Description

本発明は、間接活線工作業で使用される絶縁操作棒に取付可能な補助グリップ及び当該補助グリップを備えた絶縁操作棒に関する。   The present invention relates to an auxiliary grip that can be attached to an insulating operation rod used in indirect hot wire work and an insulating operation rod including the auxiliary grip.

電線路の保守工事の多くは、現在、当該電線路を停電することなく、間接活線作業によって作業者の安全を担保しつつ実施されている。間接活線作業では、通常、作業者が高所作業車のバケット上などにてヤットコなどの間接把持工具や絶縁操作棒などを操作し、離れた位置にある充電状態の電線などを把持し、電気機器を取り付けまたは取り外しなどが行われる。   Many maintenance work for electric lines is currently carried out while ensuring the safety of workers through indirect hot-line work without powering down the electric lines. In indirect hot wire work, the operator usually operates an indirect gripping tool such as a yatco or an insulation operation rod on the bucket of an aerial work vehicle, etc., and grips a charged electric wire etc. at a remote position, Electrical equipment is installed or removed.

このような間接活線作業では、図6に示すような共用操作棒がよく使用される。この共用操作棒40は、棒体41の先端部に先端工具装着用の連結金具42を備え、また手元側の端部(基端部)にソケット連結部45を備えている。連結金具42は、略円柱状の外形を有し、その軸線方向先端面に当該方向に進退可能であり、内蔵されたバネによって当該方向基端側への押込み力に抗して突出方向に付勢される可動突部42aを備え、その側面の対向する位置には係合ピン43、44がそれぞれ突設されたものである。また、ソケット連結部45は、先端側(棒体41側)の端部が閉塞され、その軸線方向基端側が開口する円筒カップ状の外形を有し、その周側面の対向する位置にそれぞれ側面視略T字型をなし、鈎型の端部46a、46aを有する案内溝46、46(図6では、一方の案内溝のみ図示)が形成されたものである。   In such indirect hot line work, a common operation bar as shown in FIG. 6 is often used. The common operation bar 40 includes a connection fitting 42 for attaching a tip tool to a distal end portion of a rod body 41, and a socket connection portion 45 at an end portion (base end portion) on the proximal side. The connection fitting 42 has a substantially cylindrical outer shape, and can move forward and backward in the axial direction front end surface thereof, and is attached in the protruding direction against the pushing force toward the base end side in the direction by a built-in spring. The movable projecting portion 42a is energized, and engaging pins 43 and 44 project from the opposing positions on the side surfaces thereof. Further, the socket connecting portion 45 has a cylindrical cup-shaped outer shape whose end on the distal end side (the rod body 41 side) is closed and whose proximal end in the axial direction is open, and each side surface is located at a position facing the peripheral side surface. Guide grooves 46 and 46 (in FIG. 6, only one guide groove is shown) having a substantially T-shape and having saddle-shaped end portions 46a and 46a are formed.

この共用操作棒40には、その先端に種々の先端工具を装着可能であり、例えば接地短絡器具の取付・撤去、高圧引き下げ線の皮むき、工事用開閉器やHGの架線への付属ケーブルの取付・撤去等などの間接活線作業の場合、図7に例示されるような先端工具が装着される。図7(a)に示す先端工具50は、先端にネジ回し部51を備え、同図(b)に示す先端工具55(以下では、ナット回し器という。)は、先端の開口56aにナットを収容するソケット部56を備えたものであり、いずれも基端側にワンタッチで共用操作棒の先端に装着できるようにソケット連結部52、57を備えている。   This common operation rod 40 can be equipped with various tip tools at its tip. For example, installation / removal of a grounding short-circuit device, peeling of a high-voltage pull-down line, a construction switch, and an attached cable to an HG overhead wire In the case of indirect hot-line work such as attachment / removal, a tip tool as illustrated in FIG. 7 is attached. The tip tool 50 shown in FIG. 7A includes a screw driver 51 at the tip, and the tip tool 55 (hereinafter referred to as a nut driver) shown in FIG. 7B has a nut in the opening 56a at the tip. The socket portion 56 is provided, and both are provided with socket coupling portions 52 and 57 so that the base end side can be attached to the distal end of the common operation rod with one touch.

