Technical Field
[0001] The present invention relates to the technical field of crack repair, and in particular to a crack repair device for highway engineering. Background Art
[0002] Highway cracks are one of the common highway diseases. Timely repair is crucial to maintaining the performance of the highway and extending its service life. Cracks are mainly caused by the tensile stress generated by the pavement structure under the influence of factors such as driving load and temperature changes, which exceeds the tensile strength of the pavement material, or due to uneven settlement of the roadbed, insufficient strength of the pavement base, construction quality problems or aging and fatigue damage of the pavement material. The current mainstream crack repair method mostly uses grouting. First, clean up the debris and dust in the cracks, and then use grouting equipment to pour sealant or emulsified asphalt and other materials into the cracks to ensure that the materials are fully filled, and finally perform surface finishing.
[0003] At present, when repairing cracks in highways, due to the certain temperature of emulsified asphalt, it takes a certain amount of time to dry after the repair is completed. Natural drying takes a long time, and after drying, due to the flow and expansion and contraction of the filler, the surface needs to be trimmed. During this process, traffic control is still required, which puts a lot of pressure on traffic. Therefore, we propose a crack repair device for highway engineering, which can cool and trim the filler in time after the repair, reducing the time for crack repair and reducing traffic pressure.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0019] like Figures 1 to 6 As shown, this embodiment proposes a crack repair device for highway engineering, including an asphalt repair machine body, which includes a vehicle body 101 and a caulking head 102. The asphalt repair machine also includes components such as an asphalt tank, a mixing tank, and an asphalt pump. The asphalt is heated and mixed by the mixing tank, and the asphalt is transported to the caulking head 102 by the asphalt pump. As the vehicle body 101 moves, the asphalt is filled into the cracks of the highway to fill the cracks. This is a prior art known to those skilled in the art and is not the innovation of this embodiment. This embodiment is based on the existing asphalt repair machine. The asphalt repair machine body is improved on the basis of the present invention, and the asphalt repair machine body is not described in detail here. It also includes a shaping mechanism and a finishing mechanism. Compared with the crack repairing device in the prior art, the present invention sets an air-cooling component to cool the repaired caulking, and then flattens and shapes the asphalt through the flattening roller 403, and at the same time transports cold water to the flattening roller 403 and the fan blade 202, so as to further improve the cooling and shaping effect of the asphalt. After the asphalt is shaped, the caulking is polished by the grinding disc 502, which reduces the subsequent drying and polishing time, reduces the time for crack repair, and improves work efficiency.
[0020] The shaping mechanism is arranged at the rear of the caulking head 102, and the shaping mechanism is used to shape the asphalt after repair. The shaping mechanism includes an air-cooling component and a flattening component. The air-cooling component is used to cool the asphalt after caulking. The air-cooling component includes an air-cooling shaft 201 and a fan blade 202. The air-cooling shaft 201 is rotatably arranged on the vehicle body 101, and the fan blade 202 is fixedly connected to the bottom end of the air-cooling shaft 201. In order to realize the rotation of the fan blade 202, a driving component is also included. The driving component is used to drive the air-cooling shaft 201 to rotate. The driving component includes a driving gear 30 1 and the driven gear 302, the driving gear 301 is rotatably connected to the vehicle body 101, the vehicle body 101 is equipped with a motor 303, the driving gear 301 is fixedly connected to the output end of the motor 303, the driven gear 302 is fixedly sleeved on the outside of the air-cooling shaft 201, the driven gear 302 and the driving gear 301 are engaged, the motor 303 can drive the driving gear 301 to rotate, thereby driving the driven gear 302 and the air-cooling shaft 201 to rotate, so that the fan blades 202 rotate to form cold wind, which promptly cools the asphalt after filling.
[0021] The flattening component is used to flatten the asphalt after filling. The flattening component includes a fixed frame 401, a flattening frame 402 and a flattening roller 403. The fixed frame 401 is fixedly connected to the vehicle body 101. The flattening frame 402 is connected to the bottom of the fixed frame 401 through a compression spring and a telescopic rod. The flattening roller 403 is rotatably connected to the flattening frame 402. The flattening roller 403 is in contact with the road surface. Under the action of the compression spring, the flattening roller 403 is pressed against the road surface. The flattening roller 403 has a large weight. In the process of moving with the vehicle body 101, the flattening roller 403 and the grouting head 102 have the same moving trajectory. The flattening roller 403 flattens the asphalt after filling and accelerates the shaping of the asphalt.
[0022] The finishing mechanism is arranged at the rear of the shaping mechanism, and the finishing mechanism is used to trim the caulking after shaping. The finishing mechanism includes a grinding shaft 501 and a grinding disc 502. The grinding shaft 501 is rotatably arranged on the vehicle body 101, and the grinding shaft 501 is lifted and lowered along with the flattening frame 402. The grinding disc 502 is fixedly connected to the bottom end of the grinding shaft 501, and the grinding disc 502 is in contact with the road surface. In order to realize the lifting and lowering of the grinding shaft 501 along with the flattening frame 402, the flattening frame 402 is fixedly connected with a follower frame 503, and the grinding shaft 501 is rotatably connected to the follower frame 503. In order to reduce the splashing of asphalt debris during grinding, the vehicle A protective cover 504 is fixedly connected to the body 101. A through hole is opened on the protective cover 504 for the grinding shaft 501 to pass through. The grinding disc 502 is located inside the protective cover 504. A plurality of baffles 505 are fixedly connected to the bottom end of the protective cover 504. Under the action of the compression spring, the flattening roller 403 is pressed against the road surface. At the same time, under the action of the follower frame 503, the grinding roller drives the grinding disc 502 to press against the road surface. The grinding disc 502 is driven to rotate by the grinding shaft 501 to grind the shaped asphalt caulking smooth, reduce the bumps on the road surface, and ensure the beauty of the highway and the normal driving of vehicles.
