Definitions

  • the present invention relates to the technical field of tower cranes, with distributing boom, that is to say a crane boom provided with a raceway along which is mounted rolling a carriage, under which is located the hook of lifting, moved with this cart.
  • the invention is more particularly concerned with a distribution cable circuit, with a device for tensioning this cable, for a crane of the type in question, the "distribution cable” being a motorized cable which, in this type of crane, ensures moving the carriage along the arrow.
  • distribution cables for tower cranes must be tensioned with a properly controlled tension.
  • circuits of the distribution cables must be compatible with the folding positions of the boom.
  • the distribution cable may be a single cable, describing a loop path.
  • This cable can also be made in two parts, that is to say composed of a rear distribution cable and a front distribution cable.
  • the tensioning device with articulated arm and gas spring is mounted in the rear part of the boom foot element.
  • the second end of the rear distribution cable, or the front distribution cable is fixed on a tension drum located on the trolley arrow, this drum being provided with means for driving and locking in rotation, for the tensioning of this cable.
  • the gas spring of the tension device develops a large stroke, with a constant thrust force, and it does not require any intervention to make up the elongations of the distribution cable throughout the life of the cable.
  • the large stroke of the gas spring allows a "lifetime" adjustment of the tension of the rear and front distribution cables.
  • the tension device which does not require hauling and is located on the foot of the boom, preferably in the rear part of the boom foot, induces only a weak moment due to its dead weight.
  • the tensioning drum located on the carriage, at one end of one of the rear or front distribution cables, makes it possible to pre-tension the distribution cables from the ground level without being imposed for this operation. , a defined position of the arrow carriage on the free part of the arrow.
  • the tensioning device Being mounted on the rear distribution cable, the tensioning device keeps it permanently energized, avoiding the relaxation of the cable under the effect of the raised load, when the crane works with his arrow up.
  • the technical solution according to the invention ensures the exact compensation of the length of the distribution cable, at the joint between two consecutive deflection elements, by adapting in particular to a two-link articulation device, such as described in the previous French patent application FR 2796632 A (or its equivalent EP 1072553 A1) in the name of the Applicant, in which case the path of the front distribution cable makes it possible to bypass the connecting axis of the upper chords of the boom element rear and the front boom element.
  • FIG. 1 schematically represents a crane with foldable tower which comprises a fixed base frame 1 on which is mounted a rotating frame 2, orientable about a vertical axis 3.
  • the crane comprises a mast 4, made in two elements 5 and 6 articulated together about a horizontal axis 7.
  • the lower mast element 5 is articulated by its base, about a horizontal axis 8, to the front of the rotating frame 2.
  • At the top of the upper mast element 6 is articulated around a horizontal axis 9, a distributing arrow 10 along which is movable a carriage 11, the arrow 10 being composed here of two elements, which are a rear element said foot of arrow 12 and a front element said Arrowhead 13.
  • this crane further comprises struts 14 for training the mast 4, a device 15 for retaining the boom 10, and a ballast 16 carried by the rear portion of the rotating frame 2.
  • the boom foot 12 has a triangular section
  • the boom tip 13 has a U-shaped section.
  • This arrowhead 13 is articulated, by its rear part, to the front part of the jib 12, around a horizontal axis 17 located substantially halfway up the arrow 10.
  • the two boom elements 12 and 13 are nested one inside the other, the triangular section of the boom foot 12 nesting in the section in " U "of the arrowhead 13 returned.
  • the hinge device 18, previously described, is powered by a double-acting cylinder 28, whose body 29 is hinged, at its rear end, on the jib foot 12 at the upper chord 30, at a certain distance of the front end of this jib foot 12.
  • the rod 31 of the cylinder 28 is articulated, by its front end, to the connecting axis 27 of the two connecting rods 23 and 25.
  • the elbow of the first connecting rod 23 leaves a free passage to the axis 22; the double rod configuration of this crank rod 23, as well as the second rod 25, leaves a free passage to the rod 31 of the cylinder 28.
  • the upper chord 30 of the jib foot 12 is connected, by trellis structures 32, to the two lower chords 33 of this jib 12 which constitute a section of the tread of the trolley 11.
  • the jib tip 13 comprises two chords 34 connected, by lattice structures 35, two lower ribs 36 which constitute another section of the tread of the carriage 11.
