摘 要
本課題是設(shè)計(jì)一個(gè)家用液壓電梯。主要思路是采用液壓動(dòng)力驅(qū)動(dòng),結(jié)構(gòu)采用二級(jí)背簍形式。活塞缸頂部是一個(gè)定滑輪結(jié)構(gòu),活塞缸頂起定滑輪帶動(dòng)鋼絲繩,通過(guò)二級(jí)滑輪組實(shí)現(xiàn)受力和位移比例關(guān)系,從而實(shí)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(jì)總體結(jié)構(gòu)設(shè)計(jì),即完成包括總體裝配設(shè)計(jì)、主要部件設(shè)計(jì)計(jì)算、非標(biāo)零件設(shè)計(jì);升降系統(tǒng)總體的受力分析及校核計(jì)算等。
針對(duì)以上功能提出液壓電梯結(jié)構(gòu),設(shè)計(jì)其結(jié)構(gòu)特點(diǎn)和工作原理,并對(duì)其零部件進(jìn)行參數(shù)計(jì)算和標(biāo)準(zhǔn)化。液壓傳動(dòng)系統(tǒng)可靠,電梯運(yùn)行平穩(wěn)、舒適、安靜。除此之外還具有獨(dú)特的優(yōu)越性和適用性:機(jī)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(qiáng)、節(jié)省空間、降低成本、結(jié)構(gòu)簡(jiǎn)潔、故障率低、易于日常維護(hù)保養(yǎng)。
本設(shè)計(jì)是為低層建筑設(shè)計(jì)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
