Description

Technical Field

[0001] The present invention relates to the technical field of smart highway pavement repair, and in particular to a smart highway pavement repair device. Background Art

[0002] Smart highway pavements differ significantly from conventional highway pavements in terms of material technology, functional design, and management and maintenance. The core of these approaches lies in achieving efficient coordination and safety optimization throughout the road's entire lifecycle through digital and intelligent technologies. Smart highway pavements often utilize novel materials with specialized properties, such as composite phase-change asphalt mixtures. These materials utilize heat absorption and release properties to regulate pavement temperature, reducing high-temperature rutting and low-temperature cracking. Damaged pavements made of these materials require repair using composite phase-change asphalt mixtures.

[0003] Composite phase-change asphalt mixtures are made by mixing phase-change materials (PCMs) and asphalt. The melting point of the PCM (e.g., approximately 50-70°C for paraffin wax) must match the asphalt mixing temperature (typically 160-180°C). The paving temperature of the PCM must be 10-15°C higher than the PCM's melting point (typically ≥140°C) to avoid a sudden increase in the PCM's viscosity due to low temperatures (e.g., PCMs such as paraffin wax tend to solidify at temperatures below 40°C, increasing paving resistance). The paving speed should be controlled at 2-3 m / min to ensure uniform distribution. Highway repair construction, often associated with low traffic, is often carried out at night, when the ambient temperature is generally lower. During low-temperature construction (<10°C), the solidification of the PCM significantly impacts the compaction of the PCM during paving, potentially leading to insufficient compaction of the PCM due to the increased viscosity of the PCM. Therefore, some existing pavement repair equipment is equipped with a flame head for heating. When using composite phase-change asphalt mixture to repair damaged areas of smart highway pavement, the flame head will be used to preheat the underlying layer of the damaged area.

[0004] However, when treating the damaged pavement subsoil, conventional repair technology is limited by the range of the flame head. This results in uneven heating of the subsoil due to the limited range of the flame head, leading to temperature variations across the subsoil during the repair process. For example, when using conventional heating equipment for repair, the heat transfer process fails to fully reach every corner of the subsoil. This results in overheating in some areas, prematurely altering the properties of the composite phase-change asphalt mixture and weakening its bond to the pavement. In areas where the temperature is too low, the composite phase-change asphalt mixture loses its fluidity over the next year, making it difficult to compact the filler and preventing it from forming a dense structure. This ultimately leads to uneven filler density in the repaired pavement. Over time, cracks, potholes, and other damage will first appear in areas with weaker density, reducing the durability of the repaired pavement. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and provide an intelligent highway pavement repair equipment that can ensure that the temperature field of the entire underlying layer at the damaged location is uniform, so that the density of the repair layer filler is uniform after the damaged pavement is repaired.

[0020] The following is combined with Figure 1-Figure 7 , the specific embodiments of the present invention are described in detail, but it should be understood that the scope of protection of the present invention is not limited by the specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figure 1-Figure 7As shown, the present invention provides an intelligent highway pavement repair equipment, including a vehicle body 1, a feeding mechanism 101, a compacting mechanism 102, a plurality of flame heads 104 and a fuel supply device, wherein the feeding mechanism 101 is arranged at the front end of the vehicle body 1, the compacting mechanism 102 is arranged at the rear end of the vehicle body 1, the plurality of flame heads 104 are arranged between the feeding mechanism 101 and the compacting mechanism 102, and the fuel supply device supplies fuel to the plurality of flame heads 104, and also includes: a reciprocating swing mechanism 105, a reciprocating push-pull mechanism and a plurality of slip rings 301, the reciprocating swing mechanism 105 includes a rotating shaft 201, the rotating shaft 201 is arranged along the width direction of the vehicle body 1 and is rotatably connected to the vehicle body 1, the rotating shaft 201 is connected to a reciprocating rotating mechanism, the reciprocating rotating mechanism is used to drive the rotating shaft 201 to reciprocate within a predetermined angle, and the rotating shaft 201 is provided with a limiting sliding groove 303 along the axial direction of the rotating shaft 201; the plurality of slip rings 301 are slidably connected Connected to the rotating shaft 201, each flame head 104 is arranged on a slip ring 301, and each slip ring 301 is provided with a limit slider 302, and each limit slider 302 is slidably connected to the limit slider 303 along the length direction of the limit slider 303, and the limit slider 302 and the limit slider 303 are used to prevent the slip ring 301 from rotating relative to the rotating shaft 201; a reciprocating push-pull mechanism is connected to each slip ring 301, and the reciprocating push-pull mechanism is used to drive multiple slip rings 301 to reciprocate along the axial direction of the rotating shaft 201, thereby driving multiple flame heads 104 to reciprocate along the width direction of the vehicle body 1; a regulating valve 107 is provided between each flame head 104 and the fuel supply part 103, and the regulating valve 107 controls the fire power sprayed by the flame head 104 according to the angle between the flame head 104 and the vertical direction, so that the fire power sprayed by the flame head 104 is proportional to the angle between the flame head 104 and the vertical direction.

