Definitions

  • the present invention relates to a motorized machine for digging trenches in the ground and laying elongated objects in the trench thus produced.
  • extended objects refers in particular to the cables of the electrical networks, for example medium and low voltages, telephone and optical systems intended to be buried, at variable depths, in trenches, but it could also relate to flexible pipes or conduits for specific fluidic networks.
  • the height of the latter is necessarily important (for example, nearly four meters for a trencher wheel diameter of 2.5 meters), which implies in addition to a substantial weight but in addition a high center of gravity.
  • This height must also take into account the distance between the base of the stem on the chassis of the ground and the rise of the motorized machine on the inclined ramps of the platform of a carrier vehicle to prevent the wheel slicer ( located at the rear of the machine) does not touch the ground when the machine tilts backwards when climbing the ramps.
  • the drum of the support device, on which the cable is wound is placed at the front of the chassis (as opposed to the digging device situated at the rear), the cable travels over the machine and the digging device passing on appropriate guide supports which are at a consistent height greater than that of the gallows (the highest point of the machine).
  • the present invention aims to overcome these disadvantages.
  • the height of the bracket on the chassis when it occupies the low position (retracted), is greatly reduced while giving an identical or even greater displacement travel between its two extreme low positions (return) and high (output), to the previous design.
  • the height of the telescopic stem in the lower position is lower, the top of the stem being at a level substantially identical to or less than the roof of the cab and / or the cowling of the engine unit of the machine, which now allows this one, with a smaller height, to circulate without obstacle along the roads.
  • the center of gravity of the telescopic stem is thus lowered ensuring a better overall stability, and the elongated objects are set up much more easily than previously on the top of the bracket, for their passage over the digging device, decreasing the risk of accidents for the operators responsible for passing the cables over the machine.
  • said frame comprises a transverse slide on which is slidably mounted said telescopic stem under the action of said corresponding control member, and said first and second members of said stem comprise vertical rails between which are respectively mounted sliding said second and third elements of said bracket, under the action of said corresponding control members.
  • said transverse displacement control member on said bracket and on said frame is mounted on reversible intermediate fasteners.
  • said body of control (cylinder) can ensure the translation to the left or right of the bracket by reversing the fasteners of said body of control (cylinder) on the fasteners linked to the first element of the bracket and the slideway of the chassis without disassembling said control member.
  • said device for supporting said elongated object is placed in front of said frame with respect to its direction of advance during the production of said trench, and said digging device is placed at the rear of said frame, guiding said elongate object being arranged on said frame and said digging device to bring said elongated object into said trench.
  • said digging device further comprises a controllable offset equipment of said trencher wheel, provided between the latter and said telescopic bracket and ensuring the transverse displacement of said wheel to lateral positions beyond the width of said wheel. chassis and its approximation or removal of said chassis.
  • This equipment facilitates the driving of the slicing wheel in work during the advance of the machine being able to place it precisely at the desired location by the operator, allows to perform a trench out of the template (in width) of the machine near an embankment or other, for example, adjusts the distance separating the slicing wheel from the frame according to the quantity of cuttings leaving the excavation carried out by the trencher wheel and depending on the depth of the trench made to avoid the clogging of the tracks and the chassis, and brings the wheel closer to the chassis when transporting the machine.
  • said digging device comprises a tilt correction equipment of said frame provided between said telescopic bracket and said trencher wheel, and to maintain it in a vertical work plane.
  • the trencher wheel is still in the vertical plane even if the ground, on which the machine is located, has a slope.
  • said equipment respectively offset and slope correction are related to each other, said correction equipment cant being associated with said telescopic stem and said offset equipment being associated with the frame of said slicing wheel.
  • said tilt correction equipment comprises a rotary ring about a horizontal axis, parallel to the plane of said frame, and composed of two relatively rotatable parts relative to each other about said axis, under the action of control members, and respectively associated with said carriage of the telescopic stem and said offset equipment.
  • said offset equipment may comprise, in a preferred embodiment, a box arm mounted at its ends about parallel vertical axes, one of which is connected to the second rotating portion of said ring and the other is connected to said trencher wheel, and control members respectively connecting said ring to said box arm and said box arm to said wheel frame for effecting said rotations about said vertical axes.

  • the stem 10 can slide on the slide 19 according to the stroke of the cylinder 21. Also, to ensure its movement to the opposite track or return to the initial position of Figures 5, 6 , it is simply necessary to reverse the assembly of fastening pins fasteners without touching the cylinder to advance transversely step by step (depending on the stroke of the cylinder).
