摘 要
本設(shè)計(jì)首先對(duì)液壓防爆提升機(jī)的用途、工作原理、類型及其發(fā)展歷程進(jìn)行了概述，通過對(duì)液壓傳動(dòng)優(yōu)缺點(diǎn)的分析以及與其它類型提升機(jī)進(jìn)行比較確定了液壓系統(tǒng)的設(shè)計(jì)方案。然后通過對(duì)其工作環(huán)境和技術(shù)特點(diǎn)的分析，并參考目前國內(nèi)液壓防爆提升機(jī)的結(jié)構(gòu)，對(duì)液壓防爆提升機(jī)的整體結(jié)構(gòu)進(jìn)行了設(shè)計(jì)，包括鋼絲繩的選擇、卷筒的設(shè)計(jì)、主軸裝置的設(shè)計(jì)、制動(dòng)裝置的設(shè)計(jì)、液壓系統(tǒng)的設(shè)計(jì)以及計(jì)算與校核。本設(shè)計(jì)由防爆電動(dòng)機(jī)、低速大扭矩液壓馬達(dá)、軸向柱塞泵、雙聯(lián)葉片泵、多種控制閥、盤形制動(dòng)器、卷筒、支承軸等部件組成。由于液壓系統(tǒng)部分比較復(fù)雜，為了使提升機(jī)的結(jié)構(gòu)緊湊，提高液壓系統(tǒng)的性能和指標(biāo)，將其主回路部分和其它部分分別組合在一起，構(gòu)成主閥組和控制閥組。此液壓提升機(jī)的特點(diǎn)是：采用液壓傳動(dòng)、采用無級(jí)調(diào)速、結(jié)構(gòu)緊湊、操縱簡(jiǎn)單、采用液壓控制、制動(dòng)安全可靠，其最大的優(yōu)點(diǎn)是防爆功能。本液壓提升機(jī)用于礦山、港口、碼頭等需要搬運(yùn)物料的場(chǎng)所，尤其在煤礦井下等含有瓦斯或其它易燃易爆氣體的場(chǎng)所廣泛應(yīng)用。

Abstract
The first design of the hydraulic hoist the use of explosion-proof, principle, type and its development process was outlined by the advantages and disadvantages of hydraulic and other types of analysis and comparison determine elevator hydraulic systems design. Then through their work environment and the technical characteristics of the analysis, and refer to the current domestic hydraulic elevator explosion-proof structure of the hydraulic elevator explosion-proof structure of the overall design, including the choice of wire rope, roll the design, spindle Equipment design, the design of the braking system, hydraulic system design and calculation and verification. The design by the explosion-proof motor, a low-speed torque hydraulic motors, axial piston pump, double-blade pump, a variety of control valves, disc brakes, drum, the support shaft and other components。As part of the hydraulic system more complicated, in order to hoist the compact structure, improve the performance of the hydraulic system and indicators, its main circuit and other parts of the portfolio together, constitute the main valve block and control valve block. This hydraulic hoist features: The hydraulic transmission, a stepless speed regulation, compact and simple manipulation, the use of hydraulic control, brake safe and reliable, its biggest advantages is the explosion-proof function. The hydraulic hoist used for mining, ports, terminals and other necessary materials handling establishments, particularly in the coal mine gas, such as containing flammable and explosive gases or other places widely used.
