Abstract

L'invention concerne un support de rails conducteurs pour le métro et pour les tramways, consistant en un support composé de pièces plastiques enserrant par liaison de forme un rail conducteur placé à une distance définie d'un rail de roulement. Le support de rails conducteurs et le rail de roulement s'appuient sur des traverses. Le support comporte au moins deux profilés en matière thermoplastique se tenant mutuellement par liaison de forme, de préférence en polyamide renforcé par fibres de verre avec addition de noir de carbone. La surface du support peut être munie de rebords pour éviter un flux de courant. Le support ne nécessite pas de pièces métalliques pour fixer le rail conducteur. Ce dernier est bloqué par des profilés de serrage contre une partie du support, formée en complémentarité. Le support peut reposer sur un étai de rails conducteurs pour être monté sur des trverses de rails et d'aiguillage normalisées, de longueur normale. Un support intermédiaire spécial pour les étais peut être monté avec les moyens de fixation des rails ou à même la traverse, de manière qu'il ne soit pas nécessaire de remplacer la traverse par des traverses spéciales longues, adaptées au support de rails conducteurs. L'étai de rails conducteurs se compose d'un profilé plastique ressemblant à une poutre en treillis, qui s'étend à partir de la traverse sous forme d'un module effilé en forme de C ayant un couple de résistance élevé.The invention relates to a conductor rail support for the metro and for trams, consisting of a support composed of plastic parts enclosing by form connection a conductor rail placed at a defined distance from a rolling rail. The conductor rail support and the running rail rest on crossbeams. The support comprises at least two sections of thermoplastic material holding each other by form connection, preferably of polyamide reinforced with glass fibers with the addition of carbon black. The surface of the support can be provided with edges to prevent current flow. The bracket does not require metal parts to attach the conductor rail. The latter is blocked by clamping profiles against a part of the support, formed in complementarity. The support can rest on a strut of conductive rails to be mounted on standard rail and switch sleepers, of normal length. A special intermediate support for the props can be mounted with the means of fixing the rails or directly on the crosspiece, so that it is not necessary to replace the crosspiece with special long crosspieces, suitable for supporting conductor rails. The conductor rail prop consists of a plastic profile resembling a lattice girder, which extends from the sleeper as a tapered C-shaped module with a high resistance torque.

Busbar support

Description:

The invention relates to a busbar support, in particular for subways and suburban trains, with a holder composed of plastic parts for positive engagement of a busbar arranged at a defined distance from a travel rail, the busbar supports and the travel rail being supported on sleepers, and the use of certain materials for busbar supports.

Such busbar supports are required for U or S-Bahn 15, the towing vehicles pick up current not from the overhead line but from busbars running parallel to the track. Depending on how the vehicle taps the power, the power rails are touched from above or from below by the power transmission elements. Accordingly, the 20 busbar supports are equipped with brackets that either support the busbar upright or hold it hanging.

Depending on the type of sublimation of the rails used with concrete, wood or steel sleepers, according to the state of the art, the busbar supports are designed differently and are composed of different materials. The purpose of the material selection is the need

'^''^' to electrically isolate the track from the power track.

30 Systems (DE-30 18 907-C2; DE-30 18 907-C2; DE-33 31 615 AI) made of a combination of many materials are widespread, in which the wooden or concrete sleeper with metal trestles are connected, at the upper end of which an insulator made of porcelain or PVC is arranged, in front of which metal holding claws for the busbar are in turn attached. Due to the large number of different individual parts, assembly and replacement bedding are complex. PVC is also known as an environmentally harmful, non-recyclable material. According to the state of the art, the claws for holding the current rail foot can only clamp the foot (top of the rail foot) or, in one case, clamp the rail foot as a whole by combining two metal elements. This bracing makes it difficult to simply align the busbar in a predefined manner. From practice, a particular shape of the insulator for a Stromschienenabgriff from above is known in which the entire busbar support made of a porcelain dish piece which is screwed directly on the threshold, there ^'.

