人員(yuan)在(zai)進行絲桿升(sheng)降機上進行時重要(yao)的(de)是就是保障自身保險。必須嚴格(ge)依(yi)照(zhao)標準的(de)操(cao)作請求進行操(cao)作,并佩戴保險防護(hu)器具(ju)。那么,設(she)備中保險防護(hu)器具(ju)都有哪些(xie)呢?
一(yi)、保險(xian)(xian)帽(mao)(mao):在利用前要檢(jian)查帽(mao)(mao)殼(ke)、帽(mao)(mao)襯、帽(mao)(mao)帶是(shi)否齊全(quan)有效(xiao)。利用保險(xian)(xian)帽(mao)(mao)前先調劑保險(xian)(xian)帽(mao)(mao)襯,使(shi)帽(mao)(mao)襯各(ge)局(ju)部(bu)與帽(mao)(mao)殼(ke)相距一(yi)定(ding)空間(jian)。還要帽(mao)(mao)箍應依(yi)據人頭型來(lai)調劑箍緊,以(yi)防抬頭作(zuo)業時(shi)帽(mao)(mao)子前滑擋住視線。嚴禁將保險(xian)(xian)帽(mao)(mao)兩層頂襯合為(wei)一(yi)層。保險(xian)(xian)帽(mao)(mao)應戴(dai)緊、戴(dai)正,帽(mao)(mao)帶應系在頜下(xia)并系緊。保險(xian)(xian)帽(mao)(mao)的(de)有效(xiao)期限從產品制造實現之日起盤算,塑料(liao)帽(mao)(mao)不超過兩年(nian)半(ban)(ban),玻(bo)璃鋼帽(mao)(mao)不超過三年(nian)半(ban)(ban)。
二(er)、保險(xian)(xian)帶(dai):保險(xian)(xian)帶(dai)必(bi)須(xu)每半(ban)年(nian)經(jing)過(guo)考試(shi)單(dan)位考試(shi)及(ji)格后方可利用。利用保險(xian)(xian)帶(dai)須(xu)要滿意一(yi)些前提:有可能進行絲桿升降(jiang)機的(de)工(gong)作,在(zai)(zai)進入(ru)工(gong)作場合時,身上(shang)必(bi)須(xu)佩(pei)有保險(xian)(xian)帶(dai);高(gao)度超過(guo)兩米的(de)時;在(zai)(zai)不腳手架(jia)或(huo)者不攔桿的(de)腳手架(jia)上(shang)工(gong)作,高(gao)度超過(guo)1.5米時;傾斜的(de)屋頂作業(ye)時;平(ping)頂屋,在(zai)(zai)離屋頂邊(bian)沿或(huo)屋頂開(kai)口1.2米內不防護欄時;任(ren)何(he)(he)懸吊的(de)平(ping)臺或(huo)工(gong)作臺;任(ren)何(he)(he)護欄,鋪板不完全的(de)腳手架(jia)上(shang);瀕臨屋面或(huo)地面開(kai)孔(kong)鄰近的(de)梯子上(shang);高(gao)處作業(ye)無堅固防墜落辦法時。
另外(wai),正確利(li)(li)(li)用(yong)(yong)(yong)(yong)也是十分重要的(de),那么如何正確利(li)(li)(li)用(yong)(yong)(yong)(yong)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)呢?要束緊腰帶(dai)(dai),腰扣(kou)組(zu)件必(bi)須系(xi)緊系(xi)正;利(li)(li)(li)用(yong)(yong)(yong)(yong)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)進行懸掛(gua)作業時(shi),不(bu)能將(jiang)掛(gua)勾(gou)直接(jie)勾(gou)在保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)繩上,應勾(gou)在保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)繩的(de)掛(gua)環上;禁止將(jiang)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)掛(gua)在不(bu)堅固(gu)或帶(dai)(dai)尖利(li)(li)(li)角的(de)構件