Description

The present invention relates to a rail support device having the features of the preamble of claim 1.

Such rail support devices are used to transport railroad tracks on rail transport cars assembled on rail transport trains. In this case, already prepared or prefabricated long rails (these are rail sections of up to several hundred meters in length) are transported, in particular from short rails in a rail welding plant, for example to track construction sites, to be laid there in the track and connected to the rail infrastructure.

In this case, the long rails are typically lined up in several layers on vertically stacked support beams, which extend transversely to a longitudinal direction of the rail transport cars strung. Such rail support devices are for example from the DE 43 12 964 A1 , of the DE 44 18 376 A1 or the DE 20 2004 019 248 U1 known. In the rail support devices known from these publications, however, the rails are exposed in the uppermost layer with their rail heads arranged in the vertical direction and not further secured. Although the rails are arranged there by laterally Secured securing elements against lateral slippage, however, it has been shown that especially for very long rails and long transport distances longitudinal displacements of the long rails arise, which can lead to collisions with buildings on the rail transport car in the worst case, thereby causing damage, repair costs and failures.

Accordingly, a solution has been devised for this problem, being placed under this solution in the core on the uppermost layer of rails arranged on the rails rails a horizontally extending clamping bar and this clamping bar is acted upon by a clamping mechanism in the direction of the rail heads with a pressing force. Thus, designed and operated by the company voestalpine AG from Austria rail transport cars are known and in use, the rail support devices in which in two U-shaped profiled, vertically extending, with the openings of the U-profiles facing each other support beams for the circulation of Rails can be introduced and can be provided with a clamping bar, which is placed on the top layer of the recorded rails and by means of clamping screws, which project through threaded rods, the openings in the outer ends of the clamping bar, and can be pressed against the top rail layer. Such provided with clamping bar rail transport pads are arranged distributed in this concept only at greater distances on the rail transport car, before and behind are rail transport pads without such clamping beams and no jamming of the laid rails so as to allow evasion of the rails in cornering and damage the transported Rails due to high bending moments in the intermediate area to prevent short clamping distances.

Although with this known system jamming of the rails placed on the rail support device and thus a longitudinal displacement of the same can be prevented, this construction is still subject to disadvantages and should be improved. In particular, the handling is the clamping bar, which must be lifted for loading and unloading the rails always from the U-shaped guides of the vertical supports, difficult, requires the use of a crane due to the weight of this clamping bar, which not only at the loading point, but above all also at the unloading point, which is often a construction site located outside the area of larger facilities, must be provided or provided. Furthermore, the fixing and jamming of the clamping bar by means of the screw connections is complex and in turn requires the use of special tools, namely a correspondingly sized mouth or ring wrench for tightening or loosening the nut. In this case, the applied clamping forces can also be set only insufficiently reproducible, which is also considered to be disadvantageous.

The clamping bar in the known, above-described solution has on its side facing the support on the rail heads of the uppermost layer of the recorded in the rail support device rails a wooden board, with which it rests on the rail heads. It can be observed that on the one hand by given due to manufacturing tolerances different dimensions of the rails (especially in the rail height, measured from the level of the rail foot to the level of the rail head), on the other hand by inaccurate shaping of the wooden board on the side by side in the uppermost layer of the rails In the rail support device recorded rails different pressure forces are exercised. In this case, it may even happen that, despite a distortion of the clamping bar against the top rail position individual rails experience little or even no significant pressure, so not, as desired, be securely fixed by the clamping bar. Here, too, there is a need for improvement.

Another rail support device with supports (102,104), basic threshold (2a), clamping bar (26), clamping mechanism (4), bearing surface (58) of the clamping bar (26) displaceable relative to a body of the clamping bar (26) in the vertical direction, and means Actuator (70) is actively fed towards the rail support surface, is from the JP 2000 108 896 A known. Accordingly, it is an object of the present invention, a rail support device of the type mentioned above, which has a clamping bar in combination with a clamping mechanism for applying a clamping force on the uppermost layer of rails in the rail support device to specify that is simplified in handling and has improved reliability in terms of clamping action.

