Method for installing marine energy-saving guide wheel and stern ball casting on flat ground

Abstract

The invention relates to a method for installing a marine energy-saving guide wheel and a stern ball casting on the flat ground, which comprises the following steps of: respectively carrying out original data acquisition on the stern casting and the guide wheel by using a total station, carrying out simulation analysis by using Block software, and calculating the clear amount of the guide vane according to the simulation data of the contact surface of the stern ball casting and the guide wheel guide vane, carrying out under-tire pre-cleaning on the guide wheel guide vane; the stern ball casting is independently subjected to tire raising on the ground; the guide wheel and the stern ball casting are preassembled, and the stern end face of the guide wheel in the preassembled state is about 4.5 m; part of guide vanes of the guide wheel are supported by supporting columns, and the supporting columns need to be vertically arranged; after the guide wheel is preassembled, the guide wheel and the stern ball casting are welded; hoisting the stern ball casting and the guide wheel assembly; the operation danger coefficient caused by high-altitude operation is reduced, and the hook occupying time of hoisting construction of a large crane is shortened.
