Definitions
- the present invention relates to a device for adjusting a switch tongue according to the preamble of Patentaus jointlychs. 1
- railway turnouts are equipped with locking devices, as described, for example, in the European patent application EP 0 885 795 A1 are disclosed.
- This European patent application shows the function of a modern closure device (latch closure CKA). Shown there is the locking or unlocking and switching the switch tongues, which happens in a latch closure by means of a locking rod and a pawl.
- the switch blade connected to the closure pawl via a closure bearing switch blade is guided in the locking process by the locking rod against the associated floor rail, the pawl under the floor rail out and from the locking bar to lock the switch tongue up against the foot of the pole rail or against the foot the rail rail arranged closure carrier is pressed.
- switch blades with longer lengths as they are necessary for larger radii of curvature occur when driving on unwanted vibrations.
- These switch tongues are also more susceptible to torsion, whereby a lifting of the switch tongue can occur from the floor rail.
- a closure device is known in which a positive connection of the switch blade with the floor rail is sought. This is achieved by providing the closure bearing connected to the switch blade tongue with an extension which, when the fastener device is locked, presses against a fastener support rigidly connected to the rod rail, whereby the switch blade is rotated around the lock bearing and pressed against the pole rail in a form-fitting manner.
- closure carrier is held at the foot of the floor rail by clamping the foot of the floor rail and / or the closure pawl in a closure bearing fastened directly to the switch tongue. It is therefore easily understandable that, in particular, in countries with a wide variety of track and switch tongue profiles, e.g. In the United States, the United Kingdom and Japan, a correspondingly large number of different closure carriers and / or lock stock should be stockpiled and used as needed. Both the storage and the need-based use are therefore complicated and expensive in view of the variety of existing profiles. With only slight deviations of the profiles from each other there is even the risk of confusion by the assembly team, the such switch assemblies usually under "rolling train" and therefore must always make under a certain time pressure. However, a confusion can lead to premature wear or even serious malfunctions.
- the turnout gliding chair proves to be particularly suitable here.
- This slide chair can also be used as Turnout plain bearings or be designed as switch blade roller bearings.
- a Weichenverstellvorraum can also be integrated into a hollow sleeper body.
- the stationary track superstructure component is arranged on a rising flank of a U-shaped profile having a threshold body.
- Fig. 3 shows one from the EP 0 624 508 A1 Known closure device 2, which has a connected via an axis 4 and a lock bearing 6 with a switch tongue 8 closure pawl 10, which after closing on a surface 12 of a connected to a rail 14 rail carrier 16 positively abuts and therein by a Locking rod 18 is locked.
- the closure bearing 6 is provided at the bottom with an extension, not shown, which abuts the closure carrier 16 when the closure device is closed, which transfers a force F1 to the closure bearing 6, by which a head 20 of the switch tongue 8 is pressed against the head 22 of the floor rail 14 ,
- the closure bearing 6 is connected by a screw 24 to the foot 26 of the switch blade 8, which is designed such that the foot 26, when the head 20 of the switch blade 8 to the head 22 of the floor rail 14, over the foot 28 of the floor rail 14th lies. It is therefore easy to see that the closure bearing 6 can be easily attached to the foot 26 of the switch blade 8.
- the closure carrier 16 can be clamped by means of a clamping screw 30 and a clamp hook 32 on the foot 28 of the floor rail 14.
- this embodiment of the closure device 2 is no longer usable, for example, if there is another profile of the switch blade 8 and therefore no space for the attachment of the clip hook 32 is given to the foot 28 of the floor rail 14. Also problematic is this embodiment, if within a rail network very much different profiles for the stock rails and the switch blades exist. In this case, a separate lock bearing and a separate lock carrier must be used for each profile.
- FIG. 1 now shows a schematic side view of a first inventive closure device 100, wherein the storage of a closure carrier 102 and a closure bearing 104 to one of the respective profiles of the floor rail 14 and one opposite FIG. 3 changed switch tongue 106 independent manner is solved.
