Description

Technical Field

[0001] The invention relates to the technical field of crack filling devices, and in particular to a crack filling device for repairing cracks in asphalt pavement. Background Art

[0002] Road construction refers to the construction of road facilities. During the public construction of roads, cracks are likely to appear on the roads due to long-term exposure to the sun and the rolling of various vehicles. If cracks on the roads are not maintained or repaired in time, the cracks will expand larger or the entire road will be damaged. In order to avoid such road damage, it is necessary to repair the cracks on the roads through grouting devices.

[0003] In the patent with publication number CN113585030B, a caulking device for repairing cracks in asphalt pavement is proposed. The caulking device for repairing cracks in asphalt pavement adopts a contact positioning device. When the caulking device is pushed to the crack, the discharge device can be started. Two guide wheels are arranged for the crack, respectively close to the two sides of the crack. The caulking device can be automatically adjusted according to the width or curvature of the crack to always align with the center of the crack. The flow rate of the caulking device can be adjusted according to the width and position of the crack to change the discharge amount, so that the discharge of the caulking device is reasonable and will not cause waste.

[0004] In the above patent, when using slurry to fill cracks for repairing, the slurry is directly poured into the cracks. Since the slurry has a certain fluidity, after pouring the slurry directly into the cracks, the slurry will flow freely in the cracks, making it difficult to level the slurry, resulting in different repair heights at different locations of the cracks, affecting the repair effect of the cracks.

One end of the bidirectional screw rod 13 penetrates the outer surface of the rectangular sleeve 6 and is fixedly installed with a second rocker wheel 14.

[0034] When in use, the second rocker wheel 14 drives the bidirectional screw rod 13 to rotate, so that the bidirectional screw rod 13 can drive the two second baffles 9 to move through the slider 8, so that the two second baffles 9 can be expanded or contracted to block the injected slurry in cracks of different widths.

[0040] When in use, the middle bracket 21 will drive the rack 29 installed on its outer surface to move when it vibrates up and down, so that the rack 29 drives the other two brackets 21 on the two sides to vibrate up and down through the gear 28 meshing with it, so that the three brackets 21 can drive the pressing plate 22 to continuously beat and vibrate the slurry poured into the crack, which can effectively remove bubbles in the slurry and make the slurry fill more tightly, thereby ensuring the quality of the later repair of the cracks. At the same time, the filled slurry can be smoothed to be flush with the road surface to ensure the flatness of the road surface.

[0042] When in use, the roller 2 drives the active bevel gear 35 to rotate, so that the active bevel gear 35 drives the driven bevel gear 34 meshing with it to rotate, and the driven bevel gear 34 drives the dial wheel 33 to rotate through the transmission shaft 32, so that the raised portion of the dial wheel 33 can dial the metal spring 30, so that the vibration generated by the metal spring 30 can be transmitted to the storage tank 3, so that the slurry adhering to the inner wall of the storage tank 3 can be shaken off, so that the slurry can be used more completely and waste can be avoided.

[0043] In this embodiment, a C-shaped plate 16 is fixedly installed on the upper surface of the vehicle plate 1, and an electric telescopic rod 17 is fixedly installed on the upper surface of the C-shaped plate 16. The telescopic end of the electric telescopic rod 17 is fixedly installed on the upper surface of the support plate 18, and an opening is opened through the upper surface of the vehicle plate 1 near the support plate 18.

[0044] When in use, the electric telescopic rod 17 drives the support plate 18 to move up and down as a whole, and the height of the pressing plate 22 can be adjusted, so that the pressing plate 22 can contact the slurry poured into the crack and vibrate and smooth the slurry.

[0045] In this embodiment, the following steps are included:

[0046] S1: Open a construction trench on the cracked road surface and clean the cracks and the construction trench;

[0047] S2: Move the device to one end of the cleaned road crack, and drive the rectangular frame 6 to move downward as a whole through the lifting screw 11, so that the first baffle 10 and the second baffle 9 installed below the rectangular frame 6 can be inserted into the crack, so that the first baffle 10 and the second baffle 9 can separate the inside of the crack;

[0048] S3: Pour the slurry in the storage tank 3 into the crack and between the first baffle 10 and the second baffle 9 through the discharge pipe 4, so that the slurry can fill the space enclosed by the first baffle 10 and the second baffle 9, thereby preventing the slurry from flowing freely in the crack, causing different repair heights at different locations of the crack and affecting the repair effect of the crack.

[0049] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the device is moved to one end of the cleaned road crack, and the lifting screw 11 is driven to rotate by the first rocker 12, so that the lifting screw 11 drives the rectangular sleeve 6 to move downward as a whole, so that the first baffle 10 and the second baffle 9 installed below the rectangular sleeve 6 can be inserted into the crack, so that the first baffle 10 and the second baffle 9 can separate the inside of the crack for segmented grouting treatment; then the discharge pipe 4 is aligned with the crack, and the valve at the discharge pipe 4 is opened, so that the slurry in the storage tank 3 can be poured into the crack and between the first baffle 10 and the second baffle 9 through the discharge pipe 4, so that the slurry can fill the space surrounded by the first baffle 10 and the second baffle 9, so as to avoid the slurry from flowing randomly in the crack, resulting in different repair heights of the cracks, affecting the repair effect of the cracks;

[0050] When the cracks are being filled, the driving motor 26 will drive the support shaft 24 to rotate, so that the multiple eccentric wheels 25 fixedly installed on the outer surface of the support shaft 24 can rotate accordingly, so that the eccentric wheel 25 can drive the middle bracket 21 to vibrate up and down when rotating, so that the pressing plate 22 installed at the bottom end of the bracket 21 can vibrate and smooth the slurry poured into the cracks, which can effectively remove bubbles in the slurry, make the slurry fill more tightly, ensure the quality of the later repair of the cracks, and at the same time, can smooth the filled slurry to be flush with the road surface to ensure the flatness of the road surface;

[0051] When the pushing device as a whole moves slowly along the crack to fill the crack, the roller 2 will drive the active bevel gear 35 to rotate, so that the active bevel gear 35 drives the driven bevel gear 34 meshing with it to rotate, and the driven bevel gear 34 drives the dial wheel 33 to rotate through the transmission shaft 32, so that the raised part of the dial wheel 33 can dial the metal spring 30, so that the vibration generated by the metal spring 30 can be transmitted to the storage tank 3, so that the slurry adhering to the inner wall of the storage tank 3 can be shaken off, so that the slurry can be used more completely and waste can be avoided.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
