Description

この発明は、架空電線やクランプカバーの把手等の遠隔にある対象物を把持したり挟持したりするための先端部が取り付け可能な間接活線作業用工具用の共用部及びこの共用部に先端部を取り付けて成る間接活線作業用工具全体の構造に関する。   The present invention relates to a shared part for an indirect hot wire work tool to which a tip part for gripping or clamping a remote object such as an overhead electric wire or a handle of a clamp cover can be attached, and a tip to the common part. It is related with the structure of the whole tool for indirect hot wire work which attaches a part.

架空電線やクランプカバーの把手等の対象物を把持したり挟持したりするための一般的な間接活線作業用工具としては、例えば特許文献１の図７（ａ）に示されるような絶縁ヤットコや、同じく特許文献１の図７（ｂ）に示されるような共用操作棒（ホットスティックとも称する。以下、同じ。）及びこの共用操作棒の棒体部の先端に取り付けられる先端工具が挙げられる。   As a general indirect hot wire working tool for gripping or sandwiching an object such as an overhead electric wire or a handle of a clamp cover, for example, an insulating Yattco as shown in FIG. In addition, a common operation rod (also referred to as a hot stick; the same applies hereinafter) as shown in FIG. 7B of Patent Document 1 and a tip tool attached to the distal end of the rod body portion of the common operation rod can be mentioned. .

しかしながら、絶縁ヤットコの操作棒や先端工具が取り付けられる共用操作棒の棒本体は全体形状が直線状であるため、電柱の裏側や対象物までの途中に障害物があるような作業環境下では、絶縁ヤットコの把持部や共用操作棒の先端工具が対象物に届かないか、絶縁ヤットコの把持部や共用操作棒の先端工具が対象物に届いても対象物の把持・挟持作業が困難であるので、間接活線作業ができなかったり、間接活線作業が煩雑になったりするおそれがある。   However, since the overall shape of the rod body of the common operation rod to which the operation rod of the insulating Yatco and the tip tool is attached is linear, in a work environment where there is an obstacle on the back side of the utility pole or in the middle of the object, It is difficult to grip and hold the object even if the insulated tool gripping part or the common tool bar tip tool does not reach the object, or the insulated tool bar or common tool bar tip tool reaches the object. Therefore, there is a possibility that the indirect hot line work cannot be performed or the indirect hot line work becomes complicated.

一方で、間接活線工具の棒状体の軸線の向きを途中で変更するために、例えば特許文献１の図８（ｃ）に示されるように、間接活線工具の基部側部材の端部に菊座コネクタを設けると共に、間接活線工具の先端部側部材の端部に菊座コネクタに対応した菊座部を設けて、この菊座コネクタと菊座部とを例えば基部側部材の軸線と先端部側部材の軸線とが９０度の角度にて交差するように組み付けることを可能とした連結機構が既に公知になっている。   On the other hand, in order to change the direction of the axis of the rod-shaped body of the indirect live tool, on the end of the base side member of the indirect live tool, for example, as shown in FIG. In addition to providing a Kikuza connector, a Kikuza portion corresponding to the Kikuza connector is provided at the end of the tip side member of the indirect hot wire tool. A connecting mechanism that can be assembled so that the axis of the tip end side member intersects at an angle of 90 degrees is already known.

特開２００７−８２３３０号公報JP 2007-82330 A

もっとも、特許文献１に示される連結機構では、間接活線工具の棒状体の基部側部材と先端部側部材とが完全に分離していることから、間接活線工具の基部側部材側に操作部を設けても、間接活線工具の先端部側部材側に操作部の操作を伝達するための伝達手段を有していないので、基部側部材の先端に配することが可能な先端工具は、操作部からの伝達手段を必要としないバインド引掛具等に限定され、把持機構や挟持機構を有する先端工具を棒状体の先端部側部材の先端に取り付けることができない。   However, in the connection mechanism shown in Patent Document 1, the base side member and the tip end side member of the rod-shaped body of the indirect live tool are completely separated from each other, so that the operation is performed on the base side member side of the indirect live tool. Even if the portion is provided, since there is no transmission means for transmitting the operation of the operation portion on the distal end side member side of the indirect live tool, the tip tool that can be arranged at the distal end of the base side member is The tool is limited to a binding hook that does not require a transmission means from the operation unit, and a tip tool having a gripping mechanism or a clamping mechanism cannot be attached to the tip of the rod side member.

また、間接活線工具の棒状体の基部側部材と先端部側部材とが完全に分離しているので、菊座コネクタと菊座部との組み付けが不十分だと、菊座部を有する先端部側部材が地面等に落下するおそれもある。   In addition, since the base side member and the tip side member of the rod-shaped body of the indirect hot wire tool are completely separated, if the assembly of the Kikuza connector and the Kikuza seat is insufficient, the tip having the Kikusa seat There is also a possibility that the part side member may fall on the ground or the like.

