摘要本次毕业设计主要是对10t港口门座起重机的机械设计。随着社会经济的快速发展，港口贸易交流的发展方兴未艾，古代的运河漕运，近现代的江海水运，都演绎着港口经济对社会发展的不可或缺；江苏省的沿江开发、沿海大开发，更加诠释了江海联动发展的美好前景。待深发掘的巨大海洋经济也是以港口为载体的，港口门座起重机作为港口经济中一个关键环节，其重要性自然不言而喻。这次毕业设计主要对港口门座起重机的四大主要机构——起升机构、旋转机构、变幅机构、以及运行机构，进行了原理探讨分析和设计计算，并且对其分别绘图，同时也以上海港机厂M10-30型起重机为参照，绘制了10t港口门座起重机的总图和涉及的一些重要的零件图。在论文中也专门对港口门座起重机的安全装置进行了分类和讨论。49059

Abstract The graduation project is the mechanical design of the 10t port portal cranes.With the rapid social and economic development,the development of the port trade exchange is in the ascendant. Ancient canal water transport,modern river and sea transport,  demonstrating the interpretation of the port economy is an integral part of social development; Riverside development in Jiangsu Province、coastal development, show more interpretation of the the Jianghai linkage beautiful prospects, Great marine economy in deep excavation is to port as the carrier, Port gantry crane as the port economy, a key link, Its importance is self-evident natural. The graduated design of the main portal cranes of the port 's four major institutions——Hoisting mechanism、Rotary mechanism、Luffing mechanism、and the operating agencies, carring on the principle discussion analysis and the design calculation and its drawing respectively, but also as a reference to the Port of Shanghai Factory M10 -30 type crane, draw the diagram of 10t port gantry cranes and involved in some important parts diagram. In the paper I also specifically port gantry crane safety device classification and discussion .
