Abstract

An eccentric bolt (EB) (1) has a cylinder (3) with an eccentric mounting for adjusting switch blade clearance on a set of railway points,. A fixing disk (5) ensures an adjusted position and acts as a safety-related recoil surface, because the EB moves radially and on-axis. A screw (7) forces a self-locking cone (2) into a larger cylinder on the EB.

Description

Die vorliegende Erfindung betrifft einen Exzenterbolzen für Weichenverschlüsse nach dem Oberbegriff der Patentansprüche 1 und 2.The present invention relates to an eccentric bolt for Switch closures according to the preamble of patent claims 1 and 2.

Durch höhere zulässige Geschwindigkeiten von Eisenbahnzügen nimmt die Beanspruchung des Schienenoberbaus und insbesondere jene der Weichen erheblich zu. Mit einem Exzenterbolzen wird für einen Weichenverschluss der Zungenabstand - auch Zungenklaffung oder Zungenspiel genannt - eingestellt. Der Zungenabstand zwischen Stockschiene (auch Backenschiene genannt) und Zungenschiene weist Toleranzen von ca. ± 4 mm auf, weil die Stockschiene als gewalztes Produkt nicht genauer hergestellt werden kann.Due to higher permissible speeds of railway trains takes the strain on the track superstructure and in particular that of the switches considerably. With an eccentric bolt for a switch closure the tongue spacing - also tongue gaping or called tongue play - set. The tongue spacing between stick rail (also called stock rail) and tongue rail has tolerances of approx. ± 4 mm because the stick rail as a rolled product was not manufactured more precisely can be.

Die bekannten Exzenterbolzen sind mit einem Schiebesitz im Verschlusslager gelagert. Der Exzenterbolzen konnte sich in seinen Freiheitsgraden, d.h. axial und radial, etwas bewegen. Ebenso musste ein Spiel zwischen Exzenterbolzen und einer Fixierscheibe vorgesehen werden, da die Fixierscheibe von der Sicherungsschraube nicht an das Verschlusslager angepresst werden darf, weil sonst bei einer Drehung des Exzenterbolzens innerhalb seines Spiels die Gefahr bestanden hätte, dass die Sicherungsschraube aufgedreht wird. Mit einer Zweikantkopplung kann die Fixierscheibe auf nur eine Art an den Exzenterbolzen gekoppelt werden. Mit verschiedenen radial angeordneten Löchern kann eine bestimmte Position der Fixierscheibe und damit des Exzenterbolzens eingestellt werden. Auf diese Weise wird der Abstand der Zungenklaffung vor Ort eingestellt und fixiert. Eines der vorgenannten Löcher greift dabei in einen am Verschlusslager eingepressten Passkerbstift ein.The known eccentric bolts are with a sliding seat in Locking bearings stored. The eccentric bolt could its degrees of freedom, i.e. axially and radially, move something. There was also a game between the eccentric bolt and one Fixing washer are provided because the washer from the The locking screw is not pressed against the lock bearing may be, because otherwise when the eccentric bolt turns within his game there was a risk that the Locking screw is unscrewed. With a double-sided coupling the fixing washer can only be attached to the Eccentric bolts are coupled. With different radial arranged holes can be a specific position of the fixing washer and thus the eccentric bolt can be adjusted. On in this way the gap between the tongues is adjusted on site and fixed. One of the aforementioned holes engages thereby in a dowel pin pressed into the lock bearing on.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Exzenterbolzen anzugeben, der bei der Montage so verspannt werden kann, dass zwischen Exzenterbolzen und Verschlusslager kein Spiel mehr auftreten kann und dass beeinem verspannbaren Exzenterbolzen nachgerüstet werden können.The present invention is therefore based on the object specify an eccentric bolt that tensions during assembly that can be between the eccentric bolt and the lock bearing no more game can occur and that affect tensionable eccentric bolts can be retrofitted can.

