Abstract

The invention relates to a device for the height and lateral alignment and/or support of the rails (13, 14) of a railway track (11), in which the support elements (21, 22) for the rails (13, 14) are configured as pendulum supports (30) and diagonally reinforced by a longitudinally adjustable pulling/pushing element (42). By extending or shortening said element the rails, which are connected to each other by a connecting element (39), can be laterally displaced. This also simultaneously eliminates any play between the rails (13, 14) and their fixing means (15).

Description

Title: Device for the vertical and lateral alignment and / or support of the rails of a track

The invention relates to a device for height and side alignment and / or support of the rails of a track on the support plates of a solid carriageway, with a connecting element connecting both rails and with height-adjustable support elements for each rail.

Tracks for high-speed trains require a solid track, which consists of a monolithic, hydraulically bound base layer and continuous concrete support plates, with which the ^" track ^{" is} firmly connected. It is ^' usual here to design the support plates in the form of a U-shaped trough and to connect the sleepers made of concrete or steel to the support plates using in-situ concrete in which the track sleepers are embedded (Rheda system).

Before the sleepers are concreted in or otherwise firmly connected to the supporting plates, the track must be precisely aligned laterally and in height and held in this precisely aligned position until the final, firm connection to the ground is established. Alignment takes place either with vertical and horizontal screw spindles arranged on the sleepers or with track regulation portals (DE 195 08 107 Cl) supported on the side cheeks and on the base of the support plates, which align the individual sleepers with vertical and horizontal screw spindles.

It is also already known to align the track with a track straightening machine prior to concreting, which is vertical and acts on horizontal spindles that attack the sleepers of the track and adjust them laterally and in height (DE 38 20 656 AI).

These known methods are cumbersome and require specially designed sleepers which accommodate the screw spindles for height adjustment and possibly also for side adjustment. Furthermore, the rails are only aligned indirectly via the sleepers, and no precautions have been taken to ensure that the aligned track remains in place until it is finally firmly connected to the support plates. When installing long rail lengths, which are necessary for economical construction progress and good track quality, considerable length changes can occur in the rails due to temperature influences, which lead to a shift of the track, which is only supported by the vertical and horizontal spindles after alignment. These changes in length adversely affect the position of the track that has been set up, so that the track must be realigned. Since these spindles can not absorb large vertical forces, it is also not possible to use the laid and aligned rails as a route for the track straightener, but rather it must run on special auxiliary rails on both sides next to the laid track.

The object of the invention is to provide a device for aligning and supporting a track laid on a solid carriageway of the type explained in more detail above in such a way that the track is laterally and vertically aligned with the rails and is supported such that it has high vertical loads in the installed state can accommodate and the alignment of the track is not affected by changes in length of the rails until the sleepers are finally connected to the ground.

This object is achieved with the invention in that the support elements for the first rail and the support elements for the second rail are designed as pendulum supports and are stiffened diagonally by a length-adjustable tension / compression element. This configuration has the advantage that the support elements designed as pendulum supports also transfer relatively large vertical loads directly from the rails to the support plates during the assembly state. Together with the connecting element and the diagonally running tension / compression element, two supports form a stable truss under the two rails, which ensures the necessary stability. Changes in the length of the rails due to temperature influences are easily possible thanks to the self-aligning bearing, while maintaining the exact height and side alignment.

Since the diagonal tension / compression element is adjustable in length, it can advantageously be used for lateral adjustment of the track without having an effect on the sleepers, which only take on support functions for the rails after they have been firmly connected to the ground.

It is expedient if the upper end of the pull / push element is connected to the connecting element which connects the rails to one another. The forces generated for lateral alignment by longitudinal adjustment of the tension / compression element are thus transmitted directly to the rails.

It is expedient if the tension / pressure element is connected in the vicinity of the first rail with a joint head on the connecting element and at a vertical distance from the second rail with an ankle joint on the support element for the second rail. This has the advantage that there are no constraints when aligning the track in the individual trusses and the straightening harnesses can also be used in track sections where track canting is required. In such stretches, the pendulum support with the connected ankle of the tension / pressure element is then expediently arranged under the non-inflated rail and the pendulum support with the head joint of the tension / pressure element under the elevated rail. The support elements designed as pendulum supports have a convex head bearing surface that supports the rail and a convex foot bearing surface supported on the support plates, which are curved according to a cylindrical surface or a spherical surface and are coordinated with one another in such a way that the vertical distance between the head bearing surface and Foot storage area hardly changed. In this way it is possible to maintain the exact vertical alignment of the track even if changes in length of the rails due to temperature influences bring the pendulum supports out of their vertical position. In addition, skewing the pendulum supports when aligning the sides does not affect the height of the track.

