[0004] Regarding the above-mentioned related technologies, before repairing the road, it is necessary to first determine the location to be repaired, then the workers will aim the spraying piece at the area to be repaired, and finally use the spraying piece to spray. During this process, adjusting the equipment wastes a lot of time, resulting in low repair efficiency. Summary of the Invention

[0005] In order to improve the efficiency of road repair, the present application provides a municipal asphalt pavement leveling and paving system.

[0006] This application provides a municipal asphalt pavement leveling and paving system, which adopts the following technical solutions:

[0007] A municipal asphalt pavement leveling and paving system includes a vehicle body, an asphalt tank mounted on the vehicle body, and a pressure wheel mounted on the rear of the vehicle body. It also includes a horizontal transverse movement mechanism arranged at the bottom of the vehicle body and a position detection mechanism arranged on the horizontal transverse movement mechanism. A mounting plate is provided on the moving part of the horizontal transverse movement mechanism, and a sprinkler mechanism connected to the asphalt tank is mounted on the mounting plate. The position detection mechanism is arranged on the mounting plate. The position detection mechanism can detect the position to be repaired under the drive of the horizontal transverse movement mechanism, so that the sprinkler mechanism moves to the position to be repaired and sprays asphalt.

[0008] By adopting the above technical solution, the paving device is transported to the road surface that needs to be repaired, and the horizontal lateral movement mechanism is controlled to work. The horizontal lateral movement mechanism can drive the position detection mechanism to move and detect the road surface. The area to be repaired is found through the position detection mechanism, and then the asphalt is sprayed on the area to be repaired through the sprinkler mechanism. During this process, workers do not need to move the equipment to align the spray port with the area to be sprayed, which shortens the time for adjusting the equipment and improves the efficiency of road repair.

[0009] Optionally, the position detection mechanism includes an image sensor and a controller, wherein the image sensor is mounted on the mounting plate and is located on a side away from the vehicle body; the controller is electrically connected to the horizontal traverse mechanism, the image sensor and the sprinkler mechanism respectively.

[0010] By adopting the above technical solution, the controller controls the operation of the horizontal lateral movement mechanism and the image sensor, and the horizontal lateral movement mechanism drives the mounting plate to move. When the image sensor detects the area to be repaired, the image sensor transmits the image signal to the controller, and the controller controls the sprinkler mechanism to spray asphalt. The asphalt in the asphalt tank is sprayed on the area to be repaired, and then flattened by the pressure wheel, thereby realizing road repair.

[0011] Optionally, the horizontal transverse movement mechanism includes a first transverse movement member and a second transverse movement member installed on the transverse movement end of the first transverse movement member, the mounting plate is installed on the transverse movement end of the second transverse movement member, and the first transverse movement member and the second transverse movement member are both electrically connected to the controller.

[0012] By adopting the above technical solution, the first transverse moving member and the second transverse moving member are controlled by the controller, so that the mounting plate can move over a large range at the bottom of the vehicle body. During the movement, the image sensor can be used to quickly find the position to be repaired, thereby repairing the road surface and improving work efficiency.

[0013] Optionally, a distance sensor is provided on the mounting plate, the distance sensor is located on a side of the mounting plate facing away from the vehicle body, and the distance sensor is electrically connected to the controller.

[0014] By adopting the above technical solution, the distance sensor can first measure the distance between it and the road surface. When the image sensor detects the location of the pothole to be repaired, the image sensor then detects the distance between it and the bottom of the pothole, thereby calculating the depth of the pothole. The controller uses the depth data to control the spraying time of the sprinkler mechanism, thereby controlling the amount of asphalt sprayed, thereby repairing potholes of different depths.

[0015] Optionally, the mounting plate is further provided with a smoothing mechanism for smoothing the asphalt at the repair position after sprinkler irrigation, and a vibrating mechanism for vibrating the asphalt during the smoothing process. The smoothing mechanism can drive the vibrating mechanism to automatically vibrate during the smoothing process. The mounting plate is also provided with a flipping mechanism for driving the smoothing mechanism and the vibrating mechanism to flip to the bottom of the sprinkler irrigation mechanism.

[0016] By adopting the above technical solution, when the sprinkler mechanism completes the asphalt spraying on the road surface to be repaired, the flipping mechanism drives the smoothing mechanism and the vibrating mechanism to flip to the bottom of the sprinkler mechanism, and the smoothing mechanism smoothes the asphalt on the repaired area. During the process of the smoothing mechanism smoothing the asphalt, the smoothing mechanism can drive the vibrating mechanism to vibrate the asphalt, so that the asphalt on the repaired area can be smoothed and compacted.

