The invention relates to a portable rail barrier for separating a spatial area from a hazardous area adjoining the spatial area of a track having at least two parallel rails, with at least one support element which has a first and a second linear component, the two being connected to each other, the first component having two ends, the first end having a fastening mechanism attached for releasably fixed attachment to one of the rails and the second end being connected to the second component, and the second component having at least one retainer attached is, which supports at least one strand-shaped element with a strand longitudinal extension.

The invention also relates to a portable rail barrier for separating a spatial area from a hazardous area adjoining the spatial area of a track having at least two parallel rails, with at least two carrier elements which can be attached at a distance from one another along one of the rails of the track and each have a first and a second strand-shaped component are connected.

State of the art

In rail traffic, tracks that are used and represent a danger area must be secured with track barriers if work is being carried out in the neighboring area. Barriers of this type are intended on the one hand to ensure safe train operation in the construction site area and on the other hand to ensure safety on the construction site during train operation. In particular, it is important to prevent workers from accidentally entering the hazardous area.

Known portable track barriers have two posts (vertical components) on which at least one so-called railing (top rail) and at least one intermediate rail or intermediate side protection arranged under the railing are arranged, which prevent unhindered access to the track.

In the case of rail-mounted track barriers, the posts are attached to the rail or to be attached to the foot of the rail. The fastening devices are designed and arranged in such a way that trains can run unhindered on the track. With appropriately designed fastening devices, the track barriers can also be set up in the area of switches and crossings.

The minimum requirements for such track barriers are specified in national or international/regional standards. For example, the DIN EN 16704-2-2 standard specifies not only geometric specifications, for example the height of the barrier, but also stability requirements, electrical requirements and requirements with regard to marking to be carried out. Track barriers and their associated components should in particular enable rapid assembly and dismantling. For this purpose, at least the railing rail and the intermediate rails or intermediate side protection walls should be removable without tools, for example in order to be able to evacuate a train standing on the secured track in a short time in an emergency.

But quick, unimpeded access to the track is also desirable in other scenarios, for example for the purpose of loading or unloading a train that transports material to or from the construction site.

In the pamphlet KR 10 1 590 961 B1 a track barrier fence is disclosed, which can be mounted on a track and is mounted so that it can be folded down via a hinge joint at the foot.

The pamphlet DE 10 2011 013 145 B4 discloses a modular, pivotable, low soundproofing wall, for the attachment of which a pivoted suspension is to be fastened close to the track in the ground. The noise protection wall carried by the suspension can be swiveled in an upright orientation from a position close to the track to a position further away from the track.

The pamphlet DE 10 2015 118 661 A1 discloses a mobile soundproofing device with a carrier device to which a soundproofing mat is attached. The carrier device has two horizontally oriented, length-adjustable cantilevers, each of which is attached to the track by means of foot elements. To adjust the length, the booms each have two round tube sections that can be moved telescopically relative to one another and that can be secured in different positions relative to one another. The movable parts of the cantilevers facing away from the track each merge into a vertically oriented support rod. Adjacent support rods along the track are connected via two crossbeams, to which the soundproofing mat is attached.

The pamphlet WO 95/34719 A1 discloses a clampable device for fastening a frame of a track barrier to a profile of a laid rail profile strand.

The clampable device has a receptacle on the side facing away from the track, in which a rectangular hollow tube section is stored. A frame, which also has a vertically oriented section, is inserted telescopically into these and secured at a selectable distance from the track by means of a clip. Neighboring frames along the track are connected in the end area of the respective vertical sections with a connecting element oriented parallel to the track.

The pamphlet NL 2 011 537 C2 discloses a fence fixed to the ground near railroad tracks, having a plurality of vertical posts each connected to a railing and an intermediate rail. The vertical supports are each attached to the floor at their lower ends by means of hinge connections.

