EP1249536A2 - Method for supplying a building site with building materials - Google Patents

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 different types, at the construction site at the same time or / and bulk goods required one after the other. For example, it will be on the supply of track construction sites with track building materials, for example with gravel material, on the one hand, and PSS material (for example in the form of a mixture of round grain material and sand), on the other, thought. For those required at the construction site to be made available according to the procedure Bulk goods can be homogeneous, uniform or mixed Bulk goods from uniform or different components act. The respective bulk material can therefore consist of different ones Bulk materials must be mixed together (e.g. sand and round grain or gravel of different grain 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 one another Transported to the construction site, creating a great logistical effort if different materials in a certain ratio to each other are needed. The following example shows this:

When planning improvements in track construction, ballast and PSS material in particular have to be transported to the track construction site as new materials, unless old material can be reused on site through material recycling. If, according to an ambitious goal, you want to achieve an hourly output of 100 meters of track, you need, for example, 250 m ^{3 of} ballast and 450 m ^{3 of} PSS material per hour of new materials. With a shift duration of, for example, 12 hours, around 8,400 m ^{3 of} new materials are required, which have to be transported over the work track to the track construction site (construction supervisor), since an existing service track is still required for rail traffic. Feeding such quantities of material to the track construction site in the required material ratios is a difficult logistical problem and, if at all, only possible using a very difficult and personnel-intensive logistical chain with a high capital expenditure for the provision of special transport and silo wagons, especially possibly on the basis of rail-accessible ones Conveyor and silo wagons, which in the German patent application filed on April 12, 2001 by the applicant GSG Knape Gleissanierung GmbH "Rail-accessible conveyor and silo wagon, transport train and method for receiving, temporarily storing and delivering materials in connection with track construction work", official file number 101 18 393.3. These conveyor and silo wagons enable the simultaneous, separate feeding and procurement of at least two different materials or material fractions to a track construction site.

Based on conventional conveyor and silo wagons and conventional ones Transport and conveyor logistics, for example according to the teachings of Patents DE 32 19 025 C2 and EP 0 096 236 B2, but it appears excluded to achieve a targeted hourly performance as mentioned. In particular, it is based on conventional filling of material silos based on the material creating Bucket wagons and gantry cranes for transferring the material from the Buckets on conveyor belts or in the silos, may not be possible, essential to supply more material to the construction site than for a meter output of about 30 meters per hour is needed. An increase in the number of used Portal cranes can then due to the higher number of maneuvers bring no significant increase in performance. An enlargement the filling capacity of the buckets (enlargement of the buckets) is with regard to the Axle loads on the drive-over bridges between the bucket cars are 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 goods are transported or supplied to the construction site independently of one another and to a certain extent “sorted by type,” even if this results in additional effort for separating materials at the construction site. The invention proposes for the method mentioned at the outset that it comprises at least the following steps:

• Loading, one after the other or simultaneously, the respective bulk quantities of a plurality of different types of bulk goods,
• Transporting, in succession or simultaneously, the loaded bulk quantities to the construction site or to a location adjacent to it,
• Classify and - in accordance with the classification - fractionate the bulk material quantities transported according to at least one bulk material property, possibly grain sizes or grain size ranges,
• Provide and, if necessary, temporarily store the bulk material fractions corresponding to the classification in association with the construction site.

Within the scope of the invention, the various bulk materials are in the state to load in principle any mixing or non-mixing and transport it so that it is comparatively low in logistics Effort is possible, large quantities of different materials to be loaded and transported to the construction site. The on the Construction site at the same time and / or successively bulk goods then only on the basis of the classification and, if necessary, fractionation of the Bulk quantities transported forwarded in assignment to the construction site and cached if necessary.

The invention is based on the consideration that the ratio of new substances to be installed is often known and then often at least for certain sections remain the same. This makes it possible, for example, from Plant or a loading point the required, regularly homogeneous New materials (e.g. crushed stone and PSS) in the desired ratio loading, possibly in a mixed state or simply by entering of bulk quantities of the bulk goods concerned one after the other Container or means of transport (for example a number of wheel loader bucket loads of a first bulk material and a number of wheel loader bucket loads of a second bulk material). The in the container or Materials contained in the means of transport can then be taken to the construction site or this neighboring location are transported or promoted and the Bulk goods are then classified and installed at the construction site fractionated, i.e. separated again, for example by sieving.

In connection with a track construction site can be transported to and feeding the materials advantageously from the patents DE 32 19 025 C2 and EP 0 096 236 B2 well-known conveyor and silo wagons can be used, and it can be particularly advantageous a funding and Transport logistics implemented according to the teaching of these patent specifications become. So after emptying, those further away from the track construction site Conveyor and silo wagons are pulled over the construction track and refilled become. In the meantime, they will be 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 by the meanwhile emptied, remaining in the transport train Conveyor and silo wagons conveyed through and from that of the track construction site next conveyor and silo wagon not yet completely emptied pent 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 transportation and conveyor logistics on several different, more or less strongly mixed building materials apply since one has so far for obvious reasons it is assumed that it makes no sense to have different materials from each other to be transported and fed separately, since this is because mandatory separation of the materials after feeding requires corresponding mechanical effort and thus cost.