Furthermore, busbar supports are known from practice, in which the insulator contains an intermediate layer made of rubber or leather towards the busbar in order to protect the sensitive porcelain of the insulator against mechanical damage resulting from operating stress. Such a porcelain insulator has rib-shaped reinforcements on the insulator body between the busbar receptacle and its attachment to the support bracket. This attachment consists of a screw that pulls the insulator against the metal bracket with the interposition of a washer. The height of the screw connection can be adjusted from above using a vertically arranged spindle nut. I In the case of another isolator consisting of plastic parts, a first angled part is fixed to a metal mounting bracket with a screw bolt and nut. A height adjustment is possible because the screw bolt is in an elongated hole on the bracket sits. At its other end, this' first angle profile has a nose for one-sided grip under the rail foot of the busbar. In its middle part it has holes through which a bolt-nut screw connection engages, which in turn locks a further plastic cover profile that engages around the other side of the rail foot over the conductor rail. The base of the conductor rail has no direct contact with the plastic, but slide rails are arranged between the contact surfaces on the plastic and the congruent contact surfaces at the base of the conductor rail, "which in turn are held in place by screw connections in the plastic parts. These slide rails are obviously necessary to avoid damage due to damage Avoid operating stress on the busbar on the plastic holders.

All systems according to the state of the art are complex to assemble and obviously require protection against mechanical damage due to operational stress which acts on the busbar. The busbar holder made of plastic has a large number of metallic parts in the immediate vicinity of the busbar, which gives rise to the risk that current flow from the busbar, for example over the surface of the plastic, which can be conductive due to contamination or wetting with liquids, is an electrochemical 'attack on the fasteners or current is transmitted to the bracket -. A current flow to the support bracket is not permitted, especially if steel sleepers are to be used for the track. Porcelain holders are also very susceptible to impact and friction. The busbar support for the bracket on the Busbar supports are arranged in a free space outside the clearance profile, which includes both the vehicle and the pantograph. The supports according to the state of the art are made of plastic, steel or light metal and are attached to particularly long special sleepers, which protrude from one side of the rail base by up to 1 m, regardless of the type of sublimation used for the travel rails with concrete, wood or steel sleepers. It is therefore not possible to retrofit standardized, long track or turnout sleepers without exchanging the sleepers, which are intended to hold the support of the busbar support, for extended sleepers.

In practice, the supports of the busbar supports are designed as C-shaped or angled arcs describing a quarter circle. As a rule, the supports consist of profiles of the same cross-section. The choice of material for the support depended on the type of sublimation, again taking care that the running rail is electrically insulated from the current rail.

The invention is therefore based on the problem of creating a busbar deburrer which can be easily and quickly assembled without additional metal parts in the busbar area and which offers high insulation values

Operating load cannot be adjusted or damaged, can be used for standardized track and point undershoot, and can be manufactured easily and inexpensively.

According to the invention, the problem is solved by claims 1, 2, 10, 15 and 16. Advantageous developments of the invention are covered in the subclaims.

The preferred holder consists of only two mutually positive profiles made of thermoplastic material, which after pre-assembly of the holder on the

Track support or on a threshold and after positioning the track simply pushed into each other, and thus keep the track permanently and reliably. In the simplest case, the holder has an integrated holding lug for one. Foot side of the current rail, while the second foot side is held in particular by a clamping profile and can be aligned, e.g. by using clamping profiles with different width side guides for the rail foot. The preferred material for such a holder or the profiles from which the holder is made is a glass fiber reinforced thermoplastic polyamide, which can be provided with a soot additive for reasons of stabilization against UV light. Polybutyl therapy and thermoplastic polyester or polyethylene have proven to be other suitable materials. The amount of glass fiber additive depends on the weight of the conductor rail to be carried and the tilting moments resulting from the operating load and acting on the holder. Of course, the shape, that is, the diameter and the ribbing of the holder, if applicable, are jointly responsible for its strength and load-bearing capacity. Overall, the holder, which is essentially made in one piece and has only additional clamping profiles for locking the busbar, is considerably stiffer than the systems according to the prior art.

The shape of the clamping profile and its positive engagement around the foot of the conductor rail and the ratio of the contact surface between the plastic profiles to the contact surfaces with the rail base ensure that the clamping profiles are held securely on the larger holding body of the holder. The friction between the plastic surfaces is greater than the friction towards the rail foot and a possibly occurring tilting moment on the conductor rail ensures greater pressing forces between the contact surfaces of the plastic parts, so that the fastening elements for the conductor rail are securely seated.

Polyamide with its extremely hard surface and high impact strength makes this material so suitable for such mounting tasks.

In a further development of the invention, the middle part of the holder acting as an insulator is conditioned in addition to obstructing a possible current flow. This can be done by making the surface of the holder very smooth, so that minimal adhesion of dirt and liquid is possible and / or the surface - better: the surface line - of the holder is artificially enlarged by ribs in this part of the holder be arranged that completely enclose the holder. Due to the material, current can only flow essentially over the surface of the holder; however, the rib arrangement extends the path for the current so considerably that no current flow from the conductor rail to the threshold can actually be measured due to this resistance.

