自动上来哦混凝土搅拌车的组成

所属分类:企业资讯 发布时间:2021-11-30 来源:/ 浏览量:18

随着湿凝土生产和施工技本的迅速发展,在20世纪70年代后期,我国逐渐采用了混凝土集中搅拌、商品化供应的方式,混凝土由专门的混凝土搅拌站提供,再由混凝土搅拌运辘车运送到备施工场所。现简要先容混凝土搅拌车的结构原理及其维修做。
With the rapid development of wet concrete production and construction technology, in the late 1970s, China gradually adopted the mode of centralized mixing and commercial supply of concrete. The concrete is provided by a special concrete mixing plant and then transported to the preparation workshop by a concrete mixing roller truck. This paper briefly introduces the structural principle and maintenance of concrete mixer.
混凝土自动上料搅拌车由汽车底盘和混凝土搅拌运输专用装置组成。我国生产的混凝土自动上料搅拌车的底盘多采用整车生产厂家提供的二类通用底盘。
The automatic concrete loading mixer is composed of an automobile chassis and a special device for concrete mixing and transportation. The chassis of automatic concrete loading mixer truck produced in China mostly adopts class II general chassis provided by vehicle manufacturers.
其专用机构主要包括取力器、搅拌简前后支架、减速机、液压系统、搅拌筒、操纵机构、清洗系统等。其工作原理:通过取力装置将汽车底盘的动力取出,并驱动液压系统的变量泵,把机械能转化为液压能传给定量马选,马达再驱动减速机,由减速机驱动搅拌装置,对混凝土进行搅拌。
Its special mechanism mainly includes power takeoff, front and rear support of mixing box, reducer, hydraulic system, mixing drum, control mechanism, cleaning system, etc. Its working principle: take out the power of the automobile chassis through the power take-off device, drive the variable pump of the hydraulic system, convert the mechanical energy into hydraulic energy and transmit it to the quantitative horse selection, the motor drives the reducer, and the reducer drives the mixing device to mix the concrete.
因此,要求汽车底盘有足够的载重能力和强劲的输出功率:一般要求发动机要有230 kw(300马力)以上的功率,装载量为6~7一的混凝土搅搀运输车需选用6×4载质量为15 t级的通用底盘,装载量为8~10 m3的需选用双前桥8×4载质量为20t级的底盘,而装载繁为IO~i2m3的则要采用6×4的牵gI车加半挂车的方式。
Therefore, the vehicle chassis is required to have sufficient load capacity and strong output power: generally, the engine is required to have a power of more than 230 kW (300 HP), and the concrete mixing transport vehicle with a loading capacity of 6 ~ 7 needs to choose 6 × 4. For general chassis with a load capacity of 15 t and a load capacity of 8 ~ 10 m3, double front axle 8 shall be selected × 4 chassis with load mass of 20t, and chassis with load of IO ~ i2m3 shall be adopted × 4. The way of pulling GI vehicle and semi-trailer.
混凝土自动上料搅拌车的组成及工作原理
Composition and working principle of automatic concrete loading mixer
1)取力装置
1) Power take-off device
国产混凝土自动上料搅拌车采用毛车发动机取力方式。取力装置的作用是通过操纵取力开关将发动机动力取出,经液压系统驱动搅拌筒,搅抖筒在进料和运输过程中正向旋转,以利于进料和对混凝土进行搅拌,在出料时反向旋转,在工作终结詹切断与发动机的动力联接。
The domestic concrete automatic loading mixer adopts the power taking mode of rough car engine. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, drive the mixing drum through the hydraulic system, and the mixing drum rotates forward in the process of feeding and transportation, so as to facilitate feeding and mixing of concrete, rotate reversely during discharging, and cut off the power connection with the engine at the end of work.
2)液压系统
2) Hydraulic system
将经取力器取出的发动机动力,转化为液压能(排量承i压力),再经马达输出为机械能(转速和摇矩),为搅拌筒转动提供动力。
The engine power taken out by the power take-off is converted into hydraulic energy (displacement bearing I pressure), and then output into mechanical energy (speed and shaking moment) by the motor to provide power for the rotation of the mixing drum.
3)减速机
3) Reducer
将液压系统中马达输出的转速减速后,传给搅拌筒。
The speed output by the motor in the hydraulic system is decelerated and transmitted to the mixing drum.
4)操纵机构
4) Operating mechanism
a.控制搅拌筒旋转方向,使之在进料和运输过程中正向旋转,出料时反向旋转。
a. Control the rotation direction of the mixing drum to make it rotate forward during feeding and transportation and reverse during discharging.
b.控制搅拌筒的转速。
b. Control the rotating speed of the mixing drum.

5)搅拌装置
5) Mixing device
它主要由搅拌篱及其辅助支撑部佧组成。搅拌筒是混凝土的装载容器,它是由耐磨薄钢板制成,为了能够自动装、卸混凝±,其内壁焊有特殊形状的螺旋叶片。转动时混凝土沿叶片的螺旋方向运动,在不断的提升和翻动过程中受到混合和搅拌。在进料及运输过程中,搅拌筒正转,混凝土沿叶片向里运动,出料时,搅拌筒反转,混凝土沿着叶片向外雠出。搅拌筒的转动剥是靠液压驱动装置来保证。装载量为6~8 m3的混凝土自动上料搅拌车一般采用由汽车发动机通过动力输出轴带动液压泵,再由高匿油推动液压马达驱动搅拌筒,装载量为9~12 m3的则由车载辅助柴油机带动液压泵驱动液压马达。叶片是搅拌装置中的主要部件,损坏或严重黪损会导致混凝土搅拌不均匀。另外,叶片的角度如果设计不合理,还会使混凝土出现离析。
It is mainly composed of mixing fence and its auxiliary support part. The mixing drum is a concrete loading container, which is made of wear-resistant steel sheet. In order to automatically load and unload concrete ±, its inner wall is welded with spiral blades of special shape. When rotating, the concrete moves along the spiral direction of the blade and is mixed and stirred in the process of continuous lifting and turning. During feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blade. When discharging, the mixing drum reverses, and the concrete is discharged outward along the blade. The rotation of the mixing drum is ensured by the hydraulic driving device. The automatic concrete loading mixer with a loading capacity of 6 ~ 8 m3 generally uses the hydraulic pump driven by the automobile engine through the power output shaft, and then the hydraulic motor driven by the high hidden oil to drive the mixing drum. For the mixer with a loading capacity of 9 ~ 12 m3, the hydraulic pump driven by the on-board auxiliary diesel engine drives the hydraulic motor. Blade is the main component of mixing device. Damage or serious damage will lead to uneven mixing of concrete. In addition, if the design of blade angle is unreasonable, the concrete will be separated.
6)清洗系统
6) Cleaning system
清洗系统的主婴作用是清洗搅拌筒,有时也用于运输途中进行于料搅拌。清洗系统还对液压系统起冷却作用。
The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for material mixing during transportation. The cleaning system also cools the hydraulic system.
