The invention discloses orthotropic steel bridge deck fatigue crack detection equipment which comprises a walking assembly and a detection platform assembly, the walking assembly comprises a driving walking mechanism, a driven walking mechanism and a third driving mechanism, and the driving walking mechanism and the driven walking mechanism are each of an arc-shaped structure; electromagnets are arranged at the tops of the two ends of the driving walking mechanism and the driven walking mechanism, a transmission shaft of the third driving mechanism penetrates through the driven walking mechanism and then is in threaded connection with the driving walking mechanism, and when the third driving mechanism drives the transmission shaft to rotate, the driving walking mechanism can get close to or get away from the driven walking mechanism. The orthotropic plate fatigue crack is automatically detected by carrying a phased array ultrasonic detector, meanwhile, in the moving process of the orthotropic plate fatigue crack on the orthotropic steel bridge deck, the vibration of the equipment can be reduced, and the detection accuracy is improved.
本发明公开了一种正交异性钢桥面板疲劳裂纹检测装备,包括行走组件和检测平台组件,所述行走组件包括主动行走机构、被动行走机构以及第三驱动机构,所述主动行走机构和被动行走机构均为弧形结构,并且主动行走机构和被动行走机构两端顶部均设有电磁铁,所述第三驱动机构的传动轴贯穿被动行走机构后与主动行走机构螺纹连接,当第三驱动机构带动传动轴转动时,主动行走机构能够向着被动行走机构靠拢或远离。本发明通过携带相控阵超声波检测仪实现对正交异性板疲劳裂纹的自动检测,同时在正交异性钢桥面上移动的过程中,能够减小本装备的震动,提高检测的精准度。
