Abstract
Description
Die Erfindung bezieht sich auf eine Anordnung zum Niederhalten einer zwischen Flügelschienen verlaufenden und auf einer Unterlage wie Gleitstuhl abstützbaren Herzstückspitze, insbesondere beweglicher wie federbeweglicher Herzstückspitze eines Herzstücks einer Weiche oder Kreuzung.The invention relates to an arrangement for holding down a between wing rails running centerpiece tip that can be supported on a base such as a sliding chair, in particular movable and spring-movable centerpiece tip of a crossover core or crossing.
Bei den heutzutage üblichen federbeweglichen Herzstücken wird die Herzstückspitze oder der Herzstückblock zwischen Flügelschienen auf einer Unterlage wie Gleitstuhl abgestützt, wohingegen die Flügelschienen weitgehend ortsfest von Unterlagen wie Rippenplatten ausgehen. Auch besteht die Möglichkeit, Flügelschienen fest auf Gleistühlen, auf denen die Herzstückspitze verschoben wird, zu befestigen.In the spring-moving frogs common today, the frog tip or the Centerpiece block supported between wing rails on a base such as a sliding chair, whereas the wing rails are largely stationary from documents such as rib plates going out. There is also the possibility of fixed wing rails on slide chairs on which the Centerpiece tip is moved to attach.
Nach der DE 23 30 828C2 geht von einem Herzstück für Rillenschienenweichen ein Gestänge aus, das Flügelschienen durchsetzt und über das das Herzstück verstellbar ist.According to DE 23 30 828C2, a linkage starts from a centerpiece for grooved rail switches from, which penetrates wing rails and over which the centerpiece is adjustable.
In der DE-AS 1 272 951 wird ein verschwenkbares Herzstück beschrieben, das über ein unterhalb von Flügelschienen verlaufendes Gestänge verstellbar ist. DE-AS 1 272 951 describes a pivotable centerpiece that has a linkage running below wing rails is adjustable.
Federbewegliche Herzstückspitzen bzw. solche, die elastisch abgestützt sind, sind auch aus der DE 37 08 233 A1 bekannt.Spring-moving centerpiece tips or those that are elastically supported are also from the DE 37 08 233 A1 known.
Beim Einleiten von Schwingungen in Richtung der Mittelachsen der Gleiskörper kann eine Relativbewegung zwischen Herstückspitze und Flügelschienen im Bereich zwischen dem Gleitstuhl bzw. Rippenplatten, von denen die Flügelschienen ausgehen, auftreten.When vibrations are introduced in the direction of the central axes of the track body, a Relative movement between the tip and wing rails in the area between the Sliding chair or ribbed plates from which the wing rails originate occur.
Hierdurch können sich unterschiedliche Bedingungen im Überlaufbereich des Rades zwischen Herzstückspitze und Flügelschienen ausbilden. Dies wiederum hat zur Folge, dass die Herzstückspitze einem unerwünschten Verschleiß unterworfen ist.This can result in different conditions in the overflow area of the wheel Form the centerpiece tip and wing rails. This in turn means that the centerpiece tip is subject to undesirable wear.
Um diese Nachteile zu vermeiden, ist aus der WO 94/19542 bzw. DE 43 05 228 A1 eine federbewegliche Herzstückspitze bekannt, die von einer Mitnehmereinrichtung ausgeht, die sich unterseitig an den Flügelschienen abstützt, so dass sich eine quasi starre Einheit ausbildet. Um jedoch ein leichtgängiges Verstellen der Herzstückspitze von der einen Flügelschiene zur anderen Flügelschiene zu ermöglichen, wird die Mitnehmereinrichtung, die mittelbar über Tellerfedern gegenüber der Herzstückspitze abgestützt ist, von den Flügelschienen abgehoben.In order to avoid these disadvantages, WO 94/19542 and DE 43 05 228 A1 describe one known spring-moving centerpiece tip, which starts from a driver device, which itself is supported on the underside of the wing rails so that a quasi rigid unit is formed. Around however, an easy adjustment of the centerpiece tip from one wing rail to To enable another wing rail, the driver device, which is indirect Belleville washers supported against the centerpiece tip, lifted off the wing rails.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Anordnung zum Niederhalten einer Herzstückspitze der eingangs beschriebenen Art so weiterzubilden, dass mit konstruktiv einfachen Maßnahmen ein sicheres Niederhalten der Herzstückspitze gewährleistet ist, wobei gleichzeitig sichergestellt sein soll, dass zum Verstellen der Herzstückspitze von einer Flügelschiene zur anderen Flügelschiene eine gewünschte Leichtgängigkeit gegeben ist, ohne dass neben der Herzstückspitze zusätzliche Massen bewegt werden müssen.The problem underlying the present invention is an arrangement for holding down to develop a centerpiece tip of the type described in the introduction in such a way that it is constructive simple measures a safe hold down of the frog tip is guaranteed, whereby At the same time, it should be ensured that for adjusting the centerpiece tip by a wing rail to the other wing rail a desired smoothness is given without in addition to the centerpiece tip, additional masses have to be moved.
