There is.

請求項8の発明によれば、螺旋状ケーブルハンガーHは、金属芯線Mを被覆する合成樹脂層Rがフッ素系樹脂を含んで良好な表面滑性を示すことから、支持線Lに沿って送り出す際の摺接抵抗が少なく、それだけ送り込みが容易になる。   According to the invention of claim 8, the helical cable hanger H is sent out along the support line L because the synthetic resin layer R covering the metal core wire M includes the fluororesin and exhibits good surface slipperiness. The sliding contact resistance at the time is small, and the feeding becomes easier.

請求項9の発明によれば、先に送り出される螺旋状ケーブルハンガーH1の終端に、新たな螺旋状ケーブルハンガーH2の始端を継ぎ足す際、特定構造の差込み噛合式連結具4を用いることから、両ケーブルハンガーH1,H2の各端部を該連結具4のハンガー挿入孔40aに挿嵌するだけでよく、操作的に極めて簡便である上に高い連結強度が得られる。特にケーブルハンガーH1,H2が請求項8のように合成樹脂層Rにフッ素系樹脂を含むものである場合、一般的なかしめ式の連結具では表面での滑りによって抜け易いが、上記差込み噛合式連結具4では係止爪41a…が合成樹脂層Rに食い込むことで確実に抜出防止できる。   According to the invention of claim 9, when the start end of a new spiral cable hanger H2 is added to the end of the spiral cable hanger H1 that is sent out first, the insertion meshing connector 4 having a specific structure is used. It is only necessary to insert the end portions of both the cable hangers H1 and H2 into the hanger insertion hole 40a of the connector 4, which is very simple in operation and provides high connection strength. In particular, when the cable hangers H1 and H2 include a fluororesin in the synthetic resin layer R as in the eighth aspect, the general caulking type connecting device is likely to come off due to sliding on the surface. In FIG. 4, the locking claws 41 a...

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14b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 14b 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4及び図5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. After winding the bundle H0 of the hanger H around the drum body 12a and mounting the circular end plate 12b, as shown in FIGS. 4 and 5, the starting end of the spiral cable hanger H fed out from the bundle H0 is used. 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9に示すように、円形の巻きリング部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の始端とを差込み噛合式連結具4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を引き離す形で巻きリング部3aの重なり部分を拡げて隙間を作り、その隙間から支持線Lを図示のように該リング部3a内に嵌め込んで通すことにより、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. This leading member 3 is formed by bending the same wire material as the cable hanger H (a metal core wire is covered with a synthetic resin layer), and as shown in FIG. 9, a circular winding ring portion 3a and its axial direction It is composed of linear end portions 3b and 3c that project in parallel to the opposite sides, and in a state where one linear end portion 3b and the start end of the cable hanger H are connected by an insertion meshing connection tool 4, Using the material elasticity, the overlapping portions of the winding ring portion 3a are expanded by separating both linear ends 3b and 3c, and a support line L is fitted into the ring portion 3a as shown in the figure from the gap. The leading end of the cable hanger H cannot be detached from the support line L by passing it through.

送り込み手段2は、図8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. 8 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。   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.

従って、本架設方法においては、まず送り出し装置1の送出ドラム12から繰り出した螺旋状ケーブルハンガーHの始端側を先導部材3を介して支持線Lの一端側に巻き絡ませた上で、該送り出し装置1を駆動させて該ケーブルハンガーHを連続的に送り出しながら、そのまま送り込み手段2によって支持線Lに沿って該ケーブルハンガーHを送り込んでゆけばよい。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。   Therefore, in this erection method, first, the starting end side of the spiral cable hanger H fed from the sending drum 12 of the sending device 1 is wound around one end side of the support line L via the leading member 3 and then the sending device. 1 is driven and the cable hanger H is continuously sent out while the cable hanger H is sent along the support line L by the feeding means 2 as it is. 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.