Presentation of the invention

The object of the present invention is to provide a portable track barrier of the generic type for separating a spatial area from a hazardous area adjoining the spatial area of a track having at least two parallel rails, with at least one support element which has a first and a second linear component which both being connected to each other, the first component having two ends, the first end of which provides a fastening mechanism for releasably fixed attachment to the rail and the second end being connected to the second component, and
wherein at least one holding device is attached to the second component, which mounts at least one strand-shaped component with a longitudinal extent of the strand, to be further developed in such a way that the track barrier can be erected in a very short time and brought into a state in which unhindered access to the track is possible.

The solution to the problem is given in claims 1 and 2. Features that further develop the invention in an advantageous manner are the subject matter of the subclaims and can be found in the further description, in particular with reference to the figures.

A first alternative of the portable track barrier according to the solution for separating a spatial area from a hazardous area adjoining the spatial area of a track having at least two parallel rails, with the features of the preamble of claim 1, is characterized in that the first and the second component an articulated connection is connected to a locking mechanism which, in an unlocked state, allows the second component to be pivoted about a pivot axis relative to the first component, which is oriented parallel to a first strand longitudinal extent which can be assigned to the first strand-shaped component.

A second alternative of the portable track barrier according to the solution for separating a spatial area from a hazardous area adjoining the spatial area of a track having at least two parallel rails provides at least two of the carrier elements designed according to the solution, which can be attached at a distance from one another along one of the rails of the track and in Type of a folding security fence from an erected state in a flat state are convertible.

The design of the at least one carrier element according to the solution, regardless of its ability to be combined with other carrier elements of this type to form any fence structures that can be scaled in the longitudinal direction of the fence, enables a defined, secure attachment to a rail track and also allows a quick change between a vertically protruding installation to ensure this the protective function and an associated delimitation of the area from the track and a position of the at least one carrier element lying flat on the ground next to the track, in which unhindered access to the track is possible, while the at least one carrier element lying on the ground remains firmly attached to the track .

The strand-like elements, which are fastened to the support elements with a horizontal strand length in each case for the purpose of cordoning off the area, serve in particular to protect against uncontrolled access to the track system.

The linear components are preferably in the form of railings and/or intermediate rails and are attached at a specified height relative to the track level and at a specified distance from one another along the second component of the carrier element by means of holding or fastening devices. The top rail of the rail barrier that has been erected and attached to the rail is usually referred to as the railing rail, while intermediate rails are each arranged below the railing rail. Preferably the strand-shaped components have a round, oval, square or rectangular strand cross-section with cross-sectional dimensions of 1 to 10 cm.

The strand-shaped first and second components of the carrier elements are made at least partially or completely from solid or hollow material. Hollow tubes whose cross-sectional shape is, for example, round, oval, square or rectangular are suitable as the preferred starting material.

In a preferred embodiment, the respective second component can be assigned a second longitudinal strand extension, which encloses a fixed angle with the longitudinal strand extension of the first component, to which it is connected via the articulated connection, which should be in the range between 70° and 110°, preferably 90° ° is. Ideally, the first component, which is connected to a rail at the end, lies horizontally on the ballast bed floor directly next to the tracks. In this case, it is advantageous to choose an angle of 90°, especially since the railing rail is positioned as far above the track floor as possible. However, the ground gradients often deviate from the horizontal due to the ballast bed and fall downwards with increasing distance from the tracks. In this case, it is advantageous to select the angle to be less than 90° in order to ensure that the second linear component is aligned as vertically as possible despite the first linear component of the support element resting sloping on the bottom of the ballast bed. In a particularly advantageous manner, the first and second strand-shaped components are connected in addition to the articulated connection according to the solution in each case via a releasably fixed mechanism, by means of which the above-described angle can be individually selected to compensate for local ballast bed shapes. For example, snap-in or plug-in connection mechanisms are suitable for this.

