BUCKET LINK DEVICE WITH HOOK AND CONSTRUCTION MACHINE COMPRISING THE SAME
To securely prevent a removal stop part of a hook body from being damaged in a bucket link device with a hook.SOLUTION: In a housing part 12b in which a hook device 20 is housed, a removal stop part 24 is provided on the tapering tip side 23a of a hook and, at a housed position, a holding part 30 for holding a hook body 23 whose root side 23b has a width longer than that of its tip side is provided. At the holding part 30 are provided a first guide member 31 and a second guide member 32 for interposing the hook body 23 therebetween so that the hook body is housed at the housed position. The interval W between the first guide member 31 and a second guide member 32 is made to be wider than the width W1 of the tip side 23a of the hook and be narrower than the width W2 of the root side 23b of the hook so that the hook body 23 is prevented from being inserted from the root side 23b where the removal stop part 24 does not exist and the hook body is permitted to be inserted from the tip side 23a where the removal stop part 24 exists.SELECTED DRAWING: Figure 4B
【課題】フック付バケットリンク装置において、フック本体の抜け止め部の損傷を確実に防ぐ。【解決手段】フック装置２０が収納される収納部１２ｂに、鉤部の先細となった先端側２３ａに外れ止め部２４を設け、根元側２３ｂが先端側よりも幅が広いフック本体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を設ける。フック本体２３が外れ止め部２４のない根元側２３ｂから挿入されるのを防ぐ一方、外れ止め部２４のある先端側２３ａから挿入されるのを許容するように、第１ガイド部材３１及び第２ガイド部材３２の間隔Ｗを、鉤部の先端側２３ａの幅Ｗ１よりも広く鉤部の根元側２３ｂの幅Ｗ２よりも狭くする。【選択図】図４Ｂ
