The support elements are arranged at mounting parts (20) that clampingly engage a rail foot. The mounting parts have two claw fasteners that are connected with each other by a tension spring. The support elements are arranged at an arm that laterally extends from the mounting parts, where the support elements are height adjustable.

Description

The present invention relates to a system for creating an escape, rescue or service route in track systems. It should be formed in a simple way, a tread in the track area.

Escape and rescue routes in the area of railway track systems are intended especially for use in tunnels. In the event of a fire or an accident, they should enable a safe evacuation of persons from the danger zone. Since the space available in a tunnel is usually limited in a tunnel, it is often necessary to lead people close to the track or even between the individual rails out of the tunnel. However, since locomotion in the conventional track bed is difficult and also associated with risks, provide such escape and Rettungswegsysteme a tread over which people can easily run out of the danger area, especially from the tunnel out.

Service routes, in turn, serve to provide personnel or general workers with the ability to conveniently travel within the track area. For example, a comfortable crossing of several tracks is to be made possible.

So far, it was known to implement such escape and rescue routes or service routes through wooden structures. These were mounted on the sleepers of the track and formed a tread extending substantially between the two tracks. The effort to install such systems, however, was relatively large, since the individual wood components had to be connected to each other individually and in several steps. Further, there is a general need to avoid such wood structures to remove the fire load from the tunnel. Since all components undergo a fire test, components made of wood should be completely dispensed with.

Another problem of this previously used solution is finally that the wood is exposed to external influences, which over time too Wear and tear and thus affect the functionality of the emergency route. Even though these external influences in the area of a tunnel are lower than in the open air, this does mean that the proper condition of these systems must be regularly monitored and repair measures often required.

The present invention is therefore based on the object of specifying a novel system for forming treads within the track area. The system should be as easy to install as possible to allow flexible installation of the escape or rescue route or service route.

The object is achieved by a system having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The erfmdungsgemäße system for creating an escape, rescue or service route is based on the use of special mounting parts having support elements for storing module elements, wherein a tread is formed by the module elements. The mounting parts are characterized by the fact that they clamp around the rail foot and accordingly a particularly simple assembly and disassembly is possible.

According to the invention, a system for creating an escape, rescue or service route in track systems is accordingly provided, which has a tread formed between the rails and / or laterally thereof, wherein the tread is formed by a plurality of module elements, which on several support elements are mounted, and wherein the support elements are arranged on mounting parts which engage around the rail foot by clamping.

The mounting parts preferably have two claws, which are connected to each other via a tension spring. In particular, the claws may be attached to two quivers which telescopically engage and engage one end of each of the tension springs. This design allows for easy and quick attachment of the mounting hardware to the tracks, which ultimately facilitates the overall creation of the escape, rescue or service route. Alternatively, the use of a screw connection would be conceivable.

Preferably, the support elements are each arranged on a boom, which extends laterally from the mounting part, in particular also on both sides the mounting part may be provided a corresponding support element. It can further be provided that the support elements are designed to be height adjustable in order to allow a horizontal alignment of the tread. This horizontal alignment can also be supported by the fact that the support elements are pivotally mounted or arranged on a pivotable holding part. Further, for example, it could be provided that the boom is integrally connected to one of the quivers in order to ensure a robust construction and easy installation. Finally, it would also be useful to arrange an insulating element in the region between the claws and the support element, which consists for example of POM (polyoxymethylene) or PE (polyethylene).

The module elements, which form the tread in their entirety, may for example be formed by gratings.

Fig. 1 shows as an application example of the system 1 according to the invention a Dienstweg 2, which should allow the easy crossing a track system consisting of two slightly oblique to each other or running towards each other running tracks 50, 51. The system 1 according to the invention becomes a tread 3 formed, which is formed between the rails or laterally thereof and extends substantially transversely to the tracks 50, 51.

