Description

Technical Field

[0001] The utility model relates to the technical field of local road surface repair devices, in particular to a device for repairing and leveling local potholes on a road surface. Background Art

[0002] Asphalt pavement, cement pavement or cement floor will be partially broken, pitted and cracked after long-term vehicle pressure or heavy object impact. In order to ensure the safety of vehicles and pedestrians, these locally damaged parts need to be repaired.

[0003] At present, for the local repair of this kind of road surface, manual repair and smoothing are mostly adopted, and the repair efficiency is low. In recent years, some road pothole repair devices have been developed that can use artificial filler injection and then roll the road surface to level the road surface. Since hollows or uneven distribution of sand and cement slurry may occur during filler injection, a device that simply uses a roller to flatten the road surface cannot solve the above problems well (after the hollow area is flattened, the road surface in this area will sink, and the road surface with uneven distribution of sand and cement slurry cannot withstand the reciprocating rolling of vehicles and has a short service life).

[0004] In view of the above problems, the inventors proposed a device for repairing and smoothing local potholes on the road surface. Summary of the invention

[0005] The utility model aims to provide a road surface local pothole repair and leveling device, which can effectively reduce the hollowing of the grouting slurry and the uneven distribution of the slurry and sand and gravel, and solve the problems raised in the background technology.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a road surface local pothole repair and smoothing equipment, including a base plate 2 and a frame, a slurry tank 1 is arranged directly above the base plate 2, a repair and smoothing mechanism is arranged directly below the base plate 2, the slurry tank 1 and the base plate 2 are fixedly connected by an alloy tube 5, and the discharge end of the alloy tube 5 extends to the bottom of the base plate 2 and does not contact the repair and smoothing mechanism, a main shaft 3 is fixed at the center of the repair and smoothing mechanism, a scraper 4 is fixedly arranged on the main shaft 3, and a retractable rake tooth 91 is installed inside the scraper 4, the top of the main shaft 3 is rotatably connected to the base plate 2, and the top of the main shaft 3 is rotatably installed in the middle of the bottom of the base plate 2 through a bearing.

[0024] like Figure 1 As shown, the frame includes a bracket 6 fixedly connected to the slurry tank 1, and one end of the bracket 6 away from the slurry tank 1 is bent downward and fixedly connected to a threaded rod 61, and the threaded rod 61 is threadedly connected to an internally threaded sleeve 7, and the inner wall of the internally threaded sleeve 7 is provided with a threaded groove adapted to the threaded rod 61. The height of the device can be adjusted by rotating the internally threaded sleeve 7, so that it is suitable for the repair needs of local road surfaces at different heights. An integrally formed bottom plate 71 is provided at the bottom of the internally threaded sleeve 7, and the bracket 6 and the base plate 2 are fixedly connected by a pull rod 12. The provision of the pull rod 12 enhances the firmness of the device.

[0025] like Figure 1 As shown, at least three groups of frames are provided, and the three groups of frames are arranged in a ring shape on the periphery of the base plate 2, with good supporting stability.

[0026] like Figure 1 As shown, an injection port 8 is provided on the top of the slurry tank 1, and external raw materials such as cement mortar are injected into the slurry tank 1 through the injection port 8 for temporary storage. Alloy tubes 5 are evenly arranged on the bottom of the slurry tank 1, and at least four alloy tubes 5 are arranged. Multiple alloy tubes 5 are arranged so that the slurry can be evenly poured at various places of the repair position to facilitate later leveling.

[0027] like Figure 1 and Figure 4 As shown, at least three scrapers 4 are provided, and the three scrapers 4 are distributed in a circular array and fixed on the side wall of the main shaft 3. Through holes for the rake teeth 91 to pass through are evenly opened at the bottom of the scraper 4, and the outer wall surface of the rake teeth 91 and the inner wall surface of the through hole are tightly fitted.

[0028] like Figure 4 As shown, a tooth seat 9 is assembled inside the scraper 4, and rake teeth 91 are evenly arranged at the bottom of the tooth seat 9. The tooth seat 9 and the top of the scraper 4 are connected by a cylinder 10. Guide rods 11 are fixed to the scraper 4 on both sides of the cylinder 10.

A row of rake teeth 91 is then started so that the rake teeth 91 rotate continuously, thereby stirring the initially smoothed slurry, reducing hollowing, and reducing the uneven distribution of sand and slurry. Then, close the cylinder 10, drive the tooth seat 9 to rise until the lower end surface of the rake teeth 91 is flush with the lower end surface of the scraper 4, and the scraper 4 continues to rotate to continue to smooth the slurry.

[0032] When in use, the height of the device can be adjusted by rotating the internal thread sleeve 7, thereby adjusting the height of the wiping surface, and the device has wide applicability.
