Description
本発明は、電力の送電線及び配電線を緊張する際に使用される、ケーブル（電線）を掴む掴線器に関するものであり、ウィンチのフック等を接続する長レバーのリング部に工夫を加えることによって、ケーブル表面に生じる屈曲クセ及び損傷を防止するためのものである。 The present invention relates to a wire gripper for gripping a cable (electric wire) used when tensioning a power transmission line and a distribution line, and adds a device to a ring portion of a long lever connecting a winch hook or the like. This is to prevent the bending habit and damage generated on the cable surface.
従来からテコを利用した掴線器は、長レバーとその端部にあるリング部が同一平面上にある掴線器が使用されている。（図２参照） Conventionally, a gripper using a lever has a gripper in which a long lever and a ring portion at an end thereof are on the same plane. (See Figure 2)
しかしながら長レバーとリング部が同一平面上にある掴線器では、リング部の上部がケーブルに干渉してリング部中心をケーブル中心に接近させることが出来ない欠点があった。（図２ｂ参照） その為、ケーブル中心とリング部中心との位置が大きくズレることになる。このズレの大きさが、ケーブルを緊線した際にケーブルを屈曲させることになる。
（図３参照）
この屈曲によるケーブル表面に生じる屈曲のクセ及び損傷等（図４参照）の不都合を解決することを課題とする。
However, in the gripping device in which the long lever and the ring portion are on the same plane, the upper portion of the ring portion interferes with the cable and the center of the ring portion cannot be brought close to the center of the cable. (See FIG. 2b) Therefore, the position of the center of the cable and the center of the ring portion are greatly displaced. The size of this deviation causes the cable to be bent when the cable is tightened.
(See Figure 3)
It is an object of the present invention to solve inconveniences such as bending habit and damage (see FIG. 4) generated on the cable surface due to this bending.
本発明は、掴線器の長レバーのリング部を１５°〜４５°の角度に捻ることにより、リング部の上部がケーブルに干渉することを避けてリング部中心をケーブル中心に接近させることが出来ることにより（図１参照）及び（図１ｂ参照）、上記課題を解決するものである。この角度の範囲外では実用的に不適当である。 In the present invention, by twisting the ring portion of the long lever of the gripper to an angle of 15 ° to 45 °, the center of the ring portion can be brought closer to the center of the cable while preventing the upper portion of the ring portion from interfering with the cable. By doing so (see FIG. 1) and (see FIG. 1b), the above-mentioned problems are solved. Outside the range of this angle, it is not practically appropriate.
本発明による掴線器は、部品数を増やす必要もなく、只、長レバーのリング部を捻るだけで容易に製作できる。また、ケーブル表面の損傷等（図４参照）を防止して、長期間設置され続けるケーブルの信頼性を向上させることが出来る利点がある。 The gripping device according to the present invention can be easily manufactured by simply twisting the ring portion of the hook and the long lever without increasing the number of parts. Further, there is an advantage that the cable surface can be prevented from being damaged (see FIG. 4) and the reliability of the cable that has been installed for a long time can be improved.
図１に示すように、掴線器の長レバー１の端部にあるリング部２を１５°〜４５°の角度に捻ることは容易に出来、部品数も増えずコストも最小にできる。更に、同一平面上にある、従来使用されている長レバーに比較しても、有効にリング部中心をケーブルに干渉させずに、ケーブル中心に接近させることが出来る。 As shown in FIG. 1, the ring portion 2 at the end of the long lever 1 of the gripper can be easily twisted to an angle of 15 ° to 45 °, and the number of parts is not increased and the cost can be minimized. Furthermore, even when compared with a conventionally used long lever on the same plane, the center of the ring portion can be brought closer to the center of the cable without causing interference with the cable.