In addition, depending on the form of its attachment to the threshold in the holder designed as a hollow body Fasteners integrated. This can be a screw nut cast in during manufacture of the holder or the holder is provided at its end with guide pins and flanges which give it a secure hold on the sleeper or the fastening means arranged between the sleeper and holder. In a special embodiment, with the exception of the clamping profiles, the holder and the fastening means are manufactured in one piece from thermoplastic, preferably polyamide.

The fastening means can in turn comprise means for adjusting the position of the holder, as are known from practice and can also be used here in a modified form. To improve the dismantling safety, these fasteners can be secured to prevent unauthorized adjustment or dismantling. Such fasteners are, in particular, bolts with heads that can only be loosened with special machines or special tools. The position adjustment can be done by using washers e.g. made of plastic directly on the threshold and / or by inserting a special intermediate bracket with adjustment options in the transverse direction of the rail e.g. can be realized by elongated holes and / or by a spindle-like height adjustment of the holder on the busbar support.

A separate intermediate bracket, preferably made of metal with conventional rail fastening means, is preferably used to hold the conductor rail support on a track or switch underswell with a standard length made of wood or concrete. This can consist of a steel plate welded to the ribbed plate, which in turn has breakthroughs or perforations for fastening have at least the busbar support, but possibly also have perforations for further fastening of the intermediate holder to the sublimation itself.

Instead of a metal part that is welded to existing ribbed plates, a cranked intermediate bracket can also be used, which is fastened to an under-swelling with the same screw connection with which the ribbed plate is also held on the sleepers. The offset serves to bridge the thickness of the ribbed plate.

With such an inexpensive intermediate bracket, a support for busbar supports can be attached to track sleepers not provided for this purpose. Instead of openings in the intermediate bracket for commercially available screw connections for fastening to the threshold and / or the rail support, a stud bolt can also be welded onto the intermediate bracket or this can be provided with a recess for a hook screw.

Instead of welding or screwing on additional parts, the entire ribbed plate can also be exchanged for a special intermediate bracket which, from the start, comprises both the ribbed plate and the holding part as an integral component.

For concrete undulation with a W-shaped resilient rail fastening, a special intermediate bracket is proposed, which is either designed so that the angle guide plate used in such a rail fastening under-grips or again as Integral component is formed, which includes both an intermediate bracket for the busbar support and the angle guide plate. If necessary, the angle guide plate must be insulated with a plastic intermediate layer. Such an intermediate bracket can also be provided with an offset in order to compensate for differences in height of the surface of the concrete undulation and to be supported with the offset end on the sleeper surface. Alternatively, it is provided to equip the sleeper with a further dowel fastening in order to reach through the corresponding openings in the support and the intermediate bracket with a commercially available sleeper screw and to anchor them in the concrete sleeper. ,

For tracks with so-called Y-steel sleepers, it is advisable to weld a plate as an intermediate bracket directly onto the sleeper heads of the two parallel H-shaped steel beams that form a rail base. A position on the top chords as well as the bottom chords of the steel sleeper can be used for this.

Although the intermediate bracket is preferably made of steel, particularly in cases where it is to be welded to the threshold or the ribbed plates, it is also possible to use other materials such as plastic or wood or light metal without leaving the scope of the invention .

A particularly suitable busbar support which can be connected to such a holder consists of a C-shaped curved profile, the base of which has openings or hooks for connecting the busbar support to the Has intermediate bracket on the swell and whose cross-section tapers towards the end of the profile extending away from the base. At this tapered end, the busbar support itself is connected to the busbar support. While the busbar support is essentially subjected to a bending load in the area of its attachment to the intermediate bracket or the threshold, the load changes into one due to the weight to be borne for the busbar support and the busbar and any tapping forces acting on the busbar in the area of the tapered end Shear stress on the fasteners on the profile. For this reason, it is not necessary to manufacture the busbar support with a constant cross section. Material can also be saved.

The profile for the rail support consists of an H-shaped cross section with upper and lower chord and intermediate webs between the upper and lower chord. To improve the elastic properties and the stability of the profile, further webs can be arranged, for example, in the form of a truss or a meandering course between the upper and lower flange of the profile. Ideally, the profile sections in the upper and lower chord and on the webs are approximately the same thickness. This simplifies the manufacture of the injection mold and the injection of the material itself.

Because of the high insulation value of the bracket and the busbar support, they can be used universally for wood, concrete and steel sleepers.