- the closure support 102 is - as in FIG. 3 - On the side facing away from the switch blade 106 side 108 by means of a positively clamped on the foot 28 of the floor rail 14 attached.
- an abutment in the form of a bolt 110 is provided, so that the closure carrier 102 can be clamped by means of a clamping screw 112 and a hook rod 114.
- the bolt 110 is mounted in a manner not shown here on a track superstructure component, such as on the inside of a hollow sleeper body or on the underside of a plain bearing for the switch blade 106.
- the bolt 110 has been arranged so far below the foot 26 of the switch blade 106 in this illustration, only for the sake of better illustration in principle.
- the mounting of the lock 104 is also solved in a manner that allows the use of completely different switch tongue profiles.
- the closure bearing 104 is therefore supported by a slide plate 118 which is in sliding contact with a track superstructure component.
- the track superstructure component is a cover plate 119, which is shown only in sections, which closes the cavity of a hollow sleeper or a sleeper compartment at the top.
- cover plate 119 are L-shaped guides 121 arranged on the horizontally extending portion 123, the slide plate 118 slides.
- the slide plate 118 With an adjustment movement of the switch tongue 106, the slide plate 118 is thus moved back and forth between its two end positions of the sliding movement.
- a rolling bearing or the like can also be used.
- the slide plate 118 is thus on the guides 121, 123, which also serve as a sliding bearing on.
- the guide 121, 123 carries the weight of the closure bearing 104.
- the closure pawl 10 is still supported on the axis 4 in the closure bearing 104.
- a push rod 120 is slidably mounted in a bore. The push rod 120 is locked in each case in an end position, which allows the end face 122 of the push rod 120 to abut exactly at the switch tongue 106.
- the above-mentioned coupling rod between the two switch blades 106 can also be solved by means of a continuous slide plate 118 which either itself has on the switch blades 106 coupling elements or is part of an arrangement in which the push rods 120 not only in are able to push a switch tongue in its desired position, but also to pull in a desired position. Especially in the latter case, however, it may then be advantageous again to carry out the slide plate 118 separately for each closure bearing 104. That's how it turns out a Auffahrle the switch, without the slide plate 118 is damaged, which would be the case with a continuous sliding plate 118, because when driving in any case, the second of the switch blades 106 are forced into the remote from the floor rail 14 location.
- a second closure device 130 is shown in a schematic side view in FIG FIG. 2 shown. For reasons of clarity, essentially only the holder of a closure carrier 132 and a closure bearing 134 are shown.
- the entire closure device 130 is integrated into an upwardly open, hollow sleeper body 136 which has a U-shaped profile and has outwardly directed flanges 138. On these flanges 138 a secured by screw 139 sliding chair 140 for a switch blade 142 is mounted. Also, with respect to the profile with respect to the above-described stock rails 14 modified floor rail 144 is fastened by means of screw 146 on the flanges 138.
- a laterally projecting pin 148 is provided which serves as an abutment for fastening the closure carrier 132.
- the closure support encloses so during its installation, first the foot 150 of the floor rail 144 on the outside 152 and by means of a clamping screw 154, which clamps a bolt 148 engaging around the hook rod 156, attached. This attachment is provided on both attached to the flanges 138 sliding chairs 140.
- a clamping screw 154 which clamps a bolt 148 engaging around the hook rod 156, attached.
- This attachment is provided on both attached to the flanges 138 sliding chairs 140.
- the closure bearing 134 is again attached to a slide member 135, which itself rolling (dotted lines indicated rollers 137) in a arranged on the inwardly facing side surfaces of the sliding chairs 140 guide track 141 runs in the lock bearing 134 is again the locking pawl (also not shown here) rotatably mounted about the axis 4 in an eccentric bushing 5 (see. FIG. 1 ) held.
- the closure bearing 134 also has a substantially horizontal bore, in which a push rod 156 is slidably held. By means of a arranged on the push rod 156 thread the push rod 156 can be firmly connected to the switch blade 142.
- the push rod 156 has a roller-shaped recess 158, in which a by means of a spring 160 acted upon roller body 162 is pressed.
