Description

The present invention relates to a rail change train for Remove old rails installed on sleepers and replace them New rails.

Rail tracks must be at intervals of several years, i. e. the worn old rails must be replaced with new bars. In the older state of the art this was done regularly in such a way that initially a trolley loaded with new rails, For example, a so-called long rail unit, the rail route drove along, and the Neuschienen loaded next to the next used old rails were unloaded. In a later operation then the rail change was essentially done by hand Transfer blocks or two-way dredgers performed. The removed old rails were in a further operation, for example by means of a crane on a especially for this provided old rail dolly loaded and transported away, if necessary after crushing on the construction site. Finally, in in a further step, all necessary welding, i. the Connection of newly laid on the sleepers new rails with each other and with the remaining track to be used and therefore left behind, carried out.

These numerous individual steps each required separate blocks the construction site as well as multiple planning, logistics and locomotive performances as well each separate site supervision, site security, acceptance, Billing, etc.

• einen in Betriebsfahrtrichtung des Zugs hinter einem Neuschienen-Transportwagen anzuordnenden Übernahmewagen mit Übernahmemitteln zum Ergreifen und Abziehen von auf dem Neuschienen-Transportwagen geladenen Neuschienen, und
• einen in Betriebsfahrtrichtung des Zugs hinter dem Übernahmewagen angeordneten Schienenwechselwagen mit Ausbaumitteln zum Ausbauen der Altschienen hinter einem vorderen Drehgestell des Schienenwechselwagens sowie Führungsmitteln zum Führen und Absetzen der Neuschienen auf Schienenauflager auf den Schwellen vor einem hinteren Drehgestell des Schienenwechselwagens.

In order to be able to summarize at least some of these originally separate work steps, a rail change train has already been proposed in the prior art for removing old rails laid on sleepers and replacing same on new rails, comprising:

• a to be arranged in the direction of travel of the train behind a Neuschienen-Dolly transfer car with transfer means for gripping and removing loaded on the Neuschienen-Dolly Neuschienen, and
• arranged in the direction of travel of the train behind the transfer car rail car with expansion means for removing the old rails behind a front bogie of the rail car and guide means for guiding and discontinuing the new rails on rail support on the thresholds in front of a rear bogie of the rail vehicle.

Such a rail change train is described for example in the DB textbook "Working methods for the maintenance of the superstructure", 5th ed., Eisenbahn-Fachverlag Heidelberg / Mainz, 2000 (ISBN 3-9801093-7-2). The train is coupled behind a trolley loaded with Neuschienen, which again from a locomotive over the still on the rail supports on the Swell-mounted old rails is pulled. As soon as the beginning of that section of the route is reached, in which the old rails through the New servants are to be replaced, a troop of workers comes along Dismantling equipment in front of the locomotive and begins with the dismantling of Fasteners, mainly screws and clamps. These Dismantling work, for example, with known screwdrivers be carried out as also presented in the said DB textbook become. In addition, the old rails to be removed from the so-called Start of construction, i. the place from which the old rails are to be replaced, from the remaining to be used and therefore remained old rails separated, such by sawing.

After dismantling the old rail fasteners remain the Old rails, however, still initially on the rail supports on the thresholds lie. The locomotive and the operating direction of the train on the Locomotive following Neuschienentransportwagen as well as the subsequent Transfer cars and the final rail car change each time about these no longer fortified old rails. The locomotive pulls the Rail change train then so far before that the start of construction between the front and the rear bogie of the rail car, which is the Completion of the known rail exchange train forms. In other words, stands then only the rear bogie of the rail car the old rail section that is preserved.

Then with the help of the means of takeover on the transfer car First, Neuschienenpaar deducted from the Neuschienen-Dolly, in one suitable bending line by the transfer car to rail car pulled and guided by respective management means and finally under the rail car to the end of the remaining old rail connected, for example with the help of a so-called Schienenexzenterlasche. These are the "disturbing" to be built old rails from the beginning of construction to the front bogie of the rail car removed the expansion means, in particular spread to the side or pressed Service.

As soon as this first end of the new rails with the free end of lying old rails has been connected, the entire draws Neuschiene due to the pure locomotion of the rail shuttle in Operating direction automatically from the Neuschienen-Dolly from and is on the rail supports placed on the thresholds, in each case shortly before the rear bogie of the rail car. This rear bogie of the rail car is thus the only bogie of the entire Railcar, already on the "freshly laid", but not yet on the new sleepers fastened to the sleepers drives; all other bogies, i. the front bogie of the rail car, all bogies of the Transfer car and the Neuschienen transport vehicle and the entire Locomotive still drive on the immediately after to be built and already dissolved old rails.

This generic rail change train thus allows the Summary of several separate in the older art Operations to a single joint step, namely the Transporting and unloading the new rails in the track, removing the to be replaced old rails and the discontinuation of the new rails on the this expansion freed rail support on the thresholds.

However, the use of the generic Rail change train also considerable disadvantages: in particular is a to see considerable risk in that the locomotive, the Neuschienen dolly as well as the entire attached rail change train with Transfer cars and rail carts over largely unpaved Need to drive old rails. As explained above, the old rail fasteners in this system yes by one in front of the locomotive working group of workers dismantled with suitable dismantling equipment. at even and straight stretches is the risk, the locomotive and the mentioned Car over unfortified old rails to drive, justifiable, just at However, there are some winding roads on a slope or with a gradient considerable risk that an unfortified old rail under that of the Locomotive or a truck-loaded load overturned, causing the derailment of the entire train can lead. For this reason, the generic Rail change train in such routes hardly to remove old rails and replacing them with new rails.

It is therefore an object of the present invention to provide a generic rail change train such that he also can be used on more difficult routes, through Minimizing the length of unpaved rails over which the train has to travel.

According to the invention, this object is achieved in a generic Rail change train solved in that he behind in operating direction the transfer car and before the Ausbaumitteln the rail car arranged disassembly unit for dismantling old rail fasteners having.

This disassembly unit according to the invention allows namely, the Old rail fasteners only immediately before actual removal the old rails with the help of the expansion means of the rail car to disassemble. For this purpose, it is sufficient that the inventive Disassembly unit more or less immediately before the expansion means of the Rail car is arranged. The inventively provided Arrangement of the dismantling unit behind the transfer car thus allows it in contrast to the rail change train known from the prior art, especially the particularly heavy vehicles of the overall system over to drive fixed old rails, namely the locomotive and the heavy loaded Neuschienen-Dolly. Also, usually less severe Transfer car still drives on old rails, and if the Disassembly unit is provided on the rail car itself, can even still the front bogie of the rail car on continue drive fixed old rails. When rail change train according to the invention is Thus, unlike the prior art, it does not require heavy Vehicles such as the locomotive or the fully loaded Neuschienen-Dolly to drive over unpaved old rails. Therefore, the inventive rail change train even with curvy, steep or off other reasons complicated track gradients are used reliably without a derailment of the train is to be feared.

In a simple embodiment it is provided that the Dismantling a directly above the threshold working platform includes. On it can be the workers dismantling the fasteners stop, or sit on it and reach down to the thresholds.

