Description

Technical Field

[0001] This utility model belongs to the field of asphalt mixture construction technology, specifically relating to an asphalt mixture repair mixing and paving device that can be used for both hot and cold mixing. Background Technology

[0002] Asphalt pavement, as an important component of modern road construction, is widely used due to its excellent driving comfort, low noise, and good durability. However, due to the continuous effects of traffic loads, temperature changes, and environmental factors (such as rainwater erosion), asphalt pavement inevitably develops problems such as cracks and potholes. If these problems are not repaired in time, they will not only exacerbate the damage to the pavement but may also cause traffic accidents, seriously threatening driving safety.

[0003] Traditional asphalt pavement repair methods mainly rely on manual operation, using simple tools (such as shovels, rakes, and road rollers) for repair. This method requires less equipment investment and is suitable for various small-scale, irregular pavement damage areas. Workers can also manually adjust the amount of repair material and the degree of compaction according to the damage to ensure the repair effect. However, traditional manual repair methods have limitations such as long time consumption, unstable repair quality, high labor intensity, and high labor costs.

[0004] To improve repair efficiency and quality, the industry has gradually introduced mechanized repair equipment. However, most existing emergency road repair equipment is designed for single-type repair materials (such as hot-mix asphalt or cold-mix asphalt). Hot-mix asphalt repair offers advantages such as fast repair speed and high initial strength, making it suitable for emergency repairs requiring rapid traffic reopening. Cold-mix asphalt repair, on the other hand, can be performed without heating equipment, is easy to operate, and is suitable for routine maintenance of smaller areas. However, because different types of repair materials have different requirements for construction conditions and environments, single-type repair equipment is often not universally applicable to different emergency scenarios, thus limiting its scope of application and repair effectiveness. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a hot-mix and cold-mix asphalt mixture repair mixing and paving device, which solves the problems of existing repair devices having a single repair type and being unable to adapt to different construction conditions and requirements.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A hot-mix and cold-mix asphalt mixture repair mixing and paving device is provided, including a binder silo and a storage hopper connected to the binder silo. The storage hopper and the binder silo are mounted on a moving mechanism. The moving mechanism includes a first fixed base. A scraper and a pressure roller are arranged below the first fixed base. The pressure roller is connected to a first lifting component.

[0008] The cementitious silo is equipped with a first stirring assembly, which is connected to a second lifting assembly. The cementitious silo is equipped with a first heater on the outside. The storage hopper is equipped with a second stirring assembly inside, and the storage hopper is equipped with an insulation layer on the outside, with a second heater inside. Both the cementitious silo and the storage hopper are mounted on a first fixed base. A control box is mounted on the first fixed base and is located on one side of the cementitious silo. The control box is equipped with several first control buttons.

[0009] The beneficial effects of adopting the above technical solution are as follows: the device integrates two repair methods, hot mixing and cold mixing, which can be switched according to the actual situation, greatly improving the efficiency of emergency repair, and making full use of repair materials, reducing waste and lowering repair costs. The system includes a first mixing component inside the binder silo to mix the binder, and the height of the first mixing component can be adjusted by a second lifting component. This not only adapts to different mixing needs but also ensures the uniformity of the binder mixing. The first heater located outside the binder silo prevents the binder from experiencing a decrease in road performance due to low temperature in winter or when temperatures drop. The second mixing component inside the storage hopper ensures the uniformity of the asphalt mixture. The insulation layer located outside the storage hopper maintains a stable internal temperature, preventing the mixture from cooling down during storage and transportation. The second heater heats the mixture during hot-mix repair to ensure it reaches a suitable paving temperature. During paving, the paving thickness of the repaired road surface can be controlled by adjusting the position and height of the scraper to meet different repair needs. The pressure roller can be raised and lowered by the first lifting component to compact the repaired road surface, improving repair efficiency and ensuring the smoothness and density of the repaired road surface.

