Conventionally, in order to perform live line work (construction) of high-voltage overhead distribution lines safely and efficiently, a tool for indirect live line work such as a gripping tool at the tip of a pipe-shaped spindle with a required length ( (Hereinafter, sometimes referred to simply as a “tool”), and operating an operation unit composed of an operation lever or the like supported so as to be pivotable (swingable) on the grip portion on the rear end side of the main shaft. Therefore, an insulating operation rod for indirect live-line work (hereinafter sometimes simply referred to as “operation rod”) in which the tool at the tip is remotely operated via a connecting rod (link mechanism) is used. (For example, refer to Patent Documents 1 and 2).
JP-A-10-264056 JP 2000-102125 A

ところで、操作棒は、高圧の架空配電線等の活線での作業に使用されることから、作業者が感電することを防ぐ必要がある。そのため、先端部の工具からグリップ部までは一定長さ(安全限界距離)以上が必要となり、その分、全長が長くなる。   By the way, since the operation rod is used for work on a live wire such as a high-voltage overhead distribution line, it is necessary to prevent an operator from receiving an electric shock. For this reason, a certain length (safety limit distance) or more is required from the tool at the tip to the grip portion, and the total length is increased accordingly.

この長い操作棒を使用するためには、後端側のグリップ部を把持して操作棒を支持し、グリップ部の操作レバーを操作することで連結棒を介して先端部の工具が操作され、間接活線作業が行われる。その際、操作棒は、全長が長く、その後端部を片手のみで支持して作業を行うには手首にかなりの負担がかかってしまう。そのため、片手で長時間安定的に支持して作業できないという問題があった。   In order to use this long operation rod, the grip at the rear end side is gripped to support the operation rod, and the tool at the tip is operated via the connecting rod by operating the operation lever of the grip portion. Indirect hot-line work is performed. At that time, the operating rod has a long overall length, and it takes a considerable burden on the wrist to support the rear end portion with only one hand. For this reason, there is a problem that it is impossible to work stably with one hand for a long time.

そこで、本発明は、手首の負担を軽減し、片手で長時間安定的に支持して作業できる操作棒を提供することを課題とする。   Therefore, an object of the present invention is to provide an operation rod that can reduce the burden on the wrist and can be stably supported and operated with one hand for a long time.

上記課題を解決するために、本発明に係る間接活線作業用絶縁操作棒は、先端部に工具が設けられる主軸と、前記主軸の後端側のグリップ部とを備える間接活線作業用絶縁操作棒であって、前記グリップ部の後端部に、腕に固定するための固定手段が設けられることを特徴とする。   In order to solve the above-mentioned problems, an indirect hot-wire work insulation operating rod according to the present invention comprises a main shaft provided with a tool at a tip portion and a grip portion on the rear end side of the main shaft. The operation rod is characterized in that a fixing means for fixing to the arm is provided at a rear end portion of the grip portion.

上記構成とすることで、手でグリップ部を把持する以外に固定手段によって腕に固定されることから、操作棒の重量を、把持している手と固定手段で固定されている腕の部分との2箇所に分散することができるようになる。   By adopting the above configuration, since the grip portion is fixed to the arm by the fixing means in addition to gripping the grip portion by hand, the weight of the operating rod is determined by the gripping hand and the portion of the arm fixed by the fixing means. It becomes possible to disperse in two places.

また、前記グリップ部の前記固定手段より先端側に前記主軸と直交する方向のサイドバーがさらに設けられる構成とすることが好ましい。   In addition, it is preferable that a side bar in a direction orthogonal to the main shaft is further provided on the tip side of the fixing means of the grip portion.

上記構成とすることで、主軸に沿ったグリップ部を把持する際のように手首を曲げる必要がなくなるため、手首への負担が少なくなる。その結果、長時間の作業を安定して行うことができるようになる。また、主軸の軸芯を中心に回転させるような作業を行う際に、主軸と直交するサイドバーを把持して操作棒を回転させた方が、主軸に沿ったグリップ部を把持して回転させるよりも手首への負担が少なく、且つより大きな(強い)トルクを与えることができるようになる。   By adopting the above configuration, it is not necessary to bend the wrist as in gripping the grip portion along the main axis, so the burden on the wrist is reduced. As a result, long-time work can be stably performed. Also, when performing operations that rotate around the axis of the main shaft, the side bar that is orthogonal to the main shaft is gripped and the operating bar is rotated to grip and rotate the grip portion along the main shaft. As a result, the wrist is less burdened and a larger (strong) torque can be applied.

