<P>PROBLEM TO BE SOLVED: To secure frictional force necessary for movement and achieve downsizing of a tip end device, to securely enable wire insertion into a building. <P>SOLUTION: A method for moving a cable passing apparatus includes: correcting a direction by operating a control electromagnetic valve 10 to supply and discharge compressed air to a direction correction device 4 (first step); controlling control electromagnetic valves 8A and 8B by a control device 11 to bring a sucking operation of a front part negative pressure absorber 1 into a stop state and to bring a sucking operation of a rear part negative pressure absorber 2 into an operation state (step 2); expanding an expansion device 3 by a control electromagnetic valve 9 to thereby move the front part negative pressure absorber 1 forward (step 3); while expanding the expansion device 3, operating the control electromagnetic valves 8A and 8B to bring a sucking operation of the front part negative pressure absorber 1 into an operation state and to bring a sucking operation of the rear part negative pressure absorber 2 into a stop state (step 4); and reducing the expansion device 3 in an expanded state to advance the rear part negative pressure absorber 2 (step 5). The steps are repeated to move a cable passing apparatus in any direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
