Abstract

To provide a variety of types of loose bulk materials at the working site, where ballasts of different grades are required at the railway permanent way, they are loaded in charges simultaneously or in sequence at the transport/storage freight wagons (11), to be taken to or next to the permanent way location in a rake (80) of permanent way maintenance wagons. The bulk materials are classified and separated into fractions according to their use. The materials are moved and transferred by conveyors in and between the wagons.

Description

The invention relates to a method for supplying a construction site with Building materials in the form of diverse, at the construction site at the same time or / and bulk materials needed in succession. It is, for example, on the supply of track construction sites with track construction materials, for example with gravel material, on the one hand, and PSS material (for example in shape a mixture of round grain material and sand), on the other hand. At the site required, to be provided by the method Bulk solids may be homogeneous uniform or homogeneously mixed Bulk goods of uniform or different constituents act. The respective bulk material can therefore from different Bulk materials may be mixed together (such as sand and round grain or gravel of different particle size ranges) or only one bulk material include (for example, only sand or only gravel of a grain size range).

Conventionally, such building materials are separated from each other Construction site transported, with a great logistical effort, if different materials in a certain ratio needed to each other. This is clear from the following example:

When planning improvements in track construction, ballast and PSS material in particular must be transported to the track construction site as new materials, as long as it is not possible to reuse old material through material recycling on site. If you want to achieve an hourly output of 100 meters of track in accordance with an ambitious goal, you will need, for example, 250 m ^{3 of} ballast and 450m ³ PSS material per hour of new substances. With a shift duration of, for example, 12 hours, approximately 8,400 m ^{3 of} new substances are needed, which must be transported via the working track to the track construction site (construction tip), since an existing operating track for rail traffic is still needed. Supplying such quantities of material in the required material ratios to the track construction site is a difficult logistical problem and, if at all, possible only with the use of a very difficult and labor intensive logistical chain with a high capital outlay to provide special transport and silo wagons, especially possibly based on railways Conveyor and Silo Waggons, in the filed on 12.04.2001 to the Applicant GSG Knape Gleissanierung GmbH German non-prepublished patent application "Rail transport and silo wagon, transport train and method for receiving, caching and delivery of materials in connection with track construction ", official file reference 101 18 393.3, are described. These conveyor and silo wagons allow the simultaneous, separate feeding and removal of at least two different materials or fractions of matter to a track construction site.

EP-A-0303037 discloses a method for supplying a Construction site with building materials.

Based on conventional conveyance and silo wagons and conventional Transport and delivery logistics, approximately according to the teachings of Patent DE 32 19 025 C2 and EP 0 096 236 B2, but it appears impossible to achieve a desired hourly performance as mentioned. In particular, it is based on a conventional filling of material silos based on the materials Bucket wagons and gantry cranes for transferring the material from the Buckets on conveyor belts or in the silos, not possible, essential to supply more material to the construction site than for one meter of about 30 meters per hour is needed. An increase in the number of used Gantry cranes may be due to the then higher number of shunting operations bring no significant performance increase. An enlargement The capacity of the bucket (enlargement of the bucket) is in view of the Axle loads on the drive-over bridges between the bucket wagons not possible.

• Verladen, nacheinander oder gleichzeitig, jeweiliger Schüttgutmengen einer Mehrzahl verschiedenartiger Schüttgüter,
• Transportieren, nacheinander oder gleichzeitig, der verladenen Schüttgutmengen zu der Baustelle oder zu einer dieser benachbarten Stelle,
• Klassifizieren und - entsprechend der Klassifizierung - Fraktionieren der herantransportierten Schüttgutmengen nach wenigstens einer Schüttguteigenschaft, ggf. Korngrößen oder Körngrößenbereiche,
• Bereitstellen und ggf. Zwischenspeichern von der Klassifizierung entsprechenden Schüttgutfraktionen in Zuordnung zu der Baustelle.

In contrast, the invention proposes to move away from the previous premise that the various required bulk materials are transported independently of one another and, as it were, sorted "sorted" to the construction site, even if this results in additional expense for material separation at the construction site. The invention as defined by claim 1 proposes for the aforementioned method that this comprises at least the following steps:

• Loading, one after the other or at the same time, respective quantities of bulk material of a plurality of different types of bulk materials,
• Transporting, one after the other or at the same time, the quantities of bulk cargo loaded to the construction site or to one of these adjacent sites,
• Classifying and, according to the classification, fractionating the quantities of bulk material transported by at least one bulk material property, optionally particle sizes or particle size ranges,
• Provision and, if necessary, temporary storage of bulk material fractions corresponding to the classification in association with the construction site.

In the context of the invention, it is the various bulk materials in the state in principle, any mixing or non-mixing to load and transport, so that it is comparatively low logistical Effort is possible, large amounts of different materials to be loaded and transported to the construction site or to promote. The at the Construction site at the same time and / or successively required bulk goods then only on the basis of the classification and possibly fractionation of provided transported bulk quantities allocated to the site and possibly cached.

The invention is based on the consideration that the ratio of is often known and then often at least for certain construction sections remains the same. This makes it possible, for example, from Plant or a loading point the required, regularly homogeneous New substances (eg gravel and PSS) in the desired ratio to loaded, if necessary in a mixed state or simply by entering of bulk quantities of the bulk goods in question one after the other Container or means of transport (for example, a number of wheel loader bucket loads a first bulk material and a number of wheel loader bucket loads a second bulk material). The in the container or Transport materials contained materials can then go to the construction site or transported or promoted this neighboring place and the Bulk materials are then classified before installation at the construction site and fractionated, ie separated again, for example by sieving.

In connection with a track construction site can be transported to and feeding the materials advantageous from the patents DE 32 19 025 C2 and EP 0 096 236 B2 known conveying and silo wagons can be used, and it can be particularly advantageous a conveyor and Transport logistics realized according to the teaching of these patents become. Thus, after the emptying of the further away from the track construction site Conveyor and silo wagons pulled this over the track and refilled become. In the meantime, they are getting closer to the track construction site Conveyor and silo wagons emptied. The refilled conveyor and silo wagons are coupled back to the transport train, and the material is due to the meantime emptied, remaining in the transport train Conveying and silo wagons conveyed and from the track construction site next not yet completely emptied conveying and silo wagon dammed up again. This type of conveyor and transport logistics is from the mentioned patents known per se, but it has not been in Considered this transport and conveyor logistics at several various, more or less mixed building materials because of obvious reasons so far It is assumed that it is nonsensical, different materials from each other to transport and deliver unseparated, since this is the case Mandatory separation of the materials after delivery requires corresponding mechanical effort and thus cost.

