Description

Technical Field

[0001] This invention relates to the field of road construction technology, and more specifically to a GTM asphalt road construction device and its construction method. Background Technology

[0002] With the increase in traffic volume and urban traffic congestion, it is necessary to build more municipal roads to alleviate traffic tension. Asphalt is usually used to pave the roads. Before construction, the road is cleaned, and then the mixed asphalt is laid on the road surface sprayed with tack coat using a paver. Finally, a road roller is used to compact the road surface to complete the paving.

[0003] However, existing asphalt pavements usually need to wait until the pavement temperature drops below 50°C before they can be used normally after paving. Due to the long cooling time, small vehicles can usually only travel after three hours, while large vehicles need 24 hours. This causes great inconvenience to vehicles that need to pass through, thus affecting traffic. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a GTM asphalt road construction device. This device sprays water onto the compacted road surface, which increases the cooling speed of the asphalt road surface and facilitates the road to be put into normal use as soon as possible.

[0005] The technical solution of the present invention is as follows:

[0009] As a preferred embodiment, the air blowing assembly includes a first air cylinder fixedly mounted on the mounting plate, a first air inlet pipe fixedly connected to one end of the first air cylinder, a second air inlet pipe fixedly connected to the other end of the first air cylinder, a first air outlet pipe fixedly mounted at one end of the first air cylinder, a second air outlet pipe fixedly mounted at the other end of the first air cylinder, first air chambers fixedly mounted on both sides of the bottom of the mounting plate, a plurality of air nozzles fixedly mounted at the bottom of the first air chambers, a second piston slidably mounted inside the first air cylinder, and a second fixing rod fixedly mounted on the other side of the nut. The second piston rod is fixedly mounted on the second fixing rod, and the second piston is fixedly mounted on the second piston rod. The first air outlet pipe and the second air outlet pipe are respectively connected to the two first air chambers. A third one-way valve is provided on both the first air inlet pipe and the second air inlet pipe, and a fourth one-way valve is provided on both the first air outlet pipe and the second air outlet pipe.

[0010] As a preferred embodiment, the cooling assembly includes a cooling box fixedly disposed at the end of the mounting plate, an ice inlet fixedly disposed at the top of the cooling box, and an ice outlet fixedly disposed at the bottom of the cooling box, wherein the bottom of the cooling box is configured as an arc-shaped structure.

[0011] As a preferred embodiment, the mounting plate is further provided with an air intake assembly, which includes a second air cylinder fixedly mounted on the mounting plate, a second air chamber fixedly mounted at the end of the cooling box, a plurality of heat-absorbing covers fixedly mounted at the bottom of the second air chamber, a third air inlet pipe fixedly connected between one end of the second air cylinder and the second air chamber, a third air outlet pipe fixedly connected to one end of the second air cylinder, a third piston slidably mounted inside the second air cylinder, and a third piston rod fixedly mounted on the third piston. A fifth one-way valve is provided on the third air inlet pipe, and a sixth one-way valve is provided on the third air outlet pipe.

[0012] As a preferred embodiment, a connecting rod is fixedly provided at the end of the second piston, one end of the connecting rod extends out of the first air cylinder, and a connecting plate is fixedly provided between the end of the connecting rod and the end of the third piston rod.

[0013] Preferably, the position of the nozzle corresponds to the position of the air blowing nozzle.

[0014] As another preferred embodiment, the air nozzle is inclined and the air nozzles located on both sides of the bottom of the mounting plate are symmetrically distributed.

[0015] Another objective of this invention is to provide a GTM asphalt road construction method, the technical solution of which is as follows:

[0016] S1. Clean the impurities in the roadbed and repair and level the potholes in the roadbed;

[0017] S2. Add the mixed asphalt material to the paver and use the paver to lay the asphalt material on the road surface sprayed with tack coat. After the road surface is laid, use the road roller to roll the asphalt road surface back and forth alternately. The road surface temperature after rolling is 0℃~00℃.

