Description

Verfahren zum Verschweißen der im Eisenbahngleis vorhandenen Stoßlücken mittels aluminothermischen Zwischengusses Beim Eisenbahngleis ist der Schienenstoß rntweder mitten zwischen zwei Schwellen (schwebender Stoß) oder mitten auf einer Doppelschwelle (ruhender Stoß) gelagert. Seli@1-(#ißt inan die Schienen nach den be- kannten aluminothermischen Verfahren in üb- licher Weise zusammen, so tritt bisher immer eine @Terkürzung des Schienenstrange: wenig- -teils tim die Stoßlückenbreite ein. 1:s werden also hei fortlaufenden Schweißungen clie Stöße auf ihren Unterlagen in tinzulii,siger Weise verschoben, wenn nicht die ganze Bettung ent- sprechend unigebaut oder der Längenverlust stellenweise durch Einschaltung von he:on- deren Paßstücken ausgeglichen wird. Gegenstand der Erfindung ist ein '\"erfah- ren, die Stoßlücken der auf den Schwellen frei liegenden Schienen so zu ver:cli%vcißen, daß die Stoßlage in hezug auf die Scliwellenunter- lage gewahrt bleibt. Bei eingebettetem Stra- 13cnhaluiglcis wird (lies hekaillitlich mittels de., I-Zeilprel.iverfahrens erreicht, (las ini vor- li(;'lenden Fall nicht anwendbar i:t. Gemäß der Erfindung löst nian in b(-kannter Weise eine Schiene auf den Schwellen und rückt sie .o weit in Richtung ihrer Achse von der -'#,cli@veißstclle ab, wie die l)eiiaclil)arte Stoßlücke es zuläßt. Die Schweißlücke kann hierdurch durchschnittlich tun (las Doppelte einer gewöhnlichen Stoßlücke verrri113ert wer- den. Diese Breite ist für eineu altimino- therinischen Zwischenguß in Höhe des ganzen Schienenquerschnitts ausreichend. Uninittel- har nach dessen Elnguß wird die lose Schiene z. B. mittels eines Kleninlapparates, der an rletn @Cli\\'elßstoß angebracht ist, oder mittels eine: Scliienenrückers, der an der henach- harten Stoßlücke angesetzt ist, wieder in be- kannter Weise an die feste Scliielie heran- gepreßt. Es ist bekannt, die Schienen so weit zusammenzupressen, bis ihre Profilflächen sich berühren. Nach dein @-ertahren gemäß der lrtindung werden sie in lieuai-tiger nur so weit zusammengepreßt, bis an der benach- barten Stoßlücke die um (las ho kannte Schruinpfinaß der Schweißstelle verringerte frühere Stoßlückenhreite wieder erzielt ist. ach vollständiger :\hlcüliltuig der Schweiß- stelle hat diese benachbarte Stol31iicl;e dann wieder ihre ursprüngliche Breit(. Sie liegt wieder mitten über ihrer `tol3unterlage. Der zu#ammen geschweißte Schienenstrang hat keilten Längenverlust erlitten. Die liicke i.t in bekannter Güte durch eine koni- priniierte Legierung von aluminr@therini.chem Eisen und Schienen:ialil ausgefüllt. Das Gleis liefst spannungslos, wenn die Temperatur vor und nach der Schwe ißtlng wieder die -leiche ist. Process for welding the joint gaps in the railroad track by means of aluminothermic intermediate casting The rail joint is on the railroad track either in the middle between two thresholds (floating thrust) or in the middle of one Double sleeper (static joint) mounted. Seli @ 1 - (# eats the rails after the known aluminothermic processes in common together, it has always been the case up to now a @ shortening of the rail track: little- -part part of the joint gap width. 1: s will be so with continuous welds the joints on their records in tinzulii, siger manner shifted if the entire bedding is not Speaking unassembled or the loss of length in places by including he: on- whose fittings are compensated. The subject of the invention is a '\ "experienced ren, clear the joint gaps on the sleepers to cli% vcißen lying rails so that the impact position in relation to the location is preserved. With embedded street 13cnhaluiglcis is (read hekaillitlich means de., I-Zeilprel.iver procedure reached, (read ini a- li (; 'lenden case not applicable i: t. According to the invention, nian solves in b (-know Way a rail on the sleepers and moves it .o far in the direction of its axis from the - '#, cli @ veißstclle, like the l) eiiaclil) arte Gap allows it. The sweat gap can doing this on average (read doubles an ordinary joint gap the. This width is for a u altimino- Therin intermediate pour in the amount of the whole Rail cross-section sufficient.

It is known the rails so far to press together until their profile surfaces touch. After your @ -driving according to the You will only find out in lieuai-tiger pressed together until the adjacent barted joint gap that around (las ho knew Reduced shrinkage of the weld previous joint gap is achieved again. oh more complete: \ hlcüliltuig the sweat This neighboring stub has then back to its original width (.

The track ran without tension when the temperature was up and after the sweat again the same person is.
