Definitions

  • ABSTRACT A tracked vehicle is disclosed with a rotary turret on the vehicle frame; a counterweight is carried by a parallelogram linkage on one side of the frame movable between an extended position engaging a recess in the bottom of the turret to prevent undesired rotation of the turret and counterbalance a load carried by boom means on the diametrically opposite side of the turret.
  • FIG. 3 is a view of the machine already described with reference to FIG. 1, but in a second so-called displacement configuration.
  • FIG. 1 shows a machine which is constituted of a conventional hydraulic shovel, which comprises a frame 1 provided with chines thus improved may be general and is obviously not limited simply to laying pipes as mentioned hereinabove, but is on the contrary advantageous for all works, for which it is desired, with a conventional machine with pivoting turret, to effect a precision handling requiring that the turret be strictly immobilised with respect to the frame as well as a satisfactory equilibrium.
  • the invention proposes such a machine, adapted to the effecting of precision handling works, and constituted by a frame provided with rolling members, by a turret which is mounted to pivot on the frame and to which is coupled an operating equipment and by a device for selectively blocking the pivoting of the turret comprising blocking members coupled to one of the elements, frame or, turret, and complementary members coupled to the other element, turret or frame, said locking and complementary members being able to cooperate in order to prevent the turret from pivoting.
  • this machine comprises a counterweight which is adjustably coupled to one of the two elements, frame or turret, one of the groups of blocking or complementary members being coupled to said counterweight.
  • This counterweight is preferably coupled to oneof the sides of the frame by means of a connection consti ⁇ tuting a deformable quadrilateral, whilst a locking plate is integral with said counterweight, and is capable of v being inserted, when this counterweight is in working position, between the two arms of a stirrupshaped member integral with the turret.
  • a plane of clearance of the working equipment which is substantially perpendicular to the longitudinal axis of the frame, corresponds to the position of blocking of the pivoting of theturret with respect to the frame.
  • FIG. 1 is an elevational view of a machine according to the invention, in its position of precision handling;
  • FIG. 2 is a section along 11-]! of FIG. 1;
  • a turret 3 is mounted to pivot about an axis 4.
  • an operating equipment 5 which comprises, in the present case, a digging bucket 6 is articulated to the turret 3 about an axis 8.
  • a pulley block 9 which comprises a hook 10, from which is suspended a section of pipe 11 by means of a rope 12.
  • the section of pipe 11 is suspended above the trench which was dug in this above-mentioned position, is inserted, with a very small clearance, between the two arms 18 of a stirrup shaped member which is integral with the turret 3, said stirrup in the example shown, fixed to said turret 3 by weld-beads l9.
  • the operating equipment 5 is then disposed in a transverse plane substantially perpendicular to the direction of translation of the endless-tracks 2 and is disposed opposite the counterweight 7 which balances the mass thereof.
  • FIG. 3 shows the same machine, but this time the locking plate 17 is disengaged outside the stirrup.
  • the turret 3 has pivoted so that the operating equipment 5 is disposed in a plane parallel to the direction of translation of the endless tracks 2.
  • the counterweight 7 has been disposed, by deformation of the parallelogram 14, along the turret 3 so that the lateral bulk of said counterweight 7 is very small and practically does not increase that of the shovel itself.
  • the arms 18 of the stirrup could also be integral with the counterweight 7, the locking plate 17 then being integral with the turret 3;
  • the plane of the working equipment 5 could very well have been disposed other than perpendicularly to the direction of translation of the endless tracks; in particular, it could have been chosen to be parallel to said direction, this being an advantageous disposition in certain other works involving the laying of pipes in trenches.
  • a work vehicle having a vehicle frame supported by ground-engaging rolling members, a turret mounted to pivot about a vertical axis on the vehicle frame, work supporting means mounted on said turret and extending outwardly from said turret, a deformable quadrilateral support frame connected on one end to one side of said vehicle frame, a counterweight supported by said quadrilateral support frame, a stirrup carried on the lower portion of said turret comprising two spaced arms, a locking plate integral with said counterweight, said deformable quadrilateral frame being movable between a first or retracted position in which the counterweight is closely adjacent the vehicle frame and an extended position in which said locking plate is engageable with said stirrup between said spaced arms to lock said turret against rotation while simultaneously providing a counterweight function for said vehicle.
