[0025] The present invention will be further described below with reference to the accompanying drawings: As Figure 1 — Figure 7As shown in the figure, this embodiment provides a municipal road bridge pavement maintenance device, which includes a maintenance vehicle body 1, a heating system 2, a stirring system 3, a diversion system 4, an air compressor 5, and a cleaning system 6. The heating system 2, the stirring system 3, the diversion system 4, the air compressor 5, and the cleaning system 6 are all installed on the maintenance vehicle body 1 and thus are transported along with the maintenance vehicle body 1. An asphalt tank 11 is provided on the maintenance vehicle body 1 for storing asphalt. The stirring system 3 extends into the asphalt tank 11 for stirring to maintain the temperature of the asphalt in the asphalt tank 11 uniform. The diversion system 4 is communicatively connected to the asphalt tank 11 in an openable and closable manner. Asphalt is diverted from the diversion system 4 to the crack position for pouring. The heating system 2 heats the asphalt tank 11 to maintain the temperature in the asphalt tank 11.

[0026] The cleaning system 6 includes a cleaning frame 61, a plurality of telescopic blowing devices 62, and a plurality of flexible clamping devices 63. A plurality of sliding grooves 611 are provided at the bottom of the cleaning frame 61. Each telescopic blowing device 62 is clamped on the corresponding sliding groove 611 through the corresponding flexible clamping device 63, so that the telescopic blowing device 62 slides horizontally along the corresponding sliding groove 611. When the maintenance vehicle body 1 moves forward, the telescopic blowing device 62 slides horizontally along the corresponding sliding groove 611 following the crack trend, adaptively cleaning each crack. The flexible clamping device 63 includes a clamping top plate 631, a clamping bottom plate 632, and a clamping sliding plate 633. Both the clamping top plate 631 and the clamping bottom plate 632 are installed outside the telescopic blowing device 62. The clamping sliding plate 633 slides outside the telescopic blowing device 62. Permanent magnets are provided at the positions where the clamping top plate 631 and the clamping sliding plate 633 are close to each other. The permanent magnets on the clamping top plate 631 and the clamping sliding plate 633 repel each other, so that the clamping bottom plate 632 and the clamping sliding plate 633 are clamped on the corresponding sliding groove 611, and the telescopic blowing device 62 slides horizontally along the corresponding sliding groove 611. The air compressor 5 is communicatively connected to the telescopic blowing device 62 to supply air. When the maintenance vehicle body 1 moves forward, each telescopic blowing device 62 can move horizontally according to the crack trend, and can conveniently clean each crack.

[0027] Specifically, a pushing handrail 12 is provided on the maintenance vehicle body 1, and the pushing handrail 12 is used to control the direction of the maintenance vehicle body 1. A plurality of moving wheels 13 are provided at the bottom of the maintenance vehicle body 1, and each moving wheel 13 is drivingly connected to a driving motor, and the motor is installed on the maintenance vehicle body 1.

[0028] Specifically, the heating system 2 is a natural gas heating gun, and the natural gas heating gun points to the outside of the asphalt tank 11, so as to heat the asphalt tank 11 and maintain the temperature of the asphalt in the asphalt tank 11.

[0029] Specifically, the stirring system 3 includes a heating control rod 31, a heating connecting rod 32 and a stirring frame 33. The stirring frame 33 is rotatably installed in the asphalt tank 11. The heating control rod 31 is rotatably installed on the maintenance vehicle body 1. The heating control rod 31 and the stirring frame 33 are connected by a heating connecting rod 32. The heating control rod 31 swings and drives the stirring frame 33 to swing, so that the asphalt in the asphalt tank 11 remains flowing and the asphalt temperature is balanced.

