Definitions
- wing rails Centerpiece for switches or crossings with a centerpiece tip arranged between wing rails, in particular a movable and spring-movable centerpiece tip, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are fastened and sections of the wing rails and the frog tip rest between the fastening plates holding the wing rails on an at least partially plate-shaped driver device fastened to the frog tip and a foot-side section of the frog tip extending in the main axis direction is partially surrounded by the driver device.
- fastening plates such as e.g. Rib plates are fastened and sections of the wing rails and the frog tip rest between the fastening plates holding the wing rails on an at least partially plate-shaped driver device fastened to the frog tip and a foot-side section of the frog tip extending in the main axis direction is partially surrounded by the driver device.
- a centerpiece of the type described above is known from DE-AS 1 272 951.
- An extension of the tailpiece is screwed to two hold-down brackets that extend below the wing rails to prevent the tip of the frog from springing up.
- the frog tip or the frog block is supported between wing rails on a base such as a sliding chair, whereas the wing rails largely originate from documents such as rib plates. There is also the possibility that wing rails are firmly attached to the sliding chairs on which the frog tips are moved.
- the present invention is based on the problem of developing a frog of the type described at the outset in such a way that the same conditions are always formed in the transition region between wing rails and frog tip, so that in particular it is ensured that a relative movement - viewed in the direction of the main axis of the wing rails or the Centerpiece tip - is largely excluded.
- the problem is solved in that the foot-side section of the frog tip extending in the main axis direction moves through the plate-shaped area of the driver device, a force acting on the section in this way preferably by means of plate springs which extend between the underside of the plate and an abutment, that when the centerpiece is passed through a rail vehicle, the centerpiece tip rests on the driver device which rests on the underside of the wing rails.
- the section is preferably a pin extending from the foot area of the frog tip, on which preferably act the leaf springs which hold the frog tip down on the driver device or other suitable spring elements.
- the measures according to the invention ensure that the wing rails and the frog tip always rest on the top of the driver device, so that a rigid unit is formed, which excludes a relative movement between the wing rail and frog tip in the direction of the main axis of the track sections; because on the top of the driver device, the wing rail and thus also the centerpiece tip always remain when driving through a rail vehicle.
- the centerpiece tip is consequently held on the driver device lying on the underside of the wing rails, so that lifting is not possible.
- the spring element holding the centerpiece tip on the upper side of the driver device extends between the underside of the plate-shaped region of the driver device and an abutment, such as a disk, which starts from the pin.
- the driver device can be adjusted in the direction of the main axis of the centerpiece tip in such a way that the wing rails do not more on top of the driver device. Rather, the driver device is pressed down by the frog tip and thus the wing rails, so that there is no contact between the driver device and the wing rails when the frog tip is pivoted relative to the wing rails.
- the driver device can be part of a housing on which a drive device such as a cylinder-piston arrangement is supported, through which the force caused by the spring is overcome when force is applied in the direction of the underside of the housing, thereby removing the housing from the frog tip and thus is pulled away from the wing rails and thus releases the latter.
- a drive device such as a cylinder-piston arrangement
- FIG. Shows a section of a frog with a frog tip (10) and the wing rails (12) and (14) assigned to it, but this does not limit the invention. Rather, the idea to be derived from the invention can also be applied to other track sections.
- the centerpiece tip (10) is designed to be movable as well as spring-movable.
- the wing rails (12) and (14) are fastened on fastening plates, not shown, whereas the frog tip (10) is movably arranged on sliding chairs, also not shown.
- the mounting plate and sliding chair can form a single unit.
- the wing rails (12) or (14) and the centerpiece tip (10) bend, a different deflection occurring in particular when a rail vehicle or its wheels to be considered only on the wing rail (12) or . (14) and do not yet roll on the centerpiece tip (10).
- different overflow areas can be formed, which lead to undesired wear of the frog tip (10) and thus inevitably to an exchange of the frog block.
