Description

Die Erfindung bezieht sich auf eine Schienenauszugsvorrichtung umfassend Backen- und Zugschiene und Regelschiene, die mittelbar oder unmittelbar mit der Zugschiene verbunden ist, wobei die Backenschiene und die Zugschiene gegeneinander längs verschieblich sind und quer zur Schienenlängsrichtung zueinander kraftbeaufschlagt aneindanderliegen.The invention relates to a rail extraction device comprising jaw and pull rail and control rail, which is directly or indirectly connected to the drawbar rail, wherein the stock rail and the drawbar are mutually longitudinally displaceable and aneindanderliegen to each other transverse to the rail longitudinal direction.

Schienenauszugsvorrichtungen - auch als Dehnungsstöße bezeichnet - werden z. B. im Bereich von Brücken eingebaut, um eine Relativbewegung zwischen Bauwerk und Gleis zu ermöglichen. Dabei ist grundsätzlich die Zungenschiene relativ zu der Backenschiene verschieblich angeordnet. Hierzu kann z. B. die Zungenschiene zwischen der Backenschiene und einer auf der gegenüberliegenden Seite ortsfest angeordneten Klemmbacke festgelegt werden. Zungenschienenfuß und Backenschienenfuß gehen dabei von einer gemeinsamen Grundplatte aus, wie z. B. die DE-A-1 534 052 verdeutlicht.Rail extension devices - also known as expansion joints - z. B. installed in the area of bridges to allow a relative movement between the structure and track. In principle, the tongue rail is displaceably arranged relative to the stock rail. For this purpose, z. B. the tongue rail between the stock rail and a fixedly arranged on the opposite side jaw are set. Tongue rail foot and jaw rail foot start from a common base plate, such. B. the DE-A-1 534 052 clarified.

Bei einer Schienenauszugsvorrichtung nach der WO-A-93/23624 kann eine Backenschiene zu einer Zungenschiene verschiebbar angeordnet werden, wobei die Zungenschiene entsprechend der Biegelinie der Backenschiene bearbeitet ist.In a rail extension device according to the WO-A-93/23624 a stock rail can be slidably arranged to a tongue rail, wherein the tongue rail is processed according to the bending line of the stock rail.

Einen Dehnungsstoß für Rillenschienen nach der DE-A-195 25 135 sieht einen mit einer Führungsplatte verschweißten Schienenabschnitt vor, wobei die Führungsplatte in Längsrichtung des Dehnungsstoßes auf einem Gleitstuhl verschiebbar angeordnet ist.An expansion joint for grooved rails after the DE-A-195 25 135 provides a welded to a guide plate rail section, wherein the guide plate is slidably disposed in the longitudinal direction of the expansion joint on a sliding chair.

Bei den bekannten Schienenauszugsvorrichtungen sind die Zungenschienen mit der sich anschließenden Regelschiene üblicherweise verschweißt. Ist durch Verschleiß der Zungenschiene ein Austausch erforderlich, so müssen aufwendige Arbeiten durchgeführt werden. Auch können nicht beliebige Materialien miteinander verschweißt werden, so dass sich der Nachteil ergibt, dass schwer schweißbare verschleißfeste Stähle dem Grunde nach nicht zum Einsatz gelangen.In the known rail extension devices, the tongue rails are usually welded to the adjoining control rail. If replacement is necessary due to wear of the tongue rail, expensive work must be carried out. Also, not any materials can be welded together, so that there is the disadvantage that hard-to-weld wear-resistant steels are basically not used.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Schienenauszugsvorrichtung der eingangs genannten Art so weiterzubilden, dass eine schnelle Austauschbarkeit der Zungenschiene möglich ist bzw. die Zungenschiene aus Materialien bestehen kann, die nicht verschweißbar sind oder aus nur schwer schweißbaren verschleißfesten Stählen bestehen.The present invention is based on the object, a rail extension device of the type mentioned in such a way that a quick replacement of the tongue rail is possible or the tongue rail may consist of materials that are not welded or made of hard to weld wear-resistant steels.