    Fig. 1 zeigt einen Exzenterbolzen 1 für Weichenverschlüsse in herkömmlicher Bauart mit zwei konzentrisch angeordneten Zylindern 20, 20' zur Aufnahme in einem nicht dargestellten Verschlusslager 11. Zwischen den beiden Zylindern 20, 20' befindet sich ein exzentrisch angeordneter Zylinder 3. Für die Einstellung des Zungenabstandes ist ein Innensechskant 21 vorgesehen, in den mit einem eingesetzten Inbussschlüssel der Exzenterbolzen 1 gedreht werden kann. Durch Drehen des Inbusschlüssels lässt sich somit der Zungenabstand einstellen. Auf den Zweikant 18 kann die Fixierscheibe 5 gesetzt werden. Mit einer in der Bohrung 19 befindlichen Sechskantschraube 7 (nicht dargestellt) wird die Fixierscheibe 5 in ihrer Position gehalten, ohne dass sie an das Verschlusslager 11 angepresst wird.Fig. 1 shows an eccentric bolt 1 for switch closures in conventional design with two concentrically arranged cylinders 20, 20 'for inclusion in a not shown Locking bearing 11. Between the two cylinders 20, 20 ' there is an eccentrically arranged cylinder 3. For the setting of the tongue spacing is a hexagon socket 21 provided in the with an inserted Allen key Eccentric bolt 1 can be rotated. By turning the The tongue spacing can thus be adjusted using an Allen key to adjust. The fixing disc 5 can be placed on the square 18 be set. With one located in the bore 19 Hexagon screw 7 (not shown) becomes the fixing washer 5 held in position without touching the Lock bearing 11 is pressed.

    Fig. 2a eine bevorzugte Ausführungsform eines Exzenterbolzens 1 für Weichenverschlüsse mit zwei konzentrisch angeordneten Zylindern 20, 20' zur Aufnahme in einem Verschlusslager 11. Um einen bestehenden Weichenverschluss mit einem Exzenterbolzen 1 der erfindungsgemässen Gattung nachrüsten zu können, sind die Abmessungen gegenüber Verschlusslager 11 und Verschlussklinke 12 weitgehend identisch. Der grössere Zylinder 20 weist in seinem Inneren eine konische Form auf, in die formschlüssig ein Konus 2 einschiebbar ist. Mit einer Sechskantschraube 7 wird der Konus 2 (beide nicht dargestellt) gegen den Zylinder 20 gedrückt, so dass dieser gegenüber dem Verschlusslager 11 verspannt werden kann. Dazu weist der Exzenterbolzen 1 unmittelbar nach dem Innensechskant ein Gewinde auf, in das die Sechskantschraube 7 eingreift. Vorzugsweise sind am Zylinder 20 mehrere Schlitze 22 vorgesehen, um eine bessere Verspannung bzw. Aufdrückbarkeit zu bewirken.Fig. 2a shows a preferred embodiment of an eccentric bolt 1 for switch locks with two concentrically arranged Cylinders 20, 20 'for receiving in a lock bearing 11. Around an existing switch lock with an eccentric bolt To be able to retrofit the genus according to the invention, are the dimensions compared to locking bearing 11 and locking pawl 12 largely identical. The bigger cylinder 20 has a conical shape on the inside into which a cone 2 can be inserted in a form-fitting manner. With a hexagon screw 7 the cone 2 (both not shown) pressed against the cylinder 20 so that it is opposite the Lock bearing 11 can be clamped. The Eccentric bolt 1 immediately after the hexagon socket in which the hexagon screw 7 engages. Preferably are several slots 22 provided on the cylinder to to bring about better tension or press-fit.

    In den Fig. 2b und 2c ist je eine Vorder- und Hinter-Ansicht des Exzenterbolzens gemäss der Darstellung in Fig. 2a gezeigt.2b and 2c are front and rear views of the eccentric bolt as shown in Fig. 2a shown.

