The Design And Research For Key Structure Of Mast Climbing Aerial Work Platform

With the rapid development of economic construction provide a broad market, the emergence of a variety of tall buildings in a city, the work high above the safety and quality problems become a problem that nots allow to ignore. Especially this year, the construction safety accident frequency, to the construction enterprise is a wake-up call. Research and development, therefore, safe and reliable, high work efficiency of construction machinery to solve all kinds of complicated conditions encountered in aerial work has important engineering value.In order to more efficient foreign metope irregular building exterior wall operations, such as exterior wall thermal insulation engineering, exterior wall paint job, reduce the labor cost of erection of traditional scaffolding, and can improve the efficiency of aerial work, this topic design a applied to large building external wall cleaning, curtain wall with thermal insulation material installation guide frame pole climbing elevating work platform. The work platform combines the advantages of traditional scaffolding and hanging basket construction, wide working smoothly, big lifting weight, operation, safe and reliable, wide applicability, has greatly raised Labour productivity, in high-rise building construction has a broad market prospect.Firstly,systematic analysis of the three kinds of the construction of the main way, compares their advantages and disadvantages, puts forward the guide tube creeper platform design research. Through market research of existing products at home and abroad and based on the analysis of the function, determine the guide frame pole climbing the overall structure of the work platform. The overall structure model is established. The function of the platform were analyzed, the main technical parameters, and the structure design and selection of main componentsUsing the finite element analysis software ANSYS static analysis module of the main components of the strength and stiffness are calculated, the strength does not meet the requirements of parts was improved design. Using ANS YS optimization module of the leg section length, thickness, size of the strap and optimization calculation, and make the leg under the premise of meeting the strength requirement to lose weight, get a more reasonable design size.Do some studies on the stability of the whole machine, analysis the stress of the dangerous working conditions, buckling module of ANSYS software to free the working status and attached guide under the circumstance of structural stability is analyzed, to ensure that the design meet the requirements in terms of strength, stiffness and stability.
