Description

[Detailed Description of the Invention] Industrial Application Field The present invention is directed to attaching movable metal wheels used for cable extension to a suspension line, and to arrange the movable metal wheels at regular intervals on the suspension line. This invention relates to the structure of a connecting rope for a mobile money wheel that connects to cars at regular intervals.

Conventional technology As shown in Fig. 3, the conventionally known connecting rope for moving gold wheels (Utility Model Registration No. 1328700) does not include a transmission line, and the transmission line is inserted between the cable supports in the cable extension. If this is required, a transmission line must be installed separately between the cable supports and removed after the cable has been extended. As a method to solve this problem, there is a method (Japanese Patent Application No. 59-257081) of using a wire extension control cable instead of the connecting rope for the moving gold wheel.

This will be explained based on FIGS. 4, 5, 6, and 7.

In the figure, 1 is a wire extension control cable, 2 is a moving metal wheel, 3 is a cable clamp, 4 is a ring, and 5
1 is a connector, 6 is a telephone pole, 7 is a hanging wire, 8 is a hook for a moving metal wheel, 9 is an end of a cable for controlling the extension (hereinafter referred to as a cable end), 10 is a pulling rope, 11
12 is a tightening tube, 13 is a ring, and 14' is a rope.

In this method, as shown in FIG. 4, rings 4 are fixed to the cable 1 at intervals corresponding to the required spacing of the movable metal wheels 2, and the wire extension control cable 1 with connectors 5 provided at both ends is shown in FIG. As shown in FIG. 6, the wire extension control cable 1 is connected to the moving metal wheel 2 on the hanging wire 7 using the ring 4, and the end of the wire extension control cable 1 is fixed to the pulling rope 10 inserted through the moving metal wheel 2 as shown in FIG. Pull rope 1
When pulled together with 0, the wire extension control cable 1 and the pulling rope 10 are simultaneously extended, and the movable metal wheels 2, 2...
... is placed at a predetermined position. When the next utility pole 6 is reached, the end 9 of the next extension control cable 1 is connected with the connectors 5, 5, and the pulling rope 10 is connected to the next moving wire wheel 2, 2... Pass through it and pull it together with the end end 9 of the next control cable 1 for extension.

The above work is carried out throughout the cable extension route. If you use this method, the moving gold wheel 2, 2...
... can be deployed on the hanging wire 7 and the transmission line can be installed at the same time, reducing labor.

Problems that the invention aims to solve: However, when the distance between the utility poles 6, 6... is long, the number of movable gold wheels 2 placed at regular intervals on the suspension line increases, and the number of movable gold wheels 2 connected to the mobile gold wheels 2 increases It was necessary to pull the wire extension control cable 1 with a large tension. For this reason, the wire extension control cable 1 needs to have a tensile strength structure, which increases the weight and outer diameter of the wire extension control cable 1 and reduces its flexibility, resulting in a moving metal wheel as shown in FIG. There was a drawback that the wire extension control cable 1 was bent greatly at the connecting part with the cable 2 and was not bent sufficiently, and the wire extension control cable 1 was twisted when the moving metal wheel 2 was deployed. Additionally, an increase in weight resulted in an increase in the required tension, a cascading drawback.

Means for Solving the Problems The present invention connects a plurality of ropes with a ring with a length corresponding to the required spacing between the movable gold wheels arranged on a suspension line, and attaches each rope to both ends of the connected ropes. In the moving metal wheel connecting rope with a hook attached, insert the transmission line from the point where the hook is connected at one end of the moving metal wheel connecting rope, pull out the transmission line from the other end where the hook is attached, and connect the transmission line. A connector is connected to the insertion end and the pull-out end of the rope, and a transmission line is constructed by bypassing the connecting ring so that it is pulled out from the connecting end of the intermediate connecting ring and inserted into the connecting start end, and is connected to the rope. This is made by tightening the ropes at the insertion and extraction ends of the transmission line with a tube.

