Description

Detailed Description of the Invention (a) Purpose of the Invention [Field of Industrial Application] The present invention relates to the field of cableways, particularly to the arrangement of cables and cable gripping machines of automatic circulation cableways using two guy cables. Construction and! l
This relates to the suspension structure of the I2 device.

[Prior art] An automatic circulation cableway has a cable that is looped endlessly between pulleys installed at terminals (stops) at both ends, and is circulated under tension, and can be attached and detached from the cable. A transportation system that transports large objects or objects by suspending the carrier from a rope gripping machine, and operating the carrier by gripping the rope at one terminal and releasing the rope at the other terminal. As is well known, it is a means of transportation.

In addition, the automatic circulation cableway has a large transportation capacity because it can frequently depart the carrier at short departure intervals, and also has the ability to adjust the departure interval depending on the number of transportation requests. As advances have improved driving speed, they have come to be used frequently for transporting skiers, sightseeing, etc.

However, in the single-track automatic circulation cableway that uses a single rope (branch cable), which has been widely used in the past, the form of the carrier is supported by the -branch cable, and it is towed for moving the carrier. Therefore, if large-scale equipment with increased carrier capacity is required, the required diameter of the tow rope will need to be large; The problem is that using cables is either technically impossible or economically unadvisable.

In such cases, it is advisable to use two relatively small-diameter cables to share the load instead of using one cable. This kind of technical thought has been around for a long time, for example,
It was proposed in Publication No. 3-5263 "Multi-wire Parallel Type Overhead Cableway", and although the technical content was not widely used in practical use, the seeds of this kind of technical idea have been around for a long time. can be known.

Recently, for example, French Patent Publication No. 252
Publication No. 5981 "Ropeway with 2 cables for transportation and traction"
There are the methods shown in Figures 1 (A) and (B) that were proposed in 2013.

That is, as shown in FIG. 5(A), a column arm 102 is fixedly attached to the head of a column 101 that is erected on the ground and extends in a shape that extends from both the left and right sides. The support arm 1
A pressure rope device frame 103 in the shape of a stirrup with a downward opening is fixed to the vicinity of the tip of the rope 02, and in the inner area 106 surrounded by the stirrup shape, there are two ropes placed horizontally in parallel. a towline or cable 104.104 and a cable 104;
Equipped with pressure cable rings 105 and 105 compatible with 104°. Although the support method of the pressure cable ring 105.105 is abbreviated in the drawing, in reality, the pressure cable ring 105.1
05 is each composed of a plurality of wheels, has a normally used balanced structure, and is of course supported by the pressure cable device frame 103 with pins.

On the other hand, as shown in FIG.
2. are installed side by side, and each grip line II! 11
2, 112, 112, 112 has grip portions 113.113° 113.113 which protrude outward alternately on the left and right sides, and grip portions 113.113° 113.113. Each of the cables 104 or 104 is gripped by the cable.

Using such a gripping device 110, FIG. 5(A) is again used.
As shown in FIG.
06, guided by cables 104, 104. The gripping device 110 has a hanging ta 114.
is suspended, and [115 is suspended from the suspension 11114.

[Problems to be Solved by the Invention] However, such conventionally proposed devices have the following drawbacks.

That is, first, as can be seen from FIG.
, 112 are arranged in parallel in series with respect to the moving direction of the carrier, so that the length of the gripping device is L' as shown in the figure.
) must be long. When the rope gripping device 110 having such a length L' travels on a cableway track, the rope gripping device 1
In order for 10 to operate smoothly, it is necessary to have some kind of follow-up function, that is, a balance or free function, and if it does not have such a function, the
There is a risk that the cable may be damaged by bending or the gripping device may be subjected to an unusual load. However, a cable gripping machine with such a function has a complicated structure and is uneconomical because it is specially designed to be used only for an automatic circulation type cableway using two tow lines.

The second problem is the structure of the mechanical equipment installed at cableway terminals (stops).

