Description

The invention relates to a work vehicle for track construction in railway lines, a work train for rehabilitation of the existing of a substructure and a track railway line, a use of the work vehicle and a method for operating a work train for rehabilitation of a railway line.

The work cart according to the invention for track construction on railway lines is intended and suitable to be ranked in a series of so-called material handling silo wagons (MFS cars). The work trolley according to the invention and the MFS trolleys are part of a work train for the rehabilitation (but also for the preparation) of the existing of a substructure and a track railway line. The MFS trolleys have at least one continuous bottom conveyor belt and at one end or at both ends a transfer conveyor for transferring material from one MFS car to the next MFS car. Optionally, one or more roof conveyor belts may be provided. These also have at least one transfer conveyor belt at the end. By contrast, the work trolley according to the invention can be a "conventional" work trolley on which, for example, materials such as sleepers can be stored. This work cart does not necessarily have conveyor belts for material transport, but may have such conveyor belts. The work trolley according to the invention may also be an independent cleaning trolley or a material trolley.

The classic MFS wagons have the task of transporting the materials on the construction sites on the one hand and buffering the materials on the other. In this case, the materials can be transported on the track axis in one direction or in opposite directions, without having to leave the track restraint profile (clearance) with the material by means of these MFS cars.

Furthermore, so-called track-laying machines are known, which receive the excavated ballast, work up and reinstall. These machines are also called ballast cleaning machines. In the conventional cleaning machines, the material is cleaned within the entire machine. The overall machine can consist of several related individual components. The cleaned track ballast material is returned to the existing track body, while the waste material (undersize and dirt) is passed to the classic MFS wagon for removal. There are also cleaning techniques, which are arranged within a trailer on track-bound machines within a train and form there specifically for this lined-up machine technology, the cleaning unit.

These ballast cleaning machines are very complex structures, which are correspondingly complex and solid. They are integrated in a corresponding work car and have - above all - at the same time also a device for removing the ballast and a device for re-installation of the reconditioned ballast. However, this means that these ballast cleaning machines are very special and individual and can only be used for this one purpose.

EP 1 249 537 A2 discloses a method for cleaning bulk material using a track treatment train. This has a plurality of successively ranked work car, including work car with reprocessing facilities for developed gravel, which is expanded by a respect to the working direction behind this queued other work car, which has an expansion unit for gravel and an expansion unit for other substructure materials. From this expansion trolley upper roof conveyors promote the substructure materials on the other work cars in the direction of a waste cart at the head of the work train, and lower roof conveyors promote the developed gravel to the work car with the ballast processing facility where the developed ballast of the ballast processing equipment fed in the opposite direction or in Working direction is given to a bypass conveyor to dissipate the ballast with the substructure materials to the overburden at the head of the work train. In addition to the two roof conveyor belts, which are bent at one end to overlap with the conveyor belt of an adjacent, behind it arranged car, the work car with the ballast processing device, a bottom floor conveyor for removing the sieve residues from the ballast processing in the working direction, the one end to overlap with the conveyor belt in front arranged cart is bent, which transports the sieve residues together with the substructure materials and possibly gravel to Abraumwagen at the head of the work train. The arrangement of the conveyor belts within a carriage and between the carriages and the transport direction of each conveyor belt are fixed and can not be changed. The work train only works in a defined sequence.

The invention has for its object to provide a work car for track construction in railway lines of the type specified, on the one hand a special area of responsibility is supplied and on the other hand still universally applicable and can be queued at any point within a work train.

The object is achieved by a work cart with the features of claim 1.

Another object of the invention is to provide a suitably universally applicable and modular assemblable work train for rehabilitation of the existing of a substructure and a track railway line.

This object is achieved by a work train with the features of claim 9.

A use of a universally applicable work car in a work train for the rehabilitation of the railway line is disclosed with the features of claim 18.

A method with the features of claim 22 solves the problem of providing a flexible logistical transport and delivery within a train modularly flexible train.

