Description

The invention relates to a machine for the lateral displacement of a track consisting of rails and cross sleepers, with a machine frame mounted on bogies, on which a height and side adjustable track lifting and moving unit with rolling tools and one for aligning individual inclined sleepers in the track plane an alignment tool provided, adjustable in the longitudinal direction and the height of the device, and at least one tamping unit with adjustable and vibratable tamping tools which is adjustable via a drive.

According to DE-PS 893 956, such a machine is known for moving a track back or to the side. This machine has a machine frame mounted at the end on bogies, which is connected in the middle to a height and side adjustable rear head designed as a track lifting and moving unit with rolling or rear tools. A height-adjustable tamping unit with adjustable and vibratable tamping tools is provided on both sides of this back head. In addition, a device for aligning individual, inclined sleepers in the track plane, which is adjustable in the longitudinal direction and in height, is connected to the machine frame with pliers-like alignment tools.

Such machines for moving the track or shifting the side have the task of moving the tracks, particularly those laid in opencast mining operations, in accordance with the respective progress of mining a sole in mostly irregular periods of the mining front. The rails are made using roll-back tools a track lifting and moving unit detected and the entire track structure with continuous work priority of the machine driven by its own drive or by a locomotive machine by a relatively large amount of about 3o to 5o and also more centimeters laterally shifted from the original track position. After the end of this track back - due to the uneven track support, the unequal cross-shift resistance and the rough reverse process, by which the track is only torn out of its position - there is no exact track position with regard to the height and side position. The elevation errors in the backed track are mostly roughly compensated for by the tamping units arranged on the rear machine, whereby only visually recognizable large elevation errors are temporarily corrected depending on the experience of the operator without the aid of reference systems. A precise lateral and vertical alignment of the moved track is not possible, so that the speed of the transport vehicles moving on the moved track is only very low. With the track backing machine described, the back is made in such a way that the back of the head is adjusted accordingly by hand from the back dimension while the rolling tools are in contact with the rails and the machine is then moved on the track, with no intermediate adjustment possible - while driving . During the partially gradual return, inclined sleepers are aligned by the tongs-like device and the track is only temporarily supported by the tamping units without height and side position correction.

According to DE-PS 310 983, there is also known a further track-back machine with pinch rollers or rolling tools that can be placed on the rails. There are three of these on the rail side in the lower end area, a flange having pinch rollers provided, which are mounted on a frame connected to the machine frame. Together with the pinch rollers, this can be adjusted in height relative to the machine frame using two vertical screw spindles that can be operated by hand. Via two further screw spindles, which can be actuated by hand and run horizontally and transversely to the machine's longitudinal direction, the pinch rollers can be swiveled into contact with the rails or, after contact with the lifted track, can be moved laterally along the frame in accordance with the desired dimensions. With such, in particular by hand mechanically actuated pinch rollers, a corresponding height and side adjustment to the back of the track is only possible before the start of work of the backing machine, the adjustment to be carried out by hand being very time-consuming and before due to the relatively high weight of the track connected to the pinch rollers everything is also very tedious. A change in the selected height and side adjustment of the pinch rollers is therefore only possible if the work priority is interrupted and the screw spindles mentioned are actuated again.

Furthermore, according to DD-PS 100 510, a sleeper pressing device for aligning sleepers for retractable tracks is known. This threshold pressing device is arranged on a machine frame which is supported at the end by rail running gear and is located in the area of a rewind head with pinch rollers of the abovementioned type and is designed in the form of two raisable and lowerable plungers, each with a V-shaped plunger tip. Hydraulic working cylinders are provided for height adjustment and swiveling in the machine longitudinal direction. The pressing or aligning of the sleepers with this device takes place with the retracted roller head clamped and raised. The ram tip is sword-shaped formed, the end edges to each other form a relatively large angle of approximately 80 ° with each other, which thus makes penetration between two very closely spaced sleepers difficult. Due to the oscillating suspension, the ram tip moves along a circular path when the threshold is aligned. The point of contact of the plunger tip with the threshold moves upwards, and the resulting friction can also damage the thresholds.

