Title:
ATTITUDE CONTROLLER FOR SUSPENDED LOAD
Document Type and Number:
Japanese Patent JP3019673
Kind Code:
B2
Abstract:
PURPOSE: To control the attitude of a suspended load with high responsiveness by the strong jet propulsion force, without utilizing the large-scale equipment mounted on a suspending jig.
CONSTITUTION: A compressed air tank 8 is mounted on a suspending jig 1 which is suspended at a nearly horizontal attitude by a wire rope, etc., and each jet nozzle 9 is arranged at least at two positions of the suspending jig 1, and the compressed air in the tank 8 is jetted from the jet nozzle 9 through an opening/closing valve 10, and the suspending jig 1 is turned in the nearly horizontal plane by the jet propulsion force. A control part which detects the direction angle of the suspending jig 1 and controls the opening/closing valve 10 according to the difference between the direction angle and the target direction angle, and controls the turning operation of the suspending jig 1 so that the difference becomes min. is installed.