Further considerations have led to the realization that it is in practice it is not at all necessary to mix the various bulk goods with one relative demand at the construction site to convey exactly the right ratio and deliver it to the construction site. So after the separation the materials, for example through a sieving device handed over to respective silos, for example by means of transfer belts be and temporarily stored there, so that the construction site as needed can be supplied with the required materials, too if the required materials are not in a supplied subset Target ratio is present or a subset even of the bulk material a variety is formed. In particular, the silos mentioned in the German patent application filed on April 12, 2001 Conveyor and silo wagons with at least two transport boxes are advantageous can be used, optionally a separate one Temporary storage of the bulk fractions or the required bulk goods and promoting them towards the track construction site, in particular to a built-in device. Through this temporary storage option could, for example, be one used for procurement conventional conveyor and silo wagons according to the patent specifications DE 32 19 025 C2 and EP 0 096 236 B2 partly, approximately half, with one material and the other part, about the other half, with one other material, for example half filled with PSS material and the other half with gravel material. For example such a conveyor and silo wagon completely with gravel material and one or more other such conveyor and silo wagons each be completely filled with PSS material. The materials in question are then according to the teaching of these patents along the Chain of conveyor and silo wagons conveyed towards the track construction site and performed on a separation plant, in particular a screening plant to provide the individual materials. Material supply problems at the Installation location can be due to the intermediate storage of the bulk fractions do not arise.

So it is possible to mix precisely, inexactly mixed, homogeneously mixed, non-homogeneously mixed and unmixed quantities of material, for example by means of the conventional conveyor and silo wagons mentioned to bring in as a feeder, because the classification and - so far required - fractionation (separation, especially screening) for the Provision of the required bulk fractions, where appropriate for a separate homogenization of the bulk fractions can.

Excess new materials that are not currently required at the construction site can in the mentioned silos or conveyor and silo wagons after the German patent application dated April 12, 2001. However, it is extremely useful if the total brought in Materials the required ratio (installation ratio) of the required Bulk goods at the construction site at least roughly correspond to one comparatively small buffer capacity and no Having to remove new material from the construction site unused. A however, as stated, exact premixing of the material is not necessary, which is also very advantageous in that materials from different factories, loading points or manufacturers Need to become.

In the above explanations, it was assumed that at least one, preferably all, of the bulk material fractions provided corresponds directly to a respective bulk material required at the construction site or correspond. However, this is not mandatory. One can also provide that at least two of the bulk solids fractions provided can be mixed together to create a respective one required at the construction site Provide bulk goods and, if necessary, store them temporarily. The one at the construction site bulk materials required simultaneously or / and one after the other So after this training proposal only from the provided Bulk material fractions produced, namely mixed together. Then it can to a certain extent a manufacturing step is shifted to the construction site, the traditionally takes place in the manufacturing plant of a building material manufacturer. As far as the required bulk goods are only produced close to the construction site (mixed together) the possibility opens up that no more Bulk quantities are loaded and transported to, as such at the construction site can be used for installation, but that in the case of Building materials mixed from different bulk materials are the original bulk goods, such as sand and round grain in Case of PSS material, loaded and transported according to the invention proposal become and that after providing appropriate Bulk material fractions after the classification and fractionation the required Mix material (PSS material in the example) according to the training proposal first made, namely mixed together and - so far required - is homogenized.

In this context, one will worry about the composition of the various materials required at the construction site. So it may be appropriate to avoid a large one Classification and fractionation effort of conventional recipes to deviate in order to provide one or more bulk material fractions Mixing different bulk materials, for example to use gravel on the one hand and PSS material on the other. So could you remember for the PSS material instead of the usual round grain to use small-grained gravel material from a corresponding gravel fraction.

It is proposed that the bulk quantities transported in a classifier and fractionator can be entered based on at least one property, possibly grain sizes or grain size ranges, of the entered bulk goods and the bulk goods entered classified by the at least one property and - if necessary - fractionated and bulk solids according to the classification emits. It is particularly remembered that the classification and Fractionation device comprises at least one sieve arrangement, which according to subjecting bulk material to at least one sieving characteristic to at least one sieving and - depending on the composition of the bulk material with regard to the Sieving characteristic - the bulk material in at least one, at least regularly transferred two bulk fractions.

As was already clear from the explanations above, it is within the scope of the Invention that the bulk goods transported regardless of the Classified composition of a respective subset, in particular undergo at least one screening.

It has already been indicated that the bulk quantities are at least partially can be loaded as a mixture of the bulk goods concerned. Furthermore, it has already been indicated that the bulk quantities are at least rough load according to at least one requirement ratio and mixed if necessary can be, the demand ratio indicates in which Ratio of bulk goods needed at the construction site.

The invention has already been described above in relation to track construction work explained. A corresponding track construction site can be viewed as a line construction site that progress along a line, namely the track. The Bulk quantities can then according to the invention along the line, namely track-bound via the track affected by the track construction site, the Track construction site are fed. In general, it is proposed that the construction site is a line construction site progressing along a line and that the bulk quantities or the required bulk goods along be fed to the line of the construction site. For example, it will 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 over the road affected by the road construction site be fed.

There are great advantages if the road is multi-lane and the Road construction site at least currently only one lane of several lanes the road concerns. It is proposed that the bulk quantities or the bulk materials required by the road construction site via this the lane affected by the road construction site, so that the others Traces of traffic can remain free. For example, the Road have two lanes and two lanes, of which only one one is affected by construction while the other is for normal Traffic without hindrance through material supply for the construction site can continue to be used.

The invention further relates to a rail or street Classifying and fractionating device, which has one input area and several Output areas and which has at least one property if necessary grain sizes or grain size ranges, one in the input area entered bulk goods and the bulk goods entered after which classifies at least one property and - according to the Classification - fractionated to give bulk fractions corresponding to the classification to be delivered to the delivery areas.

It is further proposed that the classifying and fractionating device comprises at least one sieve arrangement designed for this is, according to at least one sieve characteristic, bulk material at least one Undergo screening 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 fractions.

