輸送機的制動裝置有兩個功能：一是正常停機，即當輸送機在空載或滿載條件下停機時，可以可靠地制動輸送設備；二是緊急停機，即當輸送機工作異常或發生緊急事故（如輸送帶撕裂或運行偏差等故障）時，對輸送設備進行緊急制動，快速制動。
制(zhi)動(dong)(dong)裝置(zhi)根據(ju)(ju)工作性質(zhi)分(fen)為制(zhi)動(dong)(dong)器和逆止器。前者(zhe)(zhe)用于(yu)停(ting)(ting)止輸(shu)(shu)送機(ji)(ji)，后者(zhe)(zhe)用于(yu)運(yun)輸(shu)(shu)輸(shu)(shu)送機(ji)(ji)，以防止其在停(ting)(ting)機(ji)(ji)時(shi)反轉。制(zhi)動(dong)(dong)裝置(zhi)的選擇應根據(ju)(ju)輸(shu)(shu)送機(ji)(ji)的具體使用條件確定。如果水(shui)平(ping)運(yun)輸(shu)(shu)需要準確停(ting)(ting)車或緊急(ji)制(zhi)動(dong)(dong)，應安裝制(zhi)動(dong)(dong)器。下面(mian)中輸(shu)(shu)的小編就跟(gen)大家聊一聊制(zhi)動(dong)(dong)裝置(zhi)中的制(zhi)動(dong)(dong)器。
電(dian)磁(ci)(ci)閘(zha)瓦制(zhi)(zhi)動(dong)(dong)器是一種常閉制(zhi)(zhi)動(dong)(dong)器。它依靠與固定(ding)支架連接(jie)的(de)制(zhi)(zhi)動(dong)(dong)塊(kuai)來壓縮傳(chuan)動(dong)(dong)軸(zhou)上的(de)制(zhi)(zhi)動(dong)(dong)輪，并通過制(zhi)(zhi)動(dong)(dong)塊(kuai)與制(zhi)(zhi)動(dong)(dong)輪之間的(de)摩(mo)擦產生制(zhi)(zhi)動(dong)(dong)扭矩。它通過電(dian)磁(ci)(ci)鐵(tie)的(de)吸入和釋放來控制(zhi)(zhi)制(zhi)(zhi)動(dong)(dong)器的(de)松動(dong)(dong)和鎖(suo)定(ding)。由于電(dian)磁(ci)(ci)鐵(tie)斷電(dian)時吸力突然消失，壓縮彈簧(huang)突然增強，會對機(ji)構產生劇烈制(zhi)(zhi)動(dong)(dong)，導(dao)致傳(chuan)動(dong)(dong)機(ji)構機(ji)械(xie)振動(dong)(dong)，電(dian)磁(ci)(ci)鐵(tie)使用(yong)壽命短。這種制(zhi)(zhi)動(dong)(dong)器主要用(yong)于水平或傾斜(xie)小的(de)帶式(shi)輸送機(ji)。
電(dian)動(dong)(dong)液(ye)(ye)壓(ya)(ya)推(tui)(tui)桿制動(dong)(dong)器(qi)(qi)(qi)(qi)，這種制動(dong)(dong)器(qi)(qi)(qi)(qi)可(ke)用于水(shui)平，向上(shang)、向下運輸的(de)(de)輸送機(ji)，但制動(dong)(dong)扭(niu)矩(ju)很小，安裝在減速器(qi)(qi)(qi)(qi)的(de)(de)一個或兩個軸上(shang)。制動(dong)(dong)器(qi)(qi)(qi)(qi)通電(dian)后(hou)，電(dian)動(dong)(dong)液(ye)(ye)壓(ya)(ya)推(tui)(tui)動(dong)(dong)器(qi)(qi)(qi)(qi)推(tui)(tui)動(dong)(dong)制動(dong)(dong)桿松開制動(dong)(dong)器(qi)(qi)(qi)(qi)。當電(dian)力損失時，制動(dong)(dong)力由彈(dan)簧(huang)和(he)杠桿添加(jia)到制動(dong)(dong)瓦(wa)上(shang)。根據電(dian)動(dong)(dong)液(ye)(ye)壓(ya)(ya)推(tui)(tui)動(dong)(dong)器(qi)(qi)(qi)(qi)的(de)(de)結(jie)構原理(li)，傳(chuan)動(dong)(dong)軸7和(he)固定在傳(chuan)動(dong)(dong)軸上(shang)的(de)(de)葉(xie)輪(lun)(lun)6與(yu)電(dian)機(ji)8一起(qi)高速旋轉，將液(ye)(ye)壓(ya)(ya)缸(gang)3中(zhong)活(huo)(huo)塞(sai)5上(shang)部(bu)的(de)(de)油吸入活(huo)(huo)塞(sai)和(he)葉(xie)輪(lun)(lun)下部(bu)，形成(cheng)壓(ya)(ya)差，迫使(shi)活(huo)(huo)塞(sai)和(he)固定在活(huo)(huo)塞(sai)上(shang)的(de)(de)推(tui)(tui)桿4與(yu)傳(chuan)動(dong)(dong)軸和(he)葉(xie)輪(lun)(lun)一起(qi)上(shang)升(sheng)，提升(sheng)制動(dong)(dong)桿；斷電(dian)后(hou)，推(tui)(tui)桿在制動(dong)(dong)彈(dan)簧(huang)的(de)(de)作用下復位。葉(xie)輪(lun)(lun)和(he)活(huo)(huo)塞(sai)下部(bu)的(de)(de)油通過葉(xie)輪(lun)(lun)徑向葉(xie)片之間的(de)(de)流(liu)動(dong)(dong)通道再次壓(ya)(ya)到活(huo)(huo)塞(sai)上(shang)部(bu)。
盤式制動器是一種常閉制動裝置，通過松開油壓和加載彈簧來產生制動力矩。它有很大的制動力矩、可調、動作靈敏、散熱性能好、使用和維護方便；缺點是需要設置油泵站，所以體積大。為了防止制動過程中的高溫，已經開發出了自冷盤式制動裝置。其結構特點是制動盤做成空心葉片，工作時會產生循環風流，從而提高散熱性能。這種制動器主要用于大型帶式輸送機和水平輸送機、向上、可以采用向下運輸。
