起(qi)重機(ji)(ji)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)安裝在電動(dong)(dong)(dong)(dong)機(ji)(ji)的(de)轉軸上，用來制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)電動(dong)(dong)(dong)(dong)機(ji)(ji)的(de)運轉，使(shi)其運行或起(qi)升機(ji)(ji)構(gou)能夠準確可(ke)靠(kao)的(de)停(ting)在預(yu)定的(de)位置上。常用的(de)有彈簧(huang)式短行程(cheng)(cheng)電磁鐵雙(shuang)閘瓦制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡稱短沖(chong)程(cheng)(cheng)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)（單(dan)相(xiang)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)）；彈簧(huang)式長(chang)行程(cheng)(cheng)電磁鐵雙(shuang)閘瓦制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡稱長(chang)沖(chong)程(cheng)(cheng)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)（三(san)相(xiang)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)）；液(ye)壓推桿(gan)式雙(shuang)閘瓦制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡稱推桿(gan)式制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)三(san)種。

抱閘(zha)是(shi)橋(qiao)式(shi)起重機(ji)的制動器，還有防撞0位器。

1、安裝(zhuang)操作情況不同，制動器分(fen)為常(chang)(chang)閉式、常(chang)(chang)開式、綜合式三種類型。
起重機(ji)上多數采用常閉式(shi)制動(dong)器，常閉式(shi)制動(dong)器在(zai)機(ji)構(gou)不工(gong)作期間是閉合的。如(ru)果想要機(ji)構(gou)工(gong)作，只需(xu)要通過松閘將制動(dong)器的摩擦副(fu)分開，機(ji)構(gou)就可以運(yun)轉。
2、按其造(zao)型來分，有塊(kuai)式(shi)(shi)制動(dong)器(qi)、帶式(shi)(shi)制動(dong)器(qi)、盤(pan)式(shi)(shi)制動(dong)器(qi)和圓錐式(shi)(shi)制動(dong)器(qi)等。

起(qi)重機制動裝置的用途


制動裝置是保證起(qi)重(zhong)機(ji)安全正常工作的重(zhong)要部件。
1、在(zai)吊運作業(ye)中，制動裝置用以(yi)防止懸吊是(shi)物品或吊臂下落，防止轉臺或者起重機在(zai)風(feng)力或者坡道(dao)分(fen)力作用下滑動。
2、使運轉著的機(ji)構(gou)降低速度(du)，0后停止運動。
3、也(ye)可以(yi)根據工作需要夾持(chi)重物運行。特殊(shu)情況下，通(tong)過(guo)控制動力(li)和重力(li)的平衡，調節(jie)運動速度。


通用、電(dian)站、防(fang)暴、電(dian)動(dong)(dong)(dong)(dong)單(dan)(dan)梁、電(dian)動(dong)(dong)(dong)(dong)單(dan)(dan)梁懸(xuan)掛、電(dian)動(dong)(dong)(dong)(dong)葫蘆、冶金、絕緣起重(zhong)機(ji)起重(zhong)機(ji)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)根據(ju)驅動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)不同,可分為：短行(xing)(xing)程電(dian)磁鐵(tie)(tie)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)、長行(xing)(xing)程電(dian)磁鐵(tie)(tie)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)、液(ye)壓(ya)推桿瓦(wa)塊式制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)和液(ye)壓(ya)電(dian)磁鐵(tie)(tie)瓦(wa)塊式制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)等.

