초록 ▼

Apparatus for remotely controlled movement through linear and curved sections of a pipe, or other tubular conduit. The apparatus includes a pair of members spaced apart along a common, central axis. Each member carries a plurality of extensible and retractable pneumatic cylinders for movement of frictional engagement elements into and out of engagement with the interior wall of the pipe. One or more axial drive cylinders rigidly connect the spaced members for movement thereof toward and away from one another. The apparatus carries equipment for inspecting, measuring and/or performing other operations on the pipe, and is of simple and economical design, requiring no gimbal joints or other special linkages for movement in the intended manner.

Apparatus for controlled movement through the interior of an elongated, tubular conduit having both linear and curved sections, said apparatus comprising, in combinatin: (a) first and second stepping members each including rigid frame disposed about a central axis, and frictional engagement mounted upon said frame and movable with respect thereto between outwardly expanded and inwardly retracted positions relative to said central axis; (b) means for moving said frictional engagement means of each of said stepping members between said outwardly extended and retracted positions for frictional engagement with and disengagement from the inside surface of said conduit; (c) axial drive means rigidly connecting said first and second stepping members in spaced relation for relative movement along said central axis; (d) said axial drive means comprising at least one extensible and retractable member rigidly connected at opposite ends to said rigid frames of said first and second stepping members, respectively; and (e) the frictional engagement of said engagement means with said inside surface of said conduit and the forces moving said engagement means to said outwardly extended position and moving said at least one extensible and retractable member to its extended position being such that: (i) said frictional engagement of said engagement means of each stepping member will support the remainder of the apparatus in spaced relation to said inside surface of said conduit, without significant slippage, during movement through linear sections of said conduit; and (ii) said frictional engagement permits slippage of said engagement means of each stepping member upon said inside surface of said conduit to permit limited rotation of said apparatus about an axis transverse to the axis of said conduit in response to movement of said extensible and retractable member to its extended position during movement through curved sections of said conduit.
