[0002] Asphalt paving is the process of paving asphalt mixture evenly and smoothly on the road base. This process is mainly used for road construction and maintenance and is an important part of road construction. The quality of asphalt paving directly affects the service life and driving safety of the road. Therefore, during the construction process, the quality and technical requirements of each link must be strictly controlled to ensure that the paved road is flat, durable and safe. At the same time, it is also necessary to select the appropriate asphalt type and paving process according to specific engineering conditions and design requirements to meet different road use needs.

[0039] Example 1

[0040] This embodiment provides a municipal road asphalt paving device, such as Figure 1As shown, it includes a main frame 1, a plurality of rollers 10 are rotatably connected to the bottom of the main frame 1, and a storage tank 3 is arranged on the top of the main frame 1.

[0041] like Figure 2 and Figure 4 As shown, a laying mechanism is arranged on the side of the main frame 1, and the laying mechanism includes a spray gun 6, a delivery pump 7, a receiving frame 8, a nozzle 9 and a delivery pipe 20. The delivery pump 7 is fixedly installed on the top of the main frame 1, and the delivery pipe 20 is fixedly installed between the delivery pump 7 and the storage tank 3. The spray gun 6 is connected to both sides of the delivery pump 7 through a hose, and the asphalt material prepared and loaded in the storage tank 3 is introduced into the municipal road that needs to be repaired through the spray gun 6, and the asphalt material loaded in the storage tank 3 is filled in the gaps or potholes in the municipal road.

[0042] A receiving frame 8 is fixedly installed on one side of the side wall of the main frame 1, and a plurality of spray pipes 9 are fixedly installed on the bottom of the receiving frame 8, and the receiving frame 8 is connected to the delivery pump 7. The plurality of spray pipes 9 are moved, and the asphalt material inside the storage tank 3 is evenly sprayed on the municipal road at the repairing location through the plurality of spray pipes 9.

[0043] Several nozzles 9 are distributed equidistantly in a straight line along the receiving frame 8, and the length of the receiving frame 8 is smaller than the distance between the two rollers 10. It is prevented that the rollers 10 are directly pressed on the asphalt and leave marks.

[0044] The tail of the main frame 1 is provided with a tamping mechanism, which includes a connecting frame 11, a tamping roller 12 and a sleeve frame 13. The two sides of the main frame 1 are rotatably connected to the two connecting frames 11, the connecting frame 11 is rotatably connected to the sleeve frame 13, and the end of the sleeve frame 13 is rotatably connected to the tamping roller 12.

[0045] like Figure 3 As shown, a support frame 15 is fixedly provided at the bottom of the main frame 1, a hydraulic cylinder 16 is fixedly provided on the support frame 15, a sliding frame 14 is rotatably provided at the output end of the hydraulic cylinder 16, and the sliding frame 14 is limitedly slidable on the connecting frame 11.

[0046] like Figure 7 As shown, the support frame 15 is lowered by retracting the hydraulic cylinder 16, and the sliding frame 14 acts as an intermediate piece to prevent the support frame 15 from being stuck. Then the sleeve frame 13 moves downward, and the tamping roller 12 is lowered and rolled to be placed on the municipal road. The tamping roller 12 is then rolled repeatedly to roll and compact the asphalt material on the municipal road.

[0047] In this embodiment, the main frame 1 is moved to move the nozzle 9, and several nozzles 9 evenly spray the asphalt in the storage tank 3 onto the municipal road at the repair site. The spray gun 6 fills the gaps or potholes in the municipal road that cannot be covered by the sprinkler 9, thereby improving the paving efficiency.

[0048] Example 2

[0049] Based on Example 1, this embodiment proposes a municipal road asphalt paving device, such as Figure 4 and Figure 5 As shown, a material storage mechanism is arranged inside the material storage tank 3, and the material storage mechanism includes a rotating ring 17, a mounting frame 19 and a rotating circle 21. Several mounting frames 19 are fixedly installed on the top of the main frame 1, and several rotating rings 17 are fixedly arranged between the several mounting frames 19. The rotating circle 21 is rotatably arranged in the inner wall of the rotating ring 17, and several rotating circles 21 are rotatably arranged on the outer wall of the material storage tank 3.

[0050] The material storage tank 3 is supported by the mounting frame 19 , and the friction force is reduced by the cooperation between the rotating ring 17 and the rotating circle 21 , so that the material storage tank 3 can rotate.

[0051] like Figure 6 As shown, the storage mechanism also includes a heating shaft 24 rotatably arranged at the middle position inside the storage tank 3, and a plurality of stirring shafts 23 are fixedly arranged on the inner wall of the storage tank 3. The stirring shafts 23 protrude from the inner wall of the storage tank 3, and the stirring shafts 23 are in contact with the asphalt in the storage tank 3.

[0052] The asphalt material loaded in the storage tank 3 is heated by the heating shaft 24 to prevent the asphalt from solidifying. At the same time, when the storage tank 3 rotates, the asphalt therein continuously changes position to prevent the asphalt from precipitating and adhering to the inner wall of the storage tank 3. The asphalt collides with the stirring shaft 23 to break and separate the solidified part of the asphalt.

[0053] A battery 5 is fixedly installed inside the main frame 1 , an electric conductor 2 is fixedly connected between one end of the storage tank 3 and the battery 5 , and the battery 5 supplies power to the motor 4 .

[0054] The drive mechanism also includes a motor 4, a drive belt 18 and a drive ring 22. The motor 4 is fixedly installed on the top of the main frame 1, and the drive ring 22 is fixedly installed at the middle position of the outer wall of the storage tank 3. The output end of the motor 4 and the drive ring 22 are transmitted through the drive belt 18. The motor 4 provides a rotational force to the drive ring 22, so that the storage tank 3 rotates.

[0055] In this embodiment, the asphalt is insulated by the storage tank 3 to prevent solidification, and the heating shaft 24 heats the asphalt material loaded in the storage tank 3. At the same time, the storage tank 3 rotates, and the asphalt therein continuously changes position to prevent the asphalt from precipitating and adhering to the inner wall of the storage tank 3. The collision of the asphalt with the stirring shaft 23 not only generates heat, but also breaks up the gathered asphalt for separation, thereby preventing the asphalt from clumping.

[0056] A municipal road asphalt paving method is applied to the above-mentioned municipal road asphalt paving device, and the steps are as follows:

[0057] S1. The asphalt repair material is heated and prepared, and then the prepared asphalt material is introduced into the interior of the storage tank 3, and the heating shaft 24 is started to heat the asphalt material loaded in the storage tank 3;

[0058] S2. Clean municipal roads that need asphalt repairs, and remove dirt and other debris from cracks or potholes in the road surface;
