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. 4 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 3 in a double loop between the driving pulley 2 and the tension pulley 1.
[0003]
The driving pulley 2 has two rope grooves 25 and 26 recessed in the vertical direction on the peripheral surface of a single pulley. On the other hand, the tension pulley 1 includes a first pulley 15 disposed at a central position, and a second pulley 16 and a third pulley 17 disposed on the left and right sides of the pulley 15 and above the central pulley 15. Become.
[0004]
One support rope 3 goes around the rope groove 25 on the upper side of the driving pulley 2 and starts to the tension pulley side, goes around the first pulley 15 and returns to the driving pulley 2, and the inner ropes 34 and 33 An inner loop 3A of the reciprocating path is configured.
[0005]
The inner loop 3A (rope 33) goes around the lower rope groove 26 and returns to the driving pulley 2 via the second pulley 16 and the third pulley 17, and the outer ropes 32 and 31 The outer loop 3B is configured.
[0006]
Further, the outer loop 3B (rope 31) circulates in the upper rope groove 25 and is continuous with the inner loop 3A (rope 34), so that an endless loop is set. That is, four of the outer ropes 31 and 32 and the inner ropes 33 and 34 of the reciprocating path are wound in an endless loop shape.
[0007]
The transporters X and Y grip two adjacent ropes (adjacent inner and outer lines) with the width of the transporter and move with the movement of the ropes.
The two transporters X and Y are normally located at the foot of the hillside and the other at the summit of the hillside, and the two transporters X and Y are driven by the driving pulley 2 respectively. Transfer to the opposite stop.
[0008]
[Problems to be solved by the invention]
As shown in FIG. 4, the conventional tension pulley 2 has three pulleys (a first pulley 15, a second pulley 16, and a third pulley 17) arranged side by side as a single unit with a connecting plate 18. A hydraulic drive device 19 </ b> A is connected to the connecting plate 18.
[0009]
In other words, the tension pulley in an integrated state is connected to a single hydraulic cylinder 19 so that the three pulleys 15, 16, and 17 move together.
[0010]
For this reason, when slack occurs in the inner loop (inner ropes 33, 34) 3A, when the hydraulic cylinder 19 is operated, the three tension pulleys 15, 16, 17 are moved backward together.
[0011]
As a result, the inner loop 3A is adjusted to an appropriate tension state, while the outer loop 3B that is in an appropriate tension state is in an overstressed state. Therefore, the method of displacing the three tension pulleys integrally has the disadvantage that it is difficult to apply equal tension to the four inner and outer ropes, and there is a disadvantage that the safety of the transporter is not sufficient. It was.
[0012]
This invention eliminates the above-mentioned problems, can always apply equal tension to each of the inner loop and outer loop ropes constituting the reciprocating path, and can realize further safe traveling of the transporter. The aim is to provide a single cableway.
[0013]
[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. A first pulley for circling the loop and a second pulley for circling the outer loop of the reciprocating path between the driving pulley and the first pulley and the second pulley are connected to the driving pulley by a tension driving device. It is characterized by the fact that each distance can be individually displaced.
[0014]
In the double single wire cable having such a configuration, the first pulley that circulates the inner loop and the second pulley that circulates the outer loop each advance and retreat individually.
[0015]
That is, when a predetermined tension state is applied to the entire double winding loop (circulation loop), the distance between the first pulley and the second pulley is reduced. Conversely, when it is necessary to add a predetermined relaxed state, it can be adjusted by increasing the distance between the first pulley and the second pulley.
[0016]
Specifically, for example, when the tension of the outer loop (two outer ropes constituting the outer loop) becomes loose, the second pulley is pulled by the hydraulic cylinder. That is, the second pulley is moved and displaced to the tension driving device side (the driving pulley side). As a result, the distance between the second pulley and the guide wheel disposed at a position outside the second pulley is increased, and the looseness of the rope is absorbed.
[0017]
On the contrary, when the expansion of the inner loop (two ropes inside the forward / return path) becomes loose, pull the first pulley with the hydraulic cylinder. That is, the first pulley is moved and displaced to the tension drive device side (the side opposite to the driving pulley). As a result, the distance between the first pulley and the driving pulley is increased, and the looseness of the rope is absorbed accordingly.
[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. 1 is an explanatory plan view showing a double 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 3 is wound in a double loop between a driving pulley 2 and a tension pulley 1, and the tension pulley 1 is inside the reciprocating path with the driving pulley 2. The first pulley 11 that circulates the loop 3A and the second pulley 12 that circulates the outer loop 3B of the reciprocating path between the driving pulley 2 and the pulley 3 are configured.
[0020]
The first pulley 11 and the second pulley 12 are adjusted to have equal tension on the inner loop 3A and the outer loop 3B by individually adjusting the distance from the driving pulley 2 by a tension driving device 4 described later. It is comprised so that it may act.
[0021]
As shown in FIG. 3, the driving pulley 2 has an upper pulley 21 and a lower pulley 22 fixed to a driving shaft (rotating shaft) 23 in the vertical direction at a predetermined interval. The driving shaft 23 is connected to the driving device 23A.
