Problems solved by technology

Therefore, at present, many inland river cargo ships do not have cargo hatch covers and use open transportation methods. When ships load loose coal, sand and other cargo, rainwater will intrude into the cabin, which will affect the quality of the cargo and form dust pollution to the environment.

Abstract

The invention belongs to the technical field of ship equipment and specifically relates to a cargo hatch cover for an arched ship. The cargo hatch cover for the arched ship comprises a plurality of cover plates; the cover plates are fitted on hatch coamings on the two sides of a hull in a movable manner; a plurality of pairs of guide rails are placed on the two sides in pairs, on the hatch coamings in the length directions from outside to inside; one cover plate is fitted on each pair of guide rails in a movable manner; and at least one cover plate can horizontally move to enter into another cover plate. The cargo hatch cover for the arched ship has the advantages that the position of the hatch cover of the ship can be movably adjusted according to the different loading positions of a shiploader under a loading condition; and that is to say that the hatch cover can be opened and closed at a fixed point without being completely opened; therefore, the operation convenience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of ship equipment, and in particular relates to an arched ship cargo hold cover for inland rivers. Background technique [0002] As a means of transportation, ships have the advantages of large cargo capacity and low operating costs compared with other modes of transportation. With the development of the economy, the environmental protection of ships in the transportation process has also received extensive attention. At present, most of the common cargo hatch covers used by ships are steel planar structures, which are supported on the hatch coaming by rollers. This hatch cover is not only heavy in structure, but also reduces the volume of the cargo hold and affects the loading of the ship. Therefore, at present, many inland river cargo ships do not have cargo hatch covers and use open transportation methods. When ships load bulk coal, sand and other cargo, rainwater will intrude into the cabin, affecting ...