また、前記固定手段のさらに後端側に、腕の付け根に当接させて支持するための肩当て部がさらに設けられる構成とすることが好ましい。   In addition, it is preferable that a shoulder pad portion is further provided on the rear end side of the fixing means so as to contact and support the base of the arm.

上記構成とすることで、操作棒の先端を上方に向けて作業する際に、操作棒の重量が腕の付け根にも分散されるため、より手首や腕への負担を減らすことができ、長時間の作業を行うことができるようになる。   With the above configuration, when working with the tip of the operating rod facing upward, the weight of the operating rod is also distributed to the base of the arm, which can further reduce the burden on the wrist and arm. You will be able to do time work.

また、リンク機構がさらに設けられ、且つ前記リンク機構を介して前記工具の操作を行う操作部が前記グリップ部の先端部にさらに設けられる構成としても良い。   Moreover, it is good also as a structure by which a link mechanism is further provided and the operation part which operates the said tool via the said link mechanism is further provided in the front-end | tip part of the said grip part.

上記構成とすることで、主軸の先端部に可動式工具を取り付けることができるようになり、行える作業の種類が多くなる。   With the above configuration, the movable tool can be attached to the tip of the spindle, and the types of work that can be performed increase.

また、前記工具は、主軸の先端部に対して着脱可能に構成されても良い。   Moreover, the said tool may be comprised so that attachment or detachment with respect to the front-end | tip part of a main axis | shaft is possible.

上記構成とすることで、先端部の工具を取り替えることで、一本の間接活線作業用絶縁操作棒でさらに多くの作業を行えるようになる。従って、高所での作業時に多くの間接活線作業用絶縁操作棒を携帯する必要がなくなるため、作業が行い易くなる。   With the above-described configuration, by replacing the tool at the tip, more work can be performed with a single indirect hot-wire work insulating operation rod. Accordingly, it is not necessary to carry a large number of indirect hot-wire work insulating operation rods when working at a high place, and the work becomes easier.

また、主軸と、その先端部に設けられる把持具と、前記主軸の後端側のグリップ部と、前記主軸に沿って設けられるリンク機構と、前記グリップ部の先端部に設けられ且つ前記リンク機構を介して前記把持具の開閉操作を行う操作レバーと、前記操作レバーよりも後端側近傍且つ主軸と直交する方向に設けられるサイドバーと、前記サイドバーよりも後端側に設けられる腕に固定するための固定手段とを備える間接活線作業用絶縁操作棒であって、前記リンク機構が伸縮可能に構成され、且つこの伸縮に伴い、前記操作レバーの姿勢を前記サイドバーに対する操作レバーの接離によって先端部の把持具の前記操作を行う第1姿勢と、前記グリップ部に対する操作レバーの接離によって先端部の把持具の前記操作を行う第2姿勢とに切り替え可能とする構成としても良い。   The main shaft, a gripping tool provided at the front end portion thereof, a grip portion on the rear end side of the main shaft, a link mechanism provided along the main shaft, and provided at the front end portion of the grip portion and the link mechanism An operation lever that opens and closes the gripper via a side bar, a side bar that is provided in the vicinity of the rear end side of the operation lever and in a direction perpendicular to the main axis, and an arm that is provided on the rear end side of the side bar.

It may be configured to be.

上記構成とすることで、サイドバーを取り付け、該サイドバーに対する操作レバーの接離によって把持具の操作を行う手首に負担のかからない状態での操作棒を使用した作業と、サイドバーを操作レバーと干渉しない状態(例えば、取り外した状態、折り畳んだ状態)にし、グリップ部に対する操作レバーの接離によって把持具の操作を行う従前からの手首を曲げた状態での作業との両方のタイプの作業を行えるようになるため、より種々な状況での使用が可能となる。   With the above-described configuration, the sidebar is attached to the sidebar, the operation using the operation bar in a state where the wrist is not burdened, and the sidebar is operated with the operation lever. Do not interfere (for example, removed or folded), and operate the gripping tool by moving the operating lever to and from the grip part. Since it becomes possible, it can be used in more various situations.

