[0022] In this embodiment, the flatbed vehicle 1, the drive motor 2, the control box 3 and the cleaning brush 51 constitute the main structure of the double-track rail fastener inspection vehicle involved in this application.

[0023] Specifically, the laser displacement sensor 12 and the CCD camera 13 adopt the same device as that involved in the comparative document (application number: 201720533921.3); the driving wheels 14 are provided in two groups, front and rear, on the lower side of the flatbed vehicle 1, and the front group of driving wheels 14 is connected to the half-axle 24, and the rear group is independently connected to the flatbed vehicle 1 for rotation, and the cleaning brush 51 is located in front of the front group of driving wheels 14.

[0024] As a preferred embodiment, the stable movement of the flatbed truck 1 is achieved by setting up two sets of driving wheels 14, and through the rotational connection between the driving wheels 14 and the flatbed truck 1, and the universal connection between the driving wheels 14 and the outer ball cage 25, a natural turn can be achieved at the arc of the track, and the turning force comes from the driving force of the flatbed truck 1 and the force applied by the track to the wheel groove wall of the driving wheel 14; the wheelbase of the driving wheel 14 matches the width of the rail.

[0025] like Figure 1 and Figure 5 As shown, the driving wheel 14 is rotatably connected to the flatbed vehicle 1, and the CCD camera 13 is located on both sides of each driving wheel 14, and the laser displacement sensor 12 is located on the outside of the CCD camera 13, an alarm 32 and an antenna 33 are installed on the upper side of the control box 3, and the alarm 32 is electrically connected to the alarm module set inside the main controller 34, and the laser displacement sensor 12 and the CCD camera 13 are electrically connected to the detection module set inside the main controller 34.

[0026] Specifically, a wireless communication module and a driving module are further provided in the main controller 34 , and the wireless communication module is electrically connected to the external antenna 33 , and the driving module is electrically connected to the external driving motor 2 .

[0027] As a preferred embodiment, during the detection process, when the position of the rail fastener deviates from the actual standard position, the alarm module can drive the alarm 32 to alarm, and at the same time, the main controller 34 and the drive module can stop the drive motor 2, which is convenient for guiding the location of the problem.