The invention further relates to a transport chain for bulk material, comprising at least one classifying and fractionating device such as indicated above and at least one street-going or rail-accessible conveyor and silo wagons (conveyor and silo wagons, if applicable) for conveying and storing bulk goods. It will be sent to one in particular such a wagon or wagon, which has at least one of its own (possibly own car) has a recording box for storage of bulk material is suitable and in a floor area a wagon Has (possibly wagon-specific) material conveyor, with at least a bulk goods reception area from one end of the wagon (end of wagon if necessary) forth bulk goods can be entered in the receiving box Bulk material entered by means of the material conveyor along the conveyor and silo wagon towards the other end of the wagon is transportable and via at least one transfer device Bulk goods can be discharged from the receiving box at the other end of the wagon, possibly in an assigned bulk goods receiving area of an assigned other conveyor and silo wagons of the corresponding type. It will in the event of track construction work especially thought of one, preferably several of the patents DE 32 19 025 C2 and EP 0 096 236 B2 use known conveyor and silo wagons.

The transport chain can at least be a street or rail street Material dispensing device for dispensing on a street and Track construction site required at the same time and / or in succession of bulk goods have, directly or indirectly on the classifying and fractionation connected. Furthermore, the transport chain can be a construction or Treatment facility for machine-assisted road or track construction or for machine-assisted street or track treatment, the material delivery device of the construction or treatment device assigned by material feed.

The material delivery device can have at least one road-going one or rail-type bulk material storage device or / and at least a street-type or rail-type bulk material mixing device the classification and fractionation device. It's going on referenced above.

At least one street-going storage device can advantageously be used as the bulk material storage device or rail-accessible conveyor and silo wagons (conveyor and Silo wagon) for conveying and storing bulk goods, which has several wagon-specific (possibly wagon-specific) receiving boxes, which are each suitable for storing bulk goods and in one Have a respective wagon's own material conveyor, with at least one respective bulk goods receiving area Bulk goods in the respective receiving box from one end of the wagon can be entered, bulk material entered in the respective receiving box by means of the respective material conveyor along the conveyor and Silo wagon can be transported towards the other end of the wagon and via at least one respective transfer device bulk material on the other The end of the carriage can be dispensed from the receptacle, if necessary into one assigned bulk receiving area of an assigned further Conveyor and silo wagons of the appropriate type. It will in the case of track construction work especially thought of conveying and silo wagons of the in the applicant's German patent application dated April 12, 2001 Kind of use.

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

The transport chain according to the invention (possibly the transport train or track handling train) can be advantageous in the context of the inventive method used to supply a construction site with building materials become. For that carried out using the transport chain In a further development method, it is proposed in particular that at least one material transport wagon (possibly material transport wagon) is used simultaneously or in succession and in the case of a larger or permanent material requirements also repeated at least two different building materials or building material fractions (hereinafter only called building materials) separated or unseparated, optionally mixed together, to a terminal Conveyor and silo wagons (possibly conveyor and silo wagons) with at least to bring up a receiving box of the chain, and that the Building materials or the transported mixture material then in the or a receiving box of this conveyor and silo wagon from one end of the wagon is handed over and in the chain longitudinal direction transported over at least one such conveyor and silo wagon will towards the construction site, the building materials or the Mixing material along a respective carriage through the material conveyor of the receiving box towards the other end of the carriage is promoted and, if necessary, from this end then by the transfer device of the receiving box in the reception area of an assigned Receiving box of an immediately adjacent further such Conveyor and silo wagons are handed over, and taking the building materials or the mixture material in at least one such conveyor and Silo wagon is cached and according to the need the building materials towards the construction site and finally the classification and fractionation device is supplied. In the case of several successive conveyor and silo wagons (possibly conveyor and silo wagons) it is each with at least one conveyor and receiving box advantageous if for the temporary storage of the building materials or Mix material first a wagon closer to the construction site (possibly wagon) is filled.

In a further development it is proposed that the Building materials or the mixture material along the straight conveyor and silo wagons to be filled using the conveyor the receiving box is conveyed more slowly than on at least one previous or / and as - after delivery from the reception box to Onward transport towards the construction site - on at least one subsequent one Conveyor and silo wagons.

The material transport wagon (possibly material transport wagon) can, for example a container transport wagon (possibly container transport wagon) with at least one a material transport bucket or a similar conveyor and silo wagon (possibly conveyor and silo wagon) with at least one conveyor having receiving box. Regarding the funding and Silo wagons are particularly thought of wagons in the Patent specifications DE 32 19 025 C2 and EP 0 096 236 B2 described To use species. But you can also have wagons with several Transport boxes according to the teaching of those submitted on April 12, 2001 Use the applicant's patent application, in which case the various Bulk quantities are not separated from one another and, if necessary, mixed into the receiving boxes loaded and possibly transported along the receptacle boxes become. The possibility given to these wagons is different Separate materials from each other and sort of by means of The simultaneous conveyance and transport of a wagon is then concerned loading and transporting not used. This functionality of the new conveyor and silo wagons after the However, as already explained above, the above-mentioned application from April 12, 2001 can advantageous after the classification and fractionation of the materials can be used for temporary storage.

For the method it is proposed in particular that the Classification and fractionation device provided bulk fractions or / and bulk materials mixed together therefrom separately in a respective assigned receiving box one or more Conveyor and silo wagons with receptacle boxes (conveyor and Transfer silo wagons) from one end of the wagon (possibly wagon end) and in the longitudinal direction of the chain (possibly longitudinal direction of the train) transported at least one such conveyor and silo wagon are towards the construction site, with the fractions or materials along a respective wagon (possibly wagons) through the material conveyor of a respective receiving box towards the other Wagon end (possibly wagon end) are promoted and if necessary by this Then end by the transfer device of the relevant receiving box in the reception area of an assigned receiving box immediately adjacent other such conveyor and silo wagons (possibly wagons) are passed, and the fractions or materials in at least one of the conveyor and silo wagons with several Recording boxes are cached and according to the Need for the respective fraction or material in the direction be transported to the construction site.

