Definitions
- the invention relates to a switch device of the flat bed type for a switch system, with a base plate, a stock rail, a side rail and a sliding plate provided between the stock rail and the side rail for the switch of a switch rail, and a method for producing a switch device.
- a tongue device of the type mentioned has been known from practice for a long time.
- a special rail profile for example the special rail profile 75C1, whose old designation is BA75, is regularly used for the stock rail.
- the special rail profile is processed to create the stock rail.
- the leg of the groove is removed in the central area of the rail profile.
- the sliding plate rests on one side on a shoulder of the auxiliary rail, while on the opposite side it rests on a shoulder on the rail web of the stock rail.
- the known switch device is manufactured in such a way that first the stock rail with the sliding plate and the auxiliary rail are assembled using templates provided for this purpose. Then the welding takes place.
- the known tongue device has a number of disadvantages.
- the special rail profile required for the stock rail is comparatively expensive.
- the special rail profile is only produced in one quality. If a different quality is required for specific applications, the well-known special rail profile cannot ultimately be used. As a rule, a stock rail is then made from a solid block of appropriate quality, which is also relatively expensive.
- a switching device of the type mentioned in the opening paragraph in which a sliding plate is provided which extends at least over a substantial part of the length of the switching device, is a so-called flatbed switching device or a switching device of the flatbed type Tongue rail used, for example of the tongue profile type Fz 36.
- the continuous sliding plate is supported on a projection of the special rail profile of the stock rail on one side and on a corresponding projection of the auxiliary rail.
- the width of the switch device ie the space between the stock rail and the auxiliary rail, is comparatively small.
- the gap from the sliding plate to the top of the tongue assembly is "flat", hence the name "flat bed”.
- a switch device of the "deep bed” type differs from the flat bed type switch device.
- a machined standard rail is generally used as the stock rail.
- a larger and, in particular, higher tongue profile is used in the deep-bed switch mechanism, for example the 49E1A1 tongue profile.
- the switch does not lie on a sliding plate, but rather on individual sliding blocks or blocks spaced apart from one another. The distance from the top of the slide chairs to the top of the switch device is significantly lower than that of the flatbed switch device.
- the object of the present invention is to provide a switch device, in particular of the flat-bed type, that is to say with a sliding plate, which is simple and inexpensive to produce.
- the invention is based on a prior art flatbed switch device, which is characterized by a continuous sliding plate, in which the sliding plate rests on the side rail and on a projection of the special profile stock rail.
- the implementation of the support blocks according to the invention provides a support option for the sliding plate, so that it is no longer necessary to support the sliding plate on the stock rail.
- a support on the side rail can also be dispensed with.
- a special rail profile is not required to manufacture the stock rail. Although such a profile can be used become.
- the sliding plate is supported according to a different principle.
- a very important advantage resulting from the invention is that the stock rail can be produced from a standard rail profile by machining. If the switch device is a grooved rail switch device, a standard grooved rail profile, in particular type 60R2, can be used. Such a standard rail profile is not only significantly cheaper than a special rail profile, it can also - unlike the special rail profile - be obtained in any quality.
- the switch device In connection with the switch device according to the invention, it has been found that it makes sense to provide a plurality of support blocks distributed over the length of the switch device.
- the exact number ultimately depends on the length of the tongue device.
- the number of support blocks is between 5 and 12 per switch device.
- the support blocks are usually equally spaced. Exceptions only arise if a different arrangement is to be chosen for structural reasons. This is the case, for example, when the sliding plate has to be divided, as is the case, for example, in the area of the drive of the tongue tip of the tongue rail.
- the individual support blocks are relatively easy to assemble.
- the support blocks extend at least substantially perpendicularly away from the auxiliary rail in the direction of the stock rail. Due to the changing distance between the auxiliary rail and the stock rail, the individual support blocks can have different dimensions. For example, cube-like shapes are also provided, as well as cuboid configurations. Viewed from above, the individual support blocks usually have a square to trapezoidal shape. The trapezoidal shape is due to the curved course of the stock rail relative to the auxiliary rail.
- a through opening is provided between two adjacent support blocks.
- a corresponding passage opening should be provided between all the support blocks.
- This through-opening which preferably has a triangular or trapezoidal opening area when viewed from above, should preferably be designed in such a way that it runs at least essentially parallel to the respective component with its edge areas each facing a component. Furthermore, the majority of the area between two support blocks and the associated area between the auxiliary rail and the stock rail should be filled with the through opening. The reason for this is that the through-opening enables the areas of the aforementioned components, and in particular the stock rail, that face the through-opening to be welded very well. This is discussed in more detail below in connection with the production process.
- each of the support blocks provided is welded at the respective end faces on one side to the auxiliary rail and on the other side to the stock rail.
- the support block is attached exclusively via a welded connection.
- the support block is also screwed to the stock rail and otherwise welded. This is also discussed in more detail in connection with the manufacturing process.
- At least one screw opening which can preferably have a thread, is preferably provided on the end face of the support block facing the stock rail.
- at least one through-opening is preferably provided in the rail web of the stock rail, which enables screwing to the stock rail.
- this can also be a slot opening in order to compensate for any play that may have occurred.
- the aforementioned screw connection serves in particular to precisely maintain the expansion dimensions of the tongue device according to the invention.
- at least one filler piece is provided for arrangement between the end face on the stock rail side and the stock rail.
- the stock rail foot preferably has at least one recess in the area of one of the associated support blocks, which can extend to the rail web.
- the recess makes it possible to place the stock rail as a whole on the base plate and to push it up to the respective end faces of the support blocks. The stock rail is then screwed to the support blocks as described above.
- a heating device to be provided on the auxiliary rail.
- the heating device which is assigned a control device, if necessary with a temperature sensor, can ensure proper functioning of the tongue device according to the invention, especially in winter.
- the heating device which is preferably integrated into the auxiliary rail, can ensure that icing of the switch device, which can lead to blocking of the switch rail of the switch device, is avoided.
- the heating device assigned to the auxiliary rail can generate such thermal energy that the tongue rail is prevented from freezing to the sliding plate.
- the assignment of the heating device to the auxiliary rail makes sense here, since the auxiliary rail preferably forms the support for the sliding plate, so that thermal energy emitted by the heating device is transferred from the auxiliary rail to the sliding plate by thermal conduction.
- the heating device it is possible for the heating device to be controlled manually via appropriate switches.
- a sensor device that is assigned to the heating device in addition to or as an alternative to the manual control of the heating device.
- the sensor device preferably has at least one temperature sensor, which is used to measure the outside temperature and/or the temperature on the switch device, in particular on the sliding bed and/or the switch rail. If the temperature falls below a predetermined value, the heating device is put into operation or switched on. If, on the other hand, an upper limit temperature is reached, the heating device can be shut down or switched off, so that the energy consumption of the heating device can be kept as low as possible.
