Description

Technical Field

[0001] The present invention relates to the technical field of municipal road maintenance, in particular to a mobile repairing device for municipal asphalt roads. Background Art

[0002] In the field of municipal road maintenance, asphalt pavement is widely used due to its good driving comfort and convenient construction. However, with the increase in traffic volume and the influence of environmental factors, asphalt pavement is prone to cracks and other defects. If not repaired in time, the pavement structure will be further damaged, affecting the service life of the road and driving safety.

[0003] Currently, common asphalt road repair equipment primarily uses infrared heating to treat cracked areas. The basic principle is to heat a large area of ​​asphalt in the target area, softening and melting it. The asphalt is then manually raked with tools to redistribute it, and finally compacted using a vibratory compactor to restore the road surface's smoothness and strength. However, this repair method has significant shortcomings: First, cracks on roads are typically slender, unevenly distributed, and small in diameter. Uniformly heating a large area of ​​asphalt wastes energy and prolongs heating time, reducing work efficiency. Second, for longer cracks, multiple heating steps, manual raking, and compaction are required, which is cumbersome and time-consuming, significantly impacting traffic efficiency. Furthermore, large-scale heating can easily cause thermal stresses in the asphalt structure of surrounding undamaged areas, thereby reducing the overall stability and durability of the road. Summary of the Invention

[0004] In view of this, the present invention provides a mobile municipal asphalt road repair device, which can overcome the shortcomings of existing asphalt road repair equipment, which usually requires uniform heating of a large area of ​​asphalt when in use, which not only wastes energy, but also prolongs the heating time and reduces work efficiency.

[0028] Example: A mobile repair device for municipal asphalt roads, such as Figure 1-Figure 7 As shown, it includes a mobile body 1, a control panel 2, a battery 3, an electric push rod 4, a lifting frame 5, a mounting frame 6, an infrared heating tube 7, a controller 8, a vibrating steel wheel 36, a positioning component and a raking component. The control panel 2 is installed on the top right side of the mobile body 1, and the battery 3 is installed on the inner right side of the mobile body 1. The battery 3 is used to power the electrical components of the device. Electric push rods 4 are installed symmetrically on the front and rear sides of the lower part of the mobile body 1. A lifting frame 5 is connected between the telescopic rods of the four electric push rods 4. The bottom of the lifting frame 5 is an open design. Sixteen mounting frames 6 are evenly spaced inside the lifting frame 5. The inner lower part of each mounting frame 6 is installed with an infrared heating tube 7, and the inner upper part of each mounting frame 6 is installed with a controller 8. The controller 8 corresponds to the infrared heating tube 7 one by one and is electrically connected. A vibrating steel wheel 36 is installed on the bottom right side of the mobile body 1. The mobile body 1 is provided with a positioning component for locating cracks on the road surface, and the lifting frame 5 is provided with a raking component for raking the melted asphalt.

[0029] like Figure 4-Figure 6As shown, the positioning assembly includes a guide rod 9, a sliding frame 10, a connecting spring 11, a turntable 12, a connecting rod 13, a Hall sensor 14, a magnet 15 and a detection mechanism. A plurality of guide rods 9 are evenly spaced from front to back on the lower left side of the mobile body 1. Each guide rod 9 is slidably connected to a sliding frame 10. A connecting spring 11 is wound around the outside of each guide rod 9, and the two ends of the connecting spring 11 are respectively connected to the sliding frame 10 and the guide rod 9. The left part of each sliding frame 10 is rotatably connected to the turntable 12. The front side of each guide rod 9 is connected to a connecting rod 13. A Hall sensor 14 is installed at the bottom of the connecting rod 13. The front right part of each sliding frame 10 is connected to a magnet 15, which contacts and cooperates with the Hall sensor 14. The mobile body 1 is provided with a detection mechanism for detecting the moving distance of the mobile body 1; the detection mechanism includes a fixed rod 16 and a magnetic encoder 1601. The fixed rod 16 is connected to the lower left part of the front side of the mobile body 1. The magnetic encoder 1601 consists of a magnetic ring and a sensor. The magnetic ring is installed on the wheel rotation axis of the mobile body 1, and the sensor is installed at the lower part of the fixed rod 16. The sensor is used to detect the change of the magnetic field on the magnetic ring, so as to detect the number of rotations of the wheel of the mobile body 1 to know the moving distance of the mobile body 1.

[0030] like Figure 7 As shown, the raking assembly includes a bidirectional screw rod 17, a raking frame 1701, a dual-axis motor 18 and a pulley assembly 19. The lower inner side of each mounting frame 6 is connected to the bidirectional screw rod 17 for front-to-back symmetrical rotation. The raking frame 1701 is symmetrically threaded between the two bidirectional screw rods 17. The upper inner side of each mounting frame 6 is symmetrically installed with a dual-axis motor 18. The pulley assembly 19 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the end of the bidirectional screw rod 17 and the output shaft of the dual-axis motor 18. The flat belt is wound around the two pulleys so that the output shaft of the dual-axis motor 18 and the bidirectional screw rod 17 can be transmitted through the pulley assembly 19.

