瀝青攤鋪機(jī)在現(xiàn)實(shí)的工程運(yùn)行過程中，可能會(huì)出現(xiàn)各種各樣的故障或問題，有時(shí)因此會(huì)嚴(yán)重影響了整個(gè)施工。因此，在實(shí)際工程中如何正確操作和保養(yǎng)以及處理已經(jīng)出現(xiàn)的故障并予以維修就顯得非常重要。下面來進(jìn)行瀝青攤鋪機(jī)自動(dòng)調(diào)平系統(tǒng)故障分析吧。

During the actual operation of the asphalt paver, various failures or problems may occur, sometimes seriously affecting the whole construction. Therefore, how to operate and maintain correctly and how to deal with the faults and repair them in the actual project is very important. The following is the fault analysis of the automatic leveling system of the asphalt paver.

濟(jì)南攤鋪機(jī)出租提醒，振搗錘在液壓馬達(dá)驅(qū)動(dòng)下，進(jìn)行有規(guī)律不一致振動(dòng)，從而增加攤鋪密實(shí)度。連接馬達(dá)與偏心器的連接軸內(nèi)的鋼絲軸斷裂、軸承卡死、馬達(dá)從動(dòng)齒輪軸的連接叉斷裂、馬達(dá)從動(dòng)齒輪軸承卡死等原因會(huì)導(dǎo)致振搗棒不振。此類況可以更換齒輪副、密封圈，重新裝上鋼絲軸的方法來排除。

Jinan paver rental reminds that the tamping hammer, driven by the hydraulic motor, vibrates regularly and inconsistently, thus increasing the paving compactness. The steel wire shaft in the connecting shaft connecting the motor and the eccentric is broken, the bearing is stuck, the connecting fork of the motor driven gear shaft is broken, the motor driven gear bearing is stuck and other reasons will lead to the vibration of the vibrator. Such cases can be eliminated by replacing the gear pair and sealing ring and refitting the steel wire shaft.

振搗棒的離心器損壞可能會(huì)引起出現(xiàn)振搗棒振動(dòng)無力，此時(shí)就抽出離心器，并檢查離心器兩端的軸承、振動(dòng)馬達(dá)輸出軸的支承軸承及密封圈，更新、裝復(fù)即可。在操作過程中，切忌在振搗無力時(shí)不要加大振動(dòng)頻率，這樣可能會(huì)加速振搗棒的損壞，平時(shí)多注意并及時(shí)加注潤滑脂。

The damage of the centrifuge of the vibrating rod may cause the vibration of the vibrating rod to be weak. At this time, pull out the centrifuge, check the bearings at both ends of the centrifuge, the supporting bearings and sealing rings of the output shaft of the vibrating motor, and replace them. During the operation, do not increase the vibration frequency when the vibration is weak, which may accelerate the damage of the vibrator. Pay more attention to it and add grease in time.

自動(dòng)調(diào)平系統(tǒng)的工作情況是影響路面攤鋪質(zhì)量的重要因素。在實(shí)際工作中發(fā)現(xiàn)影響攤鋪平整度的因素很多，如攤鋪速度的頻繁變化、攤鋪機(jī)熨平板底板與路面水平面夾角的大小、混合料溫度的明顯改變及攤鋪中混合料的多少等，均可造成攤鋪質(zhì)量缺陷。

The working condition of the automatic leveling system is an important factor affecting the pavement quality. In the actual work, it is found that many factors affect the paving smoothness, such as the frequent change of paving speed, the size of the included angle between the screed bottom plate of the paver and the pavement level, the obvious change of the mixture temperature and the amount of mixture during paving, all of which can cause paving quality defects.

此時(shí)應(yīng)立即停止向攤鋪機(jī)料斗供料，在將料斗中剩余的瀝青混合料攤鋪完后，關(guān)閉自動(dòng)找平按鈕，用手動(dòng)操縱按鈕將上升的支腿放下，再檢查掛線高度。若是機(jī)身前后高度差超過標(biāo)準(zhǔn)，則需重新調(diào)整傳感器的高度值。

At this time, stop feeding the hopper of the paver immediately. After paving the remaining asphalt mixture in the hopper, turn off the automatic leveling button, use the manual control button to lower the rising outrigger, and then check the hanging height. If the front and rear height difference of the fuselage exceeds the standard, the height value of the sensor shall be readjusted.

其次濟(jì)南攤鋪機(jī)出租人員認(rèn)為拆卸有故障的縱坡傳感器，用萬用表檢查觸桿與滑變電阻相連的傳感器軸轉(zhuǎn)動(dòng)時(shí)，其兩可變電阻的阻值變化情況是否有規(guī)律，如沒有規(guī)律表示可變電阻出了問題。

Secondly, the lessor of Jinan paver thinks that the faulty longitudinal slope sensor should be removed, and the multimeter should be used to check whether the resistance of the two variable resistors changes regularly when the sensor shaft connected with the contact rod and the sliding resistance rotates. If there is no law, it means that the variable resistor has a problem.
