BUCKET LINK DEVICE INSTALLED WITH HOOK AND CONSTRUCTION MACHINE HAVING THE SAME
To provide a bucket link device installed with hook that is hardly broken and has a simple structure.SOLUTION: A hook device 20 is stored sideways along a bottom plate 12f of a bucket link body part 12a in a storage part 12b. The storage part is provided with a holding part 30 for holding a hook body 23 in a storage position. The holding part 30 is provided with a guide member 31 into which the hook body 23 is fitted so as to be stored in a storage position, a cam shaft 32 that is in a position further away from the bottom plate 12f of the bucket link body part 12a than the guide member 31 and that is rotatably supported between a lock position R for holding the hook body 23 in a storage position and an open position L capable of releasing from the lock position R, and an urging spring 34 for urging the cam shaft 32 so as to return to the lock position R. The cam shaft 32 is provided with a recessed part 32a so as to switch from an arc-shaped section to a recessed section in a part in contact with the hook body 23.SELECTED DRAWING: Figure 1
【課題】フック付バケットリンク装置を破損しにくく簡単な構造のものにする。【解決手段】フック装置２０がバケットリンク本体１２ａの底板１２ｆに沿って横向きに収納される収納部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が収納位置に収納されるように嵌まり込むガイド部材３１と、バケットリンク本体１２ａの底板１２ｆに対してガイド部材３１よりも離れた位置にあり、フック本体２３を収納位置に保持するロック位置Ｒ及び、このロック位置Ｒから解除可能とする開放位置Ｌの間で回動可能に支持されたカム軸３２と、カム軸３２をロック位置Ｒに戻るように付勢する付勢バネ３４とを設ける。カム軸３２を、フック本体２３が当接する部分において、円弧状断面と凹状断面とが切り換わるように凹状部３２ａを設ける。【選択図】図１