- this relative movement in the direction of the main axis (16) of the frog tip (10) is prevented by the fact that between or in the area of the usually available documents, i. H. Fastening plates or sliding chairs, driver devices (18) are arranged, which start from the centerpiece tip, but on which the wing rails (12) and (14) are loosely arranged.
- the frog tip (16) is movable in the manner described below, but at least when driving on the frog essentially as a unit with the driver device (18) so that wing rails (12), (14) and frog tip (10) on one Place the surface firmly.
- the driver device (18) consists of an upper plate (20), from which legs (22) and (24) extend, which in turn are connected by a base plate (26). Other suitable constructions for the driver device (18) are also possible.
- the wing rails (12) and (14) can rest on the top (28) of the plate (20) with their feet (30) and (32). This takes place at least in relation to the wing rail being used.
- the centerpiece tip (10) has a pin (34) on the underside which passes through a corresponding recess (36) in the plate (20).
- the driver device (18) is thus fixed to the frog tip (10), but is movably connected in the manner described below.
- the centerpiece tip (10) is continuously subjected to a force in the direction of the driver device (18), which in the exemplary embodiment is caused by disc springs (40), (42) which are located between the underside (44) of the plate ( 20) and an abutment (46) extending from the pin (34).
- the corresponding wing rail (12) or (14) When driving through a rail vehicle, the corresponding wing rail (12) or (14) rests on the upper side (28) of the plate (20), which is pressed towards the frog tip (10) in such a way that the frog tip (10) can speak on the top (28).
- the driver device (18) Since the driver device (18) must also be moved when the frog tip (10) is adjusted, it should be ensured that static friction between the wing rails (12) and (14), i.e. the feet (30) and (32) and the top (28) of the plate (44) is reduced or avoided.
- a cylinder-piston arrangement (46), (48) is supported, the piston (48) with the pin (34) of the frog tip (10) is connected.
- the cylinder (46) can, for example, be attached to the driver device (18), specifically in the exemplary embodiment on the legs (22), (24) or the base plate (26). If a fluid now acts on the piston (48) in the direction of the arrow (50), the prestressing force caused by the plate springs (40) is overcome, so that the driver device (18) can be moved relative to the frog tip (10) because this lies in front of and behind the driver device (18) on sliding chairs. By pulling down the driver device (18), the feet (30) and (32) of the wing rails (12) and (14) are free, so that the tip of the frog (10) can be easily adjusted.
- driver devices (18) in a switch or crossing area depends on their design and requirements. Corresponding driver devices (18) can thus always be provided between successive sliding chairs or fastening plates. Alternatively, there is the possibility of arranging corresponding driver devices at a greater distance, that is to say not assigning such to each sliding chair or each mounting plate. Also, only one driver device (18) can be provided directly in the transition area.
- a centerpiece for switches or crossings with a centerpiece tip (10) arranged between wing rails (12, 14), in particular a movable and spring-movable centerpiece tip is generally proposed, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are attached.
- a driver device emanates from the Her Foundationspitze, on which the wing rail being used rests.

Abstract
Description
Herzstück für Weichen oder Kreuzungen mit zwischen Flügelschienen angeordneter Herzstückspitze, insbesondere beweglicher wie federbeweglicher Herzstückspitze, wobei die Flügelschienen im wesentlichen stationär auf Befestigungsplatten wie z.B. Rippenplatten befestigt sind und zwischen die Flügelschienen haltenden Befestigungsplatten Abschnitte der Flügelschienen und der Herzstückspitze auf einer zumindest bereichsweise plattenförmigen, an der Herzstückspitze befestigten Mitnehmereinrichtung aufliegen und ein sich in Hauptachsenrichtung erstreckender fußseitiger Abschnitt der Herzstückspitze von der Mitnehmereinrichtung bereichsweise umgeben ist.Centerpiece for switches or crossings with a centerpiece tip arranged between wing rails, in particular a movable and spring-movable centerpiece tip, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are fastened and sections of the wing rails and the frog tip rest between the fastening plates holding the wing rails on an at least partially plate-shaped driver device fastened to the frog tip and a foot-side section of the frog tip extending in the main axis direction is partially surrounded by the driver device.
