Research progress and design calculation method of pipe conveyor
摘要
Abstract
Pipe conveyor is a kind of special belt conveyor which has extensive attention and has been widely used in recent years.Firstly,the structural design and improvement,design calcula-tion method,theoretical research and test of performance for pipe conveyor were reviewed.Sec-ondly,the relationship between the belt width and the pipe diameter,the bending performance and the running resistance of the belt w ere analyzed and the development trend of circular pipe belt conveyor was combed by summarizing the examples and research progress of the pipe belt conveyor domestic and abroad.Since the design mechanism and the belt characteristics were con-fused,the forming force could be used to characterize the bending performance of the belt or the transverse bending stiffness of the conveyor belt mechanically.The transverse bending stiffness of the conveying belt couldn't be directly reflected by the contact force for the gravity action of con-veyor belt.Thirdly,a formula for calculating lap width,according to actual application and rec-ommended by CEMA,of conveyor belt was put forward by the bandwidth and diameter ratio, which the excessive width of laps was simulated with the domestic standard.Finally,a new method,considering belt thickness and lap width,to determine the width and diameter of the pipe conveyor was provided because the diameter of pipe was presented by the outer diameter but the cross-sectional area of the bearing material was influenced by the belt thickness,and the cal-culation formula of pipe resistance,forming resistance and bending resistance of pipe conveyor was presented.The provided method and influence factors including transverse stiffness and forming force are applied in the engineering design of pipe conveyor,w hich is closer to reality than the existing methods.It provides a basis for the further development of the pipe conveyor.关键词
