50噸天車滑觸線集電器
滑(hua)觸線(xian)的(de)(de)(de)(de)結構形式多樣(yang)，但(dan)總的(de)(de)(de)(de)原理如下：移動(dong)(dong)設(she)(she)(she)備(bei)(bei)(bei)由于移動(dong)(dong)，需要(yao)不斷地(di)變換位(wei)置(zhi)(zhi)，在每(mei)一個不同的(de)(de)(de)(de)位(wei)置(zhi)(zhi)上(shang)(shang)，移動(dong)(dong)設(she)(she)(she)備(bei)(bei)(bei)又要(yao)隨(sui)時能(neng)獲(huo)得動(dong)(dong)力電(dian)(dian)(dian)源(yuan)，否則就(jiu)(jiu)無法繼(ji)續(xu)移動(dong)(dong)。這(zhe)時，滑(hua)觸線(xian)就(jiu)(jiu)應運(yun)(yun)而(er)生了(le)。我們(men)沿著移動(dong)(dong)設(she)(she)(she)備(bei)(bei)(bei)的(de)(de)(de)(de)運(yun)(yun)行軌道平行敷了(le)若(ruo)干條(tiao)導(dao)體，接通(tong)電(dian)(dian)(dian)源(yuan)。在移動(dong)(dong)的(de)(de)(de)(de)設(she)(she)(she)備(bei)(bei)(bei)上(shang)(shang)，我們(men)又安裝上(shang)(shang)可以(yi)從(cong)導(dao)體上(shang)(shang)取電(dian)(dian)(dian)的(de)(de)(de)(de)集電(dian)(dian)(dian)器(qi)。這(zhe)樣(yang)，當設(she)(she)(she)備(bei)(bei)(bei)移動(dong)(dong)時，集電(dian)(dian)(dian)器(qi)隨(sui)設(she)(she)(she)備(bei)(bei)(bei)同步運(yun)(yun)行，并隨(sui)時從(cong)導(dao)體上(shang)(shang)取得電(dian)(dian)(dian)源(yuan)，提供(gong)給設(she)(she)(she)備(bei)(bei)(bei)，以(yi)使設(she)(she)(she)備(bei)(bei)(bei)可繼(ji)續(xu)移動(dong)(dong)。這(zhe)些導(dao)體和集電(dian)(dian)(dian)器(qi)組成的(de)(de)(de)(de)裝置(zhi)(zhi)就(jiu)(jiu)稱作滑(hua)觸線(xian)。
根據用電設備的不同(tong)，滑(hua)觸(chu)線有(you)多種(zhong)形式，如地(di)鐵，是(shi)用通道側面的鋼(gang)軌(gui)做(zuo)滑(hua)觸(chu)線，工礦企業的橋式吊車是(shi)用三(san)條角鋼(gang)作(zuo)為三(san)相滑(hua)觸(chu)線。
滑觸線(xian)主要(yao)用于各種起重(zhong)運輸(shu)機(ji)械，生產流水線(xian)等需移(yi)動供(gong)電(dian)(dian)的設(she)(she)施和場所，如起重(zhong)機(ji)、裝卸橋、電(dian)(dian)動葫(hu)蘆(lu)、立體倉庫、游(you)樂(le)設(she)(she)備、空調檢測線(xian)等，廣泛應用在起重(zhong)運輸(shu)、電(dian)(dian)力、造船、港(gang)口、冶金(jin)、礦山、水廠、環(huan)保、化工(gong)、家電(dian)(dian)、汽車、服裝、煙(yan)酒、游(you)樂(le)等眾多行(xing)業。

四、吊裝示意圖
注：本裝置一(yi)般采用正裝、側裝方(fang)式。允許多根排列(lie)和(he)制(zhi)彎道（彎道半徑zui小(xiao)不得小(xiao)于 1.5m ）括(kuo)號內尺(chi)寸適(shi)合于200 -300A 的(de)導軌，L 1L 2L 3PE之(zhi)間的(de)間距a為 90mm 。
四、供電方式
