To develop a technique of surely realizing the prevention of reverse running of a wire when the tail tension of the wire between a winch and a take-up device is lost.SOLUTION: A wire reverse running prevention device 10 includes a reverse running detection head 30 which holds a wire W by a plurality of rolls 33, 34 and is located on the downstream side in the movement direction when winding the wire W with respect to a wire fixing tool 22. The reverse running detection head 30 permits the rotation of the roll 33 following the movement in the moving direction in winding the wire by a one-way clutch 32 and regulates the reverse rotation, moves by following the wire W, which reversely runs, to press and rotate an arm 20 attached with a fixing tool, and changes the orientation of the wire fixing tool 22 on a tip end of the arm 20 attached with the fixing tool so as to fix the wire W to the wire fixing tool 22.SELECTED DRAWING: Figure 1
【課題】ウインチと巻き取り装置との間のワイヤの尻手張力が失われたときにワイヤの逆走防止を確実に実現できる技術の開発。【解決手段】ワイヤWを複数のロール33、34によって保持してワイヤ固定器具22に対してワイヤWの巻き取り時移動方向下流側に配置される逆走検知ヘッド30を有し、逆走検知ヘッド30は一方向クラッチ32によってワイヤの巻き取り時移動方向への移動に対するロール33の従動回転を許可しかつ逆向き回転を規制して、逆走したワイヤWに追従移動することで固定器具付きアーム20を押圧して回転させ、固定器具付きアーム20先端のワイヤ固定器具22の向きを変更させてワイヤ固定器具22にワイヤWを固定させるワイヤ逆走防止装置10を提供する。【選択図】図1