- the heating device is preferably designed as an electric heater, as a gas heater or as a geothermal heater. With a heating device designed in this way, reliable heating of the tongue device can be guaranteed as a result.
- the heating device has at least one heating pipe running along the auxiliary rail.
- the corresponding heating medium can then be guided in this heating tube.
- a corresponding resistance ladder is provided in the case of an electrical heater.
- the heating tube is preferably made of steel, in particular stainless steel.
- the heating tube preferably extends over the entire length of the auxiliary rail, but in particular at least over the length of the sliding plate. This ensures that the auxiliary rail and thus also the sliding plate is/are heated not only partially, but over their entire length.
- a recess extending along the side rail is provided in the side rail, in which the heating tube is accommodated.
- the depth of the recess is greater than or equal to the diameter of the heating tube.
- the cross section of the recess is at least partially adapted to the shape of the heating tube, so that the heating tube arranged in the recess bears flat against the auxiliary rail at least partially. It is particularly preferred in this context if the recess is U-shaped at its bottom or base, with the diameter of the bottom or base corresponding at least essentially to the diameter of the heating pipe. Ultimately, this results in a comparatively large contact surface between the heating pipe and the auxiliary rail, which promotes the transfer of heat from the heating pipe to the auxiliary rail.
- the recess in the auxiliary rail is provided on the underside and/or on the side of the auxiliary rail facing the stock rail. This configuration ensures that the heating pipe is arranged between the auxiliary rail or at least one leg of the auxiliary rail and the stock rail.
- the heating device is not accessible from the outside, so that there is no risk of the heating pipe being damaged by external influences.
- a preferred embodiment of the invention also provides for the heating tube to rest on the base plate at least in certain areas.
- the heating device can thus be used not only to deliver thermal energy to the auxiliary rail, but also to the base plate.
- the heat energy given off to the base plate can also be transferred to the slide plate by heat conduction via the stock rail.
- the heating tube is part of the assembly formed by the base plate, the support blocks of the auxiliary rail and the sliding plate. In this case, if support blocks are provided, the heating tube is arranged between the respective support blocks and the auxiliary rail.
- the heating tube bears against the support blocks at least in some areas.
- a part of the thermal energy of the heating device is then thermally conducted via the support blocks to the sliding plate, since the sliding plate ultimately rests not only on the auxiliary rail but also on the supporting blocks.
- Process engineering is in the method according to the invention for the production of the tongue device provided according to claim 1 to provide the sliding plate between the stock rail and the auxiliary rail, wherein between the stock rail and the auxiliary rail the plurality of support blocks resting on the base plate and separate from the stock rail and the auxiliary rail are provided, the sliding plate extending over the plurality of support blocks extends and rests on the plurality of support blocks, the base plate, the support blocks, the auxiliary rail and the sliding plate being first welded together to form an assembly.
- the invention also relates to an assembly of the aforementioned type for a tongue device.
- the assembly according to the invention differs from the prior art in particular in that the assembly lacks a stock rail.
- the assembly is an independent intermediate product that only becomes a point device after the stock rail is attached to the assembly.
- This way of producing an assembly differs significantly from the known production of the switch device, in which, as described above, first the stock rail with the sliding plate and the auxiliary rail are welded together after assembly using appropriate templates, which usually causes distortion. In the case of the invention, the welding also causes a delay.
- the welding group as an assembly has only one system-relevant component, namely the sliding plate. However, this can be straightened relatively easily on a press after it has cooled, so that the required evenness of the sliding plate can be restored.
- the stock rail is preferably produced from a standard rail profile by machining.
- the cost savings resulting from this and the possibility of being able to use different grades and shapes have already been described at the outset.
- the stock rail is preferably welded to the base plate of the assembly after the aforementioned assembly has been produced and the sliding plate has been adjusted if necessary.
- the welding preferably takes place in the prestressed state of the stock rail. Since in this case no templates are required for assembly, such prestressing can be carried out without further ado.
- the stock rail is screwed to the individual support blocks provided. In order to maintain the necessary spread of the switch device, one or more filler pieces are inserted between the end face of the respective support block on the stock rail side and the stock rail or the rail web of the stock rail. After the stock rail has been precisely aligned relative to the auxiliary rail, the stock rail is then welded to the base plate, as mentioned above. The welding is thus preferably carried out in the state screwed to the support blocks.
- the aforementioned through-openings between the individual support blocks play an important role.
- the interior area of the individual components in particular the interior area of the stock rail, is accessible via the passage openings. Because of this access, the stock rail can be securely welded to the base plate on its side facing the auxiliary rail.
- the switch device according to the invention results in a construction that ensures a significantly improved flatness of the sliding plate with very exact compliance with the spread dimensions between stock rail and auxiliary rail.
- a very cost-effective construction results, since expensive special profiles are not required.
- the switch device 1 is a grooved rail switch device that is provided for a switch system.
- the switch device 1 has a base plate 2 , a stock rail 3 , an auxiliary rail 4 and a slide plate 5 provided between the stock rail 3 and the auxiliary rail 4 .
- the present switch device 1 includes a switch rail 6, the switch 7 of which rests on the sliding plate 5 on the upper side.
- a plurality of support blocks 8 are arranged between the stock rail 3 and the auxiliary rail 4, on which the sliding plate 5 rests.
- the support blocks 8 are designed as separate support blocks from the stock rail 3 and the auxiliary rail 4 .
- the sliding plate 5 is only supported on the bearing blocks Bund of the side rail 4 (cf. 11 and 12 ). So there is an exclusive storage or arrangement of the sliding plate 5 on the support blocks 8 and the side rail 4 instead. There is no support on the stock rail 3
- the upper side 9 of the base plate 2 is flat and that the height of the bearing blocks 8 resting on the base plate 2 is also constant, so that the sliding plate 5 laid on the bearing blocks 8 runs parallel to the upper side 9 of the base plate 2 .
- the bearing blocks 8 and the sliding plate 5 extend in height over more than half the height of the stock rail 3 and the auxiliary rail 4, respectively, which is a characteristic of the point device of the flat bed type.
- the distance from the top of the stock rail or from the top of the stock rail to the top of the sliding plate 5 is less than half the height of the stock rail 3.
- the stock rail 3 is a standard rail profile of a standard grooved rail.
- the shape of the stock rail was produced by machining the standard rail profile. Since any standard rail profile can be used, the stock rail 3 can have any offered shape and quality. The use of a special rail profile, such as the 75C1 profile, is not necessary with switch device 1.
- the remaining components of the switch device 1 according to the invention in particular the base plate 2, the auxiliary rail 4 and also the switch rail 6 and the support blocks 8 can be made of known rail construction materials, in particular of structural steel.

- eight support blocks 8 are provided.