[0018] S3. Spray water onto the road surface alternately through the nozzles on both sides of the bottom of the mounting plate, while blowing air into the sprayed water to turn it into a mist before spraying it onto the road surface to cool it down. Once the road surface has cooled down to 50°C, clear the obstructions and open the road to traffic.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention includes a drive assembly and a water spraying assembly. When the asphalt pavement is repeatedly rolled, the drive wheel rotates, driving the shaft and the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, driving the fixed shaft and the lead screw to rotate. This causes the nut to drive the first piston rod and the first piston to reciprocate, compressing the water in the water tank to the nozzle and spraying it onto the pavement. By spraying water, the heat from the asphalt pavement is carried away, cooling the pavement and reducing the cooling time, thus avoiding prolonged disruption to traffic.

[0021] This invention is equipped with an air blowing component. While the nozzle is spraying water, the nut drives the second piston rod and the second piston to reciprocate, compressing the air in the first air cylinder to the air blowing nozzle and blowing it towards the nozzle. This makes the water sprayed from the nozzle appear as a water mist, which can be more evenly sprayed onto the asphalt road surface, accelerate the water evaporation rate, and achieve a better cooling effect.

[0022] The invention also includes a cooling component that adds ice to the cooling box to lower the temperature at the bottom of the cooling box. The sprayed water is automatically cooled as it passes over the bottom of the cooling box. In addition, the cooling box also prevents the water mist from spreading randomly, allowing the water mist to fall more accurately onto the asphalt road surface, further improving the cooling speed.

[0023] In summary, this invention has advantages such as high cooling efficiency and minimal impact on traffic, making it suitable for the field of road construction technology. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 7 As shown, a GTM asphalt road construction device includes a roller body 1, a drive wheel 2 rotatably mounted on the roller body 1, a drive assembly 3 inside the roller body 1, a mounting plate 4 at the end of the roller body 1, a water spray assembly 5 mounted on the mounting plate 4, the water spray assembly 5 including a first piston rod 51, an air blowing assembly 6 mounted on the mounting plate 4 including a second piston rod 611, and a cooling assembly 7 at the end of the mounting plate 4. The drive assembly 3 is used to drive the first piston rod 51 and the second piston rod 611 to reciprocate under the action of the drive wheel 2. The water spray assembly 5 is used to spray water onto the compacted road surface, the air blowing assembly 6 is used to blow air onto the sprayed water, and the cooling assembly 7 is used to cool the sprayed water. The rotation of the drive wheel 2 on the roller body 1 is prior art, and the driving principle will not be described in detail here.

[0037] like Figure 2 and Figure 5As shown, the drive assembly 3 includes a rotating shaft 31 fixedly mounted in the middle of the drive wheel 2, a first bevel gear 32 fixedly mounted on the rotating shaft 31, a fixed seat 33 fixedly mounted inside the roller body 1, a connecting shaft 34 rotatably mounted on the fixed seat 33, a lead screw 35 fixedly mounted at the end of the connecting shaft 34, a nut 36 threadedly connected to the lead screw 35, a slider 37 fixedly mounted on the top of the nut 36, a slide block 38 fixedly mounted inside the roller body 1, and a second bevel gear 39 fixedly mounted on the fixed shaft 34. The first bevel gear 32 meshes with the second bevel gear 39, and the slider 37 slides inside the slide block 38.

