Abstract

The invention relates to a sealing profile made of elastomeric material, which profile is fitted with clamping ribs (13, 14) and profiled feet (15, 16), for sealing the gap (area A) between the rail wheel rim side (5) and the rail transition plate (9) at the same level, the sealing profile (11) in the wheel rim area B having an open or closed track gap. The essence of the invention is that a) a stability support (17), which runs continuously in the longitudinal direction of the rail, is arranged between the profiled feet (15, 16), b) the profiled feet (15, 16) and the stability support (17) being seated on a filling profile (18) made of elastomeric material, which profile is situated in some regions between the rail fastenings (6, 7). <IMAGE>

Description

Die Erfindung betrifft eine Spurrillen-Dichtvorrichtung, bestehend aus einem Dichtprofil aus elastomerem Werkstoff, das mit Klemmrippen und Profilfüßen versehen ist, zum Abdichten der Fuge zwischen der Schienenradkranzseite und der niveaugleichen Schienenübergangsplatte (niveaugleiche Verkehrsführung), wobei das Dichtprofil im Randkranzbereich eine offene oder geschlossene Spurrille aufweist (vgl.DE-U-8520 560).The invention relates to a track groove sealing device, consisting of a sealing profile made of elastomeric material, which is provided with clamping ribs and profile feet, for sealing the joint between the rail wheel rim side and the level rail transition plate (level traffic routing), the sealing profile in the rim area an open or closed track groove has (see DE-U-8520 560).

Eine derartige Dichtvorrichtung führt zur Erhöhung der Unfallsicherheit von übergängen sowie Industrie- und Werkstattgleisen, insbesondere im Zweiradverkehr. Je nach Geschwindigkeit des Schienenverkehrs kann ein Dichtprofil eingesetzt werden, das im Radkranzbereich eine offene oder geschlossene Spurrille aufweist.Such a sealing device leads to an increase in the accident safety of crossings and industrial and workshop tracks, particularly in two-wheeled traffic. Depending on the speed of the rail traffic, a sealing profile can be used that has an open or closed track groove in the wheel rim area.

Aus dem deutschen Gebrauchsmuster 8 520 560 ist ein Dichtprofil bekannt, das im wesentlichen die gesamte Fuge ausfüllt, wobei sich zwischen den beiden Füßen die Schienenbefestigung befindet. Dabei ist der schienenzugewandte Profilfuß kürzer als der äußere Profilfuß. Trotz einfacher Montage dieses Dichtprofils und leichter Zugänglichkeit zu der Schienenbefestigung nach Ausbau des Profiles sowie der Tatsache, daß kein Zuschnitt vor Ort notwendig ist, schlägt sich der Verschleiß des Dichtprofils (insbesondere in dessen Kopfbereich) bei Schwerlastverkehr und hoher Geschwindigkeit des Schienenverkehrs besonders nachteilig nieder, was dann zum Austausch des gesamten Profilkörpers führt, was wiederum unwirtschaftlich ist.A sealing profile is known from German utility model 8 520 560, which essentially fills the entire joint, the rail fastening being located between the two feet. The rail-facing profile foot is shorter than the outer profile foot. Despite simple assembly of this sealing profile and easy access to the rail fastening after the profile has been removed, and the fact that no cutting on site is necessary, the wear of the sealing profile (especially in the head region) is particularly disadvantageous in heavy load traffic and high speed of rail traffic, which then leads to the exchange of the entire profile body, which in turn is uneconomical.

Aufgabe der Erfindung ist es daher, eine Spurrillen-Dichtvorrichtung bereitzustellen, die zum einen für den Schwerlastverkehr geeignet ist. Zum anderen soll bei nicht ganz zu verhindernder Verschleißanfälligkeit durch den Radkranz ein eventuell notwendiger Austausch des Dichtprofils lediglich im Oberflächenbereich der abzudichtenden Fuge erfolgen, wobei gleichzeitig die Zugänglichkeit zu den Schienenbefestigungen gewährleistet sein muß. Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1 (Merkmalsgruppen b, c).The object of the invention is therefore to provide a track groove sealing device which is suitable on the one hand for heavy goods traffic. On the other hand, if the wheel rim is not susceptible to wear, it may be necessary to replace the sealing profile only in the surface area of the joint to be sealed, while at the same time access to the rail fastenings must be guaranteed. This problem is solved by the characterizing part of claim 1 (feature groups b, c).

