Description
Die Erfindung betrifft eine mehrteilige teleskopartige Spreizstütze zum Abstützen von Grubenbauen gegeneinander beim Auffahren von Strecken und Querschlägen, bei der die gegeneinander verschiebbaren Teile unter Federdruck stehen.The invention relates to a multi-part telescopic spreader support to support pit structures against each other when driving up routes and crosscuts, in which the mutually displaceable parts are under spring pressure.
In Strecken und Querschlägen von Bergwerken sind die Grubenäusbaue, meist bestehend aus zwei Stempeln mit darüberliegender Kappe, durch Holzbolzen horizontal so gegeneinander abgestützt, daß ein Verschieben bzw. Umfallen derselben verhindert wird. Beim Schießbetrieb zum Vortreiben der Querschläge bzw. Strecken werden die letzten Baue durch die Erschütterung stark bewegt, so daß die starren Holzbolzen herunterfallen. Dadurch fällt der nun nicht mehr abgestützte Bau um und reißt mitunter andere mit. Das dadurch hereinbrechende Hangende erfordert dann kostspielige Arbeiten und Zeitverlust. Bisher wird eine geringe Abhilfe durch Festnageln der Bolzen am Stempel erreicht.In stretches and crosscuts of mines are the pit structures mostly consisting of two stamps with an overlying cap, horizontally through wooden bolts supported against each other in such a way that they are prevented from shifting or falling over will. When shooting to advance the cross passages or routes, the last building moved strongly by the vibration, so that the rigid wooden bolts falling off. As a result, the building, which is no longer supported, falls over and sometimes tears others with. The resulting hanging wall then requires expensive work and loss of time. So far, a small remedy is to nail the bolts to the Stamp achieved.
Bei der Spreizstütze nach der Erfindung wird diese Gefahr dadurch behoben, daß durch ihre Elastizität dieselbe den Bewegungen der Baue folgen kann und somit ein Umfallen verhindert.With the brace according to the invention, this risk is eliminated remedied that through its elasticity it can follow the movements of the structures and thus prevents it from falling over.
In der Zeichnung ist die Erfindung näher erläutert.The invention is explained in more detail in the drawing.
Auf den Rohrstutzen 7 werden an beiden Enden Rohrstücke 6 aufgesetzt, die einen solchen Durchmesser haben, daß sie mit geringem Spiel auf dem Rohrstutzen 7 verschoben werden können. An den aufgesetzten Rohrstücken 6 ist je sein Flansch i bzw. 2 vorgesehen. Diese Flansche i bzw. 2 sind durchbohrt und mittels Bolzen 3 mit- und gegeneinander verschiebbar verbunden. Die Bolzen 3 sind durch Muttern 5 gegen Verlieren gesichert. Zwischen den Flanschen i und 2 ist die die Rohrstücke 6 und den Rohrstutzen 7 umfassende Schraubenfeder ,4 so angeordnet, daß ihre Federkraft die Rohrstücke 6 auseinanderdrückt. Ein Stift 15 begrenzt die seitliche Bewegung des Rohrstutzens.On the pipe socket 7 pipe pieces 6 are placed at both ends, which have such a diameter that they have little play on the pipe socket 7 can be moved. On the attached pipe pieces 6 is each its flange i and 2 are provided. These flanges i and 2 are pierced and bolted 3 connected with and against each other displaceable. The bolts 3 are through nuts 5 secured against loss. Between the flanges i and 2 is the pipe sections 6 and the pipe socket 7 comprehensive coil spring, 4 arranged so that their spring force pushes the pipe sections 6 apart. A pin 15 limits the lateral movement of the pipe socket.
In den aufgeschobenen Rohrstücken 6 sind an den freienEnden weitere, mit Spiel bewegbare kurze Rohre 9 vorgesehen. Die Rohrstücke 6 und die Rohre 9 weisen Bohrungen a auf und sind in bezug auf ihre Verschiebbarkeit gegeneinander durch einen in diese Bohrungen a eingepaßten Stift 8 einstellbar. An den äußeren Enden der innenliegenden Rohre 9 ist je ein Bund 16 aufgeschweißt, der als Auflage für die Mutter i i dient. Das in die Rohre 9 ragende Spindelende io sichert und versteift gleichzeitig die Rohre 9 gegen Biegung und Knickung. Die verstellbare Spannspindel 17 ist durch den Bolzen 14 und die Schraubenmutter 13 gelenkig mit dem halbkreisförmigen Druckteller 12 verbunden. Alle Schweißstellen sind mit b bezeichnet.In the pushed-on pipe pieces 6, further short pipes 9 which can be moved with play are provided at the free ends. The pipe sections 6 and the pipes 9 have bores a and can be adjusted with respect to their displaceability relative to one another by a pin 8 fitted into these bores a. At the outer ends of the inner tubes 9, a collar 16 is welded, which serves as a support for the nut ii. The spindle end protruding into the tubes 9 secures and stiffens the tubes 9 against bending and kinking at the same time. The adjustable clamping spindle 17 is articulated to the semicircular pressure plate 12 by the bolt 14 and the screw nut 13. All welds are marked with b.
Die gelenkige Verbindung von Druckteller 12 und Spannspindel 17 ermöglicht einerseits das Anpassen des Drucktellers 12 an schräg stehende Grubensterripel, und andererseits verhindert sie ein Verdrehen der Spannspindel. Beim Einbringen der verstellbaren und nachgiebigen Spreizstütze wird die Spannmutter angezogen, bis eine angemessene Vorspannung erreicht ist. Durch die erfindungsgemäße Anordnung der frei um die Stütze liegenden Feder ist ein Auswechseln derselben vor Ort jederzeit und schnell durchführbar, da jeweils nur ein Rohrstück 6 abgezogen zu werden braucht.The articulated connection of pressure plate 12 and clamping spindle 17 enables on the one hand, the adaptation of the pressure plate 12 to inclined pit triple, and on the other hand, it prevents the clamping spindle from rotating. When bringing in the adjustable and flexible spreader support is tightened, until an adequate preload is achieved. By the arrangement according to the invention The spring lying freely around the support can be replaced on site at any time and can be carried out quickly, since only one pipe section 6 needs to be pulled off at a time.
