1、 毕业设计(论文) H3/36B 塔式起重机起升机构及臂架设计 摘要 塔式起重机在建筑行业运用很广泛,尤其是在高层建筑中,更是必不可少的起重运 料工具。本设计主要完成起升机构和臂架部分的设计,在查阅了大量文献和相关知识的 同时,掌握了大量的有关塔式起重机的知识后,模仿 H3/36B 型塔式起重机的起升机构 和吊臂而设计的。 起升机构是塔式起重机的最主要机构之一,尤其是传动装置减速器的设计尤为重要, 吊臂以及在其上面行走的变幅小车主要承担着运输重物的任务,因此要对其进行严格的 受力分析,并进行校核计算。由于吊臂结构承受很大的载荷作用且具有很大的危险性, 故选材和构件连接上要十分严格。与此同时,还
2、要考虑到材料的经济性,即造价成本问 题。 在借鉴前人经验和参阅相关资料的基础上,根据设计题目中给定的设计参数,将臂 架设计为正三角形水平桁架结构。 通过社会调查和技术经济性分析,本设计具有一定得实际应用价值和市场潜能,可 进行制造并投放市场。 关键词:塔式起重机,起升机构,吊臂,幅度,桁架 毕业设计(论文) The Lifting mecheanism and Arm of H3/36B Crane tower Design Abstract The crane tower is used in construct profession very extensively ,particular
3、ly in hign buildings,is also the essential tool to rise the heavy anticipates.This design primarily completes the design of lifting mechanism the arm part of crane tower.At checking the cultural heritage of large quantity and related knowledge at the same time,I complete the design by imitating the
4、lifting mechanism and the arm of H3/36B crane tower,after master lots of knowledge about the crane tower. The lifting mechanism is one of the important mechanism of the crane tower, particularly is the transmission device reducer .The arm and the amplitude running above it undertake the load primarily, therefore we must analyze the stress strictly, and check them by calculating.Because theconstruction of the arm bears the load applied to it and is wery dangerous to people,it