- Support blocks 8 shown in the right-hand area of the side rail 4 are at least essentially equally spaced. Only the three support blocks 8 shown on the left in the illustrated embodiment have a different spacing.
- This deviating distance results from the fact that the sliding plate 5 is divided in two in the area of an opening 10 in the side rail 4 . Due to the fact that the sliding plate 5 consists of several parts, a corresponding support via at least two support blocks 8 is required for each area of the sliding plate 5 .

The special rail profile is processed to create the stock rail. In particular, the leg of the groove is removed in the central area of the rail profile. In the known switch device, the sliding plate rests on one side on a shoulder of the auxiliary rail, while on the opposite side it rests on a shoulder on the rail web of the stock rail.
Die Herstellung der bekannten Zungenvorrichtung erfolgt derart, dass zunächst die Backenschiene mit der Gleitplatte und der Beischiene mit dafür vorgesehenen Schablonen zusammengefügt werden. Anschließend erfolgt die Verschweißung.The known switch device is manufactured in such a way that first the stock rail with the sliding plate and the auxiliary rail are assembled using templates provided for this purpose. Then the welding takes place.
Die bekannte Zungenvorrichtung hat eine Reihe von Nachteilen. Zum einen ist das für die Backenschiene notwendige Sonderschienenprofil vergleichsweise teuer. Darüber hinaus wird das Sonderschienenprofil nur in einer Güte hergestellt Sofern für bestimmte Anwendungszwecke eine andere Güte erforderlich ist, kann letztlich auf das bekannte Sonderschienenprofil nicht zurückgegriffen werden. In der Regel wird dann eine Backenschiene aus einem Vollblock entsprechender Güte hergestellt, was ebenfalls relativ aufwendig ist.The known tongue device has a number of disadvantages. On the one hand, the special rail profile required for the stock rail is comparatively expensive. In addition, the special rail profile is only produced in one quality. If a different quality is required for specific applications, the well-known special rail profile cannot ultimately be used. As a rule, a stock rail is then made from a solid block of appropriate quality, which is also relatively expensive.
Darüber hinaus hat es sich gezeigt, dass die Herstellung der bekannten Zungenvorrichtung verschiedene Nachteile mit sich bringt. Durch das Schweißen kommt es regelmäßig zum Verzug der systemrelevanten Bauteile Backenschiene, Gleitplatte und Beischiene. Diese Bauteile müssen nach dem Schweißen mit erheblichem Aufwand wieder gerichtet werden, um die notwendige Ebenheit der Zungenvorrichtung zu gewährleisten.In addition, it has been shown that the production of the known switch device entails various disadvantages. Welding regularly leads to distortion of the system-relevant components stock rail, sliding plate and auxiliary rail. After welding, these components have to be straightened again with considerable effort in order to ensure the necessary flatness of the tongue device.
Eine Zungenvorrichtung der eingangs genannten Art, bei der eine Gleitplatte vorgesehen ist, die sich zumindest über einen wesentlichen Teil der Länge der Zungenvorrichtung erstreckt, stellt eine sogenannte Flachbett-Zungenvorrichtung bzw. eine Zungenvorrichtung der Bauart Flachbett dar. Bei einer derartigen Zungenvorrichtung wird eine vergleichsweise kleine Zungenschiene verwendet, beispielsweise vom Zungenprofiltyp Fz 36. Die durchgehende Gleitplatte stützt sich auf einem Vorsprung des Sonderschienenprofils der Backenschiene auf der einen Seite und auf einem entsprechenden Vorsprung der Beischiene ab. Insgesamt ist die Breite der Zungenvorrichtung, das heißt der Zwischenraum zwischen der Backenschiene und der Beischiene vergleichsweise gering. Der Zwischenraum von der Gleitplatte zur Oberseite der Zungenvorrichtung ist "flach", woraus sich der Name "Flachbett" ergibt.A switching device of the type mentioned in the opening paragraph, in which a sliding plate is provided which extends at least over a substantial part of the length of the switching device, is a so-called flatbed switching device or a switching device of the flatbed type Tongue rail used, for example of the tongue profile type Fz 36. The continuous sliding plate is supported on a projection of the special rail profile of the stock rail on one side and on a corresponding projection of the auxiliary rail. Overall, the width of the switch device, ie the space between the stock rail and the auxiliary rail, is comparatively small. The gap from the sliding plate to the top of the tongue assembly is "flat", hence the name "flat bed".
Von Zungenvorrichtung der Bauart Flachbett unterscheidet sich eine Zungenvorrichtung der Bauart "Tiefbett". Bei einer Tiefbett-Zungenvorrichtung wird in der Regel als Backenschiene eine bearbeitete Regelschiene verwendet. Anders als bei einer Flachbett-Zungenvorrichtung wird bei der Tiefbett-Zungenvorrichtung ein größeres und insbesondere höheres Zungenprofil verwendet, beispielsweise das Zungenprofil 49E1A1. Die Zunge liegt bei der Tiefbett-Zungenvorrichtung nicht auf einer Gleitplatte auf, sondern auf einzelnen, voneinander beabstandeten Gleitklötzen oder -stühlen. Der Abstand der Oberseite der Gleitstühle zur Oberseite der Zungenvorrichtung ist deutlich tiefer als bei der Flachbett-Zungenvorrichtung.A switch device of the "deep bed" type differs from the flat bed type switch device. In the case of a low-bed switch device, a machined standard rail is generally used as the stock rail. In contrast to a flat-bed switch mechanism, a larger and, in particular, higher tongue profile is used in the deep-bed switch mechanism, for example the 49E1A1 tongue profile. In the case of the low-bed switch device, the switch does not lie on a sliding plate, but rather on individual sliding blocks or blocks spaced apart from one another. The distance from the top of the slide chairs to the top of the switch device is significantly lower than that of the flatbed switch device.

Aufgabe der vorliegenden Erfindung ist es, eine Zungenvorrichtung, insbesondere des Typs der Bauart Flachbett, also mit einer Gleitplatte zur Verfügung zu stellen, die einfach und kostengünstig herstellbar ist.The object of the present invention is to provide a switch device, in particular of the flat-bed type, that is to say with a sliding plate, which is simple and inexpensive to produce.
Bei der erfindungsgemäßen Zungenvorrichtung der eingangs genannten Art ist nun vorgesehen, dass zwischen der Backenschiene und der Beischiene eine Mehrzahl von auf der Grundplatte aufliegender, von der Backenschiene und der Beischiene separater Auflageklötze vorgesehen sind, wobei sich die Grundplatte über die Mehrzahl der Auflageklötze erstreckt und auf diesen aufliegt.In the switch device according to the invention of the type mentioned at the outset, it is now provided that between the stock rail and the auxiliary rail, a plurality of support blocks resting on the base plate and separate from the stock rail and the auxiliary rail are provided, with the base plate extending over the plurality of support blocks and onto this rests.