一方で、間接活線作業用工具の先端部が棒状体に分離不可能に固定されていると、作業現場に複数の間接活線作業用工具を持ち込む必要があるので、把持機能や挟持機能等の伝達部材を必要とする先端部の間であっても、作業現場で先端部のみの交換を可能とすることが望まれる。また、先端部が破損すると間接活線作業用工具全体を廃棄する必要も生ずる。   On the other hand, if the tip of the indirect live work tool is fixed to the rod body so as not to be separated, it is necessary to bring multiple indirect live work tools to the work site. It is desired that only the tip portion can be exchanged at the work site even between the tip portions that require the transmission member. In addition, if the tip is damaged, the entire tool for indirect hot wire work needs to be discarded.

そこで、本発明は、架空電線やカバーの把手等の対象物を把持したり挟持したりするための機能を備えた先端部とこの先端部に操作部の操作を伝達する伝達部材とを備えながら、共用部の軸線の向きを複数箇所で変更することが可能で、先端部の交換もすることができる間接活線作業用工具の共用部及び間接活線作業用工具を提供することを目的とする。   Therefore, the present invention includes a distal end portion having a function for gripping or holding an object such as an overhead electric wire or a handle of a cover, and a transmission member that transmits the operation of the operation portion to the distal end portion. An object of the present invention is to provide a shared part of an indirect hot wire work tool and an indirect hot wire work tool which can change the direction of the axis of the common part at a plurality of locations and can also replace the tip part. To do.

この発明に係る間接活線作業用工具の共用部は、複数の棒状体部分で構成された共用部本体と、前記共用部本体の一方端側に配された操作部と、前記共用部本体の他方端側に配されて先端部を着脱自在に取り付けることができる先端部取付部とを有し、隣接する棒状体部分は、一方の棒状体部分から延出した被挟持突出部と他方の棒状体部分から延出して前記被挟持突出部を間に挟むことが可能な１対の挟持突出部とに回転軸を挿通して構成された関節部で回転自在に連結されていると共に前記関節部は当該関節部の回転を所要の位置でロックするロック機構を備えていることを特徴としている（請求項１）。間接活線作業用工具の共用部が備える関節部の数は例えば３つとなっている。また、間接活線作業用工具の共用部が備える操作部は作業員が手元で操作することができるものであり、例えば固定グリップとこの固定グリップに遠近する可動グリップとを有して構成され、可動グリップは先端部に操作部の操作を伝達することが可能なようにワイヤ等の伝達部材の一方端が連結されている。   The shared portion of the tool for indirect hot-wire work according to the present invention includes a shared portion main body configured by a plurality of rod-shaped body portions, an operation portion disposed on one end side of the shared portion main body, and the shared portion main body. A distal end mounting portion that is disposed on the other end side and can be detachably attached to the distal end portion, and the adjacent rod-shaped body portion includes a sandwiched protruding portion extending from one rod-shaped body portion and the other rod-shaped body portion The joint portion is rotatably connected to a pair of sandwiching protrusions extending from a body part and capable of sandwiching the sandwiched protrusions therebetween with a joint portion formed by inserting a rotation shaft. Is provided with a lock mechanism that locks the rotation of the joint at a required position (claim 1). The number of joints provided in the shared part of the tool for indirect hot wire work is, for example, three. In addition, the operation part provided in the shared part of the tool for indirect hot-wire work can be operated by a worker at hand, and is configured to have, for example, a fixed grip and a movable grip that is close to the fixed grip, The movable grip is connected to one end of a transmission member such as a wire so that the operation of the operation unit can be transmitted to the tip.

これにより、間接活線作業用工具の共用部を構成する複数の棒状体部分のうち隣接する棒状体部分は、これら棒状体部分同士が相対的に回転自在なように関節部で連結されているので、間接活線作業用工具の共用部は関節部で折り曲げることにより当該共用部の軸線の向きを複数箇所で変更することが可能であり、また、共用部の先端側に位置する棒状体部分が外れて落下するおそれもない。更に、ロック機構により隣接する棒状体部分が所望の角度で交差する位置において関節部の回転をロックすることができるので、共用部の全体形状を直線状の状態から複数箇所で折れ曲がった状態に変形させることが可能である。更にまた、間接活線作業用工具の共用部は、先端部取付部を有するので、先端部のみを交換することが可能である。   Thereby, the adjacent rod-shaped body portions among the plurality of rod-shaped body portions constituting the shared portion of the indirect hot wire working tool are connected by the joint portions so that these rod-shaped body portions are relatively rotatable. Therefore, it is possible to change the direction of the axis of the shared part at a plurality of locations by bending the shared part of the tool for indirect hot wire work at the joint part, and the rod-like body part located on the tip side of the shared part There is no danger of falling off and falling. Furthermore, because the lock mechanism can lock the rotation of the joint at the position where the adjacent rod-like body parts intersect at a desired angle, the entire shape of the common part is deformed from a straight state to a bent state at multiple locations. It is possible to make it. Furthermore, since the shared part of the tool for indirect hot-wire work has the tip part mounting part, it is possible to replace only the tip part.