Further considerations have led to the realization that it is in practice is not necessary, the various bulk materials with a the Relative need to transport the construction site exactly corresponding ratio and the construction site. So after the breakup the materials, for example, by a sieve the materials For example, transfer by means of transfer tapes to respective silos be and be cached there, so that the site as needed can be supplied with the required materials, too if in a supplied subset the required materials are not in the Target ratio present or a subset even only of the bulk material a variety is formed. As silos, in particular those mentioned in described on 12.04.2001 German patent application Conveying and silo wagons with at least two transport boxes advantageous can be used, which optionally have a separate Caching of the bulk material fractions or the required bulk materials and promoting them towards the track construction site, in particular to a mounting device allow. Through this caching option For example, one could be used for procurement conventional conveyor and silo wagon according to the patents DE 32 19 025 C2 and EP 0 096 236 B2 to a part, about half, with one material and the other part, say the other half, with one be filled with other material, for example, half with PSS material and the other half with gravel material. Also, for example such a conveyor and silo wagon completely with ballast material and another or more other such production and silo wagons each completely filled with PSS material. The relevant materials are then according to the teaching of these patents along the Chain of conveying and silo wagons conveyed towards the track construction site and a Trennanläge, in particular screen, led to to provide the individual materials. Material supply problems at the Installation points may be due to the intermediate storage of the bulk material fractions do not arise.

So it is possible, exactly mixed, inaccurately mixed, homogeneously mixed, unhomogenously mixed and unmixed quantities of material, for example by means of said conventional conveyor and silo wagons as a feeder, because the classification and - so far required - fractionation (separation, in particular screening) for the Provision of the required bulk fractions, where appropriate, for a separate homogenization of the bulk material fractions are ensured can.

Excess, currently not needed at the construction site new substances can in the mentioned silos or conveyance and silo waggons after the German do not publish Patent application dated 12.04.2001 be stored. However, it is extremely convenient if the total procured Materials the need ratio (installation ratio) of the required Bulk goods at the construction site at least roughly correspond to with a comparatively small cache capacity and no Unused new material to be removed from the construction site again. A exact premixing of the material but, as stated, not necessary which is also very advantageous in that often materials from various factories, loading points or manufacturers brought Need to become.

In the above explanations it has been assumed that at least one, preferably all of the bulk material fractions provided directly corresponds to a respective bulk material required at the construction site or correspond. This is not mandatory. One can also provide that at least two of the bulk material fractions provided be mixed together to a respective, at the construction site needed Provide bulk material and cache if necessary. The at the construction site be simultaneously or / and sequentially required bulk materials So after this training proposal only from the provided Bulk material fractions produced, namely mixed together. It can then in a sense, a production step are relocated to the site, the conventionally takes place in the manufacturing plant of a building materials manufacturer. Insofar as the required bulk goods are only produced close to the construction site (mixed together) be opened up, the possibility that no longer Bulk quantities are loaded and transported as such at the construction site are suitable for installation, but that in the case of Building materials mixed together from different bulk materials are, the originating bulk materials, such as sand and round grain in the Trap of PSS material, loaded according to the invention proposal and transported and that after providing appropriate Bulk fractions after classification and fractionation the needed Mixing material (in the example PSS material) according to the training proposal first produced, namely mixed together and - as far as required - homogenized.

In this context, one is thinking about the composition the various materials needed at the construction site. So it may be appropriate to avoid a big one Classification and fractionation effort of conventional formulations to deviate to one or more provided bulk fractions Merging of various bulk materials, for example to use gravel and other PSS material. So could Remember, for the PSS material instead of the usual round grain to use small-grained gravel material of a corresponding gravel fraction.

It is suggested that the transported bulk quantities in a classifier and fractionator are entered on at least one property, possibly particle sizes or grain size ranges, of the input bulk material and the entered bulk material classified according to the at least one property and - as required - fractionated and classified bulk fractions emits. It is especially thought that the classifying and Fractionator comprises at least one screen assembly according to At least one sieve characteristic undergoes at least one screening of bulk material and - depending on the composition of the bulk material in terms of Sieve curve - the bulk material in at least one, regularly at least transferred two bulk material fractions.

As has already become clear from the explanations above, it is within the framework of the Invention that the transported bulk amounts regardless of the Classification of a respective subset classified, in particular be subjected to at least one screening.

It has already been suggested that the bulk quantities at least partially can be loaded as a mixture of the bulk goods in question. Furthermore, it has already been suggested that the bulk quantities at least roughly loaded according to at least one requirement and possibly mixed can be, with the need ratio indicating in which Ratio of bulk materials needed at the construction site.

It was above the invention already in terms of track construction closer explained. An appropriate track construction site can be considered a line construction site which progresses along a line, namely the track. The Bulk quantities can then according to the invention along the line, namely, track bound on the track affected by the track construction site, the Track construction site to be supplied. In general, it is suggested that the construction site is a line construction site progressing along a line is, and that the bulk quantities or the required bulk materials along be fed to the line of the construction site. It gets for example thought that the line construction site is a road construction site and that the Bulk quantities or the required bulk materials of the road construction site road bound on the road affected by the road construction site be supplied.

Great benefits arise when the road is multi-lane and the Road construction site at least currently only a trace of several tracks the road is concerned. It is proposed for this purpose that the bulk quantities or the required bulk materials of the road construction site on this of the roadway affected track are fed so that the others Leave tracks for traffic. For example, the Road two have two and two traces, of which only one is affected by the construction while the other is for the normal Traffic without obstruction due to material supply for the construction site can be used.

The invention further relates to a railroad or road Classifying and fractionating device having one input area and several Having output ranges and having at least one property, If necessary, grain sizes or grain size ranges, one in the input area entered bulk material and the input bulk material after the at least one property classified and - according to the Classification - fractionated to the classification corresponding bulk fractions at the output areas.

