Description

Die Erfindung betrifft eine Klemmzange zur kraftschlüssigen Verbindung mit einer Schiene für deren Bewegung in Schienenlängsrichtung.The invention relates to a clamp for non-positive connection a rail for its movement in the longitudinal direction of the rail.

Durch US 5 295 440 ist bereits eine Klemmzange zum Abziehen von Schienen bekannt. Diese Klemmzange ist im Querschnitt derart geformt, daß der Schienenkopf von Schienensteg zu Schienensteg umschlossen wird. Eine kraftschlüssige Verbindung zwischen Klemmzange und Schiene ist dadurch erzielbar, indem zwischen Schienenkopf und Klemmzange ein Keil eingetrieben wird. Eine derartige bekannte Klemmzange hat allerdings den Nachteil, daß mit dem Keil die Fahrfläche des Schienenkopfes beschädigt wird.Through US 5 295 440 is already a clamp for pulling rails known. This clamp is shaped in cross section such that the Rail head is enclosed from rail web to rail web. A This creates a non-positive connection between the clamp and rail can be achieved by driving a wedge between the rail head and the clamp becomes. However, such a known clamping pliers has the disadvantage that that the driving surface of the rail head is damaged with the wedge.

Eine weitere Klemmzange ist durch FR 2 488 577 bekannt, wobei verschwenkbar gelagerte Klemmbacken durch Hydraulikzylinder an den Schienensteg angepreßt werden. Eine derartige Klemmzange ist konstruktiv relativ aufwendig und erfordert außerdem die Zuführung von Energie.Another clamp is known from FR 2 488 577, but can be pivoted mounted jaws by hydraulic cylinders on the rail web be pressed. Such a clamp is structurally relative complex and also requires the supply of energy.

Gemäß FR 2 557 551 ist eine zum gleichzeitigen Erfassen von zwei Schienen ausgebildete Klemmzange bekannt, die allerdings nur zum Anheben der Schienen geeignet ist.According to FR 2 557 551 one is for simultaneous detection of two rails trained pliers known, but only for lifting the Rails is suitable.

Schließlich ist durch DE 94 08 678 U1 noch eine weitere Klemmzange zum temporären Verbinden zweier Schienenenden bekannt. Diese Klemmzange besteht aus zwei durch eine Schraubverbindung miteinander koppelbaren Klemmbacken, die jeweils zur Anlage an den Schienensteg vorgesehene, exzentrisch gelagerte Klemmräder aufweisen.Finally, DE 94 08 678 U1 is another clamp for Temporary connection of two rail ends known. This clamp consists of two that can be coupled together by a screw connection Clamping jaws, the one intended for bearing against the rail web, eccentric have mounted pinch wheels.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer gattungsgemäßen Klemmzange, die auch bei - bezüglich einer normal zur Schienenlängsrichtung verlaufenden Richtung - dicht aneinandergereihten Schienen ein problemloses Abziehen einer einzelnen Schiene ermöglicht. The object of the present invention is to create a generic Clamping pliers, which are also normal to the longitudinal direction of the rail running direction - closely lined up rails allows easy removal of a single rail.

Diese Aufgabe wird erfindungsgemäß mit einer gattungsgemäßen Klemmzange dadurch gelöst, daß zwei zur Aufnahme eines Schienenkopfes und eines Schienensteges der abzuziehenden Schiene voneinander distanzierte Klemmbacken vorgesehen sind, die durch eine Backenhalterung miteinander verbunden sind und am von der Backenhalterung weiter distanzierten Ende jeweils eine zur Auflage an einem Schienenfuß vorgesehene Schienenfußnase und eine zwischen Backenhalterung und Schienenfußnase positionierte, jeweils über die Klemmbacke in Richtung zur gegenüberliegenden Klemmbacke vorragende Schienenkopfnase aufweisen, wobei die Distanz zwischen der auf einer gemeinsamen Klemmbacke befindlichen Schienenfuß- und Schienenkopfnase größer ist als die normal zur Schienenlängsrichtung verlaufende Distanz zwischen Schienenkopfunterkante und Schienenfuß der abzuziehenden Schiene.This object is achieved with a generic clamp solved in that two for receiving a rail head and one Rail web spaced apart from the rail to be removed Clamping jaws are provided which are joined together by a jaw holder are connected and at the end further distanced from the jaw holder each a rail foot nose provided for resting on a rail foot and a positioned between the jaw holder and the rail foot nose, in each case via the jaw in the direction of the opposite jaw have protruding rail head nose, the distance between the rail foot and located on a common jaw The rail head nose is larger than that which is normal to the longitudinal direction of the rail Distance between the lower edge of the rail head and the base of the rail to be removed Rail.

