentlichen darin, daß das Langloch in einem mit der Weichenzungenschiene od.dgl. starr verbunden, insbesondere verschraubten, Anschlußstück angeordnet ist. Dadurch, daß das Langloch in einem Anschlußstück vorgesehen ist, wird eine Schwächung des Schienenfußes der Weichenzungenschiene od.dgl. vermieden. Wenn dieses Anschlußstück mit der Weichenzungenschiene verschraubt ist, so stellen die Schraublöcher keine gefähr­liche Schwächung dar. Dadurch, daß eine Schwächung der Schiene durch ein Langloch vermieden wird, kann diese Weichenbetätigungsvorrichtung sowohl als erster Verschluß für die Schienenzunge, als auch als zweiter oder dritter Ver­schluß, beispielsweise für die Flügelschienen, Anwendung finden. Ein solches Anschlußstück kann präziser bearbeitet sein als der Schienenfuß und es kann daher die Anlenkung des Anschlußstückes an den Gelenkkopf präziser erfolgen. Zweckmäßig weist das Anschlußstück eine planparallele Platte auf, in welcher das Langloch angeordnet ist, wobei vorzugsweise der Gelenkkopf die Platte beidseitig umgreift. Eine solche planparallele Platte kann so präzise bearbeitet sein, daß bei geringem Spiel zwischen den Anlageflächen von Gelenkkopf und Platte eine leichte Gängigkeit gewährleistet ist.The object of the invention is to simplify the construction in an arrangement described above, to eliminate the risk of breakage of the tongue rail and to enable a more precise articulation and guidance of the locking clip. To achieve this object, the invention consists essentially in that the elongated hole or the like in a with the switch tongue rail. rigidly connected, in particular screwed, connector is arranged. Characterized in that the elongated hole is provided in a connector, a weakening of the rail foot of the switch tongue rail or the like is. avoided. If this connecting piece is screwed to the switch tongue rail, the screw holes do not represent a dangerous weakening. By avoiding the rail being weakened by an elongated hole, this switch actuating device can be used both as a first closure for the rail tongue and as a second or third closure. for example for the wing rails. Such a connector can be machined more precisely be than the rail foot and therefore the articulation of the connector to the joint head can be done more precisely. The connecting piece expediently has a plane-parallel plate in which the elongated hole is arranged, the joint head preferably encompassing the plate on both sides. Such a plane-parallel plate can be machined so precisely that easy movement is ensured with little play between the contact surfaces of the joint head and plate.

Zweckmäßig ist die Anordnung hiebei so getroffen, daß die das Langloch aufweisende planparallele Platte ungefähr in der Ebene des Fußes der Zungenschiene liegt. Vorzugsweise ist die Anordnung so getroffen, daß der Gelenkkopf im Bereiche seines Anlenkpunktes an das Anschlußstück einen die Schieberstange umgreifenden Bügel aufweist. Die Anordnung eines solchen Bügels wird dadurch erleichtert, daß das Langloch in einem Anschlußstück angeordnet ist, welches seitlich vom Fuß der Zungenschiene absteht und daher genügend Raum für den Bügel schafft. Dadurch wird in einfacher Weise die Verschlußklammer mit der Schieberstange verschieblich verbunden. Zweckmäßig ist hiebei der Bügel von einem mit dem Gelenkkopf ver­schweißten hakenförmig gebogenen Stab gebildet. Gemäß einer vorteilhaften Ausführung weist der Gelenkkopf beidseitig einen Bügel auf. Dies hat den Vorteil, daß die selbe Ver­schlußklammer rechts und links verwendet werden kann.The arrangement is expediently such that the plane-parallel plate having the elongated hole lies approximately in the plane of the foot of the tongue rail. The arrangement is preferably such that the joint head in the region of its articulation point on the connecting piece has a bracket encompassing the slide rod. The arrangement of such a bracket is facilitated in that the elongated hole is arranged in a connecting piece which protrudes laterally from the foot of the tongue rail and therefore creates enough space for the bracket. As a result, the locking clip is slidably connected to the slide rod. The bracket is expediently formed by a hook-shaped rod welded to the joint head. According to an advantageous embodiment, the joint head has a bracket on both sides. This has the advantage that the same locking clip can be used on the right and left.

