Description

Technical Field

[0001] This invention relates to the field of road repair equipment technology, specifically to an integrated paving system for asphalt road repair. Background Technology

[0002] In-situ thermal recycling is a preventative maintenance technique that involves heating and milling asphalt pavement using specialized equipment, then adding new asphalt, mixtures, and recycling agents on-site. Through processes such as mixing, paving, and compaction, the surface of the old pavement is repaired in one step. It has advantages such as requiring less new materials, minimizing road occupancy during construction, and generating no waste.

[0003] Existing in-situ thermal recycling equipment typically requires 2-3 sets of heating vehicles and one set of loosening vehicles, or 3-4 sets of heating vehicles and one ferrule vehicle, followed by a receiving and mixing vehicle. Each set of vehicles is over ten meters long, and the sheer size of the equipment necessitates maintaining a safe distance (approximately 2 meters) between the vehicles. Therefore, the existing in-situ thermal recycling process has the following problems:

[0004] First, the safe distance between equipment delays the time it takes for the next piece of equipment to enter the work area, increases heat loss, and thus increases energy consumption.

[0005] Second, the use of multiple sets of equipment results in an excessively long equipment chain, making it difficult to apply in municipal roads;

[0006] Third, additional pavers are required for construction, which increases the difficulty of equipment coordination and construction.

[0007] Therefore, we propose an in-situ thermal regeneration system suitable for urban road surface layers to achieve a unified approach to equipment lightweighting, energy saving, and scheduling. Summary of the Invention

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0052] Example 1:

[0053] Please see Figure 1-12This invention provides a technical solution: an integrated paving system for asphalt pavement repair, comprising a vehicle body 10, and a preheating adjustment mechanism 20, a milling mechanism 40, a waste material recycling mechanism 71, a mixing mechanism 72, a chain-type heating and feeding mechanism 50, and a paving mechanism 60 installed on the vehicle body 10. The vehicle body 10 adopts existing technology and has a power system and a steering system, enabling it to move and rotate. An operating platform and an infrared recognition system are configured on the vehicle body 10, allowing it to automatically move along the road. The operating platform can receive remote control signals, and in sections where automatic movement is inconvenient, the vehicle body 10 can be manually controlled via remote control. The movement of the vehicle body 10 drives the movement of this equipment.

[0054] A transverse support 25 is rotatably connected to the lower side of the preheating adjustment mechanism 20, and a heating module 30 is installed on the lower side of the transverse support 25. The transverse support 25 acts as a cantilever for connection, offsetting the position of the heating module 30 from the preheating adjustment mechanism 20. The preheating adjustment mechanism 20 rotates the heating module 30 via the transverse support 25, positioning the heating module 30 in front, to the left, or to the right of the preheating adjustment mechanism 20. The heating module 30 includes several heating plates 31 connected end to end; each heating plate 31 is 2 meters wide, and its length can be adjusted according to needs. The total length of all heating plates 31 when unfolded is 3.75 meters. Existing lane widths vary; for example, the width of motor vehicle lanes is 3.5 meters or 3.75 meters, while the width of bicycle lanes is 2 meters. During road regeneration, the road surface layer (approximately 4 cm below the road surface) is heated using the heating module 30. When heating a 2-meter-wide road, the width of the heating plate 31 is aligned with the width of the road. When the section to be heated is located on the lower left side of the vehicle body 10, the heating module 30 can be rotated using the preheating adjustment mechanism 20 to position the heating plate 31 on the heating module 30 on the lower left side of the vehicle body 10. Similarly, when the section to be heated is located on the lower right side of the vehicle body 10, the heating plate 31 is positioned on the lower right side of the vehicle body 10. When heating a 3.5-meter-wide road, the heating module 30 is positioned on the lower front side of the vehicle body, and then part of the heating plate 31 is deployed, with a total deployed length of 3.5 meters, aligned with the lane width. When heating a 3.75-meter-wide road, all heating plates 31 are fully deployed, with a total deployed length of 3.75 meters, aligned with the lane width.

[0055] The heating plates 31 are connected by a sealed flexible connection to avoid heat loss. For example, the heating plates 31 are infrared radiation heating plates that directly radiate heat to the road surface. The heating plates 31 are connected by a corrugated pipe to provide mechanical strength, and a fluororubber sealing layer is constructed at the connection point of the heating plates 31. For power supply, a power generation facility can be installed on the vehicle body 10 to supply power to electrical equipment. The heating module 30 also includes a fixed bracket, with the lower end of the transverse bracket 25 welded to the fixed bracket. The heating plate 31 includes a fixed heating plate and a movable heating plate. The fixed heating plate is installed on the lower side of the fixed bracket, and a buffer material, such as fluororubber, can be filled between the fixed heating plate and the fixed bracket to enhance the stability of the fixed heating plate. The movable heating plate extends beyond both ends of the fixed bracket and is movably connected to each other, allowing rotation. By unfolding the movable heating plate, the total length of the heating plate 31 can be extended, thus adapting to asphalt roads of different widths.

