Description

Die Erfindung betrifft eine Stangenanordnung, insbesondere Zungenprüferanordnung für Weichen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a rod assembly, in particular Tongue checker arrangement for switches, according to the preamble of Claim 1.

Die nachfolgenden Erläuterungen beziehen sich im Wesentlichen auf eine Zungenprüferanordnung für Weichen für Schienenfahrzeuge, ohne dass der Schutzbereich auf diese spezielle Anwendung beschränkt sein soll.The following explanations essentially relate on a tongue checker arrangement for switches for rail vehicles, without the scope of protection to this particular application should be limited.

Zungenprüfer dienen dazu, den Ist-Zustand der Weiche, d. h. die aktuelle Lage der beiden Weichenzungen relativ zu den Backenschienen, mechanisch abzutasten und ein Prüfsignal zu erzeugen, anhand dessen zuverlässig festgestellt werden kann, ob die Weiche korrekt umgestellt wurde und ob sich die anliegende und die ablegende Weichenzunge in ihrer jeweiligen vorgegebenen Endlage befinden. Die Prüferstangen erstrecken sich im Wesentlichen quer zu den Weichenzungen und werden beim Umstellen der Weiche in ihrer Längsrichtung verschoben. Die Positionen der Prüferstangen werden mit Hilfe von elektromechanischen Wandlern, beispielsweise durch Endschalter, erfasst, die durch einen Schaltfinger der Prüferstange betätigt werden. Da die Zungenp0rüferanordnung für verschiedene Montageorte mit unterschiedlichem Abstand zum Weichenzungenende geeignet sein muss, ist die Prüferstange üblicherweise in zwei drehfeste Stangenstücke unterteilt, die zwecks Längeneinstellung über ein Zwischenstück miteinander verbinden sind. Häufig wird als Zwischenstück eine Überwurfmutter verwendet, die einerseits ein Linksgewinde und andererseits ein Rechtsgewinde aufweist, welche in entsprechende Gewindeenden der Stangenstücke eingreifen. Durch Drehung der Überwurfmutter werden die Stangenstücken entweder aufeinander zubewegt oder voneinander entfernt, so dass auf diese Weise der Abstand zwischen den Stangenstücken und damit die Gesamtlänge der Zungenprüferanordnung einstellbar ist. Dabei muss gewährleistet sein, dass eine unbeabsichtigte Längenverstellung, beispielsweise durch zufällige oder erschütterungsbedingte Einwirkung auf das Zwischenstück, quasi ausgeschlossen ist.Tongue checkers are used to determine the actual state of the switch, d. H. the current position of the two switch blades relative to the jaw rails, mechanically scan and generate a test signal, can be reliably determined by means of which whether the switch was changed over correctly and whether the adjoining and the depositing switch tongue in their respective predetermined End position are located. The Prüferstangen extend essentially transverse to the switch blades and are used when switching the switch shifted in its longitudinal direction. The positions The tester bars are made with the help of electromechanical Transducers, for example by limit switches detected, which are actuated by a shift finger of the Prüferstange. Because the tongue tracker assembly for different mounting locations suitable with different distance to the switch blade end usually the examiner bar is in two rotatable rod pieces divided, for the purpose of length adjustment connect to each other via an intermediate piece. Often is used as an intermediate piece a union nut, the on the one hand a left-hand thread and on the other hand a right-hand thread having, which in corresponding threaded ends of the rod pieces intervention. Turn the union nut the rod pieces either moved towards each other or from each other away, so that way the distance between the rod pieces and thus the total length of the tongue checker assembly is adjustable. It must be ensured that that an unintentional length adjustment, for example due to accidental or vibration-induced effects the intermediate piece, quasi excluded.

Aus der DE 198 40 328 C1 ist ein Verriegelungsmechanismus bekannt, bei dem eine Hülse formschlüssig auf ein Stangenstück und das Zwischenstück aufgeschoben wird. Die Hülse steht in Verschieberichtung unter Vorspannung und muss gegen diese Vorspannung zum Zwecke der Verstellung des Zwischenstückes zurückgeschoben werden, wobei sich die Hülse hernach selbsttätig über das Zwischenstück schiebt und die Verriegelung bewirkt.From DE 198 40 328 C1 a locking mechanism is known, in which a sleeve form-fitting manner on a rod piece and the intermediate piece is pushed. The sleeve is in Displacement direction under bias and must be against this Preload for the purpose of adjusting the intermediate piece be pushed back, with the sleeve afterwards automatically slides over the spacer and causes the lock.

