The job step of this rail surface detection apparatus is following:
Detect beginning, (this motion can be that pick-up unit is fixed on the Rail Production line, and rail moves on production line along rail bearing of trend generation relative motion for rail and this device; Also can be that this device is fixed on the detection dolly, rail be motionless, detects dolly and moves along rail; Can also be to detect on the train, train orbits);
The imageing sensor that is positioned at the pick-up unit front end obtains the picture signal on rail surface, transfers to data processing and output unit;
The surface smoothness cell pressure that is positioned at the pick-up unit middle part detects and utilizes the data variation of sensor in the subtle change generation of rail pressure, detects the smooth situation on rail surface, and signal transfers to data processing and output unit; The surface smoothness sensor metal Density Detection that is positioned at the pick-up unit rear portion is utilized the data variation of sensor in the subtle change generation of rail density, detects the smooth situation on rail surface, and signal transfers to data processing and output unit;
Data processing and output unit receive the view data of imageing sensor, and the pressure of surface smoothness sensor and density metal data are carried out data processing and comparison; Analysis-by-synthesis obtains the rail surface and detects conclusion, writes down all and detects data; Quality flaw position, the positional information that the binding site register provides, record position, picture, pressure data, density data are detected in the rail surface; And after detecting end, can concentrate output.
Use the utility model; The rail surface is detected; Can accomplish the detection task automatically, the data message of rail surface blemish is provided, a reliable detection method is provided the quality testing robotization of rail; The manual working intensity that reduces range estimation detection in the past is random with detection, strengthens the science and the preciseness of quality detection work.
