Description

本発明は、電柱間等の所要区間に張設した支持線に沿って架設し、該所要区間に配設する通信用や電力用のケーブルを吊支するのに用いる螺旋状ケーブルハンガーの架設方法に関する。   The present invention relates to a method for laying a helical cable hanger that is installed along a support line stretched in a required section such as between utility poles and is used to suspend a communication or power cable disposed in the required section. About.

一般的に、この種の螺旋状ケーブルハンガーは、金属芯線を厚肉の合成樹脂層で被覆した構造であり、電柱間等の所要区間に予め張設されたメッセンジャーワイヤーや自己保持ケーブルの如き支持線に対し、その一端側から1.5m〜数m程度の長さのものを巻き絡ませ、各々の両端に固着したオスメス嵌合式の合成樹脂製コネクタを利用して順次連結してゆく形で、該所要区間の略全長に亘って架設し、その螺旋の内側に所要本数の通信用ケーブルや電力用ケーブルを通して吊支するようになっている(特許文献1〜3等)。   In general, this type of helical cable hanger has a structure in which a metal core wire is covered with a thick synthetic resin layer, and is supported by a messenger wire or a self-holding cable that is stretched in advance in a required section such as between utility poles. The wire is wound about 1.5m to several meters in length from one end side, and is connected sequentially using male and female fitting type synthetic resin connectors fixed to both ends. It is constructed over substantially the entire length of the required section and is suspended through the required number of communication cables and power cables inside the spiral (Patent Documents 1 to 3, etc.).

しかしながら、螺旋状ケーブルハンガーの架設区間が長い場合、支持線に対する該ケーブルハンガーの巻き掛かり量の増加に伴って摺接抵抗が過大になることに加え、元来より支持線には断裂防止のためにある程度の弛みを持たせており、その弛み分によって架設区間の終端側で支持線Lが上り勾配になることから、架設途上で該ケーブルハンガーの始端側の進行が停止してしまい、以降は螺旋ピッチが狭まるだけで設定位置まで送り込めなくなる。また、架設区間は短くとも支持線Lが全体的にある程度以上の上り勾配になっている場合は、同様に始端側の進行が停止してしまうことになる。従って、このような事態に陥った際には、その停止位置に高所作業車を搬入したり、地上から適当な棒具等でケーブルハンガーの始端部を引っ掛けたりして残りの行程を送り込む必要があるが、手作業で多大な労力を要する他、例えば停止位置に建造物等の障害物があったり、川や溝、急傾斜地等に懸かっている場合等、周辺状況によっては送り込み作業自体が極めて困難になる。   However, when the installation section of the spiral cable hanger is long, the sliding contact resistance becomes excessive as the amount of the cable hanger wound around the support wire increases, and the support wire is originally prevented from being broken. Since the support line L has an upward slope on the end side of the installation section due to the slack, the progress of the cable hanger on the start side stops during the installation, and thereafter It becomes impossible to send to the set position only by reducing the helical pitch. In addition, if the support line L has an upward slope of a certain degree or more as a whole even if the erection section is short, the advance on the start end side is similarly stopped. Therefore, when falling into such a situation, it is necessary to carry in the rest of the work by bringing an aerial work vehicle into the stop position or hooking the start end of the cable hanger from the ground with a suitable bar or the like However, depending on the surrounding conditions, such as when there are obstacles such as buildings at the stop position, or when hanging on rivers, trenches, steep slopes, etc. It becomes extremely difficult.

本発明は、上述の事情に鑑みて、螺旋状ケーブルハンガーの架設方法として、架設途上で該ケーブルハンガーの始端側の進行が停止しても、当初の送り込み側からの簡単な操作により、残りの行程を支障なく送り込んで設定位置まで確実に到達させ得る手段を提供することを目的としている。   In view of the circumstances described above, the present invention provides a method for laying a helical cable hanger. Even if the advancement of the cable hanger stops during the erection process, the remaining operation can be performed by a simple operation from the initial feeding side. An object of the present invention is to provide means capable of sending the stroke without any hindrance and reliably reaching the set position.

When the spiral cable hanger H with the leading member 3 fastened to the start end is wound around and sent to the other end side of the support line L, the progress of the start end side of the cable hanger H slows or stops. Then, the cable hanger H is sent to the support wire L at least for the installation length and stays there, and then the wire rod 4 provided with a locking member (plate body 5) at the tip is supported from one end side of the support wire L. By feeding along the line L, engaging the engaging member with the leading member 3 of the cable hanger H, and further feeding the wire rod 4, the start end side of the staying spiral cable hanger H is moved forward. Tow the support line L It is characterized in that to reach the end side.

請求項3の発明は、上記請求項2の螺旋状ケーブルハンガーの架設方法において、螺旋状ケーブルハンガーHの先導部材3が内側に支持線Lを通すリング部3aを有すると共に、通線ロッド4の係止部材が該リング部3aを通過不能な大きさの板体5よりなることを特徴としている。   The invention of claim 3 is the method of installing the spiral cable hanger according to claim 2, wherein the leading member 3 of the spiral cable hanger H has a ring portion 3a through which the support wire L is passed, and the wire rod 4 The locking member is formed of a plate body 5 having a size incapable of passing through the ring portion 3a.