Further, it is proposed that the classifying and fractionating at least one screen assembly designed for it is, according to at least one Siebkennlinie bulk material at least one Sieving and - depending on the composition of the bulk material in the Regarding the sieve characteristic - the bulk material in at least one, regularly to transfer at least two bulk material fractions.

The invention further relates to a transport chain for bulk material, comprising at least one classifying and fractionating device such as given above and at least one street-going or rail-mounted conveyor and silo wagon (possibly conveyor and silo wagon) for conveying and storing bulk material. It is in particular to a such car or wagon thought, at least one wageneigene Has (possibly wagon-own) receiving box for storage of bulk material is suitable and in a floor area a wageneigene Has (if necessary own wagon) material conveying device, whereby over at least a bulk goods receiving area from one end of the wagon (possibly wagon end) Bulk material can be introduced into the receiving box, into the Receiving box entered bulk material by means of the material conveyor along the conveyor and silo cart towards the other end of the car can be transported and at least one transfer device Bulk material at the other end of the car can be delivered from the receiving box, if necessary in an assigned bulk goods receiving area of an assigned further conveyor and silo wagon of appropriate design. It will be in case of track construction work, in particular, one, preferably several of the patents DE 32 19 025 C2 and EP 0 096 236 B2 known conveyor and silo wagons use.

The transport chain may be at least one off-road or rail Material dispensing device for dispensing on a road and Track construction site at the same time and / or bulk materials needed one after the other having, directly or indirectly, the classifier and fractionator connected. Furthermore, the transport chain a building or Treatment device for machine-supported road or track construction or have machine-assisted road or track handling, wherein the material delivery device of the construction or treatment facility is assigned by material supply.

The material delivery device may have at least one road-going or rail-based bulk storage device and / or at least a road-going or rail-wide bulk material mixing device be connected to the classifying and fractionating. It will open the above statements referenced.

As a bulk storage device can advantageously at least one road or rail-mounted conveyor and silo wagon (possibly conveying and transport) Silo wagon) for conveying and storing bulk material, which has several wagon-own (possibly wagon-own) receiving boxes, each suitable for storage of bulk material and in one Floor area have a respective carriage own material conveyor, wherein at least one respective bulk receiving area from one end of the wagon, bulk material in the respective receiving box can be entered, in the respective receiving box entered bulk material by means of the respective material conveyor along the conveyor and Silo wagon is transportable towards the other wagon end and via at least one respective transfer device bulk material at the other Wagenende from the receiving box can be issued, if necessary, in each case associated bulk receiving area of an associated further Conveying and silo wagon of appropriate design. It is used in the case of track construction especially thought to conveying and silo wagons of in the German patent application of the applicant of 12.04.2001 described Type in.

The invention particularly relates to a transport chain in the form of a rail transport train, possibly as a track treatment train.

The transport chain according to the invention (possibly the transport train or track treatment train) may be advantageous in the context of the method according to the invention used (used) to supply a construction site with building materials become. For that carried out using the transport chain In particular, it is proposed that the process be further developed at least one material transport wagon (possibly a material transport wagon) is used, simultaneously or successively and in the case of a larger or lasting material requirement also at least repeated two different building materials or building material fractions (hereafter exclusively called building materials) separated or unseparated, optionally mixed together, to a terminal Conveying and silo wagon (possibly conveyor and silo wagon) with at least transport a receiving box of the chain, and that the Building materials or the transported mixture material then in or a receiving box of this conveyor and silo wagon of whose one end of the car is passed forth and in the chain longitudinal direction transported over at least one such conveyor and silo wagon away is towards the construction site, the building materials or the Mixing material along a respective carriage through the material conveyor of the reception box towards the other end of the car is promoted and possibly from this end then by the transfer device of the receiving box in the receiving area of an associated Recording box of an immediately adjacent another such Conveyor and silo wagon is handed over, and where the building materials or the mixture material in at least one such conveying and Silo wagon is cached and according to the need for the materials to be transported to the site and finally the classifying and fractionating is supplied. In case of several successive conveyor and silo wagons (possibly conveyor and silo wagons) each with at least one conveying and receiving box is advantageous if for the intermediate storage of the building materials or the Mixing material first one of the construction site nearer car (possibly wagon) is filled.

Further, it is proposed that for caching the Building materials or the mixing material, the material along the straight to be filled conveyor and silo wagon by means of the conveyor the receiving box is promoted slower than at least one preceding and / or as - after delivery from the receiving box for Further transport towards the construction site - at least one subsequent one Conveying and silo wagon.

The material transport vehicle (possibly material transport wagon), for example a bucket transport wagon (possibly bucket transport wagon) with at least a material transport bucket or a similar conveyor and silo wagon (possibly conveyor and silo wagon) with at least one a conveyor having its own receiving box. Regarding the promotion and Silo wagons are especially thought to be waggons in the Patent DE 32 19 025 C2 and EP 0 096 236 B2 described To use species. But you can also waggons each with several Transport boxes according to the teaching submitted on 12.04.2001 Applicant's patent application, then the various Bulk quantities of each other undivided and possibly mixed in the receiving boxes loaded and possibly transported along the receiving boxes become. The given with these cars possibility, different Materials separated from each other and sort of sorted by means to transport and transport a wagon simultaneously is then the loading and transportation did not make use. This functionality of the new conveying and silo wagons after the mentioned application of 12.04.2001 but, as already explained above, advantageous after the classification and fractionation of the materials be used for caching.

In particular, it is proposed for the method that Classification and Fractionator provided bulk fractions or / and mixed bulk materials from each other separated into a respective associated receiving box of a plurality Receiving boxes having conveyor and silo wagon (possibly conveyor and Silo wagons) from the one end of the car (possibly wagon end) handed forth ago and in the chain longitudinal direction (possibly Zuglängsrichtung) over transported at least one such conveyor and silo wagon away be in the direction of the construction site, with the fractions or materials along a respective carriage (possibly wagons) through the material conveyor one receiving box towards the other Wagenende (possibly wagon end) are promoted and possibly by this End then by the transfer device of the respective receiving box in the receiving area of an associated receiving box one immediately adjacent further such conveyor and silo wagon (possibly wagons) are handed over, and where the fractions or materials in at least one of the conveyor and silo cars with several Recording boxes are cached and according to the Demand for the respective fraction or material in the direction be forwarded to the construction site.