It is also - according to AT-PS 373 646 by the same applicant or patent holder - a track tamping, leveling and straightening machine for tamping and accurate track position correction, in particular for precise lifting and lateral straightening. This track tamping machine has tamping units between two carriages that are spaced far apart from one another and a track lifting and straightening unit that is arranged upstream of this and articulatedly connected to a machine frame. Its support frame, which is connected to the machine frame by means of lifting and straightening drives, has wheel flanges and lifting rollers which can be attached to the rail as lifting and straightening tools. In order to create a precise reference basis for the target position of the track to be corrected, a leveling and straightening reference system arrangement formed from tensioned wires is provided. When the lifting and straightening drives are loaded, the track lifting and straightening unit - with the lifting and straightening tools - corresponding to the deviation of the actual track position from the target position - is raised slightly and / or slightly laterally by the lifting and straightening tools. Such lateral displacements range on average from about two to about ten millimeters. After using such a track leveling, tamping and straightening machine, the track is therefore in the correct height and lateral position.

The object of the invention is to create a machine of the type described in the introduction with which the track retraction process and the alignment of the sleepers can be carried out more quickly and easily, even on very heavy tracks.

This object is achieved with a machine of the type described in the introduction in that the sleeper alignment device, which is adjustable in the longitudinal direction of the track, forms a common, compact working unit with the common unit support frame with the hydraulic cylinder articulated on the machine frame with the track lifting and shifting assembly - Piston drives for height and side adjustment are articulated. This inventive design of a compact work unit with hydraulic cylinder-piston drives, a remote-controlled and therefore quick and easy to perform height and side adjustment of the track lifting and moving unit together with the threshold alignment device can be achieved for a correspondingly large backward distance. It is particularly advantageous that the desired changes in height and lateral adjustment can thus be carried out even during the track return process without interrupting the machine's right of way. In addition, during the alignment process of the sleepers, which is preferably carried out during the machine return, rough, clearly recognizable lateral position errors of the track can be corrected. In the case of larger sections with sleepers not shifted during the return process, i.e. properly aligned sleepers, the track can be lowered onto the ballast bed by remotely actuated actuation of the hydraulic cylinder-piston drives and, if necessary, the rolling tools can be briefly released from the rails for faster travel will. As a result of the union of the sleeper alignment device with the track lifting and Shifting unit to a compact work unit ensures automatic centering of the sleeper alignment device together with the unit frame connected to the rails via the rolling tools with respect to the track. This is also of advantage because, when the track is moved, there is a relatively large and irregular deviation from the center line of the machine frame, particularly in the case of large backward movements. Due to the known alignment devices connected to the machine frame, it must essentially be re-centered at each threshold to be aligned. This is avoided with the arrangement according to the invention.

Another advantageous development of the machine according to the invention is that the unit support frame has essentially a T-shape with its longitudinal support extending approximately centrally and in the longitudinal direction of the machine and around a joint running at the free end of the longitudinal support via one each on the end region of a cross-member articulated height adjustment drive and the side-adjustment drives articulated on both sides of the longitudinal support of the height and the side or on all sides to the machine frame is pivotally mounted. This unit support frame, which has a simple design and is connected to height and side adjustment drives, is particularly robust and highly resilient for the transmission of high lifting and return forces. A simultaneous transmission of lifting and return forces is also possible without problems via the hydraulic drives.

