Description

本発明は、間接活線工具の先端に取り付け可能な間接活線用先端工具に関する。   The present invention relates to a tip tool for indirect hot wire that can be attached to the tip of an indirect hot wire tool.

間接活線作業においては、間接活線工具を使用して作業しており、例えば、防護用絶縁シート等の部材や所定の器具等を把持するために、棒状の先端部に把持部が設けられ他端にこの把持部の開閉を操作する操作部有するヤットコを使用している(特許文献1参照)。   In indirect hot wire work, an indirect hot wire tool is used.For example, in order to hold a member such as a protective insulating sheet or a predetermined instrument, a grip portion is provided at a rod-shaped tip. A Yatco having an operation part for operating opening and closing of the gripping part is used at the other end (see Patent Document 1).

また、ヤットコで径が細い引下線等を把持しようとすると、把持部から引下線が外れたりして把持しにくいため、把持部の一方が二股に形成され、他方の把持部の先端が閉じたときに二股の間に挿通するように形成されたクイックを使用している(特許文献2参照)。
このように、間接活線作業では把持対象物によって間接活線工具を使い分けている。
In addition, if you try to grip a pull line with a thin diameter with a Yatco, the pull line will come off from the grip part and it will be difficult to grip, so one of the grip parts will be formed in two and the tip of the other grip part will be closed Sometimes a quick formed so as to be inserted between two forks is used (see Patent Document 2).
As described above, in the indirect live line work, the indirect live line tool is properly used depending on the object to be grasped.

特開2012―060703号公報JP 2012-060703 A 特開2012―161198号公報JP 2012-161198 A

しかしながら、上述のとおり、ヤットコは細い径の把持対象物の把持には不向きであり、クイックは電線のような細い径の把持対象物にしか使用できないため、作業内容によってヤットコとクイックとを適宜持ち替えて作業しなければならず、作業性が悪い問題がある。   However, as mentioned above, Yatco is unsuitable for gripping objects with a small diameter, and Quick can only be used for objects with a small diameter such as electric wires. There is a problem that workability is poor.

また、ヤットコやクイックでは、ピン碍子の碍子部分のような太径のものを把持しようとすると、把持部を開いたときの先端同士の距離が碍子部分の直径よりも短かったり、把持部の先端から回動軸までの距離が碍子部分の半径よりも短かったりするために、碍子部分の中心を挟んだ両側面を把持部が把持することができない。   Also, with Yatco or Quick, when trying to grip a large-diameter object such as a lever part of a pin insulator, the distance between the tips when the grip part is opened is shorter than the diameter of the insulator part, or the tip of the grip part Since the distance from the rotation axis to the rotation axis is shorter than the radius of the lever portion, the gripping portion cannot hold both side surfaces sandwiching the center of the lever portion.

このため、把持部が碍子部分から滑って安定した把持ができずにピン碍子が落下する恐れがあり、落下によりピン碍子が破損したり、落下したピン碍子に当たった材料が破損したり、落下したピン碍子に作業者が当たって怪我をしたりする恐れもある。
したがって、ヤットコやクイックから作業に見合った別の間接活線作業用工具に持ち替えて作業しなければならず、作業が煩雑になり作業時間が延びる問題もある。
For this reason, the gripping part may slip from the insulator part and the pin insulator may fall without stable gripping, and the pin insulator may be damaged due to the fall, or the material hit the dropped pin insulator may be damaged or dropped. There is also a risk that an operator may hit the pin insulator and get injured.
Therefore, the work must be changed from Yatco or Quick to another indirect hot-line work tool suitable for the work, which causes a problem that the work becomes complicated and the work time is extended.

本発明は、かかる事情に鑑みてなされたものであり、複数の種類の間接活線用先端工具を使用せずに1つの間接活線用先端工具で作業することが可能な間接活線用先端工具を提供することを主たる課題としている。   The present invention has been made in view of such circumstances, and an indirect live wire tip capable of working with one indirect live wire tip tool without using a plurality of types of indirect live wire tip tools. The main challenge is to provide tools.

