Description

The invention relates to a track protection fence system according to the preamble of claim 1.

To protect (temporary) track construction sites, track protection fences or track body protection fences are used in railway traffic to prevent unwanted intrusion into a track area, for example intrusion into the area of a neighboring track that continues to be used. The track protection fence systems, which include not only the track protection fence but also its holder, must be securely attached in the area of the track systems and fixed in such a way that, for example, the track protection fence is securely held even when trains are passing at high speeds or in storms. In particular, in the case of track protection fences that are only to be temporarily attached to a track system, these or the holders of the track protection fences are often attached to the track systems via fastening elements that can be detachably attached to a rail of the track system. The fastening elements are fixed in particular on a rail, in particular its rail base, or on a threshold on which the rail is attached. Especially when attaching a track protection fence system to a track system with a conductor rail, such as when attaching it to subway or S-Bahn rails, sufficient electrical insulation of the track protection fence or the track protection fence system is required to ensure that the current is carried and thus possible accidents in the event of contact with these to prevent.

From the German utility model DE 20 2005 008 225 U1 is a track body protection fence that can be attached to a rail with several cross bars that form the actual track protection fence. The cross bars are suspended in an insulating suspension on an arm that is attached to the rail via a rail foot bracket. The EP 0 708 204 A also shows a generic track protection fence system.

The object of the invention is to provide a track protection fence system that enables simple, quick, safe and detachable attachment to a track system and has reliable electrical insulation.

The invention solves these problems through a track protection fence system with the features of claim 1. Appropriate refinements and advantageous developments of the invention are specified in the subclaims.

The track protection fence system according to the invention comprises a track protection fence having at least one fence strut, preferably two, an upper and a lower fence strut, and at least one track protection fence holding system, preferably several track protection fence holding systems, via which the track protection fence can be attached to a track system. The track protection fence holding system includes a fence holder for holding the at least one fence strut, a fastening element that can be attached to a track system and a fixing system for fixing the fence holder on the fastening element. The track system to which the fastening element can be attached includes, in addition to at least one rail, at least one threshold and/or a slab track and a rail fixation, via which the rail is fixed to the threshold or the slab track.

According to the invention, the at least one fence strut of the track protection fence, which preferably runs horizontally or parallel to a rail of the track system, has at least two spars connected via an electrically insulating spar connector and the fixing system has an electrically insulating insulating connector piece, in particular one that can be attached to the fastening element or directly with it connectable insulating connector piece. This ensures that the track protection fence system is double insulated, so that, especially in the case of a track system with a conductor rail, voltage transfer across the entire track protection fence is reliably prevented even if one of the insulation fails. In addition, isolated rail joints can be bridged using a track protection fence system, especially those attached to them Track protection fence brackets, which are connected to each other via the fence struts, are prevented. The spar connectors and the insulating connector piece can in particular be formed from glass fiber reinforced polyamide 6, in particular from 30% glass fiber reinforced polyamide 6 (PA6 GF30), or from another electrically insulating material, in particular an electrically insulating plastic.

The fence strut preferably comprises more than two bars and more than one electrically insulating bar connector, with adjacent bars each being connected via an electrically insulating bar connector. According to the invention, the spar connectors can be at least partially inserted into the two spars connected via these spars and can be fixed, in particular via locking pins that can be inserted into corresponding openings in the spars and the spar connectors. This makes assembly particularly easy and quick, and the fence struts can also be dismantled quickly.

In an advantageous embodiment, the fixing system comprises a first connecting element that can be connected to the insulating connector piece, a second connecting element that can be connected to the fence holder, and a connecting piece via which the first connecting element and the second connecting element can be connected and fixed at different distances from one another. The connecting piece can be at least partially inserted into the first and second connecting elements and guided therein. Depending on the respective use of the track protection fence, a corresponding distance between the track protection fence or the fence bracket and the track system or the rail to which the fastening element is secured can be adjusted via the connecting piece. By constructing the fixing system with the individual elements, it is possible to attach and fix the fence bracket to the fastening element, which can in particular be attached to a track system independently of the fence bracket and the fixation system, in a simple and quick manner.

In a preferred embodiment, the track protection fence holding system comprises a support foot which can be connected to the fence holder and/or is guided in the fence holder for supporting the fence holder on a surface. In particular, the support foot can be fixed at different positions or at different heights relative to the fence holder. In addition to supporting the fence bracket or a track protection fence attached to it, the support foot makes it possible to absorb vibrations that occur, in particular from trains traveling on the tracks or adjacent tracks. In particular, the height adjustability of the support foot relative to the fence holder makes it possible to advantageously place the support foot on a surface, regardless of unevenness in the surface.