[0017] Optionally, the smoothing mechanism includes a base, a power member, a driving gear, a driven gear, a smoothing cylinder and a limit block, the base is mounted on the flip mechanism, the power member is mounted on the base, and the driving gear is coaxially sleeved and fixed on the output shaft of the power member;

[0018] The driven gear is fixed to the top of the smoothing cylinder, and an elliptical guide groove is provided on the top of the smoothing cylinder. The edge tooth surface of the driven gear is consistent with the guide groove. The end of the power member is slidably engaged in the guide groove, and the driving gear is meshed with the driven gear. A slide groove is provided on the base, and the limit block is rotatably connected to the driven gear and slidably engaged in the slide groove.

[0019] By adopting the above technical solution, when the flipping mechanism rotates the base to the position to be repaired, the power part drives the driving gear to rotate, and the driving gear drives the driven gear to rotate. At this time, the output end of the power part slides along the guide groove, and the limit block slides in the slide groove, causing the smoothing cylinder to move in an irregular curve. Since the asphalt at the position to be repaired is located in the smoothing cylinder, the smoothing cylinder moves and smoothes the asphalt at the position to be repaired.

[0020] Optionally, the vibrating mechanism includes a fixed cylinder fixedly mounted on the base and sleeved outside the smoothing cylinder, a vibrating plate slidably mounted in the smoothing cylinder along the bottom direction of the smoothing cylinder, a round table provided in the smoothing cylinder and fixedly connected to the upper surface of the vibrating plate, a plurality of pressing components that drive the round table to move toward the bottom direction of the smoothing cylinder, and a reset member that drives the vibrating plate to reset;

[0021] When the smoothing cylinder rotates in the fixed cylinder, the inner circumferential wall of the fixed cylinder successively drives each group of the pressing components to press the circular table, so that the circular table drives the vibrating plate to repeatedly vibrate the asphalt on the bottom of the smoothing cylinder.

[0022] By adopting the above technical solution, when the smoothing cylinder rotates irregularly in the fixed cylinder, it will drive each group of pressure components to press the round table in turn, so that the round table drives the vibrating plate to move toward the bottom of the smoothing cylinder, thereby realizing the vibration and flattening of the asphalt during the smoothing process of the smoothing cylinder, and the reset part can drive the vibrating plate to reset, so that the vibrating plate can move repeatedly in the smoothing cylinder to achieve repeated vibration of the asphalt.

[0023] Optionally, the pressing assembly includes a pressing rod slidably mounted on the side wall of the smoothing cylinder and an elastic member for driving the pressing rod to move in the direction of extending out of the smoothing cylinder, one end of the pressing rod extends out of the smoothing cylinder, and the other end slides and abuts against the inclined surface of the table.

[0024] By adopting the above technical solution, when the smoothing cylinder makes irregular movements in the fixed cylinder, the smoothing cylinder will drive the pressure rods to press backward against the inner wall of the fixed cylinder, causing the pressure rods to slide into the smoothing cylinder, and the ends of the pressure rods to push the inclined surface of the table, thereby causing the table to drive the vibrating plate to move toward the bottom of the smoothing cylinder to achieve vibration of the asphalt. When the smoothing cylinder is away from the inner wall of the fixed cylinder, the elastic member drives the pressure rods to reset, and under the action of the reset member, the vibrating plate is reset to achieve repeated vibration.

[0025] Optionally, a constant temperature control mechanism is further included, which includes a heating element and a thermometer. The heating element is arranged in the asphalt tank, and the thermometer is arranged outside the asphalt tank. The heating element and the thermometer are both electrically connected to the controller.

[0026] By adopting the above technical solution, when repairing the road, the thermometer can constantly detect the temperature of the asphalt in the asphalt tank and transmit the temperature signal to the controller. When the temperature of the asphalt is lower than the set value, the controller controls the heating element to generate heat, thereby heating the asphalt in the asphalt tank and keeping the asphalt at a higher fluid temperature, making it easier to repair potholes on the road at any time.

[0027] Optionally, the asphalt tank is provided with an insulation shell, the inner wall of the insulation shell is provided with a mounting groove, the heating element is installed in the mounting groove, the mounting groove is spiral-shaped, and the heating element is spirally installed in the mounting groove.