Ein Herzstück zuvor beschriebener Art ist aus der DE-AS 1 272 951 bekannt. Dabei ist eine Verlängerung des Herstücks mit zwei Niederhaltewinkeln verschraubt, die sich unterhalb von Flügelschienen erstrecken, um ein Hochfedem der Herzstückspitze zu verhindern.A centerpiece of the type described above is known from DE-AS 1 272 951. An extension of the tailpiece is screwed to two hold-down brackets that extend below the wing rails to prevent the tip of the frog from springing up.
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. Es besteht auch die Möglichkeit, daß Flügelschienen fest auf den Gleitstühlen, auf denen die Herzstückspitzen verschoben werden, befestigt sind.With the spring-moving frogs common today, the frog tip or the frog block is supported between wing rails on a base such as a sliding chair, whereas the wing rails largely originate from documents such as rib plates. There is also the possibility that wing rails are firmly attached to the sliding chairs on which the frog tips are moved.
Federbewegliche Herzstückspitzen bzw. solche, die elastisch abgestützt sind, sind aus der DE 37 08 233 A1 oder DE 41 42 276 A1 bekannt.Spring-movable centerpiece tips or those that are elastically supported are known from DE 37 08 233 A1 or DE 41 42 276 A1.
Bei Einleiten von Schwingungen in Richtung der Mittelachsen der Gleiskörper kann eine Relativbewegung zwischen Herzstückspitze und Flügelschienen im Bereich zwischen den Gleitstühlen bzw. Rippenplatten, von denen die Flügelschienen ausgehen, auftreten, wodurch sich unterschiedliche Bedingungen im Überlaufbereich des Rades zwischen Herzstückspitze und Flügelschienen ausbilden können. Hierdurch besteht die Gefahr, daß die Herzstückspitzen einem unerwünschten Verschleiß unterworfen sind.When vibrations are introduced in the direction of the central axes of the track body, a relative movement between the centerpiece tip and wing rails can occur in the area between the sliding chairs or ribbed plates from which the wing rails originate, as a result of which different conditions can form in the overflow area of the wheel between the centerpiece tip and wing rails. As a result, there is a risk that the frog tips are subject to undesirable wear.
Der vorliegenden Erfindung liegt das Problem zugrunde, ein Herzstück der eingangs beschriebenen Art so weiterzubilden, daß sich im Übergangsbereich zwischen Flügelschienen und Herzstückspitze stets gleiche Bedingungen ausbilden, so daß insbesondere sichergestellt ist, daß eine Relativbewegung - betrachtet in Richtung der Hauptachse der Flügelschienen bzw. der Herzstückspitze - weitgehend ausgeschlossen ist.The present invention is based on the problem of developing a frog of the type described at the outset in such a way that the same conditions are always formed in the transition region between wing rails and frog tip, so that in particular it is ensured that a relative movement - viewed in the direction of the main axis of the wing rails or the Centerpiece tip - is largely excluded.
Erfindungsgemäß wird das Problem dadurch gelöst, daß der sich in Hauptachsenrichtung erstreckende fußseitige Abschnitt der Herzstückspitze den plattenförmigen Bereich der Mitnehmereinrichtung beweglich durchsetzt, wobei auf den Abschnitt derart vorzugsweise durch Tellerfedern, die sich zwischen der Unterseite der Platte und einem Widerlager erstrecken, eine Kraft einwirkt, daß beim Durchfahren des Herzstücks durch ein Schienenfahrzeug die Herzstückspitze auf der Mitnehmereinrichtung aufliegt, die unterseitig an den Flügelschienen anliegt.According to the invention, the problem is solved in that the foot-side section of the frog tip extending in the main axis direction moves through the plate-shaped area of the driver device, a force acting on the section in this way preferably by means of plate springs which extend between the underside of the plate and an abutment, that when the centerpiece is passed through a rail vehicle, the centerpiece tip rests on the driver device which rests on the underside of the wing rails.
