Description
本発明は、送電線鉄塔に備えられている送電線がいし装置の保守作業を行う際に用いる溶剤、シリコン樹脂等の液体の落滴を防止する送電線がいし装置における落滴防止装置に関する。 The present invention relates to a drop-preventing device in a transmission-line insulator device that prevents a liquid, such as a solvent or a silicone resin, from dropping when a transmission-line insulator device provided in a transmission-line tower is maintained.
送電線に使用されているがいし装置について、その表面が汚損されないように定期的に保守作業を行っている。がいし装置は、その表面が汚損されると、絶縁性が低下し、耐電圧特性が低下する。そこで、塩塵による送電線がいし装置のコロナ対策として、シリコン樹脂塗布を実施している。しかし、がいし装置は風雨にさらされるとシリコン樹脂が剥離し、その効果が低下する。そこで、数年に１度シリコン樹脂の塗り替え作業などの保守作業を実施している。 For insulators used in power transmission lines, maintenance work is regularly performed so that the surface is not soiled. When the surface of the insulator device is soiled, the insulating property is lowered and the withstand voltage characteristic is lowered. Therefore, silicon resin coating is implemented as a countermeasure against corona in power transmission insulators using salt dust. However, when the insulator device is exposed to wind and rain, the silicon resin is peeled off and the effect is reduced. Therefore, maintenance work such as repainting of silicon resin is performed once every several years.
がいし装置のシリコン樹脂の塗り替え作業を実施する際には、送電線鉄塔上において、がいし装置の表面に塗布した古くなったシリコン樹脂をアルコール系の溶剤を浸み込ませたウエス等で剥ぎ取り、その後シリコン樹脂を塗布している。これらの除去と塗布の作業に際して、溶剤やシリコン樹脂が送電線鉄塔付近の民家等に落滴しないように注意して実施する。 When carrying out the repainting operation of the silicon resin of the insulator device, on the transmission line tower, peel off the old silicon resin applied to the surface of the insulator device with a cloth soaked with an alcohol solvent, etc. Thereafter, silicon resin is applied. When removing and applying these components, care should be taken so that the solvent and silicon resin do not drop onto private houses near the transmission line tower.
このような溶剤やシリコン樹脂が落滴しないように作業をするための技術に関しては種々提案されている。例えば特許文献１の特開平１１−３００４１号公報「防護養生シート体」に示すように、鉄塔本体上部に水平方向に延びるアームを備える鉄塔で高所作業する際、アームを養生する仮設の防護養生シート体であって、アームを挟んで対向する２面のシートと、２面のシートをそれぞれ懸架させる２個の懸架フレームとを備え、各懸架フレームは、基端で鉄塔本体に着脱自在に連結され、水平又は斜め下方にかつアームと同じ方位に少なくともアームの先端より先方まで延在する支持部材と、支持部材の基端より高い位置で鉄塔本体に着脱自在に連結され、斜め下方に延びて、支持部材の中間で支持部材を吊って支持する上部斜方吊り部材と、支持部材の基端より低い位置で鉄塔本体に着脱自在に連結され、斜め上方に延びて支持部材の中間で支持部材を支持する下部斜支柱部材の少なくとも一方を有し、各シートは、上縁部で懸架フレームの支持部材に連結され、上縁部より懸架して下縁部でアームより下方に延在し、かつシートの外縁部のうちの少なくとも下縁部に２面のシート同士を相互に連結する連結具を備えている防護養生シート体が提案されている。 Various techniques for working such that the solvent and silicon resin do not drop have been proposed. For example, as shown in Japanese Patent Application Laid-Open No. 11-30041 “Protective Curing Sheet Body” of Patent Document 1, a temporary protective curing for curing an arm when working at a high position on a steel tower having an arm extending horizontally in the upper part of the steel tower body. A sheet body, comprising two sheets facing each other across an arm, and two suspension frames for suspending the two sheets respectively, and each suspension frame is detachably connected to the tower main body at the base end A support member that extends horizontally or obliquely downward and at least in front of the tip of the arm in the same orientation as the arm, and is detachably connected to the tower body at a position higher than the base end of the support member, and extends obliquely downward. An upper oblique suspension member that suspends and supports the support member in the middle of the support member, and is detachably connected to the tower body at a position lower than the base end of the support member, and extends obliquely upward and in the middle of the support member At least one of the lower slant support members that support the holding member is provided, and each seat is connected to the support member of the suspension frame at the upper edge, and is suspended from the upper edge and extends below the arm at the lower edge. And the protective curing sheet body provided with the connection tool which connects two sheets mutually to the at least lower edge part of the outer edge part of a sheet | seat is proposed.
