金屬(shu)頂(ding)(ding)梁是用于煤礦采煤工作面(mian)、位于單體液壓支柱之(zhi)上頂(ding)(ding)板之(zhi)下(xia)、傳遞頂(ding)(ding)板壓力(li)的支撐梁。
金屬頂梁介紹
金(jin)(jin)屬(shu)頂(ding)(ding)(ding)梁(liang)是用(yong)(yong)于(yu)煤礦(kuang)采(cai)煤工(gong)作(zuo)(zuo)面、位于(yu)單(dan)體液壓支(zhi)(zhi)柱之上頂(ding)(ding)(ding)板(ban)之下、傳(chuan)遞頂(ding)(ding)(ding)板(ban)壓力(li)的(de)(de)支(zhi)(zhi)撐梁(liang)。是煤礦(kuang)采(cai)煤工(gong)作(zuo)(zuo)面支(zhi)(zhi)護(hu)(hu)項板(ban)用(yong)(yong)的(de)(de)頂(ding)(ding)(ding)梁(liang)。按連接方式金(jin)(jin)屬(shu)頂(ding)(ding)(ding)梁(liang)可(ke)分(fen)為(wei)鉸(jiao)接頂(ding)(ding)(ding)梁(liang)和非鉸(jiao)接頂(ding)(ding)(ding)梁(liang)兩(liang)種(zhong)。按頂(ding)(ding)(ding)梁(liang)梁(liang)體截面形狀金(jin)(jin)屬(shu)頂(ding)(ding)(ding)梁(liang)可(ke)分(fen)為(wei)A型、B型、C型、D型頂(ding)(ding)(ding)梁(liang)四種(zhong)。金(jin)(jin)屬(shu)頂(ding)(ding)(ding)梁(liang)可(ke)與各(ge)種(zhong)類型單(dan)體金(jin)(jin)屬(shu)支(zhi)(zhi)柱配合組成金(jin)(jin)屬(shu)支(zhi)(zhi)架，供(gong)煤礦(kuang)在水平及(ji)緩傾斜回采(cai)工(gong)作(zuo)(zuo)面支(zhi)(zhi)護(hu)(hu)的(de)(de)一種(zhong)**度頂(ding)(ding)(ding)梁(liang)由于(yu)這種(zhong)頂(ding)(ding)(ding)梁(liang)能懸壁(bi)支(zhi)(zhi)護(hu)(hu)工(gong)作(zuo)(zuo)面，煤壁(bi)面前邊的(de)(de)運輸機(ji)道上面的(de)(de)頂(ding)(ding)(ding)板(ban)，使煤壁(bi)與支(zhi)(zhi)柱間有較大的(de)(de)支(zhi)(zhi)護(hu)(hu)空間。
