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.
  • the object of the present invention is to remedy this drawback.
  • each harness is pivotally mounted on the carriage to allow a movement in the vertical plane containing the cable during a lifting of the harness of said cable and that each harness has a fork guide remaining engaged on the cable in the pivoted position of the harness during an untimely lifting of the latter to prevent any stalling of the harness.
  • the fork In normal operation, the fork is inactive, its teeth extending parallel to the direction of the cable in the extension of the harnessing 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 comes to rest automatically 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 latch downward movement is caused by the imbalance between the weight portion ar- "Rière and the front part of the fifth wheel with respect to its pivot axis. This action is accentuated by that of a hairpin spring to increase the speed of movement
  • the uncoupling of the load naturally requires a corresponding lifting.
  • the fork extends at the rear of the harness to avoid any bending during engagement on the cable, in particular when the load is coupled.
  • the assembly is particularly simple and robust and does not require any special locking or control mechanism.
  • the harness comprises a movable lug capable of cooperating with the cable to prevent any sliding of the harness on the cable.
  • the adhesion of the harness by jamming on the cable may be insufficient on the steep sections and it has already been proposed to increase this adhesion by the use of wedging surfaces at a small angle at the top of the V and / or by striations or pins provided on the surfaces in contact with the cable.
  • the reduction of the angle is limited by the obligation to wedge a thinned cable without excessive interlocking, risking obstructing the passage on the pulleys.
  • Fixed lugs lose their effectiveness totally or partially on worn cables or due to their own wear, or even when the harness is lifted.
  • the movable locking lug By mounting the movable locking lug on the harness, it is ensured that it remains 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 is arranged at the front of the harness so as to be raised in the pivoted position of the harness.
  • 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 supporting the cable have laterally grooves in the cable guide groove allowing increased lateral pivoting of the harnesses without risk of contacting the edges of the wedging surfaces with the bottom of the pebble groove.
  • This arrangement is particularly advantageous for harnesses with a small angle of wedging surfaces whose penetration depth on the cable varies greatly with the thinning of the cable. This possibility of having smaller angles increases the adhesion of the two surfaces in contact with the cable.
  • a tractor-carrier cable 10 of an overhead cable conveyor runs continuously for transporting 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 by means of a hinge pin 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 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 allows compensation for wear or thinning of the cable 10 and is determined to obtain a maximum wedging force for a given load.
  • the wedging surfaces 26, 28 extend behind the harness 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 extend in the longitudinal direction of the cable 10, without increasing the clearance gauge on the support rollers.
  • the device works as follows:
  • the carriage 14 is brought into line with the cable 10 and by rolling on an inclined rail is placed on the cable 10.
  • the harnesses 18, 20 tightened on the cable 10 provide support and training for the load and from the carriage 14 towards the arrival station where the uncoupling takes place automatically by a ramp which lifts the carriage 14.
  • the carriage 14 inadvertently lifts during the journey, in particular during an oscillation of the cable 10 towards the position 10 ', the wedging surfaces 26, 28 are released from the cable.
  • the harnesses 18, 20 pivot in a counterclockwise direction (FIG. 1) downwards, the cable 10 'remaining trapped in the forks 30, 32.
  • the lift of the carriage 14 must be sufficient to release the cable from the forks 30, 32.
  • the length of the forks 30, 32 is chosen according to the maximum lift heights of the carriage 14 to avoid any risk of derailment .
  • the forks 30, 32 can contribute to guiding the carriage 14 during coupling or uncoupling.
  • a pin 34 On the anterior portion 36 of the wheel 18, 20 is slidably mounted a pin 34, within a housing sen - siblement vertical in the fifth wheel coupling position (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 to match the circumference 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 a steep 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.
  • 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 the locking function even on a thinned cable.
  • FIG. 5 there is seen a groove profile of a roller 46 for supporting the cable 10, designed to facilitate the passage of the coupling harnesses 18, 20.
  • the cable 10, shown in FIG. 5, is thinned and at the wear limit and the fifth wheel 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 other 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 in the usual manner.
  • the assembly is arranged so that only the central position of the cable 10, shown in FIG.
