【摘要】：近年来随着我国经济持续高速的发展，建筑高度不断增加，建筑物外形趋于个性化，同时节能环保理念的大力提倡又使建筑外墙外保温施工日益增多，这都对用于高大异形建筑外立面施工的机械提出了更高的要求。本文依托“十一五”国家科技计划支撑项目《高大空间建筑工程安装维护设备技术与产业化开发》（项目编号：2008BAJ09B05），研发一种应用于大型建筑外墙清理、幕墙与保温材料安装的导架爬升式升降工作平台。该工作平台克服了传统的脚手架和吊篮施工的各种缺点，工作平稳、起重量大、作业面宽、安全可靠、适用性广，大大提高了劳动生产率。在对国外同类产品技术研究的基础上，结合本课题的设计要求，确定了该导架爬升式高空作业平台的主要技术参数；运用三维设计软件Solidworks完成了整机结构总体设计、主要零部件结构设计、动力和传动零部件的选型计算。通过分析危险工况下的受力情况，对支腿反力进行了理论分析，其结果与软件自动计算出的支腿反力结果进行比较，肯定了计算结果的准确性，并通过支腿反力判定整机有良好的作业稳定性。利用有限元分析软件ANSYS的静力分析模块对主要部件的强度和刚度进行了计算，对强度不满足要求的部位进行了改进设计，并利用ANSYS软件的屈曲模块对附着情况下的导架结构稳定性进行分析，确保设计在强度、刚度和稳定性方面满足要求。借助ANSYS的优化模块对支腿的截面及贴板的长度、厚度尺寸进行优化计算，使支腿在满足强度要求的前提下减轻了重量，得到更合理的设计尺寸。本文充分利用设计软件和分析软件的优势，建立了结构设计——力学分析——结构优化改进的设计流程，为产品的设计工作给出理论依据，有效的缩短了设计周期。
[Abstract]:In recent years, with the continuous and high speed development of economy in our country, the building height is increasing and the building shape tends to be individualized. Meanwhile, the promotion of the idea of energy saving and environmental protection makes the construction of exterior wall thermal insulation increasing day by day. All of these put forward higher requirements for the machinery used in the construction of the outer facade of tall special-shaped buildings. This article relies on the "11th Five-Year Plan" National Science and Technology Plan support project "Technology and industrialization Development of installation and maintenance equipment for tall Space Building Engineering" (Project No.: 2008BAJ09B05), and develops a new kind of project applied to the cleaning of exterior walls of large buildings. Curtain wall and insulation material installation of the guide climbing work platform. The work platform overcomes the shortcomings of traditional scaffolding and hanging basket construction, such as steady work, large lifting weight, wide work surface, safety and reliability, wide applicability, and greatly improves labor productivity. On the basis of the technical research of the same kind of foreign products, combined with the design requirements of this subject, the main technical parameters of the platform are determined, and the overall design of the whole machine structure is completed by using the three-dimensional design software Solidworks. Main components structural design, power and transmission parts selection calculation. Through the analysis of the force under dangerous conditions, the theoretical analysis of the reaction force of the leg is carried out. The results are compared with those calculated automatically by the software, and the accuracy of the calculation results is confirmed. And through the leg reaction to determine the whole machine has good operational stability. The static analysis module of ANSYS is used to calculate the strength and stiffness of the main components, and the design of the parts where the strength does not meet the requirements is improved. The buckling module of ANSYS software is used to analyze the stability of the guide structure under the condition of attachment to ensure that the design meets the requirements of strength, stiffness and stability. With the help of the ANSYS optimization module, the length and thickness of the supporting legs are optimized and calculated, so that the weight of the legs can be reduced and a more reasonable design size can be obtained on the premise of meeting the requirements of strength. This paper makes full use of the advantages of design software and analysis software, and establishes the design process of structural design-mechanical analysis-structure optimization improvement, which provides the theoretical basis for the design work of products and effectively shortens the design period.
