Description
Die Erfindung bezieht sich auf eine Oberbau-Zungenvorrichtung mit einer Backenschiene, einer in eine Regelschiene wie Rillenschiene übergehenden Zungenschiene, einer Leitschiene, einer die Zungenschiene regelschienenseitig insbesondere über ein Keilelement kraftschlüssig aufnehmenden Halterung und einer die Zungenschiene gleitend abstützenden Gleiteinrichtung wie Gleitplatte.The invention relates to a superstructure tongue device with a stock rail, a tongue rail in a control rail such as grooved rail, a guide rail, the tongue rail rule rail side, in particular via a wedge element frictionally receiving support and a tongue rail slidingly supporting slide like sliding plate.
Eine entsprechende Oberbau-Zungenvorrichtung ist der
Aus der
Aufgrund des voluminösen Blockes müssen bei nachträglichen Schweißarbeiten, die durch notwendige Reparaturen bedingt sein können, größere Volumen erwärmt werden, um eine hinreichende Verbindung zu gewährleisten. Beim Schweißen mit zu großer AbkühJgeschwindigkeit - d. h. bei mangelnder Vorwärmung - entstehen jedoch in Schienenstählen Härterisse. Unabhängig hiervon ist durch das große Zerspanungsvolumen eine geringe Wirtschaftlichkeit gegeben.Due to the voluminous block must be heated in subsequent welding work, which may be due to necessary repairs, larger volumes to ensure a sufficient connection. When welding at too high a cooling rate - d. H. in the case of a lack of preheating - however, hardening cracks occur in rail steels. Irrespective of this, low economy is given by the large cutting volume.
Die
Eine Zungenvorrichtung in Monoblockweise ist aus
Der vorliegenden Erfindung liegt das Problem zu Grunde, eine Oberbau-Zungenvomchtüng der eingangs genannten Art sowie ein Verfahren zur Herstellung einer solchen so weiterzubilden, dass nur wenige Bauelemente zur Ausbildung der Vorrichtung benutzt werden müssen, ohne dass Einbußen in der Funktionstüchtigkeit in Kauf zu nehmen sind. Gleichzeitig sollen gute Materialeigenschaften gegeben sein bzw. diese nicht oder nicht wesentlich bei einer notwendigen Bearbeitung verändert werden. Ferner sollen Materialien zum Einsatz gelangen, die die optimale Geeignetheit für eine Oberbau-Zungenvorrichtung zeigen. Auch soll eine vereinfachte Fertigung ermöglicht werden.The present invention is based on the problem, a Oberbau Tungenvomchtüng of the aforementioned type and a method for producing such educate so that only a few components must be used to form the device without sacrificing the functionality are to be accepted , At the same time good material properties should be given or they are not or not significantly changed in a necessary processing. Furthermore, materials are to be used which show the optimum suitability for a superstructure tongue device. Also, a simplified production is to be made possible.
Erfindungsgemäß wird das Problem im Wesentlichen dadurch gelöst, dass die Leitschiene ein bearbeiteter Abschnitt eines aus insbesondere Schienenstahl bestehenden Walzprofils ist, das regelschienenseitig einen der Regelschiene entsprechenden Querschnitt aufweist und in diese bündig übergeht. Dabei handelt es sich bei dem Walzprofil vorzugsweise um eine Konstruktionsschiene wie Dickstegschiene oder Vollschiene oder um eine Rechteckschiene z.B. eines Querschnitts von 180 x 180 mm2.According to the invention, the problem is essentially solved in that the guide rail is a machined section of a rolling profile consisting of, in particular, rail steel is, the rule rail side has one of the control rail corresponding cross-section and goes into this flush. In this case, the rolled section is preferably a construction rail such as a thick-web rail or solid rail or a rectangular rail, for example a cross-section of 180 × 180 mm 2 .