かくして支持線Lの他端側つまり電柱P2側の設定部位まで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。   Thus, the starting end of the cable hanger H that has reached the other end side of the support line L, that is, the set part on the utility pole P2 side, is fixed to the support line L or the utility pole P2 using an appropriate fixture, 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.

このような螺旋状ケーブルハンガーHの架設方法によれば、送り出し装置1の送出ドラム12に巻装された無連結長尺の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ができるから、従来汎用の短尺の螺旋状ケーブルハンガーのように高所でケーブルハンガー同士を順次接続してゆく煩雑な作業が不要になり、少ない労力によって容易に短時間で高能率の架設作業を行える。そして、架設後の該螺旋状ケーブルハンガーHは、全体が連続していて破損し易いコネクタ部分を有しないため、優れた耐久性を発揮するものとなる。また、螺旋状ケーブルハンガーH自体は、製造時の長尺のままで利用でき、従来のように短尺に分断してその各分断物の両端にコネクタを止着するのに比較し、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 such a construction method of the helical cable hanger H, the unconnected long helical cable hanger H wound around the delivery drum 12 of the delivery device 1 is continuously fed while being twisted and rotated in the spiral traveling direction. Since the support wire L can be entangled from one end side of the support wire L and sent to the other end side, the cable hangers are connected one after another at a high place like conventional general-purpose short helical cable hangers. Work becomes unnecessary, and high-efficiency erection work can be easily performed in a short time with little labor. And since this helical cable hanger H after construction does not have the connector part which the whole continues and is easy to break, it will show the outstanding durability. In addition, the helical cable hanger H itself can be used as it is at the time of manufacture, and compared to the conventional method of dividing into short pieces and attaching connectors to both ends of each piece, the material cost and There is an advantage that the processing cost can be greatly reduced.

一方、上記架設方法に用いる送り出し装置1は、架台10上に設けたドラム取付台11と、このドラム取付台11に枢支した送出ドラム12とが互いに垂直な回転軸(垂直枢軸13a,水平枢軸13b)を有し、回転駆動手段によってドラム取付台11を回転することにより、回転伝達手段14を介して送出ドラム12が連動回転する構造であるから、構成的に非常に簡素であって安価に製作できると共に、螺旋状ケーブルハンガーHを確実に螺旋進行方向に捩れ回転させながら安定的に送出できるという利点がある。   On the other hand, the delivery device 1 used in the above-described erection method has a rotating shaft (vertical pivot 13a, horizontal pivot) in which a drum mount 11 provided on the mount 10 and a feed drum 12 pivotally supported on the drum mount 11 are perpendicular to each other. 13b), and the drum mounting base 11 is rotated by the rotation driving means so that the delivery drum 12 rotates in conjunction with the rotation transmitting means 14. Therefore, the structure is very simple and inexpensive. There is an advantage that the helical cable hanger H can be stably delivered while being twisted and rotated in the spiral traveling direction with certainty.

なお、螺旋状ケーブルハンガーHの巻き束H0は、既述のように全長40〜60m程度に設定されるが、架設区間の長さが一定ではないために当然に長さの過不足を生じる。そこで、架設区間に対して巻き束H0の長さが不足する場合や、前に使用した時の余剰分を利用する場合には、図8に示すように、先に送り出される螺旋状ケーブルハンガーH1の終端に、既述した先導部材3の連結に用いたものと同様の差込み噛合式連結具4を利用して、新たな螺旋状ケーブルハンガーH2の始端を継ぎ足すことになる。   Note that the winding bundle H0 of the helical cable hanger H is set to a total length of about 40 to 60 m as described above, but naturally the length of the erection section is not constant, so that the length is naturally excessive or insufficient. Therefore, when the length of the winding bundle H0 is insufficient with respect to the erected section, or when using the surplus when used before, as shown in FIG. 8, the spiral cable hanger H1 sent out first is shown. The starting end of a new spiral cable hanger H2 is added to the end of the cable using the same insertion meshing connector 4 used for connecting the leading member 3 described above.

