Definitions

  • the frame also supports a bin containing the hot bitumen aggregate that, retrieved by a conveyor belt, is deposited on the surface being asphalted by the action of a pair of worm screws standing side by side, set crossways to the machine's direction of travel and made to rotate by a mechanical transmission unit.
  • bitumen aggregate While the bitumen aggregate is still hot, it is uniformly distributed over the road coarse and then compacted by means of a device, called “grader unit”, set behind the worm screws with respect to the machine's direction of travel.
  • the grader unit is connected to the end of a pair of heavy-duty arms set on the two sides of the machine pivoted to the machine's frame and with hydraulic jacks on the other end suited to raising and lowering the grader unit according to work needs.
  • the grader unit comprises compacting means and a plowshare component basically consisting of a heavy-duty plate bent to form an L-shape set crossways to the machine's direction of travel, with the longer wing basically perpendicular to the road coarse and the shorter wing parallel to the actual coarse.
  • the plowshare spreads the bitumen aggregate distributed by the worm screws preparing it for compacting performed by compacting means comprising a vertically oscillating beam set crossways to the machine's direction of travel, and made to vibrate by a device connected to it.
  • These second compacting means carry out the vibratory finishing of the shoulders of the road course, adjacent to the central section, and these shoulders may be varied in width depending on work needs.
  • the same second compacting means each have, along one side of the machine, a supporting meansing a flat element with an essentially longitudinal construction.
  • the flat element is vertically mobile with respect to its supporting means, so that it can be lowered until it scrapes along the road course during the machine's work cycle to perform its function of side stop to the bitumen aggregate inside the work area of the vibratory finisher.
  • the vibratory finishing machine On completion of work on the road course, the vibratory finishing machine is set-up in its compacted format in order to facilitate transfer to another location.
  • the aforesaid second lateral compacting means which may be extended according to the needs of the work performed, are made to retract against the central compacting means and, together with the latter, they are then lifted by operating the hydraulic jacks.
  • a first scope of the finding is to produce a self-driven vibratory finishing machine that allows to reduce the machine's overall width so that it is allowed to circulate freely and facilitate its transfer from one place to another.
  • Another scope of the finding is to obtain the reduction in overall width by making simple manoeuvres, reducing the operator's actions and efforts to a minimum.
  • a self-driven vibratory finishing machine for asphalting road surfaces that, in accordance with the main claim, comprises a frame housing means of traction and shaped to provide a driver's cab and supporting:
  • An advantage of the finding is that said joining means allow the supporting means to move vertically along their corresponding vertical rotation axis in order to take each supporting means from its work position to its uppermost position and subsequently to its compact set-up without interfering with other components on the machine.
  • said joining means comprise a kingpin connected to said second compacting means slidingly coupled with a cylindrical projection belonging to the same supporting means; a hole is made through said kingpin to receive a pin suited to holding each supporting means in its uppermost position.
  • the lifting means of each support comprise a flexible cable with one end connected to the actual support and the other end to the main frame of the machine.
  • the self-driven vibratory finishing machine for asphalting road surfaces under this finding is illustrated in fig. 1, where it is generally indicated by number 1 and comprises a frame 2 housing means of traction and shaped to provide a driver's cab 3.
  • the frame 2 also supports the storage means of the bitumen aggregate B to be deposited, consisting of a mobile walled bin 4.
  • the aggregate B by a suitable distribution means preferably consisting of a conveyor belt not illustrated, is deposited over the road surface 5 being asphalted.
  • bitumen aggregate B is then compacted by the action of a vibrating beam belonging to a grader unit, generally indicated by 6, basically comprising a plowshare, first central compacting means 100 shown in fig. 3, and a pair of second compacting means 7, all set crossways to the direction of travel A of the machine.
  • the second compacting means 7 are each located on one of the two sides of the machine 1, as can be seen in fig. 7, and are set to the side and basically parallel to the first central compacting means indicated by 100.
  • the machine 1 is designed so that the second compacting means 7 can each be independently extensible crossways to the direction of travel A of the machine, to allow a widening of the work area.
  • each of the second compacting means 7 has supporting means 8 with an essentially longitudinal construction for a flat element 9, also essentially longitudinal in construction, vertically mobile with respect to its supporting means 8 which it is connected to by a pair of chains 91. Its movement is guided by the slotted holes 81 made in the supporting means 8 working together, preferably but not necessarily, with dowels 95 connected* to the flat elements 9, to enable its adjustment in height from the ground 5.
  • the adjustment is obtained by operating the pair of handwheels 10 that, during the work cycle, enable the lowering of the flat element 9 until it comes into contact with the surface being asphalted 5, to side stop the layer of bitumen aggregate B and, while transferring the machine, to lift it from the ground.
  • the supporting means 8 are connected to their corresponding second compacting means 7 by joining means generally indicated by 11, set at one end of the supporting means 8.
  • joining means 11 produce a vertical rotation axis X for each supporting means 8 and comprise a C-shaped stirrup 111 belonging to the second compacting means 7, having a gudgeon 112 which slidingly couples the supporting means 8 by a cylindrical projection 81.
  • the kingpin 112 also allows the supporting means 8 to move vertically along the same rotation axis X enabling the flat element 9 to be taken to a higher level than the footboard 12;
  • the vertical movement of the flat element 9 and thereby the supporting means 8 is obtained by the lifting means comprising a flexible cable 14 with one end hooked extractably to a lug 141 belonging to the frame 2 of the machine and the other end to a second lug 142 belonging to the supporting means 8.
  • a hole is made through the kingpin 112 suited to receiving a pin 13 which, when the supporting means is set in its uppermost position, is inserted beneath the cylindrical projection 81, thereby allowing to bear the actual supporting means 8.
  • a hole 83 is also made through each of the supporting means 8, as illustrated in fig. 3, suited to receive a screw 15 that allows to connect the supporting means 8 to the second compacting means 7 when it is in its work position, as illustrated in figures 2 and 3, and to the first compacting means 100 when it is in its compact set-up, as illustrated in fig. 6.
  • the machine 1 set-up for work has the flat element 9 positioned as illustrated in fig. 2 by the solid line, with the supporting means 8 connected rigidly to the second compacting means 7 by screw 15.
  • the second compacting means 7, which may eventually be extended, are made to retract against of the first central compacting means, as illustrated in fig. 3.
  • the operator as can be seen in fig. 4, extend laterally each of the second compacting means 7 in direction of the arrow C, drawing each cable 14 under tension.
  • the supporting means 8 is forced to move vertically guided by the kingpin 112 and by the slotted hole 81 dowel 95 combination, until it reaches its uppermost position illustrated as a dotted line in fig. 2.
  • the bottom end 142 of the cable 14 is then unhooked from its lug to let the second compacting means 7 fully retract.
  • each supporting means 8 turns each supporting means 8 by approximately 270°, first taking it to an intermediary position by turning it approximately 180°, as illustrated in fig. 5 and then to its compact position illustrated in figures 6 and 7.
  • the supporting means 8 and the flat element 9, when in their final compact position are set crossways to the direction of travel A of the machine 1, and how the two kingpins 112, are each square with the machine's direction of travel, parallel and kept apart to prevent any interference between supporting means 8 and flat elements 9.
  • each supporting means 8 can lock to the central compacting means 100 of the machine 1, preferably but not necessarily using the same screw 15.
  • the self-driven vibratory finishing machine 1 can be moved without danger, and it is without protrusions and has an overall width of less than two and a half meters.