Diese spezielle Ausbildung der Klemmzange ermöglicht einerseits eine hohe Klemmwirkung auf die Schiene und erfordert andererseits in Schienenquerrichtung lediglich einen geringen Platzbedarf, so daß auch bei der dichtesten Aneinanderreihung mehrerer Schienen eine problemlose, keine zeitaufwendigen Rüstarbeiten erfordernde Positionierung der Klemmzange zum Abziehen einer einzelnen Schiene möglich ist. Durch die erfindungsgemäße Kombination einer Schienenfußnase mit einer Schienenkopfnase ist bei Übertragung einer Zugkraft auf die Klemmzange automatisch eine optimale kraftschlüssige Verbindung zur Schiene herstellbar, ohne daß dabei die Fahrfläche des Schienenkopfes kontaktiert wird. Dies schafft die vorteilhafte Möglichkeit, auf öffentlichen Waggons zur Baustelle transportierte Langschienen, die bei sehr hohem Reibwiderstand auf Holzzwischenlagen abgestützt sind, rasch und problemlos unter uneingeschränkter Schonung der Fahrfläche von den Waggons abzuziehen.This special design of the clamping pliers enables a high one Clamping effect on the rail and on the other hand requires in the transverse direction of the rail only a small space requirement, so that even the densest Stringing multiple rails together is a hassle-free, no time-consuming Positioning of the clamping pliers for pulling-off which requires setup work a single rail is possible. By the invention Combination of a rail foot nose with a rail head nose is at Optimal transmission of a tensile force to the clamping pliers automatically non-positive connection to the rail can be produced without the Driving surface of the rail head is contacted. This creates the beneficial one Possibility of long rails transported to the construction site on public wagons, which are supported on wooden intermediate layers with very high frictional resistance are quick and easy with unrestricted protection of the driving surface deduct from the wagons.

    • Die in den Fig. 1 bis 5 ersichtliche Klemmzange 1 zur kraftschlüssigen Verbindung mit einer Schiene 2 weist zwei normal zur Schienenlängsrichtung zueinander verschwenkbare Klemmbacken 3 auf. Diese sind um eine in Schienenlängsrichtung verlaufende Schwenkachse 4 verschwenkbar auf einer Backenhalterung 5 gelagert. Jede Klemmbacke 3 weist an einem von der Backenhalterung 5 weiter distanzierten Ende eine zur Auflage an einen Schienenfuß 6 vorgesehene Schienenfußnase 7 auf. Zwischen dieser und der Schwenkachse 4 befindet sich eine in Richtung zur gegenüberliegenden Klemmbacke 3 vorragende, rotationssymmetrisch ausgebildete Schienenkopfnase 8. Die Distanz zwischen der auf einer gemeinsamen Klemmbacke 3 befindlichen Schienenfußnase 7 und der endseitigen Schienenkopfnase 8 ist geringfügig größer als die normal zur Schienenlängsrichtung verlaufende Distanz a (Fig. 1 und 2) zwischen einer Schienenkopfunterkante 9 eines Schienenkopfes 10 und dem Schienenfuß 6.The clamp pliers 1 shown in FIGS. 1 to 5 for the non-positive connection with a rail 2 points two normal to the longitudinal direction of the rail jaws 3 which can be pivoted relative to one another. These are one in Rail axis extending pivot axis 4 pivotable a jaw holder 5 stored. Each jaw 3 points to one of the jaw holder 5 further distanced end to rest on one Rail foot 6 provided rail foot nose 7. Between this and the pivot axis 4 is one in the direction of the opposite Clamping jaw 3 protruding, rotationally symmetrical rail head nose 8. The distance between the one on a common jaw 3 Rail foot nose 7 and the end rail head nose 8 is slightly larger than the distance normal to the longitudinal direction of the rail a (Fig. 1 and 2) between a rail head lower edge 9 of a rail head 10 and the rail foot 6.