In general, it will be appropriate that in case of several successive following conveyor and silo wagon (possibly wagons) each with several Recording boxes for temporary storage of fractions or materials First, one of the construction site closer car is filled. It is also proposed that for the intermediate storage of a fraction or a material this (s) along the currently to be filled conveyor and silo wagons by means of the conveyor of the fraction or the material receiving Receiving box is promoted more slowly than at least a preceding and / or as - after delivery from the receiving box for onward transport towards the construction site - at least a subsequent conveyor and silo wagon.

The content of the previously mentioned several times, submitted on 12.04.2001 Application 101 18 393.3 of the Applicant GSG Knape Gleissanierung GmbH with the title "Schienengängiger conveyor and silo wagon, Transportzug and methods of receiving, caching and dispensing of materials in connection with track construction work " European subsequent application is hereby incorporated by reference into Disclosure of the present application included.

It should be noted that it is part of the According to the invention, it can be provided that at least one of the bulk material fractions to be provided in association with the construction site after the classification and fractionation, if necessary after the at least one Screening, first subjected to a washing or dishwashing treatment, and then provided in association with the construction site (possibly line construction site) becomes. For this purpose, the classifying and Fractionator with a corresponding washing arrangement be executed. Another possibility is to have a separate track or road-going washing device to use, if necessary, the Transport chain according to the invention (or Transportzug or Track treatment train) is associated. It is on this on the 12.06.2001 submitted to the German Patent and Trademark Office German Patent Application No. 101 28 480.2 entitled "Method of Material washing or / and loam excretion concerning Bulk material in connection with construction work on a Line construction site and corresponding railways or road-going Attachment "or a European subsequent application referenced her Revelation by reference fully to the disclosure of is included in the present application.

Fig. 1 shows a trained as a conveyor and silo wagon railroad car 10, which in terms of its cross-sectional dimensions a predetermined Border profile 12 is sufficient. The wagon 10 has a vehicle frame 14 with Wagon side walls 16 on. The wagon frame 14 is on itself known manner on a plurality of bogies 18 each stored with several axles.

In a lower wagon area 20 are in the type of low-floor aggregates various drive devices for to be described below Material conveying, storage and transfer facilities arranged.

Above the lower wagon area is a material receptacle 24 held stationary in the vehicle frame 14, which has a bottom 26 and side walls 28 and together with a to the side walls 28th top subsequent section 30 of the side walls 16 a receiving box forms for bulk material. A bulk material level is exemplary indicated by the dashed line 32.

The bottom 26 of the receptacle has a known type and Way an upper strand of an endless conveyor belt, such as a scale belt, on, by means of which recorded in the receiving box 40 Material in carriage longitudinal direction can be promoted.

Above the receiving box 40, which is also referred to below as "lower receiving box" is called, is another ("upper") recording box 42, which also has a receptacle 44 with a bottom 46th and sidewalls 48. The upper receiving box 42 may also Pick up bulk material; a corresponding level is through the dashed line 50 indicated by way of example.

The bottom 46 of the upper receptacle 44 has corresponding Way an upper strand of a conveyor belt, such as a scale belt, on, for the promotion of the bulk material in wagon longitudinal direction serves.

The upper receptacle 44 is not stationary in the vehicle frame 14 arranged, but by an adjusting mechanism, not shown Hydraulic base height adjustable. Lower the upper receptacle 44 from, so increases the above the tub bottom 46 for storing material available space with appropriate reduction of above the tub bottom 26 of the lower receptacle 24 for storing material available space and vice versa. By height adjustment the upper receptacle so the material storage capacities of the upper and lower receiving boxes 40 and 42 be adjusted in opposite directions, which is a recording capacity enlarged and the other recording capacity is reduced.

It is assumed that in Fig. 1 concerning the upper receptacle 44 whose uppermost position in the vehicle frame 14 is shown. If you lower the receptacle 44, so can bulk over the level the upper edges of the well side walls 48 are heaped up, since side of the side walls 48 wagon stationary boundary walls 52nd are provided, in relation to FIG. 1 deeper adjustment positions the upper receptacle 44 whose side walls 48 up to a certain extent extend and together with the tub sides 48 the receiving box 42 laterally limit.

The upper receptacle 44 is together with a the tub supporting Intermediate frame 54 height-adjusted. The deepest adjustment position of upper receptacle 44 is through the upper edges of the side walls 28 of the lower receptacle 24 determined. The lower receiving box 40 then becomes substantially laterally only through the side walls 28 limited as a filling of the receiving box 40 above the level of upper edges of the side walls 28 in the lowest adjustment position of the upper receptacle to a significant extent no longer possible is.

In Fig. 1 it can be seen that relative to the boundary profile 12 above of transverse stiffening elements 60 of the vehicle frame 14 is still room. In this area, the upper end of a transfer and loading conveyor belt be arranged for the material transfer or filling of the upper receiving box 42 is used.

The conveying speed of the tub floor 26 associated conveyor belt on the one hand and the tub bottom 46 associated conveyor belt On the other hand, they are adjustable and independently adjustable. The conveyor belts can also be switched on and off independently of each other. As a rule, the belts are with the same conveying direction operate. But it can be useful for some situations if opposing conveying directions are provided or are adjustable.

The receiving boxes and their conveyor belts can each other independently according to the teaching of the patents DE 32 19 025 C2 and EP 0 096 236 B2 optionally for storage and promotion of Materials, in particular of different materials used become. It is also possible to use a storage box with its conveyor belt (which can also be called together as a conveyor and silo band) for storing material and the other receiving box with his Conveyor belt (collectively also referred to as conveyor and silo belt) for To use material promotion. The conveyor and silo belts can be used for Parallel feed and simultaneous storage or for parallel removal and simultaneous storage of materials and material fractions be used. For example, gravel and sand can be paralleled to a track construction site.

