Description

Technical Field

[0001] This invention belongs to the field of road repair technology and relates to an asphalt road repair device and its repair method. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. One type of asphalt pavement may crack during use. The cracks are relatively thin and long, with a width of one to two centimeters. If not treated in time, the cracks will expand and affect driving safety. When repairing cracks in asphalt pavement, workers need to first heat the pavement around the crack to soften the asphalt. Then, they use a shovel to shovel away the heated asphalt and stones, add a hot adhesive, and mix the asphalt, stones, and hot adhesive evenly. Finally, they re-compact the pavement to complete the crack repair.

[0003] A search revealed that utility model CN ​​219195591 U discloses an asphalt pavement repair device, including a vehicle body and inserts. This asphalt pavement repair device, through the setting of a broom holder and positioning components, allows the operator to connect the broom to the device during use. Once the broom handle is connected to the broom holder, the operator only needs to push the vehicle body to move the broom, thus avoiding the need to hold the broom by hand. Simultaneously, the holder can also store necessary items such as a cutting machine during use, making it convenient for the operator to carry.

In the above technical solution, through the cooperation of the sliding grooves 49 and the sliders 50, the first screw 4 can not only drive the vehicle body 9 to move, but also drive the collar 35 to rotate, thus saving an additional power source.

[0071] Reference Figure 4Two torsion springs 21 are sleeved on the outer wall of the rotating shaft 19. The ends of the two torsion springs 21 that are close to each other are fixedly connected to the rotating shaft 19, and the ends of the two torsion springs 21 that are far from each other are fixedly connected to the corresponding second fixing blocks 18. In the above technical solution, when the connecting plate 16 moves downward, it drives the rotating shaft 19 to rotate through the pull rope 15, compressing the torsion springs 21. When the connecting plate 16 moves upward, the rotating shaft 19 can wind up the pull rope 15 under the force of the torsion springs 21.

[0072] A method for repairing asphalt pavement includes the following steps:

[0073] S1. First, add an appropriate amount of tack coat oil to the oil tank 10, start the first motor 5 to drive the vehicle body 9 to move, so that the nozzle 39 moves above the repair groove 2, and at the same time start the water pump 40. The water pump 40 can spray the tack coat oil in the oil tank 10 into the repair groove 2 through the nozzle 39.

[0074] S2. Then, pour the cold patching asphalt material into the backflow box 6. The material will flow into the repair groove 2 through the backflow box 6. At the same time, start the first motor 5 to rotate in the opposite direction and drive the vehicle body 9 to move in the opposite direction, so that the cloth is evenly spread in the repair groove 2.

[0075] S3. At the same time, the second motor 14 is started to drive the connecting plate 16 to move downward. While moving, the stamping rod 24 moves back and forth to press the stamping plate 17, and the material is compacted by the stamping plate 17.

[0076] S4. Finally, when the compaction plate 29 moves above the material, the rotation of the first screw 4 can drive the compaction plate 29 to move up and down to further compact the fabric.

[0077] Working principle: When in use, the counterweight 3 is placed at both ends of the repair groove 2, and multiple first screws 4 are connected. An appropriate amount of tack coat oil is added to the oil tank 10. The first motor 5 is started to drive the first screws 4 to rotate. The rotation of the first screws 4 can drive the vehicle body 9 to move through the nut ring 8. When the spray pipe 39 moves above the repair groove 2, the water pump 40 is started. The water pump 40 can spray the tack coat oil in the oil tank 10 into the repair groove 2 through the spray pipe 39. At the same time, the rotation of the first screws 4 will drive the collar 35 to rotate through the slide groove 49 and the slider 50. The rotation of the collar 35 can drive the first bevel gear 42 to rotate. Through the second bevel gear 43, the reciprocating screw 44 is driven to rotate, which can drive the third L-shaped plate 38 to move back and forth on the rectangular hole 46, so that it is sprayed evenly.

[0078] Then, the first motor 5 is started, moving the backflow box 6 above the repair groove 2. Cold patch asphalt is poured into the backflow box 6, and the material flows into the repair groove 2 through the backflow box 6. The second motor 14 is then started, driving the second screw 12 to rotate. The rotation of the second screw 12 causes the second L-shaped frame 13 to move downward, which in turn causes the stamping plate 17 to move downward, pressing the patch material downward so that it can completely fill the repair groove 2. At the same time, the first motor 5 is started to rotate in the opposite direction, causing the vehicle body 9 to move in the opposite direction. As it moves, it fills the repair groove 2. When the connecting plate 16 moves downward, it drives the rotating shaft 19 to rotate through the pull rope 15. The rotation of the rotating shaft 19 can drive the pawl 20 to rotate. When the pawl 20 contacts the punching rod 24, it will drive the punching rod 24 to move upward. When the punching rod 24 is separated from the pawl 20, the punching rod 24 moves downward under the force of the second spring 25. When the limiting plate 26 contacts the limiting ring 27, it can drive the limiting ring 27 to punch downward, compacting the filler material into the repair groove 2.

[0079] During the movement, the first screw 4 will drive the cam 32 to rotate through the slider 50 and the collar 35. The rotation of the cam 32 can drive the top plate 30 to move up and down repeatedly through the third fixed block 33, and drive the compaction plate 29 to move through the second guide rod 28, further compacting the filling material into the repair groove 2.

[0080] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 5, the second motor 14, and the water pump 40 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
