Abstract
The invention discloses a hydraulic nut installation tool of a large propeller of a container ship. The toolcomprises an inner ring 1 sleeving outside a hydraulic nut to be installed, and the outside of the inner ring and an outer ring form a bearing structure through rolling bodies. A hoisting lug 10 is arranged on the outer ring. Jackscrews butting towards inner diameters are arranged through threaded holes on the ring wheel, beyond the two sides of the outer ring, of the inner ring. The tool can adjust the axis of the hydraulic nut and allow vertical and horizontal movement of the axis of the hydraulic nut. Adjusting jackscrews tightly clamp hydraulic nut of the propeller on the condition that the screwing axis is adjusted to allow the hydraulic nut of the propeller to rotate around a preset central line. The hoisting lug is fixed above a working area where the hydraulic nut of the large propeller of the container ship needs to be installed. The hydraulic nut installation tool of the large propeller of the container ship improves installation efficiency and accuracy of the hydraulic nut and lowers work intensity and dangerousness during the installation process, thereby being suitable for hydraulicnut installation of the large propeller of the container ship.