Fig. 2 shows a side view of a chain of conveying and silo wagons of the type shown in FIG. 1. Waggons 10a, 10b and 10c can be seen, each a lower receiving box 40a or 40b and 40c and an upper receiving box 42a, 42b and 42c, respectively. The Receiving boxes are over a wagon end projecting transfer conveyor 70 and 72 with each other in the sense of a transfer of bulk material from wagon to wagon connected in a conveying direction F, namely the lower receiving box 40a via the transfer conveyor 70a with the lower receiving box 40b and this over the Transfer conveyor 70b with the lower receiving box 40c, and the upper receiving box 42a via the transfer conveyor 42a with the upper Receiving box 42b and the upper receiving box 42b on the Transfer conveyor 72b with the upper receiving box 42c. The transfer conveyor each extend from a lower material transfer level approximately obliquely according to the level of the respective trough floor upwards over the maximum possible filling level of the receiving boxes. The Transfer conveyors can each be on a material input hopper or the like of the connected receiving box rest. The lower receiving boxes are opposite the upper receiving boxes slightly offset relative to the conveying direction F, so that an end region of the respective lower receiving box, possibly a material introduction funnel not up through the respective upper receiving box is covered and so accessible for the supply of material. .

The transfer conveyors are preferably corresponding to relevant track curves laterally swiveling, in order to also in a track curve material of To hand over the waggon to the wagon. Furthermore, the transfer conveyor preferably in a vertical plane at least in a certain Extend to pivot from the Materialeinführtrichtern or receiving tub edges of the leading in the conveying direction F cars to be able to take off. For this purpose, a winch or the like may be provided be.

Fig. 3 shows a corresponding chain of conveying and silo waggons 10a to 10f each with an upper and a lower receiving box. For the respective receiving boxes is the recorded therein or therein conveyed bulk material indicated. The trailing in the conveying direction F shown carriage 10 'is in a forward direction in the conveying direction F as formed the conveyor and silo wagons and has in particular transfer conveyor of the type described. In a conveying direction F rear Area has this wagon material transfer funnels and transfer belts on, via the transfer conveyor a material feed from each other independently in the chain of the upper receiving boxes and in the Enable chain of lower receiving boxes. The wagon 10 'can as Adapter or transfer carriage are called and allows, for example the material supply from bucket of bucket transport wagons or from a conventional conveyor and silo wagon with only a receiving box, for example according to the cited patents DE 32 19 025 C2 and EP 0 096 236 B2 or the proven Type MFS 40 (System Plasser - Knape) or successor types. According to one Here particularly interesting application can into the chains of Receiving boxes are fed to bulk fractions of a rail-classifying and fractionating, possibly in the form of a Sieve or Siebungseinrichtung be provided.

In the chain shown in Fig. 3, the car 10d is currently being emptied, by passing over its transfer conveyor material to the assigned receiving boxes of the leading in the conveying direction F waggons 10e passed becomes. The amount of material stored in the wagon 10e remains constant, since for each receiving boxes each one of the supplied amount of material appropriate amount of material via the transfer conveyor in the Receiving boxes of the car 10f is handed over. The reception boxes These wagons do not store significant amounts of material, as the Emerging material on the wagon across conveying direction F further becomes.

The wagon 10c currently contains no material and does not convey any material from the wagon 10b to the wagon 10d. Wagon 10b is currently over the only serving to promote carriage 10a filled with material, which the adapter wagon 10 'is supplied. Depending on which means of transport or classifying and fractionating the adapter wagon 10 'material or materials are supplied, the receiving boxes of the car 10b simultaneously or sequentially or alternately with Material to be filled, for example, gravel and sand to get out of the Chain of wagons to supply a track construction site.

For example, at a later date, such a situation may arise result that the wagon 10d and the wagon 10e substantially are emptied. These wagons can then be removed from the wagon 10b can be refilled out or it can track the track site immediately from the car 10b over the cars 10c, 10d, 10e and 10f be supplied with materials. One can have a continuous loading and unloading Implement discharge cycle, which is constantly for a sufficient supply of material ensures, so that continuously the required materials of the track construction site can be supplied.

The statements made here apply in a similar way to the removal of different materials from a track construction site. In this case could the adapter wagon 10 ', for example, from a track treatment device with materials, for example two different excavating materials (such as gravel material and substructure material). The conveying direction F can in both cases, ie both for the supply of material as well as for the material removal, the working direction of a track treatment train or a track treatment device (i.e., the direction of travel a migratory track construction site).

Fig. 4 shows an example of a track treatment train as mentioned. 80 denotes a track handling device moving in a working direction A, for example, a so-called tarmac improvement machine, which has a Aushubkette 82. Highlighted material (here For example, gravel and earth construction materials or substructure material together) is conveyed via conveyors 84 to a conventional conveyor and Silo wagon 11 handed over, which serves for material removal and For example, in a working direction A corresponding conveying direction F trailing wagon of a chain of similar transport wagons each with a recording box. The material removal can be done accordingly the teaching of the patents DE 32 19 025 C2 and EP 0 096 236 B2 done.

The track handling device 80 is made of two as a buffer serving conveyance and silo waggons 10a and 10b of the in Figs. 1 to 3 shown type with two different materials or material fractions supplied as needed, via several intermediate cars 90, 92nd away, the elevated conveyor belts 94 and possibly one or more Handover chutes 96, such as for ballast material exhibit. The intermediate wagon 92 has in the embodiment shown a per se known stuffing device. The wagon 90 can be used as a carrier for drive devices, Engines, hydraulic pumps, generators, etc. serve.

