Design And Implementation Of Control System For 90t Slab Clamp Crane

Steelworks within the slab yard cranes responsible slab storage, Shift and outbound operations. Crane cab drivers operate complete all operations, ground operations needed to confirm refers turner. Since the slab temperature is higher, the contents of a single work, poor communication with the turner and other reasons, crane operating rate has been affected and there are security risks. In addition, the ground means turner long slab radiant heat under the labor intensive, the job over time it is easy to cause heat stroke and other accidents. If we can achieve slab yard crane run automatically, either from the liberation of labor or to raise production efficiency has a greater significance in terms.In this paper, Gray bus positioning system and the existing slab library storage system based on the slab yard crane 90t slab clamp control system transformation. This paper describes the system design of core issues and key technology analysis crane step sequence runs automatically processes while lifting mechanism introduced to solve the gate opening control and carts load distribution problem. This development of open RS485 communication protocol to solve the crane positioning system with its own PLC system data communication problems, the control system by calling the automated storage system inside the location information, combined with Gray crane busbar system sends real-time location information to automatically generate a run-path, after the crane path generation to step sequence in the form of automatic positioning completion through multiple tasks to run automatically.Through the process of detailed analysis, using PLC, VC vector converter, Gray bus positioning system to complete the crane control system for automatic operation theoretical design, basically meet the crane automatically run the hardware and software conditions.