[0056] Extending brackets 34 are slidably connected to both ends of the fixed bracket. Guide rails can be installed on the fixed bracket, and sliders can be installed on the extending brackets 34. Through the cooperation of the sliders and guide rails, the extending brackets 34 can slide along the fixed bracket. When the two extending brackets 34 move away from each other, they can push the folded heating plate 31 to unfold, extending the total length of the heating plate 31. A winding mechanism is installed on the extending brackets 34. The opposite ends of the first and last heating plates 31 are connected to the adapter plate 32. The other end of the adapter plate 32 is connected to the traction rope 35. The traction rope 35 is connected to the winding mechanism, which is used to wind up or unwind the traction rope 35. When the two extending brackets 34 move away from each other, the winding mechanism unwinds the traction rope 35, allowing the heating plate 31 to unfold. When the two extending brackets 34 move closer to each other, the winding mechanism winds up the traction rope 35. The traction rope 35 pulls the heating plate 31 through the adapter plate 32 to complete the folding action. A bidirectional push rod 33 is mounted on the outer side of the fixed bracket; the telescopic ends on both sides of the bidirectional push rod 33 are connected to the two side extension brackets 34 respectively, so as to drive the two side extension brackets 34 to move away from or towards each other. A photoelectric encoder can be equipped on the telescopic end of the bidirectional push rod 33 to monitor the position of the telescopic end in real time, so as to achieve precise distance control.

[0057] Adjacent heating plates 31 are connected in series in the circuit. When powered on, the circuit at the beginning and end of the unfolded heating plate 31 is connected to complete the circuit connection. For example, conductive posts 301 are provided on the outer side of the heating plates 31 at both ends of the fixed bracket, and hollow posts 302 are installed on the expansion bracket 34. Conductive plates 303 are slidably inserted into the inner side of the hollow posts 302. After the conductive plates 303 move down and contact the conductive posts 301, the circuit connection is completed. Hollow posts 302 are provided on both sides of the expansion bracket 34 to ensure that the newly unfolded heating plates 31 on both sides can be connected to the circuit. A lifting rod 305 is installed at the top of the hollow column 302. An insulating column 304 is connected to the telescopic end of the lifting rod 305. The insulating column 304 is slidably inserted into the inner side of the hollow column 302, and its lower end is connected to the conductive plate 303. When the heating plate 31 needs to be folded or unfolded, the lifting rod 305 drives the conductive plate 303 to rise and disconnect it from the conductive column 301, and then the expansion bracket 34 is controlled to slide. A temperature sensor can also be installed on the fixed bracket to detect the temperature of the heating plate 31. The heating temperature of the heating plate 31 can be controlled by adjusting the current flowing through the heating plate 31 via the control console.

[0058] There are two sets of milling mechanisms 40, which are staggered one after the other. The overall milling width is increased by sliding the working ends of the two sets of milling mechanisms 40 to both sides. For example, the working end of one set of milling mechanisms 40 is 2 meters long. When milling a 2-meter-wide asphalt road, only one set of milling mechanisms 40 is used. When milling a 3.5-meter-wide asphalt road, the overlap area of ​​the two sets of milling mechanisms 40 is 0.5 meters. When milling a 3.75-meter-wide asphalt road, the overlap area of ​​the two sets of milling mechanisms 40 is 0.25 meters.

[0059] The milling mechanism 40 includes a top plate 41 fixed to the vehicle body 10, and a middle plate 42 slidably connected to the lower side of the top plate 41. A guide rail is installed below the top plate 41, and a slider is installed on the middle plate 42. The middle plate 42 is slidably connected to the top plate 41 through the cooperation of the slider and the guide rail. A milling traverse mechanism for driving the middle plate 42 to slide is installed on the lower side of the top plate 41. The milling traverse mechanism is used to push the middle plate 42 to slide left and right. The milling traverse mechanism can be driven by a lead screw. The optical shaft of the lead screw is connected to the top plate 41 through a bearing, and the middle plate 42 is connected to the lead screw through a ball nut. Then, a servo motor drives the lead screw to drive the middle plate 42 to slide left and right.

