[0002] In asphalt pavement construction, the asphalt layer after paving needs to be cooled quickly to reach a suitable hardening state in order to facilitate subsequent traffic opening or further construction. Traditional cooling methods mainly rely on natural cooling, which is time-consuming and the cooling effect is affected by many factors such as weather and ambient temperature.

[0053] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0055] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0057] refer to Figure 1-11 An embodiment of the present invention shows a rapid cooling device for asphalt pavement paving, including two ground rails 1, two mobile carriers 2 and an air cooling mechanism 3, wherein the two ground rails 1 are respectively arranged on both sides of a road surface along the length direction of the road surface; the two mobile carriers 2 are movably arranged on the ground rails 1; the air cooling mechanism 3 includes a plurality of blowing units 31, and the plurality of blowing units 31 are sequentially spliced ​​along the width direction of the road surface, and the two blowing units 31 located at the two edge positions are respectively connected with connecting frames 32, and the two connecting frames 32 are respectively arranged on the two mobile carriers 2, thereby forming an air cooling structure across the road surface.

[0058] Among them, the blowing unit 31 can blow air downward to increase the air circulation speed on the road surface, thereby improving the cooling efficiency; multiple blowing units 31 span the road surface, and use the mobile carrier 2 to drive the movement along the length direction of the road surface, which can ensure that every position on the asphalt road surface can be cooled by blowing air, thereby improving the cooling uniformity. In addition, the number of splicing blowing units 31 can be determined according to the width of the road surface, so that the air cooling mechanism 3 has high adaptability to roads of different widths.

[0059] In some embodiments, Figure 4-6 As shown, the blowing unit 31 includes a mounting frame 311 and a fan module 312. The mounting frame 311 includes two parallel beams 3111, and a connecting rod 3112 is provided between the two beams 3111; the fan module 312 is arranged on the beam 3111. The beams 3111 are arranged along the width direction of the road surface, and the two beams 3111 are combined with the connecting rod 3112 to form a shape similar to "H", which has a simple structure and reduces weight. At the same time, it has good structural stability and can stably support and bear the fan module 312. The fan module 312 can be fixed to the beam 3111 by a bolt assembly, and the fan module 312 is located between the two beams 3111, which is convenient for blowing air downward. In addition, the two beams 3111 can be used for splicing, and the splicing structure will be described later.

[0060] In some embodiments, Figure 4-6As shown, the blowing unit 31 also includes a pressure-supporting mechanism 4, which is arranged below the mounting frame 311. The pressure-supporting mechanism 4 includes a first rod 41, a second rod 42 and an elastic member 46. The first rod 41 is vertically arranged, and the upper part of the first rod 41 is connected to the mounting frame 311; the second rod 42 is slidably sleeved on the lower part of the first rod 41, and the lower part of the second rod 42 is connected to a pressure plate 43; the elastic member 46 is used to drive the second rod 42 away from the first rod 41 so that the pressure plate 43 abuts against the road surface.

[0061] In other words, the elastic member 46 can realize elastic expansion and contraction between the second rod 42 and the first rod 41; the pressure plate 43 at the bottom of the second rod 42 can be supported on the road surface. On the one hand, the pressure support mechanism 4 can provide certain support to the mounting frame 311 and the fan module 312, reduce the load of the connecting frame 32, and for the case where the road surface is relatively wide, the pressure support mechanism 4 can promote the air cooling mechanism 3 to move more stably. On the other hand, the telescopic structure of the pressure support mechanism 4 can enable the pressure plate 43 to move smoothly when encountering uneven road surfaces, avoiding the air cooling mechanism 3 from getting stuck during movement; on the third hand, the elastic member 46 provides pressure to flatten the road surface on the pressure plate 43, and the pressure plate 43 can flatten the road surface when moving, which is conducive to improving the flatness of the road surface.

[0062] Specifically, the above scheme is as follows: Figure 6 As shown, the bottom of the pressing plate 43 is formed with a flat pressing support surface 431, and the pressing plate 43 is bent on both sides along the length direction of the road surface to form a first arc surface 432 and a second arc surface 433. The pressing support surface 431 is a flat surface that can form a certain area of ​​contact with the road surface. While forming a stable support for the mounting frame 311 and the fan module 312, it will not sink into the road surface due to excessive pressure, that is, it will not cause a bumpy structure on the road surface; in addition, when the pressing plate 43 reciprocates, it guides and contacts the road surface through the first arc surface 432 and the second arc surface 433. When there is an uneven convex structure on the road surface, the convex structure contacts the first arc surface 432 or the second arc surface 433, and the first arc surface 432 or the second arc surface 433 will exert a downward pressure on the convex structure, thereby promoting the flatness of the road surface and avoiding shoveling the convex structure.

