Abstract

A head work wagon (1) provided at the tip or in the end the work train is provided with an excavation device (2) that excavates bottom material or ballast provided at tracks. The bottom material and ballast are conveyed from loading station of the head work wagon to rear work wagons (12,13,17,18) through conveyer (14). The new bottom material and new ballast are conveyed from rear work wagons to head work wagon through conveyer so as to construct new track. An independent claim is included for head work wagon.

Description

The invention relates to a method for rehabilitating existing of gravel and from underlying soil materials multilayer substructure consisting of sleepers and rails tracks on rail lines according to the preamble of patent claim 1.

Railways consist of a multi-layered substructure on which the tracks are located. These tracks consist of the sleepers and the rails. The multi-layer substructure initially consists of soil layers. These are, in particular, a protective cover layer, an antifreeze layer and possibly further layers. On these soil layers is then a gravel layer. This serves to receive the track.

The above-described substructure must be rehabilitated from time to time. The track itself is not necessarily always renewed. It can also be renewed or partially renewed at the same time. There are various procedures for renovation and renewal of underground layers and track systems.

The invention has for its object to provide an improved method for rehabilitating existing of ballast and from underlying soil layers multi-layer substructure consisting of sleepers and rails tracks on rail lines.

The technical solution is characterized by the features in the characterizing part of claim 1.

As a result, an improved method for refurbishing existing of gravel and underlying soil layers consisting of multi-layer substructure consisting of sleepers and rails tracks on railways created, which is characterized by a simple technical realization using flexible working car with appropriate machinery. Thus, a conversion technology for the track renewal with subsurface remediation and ballast cleaning or ballast renewal with logistical advantages is created. The heart of this is the inventive head-trolley either at the top or at the end of the work train. As a logistical unit, this head-driven utility vehicle is responsible for the handling of the track as well as for the removal and installation of the ballast and ground materials. Thus, the head-work car is initially intended that the removed track is transported along this head-work vehicle to the rear and stored there either in the head-work car or preferably in one of the work cars located behind it. The track is pushed in particular by the way by the head work car. The passage of the track can be done in different ways. During the pushing through the expansion process and, if necessary, the installation process is interrupted. However, even in the event that the installation process would have to be interrupted for a short time, the interruption does not result in any discontinuity of the workflow since there is no shift interruption. In particular, no new approach of the layers is required because the installation units for the ballast and for the soil materials remain only at a certain point.

The head-working car according to the invention allows a track renewal and simultaneous underground remediation, with all to be built and installed soil layers can be handled from a storage place. At the same time, the old tracks are removed and reinstalled. But they can also be replaced by new tracks. The tracks can be fed from the opposite direction to the ground materials the head-car, since they are logistically independent of the soil layers. In order to keep the machine design simple, the removal and installation work of the substructure layers are carried out with the track dismantled. The special feature lies in the type of expansion of the subgrade layers and in the installation of the old or a new track.

This creates an overall process in a continuous conversion process in the area of soil layers. Here are all layers in a lineup behind the Head work car arranged. This is made possible by the use of material trolleys with reversible transfer technology. This has the advantage that all materials of the subgrade layers (old soil material / new soil material / old gravel / refurbished gravel / new gravel) can be supplied and removed from one working direction. Thus, only one logistical workstation is required for all soil and ballast materials.

Overall, all materials can be replaced or reused by a specific processing of individual materials. The materials to be removed can be transported to their destinations, namely the corresponding work car accordingly. Thus, the gravel to be removed and worked up can be abandoned by means of a lifting unit of a loading station. The ballast can then be transported on a conveyor belt to a ballast cleaning unit of a corresponding work car. In this ballast cleaning unit, the ballast is recycled according to the work-up procedure to be selected and, if necessary, additionally washed. The washing can be done optionally. The non-reusable dirt and fines of the ballast can then be transported by the cleaning unit to appropriate bunker cars. The reusable and recycled or washed ballast masses are then transported via conveyor belts back to the installation unit of the head-working car. Here they are applied to the base coat and leveled and compacted if necessary.

Accordingly, the old soil layers (usually antifreeze layer and layer protection layer) are abandoned by means of a lifting unit on an associated feeding station. From there, the old soil layers are transported via conveyor belts along the work cars of the various stations of the total tractor unit. The transport ends for the excavated soil layers in their bunker cars. At the same time, the new soil material is transported from their bunker wagons over the trolleys to the appropriate installation of the head-work wagon. In order to transfer the substances from the bunker trolley to the conveyor belts, it is useful and helpful to interpose a transfer trolley. With the appropriate installation unit of the Kopf-Arbeitswagens the new soil material (usually frost protection layer and layer protection layer) is installed, leveled and compacted if necessary. However, other processes can also be selected than the procedure described above. The goal is a complete renewal of the underground layers. For this purpose, only the conveyor belts and the work car in the feeder must be changed accordingly.

The excavation unit described above solves both the gravel layer and the old soil layer. The ballast layer is hereby transferred to the loading station by means of the excavating unit. The old soil layer is also transferred via a corresponding feed station by means of the excavation unit. The excavation unit can be based on different techniques. The simplest technique is an excavator unit. However, other possible techniques may also be used, for example conveyor chains, milling machines, paddle wheels or other conceivable solutions by means of which the excavated material can be released and loaded.

