    专利说明:

    The present invention relates to a rail vehicle for track superstructure renovation, with at least two chassis and between a work area in which the rail vehicle along the direction of succession a Ausfädeleinrichtung for old rails, a removal device for old sleepers, a ballast bed clearing device, a ballast bed applicator, a depositor for new sleepers and a threading device for new rails.
    A rail vehicle of this type is the track construction machine RU 800-S, which has been distributed by the applicant since 2005. After renewal of the ballast bed and the tracks in a section using this track-laying machine, the same section of road must be subjected to another two consecutive stuffing with a conventional tamping machine, u.zw. a first "construction site" plug after which the track can be negotiated at low speed and a subsequent "finalization plug" to align the track and finalize its ballast, thus the track for normal driving at high speed can be released.
    The invention has for its object to provide an improved rail vehicle for track superstructure renovation, which simplifies and speeds up these operations.
    This object is achieved with a railway vehicle of the aforementioned kind, which according to the invention is characterized in that the ballast bed applying means comprises in sequence: a first ballast applying means for applying a first ballast layer, a compacting means for compacting the first ballast layer, and a second ballast applying means for Applying a second layer of gravel.
    The two-step application of the ballast bed with intermediate compression of the lower ballast layer achieves a pre-compacted ballast bed which can completely eliminate the need for a second stuffing operation in the post-processing. As a result, the track renewal can be completed earlier and the route can be re-run faster.
    For this purpose, it is particularly advantageous if the rail vehicle additionally contains a tamping unit arranged downstream of the threading device, preferably a combined track lifting, straightening and tamping unit. In combination with the two-layer application of the ballast bed and pre-compression of the lower ballast bed layer can thus in one operation, with the same machine, such a high stabilization of the track bed and the track can be achieved that the track after editing with the rail vehicle according to the invention already directly for a driving operation in a medium speed range up to 70 km / h can be released. The subsequent single required finalization stuffing operation may then be performed at a later time in a conventional manner with a tamping machine to finalize the line for high speeds.
    In a first preferred embodiment, said compacting device is a vibrating aggregate, for example a vibrating plate. Alternatively or additionally, the compression device may be formed by at least one conveyor screw arranged in the first ballast application device, which enables a particularly noise-conserving operation in comparison with a vibration plate.
    A further preferred embodiment of the invention is characterized in that at least one of the ballast application devices is designed to apply its ballast layer with a wedge-shaped cross section. As a result, the required in a track curve cant of the track outer strand relative to the inner strand can be miterzeugert same. In conjunction with the pre-compaction of the lower ballast bed layer and the optionally integrated plug, it is thus possible in a single operation, i. be rehabilitated with a single crossing with the rail vehicle according to the invention, even curvy sections. In contrast, a rehabilitation of such curvy Steckenabschnitte with conventional track construction machines initially requires a reduction of the track cant with the help of a track tamping machine in a pre-ordained operation, then the rehabilitation of the horizontally leveled track, i. the replacement of the ballast bed and the track, with the track-laying machine, and then a new operation with the tamping machine to rebuild the track cant. All this is reduced with the rail vehicle of the invention to a single operation.
    For this purpose, at least one of the ballast application devices preferably includes a transverse conveyor for supporting the ballast base increased ballast discharge. Since in a track cant the rail vehicle is inclined towards the inner strand, whereas just on the side of the outer strand to be increased ballast is required, can be counteracted with such a transverse conveyor of the gravity effect of the rail vehicle inclination.
    According to a further preferred feature, it can be provided that the ballast bed clearing device dips into the subgrade below the ballast bed in order to remove it in a wedge-shaped manner. This can be a banked slope of the drainage can be achieved, possibly even opposite to the surface slope of a wedge-shaped ballast bed for the track cant in bows.
    In a further preferred embodiment of the invention, a unwinding device for a geotextile is arranged between the compacting device and the second ballast application device. This achieves additional stabilization of the ballast bed. The geotextile can also serve as a filter layer between the upper and lower gravel layer to prevent the entry of small material and undersize into the compacted lower ballast bed layer, which could affect their cohesion.
