Description

The invention relates to a device for creating and / or refurbishing a railroad track consisting of a substructure and of a track according to the preamble of claim 1.

Railways consist of a substructure on which the track is located. The substructure consists of several layers, in particular of a gravel layer (also called the tarpaulin protective layer) and of a gravel layer thereon. The substructure can still have additional layers. The track consists of the transverse sleepers on which the rails are fixed. After the creation of a railway line this must be rehabilitated from time to time. This concerns in particular the substructure with its substructure layers.

Various machines are known to install the tracks and the existing example of gravel and gravel layer underlay layers according to predetermined profile cross sections. So far, these construction activities in the construction of new tracks or in the rehabilitation of existing track tracks (without existing track) always carried out with different work units. Usually, the subgrade layers such as gravel layers and gravel layers with conventional construction equipment such as excavators, rollers and other conventional machines are installed.

In addition, there are also machines that incorporate new construction tracks by machine and thereby achieve a high level of prefabricated construction. In connection with this machine However, it is necessary to install the substructure layers of the substructure in advance in order to ensure that the track construction work (with the track dismantled, does not exist). Although it is possible here to install the lowermost layer, namely the leveling protective layer of the standard structure with so-called finishers, this does not mean that a continuous installation method has yet been created that would be acceptable in terms of machine outlay and economic efficiency.

The DE 10 2010 045 068 B3 shows a rehabilitation process for the multi-layer substructure on railway lines using a head-work vehicle of the type specified. This head-work car is an immediate part of the work train as such, ie the head-work car is coupled with the work car behind this work train. This also means that the head truck can be moved on the track. On the head-work car an excavating device is arranged in the manner of an excavator.

Based on this, the object of the invention is to provide an improved device for creating and / or refurbishing a railway track consisting of a substructure and of a track.

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

As a result, a device is created by using a continuously moving work train during construction to create and / or refurbish a track consisting of a substructure and a track, by means of which the installation (and possibly also the removal) of one or more substructure layers of the track substructure in conjunction with the simultaneous track installation in a continuous process in one direction is possible. The subgrade layers relate in particular to the gravel layer (protective layer) as well as the gravel layer above it. By means of the device according to the invention, however, further substructure layers can also be installed. An inventive aspect is that the - first - work car is separate and decoupled in the head area of the work train with its paver with respect to the actual work train and - especially - does not drive on the substructure created by him. As a result, this substructure is not damaged or even destroyed. The work car with the paver can have a wheel or a crawler chassis. In principle, it is conceivable that a device which is normally used for road construction is used as a paver for track construction.

The particular advantage of the device according to the invention is that the settlement of all stages of construction takes place in a continuous installation sequence. This applies both to the subgrade layers of the substructure (ie, in particular to the protective layer of course and gravel) and to the track thereon. The use of road-bound vehicles and different installation units is thereby avoided. The device according to the invention with the work train according to the invention provides the installation of the substructure layers of the substructure and the installation of the tracks when building a new line or in a route rehabilitation in a continuous operation from a predetermined working direction.

A further advantage of the mechanical installation of substructure and track according to the invention in continuous and coherent work progress is the fulfillment of the latest guideline for the installation of the sub-base layers. According to the guidelines of this guideline, the newly installed gravel layers of the protective course layer and the gravel layers may not be used with wheel-ridden vehicles (trucks, excavators, etc.) after the rebuilding, in order to install the further gravel and gravel layers as well as the tracks for the final state. This is due to the fact that the ground layers traveling on wheel-tired vehicles would otherwise be destroyed or deformed during the application of the new layers.

The invention thus enables the objective of the new machine, the continuous installation of the required underground layers and the new track to be installed in sequence, without having to resort to wheel-tyred standard machines. The work train according to the invention makes it possible to install the materials with high-quality, leading pavers which automatically install both the width and the height of the required subgrade layers. In this case, the minimum requirement is met at the work train to install at least the gravel and the tracks from a working direction in a continuous process on new lines and rehabilitation routes in a row. The basic idea of the invention thus lies in the continuous stem of subgrade layers (irrespective of the number of subbing layers) and the simultaneous continuous laying of the track in a single operation from one working direction by upstream, separately running or coupled paver for precise installation of different substructure layers at degraded or not existing track on an old or a new built substructure for a new track construction or for a track asset rehabilitation of any kind.

