Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cableway system such as a lift that can be switched between high-speed operation and normal operation.

(Prior Art) In order to ensure the safety of getting on and off the lifts and the like that have been commonly used in the past, the conveyance speed cannot be made very high.

On the other hand, in order to enable high-speed operation, a cableway system has been developed in which the carrier is separated from the operating cable only when boarding and alighting.
Compared to general-purpose systems, cableway systems tend to have a more complex structure, are difficult to maintain and inspect, and are more likely to break down.

(Problems to be solved by the invention) The purpose of the present invention is to solve the above-mentioned conventional problems and provide a cableway system that not only enables high-speed operation with a simple structure but also can be used interchangeably with normal operation. .

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a plurality of cable loops that are operated close to each other, and a plurality of carriers that are attached to each cable loop at predetermined intervals. The present invention proposes a cableway system comprising a drive device that enables the plurality of cable loops to be operated by switching between driving each of the plurality of cable loops at a substantially constant speed and varying the speed in relation to each other.

(Function) By increasing the number of cable loops, the cableway system of the present invention can increase the resulting conveyance speed without creating a complicated structure, and as a result, a high-speed cableway system can be created with a simple structure. I can do it.

(Example) The cableway system of the present invention will be described below according to an example shown in the drawings.

FIG. 1 shows a cableway system according to the invention, comprising a plurality (two shown) of cable loops (+) (11
).

The cable loop (1) (as well as the cable loop (11)) is hung over the strut (20) and the pulleys (3) and (4) at both ends.

Further, a plurality of carriers (2) are attached to the cable loop (1) (same as the cable loop (11)) at predetermined intervals.

Furthermore, both cable loops (1) and (11) are driven by a drive device (not shown) including a prime mover such as a motor, and are operated by switching between driving at a substantially constant speed and driving in which the speeds of both are varied in relation to each other. made possible.

The operation of the cableway system of the present invention shown in the above embodiment ζ will be described below along with its operating method.

That is, since the cableway system of the present invention has a high-speed operating state and a normal operating state, each will be divided into two, and the high-speed operating state η) will be explained first.

For ease of explanation, Figures 2 to 4 show the carrier group (5) and (6) in the carrier (2) at a fixed position, and the carrier group (5) and (6) in a fixed position in the carrier (12). Carrier group (+5) in
Focusing on (u;), only these are illustrated.

First of all, Fig. 2 shows a passenger arriving at the platform (21) on the carrier group (6) of the cable loop (1) and at the terminal of the cable loop (11).
) Passengers are getting off at the alighting point (22) from the carrier group (15) of
1) is driven at low speed (speed when getting on and off).

Also, as is clear from Fig. 2, the carrier group (
6) is immediately after leaving the platform (21), while the carrier group (16) of the cable lube (II) is immediately after arriving at the platform (21).

The carrier group 5) of the historical rope loop (1) is the landing area (22)
Away from C-・Carrier group (+
5) is a state in which the vehicle has arrived at the drop-off point (22).

cj - Next, Figure 3 shows that the cable loop (1) is being driven at high speed (operating speed) ■2 at a sufficient distance from the carrier group (5) (6) or the landing area (21) and the landing area (22). It is in a state of being.

On the other hand, the cable lube (11) is still in the carrier group (15) (16).
Because it is located at the boarding area (21) and the alighting area (22), the speed is low (
It is driven by the speed when getting on and off) ■.

In this way, since the cable loop (1) is at high speed, when the carrier group (16) of the cable loop (11) leaves the vehicle Lm (2]), the carrier group (5) of the cable loop (1) Platform (21
), there is no major interruption in the transportation of passengers.

Next, Fig. 4 shows a state in which the carrier group (5) has arrived at the platform (21) and the carrier group (6) has arrived at the alighting area (22). )■.

It is driven.

On the other hand, the cable lube (II) is driven at high speed (operating speed) ■2 because the carrier group (15) (16) is far from the landing area (21) and the landing area (22).

In this way, since the cable roof (+1>) is at a high speed, when the carrier group (5) of the cable loop (1) leaves the platform (21), the carrier group (15) of the cable loop (11) moves from the platform (21). (21
), there is no major interruption in the transportation of passengers.

It is clear from the above that the passing E(2) has a cable loop (1
) and the carrier groups (+5) and (16) of the cable loop (11) are alternately arranged between the rows, so that passengers are transported almost continuously.

A graph showing the high and low speed changes of the above cable loop (IXII) is as shown in FIG.

The following is a design and operation example based on numerical values: <Design and operation example 1> Transparent section 1iiiI L=1200m operating speed
V p, = 4-i/sec boarding/alighting speed
V + = 2 vs/spc carrier spacing 12
m (2m/5ecX 6sec) Carrier group length
a = /l O(') m Number of carriers 33 (
400m/121m) Average conveyance speed V-work.

Design and operation example 2> Cableway distance L = 1200 m Speed during operation V 2 = = 4 m/sec Speed when getting on and off V t, = = 1 m/sec PG device interval
6m (1m/5ec 1) Carrier group (5) (6)
This was decided in such a way that the groups of carriers (15 x 16) of the cable loops (11) arrive alternately and the passengers are transported almost continuously.

That is, to explain design and operation example 1, if we find the value of a that makes them equal, it will be 400 m.

Next, from design and operation examples 1 and 2, the average transport speed (■) of the cableway system of the present invention in high-speed operation conditions. It is understood that this can be achieved at a sufficiently high speed compared to 2 m/see, which is the general transport speed of a general-purpose cableway system.

When the above-L is in a high-speed operating state or in a normal operating state, both cable loops (IXII) are each driven at a substantially constant speed by the drive device.

For example, by driving each carrier at 2 m/see, the conveying speed is slow, but since all the carriers (2) and (12) are used, the conveying capacity increases.

In other words, when there are many passengers, the vehicle can be set to normal operation mode, while when there are few passengers, the vehicle can be set to high-speed operation mode.

However, the carrier group (5) (6X15) (16) may itself have a landmark (for example, a colored ring),
In 21), an indicating device (for example, an arrow display, a signal display, opening/closing of a switchgear, etc.) interlocked with the drive device may be used to indicate which carrier (2) or (12) the passenger rides on. In this case, the carrier group (5) (6) (1501
6) means something virtual.

Next, in the above embodiment, there are two cable loops (1X11), but it is also possible to design three, four, etc.

In addition, in the above embodiment, attention was paid to the second group of carriers (506) of the cable loop (11) (the same applies to the cable loop (11)), and the method of operation using this was explained. As shown, four groups of carriers (506, 7, and 8) may be used for operation.

In this case, the high and low speed changes during one rotation of the cable loop (1) (same for the cable loop (11)) will be 4 cycles, which is more than the 2 cycles shown in Figures 1 to 6. Become.

(Effects of the Invention) The embodiments of the cableway system of the present invention are as described above, and the effects thereof are listed below.

(1) The cableway system of the present invention has the configuration described in the claims, and in particular, by increasing the number of cable loops, the resulting conveyance speed can be increased without creating a complicated structure. As a result, a high-speed cableway system can be constructed with a simple structure.

(2) The cableway system 11 of the present invention has the same configuration as above, and has a particularly simple structure, which facilitates maintenance and inspection and reduces the number of failures.

(3) The cableway system of the present invention has the same configuration as above, and in particular, since the drive device can switch between high-speed operation and normal operation, the cableway system of the present invention can be brought into an optimal operating state depending on the number of passengers.
