[0033] Working principle: First, the railway track maintenance device realizes the convenient movement of the maintenance device through the pulleys arranged on the outer wall of the bottom end of the vehicle frame 1. After starting the motor 6, the output shaft of the motor 6 drives the first rotating shaft 14 to rotate, and then the first gear 15 fixedly connected to the first rotating shaft 14 rotates. The rotation of the first gear 15 drives the first toothed plate 16 engaged with it to move. The connecting frame 4 fixed to the outer wall of the right end of the first toothed plate 16 moves accordingly, and the painting box 3 fixed to the outer wall of the front end of the connecting frame 4 also moves. At the same time, the movement of the first toothed plate 16 also drives the second gear 17 engaged with it to rotate, and the second gear 17 drives the second toothed plate 2 engaged with it to move. During the painting process, by starting the motor 6, the front outer wall of the brush plate 19 contacts the side of the track. The oil pump 8 works, extracts the maintenance oil in the fuel tank 7 through the first oil pipeline 9, and transports it to the brush plate 19 through the second oil pipeline 5. When the brush plate 19 contacts the track, it will move into the painting box 3 under extrusion and compress the first spring 20, thereby realizing the application of the maintenance oil on the track. For the adjustment component, when it is necessary to adjust the height of the handrail 10, pull out the insert block 12 outward to make the rear outer wall of the insert block 12 leave the front inner wall of the handrail 10, releasing the fixation of the handrail 10. After adjusting the height of the handrail 10, release the insert block 12. Under the action of the second spring 11, the insert block 12 is clamped on the front inner wall of the handrail 10 to fix the position of the handrail 10.

[0034] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
