Example

As shown in FIG. 1 and FIG. 2 , a railway track maintenance device proposed by the utility model includes a maintenance vehicle body 1, a running wheel set 7 installed at the bottom of the maintenance vehicle body 1, and a cleaning device;

The cleaning device includes a driving cylinder 4, a connecting bracket 9, a mounting frame 11, a mounting roller 10 and a sanding belt 12. The driving cylinder 4 is fixed to the upper surface of the maintenance vehicle body 1. The connecting bracket 9 is located below the maintenance vehicle body 1 and is fixedly connected to the piston rod end of the driving cylinder 4. The mounting frame 11 is fixed to the bottom of the connecting bracket 9. The mounting roller 10 is rotatably mounted on both ends of the mounting frame 11. The sanding belt 12 is sleeved on the two mounting rollers 10.

When the maintenance vehicle body 1 moves through the walking wheel group 7, the connecting bracket 9 is driven downward by the driving cylinder 4, so that the mounting frame 11 is moved downward, so that the sanding belt 12 is in contact with the surface of the rail. During the movement of the maintenance vehicle body 1, and under the action of the mounting roller 10, the sanding belt 12 can rotate, so that the rust on the surface of the rail can be cleaned.

The railway track maintenance device also includes a driving device 8, which is fixed to the lower surface of the maintenance vehicle body 1, and is used to drive the running wheel set 7 to rotate so that the device can run along the track. The driving device 8 drives the running wheel set 7 to rotate, so that the device can run along the track, thereby realizing electric running.

The sanding belt 12 is arranged between the running wheel groups 7, and the sanding belt 12 is located just above the track. The sanding belt 12 is arranged just above the track so that the sanding belt 12 can contact the rail when it descends, thereby performing surface treatment on the rail.

The driving cylinder 4 is used to drive the connecting bracket 9 to move up and down, so as to make the grinding belt 12 contact with the upper surface of the track.

It also includes an oiling device, which includes a maintenance oil machine 2 fixed to the upper surface of the maintenance vehicle body 1 and a flat-mouth nozzle 6 fixed to the lower surface of the maintenance vehicle body 1.
