Description

Die Erfindung bezieht sich auf eine Einrichtung zur Prüfung und Aufarbeitung eines Weichenantriebs für eine Eisenbahnweiche gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for testing and processing a point mechanism for a railway switch according to the preamble of claim 1.

Eine Eisenbahnweiche ermöglicht einem Schienenfahrzeug den Übergang von einem Gleis auf ein anderes Gleis ohne seine Fahrt zu unterbrechen. An einer Spitze der Weiche ist ein Weichenantrieb angebracht, mit dem Weichenzungen gestellt und in ihrer Endlage festgehalten werden. Ein zwischen dem Weichenantrieb und jeder der beiden Weichenzungen eingebauter Weichenverschluss dient einerseits dazu, die anliegende Weichenzunge an einer Backenschiene festzuhalten, um zu verhindern, dass sie durch Spannungen in der Weichenzunge oder von außen einwirkende Kräfte bewegt wird; andererseits dient er dazu, die abliegende Weichenzunge im ausreichenden Abstand zur anderen Backenschiene zu halten. Bei langen Weichen, insbesondere bei Hochgeschwindigkeitsweichen, sind zusätzliche, über die Länge der Weiche verteilte Weichenantriebe mit Verschlüssen erforderlich. Elektrische Weichenantriebe sind mit einer Kupplungsvorrichtung ausgerüstet, die Schäden verhindert, wenn der Umstellwiderstand zu groß wird oder wenn die Bewegung durch Fremdkörper zwischen Weichenzunge und Backenschiene behindert wird.A railway switch allows a rail vehicle to make the transition from one track to another without interrupting its journey. At a tip of the switch a turnout drive is mounted, provided with the switch blades and held in their final position. On the one hand, a switch lock installed between the switch mechanism and each of the two switch blades serves to hold the adjoining switch blade against a stock rail in order to prevent it from being moved by stresses in the switch blade or by external forces; On the other hand, it serves to keep the remote switch blade at a sufficient distance from the other stock rail. Long turnouts, especially high speed turnouts, require additional turnout turnout drives distributed over the length of the turnout. Electric point machines are equipped with a coupling device that prevents damage when the Umstellwiderstand is too large or when the movement is hindered by foreign matter between switch blade and stock rail.

Ein Weichenantrieb kann beispielsweise ein Gehäuse mit Deckel aufweisen, in dem ein Elektromotor mit angeflanschtem Getriebe, Stellschieber mit Verschlusskurve, eine Schalteinrichtung und ein Überwachungsschieber angeordnet sind. Die Drehbewegung des Elektromotors kann über das Getriebe in eine geradlinige Stellbewegung der Stellschieber umgesetzt werden. Von den Stellschiebern werden die Stellstangen angetrieben, die die Stellbewegung auf die Weichenzungen übertragen. Zum Überwachen der Weichenzungenendlagen können die Überwachungsschieber dienen. Zur Stellkraftbegrenzung kann eine einstellbare Getriebekupplung vorgesehen sein.A point machine may, for example, have a housing with a cover, in which an electric motor with a flanged gear, locking slide with closing curve, a switching device and a monitoring slide are arranged. The rotational movement of the electric motor can be implemented via the transmission in a rectilinear adjusting movement of the adjusting slide. The adjusting rods drive the adjusting rods, which transmit the adjusting movement to the switch blades. To monitor the Weichenzungenendlagen the monitoring slide serve. To limit the force can be provided an adjustable transmission clutch.

Gattungsgemäße Weichenantriebe werden beispielsweise in der Produktinformation "Weichenstellsysteme" der Firma Hanning & Kahl, August 2010 , veranschaulicht.Generic point machines are used for example in the Product information "Point control systems" from Hanning & Kahl, August 2010 , illustrated.

Bei Weichenantrieben für Eisenbahnweichen muss in periodischen Zeitabständen überprüft werden, ob diese zu ersetzen sind oder ob sie generalüberholt werden können. Bisher werden die Weichenantriebe vom jeweiligen Einbauort zum Herstellerwerk zur Aufarbeitung und Prüfung zurückgesandt. Damit geht aber ein großer logistischer und zeitlicher Aufwand mit hohen Kosten einher: So müssen Reserveantriebe in ausreichender Zahl Vorort vorrätig gehalten und während der Aufarbeitungszeit ersatzweise eingebaut werden. Ferner müssen die aufzuarbeitenden Weichenantriebe, die ein Gewicht von zum Teil über 100 kg aufweisen können, nicht stapelbar auf Europaletten per Schiff oder Flugzeug hin- und rücktransportiert und dabei jeweils ver- und entzollt werden. Im Herstellerwerk muss die Aufarbeitung unter Berücksichtigung einer Priorisierung der laufenden Fertigung neuer Weichenantriebe erfolgen.For point turnouts for railway turnouts, it is necessary to check at regular intervals whether these are to be replaced or whether they can be overhauled. So far, the point machines from the respective installation site to the factory for processing and testing are returned. However, this involves a great deal of logistical and time-consuming work with high costs. For example, reserve drives must be kept in stock in sufficient numbers and installed as replacement during the refurbishment period. Furthermore, the point machines to be worked up, which may have a weight of more than 100 kg in some cases, can not be stacked on Euro pallets and transported back and forth by ship or plane and thereby in each case locked and unlatched. In the manufacturing plant, the processing must be carried out taking into account a prioritization of the ongoing production of new point machines.

