薄型千斤頂輕型緊(jin)湊設計(ji)用于狹小工作空間，烤漆表(biao)面曾強耐腐蝕(shi)能力。
    按結構特征可分為齒條(tiao)千斤頂、螺旋(xuan)千斤頂和液壓千斤頂3種(zhong)。千斤(jin)頂(ding)是一種(zhong)起重(zhong)(zhong)高度小(xiao) (小(xiao)于1m)的(de)較(jiao)簡(jian)單的(de)起重(zhong)(zhong)設(she)備。它有(you)機械(xie)式(shi)和(he)液(ye)壓式(shi)兩種(zhong)。機械(xie)式(shi)千斤(jin)頂(ding)又有(you)齒條式(shi)與(yu)螺(luo)旋式(shi)兩種(zhong)，由于起重(zhong)(zhong)量小(xiao)，操作(zuo)費力(li)，一般只(zhi)用(yong)(yong)于機械(xie)維修(xiu)工作(zuo)，在修(xiu)橋過程中不適用(yong)(yong)。液(ye)壓式(shi)千斤(jin)頂(ding)結構緊(jin)湊，工作(zuo)平穩，有(you)自鎖作(zuo)用(yong)(yong)，故(gu)使(shi)用(yong)(yong)廣泛。其缺點是起重(zhong)(zhong)高度有(you)限，起升速度慢。
工作原理
    千斤頂分為機械千斤頂和液壓千斤頂兩種，原(yuan)(yuan)理(li)(li)(li)各(ge)有不(bu)(bu)同(tong)。從原(yuan)(yuan)理(li)(li)(li)上(shang)來(lai)(lai)說，液壓(ya)千斤頂(ding)所(suo)基于的(de)(de)(de)(de)原(yuan)(yuan)理(li)(li)(li)為(wei)帕斯卡原(yuan)(yuan)理(li)(li)(li)，即：液體各(ge)處(chu)的(de)(de)(de)(de)壓(ya)強是(shi)(shi)一致的(de)(de)(de)(de)，這樣(yang)，在平衡(heng)的(de)(de)(de)(de)系統中，比(bi)較小(xiao)(xiao)的(de)(de)(de)(de)活塞(sai)上(shang)面(mian)施加的(de)(de)(de)(de)壓(ya)力比(bi)較小(xiao)(xiao)，而大的(de)(de)(de)(de)活塞(sai)上(shang)施加的(de)(de)(de)(de)壓(ya)力也(ye)比(bi)較大，這樣(yang)能夠(gou)保持液體的(de)(de)(de)(de)靜止(zhi)。所(suo)以(yi)(yi)通(tong)過液體的(de)(de)(de)(de)傳遞，可以(yi)(yi)得(de)到(dao)不(bu)(bu)同(tong)端上(shang)的(de)(de)(de)(de)不(bu)(bu)同(tong)的(de)(de)(de)(de)壓(ya)力，這樣(yang)就(jiu)可以(yi)(yi)達到(dao)一個變換的(de)(de)(de)(de)目的(de)(de)(de)(de)。我們所(suo)常見到(dao)的(de)(de)(de)(de)液壓(ya)千斤頂(ding)就(jiu)是(shi)(shi)利(li)用了這個原(yuan)(yuan)理(li)(li)(li)來(lai)(lai)達到(dao)力的(de)(de)(de)(de)傳遞。機械(xie)千斤頂(ding)采(cai)用機械(xie)原(yuan)(yuan)理(li)(li)(li)，以(yi)(yi)往復扳動(dong)手柄，拔爪即推動(dong)棘輪間(jian)隙回(hui)轉，小(xiao)(xiao)傘(san)齒(chi)輪帶動(dong)大傘(san)齒(chi)輪、使舉(ju)重螺桿旋轉，從而使升降套筒獲得(de)起(qi)升或(huo)下降，而達到(dao)起(qi)重拉力的(de)(de)(de)(de)功(gong)能。但不(bu)(bu)如液壓(ya)千斤頂(ding)簡易。
簡介
    千(qian)(qian)斤(jin)頂(ding)是一(yi)種起(qi)重(zhong)高度(du)(du)小(小于(yu)1m)的(de)(de)較(jiao)簡(jian)單的(de)(de)起(qi)重(zhong)設備。它有(you)(you)機(ji)械(xie)式和液壓(ya)式兩(liang)種。機(ji)械(xie)式千(qian)(qian)斤(jin)頂(ding)又有(you)(you)齒條(tiao)式與螺旋式兩(liang)種，由于(yu)起(qi)重(zhong)量小，操作(zuo)(zuo)(zuo)(zuo)費力，一(yi)般(ban)只(zhi)用(yong)于(yu)機(ji)械(xie)維修工作(zuo)(zuo)(zuo)(zuo)，在修橋過(guo)程中不適用(yong)。液壓(ya)式千(qian)(qian)斤(jin)頂(ding)結構緊湊，工作(zuo)(zuo)(zuo)(zuo)平穩，有(you)(you)自(zi)鎖作(zuo)(zuo)(zuo)(zuo)用(yong)，故使(shi)用(yong)廣泛。其(qi)(qi)缺點是起(qi)重(zhong)高度(du)(du)有(you)(you)限，起(qi)升速(su)度(du)(du)慢。千(qian)(qian)斤(jin)頂(ding)主要(yao)用(yong)于(yu)廠(chang)礦、交通運輸等(deng)部門作(zuo)(zuo)(zuo)(zuo)為車輛修理(li)及其(qi)(qi)它起(qi)重(zhong)、支撐等(deng)工作(zuo)(zuo)(zuo)(zuo)。其(qi)(qi)結構輕巧堅(jian)固、靈活可靠，一(yi)人即(ji)可攜(xie)帶和操作(zuo)(zuo)(zuo)(zuo)。千(qian)(qian)斤(jin)頂(ding)作(zuo)(zuo)(zuo)(zuo)為一(yi)種使(shi)用(yong)范(fan)圍廣泛的(de)(de)工具，采(cai)用(yong)了較(jiao)優(you)質的(de)(de)材(cai)料(liao)鑄造，保證了千(qian)(qian)斤(jin)頂(ding)的(de)(de)質量和使(shi)用(yong)壽命(ming)。
