Abstract

In a set of rail points, running rails (2) and wing rails (3) are fastened to a concrete sleeper (5) on which a switching device (11) is arranged for switching a movable switch diamond (4). The concrete sleeper (5) has a cuboid geometry with an upper side (17), chamfered longitudinal edges bounding the upper side and side faces (18) extending from the longitudinal edges. The switching device (11) is fastened on the upper side (17) of the concrete sleeper (5) between a running rail (2) and a wing rail (3), wherein the drive equipment (7) is arranged outside the running rails (2), preferably connected to the concrete sleeper (5). The drive equipment (7) is connected to the switching device (11) by at least one line (12) running along the chamfered longitudinal edges, wherein the switching device (11), the at least one line (12) and, where appropriate, the drive equipment (7) run within the sleeper width.

Description

Switch for rails

The invention relates to a switch comprising travel rails, wing rails and a frog with frog point reciprocable between the wing rails, wherein the rails and the wing rails are mounted on a threshold on which an adjusting device for adjusting the frog point is arranged, which via at least one line is connected to a drive device.

To adjust tongue rails relative to rails between an abutment position and a storage position, adjusting devices are required, which are connected via a connecting rod with the tongue rails. Adjustments are also required for switches with a centerpiece with movable frog tip for the conversion of the frog point between the two wing rails. In both cases, the actuator and linkage are typically between two thresholds, i. arranged in the so-called threshold compartment or in a hollow trough sleeper, in which also a drive device, such as e.g. a hydraulic drive can be located. The arrangement of an adjusting device for a movable frog point together with connecting linkage in the sleeper compartment or in a trough sleeper is described, for example, in EP 343150 A2.

The disadvantage here is that trough sleepers require special provisions in the field of bulkhead installation, since trough sleepers must generally be used deeper than standard sleepers. Consequently, a separate extraction of the bulkhead at the installation site is required.

CONFIRMATION COPY In the switch known from DE 202010008526 Ul, it is possible to fix the adjusting device and the linkage for the conversion of the tongue rails on a standard concrete sleeper without the threshold being surmounted in width. This avoids the installation of trough sleepers.

The present invention now aims to adapt to the type described in DE 202010008526 Ul for the conversion of the movable frog tip, with no structural changes in the overall structure of the switch should be required.

To solve this problem, the switch of the type mentioned is inventively developed such that the threshold is a concrete sleeper cuboid geometry with an upper side, the top limiting beveled longitudinal edges and outgoing from the longitudinal edges side surfaces, that the actuating device at the top of the threshold between a Ride rail and a wing rail is fixed, that the drive device is arranged outside the rails and preferably connected to the threshold that the at least one connecting the drive device with the actuator line along the slanted longitudinal edges, wherein the adjusting device, the at least one line and possibly the drive device extend within the threshold width.

According to the invention, therefore, a conventional concrete sleeper, in particular a standard concrete sleeper, is used for fastening the drive and adjusting devices, wherein the components required for actuating the movable frog tip extend within the threshold width, ie in particular within an envelope, laterally of the concrete sleeper side surfaces or whose extensions are limited. Thus, no elements are present laterally beyond the threshold, so that a plug in the switch area can be done equally as in the track itself. Furthermore, there is the advantage that the structure is homogeneous, ie the thresholds remain the same throughout in the turnout area, regardless of whether a drive for a movable core is provided or not. The arrangement of the adjusting device, the at least one line and possibly the drive device within the threshold width here means preferably that the units in the normal projection do not protrude over the widest measure of the threshold.

The invention allows a simple installation of the switch, as no special precautions in the field of bulkhead installation are necessary, as is the case with steel trough sleepers, which must be used in principle deeper than standard sleepers. Furthermore, there are identical rail bearings and rail fastenings as in sleepers that have no points drive.

The drive device, which is designed in particular as a hydraulic unit, is preferably connected to the concrete sleeper in an end region of the sleeper outside the rails, wherein a bracket may extend from the sleeper that extends beyond the front side of the concrete sleeper, thus providing sufficient space for securing the drive device to make available. Regardless of this, however, the width extension of the holder and the drive device is preferably selected so that they are basically within the width of the concrete sleeper. In this case, the assembly height of both the adjusting device and the drive device is preferably selected so that a collision with the clearance gauge is excluded. If, as corresponds to a preferred embodiment, the drive device is designed as a hydraulic unit, it is hydraulically connected via the at least one designed as a hydraulic line line with the adjusting device.