Generally, in automatic circulation type terminals, mechanical devices for moving the carriers are installed on the departure side of the carriers, such as a device for regulating the interval between the carriers, a device for accelerating and pushing the carriers, a device for gripping the carriers, etc. On the arrival side, devices such as a device for firing lightning and a device for decelerating the carrier are installed, as well as a device for inspecting the quality of these operations. These devices are arranged in series along the carrier passage route inside the terminal, but as the operating speed of the cableway has recently increased, the length of the acceleration/deceleration section described above has become longer, and this has caused Naturally, the mechanical equipment required for this purpose has become quite large.

In the case of a single-track automatic circulation type cableway, only one set of mechanical devices for moving the carriers is provided, corresponding to the -strip cable, but when two-strip cables are used, For this purpose, two sets must be established. Generally, such mechanical equipment is installed by being fixedly suspended from an elevated beam inside the terminal or a ceiling beam of the terminal building, but in the case of conventional equipment, it is installed as shown in Figure 5, for example. It happens. That is, a mechanical device frame 123 is fixedly suspended below a beam 122 provided in the terminal 120, and the gripping device 110 and the passenger car 115 move from the paper slot toward the paper spine in the figure. And gripping device 1
10 and P vertical axis 114 are arranged to pass within the inner area 124 of the mechanical device frame 123, and are arranged to provide the necessary operational mechanical devices for the left and right rope grip machines 112, 112 and 112, 112. are the left and right mechanical device installation areas 125
, 125. Needless to say, the said mechanical devices must also be equipped so that the left and right hand grips 111112.112 and 112.11.2 operate correctly in the required order as the vehicle progresses, and the left and right height levels also match exactly. However, the mechanical equipment installation area 125.1
In the conventional type in which the 25 is divided into left and right, it is necessary to install and adjust the left and right mechanical devices in unison.
Moreover, it has the drawback that it requires a lot of effort to maintain.

This invention was made in view of the above-mentioned circumstances, and it does not cause strain on the rope gripping device or the rope gripping machine due to changes in the vertical bending curve of the cable in the cableway track, and it also prevents strain on the cable. There is no risk of refractive damage, there is no need to use a special design for the gripping device, it is easy to accurately adjust and maintain the relationship between the mechanical devices for transporting vehicles at the terminal, and the gripping device is easy to adjust and maintain. It does not interfere with the passage of the device,
The purpose of this invention is to provide an automatic circulation cableway using two tow ropes that can be operated safely.

(B) Structure of the Invention [Means for Solving the Problem] In response to this purpose, the automatic circulation cableway using two strands of the present invention has two strands that are stretched and circulated between terminals at both ends. It consists of a branch tow rope, a rope gripping device for gripping the two branch tow ropes, a suspension machine suspended from the rope gripping device, and an l112 device suspended from the suspension machine, and the rope gripping device comprises: In an automatic circulation cableway facility in which a rope gripping or lightning action is performed at the terminal and the cable is moved and the carrier is operated for transportation, the rope gripping device is disposed at an outer position of each of the two tow ropes. The suspension machine includes a suspension beam which is pivotally connected at both ends to each of the rope gripping machine blocks and is swingable in the forward and backward direction of movement of the carrier, and the suspension beam. A suspension hanger is pivotally connected to the carrier so as to be swingable in a direction perpendicular to the travel of the carrier, and the carrier is suspended from the suspension hanger. It is a feature.

Hereinafter, details of the present invention will be explained with reference to the drawings showing one embodiment.

FIG. 1 shows the relationship between the strut of the present invention, the gripping device, the suspension machine, and the carrier. A strut 1 is erected on the ground, and a strut arm 2 is fixedly attached to the head of the strut 1 so as to extend on both left and right sides. Since the strut arms 2 are symmetrical with respect to the center of the strut 1, one is omitted in the figure. A pressure cable device hanger 3 is fixed near the tip of the support arm 2 and extends downward.

