Description

Flexible rail support with open or closed rail superstructure for rail vehicles

BACKGROUND OF THE INVENTION The present invention relates to a flexible support for rails with an open or closed rail superstructure for rail vehicles, in which rails are held on both sides by rigidly fitted elastomeric or similar profiles with support profiles, for example angled sheets vertically movable above a floor support body of e.g. grates or sleepers, the supporting profiles being fixed to the floor support body by means of anchor bolts.

Current_technologies

In the known flexible bearing for broad-rails, also called Vignol rails, the support profiles in the form of angular plates are fastened directly by means of anchor bolts to the floor support body, and an open upper, for example a ballast bed, is provided. Such a bearing of the rails has the disadvantage that in the event of wear on the rails or in the event of a necessary pitch correction, it is only possible to apply welding or replacement of the rails. This metoia is costly and leads only to the desired success. By means of such deposition welding, the shape of the rail is unsuitable.

Flexible grooves are also known for grooved rails, which are also suitable for closed superstructure. In such a known solution, described in EP 0 180 118, the trough rails are supported on a flexible potting compound which itself is provided on a support body of concrete slabs. Elastomeric profiles are fixed on both sides of the grooved rails, which are essentially closed at the top with the rails and to which, for example, paving stones> or bitumen are attached laterally from the upper. only by welding. In addition, noise damping is insufficient here and cracks or slits are disadvantageously formed between the flexible rail mounting profiles and the side-closed upper. In addition, it is disadvantageous that the replacement of rails with this flexible rail support is very costly.

Substance_of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned drawbacks and to provide a flexible rail support suitable for both wide rails and so-called Vignol rails or grooved rails which allows easy rail mounting and dismantling. without the need for spot welding. In addition, this flexible rail arrangement has high damping values in terms of sound absorption.

The problem is solved by the flexible mounting of the rails according to the invention, which is based on the fact that on the one hand the supporting profiles, in particular the angle plates, are supported by horizontal sections on the support body and fastened thereon by clamping tabs; the eccentric insert, which has means for rotatable driving, is rotatably mounted, on the one hand the anchor bolts are arranged upwardly in the holes of the support bodies and the eccentric inserts, and on the other hand the eccentric inserts, clamping plates and support bodies are locked or

The assembly and disassembly of the rails thus becomes very simple and economical. Indeed, when the rails need to be replaced, in the case of an open upper, the nuts on the anchor bolts need only be loosened and the clamping plates swiveled laterally, which makes it possible to pick up the rails to be replaced, including the elastomeric profiles and support profiles, Thereafter, the elastomeric profiles and support profiles are released from the rail and connected to a new rail, whereupon the support profiles are then restored to the support bodies. Subsequently, the clamping plates are turned back into their clamping position and the nuts on the anchor bolts are tightened firmly. It is then possible to provide, for example, a ballast bed. If the rails have not yet worn considerably, the rail guide can be repaired by avoiding the welding process by loosening the nuts on the anchor bolts and turning the eccentric inserts so that the rails compensate for the traveled sections laterally. These measures can be implemented in a very economical way in terms of time and cost in comparison with the methods implemented hitherto. The flexible rail support according to the invention is optionally applicable to both grooved rails and wide-rail rails, so-called Vignol rails. In both cases, it is possible to insert the elastomeric profiles with which the supporting profiles, for example angular sheets, engage externally in the cavities on both sides of the rails. In any case, high damping of sound transmission in the solid material is also achieved because the flexible free suspension of the rails avoids sound transmission in the solid material when traveling on the rails. All these advantages are achieved with easy rail accessibility and rail fastening.

Advantageous embodiments of the elastic bearing according to the invention follow from the further claims. Thus, for example, it is possible to utilize the elastic bearing of the rails according to the invention even when the upper is closed, provided that covering bodies for supporting bodies, clamping plates, eccentric inserts and anchor bolts are arranged on both sides and parallel to or adjacent to each rail. they are supported on clamps and on the floor support body. These cover bodies allow the rails to be replaced without difficulty, even when the upper is closed, since there is no need to disturb the overlap of the track made of paving stones, concrete slabs or bitumen, but only the cover body can be removed. All conventional covers, such as cobblestones, concrete slabs or bituminous material, may be attached externally to the cover body. Repairs to the rail cover are considerably reduced, since there is substantial separation between the rails and the rail cover.

