【摘要】：隨著我國公路事業(yè)的快速發(fā)展,大型水泥滑模攤鋪機(jī)也在不斷的得到使用和發(fā)展。然而目前大型四履帶滑模攤鋪機(jī)大部分都采用液壓傳動,而液壓傳動不僅效率低而且零部件價格昂貴使用壽命低;但使用效率高、價格相對便宜且使用壽命長的電傳動近年來卻很少被使用在大型的四履帶機(jī)械上。本文參考國內(nèi)外滑模攤鋪機(jī)的相關(guān)資料,對四履帶滑模攤鋪機(jī)整機(jī)結(jié)構(gòu)進(jìn)行了分析研究,提出了一套攤鋪機(jī)總體組成方案及工作裝置的布置方案。對攤鋪機(jī)整機(jī)機(jī)架、升降支腿的結(jié)構(gòu)以及攤鋪機(jī)的工作裝置進(jìn)行了分析,并對相關(guān)參數(shù)進(jìn)行了設(shè)計計算,確定出了一套可行的設(shè)計方案,同時根據(jù)設(shè)計數(shù)據(jù)通過三維模型軟件繪制出了主要采用電傳動的攤鋪機(jī)整體三維模型圖。通過對攤鋪機(jī)行走履帶采用液壓驅(qū)動和電驅(qū)動進(jìn)行了對比分析,確定出了行走履帶采用電驅(qū)動的具體方案,對動力傳動方式進(jìn)行了分析設(shè)計,確定出了一套可行的動力傳動方式,并對相關(guān)參數(shù)進(jìn)行計算。通過對攤鋪機(jī)使用要求的分析,制定出了一套可行的控制系統(tǒng)方案。主要對四履帶行走與轉(zhuǎn)向系統(tǒng)的控制方式進(jìn)行了分析計算,分別提出了四履帶攤鋪機(jī)在工作、轉(zhuǎn)場時行走與轉(zhuǎn)向系統(tǒng)的協(xié)調(diào)條件,并繪制了控制系統(tǒng)的程序流程圖。以觸摸屏、PLC、變頻器為主要部件,配置了整機(jī)控制系統(tǒng)的元件。通過ANSYS-Workbench軟件對行走履帶臺車架的靜力學(xué)進(jìn)行了分析,結(jié)合所選材料的特性,確定了臺車架設(shè)計的合理性和使用過程中的安全性。
[Abstract]:With the rapid development of highway industry in China, large-scale cement slipform paver has been continuously used and developed. However, at present, most of the large four-track sliding mode pavers use hydraulic transmission, which is not only inefficient but also has a low price and low service life of components; however, the use efficiency is high. Relatively cheap and long-life electric drives have been rarely used in large four-track machinery in recent years. In this paper, referring to the relevant data of the sliding form paver at home and abroad, the structure of the whole machine of the four-track sliding form paver is analyzed and studied, and a set of general composition scheme of the paver and the layout scheme of the working device are put forward. The structure of the whole machine frame, the lifting leg and the working device of the paver are analyzed, and the relevant parameters are designed and calculated, and a set of feasible design scheme is determined. At the same time, according to the design data, the whole 3D model diagram of paver, which mainly adopts electric drive, is drawn by using 3D model software. By comparing and analyzing the hydraulic driving and electric driving of the paver's walking track, the specific scheme of electric driving for the walking track is determined, and the power transmission mode is analyzed and designed. A set of feasible power transmission mode is determined and the relevant parameters are calculated. By analyzing the requirements of paver, a set of feasible control system scheme is worked out. The control mode of the four-track walking and steering system is analyzed and calculated. The coordination conditions of the four-track paver in the working and turning field are put forward, and the program flow chart of the control system is drawn. With touch screen PLC, frequency converter as the main component, the whole machine control system is configured. The statics of the track frame is analyzed by ANSYS-Workbench software, and the rationality of the frame design and the safety in the process of use are determined according to the characteristics of the selected materials.
