BURIED OBJECT GRIPPING DEVICE AND PILE CUTTING DEVICE EQUIPPED THEREWITH
To make it difficult for the gripped state to be released even if a force is applied from an underground buried object when the buried object is gripped.SOLUTION: A buried object gripping device 2 includes a cylindrical body 3 buried in the ground 9 so that a buried object in the ground 9 passes through it along its central axis, and a shell structure 4 provided on the cylindrical body 3 and switchable between a non-contact position away from the buried object and a contact position in which the shell structure comes into contact with the buried object. The shell structure 4 includes a shell portion 41 formed in an arc shape in a top view when the shell structure 4 is switched to the non-contact position, a shaft portion 43 that supports the shell portion 41 rotatably relative to the cylindrical body 3 with a rotation axis extending parallel to a chord 42 of the shell portion 41 when viewed from above, and a blade portion 44 provided at an upper end of the shell portion 41 when the shell structure 4 is switched to the non-contact position and that comes into contact with the buried object when the shell structure 4 is switched to the contact position by rotating around the rotation axis of the shaft portion 43.SELECTED DRAWING: Figure 2
【課題】地中の埋設物を把持した際に、埋設物から力が加わっても、把持状態が解除されにくくすること。【解決手段】埋設物把持装置２は、地中９の埋設物を中心軸に沿って通すように地中９に埋め込まれる筒体３と、筒体３に設けられ、埋設物から離れた非接触位置と埋設物に当たる接触位置とに切替え可能なシェル構造体４と、を備える。シェル構造体４は、シェル構造体４が非接触位置に切り替えられた状態において、上面視で円弧状に形成されたシェル部４１と、上面視におけるシェル部４１の弦４２に平行に延びた回転軸で、シェル部４１を筒体３に対して回転可能に支持する軸部４３と、シェル構造体４が非接触位置に切り替えられた状態においてシェル部４１の上端部に設けられ、軸部４３の回転軸を中心に回転することでシェル構造体４が接触位置に切り替えられると、埋設物に当たる刃部４４と、を有する。【選択図】図２
