Description

Die Erfindung betrifft ein Verfahren zum Ausheben eines zu einem Gleis parallelen Grabens bei Bahnstrecken nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for excavating a trench parallel to a track in the case of railway lines according to the preamble of claim 1.

Oftmals ist es erforderlich, außerhalb des Gleisbereiches bei einer Bahnstrecke einen Graben auszuheben, welcher sich parallel zum Gleis erstreckt. Das Ausheben derartiger Graben wird beispielsweise dann benötigt, wenn zum Verlegen von Kabeln U-förmige Profile im Erdreich angeordnet werden müssen oder wenn ein Entwässerungskanal parallel zum Gleis der Bahnstrecke geschaffen werden soll.Often it is necessary to dig a trench outside the track area at a railway line, which extends parallel to the track. The excavation of such trench, for example, is required when laying cables for U-shaped profiles must be placed in the ground or when a drainage channel to be created parallel to the track of the railway.

Bislang werden diese Aushubarbeiten außerhalb des Gleisbereiches dadurch ausgeführt, daß sich ein baggerartiges Gerät auf einem Arbeitswagen befindet, welcher auf dem Gleis verfahrbar ist. Der Arbeitswagen fährt mit seinem Bagger an eine bestimmte Stelle, von wo aus der er die Aushubarbeiten durchführt. Sobald die Armlänge des Baggers nicht mehr ausreicht, um den Aushub des Grabens fortzuführen, fährt der Arbeitswagen ein Stück weiter, so daß der Bagger seine Arbeit fortsetzen kann.So far, these excavation work outside of the track area are carried out by a baggerartiges device is located on a work car, which is movable on the track. The work car travels with its excavator to a certain place, from where he carries out the excavation work. As soon as the arm length of the excavator is no longer sufficient to continue digging the trench, the work car moves a little further so that the excavator can continue its work.

Das Aushubmaterial, welches mittels des Baggerlöffels aufgehoben worden ist, wird auf Transportfahrzeuge verladen. Bei diesen Transportfahrzeugen kann es sich um straßentaugliche Lastkraftwagen handeln. Bei schlechter Erreichbarkeit der Baustelle können aber auch auf dem Gleis verfahrbare Standardbahnwagen verwendet werden.The excavated material, which has been lifted by means of the bucket, is loaded onto transport vehicles. These transport vehicles may be roadworthy trucks. In case of poor accessibility of the construction site but can also be used on the track movable standard railcar.

Somit wird der Aushub des Grabens nach der bekannten Arbeitsweise mit herkömmlichen Baggern ausgeführt. Hierzu wird - wie ausgeführt - mittels der Baggerschaufel der Aushub getätigt. Durch eine parallel laufende Vermessung von Hand wird die erforderliche Tiefe und Breite sowie der Abstand des Grabens zum Gleis kontrolliert und verfolgt. Oftmals erfolgt sogar der Aushubarbeitsschritt selbst in zwei getrennten Arbeitsgängen. So wird zunächst das Aushubmaterial seitlich am Graben gelagert, von wo aus in einem separaten Arbeitsgang anschließend die Verladung auf ein entsprechendes Fahrzeug erfolgt.Thus, excavation of the trench is carried out according to the known operation with conventional excavators. For this purpose - as stated - made the excavation by means of the excavator bucket. By hand, the required depth and width as well as the distance of the trench to the track are checked and tracked by a parallel measurement. Often even the excavation operation itself occurs in two separate operations. Thus, first the excavated material is stored laterally on the trench, from where in a separate operation then the loading on a corresponding vehicle.

Der Erfindung liegt daher die Aufgabe zugrunde, ein schnelleres Verfahren zum Ausheben eines zu einem Gleis parallelen Grabens bei Bahnstrecken zu schaffen.The invention is therefore an object of the invention to provide a faster method for excavating a parallel to a track trench railroad tracks.

Die technische Lösung ist gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is characterized by the features in the characterizing part of claim 1.

