The inside of the liquid storage box 20 is filled with fluorescent pigment without corrosiveness, when the fluorescent pigment is used, the first roller 3 and the second roller 5 at the bottom of the supporting plate 1 are in contact with the ground at two sides of the track, when the painting roller 27 is in contact with the track, the track pushes the painting roller 27 to ascend, the painting roller 27 can drive the second sliding block 38 to slide upwards in the second sliding groove 37 and drive the liquid guide box 26 to move upwards when ascending, the liquid guide box 26 can enable the first sealing block 25 to be separated from the second groove 24 at the top of the guide pipe 21 when moving, so that the pigment in the liquid storage box 20 can be conveyed to the inside of the liquid guide box 26 through the guide pipe 21, the pigment in the liquid guide box 26 is conveyed to the inside of the liquid guide cavity 29 through the through hole 30, the pigment in the liquid guide cavity 29 is conveyed to the inside of the painting roller 27, the second supporting rod 32 on the painting roller 27 is retracted to the inside of the painting roller 27 under the jacking of the, the second sealing block 33 is separated from the inner wall of the painting roller 27, paint can be coated on the top of the track contacted with the painting roller 27 through the paint hole 31, when the height of one track is lower, the second support rod 32 is not subjected to jacking force, the second sealing block 33 seals the paint hole 31 under the action of the elastic force of the first spring 34, so that the height difference between the tracks is identified, the third rotating shaft 11 is rotated, the third rotating shaft 11 can drive the large gear 13 to rotate, the large gear 13 can drive the two meshed small gears 15 to rotate when rotating, the small gears 15 can adjust the height of the first slider 7 on the support plate 1 when rotating, and the height of the clamping block 16 can be adjusted in real time when clamping the tracks by the clamping block 16.

The invention has the beneficial effects that:

(1) according to the track spacing fine adjustment device for urban rail transit, the device can be conveniently moved through the four idler wheels at the bottoms of the two support plates, so that the device is more convenient and labor-saving when used, the second lead screw between the two support plates can drive the two clamping blocks to move oppositely when rotating, the track spacing can be adjusted, the large gear can be driven to rotate through the third rotating shaft, the large gear can drive the two meshed small gears to rotate when rotating, the small gears can adjust the height of the first sliding block on the support plates when rotating, and the height of the clamping blocks can be adjusted in real time when the clamping blocks clamp the track.

(2) According to the track spacing fine adjustment device for urban rail transit, the painting roller is arranged between the two support plates, the first roller can drive the fourth rotating shaft to rotate through the transmission belt and the transmission wheel when rotating, the fourth rotating shaft can drive the painting roller to paint a layer of fluorescent pigment on the top of the track when rotating, the second sliding block can push the painting roller to move downwards under the action of the elastic force of the first spring, the painting roller is in contact with the higher track of the two tracks, so that the fluorescent pigment is painted on the top of the higher track, namely the track without the paint is lower than the other track, and the height difference between the two tracks can be detected conveniently.

(3) According to the track spacing fine adjustment device for urban rail transit, the first sealing block is arranged, when the coating roller does not contact with a rail, the first sealing block can seal the guide pipe, so that pigment cannot be conveyed into the coating roller, and the coating roller is positioned at the position where the rail contacts and can push the second sealing block to seal a coating hole at the position where the rail does not contact under the action of the elastic force of the first spring, so that errors caused by the fact that the pigment in the coating roller drops on the rail can be effectively prevented.