Next, the tow rope, that is, the cable 4.4, is located at a symmetrical position on both sides of the pressure line device hanger 3 as a passage path, and correspondingly, the pressure line ring 11.11 is also located in the pressure line device hanger 3. They are arranged at symmetrical positions on both sides of the hanger 3. Although the support method of the pressure receiving cable rings 11.11 is abbreviated in this figure, in reality, the pressure receiving cable rings 11.11 each have a balanced structure composed of a plurality of shafts. Of course.

That is, as shown in FIG. 2, first, the pressure receiving cable ring 11.
11 are pivotally connected to the receiving cable wheel beam members 13a, 13a through pins 12 and 12, respectively, and constitute a pressure receiving cable wheel beam 13. Similarly, each of the other pressure receiving cable rings 11, 11, . . . constitutes a receiving cable ring beam 13, 13, 13, in pairs. Next, the receiver wheel beams 13.13 are each pivoted to the balance beam members 15a, 15a using pins 14.14 to form the balance beam 15, and similarly the other receiver wheel beams 13.13 are each connected to the balance beam members 15a, 15a using pins 14.14. 14.14 is used to pivot the balance beam members 15a, 15a to form a balance beam 15. Balance beams 15.15 are then arranged on both sides of the pressure cable hanger 3, and the bins 16 are placed between them.
They are pivoted through each other, and are thus assembled in a balanced manner. The configuration of each of the balanced beams 15,15 is equivalent to that of a conventional standard balanced pressure line system.

Here, the balance beam members 15a and 158 of the balance beam 15.15 near the pressure rope device hanger 3 are connected using a connecting member 17.17, for example, with a bolt or the like, thereby forming the double pressure rope device 10. ing. By connecting the left and right balance beam members 15a, 15a with the connecting member 17.17 in this manner, the balance beams 15.15 are made to perform synchronous equilibrium or oscillating motion integrally around the bin 16. The left and right cables 4, 4 are balanced and supported while maintaining their parallel positions.

Next, the gripping device 20, suspension device 24, and carrier 29 for transportation will be explained with reference to FIGS. 1 and 3.

In FIG. 1, the tethering device @20 consists of tether blocks 21, 21 arranged opposite to each other in order to grip two cables 4.4, respectively. As shown in the plan view of FIG. 3, each rope gripping machine block 21.21 is provided with rope gripping machines 22.22 on both sides, an intermediate block 23 is disposed in the middle, and these are fixedly fixed in parallel or fixed in a constant manner. It has a configuration in which they are connected in parallel under the constraint conditions of . Each rope grip machine 22.
22° 22.22 have gripping parts 22a, 22a, respectively.

22a, 22a extend inwardly and grip the cable 4 or 4.

Next, the suspension machine 24 includes a suspension beam 26 and a suspension hanger 28.
It is becoming more and more.

First, below the intermediate blocks 23.23, both ends of a suspension beam 26 are pivoted at respective bins 25.25, and the suspension beams 26 are connected to the respective rope gripper blocks 21 and 2.
1 are connected. and said bottle 2. r
, 25 are arranged on the same virtual axis,
Therefore, the suspension beam 26 and the components suspended downward from the suspension beam 26 are pivoted so as to be able to pitch or pitch back and forth in the traveling direction of the carrier 29 about the bins 25, 25.

Next, the upper end of a suspension hanger 28 is pivotally attached to the vicinity of the center of the suspension beam 26 by a bin 27.
A carrier 29 is connected and suspended from the lower end of the . The suspension hanger 28 is pivoted so that the carrier 29 can swing left and right, that is, roll. Although not shown in this figure, if necessary, a known shock absorbing device that has been used as a standard may be interposed between the suspension hanger 28 and the carrier 29. Of course.

In addition, the rope grip machine blocks 21 and 21 that constitute the rope grip device 20
There is a conventionally used device for gripping a single-track automatic circulation cableway operated using a single tow rope, such as Utility Model Application Publication No. 57-70996 "Cableway gripping machine", or, It is possible to use almost the basic configuration of the device proposed in Japanese Patent Application Laid-Open No. 59-223556 ``Automatic Circulating Cableway Cable Gripping Machine'' and the like.

Next, FIG. 4 shows the arrangement of mechanical equipment at the terminal necessary for cableway operation.

