薄型(xing)千斤頂輕型緊(jin)湊設計用(yong)于狹小(xiao)工作空間，烤漆表面(mian)曾(ceng)強耐腐蝕(shi)能力。
    按結構(gou)特征可(ke)分為(wei)齒條千斤頂、螺旋千斤頂和液壓千斤頂3種。千(qian)斤頂(ding)是一(yi)種起(qi)重(zhong)(zhong)高(gao)度小(xiao) (小(xiao)于1m)的(de)(de)較(jiao)簡單的(de)(de)起(qi)重(zhong)(zhong)設(she)備。它有機械(xie)式和液壓式兩(liang)種。機械(xie)式千(qian)斤頂(ding)又(you)有齒條(tiao)式與(yu)螺旋式兩(liang)種，由于起(qi)重(zhong)(zhong)量(liang)小(xiao)，操作(zuo)費力，一(yi)般只(zhi)用(yong)于機械(xie)維(wei)修(xiu)工(gong)作(zuo)，在(zai)修(xiu)橋過(guo)程中不適(shi)用(yong)。液壓式千(qian)斤頂(ding)結構緊湊，工(gong)作(zuo)平穩(wen)，有自鎖作(zuo)用(yong)，故使用(yong)廣(guang)泛。其缺點是起(qi)重(zhong)(zhong)高(gao)度有限，起(qi)升速度慢。
工作原理
    千(qian)斤(jin)頂分為機(ji)械(xie)千(qian)斤(jin)頂和液壓千斤頂兩種，原(yuan)(yuan)理(li)(li)各(ge)有不同(tong)。從(cong)原(yuan)(yuan)理(li)(li)上來說，液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)千斤(jin)(jin)頂(ding)所基于的(de)(de)(de)原(yuan)(yuan)理(li)(li)為帕斯(si)卡原(yuan)(yuan)理(li)(li)，即：液(ye)(ye)(ye)體各(ge)處的(de)(de)(de)壓(ya)(ya)(ya)(ya)強是一(yi)致的(de)(de)(de)，這(zhe)樣(yang)，在平衡的(de)(de)(de)系統中，比較(jiao)小(xiao)的(de)(de)(de)活塞上面施加的(de)(de)(de)壓(ya)(ya)(ya)(ya)力比較(jiao)小(xiao)，而大的(de)(de)(de)活塞上施加的(de)(de)(de)壓(ya)(ya)(ya)(ya)力也(ye)比較(jiao)大，這(zhe)樣(yang)能(neng)夠保持(chi)液(ye)(ye)(ye)體的(de)(de)(de)靜止。所以(yi)通過(guo)液(ye)(ye)(ye)體的(de)(de)(de)傳遞，可以(yi)得到不同(tong)端上的(de)(de)(de)不同(tong)的(de)(de)(de)壓(ya)(ya)(ya)(ya)力，這(zhe)樣(yang)就可以(yi)達到一(yi)個(ge)變換(huan)的(de)(de)(de)目的(de)(de)(de)。我們所常見到的(de)(de)(de)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)千斤(jin)(jin)頂(ding)就是利用了這(zhe)個(ge)原(yuan)(yuan)理(li)(li)來達到力的(de)(de)(de)傳遞。機械千斤(jin)(jin)頂(ding)采用機械原(yuan)(yuan)理(li)(li)，以(yi)往復扳動手柄(bing)，拔爪即推動棘輪(lun)(lun)間隙回轉，小(xiao)傘齒輪(lun)(lun)帶動大傘齒輪(lun)(lun)、使舉重(zhong)螺桿(gan)旋轉，從(cong)而使升降套筒(tong)獲得起升或下降，而達到起重(zhong)拉力的(de)(de)(de)功能(neng)。但不如液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)千斤(jin)(jin)頂(ding)簡易。
簡介
    千(qian)斤(jin)頂是(shi)一種起(qi)(qi)重(zhong)高度(du)小(小于(yu)1m)的較(jiao)簡單(dan)的起(qi)(qi)重(zhong)設備(bei)。它有機械式(shi)和液壓式(shi)兩種。機械式(shi)千(qian)斤(jin)頂又有齒條式(shi)與螺旋式(shi)兩種，由于(yu)起(qi)(qi)重(zhong)量(liang)小，操(cao)作費力，一般只用(yong)于(yu)機械維修(xiu)工作，在修(xiu)橋過程中不適用(yong)。液壓式(shi)千(qian)斤(jin)頂結(jie)(jie)構緊湊，工作平穩，有自鎖作用(yong)，故使(shi)用(yong)廣(guang)泛。其(qi)缺點(dian)是(shi)起(qi)(qi)重(zhong)高度(du)有限，起(qi)(qi)升(sheng)速(su)度(du)慢(man)。千(qian)斤(jin)頂主(zhu)要用(yong)于(yu)廠(chang)礦(kuang)、交(jiao)通運輸等(deng)部門作為(wei)(wei)車輛修(xiu)理及其(qi)它起(qi)(qi)重(zhong)、支(zhi)撐等(deng)工作。其(qi)結(jie)(jie)構輕巧堅固、靈活可靠，一人即可攜帶和操(cao)作。千(qian)斤(jin)頂作為(wei)(wei)一種使(shi)用(yong)范圍(wei)廣(guang)泛的工具(ju)，采用(yong)了(le)較(jiao)優質的材(cai)料鑄造，保(bao)證了(le)千(qian)斤(jin)頂的質量(liang)和使(shi)用(yong)壽命。
