Description

Zunσenkasten für RillenschienenweichenZunσenkasten for grooved rail switches
Die Erfindung bezieht sich auf einen Zungenkasten für Rillenschienenweichen mit einer Backenschiene, einer Gleitplatte und einer Beischiene, wobei die Beischiene und die Gleitplatte und eine Grundplatte miteinander verschweißt sind und mit der Backenschiene ein kastenförmiges Profil ausbilden.The invention relates to a tongue box for grooved rail switches with a stock rail, a sliding plate and a side rail, the side rail and the sliding plate and a base plate being welded together and forming a box-shaped profile with the back rail.
Ein Zungenkasten der eingangs genannten Art ist beispielsweise der DE 39 04 026 C2 zu entnehmen. Bei dieser bekannten Konstruktion sind die Backenschiene, die Gleiplatte, die Beischiene und die Grundplatte miteinander verschweißt, sodaß eine stabile Kastenkonstruktion erzielt wird. Um eine derartige Verschweißung jedoch durchzuführen, ist es naturgemäß erforderlich ent- sprechend schweißbare Stähle zu verwenden, sodaß hochverschleißfeste Stähle als Material für die Backenschiene nicht in Betracht kommen, wenn nicht eine aufwendige Wärmebehandlung in Kauf genommen werden muß.A tongue box of the type mentioned in the introduction can be found, for example, in DE 39 04 026 C2. In this known construction, the stock rail, the slide plate, the side rail and the base plate are welded together, so that a stable box construction is achieved. In order to carry out such a welding, however, it is naturally necessary to use correspondingly weldable steels, so that highly wear-resistant steels cannot be considered as material for the stock rail unless a costly heat treatment has to be accepted.
Das Problem der mangelnden Schweißbarkeit entsprechend verschleißfester Stähle wurde bereits in der DE 33 43 239 Cl erkannt . Gemäß dieser älteren Zungenvorrichtung wurde ein Kastenprofil mit der Backenschiene verschraubt, wobei dies damit begründet wurde, daß Backenschienen mit dem erforderlichen spe- ziellen Walzprofil üblicherweise einen durchschnittlichen Kohlenstoffgehalt von 0,6 Gew.% aufweisen, sodaß eine Verschweißung nur nach ausreichender Vorwärmung durchgeführt werden kann. Selbst bei einer derartigen Vorwärmung und auch bei sorgfältig durchgeführter Schweißung besteht aber immer noch die Ge- fahr des Anrisses im Bereich der Backenschiene jeweils an den Enden der Grundplatten, weil in diesem Bereich die Schweißnaht eine Kerbwirkung ausübt. Um der Gefahr der Bildung weiterer Anrisse beim unvermeidlichen Richten des Zungenbereiches nach der Schweißung zu begegnen, wurde hier eine verschraubte Konstruk- tion gewählt. _ _The problem of the lack of weldability in accordance with wear-resistant steels was already recognized in DE 33 43 239 Cl. According to this older tongue device, a box profile was screwed to the stock rail, the reason being that stock rails with the required special rolled profile usually have an average carbon content of 0.6% by weight, so that welding can only be carried out after sufficient preheating . Even with such a preheating and also with a carefully carried out welding there is still the risk of tearing in the area of the stock rail at the ends of the base plates, because in this area the weld seam has a notch effect. In order to counter the risk of further cracks forming when the tongue area is inevitably straightened after welding, a screwed construction was selected here. _ _
Die Erfindung zielt nun darauf ab, die Vorteile einer verschweißten Konstruktion in Bezug auf die Stabilität zu nützen und es trotzdem zu ermöglichen hochverschleißfeste Backenschienen einzusetzen ohne daß auf die Stabilität einer Schweißkon- struktion verzichtet werden muß. Zu Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß die Backenschiene durch mit dem kastenförmigen Profil und/oder der Grundplatte verschweißte Spannstücke kraft- und formschlüssig mit dem kastenförmigen Profil verbunden ist. Dadurch, daß Spannstücke eingesetzt werden, welche in einer sogenannten Schrumpfverschweißung jeweils mit Bauteilen aus gutschweißbaren Materialien verschweißt werden können, wird eine kraft- und formschlüssige Verbindung gewährleistet, bei welcher die Gefahr einer Lockerung von Schrauben oder anderen lösbaren Bauteilen vermieden wird und alle Vorteile einer verschweißten Konstruktion inbezug auf die Stabiliät des Zungenkastens erzielt werden können.The invention now aims to utilize the advantages of a welded construction in terms of stability and still make it possible to use highly wear-resistant stock rails without having to forego the stability of a welded construction. To achieve this object, the design according to the invention essentially consists in the fact that the stock rail is non-positively and positively connected to the box-shaped profile by means of clamping pieces welded to the box-shaped profile and / or the base plate. The fact that clamping pieces are used, which can be welded in a so-called shrink welding with components made of easily weldable materials, ensures a non-positive and positive connection, in which the risk of loosening screws or other detachable components is avoided and all the advantages of a welded Construction in relation to the stability of the tongue box can be achieved.
