四川圓管輸送(song)機的結構

四川圓(yuan)管輸(shu)送(song)機(ji)設備(bei)輸(shu)送帶的(de)結(jie)構：

圓管帶(dai)(dai)式(shi)輸(shu)(shu)送(song)(song)機(ji)的(de)(de)輸(shu)(shu)送(song)(song)帶(dai)(dai)與普(pu)通(tong)輸(shu)(shu)送(song)(song)帶(dai)(dai)的(de)(de)材料結構(gou)基本相同，根據(ju)不同的(de)(de)承(cheng)載(zai)能力可以(yi)選(xuan)用聚酯棉(mian)帆布帶(dai)(dai)或鋼絲繩芯(xin)(xin)帶(dai)(dai)等。圓管帶(dai)(dai)的(de)(de)芯(xin)(xin)層結構(gou)與普(pu)通(tong)帶(dai)(dai)式(shi)輸(shu)(shu)送(song)(song)機(ji)輸(shu)(shu)送(song)(song)帶(dai)(dai)相比有(you)一定的(de)(de)差別，由于圓管帶(dai)(dai)式(shi)輸(shu)(shu)送(song)(song)帶(dai)(dai)在(zai)運送(song)(song)物料時需形成(cheng)管狀，要(yao)求輸(shu)(shu)送(song)(song)帶(dai)(dai)有(you)良好(hao)的(de)(de)彈性(xing)(xing)(xing)、縱(zong)向柔性(xing)(xing)(xing)、橫向剛性(xing)(xing)(xing)及抗疲勞性(xing)(xing)(xing)能，同時對輸(shu)(shu)送(song)(song)帶(dai)(dai)的(de)(de)芯(xin)(xin)層材料要(yao)求較(jiao)高，輸(shu)(shu)送(song)(song)帶(dai)(dai)搭接(jie)部分要(yao)有(you)良好(hao)的(de)(de)可撓曲性(xing)(xing)(xing)，邊(bian)緣芯(xin)(xin)層設(she)計較(jiao)薄，以(yi)保證輸(shu)(shu)送(song)(song)帶(dai)(dai)在(zai)形成(cheng)管狀后(hou)的(de)(de)密封和穩定性(xing)(xing)(xing)，保證設(she)備在(zai)空載(zai)運行工況下(xia)不易產生扭(niu)轉；同時輸送(song)帶兩邊緣向里側卷(juan)曲(qu)，有助于形成管狀。

  由(you)于圓管帶式輸送機為曲線設置，為維持管狀，需要輸送帶根據設備的布置情況具有一定(ding)的(de)橫(heng)向剛(gang)度，即在曲線段抵抗(kang)輸(shu)(shu)送(song)(song)帶的(de)張力(li)使(shi)其(qi)圓(yuan)(yuan)形發(fa)生改(gai)變的(de)能(neng)力(li)。圓(yuan)(yuan)管(guan)(guan)帶式輸(shu)(shu)送(song)(song)機(ji)的(de)張力(li)、水平轉彎角度越大(da)(da)，需要圓(yuan)(yuan)管(guan)(guan)帶的(de)橫(heng)向剛(gang)度就越大(da)(da)。圓(yuan)(yuan)管(guan)(guan)輸(shu)(shu)送(song)(song)帶的(de)剛(gang)度是(shi)圓(yuan)(yuan)管(guan)(guan)帶式輸(shu)(shu)送(song)(song)機(ji)設計計算的(de)基礎，也是(shi)圓(yuan)(yuan)管(guan)(guan)帶式輸(shu)(shu)送(song)(song)機(ji)同傳統帶式輸(shu)(shu)送(song)(song)機(ji)最本質的(de)區別 。

根據圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)剛(gang)度(du)值的大小指標(biao)(biao)，圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)一般分(fen)為(wei)標(biao)(biao)準(zhun)剛(gang)性(xing)帶(dai)(dai)(dai)、高(gao)剛(gang)性(xing)帶(dai)(dai)(dai)、高(gao)斷面(mian)保(bao)持(chi)型輸送(song)帶(dai)(dai)(dai)三種(zhong)類型。其(qi)中(zhong)標(biao)(biao)準(zhun)剛(gang)性(xing)圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)剛(gang)度(du)最(zui)小，高(gao)斷面(mian)保(bao)持(chi)型圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)剛(gang)度(du)最(zui)大。高(gao)剛(gang)性(xing)圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)比標(biao)(biao)準(zhun)剛(gang)性(xing)圓管(guan)(guan)輸送(song)帶(dai)(dai)(dai)剛(gang)度(du)值高(gao)30%左右，而高斷(duan)面保持(chi)型圓(yuan)管(guan)輸(shu)送(song)帶(dai)的剛(gang)度(du)值更(geng)高。圓(yuan)管(guan)輸(shu)送(song)帶(dai)剛(gang)度(du)值定(ding)義為：將其縱向裁剪成75mm寬后，放在剛(gang)度(du)實驗儀上(shang)測(ce)得(de)的數值。表8-4為標準剛性圓(yuan)管輸送帶的剛度數值。
