Definitions

  • the invention relates to a continuous cable overhead cable transport installation comprising load support carriages, capable of being coupled to the tractor-carrier cable by harnesses placed on the cable and having reverse V wedging surfaces. which overlap and grip the cable under the effect of the weight of the load transported, each harness being pivotally mounted on the carriage to allow movement in the vertical plane containing the cable.
  • the object of the present invention is to remedy this drawback.
  • the installation according to the present invention is characterized in that the wedging surfaces of each harness extend by two teeth forming a guide fork, means being provided for urging the harness in pivoting towards a position in which the teeth frame the cable when, during an untimely lifting of the harness, the wedging surfaces are released from the cable.
  • the fork In normal operation, the fork is inactive, its teeth extending parallel to the direction of the cable in line with the wedging surfaces of the harness on the cable.
  • the cable emerges from the wedging surfaces in an inverted V and allows the pivoting of the harness bringing the fork into the active, lowered position, straddled on the cable.
  • This fork guides the harness which automatically rests on the cable in the coupling position at the end of the oscillation.
  • the length of the fork tines must be sufficient to guide the harness during the maximum lifting amplitudes likely to occur during operation.
  • the fork extends at the rear of the harness to avoid any bending when unloading on the cable, in particular when coupling the load.
  • the assembly is particularly simple and robust and does not require any special locking or control mechanism.
  • the grip of the harness by jamming on the cable may be insufficient, knowing the long slope sections and it has already been proposed to increase this grip by the use of jamming surfaces carrying a protruding lug which is embedded in the circumference of the cable (DE-C-78.956).
  • Fixed lugs lose their effectiveness in whole or in part on worn cables or due to their own wear, or even when the harness is lifted.
  • the locking lug is mounted mobile on the harness and urged in contact with the cable.
  • the edge of the lug in contact with the cable advantageously follows the periphery of the cable and is shaped to be inserted between two strands to increase the locking effect.
  • the lug When the harness has a guide fork, the lug is disposed at the front of the harness on the opposite side of the fork with respect to the articulation axis, so as to be raised in the pivoted position of the harness.
  • the lug is advantageously secured to a vertical slide urged by gravity or by a spring in the projecting position in contact with the cable.
  • the harness can include several movable pins, integral or independent, these pins can be used in combination or not with the guide fork.
  • the load support trolley generally has two coupling harnesses and it is advantageous to determine the spacing between the two harnesses, so that when the lug of one of the harnesses is inserted between two strands of the cable, the lug of the other harness is in abutment on a strand, so as to be assured of the engagement of at least one lug between strands for any relative position of the carriage.
  • the rollers or pulleys for supporting the cable have laterally guide grooves of the groove cable allowing increased lateral pivoting of the harnesses without risk of contact of the edges of the wedging surfaces with the bottom of the roller groove.
  • This arrangement is particularly advantageous for harnesses with a small angle of the wedging surfaces whose penetration depth on the cable varies greatly with the thinning of the cable. This possibility of having smaller angles makes it possible to increase the adhesion of the two surfaces in contact with the cable.
  • a tractor-carrying cable 10 of an overhead cable conveyor runs continuously for the transport of loads along the line.
  • the loads or skips are coupled to the departure station with cable 10 and automatically uncoupled from the arrival station.
  • Each bucket is fixed by a hanger of which only the axis 12 is shown, to a carriage 14 via 'an axis of articulation 16.
  • the carriage 14 comprises two harnesses 18, 20 for coupling to the cable 10, which are pivotally mounted on axes 22, 24 symmetrically of the axis 16 and will be described in detail below.
  • the carriage 14 further comprises rollers (not shown) capable of rolling on transfer rails in the stations.
  • the harnesses 18, 20 are identical and only one 18 is described in detail below, more particularly with reference to FIGS. 3 to 5.
  • the body of the harness 18, articulated on the axis 22, has at its base two surfaces wedging 26, 28, or fixed jaws arranged in inverted V to come cover the cable 10 in the coupled position of the harness 18 and tighten the cable 10 under the effect of the weight of the load transported.
  • the inclination of the wedging surfaces 26, 28 makes it possible to compensate for the wear or the thinning of the cable 10 and it is determined to obtain a maximum wedging force for a given load.
  • the wedging surfaces 26, 28 extend behind the fifth wheel 18 by two teeth 30, 32 forming a fork capable of framing the cable 10. In the coupling position shown in the figures, the teeth 30, 32 s 'extend in the longitudinal direction of the cable 10, without increasing the clearance gauge on the support rollers.
  • a lug 34 On the front part 36 of the harness 18, 20 is slidably mounted a lug 34, inside a substantially vertical housing in the coupling position of the harness (fig. 2).
  • the upper part of the lug 34 carries a head 38 limiting the sinking of the lug 34 and subjected to the action of a leaf spring 40, which pushes the lug 34 to the bottom of its housing.
  • the lower part of the lug 34 is shaped as an edge 42 which opens into the bottom of the groove confined by the wedging surfaces 26, 28.
  • the edge 42 cooperates with the upper face of the cable 10 engaged between the surfaces 26, 28 and the edge 42 is inclined relative to the axis of the cable 10 by an angle corresponding to the slope of the strands of the cable 10 to allow its insertion between two successive strands.
  • the edge 44 of the edge 42 is concave for follow the edge of the cable.
  • the stroke of the lug 34 is sufficient to maintain in any case the contact with the cable clamped between the surfaces 26, 28.
  • the presence of the lug 38 increases the grip of the harness and allows the crossing of sections with strong slope.
  • the articulation of the harnesses 18, 20 on the carriage 14 avoids any engagement of the lug 34 prior to coupling by wedging between the surfaces 26, 28 and therefore any wear by friction on the cable. 10.
  • the spacing of the axes 22, 24 of articulation of the harnesses 18, 20 is determined as a function of the pitch of the helix of the strands of the cable 10, so as to always have at least one of the lugs 34 engaged between strands.
  • the lug 34 can easily be replaced in the event of wear and thanks to its mobility it ensures locking function even on a thinned cable.
  • the cable 10, shown in FIG. 5, is thinned and at the wear limit and the settette 18 rests practically by its bottom on the cable 10.
  • the roller 46 has a central groove 48 for guiding the cable 10 framed on the side and another of grooves 50, 52, the spacing of which corresponds to the spacing of the lower edges 54, 56 of the fixed clamping jaws with wedging surface 26, 28.
  • the grooves 50 52 are delimited laterally by the flanges 58, 60 of the usual way.
  • the assembly is arranged so that only the central position of the cable 10, shown in FIG.
