Definitions

  • the invention relates to the technical sector of the means of handling and working tools carried by a vehicle, in particular, but not exclusively, in the agricultural field or in the field of public works.
  • these sets can be fixedly mounted on the rear or front of carrier vehicles or in an articulated way.
  • these assemblies can be arranged in the center line of the vehicle or offset from it.
  • the pivot axis of the assembly is secured to a toothed pinion which cooperates with a rack displaceable in translation by means of a jack to cause, a concomitantly, the rotational drive of the whole.
  • US patent 4,419,040 discloses a drive device in rotation of a pivotally mounted assembly at the rear of a tractor and subject to two cylinders to allow rotational scanning. It appears that the stems cylinders are not articulated together on a common part, so that it does not seem possible to obtain, from the axis of symmetry and from pivoting, rotation greater than 90 °.
  • the teaching of this patent essentially corresponds to the characteristics falling under the first part of claim 1.
  • the object of the invention is to remedy these drawbacks, simple, safe, efficient and rational way.
  • the problem which the invention proposes to solve is to be able ensure a pivoting of the assembly according to a total rotation of at least 180 °, which is important for some applications, as it is by example the case for pious pushes.
  • the axes of articulation of the actuating members and of the assembly are arranged according to the vertices of an isosceles triangle.
  • the rods of the jacks are arranged under the pivot axis of the assembly. Rotational drive takes place in a horizontal plane.
  • the characteristics of the invention find a particularly advantageous application in the case where the device is coupled to a carrier vehicle, in order to work either right or left of the vehicle, considering its direction of travel.
  • the assembly is designated by (E).
  • the set (E) can be an integral part of a pile driver of any known and appropriate type, without excluding other devices likely to fulfill specific functions.
  • This set (E) is mounted with capacity of articulation, in particular in a horizontal plane with respect to a pivot axis (A) integral with a fixed part (B).
  • this fixed part (B) can be coupled to the three-point lift system on a vehicle tractor-type carrier.
  • the fixed part (B) which receives, with free rotation, the assembly (E), has arrangements (C and D) for mounting with articulation capacity of two actuating members (1 and 2).
  • the arrangements (C and D) are arranged on either side of the fixed part (B) receiving the pivot axis (A).
  • these arrangements (C and D) consist of support soles arranged in a horizontal plane, or substantially horizontal, and integral with the fixed part (B) in the form of example of a vertical beam.
  • the actuators (1 and 2) consist of two cylinders including the barrels (la and 2a) are articulated on the support parts (C and D) of the fixed part (B).
  • the rods (1b and 2b) of the jacks (1 and 2) are connected in an articulated manner, at a common part (F) presented by the mobile assembly (E).
  • the pivot and rotation axis (A) of the articulated assembly (E) is arranged along the axis of symmetry (X - X ') of the articulation arrangements (3 and 4) cylinders (1 and 2) respectively on their respective support (C and D).
  • the hinge pins (3 and 4) are arranged in an alignment perpendicular to the aforementioned axis of symmetry (X - X ').
  • the axes of articulation (3, 4 and A) are arranged according to the vertices of a triangle isosceles, the articulation pivot (A) therefore being arranged at the angle at the top of this fictitious triangle.
  • the common articulation part (F) of the two jack rods (1b - 2b) is constituted by a nut (5) coupled at the end of the rod (2b) of the jack (2), and mounted in a yoke (6) coupled to the end of the rod (1b) of the jack (1).
  • the joint joint (F) and therefore the two rods (1b and 2b) of the cylinders (1 and 2) are located under the axis of pivot (A) and under the articulated assembly (E).
  • the whole (E) pivots in a horizontal plane located above the plane defined by the rods (1b and 2b) articulated in (F).
  • the two cylinders (1 and 2) are of the double-acting type and are connected to the barrel level (1a and 2a), to a double-acting hydraulic distributor (7) whether or not in combination with a double non-return valve (8) so that the assembly is self-locked at rest.
  • rod side supply, cylinder (1) corresponds to barrel side supply, cylinder (2) and vice versa.
  • the rotational drive device finds many applications. Illustrated in the figures of the drawings, an example application of the device to a pile driver.
  • the set (E) can be constituted by a vertical beam whose base receives, with capacity articulation, the barrel of a jack (9) whose rod is connected to an articulated arm in end of said beam and receiving, at the end, a vertical oscillating arm equipped of arrangements capable of ensuring, in a known manner, guided movement a mass to allow the driving of the piles.
