Definitions

  • the present invention relates to the field of lifting objects to be moved horizontally during the movement of lifting and likely to initiate a swinging or swinging movement.
  • the dangling is due, on the one hand, to the movement of acceleration and braking of the lifting device in a horizontal plane and, on the other part, to the wind resistance offered by the object being lifted.
  • the invention is particularly applicable to the lifting of boxes or containers of parallelepiped shape, for example during their transfer from a storage area to the trailer of a heavy goods vehicle or to the platform of a railway wagon.
  • the boxes to be lifted do not have the same dimensions according to perpendicular axes, for example being cylindrical or rectangular, have a different wind resistance along the axis longitudinal X or transverse axis Y.
  • the anti-swaying effect can be unnecessarily high along the X axis while being too weak along the Y axis.
  • the object of the present invention is to remedy the drawbacks of the aforementioned devices and to propose an effect lifting device anti-swaying suitable for taking windbreaks from commonly used boxes, the wind resistance depending on the size of the surface of the walls of the box and their shape.
  • the device for lifting an object comprises at at least four cables supporting said object at least four points of attachment.
  • the four cables are arranged so as to reduce the slack of the object.
  • Each cable is arranged so as to constitute a means anti-sway along a first horizontal axis and anti-sway means along a second horizontal axis perpendicular to said first axis.
  • the anti-sway effect on each axis can be adapted to the wind resistance of a box.
  • the difference in anti-sway effect on the axes is obtained thanks to the difference in inclination of the plane of the cables between them. We can thus obtain the necessary anti-swaying effect depending on the depreciation requirements, without oversizing according to one axes.
  • the device comprises at least one lower pulley by cable secured to an attachment point of the object.
  • the device comprises an upper part provided with a cable winding means and at least one pulley cable guide, one end of each cable being fixed to said upper part.
  • each cable that is located between the lower pulley and the upper part can be placed in a plane inclined with respect to vertically and intersecting said first and second horizontal axes.
  • the means winding includes a winding drum of all cables and at least one cable return pulley, the so-called pulleys reference having their axis so as to facilitate the changes of planes, by vertical example. This guarantees good synchronization of cable movements.
  • the cable strands arranged on each side of a lower pulley form an acute angle between them.
  • the device comprises eight cables and eight coaxial lower pulleys two by two.
  • One end of a cable can be fixed near a pulley guide the same cable.
  • the angle formed by a cable with respect to a vertical plane including the first horizontal axis is between 4 ° and 16 °.
  • the angle formed by a cable with respect to a vertical plane including the second horizontal axis is between 8 ° and 30 °.
  • the lifting device comprises a transfer member 1 movable along the two axes of a horizontal plane forming part of a gantry or transporter bridge, not shown.
  • the transfer member 1 comprises a drum winding 2 driven in rotation by a reduction gear and a motor not represented.
  • the transfer member 1 also includes pulleys main guide 3 and secondary idler pulleys 4 of axis vertical.
  • the transfer member supports a spreader 5 by the cables 6.
  • the spreader 5 is equipped with points attachment provided with lower pulleys 7 through which the cables 6.
  • a box 8 which can be of parallelepiped shape is supported by lifting beam 5 by means of arms 9, or by latches turning points not shown.
  • Each cable 6 has one end wound on the drum 2 and the other end fixed to an attachment point 10 of the transfer member 1, arranged near the main return pulley of the same cable 6.
  • the drum 2, the main guide pulleys 3a at 3 o'clock, the secondary return pulleys 4a at 4 o'clock and the attachment points 10a to 10h have been shown without the transfer device for clarity drawing.
  • the cable 6a is fixed at one end to the attachment point 10a of the transfer member, descends into the pulley 7a, rises in parallel, pass through the main guide pulley 3a and then into the secondary return pulley 4a before winding on the drum 2.
  • the attachment point 10a is arranged near the main pulley guide 3a so that the two strands of the same cable 6a are parallel and thus avoid untimely cable crossings.
  • the secondary return pulley 4a is used to align the cable 6a which must be substantially parallel to the longitudinal axis X to wrap around the drum 2. The same applies to the other cables 6b to 6h.
  • the pulleys 7a to 7g are mounted in counter-rotating coaxial pairs. This arrangement simplifies the construction of the spreader bar 5.
  • Each pair of cables 6a and 6b, 6c and 6d, 6e and 6f, 6g and 6h passing through a pair of coaxial pulleys 7a and 7b, 7c and 7d, 7th and 7f, 7g and 7h respectively, is arranged substantially in the same plane inclined to the vertical and intersecting the longitudinal axes X and transverse Y.
  • the simultaneous anti-sway effect along the two axes X and Y and its differentiation along these same two axes depends in particular on the inclination of the planes of the pairs of cables with respect to the vertical, this within the maximum limits of the dimensions desired for the transfer organ.
  • These planes are symmetrical about the axis longitudinal X and transverse axis Y with a slight offset ( Figures 3 to 5) to prevent crossing of cables.
  • a cable 6 takes a maximum inclination from vertical when the lifter 5 is in the high position, for example a maximum inclination of 16 ° from a vertical plane passing through the X axis and 30 ° from relative to a vertical plane passing through the Y axis.
  • the inclination cable 6 when the lifter 5 is in the low position is respectively of the order of 4 ° and 8 °. So the sizing of cables 6 must be carried out from the forces verticals which are exerted in this position.
  • the cable sizing is optimized, which reduces their diameter. This reduction in their diameter allows a reduction in the cost of the entire chain kinematics by reducing the diameter of the different pulleys and the drum and by reducing the torque and therefore the cost of the reduction gear associated with the drum 2.