図8は、図6に示す共用操作棒の先端に図7に示す先端工具を装着した間接活線作業の一例を示している。不図示の高所作業車のアーム80先端のバケット81から、2名の作業者J1、J2が電柱60の上部の腕金61に鳥害防止器63の取付作業を行っている。この作業では、作業者J1がヤットコ59にて鳥害防止器63を把持してその取付金具を腕金61の所定の取付位置に配置し、作業者J2が当該取付位置の略真下から先端に先端工具としてナット回し器55を装着した共用操作棒40をその軸心周りに回転させて取付金具のナットを締め、鳥害防止器63を腕金61に固定する。   FIG. 8 shows an example of an indirect hot line operation in which the tip tool shown in FIG. 7 is attached to the tip of the common operation rod shown in FIG. Two workers J1 and J2 are performing attachment work of the bird damage prevention device 63 to the arm metal 61 on the upper part of the utility pole 60 from the bucket 81 at the tip of the arm 80 of an aerial work vehicle (not shown). In this work, the worker J1 grips the bird damage prevention device 63 with the Yatco 59 and places the mounting bracket at a predetermined mounting position of the arm 61, and the worker J2 moves from approximately right below the mounting position to the tip. The common operation rod 40 equipped with a nut turning device 55 as a tip tool is rotated around its axis to tighten the nut of the mounting bracket, and the bird damage prevention device 63 is fixed to the arm bracket 61.

また、図8では、作業者J3が安全帯72によって落下防止の措置をとった上で、電柱60に装着した仮の足場から、柱上トランス70の1次側に至る高圧引下線67の途中に設置された高圧カットアウト69の交換作業を行っている。この交換作業では、先端に図7に示す先端工具50を装着した共用操作棒40を用い、当該先端工具50の先端を高圧引下線67の取付部のネジにあてがい、その軸心周りに回転させて当該ネジを緩めることで高圧カットアウト69から高圧引下線67を切り離し、また当該ネジを締めることで、高圧引下線67を高圧カットアウト69に接続することが必要になる。また、高圧カットアウト69の取換作業においても、このようなネジの締め緩めが必要になる。   Further, in FIG. 8, the worker J3 takes a measure for preventing the fall by the safety belt 72 and then goes along the high-voltage underline 67 from the temporary scaffold attached to the utility pole 60 to the primary side of the pole transformer 70. The high-pressure cutout 69 installed in is being replaced. In this replacement operation, the common operation rod 40 having the tip tool 50 shown in FIG. 7 attached to the tip is used, the tip of the tip tool 50 is applied to the screw of the attachment portion of the high-voltage underline 67, and the shaft is rotated about its axis. It is necessary to disconnect the high-voltage underline 67 from the high-pressure cutout 69 by loosening the screw and to connect the high-voltage underline 67 to the high-pressure cutout 69 by tightening the screw. Further, such screw tightening / loosening is also necessary in the replacement work of the high-pressure cutout 69.

間接活線作業においては、このように作業者が共用操作棒をその軸心周りに回転させて作業を実施する場合が少なくない。このような場合、作業者は共用操作棒における棒体部41の操作端寄りの2か所を両手でそれぞれ握ってこれを回転させるが、当該棒体部41の直径が小さいため、作業者がこれを回転させるために力を加えにくく、回転トルクを十分に先端に伝達できないという問題があった。また、このように側方から共用操作棒を握るので、その操作中に誤って当該操作棒を落下させる危険性があった。   In indirect hot-line work, there are not a few cases in which an operator performs work by rotating the common operation rod around its axis. In such a case, the operator grasps two positions near the operation end of the bar body portion 41 of the common operation rod with both hands and rotates them. However, since the diameter of the bar body portion 41 is small, the operator There is a problem that it is difficult to apply a force to rotate this, and the rotational torque cannot be sufficiently transmitted to the tip. Further, since the common operation rod is gripped from the side in this way, there is a risk of accidentally dropping the operation rod during the operation.