    Jede Klemmbacke 3 ist bezüglich ihrer normal zur Schwenkachse 4 verlaufenden Längsrichtung unter Bildung eines Blockierabschnittes 11 über die Schwenkachse 4 hinaus verlängert ausgebildet. Zwischen den beiden Blockierabschnitten 11 der Klemmbacken 3 ist ein Blockierteil 12 um eine Achse 13 verschwenkbar auf der Backenhalterung 5 gelagert.Each jaw 3 is normal to the swivel axis 4 Longitudinal direction to form a blocking section 11 over the Swivel axis 4 also extended. Between the two Blocking sections 11 of the jaws 3 is a blocking part 12 around a Axis 13 pivotally mounted on the jaw holder 5.

    Gemäß Fig. 2 sind die Schienen 2 unter dichter Aneinanderreihung - wie hier der besseren Übersicht halber nicht dargestellt - auf einem Transportwaggon gelagert und auf einer Gleisbaustelle vom Waggon abzuziehen. Dazu wird der Blockierteil 12 der Klemmzange 1 zur Freigabe der Verschwenkbarkeit hochgeschwenkt (s. Fig. 1 bis 3), wonach die beiden Klemmbacken 3 auseinandergeschwenkt werden. In dieser Position ist ein problemloses Einführen jeder Klemmbacke 3 zwischen zwei benachbarten Schienen 2 möglich. Dabei kommen die Schienenkopfnasen 8 und die Schienenfußnasen 7 jeweils zwischen Schienenfuß 6 und Schienenkopf 10 im Bereich eines Schienensteges 21 der abzuziehenden Schiene 2 zu liegen (Fig. 1 bis 3). Als nächstes erfolgt nach geringfügigem Anheben der Klemmzange 1 manuell ein Schließen der beiden Klemmbacken 3 (s. Fig. 4,5) sowie ein Herunterklappen des Blockierteiles 12 zwischen die beiden Blockierabschnitte 11. Damit sind die beiden Klemmbacken 3 nicht mehr verschwenkbar. Sobald nun auf ein Seil 14 eine Zugkraft ausgeübt wird, erfolgt ein geringfügiges Kippen der Klemmzange 1 um die beiden auf dem Schienenfuß 6 aufliegenden Schienenfußnasen 7, bis die beiden Schienenkopfnasen 8 die jeweilige Schienenkopfunterkante 9 des Schienenkopfes 10 kontaktieren. Es kommt damit automatisch zu einer kraftschlüssigen Verbindung der Klemmbacken 3 mit der abzuziehenden Schiene 2. Das hat den besonderen Vorteil, daß sehr hohe Zugkräfte problemlos auf die Schiene 2 übertragbar sind, ohne daß dabei eine Fahrfläche 15 des Schienenkopfes 10 kontaktiert wird. Zum Entfernen der Klemmzange 1 ist lediglich der Blockierteil 12 hochzuschwenken, wonach die beiden Klemmbacken 3 auseinanderspreizbar sind. Danach kann die Klemmzange 1 einfach durch Anheben entfernt und über der nächsten abzuziehenden Schiene 2 abgesenkt werden. According to FIG. 2, the rails 2 are arranged closely together - like not shown here for the sake of clarity - on a transport wagon stored and deducted from the wagon on a track construction site. For this purpose, the blocking part 12 of the clamp pliers 1 to release the pivotability pivoted up (see Fig. 1 to 3), after which the two jaws 3 can be swung apart. In this position is a problem Insert each jaw 3 between two adjacent rails 2 possible. The rail head lugs 8 and the rail foot lugs come here 7 each between the rail base 6 and the rail head 10 in the area a rail web 21 of the rail 2 to be removed to lie (Fig. 1 to 3). The next step is to manually raise the clamp 1 a closing of the two jaws 3 (see Fig. 4.5) and a folding down of the blocking part 12 between the two blocking sections 11. So that the two jaws 3 are no longer pivotable. As soon as now a tensile force is exerted on a rope 14, there is a slight Tilt the clamp 1 around the two resting on the rail base 6 Rail foot lugs 7 until the two rail head lugs 8 each Contact the bottom edge of the rail head 9 of the rail head 10. It is coming thus automatically to a non-positive connection of the clamping jaws 3 with the rail to be removed 2. This has the particular advantage that very high tensile forces are easily transferable to the rail 2 without a running surface 15 of the rail head 10 is contacted. To remove the clamp 1 only has to be swiveled up the blocking part 12, after which the two jaws 3 are spread apart. After that the clamp 1 can be easily removed by lifting and over the next deductible rail 2 are lowered.

