Description

Anordning for oppvarmning av jernbanesporveksler. Device for heating railway switches.

Denne oppfinnelse vedrører en anordning for oppvarming av jernbanesporveksler, hvor elektriske varmeelementer er anbragt langs hver jernbaneskinne, fortrinnsvis på oversiden av skinnefoten, og ved deres ene ende er koblet til en koblingsboks. This invention relates to a device for heating railway switches, where electric heating elements are placed along each railway rail, preferably on the upper side of the rail foot, and at one end of which are connected to a junction box.

Formålet med oppfinnelsen har vært å frembringe en slik anordning som er mindre utsatt for driftsforstyrrelser på grunn av vibrasjoner i skinnene og svillene ved jernbanetogenes passering enn tidlig-ere foreslåtte liknende anordninger, og som har dens deler liggende slik at de ikke er utsatt for lett å skades ved ytre påvirk-ning. The purpose of the invention has been to produce such a device which is less susceptible to operational disturbances due to vibrations in the rails and sleepers during the passage of railway trains than earlier proposed similar devices, and which has its parts lying down so that they are not exposed to easy is damaged by external influences.

Det som i første rekke kjennetegner That which primarily characterizes

oppfinnelsen er at koblingsboksen er anbragt mellom jernbanesporets to skinner og uavhengig av skinnen understøttet på eller mellom jernbanesporoverbygningens sviller, at varmeelementene dannes av en-keltleder- rørelementer som er plasert to ved siden av hverandre langs skinnene og har inntil hverandre, ved den ene av sine ender, og midt foran koblingsboksen liggende endedeler ombøyet vinkelrett bort fra skinnen i retning mot koblingsboksen og fast tilsluttet denne, mens rørelement-ene ved de ender som ligger lengst borte fra koblingsboksen er fastholdt til skinnen med festeklemmer som tillater rør-elementene å underkastes begrensete stillings- og formendringer uavhengig av hverandre og av skinnen. the invention is that the junction box is placed between the two rails of the railway track and independently of the rail supported on or between the sleepers of the railway track superstructure, that the heating elements are formed by single-cell conductor pipe elements which are placed two next to each other along the rails and have adjacent to each other, at one of their ends, and end parts lying in the middle of the junction box bent perpendicularly away from the rail in the direction of the junction box and firmly connected to it, while the pipe elements at the ends furthest away from the junction box are secured to the rail with fixing clamps which allow the pipe elements to be subjected to limited positions - and shape changes independently of each other and of the rail.

I det etterfølgende vil det bli beskre-vet en utførelsesform for anordningen iføl-ge oppfinnelsen for å klargjøre denne, idet In what follows, an embodiment of the device according to the invention will be described in order to clarify this, since

det henvises til de medfølgende tegninger, hvor: reference is made to the accompanying drawings, where:

Fig. 1 viser i horisontalprojeksjon et utsnitt av en jernbaneskinne samt sviller utstyrt med anordningen ifølge oppfinnelsen. Fig. 2 viser et bruddstykke av denne anordning, sett i projeksjon i svillens lengderetning fra linjen A—A i fig. 1. Fig. 3 viser deler av anordningen ifølge fig. 1 sett i vertikalprojeksjon vinkelrett mot skinnens lengderetning fra linjen B— B i fig. 1. Fig. 4 viser et tverrsnitt etter linjen Fig. 1 shows in horizontal projection a section of a railway rail and sleepers equipped with the device according to the invention. Fig. 2 shows a broken piece of this device, seen in projection in the sleeper's longitudinal direction from the line A—A in fig. 1. Fig. 3 shows parts of the device according to fig. 1 seen in a vertical projection perpendicular to the longitudinal direction of the rail from the line B— B in fig. 1. Fig. 4 shows a cross-section along the line

C—C i fig. 1. C—C in fig. 1.

Fig. 5 viser et liknende tverrsnitt men Fig. 5 shows a similar cross-section but

viser en modifisert utførelse. shows a modified embodiment.