Das Problem wird erfindungsgemäß dadurch gelöst, dass die Herzstückspitze von einem Element durchsetzt ist, das zum Niederhalten der Herzstückspitze in Richtung der Unterlage kraftbeaufschlagt ist, und dass zum Verstellen der Herzstückspitze das Element in einer von diesem durchsetzten Durchbrechung in der Herzstückspitze derart anhebbar oder drehbar ist, dass diese im gewünschten Umfang verstellbar ist. Insbesondere ist vorgesehen, dass das Element sowohl die Herzstückspitze als auch die Flügelschienen durchsetzt, wobei das Element von einer sich abschnittsweise unterhalb der Flügelschienen erstreckenden Halterung ausgeht, die unterseitig über zumindest ein Federelement an zumindest einem Flügelschienenfuß abgestützt ist.According to the invention, the problem is solved in that the frog tip is penetrated by an element that is used to hold down the centerpiece tip in the direction of the Underlay is subjected to force, and that for adjusting the frog tip, the element in an opening penetrated by this in the frog tip can be raised or so is rotatable that it is adjustable to the desired extent. In particular, it is provided that the element penetrates both the frog tip and the wing rails, the Element of a bracket extending in sections below the wing rails goes out, the underside via at least one spring element on at least one wing rail foot is supported.
Um die Herzstückspitze verstellen zu können, um also das Element in der Durchbrechung der Herzstückspitze derart zu verlagern, dass das Element die Verstellbewegung nicht behindern kann, ist vorgesehen, dass die Halterung über ein Aggregat nach oben, also in Richtung des Flügelschienenkopfes verstellbar ist.In order to be able to adjust the centerpiece tip, that is, the element in the opening of the To shift the centerpiece tip in such a way that the element does not hinder the adjustment movement can, it is provided that the holder via an assembly upwards, that is in the direction of Wing rail head is adjustable.
Das Element selbst ist vorzugsweise stabförmig ausgebildet und weist im Verstellweg der Herzstückspitze in Richtung der Unterlage vorspringende Abschnitte wie Nocken auf, von denen sich eine beim Niederhalten der Herzstückspitze in ihrer an einer der Flügelschienen anliegenden Stellung im Bodenbereich der Durchbrechung abstützt. Hierdurch wird ein sicheres Niederhalten der Herzstückspitze gewährleistet, ohne dass ein flächiges Abstützen des Elements in der Durchbrechung erfolgen muss.The element itself is preferably rod-shaped and has in the adjustment path Intermediate protruding sections such as cams on, from one of them holding down the centerpiece tip in her on one of the wing rails supported position in the bottom area of the opening. This will make it a safe one The tip of the centerpiece is held down without the element being supported flatly must take place in the opening.
Nach einem weiteren vorteilhaften Vorschlag der Erfindung umfasst die Halterung einen sich unterhalb der Flügelschienen erstreckenden plattenförmigen Abschnitt, der über Federelemente wie Tellerfedern unterseitig an den Flügelschienenfüßen abgestützt ist. Ferner greift an den plattenförmigen Abschnitt der Halterung das Aggregat wie eine Kolben-Zylinder-Anordnung an, um den plattenförmigen Abschnitt entgegen der von den Federelementen hervorgerufenen Kraft verstellen zu können, wodurch die Federelemente zusammengedrückt werden. Anstelle einer Kolben-Zylinder-Anordnung kann selbstverständlich auch ein sonstiges Aggregat wie Stellmotor eingesetzt werden oder ein Verschieben kann mittels eines Magneten erfolgen.According to a further advantageous proposal of the invention, the holder includes one below the Wing rails extending plate-shaped section, such as spring elements Disc springs are supported on the underside of the wing rail feet. Furthermore, the plate-shaped section of the bracket the aggregate like a piston-cylinder arrangement to the plate-shaped section opposite to that caused by the spring elements To be able to adjust force, whereby the spring elements are compressed. Instead of A piston-cylinder arrangement can of course also be another unit such as Servomotor can be used or moving can be done by means of a magnet.
