Abstract
The invention relates to the technical field of ships, in particular to a vibration damping support structure for a large ship superstructure, which comprises a ship body main deck and a bridge deck, wherein two sides of the superstructure are respectively provided with a support frame body, and the support frame bodies are arranged between the ship body main deck and the bridge deck; each support frame body comprises a main support and two supports respectively, and the two supports are in a Y-shaped structure at the top of the main support. The bridge deck has a simple structure, has better strength for supporting the bridge deck, and improves the stability of the superstructure.
Description
Technical Field
The invention relates to the technical field of ships, in particular to a vibration reduction supporting structure for an upper building of a large ship.
Background
The development of large-scale and light-weight international freight ships is that for large cargo ships, the width of an upper-layer building is smaller than the width of a ship, the two wings of a bridge deck are required to reach the maximum width of the ship, the span is larger, the structure of the upper-layer building is weak, and the situation that the structural vibration exceeds the standard easily occurs at the two wings of the bridge deck. In addition, in the existing stage, in order to improve the energy efficiency level of ships, a propulsion system is developed towards the direction of low revolution and high efficiency, and the two wings of the deck of the bridge of the superstructure are more easily vibrated.
Disclosure of Invention
In order to solve the technical problem, the invention provides a vibration reduction supporting structure for a superstructure of a large ship, which changes the traditional structural supporting mode, adopts an independent box type supporting structure and improves the supporting strength.
The invention adopts the following technical scheme:
a vibration damping supporting structure for a superstructure of a large ship comprises a ship body main deck and a bridge deck, wherein two sides of the superstructure are respectively provided with a supporting frame body, and the supporting frame bodies are arranged between the ship body main deck and the bridge deck; each support frame body comprises a main support and two supports respectively, and the two supports are in a Y-shaped structure at the top of the main support.
Compared with the prior art, the invention has the beneficial effects that:
the bridge deck is supported by the box-type supporting structure independent of the superstructure, so that the bridge deck is supported with better strength, a reinforcing structure is prevented from being added in the superstructure, and the bridge deck can be prevented from exceeding the standard due to the stable structure.
Further, the invention adopts the following preferable scheme:
the main support is a box-type upright post, and each support is of an A-shaped box-type structure.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a support frame;
FIG. 3 is a side view of FIG. 2;
FIG. 4 is a schematic view of the present invention applied to a ship hull;
in the figure: a hull main deck 1; a superstructure 2; a bridge deck 3; a support frame body 4; a main support 41; and a support 42.
Detailed Description
The invention is further described below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a vibration damping support structure for a superstructure of a large ship mainly comprises a hull main deck 1, a bridge deck 3, support frame bodies 4 symmetrically arranged on two sides of the superstructure 2, and the like.
As shown in fig. 2 and 3, the support frames 4 are disposed between the main deck 1 of the ship body and the bridge deck 3, the support frames 4 are box-type supports respectively independent of the superstructure 2, and each support frame 4 mainly comprises a main support 41 and two supports 42. The main support 41 is a box-shaped upright post, the bottom of the main support 41 is welded on the main deck 1 of the ship body, steel plates are welded outside the main support 41, and reinforcing ribs are welded inside the main support. The side-looking appearances of the two supports 42 are respectively of an A-shaped box structure, the bottom end of one support 42 is welded to the top end of the main support 41, the top end of the other support 42 is welded to the farthest end of the bottom of the bridge deck 3, the bottom end of the other support 42 is welded to the top end of the main support 41, the top end of the other support is welded to the middle position of the bottom of the bridge deck 3, and the two supports 42 are of a Y-shaped structure between the bridge deck 3 and the hull main deck 1.
The bridge deck 3 is supported by the box-type supporting structure independent of the superstructure 2, the supporting strength is high, a reinforcing structure is prevented from being added in the superstructure 2, the stability of the superstructure 2 is improved, and the bridge deck 3 can be prevented from exceeding the standard due to vibration after the stability of the superstructure 2 is improved.
The above description is only for the specific embodiment of the present invention, but the protection of the present invention is not limited thereto, and all the equivalent changes or substitutions of the technical features of the present invention which can be made by those skilled in the art are included in the protection scope of the present invention.
Claims (2)
1.