To release the old rail fasteners is expediently provided that the disassembly unit on the rail supports the thresholds includes lowerable disassembly devices. These are in particular known screwing machines, for example also multi-spindle screwdrivers, as explained in the above-mentioned DB textbook and allow the simultaneous unscrewing of several sleeper screws. Optionally, such a disassembly device by means of a kind Rail guide provided in the longitudinal direction movable in the disassembly unit be so that the rail change train also during the dismantling of Old rail fasteners continue its slow continuous ride can.

As already briefly mentioned above, the disassembly unit basically be arranged on the rail car itself, in particular immediately before the expansion means for removing the old rails (here and in the Throughout the description, the terms "before" and "behind" are basically related to understand the operating direction of the train). Then that is also possible front bogie of the rail car still on fixed old rails drive. However, this bogie is usually not so heavily loaded, that it could not drive over unpaved rails. In addition, the Space between the bogies of the rail car for the actual rail change, so the removal of the old rails and the Placing the new rails on the rail supports needed, so that a additional disassembly unit in this position could interfere. In a expedient development of the rail shuttle according to the invention Therefore, the dismantling unit on a in operating direction before the Rail car arranged dismantling carriage provided. This Dismounting car can then be specially designed for optimal operation of the Disassembly devices are designed, and the place under the Rail car is completely for the actual Rail replacement available.

In a particularly advantageous embodiment can be provided here be that demountable one between its bogies raised frame and possibly attached to the frame work cabin includes. Under the raised frame creates a working space for the Dismantling equipment operating personnel. The work cabin can be transported serve these personnel or to accommodate disassembly unit accessories.

As already mentioned in connection with the generic Rail replacement explained at the beginning, the new rails are by the Forward movement of the train automatically deducted from the Neuschienen-Dolly, as soon as the foremost newcomer ends in the so-called "threading phase" has been connected to the end of the remaining old rail track. in this connection is, as also mentioned, the withdrawn Neuschiene by various Guide means, in particular on rail car, but also on Disassembly car according to the invention, guided in such a way that they have a relatively "gentle" bending line to excessive Avoid material stress. Since the inventive Rail change train especially for replacing long rails with a Length of, for example, from 120 m to be used, can be achieved an optimum bending line of the deducted from the Neuschienen-Dolly Neuschienen be provided that the rail change train also a arranged between the transfer car and the dismantling truck front distance car with guide means for lowering the from Transfer vehicles supplied Neuschienen includes. This distance car serves So essentially, an extra distance between the front Transfer car and the rear dismantling car to create, and the of the Transfer vehicles supplied Neuschienen by suitable guidance means of gently lower the far end of the distance car to its rear end. It It should be mentioned at this point in general that as a guide in particular horizontally and vertically mounted rollers are used.

What now the course of the new tracks of her behind the locomotive arranged trolley until its settling on the rail supports is concerned, different courses are possible, which in particular with regard to the question of what space requirements on the dismantling unit, for example, on the specially provided dismantling truck, it is expected:

Thus, in one possible embodiment of the invention Rail shuttle provided that the takeover means of the Transfer car and the guide means of the front distance car, the Disassembly carriage and the rail car are aligned, that the new rails when driving the rail shuttle on the transfer car spread apart laterally, further spread on the front distance car and lowered under his rear bogie and around the dismantling truck be led around. In this embodiment, in the dismantling truck extra space for disassembly work available, which is e.g. then from great advantage can be if with some disassembly difficulties is calculated, so that about the expected times for solving the Old rail mounting screws are larger than usual.

If no such disassembly difficulties are to be expected, offers Another embodiment of the invention Schienenwechselzugs at which the takeover means of the takeover vehicle and the management funds the front distance car, the dismantling car and the Rail car are aligned so that the new rails when driving of the railroad exchange on takeover wagons, front distance wagons and Dismantling are each performed in the area of the track center. Thus stands Although there is less space available in the dismantling area, this will be the case not necessarily needed. Therefore, you benefit from the advantage of a better easier bending line of the new rails to be unloaded, which continuously in the The area of the track center through the various means of acceptance or Guidance means are led.

Especially in the former case of a leadership of the new rails around the dismantling cart around and thus a required spread of Neuschienen on the front distance car, but also on the second Embodiment with a guide of the new rails in the region of the track center It makes sense that the frame of the front distance car between the Front and rear bogie a smaller width across the Operating direction than in the field of bogies, in particular in the second embodiment then in the bottom of the front spacer car Openings for passing the new rails can be provided. One such distance car with a narrow in the direction of travel frame facilitates the first-mentioned embodiment, the spreading and simultaneous lowering of the Neuschienen at the edges of the front distance car, and at the same time this front spacer car in a rail shuttle according to the second embodiment are used, in which case the new rails by the openings in the ground are threaded through.

As can be seen from the above, the front one Distance wagons - as its name implies - essentially intended a certain distance between the transfer car and the Dismantling to create, so Neuschienen on a larger horizontal distance can be lowered and thus the optimal Can go through the bend line. As a rule, however, no special burden arises rest the front distance car. It is therefore always possible, but not absolutely necessary to use the distance wagon as a separate wagon to provide a dedicated only to him front and rear bogie. Rather, the rear bogie of the front spacer car as a front Be designed bogie dismantling the car. In this case, that is almost the case rear end of the front distance car via a hinge connection on the front bogie of the dismantling truck. If necessary, can also on front end of the distance car in place of a standard bogie one Single axle be provided, as there are no particularly large loads rest on the distance car.

As already emphasized several times, the draws at the end of the lying old rail adhere to new rail through the pure Forward movement of the rail change train according to the invention automatically along a given by the various guide means bending line from the new bus transport van. Now, to a continuous continuation To enable the Neuschienenverlegung is in a particularly advantageous Further development of the invention provided that on the transfer car a Coupling device for docking together of the Neuschienen-Dolly deducted Neuschienen is provided. Such a coupling device allows it, for example, slowly from the Neuschienen-Dolly withdrawn end of a currently to be laid Neuschiene with a free Beginning area of another, loaded on the trolley Neuschiene connect, so then continue on the inventive Rail change train and the next Neuschiene is automatically deducted.

In principle, it would be conceivable as such a coupling device Provide cable and / or tab connections. Particularly advantageous can However, this embodiment will be used when the Coupling device a welding system, preferably Abbrennstumpfschweiß plant includes. This allows it, namely on the transfer car the end a currently withdrawn Neuschiene with the beginning of one next To be welded new rail to be welded, especially in the rail usual flash butt welding technique. The use of this special Resistance pressure welding process and corresponding, usually stationary Welding systems used are known in the art and also in the described above DB textbook.

These welds are in the art "in the track" performed, i. the new rails are already laid on the sleepers, which Welding system is then introduced and made the weld. The disadvantage here is that shortens a long rail during welding, so that the laid new rails for the intended route "not enough". This disadvantage is due to the inventive weld on the Transfer cars, i. before the actual laying, eliminated.

However, it should be remembered that welding two rails in The welding system needs some time during which the train basically would have to be stopped. To avoid this, and thus one to allow continuous slow ride of the train during the mission can the coupling device, in particular welding system, but also other mechanical coupling device, on a longitudinal direction of Transfer carriage be arranged slidable carriage. During the Coupling process, ie during the flash butt welding, then can the train continues slowly continuously while the Coupling device on the carriage from the front to the rear end of the Transfer car drives and thus the forward movement of the train largely balances. For this purpose, for example, offers a simple solution of a carriage on, on two at the two longitudinal edges of the transfer car arranged auxiliary rails running.

