Description

[Detailed Description of the Invention] (a) Purpose of the Invention [Field of Industrial Application] The present invention relates to a pressure cable device for receiving or supporting cables in the field of cableways, and particularly for cables near stations. The present invention relates to a one-sided swing type pressure rope device suitable for cases where it is necessary to restrict the vertical floating of one of the cables guided and supported by the pressure rope device in a strut or the like.

[Prior Art] In cableway equipment, there are generally two types of pressure cable devices used to support and guide circulating cables: a fixed type and a balanced type.

Among these, the fixed type is one in which the slopes of the entrance and exit sides of the cable to the pressure cable device are set in advance by design, and the pressure cable ring is fixed in accordance with this.
It is used for intersecting cableways that have separate stationary cables.

On the other hand, a balanced pressure line device has a self-balancing function so that the load and bending angle of each pressure line loop are equalized even if the slope of the cable entry and exit sides changes. It can follow changes caused by operating conditions, and is extremely commonly used for fixed or automatic single-track circulation cableways.

FIG. 5 shows a well-known balanced pressure rope device 1.
FIG. 2 is an explanatory diagram illustrating the principle in the case of an eight-wheel pressure rope device.

In Figure 5, bracket 2 is in the fixed position.
A first balance beam 4 is pivotally attached to the holder by a pin 3, and pins 5 are attached to both ends of the first balance beam 4.
a, 5b respectively second balanced beams 6a, 6b
is pivoted. Further, at both ends of each second balanced beam 6a, 6b, a third balanced beam 8a, 8b,
8c and 8d are pivotally mounted. In this way,
The third equilibrium beam, which is the final order equilibrium beam in this case,
Each of the balance beams 8a, 8b, 8c, and 8d has two pressure receiving cable rings (in this case, pressure cable rings) 10.
a, 10b, 10c,...10h are pins 9a, 9
They are rotatably pivoted at b, 9c,...9h.
In this way, pressure receiving cable rings 10a, 10b, 10
The cables 11 are supported by pressure cables by cables c, . . . 10h. In this drawing, cable line 11 is
is shown as a straight line, but actually there is a slope on the introduction side and the exit side of the cable 11, and the cables 11 work together to equalize the load and bending angle of all the pressure cable rings. and operates in equilibrium.

The balanced pressure line device has such a simple configuration,
It is very commonly used in fixed or automatic single-track circulation cableways because it follows various operating conditions well.

[Problems to be Solved by the Invention] However, it is difficult to use such a balanced pressure cable device for a support attached to a bus stop (usually the first support or the last number support) installed near the entrance to the stop. If this happens, the following problems will occur.

Figure 6 A, B, and C are explanatory diagrams showing the state when the conventional balanced pressure cable device 1 is used as a supporting column attached to a station in an automatic circulation cableway. The case of a pressure cord device is shown.

In FIG. 6A, a support post 23 attached to the stop is erected near the stop 20, and the balanced pressure cable device 1 is installed on this support. The cables 11 extend from the cableway to the plurality of pressure cable rings 10a, 1 of the balanced pressure cable system 1.
0b, . In addition, inside the bus stop 20, there are cables 11
Elevated rails 22 are fixedly installed to guide the carts wandering around. In addition, if a predetermined relative position is not always maintained between the elevated rail 22 and the introduction position of the cable 11, the grasping and roping movements of the carrier, the preceding and following carriers, and the movement of the cables 11 to the elevated rail 22 may occur. Since the entry and exit operations of the carrier cannot be performed correctly, the introduction position or height of the cable 11 into the stop 20 must be maintained accurately at all times.

FIG. 6A shows a case where the carrier is in a steady state far away from the cableway line outside the drawing width, and the cable 11 is introduced horizontally into the station 20 from the balanced pressure cable device 1.

FIG. 6A shows a case where the carrier 24a enters within the width of the cableway line 26 of the balanced pressure cable system 1. At this time, due to the weight of the carrier 24a, the pressure cable ring 1 of the balanced pressure cable device 1 is brought closer to the cableway track 26.
The wheel pressure loads such as 0a and 10b are relatively reduced compared to the wheel pressure loads such as pressure rope rings 10g and 10h near the mooring site 20, and therefore, the balanced pressure rope device 1 has a balance function that reduces the overall load. It rotates in the direction of arrow 25a. As a result, the cable 11 moves from the steady state indicated by the dotted line to the vehicle 24a, as indicated by the solid line in this figure, and rises near the stop 20, so that it is introduced horizontally into the stop 20. The cable 11 to be installed will be introduced while transiently floating upward.