以下、添付図面を参照して本発明の補助グリップの実施形態について詳細に説明する。図1は、本発明の共用操作棒補助グリップの実施形態の一例を示しており、(a)は側面図、(b)は平面図である。この図に示すように、本発明の共用操作棒補助グリップ1は、連結金具10と、握り部14とを必須の構成としている。   Hereinafter, embodiments of an auxiliary grip according to the present invention will be described in detail with reference to the accompanying drawings. 1A and 1B show an example of an embodiment of a shared operation bar auxiliary grip according to the present invention, in which FIG. 1A is a side view and FIG. 1B is a plan view. As shown in this figure, the shared operation rod auxiliary grip 1 of the present invention has a connecting fitting 10 and a grip 14 as essential components.

連結金具10は、その側面の対向する位置に係合ピン11、12が突設されており、共用操作棒の手元側端部に設けられたソケット連結部に係合可能とされている。この連結金具10の外形形状及びサイズ、係合ピンの突設位置及びそのサイズについては、相手方のソケット連結部(後述)の形状に応じて適宜設定することができる。通常、連結金具などに関する規格に準拠した規格品が用いられる。   Engagement pins 11 and 12 protrude from the coupling metal 10 at opposite positions on the side surfaces thereof, and can be engaged with a socket coupling portion provided at the proximal end of the common operation rod. About the external shape and size of this connection metal fitting 10, the protrusion position of an engagement pin, and its size, it can set suitably according to the shape of the other party socket connection part (after-mentioned). Usually, a standard product conforming to a standard related to a connecting metal fitting is used.

本実施形態における握り部14は、略楕円球の外形形状を備え、その短軸に平行な中心線が前記連結金具10の軸線方向に合致するように当該連結金具10の基端側に連結されている。連結金具10と握り部14とは、分離可能に連結されていてもよく分離不能に連結されていてもよい。後者の場合、握り部14は連結金具10に対して着脱自在とすることができる。   The grip portion 14 in the present embodiment has a substantially elliptical outer shape, and is connected to the base end side of the connection fitting 10 so that the center line parallel to the short axis thereof matches the axial direction of the connection fitting 10. ing. The connection fitting 10 and the grip 14 may be connected so as to be separable or may be connected so as not to be separable. In the latter case, the grip portion 14 can be attached to and detached from the connection fitting 10.

握り部14の外形形状は、図1に示すような略楕円球に限定されず、作業者の握りやすさを考慮して種々の外形形状のなかから適宜選択することができる。図2は、そのような握り部の外形形状の別の例を示している。図2において、(a)は各頂角を円弧状に、また各辺を内側に湾曲させ、周方向に凹凸が連続して形成された横断面形状が略菱形の握り部15aを示している。また、図2(b)は図2(a)と同様に各頂角を円弧状に、また各辺を同様の曲率にて内側に湾曲させ、周方向に凹凸が連続して形成された横断面形状略正八角形の握り部15bを示している。これら図1および図2に例示するように、握り部(14、15a、15b)の外形形状は、回転対称性、特には連結金具の軸心を回転中心とする回転対称性を備えていることが好ましい。   The outer shape of the grip portion 14 is not limited to a substantially elliptical sphere as shown in FIG. 1, and can be appropriately selected from various outer shapes in consideration of ease of gripping by the operator. FIG. 2 shows another example of the outer shape of such a grip portion. In FIG. 2, (a) shows a grip portion 15a having a substantially rhombic cross-sectional shape in which each apex angle is curved in an arc and each side is curved inward, and unevenness is continuously formed in the circumferential direction. . Further, FIG. 2B is a cross-sectional view in which each apex angle is arcuate and each side is curved inward with the same curvature as in FIG. 2A, and irregularities are continuously formed in the circumferential direction. A grip portion 15b having a substantially regular octagonal shape is shown. As illustrated in FIGS. 1 and 2, the outer shape of the grip portion (14, 15 a, 15 b) has rotational symmetry, in particular rotational symmetry about the axis of the coupling metal. Is preferred.