請求項4の発明は、上記請求項1〜3の何れかの螺旋状ケーブルハンガーの架設方法において、螺旋状ケーブルハンガーHが送出ドラム12に巻装された無連結長尺のものからなり、該送出ドラム12の巻出し回転と、この送出ドラム12を枢支するドラム取付台11の回転とにより、該ケーブルハンガーHを螺旋進行方向に捩れ回転させつつ連続的に送り出すことを特徴としている。   The invention of claim 4 is a method of laying a spiral cable hanger according to any one of claims 1 to 3, wherein the spiral cable hanger H is an unconnected long one wound around a delivery drum 12, The cable hanger H is continuously sent out while being twisted and rotated in the spiral traveling direction by the unwinding rotation of the feeding drum 12 and the rotation of the drum mount 11 that pivotally supports the feeding drum 12.

請求項5の発明は、上記請求項1〜4の何れかの螺旋状ケーブルハンガーの架設方法において、通線ロッド4によって螺旋状ケーブルハンガーHの始端側を支持線Lの他端側へ到達させて固定したのち、該通線ロッド4の先端にケーブル牽引用索体7を接続し、該通線ロッド4の引戻しによって所要のケーブルを螺旋状ケーブルハンガーHの内側を通して配設することを特徴としている。   According to a fifth aspect of the present invention, in the method for constructing the helical cable hanger according to any one of the first to fourth aspects, the starting end side of the helical cable hanger H is made to reach the other end side of the support line L by the wire rod 4. After the cable rod is fixed, the cable pulling cable body 7 is connected to the tip of the wire rod 4, and the required cable is arranged through the inside of the spiral cable hanger H by pulling back the wire rod 4. Yes.

次に、本発明による効果について、図面の参照符号を付して説明する。まず、請求項1の発明に係る螺旋状ケーブルハンガーの架設方法によれば、螺旋状ケーブルハンガーHを支持線Lの一端側から巻き絡ませて他端側へ送り込んでゆく過程で、該ケーブルハンガーHの始端側の進行が鈍化又は停止した際に、該ケーブルハンガーHを少なくとも架設長さ分まで支持線Lに送り込んで滞留させ、次いで通線ロッド4を支持線Lの一端側から該支持線Lに沿って送り込み、その先端の係止部材(板体5)をケーブルハンガーHの始端の先導部材3に係合させて更に該通線ロッド4を送り込むことにより、滞留していた螺旋状ケーブルハンガーHの始端側を前方へ牽引するようにしている。従って、架設区間が長い場合に、支持線Lに対する該ケーブルハンガーHの巻き掛かり量の増加に伴う摺接抵抗が過大になることに加え、架設区間の終端部で支持線Lがその弛み分によって急な上り勾配になることにより、また架設区間は短くとも支持線Lが全体的に上り勾配であることより、架設途上で該ケーブルハンガーHの始端側が停止して送り込み不能になり、しかも周辺状況から停止位置での送り込み作業が困難な事態に陥っても、当初の作業位置である支持線Lの一端側から通線ロッド4を送り込むだけの極めて簡単な操作により、残りの行程を支障なく送り込んで設定位置まで確実に到達させることができる。   Next, effects of the present invention will be described with reference numerals in the drawings. First, according to the construction method of the spiral cable hanger according to the invention of claim 1, in the process of winding the spiral cable hanger H from one end side of the support wire L and feeding it to the other end side, The cable hanger H is sent to the support line L at least as much as the installation length and stays at the start end side of the support wire L when the advancement of the start end side of the support wire L is stopped or stopped. , The engaging member (plate body 5) at the front end is engaged with the leading member 3 at the starting end of the cable hanger H, and the wire rod 4 is further fed, so that the retained helical cable hanger The start end side of H is pulled forward. Therefore, when the installation section is long, the sliding resistance accompanying an increase in the amount of the cable hanger H wound around the support line L becomes excessive, and the support line L is caused by the slack of the end of the installation section. Due to the steep ascending slope and the support section L ascending slope as a whole even if the erection section is short, the starting end side of the cable hanger H stops during the erection, and the surrounding situation becomes impossible. Even if the feeding work at the stop position becomes difficult, the remaining stroke can be sent without any trouble by an extremely simple operation of feeding the wire rod 4 from one end side of the support line L which is the original working position. Can reliably reach the set position.

請求項2の発明によれば、通線ロッド4を送り込んでゆく際、先端に止着したガイド部材6が支持線Lを摺動自在に抱持しているから、その先端側が先に送り込まれているケーブルハンガーHの螺旋の内側から外れることなく進行すると共に、このガイド部材6に枢支された係止部材(板体5)がケーブルハンガーHと接触しても自動的に回動して引っ掛かりを生じず、もって該通線ロッド4の進行が妨げられない。   According to the invention of claim 2, since the guide member 6 fixed to the tip end slidably holds the support wire L when the wire rod 4 is sent, the tip end side is sent first. The cable hanger H advances without being detached from the inside of the spiral of the cable hanger H, and automatically rotates even if the locking member (plate body 5) pivotally supported by the guide member 6 contacts the cable hanger H. No catching occurs, and thus the progress of the wire rod 4 is not hindered.

請求項3の発明によれば、螺旋状ケーブルハンガーHの先導部材3が内側に支持線Lを通すリング部3aを有すると共に、通線ロッド4の係止部材が該リング部3aを通過不能な大きさの板体5よりなるから、該板体5が先導部材3のリング部3aに確実に係合して牽引作用を発揮できる。   According to the invention of claim 3, the leading member 3 of the helical cable hanger H has the ring portion 3a through which the support wire L is passed, and the locking member of the wire rod 4 cannot pass through the ring portion 3a. Since it consists of the board | plate body 5 of a magnitude | size, this board body 5 can engage with the ring part 3a of the leading member 3, and can exhibit a traction effect | action.