Der Erfindung liegt die Aufgabe zugrunde, eine Stangenanordnung der gattungsgemäßen Art anzugeben, bei der die Längeneinstellung, insbesondere hinsichtlich Verschleiß und Handling vereinfacht ist.The invention is based on the object, a rod assembly specify the generic type in which the length adjustment, especially regarding wear and handling is simplified.

Erfindungsgemäß wird die Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch das schwenkbare Verschlussformteil, dessen freies Ende zur Lagefixierung des Zwischenstückes gegenüber den beiden festen Stangenstücken ausgebildet ist, ergibt sich in einfacher Weise eine verschleißresistente und gut händelbare Längenverstellung der Stangenanordnung. Eine nach dem Stand der Technik vorgesehene Vorspannung des Verriegelungselementes, der während des Längenverstellprozesses durch Kraftanstrengung entgegengewirkt werden muss, entfällt. Dadurch ist ohne größere Kraftanstrengung eine sehr feinfühlige Längenverstellung möglich. Nach dem Verstellvorgang muss das Verschlussformteil nur noch vom Monteur in einem abschließenden Handgriff in die Verriegelungsposition geschwenkt werden. Die Sicherheitsfunktion, die nach dem Stand der Technik durch die Vorspannung der Schiebehülse erreicht wird, ist in das Verschlussformteil selbst integriert. Wegen der Gelenkbefestigung des Verschlussformteils an einem der beiden Stangenstücke ist die Lage des Verschlussformteils gegenüber dem Zwischenstück für jede Längeneinstellung der Stangenanordnung vorgegeben. Eine Axialverschiebung des Verriegelungselementes ist im Gegensatz zum Stand der Technik nicht möglich.According to the invention the task with the characterizing Characteristics of claim 1 solved. By the pivotable closure molding, whose free end for fixing the position of Intermediate piece opposite the two fixed rod pieces is formed, resulting in a simple manner a wear-resistant and easy to handle length adjustment Bar arrangement. A provided in the prior art Preload the locking element during the Längenverstellprozesses Counteracted by effort must be deleted. This is without much effort a very sensitive length adjustment possible. To the adjustment process, the closure molding must only from Installer in a final handle in the locking position be panned. The security feature that according to the prior art by the bias of the sliding sleeve is achieved is integrated into the closure molding itself. Because of the hinge attachment of the closure molding on one of the two pieces of bars is the position of the closure molding opposite the spacer for each length adjustment predetermined the rod assembly. An axial displacement of the locking element is in contrast to State of the art not possible.

Um zu verhindern, dass sich das Zwischenstück unter dem Verschlussformteil drehen kann und damit unbeabsichtigt der Abstand zwischen den Stangenstücken verändert werden kann, ist das freie Ende des Verschlussformteils gemäß Anspruch 2 als Klammer ausgebildet, welche eine vorzugsweise sechskantige Außenkontur des Zwischenstücks formschlüssig umgreift.To prevent the intermediate piece under the closure molding can turn and thus unintentionally the distance between the rod pieces can be changed is the free end of the closure molding according to claim 2 as Clamp formed, which is a preferably hexagonal Outer contour of the intermediate piece positively engages around.

Vorzugsweise ist die Klammer gemäß Anspruch 3 mit zwei Federarmen versehen, welche einander zugewandte aufspreizbare Festhalteenden aufweisen.Preferably, the clip according to claim 3 with two spring arms provided, which facing each other aufspreizbare Retainers have.