  • the translational movement of the carriage 11, along its raceway on the boom 10, is controlled from a motorized winch of distribution, provided with a winding drum 37 and located, in the example illustrated, in the region of the mast foot 38 (see Figure 1, bottom).
  • the movement control of the carriage 11 is effected by means of a rear distribution cable 39 and a front distribution cable 40.
  • the rear distribution cable 39 rises along the mast 4, and it passes over a pulley 41 (see FIG. 3) of horizontal axis, carried by the mast head 42, then on a pulley 43 of horizontal axis, carried by the rear part of the boom foot 12. Then, the rear distribution cable 39 passes over a pulley 44 of horizontal axis, mounted on an arm 45 hinged about a horizontal axis 46 on the foot of boom 12, then this cable 39 returns to a pulley 47 of horizontal axis carried by the rear end of the jib foot 12, the latter pulley 47 being located behind the previous pulley 44. Finally, the rear distribution cable 39 extends towards the before on a variable length, along the arrow 10 to the carriage 11 on which is fixed its second end.
  • the tensioning device designated as a whole by reference numeral 48, is located on the circuit of the rear distribution cable 39, at the rear part of the boom foot 12.
  • This device tension 48 includes the aforementioned pulley 44, mounted at the end of the articulated arm 45 on the boom foot 12.
  • the tensioning device also comprises a gas spring 49, articulated between a point of attachment 50 on the boom foot 12 on the one hand, and the end of the articulated arm 45 on the boom foot 12, on the other hand.
  • the gas spring 49 thus mounted, acts on the arm 45, and thus on the pulley 44, in the direction indicated by an arrow F, in other words, towards the front.
  • the front distribution cable 40 has a first end, fixed on the other side of the winding drum 37 of the distribution winch, while its other end is fixed on a tension drum 51 located on the carriage 11, the this cable 40 being the following (see FIGS. 1, 2, 3 and 4):
  • the front distribution cable 40 rises along the mast 4, and it passes over a pulley 52 of horizontal axis, carried by the masthead 42, then on a pulley 53 of horizontal axis, carried by the rear part
  • the two pulleys 52 and 53 may be coaxial respectively with the two corresponding pulleys 41 and 43 on which the rear distribution cable 39 passes.
  • the front distribution cable 40 extends forward, along the boom foot 12 and over the entire length thereof, to a pulley 54 of horizontal axis, mounted on the bent rod 23 belonging to the articulation device 18 between the jib foot 12 and the tip arrow 13.
  • the cable 40 then passes on a pulley 55 of horizontal axis, mounted at the upper front end of the jib 12, then on another pulley 56 of horizontal axis, mounted in front of the previous one and close to this one, always at the upper front end of the foot of arrow 12.
  • the front distribution cable 40 passes on a pulley 57 of horizontal axis, mounted on the other connecting rod 25 of the articulation device 18, namely the connecting rod 25 articulated on the rear end of the tip of arrow 13. Then the cable 40 extends forward, along the arrowhead 13 and over the entire length thereof, to a pulley 58 of horizontal axis, carried by the front end of the arrowhead 13 (see detail in Figure 2).
  • the front distribution cable 40 then extends rearward, along the arrowhead 13 and over the entire length thereof, to a pulley 59 of horizontal axis, located at the lower rear end of the boom tip 13 (this when the carriage 11 is on the boom foot 12, as shown in Figures 4 and 5).
  • the circuit of the front distribution cable 40 comprises a last pulley 60 of horizontal axis, carried by the lower front end of the jib 12.
  • the two pulleys 54 and 57 respectively mounted on the two connecting rods 23 and 25 form, with the two other pulleys 55 and 56 mounted at the level of the upper chord 30 of the jib 12, a system for compensating the length of the cable. Passing on these two pulleys 55 and 56, the front distribution cable 40 bypasses the connecting pin 22 of the respective upper ribs 30 and 34 of the jib 12 and of the jib 13, this also in the aligned position arrow 10 (FIG. 4) only in its folded position (FIG. 5).
  • the second end of the front distribution cable 40 is fixed on a drum 51 carried by the carriage 11.
  • the drum 51 is provided with a drive square of its axis of rotation, which can be moved to the using a key, locking means in rotation of the drum 51 are also provided. These means allow pre-tensioning of the cables 39 and 40 (as detailed below), as well as the possible storage of excess cable length, in the event of a decrease in the length of the arrow 10.
