The embodiment of the invention discloses a train surface crack detection system which is characterized in that in a base, a left-right moving mechanism is arranged on a base body; a first telescopic rod is arranged on the base body in a foldable mode. A second telescopic rod is arranged on the left-right moving mechanism in a foldable mode. In a sensor probe support arm mechanism, a plurality of supporting rod assemblies are connected through a first rotary connection mechanism at the X-shaped connection part of a shear fork structure. The multiple supporting rod assemblies are connected through second rotating connecting mechanisms at the V-shaped connecting positions of the shear fork structure. The first telescopic rod and the second telescopic rod are connected to the X-shaped connecting positions respectively. An acoustic emission probe servo device is movably arranged on the supporting rod assembly. According to the train surface crack detection system, acoustic emission sensors can be rapidly and accurately arranged, the accurate positioning of cracks can be achieved, and the problems that a conventional magnetic probe cannot play a role in supporting, the sensors cannot be well attached to the surface of a train body, and large-area probe arrangement is large in difficulty and low in efficiency, the adjustment is difficult, the relative position of a probe is difficult to accurately and quickly obtain are solved.
Description
technical field [0001] The present application relates to the relevant technical field of train surface crack detection, in particular to a train surface crack detection system. Background technique [0002] With the continuous increase in the operating mileage of high-speed railways in my country, the number of high-speed trains has increased, and the demand for maintenance and repair of EMU trains related to operational safety has risen. With the continuous expansion of the maintenance market demand, the periodic maintenance strategy adopted at present has highlighted the problems of over-maintenance and under-maintenance due to the lack of actual condition detection. Insufficient grasp of vehicle status and zero tolerance for problems found, the replacement cycle of parts is short and the operating cost is high. [0003] Using more sensitive and efficient sensing methods, fully combining modern signal analysis methods to monitor the health status of high-speed trains and...
