Description

Technical Field

[0001] The present invention relates to a ship support mechanism, and more particularly to a composite support mechanism for supporting a lashing bridge and a ship superstructure. Background Art

[0002] For some feeder container ships, the living quarters including the cab are located in the mid-rear part of the ship. Containers are also loaded on the rear deck of the living quarters. And the shipowner has a need for a lashing bridge. Due to port restrictions and economic considerations, the ship length is not suitable to be lengthened within a certain specific range. Under the condition of meeting the requirement of passage width, the lashing bridge needs to be as close as possible to the superstructure of the living quarters in the design. In this case, the lashing bridge columns are usually very close to the upper deck, even with zero spacing, resulting in interference with each other.

[0003] Since the lashing bridge is too close to the containers, it is very difficult to operate the assembly of components such as tie rods and turnbuckles. And the lashing columns are too close to the deck supports. Even a slight deformation will cause interference, and in severe cases, it may cause deformation of the deck supports, thus affecting the structural safety of the hull. Summary of the Invention

[0004] By integrating the design of the lashing bridge columns and the superstructure columns, and using the lashing columns to support the upper deck of the superstructure, the present invention not only solves the problem of interference between the lashing bridge columns and the superstructure, but also ensures the lashing space for containers and the passage width. The specific solutions are as follows:

[0005] A composite support mechanism for supporting a lashing bridge and a ship superstructure. There is a lashing bridge and a superstructure composed of at least two decks on the hull. The lashing bridge and the superstructure on the side close to the lashing bridge share the composite support mechanism for support. The composite support mechanism includes an H-shaped steel and a square steel vertically welded to the hull. One side of the square steel extends into the grooves on both sides of the two web plates of the H-shaped steel away from the side of the ship superstructure. The two side edges of the square steel close to the inner side of the web plate are welded and fixed to the web plate.

[0006] The cross-section of the top of the web plate and the top of the square steel in the extending direction of the web plate is a right trapezoid. The inclined surface of the right trapezoid is arranged on the side close to the superstructure. Sealing plates are welded on both the horizontal plane and the inclined surface at the top of the web plate and the square steel.

[0007] Further, the model of the H-shaped steel is 220X200X10, and the model of the square steel is 300X200X12.

[0008] Further, the narrow side of the square steel extends into the groove on the side of the H-shaped steel away from the ship superstructure.

[0009] Further, the composite support mechanism is fixedly connected to the deck of the superstructure through a strengthening member including an elbow plate.

[0010] Furthermore, both sides of the lashing bridge are supported by several pairs of the composite support mechanisms, and each pair of the composite support mechanisms are fixedly connected through connecting gusset plates.

[0011] Furthermore, the weld seam between the side of the square steel and the wing plate in the vertical direction is an integral continuous weld seam.

[0012] The present invention further optimizes the hull structure and solves the problem of narrow and cramped space. Different from the traditional lashing bridge and the superstructure of the ship being supported by their respective support mechanisms respectively, the present invention designs a new composite support mechanism by combining square steel and H-shaped steel to provide support for both the lashing bridge and the superstructure of the ship at the same time. On the one hand, using H-shaped steel can allow the square steel to extend into the groove to reduce the occupied deck area. On the other hand, the H-shaped steel has relatively stable support and can meet the requirements of support stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0019] To thoroughly understand the present invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may have other embodiments.

[0020] Referring to Figure 1 as shown, the present invention provides a composite support mechanism 30 for supporting lashing bridges and superstructures on ships. A superstructure composed of a lashing bridge and at least one deck is provided on the hull. As Figure 1 shown, the superstructure area 10 is on the right side of the lashing bridge area 20. The upper deck 1 and the lower deck 3 are provided in the superstructure area 10, and the area between the upper deck 1 and the lower deck 3 serves as the crew activity area or the cargo hold area. Currently, the bottom of the lashing bridge is supported by lashing bridge columns, and the two decks in the superstructure area also need to be connected by support side walls. In order to maximize space utilization, the lashing bridge columns are often very close to the support side walls of the superstructure, resulting in easy interference.

[0021] To solve this problem, in the present invention, the lashing bridge and the superstructure close to the lashing bridge share the composite support mechanism 30 for support. The composite support mechanism 30 includes an H-shaped steel 31 and a square steel 32 vertically welded to the hull. As Figure 3 and Figure 4 shown, one side of the square steel 32 extends into the grooves on the sides of the two wing plates 31-2 of the H-shaped steel 31 away from the superstructure area 10 of the ship, and the two side edges of the square steel 32 close to the inner side of the wing plate 31-2 are welded and fixed to the wing plate 31-2. Since the composite support mechanism 30 of the present invention simultaneously bears the support of the lashing bridge and the superstructure mechanism, as Figure 1 shown, the left side of the composite support mechanism 30 is used to support the lashing bridge, and the right side serves as the support side wall 2 of the superstructure deck. On the premise of ensuring support stability, it is necessary to minimize the area occupied by the composite support mechanism 30 on the deck. Based on this consideration, the present invention extends one side of the square steel 32 into the groove on one side of the H-shaped steel 31, which can reduce the lateral occupied space. Preferably, there is preferably some spacing between the square steel 32 and the web 31-1 as deformation redundancy, as Figure 4 shown.

[0022] The cross-section of the top of the wing plate 31-2 and the top of the square steel 32 in the extending direction of the wing plate 31-2 is a right trapezoid (such as Figure 3 the top of the structure), and the inclined surface of the right trapezoid is arranged on the side close to the superstructure. The first sealing plate 33 and the second sealing plate 34 are welded to the horizontal plane and the inclined surface of the top of the wing plate 31-2 and the square steel 32 respectively. Since the present invention not only serves as the support of the lashing bridge but also as the deck support of the superstructure, and there will inevitably be a gap between the deck and the lashing bridge, it is necessary to set a sealing plate at its top to seal the top opening of the composite support mechanism 30 to play a role in waterproofing and dustproofing.

[0023] In an alternative embodiment, the H-beam 31 and the square steel 32 are made of common types of steel on the market. For example, the model of the H-beam 31 is 220X200X10, and the square steel 32 is a rectangular square steel with different lengths and widths, and the specific model is 300X200X12. Further preferably, the narrow side of the square steel 32 extends into the groove on the side of the H-beam 31 away from the superstructure of the ship, so that the long side of the square steel 32 supports the lashing bridge, ensuring that there is sufficient contact area between the square steel 32 and the lashing bridge, thereby improving the stability of the mechanism for supporting the lashing bridge. In addition, the composite support mechanism 30 is fixedly connected to the deck of the superstructure through a reinforcing member including gusset plates to improve the stability of the mechanism for supporting the superstructure of the ship.

[0024] In an alternative embodiment, both sides of the lashing bridge are supported by several pairs of composite support mechanisms 30. The bottom spacing of each pair of composite support mechanisms 30 is 650 mm, and each pair of composite support mechanisms 30 is fixedly connected by a connecting gusset plate 35.

[0025] In an alternative embodiment, the weld between the side of the square steel 32 and the wing plate 31-2 in the vertical direction is a continuous weld, and there is no break point in the welding from top to bottom, thereby ensuring the stability of the connection between the square steel 32 and the wing plate 31-2.

[0026] The preferred embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and the equipment and structures not described in detail should be understood to be implemented in a common manner in the art; any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes, which does not affect the essence of the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of protection of the technical solution of the present invention.
