The invention relates to a tunneling machine for driving routes or tunnels, both together

Driving machines belong there !! to form the state of the cutting roller in such a way that their Meißep ie the lateral surface of a Hen DoDDeliiegelstumpfe taper to de, roller ends.

However, when choosing the anchoring position, the operator is solely dependent on his sense of proportion or on his feeling; if he drives the tunneling machine too close to the site, the boom runs against the solid mineral of the face, and the cutting roller itself lies with its entire diameter in the mineral and runs firmly here. If, on the other hand, the tunneling machine is anchored too far from the face, the penetration depth of the cutting roller is too shallow and its smooth running, the strong vibrations of the machine body, is unsatisfactory ,

To solve this problem, the invention is based on of the tunneling machine explained at the beginning and suggests the swivel range of the boom in to be determined in both directions by a swiveling wheel starting from the support arm "longitudinal plane," its greatest dimension through the

is determined, whereby the angle «corresponds to the half pivoting angle of the boom starting from the longitudinal plane of the support arm, the dimension a corresponds to the distance between the cutting roller axis and the boom axis and D corresponds to the cutting roller diameter. i> en diameter must be driven into the face so that it can work with sufficient smoothness, and that it may be driven into the open face at most up to Vi of its diameter, since otherwise the boom would run against the remaining parts of the face, so With a given scraper roller diameter and a given distance between the cutting drum axis and the swivel axis, the limits of the boom swivel range can be determined with the aid of the two aforementioned equations. At the same time, however, the position of the tunneling machine m with respect to the face is determined in which the cutting roller can work the entire face in the yoifaesciiriebenen depth regardless of the respective support arm inclination. The operator can now lift the cutting roller with a high boom to the top of the road or lower it with a low boom to the bottom of the road and then advance the driving machine until the cutting roller runs against the face elongated boom always the required single-ring depth, i.e. depending on the pivoting shape of the boom, it is at least half the roller diameter and at most ² hours of the roller diameter.

In addition, with a tunneling machine designed in this way, the requirement that is repeatedly raised in civil engineering and mining, namely the exact adherence to the route profile, can be implemented particularly well.

It is also advisable to equip the tunneling machine with several abutments for these adjusting cylinders, to change the swivel range of the boom in relation to the longitudinal plane of the support arm if necessary can.

Appropriately, when one of the two cylinder cylinders is acted upon, the two spaces of the respective unloaded actuator cylinder with the return line connected and the pistons of both actuating cylinders blocked in the rest position of the boom malfunctions are avoided, and the boom of the two Stellzyliudern held rigidly in their respective operating position.

The tunneling machine 1 is equipped with a crawler chassis 3 supporting the machine frame 2. In addition, it has a 3 in front of the head of the landing gear

The loading shovel 4 are approximately two loading conveyor 8 running parallel to one another, the debris accumulating during the advance arranged at the rear end of the machine,

At the opposite end of the machine there is a support arm 12 that can be pivoted about a horizontal, axis 10 by means of that pressure cylinder 11, in the direction towards the town front of the loading section to be driven out, at the 4 upper edge of the horizontal loading bin pivot axis 10, geno £ t in an on. · to the machine frame / 2 "'mounted * console Ί5 which a' is pivotally vertical * axis 18 by means zv / eggs pressure cylinders 17, 18 the horizontal Oh ^c? iO of the support arm 12 and 4uch the vertical axis 16 of the console 15 lie in a common, vertical plane Eme cutting roller 13 forms the loosening tool of this tunneling machine 1 It rotates around an axis 20 parallel to the bottom of the route and at right angles to the route base and is held by a boom 21, which with its' i rear, fork-shaped end includes the front end of the support arm and with it through the to the support arm length Right-angled, horizontal axis 22 is articulated. Two approaches 23, 24 of the boom 21, one of which is above and the other below the plane running through the two horizontal axes 20, 22, are located on opposite support arm sides (Fig. 2) . An adjusting cylinder 26, 27 each engages with the head of its piston rod 23, both of which are pivotably connected to their cylinder housings at 29 and 30, respectively, with the support arm 12.
