EP1757732A1 - Method for reconditionig the ballast bed of a railway track - Google Patents

Abstract

The method involves coupling two or more base units (7) depending on desired operating speed and distance to be worked. Olden and new ballast containers (1, 2) adapted to respective function are designed as foldable containers. The base units have the ballast foldable containers for receiving an old ballast (8) and for delivering a new ballast, and are connected with receiving devices and new ballast disposing devices. An independent claim is also included for a device for reconstructing a ballast substructure of a railway track.

Description

The invention relates to a method for rehabilitating the ballast bedding of track systems rail-bound transport, which can be adapted to the local conditions processing line and duration per unit distance.

The repair of track bedding must be repeated at regular intervals, as the track substructure loses stability over the course of time. This results in a shortening of the service life of the track system.

The forces which are caused on railroad tracks by trains traveling overhead and other rail vehicles, lead to a displacement of rails and sleepers within the stones or ballast. In particular, the vertical position of the sleepers within the bedding ballast leads to a change in the track height. This requires a periodic reorientation of the track in the bedding. In order to shut down the operation of the track system during the repair work only for the shortest possible period of time, so-called track construction trains have been developed, which include different processing stations and carry out the repair in a continuous operation as possible. For this purpose, different solutions are known.

For example, a track-movable machine has become known, on the machine frame a clearing device is mounted vertically adjustable. This has an inserted in the work below the track, endless clearing chain, by means of which gravel is taken from the track bedding and transported to a screening plant. In it, the overburden is separated from the ballast and transported for disposal to the forward end of the machine. The cleaned ballast can be thrown back onto the track - held up by a lifting device - via a conveyor. Instead, new ballast can be brought from the rear end of this machine and released onto the exposed surface.

Also known is a ballast bed cleaning machine, which has 2 each attached to a longitudinal side of a machine frame, designed as a raking bar with a continuous endless clearing chain trained clearing devices.

These baffles are rotatable about a provided at its longitudinal end, vertical pivot axis and height adjustable and are lowered for ballast clearing in the Gleisbettungsflanken and then pivoted from both sides under the track grid. Now, the ballast located below the track grate is transported to the track flanks and fed via an obliquely leading top conveyor assembly a screen for cleaning.

References to the solution according to the invention are not apparent here.

Also known is a method for the rehabilitation of ballast foundations on tracks, wherein the clearing vehicle has a machine frame which can be moved at the end by rail drives and additionally has a track lifting device. Directly behind the endless chain around the track led around the clearing chain is a ballastless Umbaulücke. The broaching chain can be set in rotation by drives or height and side adjustable. At the rear end of the clearing vehicle, a filling station is provided for filling containers. This is composed of a running in the machine direction, arranged between crane rails, a drive having bottom conveyor belt and a conveyor together. For transporting the container, a gantry crane with a travel drive is provided, which can be moved on flange tracks on the crane rails. For container emptying, the gantry crane has a tilting device which is rotatable about a normal to the machine longitudinal direction and horizontal axis.

An anticipation of the concept of the invention is also here - even partially - not recognizable.

The invention has for its object to provide a compact and lightweight system for exchanging track ballast in one operation, which is particularly suitable for use in the subway or tunnel area by its small dimensions and beyond for quick transport to the place of use on trucks can be loaded and an adjustment of the working speed - depending on the route specification - allows.

According to the invention, this object is achieved by a method for rehabilitating the gravel bedding of track systems, wherein the ballast exchange system consists of a Schotterfaltcontainer for Altschotterauhahme and a second type for Neuschotterauhahme connected to a respective receiving unit and a Neuschotter distribution unit, depending on the desired operating speed and to be processed route 2 or more base units can be additively coupled, the old and Neuschottercontainer - adapted to the respective function - are designed as a folding container and takes the recording of old and the application of Neuschotters in one operation.

In the advantageous solution according to the invention the Schotterfaltcontainer be placed on each a transport car, the suction, which are provided on Altschottercontainer, from one - depending on the site - upstream or downstream compressor car with compressed air to generate the suction vacuum are supplied.

In a solution according to the invention, the compressor wagon is placed before or behind the train in the ballast exchange system.

A further variant according to the invention claims ballast folding containers which can be removed or dismantled, wherein these ballast folding containers can be folded together when empty and, as an essential advantage according to the invention, per transport truck e.g. 4 folded ballast container can be transported.

The receiving device ends in a nozzle which is arranged to be movable so that it can also be pushed under the sleepers, to suck from there the old ballast.

An essential advantage of the invention according to the ballast exchange system for rapid transport from site A to B is the significant storage space reduction of Schotterfaltcontainer, which ensures that can be used in the transport state on the truck per Schotterfaltcontainer as Transporthöhe measure the sum of constructively superimposed wall thicknesses.

In the process according to the invention one travels with the semi-loaded work train - wherein the Schotterfaltcontainer is loaded for Neuschotter - in the track to be processed and can also extend after completion of the work again with the half-loaded train, now filled the Schotterfaltcontainer type 1 with old ballast and the Neuschottercontainer are empty.

A variant according to the invention is shown in the drawings.
