Abstract

The device has a tramway (3) moved forward on a track (2) that is divided into a short yoke (7) and long yokes (6), The short yoke and then the long yokes are removed based on forward movement of the tramway. A chassis (1) is exchanged after the removal of the yokes, and the yokes are again installed. The respective long yoke is removed at a front end of the tramway. A rear end of the tramway viewed in driving direction is transported after removing the long yoke. The long yoke is again installed at a position where the long yoke was removed, when the tramway again reaches the position.

Description

The invention relates to a method for renewing the multi-layer substructure of tracks according to the preamble of claim 1.

For tracks, the substructure must be renewed from time to time. This consists of at least two layers, namely, for example, a ballast layer and a layer protection layer.

One known method for renewing the multi-layer substructure of tracks provides a work car which stands on the track and is moved forward on that track. To renew the substructure, a short piece of track, namely the so-called short yoke, and then according to the forward movement of the work vehicle successively extended the long bunk, so that the substructure is accessible. For this purpose, the tracks are separated accordingly, provided they are welded together. If the tracks are made up of track sections that are independent of one another, they already form the long bays. After removal of the yokes then the substructure can be renewed. Finally, the yokes are used again.

The known method for renewing the multi-layer substructure of tracks has the disadvantage that it is a discontinuous method. Because the work car is moved forward step by step. In these rest positions of the work car, the longjack is removed, renewed the substructure and then reinstalled the same or another long yoke. In addition to the discontinuity of this procedure exists as a further disadvantage that arise by the discontinuous cyclic forward movement of the work carriage in the substructure inhomogeneities, in which the material is not applied continuously. It thus form interruption points in the substructure.

Based on this, the object of the invention is to provide a faster method for renewing the multi-layer substructure of tracks, wherein, moreover, the renewed substructure should be very homogeneous.

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

Thereby, a method for renewing the multi-layer substructure of tracks is provided, which works very fast due to the continuous forward movement of the work car. In addition, since the work car - as stated - continuously moves forward, the corresponding facilities for applying the layers of the substructure are carried along accordingly. This means that there are no unsteady crossing points. The process sequence looks like that in the front area of the work car, the long bunkers are removed and moved by means of a corresponding device of the work car in the rear, where they are stored. Since the corresponding long yoke is removed, the substructure can be renewed continuously. As soon as the Langjoch, which is temporarily stored in the rear area of the work car, has reached its development point, this Langjoch can be lowered and installed again on the renewed underground. Thus, with the method according to the invention, it is possible to continuously introduce at least two new layers (eg ballast and protective layer). The introduction of these layers can take place simultaneously. The layers are installed without interruption, as well as being reinstalled, even when the work cart is at a standstill. In addition to the continuous installation of the removed track is still a better working height compared to the prior art below the work car available. Furthermore, it is possible through the continuous installation method to allow a laser-guided installation of the built-in appliances when the track is removed with a track-bound guide. Due to the increased working height of the built-in appliances, it is possible to install and compact several single layers of one type of material or several types of fabric by expanding the track yokes with subsequent installation of the layers. In particular, this also represents a tremendous advantage over the track-based techniques which incorporate the layers of the substructure below the raised track only. In these alternatives, the technology of built-in appliances is much more limited in their height construction. The removal and installation of the track yokes can be achieved by lateral lifting of the yokes, ie turning to the side surface or take place via the side surface in a suitable transport position of the work car. As a result, a transport option during machine propulsion to the new installation without delay is possible. It can be used for the application of the layers a market existing Bodenausbaueinheit. Basically it is possible to use the same track yokes. But it is also possible to use new track yokes, which are brought along the work car. In this way, a simultaneous track change in a continuous installation method is possible in the further process step. In particular, it is also possible with the method according to the invention to supply the materials for the subgrade layers in a bypass principle. As a result, a very variable transport of materials along the entire car train is possible.

According to the embodiment in claim 2 facilities for temporary storage and transport of the material for the substructure and work facilities are arranged on or at or below the work car. These can be arranged either stationary with respect to the work car, but also according to claim 3 in the longitudinal direction forward and be moved back. Thereby, a continuous or discontinuous simultaneous incorporation of several new materials from one or two or more directions of delivery is possible.