以上のように、本発明によれば、手首の負担を軽減し、間接活線作業用絶縁操作棒を片手で長時間安定的に支持して作業が行えるようになる。   As described above, according to the present invention, it is possible to reduce the burden on the wrist and to perform the work while stably supporting the insulating operation rod for indirect hot-line work with one hand for a long time.

In this embodiment, the anti-slip member can be replaced, but it may be attached to the surface of the main shaft 10 and not replaceable.

固定バンド60は、図3に示す如く、グリップ部50の後端側に主軸10と直交する方向に着脱可能に取り付けられ、環状のバンド部61と、該バンド部61をグリップ部50(主軸1)に固定するための固定具62とを備える。   As shown in FIG. 3, the fixed band 60 is detachably attached to the rear end side of the grip portion 50 in a direction perpendicular to the main shaft 10, and the annular band portion 61 and the band portion 61 are connected to the grip portion 50 (the main shaft 1). ) And a fixing tool 62 for fixing.

バンド部61は、一端に柔軟性を有する帯状バンド63が取り付けられ、他端に環状のガイド64が取り付けられた、帯状バンド63とほぼ同幅で弾性を有する帯状体を半円形状に湾曲させたものである。帯状バンド63は、先端部表面に面ファスナーの雄部材65が設けられており、同一面の後方側には面ファスナーの雌部材66が設けられている。この帯状バンド63の先端をガイド64に挿通させて矢印D方向に折り返し、先端部に設けられた面ファスナーの雄部材65を後方側に設けられた面ファスナーの雌部材66に係止させる。こうすることでバンド部61は環状となり、帯状バンド63の先端部を係止する位置を変えることによって、バンド部61の径を調節することができる。   The band portion 61 has a flexible belt-like band 63 attached to one end and an annular guide 64 attached to the other end, and is curved in a semicircular shape with a width approximately the same as the belt-like band 63 and having elasticity. It is a thing. The belt-like band 63 is provided with a male member 65 of a hook-and-loop fastener on the front surface, and a female member 66 of a hook-and-loop fastener on the rear side of the same surface. The front end of the belt-like band 63 is inserted into the guide 64 and folded back in the direction of the arrow D, and the male member 65 of the hook-and-loop fastener provided at the tip is engaged with the female member 66 of the hook-and-loop fastener provided on the rear side. By doing so, the band portion 61 becomes an annular shape, and the diameter of the band portion 61 can be adjusted by changing the position where the front end portion of the band-like band 63 is locked.

固定具62は、帯状弾性体を湾曲させて略C字状に形成し、バンド部61とは互いに接している面と垂直な軸を中心にして互いに回動可能に連結されている。固定具62は、その両端部を外側に屈曲させ、この屈曲部の対向する位置にはそれぞれ穴67,68が設けられている。片方の穴68には、内周面に雌ネジが螺刻されている。そして、締め付けネジ69が穴67を挿通して穴68に螺入される。この時、穴67の径は、締め付けネジ69の雄ネジ部の径よりもわずかに大きく且つ頭部の径よりも小さく設定されている。従って、締め付けネジ69を軸芯を中心に回転させると、穴68が設けられた屈曲部が穴67の設けられた屈曲部に接近又は離間して固定具62の径が変化する。従って、この固定具62にグリップ部50(主軸10)を挿入して締め付けネジ69を締め付けることにより、固定バンド60をグリップ部50の任意の位置に固定することができる。   The fixture 62 is formed in a substantially C shape by curving the belt-like elastic body, and is connected to the band portion 61 so as to be rotatable around an axis perpendicular to the surface in contact with each other. Both ends of the fixing device 62 are bent outward, and holes 67 and 68 are provided at positions facing the bent portions, respectively. In one hole 68, an internal thread is threaded on the inner peripheral surface. Then, the tightening screw 69 is inserted into the hole 68 through the hole 67. At this time, the diameter of the hole 67 is set to be slightly larger than the diameter of the male screw portion of the tightening screw 69 and smaller than the diameter of the head. Therefore, when the tightening screw 69 is rotated about the axis, the bent portion provided with the hole 68 approaches or separates from the bent portion provided with the hole 67, and the diameter of the fixture 62 changes. Therefore, the fixing band 60 can be fixed at an arbitrary position of the grip portion 50 by inserting the grip portion 50 (the main shaft 10) into the fixture 62 and tightening the tightening screw 69.

