【正文】 定設(shè)計(jì)。最后由整體性能去確定 PLC 控制系 統(tǒng)的設(shè)計(jì),根據(jù)已有的情況去設(shè)計(jì)控制方案,在已經(jīng)確定方案的情況下去對(duì)控制系統(tǒng)的硬件進(jìn)行設(shè)計(jì)如主電路設(shè)計(jì)與 PLC 型號(hào)的確定。然后進(jìn)行 PLC控制程序的開(kāi)發(fā)與設(shè)計(jì)。最后我們需要對(duì)整體的設(shè)計(jì)進(jìn)行理論上的分析與驗(yàn)證。在所有設(shè)計(jì)均完成后我們要進(jìn)行仿真實(shí)驗(yàn)以及液壓試驗(yàn)臺(tái)上的驗(yàn)證實(shí)驗(yàn)。 關(guān)鍵詞 : 工況分析;液壓系統(tǒng)設(shè)計(jì); PLC控制系統(tǒng)設(shè)計(jì) Abstract With the development of the society and the continuous improvement of human production, more and more of the mechanical equipment is applied to production field. Make mechanical equipment gradually into the public view, it is well known in the great age of knowledge explosion, the petition between countries and in the final analysis is the petition of productivity, the productivity is the core of today39。s petition. The development of productive forces decided to every enterprise and even the fate of the country. Along with the progress of science and technology, more and more scientific knowledge have been applied to production practice, the hydraulic system because of its inparable superiority also gradually being used in many fields. Due to its stable and reliable hydraulic system and other factors, such as big power in the daily production of mechanical equipment in the swift and violent development. Production efficiency is an important index to the survival of an enterprise, the development of an enterprise and its production efficiency is inseparable, many thanks to the development of industrialization of moving equipment use into industries instead of traditional artificial manual labor. PLC system with its strong maneuverability simple easy to use, safe and reliable gradually into the many emerging areas, so the bination of hydraulic system and PLC control system used in the field of engineering machinery. On the graduation design topic is about the keep up with the pace of social productivity. Subject to full hydraulic drilling rig hydraulic system design and PLC control, mainly embodies the PLC control theory application in mechanical production. The design task of driving system has a unified control hydraulic system, hydraulic system differences directly affect the success or failure of the final design, while the control system with PLC system for full operation, the part directly determines its market in the field of production, productivity in the field of automation. Its basic design parameters is: the drill pipe to push schedule for 600 mm, maximum thrust 30 KN, the pulling force of 60 largest KN, return to drill for: speed of 10100 r/min, the maximum torque of 2021Nm. Hydraulic system design and choice of fully hydraulic drill PLC control quantity of cloth is divided into design objects. This topic mainly is to use the PLC control 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。 The design of the hydraulic system。 PLC control system design.沈陽(yáng)化工大學(xué)科亞學(xué)院學(xué)士學(xué)位論文第一章 引言 1 第一章 引言 問(wèn)題分析及其對(duì)策 國(guó)家制造業(yè)的發(fā)展?fàn)顩r 在現(xiàn)在工業(yè)的發(fā)展過(guò)程中,機(jī)械的加工方式越來(lái)越多,一個(gè)好的加工方式也許可以改變一種格局。