As a rule, it will be useful that in the case of several on top of each other The following conveyor and silo wagons (possibly wagons) each with several Storage boxes for the temporary storage of the fractions or materials first a car closer to the construction site is filled. It is also proposed that for the temporary storage of a fraction or a material this along the conveyor and silo wagons to be filled by means of the conveyor of the fraction or the material receiving Admission box is promoted more slowly than at least a previous one 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 those mentioned several times above, submitted on April 12, 2001 Registration 101 18 393.3 of the applicant GSG Knape track renovation GmbH with the title "Rail-accessible conveyor and silo wagon, transport train and recording, caching, and delivery methods of materials related to track construction work "or one European subsequent application for this is by reference in the Disclosure of the present application included.

It should be noted that within the framework of the The inventive method 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 undergoing a washing or washing-up treatment, and then provided in association with the construction site (possibly line construction site) becomes. For this purpose, the classification and Fractionator with a corresponding washing arrangement be executed. Another option is to have a separate track or to use street-going washing facilities, which may be the Transport chain according to the invention (possibly transport train or Track treatment train) is associated. It will refer to the on June 12, 2001 German filing with the German Patent and Trademark Office Patent application No. 101 28 480.2 with the title "Process for Material washing and / or clay excretion Bulk material in connection with construction work on a Line construction site and corresponding rail or street Annex "or a European subsequent application, the Disclosure by reference fully into the disclosure of the present application is included.

1 shows a railway wagon designed as a conveyor and silo wagon 10, a given in terms of its cross-sectional dimensions Limit profile 12 is sufficient. The wagon 10 has a vehicle frame 14 Wagon side walls 16 on. The wagon frame 14 is in itself known manner on a plurality of bogies 18 each stored with several wheel axles.

In a lower wagon area 20 there are low-floor units Various drive devices for those to be described below Material conveyor, storage and handover facilities arranged.

A material receiving trough 24 is located above the lower wagon area held stationary in the vehicle frame 14, which has a floor 26 and side walls 28 and together with one of the side walls 28 section 30 of the side walls 16 adjoining the top has a receiving box forms for bulk material. A bulk level is an example indicated by the dashed line 32.

The bottom 26 of the receptacle has in a manner known per se and Way an upper run of an endless conveyor belt, for example a scale belt, by means of which the received in the receiving box 40 Material can be conveyed in the longitudinal direction of the wagon.

Above the receiving box 40, which is also referred to below as the “lower receiving box” is called, is another ("upper") recording box 42 arranged, which also has a receiving trough 44 with a bottom 46 and side walls 48. The upper receiving box 42 can also Pick up bulk material; a corresponding level is through dashed line 50 indicated as an example.

The bottom 46 of the upper receiving trough 44 points in a corresponding manner Way an upper run of a conveyor belt, for example a scale belt, on that for conveying the bulk goods in the longitudinal direction of the wagon serves.

The upper receptacle 44 is not stationary in the vehicle frame 14 arranged, but by an adjustment mechanism, not shown Hydraulic base adjustable in height. If you lower the upper receptacle 44 decreases so that it increases above the tub floor 46 for material storage available space with a corresponding reduction in the above the tray floor 26 of the lower receiving tray 24 for material storage available space and vice versa. By adjusting the height The upper storage trough can therefore be the material storage capacity of the upper and lower receiving boxes 40 and 42 can be adjusted in opposite directions to each other, which becomes a capacity increases and the other capacity is reduced.

It is assumed that in Fig. 1 regarding the upper receiving trough 44 whose uppermost position is shown in the vehicle frame 14. If you lower the receiving trough 44, bulk goods can go above the level of the upper edges of the tub side walls 48, because to the side of the side walls 48 wagon-stationary boundary walls 52 are provided, which are lower than in FIG. 1 adjustment positions the upper receptacle 44, the side walls 48 of the top so to speak extend and together with the tub sides 48 the receiving box 42 limit laterally.

The upper receptacle 44 together with a support for the tub Intermediate frame 54 adjusted in height. The lowest adjustment position of the upper receptacle 44 is through the upper edges of the side walls 28 of the lower trough 24 determined. The lower receiving box 40 is then essentially only laterally through the side walls 28 limited because 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 Significant extent no longer possible in the upper receptacle is.

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

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

The receiving boxes and their conveyor belts can each be different from each other independently according to the teaching of the patent specifications DE 32 19 025 C2 and EP 0 096 236 B2 optionally for storing and conveying Materials, especially of different materials, are used become. It is also possible to use the one receiving box with its conveyor belt (which can also be designated together as a conveyor and silo belt) for material storage and the other storage box with his Conveyor belt (collectively also known as conveyor and silo belt) for Use material handling. The conveyor and silo belts can be used for parallel supply and simultaneous storage or parallel removal and simultaneous storage of materials and material fractions be used. For example, gravel and sand can be laid in parallel lead to a track construction site.

Fig. 2 shows a side view of a chain of conveyor and silo wagons of the type shown in FIG. 1. Wagons 10a, 10b and 10c can be seen, each a lower receiving box 40a or 40b or 40c and have an upper receiving box 42a or 42b and 42c. The Receiving boxes are transfer conveyors cantilevered over a wagon end 70 and 72 with each other in the sense of a transfer of bulk material connected from wagon to wagon in a conveying direction F, namely the lower receiving box 40a over 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 one Receiving box 42b and the upper receiving box 42b over the Transfer conveyor 72b with the upper receiving box 42c. The transfer conveyor each extend from a lower material transfer level approximately at an angle according to the level of the respective tub floor upwards over the maximum possible fill level of the receiving boxes. The Transfer conveyors can each be on a material feed hopper or the like of the connected receiving box. The lower receptacle boxes are opposite the upper receptacle boxes slightly offset against the conveying direction F, so that an end region of the respective lower receiving box, which may be a material introduction funnel has, upwards not through the respective upper receiving box is covered and is thus accessible for the material supply.

