Abstract

To comminute larger ground matter in driving shields equipped with a jaw crusher installation, which ground matter cannot be discharged through the suction line, it is proposed to arrange the crusher in such a way that the crusher jaws (12) open downwards and the distance of the jaw crusher (12) from the floor level (8) of the winning chamber or the floor level of the shield circumference is dimensioned in such a way that the floor level (8) of the winning chamber can be swept directly during the swivelling movement of the crushing jaws (12) and the large heap of debris collecting at the lowest point of the winning chamber can be seized directly and comminuted.

Description

Die Erfindung betrifft eine Schildvortriebseinrichtung, wie sie im Oberbegriff des Anspruchs 1 beschrieben ist.The invention relates to a shield driving device, as described in the preamble of claim 1.

Schildvortriebsmaschinen mit hydraulischer Abförderung des gelösten Haufwerks werden in der Regel in Lockerböden eingesetzt. Die Transportflüssigkeit dient dann zugleich der Stützung der Ortsbrust. Die Abbaukammer ist als geschlossene Druckkammer ausgebildet, in der die Abbauvorrichtung - z. B. ein Schneidrad - den Boden an der Ortsbrust abträgt, der dann auf die Sohle der Abbaukammer fällt und von dort durch einen Saugstutzen abgezogen wird. Größere Bodenbestandteile, die durch die Saugleitung nicht abförderbar waren, wurden von einem vorgeschalteten Rechen abgefangen und mußten von Hand durch Begehen der Abbaukammer entfernt werden, nachdem vorher aus der Kammer die Flüssigkeit durch Druckluft verdrängt war.Shield boring machines with hydraulic removal of the loosened pile are generally used in loose soils. The transport liquid then also serves to support the working face. The mining chamber is designed as a closed pressure chamber in which the mining device - for. B. a cutting wheel - removes the ground from the working face, which then falls on the bottom of the excavation chamber and is removed from there through a suction nozzle. Larger soil components that could not be removed through the suction line were intercepted by an upstream rake and had to be removed by hand by walking into the extraction chamber after the liquid had previously been displaced from the chamber by compressed air.

Zur Behandlung der unbehandelt nich abförderbaren Bodenbestandteile wurde auch bereits - beispielsweise nach der DE 32 38 953 - ein in der Abbaukammer angeordneter Brecher eingesetzt, dem ein rotierender Ringförderer die groben Bestandteile, die er von der Kammersohle aufnimmt, über einen Aufgabetrichter zur Zerkleinerung zuführt. Das zerkleinerte Brechgut fällt in der Kammer nach unten vor einen Rechen und kann vor dort durch den Saugstutzen abgefördert werden. Zu groß gebliebenes Brechgut wird erneut vom Ringförderer in den Brechkreislauf eingebracht.For the treatment of the soil components that cannot be removed untreated, a crusher arranged in the mining chamber has already been used - for example according to DE 32 38 953 - to which a rotating ring conveyor feeds the coarse components which it picks up from the chamber sole via a feed hopper for comminution. The shredded crushed material falls down in front of a rake in the chamber and can be removed through the suction nozzle. If the crushed material has remained too large, it is fed into the crushing circuit again by the ring conveyor.

Nachteilig an dieser bekannten Brecheranordnung ist der hohe mechanische und energetische Aufwand in der Abbaukammer für den Transport des Brechgutes zum Brecher und die hohe Anfälligkeit der vor Ort eingebauten Mechanik.Disadvantages of this known crusher arrangement are the high mechanical and energy expenditure in the excavation chamber for the transport of the crushed material to the crusher and the high susceptibility of the mechanics installed on site.

Aufgabe der Erfindung war es, eine Brecheranordnung zu entwickeln, die keine besondere Transporteinrichtung zur Zuförderung des Brechgutes benötigt und damit wesentlich wirtschaftlicher wird.The object of the invention was to develop a crusher arrangement which does not require any special transport device for feeding the material to be crushed and is therefore much more economical.

Die Aufgabe wird durch einen Schild gelöst wie er im kennzeichnenden Teil des Anspruchs 1 beschrieben ist. Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 7 beschrieben.The object is achieved by a sign as described in the characterizing part of claim 1. Embodiments of the invention are described in claims 2 to 7.

Die erfindungsgemäße Anordnung des Brechers im unteren Schildbereich unmittelbar über der Schildsohle und im Absaugbereich macht einen Transport des Brechgutes überflüssig. Die Brecharme greifen direkt das vor der Absaugöffnung zurückbleibende nicht abgeförderte Material und zerkleinern es solange, bis es durch den dem Saugstutzen vorgeschalteten Rechen bzw. durch die Öffnung des Saugstutzens hindurch geht.The arrangement of the crusher according to the invention in the lower shield area directly above the shield sole and in the suction area makes transport of the material to be crushed unnecessary. The crushing arms directly grasp the material that has not been removed from the suction opening and shred it until it passes through the rake upstream of the suction nozzle or through the opening of the suction nozzle.