Weichenantriebsprüfstände sind beispielsweise aus der Produktinformation "WAPS - Weichenantriebs Prüfstand" der Firma Hastema GmbH, Januar 2008 und der Produktinformation "PT 10K Kompakt" der Firma probitron GmbH aus September 2008 bekannt.Point drive test stands are for example from Product information "WAPS - Point Drive Test Bench" of Hastema GmbH, January 2008 and the Product information "PT 10K Kompakt" of the company probitron GmbH from September 2008 known.

Die Offenlegungsschrift DE 10 2009 020 182 A1 offenbart einen mobilen Prüfstand zum Prüfen von Bremsen oder Antriebsaggregaten.The publication DE 10 2009 020 182 A1 discloses a mobile test stand for testing brakes or drive assemblies.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannte Art bereitzustellen, mit der eine Aufarbeitung und Prüfung von zu überholenden Weichenantrieben kosten- und zeitoptimiert durchführbar ist.The invention has for its object to provide a device of the type mentioned, with a workup and testing of turnout drives to be overhauled is cost and time feasible feasible.

Die Aufgabe wird erfindungsgemäß gelöst durch eine gattungsgemäße Einrichtung zur Prüfung und Aufarbeitung eines Weichenantriebs für eine Eisenbahnweiche, welche die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale aufweist. Demnach ist der Prüfstand zur mechanischen und elektrischen Prüfung der Funktionstüchtigkeit des Weichenantriebs nach vorgebbaren Prüfanweisungen in einem transportier- und begehbaren Großraumbehälter angeordnet und betreibbar. Durch die Erfindung wird eine mobile Prüf- und Aufarbeitungseinrichtung für Weichenantriebe bereitgestellt, die sämtliche Prüf- und Werkstattmittel aufweist, um eine Aufarbeitung und Prüfung an verschiedenen Einsatzorten durchführen zu können. Hierdurch werden der logistische, zeitliche und kostenmäßige Aufwand für die routinemäßige Generalüberholung von Weichenantrieben für Eisenbahnweichen erheblich reduziert. Ebenso verringert sich die Zeit, die der zu überholende Weichenantrieb von seinem Ausbau bis zu seinem Wiedereinbau ausfällt und durch einen Reserveantrieb ersetzt werden muss. Der umständliche Versand zurück ins Herstellerwerk entfällt, wodurch dort Aufarbeitungsarbeiten von gebrauchten Weichenantrieben nicht eingeplant werden müssen und Ressourcen zur Herstellung neuer Weichenantriebe eingesetzt werden können.The object is achieved by a generic device for testing and reconditioning a points drive for a railway switch, which has the features specified in the characterizing part of claim 1. Accordingly, the test bed for mechanical and electrical testing of the functionality of the points drive is arranged according to specifiable test instructions in a transportable and walk-in large capacity container and operable. The invention provides a mobile testing and reprocessing device for point machines, which has all testing and workshop means to carry out a processing and testing at different locations. This will be the logistical, time and cost overhead for routine overhaul significantly reduced by turnout drives for railway switches. Similarly, reduces the time that the points to overtake point drive from its removal to its replacement and must be replaced by a backup drive. The cumbersome shipping back to the factory is eliminated, which there refurbishment of used turnout drives do not need to be scheduled and resources can be used to produce new points drives.

Damit die erfindungsgemäße Prüf- und Aufarbeitungseinrichtung in Ländern mit unterschiedlichen Landesversorgungsnetzen betrieben werden kann, ist ein Spannungsanpassungsmodul vorgesehen, der die jeweils primärseitige Versorgungsspannung in eine sekundärseitige Betriebsspannung für die Einrichtung umwandeln kann.So that the test and reprocessing device according to the invention can be operated in countries with different state-supply networks, a voltage adjustment module is provided which can convert the respective primary-side supply voltage into a secondary-side operating voltage for the device.

Darüber hinaus weist der Großraumbehälter erfindungsgemäß einen Prüfbereich, in dem der Prüfstand angeordnet ist, und davon abgeteilt einen Werkstattbereich zur Aufarbeitung eines Weichenantriebes auf.

Über die Kuppelstange werden die zu überprüfenden Kräfte in unterschiedlichen Betriebssituationen des Weichenantriebs übertragen. Durch Einsatz eines elektrischen Linearantriebes im Vergleich zu hydraulischen Antrieben kann der Prüfstand vergleichsweise schlank ausgeführt werden, damit dieser in dem Großraumbehälter untergebracht werden kann. Der Linearantrieb bildet die im Betrieb an einer Eisenbahnweiche auftretenden und auf den Weichenantrieb einwirkenden Kräfte nach.In an advantageous embodiment of the test system according to the invention, the test stand has a linear drive for functional testing of various forces. The linear drive has, for example, a movable carriage on which a coupling rod is attached for coupling to a rack of the actuator to be tested.