[0028] By adopting this technical solution, the insulation shell can insulate the heat generated by the heating element, reducing heat dissipation, allowing the heating element to heat the asphalt to a fluid state more quickly, and improving heating efficiency. The spiral heating element reduces space usage, allowing more heating elements to be installed in the mounting slot, thereby shortening the heating time of the heating element on the asphalt and improving heating efficiency.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The horizontal traverse mechanism can drive the position detection mechanism to perform mobile detection on the road surface. The position detection mechanism finds the area to be repaired, and then the asphalt is sprayed and flattened on the area to be repaired. During this process, workers do not need to move the equipment to align the spray nozzle with the area to be sprayed, which shortens the time for adjusting the equipment and improves the efficiency of road repair.

[0031] 2. The distance sensor can first measure the distance to the road surface, then detect the distance to the bottom of the pothole, thereby calculating the depth of the pothole. The controller controls the spraying time of the sprinkler mechanism, thereby controlling the amount of asphalt sprayed, so as to repair potholes of different depths;

[0032] 3. When the flip mechanism rotates the base to the position to be repaired, the power component drives the driving gear to rotate, and the driving gear drives the driven gear to rotate. At this time, the output end of the power component slides along the guide groove, and the limit block slides in the slide groove, causing the smoothing cylinder to move in an irregular curve. Since the asphalt at the position to be repaired is located in the smoothing cylinder, the smoothing cylinder moves and smoothes the asphalt at the position to be repaired;

[0033] 4. When the smoothing cylinder rotates irregularly in the fixed cylinder, it will drive each group of pressing components to press the round table in turn, so that the round table drives the vibrating plate to move toward the bottom of the smoothing cylinder, thereby realizing the vibration and flattening of the asphalt during the smoothing process of the smoothing cylinder, and the reset part can drive the vibrating plate to reset, so that the vibrating plate can move repeatedly in the smoothing cylinder to achieve repeated vibration of the asphalt.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-6 , further details of this application are given.

[0042] The embodiment of the present application discloses a municipal asphalt pavement leveling and paving system.

[0043] A municipal asphalt pavement leveling paving system, referring to Figure 1 and Figure 2 , including a vehicle body 1, an asphalt tank 11, a pressure wheel 12, a sprinkler mechanism 2, a position detection mechanism 4 and a horizontal transverse movement mechanism 3. Wheels are installed on the vehicle body 1, and the asphalt tank 11 is fixedly installed on the vehicle body 1. A plurality of liquid outlets are provided at the bottom of the asphalt tank 11, and the sprinkler mechanism 2 is connected to each liquid outlet.

[0044] Reference Figure 1 and Figure 2 The sprinkler mechanism 2 includes a plurality of solenoid valves installed on each liquid outlet and four liquid outlet hoses 21 connected to each solenoid valve. The liquid outlet hoses 21 are rubber hoses specially used for asphalt. The rubber hoses can withstand higher asphalt temperatures. The rubber hoses pass through the through slots and extend out of the bottom plate of the vehicle body 1.

[0045] The position detection mechanism 4 and the horizontal transverse movement mechanism 3 are both located below the bottom plate of the vehicle body 1. The position detection mechanism 4 can perform image recognition of potholes on the road surface, and the horizontal transverse movement mechanism 3 can drive the position detection mechanism 4 to move in the horizontal direction, thereby detecting the road surface below the bottom of the vehicle body 1 to find the area that needs to be repaired.

[0046] Reference Figure 2 and Figure 3The horizontal transverse mechanism 3 includes a first transverse member 31 and a second transverse member 32, both of which are linear motors. The second transverse member 32 slides on the transverse end of the first transverse member 31. A mounting plate 5 is fixedly mounted on the transverse end of the second transverse member 32. The position detection mechanism 4 is mounted on the mounting plate 5. Driven by the first and second transverse members 31 and 32, the position detection mechanism 4 can translate horizontally along the bottom of the vehicle body 1.

[0047] Reference Figure 2 and Figure 3 Position detection mechanism 4 includes an image sensor 41 and a controller. The surface of mounting plate 5 is parallel to the surface of the floor of vehicle body 1. Image sensor 41 is bolted to the center of mounting plate 5, located on the side of mounting plate 5 facing away from the floor of vehicle body 1. The detection probe of image sensor 41 is perpendicular to mounting plate 5 and faces the ground. Four mounting holes are provided in mounting plate 5. The liquid outlet ends of the rubber hoses are fixed to mounting plate 5 through the corresponding mounting holes. The liquid outlets of the four rubber hoses are all oriented toward the central axis of mounting plate 5.