[0010] Furthermore, a first feed inlet is provided on one side of the upper end of the cementing silo, and a first sealing cap is provided on the first feed inlet. A first discharge outlet is provided on one side of the cementing silo, and the first discharge outlet is connected to a second feed inlet through a connecting pipe. A one-way valve and a conveying pump are provided on the connecting pipe. The second feed inlet is located on one side of the storage tank, and a second discharge outlet is provided at the lower end of the storage tank. The second discharge outlet is connected to a sliding component. A third feed inlet is provided at the upper end of the storage tank, and a second sealing cap is provided on the third feed inlet.

[0011] The beneficial effects of adopting the above technical solution are as follows: The first inlet is used to input asphalt. The first sealing cap on the first inlet can effectively prevent the asphalt cold patching agent from evaporating due to environmental factors such as temperature and humidity changes during the preparation or storage of binder, ensuring the stability of the material performance. In addition, the first sealing cap can also prevent external impurities from entering the binder silo. The mixed asphalt is input into the storage tank through the first outlet and the second inlet. The one-way valve on the connecting pipeline can prevent backflow, ensuring the unidirectionality and stability of the flow. The delivery pump can ensure that the material can enter the storage tank evenly and stably, and undergo secondary mixing in the storage tank. The mixture after secondary mixing is released through the second outlet. The size of the second outlet can be flexibly adjusted by the sliding component, thereby controlling the discharge speed and paving thickness of the asphalt mixture.

[0012] Furthermore, the sliding assembly includes a first baffle plate and a second baffle plate, which are disposed on the second lead screw and the slide rail. The slide rail is disposed parallel to one side of the second lead screw. A third gear is disposed at one end of the second lead screw. The third gear is connected to a fourth gear through a second synchronous belt. The fourth gear is disposed on a second rotating shaft, which is disposed at the output end of a fourth drive motor.

[0013] The beneficial effects of adopting the above technical solution are as follows: the first baffle and the second baffle are used to block and control the flow of the mixture. When the fourth drive motor starts, its output end drives the second rotating shaft to rotate. The rotation of the second rotating shaft can drive the fourth gear and the third gear to rotate. When the third gear rotates, the second lead screw will rotate accordingly, thereby driving the first baffle and the second baffle to move linearly on the lead screw, realizing the opening and closing of the first baffle and the second baffle. The slide rail provides stable guidance and support for the first baffle and the second baffle, ensuring the stability and accuracy of the baffle during the movement.

[0014] Furthermore, the first lifting assembly includes a drive cylinder, the output end of which is connected to the lifting plate, and the lifting plate is connected to the pressure roller.

[0015] The beneficial effects of adopting the above technical solution are as follows: the height of the lifting plate and the pressure roller can be controlled by the drive motor, which makes it easier for construction personnel to adjust the height and pressure of the pressure roller according to the actual situation of the road surface being repaired, thereby ensuring the uniformity and compactness of the repair area and improving the repair quality.

[0016] Furthermore, the first stirring assembly includes a first stirring shaft and a first stirring blade disposed on the first stirring shaft. A first gear is disposed at one end of the first stirring shaft. The first gear is connected to a second gear via a first synchronous belt. The second gear is disposed on a first rotating shaft. The first rotating shaft is disposed at the output end of a first drive motor. The first drive motor is disposed on a second fixed base. The second fixed base is connected to a second lifting assembly.

[0017] The beneficial effects of adopting the above technical solution are as follows: When it is necessary to stir the mixture in the binder silo, the first drive motor is started first. The first drive motor drives the first rotating shaft to rotate, and the first rotating shaft drives the second gear to rotate. The second gear transmits power to the first gear through the first synchronous belt, which in turn drives the first stirring shaft to rotate. The rotation of the first stirring shaft drives the first stirring blade to stir the asphalt mixture in the binder silo, so as to achieve full mixing. During the stirring process, the speed and direction of the first drive motor can be adjusted as needed to change the intensity and direction of stirring. In addition, the height of the stirring assembly can be adjusted by the second lifting assembly to adapt to different stirring requirements.