また、特許文献２の特開２００８−２５９９３７号公報「がいし装置への塗料等付着防止カバー及びその付着防止方法」に示すように、鉄塔に架設する電線を絶縁しながら支持するがいし装置のがいし部分を覆い、該鉄塔の塗装処理を行う際に、該がいし部分へ塗料等が付着することを防止するがいし装置への塗料等付着防止カバーであって、前記がいし装置のライン側アーキングホーンに掛け止める掛止め具を、先端に具備した操作棒と、塗料等の付着を防止するために、前記がいし部分に巻き付ける程度の面積を有し、かつ可撓性を有する略四角形状の保護シート材と、から成り、前記保護シート材の一辺両端は、前記操作棒の両先端に固定し、該保護シート材の両側縁に取り付けた複数の挿通リングをそれぞれ各操作棒に挿通させることにより、該保護シート材を前記がいし部分の長さに調節して該がいし部分に巻き付け得るように構成したがいし装置への塗料等付着防止カバーが提案されている。 In addition, as shown in Japanese Patent Application Laid-Open No. 2008-259937, “Paint prevention cover for paints and the like, and method for preventing the adhesion thereof”, the insulator portion of the insulator device that supports the wires installed on the steel tower while insulating them. A cover for preventing the paint from adhering to the insulator part when the steel tower is painted, and preventing the paint from adhering to the insulator device, which is hung on the line side arcing horn of the insulator device. An operation rod provided at the tip of the latching tool, and a substantially rectangular protective sheet material having an area enough to be wound around the insulator portion in order to prevent adhesion of paint or the like, and having flexibility, The protective sheet material is fixed to both ends of the operation rod, and a plurality of insertion rings attached to both side edges of the protection sheet material are inserted into the operation rods. Accordingly, we paint adhesion preventing cover of the protective sheet material is adjusted to the length of the insulators portion to the configuration was but insulator device such that the can wound around the stone portion has been proposed.
一般に送電線がいし装置のシリコン樹脂の塗布、除去は、比較的短時間での作業であり、１日で複数の鉄塔へ移動して作業するため、軽量かつコンパクトな落滴防止装置であることが望ましい。しかし、特許文献１の「防護養生シート体」では、多数の部品からなり、その運搬、鉄塔上への荷揚げ・荷下ろし、組立て・解体といった作業工程が増え作業の安全性が低下しやすく、作業時間・労力を要するために作業コスト面で実用的ではないという問題は有していた。 In general, the application and removal of silicon resin in a transmission line insulator device is a relatively short work, and since it moves to a plurality of steel towers in one day, it is a lightweight and compact drop prevention device. desirable. However, the “protective curing sheet” of Patent Document 1 is composed of a large number of parts, and the work processes such as transportation, unloading and unloading on the steel tower, assembling and dismantling increase, and the safety of the work tends to decrease. Since time and labor were required, there was a problem that it was not practical in terms of work cost.
また、特許文献２の「がいし装置への塗料等付着防止カバー及びその付着防止方法」では、保護シート材をがいし装置の上部から覆い塗料等が付着することを防止する構成である。がいし装置のシリコン樹脂の塗布、除去作業のように、落滴を防止するためにはがいし装置下部へ袋状に設置すること、作業空間を確保のために付帯装置を設置する必要があり、このままシリコン樹脂溶剤等の落滴防止装置には流用しづらいという問題は有していた。 Further, “Paint prevention adhesion cover and the like prevention method to the insulator device” of Patent Document 2 is configured to cover the protective sheet material from the upper part of the insulator device and prevent adhesion of the paint or the like. In order to prevent dropping, as in the case of applying and removing silicon resin from the insulator, it is necessary to install it in a bag shape at the bottom of the insulator, and to install an accessory device to secure the work space. There has been a problem that it is difficult to divert to a dripping prevention device such as a silicon resin solvent.
本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、装置全体を伸縮可能な構造にすることで、がいし装置（がいし連）の長さに応じて伸縮した形状を自立して保持でき、養生の準備を短時間で終了させ、かつシリコン樹脂、塗料、溶剤等の落滴を防止できると共に、作業終了後に装置をコンパクトに折り畳むことができ、山間部などへ容易に運搬することができる送電線がいし装置における落滴防止装置を提供することにある。 The present invention has been developed to solve such problems. That is, the object of the present invention is to make the entire device extendable and contractible so that the shape that expands and contracts according to the length of the insulator device can be held independently, and the preparation for curing is completed in a short time. In addition, it is possible to prevent dripping of silicon resin, paint, solvent, etc., and the device can be folded compactly after the work is finished, and the dripping prevention device in the transmission line insulator device that can be easily transported to mountainous areas etc. Is to provide.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a dripping prevention device in power transmission work of the present invention. 2A and 2B show a drop-preventing device according to the first embodiment, where FIG. 2A is a partially omitted plan view, and FIG. 2B is a partially omitted front view.
