Description

Die Erfindung betrifft eine Maschine zur Aufnahme von auf einem Gleis liegendem Schüttgut, insbesondere Schotter, mit einer in Rotation versetzbaren, unmittelbar über dem Gleis zwischen Schienen positionierten, endlosen Räumkette einer höhenverstellbar mit einem Maschinenrahmen verbundenen Schüttgutaufnahmevorrichtung, der ein Aufnahmeende einer in Maschinenlängsrichtung verlaufenden Fördereinrichtung zugeordnet ist.The invention relates to a machine for receiving lying on a track bulk material, in particular ballast, with a rotatable, positioned directly above the track between rails, endless Räumkette a vertically adjustable connected to a machine frame bulk material receiving device associated with a receiving end of a running in the machine longitudinal direction conveyor is.

Eine derartige Maschine ist bereits durch US 5 513452 bekannt, wobei die Schüttgutaufnahmevorrichtung auf einem in Arbeitsrichtung vorgeordneten Fahrzeug vorgesehen ist, dem eine Schotterbett-Reinigungsmaschine nachgeordnet ist. Diese ist mit einer um das Gleis herumgeführten Räumkette zur Schotteraufnahme sowie einem Förderband zum Transport des Schotters in eine Siebanlage ausgestattet.Such a machine is already known from US 5 513 452, wherein the bulk material receiving device is provided on an upstream in the direction of the vehicle, which is arranged downstream of a ballast bed cleaning machine. It is equipped with a roundabout track for ballast picking around the track and a conveyor belt for transporting the ballast into a screening plant.

Durch die Schüttgutaufnahmevorrichtung wird auf dem Gleis zwischengelagerter, neuer Schotter aufgenommen und durch ein nachgeordnetes Förderband über das unter dem Gleis befindliche Ouerkettentrum der Räumkette transportiert und auf das freigelegte Erdplanum abgeworfen. Zusätzlich wird noch durch die Siebanlage gereinigter Schotter abgeworfen. Damit besteht die Möglichkeit, unter Vereinfachung der Transportlogistik neuen Schotter auf dem Gleis vorzulagern, um diesen zur bedarfsweisen Ergänzung dem gereinigten Bettungsschotter zuzuführen.By the bulk material picking device, stored on the track, new gravel is taken and transported by a downstream conveyor belt located above the track Ouerkettentrum the clearing chain and dropped onto the uncovered Erdplanum. In addition, cleaned by the sieve cleaned gravel. This makes it possible, while simplifying transport logistics, to store new ballast on the track in order to supply it to the cleaned bedding ballast as needed.

Gemäß US 5 090 483 ist auch noch eine aus zwei in Arbeitsrichtung unmittelbar hintereinander angeordneten Reinigungsmaschinen zusammengesetzte, gleisverfahrbare Anlage bekannt. Die vorgeordnete Reinigungsmaschine weist zwei in Maschinenquerrichtung voneinander distanzierte, in Maschinenlängsrichtung drehbare Räumketten zur Aufnahme des verschmutzten Schotters aus dem Flankenbereich des Gleises auf. Nach der Reinigung in einer nachgeordneten Siebanlage wird der gereinigte Schotter zwischen den Schienen auf das Gleis abgeworfen und damit zwischengelagert.According to US Pat. No. 5,090,483, a track-mobile installation composed of two cleaning machines arranged directly behind one another in the direction of work is also known. The upstream cleaning machine has two spaced apart in the cross-machine direction, rotatable in the machine longitudinal direction Räumketten for receiving the soiled ballast from the flank region of the track. After cleaning in a downstream screen, the cleaned gravel is dropped between the rails on the track and stored with it.

Die nachgeordnete Reinigungsmaschine ist mit einer endlosen, um das Gleis herumgeführten Räumkette mit einem unterhalb des Gleises zur Schotteraufnahme positionierten Querkettentrum ausgestattet. Oberhalb dieses Querkettentrums befindet sich eine unmittelbar oberhalb der Schwellen positionierte Brücke, der eine rotierbare Kehrbürste vorgeordnet ist. Mit dieser wird der zwischengelagerte, gereinigte Schotter geringfügig von den Schwellen abgehoben und auf die genannte Brücke transferiert. Die Brücke selbst ist im wesentlichen durch ein in Maschinenlängsrichtung verlaufendes Förderband gebildet, mit dem schließlich der gereinigte Schotter unter Überbrückung des genannten Querkettentrums der Räumkette auf das freigelegte Erdplanum abgeworfen wird. Mit einer derartigen Anlage kann die Reinigungsleistung unter Einbeziehung von insgesamt drei Räumketten und zwei Siebanlagen bedeutend gesteigert werden.The downstream cleaning machine is equipped with an endless, guided around the track clearing chain with a positioned below the track for ballast pickup transverse chain center. Above this cross-chain center is a bridge positioned immediately above the threshold, which is preceded by a rotatable sweeping brush. With this, the interposed, cleaned gravel is slightly lifted off the thresholds and transferred to said bridge. The bridge itself is essentially formed by a conveyor belt extending in the machine longitudinal direction, with which finally the cleaned gravel is dropped onto the uncovered earth plane by bridging the said transverse chain center of the clearing chain. With such a system, the cleaning performance can be significantly increased by including a total of three clearing chains and two screening plants.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der gattungsgemäßen Art, mit der auf dem Gleis vorgelagerter Schotter wirksamer aufnehmbar ist.The object of the present invention is now to provide a machine of the generic type, with the on-track ballast more effectively absorbable.

Diese Aufgabe wird erfindungsgemäß mit einer Maschine der gattungsgemäßen Art durch die im Anspruch 1 angeführten Erfindungsmerkmale gelöst.This object is achieved with a machine of the generic type by the features set out in claim 1 invention.

Durch die Kombination mit einer Kehrbürste und einer dieser zugeordneten Fördereinrichtung ist auch der vorgelagerte und von der Schüttgutaufnahmevorrichtung nicht erfaßbare, unmittelbar auf den Schwellen bzw. dazwischenliegende Schotter wiederverwendbar. Damit läßt sich in vorteilhafter Weise der vorgelagerte Schotter mit relativ geringem konstruktiven Aufwand zu 100% wiederum in den Verfahrensprozess einer kompletten Erneuerung der Schotterbettung einbeziehen.The combination with a sweeping brush and a conveyor associated therewith also the upstream and can not be detected by the bulk material receiving device, directly on the sleepers or intervening gravel reusable. This can be included in an advantageous manner, the upstream ballast with relatively little design effort to 100% turn in the process of a complete renewal of ballast bedding.