Der zwischen den Profilfüßen in Schienenlängsrichtung durchgehend verlaufende Festigkeitsträger, dessen durchschnittliche Mindeststärke zweckmäßigerweise 40 mm beträgt, führt in Verbindung mit dem Füllprofil, auf dem dieser Festigkeitsträger aufsitzt, zu einer tragfähigen Gesamtkonstruktion bei Schwerlastverkehr. Der Festigkeitsträger besteht dabei aus Stahl oder biegesteifem Kunststoff, wobei zweckmäßigerweise ein Rohr mit einer Mindestwandstärke von 2 mm eingesetzt wird. Bei Verwendung eines Rohres entspräche dann die oben erwähnte Mindeststärke dem Außendurchmesser des Rohres.The strength member running continuously between the profile feet in the longitudinal direction of the rail, the average minimum thickness of which is expediently 40 mm, in conjunction with the filler profile on which this strength member is seated, leads to a stable overall construction in heavy goods traffic. The strength member consists of steel or rigid plastic, a tube with a minimum wall thickness of 2 mm is expediently used. When using a pipe, the above-mentioned minimum thickness would correspond to the outside diameter of the pipe.

Das Füllprofil weist insbesondere eine Nut auf, in der der Festigkeitsträger (bzw. das Rohr) unter gleichzeitiger Verankerung aufsitzt. Dabei sollte die maximale Tiefe der Nut ≦ die Hälfte der Festigkeitsträgerstärke (bzw. des Außendurchmessers des Rohres) betragen. Ferner sollte das Füllprofil beidseitig Erhebungen aufweisen, wobei zwischen diesen Erhebungen und dem Festigkeitsträger (bzw. dem Rohr) die Profilfüße eingeklemmt sind. Durch diese Gesamtmaßnahmen ist eine stabile Verankerung des Dichtprofils gewährleistet, ohne daß die leichte Austauschbarkeit beeinträchtigt wird.The filler profile has, in particular, a groove in which the reinforcement (or the tube) is seated while being anchored. The maximum depth of the groove ≦ should be half the strength of the reinforcement (or the outside diameter of the pipe). Furthermore, the filler profile should have elevations on both sides, the profile feet being clamped between these elevations and the reinforcement (or the tube). These overall measures ensure stable anchoring of the sealing profile without impairing the easy interchangeability.

Da sich das Füllprofil lediglich abschnittsweise zwischen den Schienenbefestigungen befindet, ist nach Entfernung des Dichtprofils und des Festigkeitsträgers (bzw. des Rohres) eine leichte Zugänglichkeit zu den Befestigungsteilen (Klammern, Schrauben) gegeben.Since the filling profile is only in sections between the rail fastenings, easy removal of the fastening parts (clamps, screws) is provided after removing the sealing profile and the reinforcement (or pipe).

Zweckmäßigerweise weist das Füllprofil eine schiefe Ebene auf, die in die Schienenübergangsplatte (z.8. Betonplatte) hinein verläuft, womit eine gleichzeitige Zentrierung dieser Schienenübergangsplatte verbunden ist.The filling profile expediently has an inclined plane which runs into the rail transition plate (e.g. 8th concrete plate), which is associated with a simultaneous centering of this rail transition plate.

Das Dichtprofil wie auch das Füllprofil besteht aus einer Kautschukmischung auf Basis Styrol-Butadien-Kautschuk (SBR), Polychloropren (CR), Ethylen-Propylen-Dien-Mischpolymerisat (EPDM), Nitrilkautschuk (NBR), Silikonkautschuk oder anderen quell-, witterungs- und chemikalienbeständigen Kautschuktypen. Die folgende Tabelle vermittelt nun einige zweckmäßige Daten für das Dicht- und Füllprofil, wobei für das Füllprofil hinsichtlich i) die entsprechenden Werte des Dichtprofils zugrundegelegt werden können.

Figure imgb0001
The sealing profile as well as the filling profile consists of a rubber mixture based on styrene-butadiene rubber (SBR), polychloroprene (CR), ethylene-propylene-diene copolymer (EPDM), nitrile rubber (NBR), silicone rubber or other swelling, weathering and chemical resistant rubber types. The following table provides some useful data for the sealing and filling profile, whereby the corresponding values of the sealing profile can be used as a basis for the filling profile with regard to i).
