液壓千斤頂使用注意事項
1液(ye)壓(ya)千(qian)斤頂(ding)在(zai)頂(ding)升(sheng)(sheng)作業(ye)時(shi)(shi),要(yao)選擇合適噸位的(de)液(ye)壓(ya)千(qian)斤頂(ding):承載能(neng)力(li)不可超負荷,選擇液(ye)壓(ya)千(qian)斤頂(ding)的(de)承載能(neng)力(li)需(xu)大于(yu)(yu)重(zhong)物(wu)重(zhong)力(li)的(de)1.2倍;液(ye)壓(ya)千(qian)斤頂(ding)最低高度合適,為了便于(yu)(yu)取出,選用液(ye)壓(ya)千(qian)斤頂(ding)的(de)最小高度應與重(zhong)物(wu)底部施力(li)處的(de)凈空相適應,起落過程中墊枕木支持重(zhong)物(wu)時(shi)(shi),液(ye)壓(ya)千(qian)斤頂(ding)的(de)起升(sheng)(sheng)高度要(yao)大于(yu)(yu)枕木厚度與枕木變(bian)形之和(he)。
2若使用(yong)多臺(tai)液(ye)壓千斤頂(ding)頂(ding)升(sheng)同一設備時,應選用(yong)同一型號的(de)(de)液(ye)壓千斤頂(ding),且每臺(tai)液(ye)壓千斤頂(ding)的(de)(de)額定(ding)起(qi)重量之和不得小于所承擔設備重力(li)的(de)(de)1.5倍。
3液壓千斤頂在使用前應擦拭干(gan)凈,并應檢查(cha)各部(bu)件(jian)是否靈活,有(you)無損傷(shang),在有(you)載荷時切忌將快速接頭卸(xie)下,以(yi)免發(fa)生事故(gu)及損壞部(bu)件(jian)。
4液壓(ya)(ya)(ya)千斤(jin)頂(ding)在使(shi)用(yong)前應放置(zhi)平整,不能(neng)傾(qing)斜,底(di)(di)部(bu)要(yao)墊(dian)(dian)平,嚴防(fang)地(di)基偏沉(chen)或載荷偏移而(er)使(shi)液壓(ya)(ya)(ya)千斤(jin)頂(ding)傾(qing)斜或翻倒,可在液壓(ya)(ya)(ya)千斤(jin)頂(ding)底(di)(di)部(bu)墊(dian)(dian)堅韌的(de)枕(zhen)術(shu)或鋼板(ban)來擴大承壓(ya)(ya)(ya)面(mian)積(ji),以免陷落或滑動(dong)而(er)發生事故;切(qie)勿用(yong)有油污的(de)木板(ban)或鋼板(ban)作(zuo)為襯墊(dian)(dian),防(fang)止(zhi)受(shou)力時打滑,發生安全事故;重物被頂(ding)升位置(zhi)必須是安全、堅實的(de)部(bu)位,以防(fang)損壞設(she)備。
5使用液(ye)壓(ya)(ya)千(qian)(qian)斤(jin)(jin)頂(ding)(ding)(ding)時(shi),應先(xian)將(jiang)重物先(xian)試頂(ding)(ding)(ding)起一部分(fen),仔細檢查液(ye)壓(ya)(ya)千(qian)(qian)斤(jin)(jin)頂(ding)(ding)(ding)無異常后(hou),再繼(ji)續頂(ding)(ding)(ding)升重物。若(ruo)發現(xian)墊板受(shou)壓(ya)(ya)后(hou)不(bu)平(ping)整(zheng)、不(bu)牢固或(huo)液(ye)壓(ya)(ya)千(qian)(qian)斤(jin)(jin)頂(ding)(ding)(ding)有傾(qing)斜時(shi),必須將(jiang)液(ye)壓(ya)(ya)千(qian)(qian)斤(jin)(jin)頂(ding)(ding)(ding)卸壓(ya)(ya)回(hui)程,及時(shi)處理(li)好后(hou)方可(ke)再次操(cao)作。
6在頂(ding)升過程中,應(ying)隨(sui)重(zhong)物的不斷上升及時在液壓千斤頂(ding)下方鋪墊保險枕(zhen)木(mu)架,以防液壓千斤頂(ding)傾斜(xie)或引起活塞突然下降而造成事故,下放(fang)重(zhong)物時要逐步向(xiang)外抽出(chu)枕(zhen)木(mu),枕(zhen)木(mu)與重(zhong)物間的距離不得超過一塊(kuai)枕(zhen)木(mu)的厚度,以防意外!
7若重(zhong)物的頂(ding)升高度需超出液壓千(qian)斤頂(ding)額定高度時,需先在液壓千(qian)斤頂(ding)頂(ding)起(qi)的重(zhong)物下(xia)墊好枕木,降下(xia)液壓千(qian)斤頂(ding),墊高其底部(bu),重(zhong)復頂(ding)升,直(zhi)至(zhi)需要的起(qi)升高度。
8液(ye)(ye)壓千斤(jin)頂不可作(zuo)為(wei)永久支(zhi)承(cheng)設(she)備(bei)。如需長時間支(zhi)承(cheng),應在重(zhong)物(wu)下方增(zeng)加支(zhi)承(cheng)部(bu)分,以保(bao)證液(ye)(ye)壓千斤(jin)頂不受損壞(huai)。
9若頂(ding)(ding)升重(zhong)物(wu)一(yi)(yi)端只用(yong)一(yi)(yi)臺液(ye)(ye)壓千斤(jin)頂(ding)(ding)時,則應(ying)將液(ye)(ye)壓千斤(jin)頂(ding)(ding)放(fang)置在重(zhong)物(wu)的(de)(de)對稱(cheng)軸(zhou)線上,并使液(ye)(ye)壓千斤(jin)頂(ding)(ding)底座長的(de)(de)方向(xiang)和重(zhong)物(wu)易(yi)傾倒的(de)(de)方向(xiang)一(yi)(yi)致(zhi)。若重(zhong)物(wu)一(yi)(yi)端使用(yong)兩臺液(ye)(ye)壓千斤(jin)頂(ding)(ding)時,其底座的(de)(de)方向(xiang)應(ying)略呈(cheng)八字形對稱(cheng)放(fang)置于重(zhong)物(wu)對稱(cheng)軸(zhou)線兩側。
10使(shi)用兩(liang)臺或多臺液壓(ya)千(qian)斤頂同(tong)(tong)時(shi)頂升作(zuo)業時(shi),須統一指(zhi)揮、協調一致、同(tong)(tong)時(shi)升降。
11液(ye)壓千(qian)斤頂(ding)應存放(fang)在干燥、無塵的地方,不(bu)適宜在有酸堿,腐蝕性氣(qi)體的工作場(chang)所使用,更不(bu)能(neng)放(fang)在室(shi)外(wai)日曬雨淋!
操作時應嚴格遵守技術規范,用戶需根據使用情況定期檢查和保養。