図1に戻って、肩当て部70は、操作棒1の後端に設けられており、より詳しくは、後述する伸長部80の後端へ伸長軸81の軸芯を中心に回動可能に設けられている。肩当て部70は、腕の付け根に当接させて主軸10(操作棒1)を支持し易くするための部分であることから、腕の付け根の形状に沿った一定幅の円弧状に形成されている。   Returning to FIG. 1, the shoulder rest 70 is provided at the rear end of the operation rod 1, and more specifically, can be rotated around the axis of the extension shaft 81 to the rear end of the extension 80 described later. Is provided. The shoulder rest portion 70 is a portion for making it easy to support the main shaft 10 (the operating rod 1) by contacting the base of the arm, and is thus formed in an arc shape with a constant width along the shape of the base of the arm. ing.

伸長部80は、前記連結棒13に形成された伸長部15と同様の構成であり、主軸10に出し入れ自在に内挿される棒状の伸長軸81と、締め付けネジ82とで構成される。そして、前期同様に締め付けネジ82を回転させることによって、伸長軸81を主軸10から必要な長さだけ送出した状態で固定でき、反対方向に回転させることで伸長軸81の固定状態が解放される。また、伸長軸81は、その後端部に肩当て部70が着脱可能に取り付けられる。この肩当て部70を取り外した場合には、伸長軸81の後端部にはゴムキャップ83(図4参照)が取り付けられる。   The extending portion 80 has the same configuration as that of the extending portion 15 formed on the connecting rod 13, and includes a rod-shaped extending shaft 81 that is inserted into and removed from the main shaft 10 and a fastening screw 82. Then, by rotating the tightening screw 82 in the same manner as in the previous period, the extension shaft 81 can be fixed in a state where it has been delivered from the main shaft 10 by a required length, and by rotating in the opposite direction, the fixed state of the extension shaft 81 is released. . In addition, the shoulder shaft 70 is detachably attached to the rear end portion of the extension shaft 81. When the shoulder rest 70 is removed, a rubber cap 83 (see FIG. 4) is attached to the rear end of the extension shaft 81.

以上が、操作棒1の構成であり、次にその使用方法を説明する。   The above is the configuration of the operation rod 1, and how to use it will now be described.

環状のバンド部61に腕を通した状態にして、帯状バンド63の先端部の係止位置を調整してバンド部61を締め付けて腕(肘より少し手先側部分)に固定する。この固定された方の手でサイドバー40及び操作レバー31を一緒に把持する。その後、肩当て部70が、固定された方の腕の付け根前方側に当接するように伸長部80で調整する。この状態で、サイドバー40及び操作レバー31をさらに握り込む。そうすると操作レバー31は、図1の矢印A方向に回動して、連結棒13が矢印B方向に引き下げられる。その結果、回動把持片22が枢着ピン24を中心にして矢印C方向に回動して固定把持片21の先端と回動把持片12の先端とが接近して把持具20は閉じ、被把持物を把持する。一方、操作レバー31を矢印Aと反対方向に回動させると、連結棒13は、矢印Bと反対方向に押し上げられ、回動把持片12は、矢印Cと反対方向に回動して、被把持物を離す。   The arm is passed through the annular band portion 61, the locking position of the end portion of the band-shaped band 63 is adjusted, and the band portion 61 is tightened to fix it to the arm (the hand side portion slightly from the elbow). The side bar 40 and the operation lever 31 are held together with the fixed hand. After that, the extension part 80 adjusts so that the shoulder rest part 70 comes into contact with the base front side of the fixed arm. In this state, the side bar 40 and the operation lever 31 are further grasped. Then, the operation lever 31 rotates in the direction of arrow A in FIG. 1 and the connecting rod 13 is pulled down in the direction of arrow B. As a result, the rotating gripping piece 22 rotates around the pivot pin 24 in the direction of the arrow C, the tip of the fixed gripping piece 21 and the tip of the rotating gripping piece 12 approach, and the gripping tool 20 is closed. Hold the object to be gripped. On the other hand, when the operation lever 31 is rotated in the direction opposite to the arrow A, the connecting rod 13 is pushed up in the direction opposite to the arrow B, and the rotary gripping piece 12 is rotated in the direction opposite to the arrow C to be covered. Release the object.