The advantage of the portable track barriers according to the invention is that to temporarily make the track accessible, the support elements and bars do not have to be laboriously dismantled, but that only the joint connection(s) must be unlocked, so that the or the second Components, in particular including the bars, can be pivoted and preferably placed on a floor area directly or indirectly adjacent to the track. Time-consuming assembly work is also eliminated when the track barrier is restored; it is only necessary to erect and lock the second component(s) again.

Ways of carrying out the invention, industrial applicability

Fig. 1a, b show a preferred embodiment of the solution according to the invention, portable track barrier 1, which is attached along a track system 110 for spatial demarcation or barrier. Fig. 1a presents a side, Fig. 1b shows a top view of the track barrier 1 arranged on the track system 110 and erected vertically.

The track barrier 1 comprises two support elements 2, 2' attached along a rail 110, each of which has a first 10, 10' and a second 20, 20' linear component. The respective first strand-shaped component 10, 10', see Fig. 1b , is fixed on one end via a known joining mechanism 60, 60' to a rail 110 of the track system 100 and is otherwise flush with the ballast bed adjoining the rail 110 to the outside. The respective second linear component 20, 20' is connected to the first linear component 10, 10' via a lockable articulated connection 30, 30'. In the locked state of the joint connection 30, 30′, the second linear component 20, 20′ protrudes vertically over the respective first linear component 10, 10′, according to the illustration in FIG Figure 1a .

Between the respective second components 20, 20' there also extend two linear elements 3, 4 in the form of a railing rail 3 and an intermediate rail 4, which are each attached to the second component 20, 20' by means of holding devices 40, 40' and 41, 41'. are attached.

With the help of the articulated connection 30, 30', the second components 20, 20' of the carrier elements 2, 2' can be pivoted out of the vertically erected position shown, after a joint lock has been released, into a position close to the ground. The respective second components 20, 20', together with the linear elements 3, 4 connected to them, can preferably be pivoted in such a way that they come to lie on top of or next to each other on the ballast bed floor next to the rail 110, as is shown in Figure 1c is indicated.

Fig. 1b shows the portable track barrier 1 in the erected state next to the rails 110, 120 of the track 100 and the first linear elements 10, 10' of the carrier elements 2, 2', which are each arranged on the rail 110 via the joining mechanism 60, 60'. The joining mechanism 60, 60′ is designed in each case in such a way that the longitudinal extension A1 of the respective first component 10, 10′ encloses an angle of 90°±15° with the rail 110 when it is mounted on the rail as intended.

1c shows a top view of the portable track barrier according to the invention in the unlocked state and lying flat on the ballast bed. The second components 20, 20' each have two straight component sections 22, 22' and 23, 23', which are each arranged at an angle to one another.

the figures 2a and 2 B show different embodiments for the formation of the carrier element 2, 2 '.

In Figure 2a the first component 10 and the second component 20 are each formed in a straight line, for example from a square tube, and enclose an angle α of 90° ± 20°, preferably 90° ± 10°. The articulated connection 30 is designed as a single-axis pivot bearing, with a pivot axis S, which is oriented parallel to the longitudinal extension A1 of the first component 10 . The bearing fork 31 of the single-axis pivot bearing is fixedly arranged on a side surface of the first component 10 in the form of a strand.

This in Figure 2b In contrast, the first component 10 shown has two components 11 and 12 that can be slid into one another telescopically, by means of which the distance between the second component 20 and the rails 3, 4 arranged thereon from the track can be variably adjusted. The first component 10 can be locked in the respectively required length by means of a safety device 13 . Furthermore, the second component 20 has three component sections 21, 22, 23, of which the third component section 23 has two comprises components 23.1, 23.2 that can be slid into one another telescopically and can be fixed in a desired position with a pin-shaped securing means 27.

In accordance with railway safety requirements, an effective height of 90 cm must be achieved with the aid of the second component 20, i.e. vertical extension. If there are additional requirements for a greater effective height, it is advisable to place a rod-shaped or tubular extension on the upper end of the component section 23, along which a corresponding holding device is attached for attaching a railing post.