This object is achieved by a rail support device with the features of claim 1. Advantageous developments of such a rail support device according to the invention are specified in the dependent claims 2 to 14 and described in more detail.

According to the invention, the novel rail support device thus - this first in accordance with the prior art - two opposing, a support area laterally bounding vertical supports, extending in a vertically lower portion between the supports basic threshold, on a top a rail support surface for the Shutdown of rails defines a horizontal bar arranged above the base, which is mountable on a bottom surface of a bearing surface for engaging rail heads of a layer of rails deposited on the rail support device, and a tensioning mechanism for applying vertically between the base rail and the clamping bar acting clamping force.

The novel rail support device now differs from the known prior art in that the rail support surface is displaceable relative to a body of the basic threshold in the vertical direction and that the bearing surface is displaceable relative to a body of the clamping bar in the vertical direction, wherein one of said surfaces, ie the rail support surface or the bearing surface, by means of a drive active in the direction of the other surface, ie the bearing surface or the rail support surface, can be fed and wherein the other surface, ie the bearing surface or the rail support surface, via an elastic return means in the direction of the one by means of the drive actively in the direction of the other surface deliverable surface, ie the rail support surface or the bearing surface, is biased.

• So kann ein entsprechender Antrieb insbesondere so ausgestaltet werden, dass er ohne ein mitzuführendes Werkzeug betätigt werden kann. Desweiteren wird durch die Kombination aus einem aktiven Zustellen einer der Flächen Lagerfläche bzw. Schienenauflagefläche und das passive Auslösen einer Gegenkraft durch das elastische Rückstellmittel, welches die andere Fläche, Lagerfläche bzw. Schienenauflagefläche in einer Klemmrichtung vorspannt, ein vergleichmäßigter und verbessert wirkender Eintrag der Klemmkraft erzielt. Dabei kann der Antrieb vorteilhafterweise auch derart gestaltet sein, dass er eine reproduzierbare Aufbringung einer wählbaren Klemmkraft erlaubt, kann beispielsweise mit einer eine die Klemmkraft repräsentierenden Stellgröße anzeigenden und oder einhaltenden Einrichtung versehen sein, zum Beispiel im Hinblick auf die Stromaufnahme eines durch einen Elektromotor angetrieben Stellantriebes oder durch den Druck eines hydraulisch oder pneumatisch betätigten Stellantriebes.

By this invention innovation and structural transformation over the prior art, various advantages are realized:

• Thus, a corresponding drive can in particular be designed such that it can be actuated without a tool to be guided. Furthermore, by the combination of an active infeed one of the surfaces bearing surface or rail support surface and the passive release of a counterforce by the elastic return means which biases the other surface, bearing surface or rail support surface in a clamping direction, a more equal and improved acting entry of the clamping force achieved , In this case, the drive can advantageously also be designed such that it allows a reproducible application of a selectable clamping force, for example, be provided with a the clamping force representing a control variable indicating and / or maintaining device, for example with regard to the current consumption of an actuator driven by an electric motor or by the pressure of a hydraulically or pneumatically actuated actuator.

Advantageously, the drive is a hydraulically operated drive. A hydraulically actuated drive has the advantage that large forces can be generated and transmitted with it. At the same time, what is provided according to a further advantageous development of the invention can be designed as a manually operated drive, if it has, for example, a hydraulic hand pump. This form of design of the drive allows training without the need of supplying a power supply from outside, such as a power supply, so that the rail support device according to the invention can ultimately be designed and formed as a self-sufficient unit.

The elastic return means may advantageously comprise spring packs which are arranged between the surface provided with the elastic return means, that is to say the bearing surface or the rail support surface, and a housing in which this surface can be displaced in the vertical direction. Deartige spring packages can be structurally comparatively easy to implement, they can be formed, for example, as a cup spring packages. Due to the design with several such spring assemblies, in particular in the element in which they are installed (basic threshold or clamping bar) in the respective longitudinal direction of this element, ie in the direction in which the vertical supports face each other, can be arranged one behind the other at different positions, a very targeted distribution of the clamping force can be achieved. By an individual design and selection of the spring force of the individual spring assemblies can even be influenced on a clamping force profile to thereby make appropriate adjustments to the required clamping force to the required with regard to the horizontal and lateral positioning of the rails position.