In an advantageous manner. Way, not only the hydraulic lines within the width of the concrete sleeper are arranged, but also the linkage connecting the actuator and the movable frog point. If necessary, the connection linkage emanating from the setting device also comprises, in addition to a control rod which is responsible for the changeover of the movable frog tip, also a tester rod for a final-position checking device. In order to accomplish the arrangement of the connecting linkage within the threshold width in a simple manner, a preferred embodiment of the invention provides that the adjusting rod and possibly the Prüferstange are passed below the rail foot of a wing rail. In particular, it can be provided in this context that the wing rail is formed with a reduced height relative to the frog tip and that the control rod and possibly the Prüferstange are passed through a space between the rail of the wing rail and the top of the threshold. The control rod and possibly the Prüferstange can be made straight here, i. without cranking, resulting in an optimal power flow. In this case, the adjusting rod and optionally the Prüferstange preferably engage the rail of the frog tip.

So that relative displacements of the movable frog point relative to the adjusting device carrying threshold do not lead to the initiation of undesirable forces on the control rod and the actuator, provides a preferred embodiment that the control rod and possibly the Prüferstange each about a pivot mechanism permitting at least two-axis pivoting movement, in particular a ball joint, are articulated on the adjusting device. Furthermore, it can be provided that the control rod and possibly the Prüferstange are each articulated about a vertical pivot axis pivotally mounted on the rail of the movable frog point.

The connection of the linkage with the frog point is structurally in a particularly simple manner in that the control rod and possibly the Prüferstange attack over a rail foot engaging around the clevis on the movable frog point.

An improved stability of the frog point is preferably ensured by the fact that the wing rails are formed with an asymmetric tongue rail profile.

Preferably, the adjusting device, the wing rails and the frog point are not directly on the concrete sleeper, but on a base plate, which is optionally arranged with the interposition of an elastic base plate on the concrete sleeper. In particular, the movable frog point is slidably mounted on the arranged on the threshold base plate, so that this base plate acts as a sliding chair for the frog point.

The base plate is preferably connected via at least one screwed into a recess of the concrete sleeper fastener with the concrete sleeper, wherein the adjusting device is connected to the concrete sleeper on the at least one fastener. However, this does not exclude that further fastening elements are provided, which may be screwed into separate bores to be introduced, which are go out side of the concrete threshold. Thus, not only can the actuator be connected to it without altering the concrete sleeper shape, but in addition, existing holes in the concrete sleeper can be used to secure the actuator.

The preferably provided space between the concrete sleeper and the underside of the rail foot of the wing rails is achieved in a structurally advantageous and space-saving manner, that on the base plate a rail chair for supporting the wing ^; rails fastened, in particular welded. The width of the rail chair preferably corresponds to at most half the width of the threshold, so that the control rod and possibly the Prüferstange can be guided laterally of the rail chair.

On rail chair preferably resort to means for low voltage and lateral support of the wing rails.

Fig. 11 is a representation according to FIG. 8 with a further modified embodiment of the attachment of the linkage at the frog tip.

In Fig. 1, a section of a switch 1 is shown comprising rails 2 and a centerpiece with a movable, between the two wing rails 3 back and forth movable frog tip 4. The rails 2 and the wing rails 3 are mounted on a plurality of concrete sleepers 5. The mounting of the rails 2 is carried out via attached to concrete sleepers 5 mounting plates 6 and conventional, the rail of the rail 2 low-voltage rail fastening means.

To convert the movable frog tip 4 designed as a hydraulic unit drive unit 7 is provided, which is fixed outside of the rails 2 at the threshold 5. The attachment is shown more clearly in Fig. 3, wherein it can be seen that the holder or the frame from which the drive means 7 emanates, extending along the top of the threshold 5 extending plate-shaped base portion 8 extending over the end face 9 of Concrete threshold 5 also extends outside of the concrete sleeper 5 extend from the region of the base portion 8 angled leg 10, which are supported with their transverse edges on the end face 9 of the concrete sleeper 5, so that a sufficient stability is given. Instead of an extension of the bracket the drive device 7 beyond the end face 9 of the threshold 5 addition, it is also possible to extend a standard threshold, so that a plate is fixed on this in an end region from which the drive means 7 goes out. In this case, it is not absolutely necessary for the plate 8 to project beyond the end face 9 of the threshold 5. The drive unit can also be mounted outside the threshold on a separate base plate.

