Definitions

  • the invention relates to an improved machine for producing underground galleries; it aims at a machine making it possible to dig an underground hose and to progressively equip it, as the machine advances, with covering elements supporting the earth such as pipes or segments.
  • Such machines are already known which are essentially composed of a hydraulic shield and a slaughter device housed inside the shield.
  • the slaughtering device generally constituted by a cutter carried by an arm suspended in the upper part of the shield, makes it possible to dig and split the earth at the front of the shield, this earth being eliminated towards the rear by a conveyor; the hydraulic shield which includes a thrust ring on which a hydraulic thrust system is coupled, allows the shield to advance after completion of the appropriate front earthwork; to generate this progression, the thrust ring is supported on the pipes or segments already installed at the rear of the machine and the hydraulic thrust system hitched at its other end to the shield exerts an effort on the latter advancement (US-A-4,190,294, US-A-4,203,626).
  • the curves are very difficult to achieve with this type of machine and require earthworks outside the profile of large sections and therefore a relatively large staff; moreover, the curves produced are with very large radii (the radii of curvature reached being generally greater than approximately 100 times the diameter of the gallery).
  • the curves produced are with very large radii (the radii of curvature reached being generally greater than approximately 100 times the diameter of the gallery).
  • it sometimes turns out to be impossible to make curves with known machines and professionals are forced to resort to entirely manual earthworks.
  • these machines are ill-suited to digging loose ground which tends to "stuff" the cutter with strawberries and absorb very large powers.
  • patent EP-A-0 024 445 describes a slaughter device composed of an arm with cascading articulations (of the hydraulic shovel type with horizontal axis); this arm is mounted in a movable frame in translation by means of a rail / gutter system which carries the entire slaughter device in order to allow complete sweeping of the slaughter section.
  • a slaughter device is incompatible with the digging of pronounced curves. Indeed, in the pronounced curves, the front case subjected to considerable asymmetric stresses necessarily undergoes an ovalization which results either in jamming effects either by excessive play in the raii / gutter system, which disrupts the operation of the machine.
  • the forces that apply to the bucket are reflected by enormous omni-directional stresses on the rail / gutter system given the length of the lever arm of these forces.
  • the present invention proposes to remedy the faults of the known machines mentioned above, by providing an improved machine, designed to operate according to the same general principle as the known machines.
  • An essential objective of the invention is in particular to authorize the production of much more pronounced curves, without having to perform earthworks outside of the profiles; the invention aims in particular to allow curves to be produced, the radii of which can be easily adjusted to a minimum value of the order of 15 times the diameter of the structure.
  • Another objective is to provide a machine adapted to work in any terrain and in particular in soft ground as well in straight lines as in curved lines.
  • An objective of the invention is thus to provide a universal machine which can, without difficulty, dig galleries in soils with layers of different natures.
  • the floating attachment between the cutting kit and the assembly skirt is adapted so as to allow said kit and said skirt an adjustable relative pivoting up to a value of approximately 4 °.
  • the cutting kit comprises, secured to its rear part, an external centering ring in which is fitted an internal centering ring secured to the front of the assembly skirt, said rings being dimensioned so as to be spaced from a functional clearance adapted to allow the aforementioned relative pivoting between the cutting bag and the assembly skirt.
  • the front part of the shield (cutting bag) which supports the slaughter device can be oriented in a chosen direction so as to form an adjustable angle relative to the rear part (skirt d 'assembly), which allows the placement of the covering elements.
  • the deflection of the cutting kit is obtained by independently controlling the thrust cylinders during shield progression operations: the cylinders located on the outside of the curve to be produced are made to undergo a greater elongation than those located on the inside, the elongation ratios defining the steering angle a.
  • the slaughtering device can thus work in an angular direction offset from the previous direction, while allowing, on the one hand, a traditional type of work in line with the profile of the cutting kit, on the other hand , a conventional positioning of the covering elements in the assembly skirt.
  • the structure of the felling device allows the arm to easily sweep the entire section of the cutting face (in front of the cutting bag) by the combined play of the 360 ° rotation of the rotating frame and the maneuvers of the arm relative to said rotating frame.
