拉繩開關(guān)PLR20-2D-G拉繩開關(guān)PLR20-2D-G拉繩開關(guān)PLR20-2D-G
輸送機(jī)PLR20-2D-G拉繩開關(guān)安裝說明:
1、PLR20-2D-G拉繩開關(guān)成對(duì)安裝在皮帶機(jī)左右兩側(cè),在皮帶機(jī)旁角鐵架鉆Ф12mm孔,用M10×40mm螺栓緊固拉繩開關(guān)。
2、拉繩開關(guān)每隔40米安裝1臺(tái),其位置應(yīng)低于皮帶及便于現(xiàn)場(chǎng)工作人員使用。
3、拉繩系在一關(guān)臂上,拉繩推薦使用覆塑鋼絲繩,直徑3~5mm均可。鋼絲繩用繩夾固定,每隔3米左右安裝一個(gè)托環(huán),以免鋼絲繩垂撓度過大,保證拉繩動(dòng)作可靠。在滿足開關(guān)正常工作的前提下,盡可能拉緊繩索,減少鋼絲繩垂撓度。
4、對(duì)于爬坡段皮帶機(jī),應(yīng)盡量縮短拉繩開關(guān)間距,及拉繩長(zhǎng)度。
5、接線:拉繩開關(guān)出廠時(shí)配有長(zhǎng)度1.2米四芯橡套電纜,芯線上配有1、2、3、4線號(hào),其中1、2為常開接點(diǎn)是報(bào)警信號(hào),3、4為常閉接點(diǎn)是停機(jī)信號(hào)
PLR20-2D-G拉繩開關(guān)介紹:
隨著煤礦生產(chǎn)規(guī)模的擴(kuò)大和生產(chǎn)數(shù)字化程度的提高,對(duì)煤礦安全生產(chǎn)的要求也在不斷提高,作為煤礦生產(chǎn)運(yùn)輸設(shè)備的膠帶輸送機(jī),其安全可靠的運(yùn)行顯得非常重要。本文以礦用膠帶輸送機(jī)常見故障為研究對(duì)象,針對(duì)目前礦用膠帶輸送機(jī)保護(hù)種類不全、可靠性低等問題,結(jié)合單片機(jī)和傳感器技術(shù),對(duì)膠帶輸送機(jī)的保護(hù)系統(tǒng)進(jìn)行了設(shè)計(jì),研究膠帶輸送機(jī)打滑、超溫、跑偏、堆煤、煙霧等常見故障的發(fā)生機(jī)理,設(shè)計(jì)可行的傳感器檢測(cè)方法,通過單片機(jī)對(duì)膠帶輸送機(jī)故障進(jìn)行報(bào)警和控制膠帶輸送機(jī)停機(jī)及相關(guān)保護(hù)裝置動(dòng)作。
