Problems solved by technology

Such a traditional approach not only wastes materials, but also greatly increases the construction period and labor costs
In the process of turning over, too much strengthening welding will also lead to the deformation of the thin plate segmented welding

Embodiment Construction

[0020] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings. This embodiment is only used to explain the invention, and it cannot be assumed that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.

[0021] The invention provides a thin-plate section turnover tool, which is used to support the thin-plate section for turning operation. It mainly includes: a main beam 10, a support beam 20 and three supports 30 supporting it.

[0022] refer to image 3 Shown, the structure of the main girder. It is set as a U-shaped closed box structure; ...

Abstract

The invention discloses a turn-over method for a cruise ship segment. According to the turn-over method, the cruise ship segment is arranged on a turn-over tool connected to form an L-shaped structure, and the cruise ship segment and the turn-over tool are connected through all lifting lugs on the edge of the turn-over tool and corresponding lifting lugs on the edge of the cruise ship segment. Thus, the cruise ship segment is lifted through an upper truck crane hook and a lower truck crane hook on a gantry crane, and the problem that when the cruise ship segment is turned over, the difficultycoefficient is high, and the deformation amount is large can be solved due to the fact that the cruise ship segment is supported by a main beam and a branch beam on the turn-over tool. According to the turn-over method, deformation of the cruise ship segment in the turnover process can be effectively reduced, the welding number of stiffeners can be reduced, the safety and efficiency of turnover operation can be improved, and the high applicability of the turn-over tool can be improved.

Description

technical field [0001] The invention relates to the field of cruise ship construction, in particular to a method for turning over sections of a cruise ship. [0002] technical background [0003] Cruise ships are known as the "Pearl in the Crown" in my country's shipbuilding industry, and they are high-value-added and high-tech ship products. Cruise is a high-end maritime tourism project that integrates aesthetics and comfort, and is known as a "mobile city on the sea". In order to meet the requirements of carrying passengers, the proportion of superstructure of cruise ships is much higher than that of other types of ships. At the same time, in order to meet the main weight index of cruise ships and the demand for aesthetics of cruise ships, the superstructure of cruise ships has high requirements for light weight and board thickness, so as to meet the requirements of weight control and aesthetics. During the segmental construction of the superstructure of a cruise ship, 5m...