より具体的には、前記ロック機構は、前記被挟持突出部に、当該被挟持突出部と前記挟持突出部とが前記回転軸を中心に相対的に回転しても前記挟持突出部と当接しない平坦部分を形成し、前記平坦部分の所要の部位に厚み方向に延びる有底の孔部を円弧状に複数並ぶように設け、前記一対の挟持突出部の少なくとも一方に、当該挟持突出部の厚み方向に延びると共に前記孔部の円弧状の並び方向と重なる位置に開口する貫通孔を設けて、前記貫通孔側からロックピンを挿入して前記孔部に前記ロックピンの先端を差し込むことで、前記関節部の回転を規制することを特徴としている（請求項２）。被挟持突出部の平坦部分のうち孔部の近傍には、孔部にロックピンが差し込まれたときの一方の棒状体部分と他方の棒状体部分との交差角度を示す数値、目盛り等が配置されていても良い。   More specifically, the lock mechanism contacts the sandwiched protrusion with the sandwiched protrusion even if the sandwiched protrusion and the sandwiched protrusion rotate relatively around the rotation axis. A flat portion is formed, and a plurality of bottomed hole portions extending in the thickness direction are provided in a required portion of the flat portion so as to be arranged in an arc shape, and at least one of the pair of sandwiching projections By providing a through hole extending in the thickness direction and opening at a position overlapping with the arcuate arrangement direction of the holes, inserting a lock pin from the through hole side and inserting the tip of the lock pin into the hole The rotation of the joint is restricted (claim 2). A numerical value, scale, etc., indicating the angle of intersection between one rod-like body portion and the other rod-like body portion when the lock pin is inserted into the hole portion is arranged in the vicinity of the hole portion in the flat portion of the sandwiched protruding portion May be.

これにより、回転軸を軸芯として挟持突出部を被挟持突出部の平坦部分の範囲内で任意の方向に回転させ、挟持突出部の貫通孔を被挟持突出部の孔部と合致させて、挟持突出部の貫通孔からロックピンを先端が被挟持突出部の孔部内に達するまで挿入する作業のみで、関節部の回転がロックされる。   Thereby, the pinching protrusion is rotated in an arbitrary direction within the range of the flat portion of the pinching protrusion with the rotation axis as the axis, and the through hole of the pinching protrusion is matched with the hole of the pinching protrusion. The rotation of the joint is locked only by inserting the lock pin from the through hole of the sandwiching protrusion until the tip reaches the hole of the sandwiching protrusion.

この発明に係る間接活線作業用工具は、請求項１又は請求項２に記載の間接活線作業用工具の共用部と前記操作部の操作が伝達されて可動部材を固定部材に遠近させる先端部とを備え、前記共用部の先端部取付部は、前記共用部本体内に収容されて前記操作部から延びる第１の伝達部材が取り付けられた嵌合部材を有し、前記嵌合部材は前記共用部本体内を当該共用部本体の軸方向に移動することができると共に、前記先端部は、前記可動部材と連結された第２の伝達部材と、前記先端部内に収容されて前記嵌合部材と嵌合可能な連結部材と、前記連結部材と前記第２の伝達部材とを連結する第３の伝達部材とを有し、前記連結部材は前記先端部内を当該先端部の軸方向に移動することができることを特徴としている（請求項３）。   The tool for indirect hot-wire work according to the present invention is a tip for transmitting the operation of the common part and the operation part of the tool for indirect hot-line work according to claim 1 or 2 to move the movable member closer to the fixed member. A front end portion mounting portion of the common portion has a fitting member to which a first transmission member that is accommodated in the common portion main body and extends from the operation portion is attached, and the fitting member is The common portion main body can move in the axial direction of the common portion main body, and the tip portion is accommodated in the tip portion and the second transmission member connected to the movable member, and the fitting A connecting member that can be fitted to the member; and a third transmitting member that connects the connecting member and the second transmitting member. The connecting member moves in the axial direction of the distal end portion within the distal end portion. (Claim 3).

これにより、共用部の先端部取付部に先端部を取り付けたときに、嵌合部材と連結部材とが連結されることで、操作部から延びる第１の伝達部材は嵌合部材、連結部材を経て第３の伝達部材、更には第２の伝達部材と連結された後、先端部の可動部材に連結された状態となるので、操作部の操作が先端部の可動部材に伝達される。   Thereby, when a front-end | tip part is attached to the front-end | tip part attachment part of a shared part, a 1st transmission member extended from an operation part is a fitting member and a connection member by connecting a fitting member and a connection member. Then, after being connected to the third transmission member, and further to the second transmission member, the state is connected to the movable member at the distal end portion, so that the operation of the operation portion is transmitted to the movable member at the distal end portion.

以上のように、本発明によれば、間接活線作業用工具の共用部を構成する複数の棒状体部分のうち隣接する棒状体部分は、これら棒状体部分同士が相対的に回転自在なように関節部で連結されているので、間接活線作業用工具の共用部は関節部で折り曲げることにより当該共用部の軸線の向きを複数箇所で変更することが可能である。このため、電柱の裏側にある対象物や途中に障害物がある対象物に対する間接活線作業であっても、関節部を回転させて棒状体部分同士の交差する角度を決定した後、ロック機構で関節部の回転をロックして共用部が折れ曲がった状態を固定して、この共用部に作業目的に好適な先端部を取り付けた間接活線作業用工具を用いることで、前記対象物を把持したり挟持したりすることが可能となる。   As described above, according to the present invention, adjacent rod-like body portions among the plurality of rod-like body portions constituting the shared portion of the tool for indirect hot-wire work are such that these rod-like body portions are relatively rotatable. Since the joint part of the tool for indirect hot wire work is bent at the joint part, the direction of the axis of the common part can be changed at a plurality of locations. For this reason, even in indirect hot-line work for objects on the back side of power poles or objects with obstacles in the middle, after determining the angle at which the rod-shaped body parts intersect by rotating the joint part, the locking mechanism The joint portion is locked by locking the state where the common portion is bent, and the object is gripped by using an indirect hot wire work tool with a tip portion suitable for work purpose attached to the common portion. Can be held or pinched.

