本考案は、管路内にケーブルを布設する場合にけん列側
到達マンホール内において通常のけん引力法では接続等
に必要なケーブル余長が得られないときに用いるケーブ
ルけん引補助具に関するものである。[Detailed description of the invention] This invention is a cable that can be used when the cable is installed in a conduit and the extra cable length required for connection etc. cannot be obtained by the normal traction method in the manhole reaching the tow side. This relates to towing aids.
従来到達マンホール内での接続用のケーブル余長を得る
ためのけん引は、第２図に示す如く、網状の７リーテイ
ンググリツプによりケーブル外被持し、これにけん引ワ
イヤを接続しけん引していた。Conventionally, towing the cable in order to obtain extra cable length for connection within the reaching manhole, as shown in Fig. 2, the cable is supported by a net-like 7-leaving grip, and the towing wire is connected to this and the cable is towed. was.
この方法はけん引時にフリーティンググリップが滑り易
く、ケーブル外被を損傷し易く、さらにケーブルの外被
のみを引っばりケーブルを破損し易いという欠点があっ
た。This method has the disadvantage that the fleeting grip tends to slip during towing, which tends to damage the cable sheath, and furthermore, only the cable sheath is pulled, which tends to damage the cable.
またフリーティンググリップの取付は及び取外しに手間
がかかった。Furthermore, it took time and effort to install and remove the fleeting grip.
本考案はこれらの欠点を解決するため、ケーブルけん引
補助具を用いて、ケーブルの外被には力を加えずしてケ
ーブル余長を得るものであり、以下図面を用いて詳細に
説明する。In order to solve these drawbacks, the present invention uses a cable traction aid to obtain extra cable length without applying force to the cable sheath, and will be described in detail below with reference to the drawings.
第１図はケーブルにケーブルけん引用成端具を取り付け
てケーブルをけん引する方法において、到達マンホール
内における上記けん中法によりケーブルけん引が終了し
た状態を示す。FIG. 1 shows a state in which cable towing has been completed by the above-mentioned towing method in a reaching manhole in a method of towing a cable by attaching a cable towing termination to the cable.
１は到達マンホール、２はダクト口、３はケーブル、４
はケーブルけん引用成端具、５は滑車、６はけん引ワイ
ヤ、７は到達マンホールの側壁である。1 is the reaching manhole, 2 is the duct opening, 3 is the cable, 4
5 is a cable traction termination, 5 is a pulley, 6 is a traction wire, and 7 is a side wall of the reaching manhole.
ダクト口２を経て到達マンホール１内にけん引されたケ
ーブル３はケーブルの先端に取り付けられたケーブルけ
ん引用成端具４に接続されているけん引ワイヤ６により
矢印の方向にけん引されるが、滑車５に阻筐れて進めず
、マンホールの側壁７′１でケーブルをけん引し、接続
等に必要なケーブル余長を得ることができない。The cable 3 that has been towed into the reaching manhole 1 through the duct opening 2 is towed in the direction of the arrow by the traction wire 6 connected to the cable traction termination 4 attached to the tip of the cable. The cable is blocked by the manhole and cannot be moved forward, and the cable is pulled by the side wall 7'1 of the manhole, making it impossible to obtain the extra cable length necessary for connection etc.
そこで従来は第２図に示す如くフリーティンググリップ
によりケーブルをけん引し、余長を得ていた。Conventionally, the cable was pulled by a fleeting grip to obtain extra length, as shown in Figure 2.
第２図において各番号は第１図と同じものを示し、８は
フリーティンググリップである。In FIG. 2, each number indicates the same thing as in FIG. 1, and 8 is a fleeting grip.
フリーティンググリップは網状のグリップをケーブル３
に巻きつけてケーブルを把持し、これをけん引ワイヤ６
により矢印方向にけん引しケーブル余長を得るものであ
る。Fleeting grip is a net-like grip with cable 3
grip the cable by wrapping it around the tow wire 6.
The extra length of the towing cable is obtained by pulling in the direction of the arrow.
第３図は本考案に係るケーブルけん引補助具を用いてケ
ーブル余長を得る方法を示すものであり、９はケーブル
けん引補助具、１０はケーブルけん引用成端具４とケー
ブルけん引補助具９とを固定する手段、１１ばけん引ワ
イヤ接続部である。FIG. 3 shows a method for obtaining extra cable length using the cable traction aid according to the present invention, where 9 is the cable traction aid, 10 is the cable traction termination 4 and the cable traction aid 9. 11 is a traction wire connection.
ケーブル３はケーブルけん引用成端具４を取り付けたま
まの状態でケーブルけん引補助具９内に収容され、先端
部で補助具と接続されている。The cable 3 is housed in the cable traction aid 9 with the cable traction termination 4 still attached, and is connected to the auxiliary tool at its tip.
また、けん引ワイヤ６はケーブルけん引用成端具４から
外され、けん引補助具９のけん引ワイヤ接続部１１に接
続され、矢印方向にけん引し、マンホールの側壁７まで
ケーブル３をけん引して、必要なケーブル余長を得る。Also, the towing wire 6 is removed from the cable towing termination 4, connected to the towing wire connection part 11 of the towing aid 9, and towed in the direction of the arrow, towing the cable 3 to the side wall 7 of the manhole, and then pulling the cable 3 to the side wall 7 of the manhole. Obtain the necessary extra cable length.
マンホールの側壁７まで到達すればけん引補助具９は長
手方向に分割が可能な構造であるので、この状態でけん
引補助具９を取り外す。Since the traction aid 9 has a structure that can be divided in the longitudinal direction once it reaches the side wall 7 of the manhole, the traction aid 9 is removed in this state.
本方法においてはけん引力はケーブルの外被にはかから
ず、すべてケーブルけん引用成端具にかかるため、ケー
ブルを破損することもなく、また作業性も従来のフリー
ティンググリップによる方法に比べて格段に優れている
。In this method, the traction force is not applied to the cable sheath, but is applied entirely to the cable traction termination, so the cable is not damaged and the workability is improved compared to the conventional fleeting grip method. It's extremely good.
第４図はケーブルけん引補助具の一実施例であり、１０
はケーブルけん引用成端具と補助具とを固定する手段と
しての固定ピンである。Figure 4 shows an embodiment of the cable traction aid, with 10
is a fixing pin as a means for fixing the cable traction termination and the auxiliary device.
補助具は長手方向に２分割可能であり、しめ付けにはボ
ルトを用いている。The auxiliary tool can be divided into two in the longitudinal direction, and bolts are used for tightening.
形状は内部にケーブルが収容可能なようにほぼ円筒状で
ある。The shape is approximately cylindrical so that a cable can be accommodated inside.
以上説明したように管路内にケーブルを布設するときに
、けん引用の到達マンホール内にお・いて、接続等のケ
ーブル余長を得る場合に、本考案に係るケーブルけん引
補助具を用いれば、ケーブルの先端に取り付けられてい
るケーブルけん引用成端具がそのま寸利用できるため、
従来の網状のフリーティンググリップを用いた場合に比
べて、次の利点がある。As explained above, when installing a cable in a conduit, if you want to obtain extra cable length for connection etc. in the reaching manhole for towing, if you use the cable traction aid according to the present invention, The cable towing termination attached to the end of the cable can be used as is.
It has the following advantages over the conventional mesh fleeting grip.
（１）ケーブルけん引時の強い張力に耐えられる。(1) Can withstand strong tension during cable towing.
（２）ケーブルの外被及び心線を損傷しない。(2) Do not damage the cable sheath or core wire.
（３）作業能率がよい。(3) Good work efficiency.