    The rail vehicle of the invention may be further equipped with an integrated ironing release device, which is disposed upstream of the old rail Ausfädeleinrichtung. So far, the iron, with which the old rails are attached to the sleepers, such as screws, nuts, bolts, clamps, springs or the like, had to be removed by hand in a separate operation. The machine according to the invention integrates an automatic ironing-release device, which does this automatically during the track construction. The small-iron release device, for example, by sawing, cutting, flame cutting, water jet cutting, laser cutting, drilling, hammering, etc. disassemble, loosen or separate the iron, and then remove the same residues automatically, for example by means of a magnetic conveyor belt.
    Following the Neuschienen-Einfädeleinrichtung the rail vehicle can also be an automatic ironing
    Attachment device included, for example, an automatic screw, Verbolz- or stapler.
    In a further advantageous embodiment, an air-conditioning device for preheating and / or cooling the new rails is provided in the area of the new-rail threading device. As a result, the rails can be introduced the same with the correct bias and need not be drawn in a separate step for the subsequent welding process.
    In a variant of the invention, the ballast bed clearing device can be designed to also clear the edges of the ballast bed lying outside the track, optionally together with deposits on the edge path of the track. This eliminates a separate clearing and refilling the ballast bed edges, as is the case with track laying machines according to the prior art. In particular, this also avoids that center already applied new ballast partially removed again at the edge, processed and fed again as flank gravel. The burden on the ballast processing plant of the machine is thereby reduced.
    If the entire ballast bed, ie including the ballast bed edges, is cleared, a further unwinding device for unrolling another geotextile can optionally be arranged between the ballast bed clearing device and the ballast bed application device. This additional geotextile can cover the entire length of the ballast bed
    Extend width of the subgrade and build an additional stabilization and screening effect between gravel bed and planum.
    The ballast bed clearing device may be formed by conventional Räumketten or beads. It is particularly favorable, however, if the ballast bed clearing device is formed by a pair of counter-rotating, one-sided conveyor screws. Thus, a much quieter operation can be achieved than with Räumketten, which have numerous noisy metal-to-metal sliding surfaces. A particularly quiet operation is achieved when the augers transport on a downstream plastic conveyor belt.
    If not just the entire ballast bed along with the flanks clearing gravel bed clearing device is used, but such a ballast clearing device that clears only the gravel directly below the track, the rail vehicle according to the invention on each track side a ballast bed side sweeper with downstream Schot terbettflanken On. Also, the ballast bed flank broaches can be formed either by conventional Räumketten or -raupen or preferably by one or two opposing, one-sided conveyor screw (s) to achieve a low-noise operation. Here, too, the screw conveyors can convey on a downstream plastic conveyor belt for further noise reduction.
    Preferably, a drive bead is provided between the Ausfädeleinrichtung and the removal device and / or at least one support skis between the depositing device and the threading device. This ensures a stable position and safe propulsion even over a long working area.
    According to a further preferred feature of the invention, the ballast bed clearing device re-cyclizes its overburden via conveyor belts and a screen into the first and second ballast bed applicators. By recycling the ballast bed, a considerable saving in overburden waste and new material to be purchased can be achieved.
    The invention will be explained in more detail with reference to embodiments illustrated in the accompanying drawings. In the drawings: Figures 1a to 1c show the rail vehicle of the invention in operation in a schematic side view;

    In FIGS. 1 a to 1 c, a rail vehicle 1 for the rehabilitation of a track superstructure 2 is shown. The track superstructure 2 comprises according to FIG. 3a a ballast bed 3, on (or partially in) which is a track 4 of sleepers 5, rails 6 and iron. The track superstructure 2 rests on a track substructure 7, the so-called "planum", of compacted subsoil (ground). The rehabilitation of the track superstructure 2 comprises an exchange of the ballast bed 3 and the track 4, i. a replacement of the old ballast 3 ', the old sleepers 5' and the old rails 6 'by Neuschotter 3 ", Neuschwellen 5" and Neuschienen 6 ".