また、本発明によれば、共用部の棒状体部分同士が分離しておらず関節部で連結されているため、共用部の先端側に位置する棒状体部分が外れて落下するという不具合を防止することができるので、間接活線作業の安全性を高めることが可能である。   In addition, according to the present invention, since the rod-shaped body portions of the shared portion are not separated from each other and are connected by the joint portion, the problem that the rod-shaped body portion located on the distal end side of the shared portion is detached and falls is prevented. Therefore, it is possible to increase the safety of indirect hot-line work.

特に請求項２に記載の発明によれば、回転軸を軸芯として挟持突出部を被挟持突出部の平坦部分の範囲内で任意の方向に回転させ、挟持突出部の貫通孔を被挟持突出部の孔部と合致させて、挟持突出部の貫通孔からロックピンを先端が被挟持突出部の孔部内に達するまで挿入する作業のみで、関節部の回転をロックすることができるので、本発明の間接活線作業用工具を準備する作業の効率化、迅速化を図ることができる。   In particular, according to the second aspect of the invention, the pinching protrusion is rotated in an arbitrary direction within the range of the flat portion of the pinching protrusion with the rotation shaft as the axis, and the through hole of the pinching protrusion is held and protruding. The rotation of the joint part can be locked only by inserting the lock pin from the through hole of the clamping projection part until the tip reaches the hole part of the clamping projection part. It is possible to improve the efficiency and speed of the work for preparing the indirect hot wire working tool of the invention.

特に請求項３に記載の発明によれば、共用部の先端部取付部に先端部を取り付けたときに、嵌合部材と連結部材とが連結されることで、操作部から延びる第１の伝達部材は嵌合部材、連結部材を経て第３の伝達部材、更には第２の伝達部材と連結された後、先端部の可動部材に連結された状態となるので、先端部を交換可能としながら、操作部の操作を先端部の可動部材に確実に伝達することが可能となる。   In particular, according to the third aspect of the present invention, the first transmission extending from the operation portion is achieved by connecting the fitting member and the connecting member when the tip portion is attached to the tip end attaching portion of the shared portion. Since the member is connected to the third transmission member via the fitting member and the connection member, and further connected to the second transmission member, and then connected to the movable member at the tip, the tip can be replaced. The operation of the operation unit can be reliably transmitted to the movable member at the tip.

更に、可動グリップ４２は、先端部１０に操作部４の操作を伝達するための伝達部材４５が連結されている。伝達部材４５は、単なるワイヤのみで構成されても良いが、この実施例では、図３（ｂ）に示されるように、先端部分がネジ切りされたワイヤ４５１と、可動グリップ４２に固定された連結部４５２と、連結部４５２に回転自在に連結されると共にワイヤ４５１の先端部分が挿入可能な有底孔が形成され、有底孔の内周面はネジ切りされた回転部４５３とで構成されている。   Further, the movable grip 42 is connected to the distal end portion 10 with a transmission member 45 for transmitting the operation of the operation portion 4. The transmission member 45 may be composed of only a wire, but in this embodiment, as shown in FIG. 3B, the tip portion is fixed to the wire 451 and the movable grip 42. The connecting portion 452 includes a bottomed hole that is rotatably connected to the connecting portion 452 and into which the tip of the wire 451 can be inserted. The inner peripheral surface of the bottomed hole includes a threaded rotating portion 453. Has been.

これにより、回転部４５３の有底孔にワイヤ４５１の先端部分を挿入した状態で、回転部４５３を所要方向に回転させることにより、ワイヤ４５１の先端部分の回転部４５３の有底孔内への挿入深度が変わるので、ワイヤ４５１の長さや張度を回転部４５３の回転で調整することが可能になっている。ワイヤ４５１は絶縁素材で成る絶縁ワイヤが用いられる。   Thereby, in a state where the tip portion of the wire 451 is inserted into the bottomed hole of the rotating portion 453, the rotating portion 453 is rotated in a required direction, whereby the tip portion of the wire 451 enters the bottomed hole of the rotating portion 453. Since the insertion depth changes, the length and tension of the wire 451 can be adjusted by the rotation of the rotating unit 453. As the wire 451, an insulating wire made of an insulating material is used.

また、主に図４を用いて、先端部取付部５及び先端部１０の一例について説明する。図１、図２及び図４に示される先端部１０は、円柱状の接続部１０１と、接続部１０１に固定された固定部材１０２と、途中部位において軸部１０４を介して固定部材１０２に揺動自在に連結された可動部材１０３とを備えている。   Moreover, an example of the front-end | tip part attaching part 5 and the front-end | tip part 10 is demonstrated mainly using FIG. 1, 2, and 4, the distal end portion 10 is swung to the fixing member 102 via the columnar connecting portion 101, the fixing member 102 fixed to the connecting portion 101, and the shaft portion 104 in the middle portion. And a movable member 103 that is movably connected.