[0063] In the above solution, more than one pressing plate 43 may be provided on the pressing mechanism 4, such as Figure 4-6As shown, multiple support rods 44 extend from the second rod 42, and the pressure plate 43 is arranged at the bottom of the support rod 44; the first rod 41 and the second rod 42 are axially corresponding to the central axis of the fan module 312, and multiple pressure plates 43 are distributed around the central axis of the fan module 312. In this way, multiple pressure plates 43 form multi-point support, further improving the support stability.

[0064] In some embodiments, the holding down mechanism 4 and the mounting frame 311 are detachably connected, so that it is not necessary to set up the holding down mechanism 4 on each blowing unit 31, and the holding down mechanism 4 can be easily replaced.

[0065] The above scheme is specific, such as Figure 5 and Figure 7 As shown, a locking assembly 45 is provided at the top of the first rod 41, and the locking assembly 45 includes a locking seat 451 with a C-shaped cross section and a locking bolt 452. A groove 4511 is provided on the side of the locking seat 451. The bottom of the locking seat 451 is fixedly connected to the top of the first rod 41. The connecting rod 3112 is arranged in the groove 4511. The locking bolt 452 is vertically arranged and threadedly connected to the locking seat 451. The end of the locking bolt 452 abuts against the bottom of the connecting rod 3112 to achieve the fixing of the connecting rod 3112 in the groove 4511. In this way, when it is necessary to disassemble the pressure support mechanism 4 on the mounting frame 311, the locking bolt 452 can be loosened to separate the end of the locking bolt 452 from the connecting rod 3112, and the connecting rod 3112 can be pulled out from the groove 4511 of the locking seat 451.

[0066] Specifically, in order to facilitate the stable extension and retraction between the first rod body and the second rod body, Figure 7 As shown, a slider 411 is fixedly provided at the bottom of the first rod 41, and the width of the slider 411 is greater than the diameter of the first rod 41; a sliding channel 421 is provided in the second rod 42, and an opening (not marked in the figure) is provided at the top of the second rod 42, the opening is connected to the sliding channel 421, and the width of the opening is less than the diameter of the sliding channel 421; the slider 411 is slidably set in the sliding channel 421; the elastic member 46 is a spring, and the spring is set in the sliding channel 421, one end of the spring abuts against the bottom of the slider 411, and the other end of the spring abuts against the inner wall of the sliding channel 421.

[0067] The slider 411 cannot pass through the opening, and the first rod 41 and the second rod 42 are not completely separated by the limitation of the slider 411. The second rod 42 can stably extend and retract vertically by the cooperation between the sliding channel 421 and the slider 411.

[0068] In some embodiments, in order to facilitate the splicing between multiple blowing units 31, as shown in FIG. Figure 3 and Figure 8 As shown, the crossbeam 3111 is a pipe fitting, and first connecting holes 3113 radially passing through are provided at both ends of the crossbeam 3111; a splicing piece 33 is provided between two adjacent blowing units 31, and the splicing piece 33 includes two plug-in parts 331, and the plug-in parts 331 are used to insert the ends of the crossbeam 3111, and a second connecting hole 3311 corresponding to the first connecting hole 3113 is opened on the plug-in part 331, and a bolt assembly (not shown) is provided between the first connecting hole 3113 and the second connecting hole 3311 to realize the fixed connection between the splicing piece 33 and the crossbeam 3111; in this embodiment, the splicing structure is simple, the manufacturing cost is low, and stable splicing of the crossbeams 3111 on the two blowing units 31 can be realized.

[0069] In addition, in order to facilitate the connection between the blowing unit 31 and the connecting frame 32, as shown in FIG. Figure 3 and Fig. 9 As shown, the connecting frame 32 includes an insertion rod 321 for inserting into the end of the cross beam 3111, and the insertion rod 321 is provided with a plurality of third connection holes 3211, and the plurality of third connection holes 3211 are arranged at intervals along the length direction of the insertion rod 321, and the first connection hole 3113 on the cross beam 3111 corresponds to one of the third connection holes 3211, and a bolt assembly is provided between the first connection hole 3113 and the third connection hole 3211 to achieve a fixed connection between the cross beam 3111 and the connecting frame 32. Among them, by selecting the third connection hole 3211 at a suitable position to connect with the first connection hole 3113, the depth of the insertion of the insertion rod 321 into the cross beam 3111 can be adjusted, that is, the distance between the connecting frame 32 and the blowing unit 31 can be adjusted, so as to further adapt to road surfaces of different widths.

