Description

Die Erfindung betrifft eine Räumkette zum Transport von Schotter einer Gleisbettung gemäß den im Oberbegriff von Anspruch 1 angeführten Merkmalen.The invention relates to a clearing chain for the transport of ballast of a track bed according to the features cited in the preamble of claim 1.

Durch US 4 614 238, US 4 014 389, DE 3 151 652, sind bereits derartige endlos ausgebildete, um das Gleis herum rotierende Räumketten bekannt. Diese setzen sich im wesentlichen aus einer mit der Gleisbettung in Kontakt stehenden Querführung und zwei mit dieser gelenkig verbundenen Längsführungen zusammen. Koaxial zur Gelenkachse ist jeweils eine Umlenkrolle positioniert, durch die die Räumkette um wenigstens 90° umgelenkt wird. Die gelenkige Verbindung von Quer- und Längsführung ist insofern notwendig, als damit die Möglichkeit einer geringfügigen Verschiebung der Räumkette relativ zum Gleis besteht. Damit kann in räumlich z.B. durch einen Bahnsteig eingeschränkten Abschnitten besser gearbeitet werden. Außerdem ermöglicht die Gelenkverbindung eine Verlängerung der Querführung zum Reinigen eines Weichenabschnittes. Da bei leistungsfähigen Reinigungsmaschinen auf die Räumkette eine Zugkraft von etwa 100 Kilonewton einwirkt, sind die mit einer ausreichenden Schmierung zu versorgenden Umlenkrollen höchsten Belastungen ausgesetzt und häufig zu erneuern.By US 4 614 238, US 4 014 389, DE 3 151 652, already such endless trained, around the track rotating Räumketten are known. These are essentially composed of a transverse guide which is in contact with the track bedding and two longitudinal guides which are articulated to it. Coaxially to the hinge axis, a pulley is positioned, by which the clearing chain is deflected by at least 90 °. The articulated connection of transverse and longitudinal guide is necessary insofar as there is the possibility of a slight displacement of the clearing chain relative to the track. Thus, in spatially e.g. worked through a platform restricted sections work better. In addition, the hinge connection allows extension of the transverse guide for cleaning a switch section. Since powerful cleaning machines have a pulling force of about 100 kilonewtons on the reaming chain, the deflection rollers to be supplied with sufficient lubrication are subjected to the highest loads and are often renewed.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Räumkette der gattungsgemäßen Art, mit der ohne Beeinträchtigung der gelenkigen Verbindung eine verbesserte Funktionsfähigkeit der Räumkette ermöglicht wird.The object of the present invention is now to provide a clearing chain of the generic type, with an improved functionality of the clearing chain is made possible without affecting the articulated connection.

Erfindungsgemäß wird diese Aufgabe mit einer Räumkette der eingangs genannten Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.According to the invention this object is achieved by a clearing chain of the type mentioned by the features cited in the characterizing part of claim 1.

Durch diese Merkmalskombination ist es möglich, die Räumkette auch bei hohen Belastungen ohne Beeinträchtigung der Gelenkverbindung lediglich durch Gleitreibung umzulenken. Durch die spezielle Krümmung der Stirngleitbahn ist auch im Falle einer größeren Abwinkelung von Längs- und Querführung eine problemlose Überführung der Räumkette auf die Längsführung gewährleistet. Damit erübrigt sich der Einsatz einer bisher von der Fachwelt in Verbindung mit einem Gelenk als unumgänglich betrachteten Umlenkrolle. Diese ist durch die extreme Belastung hochwertigst und damit sehr teuer auszubilden und außerdem mit einer aufwendigen Schmiermittelversorgung auszustatten.This feature combination makes it possible to redirect the clearing chain even at high loads without affecting the joint only by sliding friction. Due to the special curvature of the Stirngleitbahn a trouble-free transfer of the clearing chain is ensured on the longitudinal guide even in the case of a larger bend of longitudinal and transverse guidance. Thus, the use of a previously considered by the professional world in connection with a joint deflection roller is unnecessary. This is due to the extreme stress highest quality and thus very expensive form and also equipped with a complex lubricant supply.