Gemäß der Erfindung kann der Zapfen, mittels welchem die Zungenschiene am Gelenkkopf angelenkt ist, außermittig in einem im Langloch geführten, vorzugsweise quadratischen, Kulissenstein gelagert sein. Durch Verdrehen des Kulissen­steines kann der Abstand zwischen dem Anlenkzapfen des Gelenkkopfes und der Zungenschiene justiert werden. Wenn dieser Kulissenstein in der Draufsicht quadratisch ausge­bildet ist, so ergeben sich vier Justierstellungen und es kann daher das Justieren in kleineren Stufen erfolgen. Dadurch, daß das Langloch in einem gesonderten Anschlußstück angeordnet ist, welches präziser bearbeitet werden kann als der Schienenfuß selbst, können solche feinen Einstellstufen der Justierung, mittels des quadratischen Kulissensteines wirksam ausgenützt werden. Wenn das Langloch in einem nicht präzisiert bearbeiteten Teil, wie zum Beispiel im Schienen­fuß, angeordnet ist, wird die Feinfühligkeit der Justierung nicht erreicht.According to the invention, the pin, by means of which the tongue rail is articulated on the joint head, can be mounted off-center in a sliding block, preferably square, guided in the elongated hole. By turning the sliding block, the distance between the pivot pin of the joint head and the tongue rail can be adjusted. If this sliding block is square in plan view, there are four adjustment positions and adjustment can therefore be carried out in smaller steps. Because the elongated hole is arranged in a separate connecting piece, which can be machined more precisely than the rail base itself, such fine adjustment stages of the adjustment can be effectively used by means of the square sliding block. If the elongated hole is arranged in a part that has not been precisely machined, such as in the rail foot, the sensitivity of the adjustment is not achieved.

Gemäß einer bevorzugten Ausbildung der Erfindung ist das Anschlußstück mit dem Steg der Zungenschiene verschraubt. Dies hat den Vorteil, daß die Schraublöcher im Steg der Zungenschiene kaum eine Schwächung der Zungenschiene bewirken und es tritt auch der Vorteil auf, das eine Justierung des Abstandes des Anlenkzapfens des Gelenkkopfes durch einfaches Beilegen von Distanzblechen zwischen dem Steg der Zungen­schiene und dem Anschlußstück erfolgen kann. Hiebei ist die Ausbildung gemäß der Erfindung zweckmäßig so getroffen, daß das Anschlußstück von zwei ungefähr im rechten Winkel zueinanderstehenden Platten, welche an ihren Enden mit Seitenwangen verschweißt sind, gebildet ist, wobei die eine Platte zwischen den Seitenwangen das Langloch aufweist und die andere Platte Löcher für das Anschlußstück mit dem Steg der Zungenschiene verbindende Schrauben aufweist. Auf diese Weise wird ein stabiles und starres Anschlußstück geschaffen und eine präzise Führung des Anlenkzapfens des Gelenkkopfes im Langloch gewährleistet.According to a preferred embodiment of the invention, the connector is screwed to the web of the tongue rail. This has the advantage that the screw holes in the web of the tongue rail hardly cause a weakening of the tongue rail and there is also the advantage that the distance between the pivot pin of the joint head can be adjusted by simply inserting spacer plates between the web of the tongue rail and the connecting piece . Hiebei the design according to the invention is expediently made such that the connecting piece is formed by two plates approximately at right angles to one another, which are welded to side walls at their ends, one plate having the elongated hole between the side walls and the other plate having holes for the connector with the web of the tongue rail connecting screws. In this way, a stable and rigid connecting piece is created and precise guidance of the pivot pin of the joint head in the elongated hole is ensured.