In general, peeling off the new shots from hers Dolly on the transfer car and possibly by a welding system on the take-over by already for the first to be laid To enable new bus during the threading process, i. before you get to that End of the remaining Altschienenstrangs is tied, is expediently mounted on the front spacer car a cable winch system.

As explained above, the disassembly unit is provided with in it Tool to, old rail fasteners and other small parts too dismantle, which are made in particular of metal. To do that in the Dismantling unit working staff not even this iron of Hand picking up can be in a progression of the Rail exchange according to the invention in the operating direction behind the Disassembly provided a magnetic iron collecting device be. As a rule, this is an electromagnetic drum, the attracts metal objects in its lower area and in its upper area fall onto a conveyor belt, from where the metal objects then into a Be promoted container. Such systems are well known and will not to be continued here.

In addition, advantageously on the rail car in the area the expansion means a threshold holding device, in particular one between the Old rails caterpillar track or a runner, over the Threshold surfaces is pulled to depress the thresholds be provided. This avoids that by the expansion means removed old rails, which lifted off the rail supports or the Side, due to adhesive forces take the thresholds or move.

As is well known, rails need to be open for the endlessly welded track a certain target temperature can be brought, which is at about 21 to 23 ° C. These are the rails, usually at night, with so-called heat pipes subjected to a temperature elongation. This step, usually at finished laying on the thresholds, but not yet fortified or again dissolved new cheeks, can now elegantly into the described method are integrated when the rail car with Heat pipes for temperature elongation of the new rails is provided. The Neuschienen thus slide during their lowering in the area of Rail car through the heat pipes through, the temperature elongation takes place before laying the new rails on the thresholds, which in Meaning of the above-mentioned general objectives in such Rail laying work a fast, efficient, complete and cost effective Rail installation allows.

What now the attachment in the area of the rail car As far as the new rails are concerned, it is basically possible to be thought of as a work party behind the invention Run rail change train and with conventional fasteners, especially screwing machines, the new rails on the sleepers too Fasten. But also this step better in the overall system Being able to integrate is in an advantageous development of the invention provided that the rail change train also has an operating direction of travel arranged behind the guide means of the rail car Assembly unit for mounting the new rails on the thresholds comprises. These Assembly unit is basically the dismantling unit already described above similarly, i. In turn, it can be located immediately above the thresholds Work platform should include, and in particular on the rail supports of Swell include lowerable mounting devices.

The mounting unit can basically be at the rear end of the Rail car be mounted, such as in the form of a work platform with attached lowerable mounting devices. Appropriately, however the assembly unit on a in operating direction behind the Rail car exchangers arranged assembly cars be provided. This Mounting carriage corresponds in terms of its construction substantially the above described dismantling car. So again it can be provided that the assembly carriage a raised between its bogies frame and a work cage attached to the frame.

The rail shuttle according to the invention described so far thus expediently comprises a at its front end Transfer car, which directly to a drawn by a locomotive Neuschienen transport unit is coupled, behind a front Distance car, a dismantling car, the rail car, as well as in conclusion, i. in the direction of travel at the rear, the described assembly carriage. As has been described in detail, can with this invention Rail change train unloaded the new rails, in optimal bending line through Guided guide led to rail car and there directly to the Rail supports of the sleepers are discontinued, with the rails already through a welding system on the transfer car to a more or less "endless" tape were welded and when passing through the Heat pipes on rail car of a required temperature elongation were subjected. In the final assembly cart then the Final assembly of newly installed new rails on the sleepers.

As far as the removed old rails are concerned, they are added previously described Schienenwechselzug as well as the generic train through the expansion means on the rail change car from the rail supports removed and stored in particular next to the thresholds, so that they Do not obstruct the laying of new rails. Basically, these would have Old rails but then be collected in a separate work process. Order now also this collecting the old rails in the described Integrate work process can be in a particularly advantageous Further development of the rail shuttle according to the invention provided be that he also has an operating direction behind the assembly truck and in front of an old rail transport trolley arranged transfer car with Includes transfer means, which are designed to the removed old rails to pull on and push on the old rail transport vehicle. such Transfer cars with suitable transfer means are known in the art For example, as rail loading units "Robel" known and also in described above the DB textbook. It is particularly important here, too emphasize that similar to the automatic removal of the new rails of Neuschienen-Dolly with forward movement of the train also on automatic "pushing" of the old rails on the rear old rail transport vehicle he follows. It is important that at the beginning of the work the Front end of the old rail track to be removed from the rail support lifted, spread away and with the help of the transfer means of the transfer car so be widely used, that the old rails then at slower speed of Train be pushed automatically on the old rail transport vehicle.

If a reuse or refurbishment of the dismantled Old rails is intended, should also be with their loading on the old rail transport vehicle an optimum bending line is maintained, i. especially not too abrupt lifting the old rails from the expansion area under the Rail change car up to the transfer car done. This can be done at Rail change train according to the invention can be achieved in that it further one arranged between the assembly carriage and the transfer car rear distance carriage with guide means for lifting the over guide means includes old rails supplied by the rail change carriage. The function and The construction of this rear distance car corresponds to that of the above explained front distance car.

As well as in the front region of the invention Rail replacement with regard to the new rails, so are also in the rear Range with regard to the old rails turn different Management options can be realized: For example, it can be provided that the guide means of the rail car, the assembly truck and the rear distance car and the transfer means of the transfer car in such a way are aligned that the old rails when driving the rail shuttle on Rail car side spread apart to the mounting car guided around and on the rear distance car over his rear bogie be raised. This in turn offers the advantage that no old rails through Run through the assembly car, so that the staff working there undisturbed important assembly of new rails can make.

Alternatively, however, it is also conceivable that the guide means of Rail car, the assembly truck and the rear distance car and the transfer means of the transfer carriage are aligned such that the Old rails when driving the railcar on the assembly truck, rear Distance cars and transfer cars are each guided over the track center. This variant will in turn be considered if you have a Excessive spreading of old rails with a view to their reuse want to avoid and at the same time sufficient mounting space in the assembly truck is available.

In both cases can be advantageously provided that the Frame of the rear distance car between its front and rear Bogie a smaller width transverse to the operating direction than in the area of Has bogies, and that in the bottom of the rear distance car openings are provided for passing the old rails.

As already in connection with the front distance car described, is also noted at the rear distance car that, as a rule a relatively small load rests on it. From the above already described Therefore, reasons, the front bogie of the rear spacer car than be designed rear bogie of the assembly vehicle, and also the rear bogie of the rear distance car also by a single axle be replaced.

The old rails developed by the thresholds as well as the in the transfer car welded together Neuschienen one more or less "endless" band, which is due to the forward movement of the rail change train according to the invention by suitable guide means, in particular rolls, guided on the old rail dolly is pushed. Ultimately, however, the old rails as well as the new rails in individual Sections loaded side by side on the appropriate transport vehicle become. For this purpose, is conveniently on the transfer car a Separating device for separating the old rails, in particular sawing and / or Cutting torch, provided. With this, the endless band of old rails is opened the transfer car into individual segments with a length separated in the Essentially corresponds to the loading length on the old rail transport vehicle.