A first embodiment of a trolley according to the invention for track construction in railway lines provides that this work trolley can be modularly ranked at any location in any order of other work cars within a work train for rehabilitation of existing from a substructure and track track. In this case, the work car has a reprocessing device for removed ballast and / or other substructure materials either for a subsequent complete or partial replacement or removal. However, the ballast and / or the other substructure materials are neither removed nor installed by this work car. By contrast, the working carriage has conveyor belts for feeding the removed ballast and / or other substructure materials to the reprocessing device, for removing processed materials and for transporting through materials of the adjacent further work carts. As conveyor belts for supplying the excavated ballast and / or other substructure materials to the reprocessing device and the removal of processed materials are at least one upper floor conveyor belt, a lower floor conveyor belt, end transfer belts, which can be moved up and down and on a carriage retractable and extendable, and a roof conveyor belt is provided, which extends to a feed point of the reprocessing device and the end is pivoted in each case pivotally. Here are the upper floor conveyor belt, the lower floor conveyor belt, the end transfer belts and the roof conveyor belt carried reversible with respect to their transport direction and the upper floor conveyor is also displaceable in its end position and / or bent. Furthermore, the work car has a transfer conveyor belt in the roof area, which is designed to be reversible with respect to its transport direction and extends to the roof conveyor from the other side of the feed point and the end is pivoted upward and downward bendable. Thereby, the conveyor belts of the work vehicle can be used for transporting or transporting materials to or from a specific location of a machine area adjacent other work cars of the work train in both directions, the roof conveyor or the transfer conveyor in the roof area individually as a conveyor belt for supplying materials to the Processing device and the roof conveyor and the transfer conveyor in the roof area are used together as a conveyor belt for transporting materials. The materials need not have anything to do with the processing of excavated ballast and / or other substructure materials in the work-cart with work-up equipment, since during transport or transit of these materials the operation of the work-up equipment for all or part of the applications for which the work car is designed and usable, can be interrupted.

Unlike in the prior art, all conveyor belts according to the invention are reversible with respect to their transport direction and the transfer conveyor belts pivotable downwards and upwards and retractable and extendable on a carriage. Furthermore, the roof conveyor belt is bent at each end pivotally and the upper floor conveyor belt displaceable in its end position and / or bent. This makes it possible that with the conveyor belts, the variable promotion in both directions in and / or through the work car through in various ways is possible, so that it can be queued at any point within a work train.

Thus, the continuous roof conveyor belt is designed to be movable or bendable, so that it can also be used as a conveyor belt for feeding materials to a work-up module and / or as a conveyor belt for the transport of materials. As a result, a universal material transport is possible and realized.

This creates a special modular work cart in the form of a cleaning or refurbishment module for cleaning or refurbishment of gravel and / or earth masses within a modular design work group of individual machines. The work cart according to the invention is in a series of material handling silo wagons (MFS wagons) or the like queued. The cleaning module according to the invention is variable and fully functional and can be queued and used anywhere within a train of material handling silo wagons or the like. The processing of the ballast and / or the earth masses (ie those components of the track bed, which are located below the ballast) is to be understood in the most general sense.

It is essential in the case of the modular work cart according to the invention that this work cart represents a completely independent, modular unit or machine which can be used and used completely independently of other work cars or machines. This also means that the modular work car according to the invention does not rely on it and is not intended to be classified in a very specific composite of several work cars, which define a machine in their entirety. The modular work cart according to the invention is thus to be understood as an independent machine and not part of an overall machine, which is distributed on the basis of the machine length on several work cars. It is also essential that the gravel and / or the other substructure materials are not removed by the work trolley according to the invention and possibly re-installed. In addition to the complete or partial replacement of the materials within the framework of the removal and replacement cycle, removal of the materials is also possible without these being reinstalled within this cycle. They can be deposited or processed elsewhere after temporary storage on appropriate work cars.

The particular advantage of the work cart according to the invention is that it is based on a conventional, classic work car, which is equipped or retrofitted with a special processing device for the removed ballast and / or other substructure materials. In this case, this work car is designed with its reprocessing device only for this specific purpose. In particular, the work cart according to the invention is not suitable and is not intended to remove and install the ballast and / or the other substructure materials. The removal and replacement is carried out by other, special work cars, which are not work cars in the meaning of the invention. As a result, a highly modular system for the provision of a work train in track construction is created, with each work car of this work train defining a special work module.

Thus, according to the invention by means of the modified work carriage of the invention, a processing of the developed ballast and / or other substructure materials without complex cleaning machines possible, and especially regardless of the type of removal and installation unit for the ballast. Thus, according to the invention for both separate Schotterausbaueinheiten as well as separate Schottereinbaueinheiten different types a cleaning option for the ballast within a Arbeitswagenverbundes created in the sense that this way a modular refurbishment of the materials is possible, regardless of the technique, which the removal and installation of materials, such as gravel , makes. This creates a cleaning for various applications in modular use. By this procedure, for example, the gravel removal and bulkhead installation by means of an excavator in front of head, but also with complex removal and installation units can be made variable and cost-oriented. Depending on the requirement of the working speed within the Baufensters can then always be chosen the cheapest option for the work to be performed. Another advantage of the invention modified by the work vehicle is that both purified gravel and incurred in the cleaning disposal shares can be better logistically separated and bunkered on the track appropriate for use. The work trolley according to the invention is thus classified as a refurbishment trolley in a series of conventional MFS wagons. The invention protection extends both to the work car in the form of the cleaning module according to the invention for the ranking within a car network per se, but also to the thus created modular cleaning train with its modular cleaning option. The modified working car according to the invention is to be seen for the optional, separate track-bound and not track-bound removal and installation units for the ballast and / or the other substructure materials.

