Abstract
PURPOSE:To reliably pass through a deformed portion by coupling the above guide wheel for a transport pipe for gas or the like to a truck by a universal joint, supporting the right and left outsides of the guide wheel on the pipe wall by casters, and supporting a guide rope extended in the pipe at a height of an axle by a rope guide mechanism. CONSTITUTION:At the time of passing through a modified portion R, X' portion of a guide rope on the advancing side of a tow truck or a working truck A is held at the substantially center position in the pipeline by a guide wheel C. In this case, the distance between coupling points of the trucks A, B and the guide wheel C, that is, the distance between the center points (i), (i) of coupling means 12, 18 is set considering the curve of a deformed portion R of the pipeline in such a manner that the truck A and the guide wheel C will not interfere with each other. The guide wheel C is kept from falling down sideways by casters to pass through the deformed portion R. Thus, the guide wheel can be passed through the deformed portion reliably and easily.
