Description

本発明は、鋼心アルミ撚り線等、複数の導線(素線)を撚り合わせてなる電線のばらけを防止する治具に関し、特に、2本の電線の端部をスリーブにて圧縮接続する際、或いは1本の電線を切断する場合等に、電線を強固に締め付けることにより、撚り合わされた導線の撚りが緩んでばらけることを防止するばらけ防止具に関する。   The present invention relates to a jig for preventing the breakage of electric wires formed by twisting a plurality of conducting wires (element wires) such as a steel core aluminum stranded wire, and in particular, compressively connect the ends of two electric wires with a sleeve. In particular, the present invention relates to an anti-scattering tool that prevents a twist of a twisted conductor from being loosened and loosened by firmly tightening the electric wire when, for example, cutting one electric wire.

架空送電線には、鋼心アルミ撚り線等、複数の導線(素線)を撚り合わせてなる電線が用いられている。
このような2本の電線の端部同士を、接続スリーブを用いて圧縮接続する場合には、接続スリーブの各開口端から接続スリーブ内に各電線の端部を夫々挿入し、電線を接続スリーブごと圧縮して接続する。圧縮接続の際には、接続スリーブの圧縮伸びにより素線を接続スリーブ外に押し出すような力が働く。その結果、接続スリーブに近接した部位の素線の撚りが緩んでばらける「笑い」現象が生じる。
素線のばらけた電線は、抵抗値の増大やこれに伴う異常加熱、或いは雨水の浸入による素線の腐食等、様々な問題を引き起こすため、電線の圧縮接続時には素線がばらけないようにする必要がある。
従来は、接続スリーブ近傍の電線部分にバインド線やゴムチューブ等を人力により強固に巻き付けて素線がばらけないようにしていた。しかし、人力による作業では締め付け力が不足する場合があり、素線がばらけることを完全には防止できない。
ここで、特許文献1には、圧縮接続箇所の電線を水平に保持するための電線スリーブ圧縮補助具が記載されている。この補助具は、電線を動かないように把持する把持クリップを備えている。把持クリップによって把持された電線は、圧縮接続時に長手方向に移動することも、電線の中心軸周りに回転することも阻止されるので、効果的に素線のばらけを防止できる。
As the overhead power transmission line, an electric wire formed by twisting a plurality of conductive wires (element wires) such as a steel core aluminum stranded wire is used.
When compressing and connecting the ends of two electric wires using a connection sleeve, the ends of the electric wires are inserted into the connection sleeve from the open ends of the connection sleeve, and the electric wires are connected to the connection sleeve. Compress each and connect. At the time of compression connection, a force that pushes the strands out of the connection sleeve works due to the compression elongation of the connection sleeve. As a result, a “laughing” phenomenon occurs in which the strands of the wire adjacent to the connection sleeve are loosened and scattered.
Wires with loose wires cause various problems such as increased resistance, abnormal heating, and corrosion of wires due to the ingress of rainwater. There is a need to.
Conventionally, a bind wire, a rubber tube or the like is tightly wound around the electric wire portion near the connection sleeve by human power so that the strands are not scattered. However, there is a case where the tightening force is insufficient in the work by human power, and it is not possible to completely prevent the strands from being scattered.
Here, Patent Literature 1 describes an electric wire sleeve compression aid for horizontally holding an electric wire at a compression connection location. The auxiliary tool includes a grip clip for gripping the electric wire so as not to move. Since the electric wire held by the holding clip is prevented from moving in the longitudinal direction at the time of compression connection and rotating around the central axis of the electric wire, it is possible to effectively prevent the wires from being scattered.

In contrast, the belt-like member is supported so as to be wound in opposite directions.

本発明によれば、電線に巻き付けた帯状部材の張力を増大させることにより、電線を強固に締め付けるので、電線のばらけを防止することができる。また、ばらけ防止具は帯状部材を電線に巻き付ける構成であるので、電線の直径に関わらずばらけ防止具を使用でき、汎用性が高い。   According to the present invention, since the electric wire is firmly tightened by increasing the tension of the belt-shaped member wound around the electric wire, the electric wire can be prevented from being scattered. Moreover, since the anti-scattering device is configured to wind the belt-shaped member around the electric wire, the anti-scattering device can be used regardless of the diameter of the electric wire, and is highly versatile.

A band-shaped member and a winding tool constituted by the band-shaped member will be described with reference to FIG. Fig.2 (a) is a perspective view of a winding tool, (b) is an expanded view of a winding tool, (c) is a figure which shows the edge part structure of a winding tool.
The strip member 11 is a long strip member. One wrapping tool 10 is configured including at least one strip-shaped member 11 and two cylindrical portions 13 disposed at both longitudinal ends of the strip-shaped member 11.
The strip-shaped member 11 has a length that can be wound around the electric wire W at least once. The belt-like member 11 has a strength capable of withstanding the tension (tension) when tension is applied to the wire W so as to prevent the electric wire from being scattered (when it is tensed).
For example, a leather belt having a width of about 20 mm to 30 mm and a thickness of about 3 to 5 mm can be used for the belt-like member 11. In addition, as long as the strip | belt-shaped member 11 has the softness | flexibility and intensity | strength which can clamp | tighten the electric wire W firmly, the thing of what kind of material may be used.

