摘要户外升降机又称为建筑用施工电梯,是建筑施工中经常使用的载货和载人的 运输机械施工升降机主要由导轨架附墙架吊笼和安全机构组成。随着我国经济社 会的发展,高层超高层建筑不断涌现,施工升降机的需求量大增,同时对施工升 降机的安全性也提出了更高的要求导轨架是施工升降机的重要组成部分,其强度 特性对施工升降机的整体安全性具有极其重要的影响相比静态应力,施工升降机 运行过程中由动载荷引起的动态应力更容易造成施工升降机结构的破坏,因此有 必要对施工升降机进行静力学分析。81986
本课题所设计的一种施工升降机时在现有的施工升降机的基础上通过改进 和分析设计出来的一种链式导轨型轻型施工升降机,并对其进行了详细零部件的 设计和有限元校核。
本次设计的主要零部件有承重吊笼、底座、导轨等。采用有限元分析软件 ABAQUS 对其在工程应用中的的变形及应力情况。并用三维软件 ProE 进行建模。 再把模型导入到 ABAQUS 中进行有限元分析。最后利用有限元分析的结果对升降 机的性能进行评价。

Abstract Outdoor construction elevator up and down to play in the delivery of our role in engineering practice, is used to transport people and goods, even though many years have passed development and progress, but there are still a lot of structure and properties of the problem is not resolved, for structural design and improve the delivery of reference。 The paper described the main contents are as follows:
Using the three-dimensional design software SolidWorks and Proe establish a complete outdoor lift model。 It includes L-shaped bearing plate, guide rails, a base, a drive system and the like。 By learning and understanding of access to information throughout the lift works。
Adoption of the working conditions, manufacturing processes, speed and lifting power requirements, to determine the specific dimensions and materials of the pulley。 Bearing capacity calculated by rail to design wind load body size and material selection guide。 By the calculation of the L-shaped bearing plate gravity design chosen its body size and material。
By calculating wind load, impact load, limit load condition and moment, L-shaped design of the bearing plate and the base of the ideal assembly dimensions。
Use the built model and the calculated force module FEM strength analysis and optimization, including the L-shaped bearing plate and the base。
Key word: outdoor elevator, ,strength check, finite element analysis