この握り部14の幅W(図1参照)は、本発明の補助グリップを連結する共用操作棒における棒体部の直径よりも大きく設定される。具体的には、幅Wは、約50〜100mm程度、好ましくは約60〜80mm程度に設定できる。ここで、握り部14の幅Wとは、連結金具10の軸線方向に直交する任意の方向の幅、特に握り部が、図2に示すように、その側面に周方向に凹凸が連続して形成されている場合には、対向する凹面間の最小幅をいうものとする。また、握り部14の高さLは、通常、約20〜80mm程度、好ましくは約40〜60mm程度に設定できる。握り部14のこれらのサイズは、作業者がその基端側からこれを握った際の握りやすさや力の加え易さなどを考慮して前記範囲内で適宜設定することができる。また、握り部14について、その他のサイズを規定する必要がある場合には、作業者がその基端側からこれを握った際の握りやすさや力の加え易さなどを考慮して当該その他のサイズを決定できる。   The width W (see FIG. 1) of the grip portion 14 is set to be larger than the diameter of the rod body portion in the common operation rod for connecting the auxiliary grip of the present invention. Specifically, the width W can be set to about 50 to 100 mm, preferably about 60 to 80 mm. Here, the width W of the grip portion 14 is a width in an arbitrary direction orthogonal to the axial direction of the connection fitting 10, and in particular, the grip portion has unevenness in the circumferential direction on its side surface as shown in FIG. 2. When formed, the minimum width between opposing concave surfaces shall be said. Moreover, the height L of the grip part 14 can be normally set to about 20-80 mm, preferably about 40-60 mm. These sizes of the grip portion 14 can be appropriately set within the above range in consideration of ease of gripping when the operator grips the grip portion 14 from the base end side, ease of applying force, and the like. In addition, when it is necessary to define other sizes for the grip part 14, the other parts are considered in consideration of ease of gripping when the operator grips the grip part 14 from the proximal end side and ease of applying force. The size can be determined.

連結金具10と握り部14との間には、図1に示すように、連結金具10の軸心とは同心に配置され、その周側面にローレット加工を施した円柱部分を設けることができる。本明細書では、この部分を「ローレット円柱部」ということとする。このローレット円柱部16は、通常、共用操作棒40の手元端部におけるソケット連結部に本発明の補助グリップ1を係合連結する際に、作業者がこの補助グリップをねじって回転させやすいように設けられているものである。   As shown in FIG. 1, a cylindrical portion that is concentric with the axial center of the connection fitting 10 and is knurled on the peripheral side surface can be provided between the connection fitting 10 and the grip portion 14. In this specification, this portion is referred to as a “knurled cylindrical portion”. The knurled cylindrical portion 16 is usually configured so that an operator can easily rotate the auxiliary grip by twisting the auxiliary grip 1 when the auxiliary grip 1 of the present invention is engaged and connected to the socket connecting portion at the proximal end of the common operation rod 40. It is provided.

このローレット円柱部16には、その内部に連結金具10の軸心に回転中心を合致させて回転方向規制手段(不図示)を内蔵させることができる。この回転方向規制手段は、握り部14を握って一方向に回転力を加えた場合には連結金具10にその回転力を伝達するが、反対方向に回転力を加えた場合には握り部14が空転し、連結金具10にその回転力が伝達されないように構成されたものである。このような回転方向規制手段の具体例としては、ラチェット機構部、ワンウエイクラッチなどが挙げられる。このような回転方向規制手段を備える場合には、必要ならば、連結金具10に回転力を伝達する回転方向(正転、逆転)を切り換える公知の切換手段を備えることができる。   The knurled cylindrical portion 16 can incorporate a rotation direction restricting means (not shown) with its center of rotation coincident with the axis of the connecting fitting 10. This rotational direction restricting means transmits the rotational force to the connection fitting 10 when the gripping portion 14 is gripped and a rotational force is applied in one direction, but when the rotational force is applied in the opposite direction, the gripping portion 14 is transmitted. Is configured so that it does not rotate and its rotational force is not transmitted to the connecting fitting 10. Specific examples of such rotation direction regulating means include a ratchet mechanism and a one-way clutch. In the case of providing such a rotation direction regulating means, a known switching means for switching the rotation direction (forward rotation, reverse rotation) for transmitting the rotational force to the connection fitting 10 can be provided if necessary.