The work train relies on the combination of special conveyor belt conveyors using material handling silo wagons (so-called MFS cars) as well as a special module for the laying of tracks and the final use of special leading paving rigs.

In a basic variant, this creates the possibility of bulkhead installation with simultaneous track installation in a continuous mode of operation. Here, the ballast material is fed in the direction of the work train on the so-called MFS cars. In the area of the threshold cars or Jochwagen the material is conveyed through to the installation module with appropriate conveyor belt technology. From the track laying module, the ballast is fed into the leading high-performance paver (s) via corresponding conveyor belts. These pavers incorporate the material in height and width on the gravel bed of the substructure continuously in the forward movement of the work train, depending on the installation speed of the track module. The pavers can optimally incorporate width, height, inclination or other profiles (eg center deflection or flank profiles) automatically via a laser control. The compaction can also be done optionally via the paver. An optional variable profiling of the surface of the ballast is also possible.

An optional intelligent coupling of the paver and the track installation module as well as the remaining, following machine technology can automate and combine all installation data. This relates to the control speed of the installation tiller and the track module and their successors in various variable dependencies, continue the tax rate of material supply of all machine groups and individual assemblies depending on the finishing speed or vice versa, continue the exact location and direction of the ballast bed depending on the track axis to be installed and track cant and finally the automatic alignment of the track depending on the construction of the ballast bed and gravel bed.

Conceivable further variants and options provide for the attachment of additional conveyor belts to the individual components. These correspond in terms of their operational function of the number of material layers and material flows, which are necessary for the creation or rehabilitation of the railway line.

A first variant provides according to claim 2, that the device for installation of the tracks and the device or the devices for installing the material layers for the substructure are each assigned to one or more work cars. This means that the corresponding work cars are specially designed for their respective tasks. These Work cars can be coupled together according to their needs and then form components of the work train.

A second variant in the training of the work car provides according to the embodiment in claim 3, that a kind combination work cart is provided which receives both the device for the track installation and the device for the installation of the background layer / s. Thus, even without an upstream work car with a special installation paver for the substructure with a simply constructed or with several simply constructed screeds, which are located directly on the combination work wagons for track installation, carried out an installation of one or more layers of the substrate. This simple design allows the same system variants without separately preceding work car with appropriate installation technique for the substructure materials.

According to the embodiment in claim 4, a plurality of devices (in particular in the form of corresponding plurality of work cars) are provided to install different substructure layers. These are in particular the gravel layer (layer protection layer) and the gravel layer thereon. Other or further layers are conceivable. The installation of these two (or even more) new layers and the new track is - as stated - according to the invention in a continuous process. The corresponding materials (gravel, gravel, etc.) are conveyed forward by corresponding MFS carriages via corresponding conveyor belts and fed to the corresponding equipment or the corresponding work vehicle. It is only necessary to rank corresponding MFS cars for these additional materials in the sequence of machines or work cars. The transfer of the second material flow within the overall machine series takes place via an optional intermediate transfer module on additional conveyor belts of the MFS cars.

According to the embodiment in claim 5, it is proposed that these are installed as yokes for installation of the track. In principle, however, it is also conceivable that the installation of the track is optionally carried out with long rails in the track stem. For this purpose, the rails are laid out by the machine of the work car and mounted under the machine with long rails in the course of the pre-construction work.

A further development in the Jocheinbauweise proposes according to claim 6 that stored in corresponding work cars sleepers and rails and these are assembled to yokes. Or alternatively, it is conceivable that already prefabricated yokes are stored on corresponding work car.

The development according to claim 7 proposes that the installation of the track this can be installed in the form of sleepers and long rails.

