Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating cableway device used for transporting people and things at, for example, a ski resort, an amusement park, a mountain sightseeing spot, a mining site, and a construction civil engineering site.
More specifically, a carrier such as a gondola or a lift is hung via a gripping device on an endless annular rope that is erected so as to connect two points of a start point and an end point and is circulated and moved. It relates to a thing that makes two points travel in an alternating manner.

[0002]

2. Description of the Related Art A circulation type cableway device of this type is shown in FIGS.
The following are typical representative examples. The circulation-type cableway device 50 shown in the figure is basically laid so as to connect a starting point portion (for example, a platform at the foot of a mountain) S that serves as a stop and an end point portion (for example, a landing at the top of a mountain) E. The endless annular rope (wire rope) 12 that is circularly moved so as to circulate between the start point S and the end point E thereof.
And a plurality of transporters 3 suspended from the forward path portion 12A and the return path portion 12B of the cord 12 via the gripping rope device 20.
It is equipped with 0, 30, and.

When viewed from above, the cord 12 is installed straight along a straight line connecting the starting point S and the end point E, and the line 12 is guided and supported on the straight line. A plurality of columns 60 as shown in FIG. 8 are erected at a predetermined interval. A horizontal beam 62 is symmetrically arranged on the upper portion of the support column 60. Pulleys 64, 64 for supporting the rope 12 are supported on the outer surfaces of both sides of the horizontal beam 62 with the pin shaft supported in a state of protruding outward. ing. Therefore,
The rope 12 moves so as to slide on the pulley 64, and as the rope 12 moves, a plurality of the ropes 12 are suspended from the gripping device 20 at specific positions on the rope 12 with a required space. The carrying devices 30, 30, ... Of are sequentially conveyed to the start point S and the end point E.

In this case, the gripping rope device 20 for fixing and suspending the carrier 30 to the rope 12 holds the rope 12 from above so as not to interfere (collide) with the pulley 64 and the lateral beam 62. , And the entire gripping device 20 projects outward,
In the forward path portion 12A and the return path portion 12B, the gripping device 20 is directed in the opposite direction.

At the start point S and the end point E where the carrier 30 is conveyed, the cord 12 is wound around the pulley 42 as shown in the end point E in FIG. While the direction of movement is reversed, the gripping device 20 is released at a point P in front of the pulley 42, and the carrier 30 is detached from the cord 12. At the time of this detachment, the carrier 30 is guided by the rails 44 and, if necessary, decelerated to a running speed (for example, 0.3 m / s) in the field by a decelerating and pushing device such as a tire type speed reducer, and then the in-field pushing device ( (Not shown)
It is rotated twice and sent to the departure side. Then, on the departure side, if necessary, the accelerating device such as a tire type acceleration device accelerates until the moving speed of the cord 12 is reached, and when the cord 12 and the gripping device 20 are in the same position, the gripping device is moved. 20 is put in a gripping state (point Q), the carrying device 30 is conveyed again from the end point portion E to the start point portion S along with the cord 12, and thereafter, at the start point portion S and the end point portion E, the same operation as described above is performed. Is repeated.

[0006]

By the way, in a ski resort or the like in which the above-mentioned circulation type cableway device is to be constructed, there is an obstacle on the straight road connecting the starting point S and the ending point E. Alternatively, due to topographical reasons such as it is difficult to erect the pillars 60 for supporting and guiding the ropes 12 on the straight roads, the ropes 12 forming the transport path of the carrier 30 are linearly drawn in a plan view. It may not be possible to turn. In such a case, for example, as shown in FIG. 10, the rope 12 is bent or bent so as to project from the straight road in the left-right direction, in other words, to avoid obstacles or the like existing on the straight road. It is conceivable to arrange the cord guide mechanisms 72, 71 composed of pulleys 66 and the like so as to be inscribed in the protruding portions H, G of the outward path portion 12A and the return path portion 12B of the cord 12, respectively.

However, in the above-mentioned conventional circulation-type cableway device 50, the entire carrier 30 is rotated by 1/2 at the start point S and the end point E, and the gripping device 20 is moved forward of the cord 12. 12A and the return path portion 12B, respectively, so that the gripping device 20 is directed in the opposite direction between the outward path portion 12A and the return path portion 12B of the cord 12, so as described above. Under the condition that the line 12 is curved or bent and the projecting portions G and H are inscribed with the line guide mechanisms 71 and 72, as shown by phantom lines in FIG.
The gripping device 20 collides with the rope guide mechanism 72 or 71 in either the forward path portion 12A or the return path portion 12B, and the carrier 30 cannot be transported.

Therefore, with the structure of the conventional circulation type cableway device, it is impossible to bend the transport path of the carrier in the left-right direction in a plan view, which limits the cableway designing plan at a ski resort or the like.

In view of such a point, the present invention bends and draws the rope so as to jut out in the left-right direction in a plan view at a place where the conveyance path of the carrier cannot be linearly set due to the presence of an obstacle or the like. Under the circumstances, it is possible to reasonably avoid the interference between the gripping device and the rope guide mechanism and the like, and to provide a circulation type cableway device which can increase the degree of freedom in designing a cableway in a ski resort or the like. With the goal.

[0010]

In order to achieve the above-mentioned object, the circulation type cableway device according to the present invention is basically laid so as to connect a starting point portion and an end point portion like the conventional one. It is provided with an endless annular rope that is rotated and circulates so as to circulate between them, and a transporter that is suspended at a forward path portion and a return path portion of the rope via a gripping device. The rope is bent and routed so as to jut out in the left-right direction from a straight road that connects the start point portion and the end point portion in plan view, and is extended to the forward portion and the return portion of the rope, respectively. The cord guide mechanism is arranged so as to be inscribed, and the gripping device is arranged so as to project to the projecting side of the cord in a plan view in both the outward path portion and the return path portion of the filament, It is characterized in that the posture of the gripping device or the carrier is adjusted at the start point portion and the end point portion.

In such a circulation type cableway device of the present invention,
As the rope guide mechanism, a single pulley may be inscribed in the overhanging portion of the rope, but a pulley that supports the vertical load of the rope and a pulley that supports and guides the rope in a horizontal direction are provided. It is more desirable that they are alternately arranged at a predetermined interval.

As means for adjusting the attitude of the gripping device or the carrying device at the starting point and the ending point, the carrying device is fed back from the arrival side to the departure side by a switchback method, or an arc shaped feeding. Examples thereof include one in which the gripping device and the carry device are relatively rotated along the path to move the carry device in parallel while always pointing in the same direction, and one in which the carry device is laterally moved from the arrival side to the departure side by a pusher or the like.

[0013]

In the circulation type cableway device according to the present invention having the above-mentioned structure, the posture of the gripping device or the carrier is adjusted at the start point and the end point, and the gripping device is set at the forward part of the cord. In any of the return path part, it is designed to project to the projecting side of the rope in a plan view, so that the gripping device collides with the guide path mechanism in both the forward path part and the return path part of the rope when carrying the carrying device. Instead, the carrier can be transported safely and smoothly.

By doing so, the rope can be bent and drawn so as to jut out in the left-right direction in a plan view in a place where the conveyance path of the carrier cannot be set linearly due to the presence of obstacles or the like. Even under these circumstances, the interference between the gripping device and the line guide mechanism can be reasonably avoided, and the flexibility of the cableway design plan in a ski resort or the like can be increased.