Between a wing rail 3 and a running rail 2, an adjusting device 11 is attached to the top of the threshold 5, which is hydraulically connected via lines 12 to the drive means 7. In the adjusting device 11 of the drive unit 7 made available hydraulic pressure is converted, for example by means of a hydraulic cylinder piston unit in an actuating movement in the direction of the double arrow 13. From the adjusting device 11 is an adjusting rod 15, which engages the rail of the movable core 4, in order to move the movable core 4 in the direction of the double arrow 13 back and forth. The adjusting ^device 11 may have, in addition to the points drive, an integrated point locking device and a separate end position checking device. The switch lock serves to fix the movable frog point 4 in its respective end position. The Endlagenprüfeinrichtung serves to mechanically scan the current state of the movable frog point 4 and to generate a test signal, can be reliably determined by means of whether the movable heart ^¬ tip 4 was changed correctly and whether the movable frog tip 4 is in its respective correct end position , The Endlagenprüfeinrichtung has for this purpose a Prüferstange 14, which extends substantially transversely to the rail longitudinal direction and which during conversion of the movable core 4 is moved in the longitudinal direction of the rod. The position of the Prüferstange 14 is detected in the adjusting device 11 by means of electromechanical transducers, for example in the form of limit switches or Tongue contact.

In the sectional view of FIG. 2, the cross section of the concrete sleeper 5 is shown schematically, and it can be seen how the hydraulic lines 12 are arranged and below the running rail 2 can be passed. The concrete sleeper 5 has a cuboid or block geometry with bevelled, ie beveled upper longitudinal edges 16 which laterally delimit the upper side 17 of the concrete sleeper 5 and the other side surfaces 18 thereof. At the top 17 of the concrete sleeper, the driving rail, not shown in Fig. 2 for the sake of clarity, is attached. The hydraulic lines 12 extend along the chamfered longitudinal edges 16 of the concrete sleeper 5, so that they can be guided on the one hand below the rail foot of the running rail 2, but on the other side not protrude beyond the width B of the concrete sleeper 5.

In Fig. 1 it is seen that the drive unit 7 and the adjusting device 11 have a width such that the width B of the concrete sleeper 5 is not exceeded.

In the side view of FIG. 3 it can be seen that the wing rails 3 and the movable core 4 are mounted on a base plate 19, wherein the wing rails 3 are formed with respect to the movable frog tip 4 reduced height and are each supported on a rail chair 20. On the rail chair 20 in each case lateral supports 21 which engage the wing rails 3 against a butt down. The base plate 19 and the mounting plate 6 of the left in the drawing illustrated rail 2 are each secured by a fastening screw 22 at the threshold 5. With these fastening screws 22, the adjusting device 11 is held at the same time, wherein the adjusting device 11 is bolted to the concrete sleeper 5 via further fastening screws 23. The adjusting device 11 in this case comprises a housing, the respective frontal region is connected via a mounting plate 24 with the concrete sleeper 5, which in turn has mutually offset bottom surfaces, one of which on the top of the threshold 5 and the other on the base plate 19 and Fixing plate 6 rests. Thus, the mounting plate 24 on the bottom side a step whose height is adapted to the base plate 19 and the ribbed plate 6.

