Description

Technical Field

[0001] The present invention relates to the technical field of road surface crack repairing, and more specifically, to a highway road surface crack repairing device. Background Art

[0002] Highway pavement cracks need to be repaired with cold asphalt emulsifiers, where cold asphalt emulsifier repair liquid can be applied at room temperature, avoiding the inconvenience and safety hazards caused by high-temperature operation. At the same time, the emulsifier can reduce the surface tension of asphalt, making it easier to mix evenly with aggregates, thereby improving the stability and durability of the cold patch material, making it easier to repair highway pavement cracks.

[0003] After searching the existing public documents, the patent announcement number CN215482202U discloses a road surface crack filling device for highway roadbed maintenance. This technology pushes the bearing plate to move along the crack when repairing the crack. The repair material in the heating barrel is heated and then transported to the road surface crack through the conveying pipe. The repair material in the crack is pressed by the pressure wheel so that the repair material can fill the crack. Then, the shovel mouth of the bucket is adjusted to fit the road surface through the adjustment component, and the excess repair material is flattened. When there is a lot of repair material in the bucket, the bucket is adjusted to rotate around the guide rod, so that the repair material in the bucket slides into the waste box for recycling and secondary use. Through the cooperation of the pressure wheel and the bucket, the crack can be quickly repaired and leveled, and the labor of the staff is also reduced. However, this technology still has the following problems.

[0004] During the process of repairing cracks on the highway pavement, although the patching agent can be covered and laid in the cracks on the highway pavement, since the sizes and widths of the cracks on the highway pavement are different, and the patching agent covering position is a fixed spraying position, it is difficult to fully repair and cover when encountering larger cracks on the highway pavement. There are large repair defects and repair dead angles. It is difficult to automatically adjust to the repair position of the specified width according to the width of the highway pavement gap, and it is difficult to adjust to the specified scraping position.

When the twice value of the width distance sensor exceeds the crack width value, the adjustment motor is turned off by the controller, and the maximum opening value between the two rectangular nozzles can be automatically adjusted to both sides according to the crack width, so that it can be automatically adjusted to the repair position of the specified width according to the width of the highway pavement gap, and the covering paving repair is realized, so that the highway pavement repair has a wider adaptive adjustability, avoids the existence of repair dead angles, has a wider repair range, and has a better repair effect.

[0015] 2. The present invention utilizes a synchronous adjustment mechanism for the repair and scraping width.

When the distance value sensed by the distance sensor is the same as the value set by the controller, the electric cylinder is turned off by the controller and the crack width detection probe is turned on. In this way, the crack width detection probe performs width sensing and identification of cracks on the highway pavement, and timely knows the width value of the crack to be repaired, so that it can quickly adjust to the repair position of the specified width according to the crack width value, as well as the repair and scraping gap, so that the highway pavement repair has a wider adaptive adjustability and a better repair effect.

[0017] According to the mutual influence of the above multiple functions, first the crack width detection probe is positioned at the specified distance, the crack width detection probe performs width sensing and identification of cracks on the highway pavement, and then automatically adjusts the maximum opening value between the two rectangular nozzles until the value twice the width distance sensor senses exceeds the crack width value, and finally the scraping width of the two adjustment scrapers can also be adjusted synchronously with the crack width value. In summary, the repair position can be adjusted to the specified width according to the crack width, and can be synchronously adjusted to the specified scraping position to achieve covering and paving repair, making the highway pavement repair more adaptive and adjustable, avoiding the existence of repair dead corners, and the repair range is wider, making the highway pavement crack repair effect better.

[0037] The working principle of the highway pavement crack repairing device of the present invention is as follows:

[0038] First, when the present invention is discharging materials by moving, the internal debris of the cracks on the highway pavement is first cleaned, and then the top cover of the repair agent holding barrel 19 is opened, and the highway repair liquid is poured into the repair agent holding barrel 19, and the mobile frame 20 is pushed, and the mobile frame 20 is moved to the repair position of the highway pavement cracks, and the operator holds the hand on the holding rod 15. At the same time, the controller 16 is powered by the battery 24, and the controller 16 is started. The controller 16 starts the booster fan 23, so that the external boosted air is poured into the booster box 22, and is pressurized into the two booster pipes 21 through the booster box 22, and is pressurized into the repair agent holding barrel 19 by the two booster pipes 21, and the valve 18 is opened, so that the repair agent enters the valve 18 along the repair agent holding barrel 19. The liquid enters the repair branch pipe 1 through the valve 18, is poured into the two docking hoses 12 from the repair branch pipe 1, is poured into the two rectangular nozzles 9 through the two docking hoses 12, and is discharged downward along the rectangular spray holes 11 of the two rectangular nozzles 9 to cover the cracks on the highway pavement.

