Embodiment Construction

[0031] Below in conjunction with the accompanying drawings and specific implementation cases, the method for leaving the cabin of the ship's main engine overhaul of the present invention will be further elaborated in order to express the structural features and specific applications of the present invention more clearly, but it cannot be used to Limit the protection scope of the present invention.

[0032] A method for getting out of the cabin for overhauling a main engine of a ship, comprising the following steps:

[0033]Step 1: Open a hoisting hole on the hull, mark the first positioning point 1 on the upper surface of the 03 deck, the first positioning point 1 is the intersection of the vertical line passing through the center of gravity of the main engine 2 and the 03 deck, and place the first positioning point Point 1 is shifted 1400 mm toward the stern of the ship to obtain the second positioning point 3, and the second positioning point 3 is shifted 460 mm to the port ...

Abstract

The invention discloses an out-of-cabin method for overhauling of a ship main engine and belongs to the technical field of ship construction. The out-of-cabin method comprises the following steps thatfirstly, a first set of hoisting holes, a second set of hoisting holes and a third set of hoisting holes are formed in a hull; secondly, the main engine is hoisted from the interior of a main enginecabin to a deck of a helicopter hanger through a first crane; thirdly, through alternate hoisting of the first crane and a floating crane, the main engine is moved into the helicopter hanger; and fourthly, through a winch, a channel steel rail and a carrying trolley, the main engine is moved to a flight deck. The out-of-cabin method is easy to grasp, the time and labor are saved, the workload of out-of-cabin operation of the main engine is reduced, and the defect that the main engine is prone to being damaged due to the fact that other methods are used in the out-of-cabin process can be avoided; and the out-of-cabin method has the characteristics of being easy to operate, safe and reliable, can be applied to overhauling out-of-cabin operation of the 3000 T ship main engine and can also beused for reference for civil ships.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a cabin-exiting method for overhauling a main engine of a ship. Background technique [0002] At present, China has become a major shipbuilding country in the world, and all kinds of ships have also entered the stage of intensive construction and modification. During the whole life cycle of the ship power platform, the main engine will be overhauled due to various reasons. When the main engine is out of the cabin, the traditional method is to open an opening larger than the main engine on each deck above the main engine, and lift the main engine to the ship cabin through the opening. This method of taking the main engine out of the cabin will cause great damage to the hull of the ship. At the same time, due to the arrangement of weapons and equipment such as the ship's outdoor radar, the way of large openings in the structure is often difficult to carry out due...
