Embodiment Construction

[0019] Such as Figure 1 to Figure 3 As shown, the propeller installation process method, the specific steps are: A. Set up a temporary eye 1 for propeller installation on the ship's outer plate and deck area during the berth loading stage, and pre-hook the drag chain hoist 2 in advance; Step B 1. The ship 3 is towed into the launching barge 4, and the stern of the ship protrudes out of the launching barge 7.25 meters, and then the launching barge 4 is moved to the wharf in the first area, and its stern is 16.5 meters away from the wharf in the tenth area; step C, using a 150-ton tower crane 7 to move The propeller 5 is placed on the square barge 6, and the four corners are fixed with sealing ropes; step D, move the square barge 6 to the edge of the lower water barge 4, and use the height difference between the two to start using the 150-ton tower crane 7 and the 160-ton crawler crane 8 Cooperate with hoisting the propeller 5 to turn over; step E, hoist the propeller 5 to the ...

Abstract

The invention discloses a propeller installation technological method. The method is characterized by including the following steps that A, temporary eye plates for installation of a propeller are arranged in regions of a ship shell plate and a deck, and chain blocks used for installation and adjustment are hung on the temporary eye plates; B, a ship is dragged into a launch barge, and the launch barge berths to an assigned wharf region in a shifting manner; C, the propeller is placed on a scow through a tower crane, and the four corners of the propeller are fixed; D, the scow is moved to the edge of the launch barge, and the propeller is lifted through the tower crane and a caterpillar crane so as to be turned over; E, after the propeller is lifted to be in a vertical state, auxiliary lifting points of the caterpillar crane are detached; F, the chain block hung on a main deck is connected with the eye plate at the top of the propeller, a main tower crane lifting point on the propeller is removed after a belt is tightened, and the propeller is continuously lifted through the corresponding chain block; and G, the installation angle of the propeller is adjusted through the chain block hung on the ship shell plate. By the adoption of the propeller installation technological method, the problem that the propeller is difficult to install is solved, and the installation cost is reduced.

Description

technical field [0001] The invention relates to a propeller installation process method. Background technique [0002] In the construction of special marine engineering ships, the installation of the stern main propeller is one of the key projects. According to the guidance documents provided by the equipment manufacturer and the previous ship construction experience, the propeller is installed during the construction stage of the berth, and the installation method is lifted from the lower part of the ship. Due to the large volume and high height of the equipment itself, the propeller cannot be installed directly on the berth, and the berth needs to be rebuilt, which will greatly increase the installation cost of the equipment. Contents of the invention [0003] The purpose of the present invention is to provide a propeller installation method that solves the difficult problem of propeller installation and reduces installation costs. [0004] The technical solution adopte...