このローレット円柱部16はまた、連結金具10と握り部14とが分離可能な場合には、これらを連結する連結具の一部としても構成することもできる。この場合、作業者は片手でこのローレット円柱部16を把持し、他方の手で握り部14を握り、両者を例えば回転させるなどの従来公知の方法で連結するようにしてもよい。   This knurled columnar part 16 can also be configured as a part of a connecting tool for connecting the connecting metal fitting 10 and the grip 14 when they can be separated. In this case, the operator may hold the knurled cylindrical portion 16 with one hand, hold the grip portion 14 with the other hand, and connect them by a conventionally known method such as rotating them.

図3は、本発明の補助グリップの実施形態の別の例を示しており、(a)は側面図、(b)は平面図、(c)は底面図である。この図に示す実施形態の補助グリップ2では、握り部14の基端側にソケット連結部18を内蔵している点が図1に示す実施形態と相違しており、それ以外の構成については図1に示す実施形態と本質的に変わるところはない。そのため、以下では、図1に示す実施形態と共通する各部についての重複した説明は省略する。   FIG. 3 shows another example of the embodiment of the auxiliary grip of the present invention, in which (a) is a side view, (b) is a plan view, and (c) is a bottom view. The auxiliary grip 2 of the embodiment shown in this figure is different from the embodiment shown in FIG. 1 in that the socket connecting portion 18 is built in the proximal end side of the grip portion 14, and the other configurations are shown in FIG. There is essentially no difference from the embodiment shown in FIG. Therefore, in the following, redundant description of each part common to the embodiment shown in FIG. 1 is omitted.

本実施形態において、ソケット連結部18は、その開口方向が連結部材10の軸線方向に合致するように握り部14内に埋め込まれている。このソケット連結部18は、先端側(連結金具10側)の端部が閉塞され、その軸線方向基端側が握り部14の基端面から露出した状態で開口する円筒カップ状の外形を有し、その周側面の対向する位置にそれぞれ側面視略T字型をなし、鈎型の端部19a、19aをそれぞれ有する案内溝19、19(図3(a)では、一方の案内溝のみ図示)が形成されたものである。ソケット連結部18としては、共用操作棒40におけるソケット連結部45と同様の形状およびサイズを備えたもの、又は規格品を使用できる。このソケット連結部18には、これに係合可能な連結金具を備えた共用操作棒やこれよりも短尺の足し棒などを連結することができる。   In the present embodiment, the socket connecting portion 18 is embedded in the grip portion 14 so that the opening direction thereof matches the axial direction of the connecting member 10. The socket connecting portion 18 has a cylindrical cup-shaped outer shape that is open in a state in which the end portion on the distal end side (the connecting fitting 10 side) is closed and the proximal end side in the axial direction is exposed from the proximal end surface of the grip portion 14. Guide grooves 19 and 19 (in FIG. 3 (a), only one guide groove is shown) each having a substantially T-shape in side view and having saddle-shaped end portions 19a and 19a at opposing positions on the peripheral side surfaces. It is formed. As the socket connection part 18, what has the same shape and size as the socket connection part 45 in the common operation rod 40, or a standard product can be used. The socket connecting portion 18 can be connected to a common operation rod provided with a connecting metal fitting that can be engaged with the socket connecting portion 18 or an adder rod shorter than this.

