JPH0350060A - Spring-type diverging device for compound single line automatic circulating cableway - Google Patents

Abstract

PURPOSE:To perform the perfect switching of a cable gripping device and a conveyor by disposing two sets of vertically revolving movable rails opposedly and placing either set of movable rails in a spring shunt position when the other is in a passing position. CONSTITUTION:When a first movable rail 4 is in a passing position 4a shown by a full line, a cable gripping device 6 is induced being diverged from a rail 1 through the rail 4 and switched to a first branch rail 2. At this time, a second movable rail 5 is in a spring position 5b shown by a full line, so that the rail 5 and the cable gripping device 6 switched through the rail 4 do not interfere with each other. Moreover, as a passing space 9 is secured between the branch rail 2 and a second branch rail 3, a suspender 7a passes through without hin drance. When the rail 4 is turned vertically by 90 deg. around a supporting axis 4c to be placed in a spring shunt position 6b shown by a chain line as well as the rail 5 is vertically turned by 90 deg. around a supporting axis 5c to be placed in a passing position 5a shown by a chain line, the cable gripping device 6 passes safely to the branch rail 3 from the rail 1 through the rail 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rail branching device at a terminal of an automatic circulation cableway, in particular a double single-track automatic circulation cableway.

[Conventional technology 1] An automatic circulation cableway has a cableway that circulates a tow rope in an endless manner between pulleys installed at terminals (terminals) at both ends (the same applies hereinafter), and suspends a carrier. A device that grips a tow rope with a gripping device and moves a carrier along with the circulation of the tow rope for transportation, and is often used for sightseeing in mountainous areas and for transportation in ski resort areas. is widely known.

Conventionally, single-track automatic circulation cableways have been commonly used to operate passenger car-type or chair-type carriers using only one-strand guy ropes, but recently two-line guy lines have been used. A multi-track, single-track automatic circulation cableway has been proposed that uses cables to operate relatively large passenger cars to increase transportation capacity. In such a double-track single-track automatic circulation cableway, the cableway is usually guided by two rails to move inside the terminal.

Based on the mutual relationship between the support cables or rails and the carrier suspension machine, the following types of double single-track automatic circulation cableways have been proposed to date.

FIG. 5(A) shows a device in which a gripping device 81 is provided in the center and pushers 82° 82 for gripping a rope (not shown) are extended outwardly on both sides. One suspension 184 is hung down to suspend the carrier 85.

Such a system is described, for example, in French Patent No. 25259.
It has been proposed in Japanese Patent No. 81 as a "ropeway with two traction cables," and since the rope grip device 81 is located in the center, it will be referred to as an "inner type" here.

In FIG. 5(a), the rope gripping device 91 includes a rope gripping device 91a.

91b on both sides, and pressers 92 and 92 for gripping cables (not shown) are lined inside, and from the rope gripping machines 91a and 91b, one on the left and right is the suspension machine 9.
4.94 is hung down and the carrier 96 is suspended. This system has been proposed, for example, in Japanese Patent Application No. 62-295834 entitled ``Passenger Car Suspension Structure and Cable Holding Device for Double Track Automatic Circulation Type Cableway''. Since this method has the gripping ropes 1191a and 91b located on both outside sides, it will be referred to as the "external method" here.

In internal or external cableway equipment as shown in Figures 5 (a) and (b), a branching device is required to direct people from the main line rails to the side track rails in garages, etc. within the terminal. do.

However, even if the same two rails are used, in the case of general railways, the rails or branching devices installed on the ground and the vehicles rolling on top of these do not interfere with each other, so
The branching device can be freely designed. However,
In the case of suspended transportation vehicles, including the case of cableways, when branching, it is necessary to perform the branching so that the suspension machine does not interfere with the rails. In other words, in the case of the internal type shown in FIG. 5(a), either the rail 143a or 144a is
In the case of the external type shown in Fig. 5 (a), either rail 143a or 144a becomes an obstacle to the path of either suspension 1fi 94a or 94b, so it must be evacuated. There is a need.

A traverser-type branching device is a branching device that has been conventionally used in such suspended transportation vehicles. Figures 5(a) and 6(a) and 6(a) and 6(b) show examples of traverser type branching devices. In FIG. 6(A), a rail 140 having an end R, a rail 141 having an end S, and a rail 142 having an end T are fixedly installed. On the other hand, a traverser rail 143 having an end R'S' and an end RI
A traverser track 144 with IT' is suspended from the guide frame 145, 145 and along which the arrow 1
46 or in the opposite direction of arrow 147. In FIG. 6(A), the ends R and R' are connected, and the ends s and s' are connected, so that the rail 140 is in traversable communication with the rail 141 via the traverser rail 143. At this time, the traverser rail 144 is retracted to the side.

Next, as shown in Figure 6 (a), the traverser rail 143.14
4 along the guide frame 145.145 in the direction of the arrow 147, the ends R, R'' are connected, and the ends T, T' are connected, and the traverser rail 144 is moved from the rail 140 to the traverser rail 144. The traverser rail 143 is retracted to the side.

Such devices are used in suspension or straddle type mole rails, etc., and this design concept can also be applied to branching devices for double-track single-track automatic circulation cableways.

[Problems to be Solved by the Invention] However, this type of branching device requires large equipment, so although it is suitable for ceiling-suspended to mid-suspension transport equipment such as mole rails, it is not suitable for small to medium-weight transport equipment such as cableways. has the following drawbacks: i.e. traverser rail 143.144
requires space for shelter on both the left and right sides, and when moving the movable rails of the traverser-type branching device horizontally, it tends to be accompanied by others, making it difficult to connect the rails, or it is difficult to ensure the connection. Equipment for this purpose was also needed.