Die Halterung selbst erstreckt sich außenseitig entlang der Flügelschienen und weist Klemmbacken zum Erfassen des stabförmigen Elements auf. Ferner weist die Halterung im Bereich der Schienenfüße der Flügelschienen einen lichten Abstand auf, der größer als der Abstand zwischen äußeren Rändern der Flügelschienenfüße ist. Hierdurch ist sichergestellt, dass die Flügelschienenfüße die Auf- und Abbewegung der Halterung nicht behindern.The bracket itself extends on the outside along the wing rails and has clamping jaws to grasp the rod-shaped element. Furthermore, the holder in the area of Rail feet of the wing rails a clear distance that is greater than the distance between outer edges of the wing rail feet. This ensures that the Wing rail feet do not hinder the up and down movement of the bracket.
Damit beim Anheben bzw. Absenken des stabförmigen Elementes zum Niederhalten bzw. Freigeben der Herzstückspitze die Flügelschienen nicht beeinflußt werden können, ist des weiteren vorgesehen, dass unabhängig von der Stellung des stabförmigen Elementes dieses Durchbrechungen der Flügelschienen stets beabstandet durchsetzt.So that when raising or lowering the rod-shaped element for holding down or Releasing the frog tip the wing rails can not be influenced is the further provided that regardless of the position of the rod-shaped element Breakthroughs in the wing rails are always spaced apart.
Das die Halterung entgegen der von den Federelementen hervorgerufenen Kraft verstellende Aggregat selbst kann von einer Halterung ausgehen, die mittelbar oder unmittelbar mit den Flügelschienen in Verbindung steht. So kann die Halterung von einer Rippenplatte oder von Abstützungen der Flügelschienen wie Schwellen ausgehen. Vorzugsweise ist die Halterung über Klemmbacken an den Flügelschienenfüßen fixiert.That adjusts the holder against the force caused by the spring elements The unit itself can be based on a bracket that can be used directly or indirectly with the Wing rails are connected. So the holder of a ribbed plate or of Supports the wing rails like thresholds. Preferably, the bracket is over Clamping jaws fixed to the wing rail feet.
Ein weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass das stabförmig ausgebildete Element Vorsprünge wie Nocken aufweist, die durch Drehen des Elementes die Herzstückspitze in Richtung der Unterlage kraftbeaufschlagen oder zu denen die Herzstückspitze verstellbar ist.Another advantageous embodiment of the invention provides that the rod-shaped element has projections like cams, which by rotating the element the frog tip in the direction of Apply force to the pad or to which the centerpiece tip is adjustable.
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 result not only from the Claims, the features to be extracted from these - individually and / or in combination -, but also from the following description of one of the drawings preferred embodiment.

- a first cut through a frog tip and
- Fig. 2
- a second section through a frog tip.
Den Figuren sind Schnitte durch eine Herzstückspitze 10 zu entnehmen. Die Herzstückspitze
umfasst gewohnterweise einen beweglichen Herzstückblock 12, der zwischen Flügelschienen
14 und 16 verläuft. Der Herzstückblock bzw. die Herzstückspitze 12 ist auf einem Gleitstuhl 18
abgestützt, der im Ausführungsbeispiel als innere Schienenverspannung für die Flügelschienen
14 und 16 ausgebildet ist. Die Flügelschienen 14 und 16 selbst sind auf nicht dargestellten
Unterlagen wie Rippenplatten abgestützt, die ihrerseits auf Unterstützungen wie Schwellen
angeordnet sind. Insoweit wird jedoch auf hinlänglich bekannte Gleisoberbaukonstruktionen
verwiesen.The figures show sections through a
Um die Herzstückspitze 12 im erforderlichen Umfang auf dem Gleitstuhl 18 dann niederzuhalten,
wenn die Herzstückspitze 12 an der Flügelschiene 14 -wie dargestellt- oder an der
Flügelschiene 16 anliegen soll, ist ein vorzugsweise stabförmig ausgebildetes Element
vorgesehen, das sowohl die Herzstückspitze 12 als auch die Flügelschienen 14, 16 in