According to a further advantageous embodiment of the invention, the supporting profiles, in particular the angle plates of the cover body, are firmly held in their mounted position. If the support profiles are formed, for example, of angle sheets, the rail side cover bodies can be provided with flat horizontal grooves, which, when assembling the cover bodies, engage the edges of the inclined upward angled plate sections.

According to a further advantageous embodiment of the invention, the grooves between the outer side of the wide rails and between the cover bodies or the grooves between the outer sides and the inner sides of the groove rails and between the cover bodies are filled with filler tapes, for example of plastic. These filling tapes can also be easily removed when the rails are removed and reused after the rails have been installed.

The cover bodies may consist of plastic, rubber, concrete or metal. For economic reasons, plastic coverings are preferred.

According to a further preferred embodiment of the invention, the eccentric inserts extend over the clamping plates by an annular collar. Furthermore, they can be provided, for example, with axial parallel holes for rotational drive. When tightening the nuts on the anchor bolt, the annular collar is pressed against the clamping tab, which, like the clamping foot, clamps against the horizontal section of the support profile. With loose nuts on the anchor bolts, the eccentric inserts can be rotated by means of a corresponding tool to engage the holes provided in the eccentric inserts parallel to their axes for the aforementioned repair of the rail guide.

According to yet another advantageous embodiment of the invention, the support bodies can consist of inverted U-shaped rail pieces, square tube pieces or plastic bodies which are arranged transversely to the longitudinal axis of the rail on the floor of the support body.

The invention is explained in more detail below with reference to the drawing.

FIG. 1 is a schematic cross-sectional view of a flexible rail support according to the invention which is formed as an open superstructure.

FIG. 2 is a schematic cross-sectional view of the flexible rail support of FIG. 1 for a pair of rails, but with a closed rail superstructure;

The flexible mounting of the wide-rail rails 10, also called Vignol rails, shown in FIG. 1 is suitable for an open or closed rail superstructure. For example, a concrete slab support body 11 is provided as a base. However, concrete grates or sleepers made of concrete, wood, plastic or steel can also be provided as floor support body 11. It is envisaged that the wide-leg rails 10 will first be mounted in two rows on the support bodies 11 during assembly and that they will be mounted in a suitable manner, as will be described hereinafter in connection with FIG. 1. After the mounting of the wide-rail rails 10, the rail joints are first welded before the rails 10 are aligned and positioned in the determined lateral and height positions in the usual manner. In this case, the distance A is set between the underside of the wide rails 10 and between the upper side of the support bodies 11, which is to be, for example, approximately 10 mm. Then, the boreholes 12 are formed for the anchor bolts 13 and the anchor bolts 13 are fastened in the bores 12 in the usual manner. The anchor bolts 13 pass through holes 14 formed in the support bodies 15. The support bodies 15 are mounted on support bodies 11 formed of concrete slabs and, in the present embodiment, consist of inverted U-shaped rail pieces. it was possible to use pieces of square tube or plastic body. It should be pointed out that these support bodies 15 are supported at their mutually opposite ends at a distance from the wide-angle rails 10. The anchor bolts 13 and hence the support bodies 15 are arranged in two parallel arranged rows at intervals of approximately 60 cm in the linear course of the rail 10 or approximately 30 cm in the arcuate region of the rails 10. w, · of these rows below the tongues 15, the support profiles, for example, the angle plates 16, by means of their horizontal sections 17 of the broad rail 10, are supported by means of elastomeric profiles 18 fixed on both sides by the shaped plates 16 at a distance A, i.e. with vertical clearance. The elastomeric profiles 18 and the angle plates 16 are continuously arranged in the axial direction of the wide-rail rails. The lengths of these components shall be of such dimensions that they can be transported, mounted or demonstrated in the usual way,

The angle plates 16 are fastened to the support bodies 15 by means of clamping plates 19. The clamping plates 19 have, as shown in FIG. 1, an angular cross-section, with an opening 21 always formed in the vertical arm 20 of the clamping plates 19. an eccentric insert 22 is rotatably inserted in the clamping plates 19, which over the upper side of each clamping plate 19 overlaps or abuts the annular collar 23, respectively. Nuts 24 are screwed onto the threaded section of the anchor bolts 13, and an elastic washer 25 is provided on the anchor bolt 13 between each nut 24 and between the annular collar 23 of the eccentric liner 22. When the nuts 24 are tightened, the clamping washers 19 with its horizontal arms 26 on the horizontal sections 17 of the angle plates 16, which are thus fastened to the supporting bodies 15.

