The modified formula for the boom of large complicated bucket wheel excavator has been put forward under earthquake, included the local dynamic effect.
对大型斗轮挖掘机臂架,通过考虑局部动力效应,推导了在地震荷载作用下结构单元的修正公式。
This paper discusses test and determination of the predicting formula for cutting resistance cf coal and rock and be referred to use for design calculation of bucket wheel excavator.
介绍煤岩切割阻力试验和预测公式,以供轮斗挖掘机设计计算使用和参考。
The results indicate that it is feasible to employ bucket wheel excavator for coal mining based on the cutting force analysis.
结果表明,采煤选用轮斗挖掘机从切割力角度分析在技术上是可行的;
Taking WDL950(30/5) bucket wheel excavator as a sample machine , a finite element model of its upper part is established , with its both dynamic and static forces analyses being given.
以WDL950(30/5)型斗轮挖掘机为样机,建立了其上部有限元模型,并对其进行了静动力分析,进而通过动力响应的计算给出了斗轮机主要部位采用不同动力系数的参考值。
However, it is more difficult for bucket wheel excavator to work in overburden stripping than in coal mining, which means that continuous working in the whole year can not be realized.
剥离选用轮斗挖掘机从切割力角度分析难度大于采煤,无法实现全年连续作业。
“Bucket wheel excavator”是一个工程机械领域的专业术语,其含义和结构可通过以下四个层面解析:
术语定义
指一种由旋转轮盘和多个铲斗组成的大型连续挖掘设备,主要用于露天采矿和大规模土方工程。其核心特征是通过轮盘上的连续铲斗实现高效物料采集。
词源解析
应用领域
主要应用于褐煤矿开采、大型水利工程和港口建设,单台设备日挖掘量可达24万立方米,相当于3个标准足球场的土方量。典型案例包括德国Hambach露天煤矿使用的Bagger 288型号。
关键技术参数
斗轮直径、斗容、驱动功率构成三大核心指标。以提到的案例,直径增加10%可使理论生产率提升约15%,但设备重量和造价也会相应增加20%以上。
该设备在《矿山机械术语》(GB/T 7679.3)中被归类为"连续式挖掘装载机",属于超重型工程机械范畴。如需查看具体型号参数,可参考和提供的专业词典内容。