Each support element expediently has a shaft, a head part, a foot part and a lifting device for height adjustment, which are captively connected to one another. In order to be able to carry out the height adjustment easily from above, it is advantageous if the shaft of the support element consists of an upper shaft part and a lower shaft part, both of which are telescopically interlocking with one another from a lifting device designed as a spindle-nut drive are displaceable and if the head part has a support ball and a cap arranged between the rail foot and the support ball, which surrounds the support ball and is connected to the upper shaft part so that it can be tilted on all sides. A particularly light and simple construction results if the shaft parts consist of polygonal tubes, for example square tubes, which are inserted into one another. In this case, the nut of the spindle drive is expediently firmly connected to the lower shaft part, while the screw spindle of the spindle drive is rotatably but axially immovably mounted in a bearing plate fastened in the upper shaft part and carries the support ball. The spindle can be actuated by bevel gears from a drive pin inserted into the upper shaft part. The driven bevel gear is rotatably mounted together with the spindle in the bearing plate and secured against axial displacement by a locking pin, which also penetrates the walls of the upper shaft part and engages with plenty of play in the aligned openings of the cap, so that not only all Parts are captively connected to each other, but also the shaft to perform a tilting movement in all ^directions', in order to act as a pendulum support.

Furthermore, it is advantageous if the pull / push element has at one end an ankle with which it is attached to the foot part of a support element for the second rail. At its other end, which is connected to the connecting element, the pull / push element passes through or comprises the head part of the support element for the first rail with play. If a supporting element for the first rail and a supporting element for the second rail are then connected to one another in an articulated manner together with a connecting element and a pulling / pushing element, a straightening tableware results, the individual parts of which are connected and which is handled very simply and _. can be easily positioned when installing the track and can be easily folded, removed and stored or reused after its completion.

The connecting element can be a connecting rod which rests on the rail feet of the first and second rails with crankings at the rod ends. Such training facilitates the use of straightening harnesses, which can be easily pushed from above under a rail of the track and placed on the inner edges of the rail feet with the cranks before the attached pendulum supports can be swung out and into theirs with the help of the tension / pressure element vertical position.

In order to easily and directly transfer the straightening force generated by the pull / push element to the rails during side alignment, a rail foot clamp is arranged on at least one rod end of the connecting element, which clamp comprises the rail foot of a rail and to which the pull / push element is fastened with the joint head . So that the straightening harnesses are fixed on the support plates and do not move laterally when the rails are aligned laterally, the foot part of each support element has a coupling element for positive connection with the support plates. The coupling element can be a bar or groove formed on the bearing surface of the foot part, which engages in a groove or bar in the support plate. A groove can be formed in the support plate during its manufacture or cut subsequently.

In track sections that have to transmit high lateral forces, dowels or bolts can also be used as coupling elements, with which the straightening harnesses are connected to the ground and secured against shifting.

In a particular embodiment of the invention, the device for the lateral alignment and / or support of the rails of a track which are laterally supported on rail fastening means has a connecting element which is designed as a connecting rod, on the rod ends of which rail foot clamps are articulated, which clamps the rail feet of the first rail and the second rail comprise and have the tensioning devices which press the two rails laterally in the opposite direction against the rail fastening means assigned to them. This eliminates the play between a rail fastening means and the edge of the rail foot facing it and minimizes the influence of the fastening tolerances on the final track position. The track can then be aligned very precisely laterally, since after switching off the play between the rail foot and the fastener, only the inevitable dimensional tolerances during rail production affect the side adjustment.

A particularly simple construction results if the rail foot clamps engage behind the cranks on the rod end of the connecting rod and if the distance between the cranks on the connecting rod is smaller than the distance between the contact surfaces of the inner rail fastening means of both rails. The individual parts of the straightening harness then remain connected to one another when it is used and when it is not in use, and it is possible to place the straightening harness on the rail feet. Nevertheless, there is enough play between the cranks and the rail feet around the rails with the help of the rail foot clamps to press against the respective inner rail fastening means and thereby switch off any movement of the rails in the support.

