Title:
IN-PIPE MOVING DEVICE
Document Type and Number:
Japanese Patent JP2011161564
Kind Code:
A
Abstract:

To provide an in-pipe moving device capable of smoothly moving, even if an internal shape of a pipe body is changed.

This in-pipe moving device includes a spiral body 2 made by spirally winding a flexible longitudinal member 5 by a plurality of turns and a propulsion mechanism 7 for generating propulsive force in an axial direction of the spiral body 2. The propulsion mechanism 7 includes a plurality of driving mechanisms 3 provided in each of a plurality of driving force generating parts 10 arranged dispersedly along an extension direction of the longitudinal member 5. Each of the plurality of driving mechanisms 3 generates the propulsive force by applying driving force in a direction inclined to an axially orthogonal direction of the spiral body 2 in the corresponding driving force generating part 10, and is capable of adjusting an action direction of the driving force.
