多功能混凝土攪拌車若是出現(xiàn)故障的話，那么不是會(huì)對(duì)車輛本身造成危害，更重要的是攪拌車內(nèi)的混凝土也會(huì)受到波及，若是混凝土因?yàn)槎喙δ芑炷翑嚢柢嚨墓收隙塘说脑挘敲磳?huì)造成非常的損失，所以為了避免這種情況的發(fā)生，當(dāng)發(fā)現(xiàn)混凝土攪拌車有故障發(fā)生的時(shí)候，應(yīng)當(dāng)及時(shí)找出故障點(diǎn)進(jìn)行解決。

If the multi-functional concrete mixer fails, it will not cause harm to the vehicle itself. More importantly, the concrete in the mixer truck will also be affected. If the concrete solidifies due to the fault of the multi-functional concrete mixer, it will cause extraordinary losses. Therefore, in order to avoid this situation, when the concrete mixer truck is found to have fault When the fault occurs, it is necessary to find out the fault point and solve it in time.

一、罐體轉(zhuǎn)動(dòng)工作原理

1、 Working principle of can body rotation

發(fā)動(dòng)機(jī)取力器——傳動(dòng)軸——油泵——馬達(dá)——減速機(jī)——罐體轉(zhuǎn)動(dòng)

Engine power take-off - transmission shaft - oil pump - motor - reducer - can body rotation

二、原因分析

2、 Cause analysis

導(dǎo)致多功能混凝土攪拌車攪拌罐停轉(zhuǎn)主要有以下原因：

The main reasons for the stop of mixing tank of multi-functional concrete mixer are as follows:

1.發(fā)動(dòng)機(jī)故障：發(fā)動(dòng)機(jī)無法啟動(dòng)、取力器損壞等原因

1. Engine failure: the engine cannot be started and the power take-off is damaged

2.上裝故障：傳動(dòng)軸損壞、油泵故障、液壓油過臟或油量不足、馬達(dá)故障、減速機(jī)故障、操縱桿松脫等原因。

2. Upper mounting fault: transmission shaft damage, oil pump failure, hydraulic oil too dirty or insufficient, motor failure, reducer failure, control rod loose and other reasons.

三、尋找故障點(diǎn)

3、 Find the fault point

當(dāng)多功能混凝土攪拌車運(yùn)送混凝土過程中，發(fā)生罐體無法轉(zhuǎn)動(dòng)故障，應(yīng)停車進(jìn)行檢查。通過“一聽、一看、一動(dòng)”迅速尋找故障點(diǎn)，“一聽”是指從傳動(dòng)軸到減速機(jī)各零部件有無發(fā)出異響；“一看”是指看液壓油箱油位是否過低或管路漏油嚴(yán)重；“一動(dòng)”是指前后扳動(dòng)油泵伺服桿，罐體是否正反均無轉(zhuǎn)動(dòng)。

When the multi-functional concrete mixer truck can't rotate in the process of transporting concrete, it should be stopped for inspection. Through "one listen, one look, one move" to quickly find out the fault point. "One listen" refers to whether the parts from the transmission shaft to the reducer make abnormal noise; "one look" refers to whether the oil level of the hydraulic oil tank is too low or the pipeline has serious oil leakage; "moving" refers to pulling the servo rod of the oil pump back and forth, and whether the tank body does not rotate in both positive and negative directions.

注：應(yīng)在罐體停止轉(zhuǎn)動(dòng)后緊急聯(lián)系當(dāng)?shù)胤?wù)人員(附通訊錄)，告知罐內(nèi)混凝土標(biāo)號(hào)及預(yù)凝時(shí)間，服務(wù)人員會(huì)耐心指導(dǎo)您如何處理，同時(shí)請(qǐng)您將車輛開至就近服務(wù)站。

Note: after the tank stops rotating, contact the local service personnel (attached with the address book) to inform the concrete mark number and pre setting time in the tank. The service personnel will guide you how to handle it patiently. At the same time, please drive the vehicle to the nearest service station.

四、應(yīng)急措施

4、 Emergency measures

如果不能在混凝土預(yù)凝之前將自上料混凝土攪拌車修復(fù)，應(yīng)立即采取應(yīng)急措施：

If the self loading concrete mixer cannot be repaired before the concrete is pre set, emergency measures shall be taken immediately:

1.馬達(dá)和減速機(jī)無故障情況下，連接“應(yīng)急油管”將混凝土卸出，預(yù)防凝灌事故發(fā)生。

1. When the motor and reducer have no fault, connect the "emergency oil pipe" to unload the concrete, so as to prevent the occurrence of condensation grouting accident.

2.馬達(dá)或減速機(jī)發(fā)生故障且確定無法在混凝土預(yù)凝前使罐體轉(zhuǎn)動(dòng)，請(qǐng)快速打開人孔蓋，如人孔蓋不在罐體下方則需要在罐體前錐底部開孔(Φ=1250px，避開原有焊道)，與此同時(shí)必須持續(xù)向進(jìn)料口灌入大量清水，沖刷罐內(nèi)混凝土，直至罐體下方無混凝土流出，罐內(nèi)少量殘余混凝土需人工進(jìn)行清理，清理完畢后進(jìn)行清洗，將割下部分重新焊接到混凝土攪拌車罐體上(安裝人孔蓋)，并打磨噴漆處理。