Again, a continuous slow ride of the To allow rail change train according to the invention and to avoid that to separate the old ribbon into individual sections of the entire train can stop, can be similar to that provided in the front train area Coupling device for coupling the new rails also provided here be that the separator on a longitudinal direction of the transfer car slidable carriage is arranged. For example, one on one Saw arranged first in the front area of the transfer car be arranged, and the old track belt passes through the saw. As soon as the maximum loading length on the old rail transport vehicle is reached, ie about a length of about 120 m, the saw is turned on and then sawn through the old track band, which takes a few seconds. During this time, the saw slide slides on the transfer car to the rear, so that the rail change train his forward drive can continue undisturbed. As soon as the old track band sawn, the saw is again "opened", i. the old track band can run through again undisturbed, and at the same time the saw carriage is back pushed to the front end of the transfer car.

Between a rail and the associated threshold, more precisely between the so-called rail foot base and the rail support becomes usually a so-called intermediate layer inserted. This was it formerly around a poplar wood, today one uses a thin plastic plate. At the Expansion of the old rails, it may happen that the used Liners stick to the removed old rails. Occasionally However, the liners can be reused, or they must anyway separated from the old rails with a view to their reuse become. This can be in an advantageous development of the invention Rail exchange train done by the that the old rails assigned Guiding means of the rail vehicle further mechanical scraper for Stripping of adhering to the old rails have intermediate layers. In these mechanical scrapers can be, for example, metal ribs or webs act, which are mounted in front of a roller pair forming a guide means and over which the dismantled old rail slides, in which case one at the bottom the old rail-sticking object "gets stuck" and is thus removed.

As explained above, the invention avoids Rail change train the problem occurring in the prior art that heavy Vehicles, in particular the locomotive and the fully laden Neuschienen-Dolly, have to drive over unpaved tracks. Also a possibly behind the according to the invention rail exchange trailer attached old rail transport trolley, which can achieve the same total weight drives at proposed system over fixed rails, namely in the area of Mounting car fastened new rails. However, they are also so far Some bogies inevitably discussed unsecured rails to lead, namely the rear bogie of the dismantling car, the Bogies of the rail car and the front bogie of the Montagewagen, according to all bogies between the Disassembly area and the mounting area. So now for the very unlikely case of a tipping over of the rail under such little loaded bogie will take a safety measure proposed that the rear in operating direction bogie of Dismantling car, the bogies of the rail car and / or the front bogie of the assembly truck with an emergency rerouting device is / are, which is designed to the respective car in the area of this If necessary, push off the bogie from the ground and to the side offset. This emergency rerouting device can in particular be telescopic extendable and / or pivotable supports, preferably are mechanically and / or hydraulically actuated. Should thus, for example, under the rear bogie of the dismantling the no longer fastened Tip old rail so that this bogie rests on the sleepers, so The supports of the emergency rerouting device can be pivoted and extended until they rest on the ground and on further extension the Lift the dismounting carriage in the rear area. The overturned old rail can then manually set up again, and the dismantling truck with this Bogie by retracting the emergency rerouting device on the erected old rail are set.

Behind the transfer car 16 follows as the next part of Rail exchange 10 of the invention a front spacer car 20. Wie one recognizes in the side view of Fig. 1 a, has the front shown here Distance car 20 at its front end, on which usually loads little load, only a single axis 22. The rear end of the front spacer car 20 however, is rotatably mounted on a front bogie 24 of a subsequent disassembly carriage 26 according to the invention.

As can be seen in the plan view of FIG. 1 b well, has the front spacer cars 20 via a so-called "narrow frame" 20a, i. its frame has between its front single axis 22 and the rear Bogie 24 a smaller width transverse to the operating direction of travel (arrow P) as at his ends up. Thus, it can be seen in the plan view of Fig. 1 b that the Frame 20a of the front spacer car 20 according to the invention at least in its middle area is narrower than any other vehicle frame. It was However, at this point it should be noted that other cars, in particular following in the operating direction of the dismantling 26 cars Rail car 28, a narrow frame may have.

It can be seen in Figs. 1 a and 1b immediately that the on the Rail car 28 following rear part of the invention Rail shuttle 10 substantially symmetrical to its front part is designed. So follows on the rail car 28 initially a Assembly cart 30 for mounting the installed new rails 14 and a rear Distance car 32, the front end turn on the rear bogie 24 of the assembly carriage 30 rests, which thus virtually a common bogie 24 forms for these two vehicles, which is in the operating direction rear end of the rear spacer car 32 in turn by means of a single axis 22 supported on the rails. It is understood, however, that the rear Distance cars 32 as well as the front distance car 20 as a completely independent car with two own bogies 24 or single axles can be trained. Likewise, one of the two distance cars 20, 32 as stand-alone car with two bogies 24 be designed, each other cars then in the manner shown here in Fig. 1 with a Single axis 22.

It can be seen in the plan view of Fig. 1 b turn the narrow Frame 32a of the rear spacer car 32. It is understood that the frame 20a, 32a of the two distance cars 20, 32 can be designed differently, for example, a "normal" as well as a narrow frame.

On the rear distance car 32 follows as the last vehicle of the Rail exchange 10 according to the invention a transfer carriage 34 for Handing over the old rails 36 removed and transporting them to the behind the rail shuttle 10 arranged old rail transport car 38th On the transfer car 34, a separating device 40 is schematically indicated, which in particular is a saw or a cutting torch or else a combination of these devices can act, and which serves as the Endless belt removed old rails 36 back into individual rail pieces according to the usable loading length of the old rail transport carriage 38 separate. Is used as the old rail trolley 38 a usual Long rail unit, as used as Neuschienen-transport vehicle 12 is, it is understood that the old rail endless belt 36 using the Separator 40 will cut on the transfer car 34 into pieces, the are about the same length as those on the new-rail dolly 12th 14. Depending on what is with the removed old rails 36 should happen, but it goes without saying for example, also possible, they clearly with the help of the separator 40 in to split shorter pieces.

After this purely constructive explanation of the structure of Rail change train 10 according to the invention will be described below with reference to FIG. 2 an example of Neuschienen- and old rail guide when rail changes with Help the rail change train 10 of the invention will be explained. Out For reasons of clarity of drawing, some vehicle superstructures in FIG. 2b has been omitted.

Fig. 2 shows an example of the Neuschienen- and the old rail course during the continuous operation of the invention Rail shuttle 10, i. after the conclusion of the first to be explained Einfädelphase. This threading is done as follows: First decided from which track position the old rails 36 removed and through New rails 14 are to be replaced, which is essentially due to the wear of the Old rails 36 depends. At this position, the thresholds 42 severed mounted old rails. The rail change train according to the invention then goes so far into the construction site that the rail car 28 on This separation between the end of the lying and the beginning of the to be built old rails 36 is. In contrast to the prior art Here, both the locomotive and the heavily loaded Neuschienen-transport vehicle 12 still drive on paved old rails 36. The same applies to the transfer trolley 16, the front distance car 20 and the direction of travel first bogie 24 of the dismantling carriage 26. Only in the area of this Disassembly carriage 26, the disassembly of the old rail fasteners in Shape of screws and clamps. This will be particularly hereafter be explained in more detail with reference to FIG. 7. So first, only the back Bogie 24 of the dismantling carriage 26 and the front bogie 24 of the Rail car 28 on unpaved old rails 36 drive what in the Usually uncritical, since these cars are usually not heavily loaded.

