【正文】 內(nèi)廠家只要改變觀念，狠抓質(zhì)量，充分利用最新技術(shù)，根據(jù)市場(chǎng)需求不斷開發(fā)出新的產(chǎn)品，必定可以搶回國(guó)外品牌占領(lǐng)的高端市場(chǎng)。 第一，發(fā)展帶式輸送機(jī)綜合保護(hù)自動(dòng)化系統(tǒng)。 帶式輸送機(jī)綜合保護(hù)自動(dòng)化系統(tǒng)與帶式輸送機(jī)控制系統(tǒng)互相連接通訊，參與到整個(gè)帶式輸送機(jī)控制系統(tǒng)的邏輯控制過程中，可充分發(fā)揮保護(hù)裝置的作用。結(jié)構(gòu)緊湊、安裝簡(jiǎn)便、性能可靠、免維護(hù) 是未來各種狀態(tài)檢測(cè)裝置發(fā)展的必然方向。 針對(duì)實(shí)際應(yīng)用中接觸式測(cè)量方式存在的缺點(diǎn)，可以盡量采用非接觸式測(cè)量技術(shù)手段，以減少對(duì)現(xiàn)場(chǎng)工藝流程的影響，并可以大大延長(zhǎng)保護(hù)裝置的使用壽命、減輕檢修維護(hù)的負(fù)擔(dān)，如非接觸型的感應(yīng)式跑偏開關(guān)和感應(yīng)式料流開關(guān)等。 針對(duì)料流開關(guān)只能單點(diǎn)測(cè)量的缺點(diǎn)，可以將皮帶秤的實(shí)時(shí)流量和帶速以及物料流向相結(jié)合，在工業(yè)控制計(jì)算機(jī)的人機(jī)界面上通過軟件技術(shù)合成與現(xiàn)場(chǎng)相一致的流量動(dòng)態(tài)曲線，更為形象具體地顯示現(xiàn)場(chǎng)輸送帶 的物料的流量流速以及不同位置的物料多少。有不少?gòu)S家已經(jīng)開發(fā)出了一些功能先進(jìn)的產(chǎn)品，但是要能夠獲得市場(chǎng)認(rèn)可還必須提高產(chǎn)品質(zhì)量、加大推廣力度。 4 結(jié)束語 目前我國(guó)廠礦企業(yè)正處在從粗放型向集約型、從勞動(dòng)密集型向技術(shù)密集型模式轉(zhuǎn)變的過程之中，如何在減少人員投入的情況下，又能保證生產(chǎn)安全、增加效率和效益、提高自身的市場(chǎng)競(jìng)爭(zhēng)力，是擺在每個(gè)企業(yè)面前的一個(gè)重要課題。 5 附錄 B Application and development of the conveyer protector Foreword The bringing type conveyer is that a kind of supplies employed in the industrial enterprise extensively transport the apparatus, mainly made up of conveyer belt and driving the electrical machinery and supporting the apparatus, control and protector,etc.. Usually one grade of antithetical couplets make up an intact conveyer system alternately each other by several strip type conveyers, realize the transport at a long distance of the supplies. The operation conditions directness of the bringing type conveyer concerns the security for producing apparatus and personnel in the course. How make conveyer protector of bringing etc. highefficiently and reliably and steadily in produce operate, functioning, having important realistic meaninging very fully. The target that this text discusses is mainly a pull switch, run, lean towards switch, skid switch, tear, split open, imprison, material flow switch, stop up material switch first protector of conveyer of bringing etc.. Current application situations and existing problem. Pull switch used for person who bring conveyer first kind of emergency shutdown operate protectors live. The pull switch employed extensively at present is generally a passive machinery type twoway pull switch, mainly have rotating type two kinds cam structure and portable cam structure. Movement journey loud, the sensitivity is high and difficult to be seized rotate, because of cam pull switch pendulum rod of structure of rotating etc., so adopted more at present. Pull switch fixed to install on conveyer both sides support of bringing etc. according to certain interval (about 40m), tie and draw the rope each other. Under the emergency, can arbitrary seat pulls and plays the rope in conveyer of bringing etc., touch off switch movements and realize emergency shutdown. The way of restoring to the throne after the movements of the pull switch is divided into and reset automatically and is restored to the throne two kinds manually. 劉寶興：大傾角膠帶輸送機(jī)控制系統(tǒng)設(shè)計(jì) 6 Pull switch usually often closes, often turns on each one in the joint, use and often close the joint the same. Because there is more quantity of pull switches, for save cable, one strip type conveyer all pull switch close joint insert person who bring divideshut brake of conveyer control the return circuit connect in series, often usually。 As to long conveyer of bringing etc. very, adopt, run, lean towards switch di