If the support elements are provided with support balls and caps, the caps of the support elements for the first rail can be connected to the caps of the support elements for the second rail assigned to them in each case by a connecting rod. Each cap then supports the associated rail on at least one rail foot edge and on at least one cap of two supporting elements belonging to a straightening table, a tensioning device is provided, with which the two rails can be pressed apart or pressed together against their fastening means in order to thereby eliminate the bearing play .

For side alignment and / or support of the rails of a track on the support plates of a solid carriageway, in which the rails are connected by a connecting element connecting them, according to a further embodiment of the invention, length-adjustable pressure elements can also be used, which are located on the one side on the Support support plate arranged abutment and on the other hand with a claw on the edge of the rail foot of a rail. The abutments can be the side cheeks of a trough-shaped support plate, but it is also possible to provide cutouts or bumps on the surface of the support plate on which the pressure supports are supported. In contrast to the known straightening devices, the length-adjustable pressure elements do not act on the sleepers, but directly on a rail, which also transmit the side pressure generated by the pressure element via the connecting element or the sleepers to the second rail. Preferably, the length-adjustable pressure elements between the sleepers are alternately arranged on the left and right side of the track, so that the lateral alignment to both sides is possible. The vertical alignment of the track can then be carried out with other vertical support and alignment elements, such as are described and illustrated for example in the European patent application No. 98 114 179.9-2303 by the applicant. The length-adjustable printing elements can consist of a screw with a rotatable claw at one end and a nut at the other end, which is welded into a polygonal sheet metal sleeve, which is supported on the abutment of the support plate. Such printing elements are simple and inexpensive to manufacture and easy to handle from above.

On the support plates 10 of a solid carriageway, not shown here, a track 11 has been introduced, which is supported on the support plates 10 with leveling dishes 12, which are described in more detail below, and is aligned in height and laterally before it is fixed to the support plates 10 is connected. The track 11 consists of a first rail 13 and a second rail 14 which are fastened with rail fastening means 15 to sleepers 16, of which only one is indicated in broken lines in FIG. 1.

In the exemplary embodiment shown, the rail fastening means 15 are rib plates 17 which have an inner rib 18 and an outer rib 19, between which the rail foot 20 lies with little movement play (FIG. 4). The rail fastening means also include clamping screws which clamp the rail foot on the ribbed plate 17, but which are not shown here.

In other embodiments, tension clamps with angle guide plates are used, which absorb the lateral forces. The clamping screws can also be the rail fastening means alone and not only hold the rail foot in place, but also, like the ribs 18 and 19 of the rib plate, also support laterally.

The straightening harnesses 12 mentioned above are arranged and exist approximately in every third compartment between the sleepers each from a support element 21 for the first rail 13 and from a support element 22 for the second rail 14. The support elements 21 and 22 have a head part 23, a lifting device 24, a shaft 25 and a foot part 26, which parts, for example, by dovetail connections, hammer head screws or the like in T-shaped grooves. are captively connected.

The lifting device 24 can have various configurations, for example as a hydraulic lifting cylinder, articulated scissors or the like. be trained. In the embodiment shown in FIGS. 1 to 3, a simple wedge 27 with a tension spindle 28 is shown, which cooperates with a lower inclined surface 29 of the head part 23 and can be adjusted by turning the tension spindle head.

According to the invention, the support elements 21 and 22 are designed as pendulum supports 30. For this purpose, the head parts 23 have a convex head bearing surface 31 which carries the respective rail 13 or 14 and a convex foot bearing surface 32 which can be supported directly on the support plate 10, but in the exemplary embodiment shown is arranged on the underside of the shaft 25 and cooperates with a concave bearing surface 33 of the foot part 26. The convex head bearing surface 31 is always the cutout of a spherical surface, i.e. a spherical cap, while the corresponding foot bearing surfaces 32 and bearing surfaces 33 can be partial spherical surfaces or partial cylinder surfaces.

The foot part 26 of each pendulum support 30 has on its lower bearing surface 34 a coupling element 35 in the form of a strip 36 which is triangular in cross section and which engages in a groove 37 corresponding to the strip shape, which is formed in the surface 38 of the support plate 10 or subsequently cut and cut extends in the longitudinal direction of the rail 13 or 14. The coupling element 35 provides a positive connection between the support elements 21 and 22 on the one hand and the support plates 10 on the other hand, so that the straightening harnesses 12 do not laterally shift when the track 11 is aligned laterally. push, but can only pivot in their foot support surfaces 32.

In another embodiment, openings can be provided in the footplate, into which bolts are inserted, in order to ensure the transfer of the lateral forces.