これにより、可動部材１０３は、その先端部分が軸部１０４を軸芯として揺動して固定部材１０２の先端部分に遠近することにより、固定部材１０２の先端部分と可動部材１０３の先端部分とで対象物を把持・挟持したり、対象物を把持・挟持した状態から離したりすることが可能になっている。そして、可動部材１０３は、軸部１０６を介して直線の細いロッド（棒体）状の伝達部材１０５の一方端部と連結されている。   As a result, the movable member 103 swings around the shaft portion 104 as the axis and moves away from the distal end portion of the fixed member 102, so that the distal end portion of the fixed member 102 and the distal end portion of the movable member 103 are separated. It is possible to hold and hold the object or to release the object from the held and held state. The movable member 103 is connected to one end portion of a linear thin rod (rod body) -like transmission member 105 via a shaft portion 106.

先端部１０の接続部１０１は、固定部材１０２が固定された側とは反対側端に開口部１０７を有し、この開口部１０７に棒状体部分３４の他の部位よりも外径寸法が小さい突出部５１を挿入させることにより、先端部１０の接続部１０１を共用部２の棒状体部分３４に取り付けることが可能になっているもので、開口部１０７の内周面にはネジ溝が形成されている。   The connecting portion 101 of the distal end portion 10 has an opening 107 at the end opposite to the side on which the fixing member 102 is fixed, and the opening 107 has a smaller outer diameter than other portions of the rod-like body portion 34. By inserting the protruding portion 51, the connecting portion 101 of the tip portion 10 can be attached to the rod-shaped body portion 34 of the common portion 2, and a screw groove is formed on the inner peripheral surface of the opening 107. Has been.

先端部１０の接続部１０１内には、開口部１０７と連通した空間部１０８が設けられている。空間部１０８は、接続部１０１の径方向寸法が相対的に小さな小幅部１０８ａと小幅部１０８ａより接続部１０１の径方向寸法が大きな大幅部１０８ｂとで成り、小幅部１０８ａは一方側が固定部材１０２が固定された側に開口している。そして、空間部の大幅部１０８ｂと開口部１０７との間には突出部１０９が接続部１０１の径方向に沿って環状に突出することで通孔部１１０が形成されている。   A space portion 108 communicating with the opening 107 is provided in the connection portion 101 of the distal end portion 10. The space portion 108 is composed of a small width portion 108a in which the radial dimension of the connection portion 101 is relatively small and a large portion 108b in which the radial size of the connection portion 101 is larger than the small width portion 108a. Is open on the fixed side. A projecting portion 109 projects annularly along the radial direction of the connecting portion 101 between the large portion 108 b of the space portion and the opening 107, thereby forming a through hole portion 110.

そして、前述した伝達部材１０５は、小幅部１０８ａの開口から挿入されて小幅部１０８ａ内に所要の割合の範囲（この実施例では伝達部材１０５の半分以上の範囲）が小幅部１０８ａに収容されているもので、その端部は大幅部１０８ｂ内に突出することが可能となっている。   The transmission member 105 described above is inserted from the opening of the small width portion 108a, and a range of a required ratio (a range of more than half of the transmission member 105 in this embodiment) is accommodated in the small width portion 108a. Therefore, the end portion can protrude into the large portion 108b.

空間部１０８の大幅部１０８ｂから開口部１０７にわたって連結部材１１１が収容されている。連結部材１１１は、大幅部１０８ｂの内周面との間に若干の隙間を有して大幅部１０８ｂ内をガタツキなく移動する大径部１１１ａと、この大径部１１１ａから延びて通孔部１１０内を挿通する小径部１１１ｂと、開口部１０７側に位置して通孔部１１０の内径寸法よりも大きな外径寸法を有するフランジ部１１１ｃと、フランジ部１１１ｃから突出した係合突部１１１ｄとで構成されている。係合突部１１１ｄの側面はネジ溝が切られている。そして、連結部材１１１の大径部１１１ａと伝達部材１０５の端部とは絶縁ワイヤ等の伝達部材１１２で連結されている。   The connecting member 111 is accommodated from the large portion 108 b of the space 108 to the opening 107. The connecting member 111 has a large-diameter portion 111a that moves slightly in the large-diameter portion 108b with a slight gap between the large-diameter portion 108b and a through-hole portion 110 that extends from the large-diameter portion 111a. A small-diameter portion 111b that is inserted through the inside, a flange portion 111c that is located on the opening 107 side and has an outer diameter that is larger than the inner diameter of the through-hole portion 110, and an engagement protrusion 111d that protrudes from the flange portion 111c. It is configured. The side surface of the engaging protrusion 111d is threaded. And the large diameter part 111a of the connection member 111 and the edge part of the transmission member 105 are connected by the transmission member 112, such as an insulated wire.

