Definitions

  • the present invention relates to an apparatus for digging deep trenches in the ground using milling drums.
  • Devices of this type can dig trenches, the depth of which is generally of the order of a few tens of meters, but which can reach up to about 150 meters.
  • the inclination of the chassis is controlled using devices such as lateral pushers which are not entirely satisfactory, in particular because of their low positioning accuracy.
  • the present invention aims to provide a simple and economical device which can be guided reliably and precisely in a trench in progress.
  • the subject of the present invention is an apparatus for digging deep trenches in the ground comprising a chassis provided with milling drums at its lower part, characterized in that the upper part of the chassis is provided with at least one guide which comprises, in the direction parallel to the axes of the milling drums, two ends spaced apart by a constant distance substantially equal to the thickness of the trench, and which can take, during the operation of the apparatus, a position centered in which the upper part of the chassis is located approximately equidistant from the two ends of the guide member, a position offset from one side of the chassis in which the upper part of the chassis is brought closer to one of the ends of the guiding by a predetermined distance, and a position offset from the other side of the chassis in which the upper part of the chassis is brought closer to a predetermined distance from the other end of the guide member.
  • the apparatus according to the invention has the advantage that its chassis is permanently guided in the trench, whatever the position of the guide member relative to the chassis.
  • the width of the guide member being substantially equal to the thickness of the trench, it is avoided that too much lateral play appears and lead to improper positioning of the chassis.
  • the guide member consists of a three-position hydraulic cylinder mounted on the chassis and the piston rod of which extends over the entire thickness of the chassis.
  • the piston rod comprises an annular flange which seals between two annular chambers located on either side of the actuator into which a pressurized fluid is introduced to maneuver the actuator.
  • the movable stop is in the form of a cylinder section which is housed around the piston rod, on one side of the flange of the latter.
  • the movable stop which thus undergoes the thrust of the pressurized fluid used to control the jack, delimits a sealed annular chamber between itself and said flange.
  • the cylinder body has an additional fluid intake orifice which opens into the annular volume between the movable stop and the flange of the piston rod.
  • the movable stopper is preferably positioned substantially in the central part of the cylinder body, which for this purpose comprises a bearing on which a projecting part of the movable stopper rests when the latter is subject to fluid thrust.
  • the movable stop has a fluid cross section greater than that of the annular flange of the piston rod so that, when the rod is held in the intermediate position against the movable stop, the thrust of the fluid on the rod remains less than the antagonistic thrust of the fluid on the movable stop.
  • the jack can take three stable positions by being controlled by a single pressurized fluid.
  • a jack according to the invention it is possible to control a jack according to the invention to make it hang, as desired, one of its three stable positions by injecting a fluid at appropriate points on the jack without modifying the pressure to which this fluid is subjected.
  • the fixed stops there are on the outer wall of the chassis, at the height of the sliding pads, fixed stops against which the end pads of the stop member bear, the fixed stops being preferably adjustable in thickness.
  • the stroke of the guide member is limited on one side or the other of the chassis.
  • the sliding pads are articulated around horizontal axes at the end of the guide member which supports them.
  • two hydraulic cylinders are arranged in parallel one above the other to support the same pair of sliding pads.
  • FIGS. 1 and 2 represent, seen from the side, an apparatus according to the invention which makes a trench 1 in a terrain 2.
  • the apparatus comprises a chassis 3, provided at its lower part with a pair of milling drums 4 (only one of which is visible in side view) which are rotated around axes 5 in opposite directions.
  • the upper part of the chassis 3 a is provided with a guide member 6.
  • two pads 7 and 8 are each secured to one end of the guide member 6, so as to facilitate movement down or up of the chassis 3.
  • the spacing between the two pads 7 and 8 is kept constant and substantially equal to the thickness of the trench 1 dug by the milling drums.
  • the trench 1 has good verticality.
  • the guide member 6 is placed centrally, the upper portion 3a of the frame being thus equidistant from the two walls of the trench 1.
  • the device can continue its downward progression in the vertical direction.
  • FIG. 2 it can be seen that the trench 1 is slightly moved away from the initially planned tracing which is shown in broken lines 9.
  • the guide member 6 has been placed in a position offset to the right with respect to the chassis, which causes the chassis 3 to tilt slightly relative to the trench and a positioning of the milling drums. 4 suitable for bringing the appliance back to the vicinity of route 9.
  • hinge pins 10 connect the pads 7 and 8 to the central part of the guide member 6.
  • FIG. 3 Shown in Figure 3 is a closer view in section of the upper part 3a of the chassis in which it is seen that the central portion of the guide member 6 is constituted by two identical cylinders arranged parallel one above the other.
  • each jack comprises a hollow cylindrical body 11 inside which slides a piston rod 12, each end of which is connected at 10 to a shoe 7, 8.
  • the articulation 10 of the lower jack is also vertically sliding, which makes it possible to tilt the pads 7 and 8 as in the case of FIG. 2.
  • the flange 14 has a seal 17 and each of the bearings 13 also has a seal 18.
  • the movable stop 19 is free to slide axially around the piston rod 12.
  • the fluid is supplied to the actuator through three orifices 22, 23 and 24 opening respectively into the annular chambers 15, 21 and 16.
  • Conduits 25, 26, 27 are provided in the upper part 3 a of the chassis for conveying the fluid supplied by pipes not shown which descend from the surface of the ground and are connected to the upper part 3 a of the chassis.
  • Lines 25, 26 and 27 have extensions 28, 29 and 30 which interconnect the chambers corresponding 15, 21 and 16 of the two hydraulic cylinders to ensure simultaneous operation of the latter.
  • the thrust 32 is slightly greater than the thrust 31.
  • FIG. 3 there is also shown in broken lines the location of fixed external stops 33 secured to the external wall of the upper part 3 a of the chassis, at the height of the sliding pads 7 and 8.
