Definitions

  • the invention relates to a partial cutting machine for cutting an arcuate section cross section in the underground mining and tunnel construction with cutting rollers that can be moved relative to the machine frame.
  • Seam or mining sections in underground mining are preferably excavated with an arcuate section, since the arch extension is best suited to absorb the high rock pressure or the cross-sectional narrowing (convergence) caused by it.
  • the aim is to expose the extension side parts at an angle, i.e. H. can be tilted more easily to the middle of the cross-section.
  • a so-called overcut of the profile can practically not be avoided with partial boom cutting machines, i.e. the cross-section of the route is usually not cut to the exact profile and too large, so that the route extension cannot be placed, or at least not continuously, flush against the mountain range and it is necessary to backfill the extension with mining mortar.
  • boom section cutting machine Another disadvantage of the boom section cutting machine is that because of the length of the cutting boom required to cover the entire cross-section of the boom, as well as the design-related arrangement of the lifting and swiveling cylinders at the machine end of the cutting boom and the resulting unfavorable lever ratios, only comparatively low contact forces are exerted on the Cutting head can be applied.
  • Boom part-cutting machines can therefore only be equipped with so-called shaft chisels. These chisels, which essentially scratch the mountains, only have an insufficient tool life in solid, abrasive bedrock and also unsatisfactory cutting performance.
  • roller chisels which are also suitable for loosening very hard rock due to their mode of operation, requires considerably higher pressure forces, which cannot be applied to boom section cutters, so that the area of application of these machines is severely restricted.
  • the object of the present invention is the development of a partial cutting machine which allows a precise cutting of an arcuate section profile without additional aids and which also to increase the propulsive power or for use, for. B. can be equipped in hard rock with roller chisels.
  • the upper and lower rollers are thus positively guided along predetermined movement paths and only perform simple, flat movements.
  • the extension to be brought in can be placed flush against the mountains. Additional backfill work is not necessary.
  • the bottom roller can be guided along a straight guide path that runs normally to the machine longitudinal axis.
  • This simple linear movement has the advantage over a possible pivoting movement about a vertical axis that the working face also runs straight in the area of the lower bench and the lower roller z. B. in the middle of the cross section does not have too large an advance compared to the top roller.
  • the drive for the transverse displacement of the lower roller is advantageously carried out by hydraulic cylinders which are arranged in the region of the guideway and directly attack behind the cutting roller.
  • hydraulic cylinders which are arranged in the region of the guideway and directly attack behind the cutting roller.
  • the top roller can also be equipped with roller chisels because of the relatively short required support arm length and thus a short lever length effective for power transmission, so that the part-cutting machine according to the invention can also be used in hard, abrasive rock or the cutting performance can be significantly improved compared to the known part-cutting machines .
  • the machine itself is comparatively small and light.
  • the high forces to be exerted on the cutting tools cannot be absorbed by the dead weight of the machine, as is the case with the boom section cutters, they must rather be derived in a manner known per se via support cylinders into the mountains, this introduction of force expediently via a preliminary expansion, e.g. B. knife shield, takes place, since then the introduction of the final expansion parallel to the tunneling is possible.
  • the bracing system can be divided into two, whereby each subsystem can be braced or relieved independently of the second.
  • Intermediate cylinders acting in the longitudinal direction of the line can then be used to move the machine in a manner known per se in accordance with the progress of the line advance.
  • the usual articulated connections are also provided, so that the machine can follow predetermined changes in inclination and direction of the route to be driven.
  • the partial cutting machine according to the invention also has the advantage that after dismantling the support arm with the top roller and possibly partial disassembly of the upper machine body or the bracing system, the machine can be used to cut a low door frame profile, so that if necessary the machine is also suitable for cutting the subsequent roughening in the driving sequence after the production of a seam section.
  • FIGS. 1 to 3 show a partial cutting machine 1 according to the invention with an upper roller 2 designed as a front roller and a lower roller 3 designed as a two-part cross-cutting roller.
  • Upper roller 2 and the roller bodies 8 of the lower roller 3 are the roller bodies 8 both on the circumference and on the front end face on the butt side additionally equipped with chisels in the outer area 27 of the rear end face.
  • the upper roller 2 is pivotally mounted on a support arm 4 on the inner machine body about an axis of rotation 6 parallel to the longitudinal axis of the machine and, during the pivoting movement, cuts the upper bench 10 of the face 22 with the circular ridge profile 11, which tangentially into the side profile 18 of the cross section cut by the lower roller 3 transforms.
  • the lower roll 3 which cuts the lower bench 12 with the side profile 18, is transversely displaced by means of a slide 7 along a straight guide track 5, which runs parallel to the track base 17 and runs normally to the machine longitudinal axis.
  • Any other suitable drive, e.g. B. a chain can be used.
  • the roller bodies 8 of the lower roller 3 are shaped like a truncated cone, the cone angles and the angle of inclination of the axes of rotation 13 against the track base 17 being coordinated such that on the one hand the lower cone surface line 16 of the roller bodies 8 run parallel to the track base 17, and on the other hand the end faces 9 with the track base 17 include the angle of inclination provided for the side profile 18 of the cross section.
  • the top roller 2 and bottom roller 3 are driven by separate drives 20 and 21, respectively.
  • the part-cutting machine is hydraulically clamped in the route in a manner known per se.
  • the machine is advanced in the direction of advance via hydraulic cylinders 25 which are arranged between the front and rear machine parts. With the exception of position corrections, the rollers do not perform any swiveling or sliding movement while the machine is being fed or when the rollers are cut into the face.
  • articulated connections between the front and rear machine frames about a vertical and transverse axis are provided in the usual way.
  • the lower roller 3 via a cylinder 25 can be raised compared to the front machine housing.
