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
Bei einer Schienenauszugsvorrichtung nach der
Einen Dehnungsstoß für Rillenschienen nach der
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
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.

In den Figuren ist rein prinzipiell eine Schienenauszugsvorrichtung 10 dargestellt, die Rillenschienen betrifft, ohne dass hierdurch eine Einschränkung der erfindungsgemäßen Lehre erfolgen soll. Vielmehr gilt diese auch für andere Schienenprofile, insbesondere Vignolschienen.In the figures, a
Die Schienenauszugsvorrichtung 10 umfasst in gewohnter Weise Backenschienen 12, 14, die zu in Regelschienen 16, 18 übergehenden Zungenschienen 21 längsverschieblich sind, von denen in den Darstellungen in
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

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-
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
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

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
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
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
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
