Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope system for a two-line tow line single-line cableway in which a carrier is towed by two tow lines.

[0002]

2. Description of the Related Art Cableways are classified into single-track and double-track.

The single-line cableway is a cableway that is operated only by a towline, and the towline refers to a line that supports the weight of a carrier suspended from the line and also serves as a tow of the carrier.

On the other hand, the function of the rope is divided into a supporting rope for supporting the weight of the carrier and a tug for towing the carrier, and a ropeway composed of two different kinds of ropes is called a double-track ropeway.

Since the double-track cableway has no limitation on the height from the ground to the towed vehicle, it is suitable when, for example, a cableway is set up across a large canyon, and is suitable for the operation of a vehicle for 30 or more passengers. It's being used. However, in the case of a double-track type cableway, in addition to the towline, a very large diameter branch line is extended over a large span, so it is necessary to have pulleys, weights, tensioning devices, etc. that are suitable for it. There is a problem that the facility of the field and the supporting structure such as a steel tower become large.

On the other hand, with regard to the single-track type cableway, conventionally, 12
The single-branch single-track cableway, which operates vehicles up to the level of passengers, has become widespread and was simply called single-track cableway. But,
If the weight of the carrier is increased in order to increase the number of passengers, it becomes difficult to support and tow the carrier with a single tow line. Also, 1
In the single-line cableway, there are circumstances in which there is no choice but to set a height limit above the ground due to problems such as an accident in which the towline is cut or a rescue method is secured when operation stops. For this reason, a two-strand single-line cableway having two towlines is drawing attention.

By the way, in the single-track cableway, a rope device for guiding the rope according to the terrain is provided along the cableway. That is, in the place where it becomes concave, the upper surface side of the cord is pressed downward by the cord ring group of the pressure cord ring device, and in other places, the lower surface side of the cord is supported by the cord ring group of the receiving ring device. There is.

Conventionally, as such a rope device, a balance-type rope device has been generally used. The balance type rope device
A balance element having a plurality of horizontal axes, a plurality of beams swingable around the respective horizontal axes, and a plurality of loops supported by the respective beams, each beam having a center of the respective horizontal axis as a balance center. With this configuration, the load received from the towline is evenly distributed to the plurality of ropes.

FIG. 7 (a) shows an example of application of such a balance-type rope device to a two-support tug single-wire cableway.
Two support tows 14a, 14 for supporting and towing a carrier are provided with four-wheel rigging devices attached to the left and right sides (directions perpendicular to the support tows) of a bracket 41 fixed to a support structure such as a steel tower.
It has a structure in which b is separately guided and supported by two four-wheel rope devices.

Each of the left and right four-wheeled rope devices has the same structure as that of the one-towed rope single-lined four-wheeled rope device, and in this example, two ropes 47 are made into two-wheel beams 45 by the wheel shaft 46. The built-in two-wheel system is used as the minimum unit balance element. The first horizontal shaft 42 provided on the left and right of the bracket 41 includes a beam 43 parallel to the tow lines 14a and 14b, respectively.
The two-wheel device described above is swingably attached to the second horizontal shafts 44 provided at both ends of each beam 43. In this way, a group of two parallel rows of ropes, each consisting of four ropes 47, is formed, and each of the two ropes 14 in the single-line ropeway has two ropes.
It has a structure for guiding and supporting one of a and 14b.

This example is for a one-sided four-wheel system (eight wheels on each side), and the first horizontal shaft 42 and the front and rear second horizontal shafts 44 are made equal to each other to achieve balance. However, in general, a plurality of horizontal axes and beams are arranged so that each horizontal axis serves as a balance center, depending on the number and arrangement of the loops.
By combining in multiple stages, one-sided 6-wheel device, one-sided 8
A ring-ring device, and a rope device having 10 or more wheels on each side are configured.

[0012]

[Problems to be Solved by the Invention]
The basic configuration of the single-line tug rope system for a single-line ropeway is equivalent to one in which two balanced line rope devices for a single-line single-line ropeway are provided in parallel, and for each of the two tow lines. Has the effect of evenly distributing the load acting on each rope.

However, as a problem in the two-line tow cable single-line cableway, since the carrier is supported by two tow lines, an unbalanced load occurs, for example, when passengers gather on one side of the carrier to see the scenery. And the carrier may tilt, and a large difference may occur in the load received by the two tow lines. Therefore, each support line 1
In the structure in which 4a and 14b are supported separately, as shown in FIG. 7 (b), a difference occurs in the supporting load and the inclination of the beams 43 and 45 between the two parallel rows of the ring rings, and Receives a cross wind or when passing through the position of the rope device, a large horizontal sway or violent vertical vibration may occur.

