CLAMP DEVICE AND PILE PRESS-FITTING DEVICE
To effectively deal with cases where there is a bias in the direction of the moment generated due to the operating posture of an upper device and the work content in a clamp device that grips the open end of a tubular body.SOLUTION: A clamp device 10 for gripping an open end of a tubular body P comprises three or more clamp mechanisms 11, 12, 13, and 14 for sandwiching and clamping a side wall SW of the open end from the inside and the outside at different positions along the circumference of the open end, respectively. The three or more clamp mechanisms are arranged so that the clamping force on the side wall arranged on one side F of a virtual straight line, in which an open side of the open end is bisected by the virtual straight line AC in any direction passing through the center A, can be made larger than the clamping force on the side wall arranged on the other side of the virtual straight line.SELECTED DRAWING: Figure 2
【課題】筒体の開口端部を把持するクランプ装置において、上物装置の動作姿勢、作業内容により発生するモーメントの方向に偏りがある場合に効果的に対応する。【解決手段】筒体Ｐの開口端部を把持するクランプ装置１０であって、開口端部の周に沿って異なる位置でそれぞれ、開口端部の側壁ＳＷを内側と外側から挟んで挟持する挟持機構１１，１２，１３，１４を３以上備える。３以上の挟持機構は、開口端部の開口面をその中心Ａを通る任意の方向の仮想直線ＡＣで２等分したとき、当該仮想直線の一方側Ｆに配置される側壁に対する挟持力を、当該仮想直線の他方側に配置される側壁に対する挟持力より大きくすることができるように配置されている。【選択図】図２