請求項4の発明によれば、螺旋状ケーブルハンガーHとして無連結長尺のものを用い、これを巻装した送出ドラム12から螺旋進行方向に捩れ回転させつつ連続的に送り出し、そのまま支持線Lに巻き絡めて送り込む形で架設できるから、短尺の螺旋状ケーブルハンガーのように順次接続してゆく煩雑な作業が不要になり、少ない労力で高能率の架設作業を行える。また、このような無連結長尺のケーブルハンガーHでは、架設状態で破損し易いコネクタ部分がないので優れた耐久性を発揮すると共に、製造時の長尺物から短尺単位に切断する必要がなく、且つ短尺物のように両端にコネクタを止着する必要もないから、短尺物に比較して材料コスト及び加工コストを大幅に低減できるという利点がある。   According to the fourth aspect of the present invention, an unconnected long length is used as the helical cable hanger H, and it is continuously sent out while being twisted and rotated in the direction of spiral movement from the delivery drum 12 around which the helical cable hanger H is wound. Since it can be erected by being wound around and fed, it does not require the troublesome work of sequentially connecting like a short helical cable hanger, and high-efficiency erection work can be performed with little effort. In addition, such an unconnected long cable hanger H exhibits excellent durability because there is no connector portion that is easily damaged in the installed state, and there is no need to cut from a long object during manufacture to a short unit. In addition, since it is not necessary to attach connectors to both ends as in the case of a short object, there is an advantage that the material cost and the processing cost can be greatly reduced as compared with the short object.

請求項5の発明によれば、進行停止したケーブルハンガーHの残り行程の送り込みに用いた通線ロッド4を引き戻す際、その先端にケーブル牽引用索体7を接続することにより、そのまま所要のケーブルを螺旋状ケーブルハンガーHの内側に引き込んで配設できるから、ケーブルハンガーHの架設からケーブル配設までの作業を極めて能率よく行える。   According to the fifth aspect of the present invention, when the wire rod 4 used for feeding the remaining stroke of the cable hanger H that has stopped moving is pulled back, the cable pulling rope 7 is connected to the tip of the wire rod 4 so that the required cable can be used. Since the cable hanger H can be drawn into the inside of the spiral cable hanger H, the work from the installation of the cable hanger H to the cable arrangement can be performed very efficiently.

以下に、本発明に係る螺旋状ケーブルハンガーの架設方法において、該螺旋状ケーブルハンガーとして無連結長尺のものを用いた一実施形態について、図面を参照して具体的に説明する。   In the following, an embodiment in which a spiral cable hanger according to the present invention uses a non-connected long one as the spiral cable hanger will be specifically described with reference to the drawings.

この螺旋状ケーブルハンガーの架設方法では、まず図1で示すように、電柱P1,P2間に予め張設されているメッセンジャーワイヤーや自己保持ケーブルの如き支持線Lに対し、送り出し装置1から連続的に送り出される無連結長尺の螺旋状ケーブルハンガーHを該支持線Lの一端側から巻き絡め、送り込み手段2を介して該支持線Lに吊支される状態で送り込んでゆく。このとき、螺旋状ケーブルハンガーHは、送り出し装置1の送出ドラム12が送出方向に垂直面内で回転すると同時に水平面内でも回転動作することにより、螺旋進行方向へ捩れ回転しつつ送出されることから、支持線Lに対して自動的に巻き絡まってゆく形になる。   In this method of laying the helical cable hanger, first, as shown in FIG. 1, continuous from the feeding device 1 to a support line L such as a messenger wire or a self-holding cable previously stretched between the utility poles P1 and P2. The unconnected long helical cable hanger H fed to the cable is wound from one end side of the support line L, and is fed in a state of being suspended from the support line L via the feed means 2. At this time, the spiral cable hanger H is sent out while being twisted and rotated in the spiral traveling direction by rotating the delivery drum 12 of the delivery device 1 in a plane perpendicular to the delivery direction and simultaneously rotating in the horizontal plane. The support wire L is automatically wound around the support line L.

送り出し装置1は、図3〜図6に示すように、一端側に回転駆動手段としての手動回転ハンドル15を設けた架台10、この架台10上に垂直枢軸13aを介して水平面内回転自在に枢支されたドラム取付台11、該ドラム取付台11の垂直取付板11bの前面上部に水平枢軸13bを介して垂直面内回転自在に枢支された送出ドラム12、これらドラム取付台11と送出ドラム12とを連動回転させる回転伝達手段14、ドラム取付台11の垂直取付板11bの背面側に立設された支柱11cの頂端に固着された縦短円筒状の送出ガイド筒16、下端でドラム取付台11の水平基部11aに止着されて上部側が送出ドラム12を挟むように逆ハの字状に配置した一対の帯板状ガイドカバー17,17、より構成されている。   As shown in FIGS. 3 to 6, the delivery device 1 includes a gantry 10 provided with a manual rotation handle 15 as a rotation driving means on one end side, and is pivoted on the gantry 10 via a vertical pivot 13 a so as to be rotatable in a horizontal plane. A supported drum mounting base 11, a delivery drum 12 pivotally supported on a front upper portion of a vertical mounting plate 11b of the drum mounting base 11 via a horizontal pivot shaft 13b, and rotatable in a vertical plane, the drum mounting base 11 and the delivery drum 12 is a rotation transmission means 14 that rotates in conjunction with the drum 12, a vertically short cylindrical delivery guide cylinder 16 fixed to the top end of a column 11c that is erected on the back side of the vertical mounting plate 11b of the drum mounting base 11, and a drum mounting at the lower end. It is composed of a pair of strip-shaped guide covers 17 and 17 that are fixed to the horizontal base 11a of the table 11 and arranged in an inverted C shape so that the upper side sandwiches the delivery drum 12.

