[0037] The present invention will be further described below in conjunction with the accompanying drawings:

[0038] like Figure 1 — Figure 7As shown, this embodiment provides a municipal road bridge pavement maintenance device, including 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 then transported 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 connected to the asphalt tank 11 in an openable and closable manner. The 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.

[0039] The cleaning system 6 includes a cleaning frame 61, a plurality of telescopic blowing devices 62 and a plurality of flexible clamping devices 63. The bottom of the cleaning frame 61 is provided with a plurality of sliding grooves 611. Each telescopic blowing device 62 is clamped on the corresponding sliding groove 611 by 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 direction of the crack, and adaptively cleans each crack. The flexible clamping device 63 includes a clamping top plate 631, a clamping bottom plate 632 and a clamping sliding plate 633. The clamping top plate 631 and the clamping bottom plate 632 are both mounted on the telescopic Outside the telescopic blowing device 62, the clamping sliding plate 633 slides outside the telescopic blowing device 62, and permanent magnets are provided at positions close to each other of the clamping top plate 631 and the clamping sliding plate 633. 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 connected to the telescopic blowing device 62 to realize air supply. When the maintenance vehicle body 1 moves forward, each telescopic blowing device 62 can move laterally according to the direction of the crack, so that each crack can be cleaned conveniently.

[0040] Specifically, a push armrest 12 is provided on the maintenance vehicle body 1, and the push armrest 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 connected to a driving motor, which is installed on the maintenance vehicle body 1.

[0041] Specifically, the heating system 2 is a natural gas heating gun, which is directed toward the outside of the asphalt tank 11 , thereby heating the asphalt tank 11 and maintaining the temperature of the asphalt in the asphalt tank 11 .

[0042] 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, and 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 swing of the heating control rod 31 drives the stirring frame 33 to swing, so that the asphalt in the asphalt tank 11 remains flowing and the asphalt temperature is balanced.

[0043] Specifically, the diversion system 4 includes a diversion trough 41, a collection frame 42, a discharge pipe 43, a discharge valve 44, a discharge connecting rod 45 and a discharge control rod 46. The collection frame 42 is installed at the bottom of the maintenance vehicle body 1 through the collection control rod 47. The collection control rod 47 is used to control the collection frame 42 to align with the position of the pavement crack. The discharge pipe 43 is installed on the maintenance vehicle body 1. The discharge pipe 43 is connected to the asphalt tank 11. The diversion trough 41 is located on the discharge pipe 43. The diversion trough 41 points to the collection frame 42. Please note that in order to prevent the asphalt flowing out of the diversion trough 41 from leaking from the collection frame 42, the collection control rod 47 drives the collection frame 42 to move forward. The adjustment range of the material frame 42 needs to be limited. If the aggregate frame 42 cannot cover the crack, it is necessary to use the push armrest 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 discharge control rod 46 rotates and 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.

[0044] 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, and the distance between the cleaning top plate and the cleaning sliding plate 612 is greater than five centimeters. 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 stroke for the lateral movement of the telescopic blowing device 62.

[0045] 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.

[0046] Specifically, the telescopic blowing device 62 includes a blowing reference tube 621, a blowing telescopic tube 622 and a blowing return spring 623. The blowing reference tube 621 is provided with a leakage hole 6211 near the clamping sliding plate 633. The clamping sliding plate 633 slides along the outside of the blowing reference tube 621 to open or close the leakage hole 6211. The blowing telescopic tube 622 slides in the blowing reference tube 621. The two ends of the blowing return spring 623 are respectively pressed between the blowing reference tube 621 and the blowing telescopic tube 622. The action direction of the blowing return spring 623 makes the blowing telescopic tube 622 retract into the blowing reference tube 621. After the crack is closed, since the maintenance vehicle body 1 continues to move, the blowing telescopic tube 622 has to overcome the clamping top plate 631 and the clamping sliding plate The repulsive force between 633 causes deflection, resulting in air leakage in the leakage hole 6211, and the air pressure in the blowing reference tube 621 is reduced. The blowing return spring 623 drives the blowing telescopic tube 622 to retract into the blowing reference tube 621. After the blowing telescopic tube 622 retracts, since the blowing telescopic tube 622 is free from the lateral obstruction of the crack, the blowing telescopic tube 622 will quickly return to the center under the pressure of the clamping sliding plate 633. After the blowing telescopic tube 622 returns to the center, the clamping sliding plate 633 blocks the air leakage hole 6211 again, so that the blowing telescopic tube 622 extends again. When there is no crack in the road surface, the blowing telescopic tube 622 will slide on the ground until the blowing telescopic tube 622 encounters the next crack and deflects again at the end of the crack, and so on.

[0047] Specifically, an elastic centering spring 625 is installed on the telescopic blowing device 62, and 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, one end of the elastic centering spring 625 away from the cleaning frame 61 is installed on the clamping base plate 632. The pre-tightening force of the elastic centering spring 625 pulls the telescopic blowing device 62, and the elastic centering spring 625 maintains the lateral position of the elastic centering spring 625.

[0048] A municipal road bridge pavement maintenance method, using a municipal road bridge pavement maintenance device, comprises the following steps:

[0049] S1: Push the maintenance vehicle 1 so that the cleaning system 6 is positioned above the crack and start the air compressor 5;

[0050] S2: The telescopic blowing device 62 extends into the crack to blow air;