Mit Vorteil ist die erfindungsgemäße Ausbildung hierbei so ge- troffen, daß das Spannstück als Bundbuchse ausgebildet ist, welche durch eine Durchbrechung des Schienenstegs der Backenschiene gesteckt ist und mit dem kastenförmigen Profil durch Schrumpfschweißung verbunden ist, und daß der Bund der Bundbuchse die Durchbrechung des Steges der Backenschiene an der dem kastenförmigen Profil abgewandten Außenseite übergreift. Eine derartige Bundbuchse welche in eine entsprechende Ausnehmung bzw. Durchbrechung des Schienensteges hindurchgesteckt wird, erlaubt es nach einem Schrumpfschweißen nicht nur die entsprechende kraftschlüssige Verbindung durch Anpressen des Bundes der Bundbuchse, sondern auch die formschlüssige Verbindung durch Einstecken in die Durchbrechung des Schienensteges zu gewährleisten, wobei die unmittelbare Verschweißung zwischen dem schlecht schweißbaren Material der hochverschleißfesten Backenschienen und den Bauteilen des Kastenprofiles vermieden wird. Die Schweißverbindung kann daher in konventioneller Weise ohne aufwendige Wärmebehandlung durchgeführt werden, wobei die erforderliche Stabilität gewährleistet ist. In besonders einfacher Weise kann die Ausbildung dadurch noch weiter versteift werden, daß der Schienenfuß der Backenschiene durch mit der Grundplatte verschweißte plattenförmige Spannstücke übergriffen ist. Derartige plattenförmige Spannstücke können gleichfalls auf Grund des mit der Verschweißung der Platten verbundenen Schrumpfprozesses eine zusätzliche kraftschlüssige Verbindung bewirken, so daß die Stabilität der Konstruktion weiter erhöht wird.The design according to the invention is advantageously made in such a way that the clamping piece is designed as a collar bushing which is inserted through an opening in the rail web of the stock rail and is connected to the box-shaped profile by shrink welding, and that the collar of the collar bushing is the opening in the web overlaps the stock rail on the outside facing away from the box-shaped profile. Such a collar bushing which is inserted into a corresponding recess or opening in the rail web, after shrink welding, not only allows the corresponding positive connection by pressing the collar of the collar bushing, but also to ensure the positive connection by plugging into the opening in the rail web, whereby the direct welding between the poorly weldable material of the highly wear-resistant stock rails and the components of the box profile is avoided. The welded joint can therefore be carried out in a conventional manner without expensive heat treatment, the required stability being guaranteed. In a particularly simple way The design can be further stiffened in that the rail foot of the stock rail is overlapped by plate-shaped clamping pieces welded to the base plate. Such plate-shaped clamping pieces can also cause an additional non-positive connection due to the shrinking process associated with the welding of the plates, so that the stability of the construction is further increased.
Mit Vorteil lassen sich hochverschleißfeste Werkstoffe als Material für die Backenschienen verwenden, wobei vorzugsweise die Ausbildung so getroffen ist, daß die Backenschiene als kopf- gehärtete Rillenschiene aus Stahl mit einem C-Gehalt von 0,6 - 0,9 Gew.%, insbesondere 0,8 Gew.%, und Festigkeiten des Grundkörpers von 850 - 1050 N/mm2 und Kopffestigkeit von 1100 - 1200 N/mm2 ausgebildet sind und insbesondere daß ein naturharter Stahl vom Typ R 800 oder Typ R 900 A oder vergütete Stähle der Type HSHM oder HSH für die Backenschienen eingesetzt ist. Derartige Stähle, welche einen Kohlenstoffgehalt von etwa 0,8 Gew.% aufweisen, sind nur bedingt oder gar nicht schweißbar und können nur durch spezielle Schweißverfahren bzw. durch eine dem Schweißen vorangehende Vorwärmung, beispielsweise in einem Gasofen auf etwa 500 Grad Celsius, schweißtauglich gemacht werden oder scheiden für diese Anwendung aus . Durch die Verwendung von Spannstücken kann eine derartige Vorwärmung entfallen bzw. eine Anwendung sichergestellt werden. Da bei der erfindungsgemäßen Schrumpfverschweißung auch keine Längsnähte, wie sie durch Verschweißen der Schiene an der Grundplatte auftreten würden, gebildet werden, ist eine Nachbearbeitung durch Ausrichten nicht oder nur in geringem Umfang erforderlich.Highly wear-resistant materials can advantageously be used as material for the stock rails, the design preferably being such that the stock rail is a head-hardened grooved rail made of steel with a C content of 0.6-0.9% by weight, in particular 0 , 8% by weight, and strengths of the base body of 850-1050 N / mm 2 and head strength of 1100-1200 N / mm 2 are formed, and in particular that a naturally hard steel of the type R 800 or type R 900 A or tempered steels of the type HSHM or HSH is used for the stock rails. Such steels, which have a carbon content of about 0.8% by weight, can only be welded to a limited extent or not at all and can only be made weldable by special welding processes or by preheating the welding, for example in a gas furnace to about 500 degrees Celsius are or are excluded from this application. Such preheating can be dispensed with or use can be ensured by using clamping pieces. Since no longitudinal seams, as would occur by welding the rail to the base plate, are formed in the shrink welding according to the invention, post-processing by alignment is not necessary or only to a small extent.
