Description
Einrichtung zum Rücken des Strebförderers Die Erfindung betrifft eine Einrichtung zum Rücken des Strebförderers, der in dem portalartigen Raum zwischen den beiden Stempeln der Stempelrahmen für den Untertageabb,au mit mechanisch rückbarem Stahlausbau ,angeordnet ist.Device for backing the face conveyor The invention relates to a Device to the back of the face conveyor, which is in the portal-like space between the two stamps of the stamp frame for underground demolition, au with mechanically relocatable Steel expansion, is arranged.
Es ist bereits ein mechanisch rückbarer Stahlausbau für den Untertageabbau bekannt, bei dem. zwischen den beiden Stempeln der Stempelrahmen ein portalartiger Raum gebildet ist. Hierbei sind aber die Strebförderer außerhalb dieses Raumes angeordnet und mit den Füßen der Stempel verbunden, so daß sie nur mit diesen zusammengerückt werden können. Es ist ferner die Benutzung von Seilzügen zum Rücken vonArbeitsgeräten im ;Unter, tageabbau bekannt. Hierbei handelt !es sich aber um das Rücken der Gerüste für Schrämketten, die auch das Wegförde.rn des ge-,vonnenen Gutes übernehmen, ohne Verbindung mit rück .baren Stahlausbauen.It is already a mechanically movable steel structure for underground mining known to the. between the two stamps of the stamp frame a portal-like one Space is formed. Here, however, the face conveyors are arranged outside of this space and connected to the feet of the pistons, so that they only come together with these can be. It is also the use of cables to back work equipment im; under, day degradation known. But this is the back of the scaffolding for cutting chains, which also take over the conveying away of the goods received, without Connection with retractable steel extensions.
Demgegenüber besteht das kennzeichnende Merkmal der Einrichtung darin, daß an den voreilenden Nebenstempeln der Stempelrahmen und an der vorderen Seite des Strebfördenerträgers. zwischen dem Abbaustoß und dem Strebförderer Seilrollen angeordnet sind, über die ein in Zickzacklinie geführtes Seil gelegt ist, das zu einem Seilhaspel geführt ist, derart, daß der Strebförderer in einem Zuge jeweilig um eine volle Varhiehbreite nachgerückt werden kann, sowie daß zwischen der hinteren Seite des Strebförderers und den Hauptstempeln der Stempelrahmen Distanzseilstränge angeordnet sind, die den Strebförderer in seiner Endstellung in gleichmäßigem Abstande von den Stempeln halten..In contrast, the distinguishing feature of the facility is that on the leading secondary stamps of the stamp frame and on the front side of the face carrier. pulleys between the working face and the face conveyor are arranged, over which a zigzag line is laid, the to a cable reel is guided in such a way that the face conveyor respectively in one go can be advanced by a full Varhiehbreite, as well as that between the rear Side of the face conveyor and the main rams of the ram frame spacer cable strands are arranged that the face conveyor in its end position at equal intervals keep off the stamps ..
Auf der Zeichnung ist die Einrichtung nach der Erfindung beispielsweise dargestellt. Abb. i zeigt die Stempelrahmen und den Strebförderer mit der Rückeinrichtung in Draufsicht.In the drawing, the device according to the invention is for example shown. Fig. I shows the stamp frame and the face conveyor with the rear device in plan view.
Abb. z und 3 zeigen dasselbe im senkrechten Querschnitt vor und nach der Rückumg des Strebförderers.Fig. Z and 3 show the same in vertical cross section before and after the back of the face conveyor.
Der Stahlausbau besteht aus einzelnen für sich rückbaren Stempelrahmen A. jeder dieser Stempelrahmen besteht aus dem Hauptstempel i, dem Nebems.tempel z und dem Dekkenträger 3. Die Stempel i rund z sind so weit voneinander :entfernt, daß zwischen ihnen ein portalartiger freier Raum für den StrebföTderer B und für die Durchfahrt eines Gewinnungs- und Ladegerätes vorhanden ist. Erfindungsgemäß sind zum Rücken des Strebförderers B an den Nebenstempeln 2 der Stempelrahmen A nach dem Portal zu und ebenfalls an der den Nebenstempeln 2 zugewandten Seite des Streb.fördererträgers B Seilrollen 12 und 13 angeordnet. Über die Rollen ist im Zickzack -ein Seil 14 gelegt, das zu einem Seilhaspel 15 führt. Zwischen 3,°n Hauptstempeln i der StempelrahmenA und der diesen zugewandten Seite des StrebfördererträgersB sind Distanzseilstränge i6 angeordnet, die zur Begrenzung der Rückbi,-,megung des Strebförderers innerhalb des Raumes zwischen den Stempeln der Stempelrahmen dienen. In Abb. i ist die Lage des- Strebförderers und der Teile der Rückeinrichtung nach erfolgter Rückumg in durchbrochenen Linien dargestellt. In Abb. i und in Abb. 3 sind die :entsprechenden Teile mit B', i3', 14', i 6' bezeichnet.The steel structure consists of individual stamp frames A. Each of these stamp frames consists of the main stamp i, the Nebems.tempel z and the cover carrier 3. The stamps i around z are so far apart that between them a portal-like free space for the StrebföTderer B and for the passage of an extraction and loading device is available. According to the invention, to the rear of the face conveyor B on the secondary rams 2, the ram frame A is arranged towards the portal and also on the side of the face conveyor carrier B facing the secondary rams 2, rope pulleys 12 and 13 . A rope 14, which leads to a rope reel 15, is laid in a zigzag over the rollers. Between 3, ° n main punches i of the punch frame A and the side of the face conveyor carrier B facing them, spacer cable strands i6 are arranged, which serve to limit the backward movement of the face conveyor within the space between the punches of the punch frame. In Fig. I, the position of the face conveyor and the parts of the return device after the return is shown in broken lines. In Fig. I and in Fig. 3 the: corresponding parts are denoted by B ', i3', 14 ', i 6'.
