行車滑(hua)(hua)(hua)(hua)觸線又稱滑(hua)(hua)(hua)(hua)觸線，安全滑(hua)(hua)(hua)(hua)觸線。用(yong)于給(gei)移動(dong)中的設(she)備供電(dian)(dian)，由(you)兩部分(fen)組成，滑(hua)(hua)(hua)(hua)線導(dao)軌(gui)（固定(ding)部分(fen)，與(yu)電(dian)(dian)源相接，常(chang)導(dao)軌(gui)由(you)單長4.5m/根(gen)或者6米/根(gen)連(lian)(lian)接而成），集電(dian)(dian)器(qi)（滑(hua)(hua)(hua)(hua)動(dong)部分(fen)，可在滑(hua)(hua)(hua)(hua)線軌(gui)道上(shang)或內滑(hua)(hua)(hua)(hua)動(dong)并與(yu)銅(tong)條接觸取電(dian)(dian)，集電(dian)(dian)器(qi)用(yong)于與(yu)移動(dong)電(dian)(dian)機相連(lian)(lian)）。

安全滑觸線在(zai)(zai)正(zheng)常運(yun)行中(zhong)應做定(ding)期檢(jian)(jian)查，因為(wei)用電(dian)設備(bei)是(shi)每(mei)個工(gong)(gong)礦企業的主要生產工(gong)(gong)具，稍(shao)有差(cha)錯就會直接影響工(gong)(gong)廠的生產效益。在(zai)(zai)檢(jian)(jian)查滑觸線時應檢(jian)(jian)查每(mei)6米一個接頭處是(shi)否有松(song)動(dong)、脫開，在(zai)(zai)檢(jian)(jian)查導電(dian)器(qi)時，應檢(jian)(jian)查活(huo)動(dong)部位(wei)是(shi)否轉動(dong)靈(ling)活(huo)，拉簧是(shi)否疲勞，電(dian)刷磨損等情況(kuang)（這些情況(kuang)都會影響到滑觸線導電(dian)性(xing)能(neng)和(he)導電(dian)器(qi)的跟蹤性(xing)能(neng)。應及時作好調整）。

節假日(ri)設備(bei)整修期，將導(dao)電(dian)器(qi)脫(tuo)出(chu)導(dao)管(guan)，檢查導(dao)電(dian)器(qi)電(dian)刷(shua)滾輪磨損情況，如電(dian)刷(shua)伸出(chu)量小于規定有(you)效長度時，要及時更換，導(dao)向滾輪變(bian)形嚴重時，亦需更換，以保持導(dao)電(dian)器(qi)運行正(zheng)常和(he)電(dian)刷(shua)的(de)(de)良好接觸，并清查造(zao)成的(de)(de)原因。安全(quan)滑觸線(xian)所有(you)零(ling)部件(jian)中(zhong)，電(dian)刷(shua)是唯壹正(zheng)常會(hui)磨損的(de)(de)零(ling)件(jian)。
