自動(dòng)上來(lái)哦混凝土攪拌車(chē)的組成

所屬分類(lèi)：公司新聞發(fā)布時(shí)間：2021-11-30 來(lái)源：http://www.akware.net/ 瀏覽量：0

隨著(zhù)濕凝土生產(chǎn)和施工技本的迅速發(fā)展，在20世紀70年代后期，我國逐漸采用了混凝土集中攪拌、商品化供應的方式，混凝土由專(zhuān)門(mén)的混凝土攪拌站提供，再由混凝土攪拌運轆車(chē)運送到備施工場(chǎng)所?，F簡(jiǎn)要介紹混凝土攪拌車(chē)的結構原理及其維修做。

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.

混凝土自動(dòng)上料攪拌車(chē)由汽車(chē)底盤(pán)和混凝土攪拌運輸專(zhuān)用裝置組成。我國生產(chǎn)的混凝土自動(dòng)上料攪拌車(chē)的底盤(pán)多采用整車(chē)生產(chǎn)廠(chǎng)家提供的二類(lèi)通用底盤(pán)。

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.

其專(zhuān)用機構主要包括取力器、攪拌簡(jiǎn)前后支架、減速機、液壓系統、攪拌筒、操縱機構、清洗系統等。其工作原理：通過(guò)取力裝置將汽車(chē)底盤(pán)的動(dòng)力取出，并驅動(dòng)液壓系統的變量泵，把機械能轉化為液壓能傳給定量馬選，馬達再驅動(dòng)減速機，由減速機驅動(dòng)攪拌裝置，對混凝土進(jìn)行攪拌。

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，要求汽車(chē)底盤(pán)有足夠的載重能力和強勁的輸出功率：一般要求發(fā)動(dòng)機要有230 kw（300馬力）以上的功率，裝載量為6～7一的混凝土攪攙運輸車(chē)需選用6×4載質(zhì)量為15 t級的通用底盤(pán)，裝載量為8～10 m3的需選用雙前橋8×4載質(zhì)量為20t級的底盤(pán)，而裝載繁為IO～i2m3的則要采用6×4的牽gI車(chē)加半掛車(chē)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.

混凝土自動(dòng)上料攪拌車(chē)的組成及工作原理

Composition and working principle of automatic concrete loading mixer

1）取力裝置

1) Power take-off device

國產(chǎn)混凝土自動(dòng)上料攪拌車(chē)采用毛車(chē)發(fā)動(dòng)機取力方式。取力裝置的作用是通過(guò)操縱取力開(kāi)關(guān)將發(fā)動(dòng)機動(dòng)力取出，經(jīng)液壓系統驅動(dòng)攪拌筒，攪抖筒在進(jìn)料和運輸過(guò)程中正向旋轉，以利于進(jìn)料和對混凝土進(jìn)行攪拌，在出料時(shí)反向旋轉，在工作終結詹切斷與發(fā)動(dòng)機的動(dòng)力聯(lián)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）液壓系統

2) Hydraulic system

將經(jīng)取力器取出的發(fā)動(dòng)機動(dòng)力，轉化為液壓能（排量承i壓力），再經(jīng)馬達輸出為機械能（轉速和搖矩），為攪拌筒轉動(dòng)提供動(dòng)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）減速機

3) Reducer

將液壓系統中馬達輸出的轉速減速后，傳給攪拌筒。

The speed output by the motor in the hydraulic system is decelerated and transmitted to the mixing drum.

4）操縱機構

4) Operating mechanism

a.控制攪拌筒旋轉方向，使之在進(jìn)料和運輸過(guò)程中正向旋轉，出料時(shí)反向旋轉。

a. Control the rotation direction of the mixing drum to make it rotate forward during feeding and transportation and reverse during discharging.

b.控制攪拌筒的轉速。

b. Control the rotating speed of the mixing drum.

5）攪拌裝置

5) Mixing device

它主要由攪拌籬及其輔助支撐部佧組成。攪拌筒是混凝土的裝載容器，它是由耐磨薄鋼板制成，為了能夠自動(dòng)裝、卸混凝±，其內壁焊有特殊形狀的螺旋葉片。轉動(dòng)時(shí)混凝土沿葉片的螺旋方向運動(dòng)，在不斷的提升和翻動(dòng)過(guò)程中受到混合和攪拌。在進(jìn)料及運輸過(guò)程中，攪拌筒正轉，混凝土沿葉片向里運動(dòng)，出料時(shí)，攪拌筒反轉，混凝土沿著(zhù)葉片向外讎出。攪拌筒的轉動(dòng)剝是靠液壓驅動(dòng)裝置來(lái)保證。裝載量為6～8 m3的混凝土自動(dòng)上料攪拌車(chē)一般采用由汽車(chē)發(fā)動(dòng)機通過(guò)動(dòng)力輸出軸帶動(dòng)液壓泵，再由高匿油推動(dòng)液壓馬達驅動(dòng)攪拌筒，裝載量為9～12 m3的則由車(chē)載輔助柴油機帶動(dòng)液壓泵驅動(dòng)液壓馬達。葉片是攪拌裝置中的主要部件，損壞或嚴重黲損會(huì )導致混凝土攪拌不均勻。另外，葉片的角度如果設計不合理，還會(huì )使混凝土出現離析。

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）清洗系統

6) Cleaning system

清洗系統的主嬰作用是清洗攪拌筒，有時(shí)也用于運輸途中進(jìn)行于料攪拌。清洗系統還對液壓系統起冷卻作用。

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.
