Cargo ship

Abstract

A cargo vessel is provided to easily load long-cargos by moving a movable pillar and prevent loaded cargos from being fallen down by mounting the movable pillar after loading. A cargo vessel includes a plurality of supporting pillars(13) and a lifting deck(30). The pillars are perpendicularly mounted between peripheries of a side end of a hatch of an upper deck(5) and a side end of a hatch of a second deck(3). The lifting deck is arranged between the supporting pillar and a vessel frame(12) and is lifted between middle and upward positions. The supporting pillars are composed of fixed pillars(14) and movable pillars(15). The fixed and movable pillars are spaced apart from each other at a horizontal interval. The movable pillar has a lower end part inserted in a lower supporting frame formed at the periphery of the side end of the hatch of the second deck and an upper end part inserted in an upper supporting frame of the periphery of the side end of the hatch of the upper deck.

Description

technical field [0001] The invention relates to a cargo ship. In more detail, it refers to general cargo ships that transport long-dimension cargo such as general general cargo, automobiles, containers, pipes or steel products. Background technique [0002] The prior art example 1 shown in FIG. 14 is a central longitudinal sectional view of a double deck cargo ship. The lower cabin 101 and the upper cabin 102 are separated by a second deck 103 , and a box-shaped hatch (pontoon hatch) 104 is erected on the central opening of the second deck 103 . A hatch 106 is formed in the central opening of the upper deck 105 and can be covered with a hatch cover 107 . The above-mentioned box-shaped hatch cover 104 is a steel cover on which automobiles and the like can be loaded. Therefore, the double-deck cargo ship can carry out mixed loading of mainly loading heavy objects such as steel materials and equipment in the lower hold 101, and loading general cargo and automobiles in the up...

AI Technical Summary

Problems solved by technology

[0007] However, in the above-mentioned prior art example 3, there are still the following problems: how to effectively load long-dimension materials such as steel or pipes; the support columns of the middle deck hinder cargo loading, but the strength of the lifting deck cannot be maintained when it is cancelled, How to solve; how to fix the middle deck firmly in the raised position and lowered position, and make the movement simple when raising and lowering