- the spring 160 is clamped by means of a screw 164, which is screwed into a vertically extending spring shaft 166.
- a thickness selection for a washer 168 By means of a thickness selection for a washer 168, a predefined holding force can thus be exerted on the push rod 156.
- the holding force is chosen so that a cutting of the over-run in the wrong direction switch is possible.
- the second closure device 130 shows the desired advantages of easy adaptability to different profiles of the floor rail 144 and the Switch blades 142, as could be demonstrated with the first closure device 100.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Verstellen einer Weichenzunge nach dem Obesbegriff des Patentauspmchs 1.The present invention relates to a device for adjusting a switch tongue according to the preamble of Patentausмchs. 1
Zur Sicherung von Weichenzungen werden Eisenbahnweichen mit Verschlussvorrichtungen ausgerüstet, wie sie z.B. in der europäischen Patentanmeldung
Insbesondere bei Weichenzungen mit grösseren Längen, wie sie bei grösseren Kurvenradien notwendig sind, treten beim Befahren unerwünschte Schwingungen auf. Diese Weichenzungen sind zudem vermehrt torsionsgefährdet, wodurch ein Abheben der Weichenzunge von der Stockschiene auftreten kann. Aus der
Aus der deutschen Patentanmeldung
Allen vorstehend genannten Zitatstellen ist es gemeinsam, dass der Verschlussträger am Fuss der Stockschiene unter beidseitiger Umklammerung des Fusses der Stockschiene und/oder die Verschlussklinke im einem direkt an der Weichenzunge befestigten Verschlusslager gehalten ist. Es ist daher leicht nachvollziehbar, dass im besonderen in Ländern mit einer grossen Vielfalt an Gleis- und Weichenzungenprofilen, z.B. den USA, Grossbritannien und Japan, eine entsprechend grosse Anzahl unterschiedlicher Verschlussträger und/oder Verschlusslager zu bevorraten und bedarfsgerecht einzusetzen ist. Sowohl die Bevorratung als auch der bedarfgerechte Einsatz sind angesichts der Vielzahl vorhandener Profile daher aufwendig und teuer. Bei nur geringen Abweichungen der Profile voneinander besteht sogar die Gefahr einer Verwechslung durch das Montageteam, das derartige Weichenmontagen in der Regel unter "rollendem Zug" und daher immer unter einem gewissen Zeitdruck vornehmen muss. Eine Verwechslung kann jedoch zu vorzeitigem Verschleiss oder gar zu ernsthaften Funktionsstörungen führen.It is common to all of the abovementioned quotation points that the closure carrier is held at the foot of the floor rail by clamping the foot of the floor rail and / or the closure pawl in a closure bearing fastened directly to the switch tongue. It is therefore easily understandable that, in particular, in countries with a wide variety of track and switch tongue profiles, e.g. In the United States, the United Kingdom and Japan, a correspondingly large number of different closure carriers and / or lock stock should be stockpiled and used as needed. Both the storage and the need-based use are therefore complicated and expensive in view of the variety of existing profiles. With only slight deviations of the profiles from each other there is even the risk of confusion by the assembly team, the such switch assemblies usually under "rolling train" and therefore must always make under a certain time pressure. However, a confusion can lead to premature wear or even serious malfunctions.
Es ist daher die Aufgabe der Erfindung eine Verstell- und Verschlussvorrichtung für Weichenzungen anzugeben, die mit einer besonders geringen Teilezahl trotz Vorhandensein verschiedener Schienen- und Zungenprofile auskommt und zugleich die Arbeit des Montageteams effizient macht und Fehlerquellen weitgehend ausschliesst.It is therefore an object of the invention to provide an adjustment and closure device for switch blades, which manages with a very small number of parts despite the presence of different rail and tongue profiles and at the same time makes the work of the assembly team efficient and excludes sources of error largely.
Diese Aufgabe wird bei der eingangs genannten Verstell- und Verschlussvorrichtung erfindungsgemäss durch die Mehmale des kemzeichuendeu Teils von Patentamspruch 1 gelast.This object is achieved according to the invention in the above-mentioned adjusting and closing device by the Mehmale of kemzeichuendeu part of patent claim 1 gelastu.
