Railway hook body flaw detector
该设备为机电分开式，是专门适用于铁路列车提速，确保列车在重载、高速运行的安全，根据铁道部对列车钩体磁粉探伤要求而设计。设备具有单机工作和配合流水线检测的功能，单机工作配备水平平台架式上料机构，自动进位，设备采用复合磁化法、周向通电法、纵向采用新型磁轭装置，对钩颈、下锁孔筋、勾舌圆弧面进行复合磁化，由于受磁路的影响钩耳采用穿棒法，实现了三路磁化，全方位显示，借助荧光的作用，能清晰的显示任意方向的各种裂纹缺陷。全过程采用PLC控制，具有结构合理、操作方便、自动化程度高，检测灵敏度优等特点。
The equipment is electromechanical and is specially suitable for the speed increase of railway trains to ensure the safety of heavy load and high speed operation. It is designed according to the requirements of the Ministry of Railways for magnetic particle inspection of train hook bodies. The equipment has the functions of single-machine operation and assembly line detection. The single-machine operation is equipped with a horizontal platform rack feeding mechanism, which carries automatically. The equipment adopts composite magnetization method, circumferential energization method and longitudinal adoption of a new type of magnetic yoke device. The hook neck, lower lock hole rib and hook tongue arc surface are subjected to composite magnetization. Due to the influence of magnetic circuit, the hook ear adopts rod threading method, which realizes three-way magnetization and all-round display. With the help of fluorescence, various crack defects in any direction can be clearly displayed. The whole process is controlled by PLC, featuring reasonable structure, convenient operation, high degree of automation and excellent detection sensitivity.