According to a further advantageous embodiment of the invention may be provided in the rail support device according to the invention in the vertical direction between the base and the clamping bar at least one displaceable on the supports in the vertical direction festlegbarer, extending in the horizontal direction support beams on a bottom a pressure surface for placement on rail heads From below the support beam arranged rails and on a top surface has a bearing surface for the parking of rails mounted on the support beam. Such a support beam allows the inclusion of rails in the rail support device in a further vertical stack level, so that a correspondingly larger number of rails can be stored on the rail support device. It is important that the support beam on the supports in the vertical direction can be fixed displaced. Because so if, by means of the vertically displaceable surfaces rail support surface and bearing actuator and the actuator comprehensive clamping mechanism between the clamping bar and the base threshold, a clamping force is applied, applied to the superimposed planes of the applied rails and transmitted vertically on and on supporting beams. In particular, more than one such support beam, for example, two such support beams may be provided so that even more vertically stacked layers of rails can be stacked for transport, in two support beams so according to three rail layers. It should be emphasized that, even with a plurality of such support beams, it is crucial that all support beams are fixed vertically displaceable on the supports, so that the applied clamping force can act on all layers of the vertical rails arranged one above the other. Clamp the stringers in each case with the pressure surface, the lower layer of rails by applying the clamping force or by forwarding the clamping force on the rail heads this position and with the support surface, the upper layer rails from the rail foot side.

Advantageously, the one or the plurality of support beams can be fixed to one of the supports pivotable about its vertical axis. Such a construction allows the support beams, which in this embodiment may also be referred to as "rotation thresholds", not to have to be lifted altogether from the vertically extending supports in order to load or unload rails onto the rail support device. Rather, the support beams can simply be pivoted about the vertical axis of the support on which they are pivotally mounted, and so are brought out of the overlap with the rails or with the surface provided for the support of the rails, so that the rail support device loading or can be unloaded. It can be provided on the support to which the support beam is pivotable about the vertical axis and displaceable on the support in the vertical direction, Tragbalkenhubmittel provided at a pivotal movement of the support beam about the longitudinal axis of the support on which it is pivotally mounted, a effect vertical displacement of the supporting beam. In this way, when lifting the support beam at the same time a lifting of the rail position, on which this rests with the pressure surface, causes, so that this lifting is not accomplished by manually lifting the support beam, but at the same time takes place with the pivoting movement. Here, for example, a slotted guide (or a pivot bearing with such a slotted guide) may be formed, as you in the DE202004019248U1 described and disclosed.

Furthermore, if the rail support device according to the invention provides at least one support beam, the pressure surface and / or the bearing surface of this support beam can be provided with an elastic support. Such an elastic support may for example be a hard rubber mat, which is applied to the corresponding surface or introduced into this. Such elastic pad can advantageously a more advanced and even improved Fixing cause the applied to the respective surface rails by deformed by the elastic deformation of the support the pressure surface or the bearing surface due to the force applied by the actuator clamping force and thus any occurring due to tolerances in the rail dimensions height differences are compensated, so that is ensured in that all rails are detected with a corresponding clamping effect.

Advantageously, according to a further development of the invention, the clamping bar can be fixed to one of the supports so as to be pivotable about its longitudinal axis. Similar as described above in connection with the optional support beams to be provided, also in connection with the clamping bar such a solution has the advantage that the clamping bar does not have to be lifted off the vertical supports as a whole. Rather, it is sufficient to pivot the clamping bar with less effort and thus release rails arranged thereunder or a surface for the support of rails. Advantageously, it can be provided that the clamping bar is fixed to the support not only pivotable about its vertical axis, but continue to be displaced in the vertical direction. Thus, the clamping bar for the training of the pressing force or clamping force can be adjusted accordingly in height. At the same time, the clamping bar can also be lifted off the rail position on which it rests when pivoting. This lift-off can be assisted, as described above with respect to the optional support beams, by clamping bar lifting means which cause vertical displacement of the clamping bar upon pivotal movement of the clamping bar about the vertical axis of the support on which the clamping bar is pivotally mounted. Again, a slide guide can be chosen with advantage, as this example, in the DE 20 2004 019 248 U1 described and disclosed.