分類(lei)
    1、按結(jie)構特征可(ke)分為齒條千(qian)斤頂(ding)、螺旋（機械）千(qian)斤頂(ding)和液壓（油壓）千(qian)斤頂(ding)3種。 　　  千(qian)斤頂(ding)
① 齒(chi)(chi)條(tiao)(tiao)千(qian)斤(jin)(jin)頂:由人力通(tong)過杠桿和齒(chi)(chi)輪帶動齒(chi)(chi)條(tiao)(tiao)頂舉重(zhong)(zhong)物(wu)(wu)(wu)(wu)。起(qi)重(zhong)(zhong)量(liang)一般不(bu)超過20噸，可長(chang)期(qi)支(zhi)持重(zhong)(zhong)物(wu)(wu)(wu)(wu)，主要(yao)用(yong)在作(zuo)(zuo)業條(tiao)(tiao)件不(bu)方(fang)便的(de)地(di)方(fang)或需要(yao)利用(yong)下部的(de)托爪提升(sheng)重(zhong)(zhong)物(wu)(wu)(wu)(wu)的(de)場合，如(ru)鐵(tie)路起(qi)軌(gui)作(zuo)(zuo)業。② 螺(luo)(luo)旋千(qian)斤(jin)(jin)頂:由人力通(tong)過螺(luo)(luo)旋副(fu)傳動，螺(luo)(luo)桿或螺(luo)(luo)母套筒作(zuo)(zuo)為頂舉件。普通(tong)螺(luo)(luo)旋千(qian)斤(jin)(jin)頂靠螺(luo)(luo)紋自鎖作(zuo)(zuo)用(yong)支(zhi)持重(zhong)(zhong)物(wu)(wu)(wu)(wu)，構造簡(jian)單，但(dan)傳動效率(lv)低，返程(cheng)慢(man)。自降螺(luo)(luo)旋千(qian)斤(jin)(jin)頂的(de)螺(luo)(luo)紋無自鎖作(zuo)(zuo)用(yong)，但(dan)裝有制動器。放松制動器，重(zhong)(zhong)物(wu)(wu)(wu)(wu)即可自行快速下降，縮(suo)短返程(cheng)時間，但(dan)這種千(qian)斤(jin)(jin)頂構造較復雜。螺(luo)(luo)旋千(qian)斤(jin)(jin)頂能長(chang)期(qi)支(zhi)持重(zhong)(zhong)物(wu)(wu)(wu)(wu)，較大起(qi)重(zhong)(zhong)量(liang)已達100噸，應用(yong)較廣。下部裝上水平螺(luo)(luo)桿后，還能使重(zhong)(zhong)物(wu)(wu)(wu)(wu)做小距離橫(heng)移。③ 液(ye)壓千(qian)斤(jin)(jin)頂:由人力或電(dian)力驅動液(ye)壓泵，通(tong)過液壓系統傳動(dong)，用(yong)缸(gang)體(ti)或活塞作(zuo)為頂舉件(jian)。液(ye)壓(ya)(ya)(ya)千(qian)斤(jin)(jin)頂可分為整體(ti)式和分離式。整體(ti)式的(de)泵與(yu)(yu)液(ye)壓(ya)(ya)(ya)缸(gang)聯成一體(ti)；分離式的(de)泵與(yu)(yu)液(ye)壓(ya)(ya)(ya)缸(gang)分離，中間用(yong)高(gao)(gao)壓(ya)(ya)(ya)軟(ruan)管相聯。液(ye)壓(ya)(ya)(ya)千(qian)斤(jin)(jin)頂結構緊(jin)湊，能平(ping)穩頂升(sheng)重物(wu)，起重量較(jiao)大達1000噸(dun)，行(xing)程1米，傳動(dong)效率較(jiao)高(gao)(gao)，故應(ying)用(yong)較(jiao)廣；但易漏(lou)油，不(bu)宜(yi)長期(qi)支持(chi)重物(wu)。 如長期(qi)支撐需(xu)選用(yong)自鎖千(qian)斤(jin)(jin)頂，螺旋千(qian)斤(jin)(jin)頂和液(ye)壓(ya)(ya)(ya)千(qian)斤(jin)(jin)頂為進一步降低外形高(gao)(gao)度或增大頂舉距離，可做成多級伸縮式。 液(ye)壓(ya)(ya)(ya)千(qian)斤(jin)(jin)頂除上述基本型式外，按同樣原理(li)可改裝成滑(hua)升(sheng)模板千(qian)斤(jin)(jin)頂、液(ye)壓(ya)(ya)(ya)升(sheng)降臺、張拉(la)機等，用(yong)于各種(zhong)特殊施(shi)工場(chang)合(he)。
