Description

RAIL SUPPORT DEVICE

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

Rail support devices of this type are used to transport railway tracks on rail transportation waggons which have been assembled into rail transportation trains, in this respect, especially long-welded rails which have already been prepared or prefabricated from short rails in a rail welding plant (these being rail sections of up to several hundred metres in length) are transported to track construction sites, for example, in order to there belaid in the track and connected to the rail infrastructure.

In this respect, the long -welded rails are typically lined up in a plurality of layers on girders which are arranged vertically one above another and extend transversely to a longitudinal direction of the rail transportation waggons. Rail support devices of this type are known, for example, from DE 43 12 964 Al, DE 44 18 376 Al and from DE 20 2004 019 243 Ul. However, m these rail support devices known from these documents, the rails In the uppermost layer ere arranged with their rail heads exposed in a vertical direction and are not further secured. Although the rails are secured there against sliding sideways by laterally arranged securing elements, It has been found thaf especially In the esse of particularly lengthy long-welded rails arid in the case of great transportation distances, the long-welded rails shift lengthways which, in the worst case, can result in collisions with structures on the rail transportation waggon arid can thereby result, in damage which can entail repair costs and malfunctions.

Accordingly, a solution to this problem has been devised, whereby in this solution basically a horizontally extending clamping bar is positioned on the uppermost layer of the rails, arranged on the rail support devices, and a pressing force Is applied by a tensioning mechanism to this clamping bar in the direction of the rails heads. Thus, rail transportation waggons which have been devised and operated by Voestalpine AG, Austria, are known and are in use, which have rail support devices, in which supporting beams for supporting rails can be inserted Into two U-shaped profiled, vertically extending supports directed towards one another with the openings of the U-profiles, and which can be provided with a damping bar which can be positioned on the uppermost layer of the rails which have been received and can be screwed together by damping screws which pass through, on threaded rods, the openings in the outer ends of the damping bars and can be pressed against the uppermost layer of rails, in this concept, rail transportation supports of this type which are provided with clamping bars are arranged distributed on the rail transportation waggons oniy In relatively large intervals, located in front and behind are rail transportation supports without such clamping bars and without a clamping of the deposited rails to thus allow the rails to move out during cornering manoeuvres and to prevent damage to the transported rails due to high .bending moments, in the intermediate region to short clamping intervals.

Although this previously known system can clamp the rails placed; on the rail support device and can thereby prevent the ralis from shifting lengthways, this construction nevertheless suffers from disadvantages and has room for improvement, in particular, the handling of the clamping bar which always has to be lifted out of the U-shaped guides of the vertical supports for loading and unloading the rails is difficult, it necessitates the use of a crane due to the weight of this clamping bar, which crane accordingly has to be kept, available or has to be provided not only at the loading site, but particularly also at the unloading site which is often a construction site located outside the region of relatively large installations, f-'urthermore, the fixing and clamping of the clamping bar by the holts is laborious and again requires the use of a specific tool, namely an appropriately configured combination spanner for tightening or loosening the nuts. Moreover, here the applied clamping forces cannot he set in a satisfactorily reproducible manner, which Is also considered to be a disadvantage.

The clamping bar In the known solution described above has on its side facing for resting on the rail heads of the uppermost layer of the rails received in the rali support device a wooden board by which it rests on the rails heads, in this respect, it can be observed that different pressing forces are exerted on the rails received next to one another in the uppermost layer of the rails in the rail support device, on the one hand dus to different dimensions of the rails ensuing on: account of manufacturing tolerances (particularly in the height, of the rail, pleasured level with the rail foot to level with the rail head) and on the other hand due to an imprecise shaping of the wooden board. Here, it can even happen that in spite of tbs clamping bar being braced against the uppermost layer of rails, individual rails experience only a low contact pressure or even no appreciable contact pressure at ail,, and thus they are not securely fixed, as desired, by the clamping bar. Therefore, this also needs to be Improved, A further rail support device with supports (102,104). a ground sill (2a), a clamping bar {26}r a clamping mechanism (4), a bearing surface (58) of the clamping bar (26) which can he moved vertically relative to a body of the clamping bar (26), and can be actively advanced in the direction of the rail supporting surface by an actuating drive (70) is known from jp 2000 108 896 A.