The tread itself is formed by a plurality of module elements 10, which, for example, consist of gratings. The module elements 10 preferably have the same width, so that ultimately the width of the entire tread 3 is substantially constant. The length of the individual module elements 10 may, however, be different, depending on whether the module elements 10 are arranged between the rails of a track 50, 51, laterally thereof or between the tracks 50, 51. There is - as shown - of course, the possibility that the module elements 10 are designed trapezoidal or triangular. Finally, module elements of any shape can be used.

The peculiarity of the system 1 according to the invention consists in the support or storage of the module elements 10, which takes place via mounting parts 20 which are closer in the Fig. 2a and 2b are shown and will be explained in detail below.

The mounting parts 20 according to the invention are designed such that they allow a simple and fast attachment to the tracks 50, 51. For this purpose, a clamping mechanism is used, whose central components are claws 21 and 22, which are held by means of a tension spring 23 to tension, such that jamming with the rail is made possible. Strictly speaking, the claws 21 and 22 are respectively fixed to a quiver 24 and 25, wherein the two quivers 24 and 25 are designed such that they can telescopically engage with each other. The tension spring 23 is in this case connected to the two quivers 24, 25, wherein the connection with the front quiver 24 via a clamping screw 26 which passes through a front opening 27 of a arranged at the end of the quiver 24 U-profile 28 and here with a self-locking Nut 29 is screwed. With the help of a snap ring 30 unintentional loosening between the screw 26 and nut 29 is prevented.

When second quiver 25, the spring 23 is hooked by means of an eyelet 34 in a screw 32, which in turn is secured by means of a nut 33 to the quiver 25.

To mount the mounting part 20 on a rail foot, this is initially attached to the rail foot, that the claw 22 engages around the side region of the rail foot. The two intermeshing quivers 24 and 25 are here below arranged the rail foot. With the aid of a pulling tool which engages a bracket 34 arranged at the end region of the holder 24, the two holders 24 and 25 can then be pulled apart until the front claw 21 engages around the opposite side region of the rail foot. Due to the tension exerted by the tension spring 23 in this case a secure fit of the mounting member 20 is made possible on the rail.

From the quiver 25 further extends a lateral arm 40 in the form of a tube 41, on which the support element for supporting the module elements is arranged. The support element is in this case formed by a plate 45, which is arranged by means of a first nut 42 on a threaded pin 43, which in turn engages in a second nut 44. This nut 44 in turn forms the upper end portion of a vertical pipe section 46, wherein by means of the threaded pin 43 by a rotation of the plate 45, a height adjustment is made possible. As desired, accordingly, the height of the platen 45 can be adjusted within a certain range.

Like now Fig. 1 shows, to create the service path according to the invention several of the mounting parts 20 described attached to the rail feet and in this case form the support surface for the module elements 10. Outside the track area other support elements 15 can be used, which can be configured in any form. Preferably, in this case, the gratings are still connected to the mounting parts, for example. Via a screw to allow a fixed arrangement.

The advantage of the solution according to the invention is that the system allows a very simple and fast creation of a service route or an escape or rescue route. In particular, the attachment of the mounting hardware 20 to the tracks can be done in a very simple and fast way. The same applies to the disassembly of the system, since only a few steps are required to remove the mounting hardware from the tracks.

The Fig. 3a and 3b show a further variant of a mounting member 20 according to the invention, in which the same elements are provided with the same reference numerals. In this second variant of the boom 40 is designed to be longer than in the embodiment of Fig. 2a and 2b such that now two support plates 45 can be arranged side by side. This further expands the possibilities for arranging module elements.

Furthermore, the show Fig. 4a and 4b a further embodiment of a mounting member 20 according to the invention in this mechanically robust variant of the boom is integrally connected to one of the two quivers 25. Moreover, in this embodiment - mainly for reasons of stability - waived the height adjustment of the support plate 45. Furthermore, the claws 21, 22 are also designed to absorb extreme forces. The claw 22 connected to the quiver 25 of the boom is equipped with a, the quiver 25 integrally cross-section, for grasping the rail. Furthermore, the eyelet 34, which forms a point of attack for biasing the device, reinforced executed. It is formed by an axis which is inserted into two opposite bore openings of the claw 21 and welded there. Thus, the power of the eyelet 34 is no longer in the direction of the weld. These features, individually or in combination, lead to a mechanically extremely robust construction, which, however, is easy and flexible to handle.