[0023] In order to improve the cooling effect of filling, a cooling component is also included, which includes a cold water tank 601, a water pump 602 and a cold water pipe network 603. The cold water tank 601 is fixedly connected to the vehicle body 101, and the water pump 602 is installed on the vehicle body 101. The water suction port of the water pump 602 is connected to the cold water tank 601, and an air cooling tank 604 is fixedly connected to the vehicle body 101. The fan blades 202 are located inside the air cooling tank 604, and the cold water pipe network 603 is located inside the air cooling tank 604. The cold water pipe network 603 is connected to the water outlet of the water pump 602, and the cold water pipe network 603 is connected to the top of the cold water tank 601 through a return pipe. The cold water in the cold water tank 601 is sent to the inside of the cold water pipe network 603 through the water pump 602 to reduce the temperature inside the air cooling tank 604. When the fan blades 202 rotate, the low-temperature air in the air cooling tank 604 is blown to the ground, thereby accelerating the cooling efficiency of the asphalt.
[0024] In order to further improve the cooling effect of the caulking, the flattening roller 403 is connected to the flattening frame 402 through the rotating shaft 404. The rotating shaft 404 is connected to the water inlet pipe 405 and the water outlet pipe 406. The interior of the flattening roller 403 is provided with a cold water cavity 407. The water inlet pipe 405 is connected to the water outlet of the water pump 602. The water outlet pipe 406 is connected to the cold water network 603. The water pump 602 first delivers cold water to the interior of the flattening roller 403 to reduce the temperature of the flattening roller 403. When the flattening roller 403 moves with the vehicle body 1 01 While walking to flatten and shape the caulking, it also helps to cool the caulking. At the same time, the surface temperature of the flattening roller 403 is low, which reduces the adhesion of asphalt to the surface of the flattening roller 403. The cold water eventually flows back to the cold water tank 601 through the cold water pipe network 603, realizing the recycling of cold water. At the same time, the cold water exchanges heat with the outside during transportation to ensure the low temperature of the cold water. The outside of the cold water tank 601 is fixedly connected with multiple heat sinks, which can help the cold water in the cold water tank 601 to be in a low temperature state, ensuring the cooling effect on the asphalt.
[0025] In order to realize the rotation of the grinding disc 502, the grinding disc 502 is connected to the air-cooled shaft 201 through a transmission assembly. The transmission assembly includes a sprocket 1 701 and a sprocket 2 702. The sprocket 1 701 is rotatably connected to the vehicle body 101. The vehicle body 101 is fixedly connected to a support frame 703. The sprocket 1 701 is rotatably connected to the support frame 703 through a rotating tube. The sprocket 1 701 and the grinding shaft 501 are slidably connected. The sprocket 2 702 is fixedly connected to the end of the air-cooled shaft 201. The sprocket 1 701 and the sprocket 2 702 are connected through a chain 704. The grinding shaft 50 1 is fixedly connected to the outside with a slider, and a slide groove matching the slider is opened on the sprocket 1 701. The grinding shaft 501 passes through the rotating tube, and the motor 303 drives the air-cooling shaft 201 to rotate, so that the fan blades 202 are cooled by air. At the same time, the air-cooling shaft 201 drives the sprocket 1 701 to rotate, and the sprocket 2 702 and the grinding shaft 501 are rotated under the transmission action of the chain 704, driving the grinding disc 502 to grind and trim the asphalt after shaping. At the same time, through the sliding cooperation between the grinding shaft 501 and the sprocket 2 702, the follower frame 503 drives the grinding shaft 501 to rise and fall.
[0026] The working principle or use process of the crack repair device for highway engineering is as follows: The vehicle body 101 is moved to the position of the road that needs to be repaired, and the caulking head 102 is aligned with the road crack. The staff pushes the vehicle body 101 to move, and the asphalt repair machine body transports asphalt to the caulking head 102 to fill the road crack. As the vehicle body 101 moves along the crack, the fan blade 202 moves to the top of the filled asphalt, and the motor 303 drives the driving gear 301 to rotate, thereby driving the driven gear 302 and the air-cooling shaft 201 to rotate, so that the fan blade 202 rotates to generate cold air to cool the caulking. Then the flattening roller 403 moves to the asphalt position after air cooling to flatten and shape the asphalt. At the same time, the water pump 602 transports the cold water in the cold water tank 601 to the flattening roller 403 and the inside of the cold water pipe network 603, thereby improving the cooling effect of the flattening roller 403 and the fan blades 202 on the asphalt. Finally, the grinding disc 502 moves to the filling position after cooling and shaping. Through the transmission action of sprocket 1 701, sprocket 2 702 and chain 704, the grinding shaft 501 drives the grinding disc 502 to rotate, and the filling can be polished.
