本公司2台双梁桥式抓斗起重机运行几年后先后出现大、小啃轨现象,运行时发出“咚咚”的撞击声。对此异常现象,笔者根据车轮磨损情况和轨道情况,更换了车轮并对车轮轮距及对角线进行调校,运行一段时间后,此故障二次出现,通过分析认为可能是起重机桥架发生的变形。桥架是起重机金属结构中最主要的受力构件,由2
After several years of operation, the two double-girder bridge grab cranes of the Company have successively appeared the phenomena of large and small gnawing rails, and issued “pounding” percussion sound during operation. This anomaly, the author according to the wheel wear and track conditions, the replacement of the wheel and wheel alignment and diagonal adjustment, run for a period of time, the fault appears twice, through the analysis that may occur crane bridge Deformation. The bridge is the most important force component in the crane’s metal structure