このような差込み噛合式連結具4は、図9に示すように、両端部に各々開口したハンガー挿入孔40aを有する合成樹脂製の筒状本体40、その各ハンガー挿入孔40aの内部に配置した弾性金属材からなる係止リング41、各ハンガー挿入孔40a内の入口側に嵌着した金属製の口金筒42、各口金筒42内の奥側に嵌装した金属製の押さえリング43、各口金筒42内の入口側に嵌装した合成樹脂製のロック解除筒44、各押さえリング43の内奥側に配置するゴム製のクッションリング45、より構成されている。   As shown in FIG. 9, such a plug-and-engage coupling tool 4 is disposed inside a synthetic resin cylindrical main body 40 having hanger insertion holes 40 a opened at both ends, and the respective hanger insertion holes 40 a. A locking ring 41 made of an elastic metal material, a metal cap cylinder 42 fitted on the inlet side in each hanger insertion hole 40a, a metal pressing ring 43 fitted on the back side in each cap cylinder 42, each It is composed of a synthetic resin unlocking cylinder 44 fitted on the inlet side in the cap cylinder 42 and a rubber cushion ring 45 arranged on the inner back side of each holding ring 43.

そして、筒状本体40は、両ハンガー挿入孔40a,40aの奥端間が径小孔部40bで連通しており、径小孔部40bによって各ハンガー挿入孔40aに対するケーブルハンガーH1,H2の挿入限界位置が定まっている。各係止リング41は、内周側に孔奥側へ傾斜して突出する複数の係止爪41a…を備え、これら係止爪41a…の先端を結ぶ内径が常態ではケーブルハンガーH1,H2の径よりも若干小さく設定されており、外周部において口金筒42内の奥側の環状段部40bと押さえリング43の外端との間で挟持されている。各口金筒42は、外端フランジ部42aがハンガー挿入孔40aから部分的に突出し、且つ軸方向中間部の外周に設けた環状凸部42dが筒状本体40側に食い込む状態で、該筒状本体40に固着している。   The tubular main body 40 is connected to the rear ends of both hanger insertion holes 40a, 40a by small-diameter hole portions 40b, and the cable hangers H1, H2 are inserted into the respective hanger insertion holes 40a by the small-diameter hole portions 40b. The limit position is fixed. Each locking ring 41 is provided with a plurality of locking claws 41a... Projecting obliquely toward the inner hole side on the inner peripheral side, and the inner diameters connecting the tips of the locking claws 41a are normally in the cable hangers H1 and H2. It is set to be slightly smaller than the diameter, and is sandwiched between the annular stepped portion 40 b on the inner side of the cap cylinder 42 and the outer end of the pressing ring 43 at the outer peripheral portion. Each base tube 42 has an outer end flange portion 42a partially protruding from the hanger insertion hole 40a, and an annular convex portion 42d provided on the outer periphery of the axial intermediate portion bites into the cylindrical main body 40 side. The main body 40 is fixed.

また、ロック解除筒44は、内径がケーブルハンガーH1,H2の径よりも僅かに大きく、外端フランジ部44aが口金筒42の外端フランジ部42aから外側へ離間した常態において、外周側が縮径するテーパー状内端部42bが係止リング41の係止爪41a…に当接すると共に、該テーパー状内端部42bの近傍の外周に設けた外向きの係止段部44cが口金筒42の外端側内周の係止段部42cに係合している。しかるに、外端フランジ部44aを押圧して全体を押し込めば、テーパー状内端部44aが係止リング41の係止爪41a…を傾斜度合を増すように弾性変形させることになる。   Further, the inner diameter of the unlocking cylinder 44 is slightly larger than the diameters of the cable hangers H1 and H2, and the outer peripheral side is reduced in diameter in the normal state in which the outer end flange portion 44a is spaced outward from the outer end flange portion 42a of the cap cylinder 42. The tapered inner end portion 42b contacts the locking claws 41a of the locking ring 41, and an outward locking step portion 44c provided on the outer periphery in the vicinity of the tapered inner end portion 42b It engages with a locking step 42c on the outer peripheral side inner periphery. However, when the outer end flange portion 44a is pressed and the whole is pushed in, the tapered inner end portion 44a elastically deforms the locking claws 41a of the locking ring 41 so as to increase the degree of inclination.