The transfer conveyors are preferably in accordance with relevant track curve radii laterally swiveling, in order to be able to track material even in a track curve To be able to hand over wagons to wagons. Furthermore, the transfer conveyors preferably in a vertical plane at least to a certain extent Extendable to the extent of the material introduction funnels or receptacle edges of the wagon leading in the direction of conveyance F. to be able to take off. A winch or the like can be provided for this purpose his.

Fig. 3 shows a corresponding chain of conveyor and silo wagons 10a to 10f each with an upper and a lower receiving box. For the respective receiving box is the one received therein conveyed bulk material indicated. The trailing in the direction of conveyance F. shown wagon 10 'is in a front area in the conveying direction F as trained the conveyor and silo wagons and in particular has transfer conveyors of the type described. In a conveying direction F rear In this area, this wagon has material transfer hoppers and transfer conveyor belts on the material feed from each other via the transfer conveyor independently in the chain of the upper receiving boxes and in the Allow chain of lower storage boxes. The wagon 10 'can be Adapter or transfer wagons 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 in accordance with the aforementioned patents DE 32 19 025 C2 and EP 0 096 236 B2 or from the proven Type MFS 40 (System Plasser - Knape) or successor types. According to one here particularly interesting application can be in the chains of Receiving boxes bulk material fractions are fed by a rail-accessible classification and fractionation device, possibly in the form of a Screening or screening device can be provided.

In the chain shown in FIG. 3, the wagon 10d is currently being emptied, by delivering material to the associated receiving boxes via its transfer conveyor of the wagon 10e leading in the conveying direction F is handed over becomes. The amount of material stored in the wagon 10e remains constant, since one of the supplied amount of material for each of the two receiving boxes appropriate amount of material on the transfer conveyor in the Receiving boxes of the wagon 10f is handed over. The recording boxes of this wagon do not store any significant quantities of material, since that emerging material is conveyed across the wagon in the direction of conveyance F. becomes.

The wagon 10c currently contains no material and also does not convey any material from wagon 10b to wagon 10d. Waggon 10b is currently over the wagon 10a, which is only used for conveyance, is filled with material which is supplied to the adapter wagon 10 '. Depending on which means of transport or classification and fractionation means the adapter wagon 10 'material or materials can be supplied, the receiving boxes of the wagon 10b simultaneously or in succession or alternately with Material to be filled, for example crushed stone and sand, from which Chain of wagons to be able to supply a track construction site.

Such a situation may arise at a later date result that the wagon 10d and the wagon 10e essentially are emptied. These wagons can then be from wagon 10b can be filled out again or the track construction site can immediately out of the wagon 10b over the wagons 10c, 10d, 10e and 10f be supplied with materials. One can continuously load and Implement unloading cycle that is constantly sufficient for a sufficient material ensures that continuously the required materials of the track construction site can be supplied.

What has been said here applies here correspondingly to the removal of different materials from a track construction site. In this case it could the adapter wagon 10 ', for example from a track treatment facility forth with materials, for example two different excavation materials (such as ballast and substructure material). The conveying direction F can in both cases, that is, both for the material supply as well as for material removal, the working direction of a track treatment train or a track treatment facility (i.e. the direction of travel a walking track construction site).

Fig. 4 shows an example of a track treatment train as mentioned. 80 denotes a track treatment device moving in a working direction A, for example a so-called formation improvement machine, which has an excavation chain 82. Excavated material (here e.g. gravel and earth building materials or sub-construction material together) is connected to a conventional conveyor and conveyor 84 Hand silo wagon 11, which is used for material removal and for example the conveying direction corresponding to the working direction A. F trailing wagons of a chain of similar conveyor wagons each with a receiving box. The material removal can accordingly the teaching of the patent specifications DE 32 19 025 C2 and EP 0 096 236 B2 done.

The track treatment device 80 is made up of two as intermediate stores serving conveyor and silo wagons 10a and 10b of the in FIGS. 1 to 3 shown type with two different materials or material fractions supplied as needed, namely via several intermediate wagons 90, 92 away, the elevated conveyor belts 94 and possibly one or more Have transfer chutes 96, for example for crushed stone material. The intermediate wagon 92 has one per se in the exemplary embodiment shown known stuffing device. The wagon 90 can be used as a carrier for drive devices, Motors, hydraulic pumps, generators, etc. are used.

The wagons 10a and 10b serving as temporary storage are over a trackable sieve or sieve device which can be designated as a sieve wagon (as a preferred embodiment of a classification and fractionation device) 200 with the materials required at the track construction site replenished. The materials are essentially arbitrary Order or in more or less highly homogeneous mixtures a feed hopper 202 fed to the screening trolley 200 and over suitable funding, in particular at least one conveyor belt, at least a separating sieve of the screening car. That in Fig. 4 by a sieve drum 204 symbolically represented represents a separating sieve separates the supplied materials according to at least one characteristic curve the separating screen in two fractions, for example a sand fraction and a crushed stone fraction, one of which is in the lower chain of storage boxes and the other in the top chain of storage boxes of the Wagons 10a and 10b via suitable conveyors and transfer conveyors is fed. Even if currently homogeneous or unmixed Material is fed to the feed hopper 202 this material is mandatory according to the embodiment shown here the separating sieve 204. As a result, the required materials achieved the greatest flexibility without being logistic Effort is required. As part of the cache capacity of the conveyor and silo wagons 10a and 10b, it doesn't matter which one Order or in what mixing ratios the individual materials required be transported, it is sufficient if the brought in Materials related to the cache capacity of the Wagons 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 are fed to the track construction site to be able to make appropriate construction progress (such as renewed track per hour).