According to the embodiment in claim 4, the work car is integrally formed.

According to the embodiment in claim 5, however, the work car can also be designed in several parts, ie 2-part or 3-part. These partial work cars are hinged together. Since for those part-work cars, which are located on the developed track-yokes, the support of this partial-work car is missing at the ends, therefore, a crawler undercarriage is provided. This is in the basic position in an upper position. As soon as the corresponding part-work car encounters a surface in which the Jochgleis has already been removed, the crawler chassis is moved down so that it comes to rest on the ground. This crawler chassis serves as a support for this part-work car.

According to the embodiment in claim 6, the material for the substructure seen in the direction of travel is fed from behind and / or from the front. If the material is supplied from the front as well as from the back, three or four layers can be easily installed for the substrate.

The development according to claim 7 proposes that the work car has a length such that it is seen in the direction of travel seen front area equipped so that he can break the long yokes.

For transporting the yokes and / or the individual sleepers, the development according to claim 8 proposes that these be transported laterally along the work cart. By thus transporting the tracks laterally on the track boring machine, this represents an asymmetrical solution.

An alternative to this, namely a symmetrical solution for transporting all materials suggests the development according to claim 9. Accordingly, the building materials for the substructure and / or the working equipment and / or the yokes and / or the individual sleepers are each transported above the work car. This represents the possibility of combining track-bound Umbauzugtechnik with track-bound planning improvement (replacement of the ballast and the ground layers) in the sense that can be transported to the track to be transported and individual sleepers with the incorporated soil materials in the flow of material. This intermittent crossing of materials is highly economical in nature. The intersection of the materials may be accomplished by transporting the tracks above or below or at the same level as the conveyance of the ground materials along the track construction machine. The transport of the ground materials (construction and installation materials) thus does not interfere with the transport of the tracks (yokes and / or sleepers), and vice versa. Overall, with this type of material promotion with the crossing of materials all possible means of transport can be used, namely in particular conveyor belts and gantry cranes.

A technical realization of this intersection of materials provides the development according to claim 10. The basic idea is the use of so-called gantry cranes, which can be moved along rails of the work car on this work car. These gantry cranes can transport a container for the soil materials as well as the yokes and sleepers.

Another possibility for the above-mentioned crossing of the materials suggests claim 11. The basic idea lies in one or more conveyor belts for transporting the building materials. Since these conveyor belts are arranged at a distance above the work car, the above-described gantry crane with the yokes can be moved under them, for example. It is possible to continue to allow the gantry cranes to pass through the gantry cranes while the building materials are being dropped off. It is then only necessary then to clean the yokes. If you do not want to clean it, you have the option of interrupting the discharge of building materials from the conveyor belts until the yokes to be transported have passed the discharge point.

Another variant for crossing the materials suggests the development according to claim 12. The basic idea is that the transport of the ground materials and the transport of the yokes and / or sleepers of the tracks takes place on the same level. For this purpose, conveyor belts are provided for the transport of the soil materials. These are preferably arranged on both longitudinal sides of the work cart. The space between these two conveyor belts for the floor materials is then provided for the transport of the yokes and / or sleepers of the tracks.

All features in the dependent claims 2 to 12 and all features as disclosed in the foregoing description and in the following description of the figures represent independent inventions regardless of the subject of the main claim and can accordingly be the subject of a divisional application.

The working device for renewing the multi-layered substructure 1 (which in the exemplary embodiment has a ballast layer and a layer protection layer) for a track 2 has a one-piece working carriage 3, which can be moved on the track 2 by corresponding end-side rolling devices. This work cart 3 has reservoirs 4 for the substructure materials with conveyor belts 10 for their supply and feeders 5 of the materials for creating the multi-layered substructure. According to the number of layers of the substructure 1, a corresponding number of feeders 5 is provided.

The operation is as follows and will be described with reference to FIG. 2 in 9 steps:

Basically, the working method is designed so that the work cart 3 drives continuously.

In step 2.1, the work cart 3 moves to its working position. In this case, in all drawings, the direction of travel of the work cart 3 to the right. First, the two long yokes 6 and the short yoke 7 are prepared for the expansion.

In step 2.2, the front long yoke 6 and the short yoke is removed.