これにより、連結部材１１１の大径部１１１ａは、空間部１０８の大径部１１１ａ内を円滑に移動可能であると共に、連結部材１１１のフランジ部１１１ｃが突出部１０９に当接することにより、連結部材１１１の大径部１１１ａの小径部１１１ｂ側への移動は所要範囲までとなるように規制されている。そして、連結部材１１１の移動は、伝達部材１１２から伝達部材１０５を経て可動部材１０３に伝達され、可動部材１０３の軸部１０４を回転中心とした回転運動に変換される。   As a result, the large diameter portion 111a of the connecting member 111 can move smoothly in the large diameter portion 111a of the space portion 108, and the flange portion 111c of the connecting member 111 abuts on the protruding portion 109, whereby the connecting member The movement of the large-diameter portion 111a of 111 toward the small-diameter portion 111b is restricted so as to reach a required range. Then, the movement of the connecting member 111 is transmitted from the transmission member 112 to the movable member 103 via the transmission member 105, and is converted into a rotational movement with the shaft portion 104 of the movable member 103 as the rotation center.

先端部取付部５は、先端部１０の接続部１０１を取り付けるために前述した突出部５１を有するもので、この突出部５１の外周面には接続部１０１の開口部１０７の内周面に形成されたネジ溝と螺合可能なネジ溝が形成されている。また、先端部取付部５は、空間部７と連通した空間部５２を有し、この空間部５２は空間部７よりも棒状体部分３４の径方向寸法が小さいと共に突出部５１の先端面に開口している。   The tip attachment portion 5 has the protrusion 51 described above for attaching the connection portion 101 of the tip 10, and is formed on the outer peripheral surface of the protrusion 51 on the inner peripheral surface of the opening 107 of the connection portion 101. A screw groove that can be screwed with the formed screw groove is formed. Further, the tip end attachment portion 5 has a space portion 52 that communicates with the space portion 7, and the space portion 52 has a smaller dimension in the radial direction of the rod-like body portion 34 than the space portion 7, and the tip end surface of the protruding portion 51. It is open.

そして、先端部取付部５の空間部５２内には、嵌合部材５３が収容されている。嵌合部材５３は、空間部５２の内周面との間に若干の隙間を有して空間部５２内をガタツキなく棒状体部分３４の軸方向に沿って移動することが可能な外径寸法を有するもので、空間部５２の開口側に開口した係合孔５４が形成されていると共に係合孔５４とは反対側にて伝達部材４５のワイヤ４５１の端部が連結されている。また、嵌合部材５３の係合孔５４の内周面には連結部材１１１の係合突部のネジ溝と螺合可能なネジ溝が切られている。これにより、嵌合部材５３と連結部材１１１とは、係合孔５４に係合突部１１１ｄが螺合することにより棒状体部分３４及び先端部１０の軸方向に沿って一体的且つ円滑に移動することが可能となっている。   A fitting member 53 is accommodated in the space 52 of the tip end attachment 5. The fitting member 53 has a slight gap between the inner peripheral surface of the space portion 52 and an outer diameter dimension capable of moving in the space portion 52 along the axial direction of the rod-shaped body portion 34 without rattling. The engagement hole 54 opened on the opening side of the space 52 is formed, and the end of the wire 451 of the transmission member 45 is connected to the opposite side of the engagement hole 54. In addition, a thread groove that can be screwed with a thread groove of the engagement protrusion of the coupling member 111 is cut on the inner peripheral surface of the engagement hole 54 of the fitting member 53. As a result, the fitting member 53 and the connecting member 111 move integrally and smoothly along the axial direction of the rod-like body portion 34 and the distal end portion 10 by the engagement protrusion 111d being screwed into the engagement hole 54. It is possible to do.

このような先端部取付部５への先端部１０の取付構造とすることにより、操作部４を強く握り可動グリップ４２が固定グリップ４１側に近づくように操作したり、操作部４を握る力を弱めて可動グリップ４２が固定グリップ４１から離れるように操作したりすると、伝達部材４５が変位して嵌合部材５３、連結部材１１１が伝達部材４５の変位に応じて一体的に移動するため、連結部材１１１に連結された伝達部材１１２、伝達部材１１２に連結された伝達部材１０５も変位することから、操作部４の操作が先端部１０の可動部材１０３に確実に伝達され、可動部材１０３が軸部１０４を回転中心とした所要方向に回転するので、先端部１０が対象物Ａの把持・挟持やその把持・挟持状態の解除を行う機能を備えつつ、先端部取付部５に対し先端部１０を着脱自在に取り付けることが可能となる。これにより、壊れた先端部１０を新しい先端部１０に交換したり、ある対象物を把持・挟持するのに好適な機能を有する先端部１０から別の対象物を把持・挟持するのに好適な機能を有する先端部１０に交換したりすることが可能となる。すなわち、間接活線作業用工具１の共用部２は複数の先端部１０について共用のものとすることができる。   By adopting such a structure for attaching the distal end portion 10 to the distal end portion attaching portion 5, the operation portion 4 is strongly gripped and the movable grip 42 is operated so as to approach the fixed grip 41 side, or the force for grasping the operating portion 4 is increased. When the movable grip 42 is operated so that the movable grip 42 is separated from the fixed grip 41 by weakening, the transmission member 45 is displaced and the fitting member 53 and the connection member 111 move integrally according to the displacement of the transmission member 45. Since the transmission member 112 coupled to the member 111 and the transmission member 105 coupled to the transmission member 112 are also displaced, the operation of the operation unit 4 is reliably transmitted to the movable member 103 of the distal end portion 10, and the movable member 103 is pivoted. Since the tip 104 rotates in the required direction with the portion 104 as the center of rotation, the tip 10 has a function of gripping / clamping the object A and releasing the grip / clamping state, and with respect to the tip attachment portion 5 It is possible to mount the end 10 detachably. Thereby, it is suitable for exchanging the broken tip 10 with a new tip 10 or holding / holding another object from the tip 10 having a function suitable for holding / holding a certain object. It is possible to replace the tip portion 10 having a function. That is, the shared part 2 of the indirect hot wire working tool 1 can be shared by the plurality of tip parts 10.

