Description
Technical Field
[0001] This utility model belongs to the technical field of road construction, and in particular relates to a fine surface treatment device for asphalt pavement. Background Technology
[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt materials into mineral aggregates. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade road surfaces in road construction. Asphalt pavement is formed by spreading and compacting asphalt concrete. Asphalt concrete is a mixture made by thoroughly mixing asphalt materials with a certain viscosity and appropriate quantity with mineral aggregates of a certain gradation. However, the following drawbacks exist in the fine surface treatment of asphalt pavement:
[0003] Currently, the paving of asphalt pavement mostly involves laying a concrete pavement underneath before laying the asphalt pavement. However, this method is not perfect for the fine treatment of the asphalt pavement, and the adhesion between the asphalt pavement and the underlying concrete pavement is generally poor and needs further improvement.
[0004] Secondly, asphalt pavement is usually laid directly on concrete pavement and then compacted by machinery such as road rollers. However, with long-term use, the pavement will develop problems such as cracks and water seepage. Conventional modified asphalt paving methods can still be further optimized. Utility Model Content
[0005] The purpose of this utility model is to provide a fine surface treatment device for asphalt pavement. By setting up a frame, storage component one, spray pipe, material box, paving shell, trapezoidal transfer shell, pressure roller, storage component two, and vibration motor, it solves the problems of poor adhesion between conventional asphalt pavement and the underlying concrete pavement, as well as the problems of cracks and water seepage that still occur in modified asphalt pavement.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a fine surface treatment device for asphalt pavement, including a frame, a storage component one, a material distribution box, a storage component two, an air compressor, and a spray pipe. The frame is equipped with storage component one and storage component two, and the material distribution box is fixed in the frame between storage component one and storage component two. The bottom of the material distribution box is fixed with a discharge channel, and the bottom of the material distribution box is also fixed with a trapezoidal transfer shell. A paving shell is fixed through the inclined surface of the trapezoidal transfer shell, and a pressure roller is provided on the side of the paving shell away from the trapezoidal transfer shell.
[0008] Two symmetrical ear plates are fixed on the bottom edge of the frame near the storage component. A blow pipe is fixed inside the two ear plates, and an air nozzle is fixed at equal intervals and at an angle through the lower part of the blow pipe.
[0009] The storage assembly includes a storage box fixed inside the frame, with equidistantly distributed discharge pipes through the bottom of the storage box, and a nozzle fixed at the bottom end of the discharge pipe.
[0010] Furthermore, an electrically controlled valve is fixed outside the discharge pipe, and a through-inlet is provided at the top of the storage tank, with a cap screwed onto the outside of the inlet; the storage component one and storage component two have the same structural composition.
[0011] Furthermore, an air compressor is fixed to the upper end of the frame between the fabric box and the second storage component, and two air pipes are fixed to the air outlet end of the air compressor. The ends of the two air pipes away from the air compressor are respectively connected to the storage boxes in the first and second storage components.
[0012] Furthermore, a fabric shaft is rotatably connected inside the fabric box, and three rows of fabric sheets arranged in a circular array are fixed on the fabric shaft. A fabric motor is fixed on the outer wall of the fabric box, and the output shaft of the fabric motor is connected to the end of the fabric shaft for transmission.
[0013] Furthermore, a ramp is fixed at the bottom of the fabric box, and the fabric shaft is located near the lower end of the ramp. The fabric shaft is located above the connection between the discharge channel and the fabric box, and the outlet of the discharge channel faces into the trapezoidal transfer shell.
[0014] Furthermore, a vibrating motor is fixed to the upper end of the paving shell, and two bearings are also fixed to the paving shell next to the vibrating motor. The two bearings are rotatably connected to a rotating shaft. The two ends of the rotating shaft extend out of the bearings and are rotatably connected to ear plates two. The other end of the ear plates two away from the rotating shaft is rotatably connected to the end of the pressure roller. The pressure roller is located between the paving shell and the storage component two.
[0015] Furthermore, the longitudinal section of the paving shell has an inverted U-shaped structure, and the transverse section of the trapezoidal intermediate shell has a right-angled trapezoidal structure.