Further advantages are provided by a further development of the rail support device, in which the rail support surface of the base sleeper and / or the bearing surface of the clamping beam is / are provided with an elastic support. Such an elastic support can in turn be applied to the bearing surface or on the rail support surface or embedded in the surface in question. She can turn For example, have the shape of a hard rubber mat. Such an elastic support results in the manner already described above with reference to the analog, for the optionally provided support beam as a design option possible elastic support the advantage of a secured rail for all clamping action by compensating given for example by manufacturing tolerances height differences within rail layers.

In a further development it is provided that the rail support device of the invention may have a mechanical locking means, which causes the releasable blocking of the delivered with the actuator surface (ie the rail support surface or the bearing surface) in a set by means of the actuator vertical position. Such a mechanical locking means can advantageously when the required or desired clamping force is applied by means of the actuator, block or set the actively moving surface with the actuator in position, so that the actuator can be switched off and not during a period of use, for Example during a transport journey to transport rails, must be kept active to apply or maintain the nuclear power active. If the clamping action is then to be canceled in order to release rails arranged on the rail support device and clamped therein, the blocking means is released and moved from a blocking position into a release position. To release the blocking agent, for example, the actuator can be activated to relieve the blocking agent by applying a clamping force and to allow a displacement thereof in the release position. The actuator is thus equally provided by such a blocking means with a self-locking, which also holds the once occupied position of the positioned with the actuator element when the actuator is switched powerless.

The rail support device according to the invention can in a further advantageous constructive development, in which the clamping bar is arranged to be displaceable on the vertical supports in the vertical direction, on the vertical supports abutment elements, which are arranged above the clamping bar are and which are adjustable in height in the longitudinal direction of the supports. This type of configuration allows adjustment of the vertical height position of the clamping bar to adapt to the stacking height of the recorded in the rail support device rails. Such abutment elements can be formed, for example, by an advantageous halbhalfweise secured with lock nuts, screw sleeve, which form a corresponding abutment surface on their the clamping bar surface facing. In this case, over the abutment surfaces in the direction of the clamping bar above, for example, cylindrical holding portions may be formed, which have a larger diameter than a stop portion of the supports, so that the clamping bar with an open, annular receiving area having a more than 180 ° circumferential enclosure and an opening width which is larger than the diameter of the abutment portion of the supports in the abutment portion placed over the support and then by positively advancing such an abutment member in a manner that the cylindrical holding portion enters into the annular receiving area, can be positively locked.

Advantageously, in the rail support device according to the invention, the rail support surface in the basic threshold be that which can be actively fed by means of the drive in the direction of the bearing surface, whereas the bearing surface is biased in the clamping bar via the elastic return means in the direction of the rail support surface. Such a solution has therefore proved to be advantageous, since the clamping bar always has to be moved and relocated for loading or unloading of the rail support device, whereas the basic threshold is constantly stationary. In a stationary arranged element, the actuator can be integrated easily and with less design effort.

In the figures, an embodiment of an inventively designed rail support device is shown and shown in different views. This embodiment will be described below with reference to the figures. It should be emphasized that the figures do not represent complete design drawings, but rather represent largely schematic illustrations of the elements essential to the invention and further advantageous embodiments and features.

A rail support device according to the invention is generally designated by the reference numeral 1 in the figures. It contains as essential elements two mutually opposite spaced apart, with their longitudinal direction vertically extending supports 2 and 3 and a horizontally extending, the distance between the supports 2, 3 in a lower portion of the rail support device 1 bridging basic threshold 4th In the basic threshold a rail support surface 5 is formed, which is displaceable relative to a body 6 of the base threshold 4 in the vertical direction.

Vertically above the base threshold 6 is a clamping bar 7 can be seen in the FIGS. 1 . 2 . 8th and 13 in a distance between the supports 2 and 3 bridging, shown at two supports 2, 3 position is shown. This Clamping bar 7 has on a bottom of the base 6 facing a bearing surface 8, which rests in operation of the rail support device 1 with rails arranged thereon on rail heads of an uppermost layer of rails. This bearing surface 8 is displaceable relative to a body 9 of the clamping bar 7 in the vertical direction.