The FIGS. 5a and 5b show a further variant of a mounting part 120 according to the invention, which will be described below.

A first peculiarity of this variant consists in the fact that the mounting member 120 is formed largely symmetrical, so provides support surfaces on both sides of the rail. For this purpose, two almost symmetrical arms 140 are provided, which in turn are formed as a quiver and telescopically mounted on a central piece 141. Accordingly, both arms 140 are displaceable relative to one another in the direction of the arrow in order to be able to be adapted to the dimensions of the rail foot. They have, as well as the previously discussed embodiments, claws 142 which engage around the rail foot. In contrast to the previously described tension mechanism with a spring, however, a screw connection is now provided, via which both arms 140 can be clamped to the rail foot. This connection will be later based on the FIGS. 6a to 6c described in more detail.

At the two ends of the arms 140 are then each vertically aligned foot portions 145 are arranged, which engage with their lower end portions in the form of hollow sections boom 140. By means of a screw, not shown, the foot portions 145 can be fixed accordingly to the arms. At its upper end, the foot portions 145 are hollow cylindrical - preferably with an internal thread - formed. Accordingly, they make it possible to engage in each case a threaded pin 146 (in the figures, this is shown only on one of the two arms), at the top of which Platen 147 is arranged. Again, the illustrated screw connection between foot section 145 and threaded pin 146 allows a height adjustment of the support surface. The foot portions 145 are preferably formed of an insulating material. For example, it would be conceivable to use POM or PE.

Another special feature of the illustrated embodiment is further that - as in FIG. 5b indicated - the foot sections used in the boom 145 before fixing a certain game and thus can be pivoted in a certain range relative to the arms 140 and tilted. The inclination of the foot portions 145 and thus of course the corresponding bearing surface of the support plate 147 can thus be easily changed. This is advantageous because the rails are usually arranged slightly inclined to the inside of a track to complicate a derailment of rail vehicles. The inevitably resulting inclination of the rail foot can then be compensated by a corresponding adjustment of the foot sections 145, so that ultimately a desired horizontal bearing surface is created. It should be noted that this particular type of pivotal mounting of the foot sections and / or the use of an insulating material could of course also be used in the previously described variants for the mounting hardware. Also it would be conceivable, the variants of FIGS. 2 to 4 symmetrical form, so to make so that a support surface is provided on both sides of the rail.

Also in the further variant of a mounting part 120 according to the FIGS. 6a to 6c a symmetrical configuration is provided. Here, the manner of jamming the mounting member 120 to the rail foot can now be more closely recognized. The claws 142 of the two arms 140 are in this case extended laterally and have corresponding through openings 150 (see FIG. 5a ). These openings 150 are penetrated by an elongated threaded bolt 151, which cooperates with a corresponding nut 152. By tightening the threaded bolt 151 so then the two arms 140 are pulled toward each other and jammed in accordance with the rail. The effort for mounting the mounting member 120 is thus slightly higher than in the variants of FIGS. 2 to 4 with the tension springs. On the other hand, now the assembly of a single mounting part 120 is sufficient to provide a support surface on both sides of the rail.

Furthermore, in the variant of FIGS. 6a to 6c also provided an adjustment of the inclination of the support surface. However, this is not done via a corresponding inclination of the foot sections but via a corresponding attachment of the support plate 147 on the bolt 146. A pivotal mounting of the support plate 147 is ensured by a screw 155, so that again a desired adjustment can be made. This type of attachment of the mounting plate could be used in the above-described embodiments of the mounting parts - possibly even in addition to the adjustable arrangement of the foot areas - to basically ensure a horizontal orientation of the support plates.

Ultimately, the present invention thus provides the opportunity to create running surfaces in track systems in a very simple and fast way.