[0016] This utility model has the following beneficial effects:
[0017] This invention solves the problem of poor adhesion between conventional asphalt pavement and the underlying concrete pavement by setting up a frame, a storage component, a spray pipe, a material distribution box, a paving shell, and a trapezoidal transfer shell. During asphalt pavement paving, compressed air is first sprayed from the spray pipe to clean the concrete pavement. Tack coat oil is pre-stored in the storage component. After the pavement is cleaned, the tack coat oil in the storage component is sprayed onto the pavement. Then, the modified asphalt mixture is transferred from the material distribution box to the trapezoidal transfer shell, and finally into the paving shell, forming an asphalt pavement of the corresponding height. This operation results in a tighter adhesion between the asphalt pavement and the underlying concrete pavement, better stability, and prevents delamination.
[0018] This invention solves the problems of cracking and water seepage that still occur in modified asphalt pavements by setting up a pressure roller, a storage component two, a vibrating motor, and a paving shell, which can still be further optimized. After the asphalt pavement is laid, the asphalt is initially compacted by the vibration of the vibrating motor in the paving box, and then compacted a second time by the pressure roller to avoid excessive deformation during subsequent roller operation. After the pressure roller is pressed, the epoxy emulsified asphalt stored in the storage component two is sprayed onto the asphalt pavement. After spraying, an ultra-thin, wear-resistant protective layer is formed on the surface of the asphalt pavement. This setting can improve the performance of the asphalt pavement without reducing the anti-skid performance of the original pavement. At the same time, the epoxy emulsified asphalt gradually penetrates into the asphalt pavement, further bonding the mixture in the asphalt pavement, and even penetrating into the underlying concrete pavement, avoiding the problems of cracking and water seepage that still occur in modified asphalt pavement, increasing the degree of bonding, and making it more compact.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Please see Figures 1-5 As shown, this utility model is a fine surface treatment device for asphalt pavement, including a frame 1, a storage component 2, a material distribution box 3, a storage component 4, an air compressor 5, and a spray pipe 6. The storage component 2 and the storage component 4 are arranged inside the frame 1, and the material distribution box 3 is fixed inside the frame 1 between the storage component 2 and the storage component 4. The bottom of the material distribution box 3 is fixed with a discharge channel 301, and the bottom of the material distribution box 3 is also fixed with a trapezoidal transfer shell 302. A paving shell 303 is fixed through the outside of the inclined surface of the trapezoidal transfer shell 302, and a pressure roller 7 is arranged on the side of the paving shell 303 away from the trapezoidal transfer shell 302.
[0029] The frame 1 serves as the main installation unit, and its interior houses the storage component 2, the material distribution box 3, and the storage component 4. The storage box 201 in the storage component 2 stores tack coat oil, and the storage box 201 in the storage component 4 stores epoxy emulsified asphalt. The material distribution box 3 transfers the asphalt mixture, which is then discharged from the discharge chute 301 and accumulated in the trapezoidal transfer shell 302. As the entire device moves forward, the asphalt mixture in the trapezoidal transfer shell 302 enters the paving shell 303, forming a regular road surface with a certain thickness. Then, as the device moves forward, the pressure roller 7 performs preliminary compaction on the road surface paved by the paving shell 303.
[0030] Two symmetrical ear plates 101 are fixed on the bottom edge of the frame 1 near the storage component 2. A blow pipe 6 is fixed inside the two ear plates 101, and an air nozzle 601 is fixed through the lower part of the blow pipe 6 at equal intervals and at an angle.
[0031] Using ear plate 101, a blowpipe 6 is installed. Compressed air in the blowpipe 6 is sprayed from the air nozzle 601 onto the concrete pavement to clean it and prevent dust and impurities from affecting the subsequent asphalt pavement paving.
[0032] Storage component 12 includes a storage box 201 fixed inside the frame 1. The bottom of the storage box 201 is fixed with equidistantly distributed discharge pipes 204, and the bottom end of the discharge pipes 204 is fixed with a nozzle 206.
[0033] The storage box 201 stores the corresponding materials, which are sprayed out from the nozzle 206 under the discharge pipe 204 when needed.
[0034] An electric control valve 205 is fixed outside the discharge pipe 204. The top of the storage tank 201 is provided with a through inlet 202, and a cap 203 is screwed onto the outside of the inlet 202. The storage component 1 2 and the storage component 2 4 have the same structure.
[0035] The feed inlet 202 is used to add the required materials. After adding, it is sealed with a cap 203. When discharging, the discharge pipe 204 is controlled by an electric control valve 205.
[0036] An air compressor 5 is fixed at the upper end of the frame 1 between the fabric box 3 and the storage component 2 4, and two air pipes 501 are fixed at the air outlet end of the air compressor 5. The ends of the two air pipes 501 away from the air compressor 5 are respectively connected to the storage box 201 in the storage component 1 2 and the storage component 2 4.