[0022] The working principle of the above embodiment is briefly described below: When the device is in use, the vehicle body 1 is driven to the damaged part of the road surface of the smart highway. Before the unloading mechanism 101 lays the composite phase-change asphalt mixture, the ground at the damaged part of the road surface is heated by spraying fire by controlling multiple flame heads 104. In this process, the reciprocating rotation mechanism is controlled to drive the rotating shaft 201 to reciprocate within a predetermined angle. The rotating shaft 201 drives the slip ring 301 to reciprocate along the axial direction of the rotating shaft 201 through the limiting slider 302 and the limiting slide groove 303. The slip ring 301 drives the flame heads 104 arranged thereon to rotate around the axis of the rotating shaft 201. Since the rotating shaft 201 is arranged along the width direction of the vehicle body 1, and multiple flame heads 104 are arranged on the rotating shaft 201 along the axial direction of the rotating shaft 201, when the rotating shaft 201 rotates, multiple flame heads 104 are used to perform swing scanning heating on the damaged road surface, that is, the lower supporting layer, along the length direction of the vehicle body 1. Compared with the push-pull scanning heating, the swing scanning heating of the flame heads 104 along the length direction of the vehicle body 1 can heat the lower supporting layer directly below the unloading mechanism 101 and the compacting mechanism 102 in real time, thereby During the process of material discharging and compaction by the compaction mechanism 102, the real-time temperature of the lower supporting layer directly below the material discharging mechanism 101 and the compaction mechanism 102 is maintained, so that the real-time temperature of the two places is always at the optimal ambient temperature for the construction of the composite phase change asphalt mixture. At the same time, when the flame head 104 is in a vertical state, the flame head 104 and the ejected flame have the shortest stroke when contacting the lower supporting layer, and the lower supporting layer directly below the flame head 104 is subjected to the greatest heat. As the flame head 104 swings, the angle between the flame head 104 and the vertical direction increases, and the flame head 104 is in a vertical state. When the flame ejected from 04 contacts the underlying layer, its stroke increases. At this time, the heat exerted on the underlying layers on both sides directly below the flame head 104 decreases. The regulating valve 107 is used to adjust the speed at which the fuel supply unit 103 supplies fuel to the flame head 104, thereby adjusting the firepower of the flame head 104 to achieve the minimum firepower when the flame head 104 is in the vertical direction. When the flame head 104 swings, as the swing amplitude of the flame head 104 increases, the firepower ejected from the flame head 104 also increases, thereby ensuring that the heat exerted on the underlying layer is more uniform. The reciprocating push-pull mechanism drives multiple sliders to reciprocate axially along the rotating shaft 201, thereby driving multiple flame heads 104 to reciprocate along the width of the vehicle body 1, thereby scanning and heating the lower supporting layer along the width direction of the vehicle body 1. Under the action of the reciprocating swing mechanism 105 and the reciprocating push-pull mechanism, the lower supporting layer can be heated more evenly, ensuring that the temperature field of the entire lower supporting layer at the damaged location is uniform, so that when repairing the road surface, the composite phase change asphalt mixture on the entire lower supporting layer is at the optimal ambient temperature, so that when the composite phase change asphalt mixture is subsequently compacted, the density of the repair layer filler after the damaged road surface is repaired is uniform, thereby ensuring the durability of the repaired road surface.