Zur Lösung der Aufgabe sieht die Erfindung im Wesentlichen vor, dass die Zungenschiene beabstandet zu ihrem an der Backenschiene anliegenden Bereich lösbar von einer Halterung aufgenommen ist und dass die Zungenschiene in der Halterung mit der in diese übergehenden Regelschiene oder einem Abschnitt dieser oder einem profilmäßig in die Regelschiene übergehenden Abschnitt der Halterung kraft- und formschlüssig verbunden ist.To solve the problem, the invention essentially provides that the tongue rail is spaced apart to its voltage applied to the stock rail area releasably received by a holder and that the tongue rail in the holder with the passing into this rule rail or a portion of this or a profile in the Standard rail transition section of the holder is positively and positively connected.

Abweichend von vorbekannten Schienenauszugsvorrichtungen wird zum Fixieren der Zungenschiene eine gesonderte Halterung benutzt, in der die Zungenschiene mit der Regelschiene lösbar mittelbar oder unmittelbar kraft- und formschlüssig verbunden ist. Dabei kann die Halterung selbst in einen Abschnitt der Regelschiene unmittelbar übergehen, so dass die lösbare Verbindung mit dem Abschnitt der Halterung und einem verbleibenden Abschnitt der Regelschiene erfolgt.Notwithstanding previously known rail extension devices for fixing the tongue rail, a separate holder is used in which the tongue rail with the control rail is releasably connected directly or indirectly positively and positively. In this case, the holder can pass directly into a portion of the control rail, so that the detachable connection is made with the portion of the holder and a remaining portion of the control rail.

Es wird folglich eine Konstruktion benutzt, die von Rillenschienenweichen bekannt ist, wie diese z. B. der EP-B-0 603 883 oder der DE-A-101 14 683 zu entnehmen ist.It is therefore a construction used, which is known from grooved rail points, as these z. B. the EP-B-0 603 883 or the DE-A-101 14 683 can be seen.

Sind die vorbekannten Halterungen für reine Weichenkonstruktionen in Form von Rillenschienenweichen bestimmt, wird erfindungsgemäß eine Schienenauszugsvorrichtung mit einer Zungenschiene vorgeschlagen, deren Profil einer Vignolschiene entsprechen kann. Aber auch für Dehnungsstöße für Gleise aus Rillenschienen ist die erfindungsgemäße Lehre anwendbar. In diesem Fall ist insbesondere vorgesehen, dass die Backenschiene verschiebbar zu der Zungenschiene angeordnet ist, wobei die Zungenschiene auf einer Abstützung aufliegt, die ihrerseits innere Führung als erste Führung für die Backenschiene ist. Außenseitig liegt die Backenschiene zumindest abschnittsweise an einer äußeren Führung als zweite Führung an. Dabei ist die zweite Führung mit einer Grundplatte verbunden wie verschweißt, von der eine Beischiene ausgeht, die ihrerseits mit der ersten Führung vorzugsweise in Form einer Führungsleiste insbesondere ebenfalls durch Schweißen verbunden ist. Zum sicheren Befestigen sollte dabei die Führungsleiste mit ihrem backenschienenfernliegenden Längsrandbereich in eine geometrisch angepasste Längsaussparung der Beischiene eingreifen.Are the previously known brackets intended for pure turnouts in the form of grooved rails, a rail extension device is proposed according to the invention with a tongue rail, the profile of which correspond to a Vignolschiene can. But also for expansion joints for rails made of grooved rails, the teaching of the invention is applicable. In this case, it is particularly provided that the stock rail is slidably disposed to the tongue rail, wherein the tongue rail rests on a support, which in turn is inner guide as the first guide for the stock rail. On the outside, the stock rail is at least partially on an outer guide as a second guide. In this case, the second guide is connected to a base plate as welded, emanating from a Beischiene, which in turn is preferably also connected by welding to the first guide in the form of a guide rail. For secure fastening, the guide strip should engage with its longitudinal edge region remote from the cheek rail in a geometrically adapted longitudinal recess of the insert rail.

