【摘要】：近年來(lái)隨著我國(guó)經(jīng)濟(jì)持續(xù)高速的發(fā)展，建筑高度不斷增加，建筑物外形趨于個(gè)性化，同時(shí)節(jié)能環(huán)保理念的大力提倡又使建筑外墻外保溫施工日益增多，這都對(duì)用于高大異形建筑外立面施工的機(jī)械提出了更高的要求。本文依托“十一五”國(guó)家科技計(jì)劃支撐項(xiàng)目《高大空間建筑工程安裝維護(hù)設(shè)備技術(shù)與產(chǎn)業(yè)化開發(fā)》（項(xiàng)目編號(hào)：2008BAJ09B05），研發(fā)一種應(yīng)用于大型建筑外墻清理、幕墻與保溫材料安裝的導(dǎo)架爬升式升降工作平臺(tái)。該工作平臺(tái)克服了傳統(tǒng)的腳手架和吊籃施工的各種缺點(diǎn)，工作平穩(wěn)、起重量大、作業(yè)面寬、安全可靠、適用性廣，大大提高了勞動(dòng)生產(chǎn)率。 在對(duì)國(guó)外同類產(chǎn)品技術(shù)研究的基礎(chǔ)上，結(jié)合本課題的設(shè)計(jì)要求，確定了該導(dǎo)架爬升式高空作業(yè)平臺(tái)的主要技術(shù)參數(shù)；運(yùn)用三維設(shè)計(jì)軟件Solidworks完成了整機(jī)結(jié)構(gòu)總體設(shè)計(jì)、主要零部件結(jié)構(gòu)設(shè)計(jì)、動(dòng)力和傳動(dòng)零部件的選型計(jì)算。 通過分析危險(xiǎn)工況下的受力情況，對(duì)支腿反力進(jìn)行了理論分析，其結(jié)果與軟件自動(dòng)計(jì)算出的支腿反力結(jié)果進(jìn)行比較，肯定了計(jì)算結(jié)果的準(zhǔn)確性，并通過支腿反力判定整機(jī)有良好的作業(yè)穩(wěn)定性。 利用有限元分析軟件ANSYS的靜力分析模塊對(duì)主要部件的強(qiáng)度和剛度進(jìn)行了計(jì)算，對(duì)強(qiáng)度不滿足要求的部位進(jìn)行了改進(jìn)設(shè)計(jì)，并利用ANSYS軟件的屈曲模塊對(duì)附著情況下的導(dǎo)架結(jié)構(gòu)穩(wěn)定性進(jìn)行分析，確保設(shè)計(jì)在強(qiáng)度、剛度和穩(wěn)定性方面滿足要求。 借助ANSYS的優(yōu)化模塊對(duì)支腿的截面及貼板的長(zhǎng)度、厚度尺寸進(jìn)行優(yōu)化計(jì)算，使支腿在滿足強(qiáng)度要求的前提下減輕了重量，得到更合理的設(shè)計(jì)尺寸。 本文充分利用設(shè)計(jì)軟件和分析軟件的優(yōu)勢(shì)，建立了結(jié)構(gòu)設(shè)計(jì)——力學(xué)分析——結(jié)構(gòu)優(yōu)化改進(jìn)的設(shè)計(jì)流程，為產(chǎn)品的設(shè)計(jì)工作給出理論依據(jù)，有效的縮短了設(shè)計(jì)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.
