[Operation] In the bending equipment having such a configuration, when the gripping machine passes through the inner bending portion of the cableway, the height position for gripping the cord is fixed to the guide roller while the height position for gripping the cord is fixed. Is guided by the guide rails to be tilted and displaced, and passes through the bent portion while avoiding interference with the receiving wheel.

[Embodiment] Hereinafter, details of the present invention will be described with reference to the drawings showing one embodiment.

As shown in the plan view of the cableway line in FIG. 1, a rope 3 is stretched and circulated between the driving pulley 1 and the tensioning pulley 2 at both ends, and between the driving pulley 1 and the tensioning pulley 2. , The line 3
, 4 are arranged in the inner bending section 20 and the outer bending section 21 at substantially equal intervals. Further, an inner lift-up rail 6 and an outer guide rail 7 are attached to the inner bent section 20 and the outer bent section 21 along the outer side of the rope 3 in a plan view substantially in parallel.

The inner lift-up rail 6 is formed by the bent inner cord 3 and a bent section 6b on a concentric circle and two straight sections 6a, 6c in a plan view, and the cross section of the bent section 6b is substantially concave. In the shape of a gutter, the straight section 6a has a groove width of the tip portion 6d slightly widened in a plan view, and the tip portion 6d is located below the bent section 6b. 6a has a structure inclined downward with respect to the bent section 6b. Similarly, the straight line section 6c has a symmetrical structure with respect to the straight line section 6a. On the other hand, the outer guide rail 7 is concentrically provided along the outer bent section 21 in a plan view, but in the outer bent section 21, the gripping machine is provided.
The straight line section 7a and the straight line section 7c are shorter than the inner lift-up rail 6 because 11 does not need to incline the gripping machine 11 since it passes outside the horizontal receiving wheels 4, 4 ,. It has a shape.

On the other hand, as shown in FIG. 2, the gripping machine 11 has pins 13 and 13 which are inserted and projected in parallel with the cord 3. Similarly, in the suspension device 16, pins 14 and 14 are inserted and protruded in parallel with the rope 3. Further, the pins 13, 13 of the gripping machine 11 and the pins 14, 14 of the suspension machine 16 are connected by link plates 12, 12, and the gripping machine 11 swings with respect to the suspension machine 16. It is structured so that it can move freely. Further, as shown in FIG. 9, the suspension machine 16 has two guide rollers 15, 15 pivotally mounted on a bracket 17 fixed to the suspension machine 16.

As mentioned above, the gripper 11 that grips the cord 3 has a pin.
The suspension device 16 and a seat (not shown) are oscillated so as to be swingable via link plates 12 and 12 between the pins 13 and 13 and pins 14 and 14, and the carrier 10 is operated in the straight section of the track. Two
As shown in the figure, the pins 13,1 inserted into the gripping machine 11
The link plates 12, 12 pivotally mounted between the pins 3 and 3 and the pins 14, 14 inserted in the suspension unit 16 are positioned substantially vertically, so that the suspension unit 16 is suspended. FIG. 3 shows the guide rollers 15 and 15 pivotally mounted on the bracket 17 of the suspension machine 16 at the carrier position a in the straight section 6a of the inner lift-up rail 6 in which the carrier 10 is just before the inward bending section 20. Is a state in which rolling has started on the inner lift-up rail 6. FIG. 4 shows that the carrier 10 further approaches the inner bent section 6b, the guide rollers 15 and 15 roll on the straight section 6a of the inner lift-up rail 6, and the suspension machine 16 moves upward. , The gripping machine 11 is tilted by about 90 °, and the horizontal catching wheels 4, 4 for bending the rope 3 are provided.
…, A position where you can pass 4. The positional relationship between the rope 3 and the inner lift-up rail 6 is constant while the carrier 10 is operating in the inner bending section 20, and the gripping machine 11 is almost 90 degrees as shown in FIG. Maintained by inclining nearly.
When the carrier 10 further advances and the inner lift-up rail 6 straight section 6c is again moved in the direction of the arrow 18 in FIG. 7 in the order of the position e, f, g shown in FIG. The gripping machine 11 is gradually tilted in the direction opposite to the tilting direction, that is, the position of the gripping machine 11 of FIG. 3 is changed from the position of the gripping machine 11 of FIG. When the carrier 10 further advances and passes through the inner lift-up rail 6, as shown in FIG. 2, the gripping machine 11 and the suspension machine 16 are swung via the pins 13 and 13 and the pins 14 and 14. The link plate 12, 12 which is freely pivoted is substantially vertical, and the carrier 10 is operated.

Further, since the guide roller 15, 15 pivotally attached to the bracket 17 of the suspender 16 rolls on the inner lift-up rail 6, the carrier 10 is laterally moved by centrifugal force when passing through the inner bent section 20. Shaking is prevented, and stable operation of the carrier 10 is always maintained even in the inner bent section 20.

On the other hand, when the carrier 10 passes through the outer bending section 21 shown in FIG. 1, since the gripping machine 11 is located outside the cord 3, the horizontal ropes 4, 4 ,. It is not necessary to tilt the gripping machine 11 when passing through 4, and the guide rollers 15, 15 pivotally attached to the bracket 17 of the suspension machine 16 as shown in FIG.
Rolling on the outer guide rail 7 prevents lateral roll of the carrier 10 due to centrifugal force when passing the outer bent section 21, as in the case where the carrier 10 passes through the inner bent section 20. It is designed to always maintain a stable bending operation.

EFFECTS OF THE INVENTION The cableway bending equipment of the present invention has the following advantages over the conventional equipment.

Since a plurality of relatively small-diameter horizontal receiving wheels are used for bending, inward bending is required in a bent line that requires a large bending radius, as compared with the case where one large-diameter pulley is used for bending. The space required outside the line of the section can be reduced.

Since the bending is gentler than that of one large-diameter pulley, the centrifugal force is reduced, and the lateral vibration is reduced and the riding comfort is improved.

A suspension structure in which a suspension machine is swingably connected to a gripping machine by a link plate via a pin, and two guide rollers are pivotally attached to a bracket fixed near the link plate of the suspension machine, and an inward bending section is provided. By attaching an inner lift-up rail along which the guide roller rolls along the bending section of the rope, the gripping machine can be tilted more smoothly and reliably in the inner bending section so that the horizontal support is received. It is possible to pass the rope and prevent rolling of the carrier due to centrifugal force, and also to prevent lateral roll of the carrier by attaching an outer guide rail even in the outer bending section. is there.