In the Einfädelphase the rail change train according to the invention then stopped first, as soon as the rail car 28 on the Separation point between the lying and the old rails to be removed 36 stands. With the help of conventional and not shown in the figures expansion means, especially small crane arms, hydraulic presses, etc., then become the this separation point adjacent ends of the old rails to be removed 36 to rear axle of the front bogie 24 weggespreizt to the on the Rail supports on the sleepers 42 Space for the now to be threaded New rails 14 to create. It is understood that for this reason the Old rails 36 are weggespreizt over as large a distance as possible, i. to Possibility of the entire old rail section from the separation point to the front Bogie 24 of the rail car 28, which is still on the subsequently to be removed old rails 36 is.

After thus under the rail car 28, the Rail support on the thresholds 42 have been exposed over several meters, the first new rails 14 are threaded. It will be in the further Description assumed that these are long rails 14 with a length of 120 m and more, on the Neuschienen-dolly 12 are charged, as shown in Fig. 3.

For threading a first pair of new rails 14 in particular with the help of a provided on the front distance car 20 winch system 21 from the new rail transport vehicle 12 via the transfer trolley 16 subtracted and, if necessary, with manual assistance until now exposed End of the remaining old rails under the rail car 28 moved on and docked there. The entire course of the deducted Neuschienen 14 from Neuschienen-Dolly 12 to the Rail supports under the rail car 28 is through Guide means 44 defined and should become a so-called "optimal bending line" lead the new rails 14. These guide means 44 are in Essentially about simple rollers or rollers over which the new rails 14 run, or even roller or roller pairs, between which the new rails 14th pass.

As soon as the beginning of the Neuschiene to be laid 14 at the free end is coupled to the remaining old rail, leads a slow Forward movement of the rail change train 10 according to the invention in the the arrow P in Fig. 2 indicated operating direction to an automatic Taking off the new rail 14 from its dolly 12. Looking at the in Fig. 2 illustrated "earthproof" reference system, it can be seen that the Neuschiene 14 here almost no horizontal movement, but only one Lowering movement of the new rail dolly 12 down to the Rail support performs, with this downward movement through the Forward movement of the rail shuttle 10 and its guide 44th is enforced.

On the first few meters of this forward movement you thread now the initially weggespreizten ends of the old rails to be removed 36 in Guide means 44 of the rear Zugbereichs a. Since these weggespreizten ends the rear portion of a farther still firmly mounted on the thresholds 42 Altschienenabschnitts represent, this rear extended area of the Old rails 36 at slow forward travel of the rail shuttle 10 in the in Fig. 2a shown manner raised and up to the rear old rail dolly 38 pushed. It is understood that in the earth Viewing system of Fig. 2a and the removed old rails 36 almost perform no horizontal movement, but with forward movement of the Rail change train 10 due to the positive guidance by the guide means 44th lifted from the rail supports to the old rail transport carriage 38 become. In other words, the slow-moving "peels" Rail change train 10 after successful threading the strand of old rails 36 slowly out of the rail supports and pushes them to the rear Old rail trolley 38.

Figs. 2a and 2b, as already explained, now the continuous Operating state of rail shuttle 10 after successful completion of Einfädelphase is: The entire train 10 moves slowly in Fig. 2 to the right (arrow P). Here, new rails 14 are deducted from their trolley 12, forced by the guide means 44 such that they under the Rail car 28 are placed on the rail support, after which they are mounted in the area of the assembly vehicle 30 by personnel working in it become. Thus, therefore, the rear bogie 24 of the rail car 28 the first bogie that runs over the "freshly laid" new rails 14. All further forward bogies 24 still drive on the immediately thereafter in the area of the rail car 28 28 old rails 36. The actual disassembly of the old rail fasteners takes place only in the area of the dismantling 26 by there operating staff, so that the more forward located parts of the rail shuttle 10 and the Neuschienen-transport vehicle 12 and not shown in the figures locomotive over attached old rails 36 can drive, which according to the invention the accident risk considerably minimized.

In the plan view of Fig. 2b shows a possibility of New rail and old rail guidance during the rail change:

The guide means 44 of the entire railcar 10, in particular over the entire train 10 distributed rollers and pairs of rollers, spread the new rails 14 removed from the new rail transport vehicle 12 already in the area of the takeover wagon 16 and they continue to spread in the area of the front spacer car 20. It can be seen in the plan view of Fig. 2b now also the advantage of the proposed for the front transfer car 20 narrow frame 20a, namely, which allows the new rails 14 in Lowering the area of the front distance car 20: As can be seen in particular from the comparison of the side view in Fig. 2a with the top view in Fig. 2b clearly yields, the new rails 14 are at the front end of the front Distance car 20 still above the normal frame level of all vehicles, i.e. the frame height of the vehicles in the area of their bogies 24. Between the front and the rear end of the front spacer car 20 is the Reduction of the new rails 14 below this normal frame height. Would you instead of a narrow frame in the front spacer car 20 a frame use with the usual width, so the new rails 14 would have openings through the Floor of the front spacer car 20 are lowered. The one shown here Rail track finally allows the rails 14 completely around the Disassembly 26 lead around, as can be seen in Fig. 2b. This Rail track has the advantage that the active in the demountable 26 Personnel the old rail fasteners on the thresholds 42 undisturbed dismantle, without this on the lowered in this area Neuschienen 14 to pay attention. The risk of possible injuries will thereby reduced.

In the area of the rail car 28, the guide means 44 in turn arranged so that the new rails 14 just before the rear Bogie 24 of the rail car 28 the rail support on the Reach thresholds 42 and can be discontinued there.

In Fig. 2b can be seen further to the Neuschienen-course largely symmetrical old rail course: The developed old rails 36 are in the Area of the front bogie 24 of the rail car 28 from the Rail supports lifted by the guide means 44 to the Assembly cart 30 guided around and finally in the area of the rear Distance car 32 and the transfer car 34 so far merged again that they pushed onto the final old rail trolley 38 can be. One recognizes here again the advantage of a narrow one Frame 32 a at the rear distance car 32, between the front Bogie 24 and its rear single axis 22, the old rails 36 the normal frame level "pierced". The shown old rails course offers the Advantage that the staff working in the assembly vehicle 30 is fully on the assembly the newly laid new rails 14, i. the attachment of Neuschienen 14 means Screws and clamps on the sleepers 42, can concentrate, and that Risk of injury from passing old rails 36 is excluded. It is again emphasized that the old rails 36 and also the new rails 14 only in the reference frame of the railcar 10 itself almost horizontal pass by, in the earth-fixed reference system, however, perform the rails exclusively an up and down movement, and the train moves in the figures of from left to right.

After these overview representations of FIGS. 1 and 2 will now be Below with reference to FIGS. 3 to 9 details of the invention Rail change train 10 will be explained:

First, Fig. 3 shows a greatly simplified rear view, i. a View from the front end of the transfer trolley 16 in the direction of travel to front, on the Neuschienen-Dolly 12, the front of the invention Train 10 is coupled. The Neuschienen-Dolly 12 includes in Essentially a horizontal frame 12a, which has one at its bottom mounted suspension device with a bogie 24 or - as in Fig. 3 from For reasons of simplicity - a simple axis 22 in the usual way connected is. The wheels 46 run on still laid and fastened old rails 36, which are fastened in the region of the rail supports on the sleepers 42. On Neuschienen 14 are charged to the frame 12a, in the example of FIG. 3 in two Layers on top of each other.