Here, the mechanical device 36 refers to a device for roping or rigging the rope, a device for accelerating the departure or deceleration of the carrier on arrival, and the like.

Conventionally, such mechanical equipment 36 has generally been installed with a mechanical equipment support frame made of beams and beams erected from the floor within the terminal, or suspended from ceiling beams of the terminal building. It is.

The system shown in FIG. 4 uses a beam 32 which is supported by pillars (not shown) on the floor 31 of the terminal and is positioned overhead, as described above. is fixed and extends downward. FIG. 4 shows the beam 32 and mechanical equipment hanger 33 shown in the front view. Similarly, a plurality of beams 32.32. . . . and mechanical equipment hangers 33, 33° . . . are equipped. The mechanical device frame 34 is shown in cross section in FIG. 4, and is a long member made of, for example, a square steel pipe and extending from the paper slot to the back of the paper in the direction of movement of the carrier 29. , the plurality of mechanical device hangers 33, 33 . It is suspended and fixed by .... The tether block 21 . 21 of the tether 20 is connected to the machinery hanger 33 , 33 , . . . and the machinery frame 3 .
The left and right of 4 are the passing positions, and as mentioned above, the suspension beam 2
6. A hanging hanger 28 and a carrier 29 are suspended from this.

Here, the mechanical device 36 for moving the carrier is located within a range that does not interfere with the rope gripping machine block 21.21 and the suspension beam 26, that is, within the mechanical device installation area 35 shown by diagonal lines, and within the movement of the carrier 2-9. It is fixed or suspended on the mechanical device frame 34 along the direction. Therefore, the mechanical device 36 is constructed by forming a pair of left and right rope gripping machine blocks 21 or one mechanical device having the same configuration for the rope gripping machine block 21 back to back with the mechanical device hanger 33 at the center. It is unique in that it is supported by a frame 34, and unlike conventional devices, the mechanical devices for the left and right rope gripping machines are not divided into left and right hands without regard to each other.

[Function] As shown in FIG. 1, the pressure rope device hanger 3 fixed near the tip of the strut arm 2 is in a downwardly extending position. A dual pressure line device 10 is equipped in a balanced manner. As a result, the pressure cable rings 11, 11, . . . are located on both sides of the pressure cable device hanger 3 as shown in FIG.
．． 4 is the pressure receiving cable ring 11.11. ...and 11.11.
Each is supported by...

FIG. 1 shows a state in which the carrier 29 is passing through the position of the support column 1, and the gripping parts 22a, 22a and 22a, 22a of the left and right rope gripping machine blocks 21, 21 hold the ropes 4 or 4, respectively. The cable is gripped and operated with the movement of the cable 4.4. Since the rope gripping machine block 21° 21 is located outside the cables 4, 4, the pressure rope device hanger 3 and the multiple pressure rope device 1
It can pass through without interfering with 0. Further, the connecting member 17.17 of the above-mentioned double pressure cable rig @10 is a connecting means for integrally periodically moving the left and right balance beams 15.15, but it is of the conventional type in which a suspension hanger passes through the center. However, in the case of the present invention, the connecting member 17.17 has a simple structure and does not become an obstacle to the passage of the rope gripper block 21.21.

Next, at the bottom of the rope grip machine block 21.21 is a bin 25.2.
Both ends of the suspension beam 26 are pivotally connected at 5, thereby determining the mutual spacing between the left and right rope grasper blocks 21.21, and the bins 25.25 are arranged so as to be included on an imaginary coaxial line. Therefore, the configuration of suspension beam 26 or less, 1
The rope hanger 28 and the carrier 29 are attached to the bin 25.
It is clear that it is swingable in the forward and backward directions, that is, pitching, about the center of 25. Therefore, uphill navigation of the carrier navigation,
It goes without saying that both downhill operations can be used in the same way as conventional carrier structures.