FIG. 6C shows a case where the carrier 24b has advanced toward the stop 20 of the balanced pressure cable apparatus 1. In this case as well, depending on the weight of the carrier 24b, the pressure cable rings 10g, 1
The wheel pressure load such as 0h is relatively reduced than the wheel pressure load of the pressure receiving cable rings 10a, 10b, etc. near the cableway track 26, and therefore the balanced type pressure receiving cable device 1 has an overall balance due to its balancing function. It rotates and oscillates in the direction of arrow 25b. As a result, the cable 11 rises from the steady state indicated by the dotted line near the cableway track 26 and descends at the carriage 24b position, as indicated by the solid line in this figure, and is introduced horizontally into the stop 20. The cable 11 to be removed is temporarily displaced downward and introduced.

In this way, when the conventional balanced type pressure-receiving cable device 1 is used for the support column 23 attached to the parking area, the position of the cable 11, which should originally be maintained at a predetermined position, is displaced vertically,
As a result, there was a problem that had an adverse effect on the approach, exit, grip, and release of the carrier, the preceding carrier, the following carrier, and the like.

Moreover, the effects of this phenomenon are further amplified due to the use of multi-wheel pressure cable devices due to the steep slope of the cableway, the increase in transient shock due to increased operating speed, and the increase in weight due to the increased capacity of the carrier. The impact of this has become impossible to ignore, and improvements are desired.

On the other hand, when a balanced type pressure receiving cable device as shown in Fig. 5 was used for a support in a cableway line, there was a problem of excessive swinging in both directions due to a phenomenon similar to the above. Utility model registration No.
No. 1542945 (Utility Model Publication No. 58-37723) ``Safety Structure of Cableway Pressure Cable Device'' proposes a technology to attenuate and control excessive swinging using shock absorbers on both sides of the balance pin of a balanced pressure cable device. and has been put into practical use.

However, this technique limits the bidirectional swing of the balanced pressure cable system, and is therefore suitable for use in cableway lines. It could not be applied in cases where the other party wanted to be free.

This invention was made in view of the above-mentioned circumstances, and even when operating on a steeply sloped track at high speed, it is possible to prevent the vertical positional floating displacement of the height of the cable introduced into the stop due to the movement of the carrier. It is an object of the present invention to provide a pressure line device that can avoid such problems.

(b) Structure of the invention [Means for solving the problem] In response to this purpose, the single swing type pressure receiving cable device for a cableway of the present invention has one end pivoted at a fixed position, and the other end pivoted at a fixed position. The area consists of a swinging beam supported at a fixed position via a fluid pressure cylinder connected to a fluid pressure source with a constant pressure, and a set of balance beams pivoted near each end of the swinging beam. , each of the balanced beam groups consists of a plurality of balanced beams from the first balanced beam to the Nth balanced beam, and the next balanced beam is sequentially pivoted to the previous balanced beam. A plurality of pressure-receiving rope rings are pivotally attached to the final balance beam in the group of balanced beams, and the pressure-receiving rope rings support and guide the cables, and the hydraulic cylinder is It is characterized in that one end is pivoted to a fixed position and the other end is pivoted to the swing beam.

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

The embodiments shown in Figures 1 and 2 A and B are as follows:
A pressure cable device using eight pressure cable rings, that is,
This shows the case of a device for guiding refraction in a concave upward direction when viewed from the side. In addition, in FIG. 1, in order to avoid the lines in the drawing from becoming complicated and unclear, the cables 61 are shown without a bending angle, that is, in a straight line.

First, in this embodiment, the swing beam 31 is a slightly elongated member made of a rectangular hollow tube material, and protrusions 32, 32 are protruded and fixed upward near one end 31a, and near the other end 31b. Projecting portions 33, 33 are fixedly projected upwardly.

The protrusions 32, 32 are pivotally connected to a bracket 35 by a pin 34, and the bracket 35
is fixed to the strut arm 36 in a fixed position.

On the other hand, the protrusions 33, 33 are pivotally connected to a piston rod 39 of a hydraulic cylinder 38, which is an example of a fluid pressure cylinder, by a pin 37.
The hydraulic cylinder 38 is pivotally connected to a bracket 41 by a pin 40. and the bracket 41
is fixed to the strut arm 42 in a fixed position. As will be described later, the piston rod 39 is telescopic when pressure oil is supplied to or discharged from the hydraulic cylinder 38. Therefore, when the piston rod 39 of the hydraulic cylinder 38 is extended or shortened, the swing beam 31 is configured to swing around the pin 34 in the direction of arrow 43a or arrow 43b.

Next, balanced beam groups 50, 50 are arranged near one end 31a and the other end 31b of the swing beam 31, respectively.

FIG. 2A is a sectional view showing the vicinity of one end 31a of the swinging beam 31.
A boss 44 is fixed to the hole 44a of the boss 44.
A pin 45 is inserted into and extends in a cantilevered manner, and is equipped with a group of balance beams 50, which will be described later.