Accordingly, the object of the present invention Is to provide a rail support device of the type mentioned at the outset which has a clamping bar in combination with a tensioning mechanism for applying a clamping force to the uppermost layer of rails in the rail support device and which is easier to handle and has an improved reliability in respect of the clamping effect.

This object is achieved according to the invention by a rail support device having the features of claim 1. Advantageous developments of a mil support, device of this type according, to the invention are set out and described in detail in the dependent claims 2 tO 14,:

According to the invention, the nevet rail support device thus has, and this Is initially consistent with the prior art; two opposed vertical posts, laterally delimiting a support region, a ground sill extending In a vertically lower region between the posts, defining on an upper side a rail support surface for depositing rads, a horizontally extending clamping bar which is arranged above the ground sill, which can be fixed to the posts and which has a hearing surface on an underside for resting on rail heads of a layer of rails: placed on the rail support device, and a tensiohing mechanism for applying a clamping force which is vertically effective between the ground sill and the clamping bar.

The novel tail support device differs front the known prior art in that the rail support surface can be moved verticaiiyreiativetp a body of the ground sill, and in that the bearing surface can be moved vertically relative to a body of the clamping bar, and one of the mentioned surfaces. Le. the rail support surface or the bearing surface can be actively advanced by means of a drive in the direction of the respective other surface, i.e. the bearing surface or the rail support surface, and the respective other surface. Le. the bearing surface or the mil support surface is prestressed by an elastic resetting means in the direction of the one surface which can be actively advanced in the direction of the other surface by means of the drive, i.e. the rail support surface or the bearing surface.

Various advantages are realised by this innovation and constructive reconfiguration according to the invention compared to the known prior art:

Thus, an appropriate drive can be configured in particular such that it can be actuated without an accompanying tool, f urthermore, due to the combination of an active advance of one of the surfaces, bearing surface or raii support surface, and the passive release of a counter force by the elastic resetting means which prestresses the other surface, bearing surface or rail support surface, in a clamping direction, a uniform and more effective Introduction of the clamping force Is achieved. In this respect, the drive can advantageously also be configured such that ft allows a reproducible application of a selectable clamping force, It can be provided, for example, with a device indicating and/or observing a variable representing the clamping force, for example in respect of the current consumption of an actuating drive, driven by an electric motor, or by the pressure of a hydraulically or pneumatically operated actuating drive.

In this respect, the drive Is advantageously a hydraulically operated drive. The advantage of a hydraulicaiiy operated drive is that it can generate and transmit high forces. Likewise, as provided according to a further advantageous development of the invention, it can be configured as a manuallyoperated drive if this has a bydrauiie mandai pump, for example. This form of the drive allows a configuration with no requirement of an energy' supply fed from outside, for example a power supply, so that, the raii support device according to the Invention can ultimately be configured and formed as a self-sufficient unit.

The elastic resetting means can advantageously comprise spring packages which ere arranged between the surface provided with the elastic resetting means, i.e. the bearing surface or the rail support surface, and a housing in which this surface can be moved in a vertical direction. Spring packages of this type can be realised constructively In a relatively simple manner, for example they can he formed as laminated disc springs. Due to the configuration with a plurality of spring packages of this type which can be arranged In tandem in different positions particularly in the element in which they are fitted (ground sül or clamping bar) in the respective longitudinal direction of said element, i.e, in the direction in which the vertical posts are opposite one another, it is also possible to achieve a very specific distribution of the damping force. Due to an individual configuration and choice of the spring force of the individual spring packages, it is even possible to influence a clamping force profile, to thereby be able to make appropriate adjustments of the required damping force to the position which is required in respect of the horizontal and lateral positioning of the rails.

