防爆(bao)鋼(gang)絲(si)(si)繩(sheng)電動葫蘆具有結構(gou)緊湊、自(zi)重(zhong)輕、體積小、起重(zhong)能力大(da)。當廠房內(nei)充(chong)有爆(bao)炸性混合物時(shi)，在保(bao)證安全的前提下是改善勞動條件，提高勞動生產率的有力工(gong)具，因而成為合理工(gong)藝過程中必備的機(ji)械設備。防爆(bao)鋼(gang)絲(si)(si)繩(sheng)電動葫蘆主要(yao)組件構(gou)造特征：
減速器：為(wei)三級(ji)圓柱齒輪減速器，齒輪及軸的材質均選用優質合(he)金(jin)鋼，并(bing)精(jing)工(gong)制造，全部裝以滾(gun)動軸承。外殼(ke)為(wei)優質鑄(zhu)鐵，加工(gong)中心加工(gong)，裝配嚴密，灰(hui)塵(chen)不易侵入。
卷揚裝(zhuang)置(zhi)：卷筒為鑄鐵或厚(hou)壁(bi)無縫鋼管(guan)制成，置(zhi)于(yu)鋼制外(wai)殼內(nei)并以花鍵孔與(yu)減(jian)速器連接(jie)，另一(yi)端則以滾動(dong)軸承與(yu)電動(dong)機端蓋連接(jie)。外(wai)殼以鋼板(ban)(ban)卷制。鋼絲繩(sheng)(sheng)按照(zhao)卷筒上螺紋(wen)槽纏繞，采用(yong)導(dao)(dao)繩(sheng)(sheng)器排繩(sheng)(sheng)，并通過停(ting)止塊驅動(dong)斷火限(xian)位開關，保證吊(diao)鉤到達(da)上下極限(xian)位置(zhi)時，及(ji)時切斷起(qi)升電動(dong)機電源；繩(sheng)(sheng)端使用(yong)壓繩(sheng)(sheng)板(ban)(ban)，通過螺栓緊固于(yu)卷筒上，拆(chai)換(huan)鋼絲繩(sheng)(sheng)時，只(zhi)須將導(dao)(dao)繩(sheng)(sheng)器拆(chai)除(chu)，無須拆(chai)除(chu)外(wai)殼，維修方便。
運(yun)(yun)行(xing)機(ji)構(gou)(gou)：本(ben)系(xi)列防爆電動(dong)(dong)葫蘆(lu)的運(yun)(yun)行(xing)機(ji)構(gou)(gou)，采(cai)用(yong)電動(dong)(dong)小車，其減速器齒(chi)輪位優(you)質鋼(gang)鍛制，并經(jing)熱處理，全部采(cai)用(yong)滾動(dong)(dong)軸(zhou)承(cheng)，在大起升高度(du)時，運(yun)(yun)行(xing)機(ji)構(gou)(gou)與(yu)起升起構(gou)(gou)采(cai)用(yong)關節軸(zhou)承(cheng)連接(jie)，保證運(yun)(yun)行(xing)靈活，回轉半徑小，使用(yong)方便，壽命長(chang)，運(yun)(yun)行(xing)機(ji)構(gou)(gou)所適(shi)用(yong)的工字(zi)鋼(gang)軌道應按(an)GB706-88標準選(xuan)擇。
吊(diao)(diao)鉤(gou)(gou)：采用(yong)優(you)質碳素鋼制造，通(tong)過單列滾(gun)動推力軸承(cheng)支承(cheng)在吊(diao)(diao)橫梁上能自由旋轉擺動。0.5-5t采用(yong)單滑(hua)輪式(shi)吊(diao)(diao)鉤(gou)(gou)裝置(zhi)，10t采用(yong)雙滑(hua)輪式(shi)吊(diao)(diao)鉤(gou)(gou)裝置(zhi)，并鉤(gou)(gou)尾部均采用(yong)卡板(ban)式(shi)結(jie)構，使之拆(chai)卸方便(bian)。當方便(bian)等級為dIICT4時(shi)，吊(diao)(diao)鉤(gou)(gou)鉤(gou)(gou)頭采用(yong)不銹(xiu)鋼（或不銹(xiu)鋼包(bao)戶）。
限位(wei)器(qi)：為防止吊(diao)鉤超出上(shang)升極限位(wei)置，造(zao)成鋼絲繩(sheng)被拉斷的(de)事故，或(huo)下降時(shi)超出極限值，而使(shi)導繩(sheng)器(qi)與(yu)壓繩(sheng)棋逢(feng)對手(shou)擠壓損壞造(zao)成鋼絲繩(sheng)脫離卷筒的(de)事故，采(cai)用(yong)起升高度(du)限位(wei)器(qi)，以保證(zheng)吊(diao)鉤達到上(shang)、下兩極限位(wei)置時(shi)，及(ji)時(shi)切斷起升電動機的(de)供電，即通過導繩(sheng)器(qi)迫使(shi)限位(wei)桿運動，切斷起升開關，保證(zheng)安全。
防(fang)爆(bao)(bao)電(dian)動(dong)(dong)機(ji)：系專(zhuan)用制(zhi)造的(de)全封閉錐形轉子(zi)異步(bu)電(dian)動(dong)(dong)機(ji)。防(fang)爆(bao)(bao)電(dian)動(dong)(dong)機(ji)的(de)大轉矩為滿載(zai)的(de)2-3倍，以(yi)適應防(fang)爆(bao)(bao)電(dian)動(dong)(dong)葫(hu)蘆(lu)繼(ji)續工(gong)作之(zhi)直接(jie)(jie)起(qi)動(dong)(dong)。本系列防(fang)爆(bao)(bao)電(dian)動(dong)(dong)葫(hu)蘆(lu)的(de)運(yun)行防(fang)爆(bao)(bao)電(dian)動(dong)(dong)機(ji)，本身帶有制(zhi)動(dong)(dong)器，當電(dian)機(ji)斷電(dian)后，可以(yi)使防(fang)爆(bao)(bao)電(dian)動(dong)(dong)葫(hu)蘆(lu)在較短時間內停止。起(qi)升機(ji)運(yun)行用防(fang)爆(bao)(bao)電(dian)動(dong)(dong)機(ji)的(de)外(wai)殼(ke)材料采(cai)用HT200高(gao)級(ji)鑄鐵(tie)。加工(gong)后進行1分鐘的(de)水壓(ya)試(shi)驗，接(jie)(jie)線盒內的(de)接(jie)(jie)線柱采(cai)用4220號耐電(dian)弧壓(ya)塑粉壓(ya)制(zhi)而成(cheng)。