分類
    1、按結構特(te)征可分(fen)為齒(chi)條千(qian)斤(jin)(jin)(jin)頂(ding)(ding)、螺旋（機械）千(qian)斤(jin)(jin)(jin)頂(ding)(ding)和(he)液壓（油壓）千(qian)斤(jin)(jin)(jin)頂(ding)(ding)3種。 　　  千(qian)斤(jin)(jin)(jin)頂(ding)(ding)
① 齒條(tiao)千(qian)斤(jin)(jin)頂(ding):由人力(li)(li)(li)通過(guo)杠桿(gan)和齒輪(lun)帶動(dong)(dong)齒條(tiao)頂(ding)舉重物。起(qi)重量(liang)一般不超過(guo)20噸，可長(chang)(chang)期支(zhi)持(chi)(chi)(chi)重物，主(zhu)要用在作業條(tiao)件不方便的地(di)方或需要利用下部(bu)的托爪提(ti)升重物的場(chang)合，如鐵(tie)路(lu)起(qi)軌作業。② 螺(luo)(luo)(luo)(luo)旋千(qian)斤(jin)(jin)頂(ding):由人力(li)(li)(li)通過(guo)螺(luo)(luo)(luo)(luo)旋副(fu)傳(chuan)動(dong)(dong)，螺(luo)(luo)(luo)(luo)桿(gan)或螺(luo)(luo)(luo)(luo)母套筒作為頂(ding)舉件。普通螺(luo)(luo)(luo)(luo)旋千(qian)斤(jin)(jin)頂(ding)靠螺(luo)(luo)(luo)(luo)紋自鎖作用支(zhi)持(chi)(chi)(chi)重物，構造簡單，但傳(chuan)動(dong)(dong)效率低，返程(cheng)慢(man)。自降螺(luo)(luo)(luo)(luo)旋千(qian)斤(jin)(jin)頂(ding)的螺(luo)(luo)(luo)(luo)紋無自鎖作用，但裝(zhuang)有制動(dong)(dong)器。放松制動(dong)(dong)器，重物即(ji)可自行快速下降，縮(suo)短(duan)返程(cheng)時間，但這種(zhong)千(qian)斤(jin)(jin)頂(ding)構造較(jiao)復雜。螺(luo)(luo)(luo)(luo)旋千(qian)斤(jin)(jin)頂(ding)能長(chang)(chang)期支(zhi)持(chi)(chi)(chi)重物，較(jiao)大起(qi)重量(liang)已達(da)100噸，應用較(jiao)廣。下部(bu)裝(zhuang)上(shang)水平(ping)螺(luo)(luo)(luo)(luo)桿(gan)后，還能使重物做小距離橫(heng)移(yi)。③ 液壓千(qian)斤(jin)(jin)頂(ding):由人力(li)(li)(li)或電力(li)(li)(li)驅動(dong)(dong)液壓泵(beng)，通過(guo)液壓系統傳動，用缸(gang)體(ti)或(huo)活塞作為頂(ding)(ding)(ding)舉件。液(ye)壓千斤(jin)頂(ding)(ding)(ding)可分(fen)(fen)(fen)為整體(ti)式和分(fen)(fen)(fen)離(li)式。整體(ti)式的(de)泵與(yu)液(ye)壓缸(gang)聯成(cheng)一體(ti)；分(fen)(fen)(fen)離(li)式的(de)泵與(yu)液(ye)壓缸(gang)分(fen)(fen)(fen)離(li)，中間用高壓軟管相聯。液(ye)壓千斤(jin)頂(ding)(ding)(ding)結構緊(jin)湊，能平穩頂(ding)(ding)(ding)升(sheng)重(zhong)(zhong)物(wu)，起重(zhong)(zhong)量較(jiao)大達1000噸，行程1米，傳動效(xiao)率較(jiao)高，故(gu)應用較(jiao)廣；但易(yi)漏(lou)油，不(bu)宜長期支持(chi)重(zhong)(zhong)物(wu)。 如長期支撐需選用自鎖(suo)千斤(jin)頂(ding)(ding)(ding)，螺(luo)旋千斤(jin)頂(ding)(ding)(ding)和液(ye)壓千斤(jin)頂(ding)(ding)(ding)為進一步降低外(wai)形高度或(huo)增大頂(ding)(ding)(ding)舉距(ju)離(li)，可做成(cheng)多級伸縮(suo)式。 液(ye)壓千斤(jin)頂(ding)(ding)(ding)除上述基本(ben)型(xing)式外(wai)，按同樣原理可改(gai)裝(zhuang)成(cheng)滑升(sheng)模(mo)板千斤(jin)頂(ding)(ding)(ding)、液(ye)壓升(sheng)降臺、張拉機等，用于各(ge)種特殊施工(gong)場合(he)。
