摘要
刮板輸送機(jī)是綜采工作面配套設(shè)備的重要組成部分,是煤炭裝運(yùn)的第一個(gè)環(huán)節(jié)。因此，刮板輸送機(jī)的輸送能力在很大程度上決定了采煤工作面的生產(chǎn)能力和效率。然而，我國(guó)生產(chǎn)技術(shù)落后，目前設(shè)計(jì)生產(chǎn)的刮板輸送機(jī)裝機(jī)功率小,輸送能力低,運(yùn)輸距離短，耐久性差,可靠性低，壽命短。綜合分析我國(guó)刮板輸送機(jī)的使用現(xiàn)狀，設(shè)計(jì)制造高性能的刮板輸送機(jī)迫在眉睫。本文首先綜合比較了各種類型輸送機(jī)的特點(diǎn)，根據(jù)實(shí)際情況選用了中單鏈型刮板輸送機(jī)。而后，對(duì)中單鏈型刮板輸送機(jī)進(jìn)行了總體結(jié)構(gòu)設(shè)計(jì)。對(duì)機(jī)頭傳動(dòng)裝置、過渡槽、中部槽、刮板鏈、刮板、鏈輪、機(jī)尾等主要部件進(jìn)行了技術(shù)分析和結(jié)構(gòu)設(shè)計(jì)，完成了中單鏈型刮板輸送機(jī)的整體設(shè)計(jì)。此次設(shè)計(jì)的中單鏈型刮板輸送機(jī)左右兩側(cè)對(duì)稱，可以在兩側(cè)壁上安裝減速器，以適應(yīng)左、右采煤工作面的需要。另外，可以很容易將機(jī)尾改裝成機(jī)頭，而適應(yīng)各種特殊情況。此次設(shè)計(jì)的中單鏈型刮板輸送機(jī)的特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單,受力均勻,運(yùn)行平穩(wěn),摩擦阻力小,溜槽利用率高，彎曲性能好,不易出現(xiàn)堵塞，具有很強(qiáng)的適應(yīng)性。

Abstract
The scraper conveyer is the synthesis picking work surface important constituent of the supplementary equipment. It is the first link of the coal shipping. Therefore, the scraper conveyer delivery capacity has decided the mining coal working surface productivity and the efficiency in a great degree; however, our country was lagged behind at present; the scraper conveyer installing equipment power is small. The delivery capacity is low; the transportation is away from short, the durability is bad; Reliability is low; and the life is short. The generalized analysis our country scraper conveyer use present situation, the design manufacture high performance scraper conveyer is imminent. This article first synthesized has compared each kind of type conveyer characteristic, has selected center simple chain according to the actual situation the scraper conveyer. But after, the scraper conveyer has carried on the overall structural design to center simple chain. To the nose transmission device, the aqueduct, the middle trough, the scraper chain, the scraper, the chain wheel, the airplane tail and other major component has carried on the technical analysis and the structural design, has completed center simple chain the scraper conveyer overall design. This design center simple chain about the scraper conveyer two sides are symmetrical, may install the reduction gear on two sidewalls, by left meets, the right mining coal working surface need. Moreover, it may very easily reequip the airplane tail the nose, but adapts each kind of peculiar circumstance. This design of center simple chain of the scraper conveyer characteristic includes: the structure is simple, the stress is even, moves steadily, the friction drag is small, the chute use factor high, the curving performance is good, It is not easy to appear stops up, has the very strong compatibility.

引言
80年代中后期，發(fā)達(dá)國(guó)家紛紛推出全新的高產(chǎn)高效輸送機(jī),其特點(diǎn)為大功率、大運(yùn)量、長(zhǎng)運(yùn)距、高可靠性、長(zhǎng)壽命。而我國(guó)生產(chǎn)技術(shù)落后，目前設(shè)計(jì)生產(chǎn)的刮板輸送機(jī)裝機(jī)功率小,輸送能力低,運(yùn)輸距離短，耐久性差,可靠性低，壽命短，我國(guó)目前的刮板輸送機(jī)的技術(shù)水平只相當(dāng)于80年代初期的國(guó)際水平,落后于國(guó)際先進(jìn)水平10～15年，目前尚沒有自己的高產(chǎn)高效輸送機(jī)，高產(chǎn)高效工作面的配套設(shè)備還只能依靠進(jìn)口。而刮板輸送機(jī)是綜采工作面配套設(shè)備的重要組成部分,是煤炭裝運(yùn)的第一個(gè)環(huán)節(jié),在很大程度上決定了采煤工作面的生產(chǎn)能力和效率，因此，研究制造自己的高產(chǎn)高效輸送機(jī)迫在眉睫。作為新時(shí)代的大學(xué)生，是祖國(guó)的未來，理應(yīng)為祖國(guó)的繁榮昌盛做出自己應(yīng)有的貢獻(xiàn)，結(jié)合中國(guó)的刮板輸送機(jī)現(xiàn)狀，我設(shè)計(jì)了中單鏈型刮板輸送機(jī)，本文首先綜合比較了各種類型輸送機(jī)的特點(diǎn)，根據(jù)實(shí)際情況選用了中單鏈型刮板輸送機(jī)。而后，經(jīng)過半年的思考鉆研對(duì)中單鏈型刮板輸送機(jī)進(jìn)行了總體結(jié)構(gòu)設(shè)計(jì)。對(duì)機(jī)頭傳動(dòng)裝置、過渡槽、中部槽、刮板鏈、刮板、鏈輪、機(jī)尾等主要部件進(jìn)行了技術(shù)分析和結(jié)構(gòu)設(shè)計(jì)，完成了中單鏈型刮板輸送機(jī)的整體設(shè)計(jì)。此次設(shè)計(jì)的中單鏈型刮板輸送機(jī)的特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單,受力均勻,運(yùn)行平穩(wěn),摩擦阻力小,溜槽利用率高，彎曲性能好,不易出現(xiàn)堵塞，具有很強(qiáng)的適應(yīng)性。