Die Grundidee der Erfindung liegt unter Verwendung einer entsprechenden Grabenaushebeinrichtung in einem gleisgebundenen bzw. gleisgeführten, kontinuierlichen Verfahren zum Ausheben eines zu einem Gleis parallelen Grabens einer Bahnstrecke. Der Vorteil liegt in einer kontinuierlichen Arbeitsweise mit dadurch verbundenen hohen Leistungsansätzen in einem einzigen Arbeitsgang. Der Aushub erfolgt dabei mittels einer entsprechenden Aushubeinrichtung sowohl in Erdschichten als auch optional in Gesteinsschichten, je nach Bedarf und Anforderung der örtlichen Gegebenheiten. Somit ist ein kontinuierliches Ausführen aller Arbeitsschritte in einem Durchgang und auch bei großen Entfernungen zum Gleis außerhalb des Gleisbereiches gewährleistet. Die technische Realisierung sieht somit vor, daß es sich um ein kontinuierliches Aushubverfahren des Grabens handelt. Dies bedeutet, daß der Arbeitswagen auf dem Gleis kontinuierlich fährt und daß auf diesem Arbeitswagen eine entsprechende Aushubeinrichtung angeordnet ist, welche während der Vorwärtsbewegung des Arbeitswagens synchron den Graben aushebt und das Aushubmaterial sofort dem Arbeitswagen oder einem vor- oder nachgeschalteten anderen Arbeitswagen oder einem Arbeitswagen auf einem Parallelgleis zuführt. Somit ist eine schienengebundene Aushubeinrichtung in Form einer eigenständigen, schweren Maschine auf dem Arbeitswagen geschaffen, welche einen kontinuierlichen Aushub insbesondere mittels einer Fräse in große Tiefen von mehreren Metern sowie mit großen Entfernungen zur Gleisachse von mehreren Metern gewährleistet. Das Aushubmaterial wird dabei direkt im Anschluß an den Aushub in einem kontinuierlichen Arbeitsgang für die Entsorgung verladen. Das Aushubmaterial kann dabei mittels eines Förderbands zu herkömmlichen vorgeschalteten oder nachgeschalteten oder auf einem Nachbargleis befindlichen Bahnwagen transportiert werden.The basic idea of the invention lies in the use of a corresponding trenching device in a track-guided, continuous process for excavating a trench of a railway line parallel to a track. The advantage is a continuous operation with associated high power rates in a single operation. The excavation takes place by means of a corresponding excavating both in layers of earth and optionally in rock layers, depending on the needs and requirements of local conditions. Thus, a continuous execution of all steps in a single pass and even at long distances to the track outside the track area is guaranteed. The technical realization thus provides that it is a continuous excavation of the trench. This means that the work car travels continuously on the track and that a corresponding excavating device is arranged on this work car, which synchronously digs out the trench during the forward movement of the work car and the excavated material immediately on the work car or a preceding or downstream other work car or a work car a parallel track feeds. Thus, a rail-mounted excavator in the form of a stand-alone, heavy machine on the work car created that ensures a continuous excavation in particular by means of a router in great depths of several meters and with long distances to the track axis of several meters. The excavated material is loaded directly after the excavation in a continuous operation for disposal. The excavated material can be transported by means of a conveyor belt to conventional upstream or downstream or located on a neighboring track railway cars.

Eine bevorzugte Weiterbildung schlägt gemäß Anspruch 2 vor, daß das Aushubmaterial durch die Aushubeinrichtung abgefräst wird. Es handelt sich somit um eine gleisgeführte bzw. gleisgebundene Grabenfräse. Das Abfräsen hat den Vorteil, daß dadurch ein kontinuierliches Arbeitsfluß im Sinne der kontinuierlichen Vorwärtsbewegung des Arbeitswagens gewährleistet ist.A preferred embodiment proposes according to claim 2, that the excavated material is milled by the excavating device. It is thus a track-guided or track-bound trencher. The milling has the advantage that it ensures a continuous flow of work in the sense of continuous forward movement of the work car.

Die technische Realisierung der Grabenfräse sieht gemäß der Weiterbildung in Anspruch 3 vor, daß als Fräseinrichtung ein endlos umlaufendes Band oder eine endlos umlaufende Kette oder dgl. verwendet wird, welche mit Fräselementen bestückt ist. Der Vorteil einer derartigen Fräseinrichtung besteht darin, daß ein kontinuierlicher Aushub bis in großen Tiefen von mehreren Metern sowie mit großen seitlichen Entfernungen zum Gleis von mehreren Metern möglich ist. Dabei ist die Fräseinrichtung vorzugsweise auswechselbar. Durch unterschiedlich breite Fräseinrichtungen können somit auf einfache Weise unterschiedlich breite Gräben ausgehoben werden.The technical realization of the trencher provides according to the embodiment in claim 3, that as a milling device, an endlessly circulating belt or an endlessly circulating chain or the like. Is used, which is equipped with cutting elements. The advantage of such a milling device is that a continuous excavation is possible up to great depths of several meters and with large lateral distances to the track of several meters. In this case, the milling device is preferably replaceable. By different width milling devices can thus be excavated in a simple way different width trenches.

