Abstract

The clearing chain has a transverse guide (9) connected to longitudinal guides (12) via guide joints (10). The guides form a channel with upper and lower slide paths (17) and a connecting end slide face (18). The slide end face of the transverse guide is curved towards the guide joint so that an acute angle is enclosed with an extension of the slide end of the longitudinal guide. Deflection of the chain is by contact between chain and end slide face only.

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 one 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, such are already endless trained, around the track around rotating Räumketten known. These consist essentially of one with the track bedding in contact standing transverse guide and two hinged with this longitudinal guides together. Coaxially to the hinge axis, a pulley is positioned in each case, by which the clearing chain is deflected by at least 90 °. The articulated connection of transverse and longitudinal guidance is necessary insofar as thus the possibility of a slight shift of the clearing chain exists relative to the track. Thus, in spatially e.g. through a platform to work better in restricted sections. Also allows the hinge joint an extension of the transverse guide for cleaning a turnout section. As with powerful cleaning machines on the rake chain has a tensile force of about 100 kilonewtons, are the with a sufficient lubrication to be supplied pulleys highest Exposed to loads and frequently 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 the without affecting the articulated Connection allows improved functionality of the clearing chain becomes.

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 with a clearing chain of the aforementioned Type by the features cited in the characterizing part of claim 1 solved.

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.By this combination of features, it is possible, the clearing chain at high loads without affecting the joint only redirect by sliding friction. Due to the special curvature of the Stirngleitbahn is also in case of a larger bend of longitudinal and transverse guidance a trouble-free transfer of the clearing chain on the longitudinal guide guaranteed. Thus, the use of a previously unnecessary from the professional world in conjunction with a joint as an inevitably considered pulley. This is due to the extreme stress highest quality and therefore very expensive form and also with a complex lubricant supply equip.

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.An apparent in Fig. 1 clearing chain 1 is on a machine 2 for cleaning a track bed 3 arranged. The Räumkette 1 is during the work below a raised track 4 as an endless chain arranged around this. This contaminated ballast is 5 to a Screening 6 promoted. The cleaned therein gravel 5 is then already on known manner again introduced into the track 4. The rotation the clearing chain 1 takes place in a plane of rotation 7, which leads to a Bettungsebene 8 is arranged inclined. In labor use of the clearing chain 1 is in one Cut line of the two levels 7,8 a transverse guide 9 is positioned, the extends 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 by guide joints 10 each hinged at a curved end 11 with a longitudinal guide 12 connected. The two longitudinal guides 12 form with the transverse guide 9 a Guide channel 13 (Fig. 5) for storage and management of the clearing chain. 1 As indicated in dash-dotted lines, the transverse guide 9 for a Ballast intake to be extended in a turnout 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 clearing chain 1 is set a plurality of chain links 14 interconnected by chain links 15 together. To guide the Räumkette 1 serves the guide channel 13, consisting of a lower and upper slide 17 and one of these interconnecting Stirngleitbahn 18 composed. 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 is the Transverse guide 9 in the form of a circular arc 19 in the direction of the hinge 10 curved, so that with an extension of the Stirngleitbahn 18 of the Longitudinal guide 12 an acute angle α of preferably about 45 ° included becomes. This creates a curved transverse end 20 of the Stirngleitbahn 18, which comes into contact with the clearing chain 1 only when between the longitudinal and transverse guide 12, 9 takes place an angular change, For example, in the case of an indicated in Fig. 2 extension of the transverse guide 9. The circular arc 19 has a in a hinge axis 21 of the guide joint 10 positioned circle center on.

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 through the adjacent longitudinal guide 12 on the one hand and the hinge axis 21 on the other hand 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 circle 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 Transverse end 20 on a second arc section 24, whose Center of the circle on a rectilinear section 23 parallel, is positioned by the hinge axis 21 leading 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.Due to this special design of the end 20 of the transverse guide 9, the Clearing chain 1 without the aid of a pulley only by sliding friction be redirected. The Räumkette 1 z. B. in a powerful Cleaning machine with a traction of 110 kilonewtons in the through drawn an arrow in Fig. 3 conveying direction.

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 takes place the clearing chain 1 about a deflection roller 27, which is rotatable in the hinge axis 21 is mounted and through an opening of Stirngleitbahn 18 on the sliding plane projects. So that is to be supplied with a lubrication pulley 27 - in particular at a greater bending between longitudinal and Transverse guide 12, 9 - exposed to very high loads. In addition, will the chain pins 14 subjected to extreme stresses.
