Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of asphalt pavement repair devices, specifically relating to a highly applicable on-site rapid repair device for asphalt pavements. Background Technology
[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. Asphalt pavement is a road paved with asphalt. Asphalt reducing agent is a cold-mix reducing agent containing polymer active substances. It can completely penetrate into the pores and microcracks of asphalt concrete, penetrate, bond, and repair asphalt, and activate asphalt adhesive, thereby achieving the effect of repairing asphalt pavement.
[0003] In asphalt pavement repair projects, repair equipment is used to conveniently deliver asphalt to cracked areas for repair. However, a key issue exists when using repair equipment: when asphalt is stored in the mixing tank, a layer of asphalt often adheres to the inner wall of the tank. If this adhered asphalt layer is not treated promptly and effectively, it will lead to a series of adverse consequences during subsequent use. Specifically, this adhered asphalt layer not only wastes materials but may also affect the uniform mixing of asphalt within the mixing tank, thereby reducing the quality of the repair material. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please see Figure 1-4 This utility model provides the following technical solution: a highly applicable on-site rapid repair device for asphalt pavement, including a frame 1 and a blower 3, a heat preservation tank 5, a push handle 2, a compaction mechanism 4 and a control cabinet 8 mounted on the top of the frame 1. A mixing tank 6 is fixedly connected inside the heat preservation tank 5. A mixing mechanism 7 is installed inside the mixing tank 6. A discharge pipe 14 is connected to the bottom of the mixing tank 6. A control valve 15 is installed on the surface of the discharge pipe 14. The compaction mechanism 4 includes a support plate 41, an electric cylinder 42, a mounting frame 43 and a compaction roller 44. The mixing mechanism 7 includes a mixing motor 71, a reducer 73, a mixing rod 72 and a bearing 74. The bearing 74 is mounted on one end of the mixing rod 72. The output shaft of the mixing motor 71 is connected to the reducer 73. The reducer 73 is connected to the other end of the mixing rod 72. A scraper 9 is installed at the end of the mixing rod 72.
[0023] In a preferred embodiment: the scraper 9 is attached to the inner wall of the mixing tank 6 via the stirring rod 72, and the scraper 9 is arc-shaped to fit the inner wall of the mixing tank 6.
[0024] In a preferred embodiment, the scraper 9 is rotatably connected to the mixing tank 6 via the stirring rod 72.
[0025] In this embodiment, the operation of the asphalt pavement repair device is as follows: The device is manually pushed to the crack or pothole in the asphalt pavement. Then, the control valve 15 is opened, allowing asphalt to flow smoothly from the mixing tank 6 through the discharge pipe 14, directly applying it to the crack for rapid on-site repair. Furthermore, the device has a compact overall structure, facilitating transportation and operation, and is suitable for single or double-person operation.
[0026] Secondly, to improve the convenience and accuracy of operation, a through hole is designed on the surface of the frame 1, allowing workers to clearly observe the flow of asphalt and manually close the discharge pipe 14 as needed. When manually closing the pipe, precautions must be taken to avoid burns from the heat of the asphalt. Furthermore, this design avoids operational inconvenience caused by the frame 1 obstructing the view, ensuring the smooth progress of the repair work.
[0027] Next, the operator manually activates the compaction mechanism 4 via control cabinet 8, which is electrically connected to the compaction mechanism 4. The telescopic end of the electric cylinder 42 extends, pushing the mounting frame 43 and the compaction roller 44 connected to the mounting frame 43 to descend and contact the road surface, thus compacting the repaired asphalt pavement. The compaction roller 44 is rotatably connected to the mounting frame 43, ensuring the smoothness and durability of the road surface. During this process, the operator needs to control the vehicle frame 1 to move back and forth, allowing the compaction roller 44 to move back and forth across the repaired asphalt pavement. Then, the telescopic end of the electric cylinder 42 is connected to the mounting frame 43 via bolts, providing a replaceable compaction tool suitable for cracks of different widths and depths.
[0028] Next, the mixing mechanism 7 is manually started via control cabinet 8, which is electrically connected to the mixing mechanism 7. The output shaft of the mixing motor 71 then drives the reducer 73 to start working. The reducer 73 further drives the mixing rod 72 to rotate along the inner ring of the bearing 74. This rotation not only drives the mixing process but also drives the scraper 9 to rotate. The two ends of the scraper 9 are designed with bevels to form scraping blades, which greatly improves the effect of scraping off the asphalt layer adhering to the inner wall of the mixing tank 6 and effectively avoids the waste of asphalt material.
[0029] Furthermore, the synergistic effect of the scraper 9 and the mixing mechanism 7 brings another significant advantage: improved uniformity of asphalt mixing. The rotational motion of the scraper 9 ensures that the asphalt is more thoroughly mixed within the mixing tank 6, further enhancing the quality of asphalt repair.
[0030] Example 2
[0031] Please see Figure 1-4 Two symmetrical guide rails 10 are installed at the bottom of the frame 1, and a receiving box 11 is slidably connected to the surface of the guide rails 10.
[0032] In a preferred embodiment: a mounting block 12 is installed at the bottom of the frame 1, and an electric rod 13 is installed on the side wall of the mounting block 12.
[0033] In a preferred embodiment, the size of the receiving box 11 is larger than the size of the through opening on the surface of the frame 1.
[0034] In a preferred embodiment, the receiving box 11 is telescopically connected to the frame 1 via an electric rod 13.
[0035] In this embodiment, the electric boom 13 is manually activated via the control cabinet 8, which is electrically connected to the electric boom 13. After the telescopic end of the electric boom 13 extends, it pushes the receiving box 11 to slide smoothly along the surface of the guide rail 10. As the receiving box 11 moves, it blocks the through hole on the surface of the frame 1 and is located at the bottom of the discharge pipe 14. This design ensures that any dripping asphalt inside the discharge pipe 14 can be promptly collected by the receiving box 11 when the pipe is closed, effectively preventing asphalt waste. In this way, the equipment not only achieves the recycling of residual material but also further improves its environmental performance and resource utilization efficiency.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