The drop-preventing device 1 of the first embodiment can be expanded to a length substantially the same as the longitudinal direction of the insulator device i and can be folded, and a silicon resin, a solvent, a paint, etc. that drops from the insulator device i. And a drip-proof bag 3 for receiving the liquid. The drop-preventing bag 3 has the same size as the width when the frame member 2 is fully developed. The drop prevention device 1 of the present invention attaches the opening edge 4 of the drop prevention bag 3 to the frame member 2, and changes the width of the drop prevention bag 3 to be developed by following the expansion or folding of the frame member 2. It has come to be able to do.
〈短辺枠部材〉
枠材２は、短辺方向の両側に２本の短辺枠部材５と、各短辺枠部材５の両端に、複数本の連結部材６を連結した２組の長辺枠部材７をそれぞれ連結して長方形状にしたものである。例えば短辺枠部材５は、２５〜３０ｃｍの長さを有するパイプ状のアルミ製の部材である。容易に運搬できるように軽量な金属製の部材が好ましい。または剛性を有する合成樹脂製の素材を用いることも可能である。
<Short side frame member>
The frame member 2 includes two short-side frame members 5 on both sides in the short-side direction, and two sets of long-side frame members 7 each having a plurality of connecting members 6 connected to both ends of each short-side frame member 5. It is connected to form a rectangle. For example, the short side frame member 5 is a pipe-shaped aluminum member having a length of 25 to 30 cm. A lightweight metal member is preferred so that it can be easily transported. Alternatively, a synthetic resin material having rigidity can be used.
〈コーナー用角度調節板〉
図３は短辺枠部材のコーナー用角度調節板を示し、（ａ）は平面図、（ｂ）は正断面図である。
短辺枠部材５には、１本の棒状の部材両端に長辺枠部材７を構成する連結部材６を連結すると共にその角度を規制するコーナー用角度調節板８を取り付けた。このコーナー用角度調節板８は、扇形状の板部材からなり、その扇形状の「要（かなめ）」に相当する位置に連結孔９を開け、連結部材６の端部を軸部材１０で回動自在に連結してある。コーナー用角度調節板８には、円弧形状に沿って数箇所の係合凹部１１をそれぞれ設けた。正確には連結孔９を回転の中心点として等距離かつ等角度ごとに数箇所の係合凹部１１を設けた。
例えば、このコーナー用角度調節板８は、９０度の角度を有する円弧形状の金属製の板材である。なお、この９０度の角度には限定されない。これより少し広い角度になってもよい。また、係合凹部１１は後述するボール１２が止まれば良いので、コーナー用角度調節板８が薄い部材のときは貫通孔にしても良い（図示していない。）。
<Corner angle adjustment plate>
FIG. 3 shows a corner angle adjusting plate of the short side frame member, where (a) is a plan view and (b) is a front sectional view.
The short side frame member 5 is provided with a corner angle adjusting plate 8 for connecting the connecting member 6 constituting the long side frame member 7 to both ends of one rod-like member and regulating the angle thereof. The corner angle adjusting plate 8 is made of a fan-shaped plate member. A connecting hole 9 is opened at a position corresponding to the fan-shaped “kaname”, and the end of the connecting member 6 is rotated by the shaft member 10. It is connected freely. The corner angle adjusting plate 8 is provided with several engaging recesses 11 along an arc shape. More precisely, several engaging recesses 11 are provided at equal distances and at equal angles with the connecting hole 9 as the center point of rotation.
For example, the corner angle adjusting plate 8 is an arc-shaped metal plate having an angle of 90 degrees. The angle is not limited to 90 degrees. The angle may be a little wider than this. Further, the engaging recess 11 may be a through-hole (not shown) when the angle adjusting plate 8 for the corner is a thin member since the ball 12 described later is stopped.
このコーナー用角度調節板８は、図２（ａ）に示したように、短辺枠部材５の両端に、コーナー用角度調節板８の円弧形状部分が向かい合うと共に、直線の一辺が短辺枠部材５の直線方向と平行になるように固定する。これは、がいし装置ｉの横幅の長さは極端に変わることがないので、一定の長さにすることができる。また、短辺枠部材５に固定することにより、後述するように長辺枠部材７の角度調整が容易になるからである。 As shown in FIG. 2A, the corner angle adjusting plate 8 has the arc-shaped portion of the corner angle adjusting plate 8 facing both ends of the short side frame member 5, and one side of the straight line is a short side frame. The member 5 is fixed so as to be parallel to the linear direction. This is because the length of the lateral width of the insulator device i does not change drastically, and can be made constant. Moreover, it is because the angle adjustment of the long side frame member 7 becomes easy by fixing to the short side frame member 5 so that it may mention later.
コーナー用角度調節板８の連結孔９に、長辺枠部材７の各連結部材６の一端を回動可能に取り付ける。このように連結部材６を折り畳み可能にして、落滴防止袋３の面積を調整する。 One end of each connecting member 6 of the long side frame member 7 is rotatably attached to the connecting hole 9 of the corner angle adjusting plate 8. In this way, the connecting member 6 can be folded, and the area of the drop-preventing bag 3 is adjusted.