To procure the materials, if necessary in separate and if necessary, mixed together, conventional conveyor and silo wagons 11a, 11b, 11c and 11d can be used. Another, in Fig. 5 shown possibility is to connect the two chains from each other Storage boxes for - if necessary - two different ones Materials or material fractions via the screening trolley 200 ' To supply container transport wagons 100a, 100b and 100c, each have a plurality of transport buckets 102. To empty the Buckets into a material feed hopper 202 or the like of the screening wagon 200 'can gantry cranes 104 in a manner known per se are used, at least one along the chain of Container transport wagons is movable. The buckets of the wagons can also be used be loaded with different materials, so that by means of a wagon or by means of a chain of wagons attached to each other at the same time different materials are fed to the track treatment train can. Another possibility is that there are several in each bucket different materials, possibly as a mixture, are transported here.

4, several conveying and silo wagons are used only one receiving box at a time, so these receiving boxes each filled with different materials, then after emptying for example the wagon 11c, which for example brings up gravel has transported, which then, for example, in the screening trolley 200 hand over the lower chain of receiving boxes of wagons 10a and 10b was subsequently entered via wagon 11c from wagon 11b other material, such as sand, over the screening trolley 200 upper chain of receiving boxes of the wagons 10a and 10b fed becomes. Another possibility is that a single wagon, for example the wagon 11d, transported both gravel and sand which materials are then screened in the screening car 200 be separated from one another by means of the separating screen 204.

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 to point out that the screening car is advantageous with several, here with two transfer belts 70 and 72 so material simultaneously in the upper chain of receiving boxes and in the To be able to feed the chain from the lower receptacle boxes.

It was mentioned above that, for example, in the upper chain of Gravel storage boxes and in the lower chain of storage boxes Sand (PSS material) is fed. Instead, it goes without saying also possible to put the ballast in the upper chain of storage boxes and at least feed the sand into the lower chain of receptacle boxes then when - this is preferred - the upper and lower receiving boxes each for the inclusion of all in connection with track construction work required materials are suitable.

The above in connection with conveyor and silo wagons with two stacking boxes and one for separation classification and functioning device designed by two fractions was 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 classification and fractionation device. It can be done three or more different materials or material fractions from each other undivided (mixed if necessary) and according to requirements via a appropriate classification and fractionation device, if necessary screening device, lead to the track construction site. You can do it, for example think sand, crushed stone of a first grain and crushed stone of a second, different grain size from the first grain size, if necessary, simultaneously feed the classifying and fractionating device, which then provides appropriate material fractions. Other uses become the specialist familiar with track construction work without much thought come up immediately. The person skilled in the art will also immediately recognize that the Above explained on the basis of track construction work without further ado Construction work in connection with any other line construction site, for example a road construction site, is transferable.

6 shows an embodiment variant of the track treatment device 80 with two excavation chains 82a and 82b. The take-up chain 82b takes for example, the ballast bedding and the receiving chain 82a for example, the gravel substructure (such as earth building materials). The one from the Excavated chains are separated from each other via conveyors 84a or conveyors 84b in each case assigned receiving box 40g or 42g of a conveyor and silo wagon 10g passed, the one in the working direction or conveying direction A trailing wagon of a chain of wagons of the corresponding type is. The ballast thus fed into a chain of lower storage boxes and the substructure excavation thus supplied to a chain of upper receiving boxes can, for example, in a continuous loading and unloading cycle 3 are transported away from the track construction site. It is also possible to use the track treatment device 80 with a material preparation device equip or a separate material processing wagon, about between the rail treatment facility 80 and the chain of silo and conveyor wagons to provide for the excavation at least one of the conveyor chains by fractions or component materials to separate and / or recycle and so material or materials or to win material fractions that can be reused at the track construction site can be, so accordingly less new Material from the feed side (wagons 10a and 10b) are fed got to.

With the two excavation chains 82a arranged in the track treatment train and 82b according to FIG. 6, the entire track ballast and that cannot be sufficient stable substructure removed and in the working direction of the machine via a conveyor belt system on rail-transport vehicles, in 6 the two-story conveyor and silo wagons loaded and transported to an external processing plant or completely disposed of become. To save material, transport and disposal costs, it is advantageous if the excavated gravel is in a rail-accessible Ballast processing device of the track treatment train worked up so far for example by sieving and re-breaking depending on the degree of contamination for reinstallation in the Track is suitable and accordingly as an installation material on one corresponding section of the track treatment train is provided. In the case of heavily contaminated gravel, especially gravel with clayey ones Soiling, however, the problem arises that highly cohesive material remains on the gravel, with clay components both in the Funding as well as on sieve arrangements to loam bolls (gravel-like Balls) that cannot be screened off and thus the processing the gravel into question. Working up the ballast is furthermore characterized by clay-like and firmly adhering to the gravel grains other contaminations questioned. The solution is the Integration of a clay separation device and a ballast washing device in the track treatment train. The clay excretion device should serve, in particular, the clay bolls mentioned to remove the gravel. The washing facility is used on the gravel adhering dirt components, for example adhering clay or adhering fine components to detach from the ballast.

If the ballast is particularly contaminated by clay, it can however, be that one is due to a refurbishment of the ballast too much time and possibly insufficient quality results waived and the excavated ballast at the recycling plant including the clay separation device and the washing device past and an external processing or landfill supplies. External processing is advantageous in that it is reusable Substances can be separated from the dirty ballast and thus (by reducing the volume of the material to be deposited) landfill costs are reduced.

