Definitions

  • the present invention relates to the technical field of cranes with tower, with distributing jib, i.e. a crane jib with a raceway along which a carriage is mounted rolling, under which is located the lifting hook, moved with this carriage.
  • the invention is concerned more particularly to a distribution cable circuit, with a device for tension of this cable, for a crane of the kind concerned, the "cable of distribution ”being a motorized cable which, in this kind of crane, ensures the movement of the carriage along the arrow.
  • the distribution cables of tower cranes must be tensioned, with a properly controlled tension.
  • the distribution cable circuits must be compatible with the boom folding positions.
  • the distribution cable can be a single cable, describing a loop path.
  • This cable can also be made in two parts, i.e. composed of a rear distribution cable and a front distribution cable.
  • the tensioning device with articulated arm and spring gas heater is mounted in the rear part of the boom foot element.
  • the second end of the distribution cable rear, or front distribution cable is attached to a tension drum located on the boom carriage, this drum being provided with means drive and rotation lock, for the tensioning of this cable.
  • the gas spring of the tensioning device develops a stroke significant, with constant pushing effort, and it requires no intervention to compensate for the lengthening of the distribution cable, during the whole life of the cable.
  • the large stroke of the gas spring allows a “lifetime” adjustment of the tension of the rear distribution cables and before.
  • the tensioning device which does not require hauling and is located on the boom foot, preferably in the rear part of this foot arrow, only induces a weak moment due to its dead weight
  • the tension drum located on the carriage, at one end of one rear or front distribution cables, allows pre-tensioning distribution cables from ground level, without being imposed, to this operation, a defined position of the boom carriage on the free part of the arrow.
  • the tension keeps this checkerboard permanently under tension, avoiding relaxation of the cable under the effect of the lifted load, when the crane works with its boom identified.
  • the technical solution according to the invention ensures the exact compensation of the length of the distribution cable, at the articulation between two consecutive boom elements, by adapting in particular to an articulation device with two connecting rods, 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 route of the front distribution bypasses the connecting axis of the members of the rear boom element and the front boom element.
  • FIG. 1 schematically shows a collapsible tower crane which comprises a fixed base chassis 1 on which a chassis is mounted turning 2, orientable around a vertical axis 3.
  • the crane comprises a mast 4, made of two elements 5 and 6 hinged together around a horizontal axis 7.
  • the lower mast element 5 is articulated by its base, around an axis horizontal 8, in front of the rotating frame 2.
  • At the top of the mast element upper 6 is articulated, around a horizontal axis 9, an arrow distributor10 along which a carriage 11 can be moved, the arrow 10 being composed here of two elements, which are a rear element called foot of arrow 12 and a front element called arrowhead 13.
  • this crane also includes guy lines 14 for dressing the mast 4, a retainer 15 of the boom 10, and a ballast 16 carried by the part rear of rotating frame 2.
  • the arrowhead 12 has a triangular section, and the tip of arrow 13 has a U-shaped section.
  • This arrowhead 13 is articulated, by its rear part, to the front part of the jib foot 12, around a horizontal axis 17 located substantially halfway up the arrow 10.
  • the two arrow elements 12 and 13 are fitted one in the other, the triangular section of the jib foot 12 nesting in the section in “U” shape of the arrowhead 13 turned over.
  • the articulation device 18, previously described, is motorized by a double-acting cylinder 28, the body 29 of which is articulated, by its end rear, on the jib foot 12 at the level of the upper chord 30, at one certain distance from 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 allows free passage to the axis 22; the double rod configuration of this bent rod 23, as well as of the second connecting rod 25, gives free passage to the rod 31 of the jack 28.
  • the upper chord 30 of the jib foot 12 is connected, by truss structures 32, at the two lower members 33 of this foot of arrow 12 which constitute a section of the rolling path of the carriage 11.
  • the arrowhead 13 has two upper members 34 connected by truss structures 35, with two lower members 36 which constitute a another section of the carriage track 11.