〈連結部材とコーナー用角度調節板との係合状態〉
コーナー用角度調節板８は、枠材２を構成する連結部材６の折り畳みの角度を規制するものである。そこで、連結部材６には、図３（ｂ）の断面図に示すように、各係合凹部１１に嵌脱するボール１２が設けられている。例えば、連結部材６の係合部１３は、この連結部材６の軸方向と直交する方向へ向けて開けたボール穴１４内に例えばコイルばねのようなばね１５とボール１２を順番に収納したものである。このばね１５の弾性力でボール１２を出没自在に連結部材６の外周側へ押圧するように構成した。ボール穴１４の開口部はばね１５が外れないように、ボール１２の外径より短い内径を有する。これらのボール１２、ばね１５は例えばステンレス等の酸化しない材料が適している。
<Engagement of connecting member and corner angle adjustment plate>
The corner angle adjusting plate 8 regulates the folding angle of the connecting member 6 constituting the frame member 2. Therefore, as shown in the cross-sectional view of FIG. For example, the engaging portion 13 of the connecting member 6 is one in which a spring 15 such as a coil spring and a ball 12 are sequentially accommodated in a ball hole 14 opened in a direction perpendicular to the axial direction of the connecting member 6. It is. The ball 12 is configured to be pushed and retracted by the elastic force of the spring 15 to the outer peripheral side of the connecting member 6. The opening of the ball hole 14 has an inner diameter shorter than the outer diameter of the ball 12 so that the spring 15 does not come off. These balls 12 and springs 15 are suitably made of a non-oxidizing material such as stainless steel.
連結部材６がコーナー用角度調節板８に係合する状態、即ち角度調節する方法を説明する。
先ず、連結部材６をコーナー用角度調節板８の「要（かなめ）」点（連結孔９）を中心点にして回動する。このとき係合部１３のボール１２は、ばね１５によりボール穴１４内に沈み、連結部材６をコーナー用角度調節板８において回動させることができる。
A state in which the connecting member 6 is engaged with the corner angle adjusting plate 8, that is, a method for adjusting the angle will be described.
First, the connecting member 6 is turned around the “required” point (connecting hole 9) of the corner angle adjusting plate 8. At this time, the ball 12 of the engaging portion 13 sinks into the ball hole 14 by the spring 15, and the connecting member 6 can be rotated on the corner angle adjusting plate 8.
連結部材６をある程度回動させると、係合部１３のボール１２が係合凹部１１に到達し、このボール１２はばね１５により浮き上がり（図示例では下方へ飛び出し）、係合凹部１１内に係合して抜け止めとしての機能を果たす。これにより、コーナー用角度調節板８の所望の係合凹部１１の位置で固定することができる。更に別の角度に曲げたいときは、同様な動作を繰り返すことにより、コーナー用角度調節板８に対する連結部材６の角度を可変することができる。 When the connecting member 6 is rotated to some extent, the ball 12 of the engaging portion 13 reaches the engaging recess 11, and the ball 12 is lifted by the spring 15 (jumps downward in the illustrated example) and is engaged in the engaging recess 11. Combined, it functions as a stopper. Thereby, it can fix in the position of the desired engagement recessed part 11 of the angle adjustment board 8 for corners. When it is desired to bend to another angle, the angle of the connecting member 6 with respect to the corner angle adjusting plate 8 can be varied by repeating the same operation.
〈連結部材とコーナー用角度調節板との係合状態の変形例〉
連結部材６の係合部１３は、図３（ｂ）の断面図に示したボール１２とばね１５を内装したボール穴１４の構成に限定されない。例えば、ボール１２に代えて、連結部材６内に溝を軸方向に形成し、この溝内に先端が球体を成す位置決め用突起部を出没自在に収納した構成でもよい（図示していない）。この位置決め用突起部は、溝内において連結部材６の溝内に回動軸で出没自在に軸止すると共に、この位置決め用突起部を連結部材６の周囲外方向へ押し出すようにコイルスプリング、板ばね等の弾性部材をその位置決め用突起部間に介在する。この位置決め用突起部は、連結部材６の外周より突出させ、また溝内に押し込むことができる。位置決め用突起部は、弾性部材の押圧力で突出したときは、位置決め用突起部がコーナー用角度調節板８の所望の係合凹部１１に引っ掛かるようすることも可能である。
<Modified example of engagement state between connecting member and corner angle adjusting plate>
The engaging portion 13 of the connecting member 6 is not limited to the configuration of the ball hole 14 in which the ball 12 and the spring 15 are housed as shown in the cross-sectional view of FIG. For example, instead of the ball 12, a groove may be formed in the connecting member 6 in the axial direction, and a positioning protrusion whose tip may be a sphere may be housed in the groove so as to be retractable (not shown). The positioning projection is fixed in a groove of the connecting member 6 in the groove so as to be able to protrude and retract with a rotating shaft, and the positioning protrusion is pushed out of the periphery of the connecting member 6 with a coil spring and a plate. An elastic member such as a spring is interposed between the positioning projections. This positioning projection can protrude from the outer periphery of the connecting member 6 and can be pushed into the groove. When the positioning projection protrudes with the pressing force of the elastic member, the positioning projection can be hooked on the desired engagement recess 11 of the corner angle adjusting plate 8.
