Description
Technical Field
[0001] The utility model relates to the technical field of road surface crack repair, in particular to a highway road surface defect repair device. Background Art
[0002] Asphalt pavement is a variety of road surfaces paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. However, after long-term use, asphalt pavement will cause diseases due to rain erosion or excessive vehicle load. The most common disease is cracks in asphalt pavement. Such cracks not only affect the appearance of the road surface, but may also affect the driving of vehicles and increase the occurrence of traffic accidents. Therefore, cracks in highway asphalt pavement need to be repaired in time.
[0003] A Chinese utility model patent with publication number CN218492238U discloses a device for repairing cracks in asphalt roads, wherein a compression plate is slidably provided at the bottom end of the carrier, and the compression plate can be pressed on the cracks in the asphalt road, and a closed space is formed on the inner side of the crack by the compression of the compression plate. An injection pipe is detachably connected to the inner central position of the top end of the compression plate through a thread, and the cracks are repaired by injection of the injection pipe. Leakage holes are evenly opened on the inner side of the compression plate, and a block or a sleeve can be spirally connected to the inner side of the leakage hole.
[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the above-mentioned device is used, the compression plate is pressed tightly against the inner side of the crack to form a closed space, and then the crack is repaired by injecting material through the injection pipe. During this process, when the repair is completed, the staff cannot confirm whether the repair is completed in the closed space, which leads to the probability of over-grouting or under-grouting during the work process, so that the staff need to manually fill the slurry, thereby reducing the work efficiency of the staff. Utility Model Content

In this process, the mounting rod reduces the probability that the fixing rod follows the threaded rod to rotate, thereby improving the stability of the device.
[0014] Furthermore, a motor is fixedly provided on the bottom surface of the support plate, the output shaft end of the motor passes through the support plate, a first gear is fixedly provided on the output shaft end of the motor, a second gear is fixedly provided on the upper surface of the threaded rod, and the first gear and the second gear are meshed with each other.