[0018] Furthermore, the second lifting assembly includes a second drive motor and a first lead screw disposed at the output end of the second drive motor. Guide rods are disposed on both sides of the first lead screw. A second fixed base is connected to the first lead screw and the guide rods. A fourth fixed base is disposed at the lower end of the first lead screw and the guide rods. A third fixed base is disposed at the upper end of the first lead screw and the guide rods. A second drive motor is disposed above the third fixed base. A support rod is disposed below the third fixed base. The support rod is disposed on one side of the cementing hopper.

[0019] The beneficial effects of adopting the above technical solution are as follows: the third fixed base and the fourth fixed base are used to fix the second lead screw and the guide rod. When it is necessary to adjust the height of the first stirring shaft, the second drive motor can be started. The output end of the second drive motor drives the first lead screw to rotate. The rotation of the first lead screw drives the second fixed base to rise and fall linearly along the guide rod. The guide rod can ensure the stability during the lifting process. The height of the first stirring component can be adjusted through the second lifting component to adapt to different working requirements, which is conducive to improving construction efficiency and quality.

[0020] Furthermore, the second stirring assembly includes a second stirring shaft and a second stirring blade disposed on the second stirring shaft, with one end of the second stirring shaft connected to the output end of the third drive motor.

[0021] The beneficial effects of adopting the above technical solution are as follows: the second mixing component drives the second mixing shaft to rotate through the third drive motor, thereby driving the second mixing blade to mix, which can significantly improve the mixing efficiency, shorten the preparation time of asphalt mixture, and facilitate rapid response to the needs of emergency repair of asphalt pavement.

[0022] Furthermore, the bottom of the first fixed base is provided with casters, and the casters are equipped with brakes.

[0023] The beneficial effects of adopting the above technical solution are as follows: the casters at the bottom of the first fixed base allow the entire device to move easily, enabling it to quickly reach the site for repair work. It can adapt to the road repair needs of different locations, effectively improving the construction effect. The brake can lock the casters to prevent the device from moving or sliding accidentally, thereby ensuring the stability and safety of the construction process.

[0024] Furthermore, an infrared heating lamp is installed between the pressure roller and the scraper.

[0025] The beneficial effects of adopting the above technical solution are as follows: infrared heating lamps can heat the cold patch material after it is discharged, accelerate the volatilization of the diluent, help the cold patch material reach its initial strength as soon as possible, thereby shortening the curing time of the repaired road surface and improving the repair efficiency.

[0026] Furthermore, a handrail is provided on one side of the upper end of the first fixed base, the handrail is provided with a spiral anti-slip texture, and a second control button is provided on one side of the handrail.

[0027] The beneficial effects of adopting the above technical solution are as follows: the handrail makes it easier for construction workers to push the device, and it is convenient to move and adjust the position when performing emergency repairs on asphalt pavement, which improves construction efficiency. The spiral anti-slip texture increases the roughness of the handrail surface, making it easier for construction workers to grip. The second control button is connected to the control box, pressure roller and scraper through wires, which facilitates the adjustment of the position of the pressure roller, etc., and improves the convenience and flexibility of operation.

[0028] In summary, the beneficial effects of the hot-mix and cold-mix asphalt mixture repair mixing and paving device provided by this utility model are as follows:

[0029] (1) The device integrates two repair methods, hot mixing and cold mixing, which can be switched according to the actual situation. This avoids the tedious operation of frequently changing repair materials required by traditional repair devices, which not only simplifies the operation process and reduces the construction difficulty, but also helps to reduce equipment costs.

[0030] (2) By using the first mixing component and the second lifting component inside the binder silo, efficient mixing can be achieved, ensuring the uniformity and stability of the asphalt binder, thus providing a guarantee for subsequent repair work. In addition, the first heater outside the binder silo can help maintain the stability of the material, further ensuring the repair effect.

[0031] (3) The storage hopper is used to store and mix the asphalt mixture.

The insulation layer outside the storage hopper can further reduce heat loss and improve energy utilization efficiency. The sliding component at the second outlet of the storage hopper can be adjusted according to the size and shape of the repair area to adapt to the road repair needs of different widths and thicknesses, thereby improving the utilization rate of the device and the flexibility of the repair work.