Another particularly advantageous development of the machine according to the invention is that the threshold alignment device is provided on the cross member of the T-shaped unit support frame and is height-adjustable on the latter via a hydraulic cylinder-piston arrangement is mounted and that in the region of the ends of the cross-member each have a tool carrier equipped with one of the two height adjustment drives, a swivel-in or out roll-lifting or shifting tool pair and a wheel flange wheel undercarriage is, the T-shaped unit support frame with its joint provided at the end of the longitudinal support articulated on the machine frame and mounted longitudinally displaceably via a guide and articulated with a piston-cylinder drive, preferably hydraulically actuated in the machine longitudinal direction. With such an arrangement of the threshold alignment device and the roll-lifting tools, with a particularly good overview by the operator, any mutual interference is reliably excluded. Due to the longitudinal displaceability of the unit support frame, in addition to the threshold alignment, it is also possible for the alignment device to be centered quickly and precisely above the threshold to be displaced. This means that there is no need for centering by the machines in an advantageous and energy-saving manner.

An advantageous development of the invention also consists in that an alignment tool designed as a plunger is provided at least at each end of the cross member and preferably also in the center of the cross member of the unit support frame, each tool plunger in one with the Cross-beam is firmly connected to the carrier guide via a hydraulic cylinder-piston arrangement adjustable in height. The arrangement of three tool plungers spaced as far apart as possible, each of which can be actuated independently of one another by a separate drive, means that sleepers that are very close to each other can also be quickly pushed apart and brought into the correct position. By fixed with the cross beam connected carrier guide, an essentially torsion-free power transmission can also be achieved.

According to a further advantageous embodiment of the invention, all three alignment tools or plungers of the threshold alignment device, which are height-adjustable to the unit support frame, are each wedge-shaped or pointed-cone-shaped at their lower ends and preferably have a thickness of approximately 6 cm. An alignment tool designed in this way in a bolt-like manner can be inserted easily, quickly and reliably, even in a very small gap between two closely spaced sleepers for rapid alignment thereof.

A particularly preferred embodiment of the invention is that the common unit support frame with the track lifting, moving and aligning tools between the two, widely spaced undercarriages of a machine designed for leveling or lifting and lateral straightening and immediately one downstream in the working direction The tamping unit is arranged below the machine frame, with the lifting and moving tools being assigned a leveling and straightening reference system arrangement provided on the machine for carrying out lifting and moving or returning operations and / or leveling and side straightening operations . A rear machine designed with these features is for the first time in a particularly advantageous and economical manner not only for the rough back of the track with a correspondingly large return path of about 30 to 50 and more centimeters, but also for an advantageously subsequent correcting of the track position with precise height leveling and laterally Fine alignment of the track can be used in the millimeter range. It is also of particular advantage that the to the Track back subsequent precise track position correction can be practically carried out in one go without additional time-consuming and labor-intensive retrofitting work. This can be achieved above all in that, according to the invention, the tools required for the back of the track and the exact correction of the track position are arranged on a common unit support frame which is connected to the machine frame via remote-controlled hydraulic cylinder-piston drives. The back of the track which occurs in the first step with a very wide displacement of the track can advantageously take place with the reference system arrangement switched off, since such a large transverse displacement cannot lead to an exact track position. On a subsequent machine return, any inclined sleepers are aligned by lowering the alignment tools, which are automatically centered by the common unit support frame, while acting on the assigned drives and longitudinally displacing the support frame. On a subsequent return trip of the machine designed according to the invention, with the addition of the reference system arrangement and the tamping units, an exact leveling and lateral alignment of the track in the millimeter range can then take place, so that after the second outward journey of the machine, an exact track position of the track being moved can be achieved. On such a track, transport trains with higher transport performance can be moved more quietly, safely and quickly. If the track is shifted or shifted even more, the track can be moved again before the exact track correction.

A useful development of the invention is that on one side of the cross member of the common T-shaped unit support frame, preferably the side of the cross member facing the tamping unit Lifting, rolling and / or straightening tools and on the other side of the crossmember facing away from the tamping unit, preferably the three independently adjustable height-adjustable tappets of the alignment device. With such a simple arrangement or division of the lifting, returning and straightening tools as well as the tool tappet on the unit support frame, an unimpeded track lifting can be carried out as close as possible to the tamping units.

