Definitions

  • This invention relates to a device for cutting through pavement courses with a rotary disk tool.
  • a device for cutting through pavement courses with rotary disk tools comprises a pneumatic or hydraulic hammer having a shank whereto a bracket is secured which carries a rotary disk tool bit set for rotation in a plane transverse to the road course, said bracket having a ground-contacting shoe articulated laterally thereto.
  • the device for cutting through road courses which comprises a pneumatic of hydraulic hammer 2 of a conventional type.
  • the device 1 is provided with a cutter bit including a rotatable disk 3 mounted for free rotary movement on an axial pin 4 which is carried at the ends of a bracket 5.
  • the bracket 5 defines at the top an attachment seat 6 for a conical coupling 7 formed by the enlarged tip of the shank 8 of the hammer 2.
  • the centre of the rotatable disk 3 is laid on the plane containing the axis of the hammer 2.
  • the rotatable disk 3 has two faces converging toward its edge as shown in Figure 2.
  • a ground-engaging shoe 9 is articulated to the pin 4 externally to the bracket 5 and raised at the leading end in the forward direction of the device and enclosing the disk 3.
  • the hammer 2 is carried on a slide 10 equipped with suitable forward movement means and communicates through a pipe 2a with a source of pressurized fluid, for example a compressor, in a manner known per se, and no further described or illustrated herein.
  • the slide 10 has, articulated frontally thereto on a cross- pin 11, a guide cylinder 12 having a square inside cross-section, wherein a complementary cross-section rod 13 is slidable which extends out of the cylinder.
  • the rod 13 carries at its free end a bracket 14 whereto there is fastened, as by screw means 15 and with the interposition of a set of adjustment spacers 16, a plate 17 which bears onto a pair of external protuberances 18 on the cylinder 12.
  • the plate 17 is formed with a pair of supports 19 in the proximity of the area of attachment of the rod 13 to the bracket 14, said supports 19 being adapted for cooperation with respective brackets 20 in clamping the transverse handles 21 of the hammer 2 to the plate 17.
  • the hammer 2 itself also bears onto the plate 17, through an elastic packing 22 and,accordingly, lies parallel to the guide cylinder 12.
  • the inclination of the guide cylinder 12 is adjustable in the vertical plane through inclination control means which, in the illustrated embodiment comprises a pneumatic cylinder 23 communicating with a source of pressurized fluid in a known manner (not illustrated) which is articulated at its ends, 24 and 25 respectively, to the slide 10 and a flange 26 rigid with the guide cylinder 12.
  • inclination control means which, in the illustrated embodiment comprises a pneumatic cylinder 23 communicating with a source of pressurized fluid in a known manner (not illustrated) which is articulated at its ends, 24 and 25 respectively, to the slide 10 and a flange 26 rigid with the guide cylinder 12.
  • the pneumatic cylinder 23, may be replaced by any suitable means for controlling the inclination of the guide cylinder 12, such as power assisted means or even a mechanical jack arrangement.
  • the flange 26 is provided with a pair of holes 27 whose centres are arranged to lie on an arc radius of the cross pin 11 corresponding with the centres of a plurality of holes 28 formed in a further flange 29 which projects from the slide 10. Said pair of holes 27 being axially alignable with any equally spaced pair of said plurality of holes 28, thereafter locking means such as screw means can be inserted through the axially aligned holes 27, 28 to "lock" the guide cylinder 12 at a desired inclination.
  • the flanges 26 and 29 are arranged to face each other and the articulation pin 11 is passed therethrough. Also adjustable is the position of the rod 13 along the guide cylinder 12, which may also be locked through the insertion of screw means engaging respective holes 30.
  • a vibrating plate indicated generally at 31 in the drawing and not described in detail because known per se is preferably mounted on the slide 10.
  • Appropriate holes 32 are provided in the slide 10 for mounting the vibrating plate 31.
  • the cylinder 12 may be mounted on a carriage which is moved forward by a pneumatic drive.
  • the hammer 2 In the working position, the hammer 2 has an axis which leans backwards with respect to the direction of forward movement A of the device 1, this inclination being determined by the position of the guide cylinder 12 whereto said hammer is parallely secured.
  • the inclination is adjustable, through the pneumatic cylinder 23, according to the characteristics of the pavement course to be cut.