In addition, FIG. 2A shows the other end 31b of the swinging beam 31.
Although a part of the vicinity is shown in cross-section, a boss 46 is fixed to the swing beam 31, a pin 47 is inserted and fitted into a hole 46a of the boss, and the pin 47 is attached to one side. Equilibrium beam group 5, which will be described later, extends in a vertical position.
0 is equipped.

Although this balanced beam group 50 is completely equivalent to the configuration of a conventionally used balanced type pressure receiving line device, it will be described below using FIG. 3 just in case.

The first balanced beam 51 has two side plates 52, 52
are integrally fixed in parallel to each other by a boss 53, and the hole 53a of the boss 53 is a portion to be rotatably inserted into the pin 45.

Next, the second balanced beam 54 has two side plates 55,
55 are integrally fixed in parallel to each other by a boss 56, and a hole 56a of the boss 56 is a portion into which a pin 57 is to be rotatably inserted. Pressure receiving cable rings 60, 60 are rotatably attached to the inner sides sandwiched between the side plates 55, 55 and near both ends using pins 58, 58, respectively.

Using two sets of second balance beams 54 assembled in this way, the second balance beams 54 are placed in a region sandwiched between the side plates 52, 52 of the first balance beam 51 and near both ends. The beams 54, 54 are rotatably pivoted to the holes 56a, 56a of the bosses 56, 56 using pins 57, 57, respectively.

In this way, the pin 4 of the swing beam 31
5, a first balance beam 51 is rotatably attached to the first balance beam 51, and a pair of second balance beams 54, 54 are respectively rotatably attached near both ends of the first balance beam 51. , and further the two sets of second balanced beams 5
Two guiding rope wheels 60, 60, 60, 60 for guiding the refraction of the rope 61 are rotatably attached to the two guide wheels 4 and 54, and in this way, the balanced beam group 50
will be equipped.

In addition, the pin 47 of the swing beam 31 is also equipped with a group of balanced beams 50 in the same way as described above, and in this way, near both ends of the swing beam 31, the group of balanced beams 50, 50 is equipped.

Next, the hydraulic cylinder 38 is connected to a hydraulic unit 70 through a pipe 71, and pressure oil is supplied from the hydraulic unit 70. As the hydraulic unit 70, a known device including an electric motor, a hydraulic pump, and a constant pressure device and capable of constantly supplying pressure oil at a substantially constant force can be used.

In addition, although this embodiment is described in the case of a pressure cable device that bends the cable in a concave upward direction, a similar configuration can also be used in the case of a pressure cable device that bends the cable in a concave downward direction. Of course you can.

[Function] The function of this device having the above-mentioned configuration is described in the fourth section.
This will be explained next using Figures A and B.

FIG. 4A shows a case where the single swing type pressure receiving cable device 30 is installed on the support arms 36 and 42 of a support (not shown) located near the stop 80 on the foot of the cableway. The pin 34 side serving as a fulcrum is arranged on the side where the vertical positional fluctuation of the cable 61 is to be restricted, that is, in the direction of the stop 80, and on the side where the vertical positional fluctuation of the cable 61 is not restricted, that is, in the direction of the cableway track 81.
The hydraulic cylinder 38 side is arranged and used.

That is, the vicinity of one end 31a of the swing beam 31 is pivotally supported by a pin 34 via a bracket 35 on the support arm 36 in the fixed position. The support arm 42 also has a bracket 41 and a pin 4.
0, the vicinity of the other end 31b of the swing beam 31 is supported via the hydraulic cylinder 38 and the piston rod 39 by a pin 37, and the piston rod 3
It is made swingable in the stroke direction of 9.
The hydraulic cylinder 38 is connected by a pipe 71 to a hydraulic unit 70 disposed at a suitable fixed position, for example, on a column, and the operation of the hydraulic unit 70 supplies almost constant pressure oil to the hydraulic cylinder 38. or made expellable.

A pair of balanced beam groups 50 and 50 are connected near one end 31a and the other end 31b of the swing beam 31 by pins 45 and 47, respectively.
is pivotally mounted, and each of the final balanced beams of the balanced beam groups 50, 50 (in this case, the second balanced beam 54; however, it is omitted from FIGS. 4A and 4B to avoid cluttering the drawings). multiple pressure-receiving ropes 6
0,60... are pivotally mounted. The cables 61 are introduced into the plurality of pressure cable rings 60, 60...60 at an angle from the cableway direction 81, and each pressure cable ring 6
0, 60...60, the pressure cable is supported while being refracted one after another, and it turns almost horizontally to the berth 80.
Each of the components is sized and arranged so as to be guided therein.