Erfindungsgemäß wird von einem anderen Prinzip der Auflage bzw. Abstützung der Gleitplatte als beim Stand der Technik Gebrauch gemacht. Bei der Erfindung wird von einer aus dem Stand der Technik bekannten Flachbett-Zungenvorrichtung, die sich durch eine durchgehende Gleitplatte auszeichnet, ausgegangen, bei der die Gleitplatte zum einen auf der Beischiene und zum anderen auf einem Vorsprung der Sonderprofil-Backenschiene aufliegt. Durch die Realisierung der erfindungsgemäßen Auflageklötze wird eine Abstützmöglichkeit für die Gleitplatte zur Verfügung gestellt, so dass eine Abstützung der Gleitplatte an der Backenschiene nicht mehr erforderlich ist. Auch kann grundsätzlich auf eine Abstützung an der Beischiene verzichtet werden. Allerdings kann es sich für relativ schmale Ausführungsformen der Zungenvorrichtung anbieten, die Abstützung auch noch an der Beischiene zu realisieren, so dass dann eine gemeinsame Abstützung der Gleitplatte über die Auflageklötze und an einer korrespondierenden Stufe der Beischiene erfolgt. Hieraus resultiert, dass ein Sonderschienenprofil zur Herstellung der Backenschiene nicht erforderlich ist. Zwar kann ein solches Profil eingesetzt werden. Dennoch erfolgt die Abstützung der Gleitplatte bei der erfindungsgemäßen Zungenvorrichtung nach einem anderen Prinzip.According to the invention, use is made of a different principle of the bearing or support of the sliding plate than in the prior art. The invention is based on a prior art flatbed switch device, which is characterized by a continuous sliding plate, in which the sliding plate rests on the side rail and on a projection of the special profile stock rail. The implementation of the support blocks according to the invention provides a support option for the sliding plate, so that it is no longer necessary to support the sliding plate on the stock rail. In principle, a support on the side rail can also be dispensed with. However, for relatively narrow embodiments of the switch device, it may be advisable to implement the support on the auxiliary rail as well, so that the sliding plate is then jointly supported via the support blocks and on a corresponding step of the auxiliary rail. The result of this is that a special rail profile is not required to manufacture the stock rail. Although such a profile can be used become. Nevertheless, in the switch device according to the invention, the sliding plate is supported according to a different principle.
Ein ganz wesentlicher Vorteil, der sich durch die Erfindung ergibt, liegt darin, dass die Backenschiene aus einem Regelschienenprofil durch abtragende Bearbeitung hergestellt sein kann. Handelt es sich bei der Zungenvorrichtung um eine Rillenschienen-Zungenvorrichtung, kann auf ein Regelrillenschienenprofil, insbesondere des Typs 60R2, zurückgegriffen werden. Ein derartiges Regelschienenprofil ist nicht nur deutlich günstiger als ein Sonderschienenprofil, es kann auch - anders als das Sonderschienenprofil - in jeglicher Güte bezogen werden.A very important advantage resulting from the invention is that the stock rail can be produced from a standard rail profile by machining. If the switch device is a grooved rail switch device, a standard grooved rail profile, in particular type 60R2, can be used. Such a standard rail profile is not only significantly cheaper than a special rail profile, it can also - unlike the special rail profile - be obtained in any quality.
Im Zusammenhang mit der erfindungsgemäßen Zungenvorrichtung ist festgestellt worden, dass es sich anbietet, über die Länge der Zungenvorrichtung verteilt eine Mehrzahl von Auflageklötzen vorzusehen. Die genaue Anzahl ist letztlich abhängig von der Länge der Zungenvorrichtung. In der Regel liegt die Anzahl der Auflageklötze zwischen 5 und 12 pro Zungenvorrichtung. Dabei sind die Auflageklötze in der Regel gleich beabstandet. Ausnahmen ergeben sich nur dann, wenn aufgrund baulicher Gründe eine andere Anordnung zu wählen ist. Dies ist beispielsweise dann der Fall, wenn die Gleitplatte geteilt werden muss, wie dies beispielsweise im Bereich des Antriebs der Zungenspitze der Zungenschiene der Fall ist.In connection with the switch device according to the invention, it has been found that it makes sense to provide a plurality of support blocks distributed over the length of the switch device. The exact number ultimately depends on the length of the tongue device. As a rule, the number of support blocks is between 5 and 12 per switch device. The support blocks are usually equally spaced. Exceptions only arise if a different arrangement is to be chosen for structural reasons. This is the case, for example, when the sliding plate has to be divided, as is the case, for example, in the area of the drive of the tongue tip of the tongue rail.
Die einzelnen Auflageklötze lassen sich relativ leicht montieren. Bei einer üblichen Bauart der Zungenvorrichtung erstrecken sich die Auflageklötze zumindest im wesentlichen senkrecht von der Beischiene weg in Richtung zur Backenschiene. Aufgrund des sich ändernden Abstandes der Beischiene von der Backenschiene können die einzelnen Auflageklötze unterschiedliche Abmaße haben. So sind beispielsweise würfelartige Formen ebenso vorgesehen, wie quaderförmige Ausgestaltungen. In Draufsicht gesehen haben die einzelnen Auflageklötze dabei in der Regel eine quadratische bis trapezförmige Form. Die Trapezform ergibt sich aufgrund des bogenförmigen Verlaufs der Backenschiene relativ zur Beischiene.The individual support blocks are relatively easy to assemble. In a conventional construction of the switch device, the support blocks extend at least substantially perpendicularly away from the auxiliary rail in the direction of the stock rail. Due to the changing distance between the auxiliary rail and the stock rail, the individual support blocks can have different dimensions. For example, cube-like shapes are also provided, as well as cuboid configurations. Viewed from above, the individual support blocks usually have a square to trapezoidal shape. The trapezoidal shape is due to the curved course of the stock rail relative to the auxiliary rail.
