Definitions
- the present invention relates generally the cutting machines which, for the implementation of the process digging an underground gallery described in the patent French registered on December 4, 1969 under No 69 41839 and published under No. 2 070 413, are specific to the pre-cutting of the roof of such a gallery, that is to say the execution of a curved bleeding in the face of the latter.
- Cutting machines of this type are found by 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 engages with the fixed guide, and a superstructure, to which is reported, according to various practical methods of production, the cutting head.
- this arm is carried by a box central, which inadvertently obscures the axis of the gallery.
- the present invention generally has for object a provision allowing a cutting machine to fixed guide to adapt to any gallery profile.
- a machine of the type having a fixed guide, which is shaped gantry, and a carriage, which, movably mounted on the guide fixed, 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, suitable for allowing radial displacement of the cutting head with respect to the fixed guide, and, on the other part, means of angulation, suitable for allowing a tilting of this cutting head around a parallel axis to the axis of this fixed guide, so that the cutting head can follow any profile, while remaining tangent to this profile.
- the cutting head can, advantageously, follow, within certain limits, a profile any.
- This curved groove 12 extends in practice from one edge to the other of wall 13, or floor, of gallery 10.
- the cutting machine 16 comprises, overall, on the one hand, a fixed guide 17, which is in the form of gantry, and, on the other hand, a carriage 18, which, mounted mobile on the fixed guide 17, carries, according to a generator, a head of havage 20.
- the guide fixed 17 has, overall, a circular profile, and it spans just over 180 °.
- this fixed guide 17 can just as easily well have any other profile and / or any another extension.
- it is generally cylindrical.
- Its axis A1 which is shown diagrammatically by its trace on the Figure 1, extends in the direction of elongation of the gallery 10.
- the guide fixes 17 is carried by an infrastructure 21 suitable for enabling it the path parallel to its axis A1.
- this infrastructure 21 can consist of two beams walking 22 arranged, each respectively, and parallel to each other, at both ends of the guide fixed 17.
- the infrastructure 21 also carries, laterally, along on one side of the fixed guide 17, beyond it, and parallel to its axis A1, a conveyor 23 suitable for the removal of spoil.
- the carriage 18 comprises, in the forms embodiments shown, a base 25, by which it is in engagement with the fixed guide 17, and a superstructure 26, on which is added the cutting head 20.
- the base 25 comprises, itself, on the one hand, a sole 28, by which it is actually engaged, for example at bearing, with the fixed guide 17, and, on the other hand, 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 subsequently, the cutting head 20.
- the sole 28 extends to the upper surface of the fixed guide 17, by styling transversely in U this one.
- this sole 28 extends on the underside of the fixed guide 17, being suspended by 30 returns to the upper surface of it.
- the axis A2 by which the plate 29 is articulated to this sole 28 extends from the upstream side of the guide fixed 17, that is to say on the side thereof 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, it intervenes, between this plate 29 and this sole 28, a jack 32, making it possible to more or less obliquely lift the plate 29 relative to sole 28.
- the cylinder body 32 is integral with the sole 28, while its piston rod is integral with the plate 29, being in practice articulated to this one.
- the superstructure 26 of carriage 18 comprises, parallel to the axis A1 of the fixed guide 17, a slide 33 in which is mounted mobile, sliding, the cutting head 20, which allows the penetration into the ground of the cutting blade 34 thereof without displacement of the fixed guide 17, and therefore without displacement of the entire cutting machine 16.
- the cutting head 20 is of constitution usual.
- 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 side downstream of it, are each individually engaged in sliding with slides 36 provided for this purpose on the base 25 of the carriage 18, and, more precisely, on the plate 29 that this base 25 comprises.
- each slide 35 there is provided, for each slide 35, two cylinders 38, which, respectively, are arranged on each side and on the other side of such a slide 35.
- the body 39 of these jacks 38 is integral of the plate 29 of the base 25 while their piston rod 40 is integral with the corresponding slide 35.
- the means of angulation of the head of havage 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 with the upstream side and downstream side of the fixed guide 17, and by which it is articulated with slides 35, under the control of minus one cylinder 42.
- a single cylinder 42 is provided, and it extends obliquely from one of the slides 35 to superstructure 26, for example by being articulated by its body 43 to this slide 35 and by its piston rod 44 to this superstructure 26.
- the head of havage 20, and, more precisely, the cutting blade 34 thereof can advantageously follow any profile, and, by example, one or the other of the two profiles 12I, 12II shown diagrammatically in broken lines in Figure 1, while remaining tangent to such a profile.
- profile 12I is, in FIG. 1, a circular profile concentric with that of the fixed guide 17, while profile 12II is a profile which, also concentric with that of the fixed guide 17 in its central part, deviates laterally from the latter along two straight lines.
- the extension means to which the cutting head 20 comprise parallel to each other, at minus two cylinders 38 ', which, staggered longitudinally along the axis A1 of the fixed guide 17, in the manner of slides 35 previous, 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 cylinders 38 ' is integral with the plate 29, while their rod piston 40 'is integral with the superstructure 26, while being articulated to it.
- each of these jacks 38 ' is paired with another jack 38 ", which, moved away from it along the fixed guide 17, is can be ordered independently.
- Figure 3 it is a cylinder 50 additional to the piston rod 51 from which the piston rod 40 ', 40 "from one of the cylinders 38', 38".
- FIG. 5 it is a link 52, which, at one of its ends, is articulated to the superstructure 26, and which, at the other end, articulated to the piston rod 40 ', 40 "of one of the cylinders 38', 38 ".
- the fixed guide used could for example be generally frustoconical.
- extension means and / or angulation could include jacks.