The clamping bar 7 itself is pivotally mounted on the vertical support 2 and also displaceable in the vertical direction with a circular cross-section support 2 embracing, integrally formed on the clamping bar 7 bearing sleeve 10. With a partially formed in cross-section retaining claw 11 engages in the in FIGS. 1 . 2 . 8th and 13 shown position of the clamping bar 7, the vertical support 3. In this case, the clamping bar 7 from the in the FIGS. 1 . 2 . 8th and 13 shown position to release the underlying area around the support 2 are given away. When pivoting the clamping bar 7 then releases the retaining claw 11 of the support 3, the bearing sleeve 10 of course remains connected to the support 2. In such a pivoting movement in a in the representation of FIG. 1 forward movement directed to the right, runs on a bottom of the bearing sleeve 10 formed slide track 12 via a fixed to the support 2 rolling pin 13, which is triggered by the interaction of rolling pin 13 and slide track 12 by the pivoting movement at the same time a lifting movement in the vertical direction. In order to easily pivot the clamping bar 7, a handle 14 is formed on this. A representation of the position in which the clamping bar 7 is pivoted into an open position, is in Fig. 14 shown. In this position, the clamping bar 7 is placed on a formed on a storage support 47 pad 48, so that the bearing sleeve 10 does not permanently bear the weight of the support bar 7 at the end of a one-armed lever.

On the vertical supports 2 and 3 are arranged above the clamping bar 7 in the vertical direction displaceable abutment elements in the form of threaded sleeves 15 and 16 with it formed respectively, annularly projecting stop collar 17. In the stop collar 17 openings 18 are peripherally introduced, which serve as a tool approach to a tool for screwing to attach the screw sleeves 15 and 16 can. In particular FIG. 5 can be seen, the retaining claw 11 is provided with a part-annular recess 19 whose circumferential extent is over 180 °. Via an access opening 20, an abutment portion of the support 3, whose diameter is selected so that it can be performed through the access opening 20, are introduced into the recess 19. The threaded sleeve 16 has a reduced in diameter relative to the diameter of the stop collar 17, down over the stop collar 17 projecting cylindrical extension 43 (see Fig. 12 ), which is formed in its diameter corresponding to the diameter of the part-annular recess 19, so that this extension can be introduced into the recess 19 from above. By a corresponding displacement of the screw 16 in the vertical direction downwards by screwing them so this cylindrical extension 43 can be introduced into the recess 19 and then locked due to the over 180 ° encompassing coverage of the recess 19, the retaining claw 11 form-fitting manner.

In the vertical region between the base sill 4 and the clamping bar 7, two supporting beams 21 are arranged in this embodiment. These each have a bearing surface 22 on its upper side, can be placed on the rails with their rail feet. On their underside, the support beams 21 each have a pressure surface 23, with which they rest on rail heads of a arranged below the respective support beam 21 rail position. The support beams 21 are arranged in a similar manner to the support 2 pivotable and vertically displaceable as the clamping bar 7. The support beams 21 each have a bearing sleeve 24 which encloses the circular cross-section support 2. At the support 3, the support beams 21 in the in the FIGS. 1 . 2 . 8th and 13 shown position releasably fixed by means of locking elements 25. Even when pivoting the supporting beam 21 results in a sliding guide a simultaneous vertical lifting. Also, the bearing sleeves 24 of the support beams 21 have on their respective underside a slide track 26 which cooperates with a corresponding, fixed to the support 2 rolling pin 27. The pivoted in an open position positions of the support beams 21 are in Fig. 14 to recognize. The support beams 21 are stored on supports 48 of the storage support 47.

For secure clamping of recorded in the rail support device 1 rails now a vertically acting clamping force is applied to the rails by means of a clamping mechanism. This clamping mechanism comprises the vertically displaceable rail support surface 5, an actuator to be explained in more detail below for active vertical displacement of the rail support surface 5 in the direction of the clamping bar 7, the bearing surface 8 and an elastic return means which the bearing surface 8 in the direction of the base threshold 4 in the vertical direction biases.