架台10は、厚肉帯板10aの一端側下面と他端側上面とに、各々該帯板10aの長手方向に対して直交方向に沿う角筒状の脚杆10b,10cが固着されており、両脚杆10b,10cの各両端部にボルトからなるアジャスタ10d,10dを備えると共に、脚杆10cの両端にはキャスター10e,10eが設けてある。また、手動回転ハンドル15は、上部が二段L字状に曲折した金属棒材からなり、図7に示すように、下端部が厚肉帯板10aに枢着した垂直枢軸15aに屈折継手15bを介して傾動自在で且つ相対回転不能に連結している。しかして、ドラム取付台11と手動回転ハンドル15の両垂直枢軸13a,15aに固設されたスプロケット18a,18b間にチェーン18cが嵌装されており、手動回転ハンドル15の回転操作によってドラム取付台11が垂直面内で回転するようになっている。   In the gantry 10, square cylindrical leg rods 10 b and 10 c that are orthogonal to the longitudinal direction of the band plate 10 a are fixed to the lower surface on one end side and the upper surface on the other end side of the thick band plate 10 a, respectively. Further, adjusters 10d and 10d made of bolts are provided at both ends of both leg rods 10b and 10c, and casters 10e and 10e are provided at both ends of the leg rod 10c. Further, the manual rotation handle 15 is made of a metal bar whose upper part is bent into a two-stage L shape, and as shown in FIG. 7, the lower end part is pivotally attached to a vertical pivot 15a that is pivotally attached to the thick strip 10a. It can be tilted through and connected in a relatively non-rotatable manner. Thus, a chain 18c is fitted between the sprockets 18a and 18b fixed to the vertical pivot shafts 13a and 15a of the drum mount 11 and the manual rotary handle 15, and the drum mount is rotated by the manual rotary handle 15 being rotated. 11 rotates in a vertical plane.

一方、ドラム取付台11の垂直枢軸13aの上端には駆動側傘歯歯車14aが固着されると共に、該ドラム取付台11の水平基部11a上にはその回転中心を通って且つ送出ドラム12の水平枢軸13bと平行な回転軸14cが軸受19,19を介して回転自在に配設され、該回転軸14cに固着した従動側傘歯歯車13bが駆動側傘歯歯車14aと噛合している。そして、該回転軸14cの後端と送出ドラム12の水平枢軸13bの後端とに固設されたスプロケット18d,18e間にチェーン18fが嵌装されており、これによってドラム取付台11の水平面内での回転に伴って送出ドラム12を垂直面内で連動回転させる回転伝達手段14を構成している。   On the other hand, a drive-side bevel gear 14 a is fixed to the upper end of the vertical pivot 13 a of the drum mounting base 11, and the horizontal base 11 a of the drum mounting base 11 passes through its rotation center and is horizontal to the delivery drum 12. A rotating shaft 14c parallel to the pivot shaft 13b is rotatably disposed through bearings 19 and 19, and a driven bevel gear 13b fixed to the rotating shaft 14c meshes with the driving bevel gear 14a. A chain 18f is fitted between sprockets 18d and 18e fixed to the rear end of the rotating shaft 14c and the rear end of the horizontal pivot shaft 13b of the delivery drum 12. The rotation transmission means 14 is configured to rotate the delivery drum 12 in an interlocking manner in the vertical plane in accordance with the rotation.

送出ドラム12は、ドラム本体12aの前後両端に径大の円形端板12b,12cが水平枢軸13bを介して同心に嵌着されており、前部側の円形端板12bを取り外して螺旋状ケーブルハンガーHの巻き束H0をドラム本体12aに巻装し、該円形端板12bを装着した上で、図3及び図4に示すように、巻き束H0から繰り出した螺旋状ケーブルハンガーHの始端を送出ガイド筒16を通して上方へ引き出すようになっている。なお、螺旋状ケーブルハンガーHの巻き束H0としては、通常では全長40〜60m程度のものが使用されるが、特に架設区間の距離が大きい場合に対応してより全長の長いものを用いることもある。   The delivery drum 12 has circular end plates 12b, 12c having large diameters concentrically fitted to the front and rear ends of the drum body 12a via a horizontal pivot shaft 13b, and the front end circular end plate 12b is removed to form a spiral cable. The winding bundle H0 of the hanger H is wound around the drum body 12a, and the circular end plate 12b is mounted. Then, as shown in FIG. 3 and FIG. It is pulled out upward through the delivery guide tube 16. In addition, as the bundle H0 of the helical cable hanger H, one having a total length of about 40 to 60 m is normally used, but a longer one may be used particularly when the distance of the construction section is large. is there.

螺旋状ケーブルハンガーHの始端には、支持線Lからの離脱を防止する先導部材3が止着される。この先導部材3は、ケーブルハンガーHと同様の線材(金属芯線を合成樹脂層で被覆)を曲成したものであり、図8に示すように、該線材を円形に巻いて形成したリング部3aと、その軸方向に平行に各々反対側へ張出する直線状端部3b,3cとで構成されており、一方の直線状端部3bとケーブルハンガーHの始端とを差込み式連結具31で連結した状態で、材料弾性を利用して両直線状端部3b,3cを引き離すようにしてリング部3aの重なり部分を開き、図示のように該リング部3a内に支持線Lを通すことにより、該ケーブルハンガーHの始端が支持線Lから離脱不能となる。   A leading member 3 that prevents separation from the support line L is fixed to the starting end of the helical cable hanger H. The leading member 3 is formed by bending a wire similar to the cable hanger H (a metal core wire is covered with a synthetic resin layer), and as shown in FIG. 8, a ring portion 3a formed by winding the wire in a circular shape. And linear end portions 3b and 3c extending in opposite directions in parallel to the axial direction, and one linear end portion 3b and the start end of the cable hanger H are connected by a plug-in connection tool 31. In the connected state, by utilizing the material elasticity, the overlapping part of the ring part 3a is opened so as to separate the two linear ends 3b and 3c, and the support line L is passed through the ring part 3a as shown in the figure. The starting end of the cable hanger H cannot be detached from the support line L.

