攪拌一體車在工程建筑中使用的很多,攪拌車上的零配件有很多,在它們的共同作用下攪拌車才能正常的工作,來看一下攪拌車的主要零配件的性能。攪拌筒是攪拌車上主要的部分之一,攪拌筒的作用是非常重要的,它跟攪拌車的使用壽命是息息相關(guān)的,攪拌筒主要是由筒體、密封管、葉片等部分組成,漏斗狀的密封管能夠確保順利進料,曲面狀的葉片有助于地塌落度混凝土的出料性能,在葉片上有孔眼,能減少混凝土在其上的粘附,有利于提高預(yù)拌混凝土的質(zhì)量。整個攪拌筒體是安裝在支架上方的,前部有兩個托輪支撐,攪拌筒體上設(shè)有人孔,便于維修。
Mixer truck is widely used in engineering construction. There are many spare parts on the mixer truck. Under their joint action, the mixer truck can work normally. Let's take a look at the performance of the main spare parts of the mixer truck. The mixing drum is one of the main parts of the mixer truck. The role of the mixing drum is very important. It is closely related to the service life of the mixer truck. The mixing drum is mainly composed of the drum, sealing pipe, blade and other parts. The funnel-shaped sealing pipe can ensure the smooth feeding, and the curved blade is conducive to the discharging performance of the ground slump concrete. There are holes on the blade, which can reduce the pressure Reducing the adhesion of concrete on it is helpful to improve the quality of ready mixed concrete. The whole mixing cylinder is installed above the support, with two supporting wheels at the front. The mixing cylinder is provided with a manhole for easy maintenance.
傳動系統(tǒng)采用的是原車發(fā)動機取力形式,由取力器從發(fā)動機上取力傳送到減速機上并驅(qū)動攪拌罐做正反旋轉(zhuǎn),從而實現(xiàn)進料出料。液壓系統(tǒng)主要是由液壓泵、液壓馬達、減速機等組成,液壓泵上設(shè)有手動伺服調(diào)節(jié)手柄,可以調(diào)節(jié)液壓油的流量及流向,從而控制攪拌罐的轉(zhuǎn)向和轉(zhuǎn)速,攪拌罐的正反轉(zhuǎn)均能無級調(diào)速。
The transmission system adopts the power take-off form of the original vehicle engine. The power take-off device takes the power from the engine and transmits it to the reducer, and drives the mixing tank to rotate forward and backward, so as to realize the feeding and discharging. The hydraulic system is mainly composed of hydraulic pump, hydraulic motor, reducer, etc. the hydraulic pump is equipped with a manual servo control handle, which can adjust the flow and flow direction of hydraulic oil, so as to control the rotation and speed of the mixing tank. The forward and reverse rotation of the mixing tank can be stepless speed regulation.
攪拌一體車的軸承,軸承在正常的使用過程中是慢慢磨損的,但是如果因發(fā)動機的裝配調(diào)整不當(dāng)、潤滑油的品質(zhì)不好或使用條件惡劣等因素致使軸承過早的磨損或者出現(xiàn)各種損傷,則是人為造成的過早損壞,軸承過早損壞的形式有機械損壞、軸承穴蝕、疲勞點蝕、腐蝕等等。機械損傷是指軸瓦的合金表面出現(xiàn)不同程度的溝痕,嚴(yán)重時在接觸面發(fā)生金屬剝離以及出現(xiàn)大面積的雜亂劃傷,一般情況下接觸面損傷與燒油現(xiàn)象同時存在。軸承穴蝕是軸承在氣缸壓力沖擊載荷的反復(fù)作用下,表面層發(fā)生塑性變形和冷作硬化,局部喪失變形能力,逐步形成條紋并不斷擴展,然后隨著磨屑的脫落,在受載表面形成凹穴。如果定位不良,需拆下?lián)Q擋叉軸,檢驗定位球及彈簧。如果齒輪未完全嚙合,用手推動掉檔的齒輪或齒套,能者卻嚙合,應(yīng)檢查換擋叉是否彎曲或者磨損,換擋叉固定螺絲有沒有松動,叉端與齒輪槽間隙是否過大。若是換擋良好,而齒輪或齒套又能完全嚙合時,應(yīng)檢查齒輪是否磨成雛形、軸承是否松曠、變速軸是否前后移動。根據(jù)上述檢查所發(fā)現(xiàn)的問題,按標(biāo)準(zhǔn)修復(fù),必要時需更換新件。
The bearing of the mixer truck is slowly worn in the normal use process, but if the premature wear or various damages of the bearing are caused by improper assembly and adjustment of the engine, poor quality of lubricating oil or bad use conditions, it is the premature damage caused by human. The forms of premature damage of the bearing include mechanical damage, bearing cavitation, fatigue pitting, fatigue pitting, etc Corrosion and so on. Mechanical damage refers to the groove marks on the alloy surface of bearing bush in different degrees. In severe cases, metal peeling occurs on the contact surface and a large area of messy scratch occurs. Generally, the contact surface damage and oil burning exist at the same time. The cavitation erosion of bearing is that the plastic deformation and cold work hardening occur on the surface layer of bearing under the repeated action of cylinder pressure impact load, and the local deformation ability is lost, gradually forming stripes and expanding, and then with the falling off of wear debris, the cavitation is formed on the loaded surface. If the positioning is not good, remove the shift fork shaft and inspect the setting ball and spring. If the gear is not fully meshed and the gear or gear sleeve is pushed by hand, but the gear or gear sleeve can be meshed, check whether the shift fork is bent or worn, whether the fixed screw of the shift fork is loose, and whether the clearance between the fork end and the gear groove is too large. If the gear shift is good and the gear or gear sleeve can be fully meshed, check whether the gear is ground into a rudiment, whether the bearing is loose, and whether the variable speed shaft moves forward and backward. According to the problems found in the above inspection, repair according to the standard, and replace with new parts if necessary.
攪拌一體車攪拌操作桿分布在車輛尾部兩側(cè),它可以控制攪拌車的進料和出料。
The mixing operating rods of the mixer truck are distributed on both sides of the rear of the truck, which can control the feeding and discharging of the mixer truck.