Bei einer bevorzugten Ausgestaltung der Erfindung ist zwischen zwei benachbarten Auflageklötzen eine Durchgangsöffnung vorgesehen. Grundsätzlich sollte zwischen allen Auflageklötzen jeweils eine entsprechende Durchgangsöffnung vorgesehen sein. Diese Durchgangsöffnung, die bevorzugt einen in Draufsicht dreieckigen oder trapezförmigen Öffnungsbereich hat, sollte bevorzugt so ausgebildet sein, dass sie mit ihren jeweils einem Bauteil zugewandten Randbereichen zumindest im wesentlichen parallel zu dem jeweiligen Bauteil verläuft. Im übrigen sollte der überwiegende Bereich zwischen zwei Auflageklötzen und dem zugehörigen Bereich zwischen der Beischiene und der Backenschiene von der Durchgangsöffnung ausgefüllt sein. Hintergrund ist, dass die Durchgangsöffnung sehr gut eine Verschweißung der der Durchgangsöffnung zugewandten Bereiche der vorgenannten Bauteile, und insbesondere der Backenschiene, ermöglicht. Hierauf wird nachfolgend im Zusammenhang mit dem Herstellungsverfahren noch näher eingegangen.In a preferred embodiment of the invention, a through opening is provided between two adjacent support blocks. In principle, a corresponding passage opening should be provided between all the support blocks. This through-opening, which preferably has a triangular or trapezoidal opening area when viewed from above, should preferably be designed in such a way that it runs at least essentially parallel to the respective component with its edge areas each facing a component. Furthermore, the majority of the area between two support blocks and the associated area between the auxiliary rail and the stock rail should be filled with the through opening. The reason for this is that the through-opening enables the areas of the aforementioned components, and in particular the stock rail, that face the through-opening to be welded very well. This is discussed in more detail below in connection with the production process.
Bei der erfindungsgemäßen Ausgestaltung wird insbesondere jeder der vorgesehenen Auflageklötze an den jeweiligen Stirnseiten an der einen Seite mit der Beischiene und an der anderen Seite mit der Backenschiene verschweißt. Allerdings bestehen dennoch Unterschiede zwischen den einzelnen Befestigungsbereichen. Im Bereich der Beischiene erfolgt die Befestigung des Auflageklotzes ausschließlich über eine Schweißverbindung. Demgegenüber ist es im Bereich der Backenschiene so, dass der Auflageklotz mit der Backenschiene auch verschraubt und im übrigen verschweißt ist. Hierauf wird ebenfalls näher im Zusammenhang mit dem Herstellungsverfahren eingegangen.In the embodiment according to the invention, in particular each of the support blocks provided is welded at the respective end faces on one side to the auxiliary rail and on the other side to the stock rail. However, there are still differences between the individual fastening areas. In the area of the auxiliary rail, the support block is attached exclusively via a welded connection. In contrast, in the area of the stock rail, the support block is also screwed to the stock rail and otherwise welded. This is also discussed in more detail in connection with the manufacturing process.
Jedenfalls ist, um eine Verschraubung des Auflageklotzes mit der Backenschiene zu ermöglichen, an der der Backenschiene zugewandten Stirnseite des Auflageklotzes vorzugsweise wenigstens eine Schrauböffnung, die bevorzugt ein Gewinde aufweisen kann, vorgesehen. Korrespondierend zu der Schrauböffnung ist im Schienensteg der Backenschiene bevorzugt wenigstens eine Durchgangsöffnung vorgesehen, welche die Verschraubung mit der Backenschiene ermöglicht.In any case, in order to enable the support block to be screwed to the stock rail, at least one screw opening, which can preferably have a thread, is preferably provided on the end face of the support block facing the stock rail. Corresponding to the screw opening, at least one through-opening is preferably provided in the rail web of the stock rail, which enables screwing to the stock rail.
Hierbei kann es sich grundsätzlich auch um eine Langlochöffnung handeln, um ein gegebenenfalls aufgetretenes Spiel auszugleichen.In principle, this can also be a slot opening in order to compensate for any play that may have occurred.
Letztlich dient die zuvor erwähnte Verschraubung insbesondere dazu, die Spreizmaße der erfindungsgemäßen Zungenvorrichtung präzise einzuhalten. Zu diesem Zweck ist insbesondere wenigstens ein Füllstück zur Anordnung zwischen der backenschienenseitigen Stirnseite und der Backenschiene vorgesehen. Durch Einsatz entsprechender Füllstücke, die auch eine unterschiedliche Breite haben können, ist es ohne weiteres möglich, die notwendigen Spreizmaße exakt einzuhalten.Ultimately, the aforementioned screw connection serves in particular to precisely maintain the expansion dimensions of the tongue device according to the invention. For this purpose, in particular at least one filler piece is provided for arrangement between the end face on the stock rail side and the stock rail. By using appropriate filler pieces, which can also have a different width, it is easily possible to precisely comply with the necessary spreading dimensions.
Um die Montage der Backenschiene bei der Herstellung der Zungenvorrichtung so einfach wie möglich zu gestalten, weist der Backenschienenfuß im Bereich eines der zugeordneten Auflageklötze vorzugsweise wenigstens eine Ausnehmung auf, die bis hin zum Schienensteg reichen kann. Durch die Ausnehmung ist es möglich, die Backenschiene insgesamt auf die Grundplatte aufzusetzen und bis an die jeweiligen Stirnseiten der Auflageklötze heranzuschieben. Anschließend erfolgt dann die zuvor beschriebene Verschraubung der Backenschiene mit den Auflageklötzen.In order to make the assembly of the stock rail as simple as possible during the manufacture of the switch device, the stock rail foot preferably has at least one recess in the area of one of the associated support blocks, which can extend to the rail web. The recess makes it possible to place the stock rail as a whole on the base plate and to push it up to the respective end faces of the support blocks. The stock rail is then screwed to the support blocks as described above.
Bei einer besonders bevorzugten Ausgestaltung der gattungsgemäßen Zungenvorrichtung, die mit aber auch ohne Auflageklötze realisiert sein kann, ist vorgesehen, dass an der Beischiene eine Heizeinrichtung vorgesehen ist. Diesem Aspekt kommt also auch eigenständige erfinderische Bedeutung zu. Die Heizeinrichtung, der bedarfsweise eine Steuereinrichtung, gegebenenfalls mit Temperatursensor, zugeordnet ist, kann die ordnungsgemäße Funktion der erfindungsgemäßen Zungenvorrichtung insbesondere im Winter sicherstellen. Durch die bevorzugt in die Beischiene integrierte Heizeinrichtung kann sichergestellt werden, dass ein Vereisen der Zungenvorrichtung, die zu einer Blockierung der Zungenschiene der Zungenvorrichtung führen kann, vermieden wird. Letztlich kann durch die Heizeinrichtung, die der Beischiene zugeordnet ist, eine solche Wärmeenergie erzeugt werden, dass ein Festfrieren der Zungenschiene an der Gleitplatte verhindert. Dabei bietet sich die Zuordnung der Heizeinrichtung zur Beischiene an, da die Beischiene bevorzugt die Auflage für die Gleitplatte bildet, so dass von der Heizeinrichtung abgegebene Wärmeenergie durch Wärmeleitung von der Beischiene auf die Gleitplatte übertragen wird.In a particularly preferred embodiment of the generic switch device, which can be implemented with or without support blocks, provision is made for a heating device to be provided on the auxiliary rail. This aspect is therefore also of independent inventive importance. The heating device, which is assigned a control device, if necessary with a temperature sensor, can ensure proper functioning of the tongue device according to the invention, especially in winter. The heating device, which is preferably integrated into the auxiliary rail, can ensure that icing of the switch device, which can lead to blocking of the switch rail of the switch device, is avoided. Ultimately, the heating device assigned to the auxiliary rail can generate such thermal energy that the tongue rail is prevented from freezing to the sliding plate. The assignment of the heating device to the auxiliary rail makes sense here, since the auxiliary rail preferably forms the support for the sliding plate, so that thermal energy emitted by the heating device is transferred from the auxiliary rail to the sliding plate by thermal conduction.