短辺枠部材５には、図１に示したように、落滴防止袋３の開口縁４以外に、吊り下げ具１６を掛け止めるひも状部材１７をそれぞれ取り付けた。吊り下げ具１６は、がいし装置ｉ、架線Ｃ、鉄塔腕金又は鉄塔Ｔに掛け止めることにより、本発明の落滴防止装置１を吊り下げる。 As shown in FIG. 1, in addition to the opening edge 4 of the drop-preventing bag 3, a string-like member 17 that holds the hanging tool 16 is attached to each short side frame member 5. The hanging tool 16 hangs the dripping prevention device 1 of the present invention by hanging on the insulator device i, the overhead line C, the steel tower arm or the steel tower T.
〈コーナー用角度調節板の過回動防止ストッパ〉
短辺枠部材５のコーナー用角度調節板８の外端縁に、長辺枠部材７を構成する連結部材６が、コーナー用角度調節板８から外れて過回動することを防止するストッパ１８を設けることが好ましい。例えば、過回動防止ストッパ１８はコーナー用角度調節板８の連結部材６を連結した直線辺に舌片をこの連結部材６が連結されている側に立ち上げたものである。
または、図示していないが、コーナー用角度調節板８の直線辺の一部に突起を設け、この突起に当接する突起を連結部材６側に設けたものでも良い。
<Anti-rotation stopper for corner angle adjustment plate>
A stopper 18 that prevents the connecting member 6 constituting the long side frame member 7 from coming off the corner angle adjusting plate 8 and over-rotating at the outer edge of the corner angle adjusting plate 8 of the short side frame member 5. Is preferably provided. For example, the over-rotation preventing stopper 18 is formed by raising a tongue piece on the side where the connecting member 6 is connected to a straight side connecting the connecting member 6 of the corner angle adjusting plate 8.
Alternatively, although not shown, a protrusion may be provided on a part of the straight side of the corner angle adjusting plate 8 and a protrusion that contacts the protrusion may be provided on the connecting member 6 side.
〈長辺枠部材〉
図４は長辺枠部材の中間用角度調節板を示し、（ａ）は平面図、（ｂ）は正断面図である。
枠材２を構成する長辺枠部材７は、図４に示すように、複数本の連結部材６を軸部材１０で連結したものである。各連結部材６は軸部材１０部分で折り曲げ自在になる。連結部材６は、例えば１０〜１５ｃｍの長さを有するパイプ状のアルミ製の部材である。運搬が容易になるように軽量な金属製の部材が好ましい。あるいは、剛性を有する合成樹脂製の素材を用いることも可能である。連結部材６の連結個数の多少により枠材２の長さが決まる。
<Long-side frame member>
FIG. 4 shows an intermediate angle adjusting plate for the long side frame member, where (a) is a plan view and (b) is a front sectional view.
As shown in FIG. 4, the long side frame member 7 constituting the frame member 2 is formed by connecting a plurality of connecting members 6 with a shaft member 10. Each connecting member 6 can be bent at the shaft member 10 portion. The connecting member 6 is a pipe-shaped aluminum member having a length of 10 to 15 cm, for example. A lightweight metal member is preferable so as to facilitate transportation. Alternatively, a synthetic resin material having rigidity can be used. The length of the frame member 2 is determined depending on the number of connected members 6.
〈中間用角度調節板〉
中間用角度調節板１９は、連結部材６の連結部に、一箇所置きに介在する。中間用角度調節板１９は、半円形状の板材であり、扇の「要（かなめ）」に相当する位置に連結孔２０を開け、ここで各連結部材６の端部を軸部材１０で回動自在に連結する。中間用角度調節板１９は、コーナー用角度調節板８と略同様に円弧形状に沿って数箇所の係合凹部１１をそれぞれ設けた。正確には連結孔２０を回動の中心点として等距離かつ等角度ごとに数箇所の係合凹部１１を設けた。
<Intermediate angle adjustment plate>
The intermediate angle adjusting plate 19 is interposed at every other place in the connecting portion of the connecting member 6. The intermediate angle adjusting plate 19 is a semi-circular plate material, and a connecting hole 20 is opened at a position corresponding to the “key” of the fan. Here, the end of each connecting member 6 is rotated by the shaft member 10. Connect freely. The intermediate angle adjusting plate 19 is provided with several engaging recesses 11 along the arc shape in substantially the same manner as the corner angle adjusting plate 8. To be precise, the engagement recesses 11 are provided at several positions at equal distances and at equal angles with the connection hole 20 as a center point of rotation.
