我們在(zai)礦井提(ti)(ti)升(sheng)時怎樣選擇(ze)鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng),在(zai)礦井提(ti)(ti)升(sheng)中(zhong)，根據用(yong)(yong)途不同(tong)有(you)提(ti)(ti)升(sheng)鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(主繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng))，平(ping)衡鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(尾繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng))，罐道鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，防(fang)撞鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，防(fang)墜(zhui)器的(de)制動鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)和緩(huan)沖鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)等。  1. 礦用(yong)(yong)提(ti)(ti)升(sheng)鋼(gang)(gang)(gang)絲(si)(si)繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)都是絲(si)(si)→股(gu)→繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)結構，即先(xian)由鋼(gang)(gang)(gang)絲(si)(si)捻(nian)成繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)股(gu)，再由繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)股(gu)捻(nian)成繩(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)， 2. 鋼(gang)(gang)(gang)絲(si)(si)的(de)韌性：有(you)特(te)號(hao)、Ⅰ號(hao)、Ⅱ號(hao)三(san)種。提(ti)(ti)物(wu)可用(yong)(yong)特(te)號(hao)和Ⅰ號(hao)，提(ti)(ti)人(ren)必須用(yong)(yong)特(te)號(hao)! 3. 抗腐(fu)能(neng)力：有(you)鍍(du)鋅(xin)鋼(gang)(gang)(gang)絲(si)(si)(鋼(gang)(gang)(gang)絲(si)(si)表(biao)面鍍(du)鋅(xin))和光(guang)面鋼(gang)(gang)(gang)絲(si)(si)(鋼(gang)(gang)(gang)絲(si)(si)表(biao)面未鍍(du)鋅(xin))

4.  繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)的(de)(de)結(jie)構和(he)作用(yong)(yong)：  1）結(jie)構：繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)由金屬繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)和(he)纖(xian)(xian)維(wei)繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)，金屬繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)由鋼(gang)絲(si)(si)(si)(si)制(zhi)(zhi)成，纖(xian)(xian)維(wei)繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)由創麻、黃麻等制(zhi)(zhi)成。  2）作用(yong)(yong)： a 支持(chi)繩(sheng)(sheng)(sheng)(sheng)股，保持(chi)鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)的(de)(de)截面形狀，減少(shao)鋼(gang)絲(si)(si)(si)(si)的(de)(de)擠(ji)(ji)壓和(he)變形，減少(shao)繩(sheng)(sheng)(sheng)(sheng)段間(jian)鋼(gang)絲(si)(si)(si)(si)的(de)(de)接觸應力。 b 繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)富于彈性，在鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)彎曲時(shi)，允許繩(sheng)(sheng)(sheng)(sheng)股間(jian)和(he)鋼(gang)絲(si)(si)(si)(si)間(jian)有相對(dui)移動，以緩(huan)和(he)彎曲應力，使(shi)鋼(gang)絲(si)(si)(si)(si)富有韌性。  c 貯存潤滑(hua)油(you)(you)，預防鋼(gang)絲(si)(si)(si)(si)內部(bu)銹蝕，減少(shao)鋼(gang)絲(si)(si)(si)(si)間(jian)的(de)(de)摩擦。戈培油(you)(you) 。   鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)的(de)(de)特性：   1、 金屬繩(sheng)(sheng)(sheng)(sheng)芯(xin)(xin)(xin)鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)破(po)斷力大，抗沖(chong)擊及抗擠(ji)(ji)壓性能好，耐(nai)高溫。   2、 天(tian)然纖(xian)(xian)維(wei)芯(xin)(xin)(xin)（棉紗、黃麻、劍(jian)麻）儲(chu)油(you)(you)多(duo)，鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)在工(gong)作時(shi)，內部(bu)有足夠的(de)(de)潤滑(hua)，并防止(zhi)鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)銹蝕。   3、 合成纖(xian)(xian)維(wei)芯(xin)(xin)(xin)（聚乙烯、聚丙(bing)烯）具有韌性好、不吸水、耐(nai)酸、耐(nai)堿、耐(nai)擠(ji)(ji)壓和(he)耐(nai)磨(mo)損等優(you)點(dian)。鋼(gang)絲(si)(si)(si)(si)繩(sheng)(sheng)(sheng)(sheng)在動載荷使(shi)用(yong)(yong).