The serving as a temporary storage cars 10 a and 10 b are about a trackable screening or screening device that can be identified as a screening cart (as a preferred embodiment of a classifier and fractionator) 200 with the materials needed at the track construction site replenished. The materials become essentially arbitrary Order or in more or less homogeneous mixtures over a feed hopper 202 to the screening carriage 200 and over suitable conveying means, in particular at least one conveyor belt, at least fed to a separating screen of the screening carriage. The in Fig. 4 by a screen drum 204 symbolically represented separation screen separates the supplied materials according to at least one screen characteristic of the separation sieve into two fractions, for example a sand fraction and a ballast fraction, one of which is in the lower chain of receiving boxes and the other in the top chain of receiving boxes the Waggons 10a and 10b via suitable conveying means and transfer conveyors is supplied. Even if currently homogeneous or unmixed Material is input to the feed hopper 202 passes through this material according to the embodiment shown here mandatory the Trennsieb 204. This is in terms of the procurement of the Required materials achieved maximum flexibility without requiring large logistical Effort is required. As part of the cache capacity the conveying and silo waggons 10a and 10b it does not matter in which Order or in which mixing ratios the required individual materials it is sufficient if the brought in Materials related to the buffer capacity of the Waggons 10a and 10b roughly the material consumption ratio at the Track treatment device 80 correspond. Overall, it is achieved that large quantities of different materials supplied to the track construction site can be used to make appropriate construction progress (such as renewed track per hour).

For the procurement of the materials, if necessary in undivided and undivided ones if necessary mixed with each other, conventional conveying and silo wagons 11a, 11b, 11c and 11d are used. Another, in Fig. 5 possibility shown, the two chains connected to each other Receiving boxes for - if necessary - two different Materials or material fractions on the Siebungswagen 200 'means Container wagons 100a, 100b and 100c to supply, respectively a plurality of transport buckets 102 have. To empty the Bucket in a material feed hopper 202 or the like of the screening car 200 'can in a known manner portal cranes 104 be used, at least one of which along the chain of Container transport wagons is movable. The buckets of the wagons can with loaded with different materials, so that by means of a wagon or by means of a chain of coiled cars at the same time various materials are supplied to the track treatment train can. Another possibility is that in a respective bucket several various materials, possibly as a mixture, transported.

If, according to FIG. 4, several conveying and silo wagons are used only one recording box, so these recording boxes each filled with different materials, in which case after emptying for example, the wagon 11c, the example of gravel here has transported, then on the screening cart 200, for example, in passed the lower chain of receiving boxes of the cars 10a and 10b was, subsequently via the car 11 c from the car 11b a other material, such as sand, on the screening car 200 of the supplied to the upper chain of receiving boxes of the cars 10a and 10b becomes. Another possibility is that a single wagon, for example the wagon 11d, transported both gravel and sand has what materials then in the screening cart 200 by screening be separated by means of the separation screen 204 from each other.

Regarding the transfer of materials into the chain of receiving boxes by means of the screening wagon 200 or 200 'according to FIGS. 4 and 5 It should also be pointed out that the screening cart is advantageous with several in the present case with two takeover tapes 70 and 72 to so material simultaneously in the top chain of reception boxes and in the Feed chain of lower receiving boxes.

It has been mentioned above, for example, in the upper chain of Pick boxes crumbly and in the bottom chain of pick-up boxes Sand (PSS material) is fed. Instead, it goes without saying also possible to place the ballast in the top chain of reception boxes and to feed the sand into the lower chain of receiving boxes, anyway then, if preferred, the upper and lower receiving boxes in each case for the inclusion of all in connection with track construction work required materials are suitable.

What related above on the basis of conveyance and silo wagons with two receiving boxes arranged one above the other and one for separation classifying and functionalizing two fractions has been explained, can be easily on conveyor and silo wagons with more than two receiving boxes, for example three receiving boxes, and one designed to separate more than two fractions Extrapolate the classifier and fractionator. It can be done here three or more different materials or material fractions from each other unseparated (if necessary mixed) and according to need over one appropriate classifying and fractionating device, if necessary screening device, feed the track construction site. For example, you can do that think, sand, gravel of a first grain and gravel of a second, undifferentiated from each other by the first grain size if necessary, simultaneously feed the classifying and fractionating device, which then provides appropriate material fractions. Further uses become the expert familiar with track construction work without much thought Imagine immediately. The expert will also recognize immediately that the above on the basis of track construction Explained readily on Construction work in connection with any other line construction site, for example a road construction site, is transferable.

FIG. 6 shows an embodiment variant of the track treatment device 80 with two excavation chains 82a and 82b. The receiving chain 82b decreases For example, the ballast bedding and the receiving chain 82a decreases For example, the gravel substructure (such as earth materials) on. The of the Excavating chains recorded materials are separated Via conveyors 84a and conveyors 84b in a respective associated receiving box 40g and 42g of a conveyor and silo wagon Pass 10g, the one in the direction of or conveying direction A Trailing wagon of a chain of wagons of appropriate design is. The thus a chain of lower receiving boxes supplied gravel and the Unterbauaushub thus supplied to a chain of upper receiving boxes For example, in a continuous loading and unloading cycle be transported away from the track construction site according to FIG. It is also possible for the track treatment device 80 to have a material processing device equip or a separate material processing wagon, for instance between the rail treatment device 80 and the chain of silo and freight cars, provide to the excavation at least one of the conveyor chains for fractions or component materials to separate and / or work up and so on material or materials or to recover material fractions that reused at the track construction site so that, accordingly, less new Material from the feed side (wagons 10 a and 10 b) are supplied got to.

With the two Aushubketten arranged in the track treatment train 82a and 82b as shown in FIG. 6, the entire track ballast and the insufficient viable substructure expanded and working direction of the machine via a conveyor belt system to rail transport vehicles, in Trap of Fig. 6 loaded the two-story conveyor and silo wagons and transported to an external processing plant or disposed of completely become. To save material, transport and disposal costs, It is advantageous if the excavated ballast in a railroad Ballast processing equipment of the track treatment train For example, worked up by screening and Nachgebrechen so far is that he depending on the degree of pollution for reinstallation in the Track is suitable and accordingly as a built-in material to a corresponding section of the track-handling train. For heavily polluted gravel, especially gravel with loamy Dirt, but the problem arises that highly cohesive material remains on the gravel, with clay components both in the Promotion as well as on Sieber orders to clay muds (gravel-like Balls) that can not be screened and thus the work-up of the ballast. The work-up of the ballast is further characterized by firmly adhering to the ballast grains clay and other contaminants questioned. One solution for this is the Integration of a clay-precipitation device and a ballast washing device in the track treatment train. The clay precipitator should serve in particular to the mentioned clay muds to remove the gravel. The washing device is used on the gravel Adhering contaminants, such as adhering clay or adhering fines, to detach from the gravel.