The foot bearing surfaces 32 are in the support elements 21 and 22 of most straightening harnesses 12 spherical caps, so that the support elements can oscillate not only transversely to the rail but also in the longitudinal direction of the rail and do not impede changes in length of the rails 13 and 14 as a result of temperature changes. However, in order to avoid that the support yokes formed by the straightening harnesses 12 tip over in the longitudinal direction of the rail when large changes in the length of the rails act on them, specially trained straightening harnesses are used in the middle of the rail length, which is approximately ten to twenty meters, in which the Support elements 21 and 22 have foot bearing surfaces 32 which are curved towards a cylindrical surface, the cylinder axis of which runs parallel to the longitudinal direction of the rail. These support elements 21 and 22 then touch the bearing surface 33 of the foot part 26 along a line running parallel to the rail 13 or 14, so that the support elements cannot tilt in this direction. It is obvious that these special straightening harnesses are expediently arranged in the middle of each rail length to be installed, so that changes in the length of the rails resulting from temperature changes are distributed on both sides of this particular center yoke to the front and rear.

4 and 5, another embodiment of the support element 22 is shown, which can be used both under the first rail 13 and under the second rail 14.

In this support element 22, the shaft 25 consists of an upper shaft part 70 and a lower shaft part 71, which consist of polygonal tubes which are guided into one another, in the present exemplary embodiment of square square tubes. The un- tere shaft part 71 has at its lower end, not shown in FIGS. 4 and 5, a convex foot bearing surface and, like the support elements shown in FIGS. 2 and 3, is mounted on a foot part. At its upper end, the lower shaft part 71 carries a spindle nut 72 with a self-locking thread and is slidably guided in the interior of the upper shaft part 70.

At the upper end of the upper shaft part 70, a bearing plate 73 is welded, in which a driven bevel gear 74 is rotatably mounted, which is fastened to the upper end of a screw spindle 75 with a self-locking trapezoidal thread, which together with the spindle nut 72 forms a spindle nut drive. The driven bevel gear 74 has on its circumferential bearing surface 77 a circumferential groove 78 which is semicircular in cross section and into which a locking pin 79 engages. The locking pin 79 secures the driven bevel gear 74 in the bearing plate 73 and holds the bevel gear 74 and the screw spindle 75 firmly connected to it axially fixed relative to the bearing plate 73. The locking pin 79 also penetrates the walls 80 and 81 of the upper shaft part 70 and projects outwards beyond them.

It can be seen from FIGS. 4 and 5 that a cap 82 is arranged under the rail foot 20, which is bent downward in a U-shape in its central region 82a and overlaps the upper end of the upper shaft part 70 with two flanges 83 and 84. Openings 85 and 86 are arranged in these flanges 83 and 84, which are aligned with the protruding ends 79a and 79b of the locking pin 79 and surround them with plenty of play.

The cap 82 and the upper end of the upper shaft part 70 form the head part 23 of the support element 22 and are captively connected to one another by the locking pin 79. The non-positive connection between these parts is produced by a support ball 87 which lies in a spherical recess 88 of the screw spindle 75 and the driven bevel gear 74 and can roll on the lower surface 89 of the cap 82. It can be seen that the support ball 88 between the cap 82 and the upper Ren end of the upper shaft part 70, that is included in the head part 23 of the support element and this allows a pendulum movement in all directions.

The bevel gear 74 is in engagement with a driving bevel gear 90 which sits at the end of a drive pin 91 which is inserted into the upper shaft part 70 and is mounted in a guide plate 92 which is fastened to the outer wall of the upper shaft part 70. At its free end, the drive pin 91 has a polygonal head 93, on which it can be rotated with a turning tool, not shown in detail.

When the screw spindle 75 is rotated via the bevel gears 74 and 90 with the aid of the drive pin 91, it screws into the spindle nut 72 and thereby moves the lower shaft part 71 up or down depending on the direction of rotation, as a result of which the rail 14 is raised or lowered and thereby can be set precisely in their altitude.

The caps 82 of the support elements 21 for the first rail 13 can be connected to the caps 82 of the support elements 22 assigned to them in each case for the second rail 14 by a connecting rod 43 or consist of one piece with such a connecting rod. Furthermore, each cap 82 has a lateral upstand 94 with a tensioning device 95, on which the outer rail foot edge 96 is supported and with which the rail can be pressed against its inner fastening elements (not shown in FIG. 4) in order to switch off the bearing play.

