大型H钢翻转提升设计+CAD图纸

摘要本文阐述了大型H钢翻转提升机构的设计，设计包括了机械结构设计和控制系统设计两部分。机械结构部分采用了链式翻转、液压提升的结构组合。包括传动系统设计、翻转机构的具体设计、液压缸的设计等。控制系统采用了液压和机电结合的方式，利用液压控制系统的提升，机电控制系统的翻转操作。控制系统采用的是PLC控制。47274

首先调研收集分析有关资料，了解同类设备目前的发展状况，其次再进行机构的大体结构及其零部件的参数的初始拟定，然后对机构的零部件进行强度校核，如不满足要求改进设计。当机构的零部件满足要求时，对整个机构控制系统进行设计。最后画出零件图及总装图。

Abstract This text elaborated the large H steel inside out promote the design of the mechanism, the design included the machine structure design and the system design two fractions of control.The machine structure fraction adopted the type of chain inside out, the structure assemble that liquid presses to promote.The concrete design, liquid that designs the contents to include the drive system design, inside out mechanism presses design etc. of the urn.Control the system adopts the liquid to press and the mode of the machine electrical twinning, make use of the liquid to press to control the system to promote, inside out operation of the machine electric control system.For the sake of the step - down cost of the system, control what system adoption is a relay control but is of control of PLC.

First I collect and analyze relevant information, understand the current state of development of similar equipment, Followed by the initial parameters of the institutional general structure of their parts and components prepared, then check it’s strength. When meet the requirements ,design the control system of entire organization.Finally draw the part drawings and assembly diagrams.