Aus tunnelbautechnischen Gründen ist es zweckmäßig, die Abbaukammer kurz und den Saugstutzen soweit wie möglich in der Kammer nach vorn an die Ortsbrust heranzuführen. In einer Ausgestaltung der Erfindung nach Anspruch 2 wird der Saugstutzen daher bis in den Gerätebereich des Brechers geführt. Er muß - damit der Brecher in Aktion treten kann - aus dem Arbeitsbereich des Brechers herausfahrbar ausgebildet werden.For reasons relating to tunnel construction, it is expedient to bring the extraction chamber briefly and the suction nozzle as far forward as possible in the chamber to the face. In one embodiment of the invention according to claim 2, the suction nozzle is therefore guided into the device area of the crusher. In order for the crusher to be able to take action, it must be designed so that it can be moved out of the working area of the crusher.

Wird die Schwenkachse der Brechbacken des Backenbrechers entsprechend den Ansprüchen 3 oder 4 in der vertikalen Ebene durch die Schildachse nach vorn oder nach rückwärts gekippt, so entstehen durch die Schrägstellung unter bzw. hinter dem Brecher in radialen Schnitten dreieckige, sich rückwärtig zur Einmündung der Förderleitung erweiternde Räume, in die ein wahlweise teleskopierbarer Saugstutzen der Förderleitung unbeeinträchtigt von der Schwenkbewegung der Brechbacken nach vorn einführbar ist. Außerdam kann - ohne zusätzliche Baulänge ein Klassierrechen hinter dem Backenbrecher angeordnet werden.
Maßnahmen nach den Ansprüchen 6 und 7 sollen verhindern, daß sich Haufwerksteile zwischen Brechbacken und Schildsohle bzw. Klassierrechen einklemmen können.
Die Erfindung wird anhand der Figuren 1 - 5 erläutert. Es zeigen:

If the pivot axis of the jaws of the jaw crusher is tilted forwards or backwards in the vertical plane by the shield axis in accordance with claims 3 or 4, the oblique position below or behind the crusher results in triangular radial sections that expand towards the mouth of the delivery line Spaces into which an optionally telescopic suction nozzle of the delivery line can be introduced to the front unimpeded by the swiveling movement of the crushing jaws. In addition, a classifying rake can be arranged behind the jaw crusher without additional length.
Measures according to claims 6 and 7 are intended to prevent piling parts from getting caught between the crushing jaws and the shield sole or classifying rake.
The invention is explained with reference to FIGS. 1-5. Show it:

In einem Schild 1 mit einer durch eine Druckwand 3 rückwärtig geschlossenen Abbaukammer 2 wird der Boden an der Ortsbrust 4 durch eine Abbauvorrichtung 5 gelöst. Die Abbaukammer ist mindestens auf einen Teil ihrer Höhe mit unter Druck stehender Flüssigkeit 6 gefüllt. Das gelöste Haufwerk 7 fällt in der Flüssigkeit nach unten und sammelt sich im Bereich der Sohle 8 der Abbaukammer 2 und wird von dort mit Hilfe des Saugstutzens 9 kontinuierlich mit der eingepumpten Flüssigkeit 6 abgefördert.In a shield 1 with a mining chamber 2 closed at the rear by a pressure wall 3, the floor on the working face 4 is released by a mining device 5. The mining chamber is filled at least to a part of its height with liquid 6 under pressure. The dissolved heap 7 falls down in the liquid and collects in the area of the bottom 8 of the mining chamber 2 and is continuously conveyed from there with the pumped-in liquid 6 with the aid of the suction nozzle 9.

Bodenbestandteile 10, die größere Abmessungen aufweisen als sie mit dem Saugstutzen 9 aufnehmbar sind, werden von den die Sohle 8 der Abbaukammer 2 überstreichenden Brecherbacken 12 eines im unteren Bereich der Abbaukammer unterhalb der Antriebswelle 16 der Abbauvorrichtung 5 angeordneten Brechers 11 erfaßt und solange zerkleinert, bis sie absaugbar sind. Bei dem dargestellten Beispiel eines Saugstutzens wurde auf einen dem Stutzen vorgeschalteten Rechen verzichtet. Die Klassierung des gelösten Haufwerks erfolgt durch einen in der Ansaugöffnung 13 mittig angeordneten Gitterstab 14, der ausreicht, um zu große, nicht förderbare Bodenbestandteile 10 aus der Förderleitung 15 fernzuhalten. Im Ausführungsbeispiel nach Fig. 1 ist unter dem Backenbrecher auf der Schildsohle ein die Schwenkbewegung der Brechbacken in geringem Abstand umhüllendes Leitblech 17 angeordnet.Soil components 10, which have larger dimensions than can be accommodated with the suction nozzle 9, are grasped by the crusher jaws 12, which sweep over the sole 8 of the mining chamber 2, of a crusher 11 arranged in the lower region of the mining chamber below the drive shaft 16 of the mining device 5 and crushed until they are extractable. In the illustrated example of a suction nozzle, a rake upstream of the nozzle was dispensed with. The loosened aggregate is classified by a lattice bar 14 arranged centrally in the suction opening 13, which is sufficient to keep soil components 10 which are too large and cannot be conveyed away from the delivery line 15. In the exemplary embodiment according to FIG. 1, a baffle plate 17 which encloses the pivoting movement of the crushing jaws at a short distance is arranged under the jaw crusher on the shield sole.

