Background
Because of the small height of the dry side of the barge, the equipment for transporting bulk cargo (mainly iron ore and coal) suitable for ship unloading operation mainly comprises a bridge grab ship unloader, a gantry crane with a bucket, a catenary ship unloader and the like. The bridge type grab ship unloader and the gantry crane with the bucket all carry out grabbing operation through the grab bucket, so that periodic ship unloading operation is realized. The two types of machine type overall mechanisms are simple, reliable in operation and convenient in maintenance, but in the process of operation, dust is very large in the process of grab bucket discharging, although a spray dust suppression facility is adopted to control dust escape, a large amount of dust is still diffused under the action of wind power, so that great pressure is caused for environmental protection, and the machine type overall mechanism cannot be effectively used in an environment sensitive area.
The suspension chain type ship unloader is used for taking materials through the fact that the chain bucket is attached to the surface of bulk materials, the bulk materials are lifted through the chain and then unloaded into the cantilever belt conveyor, the drop height is small, dust generation is well controlled, and the environmental protection effect is improved. In addition, the operation process is full continuous operation, the average efficiency is higher than that of a bridge type grab ship unloader and a crane with a bucket gate, and the operation energy consumption is lower than that of the bridge type grab ship unloader and the crane with the bucket gate, so that the bridge type grab ship unloader and the crane with the bucket gate are widely put into use at home and abroad at present.