The holder according to the invention or the partial profiles of the Holders and the busbar support are advantageously produced by injection molding in appropriate injection molds. The selected plastic raw material, preferably a granulate made of recycled plastic, is added in the desired amount of glass fiber and / or carbon black up to 2% by volume, but preferably

0.5 - 1.2 vol% admixed and added to the mold under high pressure. After the profile has been removed from the die, the still warm injection molded part is stored in warm water until it has absorbed about 0.5-3% by volume, preferably 1-2.5% by volume, of water. This measure leads to significant

Improvement of the impact strength of the plastic part, while the glass fibers serve for mechanical strengthening and the soot for UV stabilization of the plastic part.

For the sake of saving material and. To optimize all component properties, the holder is largely manufactured as a rotationally symmetrical hollow component. This saves material and simplifies the manufacture of the injection mold.

The clamping profiles for the base of the conductor rail, which belong to the complete holder, can also be produced by extrusion instead of in an injection mold. The choice of the appropriate process depends on the number of required clamping profiles and on the machine equipment of the respective manufacturer.

The invention will be explained in more detail with the aid of schematic diagrams. Show it

A base plate 8 made of plastic is fastened to the wooden sleeper 9 by means of a sleeper screw 10 (FIG. 1). The holding body 6 of the holder 1 sits in a fitting bore 19 and is additionally supported on the base plate 8 by a collar 11. The holding body 6 carries on its top the foot 4 of a ^" busbar 3, the tapping side of which is not shown. The rail foot 4 rests on the cover part 18 of the holding body 6. The cover part 18 is larger than the holding body 6 and has a rim 16 on the side. After inserting the busbar 3, the clamping profiles 2 are pushed over the lateral shelves 16, which run parallel to the rail foot, the wrap-around strips 15 and 14 guaranteeing the form-fitting hold of the clamping profiles 2 on the molded-on rim 16 of the holding body 6, while on the other hand the nose 13 ensures a secure fit of the rail base 4 on the clamping profile 2. So that the rail base 4 lies well on the cover part 18, it has a recess 17.

The middle part of the holding body 6 is cylindrical and has circumferential ribs 5. These molded ribs serve to stiffen the holding body, but primarily also to prevent current flow across the surface of the holding body 6 towards the threshold 9.

FIG. 2 shows a busbar support 20 as an integral version, in which the cylindrical holding part 21, analogous to the holder 20 in FIG. 1, is formed in one piece with the fastening foot 22. One of the clamping profiles is also replaced by the integral nose 23 which engages around the foot 4 of the busbar 3 on one side. On the opposite side, the retaining flange 26 is encompassed by a modified clamping profile 24, which additionally clamps the rail base 4. If necessary, a securing element can be inserted into a recess 25 which extends through the retaining flange 26 and the clamping profile 24. Analogously to FIG. 1, the busbar support 20 is fastened to the threshold 9 by means of threshold screw 10. To adjust the height, 22 compensation plates can be placed between the threshold 9 and the mounting foot. ι

FIG. 3 shows another holder 30 which is flanged by means of screw bolts 42 in front of the holding bracket 41 designed as a U-profile. At the attachment point of the holder 30 on the U-profile, this is equipped with a reinforcement 47. Both this reinforcement and the U-profile have slots 43, 44 for a vertical displacement of the screw bolt 42. This shift is used to adjust the height of the holder and can be done by a spindle 40. The cover 45 prevents contamination and serves as an abutment for the spindle. In the form shown, the holder 30 has not yet been pulled firmly against the U-profile 41. The rotationally symmetrical housing 27 with an integrated, cast steel nut 28 for the bolt 42 extends beyond the end of the holding body 39. After tightening the screw 42, the housing 27 enters the slot 44 and is guided laterally there, while the end face 40 of the holding body 39 comes to rest against the U-profile 41 and thus receives good support on the U-profile 41. Analogously to the holding body 6 according to FIG. 1, the rotationally symmetrical holding body 39 likewise has ribs 29 which serve the same purpose, namely to restrict the flow of current. The holder 30 is provided for a hanging arrangement of a busbar 3. An integral part of the

Holding body 39 are the hollow profile-like abutment 31 for the rail foot 4 of the busbar 3 and the rib 38 which surrounds the rail foot 4 on one side. After positioning the busbar 3 in the position shown, a clamping profile 34 is pushed over the outer rib 36 of the abutment 31, the flanges 35 and 37 clamping the rail foot 4 of the busbar 3, while on the other hand the flanges 33 and 35 of the clamping profile 34 on the clamping profile Secure abutment 31. Analogously to the embodiment in FIG. 1, the abutment 31 also has a recess 32 so that the rail foot 4 lies securely on the abutment 31.