Grundsätzlich ist es möglich, dass die Heizeinrichtung über entsprechende Schalter manuell angesteuert wird. Bevorzugt ist es jedoch, zusätzlich oder alternativ zu der manuellen Ansteuerung der Heizeinrichtung eine Sensoreinrichtung vorzusehen, die der Heizeinrichtung zugeordnet ist. Die Sensoreinrichtung weist bevorzugt wenigstens einen Temperatursensor auf, über den die Außentemperatur und/oder die Temperatur an der Zungenvorrichtung, insbesondere am Gleitbett und/oder der Zungenschiene gemessen wird. Bei Unterschreiten einer vorgegebenen Temperatur wird dann die Heizeinrichtung in Betrieb genommen bzw. eingeschaltet. Ist hingegen eine obere Grenztemperatur erreicht, kann die Heizeinrichtung abgestellt bzw. ausgeschaltet werden, so dass der Energieverbrauch der Heizeinrichtung so gering wie möglich gehalten werden kann.In principle, it is possible for the heating device to be controlled manually via appropriate switches. However, it is preferred to provide a sensor device that is assigned to the heating device in addition to or as an alternative to the manual control of the heating device. The sensor device preferably has at least one temperature sensor, which is used to measure the outside temperature and/or the temperature on the switch device, in particular on the sliding bed and/or the switch rail. If the temperature falls below a predetermined value, the heating device is put into operation or switched on. If, on the other hand, an upper limit temperature is reached, the heating device can be shut down or switched off, so that the energy consumption of the heating device can be kept as low as possible.
Bevorzugt ist die Heizeinrichtung als elektrische Heizung, als Gasheizung oder als Geothermieheizung ausgeführt. Bei einer derart ausgeführten Heizeinrichtung kann ein sicheres Beheizen der Zungenvorrichtung im Ergebnis gewährleistet werden.The heating device is preferably designed as an electric heater, as a gas heater or as a geothermal heater. With a heating device designed in this way, reliable heating of the tongue device can be guaranteed as a result.
Bei einer bevorzugten Ausgestaltung weist die Heizeinrichtung wenigstens ein längs der Beischiene verlaufendes Heizrohr auf. In diesem Heizrohr kann dann das entsprechende Heizmedium geführt werden. Im Falle einer elektrischen Heizung ist ein entsprechender Widerstandsleiter vorgesehen. Im Hinblick auf die ausgesprochen robusten Anforderungen im Bahnbetrieb besteht das Heizrohr vorzugsweise aus Stahl, insbesondere aus Edelstahl.In a preferred embodiment, the heating device has at least one heating pipe running along the auxiliary rail. The corresponding heating medium can then be guided in this heating tube. In the case of an electrical heater, a corresponding resistance ladder is provided. With regard to the extremely robust requirements in railway operation, the heating tube is preferably made of steel, in particular stainless steel.
Um eine sichere Beheizung der relevanten Teile der Zungenvorrichtung gewährleisten zu können, erstreckt sich das Heizrohr bevorzugt über die gesamte Länge der Beischiene, insbesondere zumindest jedoch über die Länge der Gleitplatte. Hierdurch wird sichergestellt, dass die Beischiene und damit auch die Gleitplatte nicht nur partiell, sondern über ihre gesamte Länge beheizt wird/werden.In order to be able to ensure reliable heating of the relevant parts of the switch device, the heating tube preferably extends over the entire length of the auxiliary rail, but in particular at least over the length of the sliding plate. This ensures that the auxiliary rail and thus also the sliding plate is/are heated not only partially, but over their entire length.
Um einen guten Wärmeübergang vom Heizrohr auf die Beischiene zu erzielen und um im übrigen den Bauraum zwischen den weiteren Bauteilen der Zungenvorrichtung nicht zu beeinträchtigen, ist in der Beischiene eine sich längs der Beischiene erstreckende Ausnehmung vorgesehen, in der das Heizrohr aufgenommen ist. Bevorzugt ist in diesem Zusammenhang, dass die Tiefe der Ausnehmung größer oder gleich dem Durchmesser des Heizrohrs ist. Auf diese Weise kann letztlich eine vollständige Integration des Heizrohrs in die Beischiene sichergestellt werden. Das Heizrohr wird damit vollständig in der Ausnehmung aufgenommen.In order to achieve good heat transfer from the heating pipe to the side rail and otherwise not to impair the installation space between the other components of the tongue device, a recess extending along the side rail is provided in the side rail, in which the heating tube is accommodated. In this context, it is preferred that the depth of the recess is greater than or equal to the diameter of the heating tube. In this way, a complete integration of the heating pipe into the auxiliary rail can ultimately be ensured. The heating tube is thus completely accommodated in the recess.
Zur Erzielung eines hohen Wärmeübergangs ist die Ausnehmung im Querschnitt zumindest bereichsweise an die Form des Heizrohrs angepasst, so dass das in der Ausnehmung angeordnete Heizrohr zumindest bereichsweise flächig an der Beischiene anliegt. Ganz besonders bevorzugt ist es in diesem Zusammenhang, wenn die Ausnehmung an ihrem Boden bzw. Grund U-förmig ausgebildet ist, wobei der Durchmesser des Bodens bzw. Grundes zumindest im wesentlichen dem Durchmesser des Heizrohres entspricht. Letztlich ergibt sich auf diese Weise eine vergleichsweise große Kontaktfläche zwischen dem Heizrohr und der Beischiene, was den Wärmeübergang von dem Heizrohr auf die Beischiene begünstigt.In order to achieve high heat transfer, the cross section of the recess is at least partially adapted to the shape of the heating tube, so that the heating tube arranged in the recess bears flat against the auxiliary rail at least partially. It is particularly preferred in this context if the recess is U-shaped at its bottom or base, with the diameter of the bottom or base corresponding at least essentially to the diameter of the heating pipe. Ultimately, this results in a comparatively large contact surface between the heating pipe and the auxiliary rail, which promotes the transfer of heat from the heating pipe to the auxiliary rail.