上記課題を達成するために、本発明に係る間接活線用先端工具は、間接活線工具の可動側の先端部に取り付け可能に形成された第1の把持片と、前記間接活線工具の固定側の先端部に取り付け可能に形成された第2の把持片と、によって構成される間接活線用先端工具において、前記第1の把持片及び第2の把持片は、間接活線工具の先端部に取り付け可能に形成された接続部と、前記接続部に続いて形成された爪部と、を有し、前記爪部は、先端方向に延出して形成された棒状部を有し、前記間接活線工具を開いたときの前記第1の把持片と第2の把持片間の距離は、把持対象物の最大幅よりも長く形成され、前記棒状部の長さは、前記把持対象物の最大幅の半分の長さを少なくとも有し、前記第2の把持片は、前記第1の把持片よりも把持方向の幅が広く形成され、前記第1の把持片には、n本(nは2以上の整数)の棒状部が一体に形成され、前記第2の把持片には、n+1本の棒状部が一体にして形成され、前記第1の把持片及び前記第2の把持片のそれぞれの爪部の隣り合う棒状部間には隙間が形成され、前記間接活線工具を閉じたときに、一方の把持片の前記隙間に他方の把持片の前記棒状部が挿通して、両把持片が交差することを特徴としている。 In order to achieve the above object, an indirect live wire tip tool according to the present invention includes a first gripping piece that is attachable to a movable tip portion of an indirect live wire tool, and the indirect live wire tool. In the indirect live wire tip tool constituted by the second grip piece formed to be attachable to the fixed-side tip portion, the first grip piece and the second grip piece are the indirect live tool. A connecting portion formed so as to be attachable to the distal end portion, and a claw portion formed subsequent to the connecting portion, the claw portion having a rod-like portion formed extending in the distal end direction, The distance between the first gripping piece and the second gripping piece when the indirect live tool is opened is longer than the maximum width of the gripping object, and the length of the rod-shaped portion is the gripping target. at least a half length of the maximum width of the object, the second gripping piece, the bunch than the first gripping piece The first gripping piece is integrally formed with n (n is an integer of 2 or more) rod-like portions, and the second gripping piece has n + 1 rod-like portions. There are formed so as to be integrated, the gap is formed between the first gripping piece and the second rod-shaped portion adjacent the respective claw portions of the gripping piece, when closing the indirect hot tool, whereas The rod-shaped part of the other gripping piece is inserted into the gap of the gripping piece, and the gripping pieces intersect each other.

間接活線工具を開いたときの第1の把持片と第2の把持片間の距離は、把持対象物の最大幅よりも長く形成され、爪部は、先端方向に延出して形成された棒状部を有し、棒状部の長さは、前記把持対象物の最大幅の半分の長さを少なくとも有し、第1又は第2の把持片の少なくともいずれか一方の前記爪部に隙間が形成され、間接活線工具を閉じたときに、前記隙間に他方の把持片の爪部の先端が挿通して、両把持片が交差することで、ピン碍子の碍子部分のような太径のものについては、把持対象物の重心を挟んだ両側面を把持部が把持することができ、また、引下線のような細径のものについては、隙間と棒状部の先端との間に把持対象物を挟み込んで把持することができるため、複数の間接活線工具を用いずに把持対象物を安定的に把持することが可能となる。
第2の把持片は、第1の把持片よりも把持方向の幅が広く形成され、隙間が第2の把持片の爪部に形成されることで、間接活線先端工具の固定側をより広い面積で把持対象物支えることが可能となるため、より安定した把持が可能となる。
隙間が棒状部間に形成されることで、間接活線用先端工具の軽量化を図ることが可能となり、作業時の作業者の疲労を軽減することが可能となる。
隙間は、第1の把持片及び第2の把持片の爪部に形成され、前記第2の把持片の爪部は、少なくとも2箇所以上に隙間が形成されることで、少なくとも第1の把持片の爪部に2本の棒状部と、第2の把持片の爪部に3本の棒状部を有することになり、ピン碍子の碍子部分のような太径かつ重量があるものをより広い面積で把持することが可能になるため、安定して把持することが可能となる。
The distance between the first gripping piece and the second gripping piece when the indirect hot wire tool is opened is formed to be longer than the maximum width of the gripping object, and the claw portion is formed to extend in the tip direction. It has a rod-like portion, the length of the rod-like portion is at least half the maximum width of the grasped object, and there is a gap in at least one of the claw portions of the first or second grasping piece. When the indirect live tool is formed and the tip of the claw part of the other gripping piece is inserted into the gap and the gripping pieces intersect, the large diameter of the pin insulator like the lever part For objects, the gripping part can grip both side surfaces sandwiching the center of gravity of the object to be grasped, and for objects with a small diameter such as an underline, the object to be grasped is between the gap and the tip of the bar-shaped part. Since the object can be sandwiched and gripped, the object to be gripped can be grasped stably without using multiple indirect hot-line tools. It is possible to become.
The second gripping piece is formed wider in the gripping direction than the first gripping piece, and the gap is formed in the claw portion of the second gripping piece so that the fixed side of the indirect live wire tip tool is more Since the object to be grasped can be supported in a wide area, more stable grasping is possible.
By forming the gap between the rod-shaped portions, it is possible to reduce the weight of the indirect live wire tip tool, and to reduce the fatigue of the operator during the work.
The gap is formed in the claw portions of the first gripping piece and the second gripping piece, and the claw portion of the second gripping piece is formed with at least two gaps so that at least the first gripping piece is formed. It has two bar-shaped parts on the claw part of the piece and three bar-shaped parts on the claw part of the second gripping piece, and a wider one having a large diameter and weight like a lever part of the pin insulator. Since it becomes possible to hold by area, it becomes possible to hold stably.

