電梯蹲底和沖頂***原因分析電梯在正常運(yùn)行時(shí)發(fā)生的蹲底或沖頂***原因1、電氣安全裝置失靈A、強(qiáng)迫減速裝置失靈。當(dāng)電梯失控沖向井道頂端或底部時(shí)，商丘電梯改造價(jià)格，商丘電梯改造價(jià)格，首先經(jīng)過的是強(qiáng)迫減速開關(guān)，如果這一開關(guān)失靈或減速繼電器出頭粘連不釋放，電梯到達(dá)端站前不能減速，即轎廂仍以恒速運(yùn)行直至蹲底或沖頂；B、位置開關(guān)失靈。如果強(qiáng)迫減速開關(guān)未能使電梯減速、停止，特別是當(dāng)電梯以滿載下行越出底層位置后，下限位開關(guān)失效，不能斷開控制電路使制動(dòng)器抱閘，即使極限開關(guān)有效，電梯也將發(fā)生蹲底***。因此電梯到達(dá)極限開關(guān)位置后，轎廂撞板與緩沖器頂面的距離*有150mm~200mm。在這有限的距離內(nèi)能否平穩(wěn)地制停轎廂？從運(yùn)動(dòng)學(xué)上考慮，制停距離主要決定于運(yùn)動(dòng)物體的慣性的制動(dòng)力的大小，設(shè)定制動(dòng)力恒定不變，那么慣性越大，則制動(dòng)減速越慢，制動(dòng)距離越長(zhǎng)。對(duì)滿載下行又未經(jīng)減速的電梯來說，要想制停轎廂，不發(fā)生蹲底***是不可能的C、開關(guān)失靈，商丘電梯改造價(jià)格。在強(qiáng)迫減速開關(guān)、限位開關(guān)均失靈的條件下，如極限開關(guān)失效，蹲底或沖頂***將不可避免；D、方向接觸器粘連或釋放遲緩造成制動(dòng)器不抱閘或抱閘時(shí)間滯后。2、制動(dòng)力矩不足制動(dòng)器的制動(dòng)性能是電梯安全運(yùn)行的一個(gè)重要指標(biāo)。GB10060規(guī)定。電梯的運(yùn)行速度不論是上行還是下行，均應(yīng)在規(guī)定的額定速度范圍內(nèi)運(yùn)行。商丘電梯改造價(jià)格</p><div

加固：電梯坑一般配備雙向連續(xù)加固，沖裁應(yīng)有意識(shí)，保證足夠的保護(hù)層厚度。 </p> <p> 模板：建議盡量采用舊木模板作為設(shè)置配置，現(xiàn)場(chǎng)直接安裝。注意模板轉(zhuǎn)角處應(yīng)設(shè)木背楞，使兩塊連接牢固；模板下口及鋼筋應(yīng)預(yù)留足夠厚度的保護(hù)層?？由顣r(shí)，應(yīng)考慮模板的抗浮措施；在條件允許的情況下，也可在設(shè)置木模板的轉(zhuǎn)角處和混凝土的接觸面處設(shè)置鐵皮，以保證模板不受應(yīng)力變形與混凝土熔融時(shí)鋼模板難以拆除；不建議使用鋼模板，因?yàn)殇撃０寰哂袆偠却螅D(zhuǎn)角受力時(shí)易錯(cuò)縫，造成拆模困難，小型鋼模板損壞，后期鑿毛量增加。 </p> <p> 2、電梯井道 </p> <p> 增強(qiáng)層：韌帶情況下電梯豎井入口時(shí)下飼料應(yīng)確保冷凝0.5?1.0厘米孔大小，以防止露筋意識(shí)的方式。 </p> <p> 3、電梯軸普遍存在于剪力墻結(jié)構(gòu)中。當(dāng)水平施工節(jié)點(diǎn)離開時(shí)，應(yīng)將施工節(jié)點(diǎn)抬高3~5cm，以便于垂直模板支撐。 </p> <p> 4、在電梯豎井與除了桅桿的勃起于滿足安全性和技術(shù)要求的結(jié)構(gòu)中，我們還需要滿足電梯設(shè)備，如從井道壁的距離;井道支架的架設(shè)之初，責(zé)任工程師應(yīng)將技術(shù)，考慮貨架程序是合理的，應(yīng)參照找出合同是否應(yīng)被視為架電梯的安裝要求，避免不必要的返工未來責(zé)任的范圍內(nèi);與層增加阱層應(yīng)經(jīng)常檢查井架卸料情況。

如何防范電梯故障一、斷相引起停梯當(dāng)三相電源出現(xiàn)斷相時(shí)，相序繼電器動(dòng)作切斷安全回路，使電梯停止運(yùn)行。這種故障多出在繼電器邏輯控制的電梯，因?yàn)槭抢鲜诫娞?，電源開關(guān)多為閘刀式，電源經(jīng)過極限開關(guān)，再送至電梯控制柜、電源流經(jīng)的兩個(gè)開關(guān)，共六根保險(xiǎn)絲。電梯運(yùn)行、起動(dòng)，電流都很大。經(jīng)過一段時(shí)間運(yùn)行，如維保人員不及時(shí)檢查，保險(xiǎn)絲與螺絲連接處極易燒斷，電梯斷相，引起停梯，輕則關(guān)人，重則發(fā)生危害。主要預(yù)防措施：a.保養(yǎng)人員要經(jīng)常巡視檢查，發(fā)現(xiàn)可疑之處，及時(shí)修理，出現(xiàn)發(fā)燙、打火花諸類情形應(yīng)立即更換。b.建議用戶將閘刀開關(guān)更換為相當(dāng)容量的空氣開關(guān)。c.現(xiàn)在設(shè)計(jì)的電梯都沒有電源極限開關(guān)，筆者認(rèn)為，可以就安全回路略作改動(dòng)，即加裝上、下極限電氣開關(guān)串聯(lián)在安全回路中，拆除原極限開關(guān)。經(jīng)過，此故障可徹底排除。二、漲繩輪開關(guān)斷開引起停梯像曳引繩一樣，限速器繩同樣會(huì)在使用過程中伸長(zhǎng)。由于底坑漲繩輪重錘的作用，漲繩輪開關(guān)打板偏移，直到斷開開關(guān)導(dǎo)致停梯。這種故障，對(duì)于新裝電梯，維保人員須每月檢查一次，運(yùn)行一年以后，三個(gè)月檢查一次，如此即可防患于未然。筆者遇到過數(shù)起因老鼠掉在底坑內(nèi)，竄進(jìn)漲繩輪而引起三個(gè)開關(guān)同時(shí)動(dòng)作的現(xiàn)象。
