Technical Field

[0001] This utility model relates to the field of highway maintenance technology, specifically to a crack repair and flattening device for highway maintenance. Background Technology

[0002] With the continuous expansion of my country's highway network and the increase in its service life, highway pavements are prone to various cracks and defects under the influence of long-term loads, environmental changes, and material aging. If these cracks are not treated in time, they will accelerate the damage to the pavement structure, affect driving safety and comfort, and shorten the service life of the highway.

[0003] In the existing technology, conventional repair methods for highway cracks mainly rely on manual or semi-mechanized equipment for filling and compaction. The operation process is usually divided into several independent steps: first, the crack is cleaned, then the repair material is poured in manually or with simple tools, and finally a special flattening device is used to roll and flatten the filled area. The efficiency is low, and the discharge port size of some repair tools is fixed, which is inconvenient to adjust according to the actual repair needs. Utility Model Content

Rollers 2 rotatably disposed on both sides of the main body 1 are fixedly connected to both ends of the first connecting shaft 201. The device also includes a repair mechanism 4 and a rolling mechanism 6. The repair mechanism 4 is installed on the main body 1, and the rolling mechanism 6 is installed at the rear end of the main body 1 for rolling the repair material for filling the ground.

[0026] like Figure 2 , 3As shown in Figure 5, the repair mechanism 4 includes a storage tank 401, a pump 405, and an adjustment component 5. The upper end of the main body 1 has an installation groove 101, in which the storage tank 401 is installed. The main body 1 has an inner cavity 104 located at the front, extending through the lower end of the main body 1. The adjustment component 5 is symmetrically installed in the inner cavity 104 and adjusts the size of the lower opening of the inner cavity 104. The pump 405 is fixedly connected to the upper end of the main body 1 to transport repair material from the storage tank 401 to the inner cavity 104. The inner cavity 104 has an inclined curved surface extending to its lower opening. Both ends of the pump 405 are fixedly connected to… There is a material conveying pipe 406, one end of which is fixedly connected to and connected to the storage tank 401, and the other end of which is fixedly connected to the upper end of the main body 1 and connected to the middle of the inner cavity 104. The upper end of the storage tank 401 is provided with a material inlet 402, and a box cover 403 is fastened to the upper end of the storage tank 401. The lower end of the box cover 403 is fixedly connected with a sealing plug 404 that is inserted and matched with the material inlet 402. After the repair material is drawn from the bottom of the storage tank 401 by the pump 405 through the material conveying pipe 406, the material is introduced into the inner cavity 104. Under the action of the pump 405, the repair material is discharged from the lower end of the main body 1 to the ground for repair.

[0027] like Figure 1 , 3 As shown in Figures 4 and 6, the adjusting assembly 5 includes an adjusting rod 501 and an adjusting plate 504. The adjusting plate 504 is horizontally slidably fitted in the inner cavity 104. One end of the adjusting rod 501 is fixedly connected to a limiting piece 503 and rotatably connected to the outside of the adjusting plate 504 through the limiting piece 503. Connecting rings 106 are symmetrically fixedly connected to both sides of the main body 1. The other end of the adjusting rod 501 rotatably extends out of the outside of the main body 1 and is threadedly connected to the connecting ring 106. A knob 502 is fixedly connected to the other end of the adjusting rod 501. A strip-shaped scraper 507 is fixedly connected to the inner side of the adjusting plate 504. The strip-shaped scraper 507 slides against the inner wall of the inner cavity 104, and the cross-section of the strip-shaped scraper 507 is set at a right angle. The main body 1 is triangular, with a discharge funnel 105 connected to the lower part of the inner cavity 104. A limit plate 505 and an index plate 506 are symmetrically fixed to the lower end of the adjusting plate 504. The adjusting plate 504 and the index plate 506 are respectively slidably attached to both sides of the discharge funnel 105. The front end of the main body 1 is provided with a scale line. The upper end of the adjusting plate 504 is set with a triangular structure and marked at the bottom of the scale line. According to the repair needs, the knobs 502 on both sides of the main body 1 are rotated, thereby pushing the corresponding adjusting plate 504 to move horizontally in the inner cavity 104. The distance between the adjusting plate 504 and the inner cavity 104 is controlled by the sliding of the index plate 506 below the scale line, so as to realize the width adjustment of the repair material discharge.

[0028] like Figure 2-4As shown, the rolling mechanism 6 includes a mounting frame 601 and a roller 603. The mounting frame 601 is fixed to the rear end of the main body 1 by bolts. Second bearings 602 are installed on both sides of the mounting frame 601. The roller 603 is rotatably disposed in the mounting frame 601. Second connecting shafts 604 are fixed to both ends of the roller 603. The second connecting shafts 604 are inserted into the second bearings 602. After the repair material is discharged to the ground, the roller 603 is used to roll the material on the ground.

[0029] In use, the repair material is introduced into the storage box 401 through the feed inlet 402. According to the repair width requirements, the knobs 502 on both sides of the main body 1 are rotated, which in turn pushes the parallel adjustment plates 504 in the inner cavity 104 to slide in the inner cavity 104, adjusting the distance between the two adjustment plates 504. When the adjustment plates 504 move, the index plate 506 moves horizontally at the lower end of the scale. The distance between the two adjustment plates 504 is precisely adjusted by the scale corresponding to the two index plates 506. Then, the pump 405 drives the conveying pipe 406 to draw the repair material from the storage box 401 and export the material to the inner cavity 104. The repair material is exported to the ground from the discharge funnel 105 at the lower end of the inner cavity 104 for repair. The main body 1 is pushed and the roller 2 moves to make the roller 603 roll the repair material on the ground to compact the repair material on the ground.