Abweichend vom vorbekannten Stand der Technik wird zur Herstellung der Leitschiene ein Walzprofil wie Konstruktionsschiene als Ausgangsmaterial benutzt, das gute Materialeigenschaften und hohe mechanische Gütewerte aufweist, wie diese vom Schienenstahl bekannt sind. Auch liegt ein homogenes Gefüge vor, so dass eine Neigung zur Rissbildung nicht gegeben ist. Durch die Verwendung von insbesondere Schienenstahl bleiben bewährte Schweißkonstruktionen erhalten, so dass sämtliche Elemente mit den für ihre Funktion am besten geeigneten Werkstoffen ausgeführt werden können. Insbesondere kann weiterhin für die Gleiteinrichtung wie Gleitplatte ein gewalztes Blech in verschleißfester Stahlsorte zum Einsatz gelangen, eine Möglichkeit, die bei der Ausbildung von Oberbau-Zungenvorrichtungen in Monoblockbauweise nicht möglich ist. Auch ist im Vergleich zu Monoblockkonstruktionen eine wirtschaftlichere Herstellung gegeben, da der Bearbeitungs- wie Zerspanungsaufwand in Grenzen gehalten wird.Notwithstanding the prior art, a rolled section such as construction rail is used as a starting material for the production of the guide rail, which has good material properties and high mechanical quality values, as they are known from rail steel. Also, there is a homogeneous structure, so that a tendency to cracking is not given. The use of rail steel in particular preserves proven welded constructions so that all elements can be designed with the most suitable materials for their function. In particular, a rolled sheet in wear-resistant steel grade can continue to be used for the sliding device such as sliding plate, a possibility that is not possible in the formation of superstructure tongue devices in monoblock construction. Also, compared to monoblock constructions a more economical production is given, since the processing and machining costs are kept within limits.
In Weiterbildung der Erfindung ist vorgesehen, dass die das regelschienenseitige Ende der Zungenschiene aufnehmende Halterung wie Zungenadapter mit dem bearbeiteten Walzprofil wie der bearbeiteten Konstruktionsschiene verschweißt ist. Folglich liegt im Bereich der Verbindung der Zungenschiene mit dem Adapter eine scheinbare Monoblockkonstruktion vor, so dass die insoweit bestehenden Vorteile übernommen werden.In development of the invention it is provided that the rule rail side end of the tongue rail receiving holder such as tongue adapter is welded to the processed rolled section as the processed construction rail. Consequently, in the region of the connection of the tongue rail with the adapter, an apparent monobloc construction exists, so that the advantages that exist to this extent are taken over .
Alternativ besteht die Möglichkeit, dass die Halterung ein umgeschmiedeter Abschnitt des Walzprofils ist. Die Möglichkeit, eine getrennt hergestellte Halterung mit dem bearbeiteten Walzprofil durch z. B. Schraubverbindung kraftschlüssig zu verbinden, ist gleichfalls in Betracht zu ziehen.Alternatively, there is the possibility that the holder is a reforged portion of the rolled section. The possibility of a separately prepared holder with the processed rolled profile by z. B. to connect screw positively, is also to be considered.
Die Ausrichtung der Halterung einerseits zu dem bearbeiteten Walzprofil und andererseits zu dem von der Halterung aufzunehmenden Abschnitt der Zungenschiene ist derart, dass die im Bereich der Halterung verlaufende und sich in die Regelschiene fortsetzende Rille ausschließlich von dem bearbeiteten Walzprofil und dem Abschnitt der Zungenschiene begrenzt wird.The orientation of the holder on the one hand to the processed rolled section and on the other hand to be absorbed by the holder portion of the tongue rail is such that extending in the region of the bracket and continuing in the control rail groove is limited exclusively by the processed rolled section and the portion of the tongue rail.
Um die erforderliche Bearbeitung des Walzprofils durchführen zu können, auch dann, wenn es sich um eine Dickstegschiene als Ausgangsmaterial handelt, sieht eine Weiterbildung der Erfindung vor, dass das Walzprofil in Form einer Konstruktionsschiene von Zungenschienenspitze aus betrachtet vor der Halterung einen im Vergleich zum Verlauf in und nach der Aufnahme versetzten Verlauf aufweist, also ausgekröpft ist.In order to carry out the required processing of the rolled section, even if it is a thick bar rail as a starting material, provides a development of the invention, that the rolled section in the form of a construction rail of tongue rail tip from before the holder in comparison to the course in and after the recording staggered course, that is cranked.
