Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double single-line cableway commonly called “DLM (double loop mono cable)”.
[0002]
[Prior art]
FIG. 5 is an explanatory perspective view showing a conventional single-wire cableway.
This double single-track cableway forms a reciprocating path by winding a single support cable 4 between a driving pulley 3 and a tension pulley 1 in a double loop shape.
[0003]
The driving pulley 2 has an upper pulley 31 and a lower pulley 32 attached to a driving shaft in the vertical direction. On the other hand, the tension pulley 1 includes a third pulley 13 disposed at the center position, and a first pulley 11 and a second pulley 12 disposed on the left and right sides of the pulley 13 and above the center pulley 13. Become.
[0004]
One support rope 4 goes around the upper pulley 31 of the driving pulley 3 and departs to the tension pulley side, and goes around the first pulley 11 and the second pulley 12 to drive the driving pulley (lower pulley 32). Returning to FIG. 3, the outer ropes 41 and 42 constitute the outer loop 4 </ b> A of the reciprocating path.
[0005]
The outer loop 4A (rope 42) circulates around the lower pulley 32, circulates around the third pulley 13 and returns to the driving pulley (upper pulley 31) 3. The loop 4B is configured.
[0006]
Furthermore, the inner loop 4B (rope 44) goes around the upper pulley 31 and is continuous with the outer loop 4A (rope 41), so that an endless loop is set. In other words, four of the outer ropes 41 and 42 and the inner ropes 43 and 44 of the reciprocating path are wound in an endless loop shape.
[0007]
As shown in FIG. 4, the transporter X grips two adjacent ropes (adjacent inner line 44 and outer line 42) with the two gripping machines X1 and X1 at the left and right ends of the ceiling, and moves the rope. Move with.
[0008]
In the normal state, each of the two transporters X and X is located at the foothill side stop (Platform Y) V and the other is located at the summit side stop (Platform Y) W. The two transporters X and X are transferred to the opposite stops V and W, respectively.
[0009]
[Problems to be solved by the invention]
As shown in FIG. 4, the conventional tension pulley 1 includes three pulleys (a first pulley 11, a second pulley 12, and a third pulley 13) arranged side by side. It is installed on a carriage 17a provided on 24a.
[0010]
The three pulleys 11, 12, and 13 are integrated by a connecting arm 22a of a tension driving device, and the tension state is adjusted by the carriage 17a being moved by a hydraulic cylinder 21a directly connected to the connecting arm.
[0011]
That is, for example, when slack occurs in the outer loop (ropes 41, 42) 4A, when the hydraulic cylinder 21a is driven and the cylinder rod 23a is pulled, the carriage 17a moves, that is, the three pulleys 11, 12, 13 are moved. Retreat as one.
[0012]
Therefore, the outer loop 4A is adjusted to an appropriate tension state, while the inner loop 4B that is in a normal tension state is in an overstressed state. As a result, in the system in which the three tension pulleys are displaced together, there is a disadvantage that it is difficult to adjust the tension side support ropes (ropes 41, 42, 43, 44) 4 to the same tension. There was a drawback that driving safety was not sufficient.
[0013]
The present invention solves the above-mentioned problems, and can apply a uniform tension to each of the ropes of the inner loop and the outer loop constituting the reciprocating path and always maintain them with a simple system. It aims at providing the double type single cable way which can realize safe driving.
[0014]
[Means for Solving the Problems]
In order to achieve this object, the double single track of the present invention has the following configuration.
A compound single-wire cableway is a compound single-wire cableway in which a single support cable is wound in a double loop between a driving pulley and a tension pulley, and the tension pulley is directly connected to a tension driving device. The first pulley and the second pulley, which are arranged on the first carriage and circulate the outer loop of the reciprocating path between the first pulley and the first pulley, and are arranged on the second carriage and reciprocate between the first pulley and the first pulley. A third pulley that circulates the inner loop of the road, and a second carriage that is arranged coaxially with the third pulley and circulates the outer loop between the first pulley and the second pulley. It is characterized by comprising a pulley.
[0015]
In the double single wire cable having such a configuration, the third pulley that circulates the inner loop is installed in the second carriage and is not directly connected to the tension driving device. On the other hand, the first pulley and the second pulley that go around the outer loop are installed in the first carriage and directly connected to the tension driving device. Further, a second carriage guiding pulley that is interposed between the first pulley and the second pulley and circulates around the outer loop is disposed coaxially with the third pulley, that is, on the second carriage.
[0016]
As a result, if the outer loop is loosened for some reason, the inner loop is also loosened slightly. Here, the tension driving device (hydraulic cylinder) pulls the first carriage until the normal tension is reached. At this time, the second carriage is subjected to half the tension applied to the first carriage by the second carriage guiding pulley.
[0017]
This makes it possible to apply equal tension to the four ropes on the tension side without applying excessive tension to the inner loop (two inner ropes) as well as the outer loop (two outer ropes). it can.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the double single wire cableway according to the present invention will be described with reference to the drawings.
FIG. 2 is an explanatory plan view showing a compound single wire cableway according to the embodiment.
In this embodiment, a so-called “DLM (double loop mono cable)” type cableway is illustrated.
[0019]
This cableway is a cableway track in which a single support cable 4 is wound in a double loop between a driving pulley 3 and a tension pulley 1, and the tension pulley 1 is between the driving pulley 3 The third pulley 13 that circulates the inner loop 4B of the reciprocating path between the first pulley 11 and the second pulley 12 that circulates the outer loop 4A of the reciprocating path and the driving pulley 3 and the third pulley 13 The pulley 13 and the second carriage guiding pulley 14 arranged on the same axis are configured.
