- a generic track boring machine in which the pre-drill is connected via a central drive shaft connected to the drill head body, which on the one hand limits the swivel angle of the tool carriers which can be pivoted radially between the point of attack in the pre-drilled hole and the track joints, and which on the other hand, very high forces must be transmitted in connection with a pre-drill with a large cross section.
- the diameter of the pilot drill must be such that the roller tools of the swiveling tool carrier can take advantage of the undercutting to intervene in the mountains between the drive shaft and the borehole wall.
- Such a large-sized pre-drilling head requires the transmission of a very high torque and requires very high pressure forces, which in turn represent a high uneconomical energy expenditure.
- the drive shaft must absorb the transverse forces caused by the large pre-drilling head.
- constructional difficulties continue to arise in that it is difficult to displace the thrust piston gears required for the pivotable tool carriers.
- Deviating from such a design of a track boring machine, another machine for driving track tunnels or the like with a rotationally drivable working head is known from the unpublished patent application P 40 15 462.9, to which, for example, four pivotable roller boring tool arms are articulated. Since such a device works without a pilot hole, but at the same time the roller drilling tools are to work according to the undercut principle, a tool arm is provided which can be pivoted almost centrally to the working head in order to create a suitable cavity for the engagement of the other tool carriers.
- the invention is based on the object of specifying a track boring machine of the generic type which enables a reduction in the energy expenditure in the production of the pilot hole, the stresses resulting from the operating torques and transverse forces and the wear on the boring machine.

- the frame construction articulated at right angles to the swiveling tool carriers on the drill head base body makes it possible to create sufficient space for the push piston mechanisms of the swiveling tool carriers.
- the design of the pilot drill as a ring drill namely the formation of two tool arms articulated on a crossbar, makes it possible to drill an annular cavity which, due to the small area to be machined, requires less torque and lower pressing forces.
- the right-angled arrangement of the frame construction and the tool arms, which are articulated as pre-drills allow the pivoting angle to be increased for the pivotable tool carriers working according to the undercut principle.
- pivotable tool carriers each provided with at least one roller drilling tool, can intervene in the space between the tool arms designed as ring drills in the arrangement at right angles to the supporting structure, they are at the same time able, if the drill core does not break off automatically, to destroy it on its way back.
- the frame construction carrying the ring drill can be provided with further transverse reinforcements and can in this way take over the forces occurring on the ring drill without difficulty.
- the feed device for displacing the supporting structure in the longitudinal direction has feed cylinders integrated in the side supports.

Abstract
Description
Die Erfindung betrifft eine Streckenvortriebsmaschine zum Auffahren von untertägigen Strecken mit einem drehend antreibbaren Bohrkopfgrundkörper, mit einem am Bohrkopfgrundkörper angeordneten und mit diesem angetriebenen starren Vorbohrer sowie mit um Schwenkachsen am Bohrkopfgrundkörper angelenkten Werkzeugträgern mit mindestens einem nach dem Hinterschneidprinzip arbeitenden Rollenbohrwerkzeug, wobei die Werkzeugträger über Schubkolbengetriebe zumindest vom Angriffspunkt im Vorbohrloch bis zum Umriß des Streckenquerschnitts ausstellbar sind.The invention relates to a tunnel boring machine for driving underground routes with a rotatingly drivable drill head base body, with a rigid pre-drill arranged on the drill head base body and driven with it, and with tool carriers articulated about pivot axes on the drill head base body with at least one roller drilling tool working according to the undercutting principle, the tool carriers at least via thrust piston gears from the point of attack in the pilot hole to the outline of the cross-section.
Nach der DE-PS 31 40 707 ist eine gattungsgemäße Streckenvortriebsmaschine bekannt, bei welcher der Vorbohrer über eine zentrale mit dem Bohrkopfkörper verbundene Antriebswelle verbunden ist, die auf der einen Seite den Schwenkwinkel der radial zwischen Angriffspunkt im Vorbohrloch und den Streckenstößen verschwenkbaren Werkzeugträgern einschränkt und die andererseits in Verbindung mit einem im Querschnitt großen Vorbohrer sehr hohe Kräfte übertragen muß.According to DE-PS 31 40 707 a generic track boring machine is known, in which the pre-drill is connected via a central drive shaft connected to the drill head body, which on the one hand limits the swivel angle of the tool carriers which can be pivoted radially between the point of attack in the pre-drilled hole and the track joints, and which on the other hand, very high forces must be transmitted in connection with a pre-drill with a large cross section.