Die Erfindung wird nachfolgend anhand figürlicher Darstellungen näher erläutert. Es zeigen:

Die in Figur 1 dargestellte Zungenprüferanordnung besteht im Wesentlichen aus einem ersten Stangenstück 1, einem axial und drehfest zu diesem angeordneten zweiten Stangenstück 2, einem Zwischenstück 3 zur Abstandseinstellung zwischen den beiden Stangenstücken 1 und 2 sowie einem Verschlussformteil 4 zur Lagefixierung des Zwischenstückes 3 relativ zu dem ersten Stangenstück 1. Das Zwischenstück 3 ist nach Art einer Überwurfmutter mit den beiden sich gegenüberliegenden Enden 5 und 6 der Stangenstücke 1 und 2 verschraubt. Dazu ist das Zwischenstück 3 mit einem Rechtsgewinde 7 und einem Linksgewinde 8 ausgestattet. Das Verschlussformteil 4 ist über ein radiales Gelenk 9 an dem Stangenstück 1 schwenkbar befestigt. In Figur 1 ist das Verschlussformteil 4 in verriegelter Schwenklage dargestellt, wobei eine Klammer 10 am freien Ende des Verschlussformteils 4 die vorzugsweise sechskantige Außenkontur des Zwischenstücks 3 formschlüssig umgreift. Die eingestellte Länge x ist somit gesichert, da die Klammer 10 verhindert, dass das Zwischenstück 3 durch Erschütterungen oder andere mechanische Einflüsse unbeabsichtigt verdreht werden kann. Um eine andere Länge, beispielsweise x - δ einzustellen, wird das Verschlussformteil 4, wie in Figur 2 dargestellt, von der Klammerhalterung weggeschwenkt. Der Schwenkwinkel kann beispielsweise 90° betragen. Durch Drehung des Zwischenstücks 3 in einer bestimmten Richtung werden die Enden 5 und 6 der Stangenstücke 1 und 2 mit Hilfe des Linksgewindes 8 und des Rechtsgewindes 7 des Zwischenstückes dichter aneinander herangezogen. Die neue Länge x - δ bei zurückgeschwenkten Verschlussformteil veranschaulicht Figur 3. Das Zurückschwenken des Verschlussformteils 4 bewirkt quasi ein Einrasten der Klammer 10 des Verschlussformteils 4 in Umklammerung der sechskantigen Außenkontur des Zwischenstücks 3. Wie Figur 4 zeigt, ist die Klammer 10 dazu mit zwei Federarmen 11 und 12 ausgestattet, welche mittels aufspreizbarer Festhalteenden 13 und 14 das Zwischenstück 3 drehsicher fixieren.The tongue checker assembly shown in Figure 1 consists in Essentially from a first rod piece 1, an axial and rotatably to this arranged second rod piece 2, a Intermediate piece 3 for distance adjustment between the two Rod pieces 1 and 2 and a closure molding 4 for Positional fixing of the intermediate piece 3 relative to the first Rod piece 1. The intermediate piece 3 is like a union nut with the two opposite ends 5 and 6 of the rod pieces 1 and 2 bolted. This is the intermediate piece 3 with a right-hand thread 7 and a left-hand thread 8 equipped. The closure mold part 4 is via a radial Joint 9 pivotally attached to the rod piece 1. In Figure 1 is the closure molding 4 in locked pivoting position shown, wherein a bracket 10 at the free end of Closure molding 4, preferably hexagonal outer contour of the intermediate piece 3 engages positively. The set Length x is thus secured because the clip 10 prevents that the intermediate piece 3 by vibrations or other mechanical influences are unintentionally twisted can. To set a different length, for example x - δ, is the closure molding 4, as shown in Figure 2, pivoted away from the clip holder. The swivel angle can be for example 90 °. By turning the Intermediate piece 3 in a certain direction become the ends 5 and 6 of the rod pieces 1 and 2 by means of the left-hand thread 8 and the right-hand thread 7 of the intermediate piece denser used together. The new length x - δ when swung back Closure molding illustrated Figure 3. The Swiveling back of the closure molding 4 causes a quasi Engaging the clip 10 of the closure molding 4 in Umklammerung the hexagonal outer contour of the intermediate piece. 3 As FIG. 4 shows, the clamp 10 is provided with two spring arms Equipped 11 and 12, which by means of expandable Retaining ends 13 and 14 fix the spacer 3 against rotation.

Die Erfindung beschränkt sich nicht auf das vorstehend dargestellte Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten Denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen.The invention is not limited to the one shown above Embodiment. Rather, it is a number of variants Conceivable, which also with fundamentally different kind Execution of the features of the invention make use.
