Abstract

The method is for reconstruction of a track with track bed (16), ballast (15), and rails (18), or conversion of such a track into a permanent way. Ballast and track bed are removed to a certain depth, partially removed and/or regenerated, new ballast (26) or a sub-base for a permanent way are constructed, and the old track is replaced by a new track (25). All steps for reconstruction or conversion are carried-out in one single phase, and in one working direction (I) only.

Description

The present invention relates to a device for the renewal or conversion of a track system according to the preamble of claim 1.

When renewing track systems with ballast, various devices are usually used, which are used successively according to their purpose. Thus, first a device for removing the old ballast bedding and possibly the substructure is threaded into a track system and driven over a certain section. Subsequently, a track change device is used, which exchanges the old track laid by the Bettungsaushubvorrichtung for a new track. In this case, either a new gravel planum is produced by the ballast excavator or by the track changer. As the third device, a track tamping machine is then threaded, which aligns the new track, einschottert and stuffs the ballast.

The requirement of at least three devices, which are used successively in a construction section, the known method is costly and time consuming. Several operations must be performed, each requiring a threading and unthreading of the device used. This will lose time. In addition, the devices used can work only partially track-bound, so that the supply and removal of material, including building materials and Thresholds must at least partially be done by truck. This is a serious environmental impact and poses significant logistical problems. In processes for converting a track system in a solid lane, these problems occur even more.

An apparatus according to the preamble of claim 1 is known from US-A-3 685 456.

The invention has for its object to provide a device of the type mentioned an increased functionality.

This object is solved by the features of claim 1.

The device according to the invention for renewing a track system is therefore largely identical to the device according to the invention for converting a track system into a fixed track. The only difference is the use of a part for producing a supporting layer of a fixed carriageway instead of the parts for producing the new ballast and for ballasting and plugging the new track in the renewal of a track system. In the manufacture of such a device costs can be saved. When converting the track system in a solid lane, however, unlike the renewal, not all parts are used simultaneously. Rather, the part for conveying away the old sleepers and for promoting the new sleepers and the track change part are used only in a separate operation.

It is advantageous that the parts of the device are formed at least partially interchangeable modular. A device for renewing a track system can be converted in a cost-effective manner in a rebuild train for the conversion of a track system in a fixed lane and vice versa. Essential parts can be taken over and need not be manufactured separately.

In particular, the module for producing a new bedding, optionally the module for temporarily storing refurbished bedding material and optionally the module for supplying new bedding and possibly substructure material on the one hand and the module for installing a support layer for a fixed carriageway, optionally the module for supply Support layer material and optionally the module for mixing of base layer material on the other hand designed to be interchangeable.

Preferably, the device according to the invention additionally comprises a part for removing the substructure, a part for processing the bedding and / or the substructure material, means for breaking and screening the bedding and / or the substructure material, a part for temporary storage of the reclaimed bedding material, means for holding and transporting material for the support layer of a fixed carriageway and / or a part for mixing the base course material. By integrating the parts and means mentioned, the corresponding method steps can advantageously be carried out on site. This allows recycling of the materials and reduces the removal and transport of material.

According to a further embodiment of the invention, the part for conveying the old sleepers and for promoting the new thresholds seen in the direction of the rear end of the device, the part for promoting new bedding and possibly substructure material, the part for conveying the ballast and optionally of the substructure material and the part for feeding the base course material at the front end of the device. Such an arrangement is advantageous for the workflow.

It is preferred if only the track change part and the part for installing a support layer of a fixed carriageway in addition to rail bogies and ground bogies, the other parts, however, all only have rail bogies. The burden of the substructure or the reason is kept as low as possible.

The device shown in Figs. 1 and 2 consists of a series of modules that have been put together for the renewal of a railroad track with ballast bedding. Provided and illustrated seen in working direction I from the front to the back of a disposal module 1, a supply module 2, a drive module 3, a excavation and Bettungsaufarbeitungsmodul 4, a buffer module 5, a small iron module 6, a DC module 7, a plug module 8, a threshold supply and removal module 9 and a further supply module 10.

The disposal module 1 comprises in the illustrated embodiment, two material conveying and silo cars 11 for the removal of excavated material. These each have a conveyor belt 11a and a transfer belt 11b and can thus be successively filled with excavated material. Of course, if necessary, more or less such material conveying and silo cars 11 may be provided. In addition, other facilities for the removal of materials can be used.

The illustrated supply module 2 also comprises two material conveying and silo cars 12, which are, however, arranged in reverse. The material conveying and silo wagons 12 are used for the provision and delivery of supplementary ballast and the forwarding of excavated material to the disposal module 1. For this purpose, additional transfer bands 12c are provided. Again, more or less than two material handling and silo cars 12 or other suitable devices can be used.

The illustrated device is driven by the drive module 3, which is formed in the example shown by a locomotive-like drive unit 13. It can also be provided more drive modules 3, or the drive can be distributed to the other modules.

