Description

Bridge type ship loading and unloading machine

Technical Field

The invention relates to loading and unloading machine equipment for ports and docks, in particular to a bridge type ship loader and unloader capable of loading and unloading materials at a dock.

Background

Ship unloaders are used in many ports and docks for loading and unloading materials, especially in some thermal power plant docks. With the increasing demand for energy in China, the loading and unloading capacity of materials at docks of thermal power plants in various regions is increased day by day, and the thermal power plants also put higher requirements on ship unloaders and supporting equipment at the front edge of the docks.

In the prior power plant, materials are unloaded from a ship into a hopper of a ship unloader through the ship unloader, are conveyed to the rear through a ground belt conveyor, and are stacked into a rear material storage field through a stacker-reclaimer. When the ship is to be loaded, the material is taken from a rear storage yard by a stacker-reclaimer, is transported to the front edge of the wharf through the reverse rotation of a ground belt conveyor, and then is loaded by a ship loader at the front edge of the wharf.

This operation mode to material loading and unloading needs to add a shipment machine again at the pier front edge, and the increase of shipment machine has then influenced the working distance of ship unloaders, simultaneously, because the pier belt feeder still need just reverse, makes the belt off tracking easily, influences the transportation operation of loading and unloading, therefore fails to popularize and apply.
