起重機(ji)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)安裝在電動(dong)(dong)(dong)(dong)機(ji)的轉軸上，用來制(zhi)動(dong)(dong)(dong)(dong)電動(dong)(dong)(dong)(dong)機(ji)的運轉，使其(qi)運行或起升機(ji)構能夠準確可靠的停在預(yu)定的位置上。常(chang)用的有彈簧式短行程電磁鐵雙(shuang)(shuang)閘(zha)瓦(wa)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡(jian)稱(cheng)(cheng)短沖程制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)（單相制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)）；彈簧式長(chang)行程電磁鐵雙(shuang)(shuang)閘(zha)瓦(wa)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡(jian)稱(cheng)(cheng)長(chang)沖程制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)（三相制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)）；液(ye)壓(ya)推(tui)桿(gan)式雙(shuang)(shuang)閘(zha)瓦(wa)制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)，簡(jian)稱(cheng)(cheng)推(tui)桿(gan)式制(zhi)動(dong)(dong)(dong)(dong)器(qi)(qi)三種。

1、安裝操作情(qing)況不(bu)同，制(zhi)動器分為常閉式、常開式、綜合式三種類型。
起(qi)重機上多數采用常(chang)閉(bi)式制(zhi)(zhi)動(dong)(dong)器，常(chang)閉(bi)式制(zhi)(zhi)動(dong)(dong)器在機構(gou)(gou)不工(gong)作期間是閉(bi)合(he)的(de)。如(ru)果想要機構(gou)(gou)工(gong)作，只需要通過松(song)閘(zha)將制(zhi)(zhi)動(dong)(dong)器的(de)摩擦副分(fen)開，機構(gou)(gou)就可以運轉。

起重機制動(dong)裝置(zhi)的用途


制動裝置是保證起重機安(an)全正常工作的重要部件。
1、在吊運作業中，制(zhi)動裝置用以防止(zhi)懸(xuan)吊是物品或吊臂(bei)下落(luo)，防止(zhi)轉臺(tai)或者起重機(ji)在風力或者坡道分(fen)力作用下滑(hua)動。
2、使運轉著的機構降(jiang)低速度，0后停(ting)止運動。
3、也可以根據工(gong)作需要夾持重物運(yun)(yun)行。特(te)殊情(qing)況下(xia)，通過控制動力和(he)重力的平(ping)衡，調節運(yun)(yun)動速度(du)。


通(tong)用、電站、防暴、電動(dong)(dong)單(dan)梁、電動(dong)(dong)單(dan)梁懸(xuan)掛(gua)、電動(dong)(dong)葫(hu)蘆、冶(ye)金、絕緣起重(zhong)機起重(zhong)機制(zhi)動(dong)(dong)器(qi)(qi)根據(ju)驅(qu)動(dong)(dong)裝置的不同,可分為：短行(xing)程(cheng)電磁鐵(tie)(tie)制(zhi)動(dong)(dong)器(qi)(qi)、長(chang)行(xing)程(cheng)電磁鐵(tie)(tie)制(zhi)動(dong)(dong)器(qi)(qi)、液壓(ya)推桿瓦塊式制(zhi)動(dong)(dong)器(qi)(qi)和(he)液壓(ya)電磁鐵(tie)(tie)瓦塊式制(zhi)動(dong)(dong)器(qi)(qi)等.

