Definitions

  • the present invention relates to an apparatus for digging in the floor of deep trenches using milling drums mounted on a chassis.
  • Such an apparatus is already known in FR-A-2,578,876.
  • the length of cables separating the mast from the chassis is sufficient to allow the latter to be easily oriented in order to make it parallel to the trench that it is desired to make, even if the mast of the lifting machine is not not quite pointing in the right direction.
  • the length of cables separating the mast from the chassis makes it impossible to pivot the latter around its vertical axis. . It is then necessary to move the lifting machine to position its mast precisely with respect to the trench to be made.
  • the present invention aims to provide a simple and economical for the realization of trenches in the ground whose chassis is able to orient itself easily in the direction corresponding to that of the trench that we want to make.
  • the apparatus according to the invention also has the great advantage power, without appreciably modifying the position of the lifting machine, make trenches according to angular paths, for example to make walls around the perimeter of the interior courtyard of a building.
  • the subject of the present invention is an apparatus for carrying out of trenches in the ground of the type comprising a frame provided with drums milling at its lower part, characterized in that the chassis is supported at its upper part so that it can pivot around its vertical axis and in that it further comprises a flexible pipe by which the cuttings are raised to the surface, the end of said flexible pipe being arranged along said vertical axis of pivoting of the chassis and being able to pivot relative to said chassis.
  • each of these flexible pipes connects to the non-pivoting upper part of the chassis by an elbow, the upper branch of which is directed upwards, and which pivots relative to the vertical axis of the latter, and whose lower branch, which is substantially horizontal, is connected to the end of a flexible pipe section the other end of which is preferably connected vertically to the pivoting part of the chassis, said section being able to pivot about its axis at at least one point of its length, the lower end of the flexible pipe section being horizontally offset from the vertical branch of the elbow.
  • the horizontal parts of the elbows to which the flexible pipe sections are connected remain oriented substantially in the same direction, allowing the hoses to remain substantially parallel to each other.
  • the apparatus of FIG. 1 comprises, in the known manner, a chassis 1 which supports two milling drums 2 at its lower part rotatable.
  • the chassis 1 is suspended from the mast of a lifting device not represented by a muffle consisting of a multi-strand cable 3 and pulleys 4.
  • the chassis 1 is capable of pivoting around its vertical axis 5 thanks to a ball bearing 6 housed between the part upper 7 of the chassis and the base 8 of the muffle, as can be seen in section cut away in Figure 1.
  • a flexible pipe 9 for the removal of the cuttings ends at the chassis 1 along the vertical axis 5 of the latter, between the two pulleys 4 of the block.
  • This pipe 9 is connected to the chassis via a not shown rotating joint which allows it not to undergo torsion during pivoting of the chassis.
  • a plurality of flexible pipes 10 used to supply the device with energy hydraulic go down between the two pulleys 4 of the block to connect to the non-pivoting part of the chassis.
  • Each of these pipes leads to the upper branch of a elbow fitting 11 which is mounted on the non-pivoting part of the chassis, so that it can pivot around the axis of its branch which is arranged vertically.
  • the other branch of the elbow 11, which is horizontal, is connected to the upper end of a flexible pipe section 12 of which the lower end is vertically connected to the pivoting part of the frame.
  • Each section 12 enters at 13 into the pivoting part of the frame.
  • each section of flexible pipe 12 is connected to the horizontal branch of the elbow 11 so that it can pivot around its longitudinal axis, so that it does not undergo any twist when pivoting the chassis.
  • each of the two elbows 11 to which the upper ends of the sections 12 is represented by a circle in FIG. 2.
  • each elbow 11 pivots about the axis vertical of its upper branch.
  • each section of pipe 12 ends vertically at 14 on the pivoting part of the chassis, forming a arc, as can be seen in Figure 3, where we have schematically shown in solid line 12 a section of pipe in the position of chassis which is shown in solid lines in FIG. 2, and in lines interrupted 12 'that same stretch in the chassis position which is shown in broken lines in Figure 2.
