Definitions

  • the subject of the invention is an earthmoving machine in soft or highly uneven terrain, in particular for the cleaning and dredging of ponds, marshes or canals.
  • Wheeled vehicles have very limited possibilities due to the risk of getting bogged down. Dredges can only operate on bodies of water with sufficient depth, which is not often the case in ponds, marshes or canals.
  • European patent 0 017 593 of the applicant describes an earth-moving machine in soft ground, in particular for the cleaning and dredging of ponds, marshes or canals of the type consisting of a carrying structure provided with support members such as wheels or skids and lateral stabilizers and equipped with at least one earthmoving member such as a shovel, this member being controlled from a cockpit on the carrying structure.
  • These known devices have the drawback of frequently requiring the presence of two operators.
  • movement can practically only be done in a straight line.
  • the subject of the invention is a machine of the indicated type which does not have the aforementioned drawbacks.
  • the device according to the invention is particularly remarkable in that the central stabilizer is integral with a control carriage moving between two side members of the carrying structure, at least two support members being liftable and mounted on telescopic arms ensuring the translation control of these organs.
  • the machine comprises four support members such as wheels, two of which are telescopic, these four members being provided with individual lifting controls.
  • the machine consists essentially of a support structure or chassis 1 comprising two U-shaped section beams 1 ′, 1 ".
  • floats 2 of reduced dimensions are fixed on the framework, for example by welding, to stiffen the structure and avoid its buckling
  • the floats 2 act simply as reinforcing elements and are not dimensioned to ensure the buoyancy of the craft.
  • One or more earthworks for example excavators, are mounted on the supporting structure.
  • Such a member is shown schematically in Figures 13 and 14. It can be of any suitable type.
  • the machine rests on the ground by four support members 3 ', 3 ", 8', 8" shown in the form of wheels, but which can also be constituted, for example, by support pads.
  • the wheel lifting control is provided by hydraulic cylinders 5, 6.
  • the wheels 6 ', 6" are driven and the wheels 3' , 3 "are simple non-driving support wheels.
  • said wheels 3 ', 3" could also, if necessary, be coupled to the driving wheels 8', 8 ".
  • the stability of the machine during work is ensured by stabilizers specially provided for this purpose.
  • These members include a central stabilizer 10 and two lateral stabilizers 13 mounted at the rear end of the machine.
  • the central stabilizer 10 is constituted by an articulated arm provided at its lower part with a shoe 9 resting on the ground.
  • the arm of the central stabilizer 10 is integral with a carriage 12 moving by means of rollers 12 'in the longitudinal members 1', 1 "of the support structure 1.
  • the carriage 12 is preferably hydraulically controlled.
  • central stabilizer 10 can be raised and lowered by means of a hydraulic cylinder 11.
  • the lateral stabilizers 13 are mounted on triangular supports 15, preferably tubular, and are controlled by hydraulic cylinders 14.
  • Figures 6 to 12 show a step of moving the machine.
  • the machine rests on its wheels 3 ′, 3 ", 8 ′, 8" as well as on the central stabilizer 10 and the lateral stabilizers 13.
  • FIG. 7 we start by raising the front wheels 8 ', 8 "as well as the lateral stabilizers 13.
  • the carrier structure 1 of the machine is then moved using the arm 16 of the shovel which bears on the ground (FIG. 8).
  • the carriage 12 and the central stabilizer 10 then remain in the position they originally occupied.
  • the front wheels 8 ', 8 "and the lateral stabilizers 13 are then brought back to the ground (FIG. 9).
  • the central stabilizer 10 Figure 10
  • It is moved with the carriage 12 to the front of the machine ( Figure 11).
  • Figures 15,16 and 17 show a first possibility of maneuver to rotate the machine.
  • the machine rests essentially on the central stabilizer 10 constituting a first fulcrum and on the end of the arm 16 constituting a second fulcrum.
  • the orientation control of the arm 16 is used to rotate the support structure or chassis 1 which comes into alignment with the arm.
  • the wheels 3 ', 3 ", 8.8" and the rear stabilizers 13 are slightly raised (about 10 cm) to allow movement, while being ready to intervene to maintain the balance of the machine.
  • Figures 18, 19 and 20 show a second possibility of maneuvering to rotate the machine.
  • the telescopic arms 7 are first folded and their wheels 8 ', 8 "rest on the ground.
  • the arm 16 of the shovel is positioned to correspond to the axis of the position which the chassis must reach. rotation of the arm is put into action and the wheels 8 ′ and 8 ′′ move accordingly, the telescopic arm 7 of the wheel 8 being unfolded.
  • the 3 'and 3 "wheels are very slightly raised (about 10 cm) to be ready to maintain balance and avoid overhang of the machine.
  • FIG. 13 shows the machine placed on a ditch.
  • the central stabilizer 10 can rest by its shoe 9 on the bottom of the ditch and constitute a secure and resistant point of support. The machine can then work in the vicinity of the ditch without the need to establish an extended track.
  • the machine can easily work in slopes or form uneven and strewn with obstacles.
  • the wheel lift controls allow the wheels to be placed at the desired level and the central stabilizer also constitutes a secure and resistant fulcrum being assisted by the lateral stabilizers.
  • the displacement on hard ground is carried out using two driving wheels 8 ', 8 "independent of each other. It is then necessary that the non-driving wheels 3', 3" and the lateral stabilizers 13 are folded .
  • the machine rests on the two driving wheels 8 ', 8 “and a removable idler wheel 17. To turn the machine (figure 22 and figure 23), the wheel 8" is stopped and the wheel 8 is turned '. The rotation takes place around an axis passing through this wheel and it is acoompag Avenue by the idler wheel 17.
  • Figures 24 and 25 show an alternative embodiment in which the machine is provided with large floats 19 allowing it to move on water bodies.
  • the wheels 8 ′, 8 “must be replaced by shoes 18 and the stabilizers 13 extended.
  • the central stabilizer 10 is articulated on the carriage 12 and consists of two elementary stabilizers 10 i , 10 2 , themselves constituted by an arm provided at its lower part with a support shoe 9 1 , 9 2 resting on the ground.
  • the arms 10 1 , 10 2 are actuated by hydraulic control cylinders 11 1 , 11 2 '
  • the figure shows in line full elementary stabilizers in the folded position. Their support position on the ground is shown in phantom.
  • FIG. 27 represents another exemplary embodiment of the invention in which the elementary central stabilizer 10 is linked by articulation to an elongated central element 20 forming a hollow box.
  • this central box 20 moves a slide 21 linked by articulation to the other elementary central stabilizer 10 2 .
  • the elementary stabilizers are shown coming full in their folded position and in phantom in their support position on the ground.
  • the machine can move easily, by relying on the shoes 9 1 and 9 2 , on relatively hard or uneven ground, for example in mountainous areas, the banks with steep slopes and all obstacles to climb during work.
  • the machine thus equipped can advance without having to involve the boom of an earthmoving member.
  • the central box provided in the embodiment shown in Figure 27 allows the machine to progress in low lift terrain, especially in ponds, canals, rivers, ports, etc.
  • the surface of the box makes it possible to use only very slightly the supporting soil. The box thus avoids damaging the bottom and prevents the piercing of the waterproof layer which often plays an important role.
  • the lateral stabilizers can be omitted.
