Streckenausbau-Abstützvorrichtung Zusatz zu ....... Extension support device addendum to .......

In der Hauptanmeldung wird ein Schutz für eine Streckenausbauabstützvorrichtung begehrt, deren Abstützelemente mit Schreitwerken versehen sind und mit einem kippsicher auf der Streckensohle ruhenden Gestell, an dessen ei -nenv dem Streckenförderer zu zeigenden Ende ein Schreitwerk und an dessen anderem, dem Streckenstoß zu zeigenden Ende ebenfalls ein Schreitwerk angeordnet ist und dessen Kopf mindestens zwei Stempel trägt, die ein die Streckenfirste unterstützendes Schreitwerk halten.In the main application, a protection for a road support device coveted whose support elements are provided with walking mechanisms and with a tip-proof The frame resting on the bottom of the track, on the one of which the track conveyor is attached To be shown end a walking device and at the other end, to be shown the route joint At the end there is also a walking mechanism and its head has at least two stamps who hold a treadwork supporting the ridge.

Diese Anordnung ist mit dem Fördererantrieb unverschiebbar verbunden. Es werden nicht mehr wie bisher zwei Systeme nötig, um die Firste zu halten, so daß die ganze Anlage wesentlich geringeren Raum beansprucht. Erfindungsgemäß werden nun drei in Dreiecksform angeordnete und mit Schreitwerken versehene Gestelle angeordnet, von denen das eine Gestell dem Förderer-Austrag gegenüber liegt, die beiden anderen Gestelle beiderseits des Strebausganges am Strekenstoß, wobei die Gestelle untereinander durch Brücken verbunden sind, die die Stempel tragen, welche die Streckenfirste unterstützen. Durch diese Anordnung wird die Streckenfirste an der Stelle gehalten, an der zum Durchlaß des Strebförderers die Standeisen weggenommen worden sind. Die vom Strebfdrderer herrührenden Längs -kräfte werden von den beiderseits des Strebausganges angeordneten Shreitwerken abgefangen, die sich an diesen Stellen an den noch vollständigen oder wieder vervollständigten Ausbaubögen abstützen können. Zweckmäßigerweise übergreifen die Brücken den Streckenförderer. Da nun auf der Streckensohle einfache, meist wenig wellige Oberflächen sind, genügt hier ein Schreitwerk, das nur eine heb- und senkbare Schiene besitzt. An der Streckenfirste in -dessen muß eine besonders sorgsame Unterfangung stattfinden, weshalb erfindungsgemäß vorgeschlagen wird, an dieser Stelle ein Doppelsystem an -zuordnen, das aus einem von den. Stempeln getragenen Kasten besteht, an dem beiderseits auf die Länge des Kastens verteilt einzelne unabhängigo voneinander arbeitende Hubwerke angeordnet sind, welche ihrerseits Unter -stützungssshienen tragen. Indem so in an sich bekannter Weise durch wechselweise Auflastung des Kastens und der Einzelhubwerke beide Systeme relativ zueinander verschoben werden können, .wie dies in der Hauptanmeldung beschrieben ist, kann das @anzen-4 auch den Fördererantrieb haltende System gerückt werden, ohne daß beim Rücken die Firstabstützung unterbrochen wird. Der von den Stempeln gehaltene Kasten ist länger als die Streböffnung breit ist und die von ihm getragenen Schienen greifen noch darüberhinaus.This arrangement is immovably connected to the conveyor drive. Two systems are no longer necessary to hold the roof, as was previously the case that the whole system takes up much less space. Be according to the invention now three racks arranged in a triangular shape and provided with walking mechanisms, One of the frames is opposite the conveyor discharge, the other two Racks on both sides of the longwall gangway at the line joint, with the racks below one another are connected by bridges that carry the stamps that make up the ridge support. This arrangement keeps the ridge in place from which the level iron has been removed to allow the face conveyor to pass through. the Longitudinal forces originating from the longwall are caused by the two sides of the face wall arranged Shreitwerke intercepted, which are at these points on the still complete or can support completed extension arches. Appropriately overlap the bridges the conveyor belt. Since now on the track sole simple, mostly little are wavy surfaces, a walking frame is sufficient here, which can only be raised and lowered Owns rail. Particularly careful underpinning must be carried out at the ridge of the route take place, which is why it is proposed according to the invention, a double system at this point to assign the one from one of the. Stamping worn box consists on which on both sides along the length of the box, some are distributed independently of each other working hoists are arranged, which in turn support support rails wear. By doing so in a manner known per se alternating charging the box and the single hoist both systems are moved relative to each other can, as described in the main application, the @ anzen-4 can also the system holding the conveyor drive can be moved without the ridge support at the back is interrupted. The box held by the punches is longer than the face opening is wide and the rails carried by it extend beyond it.