Durchbrechungen 22, 24 und 26 durchsetzt. Dabei fluchten die Durchbrechungen 22, 24 und 26
zueinander. Das Stabelement 22 geht von einer Halterung 28 aus, die im Ausführungsbeispiel
äußere Klemmbacken 30, 32, über die das Stabelement 20 festgespannt wird, sowie einen
unterhalb der Flügelschienen 14 und 16 verlaufenden plattenförmigen Abschnitt als Bodenplatte
34 umfasst. Die Halterung weist folglich im Schnitt eine die Flügelschienen 14, 16 umfassende
U-Geometrie auf. Zwischen den Klemmbacken 30, 32, die sich in den Laschenkammern der
Flügelschienen 14, 16 erstrecken, und dem plattenförmigen Abschnitt 34 sind ferner
Distanzstücke 36, 38 vorgesehen, wobei deren lichter Abstand größer als der Abstand zwischen
äußeren Rändern 40, 42 der Flügelschienenfüße 44, 46 ist. Durch diese Maßnahme soll
sichergestellt sein, daß eine Reibung zwischen der Halterung 28 und den Flügelschienenfüßen
44, 46 ausgeschlossen ist.In order to hold down the
Die Klemmbacken 30, 32, die Distanzstücke oder Zwischenplatten 36, 38 sowie die Bodenplatte
34 sind über Bolzen bzw. Schrauben 48, 50 miteinander verbunden bzw. verspannt.The
Die Bodenplatte 34 der Halterung 28 verläuft beabstandet zur Unterseite der Füße 44, 46 der
Flügelschienen 14 und 16. Ferner ist die Bodenplatte 34 und damit die Halterung 28 gegenüber
den Flügelschienen 14 und 16 über Federelemente wie Tellerfedern 52, 54 abgestützt. Als
Resultat wird die Halterung 28 bzw. das Stabelement 20 nach unten, also in Richtung des
Gleitstuhls 18 bzw. der Füße 44, 46 der Flügelschienen 14, 16 gezogen. Hierdurch bedingt
stützt sich das Stabelement 20 am Bodenbereich der Durchbrechung 22 der Herzstückspitze 12
ab, so daß die Herzstückspitze 12 auf dem Gleitstuhl 18 niedergehalten wird. Demgegenüber
durchsetzt das Stabelement 20 die Durchbrechung 24, 26 der Flügelschienen 14, 16
beabstandet.The
Um ein sicheres Niederhalten bei optimaler Krafteinleitung zu gewährleisten, weist das
Stabelement 20 in Richtung des Gleitstuhls 18 sich erstreckende Vorsprünge wie Nocken 56, 58
auf, die sich dann am Boden der Durchbrechung 22 der Herzstückspitze 12 abstützen, wenn die
Herzstückspitze 12 an der Flügelschiene 14 bzw. an der Flügelschiene 16 anliegt.In order to guarantee a safe hold down with optimal force transmission, this shows
Um ein leichtgängiges Verstellen der Herzstückspitze 12 zu ermöglichen, ohne dass das
stabförmige Element 20 eine Behinderung darstellen kann, kann aufgrund der erfindungsgemäßen
Konstruktion die Halterung 28 in einem Umfang angehoben werden, daß das
Stabelement 20 die Durchbrechung 22 der Herzstückspitze 12 weitgehend beabstandet
durchsetzt. Um die Halterung 28 und damit das Stabelement 20 anheben zu können, wird in die
Bodenplatte 34 eine Kraft eingeleietet, durch die die Tellerfedern 52 und 54 zusammengedrückt
werden. Hierzu geht von einer Halterung 60 ein Verstellaggregat in Form einer Zylinder-Kolben-Anordnung
aus, wobei der Kolben 64 über eine elastische Zwischenlage 66 in einer
bodenseitigen Aussparung 68 von der Bodenplatte 34 eingreift. Wird der Kolben des Aggregats
62 verschoben, so wird folglich die Bodenplatte 34 entgegen der Federkraft angehoben,
wodurch das Stabelement 22 angehoben und somit die Herzstückspitze 12 leichtgängig von der
Flügelschiene 14 zur Flügelschiene 16 verstellt werden kann oder umgekehrt.In order to enable easy adjustment of the
Unabhängig von der Stellung des Stabelements 20, also unabhängig davon, ob auf die
Halterung 28 allein die Kraft der Tellerfedern 52 oder die diesen entgegengerichtete und von
dem Antriebsaggregat 62 hervorgerufene Kraft einwirkt, durchsetzt das Stabelement 20 die
Durchbrechungen 24, 26 der Flügelschienen 14, 16 stets mit Spiel.Regardless of the position of the
Die Halterung 60 für das Antriebsaggregat 62 geht von den Flügelschienenfüßen 44, 46 aus,
wie die Fig. 2 verdeutlicht. Hierzu wird eine Aufnahme der Halterung 60, in der das Aggregat
62 fixiert ist, über Klemmbacken 72, 74 mit den Flügelschienenfüßen 44, 46 verbunden. Ferner
verläuft zwischen der Unterseite der Schienenfüße 44, 46 und der Aufnahme 70 eine Platte 76.The