Function The present invention has the same flexibility as a conventional rope in the ring part by exposing and detouring the transmission line in the ring part and continuously inserting the transmission line into the connecting rope for the moving metal wheel. This results in an effect that allows the rope to share the functions of sheathing and tensile strength of the cable for holding and controlling cable extension.

Embodiment Fig. 1 is a plan view of a connecting rope with a transmission line for a moving metal wheel of the present invention (hereinafter referred to as the connecting rope),
The diagram shows the rope with transmission line in Figure 1, (A) is an enlarged view,
Figure (b) shows a cross-sectional view taken along the -' line in figure (a).

In the figure, the same symbols as in FIG. 3 indicate the same parts. 15 is a connector, 16 is a transmission line, and 17 is a twisted strand of rope.

The structure of the connecting rope of the present invention is such that ropes 14', 14'... of a length corresponding to the required spacing between the movable metal wheels 2, 2... disposed on the hanging line 7 are connected to the ring 13,
13... and hooks 11, 11 are attached to both ends, the transmission line 16 is inserted into the rope 14' from the side of the rope 14' where the hook 11 is attached on one side, and the opposite ring 13 is connected. The transmission line 16 is taken out from the side of the rope 14' at the attachment part of the rope 14', and the ring 13 part is bypassed.
Connect the transmission line to rope 1 from the side of the next rope 14'.
4' and taking it out from the side of the rope 14' where the opposing ring 13 is attached is repeated sequentially, and the transmission line 16 is continuously inserted into all the ropes 14', 14'... The rope 14 is tightened by a tube 12 which tightens the attachment portions of the ring 13 and the hook 11. Note that the rope 14' is a hollow braid rope.
rope) structure, the rope 14' is composed of twisted strands, and the twisted strands 17
Since there is mutual play, applying a compressive force in the longitudinal direction to a part of the rope 14' creates a gap between the twisted strands 17, and the transmission line can be expanded to an arbitrary inner diameter after the rope 14' is manufactured. 16 can be easily inserted.

Because of this structure, the connection between the connecting ropes of the present invention is made by hook 11 and hook 1.
1 and the connector 15 and the connector 15, and when tension is applied, the rope 1 of the conventional configuration
4' and the transmission line 16 inserted into the rope 14' will have the same elongation, but most of the tension will be shared by the rope 14' and the transmission line 16 will not break.
Furthermore, since the rope 14' functions as the outer sheath of the transmission line 16, the outer sheath of the transmission line 16 only needs to have an insulating function and does not need to be wear resistant. ring 1
3, the transmission line 16 is exposed from the transmission line rope 14 and the tightening tube 12 prevents the transmission line 16 from moving within the transmission line rope 14. By retaining the slack in the
Rope 1 with transmission line in the periphery of ring 13
The flexibility of the wire 4 is not hindered, and when the movable wire wheels 2, 2... on the hanging wire 7 are connected using the rings 13, 13..., the conventional movable wire consisting only of ropes as shown in FIG. The situation is the same as in the case of a car connecting rope. Therefore, the outer sheath of the transmission line 16 can be made thinner, and the weight and outer diameter of the transmission line 16 as a whole can be reduced. In addition, the connecting rope 1 containing the transmission line 16
4 can be made equivalent to the connecting rope 14' without the transmission line 16. In addition, moving gold wheel 2,
2. There is no kink when the suspension wire 7 of . . . is expanded.

Effects of the invention The present invention maintains flexibility in the ring part by continuously inserting the transmission line into the connecting rope for the moving metal wheel while exposing and detouring the transmission line in the ring part as described above. By assigning the sheathing and tensile strength functions necessary for the transmission line to the rope, it is possible to add a transmission function without impairing the function of the conventional connecting rope for moving gold wheels. As a result, the outer diameter and weight increase, and the required tensile strength increases, but the increased tensile strength can be shared by the rope, which suppresses the disadvantage of increasing the required tensile strength of the transmission line. be able to.
