[0022] As Figure 1 , Figure 2 , Figure 3 shown, a pavement repair device for municipal construction projects includes: a vehicle frame 8, with support wheels and universal wheels provided at the bottom of the vehicle frame 8, facilitating the overall movement of the pavement repair device through the support wheels and universal wheels. A heating tank 1 and a pump 7 are fixed on the vehicle frame 8; the heating tank 1 has a double-layer structure, that is, it includes an inner layer and an outer layer, and the gap between the inner layer and the outer layer is an interlayer. A liquefied gas stove 16 for heating the material (asphalt raw material) in the inner tank (inner layer) is provided in the interlayer of the heating tank 1. Ventilation holes are provided on the outer wall of the heating tank 1, and the liquefied gas stove 16 is ventilated through the ventilation holes during operation; the inlet of the pump 7 is connected to the outlet of the inner tank of the heating tank 1, the outlet of the pump 7 is connected to a discharge pipe 11, and a discharge valve 12 is provided on the discharge pipe 11. The pump 7 is electrically connected to a power source. When the pump 7 is turned on, the pump 7 can suck out the asphalt raw material in the inner tank of the heating tank 1 and pump it into the discharge pipe 11. By opening the discharge valve 12, the asphalt raw material can be discharged through the discharge pipe 11; a limit sleeve 6 for fixing and limiting a liquefied natural gas tank 13 is provided on the pump 7. A plurality of rubber limit blocks 17 are provided on the inner ring side surface of the limit sleeve 6. The rubber limit blocks 17 can stably clamp the liquefied natural gas tank 13 inside the limit sleeve 6, ensuring the stability of the liquefied natural gas tank 13 and thus reducing potential safety hazards. The liquefied natural gas tank 13 is connected to the liquefied gas stove 16 through a pipeline, and the liquefied natural gas tank 13 can continuously supply liquefied natural gas to the liquefied gas stove 16 so that the liquefied gas stove 16 can heat the asphalt raw material in the inner tank of the heating tank 1.
[0023] Example 2
[0024] As Figure 1 , Figure 2 shown, this example is a further improvement on Example 1, specifically as follows:
[0025] A fixed cover plate covering a partial area of the tank opening is provided at the top of the heating tank 1. A flip cover plate 2 is provided in other areas of the tank opening at the top of the heating tank 1. The flip cover plate 2 is hinged to the fixed cover plate through a hinge. By opening the flip cover plate 2, raw materials can be added into the inner tank of the heating tank 1. The cooperation of the fixed cover plate and the flip cover plate 2 can minimize heat dissipation.
[0026] Example 3
[0027] As Figure 1 , Figure 2 shown, this example is a further improvement on Example 2, specifically as follows:
[0028] A rotating shaft 14 is arranged in the inner tank of the heating tank 1. A stirring roller 15 is provided on the rotating shaft 14. A right-angle reducer 3 and a motor 4 are provided on the fixed cover plate. The upper end of the rotating shaft 14 is fixed to the output end of the right-angle reducer 3, and the main shaft of the motor 4 is fixed to the input end of the right-angle reducer 3. The motor 4 is electrically connected to the power supply. When the motor 4 is turned on, the motor 4 will drive the right-angle reducer 3 to work. When the right-angle reducer 3 starts to work, the right-angle reducer 3 will drive the rotating shaft 14 to rotate axially in the inner tank of the heating tank 1, and the stirring roller 15 will rotate following the rotating shaft 14, thereby stirring the asphalt raw material in the inner tank of the heating tank 1 to ensure the heating effect of the asphalt.
[0029] Embodiment 4

[0032] Embodiment 5
[0033] As Figure 1 shown, this embodiment is a further improvement based on Embodiment 2 or 3 or 4, specifically as follows:
[0034] A handrail 9 is provided on one side of the vehicle frame 8, which is convenient for applying force to push the entire road surface repair device to move. In addition, a control board 10 electrically connected to the pump 7 and the motor 4 is provided on the handrail 9. The start and stop of the pump 7 and the motor 4 can be controlled through the control board 10.
[0035] The working principle is as follows:
[0036] When in use, the vehicle frame 8 is pushed to the position to be repaired through the handrail 9. The liquefied natural gas tank 13 is opened so that the liquefied gas stove 16 can heat the asphalt raw material in the inner tank of the heating tank 1. During the heating process, the motor 4 is turned on to stir the asphalt raw material in the inner tank of the heating tank 1 to ensure that the asphalt raw material is evenly heated and avoid bottom burning. The heated asphalt raw material is pumped out by the pump 7 and is pumped out through the discharge pipe 11 and the discharge valve 12. The operator can hold the discharge valve 12 to spray the asphalt material on the crack position to be repaired, so that the asphalt road surface is effectively repaired. The liquefied natural gas tank 13 can be stably clamped in the limit sleeve 6 through the rubber limit block 17, reducing the safety hazard caused by the shaking of the liquefied natural gas tank 13.