中間用角度調節板１９の係合凹部１１に、上述した連結部材６の係合部１３のボール１２を係合させる。即ち連結部材６をある程度回動させると、係合部１３のボール１２が中間用角度調節板１９の係合凹部１１に到達し、このボール１２はばね１５により浮き上がり（図示例では下方へ飛び出し）、係合凹部１１内に係合して抜け止めとしての機能を果たす。これにより、中間用角度調節板１９の所望の係合凹部１１の位置で固定することができる。１枚の中間用角度調節板１９で２本の連結部材６の角度を規制することができる。
このように、中間用角度調節板１９で複数本の連結部材６を連結した長辺枠部材７は、連結部材６を折り畳み可能にして、落滴防止袋３の面積を調整する。
The ball 12 of the engaging portion 13 of the connecting member 6 described above is engaged with the engaging recess 11 of the intermediate angle adjusting plate 19. That is, when the connecting member 6 is rotated to some extent, the ball 12 of the engaging portion 13 reaches the engaging concave portion 11 of the intermediate angle adjusting plate 19, and the ball 12 is lifted by the spring 15 (jumps downward in the illustrated example). , Engages in the engaging recess 11 and functions as a retaining stopper. Thereby, it can fix in the position of the desired engagement recessed part 11 of the angle adjustment board 19 for intermediate | middle. The angle of the two connecting members 6 can be regulated by the single intermediate angle adjusting plate 19.
In this way, the long side frame member 7 in which the plurality of connecting members 6 are connected by the intermediate angle adjusting plate 19 enables the connecting member 6 to be folded and adjusts the area of the drop-preventing bag 3.
〈中間用角度調節板の過回動防止ストッパ〉
長辺枠部材７の中間用角度調節板１９の外端縁に、長辺枠部材７の連結部材６が、中間用角度調節板１９から外れて過回動することを防止するストッパ１８を設けた。中間用角度調節板１９の連結部材６を連結した直線辺に、２箇所に舌片をこの連結部材６が連結されている側に立ち上げたものである。または、中間用角度調節板１９の直線辺の一部に突起を設け、この突起に当接する突起を連結部材６側に設けたものでも良い（図示していない）。
<Anti-rotation stopper for intermediate angle adjustment plate>
A stopper 18 is provided at the outer edge of the intermediate angle adjusting plate 19 of the long side frame member 7 to prevent the connecting member 6 of the long side frame member 7 from coming off from the intermediate angle adjusting plate 19 and over-rotating. It was. On the straight side where the connecting member 6 of the intermediate angle adjusting plate 19 is connected, tongue pieces are raised at two locations on the side where the connecting member 6 is connected. Alternatively, a protrusion may be provided on a part of the straight side of the intermediate angle adjusting plate 19 and a protrusion that contacts the protrusion may be provided on the connecting member 6 side (not shown).
〈落滴防止袋〉
この短辺枠部材５と、長辺枠部材７を構成するこれらの連結部材６に、落滴防止袋３の開口縁４を取り付ける。落滴防止袋３の開口縁４の複数箇所に紐状の部材又はベルト状の部材を取り付け、これらを短辺枠部材５と、長辺枠部材７（連結部材６）に連結して吊り下げるようにする。
<Drip prevention bag>
The opening edge 4 of the drop-preventing bag 3 is attached to the short side frame member 5 and the connecting members 6 constituting the long side frame member 7. A string-like member or a belt-like member is attached to a plurality of locations on the opening edge 4 of the drop-preventing bag 3, and these are connected to the short-side frame member 5 and the long-side frame member 7 (connecting member 6) and suspended. Like that.
落滴防止袋３は、枠材２を最大限に拡げたときと同じ広さを有する長方形状の底部と、この底部の周囲から立ち上げるように周縁部とを形成した上方が開放された箱状のものである、その素材としては、フレキシブルな素材が好ましい。枠材２の折り畳みに追従して変形する必要があるからである。例えば、ポリエステル等の合成樹脂製シート、布製シートなどが好ましい。但し、がいし装置ｉのシリコン樹脂の塗り替え作業を実施する際に、シリコン樹脂を剥ぎ取るときに、アルコール系の溶剤を浸み込ませたウエス等を用いるので、これらの溶剤で損傷を受けない程度の耐久性は要求される。
落滴防止袋３の周縁部には、図１、図２に示したように、長辺枠部材７の連結部材６の連結部分と中間用角度調節板１９の連結部分での折れ曲がりに追従しやすいように、折り目２１を付けておく。この折り目２１を付けておくことで、使用しないときに、コンパクトに畳めるようになる。更に、落滴防止袋３の強度を高めるために補強番線２２を入れる。
The drop-prevention bag 3 is a box with an open top formed with a rectangular bottom having the same width as when the frame member 2 is expanded to the maximum and a peripheral edge so as to rise from the periphery of the bottom. The material is preferably a flexible material. This is because it is necessary to deform following the folding of the frame member 2. For example, a synthetic resin sheet such as polyester, a cloth sheet, and the like are preferable. However, when carrying out the repainting operation of the silicon resin of the insulator device i, when the silicon resin is peeled off, since a waste soaked with an alcohol solvent is used, it is not damaged by these solvents. Durability is required.