The modified work cart according to the invention with its reprocessing device can initially be designed in a basic version. This basic version takes over the basic processing of the material, which initially receives the material to be processed of the variable work group. Thus, in this basic version of the work cart, the material (especially ballast) can be expertly accessed by screening and classifying reuse. All technical solutions for screening, classifying, washing, drying, breaking, sharpening and other processes can be carried out in this work cart. About corresponding conveyor belts while the materials are supplied to the work trolley according to the invention and abandoned the reprocessing device. Therein, the desired operations are then performed to work up the ballast (or more generally the material) and make it available for further use.

In this way, a modular reprocessing device is created by integration into a work car in a simple way, which are classified in a Arbeitszugverband can. This can consist of all conceivable individual components, ie individual work cars and be strung as desired. Thus, a track-bound or track-independent work unit for removal and installation of the ballast can be provided with optional transfer trolley, also optional conventional MFS trolley for Zwischenbunkern the materials, also the cleaning module according to the invention, further optionally trained accordingly further work carts for washing and separation in lack of space Components in the basic version of the work cart according to the invention and finally more conventional MFS wagon for temporary storage of non-usable cleaning. After working up the materials (in particular the ballast), the reusable gravel after processing is fed to the car with the appropriate installation unit. The gravel is thereby incorporated as recycling gravel. If necessary, the reusable fines of the ballast cleaning can be added to the substructure layers, namely the gravel or surface protection layer, in an expanded optional form in a further processing module in the machine sequence.

Further conceivable variants and options are conceivable by attaching additional conveyor belts to the individual MFS wagons. Bottom conveyor belts with end-side transfer belts, roof conveyor belts with end transfer conveyor belts for optimal process-flow transport of the materials can be provided here. Furthermore, the individual modules can be electronically coupled to partially or fully automate the processes. Likewise, the material can be abandoned by any conceivable task unit, such as by simple excavators or milling, or also be rebuilt by means of excavators and rollers. It can thus take place in the head area of the work train, both the track-bound modular procedure as well as the track-bound. This depends only on the chosen technology for the removal and installation of materials at the expansion and installation location.

Likewise, the work cart according to the invention may have its own or a foreign drive for forward movement. This can be installed within a module within the machine series or also be classified as a separate drive unit within the ranking of the work car.

The work trolley according to the invention is, with its processing device for expanded gravel and / or other substructure materials - as already stated - queued in a series of further work trolleys (but of a different type) of the work train, the work trolley according to the invention having conveyor belts for transporting materials of these adjacent further work trolleys. By this is meant that on the work car according to the invention on both sides different type of work, such as MFS wagon or the like. Connect, with the need to transport the materials along the work train without the work trolley according to the invention with its processing device is an obstacle and interruption for this material transport and the material transport there increased. In this respect, this preferred development proposes that the materials can be transported to a certain extent without the work cart according to the invention being an obstacle with its reprocessing device.

As a result, a logistically flexibly expandable work cart in the form of a work-up module and / or cleaning module is created as a whole, which is based on the work trolley according to the invention. Thus, the logistical possibilities of the work trolley according to the invention are so extended that the material flows can be performed by the work trolley according to the invention with its modular cleaning and processing technology, namely material flows associated with the work-up for developed ballast and / or other substructure materials in the work trolley according to the invention have nothing to do. The work trolley according to the invention with the cleaning and / or refurbishment module according to the invention thus becomes part of a flexible logistical transport and conveying path within a modular, flexibly configurable train. It is thus possible, within an arbitrarily lined train of material-handling silo wagon or the like. To queue the work cart according to the invention with its reprocessing device, without having in the sequence of work cars constraints in the material flow. As a result, the possible material delivery streams adjacent the material trolley can be variably guided by the logistic work trolley with the cleaning module such that the work trolley with its processing device also functions without a (simultaneous) cleaning performance as a pass-through module for the materials in all possible conveying directions of adjacent material trolleys.

The starting point is thus the cleaning module according to the invention as well as any further processing module for the ranking within a carriage assembly made of MFS wagon or the like in conjunction with the modular logistical extension for cleaning and / or refurbishment services with a modular cleaning train / refurbishment train. The extension can have modular washing, screening and refurbishment modules, etc., including the optionally used for the modular cleaning unit track-bound (or non-tracked) removal and installation unit. Due to the additional features of the work cart according to the invention with corresponding conveyor belts is the Adjustment of the work cart according to the invention within an arbitrarily lined train with material trolley possible. As a result, any number of modules of this type can be set in the conveyor line of MFS cars or the like, without hindering or impairing the flow rate through their function. Thus, any sequence of different machine technology in a modular system within a composite of material trolley is possible without negative influences and constraints on the material flows of the adjacent and lined material trolley to have. This allows in many ways entirely new possibilities of machine assortments and logistic applications in the track construction sector with modular technology.

