【摘要】：刮板輸送機是煤礦綜采面三機一體的重要組成部分,不但承擔(dān)著煤炭裝載、運輸?shù)闹匾蝿?wù),還為采煤機提供了運行軌道,是綜采面的重要運輸設(shè)備。刮板輸送機的安全穩(wěn)定運行關(guān)系著綜采面的正常生產(chǎn),其一旦發(fā)生故障,在查找故障點和尋找解決方案上會耗費較多的時間,直接給煤礦企業(yè)帶來經(jīng)濟損失。因此,設(shè)計刮板輸送機故障在線監(jiān)測系統(tǒng)具有重要意義,該系統(tǒng)不但可以預(yù)防刮板輸送機在使用時故障的發(fā)生,而且當(dāng)故障發(fā)生時,可以快速定位故障位置,為檢修提供方便。故障在線監(jiān)測系統(tǒng)可以實時監(jiān)測刮板輸送機的運行情況,在有故障發(fā)生時第一時間停機、發(fā)出報警,并給出相應(yīng)的故障處理方法。本課題采用傳感器、可編程控制器監(jiān)測刮板輸送機的運行狀態(tài),用RSView32上位機軟件繪制人機界面,完成了刮板輸送機的運行控制和故障在線實時監(jiān)測的設(shè)計研究。論文主要內(nèi)容包括：(1)研究刮板輸送機典型故障,利用故障樹對各組成部分的典型故障進行分類分析。(2)根據(jù)故障樹分析結(jié)果,選用不同類型傳感器對故障點進行數(shù)據(jù)采集,分析不同傳感器信號,使用PLC編制監(jiān)測程序。(3)采用上位機軟件繪制監(jiān)測畫面,對刮板輸送機的不同部位分別進行故障監(jiān)測,數(shù)據(jù)記錄和故障報警等。該系統(tǒng)增加了刮板輸送機的故障監(jiān)測點,融故障監(jiān)測和運行控制為一體,實時了解整機的運行狀態(tài),對發(fā)生的故障,及時確定故障位置,并確定解決方案,減少了刮板輸送機的維修時間,提高了煤礦企業(yè)的經(jīng)濟效益。
[Abstract]:Scraper conveyer is an important part of coal mining face, which not only undertakes the important task of coal loading and transportation, but also provides the running track for shearer, and is an important transportation equipment for fully mechanized coal face. The safe and stable operation of scraper conveyer is related to the normal production of fully mechanized coal face. Once it breaks down, it will waste more time in finding fault points and finding solutions, which will directly bring economic losses to coal mining enterprises. Therefore, it is of great significance to design the on-line fault monitoring system for scraper conveyor. This system can not only prevent the fault of scraper conveyor in use, but also quickly locate the fault position when the fault occurs, and provide convenience for maintenance. The on-line fault monitoring system can monitor the running condition of scraper conveyor in real time, stop at the first time when the fault occurs, send out alarm, and give the corresponding fault treatment method. In this paper, sensor and programmable controller are used to monitor the running state of scraper conveyor, and RSView32 software is used to draw man-machine interface. The design and research of running control and on-line real-time monitoring of scraper conveyor are completed. The main contents of this paper include: (1) study the typical fault of scraper conveyor, use fault tree to classify and analyze the typical fault of each component. (2) according to the result of fault tree analysis, select different types of sensors to collect the data of fault point. Different sensor signals are analyzed and PLC is used to compile the monitoring program. The monitoring screen is drawn up by the software of upper computer. The different parts of scraper conveyor are monitored separately, data recording and fault alarm are carried out respectively. The system adds fault monitoring points of scraper conveyer, integrates fault monitoring and operation control as an integral whole, understands the running state of the whole machine in real time, determines the fault location in time, and determines the solution for the faults that occur. The maintenance time of scraper conveyor is reduced and the economic benefit of coal mine enterprise is improved.
