Embodiment Construction

[0027] The shaft and rudder system installation process for 10,000-ton special multi-purpose ships is composed of the "double-fixed and central collection" launching process and the "underwater installation of shaft and rudder system" process.

[0028] 1. The main contents of the "double fixed collection" launching process:

[0029] 1) Pre-stage technical preparation and equipment preparation to ensure that the stern tube and rudder sleeve arrive at the factory on schedule.

[0030] 2) Pre-drawing wires: Pre-drawing wires are used in the construction and closing of ship engine room and stern sections. During the closing process, the deformation caused by welding is continuously measured with the axis as the reference, and corrected in time, so as to minimize the deformation caused by welding. The resulting deformation is kept to a minimum to ensure the correct position of the shaft and rudder lines.

[0031] 3) Formal shafting and rudder line stays: After the hull has been pe...

Abstract

The invention discloses a mounting process for shaft and rudder systems of a 10,000-ton class special multipurpose vessel, which comprises the following steps: a. before the vessel is launched, a center line of the shaft system and a center line of the rudder system are determined; b. a stern tube is positioned and poured with epoxy, the vessel is launched after a waterproof close board is arranged; and c. a screw shaft, a propeller, a tiller and a rudder blade are arranged. Through adopting the way, the mounting process for shaft and rudder systems of the 10,000-ton class special multipurpose vessel overcomes the inconvenience that the screw shaft, the propeller, the tiller and the rudder blade of the vessel are all placed on a slipway for installation before the vessel is launched in the prior art, and makes the vessel launch after the shaft line and the ruder line are determined and checked, thereby saving time for preparing the screw shaft, the propeller, the tiller and the rudder blade of the vessel, shortening the construction cycle of the vessel, improving the utilization rate of the longitudinal slipway for a ship-building unit to construct the vessel, and reducing the production cost.

Description

technical field [0001] The invention relates to a ship, in particular to a shaft and rudder system installation process of a 10,000-ton special multi-purpose ship. Background technique [0002] The 10,000-ton special multi-purpose ship is a multi-purpose ship with a total load capacity of more than 10,000 tons, which is used to transport grain, coal, ore, salt, cement and other bulk dry bulk cargo in bulk. The ship is designed as a single engine, single shaft system, and single rudder Arrangement form, the axis is parallel to the baseline and is located in the mid-longitudinal section of the ship, and the center line of the rudder stock is perpendicular to the axis. Usually, the shafting and rudder system of the ship need to be installed before the ship is launched, and the ship can only be launched after passing the inspection to the ship owner and ship inspection. That is to say, the shafting and rudder system of the ship are carried out on the berth or in the dock. The ...