そして、隣接する棒状体部分３１〜３４を連結する関節部６につて図５及び図６を用いて説明する。尚、図５、図６では棒状体部分３１と棒状体部分３２とを連結する関節部６を対象として説明するが、図５、図６の括弧書きで示すように、棒状体部分３２と棒状体部分３３とを連結する関節部６、棒状体部分３３と棒状体部分３４とを連結する関節部６も同様である。   And the joint part 6 which connects the adjacent rod-shaped body parts 31-34 is demonstrated using FIG.5 and FIG.6. 5 and 6, the joint portion 6 that connects the rod-shaped body portion 31 and the rod-shaped body portion 32 will be described as an object. However, as shown in parentheses in FIGS. 5 and 6, the rod-shaped body portion 32 and the rod-shaped body portion 32 are described. The same applies to the joint portion 6 that connects the body portion 33 and the joint portion 6 that connects the rod-like body portion 33 and the rod-like body portion 34.

関節部６は、棒状体部分３１から当該棒状体部分３１の軸方向に沿って延出した被挟持突出部６１と、棒状体部分３２から当該棒状体部分３２の軸方向に沿って延出して被挟持突出部６１を間に挟むことが可能な１対の挟持突出部６２、６３と、挟持突出部６２、６３で被挟持突出部６１を挟んだ状態で、これらの挟持突出部６２、６３及び被挟持突出部６１に挿通した回転軸６４とを有している。棒状体部分３１の被挟持突出部６１の両側は、伝達部材４５のワイヤ４５１を挿通するために略半円状に開口し、棒状体部分３１の空間部７に連通したものとなっている。また、挟持突出部６２、６３は、伝達部材４５のワイヤ４５１を挿通するために空間部７と連通し且つ棒状体部分３２の長手方向端側に開口した空間部６２１、６３１を内部に有すると共に被挟持突出部６１の側面に当接して挟むための壁部６２２、６３２を有している。これにより、関節部６は、被挟持突出部６１と挟持突出部６２、６３とについて、回転軸６４を回転中心として相対的に回転可能としている。   The joint portion 6 extends from the rod-shaped body portion 31 along the axial direction of the rod-shaped body portion 31 and from the rod-shaped body portion 32 along the axial direction of the rod-shaped body portion 32. A pair of sandwiching projections 62 and 63 capable of sandwiching the sandwiched projection 61, and the sandwiching projections 62 and 63 in a state where the sandwiching projection 61 is sandwiched between the sandwiching projections 62 and 63. And a rotating shaft 64 inserted through the sandwiched projecting portion 61. Both sides of the sandwiched projecting portion 61 of the rod-shaped body portion 31 are opened in a substantially semicircular shape so as to insert the wire 451 of the transmission member 45 and communicate with the space portion 7 of the rod-shaped body portion 31. In addition, the sandwiching protrusions 62 and 63 have space portions 621 and 631 that communicate with the space portion 7 and are open to the longitudinal end side of the rod-like body portion 32 in order to insert the wire 451 of the transmission member 45. Wall portions 622 and 632 for abutting and sandwiching the side surface of the sandwiched projecting portion 61 are provided. Thereby, the joint part 6 is relatively rotatable about the rotation shaft 64 with respect to the sandwiched projecting part 61 and the sandwiching projecting parts 62, 63.

そして、関節部６は、前記回転をロックするためのロック機構として、被挟持突出部６１に、被挟持突出部６１と挟持突出部６２、６３とが回転軸６４を中心に相対的に回転しても挟持突出部６２、６３とぶつかる突部や厚みを有しない、略４分の１円の扇形の平坦部分６６を形成し、平坦部分６６の所要の部位に当該平坦部分６６の厚み方向に延びる有底の孔部６７を円弧状に複数並ぶように設けている。   Then, the joint 6 functions as a locking mechanism for locking the rotation, and the sandwiched protrusion 61 and the sandwiched protrusions 62 and 63 rotate relative to each other around the rotation shaft 64. However, a fan-shaped flat portion 66 having a substantially quarter-circular shape that does not have a protrusion or thickness that collides with the sandwiching protrusions 62 and 63 is formed, and the flat portion 66 is formed at a required portion in the thickness direction of the flat portion 66. A plurality of bottomed holes 67 extending in a circular arc shape are provided.