[0023] The smart highway pavement repair equipment of the present invention can ensure that the temperature field of the entire underlying layer at the damaged location is uniform when using the composite phase-change asphalt mixture to repair the damaged smart highway, so that the composite phase-change asphalt mixture on the entire underlying layer is at a suitable ambient temperature when repairing the pavement, so that the density of the repair layer filler is uniform after the damaged pavement is repaired, thereby ensuring the durability of the repaired pavement.

[0024] On the basis of the above embodiment, in order to synchronously drive multiple flame heads 104 to cyclically heat the underlying layer at the damaged part, the heating uniformity of the composite phase change asphalt mixture is achieved.

[0025] like Figure 1-Figure 7 As shown, the reciprocating push-pull mechanism includes a transmission shaft 401 and multiple cams 402. The transmission shaft 401 is arranged parallel to the rotating shaft 201 and is rotatably connected to the vehicle body 1. The transmission shaft 401 is connected to the power device 202. The multiple cams 402 are arranged on the transmission shaft 401 along the axial direction of the transmission shaft 401. Each cam 402 is provided with a cam groove 403. A driving slider 404 is slidably connected in the cam groove 403. The driving slider 404 is connected to a ring sleeve 405. The ring sleeve 405 is rotatably connected to the slip ring 301. When the cam 402 on the driving transmission shaft 401 rotates, the cam 402 drives the slip ring 301 to reciprocate along the axial direction of the transmission shaft 401 through the cam groove 403, the driving slider 404 and the ring sleeve 405.

[0026] The power device 202 drives the transmission shaft 401 to rotate, thereby driving the multiple cams 402 to rotate. Each cam 402 drives the driving slider 404 to reciprocate along the axial direction of the transmission shaft 401 through the cam groove 403 thereon, thereby driving the ring 405 to reciprocate along the axial direction of the transmission shaft 401. Since the transmission shaft 401 is arranged parallel to the rotating shaft 201, the ring 405 also reciprocates along the axial direction of the rotating shaft 201. The ring 405 drives the slip ring 301 and the flame head 104 to reciprocate along the axial direction of the rotating shaft 201. That is, the vehicle body 1 reciprocates in the width direction. Driven by multiple cams 402, multiple flame heads 104 can be synchronously driven to heat the lower supporting layer of the damaged part in a cyclical reciprocating manner along the width direction of the vehicle body 1, thereby improving the heating uniformity of the composite phase change asphalt mixture. Since the slip ring 301 is rotatably connected to the ring sleeve 405, when the rotating shaft 201 rotates back and forth to drive the flame head 104 to swing along the length direction of the vehicle body 1, it can ensure that the ring sleeve 405 can normally drive the flame head 104 to reciprocate in the width direction of the vehicle body 1.

[0027] As a preferred solution, Figure 3-Figure 7As shown, the regulating valve 107 is provided on the flame head 104, the control part of the regulating valve 107 is connected to the gear 801, and the lower side of the ring sleeve 405 is provided with a gear block 802, and the gear block 802 is gear-engaged with the gear 801. When the flame head 104 rotates relative to the ring sleeve 405, the gear 801 rolls on the gear block 802 to adjust the opening of the regulating valve 107, thereby adjusting the firepower of the flame head 104. By providing the gear 801 and the tooth block 802, when the rotating shaft 201 drives the slip ring 301 to rotate through the limiting slide groove 303, the slip ring 301 drives the flame head 104 connected thereto to rotate around the tooth block 802 on the ring sleeve 405, and the regulating valve 107 on the flame head 104 rotates around the tooth block 802. The gear 801 on the regulating valve 107 rolls on the tooth block 802, thereby automatically adjusting the opening of the regulating valve 107 to accurately adjust the firepower of the flame head 104, ensuring that the firepower ejected by the flame head 104 increases synchronously with the angle between the flame head 104 and the vertical direction, further ensuring the uniformity of heating of the lower bearing layer.

[0028] As a preferred solution, Figure 3 and Figure 4As shown, the reciprocating rotation mechanism includes a full gear 601, a half gear 602 and a coil spring 603, the half gear 602 is connected to the rotating shaft 201, the full gear 601 is gear-engaged with the half gear 602, the full gear 601 is arranged on the transmission shaft 401, and the coil spring 603 is arranged at the connection between the rotating shaft 201 and the vehicle body 1, and the coil spring 603 is used to apply an elastic force around the rotating shaft 201 to the rotating shaft 201. When the power device 202 drives the rotating shaft 201 to rotate through the full gear 601 and the half gear 602, the coil spring 603 is squeezed. When the power unit 202 drives the transmission shaft 401 to rotate, thereby driving the multiple flame heads 104 to move along the width direction of the vehicle body 1, when the half gear 602 is geared with the full gear 601, the transmission shaft 401 drives the half gear 602 to rotate through the full gear 601, thereby driving the rotating shaft 201 to rotate clockwise. The rotating shaft 201 drives the slip ring 301 to rotate clockwise through the limiting slide groove 303 and the limiting slider 302, thereby driving the flame heads 104 to swing clockwise. At the same time, the rotating shaft 201 squeezes the coil spring 603, and the coil spring 603 applies a counterclockwise elastic force to the rotating shaft 201 after being squeezed. When the full gear 601 is disengaged from the half gear 602, the transmission shaft 401 continues to drive the flame heads 104 to reciprocate along the width direction of the vehicle body 1. Under the action of the elastic force of the coil spring 603, the rotating shaft 201 rotates counterclockwise, thereby driving the flame heads 104 to swing counterclockwise. The reciprocating rotation mechanism of the present device can drive the flame head 104 to swing back and forth along the length direction of the vehicle body 1 without the use of an additional power device 202, and under the action of the full gear 601, the half gear 602 and the coil spring 603 of the reciprocating mechanism, the reciprocating motion of the flame head 104 along the width of the vehicle body 1 and the reciprocating swinging of the flame head 104 along the length direction of the vehicle body 1 are coordinated, thereby improving the uniformity of heating the lower supporting layer at the damaged part.

[0029] As a preferred solution, Figure 4-Figure 7As shown, a through-axis hole 501 is provided in the transmission shaft 401, and a screw rod 502 is rotatably connected in the through-axis hole 501. A threaded sleeve 503 is threadedly connected to the screw rod 502, and a clamping block 504 is provided on the threaded sleeve 503. A through-slot 506 along the axial direction of the transmission shaft 401 is provided on the transmission shaft 401. Each cam 402 is rotatably connected to the transmission shaft 401, and each cam 402 is provided with a clamping slot 505. By rotating the screw rod 502, the clamping block 504 can be driven to move along the length direction of the through-slot 506, so that the clamping block 504 is clamped with the clamping slot 505 on different cams 402, so that the transmission shaft 401 can drive the cam 402 clamped with the clamping block 504 to rotate through the clamping block 504. When multiple nozzles are spraying fire to heat the lower bearing layer at the damaged part, the screw rod 502 is rotated to drive the threaded sleeve 503 to move along the axial direction of the screw rod 502, and the threaded sleeve 503 drives the block 504 thereon to move along the axial direction of the screw rod 502, thereby driving the block 504 to slide along the length direction of the through groove 506, so that the block 504 is engaged with different cams 402. When the slot 505 on each cam 402 is engaged with the block 504, the transmission shaft 401 can drive multiple cams 402 to rotate simultaneously through the block 504, thereby driving multiple nozzles. It synchronously reciprocates along the width direction of the vehicle body 1, thereby uniformly heating the lower supporting layer at the damaged part. When the clamping block 504 is only engaged with the clamping groove 505 on one part of the cams 402, the transmission shaft 401 drives one part of the cams 402 to rotate through the clamping block 504, while the other cams 402 do not rotate. The nozzle indirectly connected to this part of the non-rotating cams 402 only swings back and forth along the length direction of the vehicle body 1, thereby specifically heating the area of ​​the lower supporting layer with a lower temperature along the width direction of the vehicle body 1, thereby ensuring the uniformity of the temperature field of the lower supporting layer.

