如果說在普通(tong)安防工程(cheng)項目中(zhong)(zhong)(zhong)布(bu)置好線纜(lan)(lan)的(de)難度系數(shu)是7.5分，那么(me)把電梯監(jian)控線纜(lan)(lan)固定、捆好的(de)難度系數(shu)至少在9.0以上(shang)。電梯中(zhong)(zhong)(zhong)如何處理好工程(cheng)中(zhong)(zhong)(zhong)的(de)線纜(lan)(lan)，線纜(lan)(lan)固定、捆扎的(de)方式是非常影響線纜(lan)(lan)的(de)使(shi)用壽命。
對于電梯這樣的復雜的環境，電梯監控線纜是怎么固定與捆扎的呢？
線(xian)纜的固定
1、固定膨脹鏍栓；
2、將(jiang)鋼繩在(zai)膨脹鏍栓上(shang)繞(rao)一圈(quan)；
3、并住鋼繩上緊一(yi)個鎖扣(kou)；
4、調整(zheng)兩(liang)鋼繩(sheng)至受力(li)均衡；
5、擰緊膨(peng)脹(zhang)鏍栓(shuan)上的鏍母，
6、在已緊鎖扣(kou)的(de)上面再(zai)加一鎖扣(kou)（將(jiang)鋼(gang)繩(sheng)頭(tou)回繞幾圈并鎖
捆扎的方法(fa)
捆扎方式(shi)要點(dian)：用三根扎帶做成(cheng)三連(lian)環(huan)(huan)扣(kou)的(de)(de)形式(shi)捆扎，兩(liang)個邊環(huan)(huan)分別捆扎在電梯(ti)數(shu)據(ju)電纜(lan)和電梯(ti)監(jian)控(kong)電纜(lan)上，中(zhong)間的(de)(de)緩沖環(huan)(huan)直徑(jing)控(kong)制在1-1.5公分，數(shu)據(ju)電纜(lan)上的(de)(de)環(huan)(huan)扣(kou)略緊一(yi)點(dian)，以不跑(pao)位為準。監(jian)控(kong)電纜(lan)上的(de)(de)環(huan)(huan)扣(kou)宜松一(yi)點(dian)，以受力時能滑動(dong)為佳。示(shi)圖(tu)：
1、先做電梯數(shu)據(ju)纜線上的扎帶環，
2、再做中間(jian)緩沖環，
3、后(hou)做監控纜(lan)線的扎帶環，
4、調整(zheng)各(ge)環扣至(zhi)要求的松緊（注意將扎(zha)帶接頭調整(zheng)到纜(lan)線(xian)的內側(ce)）。
3捆(kun)扎(zha)(zha)間(jian)(jian)(jian)(jian)(jian)(jian)距(ju)根(gen)據對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)井道環境條(tiao)件(jian)的(de)(de)觀察，并(bing)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)數據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)和(he)監控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)材質(zhi)的(de)(de)分(fen)(fen)析，以(yi)及(ji)互聯網(wang)上眾多(duo)網(wang)友的(de)(de)交流(liu)，認為(wei)捆(kun)扎(zha)(zha)的(de)(de)間(jian)(jian)(jian)(jian)(jian)(jian)距(ju)以(yi)50-80公分(fen)(fen)為(wei)宜。 一(yi)(yi)(yi)是(shi)不(bu)(bu)宜過密(mi)或過疏：過密(mi)則(ze)使兩(liang)(liang)種(zhong)不(bu)(bu)同材質(zhi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)相互牽扯力(li)偏(pian)(pian)大(da)，過疏則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)運(yun)行(xing)中電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)彎曲擺動時(shi)(shi)，兩(liang)(liang)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)分(fen)(fen)離的(de)(de)距(ju)離偏(pian)(pian)大(da)；二是(shi)兩(liang)(liang)端(duan)頭(tou)疏中間(jian)(jian)(jian)(jian)(jian)(jian)密(mi)：在(zai)監控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)兩(liang)(liang)端(duan)頭(tou)的(de)(de)三(san)(san)分(fen)(fen)之一(yi)(yi)(yi)的(de)(de)纜(lan)(lan)(lan)線段(duan)，捆(kun)扎(zha)(zha)間(jian)(jian)(jian)(jian)(jian)(jian)距(ju)宜偏(pian)(pian)疏一(yi)(yi)(yi)些(xie)，而中間(jian)(jian)(jian)(jian)(jian)(jian)的(de)(de)三(san)(san)分(fen)(fen)之一(yi)(yi)(yi)的(de)(de)纜(lan)(lan)(lan)線段(duan)需偏(pian)(pian)密(mi)一(yi)(yi)(yi)些(xie)，這是(shi)因(yin)為(wei)當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)在(zai)最高幾(ji)層(ceng)(ceng)(ceng)或在(zai)最低(di)幾(ji)層(ceng)(ceng)(ceng)時(shi)(shi)，兩(liang)(liang)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)兩(liang)(liang)端(duan)三(san)(san)分(fen)(fen)之一(yi)(yi)(yi)段(duan)錯位(wei)較(jiao)大(da)，而擺動幅(fu)度不(bu)(bu)會太(tai)大(da)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)運(yun)行(xing)在(zai)中間(jian)(jian)(jian)(jian)(jian)(jian)幾(ji)層(ceng)(ceng)(ceng)時(shi)(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)中間(jian)(jian)(jian)(jian)(jian)(jian)三(san)(san)分(fen)(fen)之一(yi)(yi)(yi)段(duan)擺動幅(fu)度會偏(pian)(pian)大(da)而錯位(wei)較(jiao)小。 由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)在(zai)底下幾(ji)層(ceng)(ceng)(ceng)間(jian)(jian)(jian)(jian)(jian)(jian)運(yun)行(xing)的(de)(de)頻率高或停放(fang)的(de)(de)時(shi)(shi)間(jian)(jian)(jian)(jian)(jian)(jian)長，所以(yi)要特別(bie)注意下三(san)(san)分(fen)(fen)之一(yi)(yi)(yi)段(duan)的(de)(de)捆(kun)扎(zha)(zha)間(jian)(jian)(jian)(jian)(jian)(jian)距(ju)。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)三(san)(san)種(zhong)狀態對(dui)比圖：
幾點說明：
1．方案中還有(you)可改(gai)進(jin)之處，即將塑(su)料扎(zha)帶改(gai)換成直徑為(wei)1.5mm左右(you)的單芯金(jin)屬(shu)導線。因(yin)為(wei)一(yi)是(shi)(shi)塑(su)料扎(zha)帶在老(lao)化(hua)脆化(hua)后會崩開，使(shi)得捆扎(zha)的電纜分離，形(xing)成安全隱患(huan)；二是(shi)(shi)單芯金(jin)屬(shu)導線的成形(xing)性能優于塑(su)料扎(zha)帶，有(you)利于做(zuo)監控攬(lan)線的捆扎(zha)環(huan)（不(bu)(bu)(bu)緊不(bu)(bu)(bu)松、纜線能在環(huan)內滑(hua)動），而(er)且既(ji)便是(shi)(shi)外表一(yi)層塑(su)料皮老(lao)化(hua)脆化(hua)，單芯的金(jin)屬(shu)導線也不(bu)(bu)(bu)會斷開。
2．監(jian)控纜(lan)線(xian)的敷(fu)設最好(hao)做到(dao)兩點：一(yi)是保證整輥電纜(lan)平(ping)整地敷(fu)設捆扎(zha)(zha)，避免扭曲(qu)打絞(jiao)；二是先固定電梯轎廂一(yi)端(duan)，再自(zi)下而(er)上地邊敷(fu)設邊捆扎(zha)(zha)，直至到(dao)電梯井道中(zhong)間(jian)偏上的固定點。
3．電(dian)梯轎(jiao)廂一(yi)端的固定方法(fa)：由于不能在轎(jiao)廂上采用(yong)膨(peng)脹鏍栓(shuan)(shuan)，所以就(jiu)盡可(ke)能利用(yong)轎(jiao)廂底部的園滑金屬橫梁來(lai)懸(xuan)掛(gua)監(jian)控(kong)(kong)纜線(xian)的鋼(gang)繩；或者是在轎(jiao)廂底部的垂直鋼(gang)板上鉆孔，用(yong)普通金屬鏍栓(shuan)(shuan)代(dai)替(ti)監(jian)控(kong)(kong)纜線(xian)的懸(xuan)掛(gua)支點。
4．在(zai)監控纜(lan)(lan)線(xian)兩端固定(ding)的(de)時侯(hou)，由于鎖(suo)(suo)扣(kou)最小的(de)規格是4mm，而監控纜(lan)(lan)線(xian)內的(de)鋼(gang)繩(sheng)是2mm左右，為此(ci)，鎖(suo)(suo)扣(kou)往往很難緊(jin)緊(jin)地鎖(suo)(suo)死鋼(gang)繩(sheng)，在(zai)此(ci)情況下有(you)兩種方法：一(yi)(yi)(yi)是將鋼(gang)繩(sheng)在(zai)鎖(suo)(suo)口上加(jia)繞2至3圈(quan)再鎖(suo)(suo)緊(jin)；二是另找(zhao)一(yi)(yi)(yi)段適當長(chang)度、直徑(jing)(jing)為4mm的(de)鋼(gang)繩(sheng)或鋼(gang)絲加(jia)并在(zai)鎖(suo)(suo)扣(kou)內一(yi)(yi)(yi)起鎖(suo)(suo)死。最好(hao)(hao)是采(cai)用(yong)后一(yi)(yi)(yi)種方法。 要說(shuo)的(de)有(you)三(san)(san)點，一(yi)(yi)(yi)是要注意最好(hao)(hao)用(yong)銅線(xian)，如果(guo)用(yong)電話線(xian)，一(yi)(yi)(yi)定(ding)要用(yong)鋁徑(jing)(jing)粗一(yi)(yi)(yi)些的(de)，用(yong)單股就可(ke)以。二是一(yi)(yi)(yi)定(ding)要注意中間(jian)環不(bu)要太小，這(zhe)樣(yang)緩沖作用(yong)就不(bu)明顯(xian)了。三(san)(san)是中間(jian)緊(jin)，兩頭松，一(yi)(yi)(yi)定(ding)要這(zhe)樣(yang)。