The elastic return means consists in this embodiment, in particular FIG. 4 can be seen from a number of longitudinally of the clamping bar 7 successively arranged spring assemblies 28, which exert a correspondingly elastic restoring force on the bearing surface 8. These spring assemblies 28 each have a plurality of disc springs 29, which are arranged one above the other to the spring assemblies 28 are connected. In FIG. 7 is shown in enlarged detail representation of such a spring assembly 28 again in more detail. It is formed by the superimposed and placed over a pin 30 plate springs 29 and placed on the disc springs 29, serving as a stop guide bush 31 which is fixed with a castle nut 32 which is screwed onto the bolt 30 and held in position. The individual spring assemblies 28 can be adjusted in the longitudinal direction of the clamping bar 7 with different spring force, so as to form a restoring force profile.

The rail support surface 5 is by means of a hand pump 44 (see Fig. 13 ) operated hydraulic drive in the vertical direction relative to the body 6 of the basic threshold 4 displaced. A hydraulic fluid reservoir and the hand pump 44 are located in a closable with a door 33 device box 34. Via a valve 49, the flow rate of the hydraulic fluid can be regulated.

By pressing the hand pump 44, the hydraulic fluid is pressurized and arranged via hydraulic lines 45 in the body 6, on the rail support surface 5 acting hydraulic pressure rams 46 supplied. About the hydraulic pressure ram 46, the rail support surface 5 is displaced relative to the body 6 of the base threshold 4 in the vertical direction, namely issued upwards in the direction of the clamping bar 7.

Now, if the rail support device 1 is completely equipped with the male rails, ie rails are received both on the rail support surface 5 of the base threshold 4 and on the support surfaces 22 of the support beam 21, the clamping bar 7 is placed and placed on the rail heads of the top rail layer. The positions of the supporting beams 21 and the clamping bar 7 are then such that the lower supporting beam 21 rests on the rail heads of the rails arranged underneath, the upper supporting beam 21 rests on the rail heads of the rails laid on the lower supporting beam 21 and the clamping bar 7 with its bearing surface 8 rests on the rail heads of the laid on the upper support beam 21 rails. In this position, the screw sleeves 15 and 16 are tightened so that they form with the abutment surface forming stop collar 17 at corresponding bearing surfaces of the clamping bar 7, for the threaded sleeve 15 on an upper edge surface of the bearing sleeve 10, for the threaded sleeve 16 on an upper surface Holding claw 11 rest. Now, by pressing the hand pump 44, the hydraulic fluid is pressurized, so that the act via the hydraulic lines 45 with the hydraulic fluid hydraulic plunger 46 move the rail support surface 5 vertically upward from the body 6 of the base 4 out and in the direction of the clamping bar 7. The thus applied clamping force leads to an elastic deformation of the spring assemblies 28 and a deflection of the bearing surface 8, wherein the spring assemblies 28 apply a corresponding counterforce and thus exert a force acting in the opposite direction clamping force. In this way, the clamping force is exerted on the recorded in the rail support device 1 rails in two directions, namely once vertically from bottom to top (by means of the actuator upwardly displaced rail support surface 5) and once from top to bottom (by the force exerted by the spring packs 28 on the bearing surface 8 counterforce). By means of these special measures and design, it is achieved, on the one hand, that the application of the clamping force required for the formation of a secure hold of the rails in the rail support device 1 can be accomplished simply and without a special and complex tool, in particular without a crane or large tools. In addition, the applied clamping force is evenly distributed and very effective by the force in both directions in the vertical direction opposite directions.

In FIG. 8 it is shown that in any case the bearing surface 8 has an elastic support 35 which elastically deformed during application of the clamping force and so around the rail heads of those rails S sets and fixes against which it rests. In particular, in the enlarged view in FIG. 8 on the right, this is easy to recognize, it being also evident here that the two rails S which are drawn by way of example are of different heights, that is to say with different distances between the underside of the rail foot and the top of the rail head, the rail S shown on the right in FIG higher than the rail S shown on the left. Such an elastic support 35 can also be formed on the support beam 21, at least on its pressure surfaces 23. It is also possible to provide the rail support surface 5 and the support surfaces 22 with corresponding elastic supports 35.

