Description

Technical Field

[0001] This invention relates to the field of highway maintenance technology, and in particular to a highway construction and maintenance device. Background Technology

[0002] During highway construction, highway maintenance is necessary. Cars driving on the highway can easily cause damage to the edges of the highway. If the highway is not repaired and maintained in time, it can easily cause large-scale damage to the highway. Therefore, highway maintenance personnel will repair the edges of the highway.

[0003] Patent publication number CN211256614U discloses a highway crack repair device, including a base. A storage box is fixedly installed on the upper surface of the base by a fixing column. A bearing is snapped onto the upper surface of the storage box, and a rotating shaft is sleeved on the inner side wall of the bearing. The top end of the rotating shaft is fixedly connected to the output shaft of a drive motor. The drive motor is fixedly installed on the upper surface of the storage box. Several stirring rods are fixedly installed on the outer surface of the rotating shaft, and the bottom end of the rotating shaft is fixedly connected to the top end of a spiral feeding rod.

[0004] When highways need repair and maintenance, the discharge pipe is aligned with the damaged area, and then the asphalt is discharged from the discharge pipe to the damaged area through the rotation of the screw feeder. During the filling process, if the asphalt is not vibrated in time, the asphalt will not be laid compactly, which will easily lead to the asphalt being loose. The repaired highway will still be prone to damage. Now, a highway construction and maintenance device that can lay asphalt more compactly is being developed. Summary of the Invention

[0017] 4. This invention can flatten the top of the asphalt by moving the flattening frame left and right, which facilitates road repair and maintenance.

[0018] 5. This invention uses a pusher frame to move to the right to compress the hollow extrusion piece, thereby allowing the curing agent to be discharged onto the asphalt through the water outlet pipe, which can prevent the asphalt from losing moisture to a certain extent.

Detailed Implementation

[0038] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] A highway construction and maintenance device, such as Figures 1-2 As shown, the system includes a maintenance frame 1, a first telescopic frame 11, a sprayer 12, a vibration mechanism 2, and a pressing mechanism 3. The first telescopic frame 11 is connected to the left and right sides of the lower part of the maintenance frame 1. The left and right sides of the upper part of the maintenance frame 1 are connected to sprayers 12 for road maintenance. The spray heads of the sprayers 12 are located on the left and right sides of the bottom of the maintenance frame 1. A vibration mechanism 2 is provided between the first telescopic frames 11. The vibration mechanism 2 can vibrate the paved asphalt to make it more compact. The first telescopic frame 11 on the right side is provided with a pressing mechanism 3. When the vibration mechanism 2 moves down, the pressing mechanism 3 can automatically compact the edges of the asphalt.

[0041] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the vibration mechanism 2 includes a motor 21, a support frame 22, a rotating frame 23, a connecting frame 24, a second telescopic frame 25, a vibrating plate 26, and a pin 27. The upper part of the first telescopic frame 11 on the right has multiple evenly spaced locking holes. The support frame 22 is slidably connected to the first telescopic frame 11 on the right. The pin 27, which engages with the locking holes, is slidably connected to the support frame 22. Removing the pin 27 allows the support frame 22 to be adjusted vertically. The motor 21 is supported on the right side of the support frame 22. The output shaft of the motor 21 is connected to the rotating frame 23 on the left. A sliding block is slidably connected to the first telescopic frame 11 on the left. The right side of the sliding block is also rotatably connected to the rotating frame 23. The connecting frame 24 is rotatably connected to the lower part of the rotating frame 23. The lower part of the connecting frame 24 is rotatably connected to the second telescopic frame 25. The bottom of the second telescopic frame 25 is connected to the vibrating plate 26. The output shaft of the motor 21 drives the rotating frame 23 to rotate, thereby causing the vibrating plate 26 to move vertically to vibrate the asphalt.

[0042] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the pressing mechanism 3 includes a first pressure plate 31, an inclined plate 32, a telescopic rod 33, and a first telescopic spring 34. The inclined plate 32 is connected to the front and rear sides of the support frame 22. The lower front and rear sides of the first telescopic frame 11 on the right are connected to the telescopic rod 33. The first telescopic spring 34 is wound around the telescopic rod 33. The first pressure plate 31 is connected between the left sides of the telescopic rod 33. The first pressure plate 31 and the inclined plate 32 are pressed together. The left end of the first telescopic spring 34 is connected to the right side of the first pressure plate 31. The fixed end of the telescopic rod 33 is connected to the right end of the first telescopic spring 34. When the inclined plate 32 moves down to contact the first pressure plate 31, the first pressure plate 31 will move to the left to press the asphalt side.

