Description

Die Erfindung betrifft ein Verfahren für ein abschnittweises Sanieren eines Schienen, Schwellen und ursprüngliche Schienenbefestigungsmittel aufweisenden Gleises, wobei eine Gruppe von benachbarten Schwellen in einer Schienenlängsrichtung derart verschoben wird, dass eine Baulücke zur Durchführung von Schwellen und/oder für eine ungehinderte Schotterreinigung entsteht.The invention relates to a method for a partial renovation of a track having rails, sleepers and original rail fastening means, a group of adjacent sleepers being shifted in a longitudinal direction of the rails in such a way that a gap is created for the implementation of sleepers and / or for unhindered ballast cleaning.

Durch WO 2012/095152 A1 ist ein Verfahren für ein abschnittweises Sanieren eines Gleises bekannt, wobei eine Gruppe von benachbarten Schwellen in einer Schienenlängsrichtung derart verschoben wird, dass damit eine Baulücke zur Durchführung von Schwellen und/oder für eine ungehinderte Schotterreinigung entsteht.By WO 2012/095152 A1 a method for rehabilitating a track in sections is known, a group of adjacent sleepers being displaced in a longitudinal direction of the rails in such a way that a gap is created for the implementation of sleepers and / or for unhindered ballast cleaning.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens der eingangs genannten Art, mit dem eine Vereinfachung einer abschnittweisen Gleissanierung möglich ist.The object of the present invention is to create a method of the type mentioned at the outset with which a simplification of track renovation in sections is possible.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren der gattungsgemäßen Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.This object is achieved according to the invention with a method of the generic type by the features cited in the characterizing part of claim 1.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention emerge from the dependent claims and the description of the drawings.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 eine Ansicht in einer Schienenlängsrichtung von zwei eine Schwelle mit einer Schiene verbindenden Schienenbefestigungsmittel, Fig. 2 eine Draufsicht auf beide Schienenbefestigungsmittel, und Fig. 3, 4 je eine vereinfachte Seitenansicht eines Gleises.The invention is described in more detail below using an exemplary embodiment shown in the drawing. Show it: Fig. 1 a view in a rail longitudinal direction of two rail fastening means connecting a sleeper to a rail, Fig. 2 a plan view of both rail fasteners, and Fig. 3, 4 each a simplified side view of a track.

Eine in Fig. 1 und 2 ersichtliche Schwelle 1 ist durch speziell ausgebildete Schienenbefestigungsmittel 2 mit einer Schiene 3 verbunden. Der Einfachheit halber ist hier lediglich eine Schiene 2 eines Gleises 4 dargestellt. Die nicht dargestellte zweite Schiene 2 des Gleises 4 ist ebenfalls durch zwei derartige Schienenbefestigungsmittel 2 mit der Schwelle 1 verbunden.One in Figs. 1 and 2 The apparent threshold 1 is connected to a rail 3 by specially designed rail fastening means 2. For the sake of simplicity, only one rail 2 of a track 4 is shown here. The second rail 2, not shown, of the track 4 is also connected to the sleeper 1 by two such rail fastening means 2.

Jedes Schienenbefestigungsmittel 2 besteht aus einer Schraubverbindung 5 zur Befestigung eines durch ein Kontaktelement 6 einen Schienenfuß 7 der Schiene 3 kontaktierenden Verbindungsgliedes 8 an der Schwelle1. Das Kontaktelement 6 des Verbindungsgliedes 8 ist als um eine Achse 9 drehbarer Rollkörper 10 zum Abrollen auf der Schiene 3 in einer Schienenlängsrichtung 11 ausgebildet. Die Schraubverbindung 5 ist in einer Bohrung der Schwelle 1 verankert, die üblicherweise zur Befestigung einer der vielen bekannten Schienenbefestigungen dient.Each rail fastening means 2 consists of a screw connection 5 for fastening a connecting member 8, which makes contact with a rail foot 7 of the rail 3 through a contact element 6, on the sleeper 1. The The contact element 6 of the connecting member 8 is designed as a roller body 10 rotatable about an axis 9 for rolling on the rail 3 in a rail longitudinal direction 11. The screw connection 5 is anchored in a bore in the sleeper 1, which is usually used to fasten one of the many known rail fastenings.

Wie insbesondere in Fig. 2 ersichtlich, ist ein für eine Position oberhalb des Schienenfußes 7 vorgesehenes freies Ende 12 des Verbindungsgliedes 8 mittig zwischen zwei zum Abrollen am Schienenfuß 7 vorgesehenen Rollkörpern 10 angeordnet. Am freien Ende 12 des Verbindungsgliedes 8 ist eine Klemmeinrichtung 13 zur Herstellung einer kraftschlüssigen Verbindung zwischen Verbindungsglied 8 und Schienenfuß 7 angeordnet. Die hier beispielhaft als Schraube ausgeführt Klemmeinrichtung 13 könnte auch als Exzenter oder dgl. ausgebildet sein.As in particular in Fig. 2 As can be seen, a free end 12 of the connecting link 8 provided for a position above the rail foot 7 is arranged centrally between two rolling elements 10 provided for rolling on the rail foot 7. At the free end 12 of the connecting link 8 there is a clamping device 13 for producing a non-positive connection between the connecting link 8 and the rail foot 7. The clamping device 13 embodied here as a screw, for example, could also be configured as an eccentric or the like.