Dabei entspricht gemäß der Weiterbildung in Anspruch 4 die Breite der Fräseinrichtung vorzugsweise der Breite des auszuhebenden Grabens. Dies bedeutet, daß in einem einzigen Arbeitsgang mit einem einzigen Vorwärtstrieb der Fräseinrichtung der Graben entsprechend den geforderten Dimensionierungen ausgehoben werden kann.In this case, according to the embodiment in claim 4, the width of the milling device preferably corresponds to the width of the digging trench. This means that in a single operation with a single forward drive of the milling device of the trench can be excavated according to the required dimensions.

Eine bevorzugte Weiterbildung schlägt gemäß Anspruch 5 vor, daß die Aushubeinrichtung an einem quer zur Bewegungsrichtung des Arbeitswagens teleskopierbaren Ausleger angeordnet ist. Dieser auskragendes Ausleger, an dessen Ende sich die Aushubeinrichtung, insbesondere die Fräseinrichtung befindet, hat den Vorteil, daß große Entfernungen zwischen dem Gleis und dem auszuhebenden Graben überbrückt werden können, und zwar Entfernungen von mehreren Metern. Die Fräseinrichtung kann dabei schwenkbar sein, um dadurch Hindernisse beispielsweise in Form von Masten umfahren zu können. Die stabile Führung der Aushubeinrichtung wird durch die Kompaktbauweise des Arbeitswagens mit dem entsprechenden Aufbau für die Aushubeinrichtung erreicht. Das Gewicht der vorbeschriebenen Einheit dient dabei dazu, dem Kippmoment der auskragenden Aushubeinrichtung entgegenzuwirken. Das Gewicht kann hierbei auch optional variabel gewählt werden, indem beispielsweise der Arbeitswagen mit Zusatzgewichten ausgerüstet wird. Somit ist ein kontinuierliches Ausführen sämtlicher Arbeitsschritte in einem Durchgang auch bei großer zeitlicher Entfernung zum Gleis gewährleistet.A preferred development proposes according to claim 5, that the excavating device is arranged on a transversely to the direction of movement of the work carriage telescopic boom. This projecting boom, at the end of the excavating device, in particular the milling device is, has the advantage that large distances between the track and the trench to be excavated can be bridged, and indeed distances of several meters. The milling device can be pivotable in order to avoid obstacles in the form of masts, for example. The stable guidance of the excavating device is achieved by the compact design of the work cart with the corresponding structure for the excavating device. The weight of the unit described above serves to counteract the overturning moment of the projecting excavating device. The weight can also optionally be chosen variable, for example, by the work car is equipped with additional weights. Thus, a continuous execution of all operations in one pass is guaranteed even at a long time distance to the track.

Die Weiterbildung gemäß Anspruch 6 hat den Vorteil, daß auf technisch einfache Weise sehr große Tiefen von mehreren Metern ausgehoben werden können. Außerdem ist eine Möglichkeit zum Umfahren von Hindernissen geschaffen. Somit können die Teleskoparme die Fräseinrichtung in ihrer geforderten Lage hinsichtlich Höhe und Richtung sowie hinsichtlich der Neigung durch eine entsprechende Verschwenkbewegung halten.The development according to claim 6 has the advantage that in a technically simple way very large depths of several meters can be excavated. In addition, a possibility for avoiding obstacles is created. Thus, the telescopic arms hold the milling device in its required position in terms of height and direction and in terms of inclination by a corresponding pivoting movement.