Bei einer bevorzugten Ausgestaltung der Erfindung ist die Ausnehmung in der Beischiene an der Unterseite und/oder an der der Backenschiene zugewandten Seite der Beischiene vorgesehen. Durch diese Ausgestaltung ist sichergestellt, dass das Heizrohr zwischen der Beischiene oder zumindest einem Schenkel der Beischiene und der Backenschiene angeordnet ist. Von außen ist die Heizeinrichtung nicht zugänglich, so dass auch etwaige Beschädigungen des Heizrohres durch äußere Einflüsse nicht zu befürchten sind.In a preferred embodiment of the invention, the recess in the auxiliary rail is provided on the underside and/or on the side of the auxiliary rail facing the stock rail. This configuration ensures that the heating pipe is arranged between the auxiliary rail or at least one leg of the auxiliary rail and the stock rail. The heating device is not accessible from the outside, so that there is no risk of the heating pipe being damaged by external influences.
Zur Gewährleistung eines guten Wärmeübergangs ist bei einer bevorzugten Ausgestaltung der Erfindung im übrigen vorgesehen, dass das Heizrohr zumindest bereichsweise auf der Grundplatte aufliegt. Über die Heizeinrichtung kann damit nicht nur Wärmeenergie an die Beischiene, sondern auch an die Grundplatte abgegeben werden. Die an die Grundplatte abgegebene Wärmeenergie kann durch Wärmeleitung über die Backenschiene ebenfalls auf die Gleitplatte übertragen werden. Insbesondere wenn die erfindungsgemäße Heizeinrichtung in Kombination mit der eingangs beschriebenen Ausführungsform verwendet wird, ist es so, dass das Heizrohr Teil der Baugruppe, die von der Grundplatte, den Auflageklötzen der Beischiene und der Gleitplatte gebildet wird, ist. In diesem Falle ist, soweit Auflageklötze vorgesehen sind, das Heizrohr zwischen den jeweiligen Auflageklötzen und der Beischiene angeordnet.In order to ensure good heat transfer, a preferred embodiment of the invention also provides for the heating tube to rest on the base plate at least in certain areas. The heating device can thus be used not only to deliver thermal energy to the auxiliary rail, but also to the base plate. The heat energy given off to the base plate can also be transferred to the slide plate by heat conduction via the stock rail. In particular, when the heating device according to the invention is used in combination with the embodiment described above, the heating tube is part of the assembly formed by the base plate, the support blocks of the auxiliary rail and the sliding plate. In this case, if support blocks are provided, the heating tube is arranged between the respective support blocks and the auxiliary rail.
Von besonderem Vorteil ist es in diesem Zusammenhang, dass das Heizrohr zumindest bereichsweise an den Auflageklötzen anliegt. Auch hierbei ergibt sich dann eine Wärmeleitung eines Teils der Wärmeenergie der Heizeinrichtung über die Auflageklötze zur Gleitplatte, da die Gleitplatte letztlich nicht nur auf der Beischiene, sondern auch auf den Auflageklötzen aufliegt.It is of particular advantage in this connection that the heating tube bears against the support blocks at least in some areas. In this case, too, a part of the thermal energy of the heating device is then thermally conducted via the support blocks to the sliding plate, since the sliding plate ultimately rests not only on the auxiliary rail but also on the supporting blocks.
Verfahrenstechnisch ist bei dem erfindungsgemäßen Verfahren zur Herstellung der Zungenvorrichtung gemäß Anspruch 1 vorgesehen, die Gleitplatte zwischen der Backenschiene und der Beischiene vorzusehen, wobei zwischen der Backenschiene und der Beischiene die Mehrzahl von auf der Grundplatte aufliegenden, von der Backenschiene und der Beischiene separaten Auflageklötze vorgesehen werden, wobei sich die Gleitplatte über die Mehrzahl der Auflageklötze erstreckt und auf der Mehrzahl der Auflageklötze aufliegt, wobei zunächst die Grundplatte, die Auflageklötze, die Beischiene und die Gleitplatte miteinander zu einer Baugruppe verschweißt werden. Insofern bezieht sich die Erfindung auch auf eine Baugruppe der vorgenannten Art für eine Zungenvorrichtung. Die erfindungsgemäße Baugruppe unterscheidet sich vom Stand der Technik insbesondere dadurch, dass es bei der Baugruppe an einer Backenschiene fehlt. Bei der Baugruppe handelt es sich um ein selbständiges Zwischenerzeugnis, das erst nach Befestigen der Backenschiene an der Baugruppe zu einer Zungenvorrichtung wird. Diese Art der Herstellung einer Baugruppe unterscheidet sich erheblich von der bekannten Herstellung der Zungenvorrichtung, bei der, wie eingangs beschrieben, zunächst die Backenschiene mit der Gleitplatte und der Beischiene nach Zusammenfügen über entsprechende Schablonen miteinander verschweißt werden, wodurch in der Regel ein Verzug auftritt. Bei der Erfindung kommt es durch das Schweißen zwar auch zu einem Verzug. Hier besteht allerdings der Vorteil, dass die Schweißgruppe als Baugruppe nur ein systemrelevantes Bauteil hat, nämlich die Gleitplatte. Diese lässt sich aber relativ einfach nach dem Erkalten auf einer Presse richten, so dass die benötigte Ebenheit der Gleitplatte wiederhergestellt werden kann.Process engineering is in the method according to the invention for the production of the tongue device provided according to
Erfindungsgemäß wird die Backenschiene, vorzugsweise, aus einem Regelschienenprofil durch abtragende Bearbeitung hergestellt. Die sich hierdurch ergebende Kostenersparnis und die Möglichkeit, unterschiedliche Güten und Formen einsetzen zu können, sind eingangs bereits beschrieben worden.According to the invention, the stock rail is preferably produced from a standard rail profile by machining. The cost savings resulting from this and the possibility of being able to use different grades and shapes have already been described at the outset.
Bevorzugt wird die Backenschiene nach Herstellen der vorgenannten Baugruppe und bedarfsweise Richten der Gleitplatte mit der Grundplatte der Baugruppe verschweißt. Dabei erfolgt die Verschweißung vorzugsweise im vorgespannten Zustand der Backenschiene. Da hierbei keine Schablonen zum Zusammenfügen erforderlich sind, kann ein solches Vorspannen ohne weiteres erfolgen. Bevor die abschließende Verschweißung der Backenschiene mit der Grundplatte der Baugruppe erfolgt, wird die Backenschiene allerdings mit den einzelnen vorgesehenen Auflageklötzen verschraubt. Zur Einhaltung des notwendigen Spreizmaßes der Zungenvorrichtung werden dabei insbesondere ein oder mehrere Füllstücke zwischen die backenschienenseitige Stirnseite des jeweiligen Auflageklotzes und die Backenschiene bzw. den Schienensteg der Backenschiene eingefügt. Nach exakter Ausrichtung der Backenschiene relativ zur Beischiene erfolgt dann die zuvor erwähnte Verschweißung der Backenschiene mit der Grundplatte. Die Verschweißung erfolgt dabei also vorzugsweise in dem mit den Auflageklötzen verschraubten Zustand.The stock rail is preferably welded to the base plate of the assembly after the aforementioned assembly has been produced and the sliding plate has been adjusted if necessary. The welding preferably takes place in the prestressed state of the stock rail. Since in this case no templates are required for assembly, such prestressing can be carried out without further ado. However, before the stock rail is finally welded to the base plate of the assembly, the stock rail is screwed to the individual support blocks provided. In order to maintain the necessary spread of the switch device, one or more filler pieces are inserted between the end face of the respective support block on the stock rail side and the stock rail or the rail web of the stock rail. After the stock rail has been precisely aligned relative to the auxiliary rail, the stock rail is then welded to the base plate, as mentioned above. The welding is thus preferably carried out in the state screwed to the support blocks.