In an advantageous embodiment, the fence holder can have at least one holding receptacle for holding the at least one fence strut. The fence brackets preferably have two holding receptacles, an upper holding receptacle for holding an upper fence strut and a lower holding receptacle for holding a lower fence strut of a track protection fence having an upper and a lower fence strut. The fence struts can preferably be placed on the holding receptacles and secured in them via a preferably foldable locking element arranged on the holding receptacles. This ensures that the fence struts can be inserted and removed quickly and that the fence struts can be securely fixed in the holding receptacles. In particular, the closing element also reliably prevents the fence struts from being unintentionally removed from the holding receptacles, for example due to a shock from a worker, storms, vibrations or the wind from passing trains.

In a preferred embodiment, the fastening element has a coupling element, in particular a coupling tube, on which the electrically insulating insulating connector piece can be arranged, in particular inserted into it and/or fastened therewith. On the one hand, this ensures a simple connection of the fixation system to the fastening element. On the other hand, the arrangement of the insulating connector piece means that it is directly attached to the fastening element The (remaining) fixation system and the fence bracket are insulated so that there is no danger even if they come into contact.

The fastening element preferably has at least a first leg and a second leg spaced apart from it and running parallel to it, a middle part which connects the two legs to one another, and a coupling element for connection to the fixing system. Particularly preferably, the legs each have a locking bolt receiving opening at a front or outer end remote from the middle part, in particular a hole into which a locking bolt can be inserted to secure the fastening element to the track system. The locking bolt receiving openings are arranged on the legs in such a way that a locking bolt that can be inserted into the locking bolt receiving openings is between a rail web of the rail of the track system and a rail fixation that fixes the rail, in particular a fastening screw and / or a tension clamp, via which the rail is attached to a threshold, for example a on a sleeper arranged on a ballast bed, or on a solid roadway, in which the rails are mounted directly on a superstructure made of concrete or asphalt or on rail support points arranged thereon. Using the locking bolt receiving openings or the locking bolts that can be inserted into them, it is possible to quickly and reliably secure the fastening element to the track system and then also to quickly unlock and remove the fastening element from the rail or the track system. The simple and rapid securing and unlocking of the fastening element on a rail is particularly advantageous when attaching track protection fences that are only temporarily attached to a track system.

Particularly preferably, the fastening element has a substantially U-shaped configuration, with the legs in particular enclosing a substantially right angle with the middle part. The U-shaped design and the legs spaced apart from one another make it particularly possible to attach it of the fastening element on different types of thresholds, the thresholds being able to be arranged in particular between the legs.

The fastening element particularly preferably consists of the middle part, the coupling element and the legs connected to it, in particular firmly connected. Further components, in particular components that are not firmly connected to the legs or the middle part, which make the handling of the fastening element or its attachment to a track system more difficult or could impair its stability, are not required.

In an advantageous embodiment, the legs of the fastening element each have a receptacle for at least partially receiving a rail foot of the rail or for at least partially receiving the rail foot and a rail foot fastening provided for fastening a rail foot on a sleeper, for example a fastening plate, of the track system. The receptacles are arranged in particular at the front ends of the legs that are remote from the middle part. The locking bolt receiving openings are particularly preferably arranged above the receptacles on the legs. In a particularly advantageous embodiment, the legs of the fastening element each have a receptacle on an underside, in particular essentially flat, contact section which, when fastening the fastening element to a track system, is at least partially on the underside of the rail or the rail foot and / or a The rail foot fastening fastening the rail, in particular a fastening plate mounted on a threshold, is arranged. The contact section preferably rests on the underside of the rail. Using the described design of the legs of the fastening element, in addition to simply attaching the fastening element to a rail, secure fastening of the fastening element to the rail is possible. In particular, the receptacle and the contact section arranged on an underside of a rail foot and/or a rail foot fastening allow a rail to be twisted or tilted attached fastening element about an axis running parallel to the rail, i.e. tilting upwards or downwards is not possible or only possible to a limited extent.

In an advantageous embodiment of the fastening element, the legs of the fastening element each comprise a contact element that can be placed on a surface and each have a side part arranged on the contact element and having the locking bolt receiving opening, or the legs consist of these. The front end of the contact element remote from the middle part can in particular form the contact section delimiting the receptacle on an underside. In particular, the contact element can also protrude beyond the front end of the side part. The side parts can in particular be welded to the contact elements. Particularly preferably, the contact elements and/or the side parts and/or the middle part are essentially flat, in particular formed from a metal plate. Very particularly preferably, the two contact elements and the middle part are formed in one piece or from a common piece. The configurations described provide a production-technically simple, easy-to-handle and stable design of the fastening element.