Finally, the conveyor belts of the work trolley according to the invention are used for transporting the materials. These conveyor belts of the work car are reversibly operable. This means that the conveyor belts of the work carriage according to the invention which are already present are used for the transport of the materials. In this case, the operation of the reprocessing device can be interrupted.

A further development proposes various possibilities of the processing device for ballast. The reprocessing device can accordingly be designed for the cleaning and / or washing and / or drying and / or screening and / or classifying and / or breaking and / or sharpening of ballast.

Furthermore, it can be provided that the work car has an intermediate conveyor belt in the middle region. With this intermediate conveyor belt, it is possible to transport material in particular from the reprocessing device to the roof conveyor belt. Similarly, it is also conceivable to transport material from the roof area in the floor area of the work car. This intermediate conveyor belt further improves and optimizes material logistics.

Furthermore, a development proposes that the reprocessing device is either permanently arranged on the work car or is detachably arranged. The reprocessing device can thus consist of a compact built, stand-alone machine or work car. Alternatively, the system can also consist of a conventional standard railcar with a so-called Hukepackreinigungsmodul. This means that in this last-mentioned alternative, a cleaning module available on the market (for example in the form of a mobile crushing and sieving plant or other modules) is reconstructed from the shape and the weight such that it acts as loading volume on a standard railcar can be saddled up and used as a cleaning module in track construction for the modular basic machine according to the invention. However, this module, which was then redesigned as a loading module for the railway wagon, can (in contrast to the permanent modular compact module) also be uncoupled and made available for further uses in the trackless sector. This Hukepackalternative thus has optional other uses in the trackless area, which can lead to significant deployment extensions. The Hukepack alternative can be used for all cleaning and washing module solutions.

According to a further development, the work trolley according to the invention can be classified with its reprocessing device or its reprocessing either in the row of other work cars of the work train or the work trolley according to the invention is designed as a head work car. When using the work cart according to the invention as a head cleaning module this may have a hopper for the material to be processed. This feeding hopper, from which the removed ballast and / or other substructure materials can be supplied to the processing device via one of the conveyor belts, can be retractable and / or foldable. This feed hopper or the overhead work cart, the material by means of a loading unit (eg excavator or tiller) or by means of a loading station abandoned. Overall, therefore, the work cart according to the invention with the reprocessing device can be modular in a train train einreihbar or - be extended with a hopper - performed for work on the head. For example, the hopper may be detachable so that the cleaning cart is either in front of the head (with hopper attached) or in line with the other cart (then without hopper).

Furthermore, additional conveyor belts are provided for transporting the materials, namely floor conveyor belts, roof conveyor belts and transfer conveyor belts in the end areas. The conveyor belts can basically be single-row or preferably multi-row. This basically applies to all conveyor belts of the work train.

A further development proposes the use of different types of conveyor belts, namely simple conveyor belts or split conveyor belts.

Yet another embodiment proposes that the modular work cart according to the invention (in the manner of a locomotive) can be used as a tractor modular in the train. This has the advantage when in particular large vehicle networks must be moved.

A first embodiment of a work train according to the invention for the rehabilitation of a substructure as well as a railway track, refers to a work train having a plurality of juxtaposed work car, of which at least one work car an inventive work car with reprocessing device, which at any Reihungsort in an arbitrary sequence of further work cars without reprocessing device is queued within a work train.

A preferred development provides that different work cars of the type according to the invention are provided for different types of workup of the ballast and / or the other substructure materials. The particular advantage is that the modular character of the individual work cars is promoted. The basic version of the work trolley according to the invention serves the basic processing of the material. Optionally connected further, special work trolley according to the invention can then serve for further processing steps. These special work cars can be combined in different ways and placed in a row. Thus, in addition to the basic version of the work trolley according to the invention, one or more additional cars are added. This creates a high specification in terms of modular design. Thus, in the basic version, the work cart according to the invention can screen and classify the recorded material and thus make it available for reuse. In an additional car, the materials can optionally be washed and separated, for example, in the case of space shortage of the components in the work cart of the basic version. Depending on the design of the additional car is thereby created a high degree of individuality in the sense that the base module can be extended by one or more additional car modules that can serve the outsourcing of cleaning and laundry and other work. The entire system can be designed arbitrarily and serves, inter alia, the space extension for the basic module according to the invention of the work car. This advanced workup can thus involve a variety of steps, such as washing and sieving the ballast. But other treatment methods such as breaking or sharpening of the ballast can be done here as steps in one or more modules.