[0048] During the movement of the vehicle body 1, the first transverse member 31 and the second transverse member 32 drive the mounting plate 5 to move, so that the image sensor 41 can identify the movement of the road surface. The image sensor 41 compares the identified image signal with the road surface image stored in advance. When a pothole or cracked road surface is identified, the image sensor 41 transmits the image signal to the controller. The controller controls the solenoid valve to open. At this time, the asphalt in the asphalt tank 11 is sprayed to the pothole or cracked area through the rubber hose.

[0049] When repairing the road surface, the size and depth of the potholes are different. In order to control the amount of asphalt spraying according to the depth of the potholes, refer to Figure 1 A distance sensor 51 is also fixed on the mounting plate 5 by bolts. The distance sensor 51 and the image sensor 41 are installed at intervals and are both located in the middle of the mounting plate 5. The sensing probe of the distance sensor 51 is perpendicular to the mounting plate 5 and is set toward the road surface. The distance sensor 51 is connected to the controller signal.

[0050] When the image sensor 41 detects a location that needs to be repaired, the controller controls the distance sensor 51 to detect the depth of the pothole, and changes the opening time of the solenoid valve according to the correspondence between the depth value and the spraying amount set in advance, so as to spray the road surface of different depths in an appropriate amount. When the spraying is completed, the pressure wheel 12 flattens the sprayed area, thereby completing the repair of the road surface.

[0051] In order to smooth the repaired area after spraying asphalt, refer to Figure 1 and Figure 2The mounting plate 5 is also provided with a smoothing mechanism 6 for smoothing the asphalt at the repair position after sprinkler irrigation, and a vibrating mechanism 7 for vibrating the asphalt during the smoothing process. The smoothing mechanism 6 can drive the vibrating mechanism 7 to automatically vibrate during the smoothing process. The mounting plate 5 is also provided with a flipping mechanism 52 for driving the smoothing mechanism 6 and the vibrating mechanism 7 to flip to the bottom of the sprinkler irrigation mechanism 2.

[0052] Reference Figure 2 、 Figure 3 and Figure 4 The smoothing mechanism 6 includes a base 61, a power member 62, a driving gear 63, a driven gear 64, a smoothing cylinder 65 and a limit block 66. The base 61 is mounted on the flip mechanism 52, and the power member 62 is mounted on the base 61. The power member 62 is a driving motor, and the driving gear 63 is coaxially sleeved and fixed on the output shaft of the power member 62.

[0053] The driven gear 64 is fixed to the top of the smoothing cylinder 65, and an elliptical guide groove 651 is provided on the top of the smoothing cylinder 65. The edge tooth surface of the driven gear 64 is consistent with the guide groove 651. The end of the power member 62 is slidably engaged in the guide groove 651, and the driving gear 63 is engaged with the driven gear 64. A slide groove 611 is provided on the base 61, and the limit block 66 is rotatably connected to the driven gear 64 and slidably engaged in the slide groove 611.

[0054] Reference Figure 3 、 Figure 4 and Figure 5 The vibrating mechanism 7 includes a fixed cylinder 71 fixedly mounted on the base 61 and sleeved outside the smoothing cylinder 65, a vibrating plate 72 slidably mounted in the smoothing cylinder 65 along the bottom direction of the smoothing cylinder 65, a round table 73 provided in the smoothing cylinder 65 and fixedly connected to the upper plate surface of the vibrating plate 72, a plurality of pressure components 74 that drive the round table 73 to move toward the bottom direction of the smoothing cylinder 65, and a reset member 75 that drives the vibrating plate 72 to reset. The reset member 75 adopts a spring.

[0055] When the smoothing cylinder 65 rotates irregularly in the fixed cylinder 71, it will drive each group of pressing components 74 to press the round table 73 in turn, so that the round table 73 drives the vibrating plate 72 to move toward the bottom of the smoothing cylinder 65, thereby realizing the vibration and flattening of the asphalt during the smoothing process of the smoothing cylinder 65, and the reset member 75 can drive the vibrating plate 72 to reset, so that the vibrating plate 72 can move repeatedly in the smoothing cylinder 65, thereby realizing repeated vibration of the asphalt.

[0056] Reference Figure 4 and Figure 5The pressing assembly 74 includes a pressing rod 741 slidably mounted on the side wall of the smoothing cylinder 65 and an elastic member for driving the pressing rod 741 to move in the direction of extending out of the smoothing cylinder 65. The elastic member also adopts a spring. One end of the pressing rod 741 extends out of the smoothing cylinder 65, and the other end slides and abuts on the inclined surface of the table 73.

