Description

Technical Field

[0001] This utility model relates to the field of asphalt road construction technology, specifically to a hot compaction device for asphalt road construction. Background Technology

[0002] Asphalt pavement is a common road surface material composed of asphalt, aggregate, and other additives. This material has many advantages and is suitable for various road conditions. Asphalt pavement has good waterproof performance. Due to the high sealing properties of asphalt itself, it can effectively prevent water from penetrating to the underside of the pavement. This helps prevent water damage to the pavement structure and reduces problems such as mud. Asphalt pavement construction is relatively simple. During construction, asphalt can be laid by hot mixing or cold processing, making it suitable for various road sizes and usage environments. When laying asphalt pavement, the laid asphalt mixture needs to be compacted.

[0003] When compacting asphalt roads, asphalt particles gradually stick to the surface of the compaction drum due to excessive temperature. As more and more asphalt adheres to the outer wall of the drum, it affects the condition of the road surface after compaction. During the compaction process, workers are not clear about the exact path the drum should follow, causing the drum to repeatedly compact the road, thus prolonging the construction time. Furthermore, the compacted road surface may be uneven, which is not easily noticeable to the public. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 7This utility model provides a technical solution: a hot compaction device for asphalt road construction, comprising a vehicle body 1, a control room 2 fixedly connected to the top of the vehicle body 1, a water tank 3 fixedly connected to the upper edge of the vehicle body 1, first wheel discs 7 rotatably connected to the inner sides of the left and right sides of the vehicle body 1, a common compaction wheel 8 fixedly connected to the middle of the two first wheel discs 7, cylindrical cylinders 9 fixedly connected to both sides of the vehicle body 1, second wheel discs 10 rotatably connected to one end of the two cylindrical cylinders 9, and a common hollow brush fixedly connected to the middle of the two second wheel discs 10. 11. A common transmission belt 12 connects the first wheel 7 and the second wheel 10 in the middle. A handwheel 13 is rotatably connected to the top of the middle of one side of the vehicle body 1. Two crossbars 19 are fixedly connected to one side of the vehicle body 1. Scrapers 14 are slidably connected to the outer side of the crossbars 19. A fixed rod 15 is rotatably connected to the bottom of one side of the vehicle body 1. A drum wheel platform 16 is rotatably connected to the bottom end of the fixed rod 15. Water balls 17 are fixedly connected to the top two edges of the drum wheel platform 16. A water inlet is opened at the top of the water tank 3. Soft water pipes 4 are connected to the bottom of both sides of the water tank 3. Two cylindrical tubes 9 are connected to two soft water pipes 4 respectively. The outer wall of the hollow brush 11 has multiple through holes arranged in a circular array. The hollow brush 11 and the second wheel 10 are connected at the middle to the cylindrical tubes 9. The hollow brush 11 is in contact with the top of the outer wall of the rolling wheel 8, and the scraper 14 is in contact with one side of the outer wall of the rolling wheel 8. The scraper 14 has an internal thread groove in its middle. The outer wall of the handwheel 13 has external threads, and the external thread of the handwheel 13 is rotatably connected to the internal thread groove of the scraper 14. Through the arrangement of the hollow brush 11, scraper 14, and water tank 3, this device... It has the functions of cleaning the asphalt adhering to the surface of the roller 8 and cooling the roller 8. Through the coordinated setting of the hollow brush 11 and the scraper 14, when the roller 8 rotates during use, the scraper 14 can scrape off the asphalt on the surface of the roller 8, and drive the hollow brush 11 to brush the surface of the roller 8 for secondary cleaning. The hollow brush 11 can also spray water droplets from the water tank 3 onto the surface of the roller 8, thereby achieving the purpose of double cleaning of the roller 8 and avoiding the roller 8 temperature from getting too high, so that more asphalt adheres to the surface of the roller 8.