The work cart 3 moves forward after the removal of the two yokes 6, 7, as can be seen in step 2.3. At the same time the removed long yoke 6 is moved towards the rear end of the work carriage 3, where it is stored for re-installation. The short yoke 7 remains in its position. During the forward movement of the work cart 3, the supplied material for the substructure 1 is installed after this substructure 1 has been previously removed by appropriate machinery. For this purpose, the supplied material from the storage containers 4 of the arranged below the work carriage 3 feeders 5 is supplied.

After the intermediate stored long yoke 6 has again reached its expansion position by the further forward transport of the work cart 3, the long yoke 6 is reinstalled. At the same time, the next long yoke 6 is prepared for removal (step 2.4) and finally removed (step 2.5). During these process steps, the work cart 3 continues to be moved continuously. Furthermore, the material for the substructure 1 is continuously installed during this propulsion.

The newly developed long yoke 6 is now moved back into the rear parking position of the work cart 3 (step 2.6). Subsequently, this long yoke 6 is reinstalled, as well as the short yoke 7 (steps 2.7 to 2.9). The installation of the short yoke 7 is only intended to show how this short yoke 7 is installed. In reality many more long yokes 6 will be installed before.

It should also be mentioned that, of course, after the application of the materials appropriate leveling and compressor units are active.

The embodiment in Fig. 3 differs from the embodiment of the Fig. 1 only in that here additional reservoir 4 and 5 feeders are provided. The supply for these additional reservoir 4 is done from the front. In order to it is possible that the substructure 1 can be made of four layers. Otherwise, the workflow is the same as in Fig. 2 described.

The embodiment in Fig. 4 differs from the embodiment in Fig. 1 in that the work car 3 consists of two partial work cars, which are hinged together. In this case, the front part-work car on a crawler chassis 8.

Here's how it works:

Step 5.1 shows how the work cart 3 moves into the working position and the front long yoke 6 and the short yoke 7 are prepared for removal. The two partial work cars rest with their chassis on the tracks.

Step 5.2 shows the expansion of the long yoke 6 and the short yoke 7. These are placed on the work car 3 in its transport position. Furthermore, the crawler undercarriage 8 is extended downwards and deposited on the ground. Overall, the machine is adjusted in height. Due to the crawler chassis 8 of the work car 3 is still fully roadworthy.

Step 5.3 shows how the long yoke 6 and the short yoke 7 are moved backwards. Since the work cart 3 is in a continuous forward movement, the layers for the substructure 1 are installed and compacted.

In step 5.4, it is shown that the work cart 3 has reached the position of the next long yoke 6 with its front part work cart. This front long yoke 6 can now be removed for the next stem section. The longjack 6 located behind it has in the meantime reached its parking position on the rear part of the work vehicle 3.

In step 5.5, the rear "parked" long yoke 6 is reinstalled, since in the meantime the work car 3 has reached the position of the newly built substructure 1. The just removed front long yoke 6 is transported to the rear. At the same time, the layers for the substructure 1 are applied again.

Step 5.6 shows the position of the last built-in Langjochs 6. Here then the chassis of the two part-work car 3 again have the opportunity to drive on the built-in tracks. This means that the crawler chassis 8 is raised again.

Finally, step 5.7 shows that the short yoke 7 and the last long yoke 6 are installed to close the gap.

Also in this embodiment of the work cart 3, the material can be supplied from the front for the installation of more than two layers for the substructure 1.

The variant of the work cart 3 in Fig. 6 shows that this is formed in three parts. The two front part work cars are each equipped with a crawler chassis 8.

The operation is as follows:

Step 7.1 shows that the work cart 3 is in its working position. The front long yoke 6 and the short yoke 7 are prepared for removal.

In Fig. 7.2 can be seen that the short yoke 7 removed and placed in the transport position. The crawler chassis 8 of the middle part of the work vehicle is extended down to relieve this car and support. Furthermore, the front car and the middle car is bolted.

In the further steps 7.3 to 7.8 can be seen how the individual long yokes 6 expanded, transported to the rear and re-installed, as the same time the substructure 1 is applied with its layers and how to support the two front part-work cars caterpillars 8 down are extended. Finally, in step 7.8, this situation is shown after completion of the renewal process, that is, when the last long yoke 6 and the short yoke 7 have been re-installed to close the gap and all the chassis of the three sub-work car rest on the track 2, so that the crawler tracks 8 are moved up.

