Definitions
- the invention relates to a Butleruxnvor- driving machine with a rotatably mounted about an axis of rotation extending in the direction of advancing ff drilling head for hard rock and downstream mining tools to achieve a widened in the sole area sole.
- DE-AS 1260412 has disclosed an embodiment in which additional tools are arranged at a distance from the longitudinal axis of the machine in the direction of advancement behind the drill head in the lower region of the tunnel boring head, which can work off the material left standing by the drill head.
- the axes of the additional drilling tools are aligned parallel to the machine longitudinal axis and behind the two mining tools, a bucket-chain conveyor is provided, which receives the material.
- appropriately adapted mining tools are required and due to the direction of rotation of the additional tools results in a relatively difficult break-in towards the working face, the sole widening is limited accordingly.
- a support structure which defines a free space in the lower area, as in a portal, wherein the device shown can be mounted directly behind a drill head, so that an expansion in the tunnel or in the track can be set without it requires interim safeguards.
- the supporting structure requires additional space in the tunnel and can hinder the expansion.
- the invention now aims at providing a full-section track driving machine which is particularly suitable for the extraction of hard rock, with which initially a circular lug profile can be cut, whereby an almost flat sole is to be achieved without reducing the overall propulsion power.
- the training should be designed to be sufficiently compact in order to hinder the development of the line as little as possible, and be designed so that a sufficient propulsive power is ensured even with the downstream mining tools with material of high cube compressive strength or hard rock.
- the training according to the invention consists essentially in the fact that the downstream mining tools on the jacket and possibly. the end faces of transversely to the axis of rotation of the drill head rotatably mounted rollers are arranged.
- the training is thus made so that the mining tools are designed as a chisel.
- the training is advantageously made so that outside the bank longitudinal median plane two rollers are rotatably mounted, the axial length between 50 and 75 %, preferably 60 to 70%, of the radius of the drill head, wherein preferably the downstream roller bits are mounted on the jacket of the rollers with the axis of rotation of the rollers substantially parallel axes of rotation.
- Such a dimensioning of the rollers and such an arrangement of the axis of rotation of the roller chisel allows the respective dimensioning or the respective distances to be selected such that adapted to the cube compressive strength of the respective material to be degraded a correspondingly optimized overall propulsion performance can be achieved.
- the training is made so that the axial distances of the roller bits arranged distributed on the shell amount to 75 to 100% of the radial distances of the roller bits of the drill head. In this way, the same cutting parameters as in the discs of the rotatable main drill bit can be maintained.
- the material cut by the discs of the rollers can be picked up by broaching tools which also become effective in connection with the rotatably mounted drill head itself.
- the design is advantageously such that the rollers are drivable for rotation from the sole to the working face upwards, wherein preferably the drill head and / or a carrier coupled to the drill head have broaching tools, in particular chutes and Bear or buckets for receiving degraded material, which are movable via a discharge point on a discharge device.
- the broaching tools of the drill head can hereby be formed by fixed chutes in the drill head.
- Connected to the drill head can be equipped with folding blades a rotating carrier, which in each case at a transfer point or Abschstelle on a discharge device, the recorded material in turn drop onto the conveyor belt.
- a particular shape of the sole support is particularly advantageous, the training is advantageously made so that a slide-shaped sole support in the vertical longitudinal center plane of the tunneling machine is arranged, which extends from an end facing the working face to behind the projection of the axis of rotation of the rollers on the sole.
- a slide-shaped or runner-shaped support can correspond in contour to the outline shape of the rotatably mounted drill head and therefore rest stably on the sole over a relatively large area, the sole widening being slightly higher than the tangent to such a runner-shaped or slide-shaped sole support outside the sole support becomes effective.
- the support extends beyond the axis of rotation of the roller in order to be able to safely absorb reaction forces.
- Fig.l 1 with a drill head for hard rock is called, which rotatably mounted mining tools or disk tools 2 carries.
- the discs are rotatably mounted here about essentially radial axes.
- a part of the laterally projecting rollers 3 and 4 can be seen, which in turn carry mining tools or disc tools 5.
- the rollers 3, 4, the Sohlenverbreiterung is marrämt or degraded.
- rollers 3 and 4 and arranged on these rollers Diskenwerkmaschinee 5 are again visible.
- the distance a adjacent disk tools on the shell of the rollers 3 and 4 is chosen in accordance with the radial distances of the discs 2 of the drill head 1 in order to optimize the cutting performance.
- the rotation axis of the drill head is designated by 6 in FIG. 2, and it is further possible to see the runner-like sole support 7 which rests on the sole 8.
- the machine has lateral supports 9 and a Firstabstützung 10, which can be pressed against the already cut route or tunnel profile.
- the cylinders for the pressing of the supports 9 are indicated for example with 11.
- the discs 2 are visible, which are rotatably mounted on the drill head 1.
- the drill head 1 further carries shovel-like chutes 12, over which material is conveyed upwards on rotation of the drill head about the axis 6 and at a transfer point located at the top of a delivery means 13 enables the shedding of shredded material.
- the axes of rotation of the rollers 3 and 4 are denoted by 14, wherein the cut by the rotating chisels 5 envelope is indicated by 15.
- a carrier 16 connected to the drill head 1 carries folding blades 17, via which the material cut and picked up by the rollers rotating in the direction of the arrow 18 is in turn conveyed to a transfer point on the delivery means 13.
- the sole support in the form of a runner 7 extends below the axis of rotation 14 of the rollers 3 from one of the working face 19 facing the front end to a rear projection 20 of the axis 14, whereby a Tilting the tunneling machine can be effectively counteracted.
