管路内走行装置
Document Type and Number:
Japanese Patent JP7298868
Kind Code:
B2
Abstract:
To provide an in-pipeline travel device which can correspond to a pipe diameter difference of piping, can achieve simplification and down-sizing of a device, and has high travel performance.SOLUTION: An in-pipeline travel device 10 comprises a body part 14 which is held in a pipeline 90 which becomes a travel object by a rotary brush 20A and a support part 20B constituting a drive wheel, and a motor 12. A rotation axis of the rotary brush 20A is located at a position separated from a central axis of the pipeline so as to be substantially orthogonal to the central axis in an installation state into the pipeline 90. A hair part 24 of the rotary brush 20A is so configured that only the hair part 24 on a side near a pipeline inner wall 92 has a length contacting the inner wall 92 in an elastically deformed state, and is rotated in an installation state into the pipeline 90, and thus, has elasticity capable of giving propulsive power to the pipeline. In an installation state into the pipeline 90, the support part 20B is provided at a position where the support part contacts the inner wall 92 and can hold the body part 14 in the pipeline 90 together with the rotary brush 20A.SELECTED DRAWING: Figure 1
