Abstract

The stowing shield for mixing is mounted ahead of a roof support (13) and interconnected by a common hydraulic circuit. A lower part (6) moves inside an upper part (7), with a piston and cylinder (12) between them. Attached to a pivot point at the top of each part are respective pistons of actuator cylinders (9, 10) mounted at the bottom on a floor member. Attached to the bottom of the lower part (6) is the piston of a horizontal cylinder (8) also mounted on the floor member, extending forwards from it. The cylinders for the upper parts are connected to a common connection of the hydraulic circuit. The top front corner of the lower part (6) is rounded where it approaches the interior of the rounded part of the upper part (7).

Description

Der Gegenstand des Hauptpatentes betrifft eine Versatzschitdanordnung hinter einem mechanisierten, also selbstwandernden Ausbau unter Abstützung des Versatzschildes durch Stempel, dergestalt, daß an den Sohlschienen bzw. an den Stempelfüßen des mechanisierten Ausbaues Zylinder mit Kolben gelenkig angeordnet sind, die mit dem oberen bzw. dem unteren Teil des Versatzschildes gelenkig verbunden sind.The subject of the main patent relates to an offset cutting arrangement behind a mechanized, So self-wandering expansion with the support of the offset plate by stamp, such that to the Bottom rails or articulated cylinders with pistons at the punch feet of the mechanized expansion are arranged, which are articulated to the upper and the lower part of the offset shield.

Es ist bekannt, zur Abschirmung des Versatzes einen zweiteiligen Schild anzuordnen, der durch einen Stempel mit seinem oberen Teil gegen das Hangende gedrückt wird, wobei der Fuß des Stempels mit dem unteren Teil des Schildes verbunden ist.It is known to arrange a two-part shield to shield the offset, which by a The upper part of the punch is pressed against the hanging wall, the foot of the punch with the lower part of the shield is connected.

Gemäß dem Hauptpatent werden folglich zwei Zylinder parallel über dem Liegenden am unteren Teil des Versatzschildes angreifend und zwei weitere Stempel am Schildoberteil angreifend jeweils am Fuß des mechanisierten Ausbaues angeordnet. Hierdurch bildet der Versatzschild eine in sich unabhängig vom mechanisierten Ausbau steuerbare Einheit, die insbesondere das Hangende gerade dann unterfängt, wenn der mechanisierte Ausbau wanden, also einer der Rahmen vom Hangenden gelöst ist.According to the main patent, two cylinders are consequently parallel over the lying on the lower part attacking the offset shield and attacking two more stamps on the upper part of the shield, each on the foot the mechanized expansion arranged. As a result, the offset shield forms an in itself independent of the mechanized expansion controllable unit, which in particular underpins the hanging wall when the mechanized expansion winds, so one of the frames is detached from the hanging wall.

Wesentlich ist also die Unabhängigkeit des Versatzschildes vom mechanisierten Ausbau, mit dem er nur über Zylinder bzw. Stempel verbunden ist. Diese Zylinder und Stempel können entsprechend gesteuert gleichzeitig als Vorschubzylinder für die Ausbaurahmen dienen. Hierzu ist es nicht unbedingt notwendig, daß der am Schildkopf angreifende Zylinder mit der Sohlschiene des wandernden Rahmens verbunden ist, er kann auch am Fußstück eines Stempels des Wanderrahmens angreifen.It is therefore essential that the offset shield is independent of the mechanized expansion with which it is only is connected via cylinder or punch. These cylinders and rams can be controlled accordingly at the same time serve as a feed cylinder for the extension frame. For this it is not absolutely necessary that the The cylinder attacking the shield head is connected to the bottom rail of the moving frame, he can also attack the foot of a stamp of the hiking frame.

Um nun auch die eingangs genannten, mittels Stempel ineinander verschiebbaren Schildteile in Weiterbildung der Abstützung nach dem Hauptpatent am Ausbau abzustützen, sieht die vorliegende Erfindung vor, daß jeweils am Ausbauunterteil angelenkte Zylinder am Fuße des unteren Schildes, Zylinder am oberen Teil des unteren Schildes und Zylinder am oberen Teil des oberen Schildes angreifen.In order to now also develop the shield parts which can be slid into one another by means of a stamp To support the support according to the main patent on the expansion, the present invention provides that Cylinder at the foot of the lower shield, cylinder at the upper part of the Attack the lower shield and cylinder on the upper part of the upper shield.