Die Auswechselbarkeit der Aushubeinrichtung am Arbeitswagen gemäß der Weiterbildung in Anspruch 7 hat den Vorteil, daß entsprechend den variablen Baustellenanforderungsprofilen entsprechende Aushubeinrichtungen eingesetzt werden können. Die Auswechselbarkeit hat aber auch den Vorteil, daß andere Werkzeuge als Aushubeinrichtungen als optionale Zusatzlösung angebaut werden können, beispielsweise Bohrgeräte oder Verdichtgeräge oder sonstige Werkzeuge jeglicher Art.The interchangeability of the excavating device on the work cart according to the embodiment in claim 7 has the advantage that according to the variable construction site requirement profiles corresponding excavation equipment can be used. The interchangeability but also has the advantage that tools other than excavating equipment can be grown as an optional additional solution, such as drills or Verdichtgeräge or other tools of any kind.

Die Weiterbildung gemäß Anspruch 8 hat den Vorteil, daß die Positionierung der Aushubeinrichtung, insbesondere der Fräseinrichtung automatisch hinsichtlich Höhe und Seitenlage sowie hinsichtlich der Neigung automatisch reguliert wird, ohne daß die Grabenmaße von Hand vermessen werden müssen. So kann die automatische Neigungsregulierung der Fräseinrichtung beispielsweise über Lasersteuerung in Abhängigkeit von der Tiefe sowie Breite des auszuhebenden Grabens erfolgen. Somit kann die komplette Vorrichtung die Arbeitsabläufe teilautomatisch oder vollautomatisch insbesondere mittels einer Lasersteuerung steuern.The development according to claim 8 has the advantage that the positioning of the excavating device, in particular the milling device is automatically automatically adjusted in terms of height and lateral position and in terms of inclination, without the trench dimensions must be measured by hand. Thus, the automatic inclination regulation of the milling device can take place, for example, via laser control as a function of the depth and width of the trench to be excavated. Thus, the entire device can control the work processes semi-automatic or fully automatic, in particular by means of a laser control.

Das Zuführen des Aushubmaterials zum Arbeitswagen kann gemäß der Weiterbildung in Anspruch 9 mittels eines Förderbandes erfolgen. Somit ist die gleisgebundene bzw. gleisgeführte Aushubeinrichtung insbesondere in Form einer Grabenfräse mit einer Förderbandtechnik dahingehend kombiniert, daß eine direkte Abförderung des Aushubmaterials auf ein angeschlossenes Förderband im kontinuierlichen Arbeitsgang erfolgt.The feeding of the excavated material to the work car can be carried out according to the embodiment in claim 9 by means of a conveyor belt. Thus, the track-bound or track-guided excavating device is combined in particular in the form of a trench cutter with a conveyor belt technology to the effect that a direct discharge of the excavated material on a connected conveyor belt in a continuous operation.

Vorzugsweise ist dabei gemäß der Weiterbildung in Anspruch 10 das Förderband um eine vertikale Achse verschwenkbar. Auf diese Weise kann das Aushubmaterial sowohl auf Bahnwagen vor Kopf oder aber auch auf ein Nachbargleisfahrzeug oder einen Straßenlastkraftwagen verladen werden.Preferably, according to the embodiment in claim 10, the conveyor belt is pivotable about a vertical axis. In this way, the excavated material can be loaded both on railway wagon head or even on a neighboring track vehicle or a road truck.

An embodiment of a device for excavating a trench parallel to a track in railway lines is described below with reference to the drawings. In these shows:
Fig. 1
a side view of the device;
Fig. 2
a section along the line AA in Fig. 1 ,

Auf einem Gleis 1 einer Bahnstrecke ist ein Arbeitswagen 2 mit einem Oberbau 3 verfahrbar. Aufgabe dieses Arbeitswagens 2 mit einem entsprechenden Werkzeug ist es, mit Abstand seitlich neben dem Gleis 1 einen Graben 4 auszuheben.On a track 1 a railway track a work car 2 with a superstructure 3 is movable. The task of this work cart 2 with a corresponding tool is to excavate a trench 4 at a distance laterally next to the track 1.

Zu diesem Zweck ist ein am Oberbau 3 des Arbeitswagens 2 seitlich auskragender, teleskopierbarer Ausleger 5 vorgesehen. Am äußeren Ende dieses Auslegers 5 befindet sich eine Aushubeinrichtung 6. Diese Aushubeinrichtung 6 ist als Fräseinrichtung 7 in Form eines endlos umlaufendes Bandes 8 mit darauf befindlichen Fräselementen 9 ausgebildet.For this purpose, a laterally projecting on the superstructure 3 of the work cart 2, telescopic boom 5 is provided. At the outer end of this boom 5 there is an excavating device 6. This excavating device 6 is designed as a milling device 7 in the form of an endlessly circulating belt 8 with cutting elements 9 located thereon.