If, over time, the Vignol rails 10 have run-in sections and if their track needs to be adjusted, it is only necessary to release the magics 24 on the anchor bolts 13 and to rotate the eccentric inserts 22 accordingly to realize lateral adjustment of the Vignol rails. In order to rotate the eccentric inserts 22, it is possible, for example, to provide holes (not shown), which are parallel to the axis, which in turn enable pivotal driving of the eccentric inserts. Punching tools. Alternatively, the handle ring may be formed with multiple edges, thereby allowing the corresponding screwdriver or screwdriver to be fitted with the corresponding key collar. For draining the rails, rail draining boxes (not shown) can be mounted in a known manner and which can be connected to treated drainage pipes. In the embodiment with an open rail superstructure, gravel can be placed between the two strips of the Vignol rails 10 and laterally from the two rails 10. However, if a closed track superstructure is needed, the system shown in FIG. 2 can be followed. The flexible rail support shown in FIG. 2 corresponds to that of FIG. 1, therefore identical parts are identified by the same reference numerals.

For the production of a closed track superstructure, cover bodies 27 are provided on both sides and parallel to or adjacent to each Vignol rail 10, which have a slight distance therefrom, which, with the vertical arm 28, rest on the supporting bodies 11 of concrete slabs and which The anchor bolts 13, with their nuts 24 screwed in, are in this case provided in the cavity 30 in the cover bodies 27, which is designed to be continuous. The cover bodies 27 extend over the support bodies 15, the clamping plates 19 with eccentric inserts 22 and the anchor bolts 13. The height of the cover bodies 27 is in such a way that their upper side of the wall is laterally aligned with the upper side of the Vignol rails. having a length such as to extend over, for example, three or four support bodies 15, clamping plates 19 and anchor bolts 13. wherein the cover bodies 27 are mutually opposed to each other in the side walls of the cover bodies 27 facing the Vignol rails 10, there are 10 longitudinal grooves 31 in which the edges are oblique *

The angled plates 16 and / or the supporting profiles thus firmly hold the cover bodies 27 in their mounted position. The grooves between the outer side of each Vignol rail 10 and the outer cover body 27 above the elastomeric profiles 18 are filled with filler strips 32, for example of plastic. Through the drainage channels 33 provided in the cover bodies 27, water that has accumulated in the free grooves between the Vignol rails 10 and the cover bodies 27 can drain off. The space between the inner, opposite cover bodies 27 can be filled with any rail cover 34 which it may also include an installation pipe 35. This may be paving, bitumen, concrete slabs, grass, etc. This rail cover 34 has a construction height which corresponds to the cover bodies 27 and the Vignol rails 10, with a rail cover opposite the inner cover bodies 27. 34 is provided, for example, with plastic plates 36. The cover bodies 27 may also consist of plastic, but also of rubber, concrete or metal.

The capping bodies 27 which are provided on the outer side vignole rails 10 can be subsequently join © ^»1 any track cover ,, e.g., pavement, bitumen, concrete slabs, grass and the like.

The drainage of the open grooves beside the broad-rails 10 above the elastomeric profiles 18 takes place, as previously mentioned, via the drainage channels 33 into the cover bodies 27 and further by means of rail drainage boxes (not shown) and drainage ducts into the treated channel.

In order to repair the track or to replace the wide rails 10, no breakage of the rail covers 34 is necessary, but it is sufficient to remove only the cover bodies 27 and the filling strips 32. These components can be reused after the rails 10 have been replaced.

The above-described flexible rail support 10 is also suitable for the so-called grooved rails, both with open and closed track superstructure. In the case of a closed track superstructure, possibly grooves between the outer sides of the groove rails 10 and between the cover bodies 27 can be filled with filler tapes, for example of plastic.

In the previously described flexible rail support, it is suitable for rail vehicles of any type, including trams. In the latter case, it is advantageous that no extraneous, in-ground installations or in-house installations are endangered by stray currents.
