PROBLEM TO BE SOLVED: To provide an entanglement prevention device for a metal pulley which can be easily attached to/detached from the metal pulley.SOLUTION: An entanglement prevention device 10 comprises a rubber plate member 1, a pair of band plate-like connection members 2 and 2 and a pair of protection tubes 3 and 3. The rubber plate member 1 has a cross-shape cut line 1c through which a hook 93f can be freely inserted at a center part thereof, and has a pair of fasteners 4a and 4a at both end parts thereof. The connection members 2, in which second fasteners 4b that can be attached to/detached from the first fasteners 4a are continuously provided in a longitudinal direction, can cover a frame 92 from above the fasteners. In the protection tubes 3, a pair of flange parts 3f and 3f are provided at part of an outer periphery thereof. When the pair of flange parts 3f and 3f are opened, a wire rope Wr can be introduced from a direction of the outer periphery of the tube. When the pair of flange parts 3f and 3f are closed, the wire rope Wr can be stored inside the tube. In the protection tubes 3, the first fasteners 4a are provided at one ends at the opposite sides of the flange parts 3f. The entanglement prevention device 10 can be easily attached to/detached from an existing metal pulley 90.SELECTED DRAWING: Figure 1
【課題】金車に着脱容易な金車用巻き込み防止装置を提供する。【解決手段】巻き込み防止装置10は、ゴム板部材1、一対の帯板状の連結部材2・2、及び、一対の防護管3・3を備える。ゴム板部材1は、フック93fが挿通自在な十字状の切れ目1cを中央部に有し、一対の第1留め具4a・4aを両端部に有する。連結部材2は、第1留め具4aと着脱自在な第2留め具4bを長手方向に連設し、フレーム92をその上方から覆うことができる。防護管3は、一対の鍔部3f・3fを外周の一部に設けている。一対の鍔部3f・3fを開くと、ワイヤーロープWrをその外周方向から導入できる。一対の鍔部3f・3fを閉じると、ワイヤーロープWrを内部に収容できる。防護管3は、鍔部3fと反対側の一方の端部に第1留め具4aを設けている。巻き込み防止装置10は、既設の金車90に容易に着脱できる。【選択図】図1