而我們國(guó)家由于工業(yè)化進(jìn)程不是特別完善,目前還處于大力發(fā)展的階段。許多自動(dòng)化設(shè)備需要在日常生產(chǎn)中得到應(yīng)用。 提出問(wèn)題 在機(jī) 械行業(yè)的加工中安全是重中之重的話題,而效率是企業(yè)賴以生存及發(fā)展的命門(mén)所在,而這兩個(gè)方面在某些情況下看起來(lái)是矛盾的傳統(tǒng)的鉆機(jī)存在以下幾點(diǎn)不足: ,故自動(dòng)化程度不高,在生產(chǎn)中難以進(jìn)行大批量的生產(chǎn); ,設(shè)備的效率不高; 3自動(dòng)化程度不高,占用大量的人工。 分析相關(guān)的問(wèn)題及制定解決方案 在以往我們的鉆機(jī)的自動(dòng)化程度不高,效率不高,體積大系統(tǒng)的抗干擾能力差。而且操作比較繁瑣,增大了工人的工作量。所以在以后的社發(fā)展進(jìn)程中機(jī)械相關(guān)設(shè)備與液壓系統(tǒng)及 PLC 控制系統(tǒng)相結(jié) 合的方向會(huì)越來(lái)越多。 我們主要對(duì)鉆機(jī)的液壓傳動(dòng)系統(tǒng)以及控制系統(tǒng)的改進(jìn),去解決上面所提到的問(wèn)題。通過(guò)使用先進(jìn)的傳動(dòng)系統(tǒng)來(lái)節(jié)約動(dòng)力。引進(jìn)先進(jìn)的控制系統(tǒng)去實(shí)現(xiàn)系統(tǒng)的自動(dòng)化操作。下面對(duì)各部分提出改正方案: ( 1)傳動(dòng)系統(tǒng) 為了便于改進(jìn)日后的加工操作以及日常的工作要求,在完成整體的設(shè)計(jì)計(jì)算后對(duì)該傳動(dòng)系統(tǒng)進(jìn)行整改和調(diào)整。 ( 2)控制系統(tǒng) PLC 控制系統(tǒng)可靠性能高,抗干擾能力強(qiáng),維修簡(jiǎn)單操作性沈陽(yáng)化工大學(xué)科亞學(xué)院學(xué)士學(xué)位論文第一章 引言 2 強(qiáng)便于學(xué)習(xí)與應(yīng)用而且價(jià)格低,使用方便,擴(kuò)充靈活功能也非常完善。所以我們使用 PLC 控制系統(tǒng)對(duì)液壓鉆機(jī)進(jìn)行控制。 本課題主要設(shè) 計(jì)內(nèi)容與目標(biāo) 我們通過(guò)對(duì)傳統(tǒng)鉆機(jī)的改進(jìn),重點(diǎn)是對(duì)傳動(dòng)系統(tǒng)與控制系統(tǒng)的設(shè)計(jì)。通過(guò)我們這個(gè)課題的設(shè)計(jì)克服鉆機(jī)原來(lái)所具有的部分不足使其性能得以提高,并實(shí)現(xiàn)機(jī)械生產(chǎn)中的自動(dòng)化。我們?cè)O(shè)計(jì)完成后需要滿足以下要求: 1. 實(shí)現(xiàn)自動(dòng)化可以連續(xù)的應(yīng)用與工業(yè)生產(chǎn),提高加工效率,改善產(chǎn)品加工質(zhì)量 。 2. 可以減少工作人員的工作量; 3. 設(shè)備適應(yīng)性強(qiáng),可以滿足設(shè)計(jì)要求; 4. 經(jīng)濟(jì)成本低。沈陽(yáng)化工大學(xué)科亞學(xué)院學(xué)士學(xué)位論文第二章 全液壓鉆機(jī)的工作原理與基本構(gòu)成 3 第二章 全液壓鉆機(jī)的工作原理與基本構(gòu)成 全液壓鉆機(jī)自身的基本組成 首先從應(yīng)該從系統(tǒng)仿真建模的方面,工 程鉆機(jī)分為四個(gè)主要部分:操作、機(jī)械、液壓、動(dòng)力這幾個(gè)系統(tǒng)構(gòu)成。它是一個(gè)整體,整體性能與各部分息息相關(guān)分。 以為鉆機(jī)本身的使用環(huán)境在室內(nèi),環(huán)境溫度的變化大,容易受到污染,所以使用柴油機(jī)。它檢修方便、使用性能可靠、成本低,滿足工程鉆機(jī)特點(diǎn) 。 它主要?jiǎng)幼饔谢剞D(zhuǎn)器的回轉(zhuǎn)、鉆具的給進(jìn)、鉆具的夾緊等,所有的機(jī)器運(yùn)動(dòng)都靠液壓傳動(dòng)來(lái)完成。由以上的要求,把它們連接在一起就構(gòu)成工程鉆機(jī)自己的液壓系統(tǒng)。柴油機(jī)是通過(guò)泵把機(jī)械能使液壓油為媒介,轉(zhuǎn)化為液壓能,傳遞給馬達(dá)和給進(jìn)油缸,從而實(shí)現(xiàn)整個(gè)過(guò)程。 該鉆機(jī)依據(jù)鉆進(jìn)的動(dòng)作要求和工藝特點(diǎn)采用雙泵系統(tǒng),使用恒壓變量泵和負(fù)載敏感泵各一個(gè)。 鉆機(jī)本身的機(jī)械系統(tǒng)是做完鉆機(jī)各個(gè)規(guī)定動(dòng)作的首要執(zhí)行者,大概包括: 履帶行走裝置: 整個(gè)鉆機(jī)的支撐部分及基體,承擔(dān)整個(gè)鉆機(jī)的全部質(zhì)量及鉆進(jìn)過(guò)程中造成外載荷的反作用力,而且可以完成短距離的行走運(yùn)動(dòng),搬遷簡(jiǎn)單,節(jié)約作業(yè)輔助的時(shí)間。 回轉(zhuǎn)裝置:在機(jī)器某個(gè)工作位置,讓機(jī)身環(huán)繞中央回轉(zhuǎn)軸旋轉(zhuǎn)某個(gè)角度,從而使整機(jī)在不用移動(dòng)的情況下就可以完成多角度施工 。 工作裝置:它是鉆機(jī)形成鉆進(jìn)運(yùn)動(dòng)的主要構(gòu)成部分,常用的有回轉(zhuǎn)器、機(jī) 身、卸扣器、夾持器等。整個(gè)鉆機(jī)的核心是工作裝置, 它是鉆機(jī)的執(zhí)行機(jī)構(gòu)。當(dāng)鉆機(jī)做鉆進(jìn)時(shí),工作裝置使得鉆桿給進(jìn)及旋轉(zhuǎn);當(dāng)鉆具起下時(shí),除要驅(qū)動(dòng)鉆桿后退沈陽(yáng)化工大學(xué)科亞學(xué)院學(xué)士學(xué)位論文第二章 全液壓鉆機(jī)的工作原理與基本構(gòu)成 4 和前進(jìn)外,還應(yīng)該實(shí)現(xiàn)機(jī)械可以擰卸鉆桿。 該的操縱裝置是系統(tǒng)對(duì)執(zhí)行元件控制、換向閥等機(jī)構(gòu)的操作裝置,通過(guò)管路連接將所有的執(zhí)行元件集中于一個(gè)操作平臺(tái)上,通過(guò)使用液壓手柄實(shí)現(xiàn)對(duì)鉆機(jī)的各種工作過(guò)程的控制。 全液壓鉆機(jī)的工作原理 全液壓鉆機(jī)通過(guò)以鉆頭進(jìn)行鉆進(jìn)工作的機(jī)械,各個(gè)部分的運(yùn)動(dòng)是通過(guò)液壓缸本身伸縮來(lái)完成。變幅裝置是由調(diào)角連接板