[0031] When the device is needed, it is first placed on the right side of the crack, and then the electric push rod 4 is used to drive the lifting frame 5 to move downward a specified distance. The lifting frame 5 will drive the guide rod 9, the sliding frame 10, the turntable 12, the connecting rod 13, the Hall sensor 14 and the magnet 15 to move downward. When the turntable 12 contacts the ground, the turntable 12 is blocked and stops moving downward, and the sliding frame 10 and the magnet 15 also stop moving downward, and the lifting frame 5 will drive the guide rod 9, the connecting rod 13 and the Hall sensor 14 to continue moving downward, and the connecting spring 11 is compressed, so that the Hall sensor 14 is separated from the magnet 15, and then the lifting frame 5 will stop moving downward.Then control the mobile body 1 to move to the left and gradually approach the crack, the turntable 12 will roll on the ground, and when a turntable 12 rolls to the crack, the corresponding connecting spring 11 will return to its original state, driving the corresponding sliding frame 10, turntable 12 and magnet 15 to move downward and reset, so that the magnet 15 contacts the Hall sensor 14, and the Hall sensor 14 detects the change in the magnetic field of the magnet 15 and sends a signal. After receiving the signal, the control panel 2 can determine the longitudinal coordinate data of the crack, and the mobile body 1 will continue to move to the left, and the turntable 12 will separate from the crack. At this time, the turntable 12 will move upward due to the pressure of the ground, and the corresponding connecting spring 11 will be compressed, driving the corresponding sliding frame 10 and magnet 15 to move upward. The magnet 15 is disengaged from the Hall sensor 14 when the mobile body 1 moves to the top of the crack. The mobile body 1 is controlled to stop moving. During the movement of the mobile body 1, the magnetic encoder 1601 can detect the distance the mobile body 1 moves to the left in real time, so that the distance the device moves from when the Hall sensor 14 sends a signal to when the mobile body 1 stops moving can be known, so as to determine the horizontal coordinate data of the crack. At this time, the control panel 2 will control the controller 8 located just above the crack to start working. The controller 8 controls the infrared heating tube 7 to start working, so that the infrared heating tube 7 only heats a small area around the crack until the asphalt in the area softens and melts. The control panel 2 will then The corresponding controller 8 stops working, and the controller 8 will control the infrared heating tube 7 to stop working. Then the control panel 2 will control the lifting frame 5 to continue to move downward, driving the rake frame 1701 to move downward until it contacts the melted asphalt, and control the corresponding dual-axis motor 18 to drive the bidirectional screw 17 intermittently forward and reverse rotation through the pulley assembly 19. The bidirectional screw 17 drives the rake frame 1701 to move back and forth. The rake frame 1701 can rake the asphalt to redistribute the asphalt evenly. Then the control panel 2 will control the dual-axis motor 18 to stop working, causing the rake frame 1701 to stop moving, and control the lifting frame 5 to move upward and reset, driving the rake frame 1701 to move upward and separate from the asphalt, and then control the moving The vehicle body 1 continues to move to the left. When the vibrating steel wheel 36 moves over the asphalt, it vibrates and compacts the asphalt. Repeating the above operation, the next crack can be located and repaired. If the crack is longer than the length of a single mounting frame 6, the rotating disks 12 can locate each part of the crack while the vehicle body 1 is moving. The control panel 2 can then determine which mounting frames 6 the crack passes under based on its shape and direction. This allows precise control of the infrared heating tubes 7 located directly above the crack to activate, while the remaining infrared heating tubes 7 are deactivated. This eliminates the need for large-scale melting of the road surface, reduces energy consumption and time consumption, and improves work efficiency.

[0032] like Figure 8 and Figure 9As shown, it also includes a liquid storage tank 20, a liquid suction pump 21, a liquid suction pipe 22, a connecting pipe 23, a diverter pipe 24 and an electronically controlled nozzle 25. The liquid storage tank 20 and the liquid suction pump 21 are connected to the left rear side of the interior of the mobile body 1. The liquid suction pump 21 is located on the left side of the liquid storage tank 20. The liquid suction pipe 22 is connected to the lower left part of the liquid storage tank 20 and the liquid inlet of the liquid suction pump 21 and remains in communication. The lower part of the mobile body 1 is connected to the connecting pipe 23, and the left end of the connecting pipe 23 is connected to the liquid outlet of the liquid suction pump 21 and remains in communication. A diverter pipe 24 is connected between the outer walls of multiple mounting frames 6, and the right end of the connecting pipe 23 is connected to the diverter pipe 24 and remains in communication. Multiple electronically controlled nozzles 25 are evenly spaced and installed on the diverter pipe 24.

