Definitions

  • Appl. NO.Z 470,560 57 ABSTRACT A public works machine comprises a frame on which Foreign pp c Dam a telescopic jib is pivotally mounted, means for con- May 21,1973 France 73.18363 trolling pivotal movement of the jib connected be tween the frame and a first section of the jib which is [52] US. Cl. 173/38; 173/43 pivotally mounted on the frame, means for controlling [51] Int. Cl.
  • the present invention relates to improvements in public works apparatus.
  • the tool is suspended from the end of that section of the telescopic jib which is pivoted on the frame of the apparatus.
  • the need to supply the fluid motor for operating the tool the ram of a grab or rotary motor of the auger by means of a flexible fluid conduit winder is avoided, this being necessary when the tool is suspended from a section of the jib which slides relative to that section which is pivoted on the frame.
  • the point of suspension of the tool describes an arc of circle, so that the tool is not maintained vertical and therefore cannot bore a vertical hole.
  • public works apparatus comprising:
  • a jib mounted on the frame comprising at least two telescopic sections, of which a first section is mounted on said frame for pivotal movement about a first axis and a second section is slidable relative to said first section;
  • a member mounted on said first section of said jib for pivotal movement about a second axis parallel to said first axis;
  • pivotal movement of said member is controlled by said sliding control means and said arm.
  • the working tool is driven by pressurized fluid, the fluid source being arranged on the frame.
  • FIG. 1 is an elevation of an embodiment of an apparatus in accordance with the invention, in the configuration presented prior to boring a hole;
  • FIG. 2 is an elevation of the apparatus of FIG. 1, but in the configuration presented after boring the hole.
  • the apparatus shown in FIG. 1 comprises a chassis l, which is as shown provided with wheels 2, and a turret 3, which is pivotably mounted on the chassis l for movement about an axis 4.
  • Stabilizer means 5, e.g. jacks, are attached to the chassis 1 and, in use, contact the ground 6.
  • a telescopic jib 7a is mounted on the turret 3 for pivotal movement about an axis 8, a ram 9a being connected between the jib and the turret.
  • the jib 7a comprises two sections 10a and 11a, section 10a being pivoted on the turret for movement about the axis 8 and section being slidably mounted within the section 10a.
  • a ram 12a is connected between the sections 10a and lla to control their relative positions.
  • the end of the section 10a remote from the axis 8 is provided with flanges 13a on which a lever or dipper-stick 15a is pivoted for movement about an axis 14a.
  • a rod 19a is pivoted for movement about axis of an idler pulley 18a.
  • the pulley 18a is mentioned because it is provided on the telescopic jib but it has no particular function as far as the present invention is concerned.
  • the rod is pivoted on the dipperstick 15a for movement about an intermediate axis 20a, and a support 22a of an auger 23a is suspended from the said dipper-stick 15a for movement about an end axis 21a.
  • the auger is provided with an hydraulic rotary drive motor 240, which is itself suspended from the support 22a for movement about an axis 25a perpendicular to the axis 21a.
  • This motor 240 is connected by two short, flexible conduits 26a to unions 27a arranged on the section 10a adjacent the flanges 13a.
  • the section 1111 is only partially contained in the section 10a, so that the dipper-stick 15a forms an obtuse angle with the section 1011.
  • the auger 23a is bearing on the ground 6 by its free end, but has not yet started to bore. It is arranged facing the position of the hole 28 which is to be bored, which hole has a vertical axis 29.
  • the retraction of the section 1117 into the section 10b has caused the rod 19a to come to 191) and the dipperstick to 1512, the various axes coming to 17b, 14b, 20b and 21b.
  • the flexible conduits have come to 261) and connect the unions 27b to the motor 24b of the auger 23b. It will be noted that the latter has bored the hole 28 with an effectively vertical axis 29.
  • the waste mate rial is arranged in a heap 31 around the opening of the hole 28.
  • Adoption of the auxiliary dipper-stick 15a and of the rod 190 has therefore, without any other modification of the apparatus, very simply enabled the suspension axis 210 of the auger to be kept on the vertical passing through the axis 29 of the hole 28.
  • the horizontal displacement of the axis 140 is compensated for by an equal and opposite horizontal displacement of the axis 21a, caused by the retraction of the section lla into the section 10a and the pivoting which results from this of the dipperstick from 15a to 15b.
  • the axis 21a thus remains permanently on the vertical passing through the axis 29 until it reaches 21b.
  • the auger could be replaced by any other suspended tool, for example a grab.
  • the jib could have more than two telescopic sections. It would then be sufficient to pivot the dipper-stick 15a on the section pivoted on the turret and the rod 19a on any other section to obtain the operation described above.
  • Public works apparatus comprising:
  • a jib mounted on the frame comprising at least two telescopic sections, of which a first section is mounted on said frame for pivotal movement about a first axis and a second section is slidable relative to said first section;
  • a member mounted on said first section of said jib for pivotal movement about a second axis parallel to said first axis;
  • pivotal movement of said member is controlled by said sliding control means and said arm.