It is also conceivable, reusable fines of the ballast cleaning if necessary in a corresponding processing module of the work cart, for example, the subbing layers, especially the gravel or layer protection layer to mix. In this optional work-up step in a suitably trained work vehicle, soil improvement measures can additionally be carried out. By adding soil conditioners and additives, a specific recipe 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 machine can thus achieve a maximum utilization of all expansion materials by expansion modules in appropriate separate work car with flexible and needs-based use. Only the pure waste materials must be removed and disposed of in the maximum stage of expansion of the machine.

According to a further development, the work trolley according to the invention can be queued with his reprocessing or reprocessing either in the row of other work cars of the work train or the work trolley according to the invention is designed as a headwork car of the work train.

Furthermore, it can be provided that the work cart in the modular system is intended and designed both for track-bound and for track-independent removal and installation units for ballast and / or other substructure materials. This creates a universal and, above all, modular system for the removal and installation of materials.

Another development proposes that the modular work cart according to the invention can be used as a separate work unit for ballast and / or other soil materials. Thus, the work car can be used as a work unit behind a self-propelled or non-propelled, combined or un-combined disassembly and assembly device for ballast and / or other soil materials.

Furthermore, by a further development, the ranking and supply / removal of new material and waste material in one and the same material trolley / work car allows by the work car is used as a transition point for an endless material cycle between an expansion unit and an installation unit for gravel and / or other soil materials. This further improves the logistics of the materials.

A further development proposes the control and technical connection of the modular work cart according to the invention in series with the other work cars of the work train. This means that the modular work cart according to the invention is integrated into the overall electronic logistics of the work train.

A further development of this suggests that the electronic connections are provided for the automation of processes of the individual work cars in the entire train or work organization.

Finally, a further development proposes that when using a modular removal and installation device for the ballast together with the modular cleaning module according to the invention work cart with processing device for the ballast, the working direction of the Gesamtverbandes the work train is arbitrary.

An embodiment of a use according to the invention of a work trolley according to the invention in a work train for rehabilitation of the railway track consisting of a substructure and of a track, wherein gravel and / or other substructure materials are not removed and rebuilt by the work trolley, provides that with respect to their transport direction reversibly running conveyor belts of the work cart optionally the removed gravel and / or other substructure materials of the reprocessing of the work car are supplied and then recycled materials are completely or partially rebuilt or transported away, or materials of the neighboring other work cars are transported through the work car.

A further development proposes the logistics for the reusable components and for the non-reusable components of the reclaimed ballast and / or other substructure materials. So the waste material (undersize and dirt) is handed over to the conventional MFS wagon for transport. After processing, the cleaned substances and the waste materials are discharged from the car in different directions. Thus, the usable material is provided in one direction, while in the other direction of the non-usable portion is discharged.

In another development, the modular work cart according to the invention is integrated in the total transport of the ballast (processed old ballast and Neuschotter) to a removal device or a built-in device with. It can by means of the work car the supply of the old ballot and the Neuschotters done simultaneously. Overall, this means optimal logistics for the supply of the ballast.

Furthermore, it can be provided that during the processing of the ballast and / or other substructure materials resulting fines or non-recyclable substances are improved and worked up by the addition of aggregates. Such improvers may be lime or cement. Other improvers or enhancers are conceivable. As a result of this workup, the materials that are initially not usable can then be reused accordingly and thus enter into the recycling cycle. This improvement and processing of the substances takes place in particular in a separate work car.

A method according to the invention provides for the operation of a work train according to the invention with a work car for the rehabilitation of a railway line consisting of a substructure and of a track, whereby gravel and / or other substructure materials are not removed and re-installed by the work trolley according to the invention. The method comprises the steps that fed by the reversibly executed with respect to their transport conveyor belts of the work cart developed gravel and / or other substructure materials of the reprocessing of the work car and from there then the processed materials are fully or partially reincorporated or removed or the materials of the other adjacent Work car to be transported through the work car.

The features in the dependent claims represent independent inventions, regardless of the subject of the main claim.

The continuously moving work train during work Fig. 1 initially has a work car 1 for removal and installation of ballast 10 of the railway line. This ballast 10 is part of the substructure 11 for the track 12. The work vehicle 1 follows - optionally - a transfer car 2 for the ballast 10th

The transfer trolley 2 is optionally followed by conventional material-conveying silo trolleys 3, 4 (so-called MFS trolleys) or the like. The MFS trolleys are not to be understood as limiting. It can also be other work cars.