Um ein horizontales Verstellen der Zungenschiene zu vermeiden, können zwischen backenschienenabgewandter Seitenfläche der Zungenschiene und zugewandter Innenfläche der Beischiene Abstandselemente wie Leisten eingebracht werden, die insbesondere mit der Führungsleiste verschraubt werden. Ein vertikales Verstellen der Zungenschiene kann dadurch unterbunden werden, dass die Zungenschiene die Backenschiene im Kopfbereich unterschlägt.In order to avoid a horizontal adjustment of the tongue rail, spacer elements such as strips can be introduced between baking side facing away from the side surface of the tongue rail and facing inner surface of Beischiene, which are screwed in particular with the guide rail. A vertical adjustment of the tongue rail can be prevented, that the tongue rail suppresses the stock rail in the head area.

Durch die erfindungsgemäße Lehre ergibt sich insbesondere für Rillenschienenauszugsvorrichtungen eine einfache Konstruktion, die aufgrund der Austauschbarkeit der Zungenschiene überaus wartungsfreundlich ausgebildet ist. Insbesondere besteht die Möglichkeit, die Zungenschiene aus verschleißfestem Material herzustellen, das nicht oder nur sehr schwer schweißbar ist. Dabei ist eine sichere Führung der Backenschiene gewährleistet, wobei die innere Führung eine Doppelfunktion insoweit ausübt, dass nicht nur die Backenschiene gegen ein horizontales Verstellen gesichert wird, sondern gleichzeitig eine Abstützung für die Zungenschiene erfolgt.The teaching of the invention results in particular for Rillenschienenauszugsvorrichtungen a simple construction that is designed to be extremely easy to maintain due to the interchangeability of the tongue rail. In particular, it is possible to produce the tongue rail made of wear-resistant material that is difficult or impossible to weld. In this case, a secure guidance of the stock rail is ensured, wherein the inner guide exerts a dual function insofar that not only the stock rail is secured against horizontal adjustment, but at the same time there is a support for the tongue rail.

Zusätzlich kann die Führungsleiste über von der Grundplatte ausgehende Abstützungen wie Plattenelemente abgestützt werden, so dass ein Verbiegen in vertikaler Richtung auch bei starker Beanspruchung ausgeschlossen ist.In addition, the guide rail can be supported on the base plate outgoing supports such as plate elements, so that bending in the vertical direction is excluded even under heavy use.

Die Halterung sollte blockartig ausgebildet sein und weist insbesondere zwei in Schienenlängsrichtung verlaufende kanalartige Aussparungen auf, wobei in einer Aussparung die Zungenschiene mit ihrer Wurzel sowie ein Keilelement eingebracht sind, über das die Zungenschiene fixiert bzw. form- und kraftschlüssig mit der sich angrenzenden Regelschiene bzw. einem Abschnitt dieser verbunden wird. Das Keilelement wird sodann über abschnittsweise innerhalb der zweiten kanalförmigen Aussparung verlaufende Befestigungselemente wie Schrauben fixiert.The holder should be block-like and in particular has two channel-like recesses extending in the longitudinal direction of the rail, wherein the tongue rail with its root and a wedge element are introduced in a recess via which the tongue rail is fixed or positively and non-positively connected to the adjacent control rail or a section of this is connected. The wedge element is then fixed by means of fastening elements extending in sections within the second channel-shaped recess, such as screws.

Zum Austausch der Zungenschiene ist es nur erforderlich, dass die Abstandselemente bzw. Leisten, die mit der Führungsleiste vorzugsweise verschraubt sind, gelöst werden. Sodann werden die Keilelemente entfernt, so dass die Zungenschiene herausnehmbar und durch eine neue ersetzbar ist. Irgendwelche Arbeiten an der Backenschiene bzw. deren äußerer Führung sind demgegenüber nicht erforderlich.To replace the tongue rail, it is only necessary that the spacer elements or strips, which are preferably bolted to the guide bar, are released. Then the wedge elements are removed so that the tongue rail is removable and replaceable by a new one. Any work on the stock rail or its outer guide are not required in contrast.

Sollte die Halterung für die Zungenschienenwurzel bereichsweise eingehaust sein, so sind diesbezügliche Abdeckungen zu entfernen, um die Keilelemente und damit die Zungenschiene lösen und entfernen zu können.If the holder for the tongue rail root is partially housed, so coverings are relevant to remove in order to solve the wedge elements and thus the tongue rail and can remove.

