  • 金屬頂梁

       金屬(shu)頂(ding)(ding)梁是(shi)用于煤礦(kuang)采煤工作面、位(wei)于單(dan)體液壓(ya)支柱(zhu)之上頂(ding)(ding)板之下、傳遞頂(ding)(ding)板壓(ya)力的支撐(cheng)梁。


        金屬頂梁介紹


    金(jin)屬(shu)頂(ding)(ding)(ding)(ding)梁(liang)是(shi)用(yong)于(yu)煤(mei)(mei)礦(kuang)采(cai)(cai)煤(mei)(mei)工(gong)作(zuo)面(mian)、位于(yu)單(dan)體液壓支(zhi)(zhi)柱之上(shang)(shang)頂(ding)(ding)(ding)(ding)板之下、傳遞頂(ding)(ding)(ding)(ding)板壓力的(de)(de)支(zhi)(zhi)撐梁(liang)。是(shi)煤(mei)(mei)礦(kuang)采(cai)(cai)煤(mei)(mei)工(gong)作(zuo)面(mian)支(zhi)(zhi)護(hu)(hu)項板用(yong)的(de)(de)頂(ding)(ding)(ding)(ding)梁(liang)。按連接(jie)方式金(jin)屬(shu)頂(ding)(ding)(ding)(ding)梁(liang)可(ke)分為鉸接(jie)頂(ding)(ding)(ding)(ding)梁(liang)和非鉸接(jie)頂(ding)(ding)(ding)(ding)梁(liang)兩種。按頂(ding)(ding)(ding)(ding)梁(liang)梁(liang)體截面(mian)形狀金(jin)屬(shu)頂(ding)(ding)(ding)(ding)梁(liang)可(ke)分為A型(xing)(xing)(xing)(xing)、B型(xing)(xing)(xing)(xing)、C型(xing)(xing)(xing)(xing)、D型(xing)(xing)(xing)(xing)頂(ding)(ding)(ding)(ding)梁(liang)四種。金(jin)屬(shu)頂(ding)(ding)(ding)(ding)梁(liang)可(ke)與(yu)各種類(lei)型(xing)(xing)(xing)(xing)單(dan)體金(jin)屬(shu)支(zhi)(zhi)柱配合組(zu)成金(jin)屬(shu)支(zhi)(zhi)架,供煤(mei)(mei)礦(kuang)在水平及緩傾斜回采(cai)(cai)工(gong)作(zuo)面(mian)支(zhi)(zhi)護(hu)(hu)的(de)(de)一種**度(du)頂(ding)(ding)(ding)(ding)梁(liang)由于(yu)這種頂(ding)(ding)(ding)(ding)梁(liang)能懸壁(bi)支(zhi)(zhi)護(hu)(hu)工(gong)作(zuo)面(mian),煤(mei)(mei)壁(bi)面(mian)前邊的(de)(de)運輸機(ji)道上(shang)(shang)面(mian)的(de)(de)頂(ding)(ding)(ding)(ding)板,使煤(mei)(mei)壁(bi)與(yu)支(zhi)(zhi)柱間有較(jiao)大的(de)(de)支(zhi)(zhi)護(hu)(hu)空間。