The MFS trolleys 3, 4 serve on the one hand for the transport of the materials and on the other for the intermediate bunkering of materials. These MFS cars 3, 4 each have one or more floor conveyor belts 13. In the exemplary embodiment shown, one end of the MFS carriage 3, 4 has a transfer conveyor belt 14. This is pivotable about a horizontal axis. In principle, such pivotable transfer conveyor belts 14 can also be provided at both ends of the MFS wagon 3, 4. These can also be telescopic in the horizontal direction, wherein the pivotable portion of the transfer belts 14 is bent over the horizontal part upwards. Also, the transfer conveyor belts 14 may be pivotable about a vertical axis. Furthermore, the two MFS cars 3, 4 have roof conveyor belts 15. These also have end pivotable transfer conveyor belts 16.

The difference between these work cars 5, 6 to the above MFS cars 3, 4 is that the two work cars 5, 6 a reprocessing device 17 for dismounted ballast 10 (or generally for dismantled or otherwise Substructure materials). In this case, the two work cars 5, 6 are identical in their basic concept, but differently designed with regard to the workup devices 17. Here, the work cart 6 defines with its reprocessing device 17 a basic version and the work car 5 with its reprocessing device 17 an additional version.

Finally, follow in this embodiment, two more - conventional - material handling silo wagons 7, 8 (MFS cars). These have - in the embodiment - turn Bottom conveyor belts 13 with transfer conveyors 14, but no roof conveyors on.

This illustrated compilation of the car is purely exemplary. Other compilations of the car are of course possible.

The operation is as follows:

After passing the transfer car 2, the transport of the ballast 10 takes place by means of the roof conveyor belts 15 of the two MFS cars 3, 4, to the work car 6. There, the gravel of the reprocessing device 17 of this Work cart 6 supplied, which represents the basic version. Here is a basic workup of the supplied ballast 10. From there, the pre-processed ballast 10 of the processing device 17 of the second work vehicle 5 is supplied, where further processing steps take place.

The processed ballast is returned to the work car 1 via the bottom conveyor belts 13. This builds the recycled gravel 10.

By contrast, the waste materials are transported in the opposite direction and reach the area of the bottom conveyor belts 13 of the MFS carriages 7, 8.

The variant in Fig. 2a shows the work car 6a in a compact design, in which the reprocessing device 17 is solid and insoluble and thus made compact with the undercarriage as a unit. This means that the reprocessing device 17 is not intended to be removed from the undercarriage. Rather, in this work car 6a is the basic idea that the reprocessing device 17 remains permanently on the undercarriage.

An alternative to this shows Fig. 2b , In the work vehicle 6b shown there, the reprocessing device 17 is removable, that is releasable. This means that the reprocessing device 17 is removed with its functional cleaning unit and can be used for other, not track-bound purposes. Thus, the reprocessing device 17 can be removed from the undercarriage and placed, for example, in a central ballast processing plant and used there. In this case, either the entire work module or only a partial work module can be removed from the undercarriage. The representation in Fig. 2b shows the undercarriage without conveyor belts (there is the reprocessing facility 17 provided with conveyor belts), while in the presentation below the undercarriage has conveyor belts (where the detachable reprocessing device 17 then no conveyor belts).

Fig. 3a to 3c Finally, the use of the work cart 6 with its reprocessing device 7 in the use as a head work cart (while in the previous embodiments of the work car 5, 6 is ranked in the row of work cars of the work train). This cleaning module when used on the head has a retractable or retractable feeding hopper 18. This hopper 18 can be grown on the car.

Fig. 3a shows the feeding hopper 18 in the extended position, so that by means of a loading unit (for example, excavator or milling machine) or by means of a loading station, the material, in particular the ballast, the hopper 18 can be abandoned. From there, the material is then fed via a roof conveyor belt (but it can also be another conveyor belt) of the reprocessing device 17. Fig. 3b shows the feeding hopper 18 in the retracted state and Fig. 3c the hopper 18 in the dumped state.

Fig. 4 shows a modified embodiment of the work train. In this case, the carriages 5, 6 according to the invention for refurbishing the ballast, etc. are modified, while the remaining work cars have remained the same.

As in Fig. 5 can be seen, there is the difference of the work carriage 6 according to the invention in comparison to the work car 6 of the work train in Fig. 1 in that the work cart 6 is suitable for transporting materials from the MFS carriages 3, 4 on one side to the MFS carriages 7, 8 on the other side (and vice versa). For this purpose, the work cart 6 - as before - an upper floor conveyor belt 19 'and at a distance below a lower floor conveyor 19 "on, further end transfer belts 20 which are pivotable downwards and upwards and retractable on a carriage and extendable and possibly Furthermore, in the roof area, a roof conveyor belt 21, which is each bent at the end pivotably, and finally in the roof area a transfer conveyor belt 22, which can also be bent upwards and downwards at the ends.

The operation is as follows:

Fig. 6a shows the work car 6 in its actual task, namely the processing of broken gravel 10 (or any other conversion material). This cleaning module fulfills its basic task. This corresponds to the operation of the work carriage 6 of the above-described output variant of the work train.