    The rail vehicle 1 usually consists of several cars coupled to a train (although this is not mandatory) and the components of the rail vehicle 1 shown in Figures 1a to 1c are distributed to different cars according to their respective space and weight requirements. Fig. 1 shows an exemplary car division of the rail vehicle 1 in a central carriage 8 with three chassis 8 ', 8 ", 8' '', wherein the carriage 8 at the location of the middle chassis 8" optionally may have a joint 9. At the central carriage 8 are seen in the direction of travel F front one or more trolleys 10, 11 coupled to the deposit of old sleepers 5 'and for storing Neuschwellen 5 "The cars 10, 11 are with corresponding movable gantry cranes 12 for manipulating the old and Neuschwellen 5 ', 5 "equipped, in particular to the Neuschwellen 5" from the trolley 11 to put on a carriage 8 leading conveyor belt 13 and lift off the old sleepers 5' of a laxative carriage 8 transport belt 14 and store on the trolley 10.
    In the direction of travel F back are at the central car 8 one (or more) cars 15 for the recycling of old ballast 3 'from the ballast bed 3 to Neuschotter 3 "and coupled to the supply and supply of Neuschotter 3". The car or wagons 15 contain for this purpose one or more high-performance sieves 16, to which the old ballast 3 'is fed by the carriage 8 via conveyor belts 17, 18 and which therefrom sift off upper and lower grain and discharge into a overburden container 19. The remaining, correctly sieved old ballast 3 'is the high-performance sieve 16 as Neuschotter 3 "via conveyor belts 20, 21 fed back to the central car 8, optionally together with fresh, non-recycled Neuschotter 3" from one or more silo units 22nd
    It is understood that the rail vehicle 1 may have other carriages (not shown), such as locomotives, hydraulic units for driving the various devices of the rail vehicle 1, etc. Also, the conveyor belts 17, 18, 20, 21 shown are shown only by way of example and in part; It is understood that these may be subdivided into a plurality of successive conveyor belt sections, in particular at the articulation and coupling points of the carriages 8, 10, 11, 15, as known in the art.
    The individual components of the rail vehicle 1 are now described in the direction of travel F seen from front to back successively.
    In a first, front section (here: in the car 10, but this could also be in the car 8), the rail vehicle 1 optionally has a small iron release device 23 for mechanical release, separation, removal or the like. of the iron, by means of which the old rails 6 'are attached to the old sleepers 5'. The iron 24 may be, for example, screws, nuts, bolts, staples, springs, etc., as known to those skilled in the art. The iron-iron release device 23 opens, disconnects or removes the iron 24 destructively or non-destructively. For example, the ironing release device 23 comprises drills, rotary hammers, chisels, cutting torches, cutting wheels, water jet cutters, lasers or the like, by means of which the iron 24 is mechanically released, separated or destroyed during the passage of the rail vehicle 1.
    The iron 24 may also be automatically released by the iron removal device 23, e.g. placed in the middle between the old rails 6 'and / or by an integrated receiving device, e.g. a gripper, a blade, a magnet or the like, e.g. a magnetic conveyor belt (not shown), collected and stored in a storage container.
    Following the optional ironing release device 23, the rail vehicle 1 has a Ausfädeleinrichtung 25 for the old rails 6 'in order to spread them to the outside. The old rails 6 'which are spread outwards by the Ausfädeleinrichtung 25 (in broken lines drawn in broken lines in Fig. 1b) are e.g. stored in a conventional manner laterally outside of the original track 4 and disassembled in sections for removal.
    In the embodiment shown in Fig. 1b, the Ausfädeleinrichtung 25 is the first component in a central working area A of the rail vehicle 1, which lies between the two front chassis 8 'and 8 "of the carriage 8.
    Subsequent to the old rail Ausfädeleinrichtung 25, the rail vehicle 1 is supported in the working area A optional means of a drive train 26 at the initially remaining without rails old sleepers 5 'from. The drive train 26 thereby generates propulsion for the rail vehicle 1 by rolling on the old rails 5 '.