The development according to claim 8 proposes that in addition to the installation facilities for the underground layers with the corresponding work car an additional device or an additional work vehicle is connected upstream, which can be abandoned materials removed from the substructure. From there, the materials are then transported to the back to corresponding MFS wagons and deposited there. This extended method thus not only allows the continuous installation of several substructure layers of a track substructure in connection with the simultaneous track installation in a continuous process, but also makes it possible in advance to expand the subgrade layers to be replaced. Specifically, this means that the gravel to be removed is removed during a track stretch rehabilitation of a corresponding expansion module and fed to a corresponding conveyor belt. Since the conveyor belts are formed reversible, each conveyor belt can transport the materials not only in the working direction, but also vice versa. In this second case thus the old ballast by means of an excavator or other equipment, such. As milling, chain conveyor, etc. on a hopper an intermediate machine with a corresponding work car or abandoned directly to the transporting conveyor belt to the rear. From here, the old gravel and possibly other sub-layers are conveyed through the machine series to the corresponding MFS wagons. The old material can be loaded into these MFS carriages while the new material is being fed from the same or other MFS carriages in the direction of the installation unit. As a result, a simultaneous removal and installation of soil layers is possible, according to the invention with simultaneous continuous installation of the track.

The development according to claim 9 proposes that the excavated ballast is worked up in corresponding work car with appropriate workup facilities. The old gravel is thus initially expanded. Instead of the direct loading and removal of this old ballast this is processed in a ballast processing plant. This work-up may involve different steps. For example, the gravel can be washed and sieved. But other treatment methods such as breaking or sharpening can be done here in appropriate modules. After working up the ballast, the now reusable ballast is fed to the appropriate installation unit, in which the ballast is re-installed as recycling ballast. Optionally, the new gravel can be supplied to the recycling gravel. If necessary, the reusable fines of the ballast cleaning can optionally be added to a further processing module fed in the machine series and mixed with the gravel for the leveling protective layer for this base coat. In this optional treatment step, additional soil improvement measures can be carried out. By adding soil improvers and additives, a targeted formulation and grading curve in the area of the gravel and surface protection layers can be optionally produced and installed. As a result, an increase in the use of the expansion materials is ensured by these optional expansion modules. The entire machine can thus achieve a maximum utilization of all the expansion materials by expansion modules with flexible and the appropriate need equitable use. Only the pure waste materials have to be removed and disposed of. Only the modules with the corresponding work cars have to be cleaned, which correspond to the new construction and renovation requirements of the respective track construction line. The above-mentioned waste materials are supplied in all stages of execution in the opposite direction to the MFS wagon for transport to the camp. The work train can thus remove both the ballast masses, clean and reinstall. In addition, the work train can install the tracks in the same continuous process in the working direction. Only the ranking of the machine components and additional use of an insertable cleaning module for the ballast is required for this purpose.

Finally, the development proposes according to claim 10, that the work cars have conveyor belts for transporting the materials. These belts are ground conveyors, roof conveyors and transfer belts. These may for example also be formed in pairs. Also, the conveyor belts are reversible.

The Fig. 1a to 1c show a first variant of a work train for the creation or rehabilitation of a railway line. In Fig. 1a The work train is shown one above the other in different sections. The lowest representation in Fig. 1a shows the head area of the work train. An enlarged detail of this head area shows Fig. 1 b.

The railway line basically consists of a substructure 1 consisting of a layer 2 of gravel (surface protection layer) and above a layer 3 of gravel. Then there is the track 4 of sleepers 5 with rails thereon 6.

In the head area of the work train (in the drawing on the right) a first work car 7 is provided. This serves to install a layer of the substructure 1, in the present case, the layer 3 of gravel.

Behind this first work car 7 is a second work car 8. This is used to install the tracks 4 in the form of track yokes.

At this second work car 8, third work car 9 close, which fulfill a variety of tasks. Thus, these third work cars 9 are used to support the sleepers 5, rails 6 and possibly the yokes, furthermore the storage of the materials for the substructure 1, namely the gravel and the ballast. The latter work cars are designed as so-called MFS cars. In this case, intermediate cars 10 can still be provided, which serve to transfer the materials.

All work cars 7, 8, 9 and intermediate cars 10 are equipped with extending in the longitudinal direction conveyor belts 11. These conveyor belts 11, which are designed to be reversible, can be floor conveyor belts, roof conveyor belts and end transfer belts. These conveyor belts 11 can be adjusted universally in terms of their settings and transport routes, so as to ensure optimum transport of the materials. Also, the conveyor belts 11 may be formed as parallel to each other double or triple conveyor belts. Also, lateral additional conveyor belts may be provided.

