Definitions

  • the subject of the present invention is a drilling machine of the type comprising a frame and at least one pair of rotary tools of drilling mounted on this chassis, these rotary drilling tools representing substantially the same axis of rotation.
  • FIG. 1 shows a drilling apparatus 10 constituted mainly by a platform 12 equipped with an arrow 14 to the upper end 14a of which is suspended a machine of drilling 16 via cables 18.
  • the drilling machine 16 has a frame 20 at the lower end of which are mounted two pairs of rotary drilling tools or cutters 22 and 24.
  • Each pair of tools 22 or 24 is constituted by two drilling tools for example 26 and 28 as best shown in FIG. 3, these drilling tools being rotatably mounted around axes that are most often confused, the axis
  • the two pairs of tools have parallel axes of rotation.
  • each pair of tools is rotatably mounted in a support plate 32 integral with the end lower 20a of the chassis of the drilling machine.
  • the drill rig also includes a flexible hose 34 associated with suction ports 36 and a suction pump 38 for cause the removal of cuttings resulting from the action of the tools of drilling.
  • the drilling machine also has feed hoses hydraulic motors driving pairs of rotary tools 22 and 24.
  • the presence of the support plate 32 between the drilling tools 26 and 28 of the same pair creates an interval e between the zones of action of the drilling tools on the face of size 40.
  • This gap 39 leaves in the cutting edge a redan 42.
  • the plate 32 has an edge 32a usually semicircular semi-oval or polygonal shape.
  • redan 42 opposes or opposes the progression of the tool of especially if the soil in which the drilling is done is relatively hard.
  • the redan 42 typically has a height of the order of 250 mm and a thickness of the order of 70 mm.
  • the lower edge 32a of the plate 32 which is a cylindrical surface portion in the broad sense of the term whose generatrices are parallel to the axis of rotation of the tools, exerts on the summit of the redan a compression effort. Because of jolts of the machine, lateral parasitic forces induce bending and shearing forces that promote the breaking of the redan.
  • An object of the present invention is to provide a machine for drilling of the type mentioned above which improves the progressive disintegration of the redan to improve the overall efficiency of the drilling machine especially in the case of drilling in hard terrain.
  • the drilling machine includes a chassis; at least one pair of rotary drilling tools having substantially the same axis of rotation; a support set secured to the frame for rotatably supporting said pair of tools, said support assembly presenting towards the front of the waist an edge extending between the tools of said pair of tools, said machine is characterized in that it further comprises means mounted on said support assembly to create at least one jet of liquid at very high pressure directed towards the face of size between the action areas of said pair of tools; whereby said jet of liquid at very high pressure disintegrates the redan that forms in the face between areas action of said pair of rotary tools.
  • the jet creation means comprise at least one less a nozzle fed with liquid under very high pressure opening in said edge of the support assembly.
  • the previously defined drilling machine is characterized in that less over part of its length, said edge has a non symmetrical with respect to said median plane, whereby said face dissymmetrical exerts a bending force on the redan formed between areas of action of said pair of tools, to cause disintegration said redan.
  • the edge of the support assembly has a non-symmetrical surface with respect to at the median plane of the support element, that is, in relation to the direction drilling against the redan that tends to form between the rotary tools of the same pair, a mechanical bending action is exerted on the redan by this face because of its orientation, which favors its disintegration with respect to a compression action since, as it has been indicated, the redan is more sensitive to a bending action than to a compression section.
  • FIG. 4 there is shown the plate 32 fixed at the end lower part of the frame 20a of the drilling machine and which serves for mounting and supporting the pair of tools 26, 28.
  • This plate comprises a central recess 50 for mounting motors and drums carrying the drilling elements.
  • This figure shows the pipes 52 supplying liquid under pressure of engines drive tools drilling.
  • FIG. 4 there is shown simplified way, nozzles such as 54 for creating jets of liquid to very high pressure which are formed in the edge 32a of the plate 32 turned towards the front of size 40 and more precisely towards redan 42. These nozzles thus produce jets of liquid under pressure 56 directed towards the redan over its entire width, that is to say in the perpendicular direction in the plane of Figure 3.
  • the nozzles 54 are preferably fed by pipes such as 57 drilled in the thickness of plate 32. These nozzle supply lines 57 are connected to hydraulic supply hoses 58 mounted in parallel with the main supply hoses for hydraulic motors.
  • the nozzles 54 are mounted inside the plate 32 so that their output 54a is in withdrawal relative to the lower edges 32a of the plate 32.
  • bores 58 are drilled in the edge of the plate 32 to allow the output of the high pressure jets delivered by the nozzles 54.
  • the pressure of the liquid used to create the jets is of the order of 100 to 200 MPa.
  • the lower edge 32a of the plate 32 no longer consists of a cylindrical surface whose generators are perpendicular to the direction of drilling but by a succession of alternating preference of unsymmetrical faces with respect to the median plane pp 'of the plate 32.
  • These faces may consist of flat surfaces or left surfaces.
  • it is fixed on the edge 32a of the plate 32, prism-shaped elements such as than 60 that have an active face 62 that does with the direction F of drilling an angle between 30 and 60 degrees and preferably equal to 45 degrees.
  • these prismatic elements 60 are alternated with respect to the median plane P, P 'of the plate 32 in such a manner that the active faces 62 are alternately on one side and the other of the median plane P, P '.
  • the nozzles 54 are then mounted in the prismatic parts 60 and the supply lines extend into these rooms.
  • FIGS. 6 and 6A a variant of FIG. realization of the parts to apply the bending force to redan 42.
  • the prismatic parts 70 fixed on the edge 32a of the plate 32 have in cross section the shape of a trapezium whose small active base 72 has a reduced dimension.
  • the longitudinal axes x, x 'of the pieces 70 make an angle b with the median plane P, P 'of the plate 32.
  • the angle b is, for example, of the order from 30 to 60 degrees.
