Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The embodiments are not intended to limit the scope of protection of the invention. Obviously, those skilled in the art can obtain other embodiments without having to pay creative work. Belong to the protection scope of the present invention.

[0022] combine Figure 2 to Figure 7 As shown, a bridge wing structure of an ultra-large ore ship includes a bridge wing deck 1 arranged transversely along the hull. Preferably, the bridge wing deck is vertically composed of double-layer plates. A vertical support 3 is fixed under the wing deck, and a wing brace 2) is fixed between the vertical support and the wing deck. Form a triangular structure horizontally. The support point where the wing brace 2 is connected to the wing deck 1 is close to the maximum width of the wing, and the angle between the wing brace 2 and the horizontal direction is greater...

Abstract

The invention relates to a bridge wing structure for an ultra-large ore carrier. The bridge wing structure for the ultra-large ore carrier comprises a bridge wing deck (1) which is placed in a transverse direction of a carrier body, wherein a vertical support (3) is fixedly connected under the bridge wing deck; a bridge wing diagonal bracing (2) is fixedly connected between the vertical support and the bridge wing deck; and the bridge wing diagonal bracing, the vertical support and the bridge wing deck form a triangular structure along the transverse direction of the carrier body. An angle between the bridge wing diagonal bracing and the horizontal direction is more than 45 DEG. The bridge wing diagonal bracing and the vertical support are both formed by plate stiffened structures. The bridge wing deck is formed by a double-layer plate in a vertical direction. Through the adoption of the bridge wing structure for the ultra-large ore carrier, provided by the invention, problems that the stiffness of a bridge wing is poor, the fixed frequency of the bridge wing is low and the bridge wing is prone to vibrate due to the overlong bridge wing can be effectively avoided. The bridge wing structure for the ultra-large ore carrier, provided by the invention, has the advantages of very high utilization value and significant using meaning.

Description

technical field [0001] The invention relates to a bridge wing structure, in particular to a bridge wing structure of a very large ore carrier (VLOC). Background technique [0002] Very large ore carriers are ships used to transport iron ore. In recent years, the demand for very large ore carriers has increased significantly. The excessive vibration of the ship will affect the comfort of the ship, the strength of the hull structure, the safety of navigation and the performance of the ship. Therefore, in structural design, how to reduce ship vibration has been paid more and more attention. Usually, the engine room and superstructure of the ship are arranged at the tail, close to the excitation source, which is the area with the largest excitation effect and the most important area for vibration assessment. [0003] It is a technical difficulty to solve the vibration of the bridge wing of the ultra-large ore carrier. Since the ship width of the VLOC is often large, the two wi...