As shown in FIGS. 1 and 2, the drop prevention bag 3 follows the bend at the connecting portion of the connecting member 6 of the long side frame member 7 and the connecting portion of the intermediate angle adjusting plate 19 as shown in FIGS. A crease 21 is provided for easy processing. By attaching this crease 21, it can be folded compactly when not in use. Further, in order to increase the strength of the drop-preventing bag 3, a reinforcing wire 22 is inserted.
〈装着状態〉
図５は落滴防止装置を鉄塔とがいし装置に装着した状態を示す斜視図である。
このように構成した落滴防止装置１は、枠材２と共に落滴防止袋３を、がいし装置ｉの下方の全域に拡げ、吊り下げ具１６を鉄塔Ｔ、腕金又はがいし装置ｉ、架線Ｃに掛け止めて吊り下げる。この状態でがいし装置ｉの保守作業を行う。この保守作業に際して飛散する、溶剤、シリコン樹脂、塗料の落滴を始め、更には工具などの様々なものを落滴防止袋３で受け止めることができる。図示例では、作業用の梯子Ｌを送電線（架線）Ｃと鉄塔Ｔに掛け止めている。
<Worn state>
FIG. 5 is a perspective view showing a state in which the drop-preventing device is mounted on a steel tower and insulator device.
The drop-preventing device 1 configured as described above extends the drop-preventing bag 3 together with the frame material 2 to the entire area below the insulator device i, and the hanging tool 16 is a tower T, a brace or insulator device i, and an overhead wire C. Suspend and hang on. In this state, maintenance work of the insulator device i is performed. Various drops such as tools, droplets of solvent, silicon resin, and paint that are scattered during the maintenance work can be received by the drop prevention bag 3. In the illustrated example, a working ladder L is hung on a transmission line (overhead line) C and a steel tower T.
落滴防止装置１は、短いがいし装置ｉに対しては、図５に示すように、枠材２を折り曲げて落滴防止袋３と共に落滴防止装置１の全長を短くすることにより、架線Ｃと鉄塔Ｔ又は腕金の間が狭い場合にも、この落滴防止装置１安全に吊り下げることができる。逆に、長いがいし装置ｉに対しては、枠材２と落滴防止袋３を最大に展開して落滴防止装置１の全長を長くすることにより、広い範囲での落滴を防止することができる。 As shown in FIG. 5, the dripping prevention device 1, as shown in FIG. 5, bends the frame member 2 to shorten the overall length of the dripping prevention device 1 together with the dripping prevention bag 3. Even when the space between the steel tower T and the metal brace is narrow, the dripping prevention device 1 can be safely suspended. Conversely, for long insulator devices i, the frame material 2 and the drop-preventing bag 3 are deployed to the maximum to lengthen the overall length of the drop-preventing device 1, thereby preventing drops in a wide range. Can do.
また、この落滴防止装置１は、鉄塔Ｔの上部において数箇所で掛け止める構成であるために、作業者自身がこの落滴防止装置１を保持している必要がない。即ち、作業者は安定した姿勢で保守作業を実施することができる。 In addition, since the drop prevention device 1 is configured to be hooked at several places on the top of the steel tower T, it is not necessary for the operator himself to hold the drop prevention device 1. That is, the worker can perform maintenance work with a stable posture.
図６から図９は落滴防止装置を伸縮させる状態を示すものであり、図６は落滴防止装置を最大限伸張させた状態を示し、（ａ）は一部省略した平面図、（ｂ）は一部省略した正面図である。
本発明の落滴防止装置１は、連結部材６を中間用角度調節板１９部分で角度を調節することにより、落滴防止装置１の全長Ｌ１〜Ｌ４を調節することができる。例えば、長いがいし装置ｉの保守作業を行う際には、図６（ａ）、（ｂ）に示すように、長辺枠部材７の全部の連結部材６を一直線状の状態にする。このとき落滴防止袋３も同じように全長Ｌ１まで展開される。連結部材６は中間用角度調節板１９で仮止めされているので、所望の長さで維持することができ、保守作業中に落滴防止装置１の全長Ｌ１が変化するという不具合は生じない。
6 to 9 show a state in which the drop-preventing device is extended and contracted, FIG. 6 shows a state in which the drop-preventing device has been extended to the maximum extent, (a) is a plan view partially omitted, and (b) ) Is a partially omitted front view.