In the detailed representation of FIG. 4, the outgoing from the actuator 11 control rod 15 and the Prüferstange 14 is better visible. The connection of the adjusting device 11 with the movable frog point 4 is shown in the detail view of FIG. 5. In Fig. 5, only the control rod 15 is shown. However, the following explanations apply analogously to the Prüferstange 14. The control rod 15 is connected via a ball joint 25 with a direction of the double arrow 13 driven actuator with the adjusting device 11 verbun ^¬ . At the opposite end of the control rod is articulated via a clevis 26 on the rail 27 of the movable core 4. The clevis 26 in this case includes with its fork-shaped end the rail foot 27 of the movable core 4. The articulation of the clevis 26 takes place articulated, where ^{¬ is designated} at the pivot axis with 28. In order to allow the arrangement of the control rod 15 below the wing rails 3, the wing rails 3 a in comparison to the movable Centerpiece 4 lower rail profile, the wing rails 3 are supported on a raised rail chair 20. As can be seen in FIG. 6, the rail chair 20, 20 has a relatively small width, so that the control rod 15 and the tester rod 14 can be guided past the rail chair 20 without projecting beyond the width B of the concrete sleeper 5.

The lateral support of the wing rails 3 takes place by means of supporting elements 21 which are fastened to the rail chair 20. The rail chair 20 has for this purpose lateral recesses 29 which engage over a widened head 30 of a bolt 31. At the free end of the bolt 31, a thread is mounted in each case, can be screwed onto the nuts not shown, to tension the lateral support members 21 against the rail foot 32 of the wing rails 3. The lateral supports 22 are further supported by a plate-shaped element 33 on the web 34 of the wing rails 3, whereby the connection of the plate-shaped element 33 on the web 34 by means of a schematically indicated screw 35 takes place.

5 and 6 is further apparent that the base plate 19 rests with the interposition of an elastic support 36 on the concrete sleeper 5.

In Figs. 7 to 11 modified embodiments are shown, in which the wing rails 3, in contrast to the embodiment according to FIGS. 1 to 6 are not formed with an asymmetric rail profile, but with a thick-rail rail profile. This serves to be able to absorb wheel loads of approx. 40 tons or more, which act directly on the wing rails, better in the area of the frog tip. For equal The parts used in FIGS. 1 to 6 have been retained.

In Fig. 7, a section of the switch in the region of the movable core 4 is shown, it being understood that the lateral supports 21 of the wing rails 3 are not shown. From the adjusting device 11 in turn go from an adjusting rod 15 and a Prüferstange 14, which are attached to the rail 27 of the movable frog tip 4. The control rod 15 and the Prüferstange 14 are passed under the wing rail 3, as better seen in Fig. 8. The wing rails 3 are now carried out with the same profile height as the movable frog point 4, so that the attachment of the control rod 15 and the Prüferstange 14 must be made to the rail 27 of the movable frog tip 4 from below. For the support of the wing rails 3, a simpler (not shown) rail chair 20 is provided in contrast to the embodiment of FIGS. 1 to 6, since the wing rails 3 as well as the movable frog tip 4 rest directly on the base plate 19. The attachment of the control rod 15 and the Prüferstange 14 on the rail 27 by means of a dovetail connection. The underside of the rail foot 27 of the movable frog tip 4 is provided in the region of the connection of the linkage with a dovetail cutout 37, which is positively enclosed by the two-piece connection piece 38 of the control rod 15 and the Prüferstange 14. The two halves of the connecting piece 38 are clamped by a screw from both sides against the dovetail cutout 37. To further stabilize the position of the movable frog point 4 in the respective abutment with the wing rails 3, a lateral milled recess or chamfer 39 is provided on the rail foot of the wing rail 3, which corresponds to the outer contour of the connecting piece 38. As is apparent from Fig. 9, the adjusting rod 15 and the Prüferstange 14 between the top of the threshold 5 and the underside of the rail foot of the wing rails 3 are performed within the height of the base plate 19.

Fig. 10 shows an alternative embodiment of the attachment of the control rod 15 and the Prüferstange 14 at the bottom of the frog point 4 by means of a bolt connection without causing a relevant cross-sectional weakening of the movable Herzstückspit e 4. It is a bolt 40 is provided, which is rotatably passed through a recess of the control rod 15 and the Prüferstange 14 and inserted into a bottom of the movable centerpiece tip 4 introduced blind hole and secured in position by means of screws.

A further design of the coupling of the control rod 15 and the Prüferstange 14 to the movable frog tip 4 without causing a weakening of the moment of inertia of the frog tip is shown in Fig. 11. The control rod 15 and the Prüferstange 14 are performed in the region of the neutral fiber through holes in the rail web of the wing rails 3 and screwed by means of a screwed angle compensation element 41 with the frog point 4.
