PROBLEM TO BE SOLVED: To provide an in-pipe travel device capable of quickly guiding a travel direction to a curve direction of a pipe by changing a roll attitude angle on the spot in the pipe.SOLUTION: An in-pipe travel device 1 comprises four link parts 2 arranged in a zigzag shape and a plurality of moving units provide between the link parts 2 and at opening side end parts. Two moving units 3a, 3b overhanging to one side of a pipe 10 in a radial direction are first omnidirectional moving members 32 that can move actively in an axial direction of the pipe 10 and passively in a circumferential direction. Wheel units 4a, 4b overhanging to the other side of the pipe 10 in the radial direction are roll rotating members that can move actively in the circumferential direction of the pipe 10 and passively in the axial direction of the pipe to change roll attitude angles. A moving member of a moving unit 5 is a second omnidirectional moving member 52 that can move in the axial direction and the circumferential direction of the pipe 10. The in-pipe travel device also comprises energizing means for pressing the first omnidirectional moving members 32 against an inner wall surface 11a of the pipe 10.SELECTED DRAWING: Figure 2
【課題】配管内においてその場でロール姿勢角を変えることにより進行方向を迅速に配管の湾曲方向に合わすことができる管内走行装置を提供する。【解決手段】ジグザグ状に配列される4つのリンク部2とリンク部2間及び開放側端部に設けられる複数の移動ユニットとを備え、配管10の径方向の一方側に張り出す2つの移動ユニット3a、3bは、配管10の軸方向へ能動的且つ周方向へ受動的に移動可能な第1全方向移動部材32であり、配管10の径方向の他方側に張り出す車輪ユニット4a、4bは、ロール姿勢角を変えるために、配管10の周方向へ能動的且つ配管の軸方向に受動的に移動可能なロール回転用部材であり、移動ユニット5の移動部材は、配管10の軸方向へ移動可能、且つ、周方向へ移動可能な第2全方向移動部材52であり、第1全方向移動部材32を配管10の内壁面11aに押し付けるための付勢手段を備える管内走行装置1。【選択図】図2