Der Vorbohrer muß im Durchmesser eine derartige Größe aufweisen, daß die Rollenwerkzeuge der schwenkbaren Werkzeugträger um die Vorteile des Hinterschneidens nutzen zu können, zwischen der Antriebswelle und der Bohrlochwandung ins Gebirge eingreifen können. Ein derartiger groß zu dimensionierender Vorbohrkopf macht die Übertragung eines sehr hohen Drehmomentes erforderlich und benötigt sehr hohe Andruckkräfte, die wiederum einen hohen unwirtschaftlichen Energieaufwand darstellen.The diameter of the pilot drill must be such that the roller tools of the swiveling tool carrier can take advantage of the undercutting to intervene in the mountains between the drive shaft and the borehole wall. Such a large-sized pre-drilling head requires the transmission of a very high torque and requires very high pressure forces, which in turn represent a high uneconomical energy expenditure.
Darüber hinaus muß die Antriebswelle, die durch den großen Vorbohrkopf auftretenden Querkräfte aufnehmen. Bei der Verwendung einer starren, den Vorbohrer tragenden Welle treten weiterhin konstruktive Schwierigkeiten dahingehend auf, daß es schwierig ist, die für die schwenkbaren Werkzeugträger erforderlichen Schubkolbengetriebe zu verlagern.In addition, the drive shaft must absorb the transverse forces caused by the large pre-drilling head. When using a rigid shaft carrying the pilot drill, constructional difficulties continue to arise in that it is difficult to displace the thrust piston gears required for the pivotable tool carriers.
Abweichend von einer derartigen Ausführung einer Streckenvortriebsmaschine ist nach der nicht veröffentlichten Patentanmeldung P 40 15 462.9 eine weitere Maschine zum Vortreiben von Streckentunnel oder dergleichen mit einem drehend antreibbaren Arbeitskopf bekannt, an welchem beispielsweise vier verschwenkbare Rollenbohrwerkzeuge tragende Werkzeugarme angelenkt sind. Da eine derartige Einrichtung ohne Vorbohrloch arbeitet, gleichzeitig aber jedoch die Rollenbohrwerkzeuge nach dem Hinterschneidprinzip arbeiten sollen, ist ein Werkzeugarm vorgesehen, der nahezu zentral an dem Arbeitskopf angelenkt verschwenkbar ist, um für den Eingriff der übrigen Werkzeugträger eine geeignete Aushöhlung zu schaffen.Deviating from such a design of a track boring machine, another machine for driving track tunnels or the like with a rotationally drivable working head is known from the unpublished patent application P 40 15 462.9, to which, for example, four pivotable roller boring tool arms are articulated. Since such a device works without a pilot hole, but at the same time the roller drilling tools are to work according to the undercut principle, a tool arm is provided which can be pivoted almost centrally to the working head in order to create a suitable cavity for the engagement of the other tool carriers.
Dabei treten für einen außermittig am Arbeitskopf angelenkten einzelnen Werkzeugarm, der die Wirkung eines Vorbohrers erzielen soll, sehr große Kräfte auf, die einen erheblichen Verschleiß mit sich bringen. Darüber hinaus liegt ein wesentlicher Nachteil einer solchen Anordnung darin, daß ein kontinuierliches Arbeiten, nämlich das gleichzeitige Aushöhlen zum Hinterschneiden und das Hinterschneiden gleichzeitig nicht durchführbar ist.For a single tool arm articulated off-center on the working head, which is intended to achieve the effect of a pre-drill, very large forces occur which cause considerable wear. In addition, a major disadvantage of such an arrangement is that continuous working, namely concurrently hollowing out for undercutting and undercutting, cannot be carried out at the same time.
Der Erfindung liegt die Aufgabe zugrunde, eine Streckenvortriebsmaschine der gattungsgemäßen Art anzugeben, die eine Reduzierung des Energieaufwandes bei der Herstellung des Vorbohrloches, der Beanspruchungen aus den betriebsbedingt auftretenden Drehmomenten und Querkräften sowie des Verschleisses an der Vortriebsmaschine ermöglicht.The invention is based on the object of specifying a track boring machine of the generic type which enables a reduction in the energy expenditure in the production of the pilot hole, the stresses resulting from the operating torques and transverse forces and the wear on the boring machine.