送り込み手段2は、図7で示す送りローラー具20と、図1に示す電動回転工具21とで構成される。その送りローラー具20は、基板22の上面に一対のローラ23,24が回転自在に並設され、一方のローラ23の回転軸23aに一体化した六角軸23bが該基板22の下面に突出しており、また基板22の下面側には斜行する取付溝22aが形成されると共に、該基板22の側方にカラビナ25が付設されている。なお、ローラ23の表層部とローラ24の全体はウレタンゴム等の弾性材料にて形成されている。   The feeding means 2 includes a feeding roller tool 20 shown in FIG. 7 and an electric rotary tool 21 shown in FIG. In the feed roller device 20, a pair of rollers 23, 24 are rotatably arranged in parallel on the upper surface of the substrate 22, and a hexagonal shaft 23 b integrated with the rotation shaft 23 a of one roller 23 protrudes from the lower surface of the substrate 22. In addition, an oblique mounting groove 22 a is formed on the lower surface side of the substrate 22, and a carabiner 25 is attached to the side of the substrate 22. The surface layer of the roller 23 and the entire roller 24 are made of an elastic material such as urethane rubber.

この送り込み手段2では、支持線Lに取付溝22aを嵌合させ、カラビナ25を該支持線Lに掛着し、もって該支持線Lに跨嵌した送りローラー具20の六角軸23bに電動回転工具21の駆動軸筒を連結する。そして、予め始端側の一部を該支持線Lに巻き絡めた螺旋状ケーブルハンガーHの線材を両ローラ23,24間に挟み込み、この状態で電動回転工具21を駆動することにより、回転駆動するローラ23と従動回転するローラ24とで該ケーブルハンガーHを支持線Lに沿って送り込むことができる。なお、ケーブルハンガーHの始端側を支持線Lに巻き絡ませてから、電動回転工具21によって送り込む一連の作業は、通常では作業者が高所作業車のゴンドラに乗って行うことになるが、支持線Lの位置がさほど高くない場合は脚立を利用して行うこともできる。   In this feeding means 2, the mounting groove 22 a is fitted to the support line L, the carabiner 25 is hooked on the support line L, and the electric rotation is performed on the hexagonal shaft 23 b of the feed roller device 20 straddling the support line L. The drive shaft cylinder of the tool 21 is connected. Then, the wire rod of the spiral cable hanger H in which a part of the start end side is wound around the support wire L is sandwiched between the rollers 23 and 24, and the electric rotary tool 21 is driven in this state to drive the rotation. The cable hanger H can be fed along the support line L by the roller 23 and the roller 24 that is driven to rotate. Note that a series of operations in which the cable hanger H is wound around the support line L and then fed by the electric rotary tool 21 is usually performed by a worker on a gondola of an aerial work vehicle. When the position of the line L is not so high, it can be performed using a stepladder.

このようにして螺旋状ケーブルハンガーHを送り出し装置1から連続的に送り出しながら、送り込み手段2によって支持線Lに沿って送り込んでゆけば、架設区間つまり電柱P1,P2間の距離が短い場合や支持線Lが下り勾配である場合では、そのまま該ケーブルハンガーHの始端を支持線Lの他端側の設定位置まで到達させることができる。しかるに、螺旋状ケーブルハンガーHの架設区間が長い場合、支持線Lに対する該ケーブルハンガーHの巻き掛かり量の増加に伴う摺接抵抗が過大になることに加え、一般的に支持線Lには断裂防止のためにある程度の弛みを持たせており、その弛み分によって架設区間の終端部で支持線Lが急な上り勾配になることから、図2(a)に示すように送り込まれるケーブルハンガーHの前部側の螺旋ピッチが狭まる形で、始端の前進が鈍化して遂には停止してしまうことになる。また、架設区間は短くとも支持線Lが全体的に上り勾配である場合には、同様に架設途上で始端が進行停止してしまうことがある。そして、このように螺旋状ケーブルハンガーHの始端が前進不能に陥った際には、その停止位置に他の高所作業車を搬入したり、地上から適当な棒具等で該ケーブルハンガーHの始端部を引っ掛けたりして残りの行程を送り込む必要があるが、手作業で多大な労力を要する他、例えば停止位置に建造物等の障害物があったり、川や溝、急傾斜地等に懸かっている場合等、周辺状況によっては作業自体が不可能になる。   Thus, if the spiral cable hanger H is continuously sent out from the sending device 1 and is sent along the support line L by the sending means 2, the construction section, that is, the distance between the utility poles P1 and P2 is short or supported. When the line L has a downward slope, the start end of the cable hanger H can be reached as it is to the set position on the other end side of the support line L. However, when the installation section of the spiral cable hanger H is long, the sliding contact resistance with the increase in the amount of winding of the cable hanger H with respect to the support wire L becomes excessive, and the support wire L generally breaks. The cable hanger H fed as shown in FIG. 2 (a) has a certain amount of slack to prevent it, and the slack amount causes the support line L to have a steep upward slope at the end of the installation section. As the spiral pitch on the front side becomes narrower, the advance of the starting edge slows down and eventually stops. In addition, even if the installation section is short, if the support line L is entirely ascending, the starting end may be similarly stopped during the installation. Then, when the starting end of the spiral cable hanger H becomes unable to move forward in this way, another work vehicle at a high place is carried to the stop position, or the cable hanger H is removed from the ground with an appropriate bar or the like. It is necessary to hook the start end and feed the rest of the process, but it requires a lot of manual labor.For example, there are obstacles such as buildings at the stop position, and it is hung on rivers, trenches, steep slopes, etc. The work itself becomes impossible depending on the surrounding situation.

