Description

Die Erfindung betrifft eine Räumkette für eine Gleisbaumaschine zum Aushub von Bettungsmaterial eines Gleises, bestehend aus schaufelartigen Räumelementen zum Erfassen und Weiterfördern des Bettungsmaterials sowie die Räumelemente zu einer Endloskette miteinander verbindenden Kettengelenken.The invention relates to a clearing chain for a track construction machine for excavation of bedding material of a track, consisting of shovel-like clearing elements for recording and conveying the bedding material and the Broaching elements to form an endless chain connecting chain links.

Eine derartige gelenkige Räumkette ist bereits durch US 4 614 238 bekannt, wobei die Räumkette aus einer Vielzahl von gleichartig ausgebildeten und jeweils durch das Kettengelenk miteinander verbundenen Kettenelementen zusammengesetzt ist. Die Kettengelenke sind als allseitig bewegbare Kreuzgelenke ausgebildet. Jedes dritte Kettenelement ist mit einem zur Aufnahme von Schüttgut dienenden Räumelement verschraubt. Eine derartige konstruktiv jedoch relativ aufwendige Räumkette kann in vorteilhafter Weise dreidimensional geführt werden.Such an articulated clearing chain is already known from US 4,614,238. wherein the clearing chain from a variety of similarly designed and each chain elements connected by the chain link is composed. The chain links are universal joints that can be moved on all sides educated. Every third chain element is fitted with one screwed of bulk material serving clearing element. Such a constructive however, relatively complex clearing chain can advantageously be three-dimensional be performed.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Räumkette der gattungsgemäßen Art, bei der unter Beibehaltung allseitig bewegbarer Gelenke der konstruktive Aufwand reduzierbar ist.The object of the present invention is now to create a Clearing chain of the generic type, with all sides being retained Movable joints the design effort can be reduced.

Erfindungsgemäß wird diese Aufgabe mit einer Räumkette der eingangs genannten Art dadurch gelöst, daß jeweils zwischen zwei benachbarten Räumelementen ein Kettenzwischenteil mit zwei in Kettenlängsrichtung voneinander distanzierten Kettengelenken angeordnet ist, die jeweils zur gelenkigen Aufnahme eines mit einem Räumelement lösbar verbundenen Gelenkbolzens ausgebildet sind. According to the invention, this object is achieved with a clearing chain of the type mentioned at the beginning Art solved in that between two adjacent clearing elements a chain intermediate part with two in the longitudinal direction of the chain spaced chain links is arranged, each for articulated Inclusion of a hinge pin detachably connected to a clearing element are trained.

Bereits durch die alternierende Zusammensetzung der Räumkette aus Räumelementen einerseits und Kettenzwischenteilen andererseits ergibt sich eine Vereinfachung der Räumkette. Ein weiterer diesbezüglicher Vorteil ist darin zu sehen, daß die Räumelemente selbst ohne jedwede Gelenkteile vereinfacht und damit für den robusten Einsatz besonders geeignet gefertigt werden können.Already from the alternating composition of the clearing chain Broaching elements on the one hand and intermediate chain parts on the other hand result a simplification of the clearing chain. Another advantage in this regard is to be seen in the fact that the clearing elements are simplified even without any joint parts and thus manufactured especially suitable for robust use can be.

Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantages and developments of the invention result from the subclaims.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.In the following the invention with reference to one shown in the drawing Embodiment described in more detail.