Es kann aber auch gemäß der Erfindung das Anschlußstück mit dem Fuß der Zungenschiene verbunden sein, wobei es den Fuß überlappt und sich ungefähr in der Ebene des Fußes erstreckt.But it can also be connected to the foot of the tongue rail according to the invention, wherein it overlaps the foot and extends approximately in the plane of the foot.

Das Verschlußstück kann an der Außenseite des Steges der Backenschiene festgeschraubt sein. Auf diese Weise ist somit das Verschlußstück in seiner Lage starr festgelegt, wobei sich der Zapfen des Gelenkkopfes im Langloch frei verlagern und immer in der gleichen Relativlage zum Verschlußstück verbleiben kann. Zweckmäßig ist hiebei gemäß der Erfindung die Anordnung so getroffen, daß das Verschlußstück unterhalb des Schienenfußes der Backenschiene liegt und mit einem an den Steg der Backenschiene angeschraubten Flansch einen einstückigen Bauteil bildet, welcher den Fuß der Backen­schiene umgreift.The closure piece can be screwed onto the outside of the web of the stock rail. In this way, the closure piece is rigidly fixed in its position, the pin of the joint head being freely displaced in the elongated hole and can always remain in the same position relative to the closure piece. Appropriately, according to the invention, the arrangement is such that the closure piece lies below the rail foot of the stock rail and forms a one-piece component with a flange screwed to the web of the stock rail, which engages around the foot of the stock rail.

Die erfindungsgemäße Weichenbetätigungsvorrichtung kann für Weichenzungen oder Zungenschienen Anwendung finden. Da es auch bei der Zungenschiene wesentlich ist, daß der Schienen­fuß nicht durch ein Langloch geschwächt wird. Ebenso kann die erfindungsgemäße Weichenverstelleinrichtung auch bei beweg­lichen Herzstückspitzen angewendet werden.The switch operating device according to the invention can be used for switch tongues or tongue rails. Since it is also essential for the tongue rail that the rail foot is not weakened by an elongated hole. Likewise, the switch adjustment device according to the invention can also be used with movable centerpiece tips.

In der Zeichnung ist die Erfindung anhand von Ausführungsbei­spielen schematisch erläutert.In the drawing, the invention is explained schematically using exemplary embodiments.

Fig.3 und 4 zeigen einen Querschnitt durch Backenschiene und Zungen­schiene in geschlossenem Zustand bei einer etwas abge­wandelten Ausführungsform. Fig.5 und 6 zeigen das Anschluß­stück in Seitenansicht und Draufsicht. Fig.7 zeigt einen Gleitstein.1 and 2 show a cross section through the stock rail and tongue rail and a top view in the open position. 3 and 4 show a cross section through the stock rail and tongue rail in the closed state in a somewhat modified embodiment. Fig. 5 and 6 show the connector in side view and top view. Fig. 7 shows a sliding block.

Bei der Ausführungsform nach Fig.1 und 2 stellt 1 die Backen­schiene und 2 die Zungenschiene dar. 3 ist die Schieberstange und 4 die Verschlußklammer, deren Gelenkkopf 5 über einen Zapfen 6 mit der Zungenschiene 2 gelenkig verbunden ist.In the embodiment according to FIGS. 1 and 2, 1 represents the stock rail and 2 the tongue rail. 3 is the slide rod and 4 is the locking clip, the joint head 5 of which is articulated to the tongue rail 2 via a pin 6.

