伸缩岸边集装箱起重机大梁焊接轨道的研究

Research on telescopic girder welding rail of quayside container crane

轨道的固定装置是起重机能否在轨道上安全运行的保障,而轨道的固定则完全靠轨道压板或焊缝固定钢轨。超大型起重小车焊接型轨道经常由于贴合度难以达到要求,在长期使用后出现开裂现象。文中针对此问题结合实际分析,采用环氧树脂灌浆的方式有效解决了焊接轨道开裂的问题,对焊接型轨道在起重机小车轨道方面的推广有很好的指导意义。

The rail fixing device can ensure crane＇s safety operation,while its fixture depends on the track holddown plate or weld joint fixing the rail.Due to the fitting degree of welded track failing to meet the requirements,cracks may occur on certain welding rail of extra-large lifting trolley after long-term service.Aiming at this problem and considering actual analysis,the epoxy resin grouting method is adopted for effectively solving the problems in cracks of welding rails, which provides excellent guidance for promotion of welding rails in the crane＇s trolley track.