[0057] When the smoothing cylinder 65 makes irregular movements in the fixed cylinder 71, the smoothing cylinder 65 will drive the pressure rods 741 to press backward against the inner wall of the fixed cylinder 71, causing the pressure rods 741 to slide into the smoothing cylinder 65, so that the ends of the pressure rods 741 push the inclined surface of the table 73, thereby causing the table 73 to drive the vibrating plate 72 to move toward the bottom of the smoothing cylinder 65, thereby vibrating the asphalt. When the smoothing cylinder 65 is away from the inner side wall of the fixed cylinder 71, the elastic member drives the pressure rods 741 to reset, and under the action of the reset member 75, the vibrating plate 72 is reset to achieve repeated vibration.

[0058] Furthermore, during the process of repairing the road surface, the asphalt needs to be in a fluid state at all times in order to improve the quality of the repair. Therefore, a constant temperature control mechanism 8 and a stirring mechanism 9 are provided inside and outside the asphalt tank 11.

[0059] Reference Figure 6 The constant temperature control mechanism 8 includes a heating element 81 and a thermometer 82. The heating element 81 and the thermometer 82 are both electrically connected to the controller. The heating element 81 is arranged on the inner wall of the asphalt tank 11, and the thermometer 82 is arranged on the outer wall of the asphalt tank 11. In this embodiment, the heating element 81 is an electric heating tube, which belongs to resistance heating. In other embodiments, the heating element 81 can also adopt induction heating, arc heating, infrared heating, etc., and any heating method that is beneficial to heating asphalt can be used.

[0060] Reference Figure 6 The outer fixed sleeve of the asphalt tank 11 is provided with an insulation shell 112. The side wall of the insulation shell 112 near the top is provided with a thread. The top cover of the asphalt tank 11 is provided with a cover. The cover thread is screwed to the top of the insulation shell 112. A spiral mounting groove 111 is opened on the inner wall of the insulation shell 112. The electric heating pipe is installed in the mounting groove 111. In order to increase the use area of ​​the electric heating pipe, the electric heating pipe is also arranged in a spiral shape.

[0061] The thermometer 82 is fixed to the inner wall of the asphalt tank 11 by bolts and extends into the asphalt. When the thermometer 82 detects that the temperature of the asphalt is lower than the set value, the controller controls the electric heating tube to heat up, thereby increasing the temperature of the asphalt near the asphalt tank 11. If the temperature at the center of the asphalt tank 11 has not yet reached the set temperature requirement, the stirring mechanism 9 is required to properly stir the asphalt inside the asphalt tank 11.

[0062] Reference Figure 6The stirring mechanism 9 includes a mounting frame 91, a driving member 92 and a stirring paddle 93. The mounting frame 91 is fixedly mounted on the inner wall of the cover by bolts. The driving member 92 adopts a servo motor. The stirring paddle 93 is coaxially fixedly mounted on the output shaft of the servo motor and is used to stir the asphalt in the asphalt tank 11 so that the asphalt can be fully and evenly stirred, which facilitates the electric heating pipe to uniformly heat the asphalt. In other embodiments, the driving member 92 can also be set to a brushless motor, a reduction motor and a variable frequency motor. Any driving member 92 that is beneficial to driving the stirring paddle 93 to fully stir the asphalt can be used.

[0063] The implementation principle of a municipal asphalt pavement leveling and paving system according to an embodiment of the present application is as follows: a paving device is transported to a road surface to be repaired, and a horizontal traverse mechanism 3 is controlled to operate. The horizontal traverse mechanism 3 can drive an image sensor 41 to detect movement of the road surface, and the image sensor 41 finds the area to be repaired;

[0064] The distance sensor 51 measures the distance to the road surface. When the image sensor 41 detects the location of the pothole to be repaired, the image sensor 41 then detects the distance to the bottom of the pothole to calculate the depth of the pothole. The controller uses this depth data to control the timing of the sprinkler mechanism 2, thereby controlling the amount of asphalt sprayed.

[0065] When the sprinkler mechanism 2 completes the asphalt spraying on the road surface to be repaired, the flipping mechanism 52 drives the smoothing mechanism 6 and the vibrating mechanism 7 to flip to the bottom of the sprinkler mechanism 2, and the smoothing mechanism 6 smoothes the asphalt on the repaired area. In the process of smoothing the asphalt by the smoothing mechanism 6, the smoothing mechanism 6 can drive the vibrating mechanism 7 to vibrate the asphalt, so that the asphalt on the repaired area can be smoothed and compacted.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
