【摘要】：在現(xiàn)代的工業(yè)中,斗輪堆取料機是一種用于大宗散裝物料連續(xù)裝卸的高效設(shè)備,在碼頭、港口、發(fā)電廠、鋼鐵廠等散裝物料(煤炭、礦石、焦炭、砂石)存儲料場中被廣泛應(yīng)用。伴隨著科學(xué)技術(shù)不斷進步,對斗輪堆取料機控制系統(tǒng)的各項要求也愈加提高,不僅要滿足控制的準確度和安全性,同時對斗輪堆取料機操作的反應(yīng)速度、平穩(wěn)性及可靠性提出更高要求。因此,開展本文的研究內(nèi)容具有重要的工程價值和理論意義。本文以懸臂式斗輪堆取料機作為對象,首先介紹和分析了斗輪堆取料機的運行工藝及工作原理,研究了斗輪、行走、俯仰、懸臂皮帶、回轉(zhuǎn)、尾車等各個機構(gòu)的驅(qū)動方案及控制方式。然后通過PLC控制技術(shù)和變頻技術(shù)相結(jié)合的方式,來進行斗輪堆取料機控制系統(tǒng)的設(shè)計,使用SIEMENS S7-300 PLC結(jié)合SINAMICS G-120變頻器為核心構(gòu)建控制系統(tǒng)硬件平臺,應(yīng)用PLC主從雙級控制技術(shù),并在硬件平臺的基礎(chǔ)上給出控制系統(tǒng)軟件設(shè)計方案。而整個控制系統(tǒng)的網(wǎng)絡(luò)通訊方案,則通過Profibus-DP現(xiàn)場總線技術(shù)和EtherNet工業(yè)以太網(wǎng)技術(shù)來實現(xiàn)。最后使用SIMATIC MP-377觸摸屏,來構(gòu)建人機交互界面(HMI),實現(xiàn)人與機器的交流平臺;同時設(shè)計了較為完整的檢測及保護系統(tǒng)。將本文的控制方案運用在馬鞍山鋼鐵公司懸臂式斗輪機改造項目之中,結(jié)合現(xiàn)場的情況,完成了控制系統(tǒng)的硬件平臺構(gòu)建和軟件系統(tǒng)設(shè)計。構(gòu)建的控制系統(tǒng)具有穩(wěn)定可靠、使用方便、可適應(yīng)惡劣工作環(huán)境等優(yōu)點,通過變頻器調(diào)速使斗輪堆取料機獲得了更廣的調(diào)速范圍,實現(xiàn)了無極調(diào)速和等量取料,并減小電機啟動時的沖擊。使用STEP7軟件對所設(shè)計的控制系統(tǒng)進行LAD程序編寫、PLCSIM仿真,以及WINCC人機界面的組態(tài),最后對如何提高控制效果進行了研究分析,達到了提高斗輪堆取料機的生產(chǎn)作業(yè)效率,實現(xiàn)了設(shè)備的高效、穩(wěn)定運行的效果。
[Abstract]:In modern industry, bucket wheel stacker is an efficient equipment for the continuous loading and unloading of bulk materials. Bulk materials (coal, ore, coke, etc.) are loaded in wharves, ports, power plants, steel plants, etc. Sand) is widely used in storage yard. With the continuous progress of science and technology, the requirements for the control system of bucket wheel stacker are increasingly improved, not only to meet the accuracy and safety of the control, but also to respond to the operation speed of bucket wheel stacker. Stability and reliability put forward higher requirements. Therefore, the research content of this paper has important engineering value and theoretical significance. This paper takes the cantilever bucket wheel stacker as the object, firstly introduces and analyzes the operation technology and working principle of the bucket wheel stacker, and studies the bucket wheel, walking, pitching, cantilever belt, rotation, etc. The drive scheme and control mode of each mechanism such as rear car. Then, through the combination of PLC control technology and frequency conversion technology, the control system of bucket wheel stacker is designed. The hardware platform of the control system is constructed with SIEMENS S7-300 PLC and SINAMICS G-120 inverter as the core, and the PLC master-slave two-stage control technology is applied. On the basis of the hardware platform, the software design of the control system is given. The network communication scheme of the whole control system is realized by Profibus-DP fieldbus technology and EtherNet industrial Ethernet technology. Finally, the SIMATIC MP-377 touch screen is used to construct the man-machine interaction interface to realize the communication platform between human and machine, and a relatively complete detection and protection system is designed at the same time. The control scheme of this paper is applied to the renovation project of the cantilever bucket wheel machine in Ma'anshan Iron and Steel Company, and the hardware platform and the software system design of the control system are completed in combination with the situation in the field. The control system is stable and reliable, easy to use, and can adapt to the bad working environment. Through the speed regulation of frequency converter, the bucket wheel stacker can obtain a wider range of speed regulation, and realize the stepless speed regulation and the same amount of material. And reduce the impact when the motor starts. The STEP7 software is used to compile the LAD program of the designed control system and the configuration of the WINCC man-machine interface. At last, how to improve the control effect is studied and analyzed, and the production efficiency of the bucket wheel stacker is improved. The effect of high efficiency and stable operation of the equipment is realized.