The tubular portion 13 may be formed by sewing a part of the belt-like member 11 into a tubular shape. Alternatively, a member separate from the belt-like member 11 may be formed in a cylindrical shape and integrated with the belt-like member 11. 2B shows an example in which a belt-like member different from the belt-like member 11 is spirally joined and formed into a cylindrical shape, and is integrated with the belt-like member 11 to form a cylindrical portion 13. ing.
The axial direction of the cylindrical portion 13 is inclined by a predetermined angle with respect to the longitudinal direction of the band-shaped member 11. The tubular portion 13 is integrated with the belt-like member 11 so as to extend along the longitudinal direction of the wire W when the belt-like member 11 is wound around the wire W in a spiral shape.
The winding tool 10 in the present embodiment includes two (two) band-like members 11. That is, the longitudinal end portions 11a and 11a of the strip-shaped members 11 have cylindrical portions 13a and 13a, respectively. The other end portions 11b and 11b in the longitudinal direction of each band-like member 11 are integrated into a V shape via one cylindrical portion 13b to form one winding tool 10.

Further, the first support member 23 and the second support member 27 have materials and configurations that are not easily deformed when a tension for tightening the electric wire W is applied to the band-shaped member 11. For example, the first support member 23 and the second support member 27 are made of, for example, a steel material or the like that is galvanized in the form of a long strip having a width of about 20 mm and a thickness of about 3 mm.

図3は、第一取付部の部分拡大斜視図であり、(a)は図1と同一の方向(正面方向)から観察した状態を示し、(b)は図1とは反対の方向(背面方向)から観察した状態を示す図である。

Can do. In this case, the winding member 101 can be attached to and detached from the second attachment portion 97 from above.
Since the gear portion 105 of the winding member 101 has a larger diameter than the small diameter portion 107, the gear portion 105 has a function of preventing the positional deviation of the winding member 101 in the axial direction.
The second attachment portion 97 has the same positional relationship with respect to the first attachment portion 25 as in the first and second embodiments. Thereby, the 1st attaching part 25 and the 2nd attaching part 95 can be supported so that the two strip | belt-shaped members 11 and 11 which comprise a pair may wind with respect to the electric wire W in a mutually reverse direction.
The second attachment portion 97 may include a stopper that closes the opening at the top of the recess 97a and prevents the winding member 101 from falling off from the recess 97a.

駆動部材111は、巻取部材101を直接的に回転させる中間回転部材113と、中間回転部材113を回転させる駆動回転部材119とを有する。

The intermediate rotation member 113 includes two drive gears 115 that are disposed at both ends in the axial direction and mesh with the gear portion 105 of the winding member 101, a worm wheel 117 that is disposed at the intermediate portion in the axial direction, and each drive gear 115. An intermediate rotating shaft portion 116 that is coaxially connected to the worm wheel 117 so as not to be relatively rotatable is provided. The intermediate rotation member 113 is supported by the second support member 93 so as to be able to rotate forward and backward so that the axial direction of the intermediate rotation shaft portion 116 extends along the longitudinal direction of the second support member 93.

駆動回転部材119は、ウォームホイール117と噛合するウォーム121(ねじ歯車)と、ウォーム121を正逆自在に回転させる操作ハンドル123を備える。駆動回転部材119は、その軸方向(ウォームホイール117の軸方向)が、接続フレーム95の長手方向に沿って伸びるように、第二支持部材93によって正逆回転自在に支持されている。

The drive rotating member 119 is supported by the second support member 93 so as to be rotatable forward and backward so that its axial direction (axial direction of the worm wheel 117) extends along the longitudinal direction of the connection frame 95.
Here, the worm wheel 117 is driven by the rotation of the worm 121, but is designed so that the worm 121 cannot be reversely driven even if the worm wheel 117 is rotated.
The operation handle 123 is exposed outside the second support member 93.