Alternativ besteht die Möglichkeit, den gewünschten Verlauf des Konstruktionsprofils durch Schneiden wie autogenes Brennschneiden zu erzielen, so dass ein Biegen nicht erforderlich ist. Ein spanendes Bearbeiten schließt sich an. Ein Herstellen einer entsprechenden Kontur erfolgt insbesondere bei einem Rechteckwalzprofil als "Ausgangsschiene".Alternatively, it is possible to achieve the desired profile of the construction profile by cutting such as autogenous flame cutting, so that bending is not required. A machining process follows. A corresponding contour is produced in particular in the case of a rectangular rolling profile as "output rail".
Auch eine CDN-Bearbeitung des Watzprofils ist möglich, so dass Bearbeitungsschritte abweichend zu den zuvor beschriebenen Reihenfolgen ausgeführt werden können. Die erfindungsgemäße Oberbau-Zungenvorrichtung weist eine Konstruktion auf, die die Vorteile einer Monoblockkonstruktion ohne Übernahme deren Nachteile aufweist. Dabei können insbesondere geeignete Werkstoffe zum Einsatz gelangen, die einer optimalen Funktionstüchtigkeit genügen, ohne dass herstellungsbedingte Nachteile in Kauf genommen werden müssen.A CDN processing of the Watzprofils is possible, so that processing steps can be carried out deviating from the previously described sequences. The superstructure tongue device according to the invention has a construction which has the advantages of a monobloc construction without taking over its disadvantages. In this case, in particular suitable materials can be used, which satisfy an optimal functionality, without manufacturing-related disadvantages must be taken into account.
Insbesondere ist von Vorteil, dass die Leitschiene über die gesamte Lange der Zungenschiene bis hin zur Regelschiene aus einem Bauteil hergestellt ist, das im erforderlichen Umfang bearbeitet ist.In particular, it is advantageous that the guide rail is made over the entire length of the tongue rail up to the control rail of a component which is machined to the extent required.
Ein Verfahren zur Ausbildung eines Abschnitts einer Oberbau-Zungenvorrichtung, umfassend eine Backenschiene, eine in eine Regelschiene wie Rillenschiene übergehende Zungenschiene, eine Leitschiene, eine die Zungenschiene aufnehmende Halterung sowie eine die Zungenschiene gleitend zwischen der Backenschiene und der Leitschiene abstützende Gleiteinrichtung, zeichnet sich dadurch aus, dass aus einem Walzprofil aus Schienenstahl durch spanabhebende Bearbeitung die Leitschiene hergestellt wird, die in einen mit einem der Regelschiene entsprechenden Profil aufweisenden Abschnitt übergeht, der durch spanabhebende Bearbeitung eines Abschnittes des Walzprofils ausgebildet wird.A method for forming a portion of a superstructure tongue device comprising a stock rail, a tongue rail passing into a control rail such as a grooved rail, a guardrail, a holder receiving the tongue rail, and a slider slidably supporting the tongue rail between the stock rail and the guardrail are thereby characterized in that the guide rail is produced from a rolled section of rail steel by machining, which passes into a section having a profile corresponding to the control rail, which is formed by machining a section of the rolled section.
Dabei kann vor dem insbesondere spanabhebenden Bearbeiten des Walzprofils dieses zur Erzielung eines gewünschten Verlaufs der Leitschiene gebogen werden. Insbesondere besteht die Möglichkeit, dass das Walzprofil vor der zerspanenden Bearbeitung durch z.B. autogenes Brennschneiden seine Grundkontur erhält. Ferner kann nach der spanabhebenden Bearbeitung das Walzprofil mit der Halterung verbunden wie verschweißt und sodann das Walzprofil zur Erzielung des gewünschten Verlaufs gebogen werden.It can be bent to achieve a desired course of the guide rail before the particular machining of the rolled section. In particular, there is the possibility that the rolled section may be subject to machining by e.g. autogenous flame cutting receives its basic contour. Further, after the machining, the rolled section may be connected to the support as welded, and then the rolled section may be bent to achieve the desired course.