The first component section 21 of the second strand-like component 20, 20' has in each case a strand longitudinal extension A2.1 and a pivot eye through which the pivot axis S runs. The longitudinal extent A2.1 of the strand is preferably oriented orthogonally to the longitudinal extent A1 of the first component 10, i.e. the angle α is 90° ± 20°, preferably 90° ± 10°.

The first component section 21 is adjoined at an angle β, preferably 120°≦β≦150°, particularly preferably 130°≦β≦140°, the second component section 22 with a strand longitudinal extension A2.2. The third component section 23 has a strand longitudinal extent A2.3, which is oriented parallel to the strand longitudinal extent A2.1 of the first component section 21.

In the case of in Figure 2b illustrated embodiment of the strand longitudinal extension A2.3 of the third component section 23, which is the longest component section of the second component 20.

In this case, too, the components of the first component 10 and/or the second component 20 are made from a hollow tube material, in particular from a square or polygonal tube.

After being attached to a rail by means of the joining mechanism 60, the first linear component 10 rests directly on a ballast bed. Ideally, the first linear component 10 extends horizontally, whereby the maximum height of the track barrier 1 is determined by the length of the second linear component 20 and the position of the handrail 3 attached to the second linear component 20 . The ballast bed often falls away as the distance from the rail increases, as a result of which the first linear component 10 also falls away from the rail, so that ultimately the elevation of the railing spar 3 in relation to the track level decreases. In order to counteract this orography-related lowering of the track barrier 1, a further preferred embodiment provides, in addition to the articulated connection 30 according to the solution, a releasably fixed mechanism 70, which can preferably be designed in the form of a snap-in or plug-in connection mechanism in order to compensate for the angle between the first and second component 10 , 20 to create such that the strand longitudinal extension of the second strand-like component is always oriented vertically regardless of the position of the first strand-like component 10. The mechanism 70 can be, for example, in the figures 2a and 2 B indicated areas along the second component 20 integrate.

Furthermore, in the figures 2a and 2 B a locking mechanism 50 indicated on the pivot bearing 30, which prevents uncontrolled pivoting of the second component 20 from the upright position.

In Figure 3a a preferred embodiment of the pivot bearing 30 is shown. A bearing fork 31 with fork walls 32 and 33 lying opposite one another is arranged on an end region of the first component 10, in particular of the extendable component 12. The fork walls each have a bore 39', 39", in which the bearing axle element 35 is mounted, for example in the form of a bearing pin. The bearing pin is secured against axial slipping by means of safety devices known per se, such as safety rings, safety pins or cotter pins The second component 20 has a first component section 21, preferably made of solid material, with a through-hole as a pivot eye 25 is provided. The pivot axis S coincides with the axis of symmetry of the bearing axis element 35 and the through bore or the pivot eye 25 .

Figure 3b shows a sectional view through the first component section 21, from which the swivel eye 25 and the bearing axle element 35 mounted therein can be seen.

The bearing fork 31 has, as in Figure 3a indicated, a fork rear wall 34, via which the bearing fork 31 is attached to a side surface of the first component 10, for example by means of a screw or welded connection. Alternatively, the fork walls 32, 33 as in 3c be attached directly to a side surface of the first component 10.

In the Figures 3c and 3d the second component 20, or at least its first component section 21, is made of a hollow material, with a bore 28, 28' being made in each of two opposite walls 21', 21" of the hollow material. In this case, a bearing bushing 24 serves as the pivot eye 25 , which either extends between the two opposite walls 21', 21" of the hollow material and is aligned with the bores 28, 28' or, as shown here, is inserted into the bores 28, 28'. A cylindrical section of a headless screw 35.1, for example, serves as the bearing pin 35, which is guided through the openings 39', 39'' in the fork walls 32, 33 and through the bearing sleeve 24 and is secured with a nut 35.2. 3d shows a sectional view through the second component 20 in the region of the pivot bearing 30, from which both the bearing sleeve 24 and the bolt 35 can be seen.