[0022]
As shown in FIG. 1, the tension pulley 1 includes a first pulley 11 that circulates the inner loop 3A, and a second pulley 12 that circulates the outer loop 3B.
The first pulley 11 is disposed closer to the drive pulley 2 than the second pulley 12, and a tension driving device 4 is disposed between the first pulley 11 and the second pulley.
[0023]
In addition, as shown in FIG. 1, guide wheels 53 and 54 are arranged at positions on the left and right sides of the second pulley 12 opposite to the position of the first pulley 11 (position farthest from the driving pulley 2). At the same time, the guide wheels 52 and 51 are arranged on the driving pulley 2 side in the same manner to constitute the track of the outer loop 3B.
[0024]
As shown in FIG. 2, the tension drive device 4 is a hydraulic drive device, and includes a first hydraulic cylinder 41 connected to the first pulley 11 on one side of the apparatus main body 4 </ b> A, and a second on the other side. And a second hydraulic cylinder 42 connected to the pulley 12.
[0025]
In the embodiment, support frame bodies 11 a and 12 a are attached to the first pulley 11 and the second pulley 12, respectively. The rotating shaft of each pulley 11 (12) is supported by the support frame 11a (12a). The support frame 11a (12a) is set to be slidable with respect to the fixed column 11b (12b).
[0026]
Further, the tip (rod head) of the first hydraulic cylinder 41 is fixed to the end of the support frame 11a, and the tip (rod head) of the second hydraulic cylinder 42 is fixed to the end of the support frame 12a. The first pulley 11 and the second pulley 12 advance and retract separately.
[0027]
As shown in FIG. 1, one supporting rope 3 goes around the upper pulley 21 of the driving pulley 2, starts to the tension pulley 1 side, goes around the first pulley 11, and returns to the driving pulley 2. Thus, the two inner ropes 34 and 33 constitute the inner loop 3A.
[0028]
At this time, the terminal end (inner rope 33) of the inner loop 3A goes around the lower pulley 22 of the driving pulley 2 and starts again toward the tension pulley (see FIG. 3). In other words, the outer rope 32 half-circulates the guide pulley 53 on the tension pulley side via the guide wheel 51, then makes a half turn on the second pulley 12, and further turns back around the guide wheel 54, and passes through the guide wheel 52. By returning to the driving pulley 2, the two outer ropes 32 and 31 constitute the outer loop 3B.
[0029]
Then, the end of the outer loop 3B (outer rope 31) goes around the upper pulley 21, that is, continues to the starting end (inner rope 34) of the inner loop 3A, so that one support rope 3 is installed in an endless loop shape. Is done.
[0030]
In the double single wire cable having such a configuration, the advancement / retraction of the first pulley 11 that circulates the inner loop 3A and the second pulley 12 that circulates the outer loop 3B are individually adjusted.
[0031]
That is, the distance between the first pulley 11 and the second pulley 12 is reduced when a predetermined tension state is applied to the entire double winding loop (circulation loop). Conversely, when it is necessary to add a predetermined relaxed state, the entire tension can be appropriately adjusted by increasing the distance between the first pulley 11 and the second pulley 12.
[0032]
Specifically, as shown in FIG. 2, for example, if the tension of the inner loop (inner rope 33 or inner rope 34) 3A is loosened, the hydraulic cylinder 41 is operated. That is, the support frame (base 11b) 11a is pulled toward the second pulley 12 and moved by a predetermined distance.
[0033]
Thereby, when the distance between the first pulley 11 and the driving pulley (upper / lower pulleys 21 and 22) 2 is increased, the loose state is absorbed and the tension can be adjusted to an appropriate tension.
[0034]
On the contrary, when the tension of the outer loop (outer line 31 or outer line 32) becomes loose, the hydraulic cylinder 42 is operated. That is, the support frame (pedestal 12b) 12a is pulled toward the first pulley 11 and moved by a predetermined distance.
[0035]
Thereby, when the distance between the guide wheels 53 and 54 and the second pulley is increased, the loose state is absorbed, and an appropriate tension can be applied.
Thus, the first pulley 11 and the second pulley 12 individually move forward and backward individually, or finely adjust each other's position cooperatively to form a double-wound endless loop reciprocating path. Appropriate tension can be applied to the four inner and outer ropes 31, 32, 33, and 34 according to the situation.
[0036]
【The invention's effect】
In the present invention, as described above, an endless loop line cableway comprising an inner loop and an outer loop, in which a single support rope is wound in a double loop between a driving pulley and a tension pulley. A configuration in which the position of the first pulley that circulates the inner loop with the driving pulley and the second pulley that circulates the outer loop with the driving pulley can be individually adjusted by the tension driving device. Therefore, the tension state of the inner loop and the outer loop can be adjusted individually.
[0037]
The inner and outer loops that make up the endless loop reciprocating path are not allowed to apply an appropriate tension according to the situation, but each of the four inner and outer ropes is adjusted with equal tension. It has the excellent effect of achieving the object of the invention, such as being able to transport the transporter more safely.