[0020]
A feature of the present invention is that the first pulley 11 and the second pulley 12 are provided in the first carriage 15 directly connected to the tension driving device 2, and the third pulley 13 is the second carriage 16. And a second carriage guiding pulley 14 is provided coaxially with the third pulley 13.
[0021]
As shown in FIG. 2, the driving pulley 3 has an upper pulley 31 and a lower pulley 32 fixed to each other in the vertical direction with respect to the driving shaft (rotating shaft). A driving device is connected to the driving shaft (not shown).
[0022]
The tension side pulley (the first pulley 11, the second pulley 12, the third pulley 13, and the second carriage guiding pulley 14) 1 is a stop V and is disposed behind the landing Y. .
[0023]
That is, as shown in FIG. 1, the second carriage 16 is provided in the upper surface of the tension board 24, forward (on the landing side), and the first carriage 15 is provided behind the second carriage 16. The second carriage 16 has a third pulley 13 attached below the rotation shaft 16a and a second carriage guiding pulley 14 attached above.
[0024]
In addition, the first pulley 11 and the second pulley are formed at both ends of the first carriage 15, that is, in a virtual triangular shape having the second carriage guiding pulley (third pulley 13) 14 as a vertex. A pulley 12 is attached.
[0025]
The tension drive device 2 includes a hydraulic cylinder 21, a rod 23 of the cylinder 21, and a planar triangular connecting arm 22 directly connected to the tip of the rod 23.
The first pulley 11 and the second pulley 12 are integrally installed on the flat first cart 15 via the connecting arm 22.
[0026]
As shown in FIG. 2, the single support rope 4 circulates around the upper pulley 31 of the driving pulley 3 and departs to the tension pulley 1 side, and circulates around the first pulley 11 to form a second U-turn. The second pulley 12 is turned after the carriage guide pulley 14 is turned.
[0027]
That is, between the first pulley 11 and the second pulley 12, the tension force applied to the first carriage 15 is reduced by the fourth loop 15 </ b> A being interposed in the outer loop 4 </ b> A in the opposite direction. It is intended to act on the second carriage 16 via the pulley 14 and the third pulley 13.
[0028]
Furthermore, it goes around the second pulley 12 and returns to the driving pulley 3 so that the two ropes 41 and 42 constitute the outer loop 4A. The end (outer rope 42) of the outer loop 4A goes around the lower pulley 32 on the driving side, starts again toward the tensioning pulley, and returns to the driving pulley 3 via the third pulley 13 to The inner ropes 43 and 44 of the book constitute the inner loop 4B.
[0029]
The end of the inner loop 4B (inner rope 44) goes around the upper pulley 31, that is, continues to the start end (outer rope 41) of the outer loop 4A, so that one supporting rope 4 is installed in an endless loop shape. Is done.
[0030]
In the double single-wire cableway having such a configuration, the four overhead wires of the outer loop 4A (outer ropes 41 and 42) and the inner loop 4B (inner ropes 43 and 44) are originally set to have the same tension. Yes.
[0031]
However, the tension state of either the outer ropes 41, 42 or the inner ropes 43, 44 may be loosened for some reason during operation.
For example, when the support rope of the outer rope 41 is loosened for some reason, the outer rope 42 is also loosened via the first pulley 11 and the second carriage guiding pulley 14. Furthermore, the inner ropes 43 and 44 are also slightly loosened via the second carriage guiding pulley 14 and the third pulley 13.
[0032]
When correcting this, the tension driving device 2 (hydraulic cylinder 21) is driven, and the first carriage 15 on which the first pulley 11 and the second pulley 12 are placed is set to a normal tension (a preset tension). Pull until).
[0033]
As a result, appropriate tension is applied to the outer ropes (outer loop 4A) 41, 42 in a relaxed state. At the same time, the second carriage 16 is moved by the outer loop guiding portion 41 a and the second carriage guiding pulley 14. That is, half the tension applied to the first carriage 15 is applied to the second carriage 16 (see FIG. 3).
[0034]
As a result, an unreasonable (not excessive) tension acts on the inner ropes (inner loop 4B) 43, 44, and as a result, an equal tension can be applied to the four ropes 41, 42, 43, 44 on the tension side. .
[0035]
On the other hand, when the tension of the support rope of the outer rope 41 increases for some reason, that is, when an excessive tension exceeding the preset tension acts, the tension of the outer rope 42 also increases, and the second The tensions of the inner ropes 43 and 44 also slightly increase through the carriage guiding pulley 14 and the third pulley 13.
[0036]
The tension driving device 2 has an appropriate constant tension value set in advance. Accordingly, when excessive tension acts on the outer rope 41, the cylinder rod 23 automatically extends until the hydraulic cylinder 21 reaches an appropriate constant tension value. As a result, the four ropes 41, 42, 43, and 44 are always maintained at substantially the same tension.
[0037]
【The invention's effect】
According to the present invention, as described above, the first pulley and the second pulley that are the single-line cableway that circulates the outer loop are installed in the first carriage directly connected to the tension driving device, and the inner loop is circulated. The third pulley is installed on the second carriage, and the second carriage guiding pulley is arranged coaxially with the third pulley to circulate the outer loop between the first pulley and the second pulley. Therefore, it is possible to always apply substantially uniform tension to the four ropes on the tension side.
[0038]
Further, the second carriage on which the third pulley rides is separated from the first pulley and the first carriage on which the second pulley rides, and the second carriage is a second carriage guiding pulley, Because it moves forwards and backwards, it does not apply excessive tension to any of the inner and outer loops that make up the reciprocating path of the endless loop, and it is equal to each of the four inner and outer ropes with a simple operation. Therefore, it is possible to adjust and give a proper tension, and to realize the effect of achieving the object of the invention, such as the safer transfer of the transporter.
