[0039] Working principle: When the cart 4 is used in conjunction with the caulking machine 1 to repair the cracks in the road through the caulking pipe rod 5 during road maintenance, asphalt or hot-melt rubber is usually placed in the heating barrel on the caulking machine 1 to be heated to a liquid state. When one end of the caulking pipe rod 5 is brought close to the road gap, the air duct 23 on the outer surface will be driven close to the road gap and inserted into it, which will drive one side of the adsorption cover 253 to stick to the surface of the road.

Therefore, there is no fixed limitation. The auxiliary mechanism 25 can perform preliminary cleaning on the inside of the road gap to facilitate the subsequent grouting process. At the same time, the air pump 22 is started to suck the external air into the hollow frame 21, and then blow it to the inside of the road gap through the air duct 23 to blow away the dust and impurities to achieve the cleaning effect. At the same time, the auxiliary mechanism 25 is also used for preliminary cleaning. In this way, during the grouting process, the grouting material can flow normally into the gap and fully contact the gap wall to avoid uneven grouting or incomplete filling of some areas, thereby improving the repair quality and repair service life. Then the pumping system on the grouting machine 1 is started to inject liquid asphalt or hot-melt rubber into the road gap through the grouting pipe rod 5, and the cart 4 is pushed to cooperate in repairing the gap.

[0040] When the cleaning device 2 is not in use, or according to the depth of the gap in the road, first hold the operating block 39 and press it inwardly to a certain position in the inner wall of the rectangular block 33 so that one side of it abuts against one end of the pushing block 38, and slide it to one end in the inner wall of the slide hole 36 to shrink the second spring 37, and then sleeve the rectangular block 33 on the outer surface of the caulking pipe rod 5 through the two elastic blocks 34 so that the slide rail 31 is inserted into the inner wall of the rectangular groove 35. At this time, release the operating block 39, and under the reset action of the second spring 37, the One end of the clamping block 38 is inserted into the inner wall of the clamping hole 32, so that the hollow frame 21 and the rectangular block 33 can be fixedly installed on the outer surface of the caulking pipe rod 5. Then, according to the use requirements, the operating block 39 can be pressed again to pull one end of the clamping block 38 out of the clamping hole 32, and then with the help of the elastic block 34, it can slide to both ends on the outer surface of the caulking pipe rod 5 and the slide rail 31, so that the depth of the air duct 23 inserted into the road gap can be adjusted, which is convenient for the use of the cleaning device 2.