但し、平坦部分６６の扇形状は略４分の１円に限定されず、これより面積に小さい略５分の１円や略６分の１円等としても、反対に面積の大きい略３分の１円や略半円としても良い。また、被挟持突出部６１はこの実施例では全体形状が扇形をなしているが、これに限定されず扇形の平坦部分６６を含む平板形状であれば良い。   However, the fan shape of the flat portion 66 is not limited to about a quarter of a circle. On the contrary, even if the area is about a fifth of a circle or about a sixth of a circle, the area is about three minutes. It may be 1 yen or a semi-circle. Moreover, although the to-be-clamped protrusion 61 has a sector shape as a whole in this embodiment, it is not limited to this and may be a flat plate shape including a sector-shaped flat portion 66.

孔部６７は、この実施例では、平坦部分６６が略４分の１円であることに対応して被挟持突出部６１と挟持突出部６２、６３とが同一軸線となる位置から被挟持突出部６１と挟持突出部６２、６３とが直角に交差する位置までの範囲において回転軸６４を中心点として１５度ずつずれて配置されており、その数は７つとなっている。   In this embodiment, the hole 67 is sandwiched and projected from a position where the sandwiched projecting portion 61 and the sandwiching projecting portions 62 and 63 are on the same axis corresponding to the flat portion 66 being approximately a quarter circle. In a range up to a position where the part 61 and the sandwiching projecting parts 62 and 63 intersect at right angles, the rotational axis 64 is displaced by 15 degrees from the center point, and the number thereof is seven.

そして、この実施例では、図５に示されるように、各孔部６７の近傍に９０°、７５°等の角度を示す数値が付けられており、孔部６７にロックピン６８を差し込んで被挟持突出部６１と挟持突出部６２、６３との交差角度を決定するときの目印となっている。   In this embodiment, as shown in FIG. 5, numerical values indicating angles of 90 °, 75 °, etc. are attached in the vicinity of each hole 67, and a lock pin 68 is inserted into the hole 67 to cover the hole 67. This is a mark for determining the crossing angle between the sandwiching protrusion 61 and the sandwiching protrusions 62 and 63.

また、関節部６は、前記ロック機構として、挟持突出部６２に、当該挟持突出部６２の厚み方向に延びると共に孔部６７の円弧状の並び方向と重なる位置に開口する貫通孔６５を設けている。   In addition, the joint portion 6 is provided with a through-hole 65 that extends in the thickness direction of the sandwiching protrusion 62 and opens in a position overlapping the arcuate arrangement direction of the holes 67 as the locking mechanism. Yes.

このようなロック機構の構成とすることにより、貫通孔６５側からロックピン６８を挿入して孔部６７にロックピン６８の先端を差し込むことで、被挟持突出部６１と挟持突出部６２、６３との交差する角度が所要に位置になったときに、関節部６の回転をロックすることが可能となっている。   With such a configuration of the lock mechanism, the pinching protrusion 61 and the pinching protrusions 62 and 63 are inserted by inserting the lock pin 68 from the through hole 65 side and inserting the tip of the lock pin 68 into the hole 67. It is possible to lock the rotation of the joint portion 6 when the angle intersecting with is at a required position.

しかるに、図２に示されるように、電柱等の障害物Ｐの反対側に対象物Ａが位置する場合でも、間接活線作業用工具１の共用部２の複数の関節部６を回転させて隣り合う棒状体部分３１〜３４を所要方向及び所要角度にて折り曲げて棒状体部分３１〜３４の軸線の向きを異ならせることにより、先端部１０の固定部材１０２と可動部材１０３とで対象物Ａを把持・挟持することが可能となる。   However, as shown in FIG. 2, even when the object A is located on the opposite side of the obstacle P such as a utility pole, the joint portions 6 of the shared portion 2 of the indirect live work tool 1 are rotated. The adjacent rod-like body portions 31 to 34 are bent at a required direction and a desired angle so that the directions of the axes of the rod-like body portions 31 to 34 are different, whereby the object A is fixed between the fixed member 102 and the movable member 103 of the distal end portion 10. Can be gripped and clamped.

そして、関節部６では、伝達部材４５のワイヤ４５１は、棒状体部分３１の空間部７を通って被挟持突出部６１の側方から棒状体部分３１の空間部７外に出た後、棒状体部分３２の挟持突出部６３の空間部６３１内に当該空間部６３１の開口部から入り、更に空間部６３１に連通した空間部７に至るようになっている。ここで、伝達部材４５のワイヤ４５１は、回転軸６４の軸棒と接する部位は、ワイヤ４５１が破損したり断線したりしないように筒状のカバー６９で保護されていることが望まれる。   Then, in the joint portion 6, the wire 451 of the transmission member 45 passes through the space portion 7 of the rod-shaped body portion 31 and goes out of the space portion 7 of the rod-shaped body portion 31 from the side of the sandwiched projecting portion 61. The space 631 of the sandwiching protrusion 63 of the body part 32 enters the space 631 from the opening of the space 631 and reaches the space 7 that communicates with the space 631. Here, it is desirable that the portion of the wire 451 of the transmission member 45 that is in contact with the shaft rod of the rotating shaft 64 is protected by a cylindrical cover 69 so that the wire 451 is not damaged or disconnected.
