PROPULSION METHOD BY WIRE USAGE AIMING AT FORMATION OF LONG RANGE EXTENSION OF SELF-PROPELLED EQUIPMENT INSERTED INTO TUBE

摘要

PROBLEM TO BE SOLVED: To provide a long range propulsion method which effects longer propulsion distance extension over self-propelling capability of self-propelled equipment to proceed through the tube.;SOLUTION: The wire 15 that detects the self-propelled maximum propulsion position of the self-propelled equipment with a hose equipped with an electromagnetic wave transmitter to proceed through the tube 2 by jetting of hyperbaric pressure fluid 17, perforates the tube 2 by drivaging the position and hauls the self-propelled equipment at the position is fitted. The wire 15 is restored to the insertion port of the tube 2 to release it and fitted again to a somewhat shorter position than the self-propelled maximum distance to wind it at the drivaged point. The tube 2 is perforated by drivaging the proximity of the prong of the self-propelled equipment and the wire 15 is replaced to return it to the insertion port of the tube 2 again. The long distance propulsion method is operated by repeating a series of these operations.;COPYRIGHT: (C)2007,JPO&INPIT