The excavation and ballast processing module 4 is subdivided into an excavation module 4b and a ballast processing module 4a. Thereby, if desired, the bedding processing module 4a can be omitted to use only virgin material. The excavation module 4b comprises in addition to the excavating device 14 for removing the bedding 15 and optionally the substructure 16 also a track lifting device 17 to lift the track 18 during the removal of the ballast 15 and the substructure 16. The track 18 is then placed either on the base 16 or the ground, or the module 4b additionally includes a preferably turn-off device 17a for producing a new gravel roadway on which then the old track 18 is stored.

In particular, the bedding preprocessing module 4a comprises a pre-screen, a crusher, and a defluxer for excavated ballast and substructure, and, like the excavation module 4b, suitable conveyors 20a, all summarized by reference numeral 20. The stages of pre-screen, breaker, and fore-screen are preferably as needed adjustable.

The temporary storage module 5 serves to temporarily store excess refurbished ballast 19, which may later be used in the event of a defect in the manufacture of the new ballast bed 26. In particular, a carriage 21 designed as a bulkhead silo is used.

The ironing module 6 serves to protect workers who are integrated into the process to solve the small iron with which the rails 23 are attached to the thresholds 29.

The track change module 7 includes as a module 7a a Schwellenaus- and -einbaumodul to remove the old thresholds 29 and for installing new sleepers 30, wherein preferably a device is provided to rotate the thresholds 29, 30 so that it transports in longitudinal direction to the track system can be. The module 7a also includes a device 22 for exposing the old rails 23. The module 7b is used the direction of the new sleepers 30, the insertion of laterally upstream new rails 24 and the attachment of the iron.

The gravel pot module 8 is used for ballasting the new track 25 and for stuffing the new bedding 26. The new track 25 is also fine-lined. Both modules 7 and 8 also have conveyor belts 35 and 36 for conveying the old sleepers 29 and the new sleepers 30, the module 8 additionally a conveyor belt 37 for the delivery of additional ballast from the module 10th

Finally, the threshold supply and disposal module 9 and the ballast supply module 10 serve to supply and discharge thresholds as well as supplementary ballast. The threshold supply and disposal module 9 comprises a transfer trolley 27 and a threshold wagon 28 for storing new sleepers 30 and for collecting the old sleepers 29. In addition, gantries 28a for transporting the sleepers 29, 30 and the supplementary scraper are provided, which are connected by means of crane track rails and ramps between Schottersilowagen 31 and transfer car 27 are movable, which is provided with three conveyor belts 27a, b, c for Altschwellen 29, Neuschwellen 30 and supplementary ballast. Of course, if necessary, several threshold cars 28 may be provided.

To renew a track system with ballast bed 15, the device shown is threaded into the track system and brought in the direction of work I used. The transport to and from most of the materials takes place by rail, and material that has been removed from the material handling and silo wagons 11 and 12 is conveyed away in the direction of work I and removed and not reused. The of the track change module 7 old sleepers 29 are, on the other hand, transported away in the direction of work I to the rear. The old sleepers 29 are stored for this purpose in the carriage 28 and transported away with this. The new sleepers 30 are also fed in the direction of work I fed from behind. For this purpose, they are transported to the threshold carriage 28. Supplementary ballast can also be transported from behind via the ballast carriage 31.

The gravel 15 removed by the excavation module 4b is pre-screened in the refurbishment module 4a, crushed and screened. Subsequently, a new gravel planum 26 can be produced with the module 4b from the refurbished ballast 19. For this purpose, in addition, new ballast, in particular for Kornergänzung, are used, which is fed from the material conveyor and silo truck 12 seen in the direction of work I from the front. If, on the other hand, excess slag 19 is produced during the workup, it is temporarily stored in the ballast silo 21 in order to be able to be reused at a later time.

In the track change module 7, the old rails 23 are exposed to the side, the old thresholds 29 added, new thresholds 30 deposited on the gravel, used laterally upstream new rails 24 and finally installed in the new thresholds 30. In the area in which the suspension of the old rails 23 and the insertion of the new rails 24 takes place, the track change module 7 has one or more pairs of tracks 32 as ground bogies. Moreover, the track change module 7 as well as all other modules 1 to 6 and 8 to 10 exclusively rail bogies 33.

Following the installation of the new rails 24 in the new sleepers 30, the new track 25 is eingeschottert in Stopfmodul 8, fine-finished and the new bedding 26 stuffed. As a result, a drivable track position is created, which is suitable for the removal and transport of sleepers 29, 30. Thus, substantially the entire supply and removal of material, including old and new waves 29, 30, track-bound done. After the removal of the old track 18, the new gravel planum 26 is preferably post-graded and post-compacted before the new sleepers 30 are laid. The graveling of the new track 25 is carried out in particular with Neuschotter from the Schottersilowagen 31, which is transported in buckets from the gantry cranes 28a on the ballast conveyor belt 37 and from there to the stuffing module 8. When gravel and plug the new track 25 also takes a direction of the track position. For this purpose, suitable lifting and straightening devices are available, which are not shown here.

