文章通过分析电动单梁起重机的几种不同主梁的截面类型来对电动单梁起重机进行研究,并将不同的起重机结构进行详细对比,从而了解不同结构的电动单梁起重机的优缺点。如箱形梁的特点是:其截面特性和承压性要比箱形工字的电动单梁起重机更优,其整体的构造,制作时所需要的工艺和流程也比箱形工字梁更为简便。不仅节约了制作的材料,而且机器的组装简单、使用起来也更加便利。截面为箱型的电动单梁起重机可以直接检测出待测主梁的向上拱起的度数,在生产中被更加广泛地使用。
In this paper, the electric single girder cranes are studied by analyzing the cross section types of several different girders of electric single girder cranes, and the different cranes are compared in detail to understand the advantages and disadvantages of electric single girder cranes of different structures. Such as the box beam is characterized by: its cross-sectional characteristics and pressure than the box-shaped electric single beam crane is better, the overall structure, the production process required more than the I-beam and more For simplicity. Not only does the material saved, but also the assembly of the machine is simple and easy to use. Electric single girder cranes with a box-shaped cross section can directly detect the degree of upward bowing of the girder to be measured and are more widely used in production.
