Description
Einrichtung zur Abschirmung des Hangenden in Abbauörtern oder Streckenvortrieb Vorliegende Erfindung betrifft eine Einrichtung zur Abschirmung des Hangenden in Abbauörtern oder Strecken nach: Patent 482 265. Durch dieses Patent ist eine Einrichtung geschützt, die sich als Einzelschirm darstellt und somit einen Schutz für einen Hauer, bei besserem Gebirge vornehmlich im Streckenvortrieb, abgeben kann. Von einem mehr oder minder breiten oder langen Abbaustoß bei schlechtem Gebirge eignet sich diese Einrichtung aber nicht. Um diesem Umstande Rechnung zu tragen, mußte wieder auf den provisorischen Spitzenverzug zurückgegriffen werden, wobei .aber gemäß der Erfindung das Gestell-des Schirmes nach dem Hauptpatent als Träger für diesen provisorischen Ausbau benutzt wird. Und zwar werden nur zwei gegenüberliegende Tragarme oder Tragstangen benutzt, welche möglichst parallel dem Stoß aufgestellt , werden, über welche dann senkrecht zum Arbeitsstoß Verzugspitzen vorgestreckt werden. Mit dem Fortschreiten des Abbaus werden zweckmäßig zwei oder mehr solcher Schirmgestelle benutzt, welche .aneinander anschließen und den Stoß in der ganzen Breite sichern. Die Schirme werden dann entsprechend mit dem Herankommen des Bergeversatzes oder dem definitiven Ausbau fortgenommen oder gegen den letzteren ausgewechselt.Device for shielding the hanging wall in excavation sites or drifting The present invention relates to a device for shielding the hanging wall in Mining points or routes according to: Patent 482 265. This patent is a facility protected, which presents itself as a single screen and thus a protection for one Hauer, with better mountains, primarily in drifting, can give up. Of a more or less wide or long mining face in poor rock is suitable but not this facility. To take this into account, I had to do it again the provisional peak delay can be used, but according to the Invention of the frame of the umbrella according to the main patent as a carrier for this provisional Expansion is used. There are only two opposite support arms or support rods used, which are set up as parallel to the joint as possible, over which then Warpage peaks are pre-stretched perpendicular to the working joint. As you progress of the dismantling, two or more such umbrella frames are expediently used, which . connect to each other and secure the joint over the entire width. The umbrellas will then accordingly with the approach of the mountain offset or the definitive expansion taken away or exchanged for the latter.
Die neue Firstabstützung ist nun im wesentlichen dadurch gekennzeichnet, daß an der Spannsäule zwei einander gegenüberliegende, in senkrechter Ebene schwenkbare und verstellbare Arme vorgesehen sind, die mit dem vorschreitenden Abbau nacheinander rechtwinklig zur Spannsäule .aufgerichtet werden, um an Stelle der üblichen Schalhölzer die Spitzen des provisorischen Ausbaues zu tragen.The new ridge support is now essentially characterized by that on the tensioning column two opposing, pivotable in a vertical plane and adjustable arms are provided, which one after the other with the progressing dismantling at right angles to the tensioning column. be erected to replace the usual formwork timber to carry the tips of the temporary extension.
In der beiliegenden Zeichnung ist Rin Ausführungsbeispiel dargestellt.In the accompanying drawing, an exemplary embodiment is shown.
Es zeigen Fig. i im Aufriß die Firstabstützung im Abbauort, Fig. 2 einen Grundriß zu Fig. i, Fig. 3 in vergrößertem Maßstabe eine Ausführungsform des Schirmgestelles, Fig. q eine andere Ausführungsform des Schirmgestelles. -Das Schirmgestell besteht aus einer nach Art einer Spannsäule- ausgebildeten Hauptsäule a. Der obere, ausziehbare Teil a' hat in seinem oberen Ende ein als Schraubenspindel ausgebildetes Kopfstück b; welche durch eine Mutter b' in verschiedener Höhenlage :eingestellt und festgehalten wird. In diesem Kopfstück ist ein Querträger r aus Profileisen befestigt, dessen als Tragarme dienenden Enden klappbar, also in vertikaler Ebene schwenkbar, ausgebildet sind. Diese Arme werden durch Streben d, die m einer auf dem Teil a' verschiebbaren und feststellbaren Schelle e klappbar befestigt sind, abgestützt. Die den Querträger bildenden Arme sind derart ,ausgebildet, daß sie durch Ansatzstücke r" verlängert werden können. In Fig. q. ist eine andere Ausführungsform des Kopfstückes b" der Schraubenspindel dargestellt, insofern dasselbe gabelförmig ausgebildet ist, um so den Mittelteil des Querträgers, der durch den Gebirgsdruck am meisten beansprucht wird, eine bessere Unterstützung und somit größere Tragfähigkeit zu geben.1 shows the ridge support at the dismantling site in elevation, FIG. 2 shows a plan view of FIG. I, FIG. 3 shows an enlarged scale embodiment of the umbrella frame, FIG. Q another embodiment of the umbrella frame. The umbrella frame consists of a main column designed in the manner of a tensioning column a. The upper, extendable part a ' has in its upper end a head piece b designed as a screw spindle; which by a nut b 'at different heights: is set and held. In this head piece, a cross member r made of profile iron is fastened, the ends of which serving as support arms are designed to be foldable, that is to say pivotable in the vertical plane. These arms are supported by struts d which are hingedly attached to a clamp e which can be displaced and locked on part a '. The arms forming the crossbeam are designed in such a way that they can be lengthened by extension pieces r ". In Fig. Q. Another embodiment of the head piece b" of the screw spindle is shown, insofar as it is fork-shaped so that the central part of the crossbeam, which is most stressed by the rock pressure to give better support and thus greater load-bearing capacity.
Dieser Querträger bzw. die Arme, welche mit dem Fortschreiten des Abbaues nazheinander ..aufgeklappt werden, dienen zur Auflagerung des, provisorischen Ausbaues, also der Spitzen oder Schalhölzer.This cross member or the arms, which with the progression of the Dismantling next to each other .. are used to support the, provisional Expansion, i.e. the tops or formwork timbers.