この差込み噛合式連結具4による継ぎ足し連結は、図9の右半部で代表して示すように、ケーブルハンガーH1,H2の端部をハンガー挿入孔40aの奥端まで挿入するだけでよい。この挿入操作により、係止リング41の係止爪41a…は強制的に押し広げられる形で各々の傾斜度合を増してケーブルハンガーH1,H2の挿通を許容するが、その孔奥側へ傾斜した各係止爪41aの先端が合成樹脂層Rの表面に食い付くため、挿入後のケーブルハンガーH1,H2は抜出方向へ移動不能なロック状態となり、もって強固な継ぎ足し連結を行える。一方、この連結状態からロック解除筒44を押し込めば、そのテーパー状内端部44aが係止リング41の係止爪41a…の先端側を内奥側へ押し出すから、これら係止爪41a…の合成樹脂層Rの表面への食い込みが外れてロック解除され、ケーブルハンガーH1,H2の端部がハンガー挿入孔40aから抜出可能となる。   As shown in the right half part of FIG. 9, the addition connection by the insertion engagement type connector 4 only needs to insert the end portions of the cable hangers H1 and H2 to the far end of the hanger insertion hole 40a. By this insertion operation, the locking claws 41a of the locking ring 41 are forcibly pushed and widened to increase the respective inclinations and allow the cable hangers H1 and H2 to be inserted. Since the tips of the respective locking claws 41a bite into the surface of the synthetic resin layer R, the cable hangers H1 and H2 after insertion are in a locked state where they cannot move in the extraction direction, and can be firmly connected. On the other hand, when the unlocking cylinder 44 is pushed in from this connected state, the tapered inner end 44a pushes the front end side of the locking claws 41a of the locking ring 41 inward, so that the locking claws 41a. The bite into the surface of the synthetic resin layer R is released and unlocked, and the ends of the cable hangers H1 and H2 can be extracted from the hanger insertion hole 40a.

螺旋状ケーブルハンガーHとしては、特に制約されないが、亜鉛メッキ鋼線等よりなる金属芯線Mがフッ素系樹脂を含む合成樹脂層Rで被覆されたものが推奨される。これは、合成樹脂層Rがフッ素系樹脂を含むことで良好な表面滑性を示すため、該ケーブルハンガーHを支持線Lに沿って送り出す際の摩擦抵抗が少なくなり、それだけ送り込みが容易になることによる。上記フッ素系樹脂としては、特に制約されないが、PTFE(ポリテトラフルオロエチレン)の粉粒体が好適である。また、合成樹脂層Rのベース樹脂としては、従来よりケーブルハンガーの被覆層に採用されているポリエチレンやポリエチレンテレフタレート等の一般的な熱可塑性樹脂が好ましい。   The spiral cable hanger H is not particularly limited, but one in which a metal core wire M made of galvanized steel wire or the like is covered with a synthetic resin layer R containing a fluorine-based resin is recommended. This is because the synthetic resin layer R contains a fluorine-based resin and exhibits good surface lubricity, so that the frictional resistance when the cable hanger H is sent out along the support line L is reduced, and the feeding becomes easier. It depends. Although it does not restrict | limit especially as said fluororesin, The granular material of PTFE (polytetrafluoroethylene) is suitable. The base resin of the synthetic resin layer R is preferably a general thermoplastic resin such as polyethylene or polyethylene terephthalate which has been conventionally used for a cable hanger covering layer.

