Problems solved by technology

The complete availability of shaft and rudder components will not only prolong the ship construction period, but also reduce the utilization rate of the longitudinal berth for ship construction, which will have a great adverse effect on the production of shipbuilding units.

Embodiment Construction

[0027] A multi-purpose ship shaft and rudder system installation process is composed of the "double fixed and middle collection" launching process and the "underwater installation of the 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 penetrated and all major ...

Abstract

The invention discloses a process for shafting and rudder system installation of a multi-purpose ship. The process includes a step a of determination of a shafting center line and a rudder system center line before ship launching; a step b of stern tube positioning and epoxy casting, installation of a waterproof closure plate and ship launching; and a step c of installation of a tail shaft, a propeller, a rudder stock and a rudder blade. The process for shafting and rudder system installation of the 10000-ton special multi-purpose ship is in such a mode such that the problem that in the priorart, the ship tail shaft, the propeller, the rudder stock and the rudder blade must be all complete on a shipway before the ship launching to be installed, so that inconvenience is caused is solved; after the shafting and the rudder system are determined and undergo inspection on the shipway, the ship launches, the time of preparing the ship tail shaft, the propeller, the rudder stock and the rudder blade is saved, the ship building cycle is shortened, the utilization rate of a longitudinal slipway of the ship built by a ship building unit is improved, and the manufacturing cost is reduced.

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 ...