Mit Vorteil wird die gute Schweißbarkeit des Kastenprofiles und der mit dem Kastenprofil zu verschweißenden Spannstücke dadurch gewährleistet, daß die Beischiene und die Bauteile des miteinander verschweißten kastenförmigen Profils aus gut schweiß- barem Baustahl, insbesondere der Qualität ST50, gefertigt sind. Das kastenförmige Profil kann unter Verwendung von Stützplatten vor der Festlegung der Backenschienen durch Schrumpfschweißung der Bundbuchse bereits vollständig ausgebildet sein, wofür mit Vorteil die Ausbildung so getroffen ist, daß das miteinander verschweißte kastenförmige Profil aus im Querschnitt zueinander parallelen Stützplatten und der mit den Stützplatten verschweißten Gleitplatte sowie der zur Gleitplatte parallelen Grundplatte besteht, wobei die Beischiene mit einer der beiden Stützplatten verschweißt ist. Die Festlegung der Backenschienen erfolgt hierbei in einfacher Weise dadurch, daß die Bundbuchse mit der der Beischiene gegenüberliegenden Stützplatte verbunden ist, wobei, um eine entsprechende SchrumpfWirkung und damit eine entsprechende kraftschlüssige Verbindung zu gewährleisten, mit Vorteil die Ausbildung so getroffen ist, daß die axiale Länge der auf Anschlag des Bundes am Steg der Backenschiene eingeschobenen Bundbuchse geringer ist als die Breite des Steges der Backenschiene, und daß der Ringspalt zwischen der Bundbuchse und der Stützplatte durch Schrumpfschweißen geschlossen ist. Nach dem Erstarren der in den Ringspalt in Form eines Lochver- Schweißens eingebrachten Schweißnaht erfolgt durch thermische Kontraktion eine entsprechende Spannwirkung, welche die hohe Stabilität und Festigkeit gewährleistet.The good weldability of the box profile and the clamping pieces to be welded to the box profile is advantageously ensured by the fact that the side rail and the components of the box-shaped profile welded together are made of easily weldable structural steel, in particular of the ST50 quality. The box-shaped profile can already be completely formed using support plates before the fixing of the stock rails by shrink welding the flange bush, for which the design is advantageously made such that the box-shaped profile which is welded to one another consists of cross-sections of parallel support plates and the slide plate welded to the support plates as well as the base plate parallel to the slide plate, the side rail being welded to one of the two support plates. The fixing of the stock rails takes place in a simple manner in that the flange bushing is connected to the support plate opposite the side rail, whereby, in order to ensure a corresponding shrinkage effect and thus a corresponding positive connection, the design is advantageously made such that the axial length the collar bush pushed into the web of the stock rail at the stop of the federal government is less than the width of the web of the stock rail, and that the annular gap between the collar bush and the support plate is closed by shrink welding. After the solidification of the weld seam in the annular gap in the form of a hole welding, a corresponding tensioning effect takes place by thermal contraction, which ensures the high stability and strength.
Eine zusätzliche Erhöhung der Stabilität läßt sich noch dadurch erzielen, daß mit der Grundplatte Stützteile für die seitliche Abstützung der Backenschiene verschweißt sind.An additional increase in stability can be achieved in that support parts for the lateral support of the stock rail are welded to the base plate.

Lateral supports 8 are also welded to the base plate 4, which, with the support members 9, provide lateral support for the grooved rail 2. The rail web of the grooved rail 2 is designated 10 here.
Aus der Darstellung nach Figur 3 ist nun die Kastenkonstruktion näher ersichtlich.

Die Bundbuchse 14 wird über eine Lochschweißung, deren Schweißnaht mit 15 bezeichnet ist, mit einem der plattenförmigen Stützteile 12 verschweißt, wobei hier eine Schrumpfverschweißung vorgenommen wird, welche dazu führt, daß nach dem Erstarren der Schweißnaht der Bund 16 der Bundbuchse 14, welcher die Durchbrechung 13 des Schienensteges außen umgreift, kraftschlüssig gegen den Schienesteg gepreßt wird und somit den Schienensteg kraft- und formschlüssig mit dem Kastenprofil verbindet.The box construction can now be seen in more detail from the illustration according to FIG. The box-shaped profile consists of the base plate 4, the slide plate 5, in which the tongue of the rail switch is slidably guided, and two vertically extending support plates 11 and 12.
