    • PURPOSE:To allow a device to be freely moved inside a pipe with various changes by providing a clip force generating mechanism energizing a pair of arms in a direction narrowing the clip angle. CONSTITUTION:Both arms 1, 2 can not held opening against the energizing force (f) generated by a clip force generating mechanism 7 corresponding to the inner diameter of a pipe, thus wheels 4, 5 are pressed to one surface section 8b of a pipe inner wall face, on the other hand a drive wheel 6 is pressed to the other surface section 8a opposite in the diameter direction by the reaction force, thereby this device can be eventually erected and stabilized in the pipe 8. At this time, the direction X-X connecting the centers of the wheels 4, 5 generally coincides with the pipe axis direction of that portion. When the drive wheel 6 is rotated with a suitable rotation drive source such as a step motor under this condition, the whole device can be moved in the pipe axis direction.
    • 目的:通过提供一个夹紧力产生机构,在一个缩小夹角度的方向上激励一对手臂,允许一个装置自由地移动到一个管道内。 构成:两个臂1,2都不能抵抗由夹子力产生机构7产生的与管的内径相对应的通电力(f),因此,轮4,5被压到管道的一个表面部分8b 内壁面,另一方面,驱动轮6被反作用力压向与直径方向相反的另一个表面部分8a,从而可以最终在管道8中架设和稳定该装置。此时,方向 连接轮4,5的中心的XX通常与该部分的管轴方向重合。 在这种情况下,当用适当的旋转驱动源(例如步进马达)使驱动轮6旋转时,整个装置可以沿管轴方向移动。