Dabei ist der Abschnitt vorzugsweise ein vom Fußbereich der Herzstückspitze ausgehender Zapfen, auf dem vorzugsweise die die Herzstückspitze auf der Mitnehmereinrichtung niederhaltenden Blattfedern oder andere geeignete Federelemente einwirken.The section is preferably a pin extending from the foot area of the frog tip, on which preferably act the leaf springs which hold the frog tip down on the driver device or other suitable spring elements.
Durch die erfindungsgemäßen Maßnahmen ist sichergestellt, daß die Flügelschienen und die Herzstückspitze stets auf der Oberseite der Mitnehmereinrichtung aufliegen, so daß sich quasi eine starre Einheit ausbildet, die eine Relativbewegung zwischen Flügelschiene und Herzstückspitze in Richtung der Hauptachse der Gleisabschnitte ausschließt; denn auf der Oberseite der Mitnehmereinrichtung bleibt die Flügelschiene und damit auch die Herzstückspitze beim Durchfahren eines Schienenfahrzeuges stets liegen. Die Herzstückspitze wird folglich auf der unterseitig an den Flügelschienen anliegenden Mitnehmereinrichtung festgehalten, so daß ein Anheben nicht möglich ist.The measures according to the invention ensure that the wing rails and the frog tip always rest on the top of the driver device, so that a rigid unit is formed, which excludes a relative movement between the wing rail and frog tip in the direction of the main axis of the track sections; because on the top of the driver device, the wing rail and thus also the centerpiece tip always remain when driving through a rail vehicle. The centerpiece tip is consequently held on the driver device lying on the underside of the wing rails, so that lifting is not possible.
Das die Herzstückspitze auf der Oberseite der Mitnehmereinrichtung haltende Federelement erstreckt sich zwischen der Unterseite des plattenförmigen Bereichs der Mitnehmereinrichtung und einem von dem Zapfen ausgehenden Widerlager wie Scheibe.The spring element holding the centerpiece tip on the upper side of the driver device extends between the underside of the plate-shaped region of the driver device and an abutment, such as a disk, which starts from the pin.
Um trotz Vorhandensein der Mitnehmereinrichtung ein leichtgängiges Verstellen der Herzstückspitze zu ermöglichen, ohne daß eine Haftreibung zwischen Flügelschienen und Mitnehmereinrichtung auftritt, ist nach einem weiteren hervorzuhebenden Vorschlag der Erfindung vorgesehen, daß die Mitnehmereinrichtung zur Herzstückspitze in Richtung deren Hauptachse derart verstellbar ist, daß die Flügelschienen nicht mehr auf der Oberseite der Mitnehmereinrichtung aufliegen. Vielmehr wird die Mitnehmereinrichtung von der Herzstückspitze und somit den Flügelschienen nach unten gedrückt, so daß bei einem relativen Verschwenken der Herzstückspitze zu den Flügelschienen eine Berührung zwischen der Mitnehmereinrichtung und den Flügelschienen unterbleibt. Hierzu kann die Mitnehmereinrichtung Teil eines Gehäuses sein, an dem eine Antriebseinrichtung wie eine Zylinder-Kolben-Anordnung abgestützt ist, durch die bei Krafteinwirkung in Richtung der Unterseite des Gehäuses die von der Feder hervorgerufene Kraft überwunden wird, wodurch das Gehäuse von der Herzstückspitze und damit von den Flügelschienen weggezogen wird und somit letztere freigibt.In order to enable easy adjustment of the centerpiece tip without the stiction between the wing rails and driver device despite the presence of the driver device, it is provided according to a further proposal of the invention that the driver device can be adjusted in the direction of the main axis of the centerpiece tip in such a way that the wing rails do not more on top of the driver device. Rather, the driver device is pressed down by the frog tip and thus the wing rails, so that there is no contact between the driver device and the wing rails when the frog tip is pivoted relative to the wing rails. For this purpose, the driver device can be part of a housing on which a drive device such as a cylinder-piston arrangement is supported, through which the force caused by the spring is overcome when force is applied in the direction of the underside of the housing, thereby removing the housing from the frog tip and thus is pulled away from the wing rails and thus releases the latter.
