SELF-PROPELLED TYPE PIPE INSIDE INSPECTION CAMERA DEVICE AND PIPE DIAMETER CONVERSION UNIT

摘要

PROBLEM TO BE SOLVED: To provide a self-propelled type pipe inside inspection camera device which takes, as the object, pipes having a wide range of pipe diameters (350 mm to 800 mm) among which the largest is twice or more the smallest, and smoothly travels in a pipe to be inspected at an appropriate speed to uniformly and exactly observe the inside of the pipe.;SOLUTION: The self-propelled type pipe inside inspection camera device which copes a plurality of kinds of pipe diameters comprises: a pipe diameter conversion unit 1 constituting a traveling unit; an attachment adapter 13 for the pipe diameter conversion adapter, which is selectively coupled to the pipe diameter conversion unit 1; and first to third pipe diameter conversion adapters (CA1) to (CA3).;COPYRIGHT: (C)2013,JPO&INPIT