また、図4に示す如く、操作棒1に着脱可能に設けられているサイドバー40、固定バンド60及び肩当て部70を取り外す。次に、連結棒13後端部の伸長部15における締め付けネジ17を緩め、伸長軸16を連結棒13から送出する。このようにすることで、操作レバー31の先端がグリップ部50と接近する。即ち、操作レバー31とグリップ部50とのなす角αが小さくなる。この状態で締め付けネジ17を締め付け、伸長軸16を固定する。そうすると、従前からの両手で支持して作業する操作棒と同様の構成となり、従前の操作棒同様の使用が可能となる。   Moreover, as shown in FIG. 4, the side bar 40, the fixing band 60, and the shoulder rest part 70 which are provided in the operation rod 1 so that attachment or detachment is possible are removed. Next, the tightening screw 17 in the extending portion 15 at the rear end portion of the connecting rod 13 is loosened, and the extending shaft 16 is delivered from the connecting rod 13. By doing so, the tip of the operation lever 31 approaches the grip portion 50. That is, the angle α formed between the operation lever 31 and the grip portion 50 is reduced. In this state, the fastening screw 17 is fastened to fix the extension shaft 16. If it does so, it will become the structure similar to the operation rod which supports and works with both hands from before, and the same use as a conventional operation rod will be attained.

以上のように使用されるが、操作棒1は、固定バンド60によって腕に固定されているため、サイドバー40と固定バンド60の2箇所で支持されることから重量が分散され、片手で長時間安定的に支持して作業できるようになる。   Although it is used as described above, since the operating rod 1 is fixed to the arm by the fixing band 60, the weight is dispersed because it is supported at two places of the side bar 40 and the fixing band 60, and it is long with one hand. It will be possible to work with stable support over time.

また、サイドバー40が主軸10と直交する方向に設けられているため、主軸10に沿ったグリップ部50を把持する時よりも手首を曲げなくて良いため手首への負担が少なくなる。そのため、長時間の作業を行っても手首への負担が少なくて済む。   Further, since the side bar 40 is provided in a direction orthogonal to the main shaft 10, it is not necessary to bend the wrist as compared with the case of gripping the grip portion 50 along the main shaft 10, so that the burden on the wrist is reduced. Therefore, the burden on the wrist can be reduced even when working for a long time.

また、操作棒1を軸芯を中心に回転させる動作を行う際、グリップ部50を把持して回転させるよりも、主軸10と直交する方向に設けられているサイドバー40を把持して回転させた方が、手首への負担が少なく且つより強いトルクを与えることができるようになる。また、回転させた状態で維持する際にも、手首にかかる負担が極めて少ないため長時間の作業が可能となる。   Further, when the operation rod 1 is rotated around the axis, the side bar 40 provided in the direction perpendicular to the main shaft 10 is gripped and rotated rather than the grip portion 50 is gripped and rotated. Thus, the burden on the wrist is less and a stronger torque can be applied. Also, when maintaining the state in a rotated state, the burden on the wrist is extremely small, so that a long time operation is possible.

さらに、肩当て部70が操作棒1の後端部に設けられていることから、操作棒1の先端を上に向けての作業を行う際に、操作棒1の重量がサイドバー40を把持する手、バンド部61で固定されている腕及び肩当て部70が当接している腕の付け根部に分散されるため、長時間の安定した作業を行うことができるようになる。   Further, since the shoulder rest 70 is provided at the rear end of the operation rod 1, the weight of the operation rod 1 grips the side bar 40 when the operation rod 1 is operated with the front end facing upward. The arm fixed to the hand, the arm fixed by the band unit 61, and the base of the arm against which the shoulder pad 70 abuts are dispersed, so that stable work for a long time can be performed.

