Definitions

  • the present invention relates to an improvement made to public works machines comprising a self-propelled chassis on which is mounted a turret carrying work equipment.
  • It relates more particularly to an improvement made to the machines of the type subject of FR-A-2 532 671 and whose work equipment has a structure such that it makes it possible to work either as a loader or excavator by simple change of work tool.
  • Figure 1 attached schematically illustrates the general structure of such a machine used as an excavator.
  • the work equipment designated by the general reference (1), is composed of four articulated and angularly deployable elements relative to each other, namely an arrow (2), a spout arrow (3), an arm (4) at the end of which is mounted the tool consisting of a bucket (5).
  • This equipment is mounted on a turret (6) carried by a conventional vehicle preferably comprising a frame articulated in two parts, the engine being mounted on the rear chassis and the driving position and the work equipment (1) being , meanwhile, mounted side by side on the turret (6) associated with the front chassis.
  • the various elements of the equipment are interconnected by an articulation allowing their angular positioning to be modified with respect to each other around horizontal pivot axes, the displacement being obtained by means of jacks.
  • the boom (2) is articulated relative to the turret (6) and its position is adjusted by the boom cylinder (7) by means of two arms (8,9).
  • the arrow spout (3) is connected to the other end (10) of the arrow (2) and the angular position ⁇ of these two elements (2,3) is adjusted by means of the jack (11) called “jack of arrowhead ".
  • the arm (4) is articulated at the end (12) of the arrow spout (3) and the angle ⁇ between these two elements is adjusted by means of a third cylinder (13) called “cylinder of arms ".
  • the bucket (5) is mounted at the end (17) of the arm (4) and its position is adjusted by a fourth cylinder (15) called "bucket cylinder".
  • control of the various cylinders can be either individual, or possibly carried out in accordance with the teachings of application PCT / FR 95/01286.
  • the tool (5) is therefore moved in space on the one hand by modifying the positioning of the various elements forming the work equipment (1) by pivoting about a horizontal axis of the joint. connecting the elements together and to the carrier, and, on the other hand, by rotation of the turret (6) which makes it possible to work as well in the axis of the vehicle, as on both sides of the latter at any angle.
  • Such a type of machine is therefore designed to allow work to be carried out while keeping the various elements of the work equipment in line with one another, in the same vertical plane, the axes of articulation being parallel to the ground. and between them.
  • a structure poses problems when it is desired to work offset, a possibility which has been obtained to date by mounting the arm jack (13) by means of cardan joints.
  • the arm jack (13) poses problems, since this causes the cylinder to rotate and consequently wear out.
  • the cylinder forms an angle relative to the element it controls, which results in a decrease in its efficiency.
  • the device according to the invention is characterized in that at least the tool-carrying arm is connected to the element which precedes it by means of a double articulation allowing on the one hand an angular displacement around a horizontal axis , and, on the other hand, a lateral angular displacement around an axis passing in a plane orthogonal to the horizontal pivot axis, the control of this lateral displacement being obtained by means of a jack mounted laterally with respect to to the support element and which causes the pivoting of the double articulation, the jack controlling the angular movement around a horizontal axis of the tool-carrying arm, for its part, bearing on this articulation in front of the pivoting axis lateral.
  • the double articulation according to the invention is at least between the arrow spout and the tool arm, the articulation between the end of the arrow and that of the arrow spout can be simple.
  • the two articulations provided at each end of the arrow spout will be produced in accordance with the invention so as to be able to carry out a double offset.
  • the machine according to the invention therefore comprises work equipment (1) composed of four angularly articulated elements, deployable with respect to each other, namely a boom (2), a boom spout (3), an arm (4) at the end of which is mounted the tool consisting of a bucket (5) .
  • This equipment is mounted on a turret (6) carried by a conventional vehicle.
  • the boom (2) is articulated with respect to the turret (6) and its position is adjusted by the boom cylinder (7) by means of two arms (8,9).
  • the boom spout (3) is connected to the end (10) of the boom (2) and the angular position ⁇ of these two elements (2,3) is adjusted by means of the boom spout cylinder (11).
  • the arm (4) is articulated at the end (12) of the arrow spout (3) and the angle ⁇ between these two elements is adjusted by means of a third jack (13).
  • the bucket (5) is mounted at the end (14) of the arm (4) and its position is adjusted by a fourth cylinder (15) called "bucket cylinder".
  • At least the arm (4) is connected to the element which precedes it, therefore in the present case to the arrow spout (3) by means of a double articulation designated by the general reference ( 20) and which allows on the one hand, the angular displacement around the horizontal axis A, and, on the other hand, a lateral angular displacement around an axis B passing in a plane orthogonal to the horizontal pivot axis AT.
  • the work equipment is preferably designed as illustrated in Figures 3 to 6 so that the connection between the end (10) of the arrow (2) and the end of the arrow spout (3) is made in a similar manner.
  • the control of the lateral displacement is obtained by means of a jack (22) mounted laterally with respect to the jib spout (3) and which acts on the double articulation.
  • the jacks (11,13) controlling the angular displacements around the horizontal axes A take, for their part, support on the double articulation (20) in front of the lateral pivot axis B, which allows an action in line even during a work in offset.
  • the solution according to the invention has very many advantages among which we can cite in particular, when the machine allows to carry out a double offset, to have an additional angular position for the tool (6) making it possible to bypass obstacles.