The drop-preventing device 1 of the present invention can adjust the total lengths L1 to L4 of the drop-preventing device 1 by adjusting the angle of the connecting member 6 at the intermediate angle adjusting plate 19 portion. For example, when performing maintenance work on the long insulator device i, as shown in FIGS. 6A and 6B, all the connecting members 6 of the long side frame member 7 are in a straight line state. At this time, the drop-preventing bag 3 is similarly developed to the full length L1. Since the connecting member 6 is temporarily fixed by the intermediate angle adjusting plate 19, it can be maintained at a desired length, and there is no problem that the total length L1 of the drop-preventing device 1 changes during maintenance work.
また、１箇所の保守作業が終了したら、落滴防止装置１の枠材２を縮める際に、落滴防止袋３の周縁部には、長辺枠部材７の連結部材６の連結部分と中間用角度調節板１９の連結部分に折り目２１があるので、折り曲げやすくコンパクトに畳めることができる。 Further, when the maintenance work at one place is completed, when the frame material 2 of the drop prevention device 1 is shrunk, the peripheral portion of the drop prevention bag 3 is located between the connecting portion of the connecting member 6 of the long side frame member 7 and the intermediate portion. Since the connecting portion of the angle adjusting plate 19 has a fold line 21, it can be easily folded and can be folded compactly.
図７は落滴防止装置の全体を少し縮めた状態を示し、（ａ）は一部省略した平面図、（ｂ）は一部省略した正面図である。図８は落滴防止装置の全体を更に少し縮めた状態を示し、（ａ）は一部省略した平面図、（ｂ）は一部省略した正面図である。
次に、図６に示した状態から、連結部材６を中間用角度調節板１９部分で角度を変える。図７（ａ）、（ｂ）に示すように、落滴防止装置１の全長Ｌ２をやや短くすることができる。更に、図８（ａ）、（ｂ）に示すように、落滴防止装置１の全長Ｌ３を更に短くすることができる。このときも連結部材６は中間用角度調節板１９で仮止めされているので、所望の長さを維持することができる。
FIGS. 7A and 7B show a state in which the entire drop-preventing device is slightly shrunk, wherein FIG. 7A is a partially omitted plan view and FIG. 7B is a partially omitted front view. FIGS. 8A and 8B show a state in which the entire drop-preventing device is further shrunk, in which FIG. 8A is a partially omitted plan view, and FIG.
Next, from the state shown in FIG. 6, the angle of the connecting member 6 is changed at the intermediate angle adjusting plate 19 portion. As shown in FIGS. 7A and 7B, the total length L2 of the drop-preventing device 1 can be slightly shortened. Furthermore, as shown to Fig.8 (a), (b), the full length L3 of the dripping prevention apparatus 1 can further be shortened. Also at this time, since the connecting member 6 is temporarily fixed by the intermediate angle adjusting plate 19, a desired length can be maintained.
図９は落滴防止装置の両端を部分的に縮めた状態を示し、（ａ）は一部省略した平面図、（ｂ）は一部省略した正面図である。
なお、連結部材６は中間用角度調節板１９部分で自由に角度調節することができるので、図７、図８に示すように、常に全連結部材６を同様な角度に調節する必要はない。例えば、図９（ａ）、（ｂ）に示すように、中間は連結部材６を一直線状の状態にし、両端は部分的に縮めた状態にして縮めることができる。このようにすることで、がいし装置ｉの下方が、落滴防止装置１の横幅を広い状態を維持しながら、落滴防止装置１の全長Ｌ４を短くすることができる。
落滴防止装置１を運搬又は保管するときは、図８に示す状態から更に縮めてコンパクトな状態にする。長期に使用しないときは、枠材２と落滴防止袋３とを分離して保管することも可能である。
FIGS. 9A and 9B show a state in which both ends of the drop-preventing device are partially shrunk, wherein FIG. 9A is a partially omitted plan view and FIG. 9B is a partially omitted front view.
Since the angle of the connecting member 6 can be freely adjusted by the intermediate angle adjusting plate 19 portion, it is not always necessary to adjust all the connecting members 6 to the same angle as shown in FIGS. For example, as shown in FIGS. 9A and 9B, the connecting member 6 can be in a straight state at the middle, and both ends can be contracted in a partially contracted state. By doing in this way, the lower part of the drop apparatus 1 can shorten the full length L4 of the drop prevention apparatus 1, maintaining the state where the width of the drop prevention apparatus 1 is wide.
When transporting or storing the drop-preventing device 1, it is further reduced from the state shown in FIG. 8 to a compact state. When not in use for a long time, the frame material 2 and the drip-proof bag 3 can be separated and stored.
