摘要
掘進(jìn)機(jī)是巷道掘進(jìn)和隧道施工的重要設(shè)備，它具有截割、裝載、轉(zhuǎn)運(yùn)、獨(dú)立行走、噴霧降塵等功能。但隨著現(xiàn)代化建設(shè)的不斷加快，礦山機(jī)械的迅猛發(fā)展以及對(duì)能源和建設(shè)等要求的不斷增大，掘進(jìn)機(jī)的性能還不能夠完全滿足要求，所以迫切要求設(shè)計(jì)出能夠滿足工況要求的新型掘進(jìn)機(jī)。
掘進(jìn)機(jī)的轉(zhuǎn)運(yùn)機(jī)構(gòu)是掘進(jìn)機(jī)十分重要的工作機(jī)構(gòu)，轉(zhuǎn)運(yùn)機(jī)構(gòu)運(yùn)輸能力的大小直接影響掘進(jìn)機(jī)的掘進(jìn)速度。本設(shè)計(jì)主要針對(duì)縱軸式掘進(jìn)機(jī)轉(zhuǎn)運(yùn)機(jī)構(gòu)方案設(shè)計(jì)及其技術(shù)設(shè)計(jì)。通過(guò)應(yīng)用掘進(jìn)機(jī)設(shè)計(jì)的一系列知識(shí)，對(duì)掘進(jìn)機(jī)轉(zhuǎn)運(yùn)機(jī)構(gòu)加以分析設(shè)計(jì)，運(yùn)輸系統(tǒng)采用刮板輸送機(jī)，液壓馬達(dá)驅(qū)動(dòng)，取消轉(zhuǎn)運(yùn)減速器，運(yùn)輸部根據(jù)需要選用的圓環(huán)鏈為邊雙鏈，使轉(zhuǎn)運(yùn)機(jī)構(gòu)結(jié)構(gòu)更加緊湊，運(yùn)轉(zhuǎn)更加協(xié)調(diào)，減少了故障的發(fā)生，以更好的適應(yīng)井下復(fù)雜多變的巷道情況。

Abstract
The driving machine is the important equipment of tunnel excavation and tunnel construction, which has the function of cutting, loading, transporting, walking independently, spraying dust and dust etc.. But with accelerating modernization, the rapid development of mining machinery, as well as demand for energy and construction is increasing, roadheader performance can not fully meet the requirements, there is an urgent request to design to meet the requirements of working conditions of new type roadheader.
The transport mechanism of the tunneling machine is the important working mechanism of the tunneling machine, and the transportation capacity of the transportation mechanism directly influences the driving speed of the tunneling machine.. This design is mainly to the transport mechanism of longitudinal roadheader design and technical design. Through the application of tunnel boring machine design of a series of knowledge, the transport mechanism of roadheader be analysis and design, transportation system using scraper conveyor, hydraulic motor driven, cancel the transfer speed reducer, Department of transportation according to need to use round link chain for edge double chain, transport structure is more compact, running a more coordinated, and reduce the occurrence of the fault, to better adapt to the underground complex tunnel.
Key words: Roadheader; transport mechanism design; double side chain