In a preferred embodiment of the fastening element, the coupling element, which can in particular be a coupling tube, is designed for releasably attaching the fixing system, in particular for releasably attaching the insulating connector piece. The coupling element is preferably arranged centrally between the legs on the middle part, in particular welded to it. On the one hand, this ensures a stable design of the fastening element. On the other hand, the detachable attachment of the additional track device makes it easy to handle, especially easy to attach the fastening element to the track system. After the fastening element has been attached and secured to the track system, the insulating connector piece can simply be connected to the coupling element and fixed to it.

In an advantageous embodiment, the track protection fence system comprises a locking bolt which can be inserted into the locking bolt receiving openings of the fastening element, the locking bolt having a spring element at a first end and a securing element, in particular a tilting element, at its second end for releasably fixing the locking bolt in the locking bolt receiving openings. When a locking bolt is inserted or secured into the locking bolt receiving openings, the spring element and the securing element rest in particular on an outer side of the locking bolt receiving openings. Via the spring element and the securing element, which in particular has a locking and unlocking position, it is possible to securely fix a locking bolt inserted into the locking bolt receiving openings in these and thus securely fasten the fastening element to a track system. To move the securing element of the locking bolt inserted into the locking bolt receiving openings from a locking position to an unlocking position and vice versa, an external force must be applied against the spring element. This prevents the locking bolt from being accidentally released from the locking bolt receiving openings.

These and other advantages of the invention result from the following exemplary embodiment.

In Fig. 1 As an example, a track protection fence system 1 with several track protection fence holding systems 2 for holding a lower and an upper fence strut 80, 80 'forming a track protection fence is shown. The track protection fence holding systems 2 are each attached to a track system 3 comprising a rail 4, with the attachment to four different track systems 3-1 to 3-4 being shown as an example to illustrate the possible uses of the track protection fence holding system 2, which are shown in Fig. 1 are shown arranged in sections one behind the other in the longitudinal direction of the rail 4. This in Fig. 1 shown right track system 3-1 (first track system 3-1), shows an example of a solid track and the second to fourth embodiments 3-2 to 3-4 of the track systems 3, seen from the right, show a normal track with different sleepers 8 on which the Rail 4 is attached.

Fig. 2 and Fig. 3 show a track protection fence system 2 of the in Fig. 1 shown track protection fence system 1 in a perspective view and in a side view. In Fig. 4 is a side view of the first track system 3-1 Fig. 1 attached track protection fence system 2 shown. The track protection fence holding system 2 includes a fastening element 10, which can be secured to a track system 3 via a locking bolt 20, an insulating connector piece 30 connected to the fastening element 10, a first connecting element 40 connected to the insulating connector piece 30, a second connecting element 50, which has an in the Fig. 2 to 4 connecting piece 45, not shown, is connected to the first connecting element 40, a fence holder 60 connected to the second connecting element 50 and a support foot 70 connected to the fence holder 60. The individual components of the track protection fence holding system 2 are in the 5 and 6 and 11 to 14 shown in detail and described in more detail below. The individual interconnected components of the track protection fence holding system 2 are fixed to one another via pipe folding pins 90 or other fixing means inserted into corresponding openings in the individual components.

This in Fig. 5 Fastening element 10 shown in detail is used for releasably fastening the track protection fence holding system 2 to a track system 3. The fastening element 10 has a substantially U-shaped configuration with a first leg 11 and a second leg 11 'spaced therefrom, which has a flat middle part 12 are connected. The legs 11, 11' each consist of a substantially flat contact element 13, 13' and a side part 14, 14' which is arranged on the contact elements 13, 13', in particular welded to this side part. The middle part 12 and the contact elements 13, 13 'are in one piece, in particular formed from a metal plate. On the middle part 12, in the middle between the legs 11, 11 ', there is a coupling element 17, specifically a coupling tube with a substantially square cross section, for connection to the insulating connector piece 30 of the track protection fence holding system 2, as in particular in Fig. 3 and Fig. 4 is shown, applied, in particular welded to this.

To attach the fastening element 10 to a track system 3, the legs 11, 11' each have a receptacle 16, 16' at their front end remote from the middle part 12, for example in the form of a recess for at least partially receiving a rail foot 5 or a rail foot half Rail 4 and a locking bolt receiving opening 15, 15' arranged above the receptacle 16, 16 ', in particular a bore, into which the in Fig. 6 Locking bolt 20 shown in detail and described in more detail below can be inserted. The receptacles 16, 16' of the side parts 14, 14' are delimited on the underside by a contact section, which is formed by the front end of the contact elements 13, 13' remote from the middle part 12. The contact section or the contact elements 13, 13 'protrude in particular slightly beyond the front end of the side parts 14, 14', which is remote from the middle part 12.