According to a further advantageous development of the invention, it is possible to provide in the mil support device according to the invention in a vertical direction between the ground sül and the clamping bar at least one girder which can be fixed on the posts such that it Is vertically displaceable, extends in a horizontal direction and has on an underside a pressing surface for resting on rai! heads of rails arranged under the girder and has on an upper side a bearing surface for rails which have been deposited and are supported on tbs girder, A girder of this type allows rads to be received In the rail support device in a further vertical stacking plane, so that a correspondingly greater number of rails can be deposited on the rail support device, in this respect, it is important that the girder can be fixed on the posts such that It can be moved in a vertical direction, it Is thus possible, If a damping force can be applied between the clamping bar and the ground sill by means of the tensioning mechanism comprising the vertically displaceable surfaces of rail support surface and bearing surface as well as the actuating drive, for the clamping force to be applied to the superimposed planes of the deposited rails and to be accordingly transferred vertically onto and above the girder. In this respect, mors than one such girder can also be provided in particuiar, for example two such girders can be provided so that further superimposed layers of rails can he stacked for transportation, thus in the case of two girders accordingly three layers of rails, it is stressed that In the case of a plurality of such girders, it is crucial that aii the girders are fixed on the posts in a vertically dispiaceabie manner, so that the applied clamping force can act on all the

Sayers of the verticai superimposed rails. The girders respectively damp with the pressing surface the lewer layer of rails by applying the damping force or by transferring the damping force onto the rail heads of this layer, and cfamp with the bearing surface the upper layer of rails from the rail foot side.

The one or the piuraiity of girders can advantageously he fixed to one of the posts such that it/they can pivot about the vertical axis thereof. This type of construction means that the girders, which can aiso be called "rotary sills" in this embodiment., do not have to be lifted off completely from the vertically extending posts in order to load rails onto or to unload them from the rail support device, instead, the. girders can simply be pivoted about the vertical axis of the post on which they are pivotally fixed, and they can thus be brought out of the overlap with the rails or with the surface provided for supporting the rails,, so that the rail support device can be loaded and unloaded, in this respect, it Is possible to provide on the post on which the girder is fixed such that It can pivot about tire vertical axis thereof and is vertically displaceable on the post, girder lifting means which, during a pivoting movement of the girder about the longitudinal axis of the post on which St is pivotaiiy fixed, cause the girder to perform a vertical movement. This produces at the same time, during the pivoting of the girder, a raising movement from the layer of rails on which the girder rests with its pressing surface, so that this raising movement is not accomplished by lifting the girder manually, but takes place at the same time as the pivoting movement. Here, a link guide for example (or a pivot bearing with a link guide of this type) can be formed, as described and disclosed in DE 202004015248 U.I. furthermore, if the rail support device according to the invention provides at least one girder, the pressing surface and/or the beering surface of this girder can be provided with an elastic cover. An elastic cover sf this type can be, for exemple, a herd rubber mat which is applied to the appropriate surface or is introduced into said surface. An elastic cover of this type can advantagedusiy produce a further and Improved fixing ei the rails placed on the respective surface, in that due to the elastic deformation of the cover, the pressing surface ortho bearing surface is deformed on account of the clamping force applied by the actuating drive and possible differences in height, arising due to tolerances in the rail dimensions, are compensated thereby, thus ensuring that all the rails experience a corresponding clamping effect.

According to a development or the invention, the damping bar can advantageously he fixed to one of the posts such that it can pivot about the longitudinal axis thereof. In a similar manner to the above description concerning the girders which are to be optionally provided, In the context of the clamping bar a solution of this type also provides the advantage that the clamping bar does not have to be completely lifted off the vertical posts. Instead, It is sufficient to pivot the damping bar, expending oniy 5 relatively smail amount of force, thus exposing underlying rails or a surface for supporting the rails, in this respect, it can advantageously be provided that the clamping bar is fixed to the post not oniy pivotally about the vertical axis thereof, but furthermore also dlsplaceably in a vertical direction. Thus, the clamping bar can he adjusted In height accordingly to provide the pressing force or clamping force. At the same time, during the pivoting movement, the clamping bar can also be raised from the layer of rails on which it rests, in a similar manner to t he above description in respect of the optional girders, this lifting movement can be supported by clamping bar lifting means which, during a pivoting movement of the clamping bar about the vertical axis of the post on which the damping bar is pivotally fixed, cause the clamping bar to perform a vertical movement. Here as weil, It is possible to advantageously select a link guide, as described and disclosed In DE 20 2804 OfS 248 Ü1.

