塔式起重机附着装置的设计(含CAD图)(任务书,论文说明书1800字,CAD图22张)
摘要
塔式起重机是一种工程建筑中应用比较广泛的机械设备。随着我国经济社会的快速发展，对摩天大厦的高度要求提出了更大的挑战，这就要求塔机的工作高度要求更加严格。对于近百米高的塔机，其附着装置的有效性和安全性必须得到保证。
本文以附着塔式起重机为研究对象，详细地介绍了国内外塔机及其附着装置的发展背景。阐述了塔机附着装置的分类、构成以及作业要求，附着装置的组成部分一般分为附着框架、附着撑杆和附着连接基座。对塔机附着装置完成了设计，完成附着装置所承担的水平附着反力和扭矩的计算，计算每根撑杆的长度和最大内力，验算撑杆强度。对塔机附着装置的进行有限元静力学分析，对几个典型工况进行分析，查看了各附着撑杆承受的内力、应力及塔身最大位移，得到最高层附着装置承受的力最大的结论。为保证附着装置的有效性和塔式起重机的安全性提供了理论参考。

Abstract
Tower cranes are an engineering building used widely in machinery and equipment. With the rapid development of China's economy and society, of the skyscraper height requirements poses a greater challenge, which requires the work of the tower crane height requirements more stringent. For nearly a meter-high tower crane, the effectiveness and safety of the attachment means must be guaranteed.

    In this paper, attached tower for the study, detailed description of the background of the   development of domestic and international tower crane and attachment means. Describes the classification tower crane attachment means, composition and operational requirements, part of the attachment means attached to the framework are generally divided into, and attachment attachment struts connect the base. Tower crane attachment means complete design, complete attachment means borne by the level of anti-adhesion force and torque calculations, calculated per strut length and maximum internal force, checking strut strength. Conduct of tower crane attachment means of finite element static analysis of several typical working conditions were analyzed to check the internal forces, stress and maximum displacement of each of attachment strut tower afford to give maximum force conclusions withstand the highest levels of attachment means . To ensure the effectiveness and safety of tower crane attachment means provides a theoretical reference.