第1の把持片には、2本の棒状部が一体に形成され、前記第2の把持片には、3本の棒状部が一体にして形成されるようにしてもよい。Two rod-shaped portions may be integrally formed on the first grip piece, and three rod-shaped portions may be integrally formed on the second grip piece.

前記棒状部は、前記間接活線用工具を最大限に開いたときに円筒状の把持対象物の側面に沿うように把持方向の内側に湾曲し、かつ、その長さが前記把持対象物の半径よりも長く形成されるようにしてもよい。
棒状部は、把持方向の内側に湾曲して形成されることで、円筒状に形成された把持対象の側面に沿って把持することができるため、安定して把持することができるため、把持対象物が落下することを防止することが可能となる。
The rod-shaped portion is curved inward in the gripping direction so as to follow the side surface of the cylindrical gripping object when the indirect live tool is opened to the maximum, and the length of the rod-shaped part is the length of the gripping object. It may be formed longer than the radius.
Since the rod-shaped portion is formed to be curved inward in the gripping direction and can be gripped along the side surface of the gripping target formed in a cylindrical shape, it can be stably gripped. It becomes possible to prevent an object from falling.

以上述べたように、本発明の間接活線用先端工具によれば、間接活線工具を開いたときの第1の把持片と第2の把持片間の距離は、把持対象物の最大幅よりも長く形成され、爪部は、先端方向に延出して形成された棒状部を有し、棒状部の長さは、前記把持対象物の最大幅の半分の長さを少なくとも有し、第1又は第2の把持片の少なくともいずれか一方の前記爪部に隙間が形成され、間接活線工具を閉じたときに、前記隙間に他方の把持片の爪部の先端が挿通して、両把持片が交差することで、ピン碍子の碍子部分のような太径のものについては、把持対象物の重心を挟んだ両側面を把持部が把持することができ、また、引下線のような細径のものについては、隙間に棒状部の先端を挿通させて把持対象物を挟み込むことで把持することができるため、複数の間接活線工具を用いずに把持対象物を安定的に把持することが可能となる。   As described above, according to the indirect live tool tip of the present invention, the distance between the first gripping piece and the second gripping piece when the indirect live tool is opened is the maximum width of the gripping object. The claw portion has a rod-like portion formed extending in the distal direction, and the length of the rod-like portion is at least half the maximum width of the grasped object, When a gap is formed in at least one of the claw portions of the first or second gripping piece and the indirect live tool is closed, the tip of the claw portion of the other gripping piece is inserted into the gap, and both As the gripping piece intersects, the gripping part can grip both sides of the center of gravity of the object to be gripped, such as the lever part of the pin insulator, For small diameters, it can be gripped by inserting the tip of the rod-shaped part into the gap and sandwiching the object to be gripped. Kill Therefore, it is possible to grasp stably grasped object without using a plurality of indirect hot tool.

このため、クイックとヤットコの両方の工具を準備したり、クイックとヤットコを使い分けたりする必要がなくなるため、作業時間の短縮を図ることが可能となり、必要な間接活線工具も最小限になるためより広い作業スペースを確保することが可能となる。   This eliminates the need to prepare both Quick and Yatco tools or to use both Quick and Yatco properly, thus reducing work time and minimizing the necessary indirect hot-line tools. A wider working space can be secured.