In the figures 3a and 3c the locking mechanism 50 is indicated as a locking pin 51 which engages in an opening 26 in the second component 20, in particular in the first component section 21.

In Figure 4a An alternative embodiment of the configuration of the locking mechanism 50 is shown in order to reliably prevent the second component 20, 20' from pivoting relative to the first component 10, 10' about the pivot axis S. The locking pin 51 is attached via a spring 53 directly or indirectly to one of the fork walls, here the fork wall 33 . The restoring force F of the spring 53 holds the locking pin 51 in the opening 26 of the second component 21. To unlock, the locking pin 51 must be pulled out of the opening 26 in the second component 20 against the restoring force F of the spring 53. For simplified handling, the locking pin 51 has an enlarged head as the traction means 52 .

In Figure 4b Another alternative embodiment of the locking mechanism 50 is shown. In this case, the locking pin 51 has a radially projecting locking contour 59 on the head 52 . For locking, the locking pin 51 is pressed against the restoring force F of the spring 53 into the opening 26 in the second component 20 . By rotating the locking pin 51, the locking contour 59 engages in a locking contour 58 arranged on the fork wall 33 and has a counter-contour, comparable to a bayonet connection. When the locking pin 51 is released, the spring 53 presses the locking contour 59 against the locking contour 58 and thus secures the locking pin 51 in the bore 26 of the second component 20.

In the Figures 4c and 4d is a preferred embodiment of a locking mechanism according to in Figure 4a shown principle. On the head 52 of the locking pin 51 there is a locking lug 54 which extends parallel to the longitudinal direction of the locking pin and which, in the locked state, engages in a counter-contoured recess 56 of a counterpart 55 attached to the fork wall 33 or is held by the restoring force F of the spring 53. According to Figure 4c , the locking pin 51 engages in the opening 26 of the second component 20 in this position.

For unlocking, the locking pin 51 is pulled back against the spring force F of the spring 53 to such an extent that the locking pin 51 no longer engages in the bore 26 and the detent 54 no longer engages in the recess 56 .

In order to hold the locking pin 51 in the unlocked position, it is rotated about its longitudinal axis L until the detent 54 is supported on a section of the counterpart 55 adjoining the recess, which is at a correspondingly greater distance from the second component 20.

In the Figures 5a, b shows a preferred holding device 40 in two different views (two representations rotated by 90° around the longitudinal extent of the strand of the second component 20), representative of the other holding devices 40', 41, 41', which are designed in the same way. The holding device 40 has a clip mechanism 44 into which the at least one strand-shaped element 3, 4 can be latched. The receiving contour 45 of the clip mechanism 44 is adapted to the cross-sectional shape of the linear element 3, 4 to be received. For attaching the holding device 40, the second component 20 has a tab 46 protruding laterally beyond the strand-like second component 20, for example in the form of a rectangular sheet metal section which has a bore 47 oriented parallel to the pivot axis S.

The holding device 40 is preferably rotatably mounted relative to the second component 20 . For this purpose, the holding device 40 has a cylindrical section 42 which is mounted in the bore 47 of the bracket 46 and serves as a rotary shaft for rotating the holding device about the axis of rotation D. The cylindrical section 42 is directly or indirectly connected to the clip mechanism 44 . The cylindrical section 42 preferably projects completely through the bore 47 . A securing element, for example a securing ring 43 , is arranged on the rearwardly protruding section 49 of the cylindrical section, which secures the holding device 40 against unintentional release from the bore 47 .

The rotatable mounting of the holding devices 40, 40', 41, 41' allows the respective second component 20,20' in the unlocked state of the joint connection 30, 30' together with the bars 3, 4 attached thereto can be pivoted. It is not necessary to dismantle the bars 3, 4 before pivoting.
