学士学位论文液压起重机变幅系统设计摘 要随着经济建设的飞速进展，我国的基础建设力度正逐渐加大。道路交通、机场、港口、水利水电、市政建设等基础设施的建设规模也越来越大。市场上液压起重机的需求也随之增加。液压起重机是各种工程建设广泛运用的重要起重设备。它是用来对物料进行起重、运输、装卸或安装等作业的机械设备。作为主要施工机械在工业和民用建筑中得到广泛运用。它对减轻劳动强度、节约人力、降低建设成本、提高施工质量、加快建设速度、实现工程施工机械化起着十分重要的作用。本设计的主要任务是查阅相关的资料和文献，确定起重机变幅系统的方案以与变幅机构三铰点的位置。根据已知数据，对起重机的变幅液压缸进行设计和计算。根据计算的数据画 CAD 图纸。最后对变幅系统的其他主要元件进行选取。变幅系统中变幅液压缸的设计和计算是整个系统设计的重点。变幅液压缸的设计与计算主要参照《新编液压工程手册》和《机械设计手册》中的公式。关键词 液压起重机；变幅机构；变幅液压缸Hydraulic crane luffing system designAbstractWith the rapid economic development, China's infrastructure is enlarging gradually. Road traffic, airport, port, water conservancy and hydropower, municipal construction and other infrastructure construction scale is more and more. Market demand increases hydraulic crane. Hydraulic crane is an important hoisting equipment widely used in various engineering construction. It is used for lifting, transportation, loading and unloading and installation work on material mechanical equipment. As the main construction machinery in the industrial and civil construction has been widely used. It is to reduce labor intensity, save manpower, reduce the cost of construction, improve construction quality, speed up the construction, engineering construction mechanization plays a very important role. The design of the main tasks is to access relevant information and documents, to determine the three hinge luffing system of crane luffing mechanism scheme and the position. Acco...