The work cart 6 takes up the material to be worked up the variable work group. The material is in this case 6 professionally made available by reusing sieving, classifying etc. in this work car. In this case, all technical solutions for screening, classifying, washing, drying and other operations can be performed in this work car 6.

The material is fed via the roof conveyor belts 21 of the cleaning unit and abandoned the processing unit of the cleaning module. In these units, the above-described operations are carried out to - as stated - to make the ballast 10 a utilization accessible. After this processing, the cleaned substances and the waste materials are discharged in different directions from the car. The cleaned, reusable substances are discharged via the upper bottom conveyor belt 19 'and then via the right transfer conveyor belt 20, while the waste materials are discharged via the lower bottom conveyor belt 19 "and via the left transfer belt 20 of the work cart 6. Pickup vehicles are the adjacent MFS cars or the like.

Specifically, the supplied ballast 10 is first fed by means of roof conveyor belts 21 a Vorsiebeinheit at which the undersize is separated from the coarse grain. The coarse grain is then fed via a Vorsiebeinheit which by vibration and movements as well as by the geometric arrangement also has a transportability, a stone crusher (eg baffle or cone cup). In this quarry plant, the grain is processed. It is cleaned again by striking and breaking, if necessary, sharpened and / or crushed. After the operation in the rock crushing plant, the material is fractionated through a second screening unit into the end products. In this case, the unusable fine grain is fed to the lower bottom conveyor belt 19 "and the usable grain is fed to the upper bottom conveyor belt 19. In addition, a washing by spraying with water can be carried out here on the preliminary screen and the after-sieve. to the transfer conveyors 20. The unusable grain is transferred to adjacent material trolleys while the reusable grain (eg, recycled ballast) is transferred to the adjacent material trolley or a modular paving unit.

By the manner described above, a modular cleaning unit is provided in a simple manner, which can be lined up in a train of material-conveying silo wagon or the like. The machines can here - as stated - from all conceivable individual components, eg. As cleaning modules, washing modules, soil improvement modules, etc. exist and are lined up as desired before and after the cleaning unit.

However, the work cart 6 is not limited to the above-described workup work for excavated ballast and / or other substructure materials. The work cart 6 has additional logistical functions. The core idea lies in the extended conversion and transport options. In order to use the cleaning technology / processing technology within a train of MFS cars or the like. As a logistics hub for flowing and overflowing materials, extensions of the modular workbench 6 are necessary.

First, the conveyor belts, namely the upper floor conveyor belt 19 ', the lower floor conveyor belt 19 ", the transfer conveyor belts 20, the roof conveyor belt 21 and the transfer belt 22 in the roof area are each reversibly designed, which means that the operating directions of the conveyor belts exceed the" normal "use for the performance of the cleaning modules can be changed out in their transport direction.

Furthermore, the transfer conveyor belts 20 are designed as retractable conveyor belts. This means that they can be changed via a joint in their angle of attack and thus in their position. These transfer conveyors 20 can be retracted in their horizontal position below the processing unit in a kind of sandwich bottom below the lower bottom conveyor belt 19 "(as shown in the illustration in Fig. 6b can be seen in the left transfer conveyor belt 20).

Furthermore, a reversible and / or displaceable transfer belt 22 in the form of a bypass short strip is assigned to the already existing, but now reversible roof conveyor belt 21.

Furthermore, the upper floor conveyor belt 19 'in its end position is optionally displaceable and / or bent, so as to ensure the reversing and the delivery in both directions.

If required, finally, in each case optionally also several bands in the depth of the work carriage 6 are mounted side by side. This would, for example, for further material flows with adjacent material trolley, which have two or three Bypaßbänder or basic bands work, advantage. These options do not matter here.

In principle, this modular logistic machine technology makes it possible to flexibly redirect and transfer the material flows which run to the work cart 6 and run off the work cart 6, without the work cart 6 being restricted to the processing of removed materials. The additional benefit is thus in the additional logistical possibilities for the transport of materials. Specifically, an independent of the workup conveyance and diversion of material flows of any kind is possible. This allows completely new working concepts and series for the promotion of material flows within the train of MFS wagons or the like. The individual components of the train may be: track-bound and track-bound working units for removal and installation of the ballast, further optional transfer trolley, further optional material conveyor Silo wagon or the like. For the intermediate bunker requirement, further optional (inventive) work carts for washing and separation in space shortage of the components in the work cart 6 according to the invention as its extension, further cleaning modules according to the invention with logistics extension for flow through and over the work cart 6 of the invention and finally other material handling silo wagons or the like for temporary storage of non-usable cleaning goods or other transport services.