[0039] Secondly, when the present invention performs crack width positioning detection, the electric cylinder 32 is started to move downward, the electric cylinder 32 drives the push rod 33 to move downward, the push rod 33 makes the push block 34 move downward, and the push block 34 can make the distance sensor 35 move downward, the distance sensor 35 drives the concave sleeve 37 to move downward, and the concave sleeve 37 makes the crack width detection probe 36 move downward synchronously. The distance sensor 35 can sense the distance between the distance sensor 35 and the highway pavement. When the distance value sensed by the distance sensor 35 is the same as the value set by the controller 16, the electric cylinder 32 is turned off by the controller 16. The crack width detection probe 36 is turned on, and the crack width detection probe 36 performs width sensing and identification on the highway pavement crack, so that the highway pavement crack width data can be collected and the width value of the highway pavement crack repair can be known.

[0040] Then, when the present invention performs linkage adjustment of the repair width, according to the width value collected by the crack width detection probe 36, the controller 16 starts the adjustment motor 4, the adjustment motor 4 drives the adjustment screw 5 to rotate, the adjustment screw 5 drives the threaded sleeve 6 to move backward under the action of the thread transmission force, the threaded sleeve 6 drives the support frame 7 to move backward, the support frame 7 drives the sliding shaft 8 to rotate counterclockwise, and the other sliding shaft 8 rotates clockwise, and at the same time, the two sliding shafts 8 slide inside the support frame 7, and the distance between the two sliding shafts 8 increases. At the same time, the sliding shaft 8 drives the two slip rings 14 to slide in the upper limit position on the support frame 7. At the same time, the sliding shaft 8 drives the rectangular nozzle 9 to rotate counterclockwise, the rectangular nozzle 9 drives the rotating shaft 10 to rotate counterclockwise, and the rotating shaft 10 rotates counterclockwise inside the socket block 2. At the same time, the distance of the sliding shaft 8 is sensed by the width distance sensor 38, and the sensed value is twice. When the twice value sensed by the width distance sensor 38 exceeds the crack width value, the adjustment motor 4 is turned off by the controller 16, so that the maximum opening value between the two rectangular nozzles 9 can be automatically adjusted to both sides according to the crack width, and the two rectangular nozzles 9 can cover the repair liquid into the crack of the specified width.

[0041] At the same time, when the present invention performs synchronous adjustment of the repair scraping width, when the rectangular nozzle 9 rotates counterclockwise, the adjusting scraper 30 will be driven to rotate counterclockwise, and the other rectangular nozzle 9 will drive the other adjusting scraper 30 to rotate clockwise, and the adjusting scraper 30 will drive the slide bar 28 to rotate counterclockwise, and the slide bar 28 will drive the two rectangular nozzles 9 to rotate counterclockwise on the guide sleeve 26, and the slide bar 28 will rotate counterclockwise along the inside of the guide groove 27. At the same time, the sleeve block 2 supports the pillar 25, and the pillar 25 supports the guide sleeve 26. In this way, the two adjusting scrapers 30 can rotate in different directions, so that the adjusting scraper 30 squeezes the deformation spring sheet 31, and the deformation spring sheet 31 can be deformed. In this way, when the two rectangular nozzles 9 are adjusted according to the crack width value, the scraping width of the two adjusting scrapers 30 can also be synchronously adjusted following the crack width value, so that it is suitable for scraping operations with different crack widths.

[0042] Finally, when the present invention moves to repair and level the surface, when the holding rod 15 moves, it will drive the repair branch pipe 1 to move, the repair branch pipe 1 drives the support block 13 to move, the support block 13 drives the sleeve block 2 to move, and the sleeve block 2 allows the two rotating shafts 10 to move synchronously, and the two rotating shafts 10 respectively drive the two rectangular nozzles 9 to move along the cracks of the highway pavement, so that the two rotating shafts 10 can continuously change the repair liquid according to the crack width value to cover the crack. At the same time, the two rectangular nozzles 9 can synchronously drive the two adjustment scrapers 30 and the deformation spring piece 31 to move, so that the two adjustment scrapers 30 can follow the two rectangular nozzles 9 to continuously adjust the leveling width, so that it is suitable for cracks of different widths to perform the repair agent leveling operation, so that the highway pavement cracks of different widths can be automatically adjusted in width to cover and repair, even for larger gaps, they can be covered and repaired.