尚、本発明は、上記実施形態のみに限定されるものではなく、本発明の要旨を逸脱しない範囲での種々の変更は可能である。   In addition, this invention is not limited only to the said embodiment, A various change in the range which does not deviate from the summary of this invention is possible.

例えば、本実施形態においては、サイドバー40は、固定具43によって着脱可能に構成されているが、固定具43が固定バンド60における固定具62のような構成であっても良く、グリップ部50に直接ネジ止等の他の方法によって固定しても良い。また、可倒式のサイドバーにしても良い。   For example, in the present embodiment, the side bar 40 is configured to be detachable by the fixing tool 43, but the fixing tool 43 may be configured like the fixing tool 62 in the fixing band 60, and the grip portion 50. It may be fixed directly by other methods such as screwing. Also, it may be a retractable sidebar.

また、本実施形態においては、往復動する動力を伝達するリンク機構(連結棒13)が備えられているが、回転動力を伝達するリンク機構を備えても良い。その場合、操作部30には支持ピン34を中心に一定角度内を回動(揺動)する操作レバー31ではなく、360°回動可能な操作レバーを設けても良い。   Moreover, in this embodiment, although the link mechanism (connecting rod 13) which transmits the power which reciprocates is provided, you may provide the link mechanism which transmits rotational power. In this case, the operation unit 30 may be provided with an operation lever that can rotate 360 ° instead of the operation lever 31 that rotates (swings) within a certain angle around the support pin 34.

また、動力を伝達するリンク機構(連結棒13)及び操作レバー31を備えず、且つ主軸10の先端には把持具20ではなくフック状のもの(所謂トング等)が備えられても良い。このような構成であっても、サイドバー40が設けられていれば、主軸10の軸芯を中心に回転させる作業は行い易く、且つ手首への負担が少ない。また、固定バンド60及び肩当て部70が設けられていれば、操作棒1の重量を分散させることができ、腕への負担が減り、長時間安定した作業を行うことができるようになる。   Further, the link mechanism (the connecting rod 13) for transmitting power and the operation lever 31 may not be provided, and the tip of the main shaft 10 may be provided with a hook-like object (a so-called tongue or the like) instead of the gripping tool 20. Even in such a configuration, if the side bar 40 is provided, it is easy to perform the operation of rotating around the axis of the main shaft 10 and the burden on the wrist is small. Further, if the fixing band 60 and the shoulder pad 70 are provided, the weight of the operation rod 1 can be dispersed, the burden on the arm is reduced, and stable work can be performed for a long time.

また、把持具20の固定把持片21と回動把持片22とは、両方が一本の把持片である必要はなく、一方の把持片が二股に形成されると共に他方の把持片が一本に形成され、且つ二股の把持片の先端部間に一本の把持片の先端部が入るように回動する構成であっても良い。   Further, the fixed gripping piece 21 and the rotating gripping piece 22 of the gripping tool 20 do not have to be one gripping piece. One gripping piece is formed in a fork and the other gripping piece is one. It is also possible to have a configuration in which the tip end of one gripping piece is inserted between the tip end portions of the forked gripping piece.

また、本実施形態においては、固定部60は、バンド部61と固定具62とが分離不可能に連結されているが、バンド部61と固定具62とは分離可能であっても良い。このような構成とすることで、バンド部61を腕に装着した後に、グリップ部50に固定した固定具62にバンド部61を係止すれば、腕に操作棒1を固定し易くなる。   Moreover, in this embodiment, although the fixing | fixed part 60 has connected the band part 61 and the fixing tool 62 so that separation is not possible, the band part 61 and the fixing tool 62 may be separable. With such a configuration, if the band portion 61 is locked to the fixture 62 fixed to the grip portion 50 after the band portion 61 is attached to the arm, the operation rod 1 can be easily fixed to the arm.

さらには、固定部60は、腕に操作棒1を着脱可能に固定できれば良いことから、ひも状体で構成されても良く、フック状体で構成されても良い。   Furthermore, since the fixing part 60 should just be able to detachably fix the operation stick 1 to an arm, it may be comprised by a string-like body and may be comprised by a hook-like body.