Further advantages are provided by a deveíopmeotof the rail support device in which the raii support surface of the ground sill and/or the bearing surface of the clamping bsr is/are provided with an elastic cover. An elastic cover of this type can be applied to the bearing surface or to the rail support surface or it can oe introduced into the relevant surface. Here again, it can be in the form of a hard rubber mat, for example, in the manner described above for the analogous elastic cover which is possible as 3 configuration option for the girders to be optionally provided, an elastic cover of thio type affords the advantage of a clamping effect, ensured for ail: the rails, by compensating height differences within layers of rads, which height differences arise due to manufacturing tolerances, for example, A further development provides that the rali support device of the invention can have a mechanics i locking means which causes the releasable locking of the surface advanced by the actuating drive (he. the rail support surface or the hearing surface) in a vertical position adjusted by the actuating drive. When the required or desired clamping force is applied by means of the actuating drive, a mechanical locking means of this type can advantageously lock or fix in position the surface which is actively moved by the actuating drive,, so that the actuating drive can be disconnected and does not have to be kept continually activated to apply or maintain the core force during a period of use, for example during a transportation journey for transporting rails, if the clamping effect is then to be stopped to release rails which are arranged on the rah support device and are clamped therein, the locking means is released end is brought. Into a release position from a locking position. In order to release the locking means, for example the actuating drive can be activated to relieve the locking means by applying a clamping force and to allow the locking means to move Into the release position. By a locking means of this type, the actuating drive is thus equally provided with a seif-locking effect which maintains the once assumed position of the element positioned by the actuating drive, even if the actuating drive Is connected without power.

In a further advantageous constructive development in which the clamping bar is arranged in a vertically displaceable manner on the vertical posts, the rail support device according to the invention can have on the vertical posts counter- bearing elements which are arranged above the clamping bar and are vertically adjustable In the longitudinal direction of the posts. This type of embodiment allows sh adjustment of the vertical height position of the clamping bar so that it can he adapted to the stacking height of the rails received in the rail support device. Counter-bearing elements of this type can be formed, for example, by threaded bushes which are advantageously secured by counter nuts arid which form on their surface facing the clamping bar a corresponding counter-bearing surface, in this respect, cylindrical holding portions, for example, can be formed which project above the cou nter-bes ring surfaces in the direction of tbs clamping bar and which have a greater diameter then a stop portion of the posts, so that the clamping bar can be placed over the post with an open annular receiving region which has a olrcumferentiai enclosure including more than 18CP and sn opening width which is greater than the diameter of the contact portion of the posts In the contact portion and then by vertically advancing a counter-bearing element of this type such that the cylindrical holding portion passes inside the annular receiving region, it can be locked in a form-fitting manner, in the rail support device according to the invention, the raiI support surface in the ground sill can advantageously be the surface which can he actively advanced in the direction of the bearing surface by means of the drive, whereas the bearing surface in the damping bar is prestressed in the direction of the rail support surface by the elastic resetting means. A soiutlon of this type has proved to be advantageous since the clamping bar must always be moved and displaced for loading and unloading the mii support device, whereas the ground sill is arranged to be stationary all the tinte. The actuating drive can be integrated Into a stationary element more easily and with less constructive effort,

The· figures show and represent an embodiment of a rail support device, configured according to tbs invention, in different views, in the following, this embodiment, will be described with reference to the figures. In this respect. It Is stressed that the figures are not complete constructional drawings, but are suhstantlaily schematic drawings of the elements which are essential to the Inventicm, and of further advantageous configurations and features, in the figures, a rail support device according to the Invention is denoted very generally by reference numeral 1. it contains as essential elements two mutually opposite posts 2 and 3 which are arranged at a distance from one another and extend vertically by their longitudinal direction, as weil as a horizontally extending ground sill 4 which bridges the distance between the posts .2,. 3 in a lower portion of the rail support device 1, Formed in the ground sill 4 is s rali support surface 5 which is vertically displaceable relative to a body 6 of the ground sill 4.

Vertically above the ground sill 6 it is possible to see a clamping bar ? which is shown in Figs. 1, ?.. 8 and 13 in a position which Is fixed on the two posts 2, 3 and bridges the distance between the posts 2 and 3. On an underside facing the ground siil 6, this clamping bar 7 has a bearing surface 8 which, during operation of the rail support device 1 with rails arranged thereon, rests on rail heads of an uppermost layer of rails. This bearing surface 8 is vertically displaceable with respect to a body 9 of the clamping bar 7.

