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.
