【摘要】：在礦山作業(yè)中,爆破環(huán)節(jié)是必不可少的作業(yè)工序。目前,國內(nèi)在地下采礦爆破過程中大部分采用人工或者簡易的裝藥器裝藥,都有效率低下、裝藥耦合性差、勞動強度大、安全條件差等問題。隨著越來越多的礦山開采從露天開采轉(zhuǎn)向地下開采,受到工作空間等多重限制,裝藥效果和工人安全等問題突出;所以,地下自動裝藥將取代人工方式裝藥。因此一臺運行穩(wěn)定、適用的送管裝置是地下自動裝藥所必需的。本文研究的主要內(nèi)容如下:首先,簡單介紹乳化炸藥地下現(xiàn)場混裝車發(fā)展狀況,對國內(nèi)外車用送管裝置的發(fā)展及研究現(xiàn)狀進行歸納總結。在分析總結以往設計的基礎上確定送管裝置的整體設計方案,主要包括送管方式、傳動機構,夾緊機構和檢測方案。其次,對送管裝置推送和夾持兩個重要環(huán)節(jié)進行重新設計研究。在確定采用摩擦輪式的送管裝置后,對送管輪的夾持形狀和表面防滑結構進行設計,并利用專業(yè)建模軟件SolidWorks建立裝置的三維模型。對于夾持機構將采用液控單向閥、電磁換向閥和電接點壓力表共同作用來實現(xiàn)自動控制壓力,并利用AMESim軟件對該液壓回路進行仿真,驗證能否只需要很小的擠壓量就可以達到且穩(wěn)定在所需的壓力范圍內(nèi)。最后,對送管傳動系統(tǒng)的工作原理及各組成部分進行了詳細的分析介紹,并建立了比例閥控液壓馬達速度系統(tǒng)的數(shù)學模型。對系統(tǒng)的動態(tài)響應特性進行描述,并繪制了開環(huán)系統(tǒng)的Bode圖;針對系統(tǒng)不穩(wěn)定問題,提出利用PID控制策略。與此同時,借助MATLAB/Simulink軟件建立電磁比例閥控液壓馬達系統(tǒng)的完整仿真模型。仿真結果表明,本文所采用的控制方法可以有效實現(xiàn)裝藥退管過程中速度的穩(wěn)定調(diào)控。
[Abstract]:In mine operation, blasting is an essential working procedure. At present, most of the domestic underground mining blasting process used artificial or simple charge device charge, the efficiency is low, the charge coupling is poor, the labor intensity is large. Problems such as poor safety conditions. As more and more mines move from open-pit mining to underground mining, they are subject to multiple restrictions such as workspace restrictions, and the effects of charge and worker safety are prominent; therefore, Underground automatic charge will replace manual charge. Therefore, a stable and suitable tube feeding device is necessary for underground automatic charge. The main contents of this paper are as follows: first, This paper briefly introduces the development situation of underground mixed loading vehicle of emulsion explosive, summarizes the development and research status of domestic and foreign vehicle pipe feeding device, and determines the overall design scheme of pipe feeding device on the basis of analyzing and summing up the previous design. It mainly includes pipe feeding mode, transmission mechanism, clamping mechanism and testing scheme. Secondly, two important links of pipe feeding device, push and clamp, are redesigned and studied. The clamping shape and surface anti-skid structure of the pipe feeding wheel are designed, and the 3D model of the device is established by using the professional modeling software SolidWorks. For the clamping mechanism, the hydraulic control one-way valve will be used. The electromagnetic reversing valve and the electric contact pressure gauge act together to realize the automatic control of the pressure, and use AMESim software to simulate the hydraulic circuit to verify whether it can be achieved and stabilized within the required pressure range with only a very small amount of extrusion. The working principle and components of pipe feeding drive system are analyzed and introduced in detail, and the mathematical model of proportional valve control hydraulic motor speed system is established. The dynamic response characteristics of the system are described. The Bode diagram of the open-loop system is drawn, and the PID control strategy is proposed for the instability of the system. At the same time, the complete simulation model of the electro-magnetic proportional valve controlled hydraulic motor system is established with the help of MATLAB/Simulink software. The simulation results show that, The control method adopted in this paper can effectively realize the stable control of the speed in the process of charging back tube.
