FOUR-LEG BLOCK REVERSING DEVICE
To provide a four-leg block reversing device in which the workability is good because placing in a normal stance is stable and the normal stance can be changed to an upside-down stance and bow tie stance, and that does not need a large drive mechanism and can simplify a device configuration.SOLUTION: The four-leg block reversing device is characterized by including a stopper arm 83 that can be changed selectively between: an upside-down stance holding position in which, at the lower position of right and left rails 81 that support two legs a and b of three legs a, b and c which form the triangle bottom of a four-leg block B hung by a crane, the leg c is held in an upside-down stance at the position for which the leg c is rotated downward between the two rails 81 and becomes the upside-down stance; and a retract position for which the leg c is rotated downward between the two rails 81 and reaches a bow tie position.SELECTED DRAWING: Figure 4
【課題】 正姿勢の置き方を一定とし、同じ正姿勢の位置から倒立姿勢でも、蝶々姿勢でも変更できる作業性の良好で、しかも大きな駆動機構が不要で、装置構成が簡素化できる４脚ブロックの反転装置を提供する。【解決手段】 クレーンで吊持した４脚ブロックＢの三角形の底面を構成する３つの脚ａ、ｂ、ｃのうちの２つの脚ａ、ｂを支持する左右２本のレール８１の下方位置に、残りの１つの脚ｃが前記２本のレール間８１で下向きに回転して倒立姿勢まで回転した位置で残りの１つの脚ｃを倒立姿勢に保持する倒立姿勢保持位置と、残りの１つの脚ｃが前記２本のレール８１間で下向きに蝶々位置まで回転する退避位置とに選択的に位置変更可能なストッパーアーム８３を設けたことを特徴とする。【選択図】 図４
