To provide an in-pipe moving device that enables a moving body to move over long distances.SOLUTION: An in-pipe moving device comprises: a moving body that is provided in a pipe, has an expansion/contraction part that expands in a pipe diameter direction when fluid is supplied and contracts in the pipe diameter direction when the supplied fluid is discharged, comes into close contact with an inner peripheral surface of the pipe to block the inside of the pipe when the expansion/contraction part expands, and has a maximum outer diameter when the expansion/contraction part contracts smaller than an inner diameter of the pipe; fluid supply/discharge means that is provided outside the pipe, and controls the expansion/contraction of the expansion/contraction part by supplying or discharging fluid to the moving body through the pipe; a lid body that closes an opening part used when the moving body is arranged in the pipe; and pressing means that supplies fluid to the space between the lid body and the moving body and presses the moving body when the expansion/contraction part expands to block the inside of the pipe.SELECTED DRAWING: Figure 1

    【課題】移動体の長距離の移動を可能とする管内移動装置を提供することを目的とする。【解決手段】配管内に設けられ、流体の供給により管径方向に膨張し、供給された流体を排出することにより管径方向に収縮する膨縮部を有し、膨縮部が膨張したときに配管の内周面に密接して配管内を閉塞し、膨縮部が収縮したときの最大外径が配管の内径よりも小さく構成された移動体と、配管外に設けられ、管を通じて前記移動体に流体を供給又は排出することにより、前記膨縮部の膨張・収縮を制御する流体給排手段と、前記移動体を配管内に配置するときに利用した開口部を閉鎖する蓋体と、前記膨縮部が膨張して移動体が配管内を閉塞した状態にあるときに、前記蓋体と前記移動体の間の空間に流体を供給し、前記移動体を押圧する押圧手段とを備えた構成とした。【選択図】図1