在考慮安全滑(hua)觸(chu)線(xian)供(gong)電(dian)(dian)(dian)(dian)(dian)點(dian)的(de)同時應(ying)考慮同跨滑(hua)觸(chu)線(xian)的(de)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)設備的(de)總臺數(shu)總容量，任務(wu)工(gong)作制和全線(xian)長(chang)度(du)的(de)電(dian)(dian)(dian)(dian)(dian)壓降值，及環(huan)境（電(dian)(dian)(dian)(dian)(dian)壓降計算可根據前(qian)面(mian)導軌參數(shu)表的(de)數(shu)據計算）。供(gong)電(dian)(dian)(dian)(dian)(dian)一般有(you)以下(xia)幾(ji)種供(gong)用(yong)(yong)戶參考：①單(dan)端供(gong)電(dian)(dian)(dian)(dian)(dian)；②中部(bu)(bu)供(gong)電(dian)(dian)(dian)(dian)(dian)；③兩(liang)端供(gong)電(dian)(dian)(dian)(dian)(dian)；④兩(liang)端1/6處供(gong)電(dian)(dian)(dian)(dian)(dian)；⑤兩(liang)端正(zheng)/10處和中部(bu)(bu)三點(dian)供(gong)電(dian)(dian)(dian)(dian)(dian)等。
五、安裝說明
在安裝滑觸線前先將角鋼支架按照用戶選擇的安裝形式，根據滑觸線的懸掛間距固定好，在安裝現場把每6米一根的滑觸線上套上所需的懸掛座，和兩端接頭護套各一個，還在一端裝上鋁接頭一個，裝鋁接頭時應注意只能將鋁導軌伸進接頭的1/2留給另一根導軌連接用，以上工作準備好后，再把一根一根的滑觸線懸掛在支架上，進行全線連接，連接時應擰緊每個接頭的螺絲。在滑觸線全線長超過200米時應加裝伸縮裝置（伸縮裝置本廠隨時供應），在引接電源線進線時，可在每6米一根的接頭處引接，具體接法可參照前面接頭裝置圖。
在安裝彎道滑觸線時，懸吊距離應相應縮短，具體尺寸可根據現場條件而定。
在安(an)(an)裝(zhuang)導(dao)(dao)電器(qi)時先把(ba)導(dao)(dao)電器(qi)裝(zhuang)在配(pei)套的方(fang)管上，選擇與(yu)(yu)(yu)滑(hua)觸(chu)(chu)線配(pei)合的適當位置固定(ding)在用電設備(bei)上，應(ying)注意為使(shi)導(dao)(dao)電器(qi)與(yu)(yu)(yu)滑(hua)觸(chu)(chu)線有(you)很好的跟蹤性能和良好的接觸(chu)(chu)能力，導(dao)(dao)電器(qi)與(yu)(yu)(yu)滑(hua)觸(chu)(chu)線應(ying)安(an)(an)裝(zhuang)在同(tong)一垂直、水平(ping)方(fang)向。
六(liu)、維(wei)護保養
安全滑觸線在正常運行中應做定期檢查，因為用電設備是每個工礦企業的主要生產工具，稍有差錯就會直接影響工廠的生產效益。在檢查滑觸線時應檢查每6米一個接頭處是否有松動、脫開，在檢查導電器時，應檢查活動部位是否轉動靈活，拉簧是否疲勞，電刷磨損等情況（這些情況都會影響到滑觸線導電性能和導電器的跟蹤性能。應及時作好調整）。
節假日設備整修期，將導(dao)(dao)電(dian)器(qi)(qi)脫(tuo)出導(dao)(dao)管，檢查導(dao)(dao)電(dian)器(qi)(qi)電(dian)刷(shua)(shua)滾輪磨損(sun)情況，如電(dian)刷(shua)(shua)伸出量(liang)小于(yu)規定有(you)效長度時，要及時更換(huan)，導(dao)(dao)向滾輪變(bian)形嚴重(zhong)時，亦需更換(huan)，以保持導(dao)(dao)電(dian)器(qi)(qi)運行正常(chang)和電(dian)刷(shua)(shua)的(de)良好接觸，并清(qing)查造成的(de)原(yuan)因(yin)。安全滑觸線所有(you)零(ling)部件(jian)中，電(dian)刷(shua)(shua)是*正常(chang)會(hui)磨損(sun)的(de)零(ling)件(jian)。
