Description

Straight arm fixed ship unloader for dry bulk cargo ship

Technical Field

The invention relates to a ship unloader, in particular to a straight arm fixed ship unloader for a dry bulk cargo ship.

Background

The transfer platform is used for transferring dry bulk cargos of a small ship to a large ship through the transfer platform or transferring the dry bulk cargos on the large ship to the small ship through unloading equipment of the transfer platform.

The simplest lightering operation is to use a self-contained crane on the dry bulk carrier, which can be unloaded from a feeder ship moored together, into its own hold, or from its own hold, to remove cargo from the hold onto another ship moored together. Normal refuting takes two forms, one where the platform itself does not have warehousing capabilities, and another where the platform itself does. The two types of cargo are unloaded by the ship on one side of the platform, the cargo hold on the other side of the platform crosses the unloading equipment of the platform, the crane is more adopted, the crane is arranged on one side of the platform, the ship loader is arranged on the other side of the ship board, the crane dumps the cargo into the hopper on the belt conveyor, and the cargo is loaded onto the ship through the belt conveyor and the ship loader. The crane arm of the crane is a flexible link mechanism, and the displacement of goods can be realized only by the limitation of the arm length and the rotation, so that the capacity and the efficiency are low, the service ship type is limited, and the waiting time for feeding the ship and the loaded ship is long. The other is that it adopts bridge ship unloader, which is installed on deck track of modified cargo ship with storage facility, and the crane arm of bridge ship unloader is long, in which the crane carriage is linearly reciprocated, so that it has large capacity, high efficiency, and can cover all ship types, but it also has the disadvantages of high cost, high energy consumption and high requirement for working condition.
