PROBLEM TO BE SOLVED: To provide an electric wire tensioning device which can easily and quickly tense wiring with a predetermined tensile force.SOLUTION: An electric wire tensioning device 1 comprises: a winder 2 that connects wiring in a predetermined tensile force by winding a chain 6 connected to the wiring; and a tension gauge 3 that measures the tensile force of wiring. The tension gauge 3 is intervened between the winder 2 and a coupler 11 engaged to a pole, and instructs the tensile force on the basis of constriction of a disc spring 29 constricting by relative displacement of the winder 2 and the coupler 11 by winding the chain 6. It rotates on a display board 30d in which a measurement indicator 37 has a scale through a large gear 34 and a small gear 36 so as to interlock to the constriction of the disc spring 29 around a main shaft 35, and is further contacted to a limit switch 40 on a freely rotatable setting indicator 39 around the main shaft 35 on the display board 30d, thereby cutting off electric conduction to a motor 8. The setting indicator 39 is connected to a setting tab 38 fixed to the main shaft 35 by fastening a fixing nut 41 that is threadedly engaged with the main shaft 35 at a setting position.SELECTED DRAWING: Figure 2
【課題】 架線を所定の張力で簡単に素早く張ることができる電動張線装置を提供する。【解決手段】 電動張線装置1は、架線に連結するチェーン6を巻き取ることにより架線を所定の張力で接続する巻取り機2と、架線の張力を測定する張力計3とを具備させる。張力計3は、巻取り機2と支柱に係止した接続具11との間に介在させ、チェーン6の巻き取りによる巻取り機2と接続具11との相対移動により収縮する皿ばね29の収縮に基づいて張力を指示する。皿ばね29の収縮に連動して大歯車34及び小歯車36を介して測定指針37が目盛りを有する表示板30d上を主軸35周りに回転し、同じく表示板30d上を主軸35周りに回転自在の設定指針39上のリミットスイッチ40に当接してモータ8への通電を断つ。設定指針39は、設定位置で主軸35に螺合する固定ナット41を締め付けて主軸35に固定される設定つまみ38に結合する。【選択図】 図2