The attachment of the fastening element 3 to a track system 3 is exemplified in Fig. 7 and Fig. 8 shown, in which a section of the second track system 3-2 Fig. 1 attached track protection fence holding system 2 in the area of the fastening element 10 is shown in a perspective view and in a side view. The second track system 3-2 includes, in addition to the rail 4 and the threshold 8, a rail fixation that fixes the rail 4 on the threshold 8, in particular a tension clamp 9 'that fixes a rail foot 5 of the rail 4 and a tension clamp 9' on the threshold 8 or a fastening screw 9 fixed on the threshold 8. In addition to the rail foot 5, the rail 4 includes a rail head 7, which is connected to the rail foot 5 via a rail web 6.

This in 7 and 8 Fastening element 10 shown, attached to the second track system 3-2, rests with the middle part 12 on the threshold 8 of the second track system 3-2, the threshold 8 being arranged between the legs 11, 11 '. As in Fig. 8 is shown, the receptacles 16, 16 'of the side parts 14, 14' take the rail foot 5 or the part of the rail foot 5 facing the middle part 12 Rail 4, whereby the contact elements 13, 13 'are partially guided, in particular with their front area remote from the middle part 12, on the underside of the rail 4 or the rail foot 5 and rest against it. The contact elements 13, 13' are designed in such a way that the front end of the contact element 13, 13' remote from the middle part 12 does not extend over the entire underside of the rail 4, that is, not up to the side of the rail 4 or .The rail base 5 is guided. The front end of the side parts 14, 14 'removed from the middle part 12 rests on the rail web 6 or at least close to it. The side parts 14, 14' resting on or close to the rail web 6 and the sections of the contact elements 13, 13' guided on the underside of the rail 4 prevent or at least limit upward tilting of the fastening element 10.

The fastening element 10 is secured to the rail 4 via the locking bolt 20 which can be inserted into the locking bolt receiving openings 15, 15 '. As in Fig. 7 is shown, the locking bolt 20 is arranged between the rail web 6 and the rail fixation, here the head of the fastening screw 9. The locking bolt 20 prevents the fastening element 10 from being removed from the rail 4, in particular perpendicular to the longitudinal axis of the rail 4, i.e. transversely to the direction of travel of a track vehicle guided on the rail 4.

To secure the locking bolt 20 in the locking bolt receiving openings 15, 15 ', the locking bolt 20, as in Fig. 6 is shown in detail, at a first end a spring element 21, in particular a compression spring, and at a second end a securing element 22 designed as a tilting element. The spring element 21 of a locking bolt 20 secured in the locking bolt receiving openings 15, 15' rests on an outside of a first side part 14, 14' and the securing element 22 rests on the outside of the second side part 14, 14' of the fastening element 10. To rotate the securing element 22 of a locking bolt 20 inserted into the locking bolt receiving openings 15, 15 'from the in Fig. 6 shown locking position into an unlocking position, in which the longitudinal axis of the securing element 22 runs parallel to the longitudinal axis of the locking bolt 20, or vice versa, a force must be applied against the spring element 21. This reliably prevents, in particular, unwanted rotation of the securing element 22 from the locking position into the unlocking position and thus unwanted removal of the locking bolt 20 from the locking bolt receiving openings 15, 15'.

In the Figures 4 , 9 and 10 is the attachment of the fastening element 10 to the in Fig. 1 First, third and fourth track systems 3-1, 3-3 and 3-4 shown are each shown in a side view. The fastening element 10 is attached and secured to these track systems 3-1, 3-3 and 3-4 in the same way as in Fig. 7 and Fig. 8 Fastening and securing shown on the second track system 3-2. In contrast to those in the Fig. 4 , 7 , 8th and 10 In the exemplary embodiments shown, the contact elements 13, 13 'of the fastening element 10 are located at the in Fig. 9 shown third track system 3-3 not directly on the rail foot 5 but on a rail foot fastening 95 attached to the threshold 8 or a fastening plate on which the rail 4 is arranged or fastened.

The fastening element 10 shown can be attached, secured and also detached from them in a simple and quick manner, in particular on different track systems 3.