The clamping bar 7 Itself is fixed pivots ily and in a vertically displaceable manner on the vertical post 2, having a bearing sleeve It) which encompasses the post 2, which is circular in cross section, and Is formed iniegraiiy with the clamping bar 7, The clamping bar 7 engages around the vertical post 3 with a holding claw 11, formed to be partly annular in cross section, in the position shown in Figs. 1, 2, 8 and 13, In this respect, the clamping bar 7 can be pivoted about the post 2 out of the position shown in Figs. 1, 2, 8 and 13 to expose the underlying region, As the clamping bar ? pivots, the holding claw 11 is then released from the post 3, the bearing sleeve 10 naturally remains connected to tbs post 2, During a pivoting movement of this type which, in the view of Fig. 1, takes place In a movement directed forwards to the right, a link track 12, formed on an underside of the bearing sleeve 1Ö runs over a roller pin 13 fixed to the post 2., s vertical lifting movement being Initiated at the same time by the pivoting movement due to the cooperation of roller pin 13 and link track 12. in order te Iáé able to easily pivot the clamping bar 7, a handle 14 is formed thereon. Fig, 14 shows the position in which the damping bar ? has been swivelled Into the open position, In thia positlon;the clamping bet 7 has been placed down on a support 48 formed integrally with a stacking post 47, so that the bearing sleeve 10 does not have to permanently bear the weight of the holding bar 7 at. the end of a one-armed lever.

Verticaily displaceable counter-bearing elements in the form of threaded bushes 15 and 16 with annularly protruding step coilets 1? respectively for med thereon are arranged on the vertical posts 2 and 3 above the clamping bar 7. introduced into the stop coliét .17 over the circumference are openings IS which serve as a tool attachment to be able to attach a tool for screwing the threaded bushes IS and 16 Into place. As shown In particular by Fig. 5. the holding claw 33 Is provided with a partly annular recess 39, the circumferential extent, of which is above ISO”. Via an access opening 20, a support portion of the post 3, the diameter of which is selected such that it can be guided through the access opening 20 can be introduced into the recess 19, The threaded bush 16 has a cylindrical extension 43 which is reduced In diameter compared to the diameter of the stop collet 17, It projects downwards above the stop collet 37 (cf. Fig 12} and Is formed irr diameter corresponding to the diameter of the partly annular recess 19, so that this extension can be introduced from above Into the recess 39, Thus, by a corresponding displacement of the threaded bush 16 vertically downwards by the screwing thereof, this cylindrical extension 43 can be introduced into the recess 19 and it then positively locks the holding claw 11 due to the encompassing overlap above 280’ of the recess 19,

In this embodiment, two girders 23 are arranged in the vertical region between the ground sill 4 and the clamping bar 7. They respectively have a bearing surface 22. on the upper side thereof, onto which rails can be placed by their rail feet. On their underside, the girders 23 respectively have a pressing surface 23 by which they rest on rail heads of a layer of rails arranged below the respective girder 22. The girders 2.3. are arranged pivotally and vertically dispiaceably on the pest 2 similarly to the damping bar 7. The girders 2.1 also respectively have a bearing sleeve 24 surrounding the post 2 which is circular in cross section. On the post. 3, the girders 21 are fixed in a releasable manner by locking elements 25 In the position shown in Figs, 1, 2, 8 and 13. When the girders 21 are pivoted, a simultaneous vertical lifting movement Is also produced due to a link guide. The bearing sleeves 24 of the girders 21 also have for this purpose on their respective underside a link track 26 which cooperates with a correspondihg roller pin 27 which is fixed on post 2, The positions of the girders 21, pivoted into an open position, can be seen in Fig, 14. In this respect, the girders 21 have also been placed on supports 48 of the stacking post 47,

To securely damp rails received in the rail support device i, a tensioning mechanism applies a verticaiiy acting clamping force on the raiis, This tensioning mechanism comprises the verticaiiy displaceabie raii support surface 5, an actuating drive, to be described in more detail in the following, For the active vertical displacement of the rail support surface 5 in the direction of the clamping bar?, the bearing surface 8 and also an elastic resetting means which verticaiiy prestresses the hearing surface 8 in the direction of the ground sill 4.