An advantageous development of the invention provides that the common work unit - in addition to an operator's cab assigned to the tamping and lifting and straightening tools - a work booth provided between the two trolleys and in the area above the common T-shaped unit support frame on the machine frame assigned. This additional work cabin makes it particularly easy to see the alignment tools, so that quick and accurate alignment of inclined sleepers towards the back of the track can be achieved even while avoiding threshold damage.

Another useful development of the invention is that the common work unit - especially for large displacement or return movements of the track - in addition to the two preferably bogie bogies in the area of the two ends below the machine frame each have a height-adjustable cross-crawler undercarriage and preferably one each between the bogie chassis and crawler chassis provided height-adjustable plow is assigned. These caterpillar tracks, which are arranged at the end of the machine frame, enable rapid disengagement from the track or, conversely, rapid insertion of the machine, so that the transport train running on the track is not disturbed in any way becomes. With particularly large ranges and high lateral shift resistance, a reverse operation can also take place locally when the crawler tracks are lowered. With the height-adjustable plows, larger amounts of overburden lying on the track can be removed or the formation for the new position of the track behind the back can be planned in an advantageous manner.

According to a further advantageous embodiment of the invention, the side displacement path of the rolling or lifting and displacement tools arranged on the unit support frame for the back of the track is at least approximately half a threshold division, preferably approximately half the track width, e.g. approx. 70 cm, the distance between the two bogie bogies arranged on both sides of the working unit being at least about twelve to fourteen threshold divisions or preferably about 10 m. With such a minimum backswing, an economical, efficient track back and straightening can be carried out so that the rails and rail fastenings are not overstressed.

The invention also relates to a method for laterally shifting a track. This method is characterized in that during a first continuous work approach, the track grasped and lifted by the rolling or backing tools of the work unit is shifted to the side in a relatively wide range from approximately 30 to approximately 50 cm, and preferably during a partial gradual step Return of the machine inclined sleepers of the side-shifted track by lowering the alignment tools and corresponding longitudinal displacement of the unit support frame in the correct position, after which the track is preferably during an opposite second step-by-step approach through the tamping, Lifting and rolling-straightening tools are supported, leveled and aligned using the reference system arrangement. With such a sequence of three expediently carried out operations one after the other, a track that is corrected in terms of height and side is available in a particularly economical and rapid manner immediately after the back of the track. This rapid completion of work is also advantageous in that the train or transport traffic taking place on the track is not adversely affected. In addition, the correct track position immediately after the track back enables the track to be driven quickly for an unrestricted high transport performance.

The invention is described in more detail below with reference to an embodiment shown in the drawing.

A machine 1 shown in FIG. 1 for laterally displacing a track formed by rails 2 and cross sleepers 3 has an elongated machine frame 5 mounted on bogie undercarriages 4. A travel drive 6, like all drives on the machine, is supplied with energy by a motor 7 connected to a hydraulic pump unit. A central control device 9 is provided in an operator's cabin 8. A work cabin 10 is also connected to the machine frame 5 between the two bogie undercarriages 4. Between the operator and work cabin 8, 10, a track lifting and moving unit 13 with rolling or lifting and moving tools 14 is arranged, which is adjustable in height and laterally via drives 11, 12.

As can be seen in FIG. 1 and in particular in FIGS. 3, 4 and 5, a threshold alignment device 16 connected to an alignment tool 15 forms with the Track lifting and moving unit 13 a common compact work unit 17 with a common unit support frame 18. This is articulated to the hydraulic frame-piston drives 11, 12 articulated on the machine frame 5 for height and side adjustment. The unit support frame 18 essentially has a T-shape with its longitudinal support 19 running approximately centrally and in the machine longitudinal direction (see FIG. 4). A joint 20 running at the free end of the longitudinal support 19 is via a height adjustment drive 11 articulated on the end region of a crossmember 21 and the side adjustment drives 12 articulated on both sides of the longitudinal support 19 in height and on the side or on all sides to the machine frame 5 pivotally mounted.

