AI Technical Summary
【0008】 本発明によると、回転部材により、所定の軸を中心に当接部材が回転されることで、当接部材が突起に当接される。当接部材が突起に当接した状態で、回転抑制部材により、当接部材が所定の軸を中心に回転するのが抑制される。これにより、ウインチドラムの回転を規制することができる。そして、ウインチドラムの軸方向に直交する方向における当接部材の中心は、所定の軸から偏心した位置に位置している。よって、当接部材を回転させることで、当接部材が突起に当接する位置を細かく調整することができる。これにより、ウインチドラムの回転を規制する位置を細かく調整することができる。また、当接部材を回転させることで、特定の力(トルク)で当接部材を突起に当接させることができる。これにより、ウインチドラムの回転を、ガタつくことなく規制することができる。また、突起と差込穴と治具とが、ウインチに配置されているので、特許文献1のように、ウインチとは別の構造体に配置された部材との間で位置調整を行う必要がない。よって、回転規制装置の装着や取り外し、持ち運びを容易に行うことができる。

Abstract
Claims
1. A winch drum with a flange, In the axial direction of the winch drum, a winch plate is positioned opposite the flange, A rotation restricting device for a winch drum provided on a winch having the following features: On the side surface or outer circumference of the flange, a plurality of protrusions are provided at predetermined intervals in the circumferential direction of the flange, The insertion hole formed in the winch plate, A jig that can be inserted into the insertion hole in the axial direction, It has, The aforementioned jig is A block that fits into the aforementioned insertion hole, A contact member is disposed on the flange side of the block and is capable of contacting the projection, A rotating member that can bring the contact member into contact with the projection by rotating the contact member around a predetermined axis parallel to the axial direction, A rotation suppressing member that prevents the contact member from rotating about a predetermined axis while the contact member is in contact with the projection, It has, A rotation restricting device for a winch drum, characterized in that the center of the contact member in a direction perpendicular to the axial direction is located at an eccentric position from the predetermined axis.
2. The aforementioned block has a through hole formed in the axial direction, The jig has a shaft that is inserted through the through hole, The contact member is provided at the flange-side end of the shaft, The rotating member is attached to the end of the shaft opposite to the flange, and by rotating the shaft around the predetermined axis, the contact member is rotated around the axis of the shaft. The rotation restricting device for a winch drum according to claim 1, characterized in that the rotation restricting member restricts the rotation of the contact member by restricting the rotation of the shaft.
3. The aforementioned block has a plurality of through holes formed therein. The rotation restricting device for a winch drum according to claim 2, characterized in that the shaft is inserted through one of the plurality of through holes.
4. The block is cylindrical with the axial direction as its axis, The rotating member rotates the block around the predetermined axis, which is the axis of the block, thereby rotating the contact member around the axis of the block. The rotation restricting device for a winch drum according to claim 1, characterized in that the rotation restricting member restricts the rotation of the block, thereby restricting the rotation of the contact member.