[0038] like Figure 2 As shown, the water spray assembly 5 includes a water tank 52 fixedly mounted on the mounting plate 4, a water reservoir 53 fixedly mounted on the mounting plate 4, a first water inlet pipe 54 fixedly connected to one end of the water tank 52 and the water reservoir 53, a second water inlet pipe 55 fixedly connected to the other end of the water tank 52 and the water reservoir 53, a first water outlet pipe 56 fixedly mounted to one end of the water reservoir 53, a second water outlet pipe 57 fixedly mounted to the other end of the water reservoir 53, water cavities 58 fixedly mounted on both sides of the bottom of the mounting plate 4, a plurality of nozzles 59 fixedly mounted at the bottom of the water cavities 58, a first piston 511 slidably mounted inside the water reservoir 53, and a first fixing rod 512 fixedly mounted on one side of the nut 36. The first piston rod 51 is fixedly mounted on the first fixing rod 512, and the first piston 511 is fixedly mounted on the first piston rod 51. The first water outlet pipe 56 and the second water outlet pipe 57 are respectively connected to the two water cavities 58. A first single nozzle is provided on both the first water inlet pipe 54 and the second water inlet pipe 55. The system is equipped with a second one-way valve on both the first water outlet pipe 56 and the second water outlet pipe 57. The first one-way valve controls the water in the water tank 52 to flow from the first water inlet pipe 54 and the second water inlet pipe 55 into the water reservoir 53, preventing it from flowing back into the water tank 52. The second one-way valve controls the water in the water reservoir 53 to flow from the first water outlet pipe 56 and the second water outlet pipe 57 into the nozzle 59, preventing it from flowing back into the water reservoir 53. During use, when the asphalt pavement is repeatedly rolled, the drive wheel 2 rotates, driving the shaft 31 and the first bevel gear 32 to rotate. The first bevel gear 32 meshes with the second bevel gear 39, driving the connecting shaft 34 and the lead screw 35 to rotate. This causes the nut 36 to drive the first piston rod 51 and the first piston 511 to reciprocate, compressing the water in the water reservoir 53 to the nozzle 59 and spraying it onto the road surface. By spraying water, the heat from the asphalt pavement is carried away, cooling the road surface, reducing the road surface cooling time, and avoiding long-term impact on traffic.

[0039] like Figure 2As shown, the air blowing assembly 6 includes a first air cylinder 61 fixedly mounted on the mounting plate 4, a first air inlet pipe 62 fixedly connected to one end of the first air cylinder 61, a second air inlet pipe 63 fixedly connected to the other end of the first air cylinder 61, a first air outlet pipe 64 fixedly mounted at one end of the first air cylinder 61, a second air outlet pipe 65 fixedly mounted at the other end of the first air cylinder 61, first air chambers 66 fixedly mounted on both sides of the bottom of the mounting plate 4, a plurality of air nozzles 67 fixedly mounted at the bottom of the first air chambers 66, a second piston 68 slidably mounted inside the first air cylinder 61, and a second fixing rod 69 fixedly mounted on the other side of the nut 36. The second piston rod 611 is fixedly mounted on the second fixing rod 69, and the second piston 68 is fixedly mounted on the second piston rod 611. The first air outlet pipe 64 and the second air outlet pipe 65 are respectively connected to the two first air chambers 66. A third one-way valve is installed on both the first air outlet pipe 62 and the second air inlet pipe 63, and a fourth one-way valve is installed on both the first air outlet pipe 64 and the second air outlet pipe 65. The third one-way valve is used to control the outside air to enter the first air cylinder 61 from the first air outlet pipe 64 and the second air inlet pipe 63, and the air in the first air cylinder 61 cannot flow back to the outside. The fourth one-way valve is used to control the air in the first air cylinder 61 to enter the air nozzle 67 from the first air outlet pipe 64 and the second air outlet pipe 65, and the air cannot flow back to the first air cylinder 61. When in use, while the nozzle 59 sprays water, the nut 36 drives the second piston rod 611 and the second piston 68 to reciprocate, compressing the air in the first air cylinder 61 to the air nozzle 67 and then blowing air onto the nozzle 59, so that the water sprayed from the nozzle 59 is in the form of water mist, which can be more evenly sprayed onto the asphalt road surface, accelerate the water evaporation rate, and have a better cooling effect.

[0040] like Figure 3 As shown, the cooling component 7 includes a cooling box 71 fixedly installed at the end of the mounting plate 4, an ice inlet 72 fixedly installed at the top of the cooling box 71, and an ice outlet 73 fixedly installed at the bottom of the cooling box 71. The bottom of the cooling box 71 is designed with an arc-shaped structure. When in use, ice is added into the cooling box 71 to lower the temperature at the bottom of the cooling box 71. The sprayed water is automatically cooled when it passes through the bottom of the cooling box 71. In addition, the cooling box 71 also prevents water mist from spreading randomly, allowing the water mist to fall more accurately onto the asphalt road surface, further improving the cooling speed.

