自拌混凝土搅拌车属于特种车辆,不是能开车就能开好搅拌车的,搅拌车操作不当会引起翻车、配件过快磨损等状况,除了影响施工,造成不必要的经济损失以外,甚至呈现愈加严重的后果。想要开好搅拌车,你得紧记以下几条:
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.搅拌车发动机发动后,应该先让拌和筒低速作业10分钟左右,使液压油温升到20℃以上后方可作业。
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.搅拌车装料前应将拌和筒反转,确保仓斗内的积水和杂物排出,这样能够确保混凝土的质量,确保施工质量。
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.搅拌车在运输混凝土时,要确保滑斗放置结实,防止因松动造成摇摆,在行进中打伤行人或影响其它车辆正常运转。在运输过程中,平整路面上拌和筒转速确保在2-3转/分,行进在侧倾坡度大于50的路面,或左右晃动较大的路面时,应停止拌和旋转,待路况好转后再恢复拌和旋转。
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.自拌混凝土搅拌车运送混凝土的时刻不能超越拌和站规则的时刻。运送混凝土途中,拌和筒不得长时刻停转,以防混凝土发生离析现象。司机应时常调查混凝土状况,发现异常及时通报调度室,申请做出处理。
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. 拌和罐车装有混凝土时,在现场停滞时刻不得超越1小时,如超时应立即要求现场负责人给予及时处理。
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. 搅拌车运送混凝土塌落度不得低于8cm。从混凝土入罐到排出,气温高时不得超越2小时必须排出,阴雨气候温度低时,不得超越2.5小时。
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. 搅拌车在排出混凝土之前,应使拌和筒在10-12转/分的转速下滚动1分钟,再进行排料。
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. 自拌混凝土搅拌车出料完毕,应立即用随车的软管放水将进料口、出料斗及出料溜槽等部位冲洗洁净,排去粘结在车身遍地的污物及残留混凝土,再向拌和筒内灌水150-200L的清水,在返回途中要让拌和筒慢速滚动,以清洗内壁,防止残余料渣附在筒壁和拌和叶上,并在再一次装料前将这些水放掉。
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. 混凝土搅拌车运送混凝土时,发动机转速在1000-1400转/分范围内作业,以使发动机有大扭距,在运送混凝土过程中,车速不得超越40km/h,以保行车安全。
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. 水泥搅拌车作业完毕,应把拌和筒内部和车身清洗洁净,不能使剩余的混凝土留在筒内。
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.