図4は、図1に示した本発明の補助グリップを共用操作棒に装着する方法を説明するための図である。この図に示すように、本発明の補助グリップ1の連結金具10の対向する2つの係合ピン11、12を共用操作棒40の手元側端部の対向する2つの案内溝46、46に合わせ、補助グリップ1を当該ソケット連結部45の開口内に押込む(図4(a)参照)。係合ピン11、12が、略T字型の案内溝46、46の先端側の端縁に当接するまで押し込んだ後(図4(b)参照)、補助グリップ1を時計方向あるいいは反時計方向のいずれかの方向にねじって回転させる。そうして案内溝46、46の両端にある端部46a、46aまで係合ピン11、12を摺動させる。このとき、ソケット連結部45の開口内の閉塞面によって連結金具10内に押込まれた可動突部10aが内部のバネによってその押込み力に抗して突出方向に押し出され、それに伴い係合ピン11、12は各案内溝46の端部46aにそれぞれ嵌合することになる。係合ピン11、12は各案内溝46の端部46aに付勢下に収まった状態となるため、通常、この補助グリップ1を装着した共用操作棒40を用いてこれに回転トルクを加えるような場合でも、補助グリップ1が共用操作棒40とは独立して回転することはなく、また分離することもない。なお、図3に示した本発明の補助グリップ   FIG. 4 is a view for explaining a method of mounting the auxiliary grip of the present invention shown in FIG. 1 on a common operation rod. As shown in this figure, the two opposing engaging pins 11 and 12 of the coupling fitting 10 of the auxiliary grip 1 of the present invention are aligned with the two opposing guide grooves 46 and 46 at the proximal end of the common operation rod 40. The auxiliary grip 1 is pushed into the opening of the socket connecting portion 45 (see FIG. 4A). After the engaging pins 11 and 12 are pushed in until they contact the end edges of the substantially T-shaped guide grooves 46 and 46 (see FIG. 4B), the auxiliary grip 1 is clockwise or counterclockwise. Twist clockwise to rotate in either direction. Then, the engaging pins 11 and 12 are slid to the end portions 46a and 46a at both ends of the guide grooves 46 and 46, respectively. At this time, the movable projection 10a pushed into the coupling fitting 10 by the closing surface in the opening of the socket coupling portion 45 is pushed out in the protruding direction against the pushing force by the internal spring, and accordingly the engaging pin 11 is pushed. , 12 are fitted into the end portions 46a of the guide grooves 46, respectively. Since the engaging pins 11 and 12 are in a state of being urged into the end portions 46a of the respective guide grooves 46, the rotating torque is usually applied to the common operating rod 40 to which the auxiliary grip 1 is attached. Even in such a case, the auxiliary grip 1 does not rotate independently of the common operation rod 40 and does not separate. The auxiliary grip of the present invention shown in FIG.

図5は、本発明の補助グリップを装着した共用操作棒の使用例を示した図である。この図では先端工具の図示を省略しているが、図7に示すような先端工具を装着しているものとする。作業者は、図5に示すように、例えば左手LHで共用操作棒40の棒体部41を握り、右手RHで補助グリップ1の握り部14を共用操作棒40の軸線方向から握るようにする。このようにして当該共用操作棒40をその軸心周りに回転させる場合、握り部14は棒体部41の直径よりもその幅が大きいため、力を加えやすく、その結果十分な回転トルクが先端に伝達できるとともに、握り部14を安定して握ることができるので、作業中の共用操作棒40の落下を防止することができる。   FIG. 5 is a view showing an example of use of a common operation rod equipped with the auxiliary grip of the present invention. Although the illustration of the tip tool is omitted in this figure, it is assumed that the tip tool as shown in FIG. 7 is attached. As shown in FIG. 5, for example, the operator grasps the rod body portion 41 of the common operation rod 40 with the left hand LH, and grasps the grasp portion 14 of the auxiliary grip 1 from the axial direction of the common operation rod 40 with the right hand RH. . In this way, when the common operation rod 40 is rotated around its axis, the grip portion 14 has a width larger than the diameter of the rod body portion 41, so that it is easy to apply a force, and as a result, a sufficient rotational torque is obtained. Since the grip portion 14 can be stably gripped, the common operation rod 40 can be prevented from dropping during work.
