Description

Technical Field

[0001] This utility model relates to the field of road repair equipment technology, and in particular to a device for repairing surface cracks in municipal roads and bridges. Background Technology

[0002] Municipal roads refer to urban roads. Based on their location in the road network, traffic function, and service functions along their route, municipal roads are classified into five levels: expressways, arterial roads, secondary arterial roads, local roads, and intra-district roads. Their construction materials are mainly asphalt and concrete. Asphalt pavements are most widely used as road surface layers due to their advantages such as low cost, low noise, comfortable driving, quick construction, and convenient maintenance. However, cracking is a common form of damage in asphalt pavements, especially in winter and spring when the added traffic load causes surface cracks. Timely repair is necessary to prevent damage to the internal road structure and driving safety.

[0003] Currently, most surface layer crack repairs are done manually, by shoveling the repair material into the crack, grinding it flat, and pressing it firmly. While this method provides good repair quality, it is labor-intensive and inefficient.

[0004] Therefore, a device for repairing surface cracks in municipal roads and bridges is proposed. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a surface crack repair device for municipal roads and bridges, including a base plate 1 for installing components of the device. A caster wheel 2 is installed at the bottom of the base plate 1 to allow the device to move. A push handle 3 is provided on one side of the base plate 1 for easy operation by workers. A controller 4 is installed at the upper end of the push handle 3, allowing operation of the electrical components in the device through the externally purchased controller 4, making operation more convenient. A large movable opening 5 is provided in the middle of the base plate 1, allowing workers to observe the filling effect from top to bottom. A storage box is installed at the upper end of the movable opening 5 via a support plate. 6. The storage box 6 stores repair materials for timely use. A rotating shaft 11 is rotatably mounted in the middle of the storage box 6, and several stirring rods 12 are mounted on the outside of the rotating shaft 11. A motor 13 is mounted at the top of the storage box 6, and the output end of the motor 13 is connected to the rotating shaft 11. The motor 13 drives the rotating shaft 11, causing the stirring rods 12 to agitate the repair materials inside the storage box 6, which can prevent the materials from clumping. A feed inlet 7 is provided at the top of the storage box 6 to facilitate the input of materials, and a funnel-shaped discharge outlet 8 is provided at the bottom of the storage box 6 to facilitate downward discharge. A solenoid valve 9 is installed inside the discharge outlet 8 to control the material feeding and discharge. At the lower end of the opening 8, a feeding pipe 15 is connected via a telescopic tube 10, passing through the movable nozzle 5. This allows the feeding pipe 15 to move freely left and right, enabling normal feeding. A curved pull rod 14 is installed on one side of the feeding pipe 15 and slidably connected to the base plate 1. This allows the position of the feeding pipe 15 to be adjusted via the pull rod 14, enabling feeding at different locations. A movable slide groove 113 is provided on one side of the base plate 1. A sliding rod 114 is fixedly connected inside the movable slide groove 113. A slider 115 is slidably installed inside the movable slide groove 113. A sliding hole 116 is provided in the middle of the slider 115 and slidably connected to the sliding rod 114. This allows the pull rod 14 to move via the slider 115 and the sliding rod 114, enabling it to move left and right on the moving slide 113 and achieve side limiting. The upper end of the slider 115 is provided with a rotating plate 117 connected to the pull rod 14, and the upper end of the slider 115 is provided with a rotating connecting block 119. The lower end of the rotating plate 117 is provided with a rotating connecting hole 118 rotatably connected to the rotating connecting block 119. This allows the pull rod 14 to be rotated under the action of the rotating connecting hole 118 and the rotating connecting block 119, so that the position of the feeding pipe 15 in the moving nozzle 5 can be adjusted, allowing it to feed materials according to different cracks, thus improving its practicality. An electric push rod 16 is installed on the other side of the base plate 1. The output end of the electric push rod 16 passes through the base plate 1 and is connected to the mounting frame 17. A pressure roller 18 is rotatably installed inside the mounting frame 17. A telescopic rod 120 is installed at the upper end of the base plate 1 and connected to the mounting frame 17. The electric push rod 16 pushes the lower mounting frame 17 downward, causing the pressure roller 18 to press the material during the rolling process, thereby achieving the repair of cracks.

[0017] Preferably, a fan 19 is installed on the front side of the base plate 1, and an air pipe is provided at the bottom of the base plate 1. Several air ports 110 are installed at the lower end of the air pipe. The fan 19 cleans the dust and impurities in the ground cracks through the air ports 110 to avoid affecting the subsequent repair effect. A battery pack 112 is installed on the other side of the upper end of the base plate 1 through a power box 111 to provide power and avoid the situation where there is no power supply when connected to the outside.

[0018] Working principle: In use, first connect the solenoid valve 9, motor 13, electric push rod 16, fan 19 to the controller 4, and connect them to the battery pack 112. Then, input the raw material into the storage box 6 through the feed port 7. The motor 13 drives the rotating shaft 11 to make the stirring rod 12 stir the raw material. Before feeding, the fan 19 blows out the dust and impurities in the crack through the air port 110. With the solenoid valve 9 open, the discharge port 8 can be fed downward through the telescopic tube 10 and the feeding port 15. The pulling rod 14 slides on the sliding rod 114 through the slider 115, so that the feeding position of the feeding port 15 can be adjusted left and right. Under the action of the rotating connecting hole 118 and the rotating connecting block 119, the rotating plate 117 can be rotated to adjust the feeding angle of the feeding port 15. After feeding is completed, the electric push rod 16 pushes the pressure roller 18 at the lower end of the mounting frame 17 to roll downward, and the raw material is pressed during the movement, thus completing the work.
