Description

Technical Field

[0001] The present invention relates to the technical field of port and waterway engineering, and more specifically, it is a bulk cargo belt conveyor system for realizing two-way material transportation in a high-piled wharf. The present invention also relates to a conveying method for the bulk cargo inlet and the bulk cargo outlet of such a bulk cargo belt conveyor system for realizing two-way material transportation in a high-piled wharf. Background Art

[0002] Conventional high-piled wharves use ship unloaders and ship loaders, and arrange bulk cargo inlet belt conveyors and bulk cargo outlet belt conveyors to realize the loading, unloading and conveying operations of bulk cargo inlet and outlet. That is, the loading, unloading and transportation of bulk cargo in conventional high-piled wharves are two independent systems, and the bulk cargo inlet and outlet cannot be completed on the same belt conveyor; since only one ship can be berthed at the same berth of a high-piled wharf, it is impossible to carry out bulk cargo inlet and outlet loading and unloading operations at the same time. That is to say, in the two systems of bulk cargo loading, unloading and transportation at the same berth of a high-piled wharf, there is always one system in an idle state.

[0003] Based on this phenomenon, in order to effectively improve the conveying function and efficiency of the belt conveyor, reduce the number of belt conveyors in the high-piled wharf, and reduce the project investment, it is necessary to develop a belt conveyor system that can meet both bulk cargo inlet and bulk cargo outlet on the same berth and the same belt conveyor of a high-piled wharf.

[0015] Step 1: Tighten the vertical tensioning device of the quay face, causing the lifting and sliding legs of the quay face to slide to the left and retract downward. The lifting and sliding legs of the quay face move away from the transfer station, and the redirecting rollers of the quay face withdraw from the transfer station.