As can be seen in particular in Tig. 4, in this embodiment, the elastic resetting means consists of a number of spring packages 28 which are arranged in tandem in the longitudinal direction of the clamping Par 7 and accordingly exert an elastic resetting force on the hearing surface 8. These spring packages 28 respectively have a plurality of disc springs 29 which are arranged in a superimposed manner and are combined into the spring packages 28. Fig. 7 is a more precise view of an enlarged detail of a spring package 28 of tins type. It Is formed by the superimposed disc springs 29 which are placed over a holt 30, arid by a guide bushing 55 which has been placed on the disc springs 29, acts as a stop arid is fixed and held in position by a crown nut. 52, screwed onto the bolt 50. The individual spring packages 28 can be adjusted with a varying spring force In the longitudinal direction of the clamping bar 7 to thus form a resetting force profile.

The rail support surface S is verticaiiy displaceable relative to the body 8 of the ground sill 4 by means of a hydraulic drive operated by a manual pump 44 (see Fig, 13), A hydraulic fluid reservoir and the manual pump 44 ars located in an equipment box 54 closabie by a door 5.5, The throughflow quantity of the hydraulic fluid can be regulated by a valve 49,

Actuation of the manual pump 44 pressurises the hydraulic fluid which is conveyed via hydrauifC: lines 45 to hydraulic rams 46 which are arranged in the iaody 6 and act on the rail support surface S,: The rail support surface § Is displaced vertically relative to the body 6 of the ground sill 4 by the hydraulic rams 46, namely It is moved upwards In the direction of the damping bar 7.

When the rail support device 5 has been fully equipped with tbe rails which are to be received.« i.e- whan rails have been received on the fali support surface 5 of the ground sill 4 and on the bearing surfaces 22 of the girders 21, the damping bar 7 is attached arid is placed on the rail heads of the uppermost layer of rails. The girders 21 and the clamping bar 7 are thee positioned such that the iowsr girder 21 rests on the rail heads of the underlying rails, the uppergtrder 21 rests on the rail heads of the rails pieced on the iower girder 21 and the clamping bar 7 rests with its bearing surface 8 on the rail heads of the rails placed on the upper girder 2.1. In this position, the threaded bushes 15,15 are then tightened so that they rest with the stop collets 17, forming the counter-bearing surface, on corresponding bearing surfaces ef the clamping bar 7, in the case of threaded bush 15 on an upper peripheral surface of the hearing sleeve '10. and in the case of threaded bush 16 on an upper surface of the holding ciaw 11. Then, the hydraulic fluid is pressurised by actuating the manual pump 44 so that the hydraulic rams 46, charged with hydraulic fluid via the hydraulic lines 45, move the rail support surface 5 vertically upwards out of the body 6 of the ground sill 4 and towards the clamping bar 7, The clamping force applied thereby results In an elastic deformation of the spring packages 28 and in a yielding of the bear ing surface 8, the spring packages 28 applying a corresponding counter force and thus exerting s clamping force which acts in the opposite direction, in this why, the clamping force on the rails, received in the rail support device 1, Is exerted In two directions, namely vertically upwards from below (by the rail support surface S displaced upwards by the actuating drive) and downwards from above (by the counter force exerted by the spring packages 28 on the bearing surface 8), These particular measures and this concept mean that It is possible to achieve the application of the damping force necessary for providing a secure retention of the rails in the rail support device .1 in a simple manner without a specific, complex tool, in particular without a crane or a large hand tool in addition, the applied clamping force is distributed uniformly and Is very effective due to the force effect in two opposite directions lb the vertical extent.

Fig. 8 shows that the bearing surface 8 has an elastic cover 35 in any case which, when the clamping force Is applied, is elastically deformed add Is thus placed a roti nd and fixes the rail heads of the rails S against which it rests. This can be seen pattlcuWly well Io the enlarged view on the right in Fig, 8, and here it can also be seen that the two rails 8, shown by way of example, are formed ht different heights, l.e. with different spacings between the underside of the rail foot and the upper side of the rail head, the rail S on the right of the figure being higher than the rail S on the left. An elastic cover 35 of this type can alsó be formed on the girder 23, si least on the pressing surface 23 thereof, it is likewise possible to also provide the rail support surface S arid the bearing surfaces 22 with corresponding elastic covers 35.