As shown in FIGS. 1 and 2, the common unit support frame 18 with the track lifting, moving and aligning tools 14, 15 between the two bogie undercarriages 4, which are spaced far apart from one another, is also designed for leveling or lifting and side-aligning Machine 1 and a tamping unit 22 arranged downstream in the working direction are arranged below the machine frame 5. The lifting and moving tools 14 - for back and side straightening - is a leveling and directional reference system arrangement 23 provided on the machine 1 and formed from a tensioned wire for executing lifting and moving or returning processes and / or leveling and side straightening assignments. The tamping unit 22, which is height-adjustable via a drive 24, has tamping tools 25 which can be set and vibrated via auxiliary and vibration drives. Between the tamping and the track lifting and moving unit 13, 22 there is arranged a height-adjustable sensing roller 26 which can be unrolled on the rails and is assigned to the leveling and directional reference system arrangement 23. The common work unit 17 is - especially for large displacement or return movements X of the track 27 - in the area of the two ends below the machine frame 5, a transverse crawler track 28, which is height-adjustable via a drive and has its own travel drive, and one each - arranged for use in the opposite working direction - and also assigned height-adjustable plow 29 each via a drive. An auxiliary crane 3o is attached to the end of the machine frame 5 opposite the operator's cabin 8. The leveling and straightening reference system arrangement 23 has a side straightening chord 31 and a height or leveling chord 32. Each bogie undercarriage 4 is connected to a rail support device 33, which is height-adjustable via a drive, for resting on the rails 2.

The track lifting and shifting unit 13 shown schematically in FIG. 2 during a track return process can be shifted laterally out of the longitudinal center line of the machine 1 by appropriate loading of one or the other side shifting drive 12 at a relatively large distance of, for example, about 30 cm. or pivotable. The track 27 gripped by the lifting and moving tools 14 is also laterally shifted by this amount (see arrow 34). The original position of the track 27 is shown here with dashed lines 35. The difference between this original position 35 and the position of the track 27 shown in full lines after a first track return process by the machine 1 essentially corresponds to the return or displacement dimension. The working direction of the machine 1 is shown by an arrow 36.

In the schematic representation according to FIG. 3, the working direction of the machine 1 is indicated by arrows 37 designated. During the gradual work approach, one or the other inclined threshold 3 is aligned with the help of the alignment tools 15 arranged on the common work unit 17. The lifting and moving tools 14 are preferably in the pivoted-up position and are not in engagement with the rails 2. The track lifting and moving or straightening unit 13 combined with the alignment device 16 is arranged centrally with respect to the longitudinal center line of the machine 1.

In the schematic representation according to FIG. 4, the working direction of the incrementally advancing machine 1, indicated by the arrows 36, corresponds to the working direction according to the continuously advancing machine 1 according to FIG. However, the height and side shift drives 11, 12 of the track lifting and shifting unit 13 are controlled by the leveling and directional reference system arrangement 23 in accordance with the determined deviations of the actual from the target position of the track 27, so that behind in the working direction the lifting and moving tools 14 there is a track 27 that is precisely corrected in terms of height and side by the tamping, lifting and straightening or moving tools 25, 14.

As can be seen in FIGS. 5, 6 and 7, the threshold alignment device 16 is provided on the cross member 21 of the T-shaped unit support frame 18 and is mounted on the cross member 21 in a height-adjustable manner by means of a hydraulic cylinder-piston arrangement 38. In the area of the ends of the crossmember 21 is a tool carrier equipped with one of the two height adjustment drives 11, a pair of roll-lifting or displacement tools 14 that can be swiveled in or out via drives 39, and a wheel flange wheel undercarriage 40 41 arranged. The T-shaped unit support frame 18 is at the end of the longitudinal Support 19 provided joint 20 on the machine frame 5 articulated and mounted longitudinally displaceably via a guide 42 and articulated with a piston-cylinder drive 43 which can be acted upon hydraulically in the longitudinal direction of the machine.