• Der Arbeitszug befindet sich in einer kontinuierlichen Vorwärtsbewegung. Der erste Arbeitswagen 7 am vorderen Kopfende dient dem Einbau des Schotters auf der darunter befindlichen Schicht 2 aus Kies. Zu diesem Zweck wird der Schotter von den hinteren, dritten Arbeitswagen 9 über die Förderbänder 11 nach vorne geführt, und zwar von den entsprechenden MFS-Wagen aus, durch die entsprechenden Arbeitswagen mit den Gleisen und den Gleisbestandteilen hindurch zu dem zweiten Arbeitswagen 8 für den Gleiseinbau. Das Schottermaterial wird schließlich dem ersten Arbeitswagen 7 aufgegeben und von diesem eingebaut.

The operation is as follows:

• The work train is in a continuous forward motion. The first work car 7 at the front head end is used to install the ballast on the underlying layer 2 of gravel. For this purpose, the ballast from the rear, third work car 9 is guided over the conveyor belts 11 forward, from the corresponding MFS car, through the corresponding work car with the tracks and the track components through to the second work car 8 for track installation , The ballast material is finally given to the first work car 7 and installed by this.

After the installation of the layer 3 of ballast in the continuous flow of the work train in the behind there are working cars 8, the installation of the tracks 4. It is a special track installation wagon, which on the back of the already laid rails drives, while at the front, where there are still no rails are moved by means of a crawler chassis. This front area also has a rail drive, which is used when the crawler undercarriage is raised. The built-in by this second work car 8 tracks 4 are stored with their components, namely the sleepers 5 and the rails 6 on the underlying behind third work car 9 and are supplied to the second work car 8, if necessary.

The second embodiment in Fig. 2a to 2c differs from the first embodiment in that two first work car 7 are provided. Here, the front first installation car 7 has the task of installing the layer 2 of gravel, while the behind it located first work car 7 has the task to install the layer located above it 3 of gravel. Again, the supply of gravel and the ballast via appropriate conveyor belts 11 from the corresponding third work car 9.

The variant of the Fig. 3a to 3c is based on the basic principle on the first design variant. The difference is that before the first work car 7 at the front head end still a fourth work car 12 is provided. Like the first work car 7 of the two first embodiment variants, this fourth work car 4 is also equipped with a wheeled or crawler undercarriage. This fourth work car 12 is used to hold the developed underground layer (in this case gravel) by means of an excavator 13. Other expansion devices instead of an excavator 13 such as a scraper conveyor are conceivable. The basic principle is that the excavator 13 or other device removes the gravel of the substructure 1 and gives up the fourth work vehicle 12. From there, the ballast is transported backwards into the corresponding work car 9 by means of the conveyor belts 11. After removal, either new gravel or recycled gravel can then be reinstalled via the first work cart 7.

The fourth embodiment of the Fig. 4a and 4b sees a Kombinationsarbeitswagen 14 on the one hand for the installation of Unterbauschicht and on the other hand for installation of the track 4 before. Specifically, this technically looks so that the head of this combination work cart 14 has a kind of slider which levels the previously abandoned gravel.

The fifth variant in Fig. 5 is based on the fourth embodiment. In this fifth embodiment variant - as in the third embodiment - a fourth work car 12 is connected upstream, which serves to receive the excavated by means of an excavator 13 or the like. Schotter, which is transported away to the rear.

The sixth embodiment in Fig. 6 is based on the third embodiment, namely by the removed ballast is transported to the rear in one of the third work car 9. These have processing facilities 15 for the excavated ballast, in which the old ballast washed, sieved, classified, broken, sharpened, etc. can be. This recycled old ballast is then transported back to the first work car 7, where it is installed.

Fig. 7 Finally, shows the special second work car 8 for installation of the tracks 4. It is shown how the sleepers 5 and rails 6 mounted on corresponding third work car 9 and assembled to track yokes, which are then installed by means of a portal device of the second work car 8 on the ballast bed ,
