Definitions

  • the invention relates to an operating machine with an articulated arm, displaceable laterally and which has an operating means at the respective end, as power shovels, perforators, mowers etc.
  • an operating machine any excavator with an articulated arm, either tracked or on tires, or mechanical shovels with a back excavator means or others, not excluding the operating machines which are equipped at the end of the arms with perforating points as lawn mowers for parks and gardens etc.
  • the object of the invention is to allow a greater lateral displacement of the excavation in respect to the longitudinal symmetry axis of the excavator and to consent that the excavation is made with a good perpendicularity in any condition.
  • an operating machine with a laterally displaceable articulated arm composed substantially by a cabin arm and forearm, at the end of forearm being placed an operating unit, characterized in that the articulation zone between said cabin arm and said forearm of the articulated arm is equipped with an articulation also on the vertical axis by a simple or double parallelogram system and provided with a dynamic fluid cylinder means in a way to control the respective angles that can be made.
  • Figure 1 represents a schematic view of the excavator seen from above with the articulated arm angled to carry out an excavation in a lateral position to the machine.
  • Figure 2 represents a side view in elevation of the machine of Figure 1 with a first oleodynamic cylinder solution for the vertical command of the forearm.
  • Figure 2A represents an alternative solution in a view similar to Figure 2.
  • Figure 3 represents a side view in elevation of the machine of Figure 1 with a second oleodynamic cylinder solution for the vertical command of the forearm.
  • Figure 4 represents a side view in elevation of the machine of Figure 1 with a third oleodynamic cylinder solution for the vertical command of the forearm.
  • 1 indicates the machine chassis of frame (in the specific case with wheels, but it could can be also tracked ).
  • 3 represents the rotatable cabin frame mounted on said frame by the intermediation of joint bearing according to prior art
  • 4 represents the cabin arm pivoted only on a horizontal axis.
  • 5 represents the forearm pivoted and moved both on horizontal axis by means of the bracket F and on the vertical axis 7.
  • - the pivoting on a horizontal axis of said cabin arm 4 is controlled by the leverism 12.13, 14 with the respective parallelogram pivoting systems G F, E D C, A B in connection with the respective base brackets ( S I S2 ):
  • - the pivoting on the horizontal axis of said forearm 5 is controlled by the oleodynamic cylinder (9) in the three solutions of the Figures 2,3,4, being however preferable the solution of Figure 2 because the cylinder command is enclosed in the forearm, while the other solutions can involve encumber obstacles;
  • - the pivoting on vertical axis 7 is controlled by the oleodynamic cylinder 8.
  • the movement of the shovel 6 is operated according to well known techniques by the oleodynamic cylinder 10.
  • the oleodvnamic cylinder 9 is associated to the parallelogram PI P2 P3 P4 by a pair of delay levers 91 ,92 on the bracket S3 of forearm support 5, similarly to the parallelogram FI F2 F3 F4, made with the pair of intermediate levers 101 and 102 for the orientation of the shovel 6 by the cylinder 10.
  • the operating machine is identified for the fact that the said dynamic fluid cylinder (9) that commands the forearm (5) in respect to the cabin arm (4) is enclosed in an embedding (Pi) that extends over the forearm (5) and beneath a respective dynamic fluid cylinder (10) of orientation of the operating unit (6) and both have an assembly on the respective opposite parallelogram (PI P2 P3 P4 ; FI F2 F3 F4).

Abstract

L'objet de l'invention est une machine de travail équipée d'un bras articulé, déplaçable latéralement, composé substantiellement par un bras (4) et un avant-bras (5) et qui possède à l'extrémité de l'avant-bras (5) une unité de travail (6) avec les caractéristiques suivantes: la zone d'articulation entre ledit bras (4) et ledit avant-bras (5) dudit bras articulé est dotée d'une articulation (7) également sur l'axe vertical grâce à un système de parallélogramme (S1 4 12' S2/A B G F; S1 4 12 13 14 S2/A B C D+C E F G); un dispositif dynamique de vérin hydraulique équipe ladite articulation (8) de manière à contrôler l'angle respectif qui se forme sur l'axe vertical, pour que, lors de la rotation de la structure(3) et du positionnement du bras dans la position angulaire correspondante (4), il s'effectue une rotation contraire dudit avant-bras (5) pour le placer dans une position au moins parallèle (Y) à l'axe de symétrie longitudinal du châssis de la machine dans la direction de l'avance (X).
