摘要
针对门座式起重机象鼻梁开展局部改造设计,以便提升起升高度,延长使用年限.文章简要分析了门座式起重机的适用范围和结构特征,并围绕传统象鼻梁卸扣连接模式、滑轮组样式、箱型梁结构提出局部改造设计建议,依靠构建仿真分析模型、客观评估疲劳寿命、设置性能测试实验等方法,创造有利的局部改造设计条件,保证象鼻梁门座式起重机设备改造后满足安全运行要求.
Abstract
In order to raise the lifting height and prolong the service life,the gantry crane's elephant nose beam is partially modified and designed.This paper briefly analyzes the scope of application and structural characteristics of gantry crane,and puts forward some suggestions for local transformation design based on the traditional trunk beam shackle connection mode,pulley block style and box beam structure,and creates favorable local transformation design conditions by constructing simulation analysis model,objectively evaluating fatigue life and setting performance test experiments.Ensure that the gantry crane with elephant nose beam can meet the safety operation requirements after the renovation.