[0030] Specifically, the guide system 4 includes a guide groove 41, a material collection frame 42, a discharge pipe 43, a discharge valve 44, a discharge connecting rod 45 and a discharge control rod 46. The material collection frame 42 is installed at the bottom of the maintenance vehicle body 1 through the material collection control rod 47. The material collection control rod 47 is used to control the material collection frame 42 to align with the pavement crack position. The discharge pipe 43 is installed on the maintenance vehicle body 1. The discharge pipe 43 is connected to the asphalt tank 11. The guide groove 41 is located on the discharge pipe 43. The guide groove 41 points to the aggregate frame 42. Please note that in order to prevent the asphalt flowing out of the guide groove 41 from leaking from the aggregate frame 42, the aggregate control rod 47 drives the aggregate frame 42 to move to the bottom of the maintenance vehicle body 1. The adjustment range of the material frame 42 needs to be limited. If the aggregate frame 42 cannot cover the cracks, it is necessary to use the push handrail 12 to push the maintenance vehicle body 1 for further position adjustment. The discharge valve 44 is installed on the discharge pipe 43, and the discharge control rod 46 is rotatably installed on the maintenance vehicle body 1. The discharge control rod 46 controls the opening and closing of the discharge valve 44 through the discharge connecting rod 45. The rotation of the discharge control rod 46 drives the discharge valve 44 to open or close, so that the asphalt flows into the aggregate frame 42 through the guide groove 41. The aggregate frame 42 concentrates the asphalt, and the asphalt raises the liquid level in the aggregate frame 42, which is convenient for pouring asphalt in the cracks.

[0031] Specifically, the cleaning frame 61 has a cleaning top plate and a cleaning sliding plate 612, each sliding groove 611 is opened on the cleaning sliding plate 612, the distance between the cleaning top plate and the cleaning sliding plate 612 is greater than five centimeters, and each telescopic blowing device 62 is connected to the air compressor 5 through a hose, and the hose is located between the cleaning top plate and the cleaning sliding plate 612. The distance between the cleaning top plate and the cleaning sliding plate 612 provides space for the arrangement of the hose, and the existence of the hose provides space and travel for the lateral movement of the telescopic blowing device 62.

[0032] The basic principle of each telescopic blowing device 62 is that, under the guidance of the sliding groove 611, it can adapt to the direction of the crack and move laterally, and when it moves to the end of the crack, it can automatically retract.

[0033] Specifically, the telescopic air blowing device 62 includes an air blowing reference tube 621, an air blowing telescopic tube 622, and an air blowing return spring 623. A leakage hole 6211 is provided at a position of the air blowing reference tube 621 close to the clamping sliding plate 633. The clamping sliding plate 633 slides along the outside of the air blowing reference tube 621 to open or close the leakage hole 6211. The air blowing telescopic tube 622 slides inside the air blowing reference tube 621. Both ends of the air blowing return spring 623 are respectively pressed between the air blowing reference tube 621 and the air blowing telescopic tube 622. The acting direction of the air blowing return spring 623 causes the air blowing telescopic tube 622 to retract into the air blowing reference tube 621. After the crack ends, since the maintenance vehicle body 1 still continues to move forward, the air blowing telescopic tube 622 has to overcome the repulsive force between the clamping top plate 631 and the clamping sliding plate 633, and thus deflects, causing the leakage hole 6211 to leak air, reducing the air pressure inside the air blowing reference tube 621. The air blowing return spring 623 drives the air blowing telescopic tube 622 to retract into the air blowing reference tube 621. After the air blowing telescopic tube 622 retracts, since the air blowing telescopic tube 622 is disengaged from the lateral blockage of the crack, the air blowing telescopic tube 622 will quickly return to the correct position under the pressure of the clamping sliding plate 633. After the air blowing telescopic tube 622 returns to the correct position, the clamping sliding plate 633 blocks the leakage hole 6211 again, causing the air blowing telescopic tube 622 to extend again. When there is no crack on the road surface, the air blowing telescopic tube 622 will slide on the ground until the air blowing telescopic tube 622 encounters the next crack and deflects again at the end of the crack, and so on.

[0034] Specifically, an elastic centering spring 625 is installed on the telescopic air blowing device 62. The other end of the elastic centering spring 625 is installed on the cleaning frame 61. In order to increase the traction effect of the elastic centering spring 625, the end of the elastic centering spring 625 far from the cleaning frame 61 is installed on the clamping bottom plate 632. The pre-tightening force of the elastic centering spring 625 pulls the telescopic air blowing device 62, and the elastic centering spring 625 maintains the lateral position of the elastic centering spring 625.

[0035] A method for maintaining the road surface of a municipal road bridge, using a municipal road bridge road surface maintenance device, includes the following steps: S1: Push the maintenance vehicle body 1 to move forward above the crack so that the cleaning system 6 is located above the crack, and start the air compressor 5; S2: The telescopic air blowing device 62 extends into the crack to blow air; S3: The telescopic air blowing device 62 deflects to avoid the crack after being blocked.