Einen Backenbrecher 18 nach Anspruch 3 mit nach vorn gekippter Schwenkachse 20 der Brechbacken 19 zeigt Fig. 4. Bei einer Schwenkbewegung der Brechbacken 19 streicht die vordere Kante 21 dicht über der Sohle des Mantels des Schildes 1 hin, während die hintere Kante 22 sich mit größerem Abstand zur Sohle bewegt. Die die Schwenkbewegung der Brechbacken 19 umhüllende zylindrische Fläche 24, der Mantel des Schildes 1 und die Druckwand 3 umschließen einen sphärischen, in radialen Schnitten dreieckigen Raum 23, der von der Schwenkbewegung der Brechbacken 19 nicht getroffen wird. In diesem Raum 23 kann ein Klassierrechen 25 vor der Einmündung der Förderleitung 15 zum Abfördern des hereingewonnenen Haufwerks angeordnet sein. Die Stäbe des Klassierrechens 25 können einen Verlauf etwa parallel zur Schwenkbewegung der Brechbacken 19 aufweisen, so daß entsprechend auf den Brechbacken angeordnete Zähne vor und/oder in den Zwischenräumen zwischen den Stäben entlangstreichen können. In dem Raum 23 kann auch ein wahlweise teleskopierbar ausgebildeter Saugstutzen 19 der Förderleitung 15 außerhalb des Schwenkbereichs der Brechbacken 19 in die Abbaukammer 2 vorgeschoben werden.A jaw crusher 18 according to claim 3 with the pivot axis 20 of the crushing jaws 19 tilted forward is shown in FIG Distance to the sole moves. The cylindrical surface 24 enveloping the pivoting movement of the crushing jaws 19, the jacket of the shield 1 and the pressure wall 3 enclose a spherical space 23 which is triangular in radial sections and which is not hit by the pivoting movement of the crushing jaws 19. A classifying rake 25 can be arranged in this space 23 in front of the confluence of the conveying line 15 for conveying away the accumulated material. The bars of the classifying rake 25 can have a course approximately parallel to the pivoting movement of the crushing jaws 19, so that teeth arranged on the crushing jaws can sweep in front of and / or in the spaces between the bars. In the space 23, an optionally telescopic suction nozzle 19 of the delivery line 15 can be advanced into the extraction chamber 2 outside the swiveling range of the crushing jaws 19.

Einen Backenbrecher 27 nach Anspruch 4 mit nach rückwärts gekippter Schwenkachse 29 der Brechbacken 28 zeigt Fig. 5. Bei einer Schwenkbewegung der Brechbacken 28 streicht die rückwärtige Kante 31 dicht über die Sohle des Mantels des Schildes 1 hin, während die vordere Kante 30 sich mit größerem Abstand zur Sohle bewegt. Die die Schwenkbewegung der Brechbacken 28 rückwärtig begrenzende Ebene 33, die Druckwand 3 und der Mantel des Schildes 1 umschließen einen in radialen Schnitten dreieckigen Raum 32, der von der Schwenkbewegung der Brechbacken 28 nicht getroffen wird. In diesem Raum 32 kann ein Klassierrechen 34 vor der Einmündung der Förderleitung 15 zum Abfördern des hereingewonnenen Bodens angeordnet sein. In diesen Raum 32 kann auch ein wahlweise teleskopierbar ausgebildeter Saugstutzen 19 der Förderleitung 15 außerhalb des Schwenkbereichs der Brechbacken 28 in die Abbaukammer 2 vorgeschoben werden.FIG. 5 shows a jaw crusher 27 according to claim 4 with the pivot axis 29 of the crushing jaws tilted backwards. When the crushing jaws 28 pivot, the rear edge 31 brushes closely over the sole of the jacket of the shield 1, while the front edge 30 is larger Distance to the sole moves. The plane 33 which limits the pivoting movement of the crushing jaws 28 to the rear, the pressure wall 3 and the jacket of the shield 1 enclose a space 32 which is triangular in radial sections and which is not hit by the pivoting movement of the crushing jaws 28. A classifying rake 34 can be arranged in this space 32 in front of the confluence of the conveying line 15 for conveying away the soil obtained. In this space 32, an optionally telescopic suction nozzle 19 of the delivery line 15 can be advanced into the removal chamber 2 outside the swiveling range of the crushing jaws 28.
