一、電動葫蘆的組成結構

電動葫蘆結構(gou)緊湊，電(dian)機軸線(xian)(xian)垂直于卷筒軸線(xian)(xian)的電(dian)動(dong)葫(hu)蘆采用(yong)蝸輪傳動(dong)裝置(zhi)。其(qi)缺點為(wei)：長度尺寸大，寬度方面尺寸大，結構(gou)粗笨，機械效(xiao)率低，加工較難等(deng)。液壓(ya)(ya)系統為(wei)雙(shuang)重控制(zhi)(zhi)，溢流調(diao)節閥、磁接點壓(ya)(ya)力表均可對(dui)壓(ya)(ya)力進行(xing)精確(que)的控制(zhi)(zhi)。電(dian)器控制(zhi)(zhi)部門采用(yong)了(le)低電(dian)壓(ya)(ya)控制(zhi)(zhi)，增加了(le)支配系統的安全性。

起(qi)重量一般(ban)為 0.3～80噸，起(qi)升(sheng)高度為3～30米。由電(dian)動(dong)機(ji)、傳動(dong)機(ji)構和卷筒或鏈(lian)輪組(zu)成，分(fen)(fen)為鋼(gang)絲繩(sheng)電(dian)動(dong)葫(hu)蘆(lu)和環鏈(lian)電(dian)動(dong)葫(hu)蘆(lu)兩種。其中環鏈(lian)電(dian)動(dong)葫(hu)蘆(lu)分(fen)(fen)為進口和國產兩種；鋼(gang)絲繩(sheng)電(dian)動(dong)葫(hu)蘆(lu)分(fen)(fen)單(dan)速提(ti)(ti)(ti)升(sheng)、雙速提(ti)(ti)(ti)升(sheng)；微型電(dian)動(dong)葫(hu)蘆(lu)、卷揚機(ji)、多功能提(ti)(ti)(ti)升(sheng)機(ji)。

（二）安裝使用

電動(dong)葫(hu)蘆一(yi)般安裝在(zai)單梁(liang)起重機(ji)(ji)(ji)，橋式起重機(ji)(ji)(ji)，門式起重機(ji)(ji)(ji)，懸掛起重機(ji)(ji)(ji)上。稍加改(gai)造，還可以作卷揚機(ji)(ji)(ji)用。因此，它是提高勞動(dong)效率(lv)，改(gai)善勞動(dong)條件的必備機(ji)(ji)(ji)械。

（三）運行條件

環境溫度(du)：-20℃～+40℃

工作(zuo)制(zhi)度(du)：中級JC25%

重級：JC40%

當中級工(gong)作(zuo)制度電動(dong)葫(hu)蘆(lu)的(de)起(qi)重(zhong)量降低30%時，即為(wei)重(zhong)級工(gong)作(zuo)制度JC40%的(de)電動(dong)葫(hu)蘆(lu)。

重級工(gong)作制度JC40%的電動(dong)葫蘆是用在工(gong)作比較繁重，負載經常在額(e)定值或要(yao)求(qiu)安(an)全系數較高(gao)的情況下。

電動(dong)葫蘆(lu)結構減速器(qi)：采用三級定軸(zhou)(zhou)斜齒輪(lun)轉動(dong)機(ji)構，齒輪(lun)和齒輪(lun)軸(zhou)(zhou)用經過(guo)熱處理的合金鋼制成，箱(xiang)(xiang)體，箱(xiang)(xiang)蓋由(you)優(you)質鑄鐵制成，裝(zhuang)配嚴密，密封良好。減速器(qi)自成一個部(bu)件，裝(zhuang)卸極為方便。

控(kong)制箱：采用能在緊急情況下切斷(duan)主電(dian)路，并帶(dai)有(you)上下行程保(bao)護斷(duan)火限位器的裝(zhuang)置。確保(bao)了(le)電(dian)動葫(hu)蘆(lu)的安全運行。電(dian)器元件壽命長，使(shi)用可(ke)靠。

鋼絲繩(sheng)(sheng)：起重(zhong)鋼絲繩(sheng)(sheng)包括磷化涂層鋼絲繩(sheng)(sheng)、鍍(du)鋅鋼絲繩(sheng)(sheng)和不(bu)銹鋼絲繩(sheng)(sheng)，執行(xing)現行(xing)國家(jia)標準GB8918-2006重(zhong)要用(yong)途鋼絲繩(sheng)(sheng)，保證了經(jing)久(jiu)耐(nai)用(yong)。

錐形(xing)電動(dong)機：起升電機采用較大(da)起動(dong)力矩錐形(xing)轉子制動(dong)異步(bu)電動(dong)機，無須外加制動(dong)器。電機負載(zai)持續率為25%，電機采用B級或(huo)F級絕緣(yuan)，電機防護等(deng)級IP44/IP54。

按鈕開關：手(shou)操作(zuo)輕巧靈(ling)便(bian)，分(fen)有(you)繩(sheng)操縱和無線遙控兩(liang)種方式。

電動(dong)葫蘆的組(zu)成(cheng)部分有：電機、傳動(dong)機構、卷筒和鏈輪。

以電機和卷筒相(xiang)互位置不同大(da)致可(ke)分為四種類(lei)型：

1、電機軸線(xian)垂直于卷筒軸線(xian)的電動(dong)(dong)葫蘆采用蝸輪傳(chuan)動(dong)(dong)裝(zhuang)置(zhi)，寬度方面尺寸(cun)大， 結構笨重(zhong)， 機械效率低，加(jia)工較困(kun)難，已(yi)沒有(you)廠家生產這種(zhong)結構型式的產品了。

2、電(dian)動(dong)機軸線平行(xing)于卷筒軸線的電(dian)動(dong)葫(hu)蘆，其優點為高(gao)度與(yu)長(chang)度尺寸小。其缺點為寬度尺寸大，分組性(xing)、制造(zao)與(yu)裝配復雜(za)，軌道轉(zhuan)彎半徑大。

3、電(dian)機(ji)裝在卷(juan)筒里面的電(dian)動(dong)葫蘆(lu)，其優點為長(chang)度(du)尺寸小(xiao)，結構緊湊。其主要(yao)缺點為電(dian)機(ji)散熱條件差(cha)，分組性差(cha)，檢查、安裝、維護(hu)電(dian)機(ji)不便， 供電(dian)裝置復雜。

4、電機裝在(zai)卷筒外(wai)面的(de)電動葫蘆(lu)，其優點(dian)為分組(zu)性好、通(tong)用化程度高、改變起升(sheng)高度容(rong)易、安裝檢(jian)修方便。其缺點(dian)為長度尺寸大。