[0037] The air compressor 5 supplies air to the storage tank 201 in the storage component 1 2 and the storage component 2 4 through the air pipe 501, which can both achieve pneumatic stirring of the materials inside and increase the pressure, so that the materials are sprayed out at high speed from the discharge pipe 204 when discharging.
[0038] A fabric shaft 305 is rotatably connected inside the fabric box 3, and three rows of fabric pieces 3051 arranged in a circular array are fixed on the fabric shaft 305. A fabric motor 304 is fixed on the outer wall of the fabric box 3, and the output shaft of the fabric motor 304 is connected to the end of the fabric shaft 305 for transmission.
[0039] The bottom of the material box 3 is fixed with a ramp 306, and the material shaft 305 is close to the lower end of the ramp 306. The material shaft 305 is located above the connection between the discharge channel 301 and the material box 3, and the outlet of the discharge channel 301 faces into the trapezoidal transfer shell 302.
[0040] The asphalt mixture entering the placing box 3 is guided along the ramp 306 to the placing shaft 305. The motor drives the placing shaft 305 and the surrounding placing plates 3051 to rotate, pushing the asphalt mixture into the discharge channel 301 until it is discharged from the discharge channel 301.
[0041] A vibratory motor 308 is fixed at the upper end of the paving shell 303. Two bearings 3031 are also fixed on the paving shell 303 next to the vibratory motor 308. The two bearings 3031 are rotatably connected to a rotating shaft 307. The two ends of the rotating shaft 307 extend out of the bearings 3031 and are rotatably connected to ear plates 3071. The other end of the ear plates 3071 away from the rotating shaft 307 is rotatably connected to the end of the pressure roller 7. The pressure roller 7 is located between the paving shell 303 and the storage component 4.
[0042] The asphalt mixture entering the paving shell 303 is vibrated by the vibrating motor 308, which can effectively carry out the initial compaction operation to form a regular road surface. It is then further pressed by the pressure roller 7 connected by the end ear plate 3071 of the rotating shaft 307 to form secondary compaction. Finally, the epoxy emulsified asphalt in the storage component 4 is sprayed out, sprayed onto the road surface and seeps in, and is finally compacted by the road roller.
[0043] The longitudinal section of the paving shell 303 has an inverted U-shaped structure, and the transverse section of the trapezoidal intermediate shell 302 has a right-angled trapezoidal structure.
[0044] The specific working principle of this utility model is as follows: First, the device is moved to the concrete road surface where asphalt pavement needs to be laid. It is moved by external equipment, with the direction of movement from the storage component 2 towards the spray pipe 6. The spray pipe 6 is installed under the frame 1 using the ear plate 101. Compressed air in the spray pipe 6 is sprayed onto the concrete road surface through the air nozzle 601 to clean it. Tack coat oil is stored in the storage tank 201 of the storage component 2 (added through the inlet 202 after opening the cover 203, and closed after addition). After the road surface is cleaned, the tack coat oil in the storage component 2 is sprayed onto the road surface. The air compressor 5 circulates air through the air pipe 501 into the storage tank 201 of the storage component 2, which can both pneumatically agitate the internal materials and increase the pressure. During discharge, the electric control valve 205 is opened, and the material is sprayed at high speed from the discharge pipe 204 through the nozzle 206. The asphalt mixture then enters the distribution box 3 and flows along the slope 30... At the guide shaft 305, a motor drives the shaft and its surrounding fabric strips 3051 to rotate, pushing the asphalt mixture into the discharge channel 301 until it is discharged from the discharge channel 301 and accumulates in the trapezoidal transfer shell 302. As the entire device moves forward, the asphalt mixture in the trapezoidal transfer shell 302 enters the paving shell 303, where it is vibrated by the vibrating motor 308, effectively performing preliminary compaction to form a regular road surface. It is then further pressed by the pressure roller 7 connected by the end ear plate 3071 of the rotating shaft 307, forming secondary compaction. Finally, the epoxy emulsified asphalt stored in the storage component 4 is sprayed onto the asphalt road surface. After spraying, an ultra-thin, wear-resistant protective layer is formed on the surface of the asphalt road surface. This setting can improve the performance of the asphalt road surface without reducing the anti-skid performance of the original road surface. At the same time, the epoxy emulsified asphalt will gradually penetrate into the asphalt road surface, further bonding the mixture in the asphalt road surface.

Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
