潛孔鉆機的辦公的作業流程 潛孔鉆機的崗位原因和普普通通突破轉臂式風動鑿巖機相似。風動鑿巖機將突破轉臂平臺做在混著,突破能使用鉆桿傳播給合金麻花鉆;而潛孔鉆機將突破平臺(突破器)單獨出現,放進孔底,究竟鉆孔設備多深,合金麻花鉆就是一直裝在突破器上,不用了使用鉆桿傳播突破能,而使下降了突破能的折損。潛(qian)(qian)(qian)(qian)孔(kong)(kong)鉆(zhan)機(ji)的(de)(de)(de)鑿巖(yan)機(ji)跟隨轉(zhuan)孔(kong)(kong)深入的(de)(de)(de)新增(zeng),鑿巖(yan)特性在(zai)潛(qian)(qian)(qian)(qian)桿(gan)、直接(jie)頭(中(zhong)深孔(kong)(kong)轉(zhuan)孔(kong)(kong))等處(chu)的(de)(de)(de)損失(shi)增(zeng)大,鉆(zhan)孔(kong)(kong)速度明顯下(xia)降,成本增(zeng)加。為了(le)減少(shao)能力(li)(li)的(de)(de)(de)損失(shi),提高鉆(zhan)孔(kong)(kong)效率,實際工(gong)程中(zhong)設計出了(le)潛(qian)(qian)(qian)(qian)孔(kong)(kong)鉆(zhan)機(ji)。潛(qian)(qian)(qian)(qian)孔(kong)(kong)鉆(zhan)機(ji)也是(shi)以壓(ya)縮空(kong)氣為動力(li)(li),回(hui)轉(zhuan)沖(chong)擊(ji)(ji)破碎巖(yan)石(shi)(shi)來成孔(kong)(kong)的(de)(de)(de)。其工(gong)作(zuo)原理是(shi),潛(qian)(qian)(qian)(qian)孔(kong)(kong)鉆(zhan)的(de)(de)(de)風動沖(chong)擊(ji)(ji)器連(lian)同鉆(zhan)頭裝(zhuang)在(zai)釬桿(gan)的(de)(de)(de)前端,鉆(zhan)孔(kong)(kong)時,推進(jin)機(ji)構使鉆(zhan)具(ju)連(lian)續(xu)(xu)推進(jin)并(bing)將(jiang)一定的(de)(de)(de)軸(zhou)向(xiang)(xiang)壓(ya)力(li)(li)施加于孔(kong)(kong)底,使鉆(zhan)頭與孔(kong)(kong)底巖(yan)石(shi)(shi)相接(jie)觸(chu);回(hui)轉(zhuan)機(ji)構使鉆(zhan)具(ju)連(lian)續(xu)(xu)回(hui)轉(zhuan),安裝(zhuang)在(zai)鉆(zhan)桿(gan)前面的(de)(de)(de)沖(chong)擊(ji)(ji)器,在(zai)壓(ya)縮空(kong)氣的(de)(de)(de)作(zuo)用(yong)(yong)下(xia),使活塞往返沖(chong)擊(ji)(ji)鉆(zhan)頭,完(wan)成對巖(yan)石(shi)(shi)的(de)(de)(de)沖(chong)擊(ji)(ji);壓(ya)縮空(kong)氣從(cong)回(hui)轉(zhuan)供風機(ji)構進(jin)入,經中(zhong)空(kong)桿(gan)直達孔(kong)(kong)底,把(ba)破碎的(de)(de)(de)巖(yan)粉從(cong)鉆(zhan)桿(gan)與孔(kong)(kong)壁之間(jian)的(de)(de)(de)環形空(kong)間(jian)排至孔(kong)(kong)外(wai)。由此(ci)可(ke)見(jian),潛(qian)(qian)(qian)(qian)孔(kong)(kong)式鑿巖(yan)的(de)(de)(de)實質是(shi),在(zai)軸(zhou)向(xiang)(xiang)壓(ya)力(li)(li)的(de)(de)(de)作(zuo)用(yong)(yong)下(xia),沖(chong)擊(ji)(ji)和回(hui)轉(zhuan)兩(liang)種破碎巖(yan)石(shi)(shi)方(fang)法的(de)(de)(de)結合,其中(zhong)沖(chong)擊(ji)(ji)是(shi)間(jian)斷的(de)(de)(de),回(hui)轉(zhuan)是(shi)連(lian)續(xu)(xu)的(de)(de)(de),巖(yan)石(shi)(shi)在(zai)沖(chong)擊(ji)(ji)和剪(jian)(jian)切力(li)(li)作(zuo)用(yong)(yong)下(xia)不斷地被壓(ya)碎和剪(jian)(jian)碎。潛(qian)(qian)(qian)(qian)孔(kong)(kong)鑿巖(yan)中(zhong),起主導作(zuo)用(yong)(yong)的(de)(de)(de)是(shi)沖(chong)擊(ji)(ji)做功(gong)。