Unabhängig hiervon sollte die Zungenschiene aus einem hochverschleißfesten Stahl wie Bainit, Manganhartstahl, vergütetem Schienenstahl (R 350 HT), vergütetem Feinkornbaustahl, z. B. DILLIDUR (Stahl der Dillinger Hütte GTS, Deutschland), HARDOX (Stahl der SSAB Oxelösund AB, Schweden, XAR (Stahl der ThyssenKrupp Steel AG, Deutschland) in Güten 400 bis 500 bestehen.Regardless of this, the tongue rail should be made of a highly wear-resistant steel such as bainite, manganese steel, tempered rail steel (R 350 HT), coated fine grain steel, z. B. DILLIDUR (steel of Dillinger Hütte GTS, Germany), HARDOX (steel of SSAB Oxelösund AB, Sweden, XAR (steel of ThyssenKrupp Steel AG, Germany) in grades 400 to 500 exist.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen -für sich und/oder in Kombination-, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention will become apparent not only from the claims, the features to be taken from them-alone and / or in combination-but also from the following description of a preferred embodiment to be taken from the drawing.

Um in Abhängigkeit von herrschenden Temperaturen eine Relativverstellung zwischen den Backenschienen 12, 14 und den in die Regelschienen 16, 18 übergehenden Zungenschienen 21 zu ermöglichen, werden die Backenschienen 12, 14 nach außen von den Zungenschienen 21 weggeführt, so dass ungeachtet der wirksamen Länge der Backenschienen 12, 14 ein stetiger Übergang von den Zungenschienen 21 bzw. deren Spitzen 20 in die Backenschienen 12, 14 erfolgt.The rail extension device 10 comprises in the usual way jaw rails 12, 14 which are longitudinally displaceable to in rails 16, 18 transitional tongue rails 21, of which in the illustrations in Fig. 3 and 4 a tip portion 20 and root portion 22 are shown in section. In order to enable a relative adjustment between the stock rails 12, 14 and the tongue rails 21 passing into the control rails 16, 18 as a function of prevailing temperatures, the stock rails 12, 14 are led away from the tongue rails 21 to the outside, so that regardless of the effective length of the stock rails 12, 14 a continuous transition from the tongue rails 21 and the tips 20 in the jaw rails 12, 14 takes place.

Die Regelschienen 16, 18 bestehen aus Schienenstahl. Da die Zungenschienen 21 einem besonderen Verschleiß ausgesetzt sind, können diese aufgrund der erfindungsgemäßen Lehre aus schwer schweißbaren oder überhaupt nicht schweißbaren Materialien, insbesondere hochfesten Stählen bestehen, da die Zungenschienen 21 in die Regelschienen 16, 18 ohne Schweißverbindung form- und kraftschlüssig übergehen. Hierzu sind sogenannte als Halterungen 24 zu bezeichnende Zungenadapter vorgesehen, über die die Zungenschienen in ihren Wurzelbereichen 22 bündig mittelbar oder unmittelbar in die Regelschienen 16, 18 übergehen. Dabei ist es nicht zwingend erforderlich, dass die Regelschiene unmittelbar mit der Zungenschiene 21 verbunden wird. Vielmehr kann der Adapter die Geometrie eines Abschnitts der Regelschiene in deren Fahrbereich aufweisen, um sodann in seiner Stirnfläche mit der außerhalb des Adapters verlaufenden Regelschiene 16, 18 verbunden wie verschweißt zu werden.The rule rails 16, 18 are made of rail steel. Since the tongue rails 21 are exposed to a particular wear, these may consist of difficult to weld or not weldable materials, especially high-strength steels due to the teaching of the invention, since the tongue rails 21 in the control rails 16, 18 without weld connection form and locks. For this purpose, so-called tongue holders are to be designated as brackets 24, via which the tongue rails in their root areas 22 flush directly or indirectly in the control rails 16, 18 pass. It is not absolutely necessary that the control rail is connected directly to the tongue rail 21. Rather, the adapter may have the geometry of a portion of the control rail in the driving range, to then be connected in its end face to the outside of the adapter extending control rail 16, 18 as welded.

Zungenschienenende (Bereich 22) und Abschnitt der Regelschiene 16, 18 sollten in der Halterung 24 im Schrägstoß 25 von insbesondere 30° ineinander übergehen.Tongue rail end (area 22) and portion of the control rail 16, 18 should merge in the holder 24 in the oblique joint 25 of 30 ° in particular.

