Definitions

  • My present invention relates to improvements inaerial rope-ways comprising a stationary carrier rope and a travelling traction rope for the load carrying units.
  • the objects of the improvements disclosed herein are first to provide a simple construction for automatically disengaging the said units from the traction rope at the points provided therefore, second to readily reengage the said units to the traction rope, and third to erect curved sections by simply inclining the axes of the rope guiding rollers, without need of complicated intermediate stations and the like for the traction rope.
  • Fig. 1 is a side view or a section of the ropeway
  • Fig. 2 is a portion of Fig. l in a larger scale and, in dash-and-dot lines, another point of the ropeway,
  • Fig. 3 is an end-view of Fig. 2
  • Fig. 4 is a detail in top plan view.
  • the ropeway shown partly in Fig. 1, comprises a stationary carrier rope 10 which, as is conventional in aerial ropeways, is secured to supporting towers 12 through skids 11.
  • a traction rope 13 runs above the carrier rope 10 and is guided by means of rollers 14 which are mounted on the towers 12 and will be described subsequently.
  • the ropeway preferably is formed into an endless track so that the traction rope 13 has to be driven in one direction only, for which purpose means are provided which are known per se and not shown.
  • a plurality of load carrying units 15 are suspended from the rope 10.
  • Each unit 15 comprises a tub 17 for the material to be conveyed, which tub is pivoted to the legs of a strirrup 16.
  • the web of the stirrup is provided with a rigid hanger arm 18 of which the upper end is pivoted to a truck 19.
  • the latter comprises two rollers 20 which run on the rope 10 and each of which has a circumferential groove 21 for accommodating the rope.
  • a draw-bar 22 is pivoted to the top side of truck 19.
  • the upper free end of said draw-bar is pivoted to an element 23 which is engaged to the traction rope 13.
  • the shape of said element 23 may be clearly seen from Figs. 2 to 4.
  • the element 23 comprises a helical portion 24 which is engaged to the traction rope 13 and is connected to one end of a leg 26 through a horizontal portion 25 which is substantially at right angles to the traction rope.
  • the leg 26 extends in a vertical plane which is substantially parallel to the traction rope 13, and that end of leg 26 which is remote from the helically coiled portion 24 is bent oif at right angles.
  • Such bent-oft portion 27 is engaged in a suitably shaped recess at the upper end of the draw-bar 22 and serves as pivot for the element 23.
  • the pivot 26 stands substantially horizontal and transverse to the traction rope 13.
  • the leg 26 and the draw-bar 22 are situated laterally of the vertical plane passing through the traction rope 13.
  • the element 23 with its portions 24-27 is made of a single piece or round stock which is bent to the shape described.
  • the helical portion 24 comprises a turn of a little more than a single complete revolution and has a lead such that the traction rope 13 may be laterally introduced into the turn, when the latter is properly positioned with respect to the rope.
  • rollers 14 which guide the traction rope 13 comprise two guide flanges 28 and 29 of which the latter is toothed.
  • the portion 25 of element 23 projects into one of the gaps between the teeth or'liange 29 so as not to hinder the transport movement through the rollers 14.
  • the axes of the rollers 14 are horizontal on stright ropeway sections, as shown by solid llIlS in Fig. 3. In low-degree curves the roller axesare inclined, as shown at 14a in Fig. 3, whilst in high-degree curves the rolleraxes may be vertical, as shown at in Fig. 3.
  • the hanger 18 or the units 15 may be situated on the same side of the truck 19 as the draw-bar 22, as shown by solid lines at 18 in Fig. 3, but also on the opposite side as shown in Fig. 3 at 16a by dash-and-dot lines.
  • the traction rope 13 is run at such a spacing from the carrier rope 10 that the elements 23 or the units 15 are automatically locked to the traction rope, whereby the units 15 are taken along by the rope 13.
  • the draw-bar 22 then applies a turmng moment on the leg 25 of the element 23 m direction or the arrow P, whereby the axis of the turn 24 is set at an angle to the traction rope 13 so as to clamp the latter.
  • the units 15 are engaged thereto, whereby the traction force on the draw-bar 22 as required for overcoming the friction, accelerating the mass and for overcoming gradients, increases the clamping ettect by raising the turning moment in the sense of arrow P.
  • the spacing of the traction rope 13 from the carrier rope 10 is reduced, as shown in Fig. 2 at 13a by dash-and-dot lines.
  • the traction rope may be run underneath one or more of the rollers 14, as shown in Fig. 2.
  • the drawbar 22 and the element 23 assume the positions 220 and 23a shown by dash-and-dot lines in Fig. 2 with respect to the traction rope, in which the element 22a is disengaged from the traction rope.
  • the unit 15 thus is disengaged from the travelling rope 13 and may be loaded or unloaded after it has come to rest.
  • the appurtenant element 23 through coil 24 is engaged to the traction rope in the manner required, and the turning moment required for a clamping action is exerted by hand until the unit 15 thus engaged develops by itself the tuming moment according to arrow P.
  • An aerial ropeway for the transport of a load comprising a traction rope capable of movement in the direction of its axis, a stationary carrier rope substantially parallel to said traction rope, a traction rope-engaging member having a helical portion and an arm, said helical portion being provided with substantially one complete turn for engagement with said traction rope, a load carrying unit adapted to ride along said carrier rope, and a draw bar pivotally connected at one end to said load carrying unit, said arm of said member being pivotally connected to said draw bar at the other end of the latter for pivotal movement relative to said draw bar about an axis which is substantially horizontal and perpendicular to both said traction rope and said draw bar, the curvature of said helical portion being predetermined to effect auto matic locking of said member and thereby of said load carrying unit to said traction rope when the distance between said ropes exceeds a certain value, and to effect automatic disengagement of said member from said traction rope when the distance between said ropes is less than said certain value.
  • said arm of said member including a first leg portion disposed in a vertical plane parallel to said traction rope, one end of said first leg portion being connected to said helical portion, and a second leg portion connected to the other end of said first leg portion and extending at right angles to the latter, said draw bar being provided with a recess, said second leg portion being disposed within said recess and forming said axis of pivotal movement of said member relative to said draw bar.
  • said arm of said member including a portion which is disposed transversely to said traction rope in a substantially horizontal direction and interconnects said helical portion with said first leg portion, said draw bar being disposed in a vertical plane parallel to those passing through said traction rope and said first leg portion.