4 shows a support 41 according to the invention of a busbar support with a width of approximately 500 mm and a height of approximately 300 mm. The support itself consists of a ribbed profile, with the top flange 52, the bottom flange 53, a vertical ribbing 68 and a diagonal ribbing 69, 70 which extends in a meandering or truss-like manner between the top flange and the bottom flange. To ^r of the base 54, the support 41 is anchored with a special intermediate frame on a standardized rail sleepers, as shown in Figs. 6 to 10 is shown. From the base, the profile extends to its tapered end 72, which is designed to accommodate a special attachment 42 for mounting a track holder. The cover 45 of the profile serves as an abutment for adjusting the attachment 46.

Fig. 5 shows the cross section according to section A-A in Fig. 4 of such a profile. The plastic profile made of polyamide as an integrally injection-molded component has a base 54 with the perforations 57, -; 64 and consists of the upper flange 52, the lower flange 53 and the intermediate webs 68 as well as the obliquely extending further webs 69, arranged orthogonally to the intermediate webs 68, 71. As can be seen in FIG. 5, the wall thickness of the profile is essentially of the same size, as a result of which the tool costs are kept within limits and optimum spraying of the polyamide material is possible. Fig. 5 shows the profile dimensions approximately in the original size and correct size / wall thickness ratio. It can be seen that such a shape offers a very high moment of resistance to the bending and shear forces that occur.

On a wooden swelling 50 of a track, the middle length M of which is indicated, are rails S with a K superstructure, consisting of the ribbed plate 61, which are fastened by sleeper screws 62, and the

Rail fastening 63 fixed on the threshold (Fig. 6). A special intermediate bracket 55 has been welded to the rib plate 61 with a weld seam 60, since the threshold 50 is not long enough to be able to fasten the base 54 of the support 41 directly to the threshold. Through a perforation 65 or 66 in the intermediate bracket 55 and a corresponding perforation 57 or 64 in the base 54 of the support 41, it is possible with the help usual threshold screws 59 to anchor the support 41 directly in the threshold and, on the other hand, to additionally fasten the base 54 of the support 41 by means of commercially available screws 58. From the support 41, only the upper flange 52 and the lower flange 53 and a special reinforcement 56 for the perforation 66 can be seen.

7 shows an alternative embodiment 67 of the intermediate bracket for the same superstructure, which in this case is also fixed on the threshold by the threshold screw 62 holding the rib plate 61.

Fig. 8 shows a plan view of the base of the support 41 with the holes 64 for the passage of a sleeper screw 59 through both the base 54 and the intermediate bracket as part 67 in the threshold 50. An elongated hole 57 with reinforcement 56 serves the FIG Passing through a fastening screw. The openings 64 and 57 through the base 54 of the support 41 are shown here as elongated holes to allow adjustment of the support relative to the rail, even if the holes in the threshold or in the holding part are not exact.

Fig. 9 shows a concrete undulation 49 on which a rail

S using a W-shaped spring 75, an angle guide plate 76 and a sleeper screw 74 in one

Dowel 73 of the sublimation 49 is anchored. An insulating plate 77 is inserted between a special holding part 78 and the angle guide plate 76. The holding part 78 is held on the one hand by the undergrip under the angle guide plate 76 and can also be held by a commercially available threshold screw 79, for example, which holds the holding part and the

Base 54 of the support 41 can reach through on the threshold be attached. In order to compensate for the surface shape of the sublimation 49, the holding part has an offset which is supported on the surface of the concrete sublimation 49.

10 shows a Y-shaped steel sleeper with three rail support points, which is formed from two parallel H-shaped steel girders. Here, an intermediate bracket 81 can be welded, glued or screwed to the upper chords of the Y-shaped steel sleeper 48 on the sleeper head; alternatively, it is possible to insert a holding part according to position 82 between the upper and lower chords of the H-shaped steel girders and weld them there. 11 to 13 show, with screw connections 88, rib plates 87 held on the sub-threshold for a k superstructure. A directly attached intermediate bracket 98, on which a base 85 of a busbar support 84 is held in a diagonal position by ribs 89 and further ribs for hook screw connections 86, is shown in FIG. 11. A similar diagonal fixation with hook screws 92 on the

Intermediate bracket 99 for the base 91 of a busbar support 90 is shown in FIG. 12. This type of fastening saves space on the intermediate bracket and at the same time counteracts the torsional forces acting on the busbar supports which result from the operating load.

FIG. 13 shows a busbar support 93 reinforced with the support with the legs 94 on the base 80, which is held on the intermediate holder 97 by a hook screw connection 95 seated in slot 96. All intermediate brackets or supports - even if not mentioned - can be equipped with elongated holes for lateral adjustment of the busbar supports.