The straightening table 12 mentioned above can be equipped with the support elements shown in FIGS. 2 and 3 or with the support elements shown in FIGS. 4 and 5 and is used not only for height adjustment, but also for side alignment of the track and at the same time stabilizes the support elements of each support yoke.

Turning now to FIGS. 1 and 6, it can be seen that the support elements 21 and 22, which are designed as pendulum supports 30, are part of the straightening harness, which also includes a connecting element 39, two rail foot clamps 40 and 41 and a length-adjustable pull / push element 42. In the exemplary embodiment shown, the connecting element 39 is a connecting rod 43 which rests on the rail feet 20 of the rails 13 and 14 with cranks 44 and 45 at their rod ends 43a and 43b. The rail foot clamps 40 and 41 are hooked into the cranks 44 and 45 of the connecting rod 43 and each comprise a rail foot 20 of the rails 13 and 14 on the underside, while at the same time receiving pins 46 which are on the front and rear of the head parts 23 of the support elements 21 and 22 are arranged.

The rail foot clamps 40 and 41 surround the head parts at a distance and have clamping devices 47 which can be actuated on one or both sides from the outside and press on the outer edge of the respective rail foot 20. If the tensioning devices 47 are tightened, they press the two rails 13 and 14 inwards against the inner ribs 18 of the rib plates 17, so that a play in movement between this rail fastening means 18 and the edge 48 of the rail foot 20 facing it is eliminated.

It can be seen from FIG. 4 that there is play between the pin 46 and the rail foot clamps 40 and 41 even in their assembled, tensioned state, which allows the head part 23 to roll under the rail foot 20.

When tightening, the rail foot brackets 40 and 41 are supported on the connecting rod 43, behind the crankings 44 and 45 of which they are suspended.

It is seen that the distance a of Verkröpfungen 44 and 45 of the connecting rod 43 is slightly smaller than the distance between the inner ^'b rail fastening means 18 to the fin plates 17 of the two rails. As a result, the rail feet 20 of both rails can be pressed firmly against the inner ribs 18 with the clamping devices 47 of the rail foot clamps 40 and 41. The above-mentioned length-adjustable tension / compression element 42 is used to stiffen the support yoke formed by the support elements 21 and 22, the connecting rod 43 and the rail foot clamps 40 and 41 and to align the track to the side an ankle 51 is hinged to the foot part 26 of the support element 22 for the second rail 14. A threaded rod 52 is screwed into the sleeve 49, which carries a polygonal head 53 at its free end and is rotatably and pivotably mounted with a ball head joint 54 in a ball socket 55, which is welded to the rail foot clamp 40. The threaded rod 52 is supported with an inner collar 56 and an outer collar 57 on the ball socket 55, and between the collars and the ball socket can also be arranged disc springs, not shown here, which tightly fit the collars in any angular position of the threaded rod 52 ensure.

It can be seen from Fig. 4 that the threaded rod 52 passes through the head part 23 of the support element 21 with ample play, so that the pendulum support can pivot when the rail 13 moves laterally during side straightening and the convex head bearing surface 31 rolls under the rail foot 20.

The pull / push element 42 can also be arranged such that it is located laterally next to the support elements 21 and 22. The threaded rod 52 then does not pass through the head part 23 of the one support element 21, but is located next to it. Analogously to this, the lower end of the pull / push element 42 is in this case also laterally fastened to the foot part 26 of the adjacent support element 22. Such an asymmetrical solution has no negative effects on the forces acting in the straightening tableware, but there are significant advantages for the storage and assembly of the straightening tableware, since with such an asymmetrical design the support elements can be folded completely inwards and then one to the connecting element 39 take parallel position. In order to align the track laterally, the threaded rod 52 is rotated on its polygonal head 53 and, depending on the direction of rotation, screwed or unscrewed into the threaded sleeve 49. When screwing in, the distance between the ball socket 55 and the ankle 51 shortens. Since the foot part 26 of the right support element for the second rail 14 is firmly connected to the support plate 10 by the coupling element 35 and cannot deflect laterally, the ball joint 54 of the pull / pressure element 42 firmly connected rail foot bracket 40 in Fig. 1 moved to the right. At the same time, the rail 13 firmly clamped therein and the second rail 14 firmly connected to it by the connecting rod 43 and the rail foot clamp 41 also move to the right, while the pendulum supports 30 pivot on their foot bearing surfaces.