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 them - individually and / or in combination - but also from the following description of a preferred exemplary embodiment which can be seen from the drawing.
In der einzigen Fig. ist ein Ausschnitt eines Herzstücks mit Herzstückspitze (10) und den diesem zugeordneten Flügelschienen (12) und (14) dargestellt Hierdurch erfolgt jedoch keine Einschränkung der Erfindung. Vielmehr ist der der Erfindung zu entnehmende Gedanke auch auf andere Gleisabschnitte übertragbar.The only FIG. Shows a section of a frog with a frog tip (10) and the wing rails (12) and (14) assigned to it, but this does not limit the invention. Rather, the idea to be derived from the invention can also be applied to other track sections.
Die Herzstückspitze (10) ist beweglich wie federbeweglich ausgebildet. Die Flügelschienen (12) und (14) sind auf nicht dargestellten Befestigungsplatten befestigt, wohingegen die Herzstückspitze (10) auf gleichfalls nicht dargestellten Gleitstühlen beweglich angeordnet ist. Befestigungsplatte und Gleitstuhl können dabei eine Einheit bilden.The centerpiece tip (10) is designed to be movable as well as spring-movable. The wing rails (12) and (14) are fastened on fastening plates, not shown, whereas the frog tip (10) is movably arranged on sliding chairs, also not shown. The mounting plate and sliding chair can form a single unit.
Zwischen den Befestigungsplatten und Gleitstühlen oder auf diesen, sofern eine elastische Abstützung erfolgt, biegen sich die Flügelschienen (12) bzw. (14) und die Herzstückspitze (10) durch, wobei eine unterschiedliche Auslenkung insbesondere dann erfolgt, wenn ein Schienenfahrzeug bzw. dessen in Betracht zu ziehende Räder nur auf der Flügelschiene (12) bzw. (14) und noch nicht auf der Herzstückspitze (10) abrollen. Hierdurch können sich unterschiedliche Überlaufbereiche ausbilden, die zu einem unerwünschten Verschleiß der Herzstückspitze (10) und damit zwangsläufig zu einem Austausch des Herzstückblocks führen.Between the mounting plates and sliding chairs or on these, provided there is an elastic Support is provided, the wing rails (12) or (14) and the centerpiece tip (10) bend, a different deflection occurring in particular when a rail vehicle or its wheels to be considered only on the wing rail (12) or . (14) and do not yet roll on the centerpiece tip (10). As a result, different overflow areas can be formed, which lead to undesired wear of the frog tip (10) and thus inevitably to an exchange of the frog block.
Erfindungsgemäß ist nun vorgesehen, daß diese Relativbewegung in Richtung der Hauptachse (16) der Herzstückspitze (10) dadurch unterbunden wird, daß zwischen oder im Bereich von den üblicherweise vorhandenen Unterlagen, d. h. Befestigungsplatten bzw. Gleitstühle, Mitnehmereinrichtungen (18) angeordnet sind, die von der Herzstückspitze ausgehen, auf denen jedoch die Flügelschienen (12) und (14) lose angeordnet sind. Dabei ist die Herzstückspitze (16) in nachstehend beschriebener Art und zwar beweglich, jedoch zumindest beim Befahren des Herzstückes im wesentlichen als Einheit mit der Mitnehmereinrichtung (18) ausgebildet, so daß Flügelschienen (12), (14) und Herzstückspitze (10) auf einer Fläche fest aufliegen.According to the invention it is now provided that this relative movement in the direction of the main axis (16) of the frog tip (10) is prevented by the fact that between or in the area of the usually available documents, i. H. Fastening plates or sliding chairs, driver devices (18) are arranged, which start from the centerpiece tip, but on which the wing rails (12) and (14) are loosely arranged. The frog tip (16) is movable in the manner described below, but at least when driving on the frog essentially as a unit with the driver device (18) so that wing rails (12), (14) and frog tip (10) on one Place the surface firmly.