Wie in Fig. 3 und 4 dargestellt, sind die jeweils einer Schiene 3 zugeordneten Schienenbefestigungsmittel 2 einer Gruppe von benachbarten Schwellen 1 durch ein längenveränderbares Verbindungselement 14, vorzugsweise eine Kette, miteinander verbunden. Eine Länge I des zwischen Schienenbefestigungsmittel 2 zweier benachbarter Schwellen 1 angeordneten Verbindungselementes 14 ist einem Schwellenabstand des Gleises 4 entsprechend ausgebildet. Das Verbindungselement 14 könnte alternativ beispielsweise auch teleskopartig verlängerbar ausgebildet sein.As in Figures 3 and 4 As shown, the rail fastening means 2 of a group of adjacent sleepers 1 assigned to each rail 3 are connected to one another by a variable-length connecting element 14, preferably a chain. A length I of the connecting element 14 arranged between the rail fastening means 2 of two adjacent sleepers 1 is designed to correspond to a sleeper spacing of the track 4. The connecting element 14 could alternatively, for example, also be designed such that it can be extended telescopically.

Für ein abschnittweises Sanieren des Gleises 4 wird eine Gruppe von benachbarten Schwellen 1 in Schienenlängsrichtung 11 derart verschoben, dass eine Baulücke 15 zur Durchführung von Schwellen 1 und/oder für eine ungehinderte Schotterreinigung entsteht (s. Fig. 3). Für eine vereinfachte Verschiebung der Schwellen 1 relativ zu beiden Schienen 3 werden die ursprünglichen Schienenbefestigungsmittel entfernt und hilfsweise durch die in Fig. 1 und 2. beschriebenen Schienenbefestigungsmittel 2 ersetzt. Diese können nunmehr mitsamt der zugeordneten Schwelle 1 sehr einfach durch eine Arbeitskraft per Hand auf den Schienen 3 in deren Längsrichtung abgerollt bzw. verschoben werden, um damit die zur Gleissanierung erforderliche Baulücke 15 zu schaffen (s. Fig. 4). Die Schwelle 1 kann nach deren Verschiebung wahlweise durch Betätigung der als Schraube ausgebildeten Klemmeinrichtung 13 kraftschlüssig mit den Schienen 3 verbunden werden, um damit ein weiteres, unbeabsichtigtes Verschieben zuverlässig zu verhindern.To rehabilitate the track 4 in sections, a group of adjacent sleepers 1 is shifted in the longitudinal direction 11 of the rails in such a way that a gap 15 is created for the implementation of sleepers 1 and / or for unhindered ballast cleaning (see Fig. Fig. 3 ). For a simplified displacement of the sleepers 1 relative to the two rails 3, the original rail fastening means are removed and alternatively replaced by the in Figs. 1 and 2 . described rail fastening means 2 replaced. These can now, together with the associated sleeper 1, very easily be unrolled or shifted by hand on the rails 3 in their longitudinal direction in order to create the vacant lot 15 required for the track renovation (see Fig. Fig. 4 ). After it has been moved, the sleeper 1 can optionally be positively connected to the rails 3 by actuating the clamping device 13 designed as a screw, in order to reliably prevent further, unintentional movement.

Da infolge intensiv befahrener Gleise 4 nur kurze Zeitfenster für eine Gleissanierung zur Verfügung stehen, werden in einer hier beispielhaft angeführten Einsatzmöglichkeit die mit den erfindungsgemäßen Schienenbefestigungsmittel 2 verbundenen Schwellen 1 - nach Reinigung des in der Baulücke 15 gelagerten Schotters - wiederum in ihre Ausgangsposition zurück verschoben (s. Fig. 4). Erst am darauffolgenden Tag erfolgt in einer weiteren Sanierungsetappe eine Erneuerung der Schwellen 1, wobei wiederum - wie bereits erwähnt - durch Verschieben einer Gruppe von Schwellen 1 die nunmehr für eine Schwellendurchführung erforderliche Baulücke 15 geschaffen wird.Since there are only short time windows available for track renovation due to the busy track 4, the sleepers 1 connected to the rail fastening means 2 according to the invention - after cleaning the ballast stored in the construction gap 15 - are again moved back to their starting position ( s. Fig. 4 ). The sleepers 1 are not renewed until the next day in a further refurbishment phase, whereby - as already mentioned - the gap 15 now required for a sleeper implementation is created by moving a group of sleepers 1.

Für das genannte Rückverschieben der Schwellen 1 ist es von besonderem Vorteil, wenn zwei benachbarte Schwellen 1 jeweils durch ein vorzugsweise als Kette ausgebildetes Verbindungselement 14 gekoppelt sind. Es muss daher lediglich die an die Baulücke 15 angrenzende Schwelle 1 erfasst und in deren ursprüngliche Position zurück verschoben werden. Da der Rollwiderstand infolge der Rollkörper 10 sehr gering ist, kann diese Verschiebung problemlos durch eine Arbeitskraft händisch ausgeführt werden. Die angrenzenden, durch die Verbindungselemente 14 miteinander verbunden Schwellen 1 der Gruppe werden automatisch in ihre jeweilige ursprüngliche Position mitgezogen. Infolge der auf einen Schwellenabstand bestimmten Länge I jedes Verbindungselementes 14 ist sichergestellt, dass mit der Rückverschiebung der Schwellen 1 automatisch auch der richtige Schwellenabstand vorliegt. For the aforementioned backward displacement of the sleepers 1, it is particularly advantageous if two adjacent sleepers 1 are each coupled by a connecting element 14, which is preferably designed as a chain. It is therefore only necessary to grasp the threshold 1 adjoining the construction gap 15 and move it back into its original position. Since the rolling resistance is very low as a result of the rolling elements 10, this shift can easily be carried out manually by a worker. The adjacent thresholds 1 of the group connected to one another by the connecting elements 14 are automatically drawn into their respective original position. As a result of the length I of each connecting element 14, which is determined to be a threshold distance, it is ensured that the correct threshold distance is automatically present when the thresholds 1 are shifted back.