　　起重機(ji)(ji)(ji)械的(de)安全規程(cheng)中規定：動(dong)(dong)(dong)(dong)(dong)(dong)力(li)驅動(dong)(dong)(dong)(dong)(dong)(dong)的(de)起重機(ji)(ji)(ji)，其起升、變幅、運行(xing)、旋轉機(ji)(ji)(ji)構都必須裝設制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器。制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器是利用(yong)磨擦(ca)原理(li)來實現機(ji)(ji)(ji)構制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)。制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器的(de)磨擦(ca)零件以一(yi)定的(de)作用(yong)力(li)壓緊機(ji)(ji)(ji)構中某一(yi)根上的(de)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)輪，產(chan)生制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)矩(ju)，利用(yong)這個制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)矩(ju)，使(shi)物體質量和(he)慣性(xing)力(li)產(chan)生的(de)力(li)矩(ju)減小，直至兩個力(li)矩(ju)平衡，達到調速或(huo)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)要求(qiu)。
　　起重機所用的制(zhi)動器是多種(zhong)多樣(yang)的。
　　按結(jie)構(gou)特性可分為：塊式、帶式和盤式三種，其中塊式用得0多(duo)。塊(kuai)式(shi)(shi)(shi)的按工(gong)作(zuo)狀(zhuang)態(tai)，可(ke)分為常(chang)閉(bi)式(shi)(shi)(shi)和常(chang)開式(shi)(shi)(shi)兩種。常(chang)閉(bi)式(shi)(shi)(shi)制動器(qi)經(jing)常(chang)處于合(he)閘狀(zhuang)態(tai)，當機(ji)構工(gong)作(zuo)時(shi)，可(ke)用電磁鐵或(huo)電力液壓(ya)推桿器(qi)等外(wai)力的作(zuo)用使之(zhi)松閘。常(chang)開式(shi)(shi)(shi)制動器(qi)與(yu)之(zhi)相反，它經(jing)常(chang)處于松閘狀(zhuang)態(tai)，只有施加外(wai)力時(shi)，才(cai)能(neng)使它合(he)閘。從(cong)工(gong)作(zuo)安全出發，起重機(ji)的各(ge)工(gong)作(zuo)機(ji)構都應采用常(chang)閉(bi)式(shi)(shi)(shi)制動器(qi)。
　　從(cong)工作狀態(tai)來看，0選常閉式，只有通電時才能(neng)松開(kai)工作，以(yi)免突然斷(duan)電重物(wu)自(zi)由下滑傷人。
　　
　　制動器的類型(xing)與結(jie)構
　　橋式(shi)起重機的(de)(de)常用的(de)(de)制(zhi)(zhi)動(dong)器(qi)(qi)(qi)有：短行程(cheng)電(dian)子塊(kuai)式(shi)制(zhi)(zhi)動(dong)器(qi)(qi)(qi)、長行程(cheng)瓦(wa)(wa)式(shi)制(zhi)(zhi)動(dong)器(qi)(qi)(qi)、液壓推桿瓦(wa)(wa)式(shi)制(zhi)(zhi)動(dong)器(qi)(qi)(qi)、液壓電(dian)磁瓦(wa)(wa)塊(kuai)式(shi)制(zhi)(zhi)動(dong)器(qi)(qi)(qi)等。
　　1、 塊式制動器
　　① 短行程(cheng)電(dian)子塊式制(zhi)動(dong)器：短行程(cheng)制(zhi)動(dong)器結構(gou)簡單、質量輕、制(zhi)動(dong)快。缺點是沖(chong)擊和噪(zao)聲0，壽命(ming)短，制動力(li)矩小(xiao)，有時有剩磁(ci)(ci)現象，只(zhi)適用(yong)于起升機構，無(wu)防爆(bao)型(xing)要(yao)(yao)用(yong)直(zhi)流電源(yuan)時需要(yao)(yao)更換電磁(ci)(ci)鐵。
　　② 長行(xing)程塊(kuai)式制(zhi)動器(qi)：這種(zhong)制(zhi)動器(qi)的優點(dian)是行(xing)程0，可(ke)以獲得較0的制動力矩，制動快(kuai)，很少有剩磁現(xian)象，比較(jiao)(jiao)安(an)全。缺(que)點是沖擊和噪聲(sheng)較(jiao)(jiao)0，壽命不夠長，構件(jian)多且(qie)復(fu)雜，體積和質量0，效率低，只適用于起升機構。
　　③ 電(dian)力液壓(ya)塊式(shi)制動(dong)器：用(yong)(yong)液壓(ya)電(dian)磁塊替代長行(xing)程塊式(shi)制動(dong)器電(dian)磁鐵，有YWZ（液壓(ya)推桿）和(he)YDWZ（液壓(ya)電(dian)磁鐵）兩種。YWZ型(xing)(xing)制動(dong)平穩(wen)，無噪聲、體積小，用(yong)(yong)于運行(xing)機(ji)構(gou)(gou)和(he)回轉機(ji)構(gou)(gou)較(jiao)好(hao)。因其(qi)制停動(dong)作較(jiao)慢，不(bu)適(shi)宜(yi)起升機(ji)構(gou)(gou)使用(yong)(yong)，以防溜鉤(gou)。YDWZ型(xing)(xing)各種性能都(dou)較(jiao)好(hao)，而(er)且(qie)不(bu)需經常調整，只需直流電(dian)源即可。
　　2、 帶式制動(dong)器(qi)：在(zai)外(wai)形尺寸受0制，制動(dong)轉(zhuan)矩要求很0的(de)場合，可考慮選(xuan)用帶式(shi)制(zhi)動器，流動式(shi)起重(zhong)(zhong)機(ji)上多(duo)采用這種(zhong)制(zhi)動裝置。帶式(shi)制(zhi)動器的(de)缺點是安全(quan)性較低，制(zhi)動帶斷裂將造成(cheng)嚴重(zhong)(zhong)后果。
　　3、 盤式(shi)制動(dong)器(qi)：盤式(shi)制動(dong)器(qi)制動(dong)轉距0，外形尺(chi)寸小，磨擦(ca)面積0，磨損小，應用(yong)日(ri)益廣泛。盤式制動器的缺點：主要是電磁鐵線圈溫升(sheng)高(gao)易(yi)發熱、沖擊、噪聲0和零部件易損壞。
　　4、錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi) 錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)制(zhi)(zhi)動(dong)(dong)(dong)(dong)環與制(zhi)(zhi)動(dong)(dong)(dong)(dong)輪均為錐(zhui)(zhui)形(xing)(xing)，錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)是(shi)錐(zhui)(zhui)形(xing)(xing)電(dian)(dian)動(dong)(dong)(dong)(dong)機的(de)一(yi)部(bu)分，錐(zhui)(zhui)形(xing)(xing)電(dian)(dian)動(dong)(dong)(dong)(dong)機之所以把轉子、定子設計制(zhi)(zhi)作成(cheng)錐(zhui)(zhui)形(xing)(xing)，其(qi)目的(de)就是(shi)為了獲得一(yi)個結構簡單輕巧，制(zhi)(zhi)作裝配調整方便，并與電(dian)(dian)動(dong)(dong)(dong)(dong)機不可分割(ge)的(de)一(yi)種錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)，錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)目前被(bei)電(dian)(dian)動(dong)(dong)(dong)(dong)葫(hu)蘆廣泛(fan)采用，CD、AS、DH型電(dian)(dian)動(dong)(dong)(dong)(dong)葫(hu)蘆均采用錐(zhui)(zhui)形(xing)(xing)制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)。
