PROBLEM TO BE SOLVED: To provide a piping inspection device which can be proof against meandering in an inside of the piping and easily inserted into the inside through a branch pipe fitted to the piping.SOLUTION: Inspection means 12 to inspect an inside of a piping 1 are installed on a guide frame 14 and the guide frame 14 comprises a plurality of frame members 22-24 and a plurality of connection members 27 which connect each frame member 22-24 with the other. The connection members 27 connect each frame member 22-24 so as to make each frame member bent in one direction C but to make bending of the frame member 22-24 regulated in other direction. The frame members 22-24 have bending range limiting parts and when the bending range limiting parts of the frame members 22-24 touch neighboring frame members 22-24, then the bending range of the guide frame 14 in the direction C is restricted.SELECTED DRAWING: Figure 3
【課題】配管内で蛇行するのを防止することができ、配管に設けられた分岐管から配管内に容易に挿入することが可能な配管用調査装置を提供する。【解決手段】配管1内を調査する調査手段12がガイドフレーム1414に設けられ、ガイドフレーム14は、複数のフレーム部材22〜24と、各フレーム部材22〜24同士を連結する複数の連結部材27とを有し、連結部材27は、各フレーム部材22〜24同士を一方向Cに屈曲可能に連結するとともに、フレーム部材22〜24同士の他方向への屈曲を規制し、フレーム部材22〜24は屈曲範囲制限部を有し、フレーム部材22〜24の屈曲範囲制限部が隣接するフレーム部材22〜24に当接すると、ガイドフレーム14の一方向Cへの屈曲範囲が制限される。【選択図】図3