    The optional drive train 26 is followed by a removal device 27 for the old sleepers 5 '. The removal device 27 grips the old sleepers 5 ', for example by means of a gripper 28 on the sleepers heads and puts them on the conveyor belt 14, which leads to the carriage 10 with the old-threshold storage.
    Subsequent to the removal device 27, the rail vehicle 1 has a ballast bed clearing device 29. The ballast bed clearing device 29 carries the entire ballast bed 3 down to the ground 7, either only in a central area 30 (FIG. 3 a) directly below the track 4, so that gravel bed edges 31 remain for the time being, or the same across the entire width of the ballast bed 3, ie Including the ballast bed edges 31. It is also possible that the ballast bed clearing device 29 clears so wide that it also clears the adjacent to the flanks 31 edge paths 32 next to the ballast bed 3 or cleans.
    As shown in FIGS. 3b and 3c, the ballast bed clearing device 29 can also dip slightly and in particular asymmetrically or obliquely into the plane 7 in order to make it horizontal or wedge-shaped, ie. with a transverse to the direction of travel F inclined planum surface 7 ', remove. Such a sloping planum surface 7 'serves to drain the track superstructure 2, so that rainwater which seeps through the ballast bed 3 and strikes the compacted planum surface 7' is removed transversely to the direction of travel F.
    The ballast bed clearing device 29 may be, for example, a transverse across the ballast bed 3 clearing chain, which is guided in its rear region obliquely upwards over the conveyor belt 17, which the old ballast 3 'to
    Rezyklierwagen 15 promotes. 4 shows an alternative embodiment of the ballast bed reamer 29 in the form of a pair of counter-rotating augers 34 supported on one side of a carrier 33 of the rail vehicle 1, which cooperate with lateral plowshares, baffles or shields 35 around the central area 30 or the area 30 including the flanks 31 or to clear the area 30 including the flanks 31 and the edge regions 32. The screw conveyors 34 convey directly onto the conveyor belt 17 pulled down there. For noise reduction, the conveyor belt 17 may be designed as a plastic conveyor belt.
    The side plowshares, baffles or shields 35 may be pivotally mounted on the carrier 33 as shown at 36 to adjust the clearing width of the ballast bed reamer 29. In the same way, the augers 34 may be pivotally mounted on the carrier 33 in order to optimally adapt their conveying effect to the opening angle of the shields 35.
    Returning to Figure 1b, the ballast bed clearing means 29 - particularly when it clears the ballast bed 3 via the central area 30 (Figure 3a) including the flanks 31 and edge paths 32 - optionally has an unwinding device 38 for unrolling a geotextile 39 onto the now exposed surface 7 subordinate to the subgrade 7.
    Following the ballast bed clearing device 29 or the optional geotextile unwinding device 38, the rail vehicle 1 has a ballast bed application device 40. A first embodiment of the ballast bed applicator 40 is shown in Fig. 1b, a second embodiment in Fig. 2. The ballast bed applicator 40 is Neuschotter 3 "from the Rezyklierwagen 15, more precisely the output of the high-performance sieve 16, optionally supplemented by Neuschotter 3" from the silo unit 22, fed via the conveyor belt 21.
    The ballast bed applying means 40 is adapted to apply the new ballast 3 "in at least two layers, a first, lower ballast layer 3a and a second overlying ballast layer 3b, to which the ballast bed applicator 40 sequentially includes a first ballast applicator 41 for application the first ballast layer 3a, a compacting device 42 for compacting the first ballast layer 3a, and then a second ballast applying device 43 for applying the second ballast layer 3b.
    It goes without saying that the ballast bed application device 40 can apply the new ballot 3 "in more than two layers 3a, 3b and can also have more than two ballast application devices 41, 43, between each of which a corresponding compacting device 42 lies.
    In the embodiment of Fig. 1b, the two ballast applicators 41 and 43 are conveyer belts or shafts fed by a common hopper 44 which is fed with new ballast 3 "by the conveyor belt 21. The compactor 42 is a squeegee or preferred a jolting unit, for example a hydraulically operated vibrating plate, which compresses the first ballast layer 3a.
