全断面隧道掘进机(TBM)作为目前隧道施工的先进设备已经得到成功应用并受到广泛关注,其核心部件主轴承决定着主机的使用寿命,在使用过程中主轴承的管理、维护和故障处理尤为重要。结合新疆吐库二线中天山隧道施工中使用的TB880E型敞开式全断面隧道掘进机主轴承出现的故障,分析其发生的原因、梳理由简到繁的故障可能因素、介绍采取的修复措施和成功排除故障的经验,提出了TBM主轴承的综合监测方案,可作为提高TBM设备完好率和利用率的参考依据。
Full-face tunnel boring machine (TBM) as the current tunnel construction of advanced equipment has been successfully applied and received widespread attention, the core components of the main bearing determines the life of the host during use, the main bearing management, maintenance and troubleshooting is particularly important. Combined with the failure of main bearing of TB880E open full face tunnel boring machine used in the construction of Tiantu Second Middle Tianshan Tunnel in Xinjiang, the paper analyzes the reasons for the occurrence, analyzes the possible causes of faults from simple to complex, introduces the repair measures and success Troubleshooting experience, put forward a comprehensive monitoring program of TBM main bearing can be used as a reference to improve the intact rate and utilization of TBM equipment.
