To provide a pulley winding prevention apparatus that allows smooth passing of a wire rope and prevents winding of a foreign object into a sheave, and a pulley.SOLUTION: A winding prevention apparatus 102 is mounted to a pulley 100 onto which a wire rope 108 is wound. The winding prevention apparatus 102 comprises: a pair of arms 112a, 112b rotatably attached to both sides of a sheave 106; a pair of side walls 110a, 110b provided to tips of the arms 112a, 112b; and a plurality of beam members (first beam member 114a to third beam member 114c) passing to the side walls 110a, 110b to enclose the wire rope 108. Among the plurality of beam members, a part of the beam members (second beam member 114b, third beam member 114c) is openable/closable from the side walls 110a, 110b, and each beam member has a concave curved surface toward the wire rope 108.SELECTED DRAWING: Figure 1

    【課題】ワイヤロープを円滑に通過させつつ索輪への異物の巻込みを防ぐ滑車用巻込防止装置および滑車を提供する。【解決手段】巻込防止装置102は、ワイヤロープ108のかかる滑車100に取り付けられる。巻込防止装置102は、索輪106の両面側に回転可能に取り付けられる一対のアーム112a、112bと、アーム112a、112bの先端にそれぞれ設けられた一対の側壁110a、110bと、側壁110a、110b同士に渡されてワイヤロープ108を囲う複数の梁部材(第1梁部材114a〜第3梁部材114c)とを備える。複数の梁部材のうち、一部の梁部材(第2梁部材114b、第3梁部材114c)は側壁110a、110bから開閉可能になっていて、各梁部材はワイヤロープ108に向かって凸の曲面を有している。【選択図】図1
