The first auxiliary wheel 8 assists the moving wheel 6 to make the movement of the track inspection vehicle more stable. A limiting component for limiting the movement of the support frame 1 is installed on one side of the outer wall of the support frame 1.

[0026] The limiting component includes a limiting rod 9. One end of the limiting rod 9 is fixedly connected to one side of the outer wall of the support frame 1. The limiting rod 9 provides a guiding function for the movement of the sliding plate 10. A sliding plate 10 is slidably connected to the outer wall of the limiting rod 9. The sliding plate 10 can move along the limiting rod 9 under the action of the moving screw rod 11. The moving screw rod 11 is internally threaded in the sliding plate 10. One end of the moving screw rod 11 is rotatably connected to one side of the outer wall of the support frame 1. The rotation of the moving screw rod 11 can drive the sliding plate 10 to move. One side of the outer wall of the sliding plate 10 is fixedly connected to an extension rod 13. The extension rod 13 is used to install the second auxiliary wheel 14 and enable it to move to a suitable position. The second auxiliary wheel 14 is rotatably connected to the outer wall of the extension rod 13. The second auxiliary wheel 14 cooperates with the moving wheel 6 and the first auxiliary wheel 8 to further improve the stability of the track inspection vehicle and limit its movement.

[0027] Referring to Figure 1 , Figure 3 and Figure 4, a fixing block 15 is fixedly connected inside the support frame 1. The fixing block 15 serves to support and connect the hinge seat 16. An upper surface of the fixing block 15 is fixedly connected with the hinge seat 16. The hinge seat 16 provides a position for rotational connection of the hinge block 17.

The clamping blocks 26 are used to clamp the recorder 4 to ensure the stability of the recorder 4 during the detection process. An anti-slip pad 27 is fixedly connected inside the clamping block 26. The anti-slip pad 27 increases the friction between the connecting frame 3 and the clamping block 26, further improving the stability of the recorder 4. A knob one 12 is fixedly connected to one side of the outer wall of the moving lead screw 11. The knob one 12 is used to drive the moving lead screw 11 to rotate, facilitating the operator to adjust the limiting component. One end of the bidirectional lead screw 24 is fixedly connected with a knob two 25. The knob two 25 is used to drive the bidirectional lead screw 24 to rotate, facilitating the operation of the clamping component.

[0028] Working principle: When it is necessary to detect the track, first place the moving wheel 6 on the track. Then, rotate the first knob 12. At this time, the first knob 12 drives the moving lead screw 11 to rotate on one side of the support frame 1. Then, the moving lead screw 11 drives the sliding plate 10 to move in a limited way on the outer wall of the limiting rod 9. Then, through the movement of the sliding plate 10, the outer wall of the extension rod 13 is closely attached to the side of the track. At this time, through the cooperation of the first auxiliary wheel 8 and the second auxiliary wheel 14, the effect of stabilizing the support frame 1 on the outer wall of the track is achieved. At the same time, by pushing the connecting frame 3, the effect of moving the support frame 1 on the outer wall of the track is achieved. At the same time, through the cooperation of the detector 2 and the recorder 4, the effect of facilitating the recording and measurement of the track conditions is achieved;

[0029] Secondly, when installing and fixing the recorder 4, place the recorder 4 above the support plate 21. Then, rotate the second knob 25. At this time, the second knob 25 drives the clamping block 26 on the outer wall of the bidirectional lead screw 24 to slide in a limited way on the outer wall of the limiting column 23. Then, the clamping block 26 drives the anti-slip pad 27 to clamp on the outer wall of the connecting frame 3, thus achieving the effect of stabilizing the connecting frame 3. At this time, according to the usage requirements, rotate the nut 19. By rotating the connecting frame 3, the hinge block 17 is driven to rotate, and then the effect of driving the angle adjustment of the recorder 4 is realized.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