The tensioning mechanism of the rail support device 1 according to the invention can be provided in particular with a locking means which blocks or locks the rail support surface 5 in a position which is adjusted by· means of the hydraulic system and the manual pump 44 once the clamping force has been applied. A locking means of this type can help to ensure in particuiarthatthe actuating drive does not have to remain permanently active while the rails are stored and held in a damped manner In the rail support device 1. Thus, for example, after the locking means has been positioned, the hydrauiic system can be relaxed. A locking means of this type can fee realised as follows and as shown ip: Rgs, $ to 3.3.., as is also shown in the embodiment A bolt slide 37 is arranged in a horizontally displaceable manner in the body δ of the ground sill 4. The bolt slide has stepped portions 38, here three such stepped portions 38 arranged in tandem io the direction of its longitudinal extent (which corresponds to the longitudinal extent of the ground sill 4). Formed in the stepped portions 38 are horizontal bearing surfaces which are arranged in tandem in a step-tike and graduated manner and are respectively spaced apart from one another by the same vertical separation and are respectively formed 'with the same width in the direction of the longitudinal extent of the bolt slide 37.

Formed on the element which forms the rail support surface 5 and is vertically movable relative to the body S are downwardly projecting stepped portions 39 which correspond to the stepped portions 38 of the holt sildé 37 and which have in the same way stepped bearing surfaces with the same height graduations and width dimensions.

The boit slide is pretensioned in & direction oriented to the left in figs. 30 and 11, a direction in which the stepped portions 38 slope in a wedge-shaped manner, by a pressure spring 40 which is positioned on a shank 41 formed on the boit slide 37 and is supported on an abutment.

When the rail support surface 5 is moved out by the actuation of the manual pomp 44 and by the moving-out action of the hydraulic rams 46, and is raised against the force from the spring packages 28 in the clamping bar 7, the pressure spring 40 presses the boit slide 3? In the direction or! the left in Figs, 9 io 11, so that the stepped portions 38 of the bolt slide rest in a wedge-like manner against the stepped portions 39 which ere joined to the rail support surface 5. Due to the cooperation of the bearing surfaces, which thus come to rest opposite one another, of the two respectively cooperating stepped portions 38 and 39, a stop Is formed which, due to the clamping force exerted by the spring packages 28 in the clamping bar ?.. produces a force and form fit and holds the position of the rail support surface 5 relative to the body 6 of the ground sill 4 even when the hydraulic pressure is disconnected and thus when the hydraulic rams 46 have beers deactivated, the hydraulic pressure can be released via a lever {not visible) on the manual pump 44.

To release this locking effect, hydraulic pressure is built up again using the manual pump 44, the hydraulic rams 46 are moved out again until the wedge fastening of the stepped portions 38 and 39 Is released. Via a swivel lever 42, the bolt slide can then be drawn back again against the spring force of the pressure springxiö in the direction Oh the right in Figs, 9 to 11 Into a starting position in which the stepped portions 38 and 39 allow' the rail support surface 5 to be returned Into the lowest starting position. Thereafter, the hydraulic pressure is released and the rail support surface 5 yields downwards due to the applied weight force, and it «roves back in its starting position. The clamping bar 8 can then be raised and the rail support device .1 can be tmioaded:.

The described rail support device 1 presented in the embodiment which is shown is typically installed on a rail transportation waggon, for which purpose It is provided with fastening plates 38 which, for example, can be screwed down on a load receiving surface, olenkecfvyith wood sills, of the rail transportation waggon, in this respect, the rali support device 1 according to the invention Is usually arranged with two such devices In tandem In a central portion of a rail transportation waggon, the rail transportation waggon moreover being fitted with conventional rail support devices in particular not equipped with clamping bars ?, It. is thus ensured that the transported nails are only fixed at a few points, that an adequate freedom of movement is retained in the Intermediate portions in orderte he abie to respond to deformations which arise, for example, while travelling through a bend or up an incline, without running the risk of the rails being damaged or that the smooth travel of the rail transportation train is jeopardised, that for example there is a risk of derailing, namely if the rail transportation waggons of the rail transportation train cannot follow curve radii or if they cannot respond to bends in the course of Inclines duo to a stiffening effect of the rails which have been loaded on the waggons and are no longer sufficiently flexible,
