钢厂钢卷起吊装置机械CAD图纸设计.doc

摘 要 随着钢卷的广泛应用，起重机面临这巨大的市场需求。近年来，企业采用起重机进行吊运工作，对起重机械的设计计算方式需要不断的更新和改进、完善。使起重机械更趋于经济性、可行性、可靠性和安全性的方向发展。因此，研究起重机械的优化设计方法，对于提高起重机械的效率和质量具有重要的意义。本文钢卷起吊装置分析了起吊装置的吊具和起吊机构，对于30t左右的起吊装置进行了详细设计，在吊具的设计中大量的使用杠杆原理，以及丝杠的运用：对于起重机的咽喉设备——起升机构的研究，减速器、电动机、卷筒和制动器的设计选用，尤其是卷筒的设计更是包含广阔；最后选用三菱PLC控制变频器，保证控制系统操作灵活、安全可靠。 关键词：起吊装置，杠杆，吊具，起升机构 ABSTRACT With the wide application of crane steel coil， facing the huge market demand. In recent years， the enterprise uses the crane for lifting work， for lifting machinery design and calculation methods need to constantly update and improve， perfect. The lifting machinery more economy， feasibility， reliability and safety of direction. Therefore， study on the hoisting machinery optimization design method， to improve the lifting efficiency and quality is of important significance. In this paper， steel coil lifting device of lifting device and a lifting mechanism for lifting， about 30t lifting device for the detailed design， in the design of a lot of spreader using the lever principle， and the screw used for crane: the throat equipment -- lifting mechanism research， reducer， motor， and brake drum design selection， especially the drum design is to contain vast; finally selected Mitsubishi PLC control inverter control system， flexible operation， safe and reliable.Key words: lifting devices， leverage， spreader， lifting mechanism 目 录 1绪论----------------------------------------------------1 1.1本课题研究的意义----------------------------------------------------------------------2 1.2本课题研究的内容----------------------------------------------------------------------2 2 丝杆-螺母机构的计算及其校核-----------------------------3 2.1丝杠螺母机构----------------------------------------------------------------------------3 2.2 螺杆行程计算---------------------------------------------------------------------------3 2.3 电机功率N-------------------------------------------------------------------------------4 2.4螺杆受力计算---------------------------------------------------------
