【正文】 lice and can touch off emergency shutdown automatically initial stage in hopper, thus the conveyer belt preventing a large number of pieces of material from causing skids, drives serious consequences such as the overload of the electrical machinery,etc.. Stop up the material switch to divide according to different detection means and operation principle, have, hinder person who fasten mainly, radio frequency lead person who receive, electrode type, tuning fork type, activity block modes in Chinese operatic music, negative pressure type various forms. 2 questions are summarized From investigate situation may find out the majority of product store problems in of practical application, domestic products lack, improve, make a lot of problems not solved pletely for a long time. For many years, domestic brand low price petition cause product quality and after sale service quality can make user to be satisfied each other, and performance and quality to the apparatus of user in the coal, electricity, petrochemical industry, port,etc. are expected very much, they would rather often spend several times even price in the domestic products of more than ten times choosing the foreign imported brand products. On the whole, person who bring conveyer protector products have function single, performance lag behind, structure plicated, appearance coarse, dependability shorting such as being poor at home. The advanced product market is basically dismembered by foreign countries brand, there is not a brand with stronger petitiveness and influence yet at home. In addition, it is a very different important reason of bringing type conveyer protector product quality at home too to lack the sector standard. In fact, the bringing type conveyer protector market demand of the products is very enormous, the domestic producer only changes the idea, take charge of quality severely, fully utilize the latest technology, developing the new products constantly according to market 9 demand, can certainly reseize the advanced market that the foreign brand is being captured.。 Kinds of the switch are many to skid, operation principle and detection method have nothing in mon with each other. Divide according to detection method, have, measure 7 conveyer belt pace and touching, skidding switching while being wheeled pared with standard pace established directly, measure from the rotational speed of the driving wheel and switch of skidding pared with standard rotational speed established, have difference measure cylinder rotational speed and conveyer belt pace and contrast type pared to go on skid switch at the same time。包括帶式輸送機(jī)保護(hù)裝置在內(nèi)的狀態(tài)檢測裝置的改進(jìn)必定能夠提高廠礦企業(yè)設(shè)備運(yùn)行的可靠性、穩(wěn)定性，并最終體現(xiàn)為生產(chǎn)效率的提高。 以上分別從功能、結(jié)構(gòu)、性能等方面探討了帶式輸送機(jī)保護(hù)裝置的發(fā)展方向。 第三，應(yīng)用新的檢測技術(shù)和檢測手段，針對當(dāng)前帶式輸送機(jī)保護(hù)裝置使用過程中的缺點和不足，開發(fā)更能有效反映輸送機(jī)運(yùn)行狀態(tài)的、性能更為可靠和穩(wěn)定的保護(hù)裝置。發(fā)展智能化保護(hù)裝置，使現(xiàn)場保護(hù)裝置具備通信功能；應(yīng)用通 信和地址編碼技術(shù)，集中對安裝在現(xiàn)場的整個帶式輸送機(jī)系統(tǒng)的所有保護(hù)裝置進(jìn)行監(jiān)視和控制，實現(xiàn)遠(yuǎn)方狀態(tài)顯示以及遠(yuǎn)方復(fù)位等功能。另外，缺少行業(yè)標(biāo)準(zhǔn)也是國內(nèi)帶式輸送機(jī)保護(hù)裝置產(chǎn)品質(zhì)量良莠不齊的一個重要原因。 2 問題總結(jié) 從調(diào)查情況可以看出，大部分產(chǎn)品在實際應(yīng)用中都存在不少問題，國內(nèi)產(chǎn)品長期以來缺乏改進(jìn)也使得很多問題一直沒有得到徹底解決。 堵料開關(guān) 3 堵料開關(guān)是安裝在落料斗或儲料倉內(nèi)檢測料位的一種保護(hù)裝置。 按照不同的檢測手段和工作原理劃分，有安裝于輸送帶下方的光電式和導(dǎo)電橡膠式撕裂
