Description
Wanderpfeiler Gegenstand des Patents 71.1 182 ist ein aus zwei gegeneinander verschiebbaren Pfeilerteilen bestehender Wanderpfeiler für dic Stützung des Hangenden im Grubenbetrieb, bei dem jeder Pfeilerteil für sich unter das Hangende verspannt ist und bei dem die beiden Pfeilerteile so miteinander gekuppelt sind, daß der nach Lösen der Spannvorrichtung nicht unter Gebirgsdruck stehende Pfeilerteil an dem unter Gebirgsdruck stehenden Pfeilurteil hängend entlang bewegt werden kann,- indem die beiden Pfeilerteile an ihren oberen Teilen mit ineinanderfassende :n Führungsschienen bzw. Führungsrollen oder Gleitlager versehen sind. Hierbei besitzen. die beiden Pfeilerteileeine solche Form, daß die vorderen Kopfteile der Pfeiler so weit über den unteren Fußteil vorragen, daß ein breites Förderfeld zwischen Stoß und Pfeiler entsteht, das gegen Hereinbrechen des Hangenden geschützt ist.Wanderpfeiler The subject of patent 71.1 182 is one of two against each other movable pillar parts of existing hiking piers for supporting the hanging wall in mining operations, where each part of the pillar is braced individually under the hanging wall is and in which the two pillar parts are coupled together that the after Loosen the clamping device on the pier part that is not under rock pressure arrow part standing under mountain pressure can be moved hanging along, - by the two pillar parts at their upper parts with interlocking guide rails or guide rollers or slide bearings are provided. Own here. the two Pillar parts such that the front head parts of the pillar are so far over protrude the lower foot part that a wide conveyor field between the joint and pillar arises, which is protected against collapse of the hanging wall.
Eine besonders .günstigc Ausführungsform derartiger Wanderpfeiler ergibt sich. wenn man gemäß der vorliegenden Erfindung jeden der beiden Pfeilerteile nicht aus einem Stück bestehend, sondef-n mehrteilig ausführt, indem man als tragenden Teil des Pfeilers Stahlstrmpel bekannter starrer oder nachgiebiger Bauart verwendet, die das vorragende Firstenstück tragen, wobei die Stempel mit dem Firstenstück gelenkig verbunden sind. Derartigr Wanderpfeiler haben den Vorteil, daß sie besser dem Hangenden angepaßt werden können, daß bei ungleichmäßigem Druck des Gebirges eine bessere Druckaufnahme durch den Pfeiler erfolgt und daß sie in handlichen Teilen an den Aufstellungsort gebracht werden können.A particularly favorable embodiment of such hiking pillars surrendered. if, according to the present invention, each of the two pillar parts not consisting of one piece, sondef-n executes in several parts by being a load-bearing Part of the pillar steel jacks of known rigid or resilient design used, which carry the protruding roof piece, the stamps being articulated with the roof piece are connected. Such hiking pillars have the advantage that they are better attached to the hanging wall can be adapted so that with uneven pressure of the mountains a better one Pressure is absorbed by the pillar and that they are in manageable parts to the Site can be brought.
In der Zeichnung ist der Erfindunbsgrdanke in einem Ausführungsbeispiel veranschaulicht, und zwar zeigt Abb. 1 den .aus Stahlstempeln und Firstenstück bestehenden Wanderpfeiler in Seitenansicht, während Abb.2 einen Schnitt durch die Verbindungsstelle des Stempels mit dem Firstenstück darstellt.In the drawing, the inventive concept is in one embodiment Illustrates, namely Fig. 1 shows the. consisting of steel stamps and roofing piece Wandering pillar in side view, while Fig. 2 shows a section through the junction of the stamp with the crown piece.
Mit 1 und 2 sind die Stahlstempel be- kannter Bauart bezeichnet, und zwar werden zweckmäßig zwei solcher Stempel nach-i.el)igrr Bauart vertvendet, die mit dem zum Stol.`) vorragenden Firstenstück 3, an denen die Führungsrollen bzw. Führungsschienen befestigt sind, gelenkig verbunden werden. Hierbei ruht das Fir stenstück3 mit Widerlagern .1, die zweckmäßigerweise mit dem Firstenstück ,, fest verbunden . sind, auf dem Stempelkopf. wobei die Stempels und 2 mit dem 3 durch Bolzen 3 gelenkig verbunden sind.1 and 2, the steel die of known type are referred to, and indeed are advantageously two such printed according i.el-) igrr type vertvendet that with the protruding to Stol.`) ridge piece 3 to which the guide rollers or guide rails fastened are to be articulated. Here the Fir stenstück3 rests with abutments .1, which are expediently firmly connected to the Firstenstück. are on the stamp head. the stamps 2 and 2 being articulated to the 3 by bolts 3.