Fig. 8 shows a further modification of the work car. For the transport of soil materials as well as for the yokes 6, 7 serve gantry cranes 9. These are on corresponding rails along the trolley 3 movable. They span the top of the work cart.

The operation with reference to FIG. 9 is as follows:

In step 9.1, the work cart 3 moves to the working position. The track yokes, namely the Langjoch 6 and the short yoke 7 are prepared for the expansion.

In step 9.2, the long yoke 6 and the short yoke 7 are removed and placed in transport position. Furthermore, the crawler chassis 8 is discontinued and the work car 3 adjusted in height. It can be seen that the elongated yoke 6 is received by the gantry crane 9.

In step 9.3, the gantry cranes 9 located on the left side pick up from the left direction of the material bucket. The gantry crane 9 with the long yoke 6 moves to the left to the tilting edge of the bulk bucket. The paver finishers are discontinued and begin with the installation.

In step 9.4, the left gantry crane 9 fetches further material bucket from the left direction and moves away to the left in a corresponding transport cycle. The gantry crane 9 with the long yoke 6 moves to the left over the installation point and lowers the long yoke 6 from. The pavers continue to build material, because the work car 3 - is still moving forward - as before.

In step 9.5, the gantry cranes 9 go back from the left direction after they have taken appropriate material bucket. The gantry crane 9 for the long-yachts 6 moves to the right to over the construction site and begins with the expansion of another long yoke 6. Again, the installers continue to build their material.

In step 9.6 is again shown how the left gantry cranes 9 feed from the left direction Materialkübel. The gantry crane 9 for the long-yachts 6 moves to the right until over the construction site and begins with the expansion of this long yoke 6. The pavers continue to build material.

The steps are repeated successively until the complete substructure 1 for the track 2 has been renewed. In step 9.7 is shown how the last long yoke 6 and the short yoke 7 are reinstalled as a gap closure. The pavers and remaining equipment are brought into transport position.

The Fig. 10a shows a plan view of the work car 3 of 8 and 9 , It shows how the track yokes are transported. The representation in Fig. 10b shows the same situation, but in the transport of single sleepers.

Fig. 11 shows a further embodiment using gantry cranes. However, these serve only to transport the yokes 6, 7. For the supply of soil material are Conveyor belts 10 are provided, which are arranged at a distance above the top of the work cart 3.

The basic principle here is that the gantry cranes with their yokes 6, 7 can pass under the conveyor belts 10.

The last variant is in the Fig. 12 and 13 shown. Here no gantry crane 9 use, but rather conveyor belts 10, 11 and 12th

The feeding of the soil material takes place here again via conveyor belts 10. These deposit the soil material on two conveyor belts 11, which are located in the side regions along the work carriage 3. From there, the soil materials are discarded at the installation site.

Between the two conveyor belts 11, a further conveyor belt 12 is provided. This serves to transport the yokes 6, 7 and the sleepers. The procedure is again the same as described above. The difference is only in the transport systems for the objects to be transported. The steps are thus the installation of the long yokes 6, bring expansion of the long yokes 6 in transport position, build underground layers and propel 3 work car.

Fig. 13a shows a plan view of this conveyor belt technology during the transport of track yokes. It can be seen that the removed track yokes are transported in the middle of the conveyor belt system on the work car 3 to the new location and installed here. Above all, it can be seen that the introduced flooring materials and the track elements to be installed intersect without interrupting the power stroke. Crossing of fabrics as shown in Fig. 13a can also be done with twisted or asymmetric position of the yoke to the track axis, namely in design-related dependencies. It can be both a developed long yoke 6 come to install and a new long yoke. 6

Fig. 13b shows the transport of single sleepers.

The variant in Fig. 13c Finally, it shows the transport of single sleepers with penetrating sleepers. As a result, the conveyor belts can be made wider.

In all variants, the arrangement of the conveyor belts, the material task or other technical components can be moved in their position and also changed. For example, the location of the above-described conveyor belts on a Page 3 of the workbench 3 and the location of the transportable material on the other side. For example, the position of the track yokes to be transported may also take place at the altitude below or above the elevation of the conveyor belts.
