一、電動葫蘆的組成結構

電動葫蘆結構緊湊，電機軸線垂直于卷筒軸線的(de)電動葫蘆采用蝸(gua)輪傳(chuan)動裝置。其(qi)缺點為：長度(du)尺寸大，寬度(du)方面尺寸大，結構粗(cu)笨(ben)，機械效率低(di)，加工較難(nan)等。液(ye)壓(ya)(ya)系(xi)統為雙重控(kong)(kong)制(zhi)(zhi)，溢(yi)流(liu)調節(jie)閥、磁接點壓(ya)(ya)力表均(jun)可對壓(ya)(ya)力進行精確的(de)控(kong)(kong)制(zhi)(zhi)。電器控(kong)(kong)制(zhi)(zhi)部門采用了低(di)電壓(ya)(ya)控(kong)(kong)制(zhi)(zhi)，增加了支(zhi)配(pei)系(xi)統的(de)安(an)全性。

起重量一般(ban)為(wei)(wei)(wei) 0.3～80噸，起升(sheng)高度為(wei)(wei)(wei)3～30米。由電(dian)動(dong)(dong)(dong)機、傳動(dong)(dong)(dong)機構(gou)和卷(juan)筒或鏈(lian)輪組(zu)成，分為(wei)(wei)(wei)鋼絲繩電(dian)動(dong)(dong)(dong)葫(hu)(hu)蘆(lu)和環鏈(lian)電(dian)動(dong)(dong)(dong)葫(hu)(hu)蘆(lu)兩(liang)種(zhong)。其中環鏈(lian)電(dian)動(dong)(dong)(dong)葫(hu)(hu)蘆(lu)分為(wei)(wei)(wei)進(jin)口和國產兩(liang)種(zhong)；鋼絲繩電(dian)動(dong)(dong)(dong)葫(hu)(hu)蘆(lu)分單(dan)速提升(sheng)、雙速提升(sheng)；微(wei)型電(dian)動(dong)(dong)(dong)葫(hu)(hu)蘆(lu)、卷(juan)揚機、多功能(neng)提升(sheng)機。

（二）安裝使用

電動(dong)葫蘆一(yi)般安裝在(zai)單梁起重(zhong)(zhong)(zhong)機(ji)，橋式起重(zhong)(zhong)(zhong)機(ji)，門式起重(zhong)(zhong)(zhong)機(ji)，懸掛起重(zhong)(zhong)(zhong)機(ji)上。稍加改造，還可以作卷(juan)揚機(ji)用。因此(ci)，它是(shi)提(ti)高勞動(dong)效率，改善勞動(dong)條(tiao)件的必備機(ji)械。

（三）運行條件

環境溫(wen)度(du)：-20℃～+40℃

工作(zuo)制(zhi)度(du)：中級JC25%

重級：JC40%

當(dang)中級(ji)(ji)工(gong)作制度(du)電動(dong)葫蘆的起重量降低30%時(shi)，即為(wei)重級(ji)(ji)工(gong)作制度(du)JC40%的電動(dong)葫蘆。

重(zhong)級工作(zuo)制度JC40%的電動葫蘆是(shi)用(yong)在(zai)工作(zuo)比較(jiao)繁重(zhong)，負載經常在(zai)額定值或要(yao)求安全(quan)系數(shu)較(jiao)高的情況下。

電動(dong)葫蘆結(jie)構(gou)(gou)減(jian)(jian)速器：采用三級定軸(zhou)斜齒輪(lun)轉動(dong)機構(gou)(gou)，齒輪(lun)和齒輪(lun)軸(zhou)用經過熱處(chu)理的合金(jin)鋼制成，箱體，箱蓋由優質鑄鐵制成，裝(zhuang)(zhuang)配(pei)嚴密(mi)，密(mi)封(feng)良好(hao)。減(jian)(jian)速器自成一個(ge)部件，裝(zhuang)(zhuang)卸極為(wei)方便。

控制(zhi)箱：采用能在緊急情況下切斷主電(dian)路，并帶有上下行程保護斷火限位(wei)器的裝置。確(que)保了電(dian)動葫蘆的安全(quan)運行。電(dian)器元件壽命長，使用可靠。

鋼(gang)(gang)絲(si)(si)繩(sheng)：起重(zhong)鋼(gang)(gang)絲(si)(si)繩(sheng)包括磷化涂層鋼(gang)(gang)絲(si)(si)繩(sheng)、鍍(du)鋅鋼(gang)(gang)絲(si)(si)繩(sheng)和不銹(xiu)鋼(gang)(gang)絲(si)(si)繩(sheng)，執行(xing)現行(xing)國家標(biao)準GB8918-2006重(zhong)要用途鋼(gang)(gang)絲(si)(si)繩(sheng)，保證了經久(jiu)耐用。

錐形電(dian)動(dong)(dong)(dong)機：起(qi)升電(dian)機采用較大起(qi)動(dong)(dong)(dong)力矩錐形轉子制動(dong)(dong)(dong)異步電(dian)動(dong)(dong)(dong)機，無(wu)須外加制動(dong)(dong)(dong)器。電(dian)機負載持續率為(wei)25%，電(dian)機采用B級或F級絕緣，電(dian)機防護等級IP44/IP54。

按(an)鈕開關：手操(cao)作(zuo)輕巧(qiao)靈便，分(fen)有繩操(cao)縱和(he)無線遙控兩種方式。

電動葫蘆的組成部分有：電機(ji)(ji)、傳動機(ji)(ji)構、卷(juan)筒和鏈(lian)輪。

以電機和卷筒相(xiang)互(hu)位置不同大(da)致可分為四種(zhong)類型：

1、電機(ji)軸(zhou)線垂(chui)直于卷(juan)筒軸(zhou)線的(de)電動葫蘆(lu)采用蝸輪傳動裝置，寬度方面尺寸大， 結(jie)構(gou)笨重， 機(ji)械(xie)效率低(di)，加工較困(kun)難，已沒有廠家生產這種結(jie)構(gou)型式的(de)產品(pin)了。

2、電動(dong)(dong)機軸(zhou)線(xian)(xian)平行(xing)于卷筒(tong)軸(zhou)線(xian)(xian)的電動(dong)(dong)葫(hu)蘆，其優點(dian)(dian)為(wei)(wei)高度(du)與長(chang)度(du)尺(chi)(chi)寸小。其缺點(dian)(dian)為(wei)(wei)寬度(du)尺(chi)(chi)寸大(da)，分組性、制造與裝配復雜，軌(gui)道轉彎半徑大(da)。

3、電機(ji)(ji)裝(zhuang)在卷筒里面的電動葫蘆，其優點為(wei)長度尺寸小，結構緊湊。其主(zhu)要缺點為(wei)電機(ji)(ji)散(san)熱(re)條件(jian)差(cha)，分(fen)組性(xing)差(cha)，檢(jian)查、安裝(zhuang)、維護電機(ji)(ji)不便(bian)， 供(gong)電裝(zhuang)置復雜。

4、電機(ji)裝在卷(juan)筒(tong)外面的電動葫蘆(lu)，其(qi)優點為分組性好、通用化程度高、改(gai)變(bian)起(qi)升高度容易、安裝檢修方(fang)便(bian)。其(qi)缺點為長(chang)度尺寸大。