The modular structure of the device shown and described also allows a simple design without a device for processing the removed material, if this should not be desired. In this case, the refurbishment module 4a is omitted. The other modules 1 to 10 can be partially omitted. For example, the intermediate storage module 5 for reclaimed ballast 19 can also be omitted.

Another possibility is to compile instead of a device for renewal of a track system with ballast bed 15 a Umbauzug for the conversion of the track system in a fixed lane of corresponding modules. Such a compilation is shown in Figs. 3 and 4.

This Umbauzug shown in Figs. 3 and 4 comprises a first part II and a second part III, which are shown here together, but used separately. The first part II is used in the working direction I first, while the second part III is used subsequently and in the opposite direction of work IV.

The first part II includes seen in the direction of work I from front to back again a disposal module 1, a supply module 2 ', a drive module 3, an excavation and refurbishment module 4 and a base course production module 5'.

The disposal module 1 is consistent with the disposal module 1 of the device shown in FIGS. 1 and 2. By contrast, the supply module 2 'now consists of two different submodules 2'a and 2'b. The module 2'a is a silo wagon 12 'for providing cement and water, and the module 2'b is a silo wagon 12 "for providing supplementary material for producing a supporting layer of a fixed carriageway, both of which are provided with suitable conveying means 12 'a and 12'b and equipped with transfer bands 12'c.

The excavation and refurbishment module 4 also coincides with the module 4 of the first device. However, now the screens and crushers for processing the bedding and possibly base material are adjusted to the base layer of the solid track to be produced, that is, to the required grain size and composition of base course material. And the bedding production device 17a is turned off.

An essential difference is in the module 5 ', which now also consists of two sub-modules 5'a and 5'b, namely a mixing device 5'a for mixing the material for the supporting layer of the fixed carriageway and a module 5'b for installation of these base course. The mixing device 5'a is used to mix the base course material of the reclaimed material and any new material supplied and cement and water.

With the base course production module 5'b, a base layer 34 of a fixed carriageway, in particular an unbound or hydraulically bonded lower base course, is produced. On this support layer 34, the old track 18 is stored.

In the case of Umbauzuges shown in FIGS. 3 and 4, the old track 18 after the removal of the ballast 15 and possibly the substructure 16 initially placed on the substructure or the ground. The removed material is worked up as in the variant of FIGS. 1 and 2, but with a correspondingly different grain size in accordance with the prescribed grading curve for an unbound or bound support layer 34. In this case, excess material is moved forward in the working direction I over the material conveying and silo wagons 11, 12 transported away. For the production of the base layer 34, the reclaimed material, optionally mixed with new material transported from the front in the working direction I from the module 2'b, as well as cement and water from the module 2'a in the mixer module 5'a. The support layer 34 is then produced from the finished base course material in the base course production module 5'b.

In order to allow a sufficient setting of the support layer 34, the device 5'b for producing the support layer 34 has a pair of caterpillars 32 as floor landing gear. In addition to installation, the base layer 34 is also compressed in the base course production module 5'b. Immediately after the production of the support layer 34, the old track 18 is placed on it.

The second part III of the device according to FIGS. 3 and 4 comprises a small iron module 6, a track change module 7, a threshold supply and removal module 9 and a material supply module 10 '.

The ironing module 6 is consistent with the iron module 6 of the device according to FIGS. 1 and 2 match. It serves as there to protect workers, who now attach the new rails 24 to the new sleepers 30 with the iron.

The track change module 7 also agrees with the track change module 7 of the previous device. Only the arrangement is now reversed, corresponding to the changed working direction IV, and in the module 7b the iron is released.

The threshold supply and removal module 9 also includes here a transfer car 27, a threshold car 28 and gantry cranes 28a.

Thus, the replacement of the old track 18 in a second operation in the working direction IV can be carried out with substantially the same modules that were used in the device according to FIGS. 1 and 2 in the one operation in the working direction I. The completion of the fixed carriageway is then carried out in a further operation with a suitable device, for example, a fixed carriageway with laid on an asphalt or concrete layer track grid or a fixed Roadway with embedded in an upper support layer of concrete sleepers or plates can be made.

Due to the modular design of the device according to the invention, an existing track system with ballast bed 15 and sleepers 29 of all types of construction can be skillfully renewed in one operation or prepared for conversion to a solid lane of different construction methods to the production of the lower support layer. In the production of a fixed track, a part of the device can also be used in a second operation to replace the old track 18 against a new track 25. Due to the modular design, the device can be adapted to the respective needs. The costs remain relatively low.

The device according to the invention also has the advantage that the supply and removal of the materials including the old and new waves 29, 30 can be made at least predominantly on the track without affecting the operation in the neighboring track. By transport predominantly over the rail parallel to the track running construction roads can be saved and the truck traffic is at least reduced. There is less construction site space required and the environmental impact is significantly reduced. By processing the dismantled materials disposal costs for existing materials and corresponding transport services can be saved. Due to the track-bound transport also less weather-related interruptions of the workflow occur.
