Abstract
Description
Die Erfindung betrifft eine Gleisbaumaschine zum Unterstopfen und Einschottern eines Gleises, mit einem ersten und einem zweiten, durch eine Gelenkverbindung gelenkig miteinander verbundenen, durch Schienenfahrwerke am Gleis verfahrbaren Maschinenrahmen, wobei dem ersten Maschinenrahmen ein durch Antriebe höhenverstellbares Stopfaggregat sowie ein diesem unmittelbar benachbartes Gleishebe- und Richtaggregat und dem zweiten Maschinenrahmen ein Schotterpflug zum Einschottern des Gleises sowie eine Kehrbürste zugeordnet sind.The invention relates to a track construction machine for tamping and ballasting a track, with a first and a second machine frame, which is articulated by an articulated connection and can be moved by rail bogies on the track, the first machine frame having a tamping unit which is adjustable in height by drives and a track lifting and immediately adjacent thereto Straightening unit and the second machine frame a ballast plow for ballasting the track and a sweeping brush are assigned.
Eine derartige Gleisbaumaschine ist bereits durch die EP 0 436 757 B1 bekannt. Mit Hilfe der Kehrbürste und vorgeordneten Förderbändern kann überschüssiger Schotter zum Stopfaggregat vortransportiert und dort bedarfsweise im Bereich von Stopfpickeln gezielt auf das Gleis abgeworfen werden. Mit dem der Kehrbürste in Arbeitsrichtung unmittelbar vorgeordneten Schotterpflug wird im Zuge der Gleiskorrektur- und Stopfarbeiten gleichzeitig auch eine Reprofilierung der Schotterbettung durchgeführt.Such a track construction machine is already known from EP 0 436 757 B1. With the help of the sweeping brush and upstream conveyor belts, excess ballast can be transported to the tamping unit, where it can be dropped onto the track in the area of tamping picks. With the ballast plow immediately upstream of the sweeping brush in the working direction, a re-profiling of the ballast bedding is carried out at the same time as the track correction and tamping work.
Durch die US 4 165 694 ist eine weitere Gleisbaumaschine zum gleichzeitigen Unterstopfen und Einschottern eines Gleises bekannt, wobei der Schotterpflug am vorderen Ende und die Kehrbürste am hinteren Ende der Maschine vorgesehen ist. Ein mit dem Schotterpflug verbundener, trailerförmiger Maschinenrahmen ist mit Hilfe eines Längsverschiebeantriebes unabhängig von einem weiteren, nachfolgenden und mit den Stopfaggregaten verbundenen Maschinenrahmen kontinuierlich verfahrbar. Mit dieser bekannten Ausführung wurde der Versuch unternommen, die bezüglich ihrer Vorfahrtbewegung unterschiedlichen Technologien des Gleisstopfens und Pflügens zu kombinieren.From US 4 165 694 a further track construction machine for simultaneously tamping and ballasting a track is known, the ballast plow being provided at the front end and the sweeping brush at the rear end of the machine. A trailer-shaped machine frame connected to the ballast plow can be moved continuously with the help of a longitudinal displacement drive independently of a further machine frame that follows and is connected to the tamping units. With this known design an attempt was made to combine the different technologies of track tamping and plowing with regard to their right of way movement.
Die EP 0 397 956 B1 beschreibt eine aus insgesamt drei gelenkig miteinander verbundenen Maschinenrahmen zusammengesetzte Gleisbaumaschine zum gleichzeitigen Unterstopfen und Einschottern eines Gleises, die im Arbeitseinsatz kontinuierlich verfahrbar ist. Unabhängig von dieser kontinuierlichen Vorfahrt wird ein weiterer, trailerförmig ausgebildeter und mit den Stopfaggregaten verbundener Maschinenrahmen schrittweise von Schwelle zu Schwelle verfahren.EP 0 397 956 B1 describes a track construction machine composed of a total of three machine frames which are connected to one another in an articulated manner, for simultaneously stuffing and ballasting a track in use during work is continuously movable. Regardless of this continuous right of way, a further machine frame, designed as a trailer and connected to the tamping units, is moved step by step from threshold to threshold.
Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Gleisbaumaschine der gattungsgemäßen Art, die in besonders effizienter Weise sowohl zum Unterstopfen als auch Einschottern eines Gleises einsetzbar ist.The object of the present invention is to create a track construction machine of the generic type which can be used in a particularly efficient manner both for stuffing and ballasting a track.
Diese Aufgabe wird erfindungsgemäß mit einer eingangs beschriebenen Gleisbaumaschine dadurch gelöst, daß das Stopfaggregat und die Kehrbürste bezüglich der Maschinenlängsrichtung zwischen dem Gleishebe- und Richtaggregat und dem Schotterpflug angeordnet sind.This object is achieved with a track construction machine described in the introduction in that the tamping unit and the sweeping brush are arranged with respect to the machine longitudinal direction between the track lifting and straightening unit and the ballast plow.
Durch diese spezielle Anordnung der Kehrbürste ist es nun unter Beibehaltung einer konstruktiv einfachen Ausbildung der Maschinenrahmen erstmals möglich, die Maschine in der einen Arbeitsrichtung zum Unterstopfen einzusetzen, während in der anderen, entgegengesetzten Arbeitsrichtung die Einschotterung des Gleises durchgeführt wird. Diese erweiterte Einsetzbarkeit der Maschine in zwei verschiedenen Arbeitsrichtungen ermöglicht eine besonders effiziente Ausnützung der erforderlichen Gleissperre für den normalen Zugverkehr, indem das Gleis während der Hinfahrt unterstopft und im Rahmen der anschließenden Rückfahrt mit größerer Geschwindigkeit gepflügt wird. Mit der Trennung der beiden technologisch sehr unterschiedlichen Arbeitsgänge ist die Arbeitsgeschwindigkeit auch optimal an die jeweiligen Einsatzbedingungen anpaßbar. Außerdem ermöglicht dieser beidseitige Arbeitseinsatz auch die Kombination einer schrittweisen Unterstopfung insbesondere in Weichenabschnitten mit einem ein besseres Arbeitsergebnis erzielenden kontinuierlichen Pflugeinsatz.This special arrangement of the sweeping brush makes it possible for the first time, while maintaining a structurally simple design of the machine frame, to use the machine in one working direction for tamping, while in the other, opposite working direction the ballast is carried out. This extended usability of the machine in two different working directions enables a particularly efficient use of the necessary track lock for normal train traffic by stuffing the track during the outward journey and plowing at higher speed during the subsequent return journey. With the separation of the two technologically very different work steps, the working speed can also be optimally adapted to the respective operating conditions. In addition, this bilateral work assignment also enables the combination of step-by-step tamping, particularly in switch sections, with continuous plow use that achieves a better work result.
Eine Weiterbildung nach Anspruch 2 hat den Vorteil, daß von der - in bezug auf das Ende des zweiten Maschinenrahmens - zurückversetzten Fahrkabine eine verbesserte Beobachtung des Schotterpfluges für eine rasche Umleitung des Schotterflusses entsprechend den unterschiedlichen Einschotterungsverhältnissen gewährleistet ist.A further development according to claim 2 has the advantage that an improved observation of the ballast plow is ensured for a rapid diversion of the ballast flow in accordance with the different ballast conditions by the driver's cab set back with respect to the end of the second machine frame.
Eine Weiterbildung nach Anspruch 3 ermöglicht eine vorteilhafte Zwischenlagerung von überflüssigem Schotter, der bedarfsweise wiederum über die Entladeöffnungen dem Gleis zuführbar ist.A development according to
Schließlich ermöglicht die Weiterbildung der erfindungsgemäßen Maschine nach den Merkmalen 4 und 5 bei konstruktiv einfacher Ausführung des Schotterpfluges eine optimale Anpassung an unterschiedliche Einschotterungsverhältnisse.Finally, the further development of the machine according to features 4 and 5, with a structurally simple design of the ballast plow, enables optimal adaptation to different ballast conditions.
Im folgenden wird die Erfindung an Hand in der Zeichnung dargestellter Ausführungsbeispiele näher beschrieben.The invention is described in more detail below with reference to exemplary embodiments illustrated in the drawing.