Den Fig. 1a und 1b sind in Draufsicht wesentliche Elemente einer Oberbau-Zungenvorrichtung grundsätzlich bekannter Konstruktion zu entnehmen. Dies bedeutet, dass die Oberbau-Zungenvorrichtung eine Leitschiene 10 und eine Backenschiene 12 und eine Zungenschiene 14 umfasst, die auf einer Gleitplatte 16 gleitend verstellbar ist. Zum Verstellen der Zungenschiene 14 können nicht näher bezeichnete übliche Stelleinrichtungen benutzt werden. Die Zungenschiene 14 ist wurzelseitig in einer Halterung 18 fixiert, d. h. entsprechend der Fig. 4 über ein Keilelement 20 in der Halterung 18 festgelegt, wie diese beispielhaft in der
Außerhalb der Oberbau-Zungenvorrichtung schließen sich die Schienenabschnitte in Regelschienen wie Rillenschienen an, die durch Schweißverbindung mit den Schienenabschnitten in gewohnter Weise verbunden werden können.Outside the superstructure tongue device, the rail sections connect to control rails such as grooved rails, which can be connected by welding with the rail sections in the usual way.
Erfindungsgemäß ist nun vorgesehen, dass die Leitschiene 10 in der gesamten Oberbau-Zungenvorrichtung bis hin zum regelschienenseitigen Ende 22 ein Abschnitt eines Walzprofils insbesondere in Form einer Konstruktionsschiene wie Dickstegschiene 24 ist, die durch Bearbeiten die gewünschte Profilierung erfährt.According to the invention, it is now provided that the
Mit anderen Worten wird ein Walzprofil aus Schienenstahl als Ausgangsmaterial benutzt, das insbesondere durch spanende Bearbeitung den innerhalb der Oberbau-Zungenvorrichtung gewünschten Geometrieverlauf erfährt, um einerseits die Leitschiene 10 auszubilden und andererseits regelschienenseitig ein Profil zu erhalten, das dem der Regelschiene entspricht. Dieses Profil ist in Fig. 1b mit dem Bezugszeichen 26 gekennzeichnet.In other words, a rolled section made of rail steel is used as the starting material, which undergoes the desired within the superstructure tongue device geometry especially by machining to form the one hand, the
Vor der zerspanenden Bearbeitung des Walzprofils 24, das nachstehend vereinfacht als Konstruktionsschiene bezeichnet wird, kann dieses im erforderlichen Umfang gebogen werden, und zwar derart, dass sich eine Auskröpfung unmittelbar vor der Halterung 18 für die Zungenschiene 14 - auch Zungenadapter genannt - ergibt, wie aus der Fig. 1b ersichtlich wird, oder aber entsprechend der Fig. 7 und 8 einen gewünschten Konturverlauf durch z.B. Schneiden eines entsprechenden Profils erhalten.Before the machining of the rolled
Aus der Fig. 1b und einem Vergleich der Fig. 2 bis Fig. 5 wird einerseits der Verlauf der Konstruktionsschiene 24 in Bezug auf seinen Steg 28 und andererseits erkennbar, in welchem Umfang dieser zu bearbeiten ist, um die gewünschte Endgeometrie entlang der Zungenvorrichtung zu gewinnen. Dabei wird insbesondere aus der Prinzipdarstellung gemäß Fig. 5 und der rechten Schnittdarstellung in Fig. 1b offenbar, dass im regelschienenseitigen Endbereich eine Geometrie vorliegt, die der der an die Stoßstelle 22 anzuschweißenden Regelschiene entspricht.From FIG. 1 b and a comparison of FIGS. 2 to 5, on the one hand the course of the
Im Bereich der Zungenspitze bis hin zu dem Zungenadapter 18 weist die Leitschiene 10 nicht näher gekennzeichnete Stufen auf, auf denen die Gleitplatte 16 abstützbar ist, die insbesondere durch Schweißen mit der Leitschiene 10 und der Backenschiene 12 verbunden sein kann. Dabei kann die Gleitplatte 16 im eigentlichen Sinne aus kleineren und größeren Gleitplattenabschnitten 30, 32, 34 bestehen, wie die Fig. 6 verdeutlicht.In the region of the tip of the tongue up to the
