Definitions

  • the present invention relates to an apparatus for digging deep trenches in the ground using milling drums mounted on a chassis.
  • Such apparatus is already known in which milling drums driven in rotation in opposite directions are mounted on a chassis, itself suspended from the mast of a lifting machine by means of cables.
  • 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 device for making trenches in the ground, the chassis of which is able to orient itself easily in the direction corresponding to that of the trench which it is desired to make.
  • the apparatus according to the invention also has the great advantage of being able, without appreciably modifying the position of the lifting machine, to produce trenches according to angular traces, for example to produce walls around the periphery of the inner courtyard d 'a building.
  • the present invention relates to an apparatus for making trenches in the ground of the type comprising a chassis provided with milling drums at its lower part, characterized in that the chassis is supported at its upper part so as to be able to pivot around of its vertical axis.
  • the chassis can be pivoted about its vertical axis, without imposing a twist on the cables which support it, which allows it to be easily positioned in the direction of the trench that is desired. even when the layout of the trench has angular parts.
  • the flexible pipe by which the cuttings are brought to the surface is situated in the vertical axis of pivoting of the chassis, the end of said flexible pipe preferably being able to pivot relative to the chassis so as not to be subjected to a twist which could damage it.
  • each of these flexible pipes is connected to the upper non-pivoting part of the chassis by an elbow whose upper branch 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 around its axis at at least one point along its length, the lower end of the flexible pipe section being offset horizontally relative to 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, which allows the hoses to remain substantially parallel to each other.
  • the apparatus of Figure 1 comprises, in known manner, a frame 1 which supports at its lower part two milling drums 2 rotatable.
  • the chassis 1 is suspended from the mast of a lifting device, not shown, by means of a block formed by a multi-strand cable 3 and pulleys 4.
  • the chassis 1 is capable of pivoting about its vertical axis 5 thanks to a ball bearing 6 housed between the upper part 7 of the chassis and the base 8 of the muffle, as can be seen in cutaway torn off on figure 1.
  • a flexible pipe 9 for removing 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 by means of a not shown rotating joint which allows it not to undergo torsion during the pivoting of the chassis.
  • a plurality of flexible pipes 10 serving to supply the appliance with hydraulic energy descend between the two pulleys 4 of the block to connect to the non-pivoting part of the chassis.
  • Each of these pipes ends at the upper branch of an elbow-shaped connector 11 which is mounted on the non-pivoting part of the chassis, so as to be able to pivot around the axis of its upper 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 chassis.
  • Each section 12 enters at 13 into the pivoting part of the chassis.
  • each flexible pipe section 12 is connected to the horizontal branch of the elbow 11 so as to be able to pivot around its longitudinal axis, so that it does not undergo any torsion during the pivoting of the chassis.
  • FIGS. 2 and 3 show schematically the relative positions of two sections of flexible pipes 12, before and after rotation of approximately 45 ° from the lower part of the chassis 1.
  • each of the two elbows 11 to which the upper ends of the sections 12 are connected is represented by a circle in FIG. 2.
  • each elbow 11 pivots about the vertical axis of its upper branch.
  • each section of pipe 12 terminates vertically at 14 on the pivoting part of the chassis by forming an arc, as can be seen in FIG. 3, where a section of pipe is schematically shown in solid line 12 in the position of the chassis which is shown in solid lines in FIG. 2, and in broken lines 12 ′ this same section in the position of the chassis which is represented in broken lines in FIG. 2.
