[0003] However, such a structure is relatively heavy and will damage the flatness of the road surface when rolling back and forth. Moreover, it is time-consuming and laborious to operate through the above patent structure after laying the moisture-preserving cloth. The labor intensity is high. And even for a one-way lane, there are several meters in width, and it is very time-consuming and laborious to operate with the above structure. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is: in order to overcome the problems existing above, a concrete pavement maintenance device is provided, which solves the above problems.
[0005] The utility model solves its technical problem by adopting the following technical solutions:
[0006] The concrete pavement maintenance device includes two vertical frames and a water tank fixed between the vertical frames. There is a water filling port for adding water at the upper end of the water tank, and several drip irrigation heads are provided at the lower end of the water tank for wetting the maintenance moisture-preserving cloth. The maintenance moisture-preserving cloth is wound on a rotating shaft, and the rotating shaft is rotatably arranged between the vertical frames. After the maintenance moisture-preserving cloth is unrolled, it passes under the drip irrigation heads and is humidified by water and then laid flat on the road surface. Moving wheels are rotatably arranged on the vertical frames for moving on the roadbeds on both sides of the road surface.
[0007] Preferably, in order to improve the unrolling efficiency of the maintenance moisture-preserving cloth, a synchronous pulley is provided on the rotating shaft of one of the moving wheels, a synchronous pulley is provided on the rotating shaft of the maintenance moisture-preserving cloth, and the two synchronous pulleys are connected by a synchronous belt. After the moving wheel rotates, it drives the maintenance moisture-preserving cloth to rotate to realize its active unrolling.
[0008] Preferably, a middle beam is fixedly provided between the vertical frames by welding or bolts.
[0009] Preferably, in order to improve the flatness of the maintenance and moisture - retaining cloth after it is laid on the ground, pressing arms are hinged on both sides of the vertical frame, and a pressing roller for rolling on the maintenance and moisture - retaining cloth is rotatably arranged between the pressing arms to eliminate air bubbles and improve the fitting rate with the road surface.
[0010] Preferably, in order to reduce the damage to the flatness of the road surface, a sponge roller is fixedly sleeved outside the pressing roller. The thickness and hardness of the sponge roller can be selected and adjusted as needed. Through the sponge roller, the maintenance and moisture - retaining cloth can be effectively flattened, and the impact on the flatness of the road surface is smaller than that of the prior art.
[0011] Preferably, a horizontally - arranged cart handle is fixedly arranged on the vertical frame, which is used to facilitate the staff to push the device forward along the road to be maintained.
[0012] The advantages and positive effects of the present utility model are:
[0013] It can achieve long - continuous laying, which is simple and convenient, and effectively reduces the labor intensity.
[0014] It can achieve continuous laying after humidification. Since the wet maintenance and moisture - retaining cloth laid on the road surface in front has a certain dragging force, it will continuously pull out the maintenance and moisture - retaining cloth for laying during the forward movement of the vertical frame, which is very convenient.
[0015] The flexible sponge roller is used to level the laid maintenance and moisture - retaining cloth, and then flatten the rarely - occurring air bubbles, effectively ensuring the flatness and not causing damage to the road surface. Brief Description of the Drawings