    Between the compactor 42 and the second ballast applicator 43, the ballast bed applicator 40 may include an optional unwinding device 45 for applying a geotextile 46 to the top of the first ballast layer 3a that has just been compacted.
    The ballast bed applicator 40 applies the new ballast 3 "in the two layers 3a and 3b over the same width of the track superstructure 2 previously cleared by the ballast bed reamer 29, ie either over the central area 30 or the area 30 plus the flanks 31st
    2 shows an alternative embodiment of the two-stage ballast bed applicator 40 in the form of a funnel 47 with a first outlet chute 48 forming the first ballast applicator 41 and a second downstream outlet chute 49 forming the second ballast applicator 43. The hopper 47 is charged with Neuschotter 3 "from the conveyor belt 21, wherein the Neuschotter 3" divided by a central separator 50 in the hopper 47 on the two outlet shafts 48, 49.
    The central separating element 50 can be designed as a compression device 42, for example as a doctor blade or, preferably, as a hydraulically operated vibrating beam, which compresses the neoplate 3 "emerging via the outlet shaft 48 as the lower layer 3 a.
    Instead of or in addition to a design of the separating element 50 as a compacting device, one (or more) conveying screws 51 with an axis running transversely to the direction of travel F 1 can be arranged in the first ballast application device 41. The screw conveyor (s) 51 compresses / compacts by its conveying action the emerging from the outlet shaft 48 Neuschotter 3 ", so that the ballast layer 3 a emerges compacted.
    If desired, the ballast bed applicator 40 may be followed by a further compactor (not shown) for compacting also the upper ballast layer 3b.
    Optionally, the ballast bed applicator 40 may be configured to apply one or both of the ballast layers 3a, 3b having a wedge-shaped cross-section, as viewed in FIGS. 3b and 3c, as seen transverse to the direction of travel F. In Fig. 3b, the surface 7 'of the turf 7 is horizontal, while in the example of Fig. 3c has been removed wedge-shaped for drainage. The surface inclination of the gravel wedge resulting from the two layers 3a and 3b of new ballast 3 "can even run counter to the surface inclination of the subgrade 7. This can be done in bows, for example, a drainage towards the bow outside, while the ballast wedge 3 the cant Track overhangs of 120 to 160 mm are possible with such a ballast bed applicator 40. Only the first ballast layer 3a or only the second ballast layer 3b can be wedge-shaped or both ballast layers 3a, 3b ,
    The wedge-shaped shape of the gravel layers 3a, 3b can be achieved by appropriate design of the outlet shafts of the ballast applicators 41, 43, for example, by appropriate wedge-shaped design of the exit column, located at the exit of the outlet shaft 48 between the planum surface 7 'and the separator 50 and Exit the outlet shaft 49 between the surface of the layer 3a and the shaft wall 47 result. The term "wedge-shaped" in the present description is also understood to mean a trapezoidal shape, as used e.g. is shown in Figs. 3b and 3c.
    Since the production of a wedge-shaped ballast bed for bends in arcs during operation, the rail vehicle 1 is inclined towards the bow interior, the Neuschotter 3 "must be promoted in the ballast bed applicator 40 against gravity to the bow outside, so that it is not predominantly at the deepest To this end, one or both ballast bed applicators 41, 43 may include a cross conveyor which conveys new ballast 3 "to the wedge base of the ballast wedge to counteract the gravitational force of the rail vehicle 1 inclined transversely to the direction of travel. In the embodiment of FIG. 2, for example, the conveyor screw 51 can be used for this purpose if its conveying direction is selected such that it conveys the neoplate 3 "impinging on it in the direction of the outside of the sheet, so that it is increasingly released from the outlet shaft 48 there Such a conveyor screw 51 can for this purpose also be arranged in the outlet chute 49. However, such transverse conveyors in the ballast application devices 41, 43 can also be realized in other ways, for example by conveyor belts, rakes etc. running transversely to the direction of travel F.