    Für die Erläuterung der weiteren Teile wird zunächst Bezug auf die Fig. 3 genommen. Der Konus 2 weist - wie auch vorstehend zum Stand der Technik erläutert - einen Innensechskant 21 auf. Um mit einem Inbusschlüssel eine Einstellung vornehmen zu können, muss auch im noch nicht angepressten Zustand der Konus eine feste Kopplung mit dem Exzenterbolzen 1 aufweisen. Dazu ist eine ovale Ausnehmung 23 im Exzenterbolzen 1 vorgesehen. Im Detail ist dies der Fig. 2b zu entnehmen. In diese Ausnehmung 23 greift formschlüssig ein ovaler Vorsprung 24 des Konus 2 ein. Es wäre auch möglich, in einer anderen Ausführungsform die Funktion von ovalem Vorsprung 24 und ovaler Ausnehmung 23 vertauscht vorzusehen.For the explanation of the other parts, reference is first made taken on Fig. 3. The cone 2 has - as also above explained to the prior art - a hexagon socket 21 on. To make a setting with an Allen key To be able to make, does not have to be pressed Condition of the cone a firm coupling with the eccentric bolt 1 have. For this there is an oval recess 23 in the eccentric bolt 1 provided. This can be seen in detail in FIG. 2b. This recess 23 engages in a form-fitting manner oval projection 24 of the cone 2. It would also be possible to another embodiment, the function of oval projection 24 and oval recess 23 are interchanged.

    Aus der Fig. 2c ist die Lage des exzentrisch angeordneten Zylinders 3 ersichtlich. Damit der Exzenterbolzen 1 von rechts her (siehe dazu Fig. 3) bei der Montage in das Verschlusslager 11 und die Verschlussklinke 12 eingeschoben werden kann, darf der exzentrisch angeordneten Zylinder 3 die Umhüllung des grösseren Zylinders 20 nicht überschreiten.2c shows the position of the eccentrically arranged cylinder 3 can be seen. So that the eccentric pin 1 from the right forth (see Fig. 3) during assembly in the lock bearing 11 and the locking pawl 12 are inserted can, the eccentrically arranged cylinder 3 may the envelope of the larger cylinder 20 do not exceed.

    Durch Anziehen der Sechskantschraube 7 wird der Konus 2 in den grösseren Zylinder 20 des Exzenterbolzens 1 gepresst. Zur Kraftübertragung zwischen Schraubenkopf und Exzenterbolzen 1 dient eine Unterlagscheibe 9. Die konische Form zwischen Konus 7 und dem Innern des grösseren Zylinders 20 ist selbsthemmend gewählt. Durch die Verspannung des geschlitzten Zylinders 20 kann sich nun der Exzenterbolzen 1 nicht mehr drehen. Aus diesem Grunde darf die Fixierscheibe 5 an das Verschlusslager 11 angepresst werden. Unter Verwendung eines herkömmlichen Exzenterbolzens 1' darf die Fixierscheibe 5 deshalb nicht angepresst werden, weil durch eine mögliche Drehung des Exzenterbolzens die Schraube 7 gelöst werden könnte und dadurch die Fixierscheibe 5 nicht mehr die Lage des Exzenterbolzens feststellt. Gemäss der vorliegenden Erfindung ist die Fixierscheibe kein sicherheitsrelevantes Teil mehr, sondern bildet nur noch eine Rückfallebene, falls die Verspannung des Exzenterbolzens 1 versagen sollte. Diese Rückstufung auf eine Rückfallebene gilt auch für den Passkerbstift 10. Die Verspannung des Exzenterbolzens 1 bewirkt auch eine deutliche Reduktion des Verschleisses und hilft, den Wartungs- und Kontrollaufwand reduzieren zu können.By tightening the hexagon screw 7, the cone 2 in the larger cylinder 20 of the eccentric bolt 1 is pressed. to Power transmission between screw head and eccentric bolt 1 serves a washer 9. The conical shape between Cone 7 and the inside of the larger cylinder 20 is self-locking selected. By bracing the slotted Cylinder 20, the eccentric bolt 1 can no longer rotate. For this reason, the fixing disc 5 to the Lock bearing 11 are pressed. Using a conventional eccentric bolt 1 ', the fixing washer 5 therefore not be pressed because of a possible Rotation of the eccentric bolt 7 can be loosened could and thereby the fixing disc 5 no longer the position of the eccentric bolt. According to the present invention the fixing washer is not a safety-relevant part more, but only forms a fallback level if the The tensioning of the eccentric bolt 1 should fail. This Downgrading to a fallback level also applies to the passport notch pin 10. The tensioning of the eccentric bolt 1 causes also a significant reduction in wear and helps to be able to reduce the maintenance and control effort.