Weiterhin ist ein Förderband 10 vorgesehen. Dieses mündet mit seinem vorderen Ende oberhalb eines - nicht dargestellten - weiteren Arbeitswagens 2 auf dem gleichen Gleis 1 oder auf einem Nachbargleis. Dieses Förderband 10 ist um eine vertikale Achse verschwenkbar.Furthermore, a conveyor belt 10 is provided. This opens with its front end above a - not shown - another work car 2 on the same track 1 or on a neighboring track. This conveyor belt 10 is pivotable about a vertical axis.

Die Funktionsweise der Grabenaushubvorrichtung ist wie folgt:

  • Zunächst bringt der teleskopierbare Ausleger 5 die Fräseinrichtung 7 der Aushubeinrichtung 6 in den richtigen seitlichen Abstand bezüglich des Gleises 1. Es ist aber genau die Stelle, wo der Graben 4 ausgehoben werden soll.
The operation of the trenching apparatus is as follows:
  • First, the telescopic boom 5 brings the milling device 7 of the excavating device 6 in the correct lateral distance with respect to the track 1. However, it is exactly the point where the trench 4 is to be excavated.

Anschließend wird die Fräseinrichtung 7 mittels eines entsprechenden Antriebs nach unten verschwenkt, und zwar mit einem Neigungswinkel, wie er in Fig. 1 erkennbar ist. Durch das endlos umlaufende Band 8 wird mittels der Fräselemente 9 das Erdreich abgefräst, so daß der Graben 4 entsteht. Wesentlich dabei ist, daß sich während dieses Fräsvorganges der Arbeitswagen 2 kontinuierlich vorwärts bewegt. Dies bedeutet, daß während dieses Vorwärtstriebs des Arbeitswagens 2 das Erdreich kontinuierlich mittels der Fräseinrichtung 7 abgefräst wird und somit entsprechend dem Vorwärtstrieb des Arbeitswagens 2 der Graben 4 geschaffen wird. Durch eine Höhenverstellung des Auslegers 5 an seinem Oberbau 3 des Arbeitswagens 2 und/oder durch die Neigung der Fräseinrichtung 7 kann die Tiefe des Grabens 4 vorherbestimmt werden. Die Steuerung erfolgt dabei vorzugsweise automatisch mittels einer Laserpositioniereinrichtung.Subsequently, the milling device 7 is pivoted by means of a corresponding drive downwards, with an inclination angle, as in Fig. 1 is recognizable. Through the endless circulating belt 8, the soil is milled off by means of the cutting elements 9, so that the trench 4 is formed. It is essential that during this milling process of the work car 2 moves continuously forward. This means that during this forward drive of the work cart 2, the soil is continuously milled by means of the milling device 7 and thus according to the forward drive of the work cart 2 of the trench 4 is created. By a height adjustment of the boom 5 at its superstructure 3 of the work cart 2 and / or by the inclination of the milling device 7, the depth of the trench 4 can be predetermined. The control is preferably carried out automatically by means of a laser positioning.

Das von der Fräseinrichtung 7 abgefräste Aushubmaterial 11 wird dem Förderband 10 aufgegeben. Dieses Förderband 10 wird um seine vertikale Achse derart verschwenkt, daß das vordere Ende dieses Förderbands 10 das Aushubmaterial 11 in einen entsprechenden Vorratsbehälter abwirft. Es kann sich dabei um den Arbeitswagen 2, um einen dahinter oder davor befindlichen Arbeitswagen 2, um einen Arbeitswagen 2 auf einem Nachbargleis oder um einen Lastkraftwagen handeln.The excavated from the milling device 7 excavated material 11 is the conveyor belt 10 abandoned. This conveyor belt 10 is pivoted about its vertical axis such that the front end of this conveyor belt 10 throws the excavated material 11 in a corresponding reservoir. This can be the work car 2, a work car 2 located behind or in front of it, a work car 2 on a neighboring track or a lorry.