Der Adapter ist blockartig ausgebildet und weist eine in Längsrichtung der Schienen verlaufende kanalartige Aussparung 26 auf, in die der wurzelseitige Bereich 22 der Zungenschiene 21 einlegbar ist. Neben dem Zungenschienenabschnitt 22 wird sodann ein Keilelement wie Keilklemmplatte 28 in die kanalförmige Aussparung 26 eingebracht wird. Die Keilklemmplatte 28 wird mittels einer oder bevorzugterweise mehrerer Schrauben 30 angezogen, die mit einer Mutter oder einem Kopf 32 in eine T-Nut 34 in den Adapter eingreift, so dass ein einfaches Anziehen und Fixieren möglich ist.The adapter is block-shaped and has a channel-like recess 26 running in the longitudinal direction of the rails, into which the root-side region 22 of the tongue rail 21 can be inserted. Next to the tongue rail portion 22, a wedge member such as wedge clamp plate 28 is then inserted into the channel-shaped recess 26. The wedge clamping plate 28 is tightened by means of one or more preferably a plurality of screws 30, which engages with a nut or a head 32 in a T-groove 34 in the adapter, so that a simple tightening and fixing is possible.

Die Halterung 24 bzw. der Adapter selbst ist im Ausführungsbeispiel auf dem Fuß 36 der Regelschiene 16 abgestützt und mit dieser über Unterstützungskeile 38 insbesondere durch Schweißen verbunden. Der Fuß 36 geht seinerseits von einer Grundplatte 40 aus und ist vorzugsweise mit dieser verschweißt.The holder 24 or the adapter itself is supported in the exemplary embodiment on the foot 36 of the control rail 16 and connected thereto via support wedges 38, in particular by welding. The foot 36 in turn starts from a base plate 40 and is preferably welded to it.

Zu beiden Seiten der erwähntermaßen als Adapter zu bezeichnenden Halterung 24 verlaufen leistenartige Wandungen 42, 44, die mit der Grundplatte 40 verbunden wie verschweißt sind. Außenseitig können des Weiteren Abstützungen von der Grundplatte 40 ausgehen, wie die Abstützung 46 in Fig. 4 rein prinzipiell verdeutlicht.On both sides of the above-mentioned as adapter to be designated support 24 strip-like walls 42, 44 which are connected to the base plate 40 as welded. On the outside, furthermore, supports can originate from the base plate 40, like the support 46 in FIG Fig. 4 purely in principle clarified.

Die in der zeichnerischen Darstellung in Fig. 4 dargestellte rechte Begrenzungswandung 42 weist in ihrem Kopfbereich ein Flacheisenelement 48 auf, das sich in Richtung der Zungenschiene 21 bzw. dessen Wurzelabschnitt 22 erstreckt und hat die Funktion einer Beischiene. Das Flacheisenelement 48 ist mit der Begrenzungswandung 42 verschweißt.The in the graphic representation in Fig. 4 shown right boundary wall 42 has in its head area a flat iron element 48 which extends in the direction of the tongue rail 21 and its root portion 22 and has the function of a Beischiene. The flat iron element 48 is welded to the boundary wall 42.

Der Bereich des Adapters bzw. der Halterung 24 ist weitgehend eingehaust, so dass sich Montagekästen 52 ergeben, die sich aus den Wandungen 42, 44 als Seitenwandungen, der Leiste 48 sowie ein plattenförmiges von der oberen Stirnfläche der Wandung 44 ausgehendes Flachelement 54 zusammensetzen. Dabei sind die auch als leistenförmig zu bezeichnenden Elemente 48, 54 mit den Wandungen 42, 44 verschraubt bzw. verschweißt, wie sich aus der Fig. 1 ergibt.The area of the adapter or the holder 24 is largely enclosed, so that there are mounting boxes 52, which consist of the walls 42, 44 as side walls, the bar 48 and a plate-shaped from the upper end face of the wall 44th Assemble outgoing flat element 54. The elements 48, 54, which may also be referred to as strip-shaped, are screwed or welded to the walls 42, 44, as can be seen from FIG Fig. 1 results.

