摘要通过对国内起重行业需求的研究,在参考大量有关起吊设备的资料前提下,设计了一种适合于小型工厂或者实验室内的简易吊车;通过对各类起重机的分析,选择一种门座式起重机方案;设计出几种不同的门座式起重机方案,比较后选择一个最优设计方案:使用工字型钢作为主梁、方管为支撑架,通过焊接的连接方式形成主架;主运行机构为单轨运行小车,设计了一个小车来让重物可以进行水平横向移动,通过齿轮齿条驱动,齿轮通过一根轴连接圆环链链轮,最终可以使用人力拉动圆环链来完成重物水平移动的手动控制;副起升机构为手拉葫芦和支撑部分一套桁架结构;主架下部装有四个带锁的工业脚轮,可以推动支架让吊起的在室内纵向移动;同时进行了单轨运行小车零部件的设计计算;并且对钢结构的主梁受力做了深入的理论分析、计算和校核;利用AutoCAD和Solidworks软件,进行计算机辅助设计,实现起重机总体结构零部件的三维造型和工程图的绘制;再使用Abaqus对部分零部件的强度、刚度进行有限元分析;最后再对方案进行优化。63545

Title A three-dimensional design of simple hanger frame
Abstract Design a simple crane suitable for small factories or laboratories by lifting the domestic industry needs research and reference to a number of information about the premise of lifting equipment; Through the analysis of various types of cranes, choose a program of gantry cranes; Design several different programs gantry cranes, compare and choose an optimal design; Use the joist steel as the main steel beams, square tube support bracket are connected by welding to form the main frame;The main running organization monorail trolleys, designed a car to make the heavy horizontal lateral movement can be carried through the rack and pinion drive gear shaft is connected via a ring chain sprocket, eventually pulling ring chain can be used to complete the human horizontal movement of heavy manual control;Auxiliary lifting hoists and organizations to support part of a truss structure; The lower part of the main frame with four lockable industrial casters, can push bracket allow longitudinal movement in the room lifted;At the same time a monorail trolleys parts of the design calculations; and steel girders for the force to do a thorough theoretical analysis, calculation and check of; The use of AutoCAD and Solidworks for computer-aided design, the overall structure of the crane components to achieve three-dimensional modeling and engineering mapping; Abaqus for re-use some parts of the strength and stiffness of the finite element analysis; Finally,Optimizing the program.
