Description

Hull stopping device for split hopper barge

Technical Field

The utility model relates to a to open hull structure field of refuting mud, concretely relates to a hull detent for opening mud barge.

Background

The open body dredger is an advanced auxiliary ship for carrying, throwing and unloading dredged soil, and is mainly matched with a grab dredger for construction and loading. The split hopper barge consists of two longitudinally symmetrical half ship bodies, and the two half ship bodies rotate around deck hinges respectively under the action of an opening oil cylinder to realize the opening and closing of the left half ship body and the right half ship body. Therefore, deck hinges, which are the main stress points of the whole ship, bear very large loads during the opening and closing of the barge, and particularly the external dimensions and the mud tank capacity of the split mud barge in China are increasing continuously at present. Due to the buoyancy of water, the two half-and-half ship bodies tend to be opened particularly under heavy load, so that the two half-and-half ship bodies are prevented from being freely opened. Although the open body oil cylinder is restrained and locked, when the ship is transported in full load or has large stormy waves, certain deformation or dislocation tendency is generated between the ship bodies, and the damage to the open body oil cylinder and the deck hinge is large.

In order to solve the above problems, we have made a series of improvements.