Ved anordningen ifølge oppfinnelsen dannes de elektriske varmeelementer, som tjener til å oppvarme en jembanesporvek-sel, av rørelementer av den art som inne-holder en enkel oppvarmingsleder (det vil i alminnelighet si en eneste spiral av mot-standstråd innpakket i isolasjonsmateriale inne i et mantelrør). Disse rørelementer er anordnet i to par, idet elementene i hvert par, som er betegnet med 1 og 2, forløper ved siden av hverandre fra en koblingsboks 11, som ligger omtrent ved midten av spor-ækselen, langs skinnen 4 nesten frem til vekseltungens spiss for det ene par og i motsatt retning, det vil si mot vekseltungens rot, for det andre par. Rørelementene 1 og 2 i hvert par har deres ledere forbun-iet med hverandre ved den ende som lig-aer lengst fra boksen 11, så at oppvarm-.ngsstrømmen passerer i en slynge fra boksen 11 gjennom begge elementer. De holdes fastspent ved skinnefoten ved hjelp av festeklemmer slik det beskrives nærmere lengere frem. In the device according to the invention, the electric heating elements, which serve to heat a single-phase transformer, are formed by pipe elements of the kind that contain a simple heating conductor (that is, in general, a single spiral of resistance wire wrapped in insulating material inside a casing pipe). These pipe elements are arranged in two pairs, the elements in each pair, which are denoted by 1 and 2, extend next to each other from a junction box 11, which is located approximately in the middle of the track shaft, along the rail 4 almost to the tip of the changer tongue for one pair and in the opposite direction, i.e. towards the root of the alternate tongue, for the other pair. The pipe elements 1 and 2 in each pair have their conductors connected to each other at the end which lies farthest from the box 11, so that the heating current passes in a loop from the box 11 through both elements. They are held tight at the rail foot using fastening clamps as described in more detail further on.

Ved den anordning som er vist i figur- In the case of the device shown in fig.

ene 1 til 3 er koblingsboksen 11 anbragt helt innenfor skinnen på to holdere 12 1 to 3, the junction box 11 is placed completely inside the rail on two holders 12

(bare den ene er synlig på tegningene), (only one is visible in the drawings),

som er anbragt tversover og fastskrudd til to sviller 13. Disse holdere har i sidepro-jeksjon den form som vises i fig. 3 og bærer boksen 11 i den forsenkning som finnes mellom svillene 13. Boksen 11 er på den side som vender mot skinnen utstyrt med en tilkoblingsflens 14 med to hull, og de endedeler av de to parene av rørelementer I og 2 som ligger nærmest koblingsboksen which are arranged transversely and screwed to two sleepers 13. These holders have the shape shown in fig. in side projection. 3 and carries the box 11 in the recess found between the sleepers 13. The box 11 is on the side facing the rail equipped with a connecting flange 14 with two holes, and the end parts of the two pairs of pipe elements I and 2 which are closest to the connection box

II er ombøyet vinkelrett mot skinnen og strekker seg frem til boksen 11 hvor de er innført i de nevnte hull i flensen 14, hvori hvert par rørelementer fastholdes av en felles nippel 15, som er innskrudd i et av hullene. II is bent perpendicular to the rail and extends to the box 11 where they are inserted into the aforementioned holes in the flange 14, in which each pair of pipe elements is retained by a common nipple 15, which is screwed into one of the holes.

Rørelementene 1 but is arranged fixed in relation to the sleepers 13, it will follow the latter's vibrations, which are weaker than those of the rail due to the damping to which they are subjected during the transition from the rail to the sleepers and during propagation through these latter. The pipe elements 1

og 2 vil derfor bli utsatt for visse formendringer og stillingsendringer, som de dog uten ulempe tillater, takket være at de er litt bevegelige uvhengig av hverandre og av skinnene som de er festet på. Særlig kan rørelementene om dette kreves, under- and 2 will therefore be exposed to certain changes in shape and position, which they allow without inconvenience, thanks to the fact that they are slightly movable independently of each other and of the rails on which they are fixed. In particular, the pipe elements can, if this is required, sub-

De kabler hvorigjennom koblingsboksen 11 er tilkoblet til et strømuttak, for eksempel på a certain torsion is thrown, distributed over the entire length that runs along the rail. The cables through which the junction box 11 is connected to a power outlet, for example on

De festeklemmer hvormed rørelement- The fastening clamps with which the pipe element

foten, vises i to utførelser i fig. 4 og 5. I the foot, is shown in two versions in fig. 4 and 5. I

begge figurer består festeklemmen av et gjenget skaft 16 med en på dets ene ende påsveiset U-profil-del 17 (se også fig. 1), in both figures, the fastening clamp consists of a threaded shaft 16 with a U-profile part 17 welded on at one end (see also fig. 1),

spennes an om den sistnevnte kanten på skinnefoten med muttere 19. Mellom U-profildelen 17 og kanten på skinnefoten er det innsatt et V-formet bøyet fjærende platestykke 20, hvis øvre ben danner en plateklemme 21 som strekker seg inn over skinnefoten forbi delen 17 som et overfall som de to rørelementer 1 og 2 fastholdes under. I fig. 4 ligger rørelementene direkte an mot skinnefoten og oppvarmer der-igjennom denne og hele skinnen ved led-ningsvarme. Ved utførelsesformen i fig. 5 is clamped to the latter edge of the rail foot with nuts 19. Between the U-profile part 17 and the edge of the rail foot, a V-shaped bent springy plate piece 20 is inserted, the upper leg of which forms a plate clamp 21 which extends over the rail foot past the part 17 which an overhang under which the two pipe elements 1 and 2 are held. In fig. 4, the pipe elements lie directly against the rail foot and thereby heat this and the entire rail by conduction heating. In the embodiment in fig. 5