上;利(li)(li)(li)用(yong)(yong)(yong)(yong)一起類型(xing)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai),各部件不(bu)能擅自調換;受到重大沖擊(ji)的(de)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai),即(ji)便外(wai)型(xing)未變也不(bu)可(ke)利(li)(li)(li)用(yong)(yong)(yong)(yong);嚴(yan)禁利(li)(li)(li)用(yong)(yong)(yong)(yong)保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)來(lai)傳遞重物;保(bao)(bao)險(xian)(xian)(xian)帶(dai)(dai)要掛(gua)在上方堅固(gu)堅固(gu)處,高度不(bu)低于腰部。
三(san)、保(bao)(bao)險(xian)(xian)(xian)繩(sheng)(sheng):為保(bao)(bao)障(zhang)人員(yuan)在(zai)(zai)挪動進(jin)程中始終有保(bao)(bao)險(xian)(xian)(xian)保(bao)(bao)障(zhang),當進(jin)行特別(bie)危險(xian)(xian)(xian)絲(si)桿升降(jiang)機作業時,請求在(zai)(zai)系好保(bao)(bao)險(xian)(xian)(xian)帶的(de)同時,系掛在(zai)(zai)保(bao)(bao)險(xian)(xian)(xian)繩(sheng)(sheng)上;保(bao)(bao)險(xian)(xian)(xian)繩(sheng)(sheng)的(de)材質有一(yi)定(ding)的(de)標(biao)準(zhun)禁止利(li)用(yong)麻繩(sheng)(sheng)來做(zuo)保(bao)(bao)險(xian)(xian)(xian)繩(sheng)(sheng)。絲(si)桿升降(jiang)機通常升降(jiang)機基(ji)本上有快(kuai)慢兩種速度,這是蝸(gua)輪蝸(gua)桿傳動比決定(ding)的(de)。利(li)用(yong)3米(mi)以上的(de)長(chang)繩(sheng)(sheng)要加(jia)緩沖器;一(yi)條保(bao)(bao)險(xian)(xian)(xian)繩(sheng)(sheng)不能兩人同時利(li)用(yong)。
四、差速(su)(su)維(wei)護器:自(zi)鎖(suo)器在利(li)用前應進(jin)行檢查(cha);自(zi)鎖(suo)器掛鉤,應掛在保險(xian)帶(dai)金(jin)屬環上(shang)(shang);受過重(zhong)大(da)沖擊的自(zi)鎖(suo)器應當結束利(li)用。螺旋(xuan)升(sheng)降機(ji)由(you)蝸(gua)(gua)輪(lun)(lun)蝸(gua)(gua)桿、箱體、軸承、絲(si)杠(gang)等零(ling)部件組成(cheng)。工作(zuo)原理為:電機(ji)或者(zhe)手(shou)動(dong)(dong)驅(qu)動(dong)(dong)蝸(gua)(gua)桿旋(xuan)轉(zhuan),蝸(gua)(gua)桿驅(qu)動(dong)(dong)蝸(gua)(gua)輪(lun)(lun)減速(su)(su)旋(xuan)轉(zhuan),蝸(gua)(gua)輪(lun)(lun)內(nei)腔(qiang)加工為內(nei)螺紋,驅(qu)動(dong)(dong)絲(si)杠(gang)上(shang)(shang)下移動(dong)(dong),由(you)于內(nei)部有(you)蝸(gua)(gua)輪(lun)(lun)蝸(gua)(gua)桿,絲(si)杠(gang)的減速(su)(su)作(zuo)用,達到放大(da)推力(li)的作(zuo)用。絲(si)桿升(sheng)降機(ji)通常升(sheng)降機(ji)基本上(shang)(shang)有(you)快慢兩種速(su)(su)度,這(zhe)是蝸(gua)(gua)輪(lun)(lun)蝸(gua)(gua)桿傳動(dong)(dong)比決定的。
