STRONG PROPELLING DEVICE FOR SPECIAL WORKING SHIP
Document Type and Number:
Japanese Patent JPS62225493
Kind Code:
A
Abstract:
PURPOSE:To improve efficiency of a special working ship by clamping a steel pole thrusted into the water bottom ground with a drive gear and a clamp gear, advancing an iron box mounted with the prime moving function with the hydraulic force, and tilting the steel pole to propel the working ship. CONSTITUTION:A steel pole is dropped into the water by its own weight with a claw 11 half opened by the water resistance, and it is landed to form a support point 10 and obtains the necessary ground support force. This steel pole 1 is completely clamped by the engagement of a drive gear 2 and a guide gear 3 and is thrusted by the action of a motor gear, an iron box 4 is advanced jointly by a drive device 17 and the hydraulic force of two tubes 19, 20, and the steel pole 1 is tilted to propel a working ship. When the tilt of the steel pole 1 proceeds, the steel pole 1 is electrically operated to be removed from the water bottom ground and is lifted, then the iron box 4 is returned to its original position, and the ship is propelled like a measuring worm by repeating these actions. Accordingly, working efficiency of the special working ship can be improved.