[0070] In some embodiments, Fig.10 As shown, the mobile carrier 2 includes a walking mechanism 21, a platform 22 and a scissor-type bracket 23. The walking mechanism 21 is movably set on the ground rail 1, the platform 22 is set above the walking mechanism 21, and the connecting frame 32 is detachably set on the platform 22; the scissor-type bracket 23 is set between the walking mechanism 21 and the platform 22 to realize the lifting and lowering of the platform 22.

[0071] In this embodiment, the walking mechanism 21 can be driven by a motor to achieve walking, and the forward and reverse rotation of the motor can be controlled by PLC according to the required moving length, so as to achieve reciprocating movement of the walking mechanism 21 within a certain length; wherein, the walking mechanism 21 can refer to the existing technology, such as the trolley structure, which will not be described here; the scissor-type bracket 23 is driven by a hydraulic cylinder to achieve the lifting and lowering of the platform 22.

[0072] In the above scheme, if Fig.11 As shown, the height of the platform 22 can be adjusted to adjust the distance between the fan module 312 and the road surface, thereby adjusting the wind force; wherein, relative to the wind force level adjustment of the fan module 312 itself (the wind force levels generally include low, medium, and high levels), the method of adjusting the wind force by adjusting the distance in this embodiment can achieve stepless adjustment, rather than changing from one wind force level to another in a step-by-step manner, and the wind force adjustment is more detailed. Of course, the height adjustment of the platform 22 can be adjusted in conjunction with the wind force level of the fan module 312 itself, making it more applicable; at the same time, in the process of adjusting the height of the platform 22, the pressure of the pressure plate 43 on the road surface will be adjusted. When the height of the platform 22 is lower, the elastic force provided by the elastic member 46 is greater, and the pressure of the pressure plate 43 on the road surface is also greater;

[0073] Specifically, when strong wind force and low pressure are needed, the height of the carrier 22 can be adjusted higher and a high-level wind speed gear on the fan module 312 can be selected; when strong wind force and high pressure are needed, the height of the carrier 22 can be lowered; and so on. Users can flexibly match according to actual needs.

[0074] In addition, the present invention also provides a rapid cooling process for asphalt pavement paving, comprising the following steps:

[0075] Divide the construction section into multiple length segments;

[0076] When completing asphalt paving of one length section and starting asphalt paving of the next length section;

[0077] The above-mentioned asphalt pavement paving rapid cooling device is used to blow air to cool the length section that has previously completed asphalt paving. During the blowing and cooling process, the mobile carrier 2 moves back and forth on the ground rail 1, allowing the air cooling mechanism 3 to blow air back and forth on the length section.

[0078] In summary, the present application provides a rapid cooling process and device for asphalt pavement paving, which has at least the following beneficial effects compared with the prior art:

[0079] 1. Significantly improve cooling efficiency and cooling uniformity: By adopting an air-cooling structure that spans the road surface and using multiple blowing units 31 to work simultaneously, the temperature of the asphalt layer can be quickly reduced, significantly shortening the cooling time. The mobile carrier 2 can reciprocate on the ground rail 1, so that the air-cooling mechanism 3 can evenly and efficiently cover the entire paving surface, further improving the cooling efficiency. The blowing units 31 are spliced ​​in sequence along the width of the road surface, ensuring the uniform distribution of cooling wind force and avoiding local overheating or overcooling.

[0080] 2. Flexible adaptation to different road widths: The air cooling mechanism 3 is composed of multiple blowing units 31, so the length of the air cooling mechanism 3 can be flexibly designed according to the actual width of the road. This design enables the device to be applicable to construction sections of different widths, without the need to replace equipment due to changes in road width, thereby enhancing the versatility and adaptability of the device.

[0081] 3. Reduce the impact on traffic: The rapid cooling device can greatly improve the cooling efficiency. On this basis, the rapid cooling process uses the device to achieve simultaneous cooling and paving on different lengths of the construction section. That is, when asphalt is paved on a length section, the previous paved and initially solidified length section can be quickly cooled, thereby greatly improving the overall construction efficiency and significantly shortening the closure time of the construction section.

[0082] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