The clamping mechanism of the rail support device 1 according to the invention may in particular be provided with a blocking means which blocks or locks the rail support surface 5 in a position once set after application of the clamping force by means of the hydraulics and the hand pump 44. Such a blocking means can contribute in particular to the fact that the actuator does not have to remain permanently activated while the rails are held in the rail support device 1 and held clamped. Thus, for example, the hydraulic system can be relaxed after setting the blocking agent.

Such a blocking means, as shown in the embodiment, as follows and in the FIGS. 9 to 11 be realized shown:

• In the body 6 of the basic threshold 4, a locking slide 37 is arranged displaceably in the horizontal direction. This has stepped sections 38, here three such stepped sections 38 in the direction of its longitudinal extension (corresponding to the longitudinal extension of the base threshold 4) arranged one behind the other such sections 38. In the stepped sections 38 stepwise and stepped successively arranged horizontal contact surfaces are formed, each to a same vertical jump spaced from each other and in the direction of the longitudinal extent of the locking slide 37 are each formed the same width.

At the rail support surface 5 forming, relative to the body 6 in the vertical direction movable element downwardly projecting and corresponding to the stepped portions 38 of the locking slide 37 stepped sections 39 are formed, which have equally stepped contact surfaces with the same height gradations and width dimensions.

The bolt slide is connected via a compression spring 40 which is placed on a shaft 41 formed on the bolt slide 37 and is supported on an abutment, in a in the FIGS. 10 to 11 biased to the left-facing direction, a direction in which the stepped portions 38 fall in a wedge shape.

Now, if the rail support surface 5 issued by pressing the hand pump 44 and issue the hydraulic ram 46, or raised against the force of the spring pacts 28 in the clamping bar 7, so the compression spring 40 presses the bolt slide 37 in the in the FIGS. 9 to 11 left lying direction, so that the stepped portions 38 of the bolt slide wedge-like to the stepped portions 39, which are connected to the rail support surface 5. Due to the interaction of the so to come to lie opposite bearing surfaces of the two cooperating stepped sections 38 and 39, a stop is formed, which - by the force exerted by the spring assemblies 28 in the clamping bar 7 clamping force, a force and Positive locking results and even when switching off the hydraulic pressure and thus inactivate the hydraulic ram 46 holds the relative position of the rail support surface 5 to the body 6 of the base threshold 4. The hydraulic pressure can be achieved via a here not closer to the lever on the hand pump 44.

To release this lock hydraulic pressure is again built up with the hand pump 44, the hydraulic pressure rams 46 are extended again until the wedging of the stepped sections 38 and 39 solved. About a pivot lever 42 can then the bolt slide against the spring force of the compression spring 40 back in the in the FIGS. 9 to 11 lying right lying back to a starting position, in which the stepped sections 38 and 39 allow a return of the rail support surface 5 in the lowest starting position. Then, the hydraulic pressure is released and the rail support surface 5 deviates downward due to the weight load, returns to its original position. The clamping bar 5 can then be lifted and the rail support device 1 are unloaded.

The rail support device 1 shown and described in the embodiment shown is typically installed on a rail transport car, to which it is provided with mounting plates 36, which can be bolted to a load-bearing surface of the rail transport vehicle, for example planked with wooden sleepers. The rail support device 1 according to the invention is usually arranged with two such devices in a row in a central portion of a rail transport vehicle, the rail transport car is otherwise equipped with conventional and especially not equipped with clamping bar 7 rail support devices. This ensures that the transported rails are fixed only at a few points, sufficient freedom of movement is maintained in the intermediate sections, for example, to be able to negotiate deformations occurring during turns or ascents, without risking damage to the rails and / or while the smooth ride of the rail transport train is at risk, for example derailment is risked, namely, if the rail transport cars of the rail transport train curve radii not understand or bends in the course of gradients can not go because of a stiffening effect of no longer sufficiently flexible, loaded on the car rails.
