在使用到一定時間之后,過多過少的會出現(xiàn)拌筒不能轉(zhuǎn)動,一般有3種情況:
After use for a certain period of time, the mixing drum will not rotate if there are too many or too few. Generally, there are three situations:
1、運輸過程中有混泥土卡住了;
1. Concrete gets stuck during transportation;
2、液壓系統(tǒng)或發(fā)動機(jī)發(fā)生故障;
2. Failure of hydraulic system or engine;
3、馬達(dá)發(fā)生故障。
3. The motor has failed.
應(yīng)對方法:
Countermeasures:
1、運輸過程中有混泥土卡住了;清理干凈就沒有問題了;
1. Concrete gets stuck during transportation; Clean up and there will be no problem;
2、液壓系統(tǒng)或發(fā)動機(jī)故障的處理:
2. Troubleshooting of hydraulic system or engine:
(1)打開攪拌筒檢修孔蓋,旋松馬達(dá)上高壓軟管的管接頭,旋轉(zhuǎn)拌筒使拌筒檢修孔斜向下,將砼從攪拌筒檢修孔排出;
(1) Open the mixing drum manhole cover, unscrew the pipe joint of the high-pressure hose on the motor, rotate the mixing drum so that the mixing drum manhole is inclined downward, and discharge the concrete from the mixing drum manhole;
(2)將故障車的高壓膠管從馬達(dá)上卸下,把救援用的高壓膠管接上,另一端接在救援車的油泵上,并將應(yīng)急用的回油管一端接在故障車的馬達(dá)泄油口,回油管另一端接在救援車的油泵回油口,利用救援車來控制故障車拌筒的旋轉(zhuǎn),將砼排出。
(2) Remove the high-pressure rubber hose of the failed vehicle from the motor, connect the high-pressure rubber hose for rescue, connect the other end to the oil pump of the rescue vehicle, connect one end of the emergency oil return pipe to the motor drain port of the failed vehicle, and connect the other end of the oil return pipe to the oil return port of the oil pump of the rescue vehicle. Use the rescue vehicle to control the rotation of the mixing drum of the failed vehicle and discharge the concrete.
3、馬達(dá)發(fā)生故障,處理則較簡單,可把救援車的馬達(dá)卸下裝在故障車上,再將各個油管接好,啟動救援車即可將拌筒內(nèi)的砼排出。
3. In case of motor failure, the treatment is relatively simple. Remove the motor of the rescue vehicle and install it on the failed vehicle, connect each oil pipe, and start the rescue vehicle to discharge the concrete in the mixing drum.
小型混凝土攪拌車作為運輸用汽車,在維護(hù)和修理方面須遵照交通部的規(guī)定,執(zhí)行“定期檢測、強(qiáng)制維護(hù)、視情修理”的維修制度。在這個大前提下,再結(jié)合混凝土攪拌運輸車的實際情況,做好維護(hù)和修理。在日常維護(hù)方面,混凝土攪拌運輸車除應(yīng)按常規(guī)對汽車發(fā)動機(jī)、底盤等部位進(jìn)行維護(hù)外,還須做好以下維護(hù)工作。
As a transport vehicle, the maintenance and repair of small concrete mixer shall comply with the provisions of the Ministry of communications and implement the maintenance system of "regular inspection, compulsory maintenance and repair as appropriate". On this premise, combined with the actual situation of concrete mixer truck, do a good job in maintenance and repair. In terms of daily maintenance, the concrete mixer truck shall not only maintain the vehicle engine, chassis and other parts according to the routine, but also do the following maintenance work.
