起重機(jī)在運(yùn)行過程中是否發(fā)生啃軌現(xiàn)象，可根據(jù)下列跡象來判斷：1.鋼軌側(cè)面有明亮的痕跡，嚴(yán)重的痕跡上帶有毛刺；車輪輪緣的內(nèi)側(cè)有亮斑。2.鋼軌頂面有亮斑。3.起重機(jī)在運(yùn)行過程中，在很短的一段距離內(nèi)，車輪輪緣與鋼軌側(cè)面之間的間隙發(fā)生明顯的改變。4.起重機(jī)在起動(dòng)或制動(dòng)時(shí)，車體走斜、扭擺。防止車輪啃軌的措施對(duì)于集中驅(qū)動(dòng)和分別驅(qū)動(dòng)的運(yùn)行機(jī)構(gòu)，青島剛性起重導(dǎo)軌供應(yīng)商，防止和改善起重機(jī)車輪啃軌的方法應(yīng)有所不同。可通過仔細(xì)檢查，認(rèn)真調(diào)整，糾正車輪和鋼軌的不準(zhǔn)確安裝，特別要注意分別驅(qū)動(dòng)運(yùn)行機(jī)構(gòu)兩側(cè)電動(dòng)機(jī)、制動(dòng)器和減速器存在的不同步問題。1.限制橋架跨度L和輪距K的比值。橋式起重機(jī)在正常運(yùn)行過程中，允許車輪輪緣與鋼軌之間有一定的自由斜度，即允許車輪輪緣與鋼軌側(cè)面之間有一定的橫向移動(dòng)距離(一般為20～30mm)。這個(gè)距離越大，越不會(huì)發(fā)生啃軌現(xiàn)象。另外，是否發(fā)生啃軌現(xiàn)象還與L/K的比值有關(guān)，比值越大，允許的自由歪斜越小，越容易發(fā)生啃軌現(xiàn)象，所以應(yīng)取較小的L/K值。經(jīng)驗(yàn)表明，L/K值小于5～6時(shí)較為有利。2.集中驅(qū)動(dòng)的運(yùn)行機(jī)構(gòu)如車輪總數(shù)為4個(gè)，其中2個(gè)為主動(dòng)車輪，主動(dòng)車輪踏面可采用圓錐形踏面(錐度為1：10)，并將錐面的大端向內(nèi)安裝，青島剛性起重導(dǎo)軌供應(yīng)商，青島剛性起重導(dǎo)軌供應(yīng)商，采用凸頂鋼軌。

起重機(jī)軌道的安裝方式——用于安裝軌道的軌道梁常用的有2種:一種是鋼結(jié)構(gòu)梁，一種是混凝土預(yù)制梁?；炷令A(yù)制梁必須留有預(yù)埋孔，以備安裝時(shí)穿螺栓，或者在混凝土預(yù)制梁中預(yù)埋螺栓。——起重機(jī)軌道的安裝方法有用壓板固定法、鉤形螺桿固定、焊接和螺栓聯(lián)用固定等。為了進(jìn)行水平方向的調(diào)整，軌道壓板上的孔通常做成長孔，垂直方向的調(diào)整可在鋼軌下加墊。——軌道壓板在設(shè)計(jì)時(shí)，要具有足夠的剛性，每塊壓板，根據(jù)受力的大小可以制成單孔的或雙孔的。只有軌道與軌道梁或者軌道梁上固定的鋼墊板采用焊接方式連接時(shí)，車檔方可焊接在軌道上。 </p> <p> <br /> </p> <p> <br /> </p><p> 起重機(jī)軌道都有接頭，由于金屬軌道受溫度影響，長度有變化，因此在軌道對(duì)接處都留有一定間隙。這個(gè)間隙造成了起重機(jī)車輪運(yùn)行時(shí)的沖擊、振動(dòng)。為了減小這種沖擊和振動(dòng)，可對(duì)其稍作改動(dòng)，在安裝形式與連接尺寸不變的情況下，將軌道兩端沿軸線成45度方向銑掉。這樣，在軌道安裝后，軌道接頭處的間隙就不是垂直于軌道軸線的一條直縫，而是傾斜于軌道軸線45度的斜縫，改進(jìn)后的軌道接頭供熱伸長的長度沒有變，但間隙比原來的小，即原軌道接頭間隙不變，當(dāng)車輪經(jīng)過這種斜接口軌道接頭時(shí)，產(chǎn)生的沖擊、振動(dòng)也相應(yīng)減小了。從圖1可以看到，當(dāng)車輪還未走完前一根軌道時(shí)，就已經(jīng)走上后面的軌道了，這就使得車輪經(jīng)過接頭時(shí)沖擊和振動(dòng)明顯減小。如果這種斜接口軌道接頭處存在高低差，則車輪經(jīng)過時(shí)會(huì)先與尖角點(diǎn)1發(fā)生碰撞、摩擦，容易在短時(shí)間內(nèi)磨去其尖角，而原來的直接口軌道接頭在車輪經(jīng)過時(shí)，無論接頭處有無高低差，車輪都要沖擊軌道整個(gè)端部，很難消除。斜接頭軌道接頭安裝方法與原軌道接頭相同，工藝簡單，加工要求低。但是，當(dāng)軌道比較小時(shí)，使用45度斜切口就不合適了。因?yàn)檫@種軌道的腹板比較薄，斜切后，接頭處軌道的腹板就變得非常薄，在車輪的沖擊和振動(dòng)作用下，接頭處容易被損壞。

剛性導(dǎo)軌是2000年以后歐美外國公司引入中國的導(dǎo)軌，代替了KBK導(dǎo)軌初的設(shè)計(jì)缺陷：1.成型KBK軌道通過兩條扎帶進(jìn)行焊接，因此必須產(chǎn)生制造商控制的變形和焊接質(zhì)量。硬軌由一次冷軋形成，有效避免了二次焊接變形等質(zhì)量問題。2.主光束偏斜KBK采用圓頭柔性連接，因此在運(yùn)行主梁時(shí)，一端會(huì)緩慢啟動(dòng)，另一端會(huì)偏斜，主梁偏斜，停止后會(huì)反彈，這會(huì)影響定位精度。由于所有剛性導(dǎo)軌都是剛性連接的，因此主梁的兩端開始同時(shí)運(yùn)行，并且定位更加準(zhǔn)確。3.單雙光束和凈空由于軌道強(qiáng)度和配件（汽車和主梁吊架）的限制，當(dāng)噸位超過1噸或1噸的跨度超過8m時(shí)，KBK必須采用雙梁設(shè)計(jì)。剛性軌道桁架設(shè)計(jì)可確保在2t以內(nèi)使用單個(gè)梁。KBK本身必須使用附加的I型鋼軸承梁作為支撐以增加其凈空。剛性軌道桁架設(shè)計(jì)的應(yīng)用可確保較小的凈空高度并減少鋼材消耗。更輕巧簡潔。4.連接安全KBK軌道和工字鋼支承梁，軌道和主梁連桿均使用柔性連接，例如螺栓，圓珠筆，夾板。結(jié)構(gòu)靈活，震動(dòng)很大，因此需要螺栓和其他潛在的安全隱患，需要定期檢查和維護(hù)。所有的剛性導(dǎo)軌都用厚鋼板和**度長螺釘牢固地固定。軌道和主梁之間的連接通過套管固定。徹底消除搖擺空間，安全可靠。
