摘 要
本課題是設(shè)計一個家用液壓電梯。主要思路是采用液壓動力驅(qū)動，結(jié)構(gòu)采用二級背簍形式?；钊醉敳渴且粋€定滑輪結(jié)構(gòu)，活塞缸頂起定滑輪帶動鋼絲繩，通過二級滑輪組實現(xiàn)受力和位移比例關(guān)系，從而實現(xiàn)利用較少的空間提升重物。完成背簍式家庭液壓電梯設(shè)計總體結(jié)構(gòu)設(shè)計，即完成包括總體裝配設(shè)計、主要部件設(shè)計計算、非標零件設(shè)計；升降系統(tǒng)總體的受力分析及校核計算等。
針對以上功能提出液壓電梯結(jié)構(gòu)，設(shè)計其結(jié)構(gòu)特點和工作原理，并對其零部件進行參數(shù)計算和標準化。液壓傳動系統(tǒng)可靠，電梯運行平穩(wěn)、舒適、安靜。除此之外還具有獨特的優(yōu)越性和適用性：機房位置設(shè)置靈活、安全可靠性高、承載范圍廣泛，適應(yīng)能力強、節(jié)省空間、降低成本、結(jié)構(gòu)簡潔、故障率低、易于日常維護保養(yǎng)。
本設(shè)計是為低層建筑設(shè)計的室內(nèi)小型液壓電梯，要求使用方便，有利老年人、殘障人上下樓。

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