[0060] A base plate 43 is rotatably connected to the lower end of the middle plate 42. A milling end 44 is rotatably connected to the working end of the base plate 43, and a milling cutter is provided on the outer side of the milling end 44. A pull plate 48 and a swing push rod 47 are installed on the lower side of the middle plate 42. The middle plate 42 and the pull plate 48 can be slidably connected through the cooperation of the guide rail and the slider. The telescopic end of the swing push rod 47 is connected to the pull plate 48 and is used to push the pull plate 48 to slide. A connecting rod 49 is hinged between the pull plate 48 and the base plate 43. The swing push rod 47 drives the base plate 43 to swing and rise and fall through the pull plate 48 and the connecting rod 49, controlling the milling end 44 to contact or leave the asphalt road. A pressure sensor can be installed between the telescopic end of the swing push rod 47 and the pull plate 48 to detect the pressure between the milling end 44 and the asphalt road.

[0061] Both ends of the milling end 44's rotating shaft are connected to a first-order pulley. A drive shaft 45 is rotatably connected to the lower end of the base plate 43. Both ends of the drive shaft 45 are connected to second-order pulleys, which are connected to the first-order pulleys. The first-order pulleys on both sides drive the milling end 44 to rotate, preventing excessive torque on one end of the milling end 44's rotating shaft. A milling motor 46 is mounted on the outer side of the base plate 43. A drive pulley is fitted onto the outer side of the output shaft of the milling motor 46, and a driven pulley is fitted onto the outer side of the drive shaft 45. The drive pulley and driven pulley are connected.

[0062] There are two sets of paving mechanisms 60, which are staggered one after the other. The overall paving width is increased by sliding the working ends of the two sets of paving mechanisms 60 to both sides. The paving mechanism 60 includes a screed 64 (the screed 64 adopts existing technology and is used for material feeding, heating, vibration and compaction, which will not be described in detail here) and a paving fixing plate 62 fixed on the vehicle body 10. A paving support 61 is provided on the outer side of the screed 64 and is slidably connected to the paving fixing plate 62. The paving support 61 and the paving fixing plate 62 are connected by a slider and guide rail to achieve free sliding. A paving transverse mover 63 is installed on the outer side of the paving fixing plate 62 to drive the paving support 61 to slide. The paving transverse mover 63 adopts a combination of motor and lead screw. The motor is installed on the paving fixing plate 62, and the optical shaft section of the lead screw is connected to the paving fixing plate 62 through bearings. One end of the paving fixing plate 62 is connected to the output shaft of the motor. The paving support 61 is screwed to the lead screw by ball nuts.

[0063] The waste material recycling mechanism 71 collects the waste material milled by the milling mechanism 40 and conveys it to the mixing mechanism 72. Then, new materials such as recycling agent, asphalt, and mineral aggregates are added to the mixing mechanism 72 and mixed together with the waste material. The mixture is then conveyed to the chain-type heated feeding mechanism 50, and finally to the paving mechanism 60. The waste material recycling mechanism 71, the mixing mechanism 72, and the chain-type heated feeding mechanism 50 all use existing technology and will not be described in detail here.

[0064] There are two sets of chain-type heating and feeding mechanisms 50, each corresponding to a set of paving mechanisms 60. When repairing a two-meter-wide road, only one set of paving mechanisms 60 is needed. Therefore, a material distribution mechanism needs to be designed to ensure that the material only enters a certain set of chain-type heating and feeding mechanisms 50. Thus, a material distribution mechanism is set between the mixing mechanism 72 and the chain-type heating and feeding mechanism 50.

[0065] The material distribution mechanism includes a material distribution housing 74 fixed on the vehicle body 10. A heat insulation plate 73 is installed on the outside of the material distribution housing 74. A conduit driver 75 is installed on the outside of the heat insulation plate 73. The conduit driver 75 can be a combination of a servo motor and a reducer. The output shaft of the servo motor is connected to the input shaft of the reducer. The output shaft of the reducer extends into the inside of the material distribution housing 74 and is connected to the outside of the adapter pipe 76. The adapter pipe 76 is driven to rotate by the conduit driver 75.