About the coupling element 17 arranged on the middle part 12 of the fastening element 10, which, as in particular in Fig. 5 is shown is designed as a square hollow tube, which is in Fig. 11 Insulating connector piece 30 shown in detail can be connected to the fastening element 10, for example in Fig. 2 is shown. The insulating connector piece 30 can be inserted into the coupling element 17 and secured to it via a tubular folding pin 90, not described in more detail, which can be inserted into openings in the insulating connector piece 30 and the coupling element 17. The insulating connector piece 30 preferably consists of an electrically insulating material, for example a glass fiber reinforced polyamide 6, in particular a 30% glass fiber reinforced polyamide 6 (PA6 GF30). This provides electrical insulation of the track protection fence or the rest of the track protection fence holding system 2 from the fastening element 10 attached to the track system 3.

Fig. 12 shows in detail the first connecting element 40 which can be connected to the insulating connector piece 30 and is designed as a square hollow tube. About the in Fig. 13 The connecting piece 45 shown in detail, which can be inserted into the first connecting element 40 and can be guided in this, is the in Fig. 14 second connecting element 50 shown in detail can be connected to the first connecting element 40. For this purpose, the second connecting element 50 has a connecting piece receptacle 51, which is also designed as a square tube, into which the connecting piece 45 can be inserted and guided. The fixation of the first connecting element 40 with the insulating connector piece 30 and the fixation of the connecting elements 40, 50 with the connecting piece 45 also take place via pipe folding pins 90 (not described in more detail) which can be inserted into corresponding openings, such as in the Fig. 2 to 4 is shown.

To connect with the in Fig. 15 In the fence holder 60 shown, the second connecting element 50 has a fence holder receptacle 52 designed as a square tube, into which a fence holder support 61, in particular a fence holder support 61 of the fence holder 60 designed as a square tube, can be inserted and fixed in this via a tube folding pin 90 which can be inserted into corresponding openings. The fence holder receptacle 52 and the connecting piece receptacle 51 of the second connecting element 50 are connected to one another via an incline 53. In particular, the slope 53 has an angle of approximately 45° or 135° with a connecting piece 45 inserted into the connecting piece receptacle 51 and a fence holding support 61 inserted into the fence holder receptacle 52.

To hold the in Fig. 1 shown, running parallel to the rail 4 lower fence strut 80 and upper fence strut 80 'of the track protection fence, the fence holder 60 on the fence holder support 61 has an upper holding receptacle 62 and a lower holding receptacle 63. The fence struts 80, 80' can be secured in the holding receptacles 62, 62 via a closing element 64, 64', in particular a closing element 64, 64' arranged foldably on the holding receptacles 62, 63.

The fence struts 80, 80' forming the track protection fence are made up of several, in Fig. 17 spars 81 shown in detail, each with two spars 81, as in particular in Fig. 19 and in the in Fig. 20 The excerpt shown is shown above in Fig. 18 spar connectors 82 shown in detail are connected to one another. The spar connectors 82 are partially or with one side each inserted into the spars 81 and releasably fixed via locking pins 83 inserted into corresponding openings in the spars 81 and the spar connectors 82. The spar connectors 82 are in particular made of an electrically insulating material, in particular a glass fiber reinforced polyamide, for example PA6 GF30. The electrically insulating design of the spar connectors 82 prevents voltage from being carried over several spars 82 or via several track protection fence holding systems 2 holding the fence struts 80, 80 '.

To support the fence bracket 60 on a surface, the track protection fence holding system 2 includes the in Fig. 16 Support foot 70 shown in detail. The support foot 70 can be inserted into the fence holder 60 or into the fence holder support 61 and is guided therein and fixed via a tubular folding pin 90. The support foot 70 is fixed to the fence holder 60 and the fence holder 60 is fixed to the fence holder receptacle 52 of the second connecting element 50 by means of a single tubular folding pin 90, as in Fig. 3 is shown. Due to the numerous openings arranged along the longitudinal axis of the support foot 70, through which a fixation to the fence holder 60 takes place via a tubular folding pin 90, the support foot 70 can be fixed at different heights. This means that the fence bracket 60 is supported on a surface via the support foot 70 possible regardless of any unevenness or slope that may be present.

In addition to the embodiment shown in the above exemplary embodiment, numerous other configurations of the track protection fence system 1 or the individual components of the track protection fence holding system 2 are conceivable. For example, the first connecting element 40 and the second connecting element 50 can be designed to be lockable at different distances from one another via a corresponding design of these and/or the connecting piece 45 that can be inserted into them, in particular by a corresponding arrangement of the openings for the tubular folding pin 90. This makes it possible in particular to arrange the track protection fence at different distances from the track system 3 or from the rail 4. In addition to the electrically insulating spar connectors 82 and the insulating connector 30, electrically insulating coatings of the individual components of the track protection fence system 1 are also possible for further electrical insulation of the track protection fence system 1.