Auf diese Weise gelingt die Befestigung des Verschlussträgers an der Stockschiene, ohne dass auf der der Weichenzunge zugewandten Seite der Stockschiene Befestigungselemente an der Stockschiene zu befestigen wären. Damit ergibt sich ein "freies" Innenraumprofil, an welches sich die unterschiedlichsten Weichenzungenprofile anlegen können.In this way, the fastening of the closure carrier succeeds on the floor rail, without fastening elements to be fastened to the floor rail on the side of the floor rail facing the switch point. This results in a "free" interior profile, to which can create the most diverse switch blade profiles.
Als besonders geeignet erweist sich hierbei der Weichenzungengleitstuhl. Dieser Gleitstuhl kann auch als Weichenzungengleitlager oder als Weichenzungenrolllager ausgeführt sein.The turnout gliding chair proves to be particularly suitable here. This slide chair can also be used as Turnout plain bearings or be designed as switch blade roller bearings.

Diese Ausführungsform der Verschlussvorrichtung 2 ist jedoch nicht mehr verwendbar, wenn beispielsweise ein anderes Profil der Weichenzunge 8 vorliegt und deshalb am Fuss 28 der Stockschiene 14 kein Raum für die Befestigung des Klammerhaken 32 gegeben ist. Ebenfalls problematisch ist diese Ausführungsform, wenn innerhalb eines Schienennetzes sehr viel unterschiedliche Profile für die Stockschienen und die Weichenzungen existieren. In diesem Fall müssen für jedes Profil ein separates Verschlusslager und ein separater Verschlussträger eingesetzt werden.However, this embodiment of the closure device 2 is no longer usable, for example, if there is another profile of the switch blade 8 and therefore no space for the attachment of the clip hook 32 is given to the
Der Verschlussträger 102 ist - wie schon in
Durch diese Lagerung mit dem Konzept des an einer in der Regel meist ohnehin vorhandenen Gleisoberbaukomponente angeordneten Gegenlagers verbleibt auf dem der Weichenzunge 106 zugewandten Innenraum 116 genügend freier Raum, um auch Weichenzungen 106, die aus dem Profil der Stockschiene 14 herausgefräst sind, an die Stockschiene 14 heranzuführen.By means of this mounting with the concept of the abutment element arranged on a usually already existing track superstructure component, sufficient free space remains on the
Die Halterung des Verschlusslagers 104 ist ebenfalls in einer Weise gelöst, die die Verwendung vollkommen unterschiedlicher Weichenzungenprofile erlaubt. Das Verschlusslager 104 ist daher mittels einer Gleitplatte 118 gelagert, welche auf Gleitsitz mit einer Gleisoberbaukomponente in Eingriff steht. Im vorliegenden Beispiel ist die Gleisoberbaukomponente eine nur ausschnitthaft dargestellte Abdeckplatte 119, welche den Hohlraum einer Hohlschwelle oder eines Schwellenfachs nach oben hin abschliesst. An dieser Abdeckplatte 119 sind L-förmige Führungen 121 angeordnet, auf deren waagrecht verlaufender Teil 123 die Gleitplatte 118 gleitet. Damit wird die Verstellbewegung von der Verschlussstange 18 über die Verschlussklinke 10 auf das an der Gleitplatte 118 befestigte Verschlusslager 104 übertragen. Mit einer Verstellbewegung der Weichenzunge 106 wird so die Gleitplatte 118 zwischen ihren zwei Endpositionen der Gleitbewegung hin- bzw. herbewegt. Alternativ zu einer gleitenden Auflage der Gleitplatte 118 kann auch eine rollende Lagerung oder dergleichen eingesetzt werden. Die Gleitplatte 118 liegt damit auf den Führungen 121, 123, die auch als Gleitlager dienen, auf. Damit trägt die Führung 121, 123 das Gewicht des Verschlusslagers 104. Die Verschlussklinke 10 ist dabei nach wie vor auf der Achse 4 in dem Verschlusslager 104 gelagert. In oberen Teil des Verschlusslagers 104 ist in einer Bohrung eine Stösselstange 120 verschiebbar gelagert. Die Stösselstange 120 wird jeweils in einer Endlage arretiert, die es der Stirnseite 122 der Stösselstange 120 erlaubt, genau an der Weichenzunge 106 anzuliegen. Bei einer Verstellung der Weiche stösst daher die Stösselstange 120 die Weichenzunge 106 in die in der