[0030] As a preferred solution, Figure 3 and Figure 4As shown, a temperature detector 106 is provided on the rotating shaft 201, and the temperature detector 106 is electrically connected to a controller. The temperature detector 106 can perform temperature detection on multiple detection points along the axial direction of the transmission shaft 401, and each detection point corresponds to a cam 402. The screw rod 502 is connected to the third power unit 7, and the controller is electrically connected to the third power unit 7. When the real-time temperature value of one of the detection points is lower than the real-time temperature values ​​of the other detection points, the controller controls the third power unit 7 to rotate, so that the card block 504 is disengaged from the card slot 505 on the cam 402 corresponding to the detection point. By setting up a temperature detector 106, when the rotating shaft 201 drives multiple flame heads 104 to swing back and forth along the length direction of the vehicle body 1, the rotating shaft 201 simultaneously drives the temperature detector 106 to perform temperature detection on multiple detection points of the lower supporting layer along the width direction of the vehicle body 1. Each detection point corresponds to a cam 402. When the real-time temperature value of one of the detection points is lower than the real-time temperature values ​​of the other detection points, the controller controls the third power unit 7 to rotate so that the block 504 is disengaged from the card slot 505 on the cam 402 corresponding to the detection point. At this time, when the transmission shaft 401 rotates, the cam 402 does not rotate, so that the area corresponding to the detection point is specially heated to increase the real-time temperature of the lower temperature area in the lower supporting layer and improve the uniformity of the temperature field of the lower supporting layer.

[0031] As a preferred solution, Figure 1 and Figure 2 As shown, the controller is electrically connected to the power unit 202, and a first temperature threshold is preset in the controller. Before the unloading mechanism 101 of the repair equipment unloads, the controller controls the power unit 202 and the multiple flame heads 104 to operate, driving the multiple flame heads 104 to heat the lower support layer below the unloading mechanism 101 with flames. When the real-time temperature value of the lower support layer below the unloading mechanism 101 reaches the first temperature threshold, the controller controls the unloading mechanism 101 to unload. Since the optimal construction environment temperature of the composite phase-change asphalt mixture is 20°C-30°C, the first temperature threshold is preset at 20°C. Before the unloading mechanism 101 unloads, the controller controls the power unit 202 to operate, heating the damaged road surface below the unloading mechanism 101, i.e., the lower support layer, with flames. When the real-time temperature value of the lower support layer reaches the first temperature threshold, the unloading mechanism 101 unloads toward the damaged area of ​​the road surface, ensuring that the composite phase-change asphalt mixture on the lower support layer is within the optimal construction environment temperature range.

[0032] As a preferred solution, Figure 1 and Figure 2As shown, a second temperature threshold is preset within the controller. During the process of the repair equipment's compacting mechanism 102 compacting the composite phase-change asphalt mixture layer discharged from the damaged area, the controller controls the power unit 202 and the multiple flame heads 104 to operate, driving the multiple flame heads 104 to heat the composite phase-change asphalt mixture layer beneath the compacting mechanism 102. When the real-time temperature of the composite phase-change asphalt mixture layer reaches the second temperature threshold, the compacting mechanism 102 is controlled to compact the composite phase-change asphalt mixture layer. As the compacting mechanism 102 compacts the composite phase-change asphalt mixture, the composite phase-change asphalt mixture layer slowly dissipates heat. By controlling the power unit 202 and the multiple flame heads 104, the multiple flame heads 104 simultaneously heat and insulate the composite phase-change asphalt mixture while the compacting mechanism 102 compacts the composite phase-change asphalt mixture layer. This ensures that the composite phase-change asphalt mixture layer is always at the optimal construction environment temperature, further ensuring the uniformity of the density of the repaired pavement.

[0033] As a preferred solution, Figure 1 and Figure 2 As shown, the flame spraying range of the flame spraying head 104 can be adjusted. By adjusting the flame spraying range of the flame spraying head 104, it can adapt to the repair of damage of different sizes on the smart highway pavement, thereby improving the applicability of the entire equipment.

[0034] As a preferred solution, Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the flame head 104 is detachably connected to the slip ring 301.

[0035] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
