Definitions

  • This invention refers to a linkage system for making an equipment translate parallely to itself, such equipment being carried by an exacavator or by a basic machine. More specifically the invention refers to an articulated parallelogram linkage system connecting drilling and other similar equipments with the machine carrying them.
  • the mast of the equipment is known to be connected with the machine by means of an articulated linkage system which makes it translate, keeping the equipment consistently parallel to its own original position.
  • linkages usually consist of bars, frames and pistons combined in such a way as to keep a constant parallelism of the equipment while the geometry of the linkage changes during the various movements of the equipment.
  • Another drawback can be the fact that such a connection can alter the properties of the frame on which it is welded, making it weaker or at least making the original structure less reliable as a whole.
  • the purpose of this invention is to obviate the above mentioned drawbacks by proposing a linkage system allowing to keep the structure of new or existing multi-purpose commercial machines unvaried, as two hinging points are sufficient to carry the equipment.
  • this invention proposes to realize a linkage system connecting an equipment and an excavator or a basic machine by which such linkage is carried, characterized in that the linkage is quadrilateral so as to translate said equipment parallely to itself; the linkage consisting of at least one rigid connecting element between the machine and the equipment and at least one piston-like actuating element for said rigid element; the elements forming the linkage system or part of them being connected with the machine along no more than two separate and substantially parallel hinge axles.
  • a basic machine 10 carries a drilling equipment generally indicated by 11, which is moreover connected to the basic machine 10 by means of a linkage 12 that allows the equipment 11 to translate parallely to itself, as shown clearly by the figures.
  • Linkage 12 consists of a rigid boom 13, a rigid bar 14 and a piston 15. Boom 13 and bar 14 are hinged respectively in 16 and 17 to a frame 18, which in turn is hinged in 19 to the mast of equipment 11.
  • Stem 21 of piston 15 is hinged in an intermediate point 20 of boom 13.
  • boom 13 is hinged in 22 to the basic machine 10, while bar 14 and piston 15 are hinged along one hinge axle 23 to the same machine 10.
  • FIG. 2 A preferential but not limitative configuration of this hinging system is shown by fig. 2, consisting of two side-mounted bars 14, rigidly joined by a cross-member 24 with respective fork-extensions 25. These have their ends connected to flanges 26 of the machine 10 and to lugs 27 of two side-mounted pistons 15 that pivot on the same shaft through pins 23.
  • actuators 40 and 15 of fig. 5 are series connected through an incompressible fluid in such a way that if an actuator , for example 40, is expanded, the second actuator 15 is automatically forced by the first one to expand too, thus generating the parallel motion.
  • the pivoting points of unit 12 to machine 10 are realized only along two horizontal axles 22 and 23, which, in the case of an existing machine such as a commercial excavator , are the hinging points provided for the attachment of the equipment that can be mounted on the machine. Consequently, the machine does not require any supplementary adapting parts, such as brackets to be welded on for extra hinge axles.