As explained with reference to FIGS. 4 and 5, one can ensure a materials supply corresponding to high work performance Transport in mixed condition. The material supply with For example, two different building materials (such as planum gravel [PSS] and gravel) can be simplified and there will be metabolic problems avoided. The separation of the substances takes place via a between the stock supply side and the material installation section of the Track treatment train interposed Neustoff separation module, for example the track separating screens 204 and 204 'according to FIGS. 4 and 5.

After separation in the Neustoff separation module, the ballast can still adhering to fine constituents, especially sandy fine constituents, that may be undesirable, for example because they are in their Total quantity of the technical delivery conditions of a customer for Gravel disagree. A solution here is the Neustoff separation module Downstream washing facility, preferably as a track Module is executed.

7a and 7b is an example of an inventive Track treatment train given on the new material feed side of a material installation section of a Neustoff separation arrangement has downstream ballast washing arrangement and on the Material removal and reprocessing side of a material excavation section of the track treatment train one of a ballast processing arrangement downstream clay separation device and one of these downstream ballast washer.

The track treatment train shown in Fig. 7 has the following wagons, Modules or units on: 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 known from the documents DE 32 19 025 C2 and EP 0 096 236 B2 Wagons); if necessary, at least one drive unit (at least a drive car) B with hydraulic supply for further modules or units of the track treatment train, in particular the screen wagon, the excavation chains and the transfer conveyor belts, in particular also the transfer conveyor belts for overburden to wagon A; a screen wagon C with a crusher system that has a pre-screen (e.g. double decker screen) with adjustment device for direct loading (bypass) in case of excess or Ballast contamination, a crusher for sharpening the ballast, and a secondary sieve (for example a monoplane sieve) for sieving undersize having; a track-running ballast washing system (ballast washing module or ballast washing machine) D with a system for removing Clay bulbs (can be switched on as required), a high-pressure intensive shower cleaner (here called cyclone cleaner), a high-pressure washing sieve, a water treatment plant to reuse the water in the washing system and / or for moistening certain intended for installation PSS materials or from old gravel; a track-going excavation and paving machine E with an excavation chain for the old ballast (the track bed of an existing track) and an excavation chain for the track substructure of the track and installation facilities for the reconstruction of the substructure or the ballast track bed made of new material or refurbished Old material; a material supply and stuffing module F with Transfer conveyor belts and material chutes and at least one Stuffer; a separating screen and ballast washing module G with at least a separating sieve for separating mixed gravel and PSS materials and a ballast washing system for washing off the Gravel after the separation of sandy impurities adhering to it; and at least one of the material feed of PSS material (flat gravel) and new ballast-serving conveyor and silo wagons H, for example corresponding to those from DE 32 19 025 C2 and EP 0 096 236 B2 known wagons, where due to the screening plant of the Module G per se does not matter whether the material is in separate fractions or as Gravel-gravel mixture is delivered. The separating sieve is present Washing module G, however, no conveyor and silo wagons accordingly downstream of the wagons 10a and 10b according to FIG. 4, so that the buffering capacity for materials that have already been separated is relatively small. For this reason, the material should be mixed are delivered, the mixing ratio of the demand ratio Corresponds to new materials when installing materials on module E.

It should be mentioned that the representation of FIG. 7 is largely is a schematic representation. For example the section of the module E comprising the old ballast excavation chain 82b in working direction A for problem-free gravel conveying in working direction to be extended. As explained in more detail below, the old ballast over conveyor belts running in an upper area of the train transported forward in the direction of work, for which the gravel accordingly is to be lifted vertically. For this purpose, it could be useful Conveyor belts of the main discharge belt in the joint part between D and E lower to lay. The transfer belts for the ballast run through the upper one Joint part between D and E.

The modules, units or wagons A, B, C and D are used to remove excavated material and for recycling gravel and can collectively as Excavation and recycling plant can be addressed. This In principle, the system can be used in conjunction with any formwork improvement and ballast cleaning machines can be used.

The old ballast and substructure excavating machine E can in principle of be of any design, especially with regard to the design of the excavation devices (Excavation chains) and the formation protection layer and ballast installation device. The foundation excavation chain 82a may preferably can also be used to excavate ballast so that the excavation chains 82b and 82b for a particularly large work output in parallel can be used if only the ballast to renew or to is clean, but the substructure of the track is not replaced.

The stuffing and new material transfer module F can be equipped with at least one Ballast silo and at least one PSS material silo, the silos, if necessary, by means of a correspondingly large ballast chute and a correspondingly large PSS material feed hopper can be formed (PSS = formation protection layer).

Below is the material flow for new material and old material explained, using a track treatment train as a subgrade improvement train (it becomes the ballast and the substructure of a track renewed) is assumed. From the old ballast excavation chain 82b (as well possibly from the excavation chain 82a by means of a connection to the transfer conveyor producing ballast conveyor belts 84b) Old ballast over ballast conveyor belts 84b-1, 84b-2, 84b-3 into a ballast screening plant 300 (for example for gravel 24/60) fed the for example a two-decker screen (preferably of the finger screen type) having. Sieve residues are conveyed via conveyor belts 302 and 304 at least one wagon A (corresponds to wagon 11 of FIG. 4), together with the removed overburden (especially substructure old material), as will be explained later. At the end of the conveyor belt is 84b-3 a bypass conveyor arrangement is provided which enables the old ballast not the screening plant 300, but the conveyor belts 304 Deliver overburden and thus to wagon A when reprocessing of the ballast due to excessive contamination or damage is not useful or not possible.

The excavated substructure material is removed from the excavation chain 82a Conveyor belts 84a-1, 84a-2, 84a-3, 84a-4 the one leading to wagon A. Overburden conveyor belts 304 fed.