Die Zeichnungen zeigen Ausführungsbeispiele: Fig. 1 eine Ansicht auf die Streböffnung zu Fig. 2 einen Grundriß ohne das Firstschreitwerk und ohne den Fördererantrieb und Fig. 3 die Vorrichtung im Streckenquerschnitt.The drawings show exemplary embodiments: FIG. 1 shows a view the longwall opening to FIG. 2 is a plan without the ridge treadmill and without the Conveyor drive and FIG. 3 shows the device in section cross-section.

Die sih an der Streckensohle und dem Streckenstoß abstützenden Schreitwerke, die in den Gestellen 1 und 2 angeordnet sind, sind durch die Brücken 4 und 6 mit dem Gestell 3 verbunden, das ein Schreitwerk trägt, welches sich auf der Streckensohle abstützt. Zwischen den beiden Brücken befindet sich der Kohleaustrag aus dem Streb- in den Streckenförderer. Die An -triebsstation 9 kann an den Brücken aufgehängt werden. Die von ihr ausgehenden Kräfte nimmt das Schreitwerk 17 auf. Die Shreitwerke stützen sich auf den Schienen 8j18 ab. Auf den Brüken 4j6 stehen die Stempel 7. Es können auch zwei zueinander geneigte Stempel 7' sein, die durch die Stützelemente 19 bankrecht gehalten werden. Sie tragen das Firstschreitwerk.The treadworks, which are supported on the track bottom and the track joint and are arranged in the frames 1 and 2, are connected by the bridges 4 and 6 to the frame 3, which carries a walking frame which is supported on the track bottom. The coal discharge from the face to the line conveyor is located between the two bridges. The drive station 9 can be hung on the bridges. The forces emanating from it are absorbed by the walking mechanism 17. The Shreitwerke support each other on the rails 8j18. The stamps 7 are on the bridges 4j6. Two can also be related to each other be inclined stamps 7 ', which are held by the support elements 19 bank right. They carry the ridge tread.

Das sich an den Ausbaubögen 20 abstützende Schreitwerk 10 bis 15 besteht aus dem mit den Schienen 16 fest verbundenen Kästen 11, an denen sich beiderseits die Hubzylinder 13 mit den Kolben 14 befinden, welche Platten 15 tragen, auf denen die Schienen 12 gleiten können. Die Schienen 12 sind mit den Schienen 16 oder dem Kasten 10 mittels hydraulischer Zylinder verbunden und so relativ zueinander verschiebbar. (In Fig. 1 liegen alle Schienen am Streckenbogen an.) Werden die Schienen 12 unter die Streckenbögen gepreßt., so geben über eingestellte Überdruckventile die Stempel 7 nach und die Schienen 16 lösen sih ab. In diesem Zustande kann der Kasten 10 unter Abstützung an den Schienen 12 vorgeschoben werden und mit ihm, da auch die Fußschreitwerke gleichzeitig tätig sind, das ganze System einshließlich der Antriebstation .gerückt werden. Danach werden die Stempel 7 höher aufgelastet und über ein eingestelltes Überdruckventil die Kolben 14 heruntergedrückt, bis alle 4 Schienen sich am Tragen der Ausbaubögen beteiligen. Die Schienen 12 gleiten über die Platten 15, und da diese Platten untereinander unabhängigigLten auch wellig gebogene Schienen darüber und können sich auch den unterschiedlichen Lagen der Ausbaubögen anpassen. Durch die Stempel 7 können übernormale Höhenabweichungen der Ausbaubögen überwunden werden. Die einzelnen, die Hubwerke 13,14,15 enthaltenden Kästen 11 sind lösbar mit dem Kasten 10 verbunden.The walking mechanism 10 to 15 supported on the extension arches 20 consists of the boxes 11 firmly connected to the rails 16, on which the lifting cylinders 13 with the pistons 14 are located on both sides, which carry plates 15 on which the rails 12 can slide. The rails 12 are connected to the rails 16 or the box 10 by means of hydraulic cylinders and are thus displaceable relative to one another. (In Fig. 1, all rails are in contact with the bend of the route.) If the rails 12 are pressed under the bends of the route, the punches 7 yield via the pressure relief valves set and the rails 16 become detached. In this state, the box 10 can be pushed forwards with support on the rails 12 and, since the footsteps are also active at the same time, the entire system including the drive station can be moved with it. Then the stamps 7 are loaded higher and the pistons 14 are pressed down via an adjusted pressure relief valve until all 4 rails take part in carrying the expansion arches. The rails 12 slide over the plates 15, and there these plates one below the other Also, wavy curved rails are independent and can move also adapt to the different positions of the extension arches. Above normal height deviations of the extension arches can be overcome by the stamp 7. The individual boxes 11 containing the hoists 13, 14, 15 are detachably connected to the box 10.
