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 A, US 4 014 389 A, DE 3 151 652 A, 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 A, US 4 014 389 A, DE 3 151 652 A, such endlessly trained, around the track rotating Räumketten are already 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, unter Verzicht auf Umlenkrollen die Führungsgelenke in bezug auf die Räumkette tiefer zu positionieren. Damit ist der besondere Vorteil erzielbar, dass das Gleis zur Durchführung der Räumkette weniger hoch von der Gleisbettung abgehoben werden muss. Dies führt einerseits zu einer Schonung des Gleises und andererseits kann durch die geringere Gleisanhebung der Fahrwerksabstand der Maschine reduziert werden. Als weiterer besonderer Vorteil können die teuren Umlenkrollen eingespart werden. Durch den Wegfall der Umlenkrollen ist die Umlenkung auch in einem größeren Radius durchführbar, so dass damit die auf die Räumkette einwirkenden Belastungen deutlich reduzierbar sind.By this feature combination, it is possible to lower the guide joints with respect to the clearance chain lower waiving pulleys. Thus, the particular advantage is achieved that the track to carry out the clearing chain must be lifted less high from the track bedding. This leads on the one hand to a protection of the track and on the other hand can be reduced by the lower track elevation of the chassis distance of the machine. As a further advantage, the expensive pulleys can be saved. By eliminating the pulleys, the deflection is carried out in a larger radius, so that thus the loads acting on the clearing chain are significantly reduced.

Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den weiteren Ansprüchen und der Zeichnung.Further advantages and embodiments of the invention will become apparent from the other claims and the drawings.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.In the following the invention will be described in more detail with reference to embodiments shown in the drawing.

  • 2 is a simplified plan view of the excavation chain,
  • 3, 4 are each an enlarged plan view of a deflection of the excavation chain,
  • 5 and 6 a known deflection with a guide roller, and
  • Fig. 7 is a view of a guide joint with a section through a guide channel.

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 Räumkette 1 is during the work arranged underneath a raised track 4 as an endless chain 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 7 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 7, 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. 5 und 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 Längsund Querführung 12, 9 - sehr hohen Belastungen ausgesetzt. Außerdem werden die Kettenbolzen 14 extremen Beanspruchungen unterworfen.According to a known solution shown in FIGS. 5 and 6, the deflection chain 1 is deflected about a deflection roller 27, which is rotatably mounted in the articulation axis 21 and projects through an opening of the Stirngleitbahn 18 on its sliding plane. Thus, the to be supplied with a lubrication guide roller 27 - especially at a greater deflection between the longitudinal and transverse guide 12, 9 - exposed to very high loads. In addition, the chain pins 14 are subjected to extreme stresses.

Wie in Fig. 7 ersichtlich, sind die Führungsgelenke 10 in Richtung zur unteren Gleitbahn 17 des Führungskanals 13 versetzt angeordnet, und zwar derart, dass die Führungsgelenke 10 unterhalb der - bezüglich einer Normalen zur Rotationsebene 7 - mittig durch die Stirngleitbahn 18 geführten Rotationsebene 7 positioniert sind. Durch die tiefere Lage der beiden Führungsgelenke 10 kann das Gleis 4 derart abgesenkt werden, dass eine durch eine strichpunktierte Linie 16 angedeutete Schwellenunterkante unmittelbar über dem Führungsgelenk 10 positioniert ist.As can be seen in Fig. 7, the guide joints 10 are arranged offset in the direction of the lower slide 17 of the guide channel 13, in such a way that the guide joints 10 below the - with respect to a normal to the plane of rotation 7 - centered guided by the Stirngleitbahn 18 rotation plane 7 are. Due to the lower position of the two guide joints 10, the track 4 can be lowered such that a direction indicated by a dotted line 16 threshold lower edge is positioned directly above the hinge joint 10.

Die Gleitbahnen 17,18 sind zumindest im Übergangsbereich von Quer- zur Längsführung 9, 12 lösbar mit dem Führungskanal 13 verbunden und aus hochverschleißfestem Material gebildet. Alternativ könnte das Führungsgelenk 10 auch zur Gänze an einer Unterseite 22 des Führungskanals 13 angeordnet sein.The slides 17,18 are at least in the transition region from transverse to longitudinal guide 9, 12 releasably connected to the guide channel 13 and formed of highly wear-resistant material. Alternatively, the guide joint 10 could also be arranged entirely on an underside 22 of the guide channel 13.