Also, as in the case of the conventional one-strand single-line cableway device for a cableway, the beam and the cable loop are attached to one end of the first horizontal shaft provided on the bracket or the like of the support structure. A large bending moment acts on the first horizontal axis due to the load from the towline. Therefore, the central first
There is also a problem that the horizontal axis must have a high rigidity.

The present invention is intended to solve the above-mentioned problems in the prior art in providing a stable rope device exclusively for a two-strand single-line cableway.

[0016]

According to the two-strand single-line type cable rope device of the present invention, the center beam parallel to the towline is provided with respect to the first horizontal axis provided on the support structure. A shaft is swingably provided around a balance center, and balance elements each having a plurality of ropes are attached to the left and right of a second horizontal shaft provided in front of and behind the center beam to form two parallel rows of rope groups. It was done. The two tow lines supporting and towing the carrier are guided and supported by two parallel groups of ropes.

When it is difficult to dispose the beams constituting the balance element due to the large number of ropes, at least one of the second horizontal axes provided before and after the center beam has the two rows of rope groups. It is also possible to oscillate a second center beam positioned between them and to attach the balance elements to the left and right of a third horizontal axis provided in front of and behind the second center beam. In this case, it is necessary to suspend the bracket from the center beam of the second horizontal axis to which the second center beam is attached so that the center beam and the second center beam do not collide with each other.

The balance element referred to here is composed of a horizontal shaft which constitutes the balance-type rope device, a beam which can be swung around the horizontal shaft, and a plurality of ropes which are supported by the beam. , A smaller beam (a beam forming a balance element one step lower) that supports the rope or the rope is pivotally supported so that the horizontal axis serves as the center of balance in the swing of the beam. Further, the beam here is not limited to a single member beam, but includes a beam composed of a plurality of members forming a frame for holding the rope.

[0019]

FIG. 1 (a) illustrates the operation of the two-strand single-line type ropeway device of the present invention in order to explain the action of the simplest type, that is, four-wheels on one side and eight-wheels on both sides. FIG.

As shown in the figure, a center beam 3 is swingably attached to a first horizontal shaft 2 provided on a bracket 1 of a support structure 15, and two pieces projecting left and right at both ends of the center beam 3. The second horizontal axis 4 is composed of a two-wheel beam 5 as a balancing element, two wheel shafts 6 at both ends of the two-wheel beam 5, and two ropes 7 pivotally supported by the wheel shaft 6.
A wheel system is attached.

The second horizontal axis 4 serves as the center of balance of the two-wheel device by keeping the distance between the two wheel shafts 5 of the two-wheel beam 5 equal, and the first horizontal axis 2 is 2 in the center beam 3. The equilibrium distance between the two second horizontal axes 4 serves as the center of balance.

The balance on one side sandwiching the center beam 3 is as described above, but in the rope device of the present invention, the first horizontal axis 2, the center beam 3 and the second horizontal axis 4 are further added.
The left and right balance elements are coupled to each other via the, so that the load acting on the rope 7 can be equalized between the left and right balance elements.

That is, in the case of FIG. 7 (b) relating to the above-described conventional rope device, since the rope devices supporting the two supporting tugs 14a and 14b are independent and separate devices, the two ropes are supported. According to the vertical movement of the tow lines 14a and 14b, the left and right rope devices move independently and become unstable, while the tow device of the present invention has two support cords 14a and 14b. Since the left and right balance elements that support the center beam 3 share the same center beam 3, the inclinations of the two groups of ropes become the same, as shown in FIG. 1 (b), and the two tow lines 14a and 14b are synchronized. Therefore, horizontal swing and vertical swing of the carrier can be reduced, and stable operation can be achieved.

[0036]

According to the rope device of the present invention, the balance element is coupled through the center beam, and since the balance elements on the left and right of the center beam share the center beam, the carrier is tilted due to an unbalanced load. However, the inclinations of the two parallel groups of ropes are the same, and the loads acting on the respective ropes between the left and right balance elements are equalized.

By equalizing the load acting on each rope even between the left and right balance elements, it is possible to reduce horizontal swing and vertical swing, and it is possible to prevent the carrier from being detached due to the removal of the rope. It can be prevented and the safety of operation is secured.

With respect to the center beam which constitutes the rope device, each balance element composed of the rope, the horizontal axis and the beam is arranged with each horizontal axis as the center of balance, and the load from the two tow lines is searched. Since the entire wheel device is evenly shared, a stable string device is configured.

Like a conventional balance type rope device,
Since a large bending moment does not act on the first horizontal shaft provided on the bracket or the like of the support structure, the load on the first horizontal shaft as the support shaft is small, and it is easy to ensure the verticality of the rope.