[0032] (4) The scraper in the device can adjust the paving thickness of the repaired road surface.

The first drive motor 116 drives the first rotating shaft to rotate, and the first rotating shaft drives the second gear 115 to rotate. The second gear 115 transmits power to the first gear 113 through the first synchronous belt 114, which in turn drives the first stirring shaft 111 to rotate. The rotation of the first stirring shaft 111 drives the first stirring blade 112 to stir the asphalt mixture in the binder silo 1, so as to achieve thorough mixing. During the stirring process, the speed and direction of the first drive motor 116 can be adjusted as needed to change the intensity and direction of stirring.

The first baffle plate 241 and the second baffle plate 242 are used to block and control the flow of the mixture. When the fourth drive motor 248 starts, its output end drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the fourth gear 246 and the third gear 245 to rotate. When the third gear 245 rotates, the second lead screw 243 will rotate accordingly, thereby driving the first baffle plate 241 and the second baffle plate 242 to move linearly on the lead screw, realizing the opening and closing of the first baffle plate 241 and the second baffle plate 242. The slide rail 244 provides stable guidance and support for the first baffle plate 241 and the second baffle plate 242, ensuring the stability and accuracy of the baffle plate during movement. In addition, the inner wall corner of the storage tank 2 is rounded to avoid the problem of easy blockage of the second discharge port 27 and improve the repair efficiency of asphalt pavement.

[0047] When producing cold-mix asphalt, the required cold-mix asphalt is first fed into the first inlet 104 of the binder silo 1. In winter, when the temperature is low, the first heater 103 can be turned on to heat the asphalt to 20~30℃ to avoid the influence of temperature on the binder, so that the asphalt is in a semi-fluid state. Then, the diluent, admixture, thickener, etc. are gradually added. The first sealing cap 15 is tightened to prevent the diluent from evaporating. The first drive motor 116 is turned on to drive the first stirring blade 112 to stir the cold-mix asphalt and make it flow. Then, the aggregate is fed into the storage tank 2 through the third inlet 25. After moving the device to the repair section, press the brake 9 to align the second outlet 27 of the storage tank 2 with the repair area. Open the one-way valve 17 to allow the cold asphalt mixture to enter the storage tank 2. Turn on the second mixing component 21 inside the storage tank 2 to mix the cold asphalt mixture. After mixing, turn on the sliding component 24 at the second outlet 27 to fill the repair area with the mixed mixture. Adjust the repair thickness using the scraper 4. Then turn on the infrared heating lamp to heat the repaired road surface, accelerating the volatilization of the diluent in the mixture to achieve early strength as soon as possible. Finally, adjust the height of the lifting plate 14 to allow the pressure roller 5 to compact the repaired area. After compaction, adjust the lifting plate 14 to move the pressure roller 5 away from the road surface. The cold asphalt mixture repair process is now complete.

[0048] When producing hot-mix asphalt, the required asphalt is first fed into the first feed port 104 of the binder silo 1, the first heater 103 is turned on, the binder silo 1 is adjusted to the required temperature through the control box 6, the second mixing shaft 211 inside the binder silo 1 is turned on to stir the asphalt to make it flow. Then the aggregate is fed into the storage tank 2 through the collection and distribution feed port. After the second heater 22 of the storage tank 2 is turned on through the control box 6 to the appropriate paving temperature, the insulation layer 23 can be used for insulation. After the device moves to the repair section, press the brake 9 to align the second outlet 27 of the storage tank 2 with the repair area, open the one-way valve 17 to allow the hot-mix asphalt binder to enter the storage tank 2, and turn on the second mixing component 21 in the storage tank 2 to mix the mixture. After mixing, turn on the sliding component 24 to fill the repair area with the mixed mixture. Adjust the repair thickness by using the scraper 4, and then adjust the height of the lifting plate 14 to allow the pressure roller 5 to compact the repaired area. After compaction, adjust the lifting plate 14 to move the pressure roller 5 away from the road surface, and the hot-mix asphalt mixture repair process is completed.