5, 6 and 7 also show that an alignment tool 15 designed as a plunger 44 is provided at each end of the cross member 21 and also centrally on the cross member 21 of the unit support frame 18. Each plunger 44 is mounted in height-adjustable manner in a carrier guide 45, which is fixedly connected to the cross-member 21, via a hydraulic cylinder-piston drive 38. All three alignment tools 15 and plungers 44 of the threshold alignment device 16, which are height-adjustable to the unit support frame 18, are each wedge-shaped or cone-shaped at their lower ends and preferably have a thickness of approximately 6 cm. In addition, all three plungers 44 fastened to the cross member 21 are designed to be height-adjustable independently of one another via their drives. The lateral displacement path X of the rolling or lifting and displacement tools 14 arranged on the unit support frame 18 for the back of the track is at least approximately half a threshold division to preferably approximately half the track width, e.g. 70 cm, the distance X 1 of the two bogie bogies 4 arranged on both sides of the working unit 17 corresponding to one another at least about twelve to fourteen threshold divisions or preferably about 10 m.

The mode of operation of the machine 1 designed according to the invention for laterally shifting a track is described in more detail below:
As soon as, for example, in opencast mining operations an advancement of the Track 27 is required, the machine 1 is moved to the track section. This can be done via the own bogie bogies 4 or in a track insertion process by means of the height-adjustable and drivable transverse crawler tracks 28. After reaching the point of use, the working unit 17 is lowered onto the rails 2 until the flanged wheel undercarriages 40 are placed under the action of the height shift drives 11. Thereafter, the paired rolling or lifting and shifting tools 14 are placed on the rails 2 while acting on the drives 39. The two rail support devices 33 are also lowered onto the rails 2. The two crawler tracks 28 and plows 29 arranged at the ends, like the tamping units 22 and the feeler roller 26, remain in the state lifted off the track 27.

With a slight increase in the working unit 17 by acting on the two hydraulic cylinder-piston drives 11, the track 27 in the region of the unit support frame 18 is raised accordingly. By correspondingly acting on the two hydraulic cylinder-piston drives 12, the Entire work unit 17 together with the track 27 laterally shifted at a relatively large distance of approx. 30 cm (if necessary also during the right of way) (see arrow 34 in Fig. 2). While maintaining this strongly eccentric position of the working unit 17 in relation to the longitudinal center line of the machine 1, the latter is moved continuously in the direction of arrow 36 in a first working direction (FIG. 2) when the travel drive 6 is started - or also by a locomotive. The arrangement of the hydraulic cylinder-piston drives 11, 12 as a connection between the working unit 17 and the machine frame 5 enables the operator in the working cabin 10 to do so during this to intervene continuously in the right of way by remotely actuating the hydraulic drives 11 and 12 mentioned. In the event that, for example, due to a larger accumulation of ballast, the track 27 to be moved with the sleepers 3 rests on the ballast bed on this wave crest, a rapid height adjustment of the entire working unit 17 can be achieved by quickly actuating the hydraulic cylinder-piston drives 11 and thus also the track 27 can be carried out. In the known machines, in which only manual adjustment of the work unit is possible only when the machine is at a standstill via appropriate spindle drives, the track would in such a case continue to rest on the ballast bed during the lateral shift and thus lead to faults or to lead to an increased load on the track. Due to the possibility according to the invention of a precise coordination of the lateral displacement and height adjustment of the working unit 17 together with the track 27, a greater work performance can therefore be achieved overall by an increased speed of advance.

