Definitions

  • Object of the present invention is a multi-use mobile elevator-excavator.
  • the said invention proposes to perform differing tasks and functions which are at present performed by separate machines, thus uniting the said tasks in a single machine.
  • the said machine apart from the typical task of an elevator, which must permit lifting, moving and stacking of heavy loads at height and necessitating long reach, the said machine having at the same time a contained mass so as to be able to be manoeuvrable inside superiorly and laterally closed stacking areas, the present machine can be used also as a loading shovel and excavator.
  • the prior art teaches machines which have attempted to unite the three above-mentioned functions. Some of the said machines envisage the possibility of mounting a loading shovel or an excavator to the end of a telescopic arm of the type used for lifting trucks.
  • the resulting realisations are however not highly functional and are characterised by numerous limitations. For example, in those prior art realisations in which the excavator is applied to the top of the telescopic arm, thanks to the structure of the connection used grave operational limitations are manifested with reference to the lateral operational capacity as well as the ability to work at a certain distance below ground level.
  • the present invention proposes to obviate the drawbacks and lacks of the prior art by providing a multi-use elevator-excavator equipped with a single arm which arm is structured and articulated in order to perform all the movements necessary for the various tasks (elevator, loader, excavator) with specific tools which can be mounted and dismounted to and from the end of the said arm by means of a rapid on-off attachment.
  • 1 denotes a frame mounted on wheels 2 above which a platform 3 is rotatably constrained about a vertical axis.
  • a cabin 22 is laterally housed, by the side of which cabin 22 a first, telescopically extensible manoeuvring arm 4 operates.
  • the said manoeuvring arm 4 is pivoted at is lower end and by means of a horizontal-axis pivot 23 to sustaining means solid with the platform 3 and is activated to rotate in the two directions about the said horizontal-axis pivot 23 by means of a hydraulic jack 24.
  • the manoeuvring arm 4 is rotatably mobile about the pivot 23 in a median plane of the platform 3 and is composed of a first segment 41, internally to which a further segment 42 is slidabiy coaxially housed.
  • a hydraulic cylinder not represented in the figures, produces the axial sliding motion of the segment 42 with respect to the first segment 41.
  • the first segment 51 of a further telescopically extensible arm 5 is pivoted by means of a pivot 6 having its axis perpendicular to the individual direction of the manoeuvring arm 4 axis.
  • the arm 5 exhibits a second segment 52 which is axially slidably coupled to the said first segment 51, the said second segment 52 being slidable in both directions with respect to the first segment 51 by operation of a hydraulic cylinder 26.
  • the longitudinal axis of the arm 5 forms together with the pivot 6 axis a breadth angle which makes possible a horizontal positioning of the arm 5 when the manoeuvring arm 4 is in a completely raised position with regard to the platform 3 and when the said platform 3 is completely horizontal.
  • the segment 42 call be secured rigidly to the first segment 41 in a plurality of positions by means of a pair of opposite mobile pistons 43 equipped with shaped heads 44 able to couple with corresponding hollow seatings 46 arranged laterally on the said segment 42.
  • each piston 43 is part of a single-action hydraulic cylinder 45 which is solidly constrained on the first segment 41 and located with its axis perpendicular to the axis of the said first segment 41.
  • the end or shaped head 44 of the piston 43 is turned towards the inside of the first segment 41 and exhibits a rounded form constituted by a portion of spherical surface which has the same radius as the spherical surface of the hollow seatings 46 arranged laterally on the segment 42.
  • a rapid on-off attachment organ 7 is located which is predisposed to permit of mounting tools such as fork groups 18, shovels 19 or excavator arms 14.
  • the attachment organ 7 comprises a body 8 which is hinged to the end of the second segment 52 by means of a pivot 56 having its axis perpendicular to the arm 5 axis and to the direction specified by the pivot 6 axis.
  • the body 8 is activated and commanded to rotate about the pivot 56 by a hydraulic cylinder 9 operating between said body 8 and the second segment 52.
  • Two identical fixed centring cones 10 are arranged superiorly on the body 8, with parallel axes contained in a single plane parallel to the pivot 56 axis.
  • two mobile centring cones 11 are arranged, which are coaligned and located symmetrically with respect to a vertical median plane of the body 8 perpendicular to the pivot 56 axis.
  • the two mobile centring cones 11 exhibit their common axis parallel to the pivot 56 axis and are guided and commanded to slide axially and symmetrically with respect to the median plane of symmetry perpendicular to the common axis.
  • Each mobile centring cone 11 is fixed to a mobile piston 12 coaxially internally to a small hydraulic cylinder 13.
  • Two hydraulic cylinders 13 are symmetrically opposed and communicating to form a single chamber.
  • the backward stroke of the mobile centring cones 11 is realised by means of the springs 27 operating on the mobile pistons 12.
  • the fixed centring cones 10 and mobile centring cones 11 are envisaged to couple in corresponding hollow conical seatings 20 and 21 predisposed on corresponding attachment organs 17 with which the said tools are equipped, said tools being the excavator arm 14, the fork group 18 and the shovel 19.
  • the arrangement of the fixed centring cones 10 and the mobile centring cones 11 of the attachment organ 7 and of the corresponding hollow conical seatings 20 and 21 is realised in such a way that a perfect alignment of the mobile centring cones 11 axis and the corresponding hollow seating 21 axis is not reached until the two fixed centring cones 10 are perfectly coupled with the corresponding hollow conical seatings 20.
  • a shovel 19 and an excavator arm 14 By means of the rapid on-off device 7 a fork group 18, a shovel 19 and an excavator arm 14, all of known and usual type, can be fixed solidly to the end of the arm 5 by a very fast manoeuvre: the said excavator arm 14 may have pivoted to its end a bucket, or shovel 15, activated hydraulically by means of a hydraulic cylinder 16.
  • the possibility of coupling the excavator arm 14 to the end of the arm 5 permits of endowing the machine with a considerable operative capacity deriving from the particular arrangement and combination and articulation relative to the various arms. It permits, on the one hand, of operating the bucket at a greater depth with respect to ground level, having a longer reach, and on the other hand of operating extremely well in restricted spaces. It is possible, thanks to the several positioning possibilities permitted by the articulation about the pivot 6, to work with the excavator arm 14 on any level parallel to the longitudinal median plane of the vehicle containing the rotation axis of the platform 3 with respect to the frame 1 .