In the lower part of Fig. 3 is by a dashed line the Vehicle boundary profile F drawn, i. the area around the track around, no part of a passing train in transport position may protrude. The meaning of this vehicle boundary profile F will continue below in connection with the possible use of a narrow frame be explained for the rail car 28.

The charged on the Neuschienen-Dolly 12 Neuschienen 14, as explained above, by a cable winch 21 in Front area of the front distance car 20 from the new bus dolly 12 and deducted via the transfer car 16. At a usual length of a wagon (from buffer to buffer) of 21.5 m this means that seen in the operating direction rear end of a new rail 14 of about 120 m in length already under the rail car 28 on the local Rail support deposed and to the remaining old rail end can be coupled, while seen in the direction of travel front end of this Neuschiene 14 still rests on the Neuschienen-transport vehicle 12. The through the guide means 44 of the rail shuttle 10 forced curve of the Neuschiene 14 should then correspond to the so-called "optimal bending line", i.e. the course with the lowest possible rail voltages. At slower Forward drive of the rail shuttle 10, this new rail 14 moves automatically from the Neuschienen-transport vehicle 12, so that in Fig. 4th indicated cable winch 21 already can be used to to seize another pair of rails on the Neuschienen-Dolly 12 and via the transfer trolley 16 in the direction of the front spacer car 20 too pull. This is done in such a way that the rear seen in the direction of travel, ie soon to be lowered end of this next pair of rails to those in Fig. 4th shown welding system 18 is pulled on the transfer trolley 16. More accurate said each rail 14 of the next Neuschienenpaars so far used that in the direction of travel rear end in the area of a Welding head 19 of the welding system 18 is located. Once the front in the direction of travel Ends of the two currently withdrawn through the welding system 18 therethrough Neuschienen 14 in the area of these welding heads 19 are, is currently withdrawn Neuschienenpaar 14 with the next deducted Neuschienenpaar 14 welded by means of the welding heads 19, preferably in Shape of a flash butt weld known in this field. To while This welding lasting a few minutes does not or only to the extent possible to have to stop briefly, at least the welding heads 19 are on a carriage 17 movable in the longitudinal direction of the transfer trolley 16. This carriage 17 should be traversable on the transfer trolley 16 a few meters, so he during the welding in Fig. 4 from right to left on the Transfer car 16 can be moved, in such a way that the slow forward travel of the train 10 (in Fig. 4 turn to the right) balanced becomes. Once the currently withdrawn Neuschienenpaar 14 and as next Neuschienenpaar 14 to be deducted in the welding heads 19 together may have been welded, another may be deducted soon Neuschienenpaar be attached to the winch.

It can be seen in the side view of Fig. 4a and the plan view of FIG. 4b also in the front region of the front spacer car 20, immediately behind the cable winches 21, two rollers as a guide means 44 for the withdrawn Neuschienenstrang.

The further course of the withdrawn Neuschienenstrangs is in the 5a and 5b shown as a side view and top view, respectively:

Between the front single axle 22 and the rear bogie 24 of the front spacer car 20, the new rails 14 through the normal Lowered frame level, which is facilitated by the fact that the Frame 20a is designed as a narrow frame. Thus, the new rails run 14 under a work booth 48 mounted on the bogie 24, that the front spacer car 20 and the dismantling 26 share.

In the area of the dismantling carriage 26, the new rails 14, as can be clearly seen, in particular in the plan view of Fig. 5b, far outside the area of the old rails 36 still fastened on the sleepers 42 passed, on which the dismantling 26 drives and for reasons of Graphical clarity in Fig. 5b drawn only to below the work booth 48 are, but of course from there continue to the right. The leadership of New rails 14 in the area of the dismantling carriage 26 takes place again via Guide means 44 in the form of rollers suspended on longitudinal profiles 50, which in turn on the raised frame 26 a of the dismantling carriage 26th are mounted at about the normal frame level. This will be will be discussed in more detail below in connection with FIGS. 6 and 7.

Fig. 6 shows a partially sectioned rear view of the disassembly carriage 26 according to the invention, wherein the section approximately in the rear Area of the front bogie 24 is made (section along the line VI-VI in Fig. 5a). One recognizes the frame 26a of the dismantling carriage 26, which has a Trunnion 52 is supported on the front bogie 24. The frame 26a is in this range at the level of the normal frame level, i. for example, in approximately the same height as the frame 16 a of Transfer carriage 16, the frame 12a of the new rail transport vehicle 12th etc. (see Fig. 1a).

In the front region of the dismantling carriage 26 is on the frame 26 a a work booth 48 arranged for the staff working in the dismantling 26. It can be seen in Fig. 6 in the middle of a leading into the work cabin door 48 and side windows. It can also be seen in Fig. 6 left and right outside of the frame 26a suspended guide means holders 45, in their lower in Fig. 6 Each area a roller 44 as a guide means for the pair of new rails hold.

As mentioned above, Fig. 6 is a view in the direction of travel of Rail change train 10. The in Fig. 6 left and right on the respective Rolls 44 current Neuschienen 14 thus run in the reference system of the train 10 the viewer and are hereby lowered continuously, then behind the viewer, namely in the area of the rail car 28, again spread apart on the rail supports to be discontinued.

Fig. 7 shows a highly simplified schematic cross-sectional view similar to Fig. 6, but with the cut through the dismantling something is further back, so here by the raised area of the Frame 26 a has been cut, namely along the section line VII-VII in Fig. 5a.

It can be seen in Fig. 7 two in the longitudinal direction of the dismantling carriage 26th extending and fastened at the bottom of its raised frame 26 a Longitudinal member 54. Purely by way of example only on the left side member 54 shown a roller holder 56 shown with a spring suspension 58, on whose lower end of an electric screwdriver 60 is suspended in the in Fig. 7 just shown by a worker 62 to unscrew a Threshold screw is used. The roller holder 56 allows the Displacement of the electric screwdriver 60 along the longitudinal member 54 in The longitudinal direction of the dismantling carriage 26. Thus, the entire Rail change train 10 and thus the dismantling 26 continuously in Driving the operating direction forward, i. in the illustration of FIG. 7 from Viewer away, and yet the worker 62 the electric screwdriver 60 so long as necessary, usually a few seconds, to a certain Put on the sleeper screw to release it. During this time, during the entire train moves forward, the roller holder 56 rolls on the longitudinal member 54th towards the rear, as it were in Fig. 7 towards the viewer.

It is understood that also on the right in Fig. 7 shown Longitudinal member 54 a corresponding arrangement of a roller holder 56, a spring suspension 58 and an electric screwdriver 60 may be provided which is operated by another worker 62, at the same time the Disassemble fasteners of the right-hand side rail. These elements are However, for clarity in Fig. 7 has been omitted to under Others represented by the right wheel 46, the position of the other System components relative to the bogies 24 to illustrate.

