In order to ensure the repair effect, the cracks need to be simply cleaned during the spraying, and the sprayed cracks need to be flattened. The process is relatively cumbersome, and usually personnel hold the gun head to perform spray repair, which is laborious after long-term use. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a road crack repair device comprises a bottom box 1, a constant temperature material storage box 2 is fixedly installed on the top of the bottom box 1, a feed pump 3 is installed on the top of the bottom box 1, and the discharge port of the feed pump 3 is connected to a discharge rod 5 through a feed pipe 4, and a flattening component 7 is arranged at the rear position of the outer ring of the discharge rod 5;

[0024] The flattening assembly 7 includes a mounting plate 8, a nozzle 6 is provided at the bottom end of the discharge rod 5, the mounting plate 8 is fixedly installed at the lower position of the outer ring of the discharge rod 5, a pressure rod 9 is slidably installed at the rear position of the upper and lower ends of the mounting plate 8, a pressure roller 10 is movably installed at the bottom end of the pressure rod 9 through a mounting frame, the rear end of the pressure roller 10 is fixedly connected to a support plate, a scraper 14 is slidably installed through the upper and lower ends of the support plate, and the bottom end of the scraper 14 is in contact with the outer ring of the pressure roller 10.

[0025] In this embodiment, a mounting rod 13 is slidably installed on both sides of the upper and lower ends of the scraper 14, and the bottom end of the mounting rod 13 is fixedly connected to the support plate. A clamping nut is threadedly connected to the upper position of the outer ring of the mounting rod 13, and a clamping spring is arranged around the outer ring of the mounting rod 13, and the two ends of the clamping spring are respectively against the support plate and the scraper 14. Through the provided clamping spring, the scraper 14 can be continuously pushed to fit the outer ring of the pressure roller 10, so that after the scraper 14 is slightly rubbed, it can still scrape the asphalt liquid.

[0026] In this embodiment, the upper position of the outer ring of the pressure rod 9 is threadedly connected to the limiting block 11, and a pressure spring 12 is arranged around the outer ring of the pressure rod 9, and the upper and lower ends of the pressure spring 12 are respectively abutted against the upper and lower opposite surfaces of the pressure roller 10 and the mounting plate 8. The extending length of the pressure rod 9 can be limited by the set limiting block 11, and the set pressure spring 12 can facilitate the pushing of the pressure roller 10 downward for compaction, facilitate the rolling and flattening of the sprayed asphalt, and improve the repair flatness.

[0027] In this embodiment, the outer ring of the discharge rod 5 is fixedly installed with connecting plates on both sides, and an electric telescopic rod 15 is installed at the top of the connecting plate and on the side away from the discharge rod 5. The end of the push rod of the electric telescopic rod 15 passes through the connecting plate and is installed with a universal caster 16. By setting the universal caster 16 to contact the ground, it is convenient to support the discharge rod 5. Therefore, when spraying liquid repair, personnel do not need to hold the discharge rod 5 for a long time to repair, which is convenient to reduce labor intensity. In addition, by telescoping the push rod of the electric telescopic rod 15, it is convenient to adjust the height between the discharge rod 5 and the ground, thereby adjusting the height of the repair liquid discharge, and the flexibility of use is high.

[0028] In the present embodiment, a fixing plate is movably installed at the upper position of the outer ring of the discharging rod 5 through a damping shaft, and a ventilation rod 17 is threadedly connected to the upper and lower ends of the fixing plate, and the bottom end of the ventilation rod 17 is provided with an air outlet head matching the discharging rod 5, and the top of the ventilation rod 17 is connected with an exhaust pipe 18 and an air supply pipe 19 through a three-way joint, and a valve is provided at the connection between the exhaust pipe 18, the air supply pipe 19 and the three-way joint. Since the ventilation rod 17 is threadedly connected to the fixing plate, it is convenient to screw the ventilation rod 17 to adjust the height of the air outlet head, and at the same time, by unscrewing the valves at different positions, the ventilation rod 17 can be adjusted to be connected with the exhaust pipe 18 and the air supply pipe 19.

[0029] In the present embodiment, an ash pump is installed at the front position of the top of the bottom box 1, and the ash suction port of the ash pump is connected to the end of the exhaust pipe 18 away from the ventilation rod 17. A collecting box is arranged inside the bottom box 1, and the ash discharge port of the ash pump is connected to the collecting box. By starting the ash pump, it is convenient to collect and clean the dust in the crack to be repaired in front of the discharge rod 5, so as to avoid the accumulation of a large amount of dust that interferes with the repair effect.

[0030] In this embodiment, a jet fan is installed at the front position of the top of the bottom box 1, and the end of the air supply pipe 19 away from the ventilation rod 17 is connected to the air outlet of the jet fan. By setting and starting the jet fan, it is convenient to spray air on the repaired road surface, thereby accelerating the cooling speed of the asphalt, allowing the asphalt road surface to cool down faster, so that it can be opened to traffic faster, reducing interference with traffic.

[0031] It should be noted that the utility model is a road crack repair device. When in use, first, the bottom box 1 can be fixed to the external conveying device as needed, and then the bottom box 1 is moved to the repaired road surface, and then the discharge rod 5 is moved to a suitable position as needed, and it is ensured that the nozzle 6 has been aligned with the crack. Since the discharge rod 5 is connected to the discharge port of the feed pump 3 through the feed pipe 4, the feed pump 3 can be started as needed to extract the asphalt liquid in the constant temperature storage box 2, and transport it to the nozzle 6 and spray it on the road crack, so as to repair it;

[0032] During the repair process, the personnel can push the discharge rod 5 to move in the direction of the crack extension. During the movement, since a ventilation rod 17 is provided in front of the discharge rod 5, and the ventilation rod 17 is connected to an air extraction pipe 18 and an air supply pipe 19 through a three-way connector, and the air extraction pipe 18 is connected to an ash extraction pump, and the air supply pipe 19 is connected to an air blower, the ash extraction pump can be opened as needed to collect and clean the dust in the crack in front of the discharge rod 5, thereby avoiding a large amount of dust accumulation that interferes with the repair effect.

[0033] At the same time, during repair, a pressure roller 10 is installed behind the discharge rod 5 through various components. The pressure roller 10 moves with the discharge rod 5 to roll and flatten the sprayed asphalt, which is convenient for improving the repair flatness. At the same time, a scraper 14 is arranged behind the pressure roller 10, and the scraper 14 is in contact with the outer ring of the pressure roller 10, so that the asphalt liquid that may adhere to the pressure roller 10 can be scraped off by the scraper 14 to avoid it from solidifying on the pressure roller 10, thereby preventing the pressure roller 10 from being uneven due to the adhesion and solidification of asphalt after long-term use, thereby avoiding affecting the rolling effect.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
