立式接(jie)鏈(lian)(lian)環(huan)(huan)為目前比較常用(yong)的(de)一(yi)種(zhong)礦(kuang)用(yong)鏈(lian)(lian)條(tiao)用(yong)接(jie)鏈(lian)(lian)環(huan)(huan)，主要(yao)由兩個半(ban)環(huan)(huan)和彈(dan)銷(xiao)組成。兩半(ban)環(huan)(huan)分別連(lian)(lian)接(jie)鏈(lian)(lian)條(tiao)兩端的(de)第二鏈(lian)(lian)環(huan)(huan)、第三鏈(lian)(lian)環(huan)(huan)，鎖緊后嵌(qian)入彈(dan)性彈(dan)銷(xiao)，使其結合(he)牢固，避免(mian)脫鏈(lian)(lian)。有(you)的(de)接(jie)鏈(lian)(lian)環(huan)(huan)中間設計有(you)連(lian)(lian)接(jie)部分，有(you)的(de)中間空開，由其安裝方法與連(lian)(lian)接(jie)齒(chi)(chi)形(xing)（鋸齒(chi)(chi)、弧(hu)齒(chi)(chi)、卡塊）決(jue)定(ding)。

　　當使用不(bu)當在刮板(ban)機機頭下(xia)方(fang)造成堆鏈(lian)(lian)(lian)(lian)時易(yi)出現問題，此時接鏈(lian)(lian)(lian)(lian)環(huan)(huan)A點受到摩(mo)擦力(li)F和(he)刮板(ban)機底板(ban)的(de)(de)壓力(li)N作用。而(er)f=μ*N，μ為(wei)摩(mo)擦系(xi)數。N由diyi鏈(lian)(lian)(lian)(lian)環(huan)(huan)、dier鏈(lian)(lian)(lian)(lian)環(huan)(huan)、disan鏈(lian)(lian)(lian)(lian)環(huan)(huan)向(xiang)(xiang)下(xia)的(de)(de)部分重(zhong)力(li)、接鏈(lian)(lian)(lian)(lian)環(huan)(huan)的(de)(de)自身重(zhong)力(li)和(he)左端(duan)其(qi)他(ta)鏈(lian)(lian)(lian)(lian)條對接鏈(lian)(lian)(lian)(lian)環(huan)(huan)向(xiang)(xiang)下(xia)的(de)(de)拉力(li)分量組成。在這種情況下(xia)，如果要(yao)拉開(kai)鏈(lian)(lian)(lian)(lian)條，將(jiang)接鏈(lian)(lian)(lian)(lian)環(huan)(huan)逆(ni)時針(zhen)轉動至水平方(fang)向(xiang)(xiang)。拉力(li)F1越(yue)(yue)大(da)，N越(yue)(yue)大(da)，從(cong)而(er)摩(mo)擦力(li)f越(yue)(yue)大(da)。而(er)且(qie)接鏈(lian)(lian)(lian)(lian)環(huan)(huan)越(yue)(yue)長，α角越(yue)(yue)小，越(yue)(yue)不(bu)容易(yi)拉開(kai)。所以在拉開(kai)鏈(lian)(lian)(lian)(lian)環(huan)(huan)的(de)(de)過(guo)程中，由于在寬度(du)(du)方(fang)向(xiang)(xiang)失效需要(yao)施加的(de)(de)力(li)要(yao)遠小于長度(du)(du)方(fang)向(xiang)(xiang)需要(yao)施加的(de)(de)力(li)，接鏈(lian)(lian)(lian)(lian)環(huan)(huan)易(yi)從(cong)寬度(du)(du)方(fang)向(xiang)(xiang)脫鏈(lian)(lian)(lian)(lian)。接鏈(lian)(lian)(lian)(lian)環(huan)(huan)為(wei)易(yi)損件，正常情況下(xia)，接鏈(lian)(lian)(lian)(lian)環(huan)(huan)的(de)(de)脫鏈(lian)(lian)(lian)(lian)方(fang)向(xiang)(xiang)為(wei)長度(du)(du)方(fang)向(xiang)(xiang)。
