提升容器(qi)的(de)承(cheng)接(jie)(jie)(jie)是(shi)礦井提升中的(de)重要(yao)(yao)環節，特別是(shi)下井口承(cheng)接(jie)(jie)(jie)因環境差、載荷變化大(da)，使其一(yi)直(zhi)成為困擾礦井生(sheng)產及事(shi)故(gu)多發部位(wei)。目前，下井口承(cheng)接(jie)(jie)(jie)方法主要(yao)(yao)有(you)(you)承(cheng)接(jie)(jie)(jie)梁(liang)(liang)、罐座(zuo)和(he)搖(yao)臺(tai)(tai)三種。其中承(cheng)接(jie)(jie)(jie)梁(liang)(liang)和(he)罐座(zuo)因易(yi)發生(sheng)蹾(dun)罐事(shi)故(gu)而被禁止使用。搖(yao)臺(tai)(tai)雖不易(yi)發生(sheng)蹾(dun)罐事(shi)故(gu)，但(dan)有(you)(you)操作復雜、裝卸效率低、故(gu)障率高及能耗大(da)等不足。THT型罐籠安(an)全(quan)承(cheng)接(jie)(jie)(jie)裝置（井底(di)自補償托罐搖(yao)臺(tai)(tai)）集搖(yao)臺(tai)(tai)和(he)罐座(zuo)的(de)優點于(yu)一(yi)身，承(cheng)接(jie)(jie)(jie)時即能準確(que)對罐和(he)穩罐，又能在承(cheng)接(jie)(jie)(jie)過程中具有(you)(you)緩沖及避免蹾(dun)罐事(shi)故(gu)發生(sheng)的(de)安(an)全(quan)保護(hu)功能。 　　

特點(dian)：具有(you)定點(dian)承接穩罐(guan)功(gong)能，不需對(dui)罐(guan)，井口罐(guan)籠(long)上下同時裝車(che)提高(gao)效率明顯；具有(you)過(guo)放(fang)保護功(gong)能；使(shi)用及維護簡單(dan)方便(bian)，減輕人(ren)工勞動強度，降低提升能耗：過(guo)放(fang)機構(gou)動作后可(ke)自(zi)動復(fu)位。 　　

結構(gou)(gou)(gou)與原(yuan)理：該裝置(zhi)(zhi)(zhi)主(zhu)要(yao)由托(tuo)(tuo)(tuo)爪(zhua)、彈簧緩沖(chong)桿(gan)(含保護件(jian))、轉換(huan)機(ji)(ji)構(gou)(gou)(gou)、機(ji)(ji)架等部件(jian)組(zu)成。彈簧緩沖(chong)桿(gan)按(an)載(zai)荷及安全保護需(xu)要(yao)調(diao)好預緊力(li)(限(xian)力(li))。承接(jie)(jie)罐(guan)(guan)(guan)籠(long)(long)(long)時(shi)，將裝置(zhi)(zhi)(zhi)轉換(huan)機(ji)(ji)構(gou)(gou)(gou)置(zhi)(zhi)(zhi)于承接(jie)(jie)位(wei)置(zhi)(zhi)(zhi)使托(tuo)(tuo)(tuo)爪(zhua)伸(shen)出(chu)，當(dang)罐(guan)(guan)(guan)籠(long)(long)(long)以正(zheng)常爬行(xing)速度到(dao)達承接(jie)(jie)位(wei)置(zhi)(zhi)(zhi)時(shi)，托(tuo)(tuo)(tuo)爪(zhua)托(tuo)(tuo)(tuo)住罐(guan)(guan)(guan)籠(long)(long)(long)并(bing)通過(guo)彈簧緩沖(chong)桿(gan)吸收(shou)罐(guan)(guan)(guan)籠(long)(long)(long)動(dong)能后將罐(guan)(guan)(guan)籠(long)(long)(long)準確置(zhi)(zhi)(zhi)于裝卸位(wei)罩，罐(guan)(guan)(guan)內外軌(gui)道準確對位(wei)使進(jin)出(chu)車順暢(chang)；反之，一(yi)旦過(guo)放時(shi)，因罐(guan)(guan)(guan)籠(long)(long)(long)動(dong)能過(guo)大，緩沖(chong)行(xing)程(cheng)超出(chu)預定緩沖(chong)行(xing)程(cheng)時(shi)(一(yi)般50～150mm)，保護機(ji)(ji)構(gou)(gou)(gou)立(li)即動(dong)作使托(tuo)(tuo)(tuo)爪(zhua)放過(guo)罐(guan)(guan)(guan)籠(long)(long)(long)避免蹾罐(guan)(guan)(guan)(任何情(qing)況下較大緩沖(chong)減(jian)速度小于5g)。此外，為方便檢修或升降特(te)殊材料等需(xu)要(yao)，轉換(huan)機(ji)(ji)構(gou)(gou)(gou)可在(zai)不需(xu)承接(jie)(jie)時(shi)將托(tuo)(tuo)(tuo)爪(zhua)收(shou)回使罐(guan)(guan)(guan)籠(long)(long)(long)自(zi)由通過(guo)。