Eine in Fig. 1 ersichtliche Räumkette 1 ist an einer Maschine 2 zur Reinigung einer Gleisbettung 3 angeordnet. Die Räumkette 1 ist während des Arbeitseinsatzes unterhalb eines angehobenen Gleises 4 als Endloskette um dieses herumgeführt angeordnet. Dabei wird verunreinigter Schotter 5 zu einer Siebanlage 6 gefördert. Der darin gereinigte Schotter 5 wird dann auf bereits bekannte Art und Weise wieder in das Gleis 4 eingebracht. Die Rotation der Räumkette 1 erfolgt in einer Rotationsebene 7, die zu einer Bettungsebene 8 geneigt angeordnet ist. Im Arbeitseinsatz der Räumkette 1 ist in einer Schnittlinie der beiden Ebenen 7,8 eine Querführung 9 positioniert, die sich quer über die Gleisbettung 3 erstreckt.A clearing chain 1 shown in FIG. 1 is arranged on a machine 2 for cleaning a track bed 3. The broaching 1 is during work under a raised track 4 as an endless chain order arranged around this. In this case, contaminated ballast 5 is conveyed to a screening plant 6. The gravel 5 cleaned therein is then reintroduced into the track 4 in a manner already known. The rotation of the clearing chain 1 takes place in a plane of rotation 7, which is arranged inclined to a Bettungsebene 8. In the working use of the clearing chain 1, a transverse guide 9 is positioned in a section line of the two planes 7, 8, which extends transversely across the track bed 3.

Wie in Fig. 2 ersichtlich, ist die Querführung 9 durch Führungsgelenke 10 jeweils an einem gekrümmten Ende 11 mit einer Längsführung 12 gelenkig verbunden. Die beiden Längsführungen 12 bilden mit der Querführung 9 einen Führungskanal 13 (Fig. 5) zur Lagerung und Führung der Räumkette 1. Wie in strichpunktierten Linien angedeutet, kann die Querführung 9 für eine Schotteraufnahme in einem Weichenabschnitt verlängert werden.As can be seen in FIG. 2, the transverse guide 9 is articulated by guide joints 10 at a respective curved end 11 to a longitudinal guide 12. The two longitudinal guides 12 form with the transverse guide 9 a guide channel 13 (FIG. 5) for the storage and guidance of the clearing chain 1. As indicated by dotted lines, the transverse guide 9 can be extended for a ballast receiving in a switch section.

Wie insbesondere in Fig. 3 und 5 ersichtlich, setzt sich die Räumkette 1 aus einer Vielzahl von durch Kettenbolzen 14 miteinander verbundenen Kettengliedern 15 zusammen. Zur Führung der Räumkette 1 dient der Führungskanal 13, der sich aus einer unteren und oberen Gleitbahn 17 sowie einer diese miteinander verbindenden Stirngleitbahn 18 zusammensetzt. Diese verläuft normal zur Rotationsebene 7. Die Gleitbahnen 17,18 sind aus hochverschleißfestem Material und lösbar mit dem Führungskanal 13 verbunden.As can be seen in particular in FIGS. 3 and 5, the broaching chain 1 is composed of a multiplicity of chain links 15 interconnected by chain pins 14. To guide the clearing chain 1 of the guide channel 13, which is composed of a lower and upper slide 17 and a connecting them together Stirngleitbahn 18. This runs normal to the plane of rotation 7. The slides 17,18 are made of highly wear-resistant material and releasably connected to the guide channel 13.

