Cross beam structure of pure car/truck carrier

Abstract

The invention relates to a cross beam structure of a pure car / truck carrier. The cross beam structure comprises flexible longitudinal girders, a planking T-shaped platform, a deck cross beam and broadside cross beams, wherein the deck cross beam is connected between the two flexible longitudinal girders, the outer side of each flexible longitudinal girder is connected with one end of the corresponding broadside cross beam, the broadside cross beams are arranged in a left-and-right mode, the other end of each broadside cross beam is connected with the planking T-shaped platform, the deck cross beam is arranged between the two broadside cross beams, and the deck cross beam, the broadside cross beams and the flexible longitudinal girders are fixedly connected through welding. The cross beam structure of the pure car / truck carrier has the advantages that the cargo space is released, and the automobile placement quantity is increased by 10%; parking can be easier and quicker, loading and unloading of automobiles are quickened, the structure is simpler, the manufacturing material is saved, the manufacturing cost is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a cross beam structure of an automobile ro-ro ship. Background technique [0002] The ro-ro ship is also called the "up and down" ship, or the "roll up and down" ship. It is a special ship that uses freight vehicles to carry goods. A transport vessel that is loaded and unloaded directly into and out of the cargo hold by a trailer or wheeled pallet. [0003] Car ro-ro ship (PURE CAR / TRUCK CARRIER referred to as PCTC) car ro-ro ship is a special cargo ro-ro ship specially loaded with rolling stock. There are locators on the cargo hold deck for fixing containers or trailers. [0004] Car ro-ro ships, like container ships, have high loading and unloading efficiency, can save a lot of loading and unloading labor, reduce ship berthing time, and improve ship utilization. It also has advantages over container ships, that is, there is no need for lifting equipment on the dock, and there is ...

AI Technical Summary

Problems solved by technology

The disadvantages of this design method are: additional transverse structure is required to ensure the strength, and when double columns are used, the location of the ramp is relatively strict; the structure is relatively complex, the production time is long, the cost is high, and the vehicle is hindered when loading and unloading Many, complex travel routes, time-consuming, inconvenient, and a serious waste of space in the cargo area, so the space cannot be used rationally
