【正文】 河北工程大學(xué)畢業(yè)設(shè)計(jì) I 摘 要 本論文所設(shè)計(jì)的是適用于大傾角煤層使用的單體液壓支柱。主要目的是為了保證工作人員的安全，所謂大傾角煤層就是指煤層傾角大于 25176。的煤層。其主要的改進(jìn)部位是頂蓋，由原來的通用式改為現(xiàn)在的防倒式。通過楔卡的安裝與改進(jìn)，使井下開采工作更為安全。其次，本次設(shè)計(jì)除了采用傳統(tǒng)的繪圖工具 CAD 畫圖外，還利用 Pro/E進(jìn)行三維實(shí)體造型，充分發(fā)揮出了 Pro/E 的優(yōu)點(diǎn)，使商家與使用者對該產(chǎn)品在感觀上有更進(jìn)一步認(rèn)識和了解。 關(guān)鍵詞：大傾角 頂蓋 防倒式 楔卡 三維實(shí)體造型河北工程大學(xué)畢業(yè)設(shè)計(jì) II Abstract Ascend and descend the horizontal move type stereoscopic stop the garage to is local in recent years of newly arisen property, the solution is big, inside city car parking the difficult exit consist in constructing mechanization stereoscopic stop the garage. The main purpose of designing aim as the current parking lot the problem that exits, and design a stereoscopic garage for with less place stopping putting more cars. The method depend on electrical engineering, trolley...etc. the ambulation the car regarding flat surface parking lot as the cores, and make use of the PLC to control the system to control the car the position to change into the. Consequently designed 125 hardware electric circuit for ascend and descending the stereoscopic garage of horizontal move types. Combine to proceeds to this the plait, and improved the speed. That method has the widespread meaning. Want to realize this purpose, and must choose fit of contact, pass the the point to attain to make the electrical engineering the positive and negative function that turn. The heat of fit choice avoid because of the electric current after the electric appliances over big but result in of need not want to lose, and proceeds to carry the aegis. Route of travel of fit choice switch,then attain to position the function. Introduced the every variety stereoscopic stop the garage39。s construction, control the system and its characteristics, and give out stereoscopic stop that the garage39。s main function index sign, bined to stand opposite the design important point to stop the garage to proceeds the analysised with study. Key words: Stereoscopic garage contact the electric appliances route of travel switch 河北工程大學(xué)畢業(yè)設(shè)計(jì) III 目 錄 摘要 I Abstract II 第 1 章 緒論 ........................................................................................................ 1 我國煤層賦存狀況 .................................................................................. 1 單體液壓支柱發(fā)展概況 .......................................................................... 2 國外單體液壓支柱應(yīng)用簡況 ....................................................... 2 我國單體液壓支柱的發(fā)展概況 ................................................... 2 使用單體液壓支柱的突出優(yōu)點(diǎn) ................................................... 2 機(jī)械制圖的改進(jìn) ...................................................................................... 3 軟件制圖的發(fā)展 ........................................................................... 4 Pro/E 軟件的使用簡介 ................................................................ 4 第 2 章 單體液壓支柱分類 ............................................................................ 6 分類 .......................................................................................................... 6 按用途分類 ................................................................................... 6 按升柱時(shí)工作液循環(huán)方式分類 ................................................... 6 按材質(zhì)分類 ................................................................................... 6 我國的單體液壓支柱類型 ...................................................................... 6 外注式單體液壓支柱 ................................................................... 6 內(nèi)注式單體液壓支柱 ................................................................... 7 國外單體液壓支柱類型 .......................................................................... 8 第 3 章 單體液壓支柱的結(jié)構(gòu)和工作原理 ................................................ 9 單體液壓支柱的工作原理 ...................................................................... 9 工作介質(zhì) ....................................................................................... 9 動力來源 ....................................................................................... 9 降柱方式 ....................................................................................... 9 單體液壓支柱的結(jié)構(gòu) .............................................................................. 9 單體液壓支柱三用閥、限位裝置和復(fù)位彈簧 ......................... 10 單體液壓支柱用鍛件 ................................................................. 12 活柱體與油缸 ............................................................................... 25 單體液壓支柱的橡膠件和塑料件 ........................................................ 28 河北工程大學(xué)畢業(yè)設(shè)計(jì) IV 第 4 章 單體液壓支柱結(jié)構(gòu)及尺寸的驗(yàn)算 ............................................. 30 已知設(shè)計(jì)參數(shù) ........................................................................................ 30 油缸穩(wěn)定性的驗(yàn)算 ................................................................................ 30 活塞桿的強(qiáng)度驗(yàn)算 ................................................................................ 31 缸體強(qiáng)度驗(yàn)算 ........................................................................................ 33 經(jīng)濟(jì)性分析 .......................................................................................................... 34 結(jié)論 ........................................................................................................................ 35 致謝 ........................................................................................................................ 36 參考文獻(xiàn) ................
