月色黯然本文介绍了起重机的发展和分类,对32/5吨桥式吊车小车进行了设计。首先对小车的总体结构进行了设计,其次分别对小车的主、副起升机构进行设计与计算,然后又对小车的运行机构进行了设计与计算,接下来是小车的卷筒、卷筒轴、齿轮等主要部件的选择与计算,并使用Auto CAD绘图软件进行了绘图,最后是小车总图的绘制和设计书的撰写。本次的论文设计使我对大学所学知识有了很好的巩固与提高,并为以后的工作打下了坚实的基础。
Abstract
Lifting machinery development has a long history，the description is increasing ,and has a widely use. In today’s every department of national economy, such as metallurgical ,machinery ,transportation, electric power ,construction and mining chemical defense, etc, all of those can without lifting machinery. With the development of scientific technology and the development of economic construction, It’s increasingly show hoisting machinery has a prominent place as a special equipment of the
mechanization of the production process to achieve, automation, reduce the intensity of physical and improve labor productivity .The structure of modern hoisting machinery has large precise efficient multifunction pleasant to the electromechanical of the development direction.
This paper introduces the development and classes of the hoist, and made a design for 32/5 ton’s gantry crane car. First of all made a design of the car total structure, followed by the master and deputy of lifting mechanism design and calculation, then the operation of institutions of car design and calculation, the next is the car’s roll, roll shafts ,gears and other major components of the selection and calculation, using the drawing software Auto CAD drawing, the last is the total car mapping and write the designed book. The thesis of this makes me a very good knowledge of the university is the consolidation and enhancement, and lay a solid foundation for future work. Key words: bridge crane, hoisting mechanism, traveling mechanism