Der Zungenadapter 18 selbst ist mit der Konstruktionsschiene 24 verschweißt (Fig. 4) und nimmt erwähntermaßen insbesondere durch Keilklemmplatten 20 die Zungenschiene 14 in ihrem regelschienenseitigen, also wurzelseitigen Ende klemmend auf. Die in diesem Bereich verlaufende und sich in die Regelschiene fortsetzende Rille 36 wird dabei wie folgt begrenzt. Rillenflanke 38 einerseits und Fahrflanke 40 der Rille 36 andererseits werden von Abschnitten der Konstruktionsschiene 24 bzw. der Zungenschiene 14 gebildet. Auch ist der Rillenboden 42 der Rille 36 ein Abschnitt der Konstruktionsschiene 24, so dass der Zungenadapter 18 selbst die Rille 36 nicht unmittelbar begrenzt. Vielmehr verläuft der Zungenadapter 18 entlang Unterseite 42 und rillenabgewandter Außenseite 44 der Zungenschiene 14 und ist einerseits mit dem Steg 28 der Konstruktionsschiene 24 und andererseits mit deren Fuß 46 verschweißt.The
Ferner ist erkennbar, dass sich die bearbeitete Konstruktionsschiene 24 in Längsrichtung betrachtet zu beiden Seiten des Zungenadapters 18 erstreckt.It can also be seen that the machined
Verläuft die Biegung der Konstruktionsschiene 24 von der Zungenschienenspitze aus betrachtet unmittelbar vor dem Zungenadapter 18, so ist entsprechend der Fig. 6 ein Verlauf im Bereich des Zungenadapters 18 gleichfalls möglich. Erstere Konstruktion ist jedoch als bevorzugt zu bezeichnen.If the bending of the
Als Konstruktionsprofil kommt insbesondere eine Dickstegschiene (Typ D 180/105) in Frage. Andere Konstruktionsschienen wie Vollkopfschienen, Vollschienen oder ähnliche sind gleichfalls geeignet.As a construction profile is in particular a thick bar rail (type D 180/105) in question. Other structural rails such as full-head rails, solid rails or the like are also suitable.
In den Fig. 7 und 8 ist als Konstruktionsprofil ein Rechteckwalzprofil aus Schienenstahl zur Realisierung der erfindungsgemäßen Lehre mit einer Kantlänge XY von z.B. 180 x 180 mm2 benutzt worden. Unabhängig hiervon werden entsprechend dem Ausführungsbeispiel der Fig. 1 bis 6 für gleiche Elemente gleiche Bezugszeichen verwendet. Dabei wird die Kontur und der Verlauf der Leitschiene 10 sowie des Bereichs, in dem der Zungenkloben 18 mit dem Konstruktionsprofil verbunden wie verschweißt ist, sowie der regelschienenseitige dem Profil 26 einer Rillenschiene entsprechende Bereich 50 durch z.B. autogenes Brennschneiden des Ausgangsprofils 124 oder ähnliche Verfahren und anschließendes Zerspanen hergestellt. Die in den Randbereichen vorliegenden Profile, also einerseits die Leitschiene 10 im Bereich der Zungenspitze und andererseits das Rillenschienenprofil 26 im regelschienenseitigen Ende der Zungenvorrichtung, sind durch die Schnittdarstellungen der Fig. 7 klar erkennbar. Dies ergibt sich auch aus der perspektivischen Darstellung gemäss Fig. 8, in der entsprechend der Fig. 6 auch Gleitplattenabschnitte 32, 34 eingezeichnet sind.In FIGS. 7 and 8, a rectangular roller section made of rail steel has been used as construction profile for the realization of the teaching according to the invention with an edge length XY of, for example, 180 × 180 mm 2 . Regardless of this, according to the embodiment of FIGS. 1 to 6, the same reference numerals for the same elements used. In this case, the contour and the course of the
Ferner wird verdeutlicht, dass die Zungenschiene 14 im Schrägstoß in den Fahrkopf 48 des endseitigen Abschnitts 50 des Walzprofils 124 übergeht, dessen Profil 26 dem der Regelschiene entspricht. Folglich weist das Profil 26 den Fahrkopf 48, Rillenkopf 52 sowie zwischen diesen verlaufende Rille 54 auf, die in die Rille 36 übergeht, wie dies anhand der Fig. 4 verdeutlicht worden ist.Furthermore, it is clarified that the
