Description

Technical Field

[0001] The utility model relates to the technical field of road crack repair, in particular to a road surface crack grouting device. Background Art

[0002] Pavement refers to a layered structure that is paved on the roadbed with various road-building materials and directly bears vehicle loads. A good quality pavement should have sufficient strength and good stability, and its surface should meet the requirements of flatness, density and anti-skid. The pavement structure consists of a surface layer, a base layer and a cushion layer. When the pavement is unevenly stressed or encounters heavy loads, cracks will appear in the boundary part. These pavement cracks will affect driving, so they need to be repaired by grouting. During the treatment process, a pavement crack grouting equipment is often used for repair.

[0003] Announcement No. CN220450632U discloses a road crack grouting device, comprising a movable box and a scraper assembly for pushing the excess slurry sprayed from the box into the cracks. The utility model has the beneficial effect of providing a scraper assembly to push the excess slurry sprayed from the nozzle into the road cracks, thereby greatly improving the efficiency of the slurry in repairing the road cracks, ensuring that the excess slurry will not accumulate on the road surface and affect the passage of vehicles, while also improving the efficiency of road repair.

[0004] 1. The grouting head height of the existing pavement crack grouting device is often fixed. When repairing pavement cracks, the grouting head cannot be extended into the cracks. The slurry can only be filled from the cracks in the surface layer of the ground. The cracks deep below the surface are difficult to fill with slurry, resulting in incomplete crack repair. Therefore, the repair slurry may fall on the road surface on both sides of the crack, resulting in a waste of repair slurry.

[0005] 2. The existing pavement crack grouting device does not have a structure for cleaning road cracks, resulting in a lot of impurities in the cracks during grouting, which affects the adhesion between the slurry and the walls on both sides of the cracks, and affects the quality of crack repair. Therefore, we propose a pavement crack grouting device to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7 , the utility model provides an embodiment: a pavement crack grouting device, comprising a cart 1;

[0031] Four sets of wheels 2 are installed at the lower end of the cart 1, a storage tank 3 is installed at the right end of the cart 1, a feeding port 4 is provided at the upper end of the storage tank 3, a grouting pump 7 is installed at the left side of the lower end of the storage tank 3, a connecting pipe 8 is installed at the left end of the grouting pump 7, and the first grouting pipe 9 and the second grouting pipe 10 are respectively installed at the lower ends of the connecting pipe 8, a groove 11 is provided at the cart 1, an adjusting component is installed at the left end of the cart 1, and the lower ends of the first grouting pipe 9 and the second grouting pipe 10 are installed in the adjusting component. The device is moved by the cart 1, and the repair material in the storage tank 3 is sucked out by the grouting pump 7 and the connecting pipe 8, and then injected into the cracks of the road through the first grouting pipe 9 and the second grouting pipe 10, and the lower ends of the first grouting pipe 9 and the second grouting pipe 10 are adjusted by the adjusting component;

[0032] Furthermore, a motor 5 is installed at the upper end of the storage tank 3, and a stirring blade 6 is installed at the output end of the motor 5. The lower end of the stirring blade 6 is inserted into the storage tank 3. This structure drives the stirring blade 6 to rotate in the storage tank 3 through the motor 5 to prevent the repair material in the storage tank 3 from solidifying.

[0033] Furthermore, the lower end of the first grouting pipe 9 is lower than the lower end of the second grouting pipe 10. This structure allows the repair material to be injected into the road cracks in two layers according to the lower end heights of the first grouting pipe 9 and the second grouting pipe 10, thereby improving the quality of road crack repair.

[0034] Furthermore, the adjustment component includes a transverse plate 12, which is fixedly mounted on the left end of the trolley 1, a lifting component 13 is mounted on the transverse plate 12, a mounting plate 14 is mounted in the groove 11, the lower end of the lifting component 13 is connected to the left end of the mounting plate 14, and two groups of through holes 15 are opened at the right end of the mounting plate 14, and the lower ends of the first grouting pipe 9 and the second grouting pipe 10 are inserted into the two groups of through holes 15. The structure moves the mounting plate 14 up and down by rotating the lifting component 13, thereby inserting the lower ends of the first grouting pipe 9 and the second grouting pipe 10 into the crack.

[0035] Furthermore, fixed rods 16 are symmetrically installed at the front and rear ends of the right end of the mounting plate 14, and sliders 17 are installed on the opposite sides of the upper ends of the two groups of fixed rods 16. Two groups of guide plates 18 are installed on the cart 1, and slide grooves 19 are provided in the opposite sides of the two groups of guide plates 18.

[0038] Furthermore, the multiple groups of air ducts 22 are arranged in sequence from front to back. The installation positions of the multiple groups of air ducts 22 in this structure ensure that when the multiple groups of air ducts 22 move to the right with the cart 1, it is possible to ensure that the wind blowing on the road is increased.

[0039] Furthermore, the mounting plate 14 is made of transparent tempered glass. This structure allows the staff to check the injection conditions of the first grouting pipe 9 and the second grouting pipe 10 on the road cracks through the mounting plate 14 according to the material of the mounting plate 14 .