Fig. 6b now shows a first variant of the logistical extension of the work car 6. As a comparison to Fig. 6a shows, the conveyor belts are repositioned accordingly. Specifically, material from the adjacent MFS car 7 via its transfer conveyor belt and a task unit 23 to the - in this case - lower bottom conveyor 19 "fed, which compared to the operation in Fig. 6a now transported in the opposite direction. The upper floor conveyor 19 'releases the material to the extended transfer conveyor 20, which transfers the material to an adjacent MFS cart or the like. In this way, material can be conveyed through the modular cleaning unit / processing unit in a desired working direction and transferred to a material trolley or any working unit in front of or behind the modular cleaning unit / processing unit.

Fig. 6c shows a further operation of the work carriage 6 according to the invention, namely the transport of the material in the drawing from right to left. Here, the material is supplied to the reversible roof conveyor 21 via a transfer belt of an adjacent MFS truck or the like. This leads the material to the reversible and / or displaceable and / or bendable transfer conveyor belt 22. This serves to bridge the task points of the reprocessing modules. The transfer conveyor belt 22 can be adjusted in its position and its direction so that it can be used for these purposes. From the transfer conveyor belt 22 then passes the material to be conveyed on a corresponding conveyor belt of an adjacent MFS wagon or other working module.

Fig. 6d finally shows in comparison to Fig. 6c the reverse direction by means of the conveyor belts by corresponding repositioning.

Fig. 7 shows a modified embodiment of the work train, namely with a modified embodiment of the invention of the trolley 6 for processing the ballast 10. More detailed illustrations with regard to the material flow, namely the ballast 10 show in particular the Fig. 8b and Fig. 8c ,

This shows first Fig. 7 in that a material reversal from the roof area to the floor area with reversed material flow direction in the sense of a material cycle is provided in the MFS carriage 8.

A special feature of this work cart 6 is that in the central region of the work carriage 6, an intermediate conveyor belt 24 is provided. In addition, the previously described conveyor belts are still provided in the floor area and in the roof area including transfer conveyors.

The intermediate conveyor 24, as it is in Fig. 8b is shown there is in a kind of rest position in which it is not involved in the transport of the ballast 10. As in particular in comparison with the representation in Fig. 8c can be seen, the intermediate conveyor belt 24 on the end transfer conveyor belts, which are pivotable upwards and downwards. This shows Fig. 8c the situation in which the intermediate conveyor belt 24 picks up the ballast from the reprocessing device 17 and transports it to the roof conveyor belt 21 of the work car 6. For this purpose, this roof conveyor belt 21 is not formed continuously with respect to the longitudinal extent of the work carriage 6, but it is divided into two individual roof conveyor belts 21, wherein the respective ends can be pivoted downwards and upwards. In this way, a transfer of the ballast by means of the intermediate conveyor belt 24 to the in Fig. 8c right roof conveyor 21 possible. In principle, the roof conveyor 21 can also be divided into three or even more sections.

Furthermore, in Fig. 8b recognizable that the cleaned ballast can be discharged via the end transfer conveyor belt 20. Fig. 8c however, the situation in the same area shows how material is transported through the work car 6 (from right to left in the drawing). Also, in this drawings further streams of material can be seen.

Fig. 9a to 9c shows a further modification of the material flow (indicated by the circle). These modifications show how the tape guides can be used in a variety of ways to accomplish the desired transport path of the materials. This merely represents another example of conveyor belt logistics. Further variants for transporting the materials in the floor area and / or in the roof area are conceivable and possible.

The work train in Fig. 10 Finally, in principle, it corresponds to the work process as defined in Fig. 7 is shown. The difference is that the working direction is opposite. This is in contrast to existing systems. As a result, the work cars always drive on a finished track (old track) and are not subject to the same as in the existing systems of driving a Baugleises.

As already mentioned, additional conveyor belts can be attached to the above-described individual components. These correspond in their sequence-technical functions to the already mentioned conveyor belts. They have the advantage that the number of fabric layers and material flows that are available for an execution performance is increased. Thus, a variant with two adjacent bands is conceivable. However, the number of bands can hereby be supplemented arbitrarily according to the available space. So two or three or more bands can be arranged side by side.

Furthermore, the individual modules can be electronically coupled to supply the operations of a partial or full automation of the individual components of the machine network.

Furthermore, the conveyor belts can be additionally equipped with a water spray for dust prevention. The feeding of the water spray can be done here by a separate water truck or by a water tank, which is assigned to the work car. The bushing has the purpose of dust binding on the belts and can optionally be made and installed anywhere on the individual conveyor belts.

Finally, the conveyor belts can be additionally provided with an enclosure against dust.

All cleaning units or other processing units or associated loading or unloading stations (here also separate wagons) can be used both track-bound on rail bogies as well as chain undercarriages (or in combination) and operated.