Next, a hanging hanger 28 is attached to the hanging beam 26 with a bin 27.
are pivotally connected, so that the hanging hanger 28 and the carrier 29 can swing left and right around the bin 27, that is, the carrier 2
9 can be rolled and swung freely. Therefore, even when wind pressure load due to cross wind is applied to the carrier 29, the carrier 29
This is absorbed by the horizontal tilting of 9, and, for example, the tendency of one of the rope gripping machine blocks 21 to lift up from the pressure-receiving rope ring 11 in FIG. 1 does not occur. Similarly,
Even if the left and right cables 4.4 are unevenly bent midway between the tension spans of the cables 4, 4, the suspension hanger 28 and the carrier 29 are maintained in a state of hanging vertically downward.

However, if the center of the bin 27 undergoes significant rolling movement, it will become unstable, so if you want to limit this,
It is also possible to utilize the structure proposed in the January 27, 1988 patent application ``Rolling shock absorber for cableway carrier''.

Next, inside the terminal 30, the beam 32°32.3
2. Mechanical equipment hanger 33.33. The mechanical device frame 34 is fixed to the mechanical device frame 34 through the mechanical device frame 34, and the mechanical devices 36 corresponding to the left and right rope gripping machine blocks 21, 21 are integrated back to back and are installed within the range of the mechanical device installation area 35. 21, 21 and suspension beam 26.
The vehicle passes through the vehicle without interference, and the necessary operations or operations for transporting the vehicle, such as gripping, lightning, acceleration, or deceleration, are performed.

Here, the operations or operations for the departure or arrival of the left and right rope gripping machine blocks 21.21 include those that require left and right simultaneousness, those that set a left and right time difference, and those that require left and right synchronization. Although the same height level must be maintained, in the present invention, the left and right parts can be mounted on the same mechanical device frame 34, so the configuration set in advance can be precisely manufactured as a factory assembly with a high level of manufacturing control. However, for on-site work, it is only necessary to install mechanical equipment hangers 33.33. ...
The mechanical device frame 34 and the mechanical device 3 equipped thereon
By simply performing the installation work 6, it is possible to assemble a precise mechanical device 36 for transporting a carrier that satisfies the desired performance. On the other hand, in the conventional device, the left and right mechanical devices for the left and right rope grippers are separated completely unrelatedly in order to pass the suspension hanger, so in order to ensure the height level of the left and right mechanical devices, etc. However, this had the disadvantage of having to be carried out on-site with poor working conditions.

(c) Effects of the invention The following effects can be obtained by employing the automatic circulation cableway using the double-branch towline of the invention.

(-) First, because the gripping device is separated into a pair of gripping trowel blocks on the left and right, the length L is shorter than that of the conventional device, and therefore the vertical bending curve of the cable in the cableway track is reduced. Even if the gripping device does not have a special free or balanced follow-up mechanism in response to changes in do not have.

(d) As mentioned in the previous section, there is no special design required for the gripping block that constitutes the gripping device;
The basic configuration of a cable gripping device for a single-track automatic circulation cableway using a strip can be used as is. This results in the standardization of component parts, which is of great benefit not only to the supplier of the device, but also to the consumer, as they can receive replacement parts economically and quickly.

(3) The mechanical device for moving the carriers at the terminal must be arranged in pairs, one set each corresponding to the left and right cables, and these must be correctly arranged in a predetermined relationship. Because they are integrally fixed or suspended from the machine frame, it is easy to precisely adjust and maintain their interrelationships.

(4) Similarly, for the dual pressure cable device used at the support position, the basic configuration of the standard pressure cable wave δ used in conventional single-track automatic circulation cableways can be repurposed by arranging two sets in parallel. , and by only connecting using a simple connecting member, it is possible to create a structure that does not require support for the passage of the gripping device.

(5) Although it is necessary to add a suspension beam to the conventional standard configuration, the structure of the gripping device, suspension machine, and carrier is structured so that pitching and rolling movements are possible with the bin. This is similar to the case of carriages on conventional single-track automatic circulation cableways, which allows for safe operation without imposing excessive loads on the equipment or cables.

It has excellent effects such as these, and has greatly contributed to the development of automatic circulation cableways using double-branched tow lines.