[0033] In the initial state, the liquid storage tank 20 is filled with a certain amount of regeneration liquid; when the rake frame 1701 is raking the asphalt, the control panel 2 will control the liquid extraction pump 21 to start working. The liquid extraction pump 21 can extract the regeneration liquid in the liquid storage tank 20 through the liquid extraction pipe 22, and transport the regeneration liquid to the diversion pipe 24 through the connecting pipe 23. At the same time, the control panel 2 can know which electric-controlled nozzles 25 the cracks have passed under according to the shape and direction of the cracks, and control the corresponding electric-controlled nozzles 25 to open, so that the electric-controlled nozzles 25 can spray the regeneration liquid on the melted asphalt. The regeneration liquid and the melted asphalt can be mixed by raking the rake frame 1701, and the viscosity of the asphalt can be restored by the regeneration liquid, ensuring the overall stability and durability of the subsequent road surface. Then the control panel 2 will control the electric-controlled nozzles 25 to close and control the liquid extraction pump 21 to stop working.

[0034] like Figure 10 As shown, it also includes an air pump 26 and an air guide frame 27. The air pump 26 is installed on the left side of the interior of the mobile body 1, and the air guide frame 27 is connected to the middle left side of the mobile body 1, and the air inlet of the air guide frame 27 is connected to the air outlet of the air pump 26 and remains connected.

[0035] During the movement of the mobile body 1, the air pump 26 can be controlled by the control panel 2 to start working. The air pump 26 can deliver high-pressure air to the air guide frame 27, so that the bottom of the air guide frame 27 can blow air downward. When the air guide frame 27 passes over the top of the crack, the dust and impurities in the crack can be blown away, ensuring that subsequent work can be carried out stably.

[0036] like Figure 6 、 Figure 10 and Figure 11As shown, it also includes a storage frame 28, a first screw feeder 29, a mounting plate 30, a baffle plate 31, a second screw feeder 32, a discharge pipe 33, an elastic square tube 34 and a baffle rod 35. The storage frame 28 and the first screw feeder 29 are connected to the left front side of the interior of the mobile body 1, and the feed port of the first screw feeder 29 is connected to the bottom of the storage frame 28 and remains in communication. The left side of the lifting frame 5 is symmetrically connected to the front and back of the mounting plate 30, and the upper right side of the air guide frame 27 is connected to the baffle plate 31. The second screw feeder 32 is installed between the tops of the two mounting plates 30. The left side of the second screw feeder 32 is connected with multiple discharge pipes 33 at intervals from front to back and remains in communication. The discharge port of the first screw feeder 29 and the feed port of the second screw feeder 32 are connected with an elastic square tube 34 and remain in communication. The middle part of the front side of each sliding frame 10 is connected to a baffle rod 35.

[0037] When the lifting frame 5 is in the downward direction, the first screw feeder 30, the second screw feeder 32 and the discharge pipe 33 are driven to move downward, the elastic square tube 34 is stretched, and the discharge pipe 33 is separated from the blocking plate 31. At the same time, the lifting frame 5 drives the sliding frame 10, the turntable 12 and the blocking rod 35 to move downward. When the turntable 12 contacts the ground, the sliding frame 10, the turntable 12 and the blocking rod 35 all stop moving downward, and the lifting frame 5 continues to drive the mounting plate 30, the second screw feeder 32 and the discharge pipe 33 to move downward, so that the right side of the blocking rod 35 blocks the left end of the discharge pipe 33. During the movement of the mobile body 1, the first screw feeder 29 and the second screw feeder 32 can be controlled by the control panel 2 to start working, and the first screw feeder 29 The asphalt in the storage frame 28 can be transported to the second spiral feeder 32 through the elastic square tube 34, and the second spiral feeder 32 can spread the asphalt inside it evenly. When the turntable 12 moves to the crack, the corresponding sliding frame 10 will drive the turntable 12 and the blocking rod 35 to move downward, so that the corresponding blocking rod 35 no longer blocks the left end of the discharge pipe 33. At this time, the asphalt in the second spiral feeder 32 will fall to the lower left through the corresponding discharge pipe 33. When the turntable 12 moves to be separated from the crack, the corresponding sliding frame 10 will drive the turntable 12 and the blocking rod 35 to move upward, so that the blocking rod 35 blocks the left end of the discharge pipe 33 again, so that the crack can be automatically replenished. When the infrared heating tube 7 heats the small area around the crack, the solid asphalt in the crack can be heated and melted synchronously, ensuring that the road surface is flat after subsequent asphalt compaction.
