CYLINDRICAL STRUCTURE DEMOLITION APPARATUS AND CYLINDRICAL STRUCTURE DEMOLITION METHOD
To provide a cylindrical structure demolition apparatus capable of demolishing a cylinder from its upper part and suspending and lowering a demolished object to the ground without arranging any workers.SOLUTION: A cylindrical structure demolition apparatus includes: a fixation part 3 that is fixed on a cylinder 10 by pressing an inner surface of the cylinder 10; a plurality of circular saws 41 of cutting the inner surface of the cylinder 10 at different positions in the circumferential direction of the cylinder 10; a plurality of circular saw support mechanisms 42 for supporting the plurality of circular saws 41; and a frame 40 that has the plurality of circular saw support mechanisms 42 provided thereon and is assembled to the fixation part 3 in a revolvable manner. The frame 40 is driven so as to revolve around a revolving axis RX along a center line of the cylinder 10 in a state in which the fixation part 3 is fixed on inner surface of the cylinder 10. Each circular saw support mechanism 42 include: a circular saw moving mechanism 421 for moving a circular saw 41 in a direction accessing the inner surface of the cylinder 10 and in a direction separating from the inner surface of the cylinder 10; and a circular saw rotating mechanism 422 for performing switching of a cutting direction of the circular saw 41 between the circumferential direction and longer direction.SELECTED DRAWING: Figure 9
【課題】作業者を配置せずに筒身を上部から解体し、解体物を地面へ吊り降ろすことができる筒状構造物解体装置を提供する。【解決手段】筒身１０の内面を押圧することにより筒身１０に固定される固定部３と、筒身１０の周方向の異なる位置で筒身１０の内面を切断する複数の丸鋸４１と、複数の丸鋸４１を支持する複数の丸鋸支持機構４２と、複数の丸鋸支持機構４２が設置され、固定部３に対して旋回可能に組み合わされたフレーム４０とを有する。フレーム４０は、固定部３が筒身１０の内面に固定された状態において、筒身１０の中心線に沿った旋回軸ＲＸの周りで旋回するように駆動される。丸鋸支持機構４２は、筒身１０の内面に近づく方向及び筒身１０の内面から離れる方向に丸鋸４１を移動させる丸鋸移動機構４２１と、丸鋸４１の切断方向を周方向と長手方向とに切り替える丸鋸回転機構４２２とを含む。【選択図】図９