Die Mitnehmereinrichtung (18) besteht aus einer oberen Platte (20), von der Schenkel (22) und (24) ausgehen, die ihrerseits über eine Bodenplatte (26) verbunden sind. Andere geeignete Konstruktionen für die Mitnehmereinrichtung (18) sind gleichfalls möglich.The driver device (18) consists of an upper plate (20), from which legs (22) and (24) extend, which in turn are connected by a base plate (26). Other suitable constructions for the driver device (18) are also possible.
Auf der Oberseite (28) der Platte (20) können die Flügelschienen (12) und (14) mit ihren Füßen (30) und (32) aufliegen. Dies erfolgt zumindest in bezug auf die befahrene Flügelschiene. Die Herzstückspitze (10) weist unterseitig einen Zapfen (34) auf, der eine entsprechende Aussparung (36) in der Platte (20) durchsetzt. Somit ist die Mitnehmereinrichtung (18) mit der Herzstückspitze (10) zwar fest, jedoch in nachstehend beschriebener Art beweglich verbunden.The wing rails (12) and (14) can rest on the top (28) of the plate (20) with their feet (30) and (32). This takes place at least in relation to the wing rail being used. The centerpiece tip (10) has a pin (34) on the underside which passes through a corresponding recess (36) in the plate (20). The driver device (18) is thus fixed to the frog tip (10), but is movably connected in the manner described below.
Um im Normalfall eine Relativbewegung zwischen der Herzstückspitze (10) und der Platte (20) auszuschließen, wirkt auf die Herzstückspitze (10) fortwährend eine Kraft in Richtung der Mitnehmereinrichtung (18), die im Ausführungsbeispiel durch Tellerfedern (40), (42) hervorgerufen wird, die sich zwischen der Unterseite (44) der Platte (20) und einem Widerlager (46) erstrecken, das von dem Zapfen (34) ausgeht.To normally a relative movement between the frog tip (10) and Excluding plate (20), the centerpiece tip (10) is continuously subjected to a force in the direction of the driver device (18), which in the exemplary embodiment is caused by disc springs (40), (42) which are located between the underside (44) of the plate ( 20) and an abutment (46) extending from the pin (34).
Beim Durchfahren eines Schienenfahrzeuges liegt die entsprechende Flügelschiene (12) oder (14) auf der Oberseite (28) der Platte (20) auf, die derart zu der Herzstückspitze (10) gedrückt ist, daß man gleichfalls von einem Anliegen der Herzstückspitze (10) auf der Oberseite (28) sprechen kann.When driving through a rail vehicle, the corresponding wing rail (12) or (14) rests on the upper side (28) of the plate (20), which is pressed towards the frog tip (10) in such a way that the frog tip (10) can speak on the top (28).
Durch diese Maßnahmen ist beim Durchfahren eines Schienenfahrzeuges eine Relativbewegung zwischen den durchfahrenen Schienenabschnitten ausgeschlossen. Hierdurch wiederum ist sichergestellt, daß stets gleiche Überlaufbereiche bzw.- bedingungen für die Räder eines Schienenfahrzeuges vorliegen.These measures preclude a relative movement between the rail sections when the rail vehicle is being driven through. This in turn ensures that the same overflow areas or conditions are always present for the wheels of a rail vehicle.
Da beim Verstellen der Herzstückspitze (10) die Mitnehrmereinrichtung (18) mitbewegt werden muß, sollte sichergestellt werden, daß eine die Verstellung behindernde Haftreibung zwischen den Flügelschienen (12) und (14), d.h. deren Füßen (30) und (32) und der Oberseite (28) der Platte (44) reduziert bzw. vermieden wird.Since the driver device (18) must also be moved when the frog tip (10) is adjusted, it should be ensured that static friction between the wing rails (12) and (14), i.e. the feet (30) and (32) and the top (28) of the plate (44) is reduced or avoided.
