【摘要】：煤炭作為傳統(tǒng)能源在當(dāng)今社會(huì)發(fā)展中仍然發(fā)揮著不可或缺的作用，隨著科技的發(fā)展，煤炭開采設(shè)備的自動(dòng)化程度越來越高。電牽引采煤機(jī)是綜采工作面的核心設(shè)備，整機(jī)重量較大、結(jié)構(gòu)復(fù)雜，面對(duì)生產(chǎn)率不斷提高的要求，其有效運(yùn)行時(shí)間直接影響工作面的產(chǎn)能。 電牽引采煤機(jī)工作環(huán)境異常復(fù)雜、惡劣，其行走機(jī)構(gòu)的穩(wěn)定性和結(jié)構(gòu)強(qiáng)度對(duì)電牽引采煤機(jī)的正常運(yùn)行有著至關(guān)重要的作用。本文主要以電牽引采煤機(jī)行走機(jī)構(gòu)為研究對(duì)象，以TRIZ理論為理論基礎(chǔ)，結(jié)合機(jī)械力學(xué)對(duì)電牽引采煤機(jī)進(jìn)行力學(xué)特性分析，深入了解行走機(jī)構(gòu)的齒軌輪、導(dǎo)向滑靴和銷排在實(shí)際工況下的受力規(guī)律及其故障原因。 通過對(duì)電牽引采煤機(jī)行走機(jī)構(gòu)所涉及的工程問題分析，用通用工程參數(shù)對(duì)問題進(jìn)行描述，將其轉(zhuǎn)化為一般問題。運(yùn)用阿奇舒勒矛盾矩陣對(duì)實(shí)際工程問題進(jìn)行矛盾分析，找到矛盾的根本原因，并利用推薦的創(chuàng)新原理逐一解決矛盾，最終給出解決問題的通用方案集。結(jié)合行走機(jī)構(gòu)實(shí)際工程問題，將通用方案集轉(zhuǎn)化為針對(duì)行走機(jī)構(gòu)的具體創(chuàng)新設(shè)計(jì)方案集。建立模糊評(píng)價(jià)體系對(duì)行走機(jī)構(gòu)各創(chuàng)新設(shè)計(jì)方案進(jìn)行模糊綜合評(píng)價(jià)，確定最佳創(chuàng)新設(shè)計(jì)方案，并進(jìn)行合理性分析。 將TRIZ理論與模糊評(píng)價(jià)理論相結(jié)合，運(yùn)用到電牽引采煤機(jī)行走機(jī)構(gòu)的工程問題中來，，可找到解決問題的最佳方法，確定最佳創(chuàng)新設(shè)計(jì)方案。電牽引采煤機(jī)行走機(jī)構(gòu)的工程問題解決將大幅提高其工作可靠性，保證綜采工作面的產(chǎn)能。
[Abstract]:Coal, as a traditional energy, still plays an indispensable role in the development of society. With the development of science and technology, the automation of coal mining equipment is more and more high. Because of its large weight and complicated structure, the effective running time of the whole machine directly affects the productivity of the working face in the face of increasing productivity. The working environment of electric traction shearer is extremely complex and bad. The stability and structural strength of its walking mechanism play an important role in the normal operation of electric traction shearer. On the basis of TRIZ theory, the mechanical characteristics of electric haulage shearer are analyzed in combination with mechanical mechanics, and the force law of gear rail wheel, guide slipper and pin row of walking mechanism under actual working conditions and the causes of failure are deeply understood. Through the analysis of the engineering problems involved in the walking mechanism of electric haulage shearer, the problems are described with general engineering parameters and converted into general problems, and the actual engineering problems are analyzed by using the Acheshule contradiction matrix. Find out the root cause of the contradiction, and use the recommended innovation principle to solve the contradiction one by one, and finally give a general solution to the problem set, combined with the actual engineering problems of walking mechanism, The general scheme set is transformed into the specific innovative design scheme set for the walking mechanism, and the fuzzy evaluation system is established to evaluate the various innovative design schemes of the walking mechanism, to determine the best innovative design scheme, and to analyze the rationality of the fuzzy evaluation system. By combining TRIZ theory with fuzzy evaluation theory and applying it to the engineering problem of electric haulage shearer walking mechanism, the best method to solve the problem can be found. The optimal innovative design scheme is determined. The engineering problem solving of the walking mechanism of electric haulage shearer will greatly improve its working reliability and ensure the production capacity of fully mechanized coal mining face.