    Zum Einpressen des Konus 2 kann auch eine andere Schraube als eine Sechskantschraube 7 vorgesehen sein, aus Gründen der Kompatibilität zum konventionellen Exzenterbolzen und aus Gründen der Reduktion der Teilevielfalt wird jedoch vorzugsweise die genannte Sechskantschraube 7 beibehalten.Another screw can be used to press in the cone 2 a hexagon screw 7 may be provided for the sake of Compatibility with the conventional eccentric bolt and out However, it is preferred to reduce the variety of parts maintain the aforementioned hexagon screw 7.

    Um eine gute Dämpfung zu erlangen, wird kann zwischen dem Zylinder 3 und der Verschlussklinke 2 eine Büchse 8 aus elastischem Material vorgesehen sein. Als Material wird vorzugsweise Gummi gewählt. Da beim Befahren einer Weiche durch einen Zug besonders hohe Beschleunigungen (Vibrationen) auftreten wird zusätzlich ein Hubbegrenzungsring 14 eingebaut, damit auftretende Belastungen symmetrisch auf die Verschlussklinke 12 übertragen werden. Auf der anderen Seite des exzentrisch angeordneten Zylinders 3 ist ein Ring 6 - als Teil des ganzen Exzenterbolzens 1 , der Fig. 2c nur indirekt zu entnehmen - vorgesehen, dessen Durchmesser gleich dem Durchmesser des Hubbegrenzungsringes 14 ist. Dies ist erforderlich, weil die Büchse 8 aus Gummi den auftretenden Hub bzw. Hubverschiebung nicht starr überträgt.To achieve good damping, you can choose between the Cylinder 3 and the locking pawl 2 from a sleeve 8 elastic material may be provided. As material preferably chosen rubber. Because when driving on a switch particularly high accelerations (vibrations) due to a train a stroke limiting ring 14 is additionally installed, thus occurring loads symmetrically on the locking latch 12 are transmitted. On the other side of the eccentrically arranged cylinder 3 is a ring 6 - as Part of the entire eccentric bolt 1, Fig. 2c only indirectly to remove - provided whose diameter is equal to that Diameter of the stroke limiting ring 14. This is required because the sleeve 8 made of rubber the stroke occurring or stroke displacement is not rigidly transmitted.

    Als weitere Rückfallebene dient die Schraubensicherung 17, die über das Verschlusslager 11 einschliesslich der Fixierscheibe 5 gestülpt wird und die Verschlussklammerschraube 15 sichert. Die Zwischenlagen 16 dienen der Einstellung der Maultiefe beim Verschlusslager 11 an die Distanz Zungenbohrung - Zungenaussenkante. Mit ihnen soll verhindert werden, dass sich das Verschlusslager 11 um die Verschlussklammerschraube 15 dreht.The screw lock 17 serves as a further fallback level. that about the locking bearing 11 including the fixing washer 5 is put over and the locking clip screw 15 guaranteed. The intermediate layers 16 are used to adjust the Mouth depth at the locking bearing 11 to the distance of the tongue hole - tongue outer edge. With them should be prevented be that the locking bearing 11 around the locking clip screw 15 turns.

    Die vorliegende Erfindung ist nicht auf die vorstehend erläuterte Ausführungsform beschränkt. Es könnte auch vorgesehen sein, dass das anstelle des einen Zylinders 20 ein zylinderartiges Teil - ebenfalls Konus genannt - gewählt wird, in das ein konisch ausgebildeter Zylinder einschiebbar ist um eine Verspannung bzw. Aufweitung des Konus 2' (in den Figuren nicht dargestellt) zu erwirken um damit eine feste Verbindung mit dem Verschlusslager 11 zu bewirken. Vorzugsweise weist die besseren Aufweitbarkeit oder Aufdrückbarkeit dieser Konus 2' ebenfalls Schlitze auf. The present invention is not limited to that explained above Embodiment limited. It could also be provided be that instead of the one cylinder 20 a cylindrical part - also called cone - selected into which a conical cylinder can be inserted is a bracing or expansion of the cone 2 '(in the Figures not shown) to achieve a fixed To effect connection with the lock bearing 11. Preferably shows the better expandability or pressability this cone 2 'also has slots.
