摘　　要：长距离带式输送机在自然转弯过程中容易出现输送带跑偏等问题,主要纠偏方法是对转弯段托辊架的角度进行调整,但目前调整多为人工调整。文中通过设计一种可调整托辊架槽角和抬高角的自动纠偏系统,对机械结构设计、控制系统设计和传感器选型进行研究。机械结构设计方面进行了托辊架支撑体、推进装置与起升装置的结构设计和计算,控制系统设计方面进行了控制流程设计、驱动设计和传感器的设计与选型,最后进行了关键零部件的有限元分析和强度校核,分析了关键零部件在不同抬高角和不同槽角下的等效应力变化情况,为转弯段纠偏装置的设计提供了理论参考。The long-distance belt conveyors are prone to problems such as belt deviation at natural bending.The main deviation-correcting method is to adjust the angle of the idler frame,but at present it mainly relies on manual adjustment.In this article,an automatic deviation-correcting system is designed,which can adjust the idler frame’s groove angle and elevation angle;efforts are made to explore its mechanical structure,control system and sensor selection.In terms of mechanical structure,the roller frame’s supporting body,the propulsion device and the lifting device are subject to structure design and calculation.In terms of control system,the control process,the drive and the sensor are subject to design and selection.Finally,both the finiteelement analysis and the strength check are conducted on the key components,and the changes of the equivalent stress of the key components with different elevation angles and groove angles are analyzed,which provides theoretical reference for the design of deviation-correcting systems at bending sections.
