本科毕业设计说明书 分馏塔现场施工组织设计方案设计 THE DESIGN OF FRACTIONATING TOWER SITE CONSTRUCTION ORGANIZATION 学院（部）： 机械工程学院 专业班级： 学生姓名： 指导教师： 2011年 5 月 28 日 分馏塔现场施工组织设计方案设计 摘要 设备、结构吊装（统称工件），是根据工件的重量、安装部位（包括标高）和周围环境以及机索具条件等来选择吊装工艺方法。一旦吊装方法确定，则需编制吊装施工方案，对吊装过程中各部位受力进行计算，选择机索具，进行合理配置。必要时，还要对机索具进行校核。就其计算而言并不复杂，特别是在有计算机、函数计算器的今天更不困难，但需要在室内进行计算，而且要有一定文化程度的专业人员来完成。对起重工人来说就不易掌握。同时对现场临时设置吊装机索具进行计算选择也不方便。 在本设计主要是进行了吊装中的四个主要过程（抬头、脱排、腾空以及就位）的受力计算和在不同危险截面桅杆的强度和稳定性校核验算。 关键词：分馏塔，吊装，单桅杆倾斜，整体滑移法 THE DESIGN OF FRACTIONATING TOWER SITE CONSTRUCTION ORGANIZATION ABSTRACT Equipment, structure, lifting (collectively referred to as artifacts), is based on the weight of the workpiece, the installation location (including elevation) and the surrounding environment and local conditions and other rigging methods to select the lifting process. Once the method to determine the lifting, hoisting the preparation of the program is required, each part of the process of lifting the force calculation, select the machine rigging, a reasonable configuration. When necessary, but also to check on the machine rigging. In terms of its calculation is not complicated, especially in a computer, calculator, today even more difficult, but need to be calculated in the room, and to have a certain level of education professionals to complete. Crane will not be easy for workers to master. At the same time on-site lifting machine rigging temporary selection is not easy to calculate. This design is mainly carried out in a lifting of the four main processes (rise off the row, and the place vacated) the force calculation and dangerous section of the mast in different strength and stability check checking. KEYWARDS：ractionating tower, hoisting, single mast tilt, the overall sliding method 目录 摘要 i ABSTRACT ii 1绪论 1 1.1引言 1 2吊装方案的选取 1 2.1工程概况 1 2.2吊装方法及特点 2 2.3吊装方法选择的依据 2 2.4吊装方案的确定 3 3 分馏塔吊装受力计算 3 3.1吊装工艺简要说明 3 3.2吊装载荷计算 7 3.2.1抬头时刻 7 3.2.2脱排时刻 9 3.2.3设备腾空时刻 10
