Definitions

  • the present invention relates to the technical field of maritime cranes, and in particular that of knuckle-boom cranes for offshore application.
  • such an articulated arrow conventionally comprises two successive arrows: a support arrow and a terminal arrow.
  • the support boom (commonly called “main boom” in English) is conventionally articulated on a support structure.
  • the terminal arrow (commonly called “jib” in English) is itself conventionally articulated on the support arrow.
  • the second cylinders are conventionally installed between the facing faces of the two parts of the articulated boom: the upstream end of the cylinder is secured to the main boom and the downstream end of the rod is secured to the articulated boom .
  • the support structure and the upstream end of the main boom cooperate via upstream articulation means defining an upstream articulation axis.
  • downstream end of the main boom and the upstream end of the terminal boom cooperate via downstream articulation means defining a downstream articulation axis.
  • the upstream and downstream articulation axes advantageously extend parallel to one another.
  • said at least downstream linear actuator is secured with, on the one hand, one of the side faces of the support arm and, on the other hand, one of the side faces of said terminal boom.
  • Said at least downstream linear actuator is secured to one of the side faces of said main boom by means of upstream assembly means in the form of a cardan joint, and one of the side faces of said terminal boom by means of downstream assembly means in the form of a ball joint (the "ball" function of the cardan joint releases rotations and eliminates parasitic moments, in particular parasitic bending moments).
  • Such a configuration has the particular advantage of conferring an improved lever arm between the main boom and the terminal boom.
  • This new design also makes it possible to increase the articulation angle between the articulated boom parts.
  • downstream linear actuator also makes it possible to improve the capacity of the articulated boom to support a load in a given position, in particular when the downstream linear actuator is completely retracted or completely extended.
  • the upstream assembly means comprise a spider carrying said at least one downstream linear actuator, and at least one fork, carrying said spider and assembled with the side face of said main jib.
  • the present invention also relates to a machine for offshore application, equipped with an articulated jib crane according to the invention.
  • articulated jib crane 1 (also called “grue 1”, or “knuckle boom crane” in English) is suitable for offshore applications.
  • Such an articulated jib crane 1 is advantageously designed to equip a machine for offshore application (not shown - also called “offshore machine”). This crane 1 is thus adapted to be embarked on the “offshore” machine.
  • engine encompasses in particular marine engines, in particular ships, pontoon cranes, barges and offshore platforms.
  • This crane 1 is thus useful, without being limiting, for the installation or dismantling of transport infrastructures, repairs or operations on board.
  • the support structure 2 advantageously consists of a shaft or mast, intended to be rotated about a vertical longitudinal axis 2' by means of maneuvering means (not shown, advantageously hydraulic or electric).
  • the winch drum 7 and the rotation drive means 8 together form a winch, advantageously conventional in itself.
  • the rotation drive means 8 are chosen in particular from electric or hydraulic motor means.
  • the articulated jib 3 is advantageously equipped with pulleys 9, which are dimensioned, distributed and arranged in order, to guide the elongated lifting member L between the winch drum 7 and the load to be lifted (not shown).
  • the main 31 and terminal 32 arrows thus advantageously have a generally parallelepipedal shape.
  • the side faces 311, 321 advantageously extend parallel (or approximately parallel) with respect to each other, preferably vertically.
  • the upstream end 312 of the main boom 31 is assembled with the support structure 2.
  • the downstream end 313 of the main boom 31 and the upstream end 322 of the terminal boom 32 are assembled together. And the downstream end 323 of the terminal arrow 32 is free.
  • the support structure 2 and the upstream end 312 of the main jib 31 cooperate via upstream articulation means 35 defining an upstream articulation axis 35', advantageously horizontal.
  • the main jib 31 is intended to be maneuvered in rotation relative to the support structure 2, around this upstream hinge pin 35' located at its upstream end 312.
  • downstream end 313 of the main boom 31 and the upstream end 322 of the terminal boom 32 cooperate for their part by means of downstream articulation means 36 defining a downstream articulation axis 36', advantageously horizontal.
  • terminal jib 32 is intended to be maneuvered in rotation relative to the main jib 31, around the downstream hinge pin 36' located at its upstream end 322.
  • the upstream 35 and downstream 36 articulation means advantageously consist of articulations, for example in the form of rolling bearings, which are provided between the assembled ends (for example of the bearing/trunnion type).
  • the upstream 35' and downstream 36' hinge axes extend parallel to one another, advantageously horizontally.
  • the various rotational movements of the jib parts 31, 32 are executed by the maneuvering means 5 advantageously associated with control means (not shown).
  • the linear actuators 51, 52 advantageously consist of hydraulic cylinders, preferably associated with a hydraulic unit (not shown).
  • the linear actuators 51, 52 can also consist of electric actuators.
  • Each linear actuator 51, 52 advantageously comprises a cylinder 511, 521 and a rod 512, 522.
  • the rod 512, 522 has a free downstream end 512b, 522b.