It can be seen that the track, together with all parts belonging to it, such as sleepers and rail fasteners, can be easily and laterally adjusted without play. This adjustment can be effected by hand or from a track straightening machine, which reaches the laterally protruding polygonal head 53 of the threaded rod 52 as easily as the screw heads of the tension spindle 28 for the height adjustment and for the clamping devices of the foot clamps.

In the lateral direction of the track, the pull / push element 42 serves as a stiffening diagonal for the support yoke, which holds the track in its correct, vertical position with its height-adjustable support elements 21 and 22.

Immediately before the sleepers 16 of the track 11 are firmly connected to the support plates 10 and, for example, concreted in the support plate trough, the straightening harnesses 12 are removed. This is done by first retracting the support elements 21 and 22 to their shortest length, with their foot parts 26 lifting off from the support plate 10. Since all parts of the support elements are captively connected to one another and the support elements with their pins 46 in the rail foot clamps 40 and 41 hang, they can now be folded inwards by screwing the threaded rod 52 completely into the threaded sleeve 49, the pull / push element 42 reaching approximately a horizontal position approximately parallel to the connecting rod 43. In order to enable the support elements 21 and 22 to pivot, the tensioning devices 47 of the rail foot clamps 40 and 41 are released beforehand, which, as a result, can pivot downward with their suspended part in the cranks 44 and 45.

Since all the individual parts of the straightening harness 12, namely the threaded rod 43, the rail foot brackets 40 and 41, the support elements 21 and 22 and the length-adjustable tension / compression element 42 are connected, the straightening harness 12 is still in the folded state with the cranks 44 and 45 of the connecting rod 43 carried by the rail feet 20 of both rails 13 and 14. It can then be easily removed with a suitable hoist attached to the straightening machine or on a track undercarriage or by hand and prepared for the next use.

7, 8 and 9 show another embodiment of the invention, in which separate units are used for the vertical alignment of the track 11 and for its lateral alignment. Here, the support and height adjustment device again consists of support elements 21 and 22 of the type shown in FIGS. 1 to 5, two support elements at the head and at the foot being stiffened by a diagonal stiffening element 58. In this embodiment, the function of the connecting elements is assumed by the sleepers 16, on which the rails 13 and 14 are fastened with rail fastening means, not shown here.

For side alignment and support of the track, length-adjustable pressure elements 59 are provided on both sides, which are supported on the one hand on an abutment 60 arranged on the support plate 10 and on the other hand with a claw 61 on an edge 62 of the rail foot 20. In the exemplary embodiment shown in FIG. 7, the abutment 60 is formed by one of the side cheeks of the support plate 10 and the edge 62 on which the claw 61 of the pressure element 59 is supported is the outer edge of the rail foot 20.

The pressure elements 59 are arranged between the sleepers. They could therefore also be longer and, for example, be supported with their foot end in a corner 63 between the base plate 10 and the cheek 60 of the support plate and extend under the adjacent rail to the opposite rail, where the claw 61 then lies on the inner edge of the rail foot can support.

The design of the pressure elements 59 is shown in more detail in FIGS. 8 and 9. It can be seen here that the pressure element essentially consists of a screw 64, which has a polygonal head

65 and on a part projecting above this head 65

66 carries the claw 61 mentioned above, with which the pressure element 59 can be hung on the edge of the rail foot. The rear, free end 64a of the screw 64 is screwed into a polygonal nut which is welded into a sheet metal sleeve 67 which is supported on the abutment 60 of the support plate 10. The sheet metal sleeve 67 can be a closed tube, but it can also be a folded sheet that forms a support body that is open at the top.

It can be seen that the pressure elements 59 can either be arranged opposite one another or alternately from one sleeper compartment to the left and right on the track. The manufacture, the attachment of the pressure elements to the track and their dismantling are particularly easy. However, in contrast to the one described above, the device consists of more different individual parts, each of which must be installed and removed individually.

The invention is not limited to the exemplary embodiments shown and described, but several changes and additions are possible without the scope of the invention leave. For example, the devices for height adjustment could also be designed as scissor lifting devices. It is also possible to set up the support elements without a foot part with a spherical or cylindrical lower shaft end directly on the support plate and to secure them in this with a feather key which engages in a slot arranged in the support plate. Furthermore, the device can also be designed such that the rails are spread outward in their rail fastening means in such a way that the outer edges of the rail feet bear against the outer rail fastening means. It is only important that the movement of the rails in their fasteners is turned off during the lateral alignment.
