Abstract

PROBLEM TO BE SOLVED: To provide an inflected cableway permitting a narrower width of the passing region of objects to be carried in the halfway portion thereof. SOLUTION: Inflection sheaves 11A and 11B disposed at an inflection point 17 and inflection sheaves 21A and 21B disposed at an inflection point 18 are arranged to have predetermined different vertical levels respectively. The difference in vertical level between the upper and lower cables only at an extent not to cause the mutual interference of objects 1 to be carried narrows the horizontal interval between the upper and lower cables to remarkably narrow the width of the passing region of the carried objects between the inflection points 17 and 18 as compared with existent devices.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a bending cableway,
It is useful when applied to transport equipment at ski resorts.

[0002]

2. Description of the Related Art FIG. 5 is a plan view showing a conventional bendable cableway, and FIG. 5A shows a one-loop bendable cableway.
(B) shows a two-loop bending cableway.

In a one-loop bendable cableway shown in FIG. 5 (a), a rope 64 has a starting point and an end point 6 by pulleys 61 and 62 disposed at a starting point stop 65 and an end point stop 66, respectively.
5 and 66 are circulated in an annular shape, and the rope 64 is bent in an L-shape by bending pulleys 63A and 64B disposed in the bending portion 64 in the middle.

[0004] A two-loop bendable cableway shown in Fig. 5 (b) has pulleys 71, 72 between a start point and an end point stop 78, 79.
A first cableway for circulating the cable 73 by the
4 and 75, a second cableway for circulating the cable 76 is arranged in an L shape, and a pushing device 7 is provided between these cableways.
7A and 77B.

[0005] As shown in the figure, the horizontal distance between the upper and lower lines is maintained by the rope gauge in each of these cableways as shown in the figure.

[0006]

However, the above-mentioned articulated cableway according to the prior art has the following problems.

(1) The horizontal distance between the upper and lower lines is maintained by a rope gauge to prevent interference between the carriers, and the width of the passage area of the carriers (see FIG. 3) is large. For this reason, when setting up the cableway facilities, it was necessary to secure a vast passage area. (2) In the transport passage area, it is necessary to manage the plants and structures under the track so that they do not come into contact with the transport device. However, conventionally, since this area is large, it takes time to maintain it. (3) If an intermediate stop is installed in the cableway, the site for the building will be large and the construction cost will increase accordingly. (4) When used for indoor transport facilities such as indoor ski resorts,
The occupied area of the cableway facility with respect to the area of the building site increases, and the building space cannot be used effectively.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bendable cableway capable of reducing the width of a conveyed object passing area in the middle of the cableway in view of the prior art.

[0009]

A bendable cableway according to the present invention for solving the above-mentioned problems is provided at a rope which circulates in a loop between a starting point and an end point, and at one or a plurality of bends on the way. In the cableway consisting of up and down lines with a constant spacing in the horizontal direction at the starting or end point stop, between the starting point stop and any first bending device,
The constant horizontal interval is converted into a vertical height difference in which the objects to be conveyed by the cable do not interfere with each other, or a combination of the vertical height difference and the horizontal interval, and the first Between the bending device, or any second bending device from the end point stop than the first bending device and the end point stop, the height difference in the vertical direction in which the conveyed objects conveyed by the cable do not interfere with each other, or It is characterized in that a combination of a vertical difference in height and a horizontal interval is converted again into a constant horizontal interval.

Therefore, according to the bendable cableway having the above-described structure, the first and second bending devices have a vertical height difference between the upper and lower lines, so that the objects to be conveyed interfere with each other. The distance between the upper and lower lines in the horizontal direction can be reduced without performing the above operation, so that the width of the conveyed object passage area becomes significantly smaller than before.
