PROBLEM TO BE SOLVED: To provide a piping inside moving and surveying device that, without involving complication of the structure of the device, moves and surveys in a plurality of pieces of piping having different diameters, piping having a T-shaped branched part to which a plurality of pieces of piping having different diameters are connected, piping having a bend part of which the diameter is continuously changed or piping in which the above mentioned piping are combined.SOLUTION: The piping inside moving and surveying device comprises: at least two crawlers coming in close contact with piping; linkage mechanisms which retain the crawlers respectively and can be extended and contracted in the axial direction; a joint which connects the respective linkage mechanisms; a camera mounted to the joint; and a crawler distance adjusting mechanism which is disposed in the linkage mechanisms and changes a distance between the crawlers. The piping inside moving and surveying device moves in the piping while extending or contracting the linkage mechanism in accordance with a diameter or a shape of the piping and/or while changing the distance between the crawlers by means of the crawler distance adjusting mechanism, and surveys inside of the piping with the camera.SELECTED DRAWING: Figure 2 |
