Description
Vorrichtung zum Vorschieben der Vorpfändkappe eines Strebausbaus In der Hauptpatentanmeldung ist ein am Ende einer Vorpfändkappe angeordnetes Abbauwerkzeug unter Schutz gestellt, dem von rückwärts Schläge und/oder eine hin- und hergehende Bewegung erteilt wird.Device for advancing the pre-pledging cap of a longwall construction In of the main patent application is a mining tool arranged at the end of a pre-pledging cap placed under protection from backward blows and / or a reciprocating Movement is granted.
Die Erfindung befaßt sich mit einer zweckmäßigen Ausgestaltung dieser Abbaueinrichtung und schlägt vor, den Vorschub der Vorpfändkappe durch einen Winkelhebel zu bewirken, dessen einer Arm als Rohr für den darin einschiebbaren Vorschubarrn für die Vorpfändkappe ausgebildet ist und dessen anderer Arm über Gelenke mit dem etwa senkrecht stehenden Vorschubzylinder verbunden ist.The invention is concerned with an expedient embodiment of this Dismantling device and suggests the advance of the pre-pledging cap by means of an angle lever to cause one arm of which as a tube for the feed arm that can be inserted therein is designed for the Vorpfändkappe and whose other arm has joints with the is connected approximately perpendicular feed cylinder.
Da die Abbauwerkzeuge an der Vorpfändkappe bei der Arbeit einen gewissen Rückdruck erzeugen, ist es notwendig, die Kappe mit einer zusätzlichen Vorschubkraft zu versehen, damit die Werkzeuge intensiv an der Beseitigung von Vorsprüngen arbeiten können, die den gesamten Vorschub des Ausbaues behindern.Because the dismantling tools on the pre-pledging cap at work have a certain amount To generate back pressure, it is necessary to push the cap with an additional pushing force to be provided so that the tools work intensively on removing protrusions that hinder the entire advance of the expansion.
Wegen der wechselnden Flözmächtigkeit muß, wie angegeben, der den Vorschub bewirkende Arm in sich verlänger- und verkürzbar sein. Um nun die Energiezufuhr zu den Abbauwerkzeugen einfach zu gestalten, wird nach einem weiteren Merkmal der Erfindung vorgeschlagen, sie durch die hohl ausgebildeten Vorschubarme zu leiten.Because of the changing seam thickness, as indicated, the The feed effecting arm can be extended and shortened in itself. Now about the energy supply To make the mining tools easy to use is another feature of the Invention proposed to guide them through the hollow feed arms.
Die Figuren zeigen ein Ausführungsbeispiel der Erfindung.The figures show an embodiment of the invention.
F i g. 1. zeigt die Vorrichtung in einem Strebquerschnitt und F i g. 2 die Vorrichtung vom Kohlenstoß aus gesehen.F i g. 1. shows the device in a longwall cross-section and FIG . 2 the device seen from the coal face.
Die an der Vorpfändkappe 3 angeordneten Abbauwerkzeuge 13 werden durch den Zylinder 5 betätigt, dessen Energiezufuhr über die Leitungen 21, den Vorschubarm 1 und die Leitungen 15, 14 erfolgt und durch den Hahn 12 derart aesteuert wird, daß gleichzeitig mit dem Vorschubzylinder 22 auch der Vorschubzylinder 8 über die Leitung 16 beaufschlagt wird, der, mit der Fördereinrichtung 9 verbunden, über ein Gelenk am Gestell 7 angreift bzw. am Sternpelfuß 10 des Stempels 2, dessen ausziehbarer Teil 4 die Vorpfändkappe 3 trägt.The dismantling tools 13 arranged on the pre -pledging cap 3 are actuated by the cylinder 5 , the energy of which is supplied via the lines 21, the feed arm 1 and the lines 15, 14 and is controlled by the cock 12 in such a way that the feed cylinder 22 is also controlled at the same time as the feed cylinder 22 8 is acted upon via the line 16 , which, connected to the conveyor 9 , engages the frame 7 via a joint or the star base 10 of the stamp 2, the extendable part 4 of which carries the pre-pledging cap 3.
Die Kolbenstange 18 des etwas senkrecht stehenden Vorschubzylinders 22 greift über das Gelenk 19 an dem Winkelhebelarm 20 an, welcher durch das mit dem Gestell 7 verbundene Gelenk 6 mit dem als Rohr 23 ausgebildeten Hebelarm 17 verbunden ist. Beim Vorschub des Gestelles 7 durch den Zylinder 8 bzw. des Stempels aus der Lage 11 in die Lage 10 wird gleichzeitig der Zylinder 22 betätigt, und so bewirken die beiden Zylinder 8 und 22 die Vorschubbewegung.The piston rod 18 of the somewhat vertical feed cylinder 22 engages via the joint 19 on the angle lever arm 20, which is connected to the lever arm 17 designed as a tube 23 through the joint 6 connected to the frame 7 . When the frame 7 is advanced by the cylinder 8 or the ram from the position 11 into the position 10 , the cylinder 22 is actuated at the same time, and so the two cylinders 8 and 22 effect the feed movement.
