Description

Zum Anziehen und Lösen von Schwellenschrauben des Eisenbahnoberbaues werden Kreuzschlüssel benutzt. Da die Holzschrauben meist fest in der Holzschwelle sitzen, ist es notwendig, daß mehrere Arbeiter zum Lösen einer Schraube tätig sein müssen. Weil erhebliche Drehmomente einzuleiten sind, nutzen sich die Schlüssel schnell ab. Die Abnutzung des Schlüsselkopfes ist so stark, daß die Längsflanken des Schlüssels an diagonal gegenüberliegenden Stellen ausgebuchtet werden. Dieser Verschleiß tritt besonders bei den Schlüsselköpfen auf, die an motorbetriebenen Ein- bzw. Ausschraubgeräten sitzen. Man hat daher die Backen oder Teile der Backen auswechselbar so gestaltet, daß sie Teile von Zy lindermantelflächen mit Kreis-, Ellipsen- oder ähnlichen Querschnittsformen bilden. Diese Backen übergreifen mit Spiel die Außenflächen der zu lösenden Schraubenköpfe und kommen nur zum Teil zur Anlage.For tightening and loosening sleeper screws on the railway superstructure cross keys are used. Because the wood screws are usually firmly in the wooden sleeper sit, it is necessary that several workers are employed to loosen a screw have to. Because considerable torques have to be introduced, the keys are used off quickly. The wear of the key head is so strong that the longitudinal flanks of the key can be bulged out at diagonally opposite positions. This Wear occurs especially on the key heads that are on motorized Screwing or unscrewing devices. You therefore have the jaws or parts of the jaws interchangeable designed so that they parts of Zy cylinder jacket surfaces with circular, Form elliptical or similar cross-sectional shapes. These jaws overlap with Play the outer surfaces of the screw heads to be loosened and only partially come to the System.

Es ist Aufgabe der Erfindung, kleine Backenteile einzusetzen, um an Austauschmaterial zu sparen. Erfindungsgemäß wird dies dadurch erreicht, daß die auswechselbaren Backen aus stabähnlichen, die Schraubenachse senkrecht kreuzenden Einsätzen bestehen und vorzugsweise an den Längsseiten der Schlüsselkopfanlageflächen angeordnet sind. Der Schlüsselkopf enthält in seiner Längsachse senkrecht kreuzende Schlitze, deren Breite im wesentlichen der Backenbreite entspricht. Zweckmäßigerweise werden die Backen längs geriffelt, um ein Abrutschen der Schlüsselköpfe von den Schrauben bzw. Muttern zu verhindern.It is the object of the invention to use small jaw parts to To save replacement material. According to the invention this is achieved in that the exchangeable jaws made of rod-like, the screw axis perpendicularly crossing Inserts exist and preferably on the long sides of the key head contact surfaces are arranged. The key head contains vertically crossing points in its longitudinal axis Slots, the width of which corresponds essentially to the width of the jaws. Appropriately the jaws are grooved lengthways to prevent the key heads from slipping off the To prevent screws or nuts.

Man kann die eingeschobenen Backen so ausbilden:, daß sie in den Schlitzen des Schlüsselkopfes festsitzen, also beispielsweise nur durch Herausschlagen entfernt werden können. Da hierdurch die Schlitze beschädigt werden können, wird das Herausfallen der Backen durch einen über den Umfang des Schlüsselkopfes geschobenen Ring verhindert. Der Ring kann, wenn man die Backen auswechseln will, nach oben gedrückt werden. In den Zeichnungen ist ein Ausführungsbeispiel eines erfindungsgemäßen Schlüsselkopfes veranschaulicht. Es zeigt Fig. i eine Seitenansicht eines Schlüsselkopfes in teilweisem Schnitt, Fig. ? einen Schnitt in Richtung A-B der Fig. i, die eingesetzten Backen sind nicht sichtbar.One can train the inserted jaws so: that they are in the slots of the key head are stuck, for example only removed by knocking out can be. Since this can damage the slots, it will fall out the jaws are prevented by a ring pushed over the circumference of the key head. If you want to change the jaws, the ring can be pushed upwards. In the drawings is an embodiment of a key head according to the invention illustrated. It shows Fig. I a side view of a key head in part Section, fig. a section in the direction A-B of Fig. i, the inserted jaws are not visible.

An dem Ansatzstück i, das zum Einleiten des erforderlichen Drehmomentes dient, befindet sich der Schlüsselkopf a, der zwei die Längsachse des Schlüssels senkrecht kreuzende Schlitze 3 und aufweist, in die die Backen 5 und 6 eingeschoben werden. Diese Backen besitzen Riefen 7 an einer oder beiden Seiten. Ein Ring 8 verhindert das Herausfallen der Backen.At the end piece i, which is used to introduce the required torque serves, there is the key head a, the two of the longitudinal axis of the key perpendicularly intersecting slots 3 and, into which the jaws 5 and 6 are inserted will. These jaws have grooves 7 on one or both sides. A ring 8 prevents the jaws falling out.