Eine zweite Verschlussvorrichtung 130 ist in einer schematischen seitlichen Ansicht in
Jeweils auf den nach innen gerichteten Seiten der Gleitstühle 140 ist ein seitlich abstehender Bolzen 148 vorgesehen, der als Gegenlager zur Befestigung des Verschlussträgers 132 dient. Der Verschlussträger umschliesst so bei seiner Montage zunächst den Fuss 150 der Stockschiene 144 auf deren Aussenseite 152 und wird mittels einer Spannschraube 154, welche eine den Bolzen 148 umgreifende Hakenstange 156 verspannt, befestigt. Diese Befestigung ist an beiden auf den Flanschen 138 befestigten Gleitstühlen 140 vorgesehen. Angesichts der hier vorliegenden Profile von Stockschiene 144 und Weichenzungen 142 ist leicht nachvollziehbar, dass am Fuss 150 der Stockschiene 144 auf deren Innenseite kein Raum für die Befestigung des Verschlussträgers 132 vorhanden gewesen wäre. Die Befestigung des Verschlussträgers 132 kann jedoch in der vorstehend beschriebenen Weise ohne eine Bohrung in der Stockschiene gelöst worden, was vielfach von Bahninfrastrukturbetreibern gefordert ist.In each case on the inwardly directed sides of the sliding
Entsprechend flexible ist auch die Befestigung des Verschlusslagers 134 gelöst. Das Verschlusslager 134 wird wieder an einem Gleitteil 135 befestigt, welches selbst rollend (punktiert angedeutete Rollen 137) in einer an den nach innen gerichteten Seitenflächen der Gleitstühle 140 angeordneten Führungsbahn 141 läuft.In dem Verschlusslager 134 ist wieder die Verschlussklinke (hier ebenfalls nicht dargestellt) drehbar um die Achse 4 gelagert in einer Exzenterbuchse 5 (vgl.
Zusätzlich verfügt die Stösselstange 156 über eine walzenförmige Ausnehmung 158, in welche ein mittels einer Feder 160 beaufschlagter Walzenkörper 162 eingedrückt wird. Die Feder 160 wird dabei mittels einer Schraube 164 gespannt, die in einen vertikal verlaufenden Federschacht 166 eingedreht wird. Mittels einer Dickenauswahl für eine Unterlegscheibe 168 kann so eine vordefinierte Haltekraft auf die Stösselstange 156 ausgeübt werden. Dabei wird die Haltekraft so gewählt, dass ein Aufschneiden der in verkehrter Richtung überfahrenen Weiche ermöglicht ist. Durch den in die verschlossene Weichenzunge 142 eindringenden Radkranz wirkt auf die Weichenzunge 142 eine Kraft in Richtung eines Pfeils 170, die mit Überwindung der durch die Feder 160 ausgeübten Haltekraft die Stösselstange 156 in Richtung 170 verschiebt. Damit ist zwar eine Nachjustierung der Stösselstange 156 erforderlich geworden, eine weitergehende Zerstörung der Verstellvorrichtung durch das Aufschneiden kann aber so sicher vermieden werden.In addition, the push rod 156 has a roller-shaped recess 158, in which a by means of a spring 160 acted upon roller body 162 is pressed. The spring 160 is clamped by means of a
Damit zeigt auch die zweite Verschlussvorrichtung 130 die gewünschten Vorteile der leichten Anpassbarkeit an unterschiedliche Profile der Stockschiene 144 und der Weichenzungen 142, wie dies auch schon mit der ersten Verschlussvorrichtung 100 demonstriert werden konnte.Thus, the