[0066] A curved pipe 77 is provided on the upper side of the transfer pipe 76. The curved pipe 77 can be a corrugated pipe to avoid interfering with the normal rotation of the transfer pipe 76. A feed pipe 78 that penetrates the material distribution shell 74 is connected to the upper side of the curved pipe 77. The feed pipe 78 is connected to the discharge pipe of the stirring mechanism 72. An inverted Y-tube is installed on the lower side of the material distribution shell 74, so that the material distribution mechanism has two discharge ports, namely the first discharge pipe 791 and the second discharge pipe 792. The first discharge pipe 791 and the second discharge pipe 792 each correspond to a chain heating and feeding mechanism 50. The Y-tube also has a discharge port on each side, connected to discharge pipe 791 (number one) and discharge pipe 792 (number two), respectively. Therefore, the material distribution casing 74 has discharge port 793 (number one), discharge port 794 (number two), and discharge port 795 (number three). Discharge port 793 is connected to discharge pipe 791; material entering discharge port 793 will only be discharged from discharge pipe 791. Discharge port 795 is connected to discharge pipe 792; material entering discharge port 795 will only be discharged from discharge pipe 792. Discharge port 794 is connected to both discharge pipes 791 and 792; material entering discharge port 794 is diverted to discharge pipes 791 and 792. The guide pipe driver 75 rotates the adapter pipe 76, switching the discharge ports so that material can enter different discharge ports. The length of a single screed 64 is also 2 meters. When repairing a 2-meter-wide lane, the material is selectively introduced into the chain heating and feeding mechanism 50 on one side, and then transported to the corresponding structure of a single screed 64, so that only the asphalt in the 2-meter-wide lane is paved.

[0067] The push rods in this device are all hydraulic or pneumatic, and the vehicle body 10 is equipped with corresponding power facilities; for example, hydraulic push rods are equipped with hydraulic systems, and pneumatic push rods are equipped with pneumatic systems.

The lower side of the outer frame 21 and the vehicle body 10 are provided with a through-plate groove. An inner frame 22 is slidably installed on the inner side of the outer frame 21. A deflector frame 26 is rotatably connected to the lower side of the inner frame 22. The lower end of the deflector frame 26 passes through the vehicle body 10 and is welded to the transverse support 25.

[0070] A height adjustment push rod 23 is installed on the inner side of the outer frame 21. The telescopic end of the height adjustment push rod 23 is connected to the inner frame 22. The heating module 30 is raised and lowered by the height adjustment push rod 23. A reversing motor 24 is installed on the inner side of the inner frame 22. The output shaft of the reversing motor 24 is connected to the reversing frame 26. The heating module 30 is rotated by the reversing motor 24.

[0071] A positioning plate 27 is movably installed on the underside of the vehicle body 10. The deflector frame 26 passes through the positioning plate 27 and is slidably connected to it. The outer side of the positioning plate 27 has four positioning slots, and the included angle between adjacent positioning slots is 90°. A positioning block 29 and a positioning push rod 28 that drives the positioning block 29 to slide are slidably connected on the underside of the vehicle body 10. The positioning block 29 is adapted to the positioning slot. By pushing the positioning block 29 into the positioning slot through the positioning push rod 28, the positioning plate 27 can be fixed, and then the deflector frame 26 can be fixed through the positioning plate 27.

[0073] Please see Figure 1-2 and Figure 4 This invention provides a technical solution: an integrated paving system for asphalt pavement repair. Based on Embodiment 1, the winding mechanism includes a winding wheel 39. The shaft of the winding wheel 39 is connected to an extension bracket 34 via a bearing. One end of a traction rope 35 is fixed to the winding wheel 39. The winding wheel 39 winds up and unwinds the traction rope 35 by rotating. A gear rack 37 is installed on the fixed bracket, and a winding gear 38 is sleeved on the outside of the shaft of the winding wheel 39. The gear rack 37 meshes with the winding gear 38. When the extension bracket 34 slides, the winding gear 38 drives the winding wheel 39 to rotate. By adjusting the ratio of the number of rotations of the winding gear 38 to the displacement dimension of the extension bracket 34, the release length of the traction rope 35 on the winding wheel 39 is aligned with the displacement dimension of the extension bracket 34, thereby ensuring that the traction rope 35 is not too loose when it is loosened or tightened.

[0074] A clamping plate 36 is rotatably connected to the outer side of the extension bracket 34, and a coil spring 361 connects the clamping plate 36 and the extension bracket 34. A guide wheel 362 is rotatably connected to the other end of the clamping plate 36, and a traction rope 35 is wound around the groove of the guide wheel 362. The coil spring 361 drives the clamping plate 36 to swing, and the clamping plate 36 further adjusts the traction rope 35 via the guide wheel 362 to ensure that the traction rope 35 can be clamped. Simultaneously, when the heating plate 31 unfolds, because the heating plate 31 has a plate-like structure, the coil spring 361 contracts to compensate, releasing excess traction rope 35 to ensure that the heating plate 31 can unfold normally.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics.
