【考案の詳細な説明】
(産業上の利用分野)
この考案は同軸ケーブルの多条同時一括延線等
において、多条の各同軸ケーブル端を接続して、
メツセンジヤーワイヤーに沿つて引つ張る多条用
先導ローラ付ヨークに関するものである。[Detailed explanation of the invention] (Industrial application field) This invention connects the ends of each coaxial cable in simultaneous multi-strip simultaneous running of coaxial cables, etc.
This invention relates to a yoke with a multi-strand leading roller that is pulled along a messenger wire.
(従来の技術)
従来CATV用等の同軸ケーブルは作業者が手
作業により各ケーブル毎にいちいち延線してい
る。(Prior Art) Conventionally, coaxial cables for CATV and the like are manually extended one by one by a worker.
しかしながら昨今の通信網の多様化に伴い同軸
ケーブルの布設需要が増大し、従来方法のような
専ら熟練作業者の手作業による各ケーブル毎の延
線では作業能率が悪い。 However, with the recent diversification of communication networks, the demand for laying coaxial cables has increased, and the conventional method of manually extending each cable by skilled workers is inefficient.
一方架空配電線の延線では多条一括同時延線工
法を行つており、この工法においてヨークを使用
している。 On the other hand, for the extension of overhead distribution lines, a multi-strip simultaneous extension method is used, and a yoke is used in this method.
(考案が解決しようとする問題点)
しかしながらこの架空配電線の延線に使用する
ヨークを同軸ケーブルの多条一括同時延線工法で
直ちに採用できるものではない。(Problems to be Solved by the Invention) However, the yoke used for extending this overhead power distribution line cannot be immediately adopted in the method of simultaneously extending multiple strips of coaxial cable.
同軸ケーブルはアルミパイプを用いているた
め、小さな力が加わつても曲り易く、またいつた
ん曲ると元に戻らない。従つてくせがつき易く、
多条の同軸ケーブルを同時に延線する際これらが
曲つたり、他のケーブルとからまつたりし易く、
それ故多条の各同軸ケーブルを所定位置に並べて
相互に分離しつつ延線しなければならない。また
同軸ケーブルは上記の構造の故高張力で延線でき
ず、従来の架空配電線用のヨークでは大きく垂れ
下がり、下方の回線等に引つ掛かつたりして延線
不可能となる。この様に多条同軸ケーブル同時一
括延線に適した多条用のヨークがないのが現状で
ある。 Because coaxial cables use aluminum pipes, they bend easily even when a small force is applied to them, and once bent, they do not return to their original shape. It is easy to become addicted to it,
When running multiple coaxial cables at the same time, they tend to bend or become entangled with other cables.
Therefore, multiple coaxial cables must be lined up at predetermined positions and separated from each other while being stretched. Furthermore, because of the above-mentioned structure, coaxial cables cannot be stretched under high tension, and with conventional yokes for overhead power distribution lines, they sag significantly and get caught on lines below, making it impossible to run them. At present, there is no multi-strand yoke suitable for simultaneously running multi-strand coaxial cables.
(問題点を解決するための手段)
そこでこの考案はこの様な多条の同軸ケーブル
を同時一括で延線する工法等において、多条の同
軸ケーブルの中央のケーブルがメツセンジヤーワ
イヤーの真下に常に位置し、かつ不必要に垂れ下
がらないヨークを提供するものである。(Means for solving the problem) Therefore, this idea was developed in such a method of simultaneously extending multiple coaxial cables at once, so that the center cable of the multiple coaxial cables is directly under the messenger wire. To provide a yoke that is always positioned and does not sag unnecessarily.

A support is erected on the upper surface, one end of the shaft of a suspension line wheel is supported on one side of the support, and this suspension line wheel is installed at a position corresponding to the center chain of the above-mentioned large number of chains. An opening/closing door is provided between the other end of the shaft and the plate-like main body, and a towing locking portion is provided on the edge opposite to the attachment edge to the chain.

れ、延線可能となる。(Function) Each grip provided at the rear end of a large number of coaxial cables is locked to each hook at the rear end of each of the chains.
Since the hook and chain are rotatably connected, even if the coaxial cable is twisted, it can be untwisted. Further, a twist return device is rotatably locked to the towing locking portion, and the end of the extended rope is locked to the twist return device. Also, open the door for the hanging line wheel, place the hanging line wheel on the messenger wire stretched between the utility poles, and close the door. This allows the yoke to be suspended from the messenger wire, making it possible to extend the wire.

ワイヤー24の真下に位置する。 In the case of this embodiment, a grip 21 is attached to one end of the coaxial cable 20, each of the hooks 3a is engaged with the loop portion of this grip 21, and in this way, a large number of coaxial cables 20 are engaged with this yoke. . Further, a return device 22 is locked by the above-mentioned pulling hole 11, and one end of the wire rope 23 is fixed to the return device 22 by twisting. Then, as shown in FIG. 3, loosen the wing nut 10 and raise the opening/closing door 7 along the elongated hole 8, insert the messenger wire 24 under the hanging wire wheel 6, and move the hanging wire wheel 6 to the messenger wire 24. Place it on top. Thereafter, the opening/closing door 7 is lowered, the lower end of the opening/closing door 7 is brought into contact with the upper surface of the plate-like main body 1, and the wing nut 10 is tightened to fix the opening/closing door 7. When the wire extension rope 23 is pulled, the suspension wheel 6 becomes a leading roller, and a large number of coaxial cables 20 are extended along the messenger wire 24. At that time, the tension of each of the many coaxial cables 20 is different, so the yoke is shifted, but as mentioned above, the messenger wire 24 passes through the inside surrounded by the support plate 4, the wire wheel 6, and the opening/closing door 7, so it derails. It is always located directly below the messenger wire 24.

This embodiment has almost the same structure as the above embodiment, but vertically elongated auxiliary rollers 25 are provided at both ends of the support plate 4 and the opening/closing door 7, respectively. In this embodiment, due to the difference in the tension of each of the many coaxial cables 20, this yoke is displaced, and no matter what angle the messenger wire 24 enters the hanging wire wheel, the messenger wire 24 can be moved to the support plate 4 or There is no damage caused by the opening/closing door 7, and the line can be extended smoothly.

ず、延線を続行できる。(Effects of the invention) This invention has the above-described configuration, and the hanging wire wheel provided on the yoke serves as a leading roller, allowing multiple coaxial cables to be extended along the messenger wire. At this time, the suspension wheel is placed on the messenger wire and the yoke is suspended, so the yoke does not hang down from the messenger wire, and even if the wire is not stretched under high tension, this yoke and the cables connected to the yoke can be easily connected. The sender wire will not get caught in obstacles such as lines below. Moreover, since this suspension wheel is located at a position corresponding to the center of a large number of chains for connecting coaxial cables, a large number of coaxial cables are always held in a fixed position and extended. In addition, since both sides of the wire suspension wheel are closed with supports and opening/closing doors, even if the yoke itself loses its balance due to differences in the tension of multiple coaxial cables, wind pressure, shaking of the wire rope, etc. The yoke does not come off the wire and the wire can be continued.

ーへのこの考案の着脱が容易である。 In addition, in the case of CATV cables, there are many branch points where the cable is added or removed, so the yoke is often removed from the messenger wire each time during cable extension, but with this idea, one side of the suspension wheel is equipped with an opening/closing door. This makes it easy to attach and detach this device to the messenger wire.