なお、既述したケーブルハンガーH1,H2の継ぎ足し連結を行う際、その合成樹脂層Rが上記フッ素系樹脂を含むような低摩擦材料である場合、一般的なかしめ式の連結具では表面での滑りによって抜け易いが、例示した差込み噛合式の連結具4では係止爪41a…が合成樹脂層Rに食い込むことで確実に抜出防止できる。ただし、このような差込み噛合式の連結具4としては、係止爪41aの止着構造やロック解除機構が例示とは種々異なるものも採用可能である。   When the above-described cable hangers H1 and H2 are added and connected, if the synthetic resin layer R is a low-friction material containing the fluororesin, a general caulking-type connector is used on the surface. Although it is easy to come off by slipping, in the illustrated engagement type connector 4, the locking claws 41 a... Bite into the synthetic resin layer R and can be reliably prevented from being pulled out. However, as such an insertion-engagement type connecting tool 4, it is also possible to adopt various ones in which the fastening structure of the locking claw 41a and the unlocking mechanism are different from those illustrated.

支持線Lは、例示した実施形態で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を地上に設置しているが、これ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 in the illustrated embodiment, 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. Furthermore, in the figure, the feeding device 1 for the cable hanger H is installed on the ground, but it is also possible to work by loading it on a gondola of an aerial work vehicle.

送り出し装置1の回転駆動手段としては、電動モーター等の機械的動力を利用するものも採用可能であるが、実施形態として例示したように手動回転ハンドル15の回転力をドラム取付台11の回転軸(垂直枢軸13a)に伝えるものとすれば、各別な機械的動力を要さずに人力のみで駆動操作できるから、例えば山間部等で電源の確保が困難な場所でも支障なく架設作業を行えるという利点がある。また、回転伝達手段14についても、様々な伝達機構を採用できるが、実施形態のように、ドラム取付台11と一体に回転する駆動側傘歯歯車14aに、送出ドラム12の回転軸(水平枢軸13b)と平行な回転軸14cに固着された従動側傘歯歯車14bが噛合し、この従動側傘歯歯車14bの回転軸14cの回転を送出ドラム12の回転軸(水平枢軸13b)に伝えるものとすれば、機構的に簡素で作動の信頼性に優れるという利点がある。   As the rotation drive means of the delivery device 1, a device using mechanical power such as an electric motor can be adopted. However, as exemplified in the embodiment, the rotational force of the manual rotation handle 15 is used to rotate the rotation shaft of the drum mounting base 11. If it is transmitted to the (vertical pivot 13a), it can be driven and operated by human power without requiring separate mechanical power. For example, installation work can be performed without trouble even in places where it is difficult to secure a power source in a mountainous area or the like. There is an advantage. Various transmission mechanisms can also be adopted for the rotation transmission means 14, but as in the embodiment, the rotation shaft (horizontal pivot) of the delivery drum 12 is connected to the drive side bevel gear 14 a that rotates integrally with the drum mount 11. A driven bevel gear 14b fixed to a rotating shaft 14c parallel to 13b) meshes with the rotating shaft 14c of the driven bevel gear 14b and transmits the rotation of the rotating shaft 14c to the rotating shaft (horizontal pivot 13b) of the delivery drum 12. If so, there is an advantage that the mechanism is simple and the operation reliability is excellent.

送り込み手段2としては、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。しかるに、作業能率面では劣るが、このような送り込み手段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。   As the feeding means 2, various feeding mechanisms can be adopted other than the combination of the illustrated roller tool 20 and the electric rotary tool 21. However, although it is inferior in terms of work efficiency, the spiral cable hanger H can be manually fed without using such a feeding means 2.

また、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、例示した巻きリング部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。その他、本発明の架設方法及び送り出し装置の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。   Moreover, as the leading member 3 of the helical cable hanger H, it is only necessary to have a function of preventing separation from the support line L, and various forms can be adopted, but the winding ring portion 3a illustrated is included. In the form, there is an advantage that it can be easily manufactured at low cost by bending the same wire as the cable hanger H. In addition, the detailed configuration of the erection method and the delivery device of the present invention can be variously modified in addition to the embodiment.