ばらけ防止具3の使用方法について、上記実施形態と異なる部分について説明する。
長手方向一端部11aを第一支持部材23によって支持された帯状部材11の長手方向他端部11bを、第二支持部材93に支持させる。即ち、巻取部材101の小径部107の下側約半周を凹所97aに嵌合させる。このとき巻取部材101のギヤ部105を中間回転部材113の駆動ギヤ115に噛合させる。
操作ハンドル123を操作してウォーム121を何れかの方向(図示の例では図中矢印B方向)に回転させると、ウォーム121の回転に応じて中間回転部材113が、ウォームホイール117を介して回転する(図示の例では図中矢印C方向に回転する)。また、中間回転部材113の回転に応じて巻取部材101が、駆動ギヤ115及びギヤ部105を介して回転して(図示の例では図中矢印D方向に回転して)、帯状部材11の長手方向他端部11bを順次巻き取っていく。
About the usage method of the anti-scattering tool 3, a different part from the said embodiment is demonstrated.
The second support member 93 supports the other end portion 11 b in the longitudinal direction of the belt-like member 11 in which the one end portion 11 a in the longitudinal direction is supported by the first support member 23. That is, the lower half of the small diameter portion 107 of the winding member 101 is fitted into the recess 97a. At this time, the gear portion 105 of the winding member 101 is engaged with the drive gear 115 of the intermediate rotating member 113.
When the operation handle 123 is operated to rotate the worm 121 in any direction (in the illustrated example, in the direction of arrow B in the figure), the intermediate rotating member 113 rotates via the worm wheel 117 according to the rotation of the worm 121. (In the example shown in the figure, it rotates in the direction of arrow C in the figure). Further, the winding member 101 rotates via the drive gear 115 and the gear portion 105 according to the rotation of the intermediate rotation member 113 (in the illustrated example, it rotates in the direction of arrow D in the figure), and the belt-shaped member 11 The other end 11b in the longitudinal direction is taken up sequentially.

巻取部材101が帯状部材11を巻き取るにつれて帯状部材11の張力が増大していき、帯状部材11は電線Wを強固に締め付ける。このとき、帯状部材11の張力によってウォームホイール117には巻取部材101を介して帯状部材11を巻き出す方向に回転させる力が加わる。しかし、ウォームホイール117からウォーム121を逆駆動できない構成となっているので、操作ハンドル123から手を離しても、帯状部材11が巻取部材101から巻き出されることはない。
そして、帯状部材11が所望の張力で電線Wを締め付けることができた場合には、電線Wの切断や圧縮接続等の作業を行えばよい。
なお、巻取部材101に操作ハンドル等を設け、巻取部材101を直接回転させる構成としてもよい。
As the winding member 101 winds up the strip member 11, the tension of the strip member 11 increases, and the strip member 11 tightens the electric wire W firmly. At this time, a force for rotating the belt-like member 11 in the direction of unwinding the belt-like member 11 via the winding member 101 is applied to the worm wheel 117 by the tension of the belt-like member 11. However, since the worm 121 cannot be reversely driven from the worm wheel 117, the strip-shaped member 11 is not unwound from the winding member 101 even if the operation handle 123 is released.
And when the strip | belt-shaped member 11 can clamp the electric wire W with the desired tension | tensile_strength, what is necessary is just to perform work, such as a cutting | disconnection of the electric wire W, and a compression connection.
In addition, it is good also as a structure which provides an operation handle etc. in the winding member 101 and rotates the winding member 101 directly.

以上のように本実施形態によれば、帯状部材11を電線Wに巻き付けると共に、張力調整機構としての巻取機構100により帯状部材11の張力を増大させて、電線Wを帯状部材11によって強固に締め付ける。即ち、巻取機構100により帯状部材11の長手方向他端部11bを巻き取って電線Wを帯状部材11によって強固に締め付けるので、電線Wを圧縮接続する場合や切断する場合にも、素線のばらけを防止できる。
また、帯状部材11を電線Wに巻き付ける構成であるので、電線の直径に関わらず、ばらけ防止具3を使用できる。
また、電線Wを締め付ける際に帯状部材11を巻き取るため、第一支持部材23と第二支持部材93との間隔を短縮することができ、ばらけ防止具1を小型化できる。
また、電線Wを締め付ける際には、操作ハンドル123を介してウォーム121を回転させるので、非常に軽い力による操作を可能としながらも、電線Wを強固に締め付けることができる。
また、ばらけ防止具3のフレーム部材91部分をネジ止め固定等により分解可能に構成することができ、この場合は非使用時にコンパクト化することができ、収納スペースを取らない。
As described above, according to the present embodiment, the belt-like member 11 is wound around the electric wire W, and the tension of the belt-like member 11 is increased by the winding mechanism 100 as a tension adjusting mechanism. tighten. That is, the other end portion 11b in the longitudinal direction of the belt-like member 11 is wound by the winding mechanism 100 and the electric wire W is firmly tightened by the belt-like member 11. Therefore, even when the electric wire W is compression-connected or cut, Can prevent looseness.
Moreover, since it is the structure which winds the strip | belt-shaped member 11 around the electric wire W, the anti-scattering tool 3 can be used irrespective of the diameter of an electric wire.
Moreover, since the strip | belt-shaped member 11 is wound up when tightening the electric wire W, the space | interval of the 1st support member 23 and the 2nd support member 93 can be shortened, and the anti-scattering tool 1 can be reduced in size.
Further, since the worm 121 is rotated via the operation handle 123 when the electric wire W is tightened, the electric wire W can be firmly tightened while enabling an operation with a very light force.
Further, the frame member 91 portion of the anti-scattering device 3 can be configured to be disassembled by fixing with screws or the like. In this case, it can be made compact when not in use, and does not take up storage space.