　　起重機(ji)(ji)械的(de)(de)(de)安全規程中規定：動(dong)力(li)驅動(dong)的(de)(de)(de)起重機(ji)(ji)，其起升、變幅(fu)、運行、旋轉機(ji)(ji)構(gou)都必須(xu)裝設制動(dong)器。制動(dong)器是(shi)利(li)用磨擦(ca)原理來實現機(ji)(ji)構(gou)制動(dong)的(de)(de)(de)。制動(dong)器的(de)(de)(de)磨擦(ca)零件以(yi)一定的(de)(de)(de)作(zuo)用力(li)壓(ya)緊機(ji)(ji)構(gou)中某(mou)一根(gen)上(shang)的(de)(de)(de)制動(dong)輪，產生制動(dong)力(li)矩(ju)，利(li)用這個制動(dong)力(li)矩(ju)，使物體質量和慣性(xing)力(li)產生的(de)(de)(de)力(li)矩(ju)減小，直(zhi)至兩個力(li)矩(ju)平衡，達到(dao)調速或制動(dong)的(de)(de)(de)要求(qiu)。
　　起重機所用的(de)制動(dong)器是多種多樣的(de)。
　　按結構(gou)特性可分(fen)為：塊式、帶式和(he)盤式三(san)種，其中塊式用得0多。塊式(shi)(shi)的按工(gong)作(zuo)(zuo)狀態，可分(fen)為常(chang)(chang)(chang)閉(bi)式(shi)(shi)和常(chang)(chang)(chang)開(kai)(kai)式(shi)(shi)兩種。常(chang)(chang)(chang)閉(bi)式(shi)(shi)制(zhi)動器(qi)經常(chang)(chang)(chang)處于合閘(zha)狀態，當(dang)機構工(gong)作(zuo)(zuo)時，可用(yong)電(dian)磁(ci)鐵或電(dian)力(li)液壓推桿器(qi)等外力(li)的作(zuo)(zuo)用(yong)使之(zhi)松(song)閘(zha)。常(chang)(chang)(chang)開(kai)(kai)式(shi)(shi)制(zhi)動器(qi)與之(zhi)相反，它經常(chang)(chang)(chang)處于松(song)閘(zha)狀態，只有施加外力(li)時，才能(neng)使它合閘(zha)。從工(gong)作(zuo)(zuo)安全出(chu)發(fa)，起重機的各工(gong)作(zuo)(zuo)機構都應采用(yong)常(chang)(chang)(chang)閉(bi)式(shi)(shi)制(zhi)動器(qi)。
　　從工作狀態(tai)來看(kan)，0選(xuan)常(chang)閉式，只有(you)通電時才能(neng)松開工作(zuo)，以免(mian)突然斷電重(zhong)物自由下滑(hua)傷人。
　　
　　制動器的類型與結構
　　橋式(shi)起(qi)重機的常用的制(zhi)動器(qi)有：短行程電(dian)子塊式(shi)制(zhi)動器(qi)、長(chang)行程瓦式(shi)制(zhi)動器(qi)、液壓推桿瓦式(shi)制(zhi)動器(qi)、液壓電(dian)磁(ci)瓦塊式(shi)制(zhi)動器(qi)等。
　　1、 塊(kuai)式制(zhi)動器(qi)
　　① 短行(xing)程電子塊式制(zhi)動(dong)(dong)器：短行(xing)程制(zhi)動(dong)(dong)器結(jie)構(gou)簡單、質量輕、制(zhi)動(dong)(dong)快。缺點是沖擊和噪聲0，壽命短，制動力矩小，有時有剩磁現(xian)象(xiang)，只適(shi)用(yong)于起(qi)升機構，無防爆(bao)型要(yao)用(yong)直流電(dian)源時需(xu)要(yao)更換(huan)電(dian)磁鐵(tie)。
　　② 長行程(cheng)塊式制(zhi)動器：這種制(zhi)動器的優(you)點(dian)是行程(cheng)0，可以獲(huo)得(de)較0的制動(dong)(dong)力矩，制動(dong)(dong)快，很少有剩磁現象，比較(jiao)安全。缺點是(shi)沖擊和噪(zao)聲較(jiao)0，壽(shou)命不夠長，構件多且復雜，體積和質量0，效率低，只適用于起升機構。
　　③ 電(dian)力液(ye)壓塊(kuai)式制動(dong)(dong)器(qi)：用液(ye)壓電(dian)磁塊(kuai)替(ti)代長(chang)行程塊(kuai)式制動(dong)(dong)器(qi)電(dian)磁鐵，有YWZ（液(ye)壓推桿(gan)）和YDWZ（液(ye)壓電(dian)磁鐵）兩種。YWZ型(xing)制動(dong)(dong)平穩，無(wu)噪聲(sheng)、體積小(xiao)，用于運(yun)行機(ji)(ji)構和回(hui)轉機(ji)(ji)構較好。因其制停動(dong)(dong)作較慢，不適宜起升(sheng)機(ji)(ji)構使用，以(yi)防溜(liu)鉤。YDWZ型(xing)各(ge)種性能(neng)都較好，而且不需經常調整，只需直流電(dian)源(yuan)即可(ke)。
　　2、 帶式制動器：在外形尺(chi)寸受0制(zhi)，制(zhi)動(dong)轉矩要求(qiu)很0的場合，可考慮選用帶式(shi)制(zhi)動(dong)(dong)器(qi)，流動(dong)(dong)式(shi)起重(zhong)機(ji)上多(duo)采用這種制(zhi)動(dong)(dong)裝置。帶式(shi)制(zhi)動(dong)(dong)器(qi)的缺點是安全性較低，制(zhi)動(dong)(dong)帶斷裂(lie)將造成嚴重(zhong)后(hou)果。
　　3、 盤(pan)式(shi)(shi)制動(dong)器：盤(pan)式(shi)(shi)制動(dong)器制動(dong)轉距(ju)0，外形尺(chi)寸小，磨擦面積0，磨(mo)損小(xiao)，應用日益廣泛。盤式制動(dong)器的缺點：主要是電磁鐵線圈溫(wen)升高易發熱、沖(chong)擊、噪(zao)聲0和(he)零部件(jian)易損壞(huai)。
　　4、錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi) 錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)的制(zhi)(zhi)動(dong)(dong)(dong)環與制(zhi)(zhi)動(dong)(dong)(dong)輪均為錐(zhui)(zhui)(zhui)形(xing)，錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)是(shi)錐(zhui)(zhui)(zhui)形(xing)電動(dong)(dong)(dong)機的一(yi)部分，錐(zhui)(zhui)(zhui)形(xing)電動(dong)(dong)(dong)機之所以把轉子(zi)(zi)、定子(zi)(zi)設計制(zhi)(zhi)作成錐(zhui)(zhui)(zhui)形(xing)，其目的就是(shi)為了獲得一(yi)個結(jie)構簡單輕(qing)巧，制(zhi)(zhi)作裝配(pei)調整方(fang)便，并與電動(dong)(dong)(dong)機不(bu)可分割(ge)的一(yi)種錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)，錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)目前被電動(dong)(dong)(dong)葫(hu)蘆廣泛采(cai)用，CD、AS、DH型電動(dong)(dong)(dong)葫(hu)蘆均采(cai)用錐(zhui)(zhui)(zhui)形(xing)制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)。