An den Zungenschienensteg 7 ist ein Anschlußstück 8 ange­schraubt, wobei die Schraublöcher mit 9 angedeutet sind. Das Anschlußstück 8, welches in Fig.5 und 6 in größerem Maßstab dargestellt ist, weist zwei planparallele Platten 10 und 11 auf, wobei in der Platte 10 ein Langloch 12 vorgesehen ist, in welches der Zapfen 6 eingreift. Die beiden Platten 10 und 11 sind mittels angeschweißter Seitenwangen 13 miteinander verbunden. Der Gelenkkopf 5 weist einen Bügel 14 auf, welcher hakenförmig die Schieberstange 3 umgreift und damit den Gelenkkopf 5 mit der Schieberstange verbindet. Die Verschluß­klammer 4 ist somit verschieblich mit der Schieberstange 3 verbunden.A connector 8 is screwed to the tongue rail web 7, the screw holes being indicated by 9. The connecting piece 8, which is shown on a larger scale in FIGS. 5 and 6, has two plane-parallel plates 10 and 11 on, wherein an elongated hole 12 is provided in the plate 10, in which the pin 6 engages. The two plates 10 and 11 are connected to one another by means of welded-on side cheeks 13. The joint head 5 has a bracket 14 which engages around the slide rod 3 in a hook-shaped manner and thus connects the joint head 5 to the slide rod. The locking clip 4 is thus slidably connected to the slide rod 3.

15 ist das Verschlußstück, in welchem die Schieberstange 3 und die Verschlußklammer 4 geführt sind. In der Offenstellung liegt der Verschlußklammerkopf 16 der Verschlußklammer 4 in einer Ausnehmung 17 der Schieberstange 3. In der Verschluß­stellung (Fig.3 und 4) liegt der Verschlußklammerkopf 16 an der Mündung 18 des Verschlußstückes 15 an, so daß die Zungen­schiene 2 in Anlage an die Backenschiene gehalten wird. Das Verschlußstück 15 ist mit einem Flansch 19, der an der Außenseite der Backenschiene 1 festgeschraubt wird, zu einem einstückigen Bauteil 20 vereinigt, welcher den Schienenfuß 21 der Backenschiene umgreift.15 is the closure piece in which the slide rod 3 and the closure clip 4 are guided. In the open position, the closure clip head 16 of the closure clip 4 lies in a recess 17 of the slide rod 3. In the closed position (FIGS. 3 and 4), the closure clip head 16 lies against the mouth 18 of the closure piece 15, so that the tongue rail 2 is in contact with the Stock rail is held. The closure piece 15 is combined with a flange 19 which is screwed onto the outside of the stock rail 1 to form a one-piece component 20 which engages around the rail foot 21 of the stock rail.

Die Verschlußstellung der Zungenschiene 2 ist in Fig.3 und 4 dargestellt. Die Ausführungsform nach Fig.3 und 4 unter­scheidet sich von der Ausführungsform nach Fig.1 und 2 lediglich dadurch, daß das Anschlußstück 22 am Schienenfuß 23 der Zungenschiene festgeschraubt ist. Dieses Anschlußstück 22 besteht aus einem gekröpften Lappen, der sich in der Ebene des Schienenfußes 23 erstreckt.The closed position of the tongue rail 2 is shown in Figures 3 and 4. The embodiment according to FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 only in that the connecting piece 22 is screwed onto the rail foot 23 of the tongue rail. This connector 22 consists of a cranked tab which extends in the plane of the rail foot 23.

In Fig.1 bis 4 ist der Bügel 14 an einer Seite des Gelenk­kopfes 5 angeordnet. Dieser Bügel 14 ist in ein Loch 24 des Gelenkkopfes 5 eingesetzt und mit dem Gelenkkopf 5 ver­schweißt. Es kann auch der Bügel an beiden Seiten angeordnet sein, so daß für Rechts- und Linksverschluß die selbe Ver­schlußklammer 4 verwendet werden kann, wie dies mit 14′ in Fig.4 angedeutet ist.1 to 4, the bracket 14 is arranged on one side of the joint head 5. This bracket 14 is inserted into a hole 24 of the joint head 5 and welded to the joint head 5.