Nach einem weiteren Merkmal der Erfindung ist ίο dabei vorteilhaft, daß die Druckräume der jeweils an den oberen Teilen der Schilde angreifenden Zylinder miteinander verbunden sind. Diese Zylinder können folglich gemeinsam gesteuert werden, wohingegen der mil dem unteren Teil des unteren Schildes verbundene Zylinder hiervon getrennt steuerbar ist. In diesem Zusammenhang ist es dann von Vorteil, daß der untere Schild oben zur Auflage des oberen Schildes abgerundet ist.According to a further feature of the invention, it is advantageous that the pressure chambers of each of the the cylinders attacking the upper parts of the shields are interconnected. These cylinders can consequently be controlled jointly, whereas the one connected to the lower part of the lower shield Cylinder can be controlled separately from this. In this context it is then advantageous that the lower Shield is rounded at the top to support the upper shield.

Ein Vorteil der erfindungsgemäßen Ausbildung liegt darin, daß der untere Teil des unteren Schildes unter dem Schutz des oberen Schildes nachgezogen werden kann. Hierbei besteht also die Möglichkeit, daß der untere Schild in Form einer selbstständigen Einheit mit dem mechanisierten Ausbau gelenkig und verschiebbar gesteuert verbunden ist. Der obere Schild kann dann im Rahmen eines Folgeschrittes nachgezogen werden, wobei er sich über die Rundung im oberen Bereich des unteren Schildes abwinkein kann.An advantage of the design according to the invention is that the lower part of the lower shield is below the protection of the upper shield can be tightened. So there is the possibility that the lower shield in the form of an independent unit with the mechanized expansion articulated and movable is connected controlled. The upper shield can then be tightened as part of a subsequent step, where he can bend over the curve in the upper area of the lower shield.

Nach der Erfindung wird also der obere Schild genauso wie der untere Schild jeweils durch zwei Zylinder abgestützt, wobei die Abstützung des unteren Schildes jedoch unmittelbar am Ausbau, die AbstützungAccording to the invention, the upper shield is just like the lower shield by two Cylinder supported, the support of the lower shield, however, directly on the expansion, the support

des oberen indessen durch den am unteren Schild angreifenden Zylinder und den am Ausbau angreifenden erfolgt.of the upper one, however, by the cylinder attacking the lower shield and the cylinder attacking the extension he follows.

Durch die erfindungsgemäße Abstützung wird eine derartige Gelenkigkeit hergestellt, daß durch wahlweise Steuerung sämtlicher Zylinder allen Bruchbauverhältnissen Genüge getan werden kann.By the support according to the invention such agility is produced that by optionally Control of all cylinders all fracture construction conditions can be met.

Um die Schilde sicher im Einfallen abzufangen, ist es zweckmäßig, jeweils zwei Zylinder nebeneinander anzuordnen.In order to safely intercept the shields as they collapse, it is advisable to have two cylinders next to each other to arrange.

Die Zeichnung zeigt ein Ausführungsbeispiel im Strebquerschnitt.The drawing shows an embodiment in the face cross-section.

Im Fußbereich des mechanisierten Ausbaues 13 sind die Zylinder 8,9 und 10 gelenkig befestigt. Hierbei stützt der Zylinder 8 den unteren Teil eines unteren Schildes 6, der Zylinder 9 den oberen Teil des unteren Schildes 6 und der Zylinder 10 den oberen Teil eines oberen Schildes 7. Beide Schildteile 6 und 7 werden durch einen weiteren Zylinder 12 zwischen Hangendem und Liegendem verspannt.In the foot area of the mechanized expansion 13, the cylinders 8, 9 and 10 are articulated. This supports the cylinder 8 the lower part of a lower shield 6, the cylinder 9 the upper part of the lower shield 6 and the cylinder 10 the upper part of an upper shield 7. Both shield parts 6 and 7 are through a another cylinder 12 clamped between hanging and lying.

Sämtliche Zylinder können durch ein Steuerventil 5 unabhängig voneinander gesteuert werden. Es ist jedoch auch möglich, die Druckräume 11 der Zylinder 9 und 10 über Leitungen 3, 4 miteinander zu verbinden und gemeinsam zu steuern, während der Zylinder 8 über die Leitungen 1 und 2 getrennt hiervon steuerbar ist.All cylinders can be controlled independently of one another by a control valve 5. It is however, it is also possible to use the pressure chambers 11 of the cylinders 9 and 10 to connect to each other via lines 3, 4 and jointly control, while the cylinder 8 via the lines 1 and 2 can be controlled separately.

Die Zeichnung veranschaulicht nur eine Versatzschildanordnung. Zweckmäßig ist es jedoch, die Stempelanordnung doppelt auszubilden und so hinter einem Gespann des mechanisierten Ausbaues einen breiten Schild nachzuführen.The drawing illustrates only an offset shield arrangement. It is useful, however, to design the stamp arrangement twice and so behind to follow a team of mechanized expansion with a wide shield.
