Cargo hold cover for large ship

Abstract

The invention discloses a cargo hold cover for a large ship. The cargo hold cover is arranged on a cargo hold wall. The cargo hold cover comprises two cover plates, and the upper ends of the two cover plates abut against each other; a sealing part is arranged between the upper end parts of the two cover plates; the cover plates are hinged to the top of the cargo hold wall; a containing cavity is formed in the upper portion of the cargo hold wall, and a hydraulic oil cylinder is arranged in the containing cavity. The lower end of the cover plate is hinged to the top of the hydraulic oil cylinder. The hinged part of the cover plate and the cargo hold wall is positioned on the lower end part of the cover plate; a first stop collision block and a second stop collision block are further arranged in the containing cavity. A shielding space can be provided for marine transportation of large-scale goods with irregular shapes, the probability that the goods are damaged by disaster weather can be obviously reduced, and the goods are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a cargo hatch cover for large ships. Background technique [0002] Conventional traditional transport ships generally transport conventional bulk cargo, containers and other cargo. Large cargo hatch covers are generally lift-off, single-pull, folding, side-moving or back-loading, which can solve the vertical transportation of cargo. However, when the size of the cargo gradually increases and the shape is irregular, and special operations are required, the traditional cargo hatch cover cannot meet the hatch closing, shielding and protection requirements of the new type of large-opening cargo tank, and a larger-scale cargo hatch cover is required to meet the corresponding requirements. cargo hold. [0003] Existing ships equipped with equipment such as tethered balloons and transporting super-large cargo, all use the open air for cargo transportation. Long-term exposure in the open...
