【正文】 trol system of hydraulic drive knowledge and knowledge, reflect the mechanical and hydraulic knowledge, and the bination of electrical control. In need to plete the following: in the design of hydraulic schematic diagram design, job requirement analysis, analysis of working condition, the determination of process parameters, the structure and principles of fully hydraulic drill, the selection of hydraulic ponents, the performance of calculus, dynamic simulation, the choice of control scheme, the performance of type selection of PLC, ladder diagram design, PLC hardware circuit design and simulation and verification in the hydraulic testbed. Conclusion from the above points you need to first the basic working principle of hydraulic drilling rig and its basic position have a basic understanding of, when the design should fully consider the work of the actual situation. Secondly to analyze the working condition of each institution and loading conditions. And then the next step for us laying a foundation for the analysis and design of the hydraulic system provides theory basis. According to the analysis of the front to consider the choice of hydraulic ponents. Key words: operating mode analysis。然后進(jìn)行 PLC控制程序的開發(fā)與設(shè)計。其次要分析每個機(jī)構(gòu)的工作狀況及受載情 況。選擇全液壓鉆機(jī)的液壓系統(tǒng)設(shè)計與 PLC 控制量 布分為設(shè)計對象。 此次進(jìn)行的畢業(yè)設(shè)計課題正是 關(guān)于這個方面的緊跟社會生產(chǎn)力的步伐。伴隨科學(xué)技術(shù)的進(jìn)步越來越多的科學(xué)知識被不斷運用到生產(chǎn)實踐當(dāng)中，液壓系統(tǒng)由于其無與倫比的優(yōu)越性也漸漸被用在眾多領(lǐng)域。 致謝 ....................................................................... 錯誤 !未定義書簽。 液壓鉆機(jī) PLC 的程序運行 ........................ 錯誤 !未定義書簽。 目 錄 第一章 引言 ................................................................................... 1 問題分析及其對策 ....................................................................... 1 國家制造業(yè)的 發(fā)展?fàn)顩r .......................................................... 1 提出問題 ................................................................................. 1 分析相關(guān)的問題及制定解決方案 .......................................... 1 本課題主要設(shè)計內(nèi)容與目標(biāo) ...................................................... 2 第二章 全液壓鉆機(jī)的工作原理與基本構(gòu)成 .................................... 3 全液壓鉆機(jī)自身的基本組成 ...................................................... 3 全液壓鉆機(jī)的工作原理 .............................................................. 4 第三章 設(shè)計要求及工況分析 ........................................................... 5 任務(wù)及要求 ................................................................................. 5 原始參數(shù)值 ................................................................................. 5 第四章 擬定液壓系統(tǒng)原理圖 ........................................................... 6 確定液壓執(zhí)行元件的類型 .......................................................... 6 運動和負(fù)載分析 ..................................................................... 6 液壓缸的選定 ......................................................................... 7 選擇液壓基本回路 ...................................................................... 8 調(diào)壓回路 ................................................................................. 8 調(diào)速回路 ................................................................................. 8 支承油缸鎖緊回路 ................................................................. 8 行走系統(tǒng) ................................................................................. 8 液壓回路的合成 .......................................................................... 9 第五章 液壓系統(tǒng)性能參數(shù)的確定 ................................................... 11 液壓泵的選用 ............................................................................. 11 電動機(jī)的選用 ............................................................................. 11 液壓閥的選用 ............................................................................. 12 單向閥的選擇 ......................................................................... 12 換向閥的選用 ......................................................................... 13 壓力閥的選擇 ......................................................................... 13 流量控制閥的選用 ................................................................. 14 壓力表開關(guān)的選擇 ....................................................................... 14 液壓油的選擇 ............................................................................. 14 聯(lián)軸器的選擇 ............................................................................. 15 油箱的設(shè)計 ................................................................................. 16 油箱的大致外形尺寸及有效容積的確定 ............................... 16 濾油器的選擇 ......................................................................... 17 空氣濾清器的選擇 ................................................................. 18 液位計的選擇 ......................................................................... 18 確定油箱各板尺寸和附件安裝位置 ...................................... 19 設(shè)計液壓機(jī)的油管 ...................................................................... 24 設(shè)計確定鋼管的管徑 .............................................................. 24 膠 管的選擇 ................................................................................. 25 第六章 液壓系統(tǒng)性能的驗算 ........................................................... 27 液壓系統(tǒng)的壓力驗算 .................................................................. 27 系統(tǒng)的溫升驗算 .......................................................................... 27 液壓系統(tǒng)的效率的檢查 .............................................................. 28 第七章 液壓鉆機(jī)的 PLC 控制系統(tǒng)的設(shè)計 ...................................... 30 PLC 的特點及應(yīng)用 ...................................................................... 30 全液壓鉆機(jī)的 PLC 控制系統(tǒng)的方案設(shè)計 .................................. 30 液壓鉆機(jī)的控制電路與 PLC 型號選定 ...................................... 31 液壓鉆機(jī)的控制電路設(shè)計 ....................................................... 31 PLC 型號選定 ............................................. 錯誤 !未定義書簽。 液壓鉆機(jī) PLC 的運行程序、調(diào)試及監(jiān)控 ..... 錯誤 !未定義書簽。
