The probe loading arm comprises a loading arm mounting plate, a vertical slide rail assembly and a probe bracket; the vertical sliding rail component is formed by installing a rotating shaft connecting block, a vertical sliding rail and a tension spring mounting block together; the probe bracket is connected with the rotating shaft connecting block through a horizontal rotating seat and a rotating shaft at the lower end of the rotating shaft connecting block, and a probe bracket locking screw is arranged on the horizontal rotating seat; a vertical slide rail on the vertical slide rail component is connected with a vertical slide rail seat on the vertical slide rail mounting plate; a probe pressing tension spring is arranged between the tension spring mounting block and the vertical slide rail mounting plate; the vertical slide rail mounting plate is connected with a horizontal slide rail on the loading arm mounting plate through a horizontal slide rail seat; the loading arm mounting plate is connected with the machine shell.
A main driving wheel and a driven wheel in the straddle type shell are in contact with the rail surface of the detected steel rail, and the main driving wheel is a magnetic wheel. The ultrasonic probe is arranged on the probe bracket; the casing is provided with a remote control device inside.
When the scanning machine works, the scanning machine is straddled on the steel rail to be detected, and the ultrasonic probe is contacted with the surface of the steel rail. The probe pressing tension spring pulls the vertical sliding rail component downwards, so that the ultrasonic probe has proper contact pressure on the steel rail. When the ultrasonic probe forms a certain included angle with the steel rail according to the requirements of the ultrasonic process, the ultrasonic probe can be adjusted through the horizontal rotating seat and locked by the locking screw of the probe bracket. When the central line of the ultrasonic probe deviates a certain value from the central line of the steel rail according to the requirements of the ultrasonic process, the vertical slide rail mounting plate can be horizontally moved, and the locking screw is horizontally moved to be tightened, so that the ultrasonic scanning operation on the steel rail can be carried out.