Erfindungsgemäß ist hierzu vorgesehen, daß an der Mitnehmereinrichtung (18) z. B. eine Zylinder-Kolben-Anordnung (46), (48) abgestützt ist, deren Kolben (48) mit dem Zapfen (34) der Herzstückspitze (10) verbunden ist. Der Zylinder (46) kann z.B. an der Mitnehmereinrichtung (18), und zwar im Ausführungsbeispiel an den Schenkeln (22), (24) bzw. der Bodenplatte (26) befestigt sein. Wirkt nun auf den Kolben (48) in Richtung des Pfeils (50) ein Fluid, so wird die von den Tellerfedern (40) hervorgerufene Vorspannkraft überwunden, so daß sich die Mitnehmereinrichtung (18) relativ zu der Herzstückspitze (10) verschieben läßt, da diese selbst vor und hinter der Mitnehmereinrichtung (18) auf Gleitstühlen aufliegt. Durch das Herabziehen der Mitnehmereinrichtung (18) werden die Füße (30) und (32) der Flügelschienen (12) und (14) frei, so daß ein problemloses Verstellen der Herzstückspitze (10) erfolgen kann.According to the invention it is provided that on the driver device (18) z. B. a cylinder-piston arrangement (46), (48) is supported, the piston (48) with the pin (34) of the frog tip (10) is connected. The cylinder (46) can, for example, be attached to the driver device (18), specifically in the exemplary embodiment on the legs (22), (24) or the base plate (26). If a fluid now acts on the piston (48) in the direction of the arrow (50), the prestressing force caused by the plate springs (40) is overcome, so that the driver device (18) can be moved relative to the frog tip (10) because this lies in front of and behind the driver device (18) on sliding chairs. By pulling down the driver device (18), the feet (30) and (32) of the wing rails (12) and (14) are free, so that the tip of the frog (10) can be easily adjusted.
Die Anzahl der Mitnehmereinrichtungen (18) in einem Weichen- bzw. Kreuzungsbereich hängt von deren Auslegung und Anforderungen ab. So können entsprechende Mitnehmereinrichtungen (18) stets zwischen aufeinanderfolgende Gleitstühle bzw. Befestigungsplatten vorgesehen sein. Alternativ besteht die Möglichkeit, in größerem Abstand entsprechende Mitnehmereinrichtungen anzuordnen, also nicht jedem Gleitstuhl bzw. jeder Befestigungsplatte eine solche zuzuordnen. Auch kann nur eine Mitnehmereinrichtung (18) unmittelbar im Übergangsbereich vorgesehen sein.The number of driver devices (18) in a switch or crossing area depends on their design and requirements. Corresponding driver devices (18) can thus always be provided between successive sliding chairs or fastening plates. Alternatively, there is the possibility of arranging corresponding driver devices at a greater distance, that is to say not assigning such to each sliding chair or each mounting plate. Also, only one driver device (18) can be provided directly in the transition area.
Allgemein wird erfindungsgemäß ein Herzstück für Weichen oder Kreuzungen mit zwischen Flügelschienen (12, 14) angeordneter Herzstückspitze (10), insbesondere beweglicher wie federbeweglicher Herzstückspitze, vorgeschlagen, wobei die Flügelschienen im wesentlichen stationär auf Befestigungsplatten wie z.B. Rippenplatten befestigt sind. Um beim Durchfahren eines Schienenfahrzeuges eine Relativbewegung in vertikaler Richtung zu vermeiden, geht von der Herstückspitze eine Mitnehmereinrichtung aus, auf der die befahrene Flügelschiene aufliegt.According to the invention, a centerpiece for switches or crossings with a centerpiece tip (10) arranged between wing rails (12, 14), in particular a movable and spring-movable centerpiece tip, is generally proposed, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are attached.