It can also be seen in Fig. 7 left and right below the raised frame 26a turn the longitudinal profiles 50, which in turn in each case a guide means holder 45 is attached, which is a roller 44 as Guide means for the left and right Neuschiene 14 holds. Comparing the Position and height of the illustrated in the sectional view of Fig. 7 Neuschiene 14 with that of FIG. 6, so one made further forward in the direction of travel Section view, it is found according to the above explanations that the left and right new rail 14 between the sectional plane of Fig. 6 and in Moving direction behind underlying cutting plane of Fig. 7 lowered down and was simultaneously spread outward, according to the in Fig. 5b in plan view shown course of the two new rails 14 in the disassembly carriage 26th

It is understood that numerous details in the very schematic Views of Figs. 6 and 7 have been omitted. Such is the case Dismantling 26 generally, and in particular at his work booth 48 to fully equipped workplaces with suitable lighting, windows, Access stairs, if necessary surveillance cameras and monitors etc.

The further course of Neuschienen 14 towards Schienenauflager is now shown in Figs. 8a and 8b. One recognizes first in the side view Fig. 8a right, the rear end of the dismantling carriage 26 on which a Iron collecting device 64 is mounted, which is a substantially The iron collecting container 66 comprises, in the small iron, e.g. dismantled Threshold screws and tension clamps conveyed via a conveyor belt 68 on which these pieces of hardware from a just above the thresholds 42 driving magnetic drum 70 are thrown.

In Fig. 8 is shown centrally the rail car 28 with a elevated frame 28a, in the middle of two working seats 72 are suspended. Of the The purpose of these working seats 72 is described below in particular with reference to Top view in Fig. 8b are explained:

As mentioned above, rails are usually not directly, but on so-called intermediate layers on the thresholds 42. These Liners are usually changed when changing rails. In the shown in Fig. 8 Neuschienen- and Altschienenführungsvariante, the in Fig. 2 corresponds explained variant, is approximately the middle of the rail car 28 the area at which a seated on a seat 72 worker 62 on undisturbed on the sleepers 42 down, an old liner lose weight and put on a new liner. As can be seen in Fig. 8b Immediately sees, is at any other longitudinal position of the rail car 28 either from the front coming pair of Neuschienen 14 or after behind withdrawn pair of removed old rails 36 closer to the track axis located in Fig. 8b in the middle of the rail car 28 by a dash-dotted line is indicated.

In the operating direction behind the working seats 72 can be seen in Fig. 8 a pair of heat pipes 74, which by means of a holder on Rail car frame 28a are suspended. One recognizes clearly that the new rails 14 immediately before placing on the rail support the thresholds 42, i. in Fig. 8a and Fig. 8b immediately before, that is to the right of rear bogie 24 of the rail car 28, through this Run through heat pipes 74. In these heat pipes 74 is the prescribed temperature elongation of the Neuschienen to be laid 14, by you bring them to a well-defined target temperature. In Central Europe usually at night at cooler temperatures, so that the heat pipes - as the name implies - are used as heating elements. Basically but it is also conceivable to replace the heat pipes with cooling elements, then For example, in the summer during the day defined target temperatures of the new rails 14 to reach.

In the side view of Fig. 8a can be seen on the Rail car 28 a roof 28b. Thus, for example Gas cylinders, in particular propane cylinders 76 for supplying energy to the Heat pipes 74 are stored safely. Furthermore, it can be seen in Fig. 8a in the area the working seats 72 container 78, in particular for collected old Liners and new liners to be laid, as well as for iron and steel Bracing elements.

It can be seen in Fig. 8 behind the rail change car 28 the front part of the assembly vehicle 30, in turn - as well as the Disassembly 26 - in this by no means limiting example having raised frame 30a. In the front area of the assembly truck 30, even before its bogie 24, is an emergency rerouting device 80 schematically indicated, the two preferably hydraulically extendable and retractable supports 82 comprises. Should now indeed the unlikely event occur that one of the unattached rails in the area of Fig. 8 tilts, So either the not yet developed old rail 36, on the example, the front bogie 24 of the rail car 28 is, or indeed already built, but not yet attached Neuschiene 14, on the example of the rear bogie of rail car 28 stands, so can with the help of this Supports 82 of the assembly cars 30 are "jacked up" and one below it overturned Neuschiene 14 be erected again. It is understood that in the Area of all bogies 24 of the rail shuttle 10, which basically over Unmounted rails, such emergency rerouting devices 80 may be provided in the accompanying drawings only for reasons the clarity are not all shown. This concerns, as explained above, the illustrated in Fig. 8 four bogies from the rear bogie of Dismantling carriage 26 to the front bogie of the assembly vehicle 30th

FIG. 9 shows a sectional view of the rail vehicle 280 opposite to the direction of travel of the train, the section along the in Fig. 8b dash-dotted line IX-IX was performed. This view So corresponds to a view from the front of the rail car 28 to the rear, in other words, the one shown in Fig. 9 moves Rail car 28 when driving the rail shuttle 10 on the Viewer too. One recognizes first approximately in the middle of the Railcar horizontal the frame 28a, where the two already in Associated with Fig. 8 discussed working seats 72 are suspended. On the in Fig. 9 left working seat 72 sits a worker 62, who from this position easily on the rail supports on the thresholds 42 reach down and the Interchangeable layers can replace. To this liner changes quickly to perform, the construction shown in Fig. 9, in which on the frame 28a another job for another worker 62 is arranged, further on the frame 28 a further container 78 for new laying and old exchanged intermediate layers are provided. The in Fig. 9 upper worker 62 may have new liners working under him Send colleagues over a slide 84. At this slide can at the same time be hung a circulating conveyor on which the lower Worker 62 places the exchanged liners, so that they are the above fed to working colleagues and placed by him in one of the container 78 can.

To explain the positions of the different rails in this Area in Fig. 9, the following old or new rails are schematic drawn:

Immediately in the area of the right (in the front view of FIG. 9 thus left to see) hand of the lower worker 62 are two rail sections one above the other, with the upper rail already being one removed and slightly raised end rail 36 is and in the immediately below it in the section drawn rail to the front upcoming Neuschiene 14, which has not quite reached the rail support. The same applies to the two in cross section on top of each other mirror-symmetrical position on the right in Fig. 9 indicated rails.

It can also be seen in Fig. 9 left schematically indicated a Guide means holder 45 with a guide roller 44, which is strictly speaking not in the sectional plane shown in Fig. 9, but in the direction of travel of the train 10 behind it (approximately in the area of the rear bogie 24 of Rail car 28). The drawn, running on the roll 44 Rail is thus the already discussed old rail 36, in this further back plane on the one hand lifted up and on the other was spread away to the left, as in the two views of FIG. 8 clearly illustrated and symbolized in Fig. 9 by the arrow AS.

Similarly, it can be seen in Fig. 9 right schematically indicated another guide means holder 45 with a guide roller 44. These too In fact, the arrangement is not in the sectional plane according to FIG. 9, but in the direction of travel of the train 10 in front, i. closer to the viewer of FIG. 9 (substantially in the area of the front bogie 24 of the Rail car 28). Namely, the rail running on this roller 44 is a new rail 14 brought up from the front draw area, between this further forward plane and the actually shown in Fig. 9 Cutting plane is lowered and further inward, as is also the case clearly shows from the two views of FIG. 8 and in Fig. 9 by the arrow NS is symbolized.