    Bei den im folgenden näher beschriebenen weiteren Ausführungsbeispielen einer Klemmzange 1 sind der Einfachheit halber funktionsgleiche Teile mit den im ersten Ausführungsbeispiel verwendeten Bezugszeichen versehen.In the further exemplary embodiments described in more detail below a clamp 1 are for the sake of simplicity functionally identical parts with the reference numerals used in the first embodiment.

    Die in Fig. 6 und 7 ersichtliche, vereinfachte Version einer Klemmzange 1 weist zwei starr mit der Backenhalterung 5 verbundene Klemmbacken 3 auf. Zum Abziehen der Schiene 2 muß die Klemmzange 1 unter Schräglage (s. strichpunktierte Linien in Fig. 6) an einem Schienenende 16 mit den Schienenfuß- und Schienenkopfnasen 7,8 zwischen Schienenkopf 10 und Schienenfuß 6 eingeschoben werden. Sobald auf das Seil 14 eine Zugkraft ausgeübt wird, kommt es wiederum über die Hebelwirkung zu einem Anpressen der Schienenfußnasen 7 an den Schienenfuß 6 und der Schienenkopfnasen 8 an die Schienenkopfunterkante 9. Zum Entfernen der Klemmzange 1 muß diese wiederum unter Schräglage über das Schienenende 16 hinaus in Schienenlängsrichtung verschoben werden.6 and 7, simplified version of a clamp 1 has two jaws 3 rigidly connected to the jaw holder 5. To pull off the rail 2, the clamping pliers 1 must be inclined (see dash-dotted lines in Fig. 6) at a rail end 16 with the Rail foot and rail head lugs 7,8 between rail head 10 and Rail foot 6 are inserted. As soon as a tensile force on the rope 14 is exercised, leverage in turn leads to pressure the rail foot lugs 7 on the rail foot 6 and the rail head lugs 8 to the bottom edge of the rail head 9. To remove the clamp 1 must in turn be inclined beyond the rail end 16 in Rail longitudinal direction are shifted.

    Bei der in Fig. 8 und 9 ersichtlichen Version einer Klemmzange 1 sind die Klemmbacken 3 ebenfalls starr mit der Backenhalterung 5 verbunden. Jede Schienenkopfnase 8 ist auf einer verschwenkbar auf der Klemmbacke 3 gelagerten Halterung 17 befestigt und durch eine Bohrung 18 der Klemmbacke 3 hindurchführbar. Die Verschwenkbarkeit der Halterung 17 um eine Achse 19 ist durch eine verschwenkbar auf der Backenhalterung 5 gelagerte Blockiereinrichtung 20 blockierbar.In the version of a clamp 1 visible in FIGS. 8 and 9, the Clamping jaws 3 are also rigidly connected to the jaw holder 5. Each Rail head nose 8 is mounted on a pivotable on the jaw 3 Bracket 17 attached and through a bore 18 of the jaw 3 can be passed through. The pivotability of the bracket 17 about an axis 19 is pivotally mounted on the jaw holder 5 Blocking device 20 can be blocked.

    Diese Klemmzange 1 kann problemlos auf die abzuziehende Schiene 2 aufgesetzt werden, indem die beiden Schienenkopfnasen 8 jeweils in ihre äußere Schwenkposition (s. Fig. 9) gebracht werden. Nach dem Aufsetzen der Klemmzange 1 können die beiden Schienenkopfnasen 8 zueinander verschwenkt und durch die Blockiereinrichtung 20 blockiert werden. Damit ist bei Aufbringung einer Zugkraft auf die Klemmzange 1 die bereits beschriebene kraftschlüssige Verbindung über Schienenfußnase 7 und Schienenkopfnase 8 herstellbar. Zum Entfernen der Klemmzange 1 sind die Blockierenrichtung 20 und die beiden Schienenkopfnasen 8 zu verschwenken.This clamp 1 can be easily placed on the rail 2 to be removed be by the two rail head lugs 8 each in their outer Swivel position (see Fig. 9) are brought. After putting on the Clamping pliers 1, the two rail head lugs 8 can be pivoted towards each other and are blocked by the blocking device 20. So that is when applying a tensile force to the clamp 1, the one already described non-positive connection via rail foot nose 7 and rail head nose 8 producible. To remove the clamp 1 are the blocking direction 20 and to pivot the two rail head lugs 8.
