主要是用(yong)來對已有的(de)傳(chuan)(chuan)統(tong)(tong)閘(zha)門進(jin)行(xing)改造，在不動(dong)(dong)(dong)閘(zha)門基礎設施及(ji)閘(zha)板的(de)前提下，可以(yi)更(geng)換啟閉機和控制系統(tong)(tong)來完成改造，進(jin)而(er)(er)使閘(zha)門實(shi)現自(zi)動(dong)(dong)(dong)化、智能化。該(gai)分體式閘(zha)門核心部分是采(cai)用(yong)了斜齒圓柱齒輪傳(chuan)(chuan)動(dong)(dong)(dong)方(fang)案，該(gai)方(fang)案相比傳(chuan)(chuan)統(tong)(tong)渦輪蝸桿減(jian)速機而(er)(er)言，有更(geng)高的(de)傳(chuan)(chuan)動(dong)(dong)(dong)效率，運行(xing)更(geng)加平穩，且(qie)可靠性高。