そこで、本発明の架設方法では、支持線Lに巻き絡ませた螺旋状ケーブルハンガーHの始端側の進行が鈍化又は停止した段階で、該ケーブルハンガーHを少なくとも架設長さ分まで支持線Lに送り込んで滞留させる。そして、送り出し装置1による送り出しの停止後に、図2(b)に示すように収納リール40から繰り出した通線ロッド4を支持線Lの一端側から該支持線Lに沿って送り込んでゆくことにより、その先端に設けた係止部材(板体5…図9〜図12参照)をケーブルハンガーHの始端の先導部材3に係合させ、更に通線ロッド4を送り込むことによって該係合部分でケーブルハンガーHを前方へ牽引し、その始端を支持線Lの他端側の設定位置まで到達させる。なお、41は支持線Lの一端側に係着したハンガーローラーであり、両端をフック形にしたU字状芯線に多数の丸板状ローラーが嵌装されており、これに通線ロッド4を通して送り込むようにしている。   Therefore, in the erection method of the present invention, when the progress of the spiral cable hanger H wound around the support line L is slowed or stopped, the cable hanger H is fed to the support line L at least as much as the erection length. Let it stay. Then, after stopping the feeding by the feeding device 1, as shown in FIG. 2B, the wire rod 4 fed out from the storage reel 40 is fed along the support line L from one end side of the support line L. The engaging member (the plate body 5... See FIG. 9 to FIG. 12) provided at the tip is engaged with the leading member 3 at the starting end of the cable hanger H, and further the feed rod 4 is fed to the engaging portion. The cable hanger H is pulled forward, and the starting end thereof reaches the set position on the other end side of the support line L. A hanger roller 41 is attached to one end of the support line L, and a large number of round plate-like rollers are fitted to U-shaped core wires having hooks at both ends. I try to send it in.

このような通線ロッド4は、従来より架設された螺旋状ケーブルハンガーの内側に通信用ケーブルや電力用ケーブルを引き込んで吊支するのに汎用されているものであり、一般的にFRP(繊維強化プラスチック)製で非常に腰の強い線材からなる。しかして、本実施形態では、図9に示すように、該通線ロッド4の先端に固着した首振りねじ筒型の接続金具42と、支持線Lを摺動自在に抱持する金属製のガイド部材6との螺合連結部に、係止部材としての板体5を枢支金具52及び連結リング53を介して吊設している。この板体5は、枢支金具52の枢支部を中心として支持線配設方向と直交する面内で回動自在であって、且つ連結リング53の介在によって前後方向にも揺動可能である。この場合、ガイド部材6で支持線Lを抱持した通線ロッド4の先端側をケーブルハンガーHの螺旋の内側に通してゆく際、板体5が該ケーブルハンガーHと接触しても図10の仮想線の如く自動的に回動して引っ掛かりを生じず、もって通線ロッド4の進行が妨げられない。   Such a wire rod 4 is generally used to draw and suspend a communication cable or a power cable inside a spiral cable hanger that has been conventionally installed, and is generally FRP (fiber Made of reinforced plastic) and made of very stiff wire. Thus, in this embodiment, as shown in FIG. 9, a swing-screw cylindrical connection fitting 42 fixed to the tip of the wire rod 4 and a metal slidably holding the support wire L are provided. A plate body 5 as a locking member is suspended from a threaded connection portion with the guide member 6 via a pivotal support member 52 and a connection ring 53. The plate body 5 is rotatable in a plane orthogonal to the support line arrangement direction with the pivotal support portion of the pivotal support metal 52 as the center, and can also swing in the front-rear direction by the interposition of the connecting ring 53. . In this case, when the leading end side of the wire rod 4 holding the support wire L by the guide member 6 is passed through the inside of the spiral of the cable hanger H, even if the plate 5 comes into contact with the cable hanger H, FIG. As shown in the virtual line, it automatically rotates and does not get caught, so that the progress of the wire rod 4 is not hindered.

図11で示すように、板体5は、頂部に透孔51を有する三角部5aの底辺側に、その底辺長より大きい径の半円部5bが一体したプラスチック製平板からなり、半円部5bが螺旋状ケーブルハンガーHの先導部材3のリング部3a(図示仮想線)を通過できない大きさになっており、三角部5aの頂部に設けた透孔51に偏平な枢支金具52が連結リング53を介して取り付けられている。また、ガイド部材6は、ヒンジ部61を介して開閉可能な一対の曲成板片6a,6bからなり、その閉じ合わせ状態において内側の筒状部62と外側の係着部63を形成すると共に、曲成板片6bに固着されたねじ軸64が係着部63から後方へ突出するように構成されている。そして、板体5は、ガイド部材6の筒状部62に支持線Lを抱持させた状態で、そのねじ軸64を通線ロッド4の接続金具42に螺挿して連結する際に、枢支金具52の取付孔52aに該ねじ軸64を挿通することより、その螺合連結部に吊設される。   As shown in FIG. 11, the plate body 5 is made of a plastic flat plate in which a semicircular portion 5b having a diameter larger than the base length is integrally formed on the bottom side of a triangular portion 5a having a through hole 51 at the top portion. 5b cannot pass through the ring portion 3a (imaginary line) of the leading member 3 of the spiral cable hanger H, and a flat pivot metal fitting 52 is connected to the through hole 51 provided at the top of the triangular portion 5a. It is attached via a ring 53. The guide member 6 includes a pair of bent plate pieces 6a and 6b that can be opened and closed via a hinge portion 61, and forms an inner cylindrical portion 62 and an outer engaging portion 63 in the closed state. The screw shaft 64 fixed to the bent plate piece 6b is configured to protrude rearward from the engaging portion 63. The plate body 5 is pivoted when the threaded shaft 64 is screwed into the connection fitting 42 of the wire rod 4 in a state where the support line L is held by the cylindrical portion 62 of the guide member 6. By inserting the screw shaft 64 through the mounting hole 52a of the support metal 52, the screw shaft 64 is suspended.