After completion of the track back as part of the first work approach, the machine 1 is moved in the opposite direction (see Fig. 3) - for example when returning in a second - but partially step-by-step work approach, the lifting and moving tools 14 of the Track lifting and moving unit 13 need not be in engagement with the rails 2. In this second work approach, the sleepers 3, which are shifted obliquely by the back of the track, are aligned in a correct position with respect to the rails 2 by lowering the tappets 44 between the sleepers 3 while acting on the associated hydraulic cylinder-piston arrangement 38. This takes place at a standstill of the machine 1, the unit support frame 18 being displaced longitudinally in the guide 42 depending on the position of the threshold 3 to be aligned by acting on the piston-cylinder drive 43. This results in one or the other, or all three, lowered plungers 44 bearing against a side surface of the threshold 3 to be aligned, which is also longitudinally displaced with respect to the rail 2 when the unit support frame 18 is displaced longitudinally. As soon as the correctly aligned position of the threshold 3 is reached, the lowered rams 44 are raised again and the machine 1 is moved to the next threshold 3 to be aligned. During this second work approach there is also the advantageous possibility of reducing particularly large and conspicuous lateral position errors of the track 27 by briefly placing the lifting and moving tools 14 on the rail 2 and applying the lateral shift drives 12 accordingly. Such a corrective intervention - which considerably simplifies the subsequent fine straightening work - is only possible by arranging hydraulic cylinder-piston drives 11, 12 in connection with the working unit 17 with the machine frame 5. Then, by appropriately loading the drives 39, the lifting and moving tools 14 can be quickly brought out of engagement with the rails 2 again and the threshold alignment process can be carried out in the manner described.

After the threshold alignment process has been completed as part of the second work priority, a third work priority takes place, preferably in the same working direction as the first work approach to the back of the track. In this third continuous work approach for accurate track position correction, the leveling and directional reference system arrangement 23 is switched on and the sensing roller 26 lowered onto the rails 2. The deviation of the actual track position from the target position formed by the lateral direction chord 31 or the height chord 32 is determined. In accordance with this difference in height and lateral position of the track 27 ascertained in the control device 9, the hydraulic cylinder-piston drives 11 and 12 are acted upon, as a result of which there is a slight height and / or transverse displacement - left or right in relation to the track means line - The track 27 detected by the lifting and moving tools 14 can be carried out. The track 27 held in this way in the correct track position is stuffed by the stuffing tools 25 of the stuffing unit 22. The lateral displacement or alignment of the track 27 taking place takes place in relatively small areas of a few centimeters, the accuracy of the straightening process being in the millimeter range. This third - step-by-step - right of way with track position correction directly adjoining the back of the track can thus create a track that is precisely aligned in terms of its height and lateral position, which can be driven faster and more safely with higher axle pressures to achieve greater transport performance.

With the two plows 29 arranged at the ends, for example, the level on which the track 27 is to be moved can be leveled, or the overburden that has fallen onto the track can also be removed. In the context of the invention, the common working unit 17 can also be arranged projecting on the machine frame 5 via one of the two bogie running gears 4. Furthermore, only two alignment tools designed as plungers can be provided, and it is also advantageous that the alignment tools 15 each have their own hydraulic cylinder-piston drives - in addition to the longitudinal movement by the piston-cylinder drive 43 - in addition are formed independently of each other longitudinally.

The invention also relates to a method for laterally shifting a track with a machine designed according to the invention, in which, during a first continuous work approach, the track detected and lifted by the rolling or return tools 14 of the working unit 17 in a relatively wide range from approximately 30 to about 50 cm laterally, and preferably during a partial gradual return of the machine inclined sleepers 3 of the laterally displaced track by lowering the alignment tools 15 and corresponding longitudinal displacement of the unit support frame 18 in the correct position, preferably during an opposite second gradual Work priority is stuffed, leveled and aligned by the tamping, lifting and roll-straightening tools using the reference system arrangement 23. With this method it is therefore possible for the first time to advantageously carry out both the backward or shifting work and the threshold alignment work as well as the leveling, straightening and tamping work with one and the same machine 1.
