摘要：

圆管带式输送机是近年来受到广泛关注与应用的特种带式输送机。对圆管带式输送机结构设计与改进、设计计算方法、性能的理论研究与测试等进行了回顾；通过总结国内外圆管带式输送机实例和研究进展，分析了输送带宽度与管径的关系、输送带弯曲性能、运行阻力等方面的问题，梳理了圆管带式输送机的发展趋势。针对目前设计机理与输送带特性相关概念混淆的问题，从力学的角度明确了成形力、接触力（反弹力）、成槽性和横向弯曲刚度的关系，分析可知接触力包含输送带的重力，不能直接反映输送带的横向弯曲刚度，建议用成形力来表征输送带弯曲性能或横向弯曲刚度。根据实际应用和CEMA （Conveyor Equipment Manufacturers Association）推荐的输送带搭接宽度，指出了国内现行标准存在搭接宽度过大的问题，建议采用带宽管径比来表示带宽与管径的关系，并提出了搭接宽度的计算式。由于圆管带式输送机的圆管直径由外径表示，但输送带的厚度对承载物料截面积影响显著，给出了考虑输送带厚度和搭接宽度的确定圆管带式输送机带宽、管径的新方法及圆管带式输送机的成管阻力、成形阻力和曲线段阻力的修正计算式。所提出的计算方法考虑了输送带的横向刚度和张力等影响因素，与现有方法相比更接近于实际，且已经在圆管带式输送机工程设计中应用，为圆管带式输送机的进一步发展提供了依据。

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 calculation method, theoretical research and test of performance for pipe conveyor were reviewed. Secondly, the relationship between the belt width and the pipe diameter, the bending performance and the running resistance of the belt were 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 confused, 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 conveyor belt. Thirdly, a formula for calculating lap width, according to actual application and recommended 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 calculation 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, which is closer to reality than the existing methods. It provides a basis for the further development of the pipe conveyor.
Key words: pipe conveyor    conveyor belt    forming force    operation resistance