  • the tool can be brought to work in all positions; under these conditions, the arm is advantageously equipped with a bucket capable of working in mound or retro, which allows digging without difficulty as well as soft ground than hard ground.
  • the improved machine shown by way of example in FIGS. 1, 2, 3, 4 and 5 is intended for the production of underground galleries, of diameter which can vary between 1.80 and 6 meters.
  • This machine essentially comprises, on the one hand, a shield made up of two parts, a front cutting kit 1 and a rear assembly skirt 2, on the other hand, a slaughtering device 3 carried by the cutting kit 1.
  • the cutting kit 1 is in the form of a cylindrical steel tube provided with a cap 1a at its front part; at its rear part, it is provided with an outer centering ring 4 which is welded to said kit so that its thickness protrudes outside the kit 1, as shown in FIG. 5.
  • traction pads such as 5, for example six in number, are welded internally to the rear of the cutting kit 1 and distributed around the periphery thereof, in the vicinity of its junction with the ring 4.
  • annular support 6 on which are articulated several hydraulic cylinders such as 7 (for example six in number), distributed over the shielded perimeter .
  • the body of each of these jacks is articulated on the support 6 by a conventional yoke.
  • assembly skirt 2 is in the form of a cylindrical steel tube, the diameter of which is slightly larger than that of the kit 1 is of the order of that of the outer ring 4 welded to the back of said kit.
  • an internal centering ring 3 is welded, the thickness of which protrudes inside said skirt as shown in FIG. 5.
  • the ring 8 is fitted into the ring 4, with a functional play between them, adapted to allow a relative pivoting of the cutting kit with respect to the assembly skirt around any axis orthogonal to the axis of these elements.
  • the rings 4 and 8 which overlap over a variable longitudinal distance as a function of the relative position of the skirt and the case, provide guiding and relative centering of these elements, avoiding any risk of transverse shift.
  • each coupling lug 9 is provided with 'a light 9a, of longitudinal dimension much greater than that of a traction pad 5 and of transverse dimension slightly greater than that of the latter.
  • Each of the studs 5 penetrates into a lumen 9a of a tab, so that all of these members constitute a floating attachment subjecting the skirt 2 and the kit 1, d to each other with a determined clearance.
  • the skirt 2 guides a thrust ring 10 which is slidably mounted therein.
  • a thrust ring 10 which is slidably mounted therein.
  • On this ring are coupled, in a conventional manner in themselves, the movable rods of the hydraulic cylinders 7.
  • These cylinders are equipped with a hydraulic distribution system allowing them to be supplied and to be controlled independently so as to be able to individually adjust their elongation and adjust thus the relative angular position of the kit 1 relative to the skirt 2.
  • the slaughtering device 3 carried by the sharp kit 1 comprises a frame 11 having three tripod-shaped extensions, by which it is fixed inside the cutting kit 1, towards the rear portion thereof.
  • This frame forms around the axis of the kit a substantially vertical platform 11a, said frame and its platform being hollowed out in the central region of your kit in order to delimit a hollow central volume.
  • a rotating frame 12 is mounted at the front of the frame 11 on the vertical platform 11a by means of a crown of bearings of known type, (symbolized at 13 in Figures 1 and 2); this crown of horizontal axis coinciding with the axis of the kit can be of the crossed roller type, its external cage being secured to the platform 11a and its internal cage to the chassis 12.
  • the latter has teeth 14 engaged with a pinion 15 which is articulated on the platform 11a and driven in rotation by a hydraulic motor 16 carried at the rear by said platform 11a.
  • the rotating frame 12 can thus be rotated 360 ° about a horizontal axis substantially coinciding with the axis of the sharp case.
  • a felling arm 18 On this rotating chassis is articulated a felling arm 18, by an axis 17 parallel to the plane of the platform 11 a and located in the vicinity thereof, this articulation axis being eccentric relative to the fictitious center of the platform.
  • the felling arm 18 has a rear extension 18a which is housed in the hollow part of the frame 11.