In case of heavy contamination of the ballast with clay, it may However, that is due to a remanufacturing of the gravel Too much time and possibly not sufficient quality results dispensed and the excavated gravel at the recycling plant including the clay eliminator and the washer passes and an external processing or landfill supplies. An external workup is advantageous insofar as that reusable Substances can be separated from polluted gravel and thus (by reducing the volume of the material to be deposited) the landfill costs are lowered.

As explained with reference to FIGS. 4 and 5, one can to ensure a a high workload appropriate material supply materials transported in mixed state. The material supply with for example, two different building materials (such as planum gravel [PSS] and gravel) can be simplified and metabolic problems avoided. The separation of the substances takes place via a between the fabric supply side and the material installation section of the Track treatment train interposed new substance separation module, such as the track-compatible separating sieves 204 and 204 'according to FIGS. 4 and 5.

After separation in the new release separation module but the gravel can still fine particles, especially sandy fine particles, adhere, which may be undesirable, for example because they are in theirs Total quantity of the technical delivery conditions of a client for Gravel contradict. One solution here is the Neustoff separation module downstream washing facility, preferably as a track-mounted Module is executed.

An example of a device according to the invention will now be described with reference to FIGS. 7a and 7b Track treatment train given on the virgin material feed side a material installation section one of a Neustoff separation device having downstream gravel washing arrangement and on the Material removal and reprocessing side of a material excavating section of the track-handling train one of a ballast-processing arrangement downstream clay-precipitator and one of these having downstream ballast washing device.

The track treatment train shown in FIG. 7 has the following carriages, Modules or units: at least one of the removal of substructure materials or bedding residues for disposal or reprocessing serving silo and conveyor wagon A (for example, according to the from DE 32 19 025 C2 and EP 0 096 236 B2 Wagons); if necessary, at least one drive unit (at least a drive carriage) B with hydraulic supply for further modules or units of the track treatment train, in particular the Siebwagens, the excavation chains and the transfer belts, especially the transfer conveyors for overburden to wagon A; a screening cart C with a crusher having a pre-screen (for example double-decker screen) with adjustment device for direct loading (bypass) with excess or Gravel pollution, a crusher for sharpening the ballast, and a secondary screen (for example a monoplane screen) for screening out lower grain having; a track ballast cleaning system (gravel washing module or gravel truck) D with a facility for the removal of Lehmbollen (switchable as required), a high-pressure Intensivbebrausungsreiniger (called here Zyklonreiniger), a high-pressure washing screen, a water treatment plant to reuse the water in the washer or / and for moistening intended for installation PSS material or old ballast; a track-compatible excavation and installation machine E with a digging chain for the old ballast (the track bedding an existing track) and an excavation chain for the track substructure of the track and installation equipment for the reconstruction of the substructure or the ballast track bed made of new material or remanufactured Old material; a material supply and stuffing module F with Transfer conveyors and material chutes and at least one Stuffer; a Trennsieb- and gravel washing module G with at least a separating screen for separating mixed delivered ballast and PSS material and a gravel washing system to wash off at the Gravel grains after separation adhering sandy impurities; and at least one of the material feed of PSS material (planum gravel) and Neuschotter serving conveyor and silo wagons H, for example according to the documents DE 32 19 025 C2 and EP 0 096 236 B2 known wagons, where it due to the sieve of the Module G does not matter whether the material is in separate fractions or as Gravel-gravel mixture is delivered. Here are the separation screen and Washing module G, however, no conveyor and silo wagons accordingly the wagons 10a and 10b shown in FIG. 4 downstream, so that the buffer capacity for already separated materials is relatively small. For this reason, the material should be used as a material mixture be supplied, the mixing ratio of the demand ratio New materials for material installation on module E corresponds.

It should be noted that in the illustration of Fig. 7 is largely is a schematic representation. For example, could the section of module E comprising the old ballast excavating chain 82b in working direction A for easy ballast conveyance in working direction to extend. As will be explained in more detail below, is the old ballast over conveyor belts running in an upper area of the train forward in the working direction, for which the ballast accordingly is to lift vertically. For this purpose, it might be appropriate, the Conveyor belts of the main excavating belt in the joint part between D and E deeper to lay. The transfer belts for the ballast run through the top Joint part between D and E.

The modules, units or wagons A, B, C and D are used for excavation excavation and for recycling of ballast and can be considered together Excavation and recycling plant are addressed. These In principle, the system can be used in conjunction with any layout improvement and ballast cleaning machines are used.

The old ballast and substructure excavating machine E can in principle of be any type, especially with regard to the formation of the excavation equipment (Excavation chains) and the anti-fouling layer and ballast installation device. The substructure excavation chain 82a may preferably also be used for digging gravel, so that the excavation chains 82b and 82b for a particularly large work in parallel can be used if only the gravel to renew or is clean, but the substructure of the track is not renewed.

The stuffing and virgin material transfer module F may be provided with at least one Ballast silo and at least one PSS material silo, where appropriate, the silos by a correspondingly large-sized ballast chute and a suitably sized PSS material hopper can be formed (PSS = surface protection layer).

The following is the material flow for new material and old material explaining how to use the track treatment train as a tarmac train (it becomes the gravel and the substructure of a track renewed) is assumed. From the old ballast excavating chain 82b (as well as if necessary, from the excavation chain 82a under the intermediation of a connection to the crushing conveyor belts 84b producing transfer conveyor) is the Old ballast over ballast conveyor belts 84b-1, 84b-2, 84b-3 in a ballast screen plant 300 (for example, for ballast 24/60) fed, the for example, a two-decker sieve (preferably the finger sieve design) having. Siebrückstände be about conveyor belts 302 and 304 the at least one wagon A (corresponding to the wagon 11 of FIG. 4), together with the removed overburden (especially under-floor material), as will be explained. At the end of the conveyor belt 84b-3 a bypass conveyor arrangement is provided, which allows the old ballast not the screen 300, but on the conveyor belts 304 the Overburden and thus to the wagon A supply, if the reprocessing of the ballast due to excessive contamination or damage not useful or not possible.

The excavated subgrade material is transferred from the excavation chain 82a Conveyor belts 84a-1, 84a-2, 84a-3, 84a-4 leading to the wagon A. Abraum conveyor belts 304 supplied.

