Description

Technical area

The invention relates to a portable track barrier for separating a spatial area from a danger area adjoining the spatial area of a track having at least two parallel rails, with at least one carrier element which has a first and a second strand-like component, which are both connected to one another, wherein the first component has two ends, wherein a joining mechanism for releasably fixed attachment to one of the rails is attached to the first end and the second end is connected to the second component, and wherein at least one holding device is attached to the second component is that supports at least one strand-like element with a strand longitudinal extension.

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

State of the art

In the case of rail traffic, tracks that are used and represent a danger area must be secured with rail barriers if work is being carried out in the neighboring area. Such barriers 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 danger area.

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

In the case of rail-mounted track barriers, the posts are each attached to the rail or via so-called "horizontal components" and suitable fastening devices to be attached to the rail foot. The fastening devices are designed and arranged in such a way that trains can travel 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 rail barriers are specified in national or international / regional standards. For example, the standard DIN EN 16704-2-2 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 spar and the intermediate spars or intermediate side protective 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.
However, in other scenarios, too, fast, unimpeded access to the track is desirable, 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 can be folded down via a hinge joint on the foot side.

The pamphlet DE 10 2011 013 145 B4 discloses a modular, pivotable, low soundproofing wall, for the purpose of which it is to be attached close to the track, a pivoted suspension is to be fastened close to the track in the ground. The soundproofing 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.

Presentation of the invention

The object of the present invention is to provide a generic portable track 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 carrier element that has a first and a second strand-like component which both are connected to one another, wherein the first component has two ends, the first end of which provides a joining mechanism for releasably fixed attachment to the rail and the second end is connected to the second component, and
at least one holding device is attached to the second component, which supports at least one strand-shaped component with a longitudinal extension, to be further developed in such a way that the track barrier can be erected in a very short time and converted into a state in which unimpeded access to the track is possible.

The solution to the problem is given in claims 1 and 2. Features which advantageously develop the invention are the subject matter of the subclaims and 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 danger 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 second component over an articulated connection are connected to a locking mechanism which, in an unlocked state, enables the second component to pivot about a pivot axis relative to the first component which is oriented parallel to a first longitudinal extension that 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 danger 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 Kind of a foldable security fence can be converted from an erected state into a state lying flat on the ground.

The design of the at least one support element according to the solution, regardless of its ability to be combined with other such support elements for the formation of any fence structures that can be scaled in the longitudinal direction of the fence, enables, on the one hand, a defined secure attachment to a rail track and, on the other hand, enables a quick change between a vertically towering installation for guarantee purposes the protective function and an associated area delimitation to the track and a position of the at least one support element lying flat on the ground next to the track, in which unimpeded access to the track is possible, while the at least one support element lying on the ground remains firmly attached to the track .

To protect against uncontrolled entry to the track system, the string-shaped elements are used in particular, which are attached to the support elements for the purpose of blocking off the area, each with a horizontal length of the string.

The strand-like components are preferably designed in the form of handrails and / or intermediate spars and are attached at a predetermined height relative to the track level and at a predetermined distance from one another along the second component of the carrier element by means of holding or fastening devices. The uppermost spar of the rail barriers that have been erected and fastened to the rail is usually referred to as the handrail, whereas intermediate spars are each arranged below the handrail. 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-like 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 round, oval, square or rectangular, for example, are suitable as a preferred starting material.

In a preferred embodiment, the respective second component can be assigned a second longitudinal extension that encloses a fixed angle with the longitudinal 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. In the ideal case, the first component connected at the end with a rail rests 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 this means that the handrail is positioned a maximum of far above the track floor. Often, however, the ground inclines 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 choose the angle smaller than 90 ° in order to ensure that the second strand-shaped component is oriented as vertically as possible despite the first strand-shaped component of the carrier element lying slopingly on the gravel bed floor. In a particularly advantageous manner, in addition to the articulated connection according to the solution, the first and second strand-like components are each connected via a releasably fixed mechanism, by means of which the angle described above can be selected individually to compensate for local ballast bed shapes. For this purpose, latching or plug connection mechanisms, for example, are suitable.

The advantage of the portable track barriers according to the invention is that the support elements and spars do not have to be laboriously dismantled to temporarily make the track accessible, but that only the articulated connection (s) have to be unlocked, so that the second Components, in particular including the spars, can be pivoted and preferably placed on a floor area directly or indirectly adjacent to the track. Even when the track barriers are restored, there is no need for time-consuming assembly work; only the second component or components have to be erected and locked again.

Ways to carry out the invention, commercial applicability

Fig. 1a, b show a preferred embodiment of the portable track barrier 1 according to the solution, which is attached along a track system 110 for the spatial delimitation or barrier thereof. Fig. 1a represents a side, Figure 1b is a plan view of the arranged on the track system 110 and erected vertically track barrier 1.

