自拌混凝土攪拌車(chē)屬于特種車(chē)輛,不是能開(kāi)車(chē)就能開(kāi)好攪拌車(chē)的,攪拌車(chē)操作不當會(huì )引起翻車(chē)、配件過(guò)快磨損等狀況,除了影響施工,造成不必要的經(jīng)濟損失以外,甚呈現愈加嚴重的后果。想要開(kāi)好攪拌車(chē),你得緊記以下幾條:
The self mixing concrete mixer is a special vehicle, which can not drive well. Improper operation of the mixer will cause overturning, rapid wear of accessories and other conditions. In addition to affecting the construction and causing unnecessary economic losses, it even presents more and more serious consequences. To drive a good mixer, you have to remember the following:
1.攪拌車(chē)發(fā)動(dòng)機發(fā)動(dòng)后,應該先讓拌和筒低速作業(yè)10分鐘左右,使液壓油溫升到20℃以上后方可作業(yè)。
1. After the mixer engine is started, the mixing drum should be allowed to operate at low speed for about 10 minutes, and the hydraulic oil temperature should be raised to above 20 ℃.
2.攪拌車(chē)裝料前應將拌和筒反轉,確保倉斗內的積水和雜物排出,這樣能夠確?;炷恋馁|(zhì)量,確保施工質(zhì)量。
2. Before loading, the mixing drum should be reversed to ensure the discharge of water and debris in the hopper, so as to ensure the quality of concrete and construction quality.
3.攪拌車(chē)在運輸混凝土時(shí),要確?;贩胖媒Y實(shí),防止因松動(dòng)造成搖擺,在行進(jìn)中打傷行人或影響其它車(chē)輛正常運轉。在運輸過(guò)程中,平整路面上拌和筒轉速確保在2-3轉/分,行進(jìn)在側傾坡度大于50的路面,或左右晃動(dòng)較大的路面時(shí),應停止拌和旋轉,待路況好轉后再恢復拌和旋轉。
3. When transporting concrete, the mixer truck shall ensure that the sliding bucket is firmly placed to prevent swinging due to looseness, injuring pedestrians or affecting the normal operation of other vehicles. In the process of transportation, the rotation speed of the mixing drum on the level road surface should be 2-3 rpm. When moving on the road with a roll slope greater than 50 or the road with large left and right shaking, the mixing rotation should be stopped, and the mixing rotation should be resumed after the road condition is improved.
4.自拌混凝土攪拌車(chē)運送混凝土的時(shí)刻不能超越拌和站規則的時(shí)刻。運送混凝土途中,拌和筒不得長(cháng)時(shí)刻停轉,以防混凝土發(fā)生離析現象。司機應時(shí)常調查混凝土狀況,發(fā)現異常及時(shí)通報調度室,申請做出處理。
4. The time of transporting concrete by self mixing concrete mixer truck should not exceed the time of mixing station rules. During the transportation of concrete, the mixing drum shall not stop for a long time to prevent concrete segregation. The driver should always investigate the concrete condition, report to the dispatching room in time if any abnormality is found, and apply for handling.
5. 拌和罐車(chē)裝有混凝土時(shí),在現場(chǎng)停滯時(shí)刻不得超越1小時(shí),如超時(shí)應立即要求現場(chǎng)負責人給予及時(shí)處理。
5. When the mixing tank truck is equipped with concrete, it shall not exceed 1 hour at the time of stagnation on site. If it exceeds the time limit, the person in charge of the site shall be required to deal with it in time.
6. 攪拌車(chē)運送混凝土塌落度不得低于8cm。從混凝土入罐到排出,氣溫高時(shí)不得超越2小時(shí)必須排出,陰雨氣候溫度低時(shí),不得超越2.5小時(shí)。
6. The slump of concrete transported by mixer truck shall not be less than 8cm. From the time the concrete is put into the tank to discharged, it must be discharged within 2 hours when the temperature is high, and it must be discharged within 2.5 hours when the temperature is low in rainy weather.
7. 攪拌車(chē)在排出混凝土之前,應使拌和筒在10-12轉/分的轉速下滾動(dòng)1分鐘,再進(jìn)行排料。
7. Before discharging the concrete, the mixer should roll the mixing drum at the speed of 10-12 rpm for 1 minute before discharging.
8. 自拌混凝土攪拌車(chē)出料完畢,應立即用隨車(chē)的軟管放水將進(jìn)料口、出料斗及出料溜槽等部位沖洗潔凈,排去粘結在車(chē)身遍地的污物及殘留混凝土,再向拌和筒內灌水150-200L的清水,在返回途中要讓拌和筒慢速滾動(dòng),以清洗內壁,防止殘余料渣附在筒壁和拌和葉上,并在再一次裝料前將這些水放掉。
eight After the discharge of the self mixing concrete mixer, the feeding port, discharge hopper, discharge chute and other parts shall be cleaned immediately with the hose attached to the truck, and the dirt and residual concrete bonded on the car body shall be removed. Then, 150-200l clean water shall be poured into the mixing drum. On the way back, the mixing drum shall be allowed to roll slowly to clean the inner wall, so as to prevent the residual slag from adhering to the wall and mixing leaves, And discharge the water before loading again.
9. 混凝土攪拌車(chē)運送混凝土時(shí),發(fā)動(dòng)機轉速在1000-1400轉/分范圍內作業(yè),以使發(fā)動(dòng)機有大扭距,在運送混凝土過(guò)程中,車(chē)速不得超越40km/h,以保行車(chē)。
9. When the concrete mixer transports concrete, the engine speed should be in the range of 1000-1400 rpm to make the engine have large torque. In the process of transporting concrete, the speed should not exceed 40km / h to ensure driving safety.
10. 水泥攪拌車(chē)作業(yè)完畢,應把拌和筒內部和車(chē)身清洗潔凈,不能使剩余的混凝土留在筒內。
10. After the operation of cement mixer, the inside and body of mixing drum shall be cleaned, and the remaining concrete shall not be left in the drum.
