Description

Technical Field

[0001] The present invention relates to the technical field of road surface maintenance, and specifically to a road surface maintenance device for road and bridge engineering. Background Technique

[0002] Highways are the lifeblood of the national economy, the image of regional development, and the foundation of national defense stability. After the concrete road surface is poured, if the climate is hot and the air is dry, and maintenance is not carried out in time, the moisture for concrete maintenance in the concrete will evaporate too quickly, resulting in dehydration. This will cause the cement particles that have formed a gel body to not be fully hydrated and cannot be transformed into stable crystals, lacking sufficient bonding force, and thus flaky or powdery peeling will occur on the concrete surface; in addition, when the concrete does not have sufficient strength, premature evaporation of water will also cause relatively large shrinkage deformation and dry shrinkage cracks.

[0003] After the concrete road surface is laid, in order to increase the service strength of the road surface, water injection maintenance is usually carried out on the road surface after the road surface is laid. During the spraying maintenance process, it is necessary to manually drag a rubber water pipe to sprinkle water for maintenance, which is time-consuming and laborious. Moreover, when the width of the road surface is different, it is necessary to walk back and forth manually to spray water on the concrete road surface, which will cause uneven spraying, waste water resources, and the spraying height cannot be adjusted either. When it is necessary to spray water for maintenance on some concrete walls, it will be very inconvenient. Therefore, in view of the above current situation, there is an urgent need to develop a road surface maintenance device for road and bridge engineering to overcome the deficiencies in current practical applications.

[0037] In one embodiment of the present invention, please refer to Figure 9 and Figure 11 , the automatic expansion and retraction assembly 12 includes: an induction pressure guiding assembly 40, a connection cavity 41, a fixed inner pipe 42, a gas guiding cylinder 43, an annular sleeve 44, a communicating air pipe 45, a lifting control pipe 46, a control tooth block 47, an induction piston 48, and a directional rail 49. The connection cavity 41 is arranged on the installation base 1. The connection cavity 41 is connected to the fixed inner pipe 42 fixedly connected to the installation base 1. The fixed inner pipe 42 penetrates through the sleeve support pipe 31 and is connected to the gas guiding cylinder 43 rotatably connected to the outer side of the top of the diversion seat 14 at the other end. An annular sleeve 44 is arranged around the outer side of the gas guiding cylinder 43. The annular sleeve 44 is fixedly connected to the diversion seat 14, and a plurality of communicating air pipes 45 fixedly connected to the gas guiding cylinder 43 are arranged on the inner side. The barrel wall of the annular sleeve 44 is also fixedly connected to one end of the lifting control pipe 46.

[0038] In this embodiment, the push control column 36 cooperates with the movement of the regulation frame 35 to drive the induction pressure guiding assembly 40. The air inside the driving connection cavity 41 enters the inside of the air guiding cylinder 43 along the fixed inner tube 42, and then enters the inside of the annular sleeve 44 along the connecting air pipe 45, and then enters the inside of the lifting control groove through the induction lifting control tube 46, and cooperates with the induction piston 48 to realize the lifting of the control tooth block 47. The control tooth block 47 moves up and down along the orientation rail 49. The orientation rail 49 is of a T-shaped structure. The control tooth block 47 cooperates with the winding and unwinding gear 17 to drive the winding and unwinding rotating tube 16 to rotate. The winding and unwinding rotating tube 16 drives the spray main pipe 18 to rotate synchronously to complete the unfolding of the spray main pipe 18. When the push control column 36 releases the drive of the induction pressure guiding assembly 40, the induction pressure guiding assembly 40 can complete the automatic recovery of the two spray main pipes 18, so that when the unused equipment moves, it will not cause interference to both sides, improving its convenience during movement. At the same time, it can ensure that the distance-adjusting spraying and curing assembly 11 sprays the concrete road surface or concrete wall accurately and effectively. By setting the automatic unfolding and retracting assembly 12, the automatic unfolding and retracting of the distance-adjusting spraying and curing assembly 11 can be completed, which is convenient for people to store and move the equipment, and ensures the accuracy and effectiveness of the equipment during spraying and curing.

Initially, the return spring cooperates with the drive control box 50 to pull the second piston, so that the second piston abuts against the positioning ring 55. At this time, the spray main pipe 18 is vertically arranged. The push control column 36 pushes the sensing plate 53 as the control frame 35 moves. The sensing plate 53 drives the second piston to move inside the energy control tube 51, and cooperates with the transmission control tube 54 to extract the air inside the connection cavity 41. Furthermore, it cooperates with the fixed inner tube 42, the air guide cylinder 43 and the connecting air pipe 45 to extract the air inside the annular sleeve 44, and uses the lifting control tube 46 to extract the air inside the lifting control groove, so as to realize the upward movement of the control tooth block 47, thereby driving the spray main pipes 18 on both sides to unfold to both sides, and then completing the spraying and maintenance of the concrete road surface. By setting the induction pressure guiding assembly 40, it can cooperate with the steering recovery assembly 9 to realize the quantitative unfolding and recovery of the spray main pipe 18, ensuring the accuracy and effectiveness of spraying.

[0042] In this embodiment, a clamping interface is provided on the frame wall of the filter residue frame 56 for the cleaning brush 59 to pass through the filter residue frame 56 when the filter residue frame 56 is inserted. A clamping block that is fixedly connected to the inner wall of the water tank 2 and is clamped with the clamping interface is provided. When water enters the inside of the water tank 2 along the water injection pipe 3, the filter residue frame 56 filters impurities in the water, thereby avoiding blockage problems during the operation of the equipment and ensuring the stability of the equipment during operation. The forward and reverse motor 57 drives the support frame 58 to rotate alternately clockwise and counterclockwise. The support frame 58 drives the cleaning brush 59 to move synchronously through the positioning rod 60, sweeping the impurities originally accumulated directly below the water injection pipe 3 to the side away from the water injection pipe 3, ensuring the rapidity of water drainage. By setting the impurity removal and self-cleaning unit 5, the water entering the inside of the water tank 2 can be filtered, avoiding blockage of the equipment caused by impurities, ensuring the stability of the equipment during operation, and being able to clean the impurities on the filter residue frame 56 during the water inlet process, ensuring the smoothness of filtration, and thus ensuring the water injection efficiency, thereby improving the working efficiency of the equipment.