In such a steady state, by bending the cable 61, among the loads directed upward due to cable tension, one end 31a of the swinging beam 31 is
The load on the side is mostly borne by the prop arm 36 via the pin 45, and the load on the other end 31b side is mostly borne by the prop arm 42 via the hydraulic cylinder 38. In a steady state, the load due to the bending of the cable remains constant without fluctuation, so it is in equilibrium with the pressure determined by the constant pressure device (not shown) of the hydraulic unit 70, and the hydraulic cylinder 38 supplies and discharges pressure oil. Therefore, the piston rod 38 does not slide up and down, and the swing beam 31 also does not swing and remains substantially constant.

In addition, each component of the balanced beam group 50, 50... works together so that the refraction angles or loads of the pressure receiving rope rings 60, 60...60 are equal to each other, and the balance is maintained. There is.

Next, FIG. 4A shows a transient state, for example,
The carrier 63, which has gripped the cable 61, moves in the cableway direction 8.
The state when approaching from 1 is shown.

When the carrier 63 approaches as shown, the weight of the carrier causes the cable 61 to bend or move downward from its original position in the steady state (the position of the cable 61 indicated by the chain line), as indicated by the solid line. Position of cable 6
It descends to 1'. Along with this, the upward load due to the bending of the cable is reduced, so pressure oil is supplied to the hydraulic cylinder 38 by the constant pressure device (not shown) of the hydraulic unit 70, and the piston rod 39
extends downward, so that the swinging beam 31 moves from the original position in the steady state (swinging beam 31 shown in chain lines) to the position 3 of the swinging beam 31 shown in solid lines.
1', the cable 61 (position 6) is rotated about the pin 34 in the direction of arrow 64a.
1') is maintained until the load due to bending and the pressure set by the constant pressure device of the hydraulic unit 70 are balanced. At this time, it goes without saying that the balance beam groups 50, 50 work together to perform a balancing operation so that the refraction angles and loads of the respective pressure-receiving rope rings 60, 60, . . . , 60 are always equal.

What should be noted here is that even in this transient state, the pressure-receiving cable rings 60, 60, . , does not cause local refraction etc. in the cable 61, and on the other hand, the swinging beam 3
Pressure receiving cable rings 60, 60 near one end side 31a of 1.
causes almost no up-and-down movement, and therefore the height H of the cable 61 introduced into the station 80 by these movements will hardly change from that in the steady state described above, and even if it does occur, Also one end 31a
This amount is small and stable, and does not exceed the vertical displacement of the cable 61 caused by the self-balancing operation of the side balanced beam group 50.

Next, when the carrier 63' similarly enters the vicinity of the position shown by the dotted line in FIG. The cable height H of the bus stop 80 does not change.

Also, the cableway direction 8 shown in Figure 4A
Regardless of the type of rope gripping device 62 (abbreviated with a black circle in the figure) of the carrier 63 entering from 1, it can be schematically regarded as a kind of protrusion attached to the rope 61. Particularly in the case of high-speed operation, this protrusion can be viewed as a model in which it collides with and passes through the pressure receiving cable rings 60, 60...60 one after another, and this also normally differs from the general case. This causes complex rocking vibrations in the balanced pressure rope device, but in the device of the present invention, the rocking in such cases only occurs on the other end 31b side, and has no large effect on the one end 31a side. Therefore, the influence on the height H of the cables introduced into the parking area 80 is small.

(C) Effects of the Invention The single swing type pressure receiving rope device of the present invention produces the following effects, as partially described in the section of the above-mentioned function.

When a conventional balanced type pressure receiving cable device is used as a pressure receiving cable device on a column attached to a cableway stop installed near the entrance/exit of a cableway stop, especially when a multi-wheel device is used on a steep slope route and high-speed operation is desired. In this case, it was not possible to avoid vertical displacement of the height of the cable introduced into the station due to the movement of the carrier.

However, if this one-way balanced type pressure line device is used, (a) transient oscillations of the pressure line device caused by the approach of a carrier, etc. are allowed only on one side of the device, and the other Since the cable height can be limited, the height of the cables introduced into the parking lot etc. can be kept almost constant at all times.

(a) Due to the constant pressure device (not shown) of the hydraulic unit, the pressure receiving cable ring always follows the cable at a substantially constant pressure.

(c) Moreover, the balanced beam groups arranged near both ends of the swinging beam have a self-balancing function in which all the pressure-receiving cable rings are equally loaded by working together, causing local bending of the cables, etc. In this respect, it has the same cable protection function as the conventional balanced pressure receiving cable device.

(d) In the description of this specification, the case is mainly shown in which the present invention is used as a pressure line device, but it goes without saying that it can be implemented with almost the same configuration in the case of a cable receiving device.

It has the following effects, and is particularly suitable for use in multi-wheel pressure cable devices used on steep slope railways and when operating at high speeds. It greatly contributes to the stable operation of mechanical equipment.