Außerhalb des Adapters bzw. der Halterung 24 verläuft entlang des Schienenauszugs eine Beischiene 50, die in die Wandung 42 übergehen kann. Die Beischiene 50 geht dabei von der Grundplatte 40 aus. Unabhängig hiervon ist es nicht erforderlich, dass die Grundplatte 40 durchgehend von Anfang bis zum Ende des Schienenauszugs verläuft. Vielmehr können mehrere zueinander beabstandete Grundplattenabschnitte vorgesehen sein, die ihrerseits durch die Beischiene 50 bzw. die Wandung 42 verbunden sind.Outside the adapter or the holder 24 extends along the rail extension a Beischiene 50, which can pass into the wall 42. The Beischiene 50 starts from the base plate 40. Regardless, it is not necessary that the base plate 40 extends continuously from the beginning to the end of the rail extension. Rather, a plurality of mutually spaced base plate sections may be provided, which in turn are connected by the Beischiene 50 and the wall 42.

Die Zungenschiene 21 wird innerhalb der Halterung 24 auf der Bodenfläche 56 der kanalartigen Aussparung 26 abgestützt. Durch die Verkeilung der Zungenschiene 21 ist sowohl eine horizontale als auch eine vertikale Unbeweglichkeit gegeben. Außerhalb der Halterung 24 wird die Zungenschiene 21 auf einer Führungsleiste 58 abgestützt, die von der Beischiene 50 ausgeht. Dabei erstreckt sich die auch als Gleitplatte zu bezeichnende Führungsleiste 58 mit ihrem beischienenseitig verlaufenden Längsrand in eine geometrisch angepasste nut- oder schlitzförmige Aufnahme 60 der Beischiene 50. Die Führungsleiste 58 dient gleichzeitig als seitliche Abstützung der Backenschiene 12, die außenseitig, also auf gegenüberliegender Seite, von einer zweiten Führung in Form eines vertikal verlaufenden Plattenelementes 62 abgestützt ist. Somit kann sich die Backenschiene 12 zwischen der Führungsleiste 58 und der Führungsplatte 62, die ebenfalls als Führungsplatte bezeichnet werden kann, in Längsrichtung verschieben, also ausdehnen und zusammenziehen. Eine horizontale Unverrückbarkeit ergibt sich dadurch, dass die Backenschiene 12 zwischen der Führungsleiste 58 und der Führungsplatte 62 seitlich begrenzt ist. Ein vertikales Verstellen wird dadurch unterbunden, dass die Backenschiene 12 mit einem Fußlängsrandbereich 64 in einen geometrisch angepassten Ausschnitt 66 der Führungsplatte 62 eingreift. Dabei ist die Aussparung bzw. der Ausschnitt 64 bodenseitig von der Grundplatte 40 begrenzt.The tongue rail 21 is supported within the holder 24 on the bottom surface 56 of the channel-like recess 26. By wedging the tongue rail 21 is given both a horizontal and a vertical immobility. Outside the holder 24, the tongue rail 21 is supported on a guide bar 58, which starts from the Beischiene 50. The guide strip 58, which can also be referred to as a sliding plate, extends with its longitudinal edge running on the side of the clip into a geometrically adapted slot-shaped or slot-shaped receptacle 60 of the insertion bar 50. The guide strip 58 simultaneously serves as a lateral support for the stock rail 12, that is on the outside, ie on the opposite side. is supported by a second guide in the form of a vertically extending plate member 62. Thus, the stock rail 12 between the guide bar 58 and the guide plate 62, which can also be referred to as a guide plate, move in the longitudinal direction, ie expand and contract. A horizontal immutability results from the fact that the stock rail 12 is laterally limited between the guide bar 58 and the guide plate 62. A vertical adjustment is prevented by the fact that the stock rail 12 engages with a Fußlängsrandbereich 64 in a geometrically adapted cutout 66 of the guide plate 62. In this case, the recess or the cutout 64 is bounded on the bottom side by the base plate 40.