  • the movable rod of an actuating cylinder 20 is coupled by an axis 19.
  • This cylinder is tilted back as shown in Figure 1 and its body is coupled to a front extension 12a of the rotating frame, at a coupling point 21 located opposite the articulation point 17 of the arm, relative to the axis of the sharp case.
  • the articulation point 17 of the arm and the coupling points 19 and 21 of the maneuvering cylinder are thus arranged in a triangle and the arrangement described above of these elements makes it possible both to guarantee good efficiency of the maneuvering cylinder which that is the position of the arm 18 and considerably reduce the space requirement at the front of the platform so as to clear the work area and allow the entire surface of this area to be swept by the arm (despite the division of the shield into two parts, which conditions a significant reduction in the longitudinal dimension of the cutting bag in which the slaughter device is housed).
  • the felling arm 18 is advantageously telescopic and comprises two members 18b, 18c mounted to slide relative to one another and a hydraulic cylinder 22 located inside the latter and coupled to them in order to move the member 18b relative to the member 18c in the direction of a retraction or a longitudinal extension.
  • the member 18b is equipped at its end with a bucket 23 which is associated with conventional hydraulic maneuvering means, comprising a hydraulic cylinder 24 and transmission rods 25, in order to allow the bucket to be disposed both in position butte only in retro position.
  • conventional hydraulic maneuvering means comprising a hydraulic cylinder 24 and transmission rods 25, in order to allow the bucket to be disposed both in position butte only in retro position.
  • the various cylinders integral with the rotary chassis 12 (cylinders 20, 22 and 24) are supplied with pressurized oil by a hydraulic rotary joint of the conventional type 26.
  • the above-described felling device is capable of effectively digging both loose and harder soils; by the play of the sweeping of the arm and the 360 ° rotation, the bucket can be brought to work indifferently in hillock or in retro, the telescopic nature of the arm allowing a good penetration of the bucket forward.
  • Such a slaughter device is adapted to the structure in two distinct parts of the shield and is free from the defects of conventional strawberry devices.
  • Figures 6 to 10 illustrate the operation of the machine to produce a curved gallery.
  • the machine is assumed in the configuration of FIG. 6.
  • the axis X of the cutting kit 1 forms an angle a with the axis Y of the assembly skirt 2, this angle being a function of the curvature of the gallery to achieve.
  • the jacks 7 are in the retracted state, those situated outside the curve having greater elongations adapted to the variable distances which separate the coupling points of the various jacks on the front support 6 and on the sliding ring 10 The latter is in its most forward position, pressing against the last coverings which have been put in place in the skirt (segments V).
  • kit 1 and skirt 2 are in the position shown diagrammatically in FIG. 7. Shims of different lengths, as shown diagrammatically in broken lines at 27, can be put in place to block the skirt and the sharp kit in the appropriate angular configuration, defined by the differential elongation of the cylinders 7.
  • These removable wedges can in particular be manually placed against the traction studs 5 in the slots of the coupling lugs 9. The set of wedges thus put in place allows, during the shield's progression movements, to keep precisely the value of the angle a between the X and Y axes of the case and the skirt.
  • the jacks 7 are operated independently in the direction of extension to move the shield forward. (figure 8). This movement is obtained by pressing the pushing ring 10 on the segments V which keep this ring stationary: under the push of the jacks 7, the cutting bag 1 is therefore caused to slide forward in the new length hollowed out and the assembly skirt 2 follows, the progression movement being transmitted to it by the traction pads 5 engaged with the lugs 9 as well as by the jacks 7 which link the cutting kit and the assembly skirt.
  • the jacks 7 are retracted by maneuvering them independently so as to preserve their differential elongation (FIG. 9): the sliding ring is then brought back towards the front of the assembly skirt 2.
  • Such a machine in which the cutting kit 1 and the assembly skirt 2 are capable of forming an angle reaching up to 4 ° makes it possible without difficulty to produce treats having curvatures reaching up to 15 times their diameter: three people are enough to serve it and the average progress can be around 5 meters per 8 hour shift.