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 'strand-like component. The respective first strand-like component 10, 10 ', see Figure 1b , is releasably fixed to a rail 110 of the track system 100 on one end via a known joining mechanism 60, 60 'and is otherwise flush with the ballast bed adjoining the rail 110 to the outside. The respective second strand-shaped component 20, 20 'is connected to the first strand-shaped component 10, 10' via a lockable articulated connection 30, 30 '. In the locked state of the articulated connection 30, 30 ', the second strand-shaped component 20, 20' protrudes vertically over the respective first strand-shaped component 10, 10 ', according to the illustration in FIG Figure 1a .

In addition, two string-shaped elements 3, 4 in the form of a railing beam 3 and an intermediate beam 4 extend between the respective second components 20, 20 ', which are attached to the second component 20, 20' by means of holding devices 40, 40 'or 41, 41'. are attached.

With the aid of the articulated connection 30, 30 ', the second components 20, 20' of the carrier elements 2, 2 'can be pivoted from the illustrated vertically upright position into a position close to the floor after a joint lock has been released. The respective second components 20, 20 ′ together with the strand-like 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 one another on the gravel bed floor next to the rail 110, as shown in FIG Figure 1c is indicated.

Figure 1b shows the portable track barrier 1 in the erected state next to the rails 110, 120 of the track 100 and the first strand-like 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 such a way that the strand longitudinal extension A1 of the respective first component 10, 10 ′ encloses an angle of 90 ° ± 15 ° with the rail 110 when properly mounted on the rail.

Figure 1c shows a plan 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 Fig. 2a the first component 10 and the second component 20 are each designed in a straight line, for example made of 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 extent 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 strand-like first component 10.

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

In accordance with railway safety requirements, it is necessary to achieve an effective height of 90 cm 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 handrail.

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

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

The above-mentioned strand length A2 of the second component corresponds in the case of FIG 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.

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

The first strand-like component 10 rests directly on a ballast bed after being fastened to a rail by means of the joining mechanism 60. Ideally, the first string-like component 10 extends horizontally, whereby the maximum height of the track barrier 1 is determined by the length of the second string-like component 20 and the position of the handrail 3 attached to the second string-like component 20. Often the ballast bed drops off as the distance from the rail increases, as a result of which the first strand-like component 10 also drops away from the rail, so that ultimately the elevation of the handrail 3 relative to the level of the track decreases. In order to counter 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 latching or plug-in connection mechanism in order to compensate for the angle between the first and second component 10 To create 20 in such a way that the longitudinal extension of the second strand-shaped component is always oriented vertically regardless of the position of the first strand-shaped component 10. The mechanism 70 can, for example, be attached to the Figures 2a and 2 B Integrate indicated areas along the second component 20.

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 erected position.

In Fig. 3a a preferred embodiment of the pivot bearing 30 is shown. A bearing fork 31 with fork walls 32 and 33 opposite one another is arranged at 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, for example in the form of a bearing pin, is mounted. The bearing pin is secured against axial slipping by means of securing devices known per se, such as securing rings, securing pins or split pins The second component 20 has a first component section 21, preferably made of solid material, with a through-hole as a swivel eye 25 is provided. The pivot axis S coincides with the axis of symmetry of the bearing axis element 35 and the through hole or the pivot eye 25.

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

The bearing fork 31 has, as in Fig. 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 FIG Figure 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 opposing walls 21', 21 "of the hollow material , 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 shaft screw 35.1, for example, 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, serves as the bearing pin 35. Fig. 3d shows a sectional view through the second component 20 in the area 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 for the configuration of the locking mechanism 50 is shown in order to reliably prevent pivoting of the second component 20, 20 ′ relative to the first component 10, 10 ′ about the pivot axis S. FIG. The locking pin 51 is fastened directly or indirectly to one of the fork walls, here the fork wall 33, via a spring 53. 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 a pulling 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 protruding latching 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 turning the locking pin 51, the locking contour 59 engages in a counter-contoured locking contour 58 arranged on the fork wall 33, 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 the 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, when locked, 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 this position in the opening 26 of the second component 20.

To unlock, 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 keep the locking pin 51 in the unlocked position, it is rotated about its longitudinal axis L so that the locking lug 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 a preferred holding device 40 is shown in two different views (two representations rotated by 90 ° around the longitudinal extension of the second component 20), representing the further 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-like element 3, 4 can be latched. The receiving contour 45 of the clip mechanism 44 is adapted to the cross-sectional shape of the strand-like element 3, 4 to be received. To attach 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 mounted rotatably 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 connects directly or indirectly to the clip mechanism 44. The cylindrical section 42 preferably extends completely through the bore 47. A securing element, for example a securing ring 43, is arranged on the rearward protruding section 49 of the cylindrical section, which secures the holding device 40 against unintentional detachment from the bore 47.

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