Aufgrund der besonderen Art der Herstellung durch Erstellung der zuvor genannten Baugruppe in einem ersten Schritt spielen die vorgenannten Durchgangsöffnungen zwischen den einzelnen Auflageklötzen eine wichtige Rolle. Über die Durchgangsöffnungen ist der innenliegende Bereich der einzelnen Bauteile, insbesondere der innenliegende Bereich der Backenschiene zugänglich. Aufgrund dieses Zugangs kann die Backenschiene an ihrer der Beischiene zugewandten Seite mit der Grundplatte sicher verschweißt werden.Due to the special type of production by creating the aforementioned assembly in a first step, the aforementioned through-openings between the individual support blocks play an important role. The interior area of the individual components, in particular the interior area of the stock rail, is accessible via the passage openings. Because of this access, the stock rail can be securely welded to the base plate on its side facing the auxiliary rail.
Im Ergebnis ergibt sich durch die erfindungsgemäße Zungenvorrichtung eine Konstruktion, die eine deutlich verbesserte Ebenheit der Gleitplatte bei sehr exakter Einhaltung der Spreizmaße zwischen Backenschiene und Beischiene gewährleistet. Darüber hinaus ergibt sich eine sehr kostengünstige Konstruktion, da teure Sonderprofile nicht erforderlich sind. Es besteht darüber hinaus eine erhebliche Flexibilität bezüglich der Güten und Formen der Backenschiene.As a result, the switch device according to the invention results in a construction that ensures a significantly improved flatness of the sliding plate with very exact compliance with the spread dimensions between stock rail and auxiliary rail. In addition, a very cost-effective construction results, since expensive special profiles are not required. There is also considerable flexibility with regard to the grades and shapes of the stock rail.

Korrespondierend zu den Schrauböffnungen 13 an den Auflageklötzen 8 ist im Schienensteg 14 der Backenschiene 3 eine entsprechende Anzahl von Durchgangsöffnungen 15 vorgesehen, durch die entsprechende Schrauben geschoben und mit der Schrauböffnung 13 verschraubt werden können.Corresponding to the
Nicht dargestellt sind Füllstücke zur Anordnung zwischen der backenschienenseitigen Stirnseite 12 und der Backenschiene 3 bzw. dem Schienensteg 14 der Backenschiene 3. Grundsätzlich bietet es sich an, wenn Füllstücke unterschiedlicher Stärke vorgesehen sind, so dass unterschiedliche Spaltmaße überbrückt werden können. Auch ist es möglich, an einer Befestigungsstelle eine Mehrzahl von Füllstücken vorzusehen. Zweckmäßigerweise sollten die Füllstücke ebenfalls eine Durchgangsöffnung aufweisen, so dass bei der Verschraubung der Backenschiene 3 mit den Auflageklötzen 8 die Füllstücke mitverschraubt und sicher an der Schraube gehalten werden.Not shown are filler pieces for the arrangement between the
Im einzelnen nicht dargestellt ist, dass der Backenschienenfuß 16 eine Mehrzahl von Ausnehmungen für die Auflageklötze 8 aufweist.

Nach der Erstellung der Baugruppe 19 wird die Baugruppe 19 vermessen. Aufgrund der Verschweißung kommt es regelmäßig zu einem Verzug der Gleitplatte 5. Wird ein solcher Verzug festgestellt, wird die Baugruppe 19 gerichtet. Im einzelnen wird nach Erkalten der Baugruppe 19 insbesondere die Gleitplatte 5 auf einer Presse gerichtet, um die notwendige Ebenheit bzw. Parallelität der Gleitplatte 5 zur Grundplatte 2 wiederherzustellen.After the
Anschließend oder auch vorher oder gleichzeitig mit der Herstellung der Baugruppe 19 wird die Backenschiene 3 aus einem Regelschienenprofil durch abtragende Bearbeitung hergestellt. Hierzu wird insbesondere im mittigen Bereich der Backenschiene 3 der Rillenschenkel entfernt. Gleichzeitig wird der Backenschienenfuß 16 eingeschnitten bzw. mit Ausnehmungen für die Auflageklötze 8 versehen, so dass es möglich ist, die Backenschiene 3 auf die Grundplatte 2 aufzusetzen und bis an die Auflageklötze 8 heranzuschieben. Nach entsprechender Ausrichtung der Backenschiene 3 kann diese dann mit den Auflageklötzen 8 verschraubt werden. Zur Einhaltung der notwendigen Spreizmaße werden zwischen die Stirnseite 12 und den Schienensteg 14 der Backenschiene 3 an den notwendigen Stellen Füllstücke eingesetzt.Subsequently or also before or at the same time as the

Hinzuweisen ist darauf, dass es grundsätzlich allerdings auch möglich ist, dass das Heizrohr 24 nicht unter einem Winkel zur Grundplatte 2 zugeführt wird, dass das Heizrohr 24 also über die gesamte Länge der Beischiene 4 parallel zur Grundplatte 2 verläuft.It should be noted that it is also fundamentally possible for the
Bei der dargestellten Ausführungsform ist die Ausnehmung 25 an der der Backenschiene 3 zugewandten Seite der Beischiene 4 an bzw. in der Beischiene 4 vorgesehen. Solange das Heizrohr 24 unter dem Winkel α zur Grundplatte 2 verläuft, befindet sich unterhalb des Heizrohres 24 und damit zwischen dem Heizrohr 24 und der Grundplatte 2 noch Material der Beischiene 4. Sobald das Heizrohr 24 parallel zur Grundplatte 2 verläuft, ist die Ausnehmung 25 auch an der Unterseite der Beischiene 4 vorgesehen. Hierbei ist es so, dass das Heizrohr 24 auf der Grundplatte 2 aufliegt, seitlich an der Beischiene 4 und am Auflageklotz 8 anliegt und oberseitig wiederum an der Beischiene 4 anliegt. Letztlich hat der durch die Ausnehmung 25 gebildete Aufnahmeraum von der Höhe und Breite etwa die Abmaße, die dem Durchmesser des Heizrohrs 24 entsprechen.In the illustrated embodiment, the