Auf der Führungsleiste 58 wird die Schienenzunge 21 abgestützt. Eine horizontale Unbeweglichkeit oder weitgehende Unbeweglichkeit ergibt sich dadurch, dass zwischen beischienenseitig verlaufender Außenseite 68 und zugewandter Innenfläche 70 der Beischiene 50 Abstandsleisten 72 angeordnet werden, die vorzugsweise mittels Schraubverbindungen mit der Führungsleiste 58 lösbar verbunden sind. Eine horizontale Verstellung der Zungenschiene 21 wird dadurch unterbunden, dass die Zungenschiene 21 den Kopf 74 der Backenschiene 12 unterschlägt.On the guide bar 58, the rail tongue 21 is supported. A horizontal immobility or substantial immobility results from the fact that between Beischienenseitig extending outside 68 and facing inner surface 70 of the Beischiene 50 spacer strips 72 are arranged, which are preferably releasably connected by means of screw with the guide bar 58. A horizontal adjustment of the tongue rail 21 is prevented by the tongue rail 21 suppressing the head 74 of the stock rail 12.

Aus der zeichnerischen Darstellung gemäß Fig. 3 ergibt sich des Weiteren, dass die Führungsleiste 58 über plattenförmige Abstützungen 76 abgestützt sein kann, die von der Grundplatte 40 ausgehen. Ferner ist die Führungsplatte 62 außenseitig über Stützen 78 gesichert.From the graphic representation according to Fig. 3 results further that the guide bar 58 may be supported by plate-shaped supports 76 which extend from the base plate 40. Furthermore, the guide plate 62 is secured on the outside via supports 78.

Der Fig. 5 ist ein Schnitt entlang der Linie D-D in Fig. 1 zu entnehmen, der vor der Halterung 24 bzw. dem Montagekasten 52 verläuft. Man erkennt die Beischiene 50 mit der von dieser ausgehenden Führungsleiste 58, auf der ein Abschnitt 23 der Zungenschiene 21 abgestützt ist. An der Führungsleiste 58 liegt die Backenschiene 12 mit ihrer zungenschienenseitigen Stegseite an. Gegenüberliegend erstreckt sich in Längsrichtung der Backenscheine 12 die Führungsplatte 62. Ferner ist ein die Führungsleiste 58 abstützendes Plattenelement 76 dargestellt.The Fig. 5 is a section along the line DD in Fig. 1 to remove, which extends in front of the holder 24 and the mounting box 52. One recognizes the Beischiene 50 with the emanating from this guide bar 58 on which a portion 23 of the tongue rail 21 is supported. On the guide bar 58, the stock rail 12 is located with her tongue rail side web page. Opposite extends in the longitudinal direction of the jaws 12, the guide plate 62. Furthermore, a guide bar 58 abstützendes plate member 76 is shown.

Aus der Fig. 2 ergibt sich des Weiteren, dass am Ende der Schienenauszugsvorrichtung 10, also in der Zeichnung vor der Zungenspitze, ein Entwässerungskasten 80 angeordnet ist, der mit den Innenräumen der Schienenauszugsvorrichtung 10 verbunden ist, die von der Backenschiene 12 und der Führungsplatte 62 bzw. der Beischiene 50 und einer äußeren Verkleidung 80 begrenzt sind. Auch besteht eine Verbindung zwischen den von den Abstützungen 76 begrenzten Bereichen und den zuvor beschriebenen Außenkammern. Ferner kann unmittelbar zur Backenschiene 12 benachbart, also in der von der Führungsplatte 62 und der Backenschiene 12 begrenzten Außenkammer ein Kurzschlussverbinder 84 verlaufen, also ein Stromkabel mit großem Querschnitt. Der Kurzschlussverbinder gewährleistet die elektrische Leitfähigkeit zwischen Backenschiene 12 und Regelschiene 16.From the Fig. 2 It also follows that at the end of the rail extension device 10, ie in the drawing in front of the tongue tip, a drainage box 80 is arranged, which is connected to the interiors of the rail extension device 10, of the stock rail 12 and the guide plate 62 and the Beischiene 50th and an outer panel 80 are limited. There is also a connection between the areas bounded by the supports 76 and the previously described outer chambers. Furthermore, directly adjacent to the stock rail 12, ie in the outer chamber delimited by the guide plate 62 and the stock rail 12, a short-circuit connector 84 can run, that is to say a power cable with a large cross section. The short-circuit connector ensures the electrical conductivity between the stock rail 12 and the control rail 16.
