1.故障现象日照港矿石堆场2台2005年投产的ZC3500型自动装车机,由于其尾车行走轨道出现下陷变形故障,造成作业过程中其整体重心向悬臂头部的分叉漏斗方向偏移(尾车上部最大偏移量约100mm),导致尾车钢结构产生严重变形甚至开裂,设备运行存在较大的安全隐患。ZC3500型自动装车机如图1所示。2.原因分析分析认为,造成装车机尾车钢结构变形、开裂的主要原因有以下3点:一是装车机尾车钢结构原始设计强度偏小,地面胶带输送机对
1. Fault phenomenon Rizhao Port ore yard 2 units put into operation in 2005 ZC3500-type automatic loading machine, due to its trailer walking track sag deformation, resulting in the operation of its overall center of gravity to the cantilever head bifurcated funnel direction deviation (The maximum offset of the tail of the car is about 100mm), resulting in severe deformation and cracking of the steel structure of the tail car. There is a big potential safety hazard in the operation of the equipment. ZC3500 automatic loading machine shown in Figure 1. 2. Analysis and analysis of the reasons that lead to the loading truck tailings steel deformation, cracking the main reason for the following three points: First, loading tail car steel structure design strength of the original small, ground conveyor belt conveyor