A conveyor belt 306 leads from the screening plant 300 to a ballast crushing plant 308. The broken ballast is transported on a conveyor belt 310 fed to a post-screening plant 312 (for example for ballast 24/60), in the undersize, in particular by breaking up in the Crusher 308 undersize, to be screened. The sieve residues (Undersize or post-screening residues) are conveyed by conveyor belts 314, possibly including the conveyor belts 302, the overburden conveyor belts 304 and thus the overburden wagon A fed.

The one corresponding to a desired grain size, that is to say that of the screening plant 312 (for example, as a monoplane sieve) unscreened gravel is conveyed over conveyor belts 316 of a clay boll excretion device 320 supplied, which is also referred to as clay toner. 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 excretes adobe from the gravel, and adobe bulbs that correspond to the nominal grain size of the ballast Have size and are therefore not eliminated by sieving can. The clay balls are speared by the spikes of the spiked roller, removed from the ballast and then stripped from the spiked roller. A bypass can be provided, which enables the ballast on Take the clay toner past, for example if the gravel is not or only slightly is infamous.

The ballast freed from the clay bulbs becomes a so-called cyclone washer 322 supplied in which the ballast in a fall from below is sprayed intensively with rotating high pressure water jets remove heavy dirt. Turbulence becomes coarse dirt effectively removed from the gravel. The gravel falls for example on a rotating disc with high-pressure nozzles, and is then thrown radially outwards due to centrifugal force. It can a bypass can be provided, which enables the ballast on the cyclone washer to pass if the ballast is less polluted. The arrangement may be such that the clay toner 320 and the Cyclone washer 322 shared bypass is provided.

The ballast, if necessary after passing through the clay toner 320 and / or the cyclone washer 322, is then placed on a high pressure washing screen 326, on which the ballast is shaken or vibrated by the washing sieve is promoted and brewed intensively with water from below and above.

In the area of the high-pressure washing screen 326 there are also a in module D. Wash water sedimentation basin with a drainage channel and (at 330) a water tank and a washing water treatment system are provided. The water treatment is preferably as follows: that of the cyclone washer 322 or waste water discharged from the high-pressure washing screen 326 placed in the wash water sedimentation basin so that solid components, especially sludge. In an upper level range water is removed from the washing water contained in the sedimentation tank and the water tank and / or the wash water treatment fed. Via a drainage channel integrated in the sedimentation basin sludge is fed to a sludge centrifuge 324 to remove the sludge to leave the water. The water freed from the mud becomes from the sludge centrifuge, the water tank and / or the wash water treatment fed. There is preferably a separate fresh water tank and a dedicated domestic water tank. From the process water tank or / and lines can be directly from the wash water treatment in the area of the ballast excavation chain 82b or the substructure excavation chain 82a in order to avoid dust formation To be able to irrigate old gravel before excavation. Furthermore, lines in the area of the formation protection layer installation part of module E be guided to moisten PSS material for installation.

The reprocessed and in module D at least one washing or Dishwashing treatment of old ballast, in the following also recycling ballast is called via conveyor belts 332-1, 332-2, 332-3, 332-4 and 332-5 fed a ballast chute 334, the same time serves as a ballast silo. The ballast installation device of the installation part of module E draws both recycling ballast from this hopper if necessary as well as new gravel.

The supply of new material takes place in the following way. The end the at least one wagon H (corresponds to wagon 11d of FIG. 4) pulled material, usually a mixture of new gravel and Planum gravel (PSS material) is transferred to a via a transfer conveyor 340 Screening system 204 "(for example for ballast 24/60) given, for example is carried out with at least one finger sieve. That through the Screening plant as screening residue PSS material is over Conveyor or transfer belts 342-1, 342-2 and 342-3 in a PSS material feed hopper 344 given, which also possibly fulfills a silo function. The The formation protection layer installation device of module E is moved as required PSS material from this chute.

The ballast screened off from the PSS material by the screening plant 204 "becomes via a conveyor belt 346 into a ballast washer 350 of module G supplied, for example, a high-pressure washing filter according to the Has washing strainer 326. The module G is also with at least one Water tank, a washing water settling tank, a drainage channel, a sludge centrifuge and wash water treatment. Intensive prewash using a cyclone washer or the like is usually not required for the new gravel material his. The module can with respect to the ballast washer and this assigned additional devices, however, be designed as module D.

The washed crushed stone is dem on conveyor belts 352-1 and 352-2 Ballast chute 334 fed.

You can also have your own ballast hopper for recycling ballast and provide a separate funnel for the new ballast, for example if you have recycled and new gravel in one want to incorporate a certain mixing ratio.

Would you like that through two ballast washing systems, namely a recycling ballast washing system and a new ballast washer Avoid investment and maintenance costs, so you can use the track treatment train even with a single ballast washer. This ballast washer is then transported by appropriate conveyor belts Both the refurbished old ballast, which may have been freed from clay bolls as well as the new ballast. It would be particularly useful for this the ballast washer in module E, preferably in the area of or the ballast chute. Would you like one conventional excavation and paving machine E could do so For example, think about an elevated conveyor arrangement the new ballast first in the working direction forward over the Feed module E to the washing device 322, 326 of module D, where it washed together with the reprocessed old ballast or is washed off. Appropriate silos can ensure that that the washing facility old and new ballast in a certain Mixing ratio is supplied.

Regarding the car wash 350 it should also be mentioned that one can also provide a bypass to bypass the car wash, so that in the case of delivery of single-variety, not with PSS material mixed gravel may not need a washing treatment can. Regarding those in the washing systems 350 and 322, 326 Sludge can be provided for this to be added to the new PSS material to be installed with this. The washing water treatment can be avoided or the effort for washing water treatment can at least be kept small if one is used Wash water for moistening the substructure material to be installed or used to moisten the gravel to be excavated or excavated. Fresh water carried in the track treatment train is then primarily for washing the ballast, but not for moistening it of the substructure material or the ballast.