At the same time, the track can be removed and reinstalled using the technology described above. It can be expanded both the old track and then reinstalled. Alternatively, it is also possible that the old track can be replaced with a new track. Partial renewal is also possible. If a simultaneous track material replacement in the sense of a track renewal should take place, these new tracks are preferably fed from the opposite direction of the machine. Here it is possible to renew individual or all track construction materials. The old track construction materials are loaded onto the work cars while the new track construction materials are unloaded and installed. If necessary, the work car can also be converted from old to new track materials. The longitudinal process on the work car takes place by means of existing on the market techniques such as gantry cranes or the like. For loading and unloading the track construction materials can also be a standard technique, namely the so-called rail crane can be used.

Preferably, according to the embodiment in claim 2, the track is transported through the head-work car to the rear. This means that the track is in a sense immersed in the gullet of the head-work vehicle and is transported from there to the rear. This can also be done underfloor.

According to the embodiment in claim 3, the track can be expanded and installed yoke wise.

According to the embodiment in claim 4, the track can either be removed and installed by the inventive head-work car. But it is also possible that the removal or installation of the track can be done from a neighboring track. In the event that a new track is installed, this can also be done by a movable on the track, separate work unit.

In order to be able to easily carry out the transport of the track through the head-work car, according to the development in claim 5, the feed stations for the ballast and for the soil materials are preferably raised. This increase allows the conveyance of the tracks through the excavation unit according to the invention below the raised assemblies.

The transport of the ballast and the soil materials is carried out according to the embodiment in claim 6 by means of conveyor belts. The track construction materials, namely the track yokes or the rails and sleepers can be fed from the opposite direction to these base materials of the head-working machine because they are logistically independent of the soil layers. The conveyor belt systems described above can be arranged arbitrarily in order to transport the corresponding materials to their processing station or bunker.

According to the embodiment in claim 7, the conveyor belts are adjustable so that a reversible transport direction can be realized.

The development according to claim 8 suggests various types of work cars.

Finally, the development proposes according to claim 9, that the work train has at least one transfer car. This transfer car is particularly useful for transferring the soil from the bunker cars on the transfer belts.

The work train, as in Fig. 1 is shown, consists of a variety of work cars. For better representation, the in Fig. 1 shown Arbeitszug divided into four sections and shown one above the other. The second representation is to be added on the left to the top representation, the third representation on the left to be added to the second representation, etc.

The heart of the work train is the head work car 1 either at the top or at the end of the work train. This head work cart 1 has an excavating device 2 in the form of an excavator. Furthermore, two feed stations 3, 4 and two mounting devices 5, 6 are provided.

• Zunächst werden die aus Schwellen 7 und Schienen 8 bestehenden Gleise 9 ausgebaut. Dies kann durch den Kopf-Arbeitswagen 1 erfolgen aber auch durch eine separate Arbeitswageneinheit auf dem gleichen Gleis 9 oder auf einem Nachbargleis. Auf jeden Fall wird das jochweise ausgebaute Gleis 9 vorzugsweise mittels der Aushubeinrichtung 2 durch den Kopf-Arbeitswagen 1 hindurch nach hinten transportiert, wie dies in den Fig. 3a bis 3c erkennbar ist. Die Aufgabestationen 3, 4 sowie Einbaueinrichtungen 5, 6 sind dabei nach oben gefahren.

The working of the work train is as follows:

• First, consisting of sleepers 7 and 8 rails 9 are removed. This can be done by the head work car 1 but also by a separate work car unit on the same track 9 or on a neighboring track. In any case, the yokewise developed track 9 is preferably transported by means of the excavating device 2 through the head-work car 1 through to the rear, as shown in the Fig. 3a to 3c is recognizable. The feeding stations 3, 4 and installation devices 5, 6 have gone up here.

After the expansion of the track 9 and its transport to the rear, first the excavating device 2 ensures the excavation of the ballast 10. The excavating device 2 releases the excavated ballast 10 of the loading station 3. Starting from this feeding station 3, the ballast 10 is fed by means of a conveyor belt 11 to a work cart 12 for ballast processing. In this, the ballast can be recycled 10 and possibly additionally washed, the washing can optionally be done. The non-reusable dirt and fines of the ballast 10 are transported from the work car 12 to the work car 13 and bunkered there. The reusable and recycled as well as possibly the washed ballast are transported via conveyor belts 14 back to the head-work car 1 and the installation device 5 abandoned for the recycled ballast 10.

After removal of the ballast 10, the underlying soil material 15 (surface protection layer and possibly frost protection layer) is excavated by means of the excavating device 2 and the feeding station 4 of the head-working vehicle 1 abandoned. From there, the transport of the old soil material 15 by means of conveyor belts 16 over all work cars away up to the work car 17, where the old soil materials 15 are bunkered. The transport for the excavated soil materials 15 ends there in this bunker car. At the same time, new floor materials 15 are transported by their work car 18 via corresponding conveyor belts 19 to the installation device 6 of the head work cart 1. To transfer the new soil materials from their bunker cars on the conveyor belts 19, it makes sense and helpful to interpose a transfer car 20. With the installation device 6, the new soil material 15 is installed, leveled and, if necessary, compacted. Subsequently, the ballast 10 is installed by means of the installation device 5 of the head-working vehicle 1. In addition, a fleece can be installed in the multi-layered substructure.

Finally, the track 9 is reinstalled. It can be used while the old, yoke-way track 9. For this purpose, the track 9 is transported through the head-work car 1 through to the front to the installation site.

According to the variant in the Fig. 4a and 4b a separate railcar 21 is provided. This builds a new track 9. For this purpose, the head-work car 1 is at the end of the work train.