[0041] like Figure 2As shown, the mounting plate 4 is also equipped with an air intake assembly 8. The air intake assembly 8 includes a second air cylinder 81 fixedly mounted on the mounting plate 4, a second air chamber 82 fixedly mounted at the end of the cooling box 71, several heat absorption covers 83 fixedly mounted at the bottom of the second air chamber 82, a third air inlet pipe 84 fixedly connected between one end of the second air cylinder 81 and the second air chamber 82, a third air outlet pipe 85 fixedly connected to one end of the second air cylinder 81, a third piston 86 slidably mounted inside the second air cylinder 81, and a third piston rod 87 fixedly mounted on the third piston 86. A fifth one-way valve is provided on the third air inlet pipe 84, and a fifth one-way valve is provided on the third air outlet pipe 85. There is a sixth one-way valve. The fifth one-way valve is used to control the hot air from the road surface to enter the second air cylinder 81 through the heat absorption hood 83 and the third air inlet pipe 84, and prevents it from flowing back to the heat absorption hood 83. The sixth one-way valve is used to control the air in the second air cylinder 81 to enter the third air outlet pipe 85, and prevents it from flowing back to the second air cylinder 81. In use, when the third piston 86 and the third piston rod 87 move towards the cooling box 71 along with the second piston rod 611, the heat absorption hood 83 draws the hot air from the road surface into the second air cylinder 81 through the third air inlet pipe 84. This allows the heat absorption hood 83 to draw away the hot air from the road surface while also drawing away some water mist, further improving the cooling efficiency.

[0042] like Figure 2 As shown, a connecting rod 9 is fixedly provided at the end of the second piston 68. One end of the connecting rod 9 passes through the first air cylinder 61. A connecting plate 91 is fixedly provided between the end of the connecting rod 9 and the end of the third piston rod 87, so that the third piston rod 87 and the third piston 86 can reciprocate following the connecting rod 9.

[0043] like Figure 4 As shown, the position of the nozzle 59 corresponds to the position of the air nozzle 67, so that the air nozzle 67 blows the water sprayed from the nozzle 59 into a water mist, which can spray the road surface more evenly and cover a larger area.

[0044] like Figure 6 As shown, the air nozzle 67 is set at an angle, and the air nozzles 67 located on both sides of the bottom of the mounting plate 4 are symmetrically distributed. By setting the air nozzle 67 at an angle, the blown air can come into more full contact with the water sprayed from the nozzle 59, resulting in a better blowing effect.

[0045] Example 2

[0046] like Figure 7 As shown, a GTM asphalt road construction method includes the following steps:

[0047] S1. Clean the impurities in the roadbed and repair and level the potholes in the roadbed;

[0048] S2. Add the mixed asphalt material to the paver and use the paver to lay the asphalt material on the road surface sprayed with tack coat. After the road surface is laid, use the roller body 1 to roll the asphalt road surface back and forth alternately. The road surface temperature after rolling is 80℃~100℃.

[0049] S3. Spray water onto the road surface alternately through the nozzles 59 on both sides of the bottom of the mounting plate 4, while blowing air into the sprayed water through the air nozzles 67, turning the sprayed water into a water mist and spraying it onto the road surface to cool it down. After the road surface cools down to 50°C, clear the road obstructions and open the road to traffic.

[0050] Work process

[0051] During use, when the asphalt pavement is repeatedly compacted, the drive wheel 2 rotates, driving the connecting shaft 34 and the lead screw 35 to rotate. This causes the nut 36 to drive the first piston rod 51 and the first piston 511 to reciprocate, compressing the water in the water tank 53 to the nozzle 59 and spraying it onto the road surface. The water spraying removes the heat from the asphalt pavement, cooling the pavement. At the same time, the nut 36 drives the second piston rod 611 and the second piston 68 to reciprocate, compressing the air in the first air cylinder 61 to the air nozzle 67 and blowing it onto the nozzle 59. This makes the water sprayed from the nozzle 59 appear as a water mist, which can be more evenly sprayed onto the asphalt pavement. When the third piston 86 and the third piston rod 87 move towards the cooling box 71 along with the second piston rod 611, the heat absorption hood 83 draws the hot air from the road surface into the second air cylinder 81 through the third air inlet pipe 84. This allows the heat absorption hood 83 to remove the hot air from the road surface and also remove some of the water mist, further improving the cooling efficiency.
