[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 6 According to an embodiment of the utility model, an asphalt grouting device for road maintenance includes a fixed rod 10, on which are disposed two connecting plates 11 which are symmetrical and can slide left and right, a profile frame 12 is disposed at the lower end of the connecting plate 11, and sliding grooves 18 are provided at both left and right ends of the profile frame 12, and the connecting plate 11 and the sliding groove 18 are arranged in a T-shaped sliding fit, a sliding block 14 is slidably connected to the fixed rod 10, and connecting tubes 13 are fixedly disposed at both left and right ends of the sliding block 14, and the connecting tube 13 is fixedly connected to the connecting plate 11, and an insertion rod 15 is fixedly disposed at the lower end of the sliding block 14, and a sliding rod 16 which can slide up and down is disposed at the lower end of the insertion rod 15, and the insertion rod 16 can slide up and down. A spring is connected between 15 and the sliding rod 16, and the lower end of the sliding rod 16 is rotatably connected to the cam 17. An asphalt spray pipe is provided at the upper end of the contour frame 12. A connecting frame 19 is fixedly provided at the rear ends of the two connecting plates 11, and a threaded positioning rod 20 is threadedly connected to the connecting frame 19. Two groups of left-right symmetrical spring telescopic rods 23 are connected between the lower end of the connecting frame 19 and the contour frame 12. Two left-right symmetrical guide plates 21 with their lower ends close to each other and inclined are fixedly provided in the contour frame 12. A leveling strip 24 flush with the lower end surface of the contour frame 12 is clamped at the lower ends of the two guide plates 21, and an insulating block 22 is provided between the ends of the two guide plates 21 that are away from each other and the fixed rod 10.

[0022] This program has the following working process:

[0023] The fixed rod 10 is fixedly installed at the moving end. The sliding rod 16 at the lower end of the insertion rod 15 slides downward at the road gap under the thrust of the spring, so that the lower end of the sliding rod 16 abuts against the road surface. The cam 17 connected to the lower end of the sliding rod 16 is inserted into the gap. In the overall movement process, the cam 17 slides left and right along the track at the gap, thereby driving the sliding block 14 connected to the upper end to slide left and right. Then, under the fixed connection between the sliding block 14, the connecting tube 13 and the connecting plate 11, the contour frame 12 sliding up and down at the lower end of the connecting plate 11 slides left and right synchronously, thereby ensuring that the contour frame 12 moves along the gap track.

[0024] The user inserts the asphalt nozzle into the connecting frame 19 with the nozzle facing downward, and rotates the threaded positioning rod 20 through the threaded connection, so that the inner end of the threaded positioning rod 20 abuts against the outer peripheral surface of the asphalt nozzle, so as to clamp the asphalt nozzle;

[0025] The connecting frame 19 is fixedly arranged on the connecting plate 11 and moves synchronously with the connecting plate 11. Two groups of left-right symmetrical spring telescopic rods 23 are connected between the lower end of the connecting frame 19 and the upper end of the contour frame 12. The spring telescopic rods 23 wrap around the contour frame 12 and the connecting frame 19 to stabilize the connection. The push springs on the outer periphery of the spring telescopic rods 23 apply a downward push to the contour frame 12, so that the lower end of the contour frame 12 fits with the road surface.

[0026] During operation, high-temperature asphalt is sprayed downward through the asphalt nozzle, and under the guidance of the two inclined guide plates 21 on the left and right, the asphalt flows to the middle position of the contour frame 12 (also the rear end part of the cam 17). During the movement of the contour frame 12, the asphalt in the two guide plates 21 is insulated by the insulation blocks 22, and during the forward movement of the contour frame 12, the asphalt laid in the gap is leveled by the leveling strips 24.

[0027] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
