Definitions

  • the present invention relates generally to hoisting machines which, for the implementation of the method of digging a gallery underground described in the French patent filed on December 4, 1969 under No 69 41839 and published under No 2,070,413 are specific to the precut of the roof of such a gallery, that is to say to the execution of a curved groove in the face of the latter.
  • Cutting machines of this type are for example described in the French patent filed on March 24, 1975 under No 75 09034 and published under No 2 305 583 and in the Italian patent filed on December 29, 1987 under No 23243A / 87 and published under No. 1 224 420.
  • the carriage comprises a base, by which it is engaged with the fixed guide, and a superstructure, on which is attached, according to various practical embodiments, the cutting head.
  • this arm is carried by a central box, which inadvertently obscures the axis of the gallery.
  • the present invention generally relates to a provision allowing a fixed guide cutting machine to adapt to any gallery profile.
  • a cutting machine of the kind comprising a fixed guide, which is in the form of a gantry, and a carriage, which, mounted movably on the fixed guide, carries a cutting head, this carriage comprising a base by which it engages with the fixed guide and a superstructure on which the cutting head is attached, this cutting machine being generally characterized in that, between the base of the carriage and its superstructure, intervene, jointly, on the one hand, extension means, adapted to allow a radial displacement of the cutting head relative to the fixed guide, and, on the other hand, angulation means, adapted to allow a tilting of this cutting head around an axis parallel to the axis of this fixed guide.
  • the cutting head can advantageously follow, within certain limits, any profile.
  • This curved groove 12 extends in practice from one edge to the other of the wall 13, or floor, of the gallery 10.
  • pre-vault ring 15 under the shelter of which the ground can then advantageously be scoured, and, preferably, the pre-vault thus established ring by ring is subsequently doubled by a definitive arch, not shown .
  • a cutting machine 16 is used for the execution of the curved groove 12.
  • the cutting machine 16 generally comprises, on the one hand, a fixed guide 17, which is in the form of a gantry, and, on the other hand, a carriage 18, which, movably mounted on the fixed guide 17, carries, along a generator, a cutting head 20.
  • the fixed guide 17 has, overall, a circular profile, and it extends over a little more than 180 °.
  • this fixed guide 17 can just as easily have any other profile and / or any other extension.
  • it is generally cylindrical.
  • Its axis A1 which is shown diagrammatically by its trace in FIG. 1, extends in the direction of elongation of the gallery 10.
  • the fixed guide 17 is carried by an infrastructure 21 suitable for allowing it to run parallel to its axis A1.
  • this infrastructure 21 may consist of two walking beams 22 arranged, each respectively, and parallel to one another, at the two ends of the fixed guide 17.
  • the infrastructure 21 also carries, laterally, along one side of the fixed guide 17, beyond the latter, and parallel to its axis A1, a conveyor 23 specific to the removal of spoil.
  • the carriage 18 comprises, in the embodiments shown, a base 25, by which it is engaged with the fixed guide 17, and a superstructure 26, on which the cutting head 20 is attached.
  • the base 25 itself comprises, on the one hand, a sole 28, by which it is effectively engaged, for example rolling, with the fixed guide 17, and, on the other part, a plate 29, which is pivotally mounted on the sole 28, about an axis A2 perpendicular to the axis A1 of the fixed guide 17, and on which is reported, according to arrangements described in more detail later, the cutting head 20.
  • the sole 28 extends on the upper surface of the fixed guide 17, by covering it transversely in a U shape.
  • this sole 28 extends to the lower surface of the fixed guide 17, while being suspended by returns 30 to the upper surface of the latter.
  • the axis A2 by which the plate 29 is articulated to this sole 28 extends on the upstream side of the fixed guide 17, that is to say on the side of the latter opposite the front of size 11, while, on the downstream side of the fixed guide 17, that is to say on the side of the size 11 front, there is a jack 32 between this plate 29 and this sole 28, making it possible to raise more obliquely or less the plate 29 with respect to the sole 28.
  • the body of the jack 32 is secured to the sole 28, while its piston rod is secured to the plate 29, while in practice being articulated thereto.
  • the superstructure 26 of the carriage 18 comprises, parallel to the axis A1 of the fixed guide 17, a slide 33 in which is mounted movably, slidingly, the cutting head 20, which allows penetration into the terrain of the cutting blade 34 thereof without displacement of the fixed guide 17, and therefore without displacement of the assembly of the cutting machine 16.
  • the cutting head 20 is of the usual constitution.
  • the extension means comprise, parallel to each other, two slides 35, which, staggered along the axis A1 of the fixed guide 17, being arranged one on the upstream side of this fixed guide 17 the other on the downstream side thereof, are each individually in sliding engagement with slides 36 provided for this purpose on the base 25 of the carriage 18, and, more specifically, on the plate 29 that this base 25 comprises.
  • each slide 35 there are provided, for each slide 35, two jacks 38, which, each respectively, are arranged on either side of such a slide 35.
  • the body 39 of these jacks 38 is integral with the plate 29 of the base 25 while their piston rod 40 is integral with the corresponding slide 35.
  • the angulation means of the cutting head 20 result from the fact that the superstructure 26 which carries it is pivotally mounted on the slides 35.
  • this superstructure 26 carries, in alignment with one another, two pins 41, which are each respectively arranged on the upstream side and on the downstream side of the fixed guide 17, and by which it is articulated to the slides 35, under the control of at least one jack 42.
  • a single jack 42 is provided, and it extends obliquely from one of the slides 35 to the superstructure 26, being for example articulated by its body 43 to this slide 35 and by its rod piston 44 at this superstructure 26.
  • the cutting head 20 can advantageously follow any profile, and, for example, one or the other of the two profiles 12I, 12II shown diagrammatically in broken lines in FIG. 1, while remaining tangent to such a profile.
  • the profile 12I is, in FIG. 1, a circular profile concentric with that of the fixed guide 17, while the profile 12II is a profile which, also concentric with that of the fixed guide 17 in its central part, departs laterally of the latter along two straight lines.
  • the extension means to which the cutting head 20 is subjected comprise, parallel to one another, at least two jacks 38 ', which, staggered longitudinally along the the axis A1 of the fixed guide 17, in the manner of the preceding slides 35, intervene jointly between the base 25 and the superstructure 26, and, more precisely, between the plate 29 of this base 25 and the superstructure 26.
  • the body 39 'of these jacks 38' is secured to the plate 29, while their piston rod 40 'is secured to the superstructure 26, while being articulated thereto.
  • each of these jacks 38 ' is paired with another jack 38'', which, separated from it along the fixed guide 17, is capable of being controlled independently.
  • FIG. 3 it is a cylinder 50 additional to the piston rod 51 from which the piston rod 40 ', 40' 'of one of the cylinders 38', 38 '' is articulated.
  • FIG. 5 it is a connecting rod 52, which, at one of its ends, is articulated to the superstructure 26, and which, at the other of its ends, is articulated to the rod of piston 40 ', 40' 'from one of the cylinders 38', 38 ''.
  • the axis A3 along which the tilting head 20 is tilted is merged either with the articulation axis intervening between the jack 50 and one of the jacks 38 ', 38' ', or with the articulation axis intervening between the superstructure 26 and the link 52.
  • the fixed guide used could for example be generally frustoconical.
  • extension and / or angulation means could include jacks.
