BUCKET LINK DEVICE WITH HOOK AND CONSTRUCTION MACHINE INCLUDING THE SAME
To make it possible to, in a bucket link device with hook, effectively prevent wear of or damage to a hook body and a locking member by minimizing free play of the hook body.SOLUTION: A holding part 30 that holds a hook body 23 in a storage position is provided in a storage part 12b in which a hook device 20 is stored. The holding part 30 is provided with: a first guide member 31 and a second guide member 32 between which the hook body 23 is sandwiched to be stored in the storage position; and a locking member 35 supported with respect to the first guide member 31, swingably between a locking position where the hook body 23 is held in the storage position and a release position where the hook body 23 can be released from the locking position. A contact part 35b in the locking member 35, which prevents the hook body 23 from detaching in the locking position, is designed to have a curve surface shape in accordance with a curved surface shape of a tip side 23a of a hook part so as to be able to come into line contact with a length direction of the hook part of the hook body 23 or to come into surface contact with the hook part.SELECTED DRAWING: Figure 4A
【課題】フック付バケットリンク装置において、フック本体のガタツキを最小限にしてフック本体及びロック部材の摩耗や損傷を効果的に防止できるようにする。【解決手段】フック装置２０が収納される収納部１２ｂにフック本体２３を収納位置に保持する保持部３０を設ける。保持部３０に、フック本体２３を収納位置に収納されるように挟み込む第１ガイド部材３１及び第２ガイド部材３２を設け、第１ガイド部材３１に対し、フック本体２３を収納位置に保持するロック位置及びこのロック位置から解除可能とする開放位置の間で揺動可能に支持されたロック部材３５とを設ける。ロック部材３５における、ロック位置でフック本体２３の抜けを防止する当接部３５ｂをフック本体２３の鉤部の長さ方向に対して線接触又は鉤部に対して面接触可能なように、鉤部の先端側２３ａの曲面形状に合わせて曲面形状とする。【選択図】図４Ａ