Wie insbesondere in Fig. 3 und 4 ersichtlich, ist die Stirngleitbahn 18 der Querführung 9 in Form eines Kreisbogens 19 in Richtung zum Führungsgelenk 10 gekrümmt, so dass mit einer Verlängerung der Stirngleitbahn 18 der Längsführung 12 ein spitzer Winkel α von vorzugsweise etwa 45° eingeschlossen wird. Damit entsteht ein gekrümmtes Querführungsende 20 der Stirngleitbahn 18, das erst dann mit der Räumkette 1 in Kontakt kommt, wenn zwischen Längs- und Querführung 12, 9 eine Winkelveränderung stattfindet, beispielsweise im Falle einer in Fig. 2 angedeuteten Verlängerung der Querführung 9. Der Kreisbogen 19 weist einen in einer Gelenkachse 21 des Führungsgelenkes 10 positionierten Kreismittelpunkt auf.As can be seen in particular in FIGS. 3 and 4, the Stirngleitbahn 18 of the transverse guide 9 is curved in the form of a circular arc 19 in the direction of the hinge 10, so that an extension of the Stirngleitbahn 18 of the longitudinal guide 12 an acute angle α of preferably about 45 ° included becomes. This results in a curved transverse end 20 of Stirngleitbahn 18, which only comes into contact with the clearing chain 1, when between the longitudinal and transverse guide 12, 9, a change in angle takes place, for example, in the case of an indicated in Fig. 2 extension of the transverse guide 9. The circular arc 19 has a positioned in a hinge axis 21 of the guide joint 10 circle center.

Ein durch die angrenzende Längsführung 12 einerseits und die Gelenkachse 21 andererseits begrenzter, normal zur Stirngleitbahn 18 der Längsführung 12 verlaufender Abstand a ist identisch mit einem Kreisbogenradius r des gekrümmten Querführungsendes 20. Der Kreisbogen 19 bildet ein Kreissegment mit einem Winkel β von 60°. Die Stirngleitbahn 18 weist zwischen einem geradlinigen Abschnitt 23 der Querführung 9 und dem kreisbogenförmigen Querführungsende 20 einen zweiten Kreisbogenabschnitt 24 auf, dessen Kreismittelpunkt auf einer zum geradlinigen Abschnitt 23 parallel verlaufenden, durch die Gelenkachse 21 führenden Geraden 26 positioniert ist.A by the adjacent longitudinal guide 12 on the one hand and the hinge axis 21 on the other limited, normal to Stirngleitbahn 18 of the longitudinal guide 12 extending distance a is identical to a circular arc radius r of the curved transverse end 20. The circular arc 19 forms a circular segment with an angle β of 60 °. The Stirngleitbahn 18 has between a rectilinear portion 23 of the transverse guide 9 and the circular arc-shaped transverse end 20, a second circular arc portion 24, the center of the circle is positioned on a rectilinear portion 23 parallel, passing through the hinge axis 21 straight line 26.

Durch diese spezielle Ausbildung des Endes 20 der Querführung 9 kann die Räumkette 1 ohne Zuhilfenahme einer Umlenkrolle lediglich durch Gleitreibung umgelenkt werden. Die Räumkette 1 wird z. B. bei einer leistungsfähigen Reinigungsmaschine mit einer Zugkraft von 110 Kilonewton in der durch einen Pfeil in Fig. 3 dargestellten Förderrichtung gezogen.By this special design of the end 20 of the transverse guide 9, the clearing chain 1 can be deflected without the aid of a guide roller only by sliding friction. The Räumkette 1 z. B. pulled in a powerful cleaning machine with a tensile force of 110 kilonewtons in the conveying direction shown by an arrow in Fig. 3.

Gemäß einer in Fig. 6 dargestellten bekannten Lösung erfolgt die Umlenkung der Räumkette 1 um eine Umlenkrolle 27, die in der Gelenkachse 21 drehbar gelagert ist und durch eine Öffnung der Stirngleitbahn 18 über deren Gleitebene vorragt. Damit ist die mit einer Schmierung zu versorgende Umlenkrolle 27 - insbesondere bei einer stärkeren Abwinkelung zwischen Längs- und Querführung 12, 9 - sehr hohen Belastungen ausgesetzt. Außerdem werden die Kettenbolzen 14 extremen Beanspruchungen unterworfen.According to a known solution shown in Fig. 6, the deflection of the clearing chain 1 to a guide roller 27 which is rotatably mounted in the hinge axis 21 and protrudes through an opening of the Stirngleitbahn 18 on the sliding plane. Thus, the to be supplied with a lubrication pulley 27 - especially at a greater angle between the longitudinal and transverse guide 12, 9 - exposed to very high loads. In addition, the chain pins 14 are subjected to extreme stresses.