  • said at least one downstream linear actuator 52 is part of a cylindrical space E52 (also called maximum horizontal width).
  • cylindrical size is meant in particular the outer volume defined by said at least one downstream linear actuator 52, in particular by its cylinder 521.
  • the cylindrical space E52 of said at least one downstream linear actuator 52 advantageously extends outside the lateral space E31 , E32 of the main 31 and terminal 32 arrows (and more particularly outside the lateral space E31 , E32 of the part of the main 31 and terminal 32 arrows facing said at least downstream linear actuator 52).
  • said at least one downstream linear actuator 52 is offset laterally with respect to the boom parts 31, 32, so as to extend facing the side faces 311, 321 of the latter.
  • Said at least one downstream linear actuator 52 is thus located outside the intermediate space delimited, on the one hand, between the vertical planes P311 of the main boom 31 and, on the other hand, between the vertical planes P321 of the boom terminal 32.
  • the maneuvering means 5 comprise two downstream linear actuators 52, identical and coplanar, located on either side of the main arrow 31 and the terminal arrow 32.
  • Each downstream linear actuator 52 is thus secured with a pair of side faces 311, 321 located on the same side of the articulated boom 3: a side face 311 of the main boom 31 and a side face 321 of the terminal boom 32, located on the same side of the articulated boom 3.
  • the upstream assembly means 10 are here secured with the cylinder 521 of the downstream linear actuator 52, at a distance from its upstream end 521 a , advantageously at its downstream end 521 b .
  • the upstream assembly means 10 are here secured to the closing ring 521b of the cylinder 521 of the downstream linear actuator 52.
  • Said downstream linear actuator 52 then extends on either side of the upstream assembly means 10.
  • the cylinder 521 of the downstream linear actuator 52 is thus intended to pivot around its downstream end 521 b , at the level of the upstream assembly means 10.
  • This cylinder 521 of the downstream linear actuator 52 extends, partially or entirely, projecting (or overhanging) with respect to the upstream assembly means 10 (upstream side).
  • the cylinder 521 then extends on the side of the support structure 2 and the rod 522 extends on the side of the terminal arrow 32.
  • the cylinder 521 extends opposite one of the side faces 311 of the main boom 31; and the rod 522 extends facing one of the side faces 321 of the terminal arrow 32 and one of the side faces 311 of the main arrow 31.
  • the spider 101 thus defines two degrees of freedom in rotation R1 , R2 , perpendicular to each other (advantageously a vertical axis of rotation R1 and a horizontal axis of rotation R2 ).
  • the spider 101 here consists of a ring within which is inserted the downstream end 521b of the cylinder 521 of the downstream linear actuator 52.
  • the ring 101 comprises two pairs of concentric orifices 1011, 1012 each defining one of the two degrees of freedom in rotation R1 , R2.
  • Two first concentric orifices 1011 receive journals 1013 cooperating with complementary blind orifices 1014, concentric, carried by the downstream end 521b of the cylinder 521 of the downstream linear actuator 52 (advantageously formed on the closing ring 521b on the rod side, designated by the same reference 521 b for the sake of simplicity), to define here the vertical axis of rotation R1 .
  • Two second concentric orifices 1012 receive trunnions 1015 carried by the fork 102 (one attached and the other fixed), to define here the horizontal axis of rotation R2 .
  • the downstream assembly means 11 are for their part secured to the free end 522b of the rod 522.
  • said at least downstream linear actuator 52 is advantageously secured to one of the side faces 321 of the terminal boom 32, at a distance from the downstream articulation means 36.
  • said at least upstream linear actuator 51 is for its part secured with, on the one hand, the support structure 2 and, on the other hand, the main boom 31.
  • the upstream linear actuator 51 is secured with, on the one hand, the upstream assembly means 15 at the level of the upstream end 511a of its cylinder 51 and, on the other hand, the means for downstream assembly 16 at the level of the free end 512b of its rod 512.
  • the upstream linear actuators 51 are also two in number, identical and coplanar, located on either side of the main boom 31.
  • said at least downstream linear actuator 52 confers an improved lever arm between the main boom 31 and the terminal boom 32.
  • the downstream linear actuator 52 When opening the terminal jib 32, the downstream linear actuator 52 is intended to oscillate around the first degree of freedom in rotation R1 (horizontal) defined by the upstream assembly means 10.
  • the mounting of the cylinder 521 of the downstream linear actuator 52 at its downstream end 521 b , by means of the upstream assembly means 10, further optimizes the buckling length which is limited solely to the length of rod 522 deployed (and no longer the total length of this downstream linear actuator 52).
  • the downstream linear actuator 52 also has a rotational clearance according to the first degree of freedom in rotation R1 (horizontal) and the second degree of freedom in rotation R2 (vertical), also defined by the means of upstream assembly 10.
  • the “ball joint” functions of the assembly means 10, 11 release the rotations and eliminate the parasitic moments, in particular the parasitic bending moments.
