Description

Die Erfindung betrifft eine aus zwei in einem gemeinsamen Zylinder verschiebbaren und durch ein !unförmiges oder flüssiges Druckmittel entgegengesetzt zueinander bewegten Kolben bestehende Zugvorrichtung, welche beispielsweise zum Raub'ein von Grubenstempeln in Bergwerken wie aber auch für alle anderen Zwecke dienen soll, bei denen ein Zug auf mechanischem Wege ausgeübt werden soll. Ihr Kennzeichen besteht darin, daß die eine Kolbenstange mit einer Verlängerung teleskopartig in der anderen Kolbenstange geführt ist. Durch eine derartige gegenseitige Führung der Kolbenstangen werden die Stopfbüchsen zu einem erheblichen Teil von den bei Zugvorrichtungen dieser Art zumeist quer zum Zylinder gerichteten Zugkräften entlastet, wodurch die Dichthaltung der Stopfbuchsen entsprechend erleichtert ist. Außerdem ermöglicht jene Führung der Kolbenstangen aneinander, sie sowie die Kolben leichter zu bemessen als solches ohne eine derartige Kolbenstangenführung möglich sein würde; eine Gewichtsersparnis spielt bei diesen tragbaren und z. B. unter Tage in engen Grubenraum en zu befördernden Vorrichtungen eine wesentliche Rolle.The invention relates to one of two displaceable in a common cylinder and by a misshapen or fluid one Piston moving in opposition to each other with pressure means existing pulling device, which, for example, for robbing pit punches in mines as well as for all other purposes in which a train is exercised by mechanical means shall be. Their characteristic is that one piston rod with an extension telescopically in the other Piston rod is guided. By such mutual guidance of the piston rods the stuffing boxes are to a large extent influenced by the pulling devices this type mostly transverse to the cylinder tensile forces relieved, whereby the The sealing of the stuffing boxes is made easier accordingly. It also enables that Guiding the piston rods together, making them and the pistons easier to measure than such would be possible without such a piston rod guide; a weight saving plays with these portable and z. B. to be transported underground in narrow pit spaces Devices play an essential role.

Die Zeichnung veranschaulicht in Abb. 1 die Vorrichtung in einem Längsschnitt und in Abb. 3 in einem Querschnitt nach der Linie A-B der Abb. 1; Abb. 2 zeigt die Kolben und Kolbenstangen gesondert.The drawing illustrates in Fig. 1 the device in a longitudinal section and in Fig. 3 in a cross section along the line AB of Fig. 1; Fig. 2 shows the pistons and piston rods separately.

Der Zylinder 2 der Zugvorrichtung enthält zwei in bezug zueinander verschiebbare Kolben 8, welche aus zwei eine Dichtung 7 zwischen sich fassenden Teilen bestehen kann. Das Druckmittel, welches luftförmig oder auch flüssig sein kann, wird den beiden Zylinderräumen durch einen Eintrittsstutzen 1 hindurch zugeführt. Die eine der Kolbenstangen 14 ist mit einer Verlängerung 12 versehen, mit welcher sie teleskopartig in die andere entsprechend hohle Kolbenstange 5 eingreift. Zwischen die beiden Kolben ist auf den Kolbenstangen eine Feder 15 eingefügt, welche die Bewegung der beiden Kolben gegeneinander federnd auffängt. Wird der Zylinder mittels eines an den Eintrittsstutzen 1 angeschlossenen Dreiweghahns entlüftet, so entfernen sich die beiden Kolben voneinander unter der Wirkung der an den Kolbenstangen angreifenden Zugkräfte; sie können statt dessen aber auch von Hand in ihre Ursprungsstellung zurückgezogen werden; auf den Kolbenstangen angeordnete Federn 9 dienen hierbei zur Hemmung der Kolbenbewegung gegen die Zylinderdeckel 4; letztere besitzen in üblicher Weise eine Stopfbüchsendichtung 3 für die durch sie hindurchtretenden Zugstangen.The cylinder 2 of the pulling device contains two pistons which can be displaced with respect to one another 8, which can consist of two parts grasping a seal 7 between them. The pressure medium, which can be air or liquid, is the two cylinder chambers fed through an inlet nozzle 1 therethrough. One of the piston rods 14 is provided with an extension 12, with which it telescopes into the other correspondingly hollow piston rod 5 intervenes. A spring 15 is inserted between the two pistons on the piston rods, which resiliently absorbs the movement of the two pistons against each other. Will the Cylinder vented by means of a three-way valve connected to the inlet nozzle 1, see above the two pistons move away from each other under the action of the piston rods applied tensile forces; Instead, they can also be returned to their original position by hand be withdrawn; Springs 9 arranged on the piston rods serve to inhibit the piston movement against the cylinder cover 4; the latter have a stuffing box seal in the usual way 3 for the tie rods passing through them.