From the screening plant 300, a conveyor belt 306 leads to a ballast crushing plant 308. The crushed ballast is transported via a conveyor belt 310 a Nachsiebungs plant 312 supplied (for example, for ballast 24/60), in the subgrains, in particular by the breaking in the Crusher 308 resulting subgrits are screened out. The sieve residues (Unterkörnungen or Nachsiebrückstände) via conveyor belts 314, optionally comprising the conveyor belts 302, the overburden conveyor belts 304 and thus the tailing wagon A supplied.

The corresponding one target grain, that of the screen 312 (For example, designed as a monoplane sieve) not sieved gravel is conveyed via conveyor belts 316 of a clay ball precipitator 320, which is also referred to as clay toners. The clay toner has at least one spiked roller with one or more (For example, two) associated rubber rollers or foam rubber rollers interacts and Lehmbollen excreted from the gravel, and Although clay mud, which corresponds to the desired grain of the ballast Have size and thus not eliminated by sieving can. The clay bolls are spiked by the spiked spines, removed from the gravel and then stripped from the spiked roller. It may be provided a bypass, which allows the gravel on Lehmtoner pass, for example if the gravel is not or only slightly is lame.

The liberated from the clay soil gravel is a so-called cyclone scrubber 322 supplied, in which the ballast in a fall distance from below intensive with rotating high-pressure water jets is brewed to to remove heavy dirt. By turbulence becomes coarse dirt effectively released from the gravel grains. The gravel falls For example, on a rotating, high-pressure nozzles having disc, and is then centrifugally thrown radially outward. It can a bypass is provided, which allows the ballast at the cyclone scrubber pass by if the ballast is less heavily polluted. The arrangement may be such that the clay toner 320 and the Cyclone scrubber 322 jointly bypassing is provided.

The ballast, if necessary after passing through the clay toner 320 or / and the cyclone washer 322, is then placed on a high pressure wash screen 326, on the gravel with shaking or oscillating movements of the washing screen promoted and intensified with water from below and above.

In the area of the high-pressure washing screen 326 are in the module D also a Wash water settling tank with a drainage channel and (at 330) a water tank and a washing water treatment plant provided. The water treatment is preferably as follows: that of the cyclone scrubber 322 or discharged from the high-pressure washing screen 326 wastewater placed in the wash water settling tank so that solid components, especially mud, can settle. In an upper level area of the washing water contained in the settling tank water is removed and the water tank and / or the washing water treatment fed. Via a drainage channel integrated into the settling tank sludge is fed to a sludge centrifuge 324 to remove the sludge to excrete from the water. The liberated from the mud water is from the sludge centrifuge to the water tank and / or the washing water treatment fed. Preferably, a private fresh water tank and a private hot water tank provided. From the service water tank or / and directly from the washing water treatment can be lines into the area of the ballast excavating chain 82b or the substructure excavating chain 82a be guided to avoid the formation of dust To be able to irrigate old gravel before digging. Furthermore, lines can in the area of the tarmac layer module E module be guided in order to be able to moisten PSS material for installation.

The remanufactured and in module D at least one washing or Old gravel undergone washing-up treatment, hereinafter also recycled gravel called conveyor belts 332-1, 332-2, 332-3, 332-4 and 332-5 fed to a ballast hopper 334, the same time serves as a ballast silo. The ballast installation device of the built-in component of the module E derives from this funnel, if necessary, both recycled gravel as well as Neuschotter.

The supply of new material takes place in the following way. The end the at least one wagon H (corresponds to the wagon 11d of FIG. 4) deducted material, usually a mix of new and Planumskies (PSS material) is via a transfer conveyor 340 in a Sieve 204 "(for example, for ballast 24/60) given, for example executed with at least one finger sieve. That by the Screener as Siebrückstand passing PSS material is about Conveyor belts 342-1, 342-2 and 342-3 into a PSS material hopper 344 given that also possibly fulfills silo function. The Protective layer installation device of module E obtains as required PSS material from this funnel.

The gravel sieved by the screen 204 "from the PSS material becomes via a conveyor belt 346 in a ballast washing plant 350 of the module G. supplied, for example, a high-pressure washing wire according to the Washer 326 has. The module G is further provided with at least one Water tank, a wash water settling tank, a drainage channel, a sludge centrifuge and a washing water treatment carried out. An intensive prewashing by means of a cyclone washer or the like is not required for the new gravel material usually be. The module can with regard to the ballast and this associated additional facilities but as the module D to be executed.

The washed gravel is conveyed by conveyor belts 352-1 and 352-2 Ballast hopper 334 supplied.

You can also have your own ballast hopper for recycling gravel and provide a separate funnel for the new ballot, For example, if you have recycled gravel and newts in one would like to install a certain mixing ratio.

One would like to have the through two gravel washing facilities, namely a recycling gravel car wash and a Neuschotter car wash Avoid investment and maintenance costs, so you can the track treatment train even with a single gravel washing system. This gravel washing plant is then by appropriate conveyor belts both the remanufactured, possibly freed from clay soil old gravel as well as the new ballast. For this it would be particularly appropriate the gravel washing plant in the module E, preferably in the area of or the ballast chute, to integrate. Would like to be with one conventional excavating and mounting machine E, so could For example, think about it, about a modified conveyor belt arrangement The Neuschotter first in working direction forward over the Module E to the washing device 322, 326 of the module D to supply, where he washed together with the reclaimed old gravel or is washed off. With appropriate silos you can make sure that the washing device old gravel and Neuschotter in a certain Mixing ratio is supplied.

Regarding the washer 350 should be mentioned that one may also provide a bypass to bypass the car wash, so that in the case of a delivery of sorted, not with PSS material mixed gravel may be waived on a washing treatment can. Concerning the costs incurred in the washers 350 and 322, 326 Sludge can be provided that this supplied to the PSS virgin material is to be installed with this. The washing water treatment can be avoided or the effort for the washing water treatment can at least be kept small when used Washing water for moistening the substructure material or used for moistening the excavated or excavated ballast. In the track treatment train entrained fresh water is then primarily for the washing of the ballast, but not for moistening the substructure material or the ballast used.
