Definitions

  • the axis of pivoting of the manipulation arm relative to the support frame is placed near the underside of the complementary boom, which results in the possibility of pivoting of the manipulation arm, at from the configuration of the complementary boom in which the handling arm is placed in the extension of the support frame, only downwards.
  • the only boom folding configurations complementary are similar to that shown in Figure 2 of the aforementioned European document, in which the first pivot axis can not be placed vertical. Therefore, the pivoting of the complementary boom in its folding configuration, around said first pivot axis, requires a large force, necessarily mechanized, for example that of powerful jacks.
  • the invention in the context of a handling boom having the constitution defined in the preamble of claim 1, aims to allow the configuration of the folding boom configuration and the verticality of the first pivot axis to be reduced, in order to reduce the force necessary to pivot the complementary boom, folded back, around the first pivot axis, substantially only to the force making it possible to overcome the friction of said pivoting.
  • the second pivot axis is arranged as specified in the characterizing part of claim 1.
  • the main advantage of a boom according to the invention lies both in its ease of use and in a greater lightness of manufacture.
  • the handling arm 4 and the support frame 2 constitute a complementary arrow 2-4, in two parts articulated around the pivot axis 5 contained substantially in the upper face S 2/4 of said complementary arrow in its deployment configuration (Figure 2B).
  • This position of the pivot axis 5 makes it possible to pivot upwards (FIG. 3B) of the handling arm 4 relative to the support frame 2, from the configuration of FIG. 2B.
  • the main boom 1 is substantially horizontal.
  • the pivot axis 3 is vertical, while the pivot axis 5 is horizontal, transverse with respect to the main general direction D1 parallel to which extends the main boom 1.
  • the handling arm 4 is oriented upwards, its free end 4A being placed in front of the pivot axis 5 so that the center of gravity G of the assembly of the support frame 2 and of the complementary arrow 4 is placed on a vertical V close to the pivot axis 3.
  • the complementary general direction D4 of the manipulation arm 4 is parallel to the main direction D1, the manipulation arm 4 being oriented towards the rear. 1A of the main boom 1.
  • the complementary boom constituted by the assembly of the support frame 2 and of the handling arm 4 is placed along the main boom 1, in configuration out of service, the length of the assembly being limited to the length L1 of the main boom 1.
  • the general direction D2 of the support frame is parallel to the main direction D1.
  • the support frame 2 has pivoted by approximately 180 ° around the vertical pivot axis 3 and its general direction is again parallel to that D1 of the main boom 1 and substantially merged with it, the support frame 2 being placed in the extension of the main boom 1, in front of the front end 1B of this main boom.
  • FIGS. 5A, 5B the directions D1, D2, D4 are horizontal and parallel.
  • the handling arm 4 has been replaced in the extension of the support frame 2, after pivoting around the horizontal axis 5.
  • the deployment configuration of the complementary boom (2-4) is again obtained.
  • the total length LT of the equipment is equal to the sum of the lengths of the main boom 1 and of the complementary boom constituted by the support frame 2 and the manipulation arm 4. This is the service configuration of the complementary arrow (2-4).
  • the vertical V on which the center of gravity G is disposed has moved over a circle C of radius R centered on the axis of pivoting 3.
  • the radius R is small, less than 1 m, whereas previously, when the handling arm 4 had to be moved while remaining horizontal, the radius R could in some arrows, exceed 10 m.
  • FIGS. 2C and 3C show the complementary arrow, seen from the side, in the configurations of FIGS. 2B and 3B, respectively, as well as the jack 6 for controlling the pivoting around the axis 5.
  • Figures 3D and 4C show the complementary arrow, seen from above, in the configurations of Figures 3A and 4A, respectively, as well as the device for controlling the pivoting of the support frame 2 around the vertical pivot axis 3.
  • the end 2B of the support frame 2, near which the pivot axis 5 of the handling arm 4 is disposed on said support frame, is located behind the front face 1B of the main boom 1 in the configuration of Figure 3D, and in front of this front face 1B in the configuration of Figure 4C.
  • the spindle 13 is arranged parallel to the pivot axis 3 of the support frame 2 with respect to the main boom 1 and is constituted by two half-shafts 15 integral with the pistons 16 of two opposite jacks and capable of entering the eyes 17 formed at the front end 1B of the main boom 1 and 18 formed in the support frame 2.
  • the jacks have a common chamber 19, which is connected to a conduit 20 and which, when supplied with pressurized fluid, causes the output of the half-shafts 15 and their introduction into the eyes 17 and 18, when these are opposite one another (FIGS. 4A, 4C).
  • Each actuator also has a chamber 21, opposite the chamber 19, the two chambers 21 being connected by a conduit 22, itself connected to a conduit 23.
  • the spindle 14 is arranged parallel to the pivot axis 5 of the handling arm 4 relative to the support frame 2 and is constituted by two half-shafts 24 integral with the pistons 25 of two opposite jacks and capable of entering the eyes 26 formed at the end 2B of the support frame and 27 formed in the manipulation arm 4.
  • the jacks have a common chamber 28, which is connected to a conduit 29 and which, when supplied with pressurized fluid, causes the output of the half-shafts 24 and their introduction into the eyes 26 and 27, when these are opposite one another (FIGS. 5B, 2B).
  • Each actuator also has a chamber 30, opposite the chamber 28, the two chambers 30 being connected by a conduit 31, itself connected to a conduit 32.
  • FIGS. 9 to 11 has a constitution identical to the handling arrow of FIG. 1, to which a supplement has been added.
  • This variant therefore comprises a main boom 1, telescopic, a complementary boom 2-4, itself comprising the support frame 2 pivotally mounted on the main boom 1 around the pivot axis 3, and, a handling arm 4 pivotally mounted on the support frame 2 around the pivot axis 5, all this having the characteristics already defined with reference to the preceding figures 1 to 8.
  • two supports 62 of the manipulation arm 4 extend laterally on one side of the main boom 1, having their upper faces 63 located substantially in the extension of the face 64 of the main boom 1, which constitutes the lower face. of said main boom when the latter is substantially horizontal.
  • the manipulation arm 4 can be supported by these supports 62, their width being sufficient to receive said handling arm.
  • the upper face 63 of each support 62 is delimited by two oblique edges 66 for holding the handling arm 4 in position for wedging on the supports 62.
  • each support is shaped into two plates 67 between which an upright 68 which comprises the manipulation arm 4 is capable of being disposed, each plate 67 comprising an eye 69 for receiving a removable rod 70 preventing the amount of upright 68 from leaving the two plates 67 between which it is capable of being received.
  • the handling jibs described above each have a main telescopic jib 1 associated with a complementary jib 2-4 and constitute the handling equipment for mobile cranes. If the particular structure solves well the problems of size and weight of a mobile crane equipped with a telescopic main boom, it must however be observed that such a structure can be adopted in the production of fixed cranes and that the boom main may be other than telescopic: the structural advantages are effectively appreciable and sought after whatever the type of crane and / or main boom on which the complementary boom 2-4 is mounted.
  • the originality of the invention lies in obtaining an R2 / R4 ratio of less than about 0.20 between the dimensions, measured in a horizontal plane (plane of FIGS. 2A; 3A), of the complementary jib 2-4 between its folding configuration (R2, FIG. 3A) and its deployment configuration (R4, FIG. 2A), the maximum overall dimensions being able to not exceed that of the crane itself.
