家用液压电梯毕业论文正文.doc

摘 要 本课题是设计一个家用液压电梯。主要思路是采用液压动力驱动，结构采用二级背篓形式。活塞缸顶部是一个定滑轮结构，活塞缸顶起定滑轮带动钢丝绳，通过二级滑轮组实现受力和位移比例关系，从而实现利用较少的空间提升重物。完成背篓式家庭使用方便，有利老年人、残障人上下楼Abstract This subject was designed as a household hydraulic elevator. Main idea was created by hydraulic system. Structure was adopt two-level basket form. piston-cylinder is a fixed pulley at the top of the structure，the piston-cylinder drive pulley set from the top rope to raise heavy objects. Through the two-level belts and pulleys to make the power and distance expand. So that use less space to rise heavy substance. Complete including general assembly design, main components design calculation, non-standard parts design； The lifting system overall analysis of stress and check calculation. Hydraulic lift for the proposed structure of the above features，design features and working principle of their structure and parameters of its components calculated and standardized. Hydraulic lift has the reliable hydraulic drive system，the quiet and smooth. Compared with traction type lift hydraulic lift has the following outstanding advantage：the flexible setting of the machine room position；the highest safe and reliable properties；the wide bearing range and the stronger adaptability；it saves the space，reduces energy consumption and cuts down the cost；hydraulic lift is of the concise structure，low trouble rate. It is easy for the daily maintenance. This hydraulic elevator is designed for low-rise buildings of indoor small，it demand easy to use，and it can helps old people and some disable people to move. Keywords: Elevator Structural Design Hydraulic System Hulleys 目 录 摘 要 I Abstract II 引 言 1 1. 概 述 2 1.1 项目要求 2 1.2 项目意义 2 1.3 国内外现状 3 1.3.1 国内 3 1.3.2 国外 3 1.3.3 展望 5 1.4 液压电梯的技术特点与控制类型 5 1.4.1 技术特点 5 1.4.2 控制类型 6 2. 设计方案论证 8 2.1 剪叉液压电梯 8 2.1.1 结构特点 8 2.1.2 工作原理 8 2.2 直升式液压电梯 9 2.2.1结构特点 9 2.2.2工作原理 9 2.3 背篓式液压电梯 10 2.3.1结构特点 10 2.3.2工作原理 11 2.4 结论及选定方案 11 2.4.1 选定方案 12 2.4.2 电梯总体布局 12 3. 设计计算 14 3.1 布局解析 14 3.2 受力分析 15 3.2.1上升下降