[0030] Operators in control room 2 guide vehicle 1 to the construction site to compact the asphalt road. Then, they rotate handwheel 13, causing the scraper blade 14 on the outer wall of crossbar 19 to move back and forth, thus controlling the distance between the scraper blade 14 and the compaction wheel 8. This ensures the scraper blade 14 is in closer contact with the compaction wheel 8, resulting in more thorough scraping of asphalt from its surface. Meanwhile, water is added to the water tank 3 through its inlet, allowing the soft water pipe 4 to guide the water from the water tank 3 into the cylindrical tube 9, which then enters the hollow brush 11. As vehicle 1 moves, the compaction... The roller 8 rolls forward, causing the first discs 7 on both sides of the roller 8 to rotate. Then, the first discs 7 drive the second disc 10 to rotate via the outer conveyor belt 12, so that the hollow brush 11 can sweep away the asphalt remaining on the surface of the roller 8 that has not been completely scraped off. While the hollow brush 11 is rotating and sweeping the surface of the roller 8, water inside the hollow brush 11 overflows from the holes in the outer wall of the hollow brush 11 and is sprayed on the surface of the roller 8 to cool the outer wall of the roller 8 and prevent more asphalt from sticking to the roller 8 when the temperature is too high, thus affecting the compaction work of road construction.

A fixed rod 15 is rotatably connected to the bottom of one side of the vehicle body 1. A drum wheel platform 16 is rotatably connected to the bottom end of the fixed rod 15. Water balls 17 are fixedly connected to both sides of the top of the drum wheel platform 16. Two extension blocks 5 are fixedly connected to the bottom front side of the vehicle body 1. The two extension blocks 5 are right-angled triangles. Multiple first... Infrared lamp heads 6, multiple first infrared lamp heads 6 are placed on the triangular inclined surface of extension block 5, and the multiple first infrared lamp heads 6 are arranged in a linear array. The distance between the two extension blocks 5 is consistent with the lateral length of the rolling wheel 8. The water ball 17 is composed of transparent tempered glass and internal water, and the water volume inside the water ball 17 accounts for half of the internal volume of the water ball 17. Multiple second infrared lamp heads 18 are fixedly connected to one side bottom of the roller platform 16, and the multiple second infrared lamp heads 18 are arranged in a linear array. Through the first infrared lamp heads 6, the second infrared lamp heads 18, and the water ball 17 The device is designed to plan the compaction path and detect the smoothness of the compacted road. Through the coordinated use of the first infrared lamp 6 and the second infrared lamp 18, the first infrared lamp 6 illuminates the road surface in front, allowing workers to clearly see the outer edge of the path that the compaction wheel 8 will soon pass over. The second infrared lamp 18 and the water balloon 17 behind it allow workers to assess the road's smoothness by observing the infrared illumination and the horizontal position of the water source within the water balloon 17, thus assisting in road compaction and planning.

[0033] Before compacting the asphalt road, the worker turns on multiple first infrared lamps 6 on the inclined surface of the extension block 5 on one side of the vehicle body 1. The spacing of the extension blocks 5 is aligned with the lateral width of the compaction wheel 8, ensuring the first infrared lamps 6 illuminate the road ahead. This allows the worker to visually see the path the compaction wheel 8 will soon pass over, enabling them to plan the compaction path. After compaction, the worker can observe the water level in the water sphere 17 at the top of the rear cylindrical wheel platform 16 of the vehicle body 1 to determine if the road surface compacted by the compaction wheel 8 is smooth. When the water level in the water sphere 17 deviates, the vehicle body 1 is currently in an uneven position. The vehicle body 1 is then moved again to level the water level in the water sphere 17, and the second infrared lamp 18 is turned on to illuminate the road surface behind the vehicle body 1. The raised, uneven parts of the road surface behind the vehicle body 1 are illuminated by the infrared light emitted by the second infrared lamp 18, while the recessed parts form a concave shape with the second infrared lamp 18.