It can be clearly seen from these rail diagrams that the Sectioning plane IX-IX approximately through the middle of the rail car 28 the one Level is the optimal access of the lower worker 62 to the Liners allowed. Would you continue the work seats 72 in the direction of travel Mount the front, so would the old rails 36 closer to the track axis and would hinder the liner change. On the other hand, if you have the working seats 72 in Direction mounted farther back, the new rails 14 are too close to the respective track axis and also hinder the liner change.

As can be seen from the above explanations to Interlayer change results, this is then optimally feasible if the Neuschienen 14 and the old rails 36 in the manner explained in Fig. 2 and Fig. 8 "crossed", i. each to the dismantling 26 and the Assembly carriage 30 are spread around. alternative Rail guide options are finally shown in Fig. 10 in plan view:

Fig. 10a shows first a variant in which the pair of new rails 14 as in the previously discussed embodiment to the dismantling 26th spread around to provide maximum space there, where the Neuschienen 14 then in the area of the rail car 28 inside be led to finally in front of the rear bogie 24 of the Rail car 28 in the track axis on the rail supports to be discontinued. In this respect, the Neuschienenführung corresponds to the date discussed course.

The old rails 36, however, are in this embodiment of FIG. 10a not spread outwards around the assembly carriage 30, but run there in the area of the track center. That in the assembly car 30, the otherwise in construction corresponds to the dismantling 26, active personnel must therefore on pay attention to passing through the assembly carriage 30 old rails 36.

In the further alternative according to FIG. 10b, the course of the Pair of old rails 36 of the initially discussed in detail "Crossover variant", but now the new rails 14 are not around the Dismantling carriage 26 spread around, but rather in the field of Track center from the new rail transport trolley 12 to the rail car 28 headed. The advantage of this Neuschienenführung is that the Bending line of the new rails 14 also without crossing and even gentler can, except for the vertical lowering of the new rails 14 no horizontal spread is required. This may be of interest if to the Rails special requirements to be made in later operation, such as at High-speed lines. The disadvantage of this variant is again in that the personnel working in the area of the demounting carriage 26 (see Fig. 7) by passing through the dismantling carriage 26 new rails 14th is disturbed. Of course, this problem can be solved by that the new rails 14 in the area of the dismantling carriage 26 by an am Frame 26a can run tightly mounted guide tube to at least one reduce possible risk of injury.

Finally, let me briefly mention the "Ausfädelprozess" at the end of the Rail replacement work received.

As explained above, during the continuous Use of the rail change train 10 according to the invention on the Transfer car 34 pushed old pairs of rails there through the Separator 40 "portioned" into appropriate parts, which then on the behind located old rail trolley 38 have space. If now the Rail change train reaches the end of that section of the track in which the Old rails 36 to be replaced by new rails 14, so the train runs 10th so far until the front bogie 24 of the rail car 28 on a Old rail section is, which should remain. The old rails 36 are then immediately behind the front bogie 24 of the rail car 28 separated, for example sawn through, as well as that of the front Zugbereich Arriving Neuschienenpaar seperated at a suitable place and attracts re-start the rail shuttle 10 automatically to the last remaining meters of rail supports on sleepers 42. In contrast However, this is missing now for the last few meters of the old rails 36 to be removed necessary back pressure, which they during continuous operation on the Old rail trolley 38 pushes, since the old rails 36 yes, as just explained, were already severed in the track. Because of this, are on the Transfer car 34 usually provided transfer means designed to are to use the old rails 36 removed and on the old rail transport vehicle 38 to push. These may be, in particular, crane arms or gantry cranes, as generally known in the art Area of collecting old rails known and in Fig. 1 as an arm on the Separator 40 are indicated schematically.

The rail change train according to the invention was in the figures on the basis of his preferred, but by no means restrictive Embodiment, explained in the behind the rail car 28 more cars for mounting the freshly laid Neuschienen 14 and the removed old rails 36 are coupled. It is, however, again to Remember that the rail change train 10 according to the invention in principle also without these components, as mounting in the area of Rail car 28 laid new rails 14 in principle also by a work troop running behind the train 10 can take place. Likewise the collection of the old rails 36 also by conventional rail loading units, about the "design Robel" done. Essential to the invention is namely, starting from the generic rail change train only the use of the described Dismantling unit, approximately in the form of detailed demounting carriage 26, behind the takeover wagon 16 and before the expansion of the Railcar 28 is arranged and thus the number of bogies 24, which have to drive over unpaved rails, considerably reduced.

Likewise, it is understood that numerous changes and Modifications to the rail change train according to the invention described 10 can be made. In particular, measures are to Increasing the so-called spread length, i. the distance between the rear bogie of the train 10, which still drives on old rails 36, and the think first bogie 24 of the train 10, the already on new rails 14th moves: In the embodiments described so far, these were the front and the rear bogie 24 of the rail car 28. The to be removed old rails 36 must be behind the front bogie 24 of the Rail car 28 at least in the preferred Rail guide variant according to Fig. 2b and Fig. 8b relatively quickly be spread outwards. Likewise, those arriving from the front must Neuschienen 14, which are still in the area of the front bogie 24 of Rail car 28 are outside its frame 28a, relatively strong inward, so that they are "on time" before the rear bogie 24 of the rail car 28 reaches the track axis have, possibly even passed through the heat pipes 74. These Spreader requirements can now be mitigated by using the above defined spread length increased by taking the entire Rail change carriage 28 in continuous operation of the train 10 lifts, for which one extends its front end with a drawbar, that on the rear End of the dismantling carriage 26 rests and can press up there, and wherein the rear end of the rail car 28 by means of a Extended drawbar, which rests on the front end of the assembly carriage 30 and can also push up there. Then the whole "floats" Rail car 28 during continuous driving, where he leaning on his neighbors 26, 30. The spread length is then no longer given by the two bogies 24 of the rail car 28, but rather by the distance between the rear bogie 24 of Dismantling carriage 26 and the front bogie 24 of the assembly vehicle 30th This gives you a few meters of spread and thus gentler Bending lines.

Especially in this case, it makes sense, as discussed above, also the rail car 28 with a narrow frame 28a provided so that the gutter of the system of rail car 28 and on him guided rails in tight curves remains low, especially the permissible vehicle limiting profile F (see Fig. 3) is maintained.

With regard to the explained spread length is also on another Variability of the rail change train 10 according to the invention to point out: The shorter the spread length defined above, the "stiffer" Behave in this spread on the Schienenauflager abzusetzenden Neuschienen 14. One can therefore in the area of the rail car 28 a Einfädelhydraulikvorrichtung provide, which is essentially two hydraulic Includes pressing. The rear hydraulic press, attached to the frame 28a of the Rail car 28 is mounted so that it directly above the Threshold 42 is located, presses only a few inches above the rail supports located portions of the incoming from the new Neuschienen 14 to the outside, so that they run parallel to the track axis. A little further ahead Hydraulic press generates a back pressure on the new rails 14 inwards. When an embodiment of the rail car 28 is used, the is provided with heat pipes 74, so should the front hydraulic device in Operating direction in front of the heat pipes 74 and the rear hydraulic device behind the heat pipes 74 are each attached to the frame 28a such that they by controlled extension of pistons on the passing Neuschienen 14th can press.