  • the translational movement of the carriage 11, along its path bearing 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 38 (see Figure 1, below).
  • the command movement of the carriage 11 is effected by means of a cable rear distribution 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 Figure 3) with a horizontal axis, carried by the head of mast 42, then on a pulley 43 with a horizontal axis, carried by the rear part of the boom foot 12.
  • the rear distribution cable 39 passes over a pulley 44 of horizontal axis, mounted on an arm 45 articulated around an axis horizontal 46 on the jib foot 12, then this cable 39 returns to a pulley 47 with a horizontal axis carried by the rear end of the jib foot 12, this last pulley 47 located behind the previous pulley 44.
  • the cable rear distribution 39 extends forwards over 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 the reference 48, is located on the circuit of the cable rear distribution 39, at the rear part of the jib foot 12.
  • This tensioning device 48 comprises the aforementioned pulley 44, mounted at the end of the arm 45 articulated on the jib foot 12.
  • the tensioning device comprises also a gas spring 49, articulated between an attachment point 50 on the foot of arrow 12, on the one hand, and the end of the arm 45 articulated on the foot of arrow 12, on the other hand.
  • the gas spring 49 thus mounted, acts on the arm 45, therefore 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 to a tension drum 51 located on the carriage 11, the circuit of this cable 40 being as follows (see FIGS. 1, 2, 3 and 4):
  • the front distribution cable 40 rises along the mast 4, and it goes on a pulley 52 with a horizontal axis, carried by the mast head 42, then on a pulley 53 with a horizontal axis, carried by the rear part of the jib foot 12.
  • the two pulleys 52 and 53 can be coaxial respectively to the two corresponding pulleys 41 and 43 over which the distribution cable passes rear 39.
  • the front distribution cable 40 extends forward, along and along the entire length of the boom 12, up to a pulley 54 with a horizontal axis, mounted on the angled connecting rod 23 belonging to the articulation device 18 between the jib foot 12 and the point arrow 13.
  • the cable 40 then passes over a pulley 55 with a horizontal axis, mounted at the upper front end of the jib foot 12, then on another pulley 56 with a horizontal axis, mounted in front of and close to the previous one, always at the upper front end of the jib foot 12.
  • the front distribution cable 40 passes over a pulley 57 with a horizontal axis, mounted on the other connecting rod 25 of the articulation device 18, at know the connecting rod 25 articulated on the rear end of the arrowhead 13. Then the cable 40 extends forward, along the arrowhead 13 and over the entire length thereof, up to a pulley 58 with a horizontal axis, carried by the front end of the arrowhead 13 (see detail in FIG. 2).
  • the front distribution cable 40 extends then backwards, along the arrowhead 13 and over the entire length from this, to a pulley 59 with a horizontal axis, located at the rear end lower of the arrowhead 13 (this when the carriage 11 is located on the boom foot 12, as shown in Figures 4 and 5).
  • the front distribution cable circuit 40 includes a final horizontal axis pulley 60, carried by the lower front end of the foot arrow 12.
  • the two pulleys 54 and 57 mounted respectively on the two connecting rods 23 and 25 form, with the other two pulleys 55 and 56 mounted at the level of the upper chord 30 of the jib foot 12, a cable length compensation system.
  • the front distribution cable 40 bypasses the connecting axis 22 respective upper members 30 and 34 of the jib foot 12 and the arrowhead 13, this also in the aligned position of arrow 10 ( Figure 4) than in its folded position ( Figure 5).
  • the second end of the front distribution 40 is fixed on a drum 51, carried by the carriage 11.
  • the drum 51 is provided with a square for driving its axis of rotation, capable of be moved using a key, means for blocking the rotation of this drum 51 being also provided. These means allow the pre-tensioning of the cables 39 and 40 (as detailed below), as well as the possible storage of a excess cable length, if the length of the cable is reduced arrow 10.
