With the development of science and technology and the rise of distance on the conveyor and the traffic has a new and higher requirements, our design of a large belt still in its infancy, the belt conveyor design, manufacture and applications, advanced level in China and abroad, there is still a large gap between domestic manufacturing belt in the design process there is much to be desired. Thus, large transportation machinery, especially the belt conveyor design theory and methods of in-depth analysis is necessary.
This article was flexible belt conveyor design the overall structure and to determine given the major components of the conveyor structure parameters and their calculation. Designed according to the given parameters and calculate the standard belt use scalable components constitute a fixed level of the transport belt conveyor machine, used in a hydraulic tensioning device automatically adjusts the device, and make the main parts the strength analysis.
Under the belt and the part of the characteristics of the main component, the first part of its drive to design calculations, and then select the appropriate drive, and finally determine the tensioning device of the structure and design calculation was carried out.
The design is mainly used for coal mine transport, considering all factors, adopt a reasonable driving scheme, means braking and soft start device combination, effective to ensure reliable operation of the belt conveyor.