    Returning to Figures 1b and 1c, on the rail vehicle 1, after the ballast bed applicator 40, a discard device 52 for depositing the new sleepers 5 "is placed on the new ballast bed 3. The new-wave laydown device 52 is moved over the conveyor belt 13 and the gantry crane 12 from the Neuschwellenvorrat the carriage 11 The Able-geeinrichtung 52 includes, for example, a corresponding separating device (not shown) for exactly adjusted storage of the costs incurred at the end of the conveyor belt 13 Neuschwellen 5 ".
    Subsequent to the new-wave laying device 52, the rail vehicle 1 may optionally be equipped with a supporting ski 53, which slides on the newly laid new shafts 5 "for supporting the rail vehicle 1 or unrolls it by means of a bead.
    After the new-wave laying device 52 and the optional supporting ski 53, a threading device 54 is provided for new rails 6 ", which were prepared laterally of the track body, eg laced there into strands Neuschwellen 5 "filed.
    In the area of the new rail threading device 54, an air conditioning device 54 'can optionally be arranged to bring the new rails 6 "to the correct temperature, eg 16-22 ° C., so that they already have the correct pretension in the installation position and for subsequent welding The air-conditioning device 54 'may, for example, include an inductive heating device and / or a cooling unit, for example a water-cooling system.
    A subsequent ironing attachment device 55 automatically fixes the threaded new rails 6 "on the new sleepers 5". The ironing attachment device 55 may be, for example, an automatic screw, bolt, stapler or welding machine.
    If the ballast bed clearing device 29 and the ballast bed application device 40 have not yet also cleared and replaced the ballast bed edges 31, the rail vehicle 1 contains on each track side a sheet pile edge clearing device 56 with a downstream ballast bed side application device 57. The ballast bed flanks -Räumeinrichtung 56 may for example be a clearing chain, which the old ballast 3 'from the edges 31 of the ballast bed 3, possibly together with residual material from the edge paths 32, abfördert on the conveyor belt 18, which leads to the re-cycling wagon 15. The ballast bed edges
    Applicator 57 is in turn charged by the conveyor belt 20 with Neuschotter 3 "from the Rezyklierwagen 15 to fill the flanks 31 of the ballast bed 3.
    FIG. 5 shows an alternative embodiment of the sheet bed side sweepers 56 on both sides of the track 4. Instead of a clearing chain, each ballast bed side skimmer 56 includes one (or two) counter-rotating conveyor screw (s) 58 mounted on one side of a support 57 of the rail vehicle 1 , which cooperates with side plowshares, baffles or shields 59, 60 or cooperate to clear the flanks 31 and possibly also the edge regions 32. The screw conveyors 58 each transport to a conveyor belt 20, which may be designed for the purpose of noise insulation as a plastic conveyor belt.
    The plowshares, baffles or shields 59, 60 may be pivotally hinged to the carrier 57 to adjust the clearing width of each ballast bed clearing 56. The middle shields 59, which serve to delimit between the central area 30 and the flanks 31 of the ballast bed 3, can be fixed in the manner of cutting.
    Returning to Fig. 1c, following the optional components 55, 56 and 57, the rail vehicle 1 has a tamping aggregate 61 with tufts 62 for stuffing the new track 4 with the new ballot 3 "in the new ballast bed 3. The tamping aggregate 61 can, As known in the art, be combined with a track lifting and straightening unit 63 to adjust the track 4 equal in the new ballast bed 3 correctly.
    The tamping picks 62 of the tamping unit 61 preferably enter the lower layer 3a when no geotextile 46 is used. In exceptional cases, and when using a geo-textile 46, the tamping punches 62 can also only reach down into the upper layer 3b of the new track bed 3 and leave the compacted lower layer 3a and the optional geotextile 46 untouched. In the course of the Gleisstopfens with the Stopfaggregat 61 also further Neuschotter 3 "can be filled to miteinzuschottern, for example, the threshold heads of Neuschwellen 5".
    The invention is not limited to the illustrated embodiments, but includes all variants, modifications, and combinations that fall within the scope of the appended claims.