かくして先端部に板体5を取り付けた通線ロッド4を滞留している螺旋状ケーブルハンガーHの内側に通して送り込んでゆくと、図12に示すように、該通線ロッド4の先端のガイド部材6がケーブルハンガーHの先導部材3のリング部3aを通過するが、板体5が該リング部3aを通過できずに係合することになる。従って、更に該通線ロッド4を送り込んでゆくことにより、板体5を介してケーブルハンガーHが前方へ牽引され、滞留状態で狭まっていた螺旋ピッチが拡がってゆく形で、その始端が支持線Lの他端側の設定位置まで支障なく到達する。   Thus, when the wire rod 4 having the plate body 5 attached to the tip portion is fed through the staying spiral cable hanger H, as shown in FIG. 12, a guide for the tip of the wire rod 4 is provided. The member 6 passes through the ring portion 3a of the leading member 3 of the cable hanger H, but the plate body 5 is engaged without being able to pass through the ring portion 3a. Accordingly, when the wire rod 4 is further fed, the cable hanger H is pulled forward through the plate body 5, and the spiral pitch that has been narrowed in the staying state is expanded, and the starting end thereof is the support wire. It reaches the set position on the other end side of L without any trouble.

設定部位に到達したケーブルハンガーHの始端部は、常法通りに適当な固定金具や針金等を用いて支持線Lあるいは電柱P2に固定する。この始端側を固定したケーブルハンガーHは、その全体が所望の螺旋ピッチになるように終端側から引戻した上で、終端側の設定位置で切断して同様に支持線Lあるいは電柱P1に固定する。なお、ケーブルハンガーHの余剰の引き出し分は、送り出し装置1の回転駆動手段を逆回転操作することにより、送出ドラム12に巻き戻して回収すればよい。   The starting end of the cable hanger H that has reached the set site is fixed to the support line L or the utility pole P2 using an appropriate fixing bracket, wire, or the like as usual. The cable hanger H with the start end side fixed is pulled back from the end side so that the whole has a desired spiral pitch, and then cut at a set position on the end side and similarly fixed to the support line L or the utility pole P1. . In addition, what is necessary is just to unwind the cable hanger H and to collect | recover it by rewinding to the sending drum 12 by carrying out reverse rotation operation of the rotation drive means of the sending apparatus 1. FIG.

なお、螺旋状ケーブルハンガーHを架設したのち、通線ロッド4も引き戻して収納リール40に巻装することになるが、その引き戻し操作を利用して所要の通信用又は電力用ケーブルの配設を行える。例えば図13に示すように、通線ロッド4を引き戻す前に、その先端の接続金具42から板体5及びガイド部材6を取外し、代わりにロープ接続用のリング金具43を該接続金具42に螺着し、通信用又は電力用ケーブル(図示省略)に繋がるケーブル牽引用ロープ7を留め金7aを介して結び付ける。そして、該通線ロッド4を引き戻すことにより、所要のケーブルをケーブルハンガーHの螺旋の内側に引き込んで吊支させることができる。   In addition, after installing the helical cable hanger H, the wire rod 4 is also pulled back and wound around the storage reel 40. However, the required communication or power cable is arranged by using the pull-back operation. Yes. For example, as shown in FIG. 13, before pulling back the wire rod 4, the plate body 5 and the guide member 6 are removed from the connection fitting 42 at the tip, and instead a ring fitting 43 for connecting the rope is screwed to the connection fitting 42. A cable pulling rope 7 connected to a communication or power cable (not shown) is connected through a clasp 7a. Then, by pulling back the wire rod 4, the required cable can be drawn inside the spiral of the cable hanger H and suspended.

上記実施形態では螺旋状ケーブルハンガーHとして無連結長尺のものを用いているが、本発明では従来より汎用されている短尺のもの、つまり両端にオスメス嵌合式のコネクタを設けたものも使用可能である。このような短尺のケーブルハンガーを用いる場合、予めコネクタを介して多数本を接続して長尺にしたものを送り出し装置1の送出ドラム12に巻装し、前記実施形態における無連結長尺のものと同様にして螺旋進行方向に捩れ回転させつつ連続的に送り出し、そのまま支持線Lの一端側から巻き絡ませて他端側へ送り込んでゆくこともできるが、送り出し装置1を用いずに支持線Lの一端側から順次に巻き絡ませて接続してゆく方法も採用可能である。   In the above embodiment, the unconnected long one is used as the helical cable hanger H. However, in the present invention, a short one that has been widely used conventionally, that is, one having male and female fitting connectors at both ends can be used. It is. When such a short cable hanger is used, a long one that is previously connected to a long length via a connector is wound around the delivery drum 12 of the delivery device 1, and the unconnected length of the embodiment is used. In the same manner as described above, it is possible to continuously feed while twisting and rotating in the spiral traveling direction, and to wind the support wire L from one end side as it is and feed it to the other end side. It is also possible to adopt a method in which the wires are wound and connected sequentially from one end side.

