攀枝花学院本科课程设计（论文）机械动力滑台PLC控制系统设计学生姓名：王文强学生学号：2院（系）：机械工程学院年级专业：2011级机械设计制造及其自动化指导教师：助理指导教师：二0一四年十二月摘要机械动力滑台在先进制造领域中扮演着极其重要的角色。因其有着进给量稳定，慢速无爬行，高速无振动，有良好的抗冲击能力，以及没有液压驱动的管路，泄露，噪声，更便于维修的优点，而应用于我们的制造生产中，为我们生产加工零件带来了方便。本文通过对机械动力滑台的电气控制、PLC的设计，采用整体化的设计思路，充分考虑了软、硬件各自的特点并进行互补优化。对系统的输入输出信号的选择、PLC机型选择及各主要电器的选择都进行了最优化的选择。最后提出了一种简单、易于实现、理论意义明确的控制策略。关键字：机械动力滑台，可编程控制器（PLC），控制电路，I/O端口AbstractAlsoknownthehoistanothernameiswinch.Verticalliftingtransportmachineryisanimportantcomponentofthetieinwiththederrick,mast,pulleyblocks,andauxiliaryequipment,usedtoenhancethematerials,installationofequipmentoperations,fromhumanormechanicalpower-drivendrum,windingtractionropetocompletetheinstallationwork.Vertical,horizontalorinclinedsimpletractorLiftingheavyobjects.Twotypesofthehoistaremanualandelectrictwokinds.andNowtothemainelectricwinch.Thedesignofthe5-tonelectrichoistmotorcontionselectromotor、coupling、arrester、retarder、drum、boomsheave、asystemofpulleysset、hook,etc..Thedesignofthedrummachinebecauseofitssimplestructure,handlingtheinstallationofaflexible,convenientoperation,simplemaintenance,andoperatingenvironmentfeaturessuchasadaptability,canbeappliedtoliftingmetallurgical,construction,operationsandotherwaterconservancy,butthedesignmainlyappliedtothedrummachinefor5-tonoverheadcranehoistingmechanism.Heavywinchupgradeisoneofthemainfunctionsofthedesignofvarioustypeswinchesofarebasedonbasedonthisrequest.KEYWORDS:hoist，drum，drum，shaft目录摘要...............................................................Abstract............................................................................................................................................I1系统控制方案的确立.............................................................................................................01.1机械动力滑台工作方式...................................................................................................01.2采用PLC控制机械动力滑台的优点....................