Diese Aufgabe wird dadurch gelöst, daß der Vorbohrer als einen Bohrkern durch Schlitzen eines Ringhohlraumes hereingewinnender Ringbohrer ausgebildet ist, der aus zwei parallel zueinander und im Abstand zur zentralen Achse des Streckenhohlraums vorgesehenen, an Werkzeugarmen angeordneten Bohrwerkzeugen besteht und die Werkzeugarme an einem Querbalken einer eine Vorschubeinrichtung aufweisenden, am Bohrkopfgrundkörper angeordneten rahmenartigen Tragkonstruktion angelenkt sind, wobei die Seitenträger der rahmenartig ausgebildeten Tragkonstruktion gegenüber den Werkzeugträgern der Aufweitungswerkzeuge um 90° um die Längsachse verdreht am Bohrkopfgrundkörper angeordnet sind, und daß die Schubkolbengetriebe der Werkzeugträger von der rahmenartigen Tragkonstruktion umgriffen sind.This object is achieved in that the pilot drill is designed as a drill core by slitting an annular cavity, which consists of two drill tools arranged parallel to one another and at a distance from the central axis of the line cavity and arranged on tool arms and the tool arms on a crossbar of a feed device having, frame-like support structure arranged on the drill head base body are articulated, the side supports of the frame-like support structure being arranged rotated by 90 ° about the longitudinal axis relative to the tool supports of the widening tools on the drill head base body, and the thrust piston gears of the tool supports being encompassed by the frame-like support structure.
Die rechtwinklig zu den verschwenkbaren Werkzeugträgern am Bohrkopfgrundkörper angelenkte Rahmenkonstruktion gestattet die Möglichkeit, ausreichenden Platz für die Schubkolbengetriebe der verschwenkbaren Werkzeugträger zu schaffen.The frame construction articulated at right angles to the swiveling tool carriers on the drill head base body makes it possible to create sufficient space for the push piston mechanisms of the swiveling tool carriers.
Darüber hinaus ist durch die Ausbildung des Vorbohrers als Ringbohrer, und zwar durch die Ausbildung zweier an einen Querbalken angelenkter Werkzeugarme die Möglichkeit vorhanden, einen Ringhohlraum abzubohren, der durch die geringe zu bearbeitende Fläche ein geringeres Drehmoment und geringere Andruckkräfte erfordert. Weiterhin erlaubt die rechtwinklige Anordnung der Rahmenkonstruktion und der daran angelenkten als Vorbohrer ausgebildeten Werkzeugarme eine Vergrößerung des Verschwenkwinkels für die nach dem Hinterschneidprinzip arbeitenden verschwenkbaren Werkzeugträger.In addition, the design of the pilot drill as a ring drill, namely the formation of two tool arms articulated on a crossbar, makes it possible to drill an annular cavity which, due to the small area to be machined, requires less torque and lower pressing forces. Furthermore, the right-angled arrangement of the frame construction and the tool arms, which are articulated as pre-drills, allow the pivoting angle to be increased for the pivotable tool carriers working according to the undercut principle.
Da die mit mindestens einem Rollenbohrwerkzeug jeweils versehenen verschwenkbaren Werkzeugträger in der rechtwinklig versetzten Anordnung zur Tragkonstruktion in den Freiraum zwischen den als Ringbohrer ausgebildeten Werkzeugarmen eingreifen können, sind sie gleichzeitig in der Lage, sollte der Bohrkern nicht selbsttätig abbrechen, diesen auf ihrem Rückweg zu zerstören. Die den Ringbohrer tragende Rahmenkonstruktion kann mit weiteren Querverstärkungen versehen sein und kann auf diese Weise ohne Schwierigkeiten die am Ringbohrer auftretenden Kräfte übernehmen.Since the pivotable tool carriers, each provided with at least one roller drilling tool, can intervene in the space between the tool arms designed as ring drills in the arrangement at right angles to the supporting structure, they are at the same time able, if the drill core does not break off automatically, to destroy it on its way back. The frame construction carrying the ring drill can be provided with further transverse reinforcements and can in this way take over the forces occurring on the ring drill without difficulty.
Vorteilhafterweise weist die Vorschubeinrichtung zur Verschiebung der Tragkonstruktion in Längsrichtung in den Seitenträgern integrierte Vorschubzylinder auf.Advantageously, the feed device for displacing the supporting structure in the longitudinal direction has feed cylinders integrated in the side supports.
Die Steuerung des Vorbohrers bzw. der Vorschubeinrichtung ist unabhängig von der Steuerung der Schwenkarme.The control of the pre-drill or the feed device is independent of the control of the swivel arms.
Die Werkzeugarme, die den Ringbohrer bilden, können mit an auswechselbaren Werkzeughaltern angelenkten Rollenbohrwerkzeugen oder Hartmetallmeißeln versehen sein.The tool arms that form the ring drill can be provided with roller drilling tools or hard metal chisels articulated on interchangeable tool holders.
