Definitions

  • the invention relates to a light rapid intervention truck with excavator excavator of the type comprising a chassis carrying an unobstructed horizontal rear platform, an excavator excavator mounted on a turret with total rotation through 360 ° relative to the chassis and consisting of a boom carrying and maneuvering a bucket, said excavator being able to be moved between a working position where it is deployed towards the rear of the truck overhanging relative to the latter and a rest position where it is folded towards the front on the truck.
  • the subject of the present invention is such a light rapid intervention truck, the dimensions of which are reduced to the maximum, so that it can be air-transportable while having a maximum working radius or range, when the excavator is deployed. .
  • the boom is formed by at least three arms articulated one on the other, the turret is mounted lowered in an intermediate chassis fixed to the main chassis of the truck and two of the three articulated arms of short range, located at the ends of the boom are connected one to the shovel bucket and the other to the turret, while the intermediate arm is of a greater length corresponding approximately to the length of the platform shape of the truck, the arms and the bucket being able to pivot with respect to each other under the action of four double-acting cylinders, said arms taking, when the boom is in the folded state, reciprocal positions delimiting a triangle isosceles oriented downward and whose side of the base formed by the intermediate arm is slightly inclined relative to the horizontal at a level corresponding to the height of the ceiling of the truck cabin.
  • the different arms consist of two parallel flat bars in the shape of an isosceles triangle of low height, connected transversely, in particular by welding, by tubular spacer members, which also serve as fixing members to the jacks.
  • FIG. 1 shows a schematic perspective view of the vehicle consisting of a light truck 1 and an excavator, or backhoe 2.
  • the truck 1 comprises a chassis 3 mounted on four wheels 4 and carrying a cabin 5, a motor 6 disposed at the front, a hydraulic tank 7, a spare wheel 8 and a rear platform 9.
  • the shovel 2 shown in the deployed working state in this figure, essentially consists of a turret 10 which can rotate at an angle of 360 °, on an invisible support mounted in the chassis 3 of the vehicle, with an arrow formed of three arms 11, 12, 13, articulated between them, and of a bucket 14.
  • the arm 11 can be raised or folded down by jacks 15 fixed to lateral uprights 16 of the turret, while jacks 17, 18 , 19 are used to maneuver the corresponding arms 12, 13 and the shovel 14.
  • a work station 20 is arranged laterally on the platform 9 of the vehicle next to the turret 10 of the excavator 2, and groups together all of the controls for the various jacks and of a hydraulic motor - not visible in this figure. - controlling the rotation of the turret.
  • the vehicle is equipped with four lateral stabilizers 21 each formed by a stand 22 articulated on the chassis 3 and whose base is provided with a support pad 23 also articulated on the stand.
  • Figure 2 shows a schematic side elevational view of the entire vehicle 1 and the shovel 2 in the folded or retracted state (rest position) on the platform 9 of the vehicle.
  • the boom with three arms 11, 12, 13, of the shovel 2 can be retracted above the platform to occupy a space corresponding approximately to the overall height of the vehicle and the overall length of the latter's platform.
  • the boom 2 consists of three arms, 11, 12, 13, articulated together in axes 122, 123 and of which two 13 and 11, of short range, located at the ends of the boom are connected, l 'one 13 to the bucket 14 of the shovel, and the other 11, to the uprights 16 of the turret 10, while the intermediate arm 12 is of a greater length corresponding approximately to the length of the platform 9 of the vehicle .
  • the arms 11, 12, 13 and the bucket 14 can pivot with respect to each other under the action of the four double-acting cylinders already mentioned, 15, 17, 18, 19, and take - when the arrow 2 is at the folded state and brought back by rotation in the median plane of the vehicle and above the platform - reciprocal positions delimiting approximately an isosceles triangle, oriented point downwards and whose side of the base (arm 12) is slightly inclined with respect to the horizontal at a level corresponding to the height of the ceiling of the cabin 5 of the vehicle 1.
  • the different arms 11, 12, 13, are constituted, like for example the arm 12, by two parallel flat bars in the shape of an isosceles triangle of low height, connected transversely, in particular by welding, by tubular members forming spacers 24, one of which also serves as a member for fixing to the working cylinder 18 of the bucket operating arm 13, and the other of which serves as a member for fixing the cylinder 17 for actuating the intermediate arm.
  • the turret 10 is fixed to a lower ring 25 of the type with alternating rollers, in engagement with a pinion 26 integral with the axis of a hydraulic drive motor 27 housed in the lowered position in the chassis 3 of the vehicle and at inside an intermediate frame 28 supporting the crown 25 and the turret 10, and fixed by bolting in the frame 3.
  • the work station 20 is partially hidden by the turret 10.
  • a pump 29 connected to the hydraulic tank 7, said pump also being connected to a power take-off, not shown, on the engine of the vehicle.
  • hydraulic motor 27 and the various jacks 15, 17, 18, 19 are connected to a conventional hydraulic system, not shown, including the pump 29 and the tank 7 as well as a distributor supplying the hydraulic motor 26 and the cylinders.
  • the vehicle is provided with lateral stabilizers 21 formed of crutches 22 of triangular shape, equipped with articulated rectangular pads 23 and which are pivotally mounted on a transverse upright 30 of the vehicle chassis.
  • Each stabilizer is rotatably mounted on an axis 31 such that in the raised or at rest state (FIGS. 2 and 3B), said crutches 22 are arranged vertically inside the space corresponding to the overall limits of the vehicle. 1.
  • crutches 22 are actuated by jacks 32, the body of which is integral with the upright 30 and the rod of which is articulated at a point 33 offset relative to the pivot axis of said crutches.
  • the stabilizers have the effect of increasing the earth-moving performance, which could otherwise be reduced by the light weight of the vehicle and the stands 22 can also be deliberately blocked in the semi-open or retracted position, if the configuration of the land requires it.
  • FIG. 3B shows this state in which the vehicle 1 provided with the shovel 2 is transported in an airplane, identified by its inner shell 34.
  • the jacks 31 are conventionally connected to the entire hydraulic system of the vehicle.
  • the arrangement of the work station 20 next to the turret 10 on the platform 9 of the vehicle brings together all the controls and allows excellent visibility of the site.
  • FIG. 4 the rear evolution zone of the shovel 2 is reproduced at the rear of the vehicle 1, stabilized on a ground 35, which is capable of digging excavations having the outline 36 in section.
  • the shovel 2 can have a total rotation (360 °), it can carry out work all around the vehicle and therefore have a very large working radius, which reduces the downtime usually due to the movement of the vehicle when digging large cavities.
  • the operation of the assembly is as follows: once arrived at the site, the driver of the vehicle 1 places the lateral stabilizers 21 in the required position, then maneuvers the shovel 2 in a conventional manner using the jacks 15, 17, 18 , 19.
  • the excavation retracts (or folds) the boom formed by the arms and the bucket in the position corresponding to fig. 2, (the arms being articulated together at 122 and 123 (see FIG. 2) so that, folded, they occupy a space in the shape of an inverted triangle), but still in a cantilevered position at the rear or on the side of the vehicle, then it rotates the turret by the desired angle to bring the assembly of boom 2 in the vertical median plane below the platform.