ただし、実施形態のように無連結長尺の螺旋状ケーブルハンガーHを用いれば、短尺のもののように順次接続してゆく煩雑な作業が不要になり、少ない労力で高能率の架設作業を行える。また、無連結長尺のケーブルハンガーHでは、架設状態で破損し易いコネクタ部分がないので優れた耐久性を発揮すると共に、製造時の長尺物から短尺単位に切断する必要がなく、且つ短尺物のように両端にコネクタを止着する必要もないから、短尺物に比較して材料コスト及び加工コストを大幅に低減できるという利点がある。   However, if the unconnected long helical cable hanger H is used as in the embodiment, the troublesome work of sequentially connecting like a short one becomes unnecessary, and a highly efficient erection work can be performed with little effort. In addition, the unconnected long cable hanger H exhibits excellent durability because there is no connector portion that is easily damaged in the installed state, and it is not necessary to cut from a long object at the time of manufacture to a short unit. Since there is no need to fasten connectors at both ends like a product, there is an advantage that the material cost and the processing cost can be greatly reduced as compared with a short product.

支持線Lは、メッセンジャーワイヤーとして図示しているが、自己保持ケーブルであってもよい。また、該支持線Lの架設区間の両端における止着対象は、電柱P1,P2以外の種々の構造物を包含する。更に、図ではケーブルハンガーHの送り込み装置1及び通線ロッド4の収納リール40を地上に設置しているが、これらを高所作業車のゴンドラに積み込んで作業することも可能である。   The support line L is illustrated as a messenger wire, but may be a self-holding cable. Moreover, the fixation object in the both ends of the construction area of this support line L includes various structures other than utility pole P1, P2. Further, in the drawing, the feeding device 1 for the cable hanger H and the storage reel 40 for the wire rod 4 are installed on the ground, but it is also possible to work by loading them on a gondola of an aerial work vehicle.

螺旋状ケーブルハンガーHの先導部材3としては、支持線Lからの離脱を防止する機能を有しておればよく、様々な形態のものを採用できるが、例示したリング部3aを有する形態では該ケーブルハンガーHと同じ線材の曲成によって容易に安価に製作できるという利点がある。また、通線ロッド4の先端に設ける係止部材としては、螺旋状ケーブルハンガーHの先導部材3と係合してするものであればよく、例示した板体5以外の様々な形状のものを用い得るが、該通線ロッド4の送り込みの際にケーブルハンガーHに引っ掛かるのを防止する上で、支持線配設方向と直交する面内で回動自在に枢支するのがよい。更に、通線ロッド4の先端に設けるガイド部材6、該通線ロッドの先端部とケーブル牽引用ロープ7との接続部分についても、例示以外の様々な形態を採用できる。   As the leading member 3 of the spiral cable hanger H, it is sufficient if it has a function of preventing the separation from the support line L, and various forms can be adopted. However, in the form having the illustrated ring portion 3a, There is an advantage that it can be easily manufactured at low cost by bending the same wire as the cable hanger H. Moreover, as a latching member provided in the front-end | tip of the wire rod 4, what is necessary is just to engage with the lead member 3 of the helical cable hanger H, The thing of various shapes other than the illustrated plate body 5 is sufficient. Although it can be used, in order to prevent the wire rod 4 from being caught by the cable hanger H, it is preferable that the wire rod 4 is pivotally supported in a plane orthogonal to the support wire arrangement direction. Furthermore, the guide member 6 provided at the distal end of the wire rod 4 and the connecting portion between the distal end portion of the wire rod 4 and the cable pulling rope 7 can employ various forms other than those illustrated.

一方、送り出し装置1としては、送出ドラム12の巻出し回転と、この送出ドラム12を枢支するドラム取付台11の回転とにより、螺旋状ケーブルハンガーHを螺旋進行方向に捩れ回転させつつ連続的に送り出す機能を有しておればよく、その回転駆動手段や回転伝達手段14として例示以外の様々な機構を採用できる。例えば、回転駆動手段は、例示した手動回転ハンドル15に代えて、電動モーター等の機械的動力を利用するものを採用してもよい。また、送り込み手段2としても、例示したローラー具20と電動回転工具21との組合せ以外に、様々な送り込み機構を採用できる。なお、作業能率面では劣るが、送り込み手段2を用いずに、手操作で螺旋状ケーブルハンガーHの送り込みを行うこともできる。その他、本発明の架設方法における細部構成については、実施形態以外に種々設計変更可能である。   On the other hand, as the delivery device 1, the spiral cable hanger H is continuously twisted and rotated in the spiral traveling direction by the unwinding rotation of the delivery drum 12 and the rotation of the drum mount 11 that pivotally supports the delivery drum 12. It is only necessary to have a function of feeding to the motor, and various mechanisms other than the examples can be adopted as the rotation driving means and the rotation transmission means 14. For example, instead of the illustrated manual rotation handle 15, the rotation driving means may employ a mechanism that uses mechanical power such as an electric motor. Further, as the feeding means 2, various feeding mechanisms other than the combination of the illustrated roller tool 20 and the electric rotary tool 21 can be adopted. Although it is inferior in terms of work efficiency, the helical cable hanger H can be manually fed without using the feeding means 2. In addition, the detailed configuration in the erection method of the present invention can be variously modified in addition to the embodiment.