[0043] When the edge of the road is damaged, it is necessary to repair and maintain the damaged area. Water can be poured into the sprayer 12, and the road construction and maintenance device can be moved to the damaged location. During the movement, the sprayer 12 can be turned on, spraying water onto the road to maintain its condition and prevent cracking. After the road construction and maintenance device reaches the damaged location, ensuring it is directly below the vibrating plate 26, the sprayer 12 is turned off. Asphalt can then be laid onto the damaged area. After laying, the first pressure plate 31 is positioned... The asphalt side is then positioned so that the pin 27 can be pulled forward, unlocking the support frame 22. The support frame 22 can then be moved downwards, causing the motor 21, rotating frame 23, connecting frame 24, second telescopic frame 25, and vibrating plate 26 to move downwards until the bottom of the vibrating plate 26 contacts the top of the asphalt. The pin 27 can then be reinserted between the support frame 22 and the locking hole, thus restricting the position of the vibrating plate 26. As the support frame 22 moves downwards, it causes the inclined plate 32 to move downwards. When the inclined plate 32 and the first pressure plate 3... Upon contact, the first pressure plate 31 moves to the left to automatically press the side of the asphalt. The telescopic rod 33 and the first telescopic spring 34 are pulled by the rope 52. Then, the motor 21 can be turned on. The output shaft of the motor 21 rotates, driving the rotating frame 23 to rotate. The rotation of the rotating frame 23 causes the connecting frame 24 to vibrate up and down continuously. The up and down vibration of the connecting frame 24 causes the second telescopic frame 25 and the vibrating plate 26 to also vibrate up and down continuously. In this way, the vibrating plate 26 can intermittently vibrate the asphalt, thereby compacting the asphalt. This makes it easier to repair and maintain damaged areas. After the repair and maintenance are completed, the motor 21 is turned off, and the pin 27 is removed again. Then, the support frame 22 drives the rotating frame 23, the connecting frame 24, the second telescopic frame 25 and the vibrating plate 26 to move upward and reset. The pin 27 is reinserted between the support frame 22 and the locking hole, which can reset the vibrating plate 26. The upward movement of the support frame 22 will drive the inclined plate 32 to move upward. When the inclined plate 32 and the first pressure plate 31 are separated, under the action of the first telescopic spring 34 and the telescopic rod 33, the first pressure plate 31 will move to the right to reset and release the side of the asphalt.

[0044] Example 2

[0045] Based on Example 1, such as Figure 1 , Figure 9 and Figure 10As shown, it also includes an adjustment mechanism 4 for convenient adjustment of the height of the vibrating plate 26. The adjustment mechanism 4 includes a worm 41, a worm wheel 42, a rack 43 and a first fixed frame 44. The first fixed frame 44 is connected to the upper part of the sliding block. The worm 41 is rotatably connected to the left side of the first fixed frame 44. The worm wheel 42 is rotatably connected to the left side of the sliding block. The worm wheel 42 and the worm 41 mesh. The rack 43, which meshes with the worm wheel 42, is connected to the left side of the first telescopic frame 11 on the left side. By rotating the worm 41, the worm wheel 42 can be driven to rotate. Under the action of the rack 43, the vibrating plate 26 can be adjusted downward.

[0046] When the vibrating plate 26 is adjusted downwards, the pin 27 can be pulled out. Then, rotating the worm gear 41 will drive the worm wheel 42 to rotate. Under the action of the rack 43, the worm wheel 42 will slowly roll downwards, thereby adjusting the rotating frame 23 and the vibrating plate 26 downwards. This makes it easier to adjust the position of the vibrating plate 26. After adjustment, the pin 27 can be reinserted between the support frame 22 and the locking hole to restrict the vibrating plate 26. When it is necessary to reset the vibrating plate 26 upwards, the pin 27 can be pulled out again, and then the worm gear 41 can be reversed to drive the worm wheel 42 to reverse, thereby moving the vibrating plate 26 upwards to reset.

[0047] like Figure 1 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes a scraping mechanism 5 for scraping impurities on the first pressure plate 31. The scraping mechanism 5 includes a scraper 51, a pull rope 52, a guide wheel 53, a sliding frame 54, and a reset assembly. The sliding frame 54 is slidably connected to the top of the first pressure plate 31. The scraper 51 for scraping impurities on the first pressure plate 31 is connected to the left side of the sliding frame 54. The lower part of the scraper 51 is located on the left side of the first pressure plate 31. The guide wheel 53 is rotatably connected to the front of the first pressure plate 31. The first extension of the front and right sides of the scraper 51... A pull rope 52 is connected between the lower front part of the retractable frame 11. The pull rope 52 passes around the guide wheel 53, and the guide wheel 53 can guide the pull rope 52. A reset assembly is provided at the upper rear part of the first pressure plate 31 to facilitate the pull and reset of the sliding frame 54. The reset assembly is connected to the sliding frame 54. The reset assembly includes a spring 55 and a second fixed frame 56. The second fixed frame 56 is connected to the upper rear part of the first pressure plate 31, and the spring 55 is connected to the second fixed frame 56. The front end of the spring 55 is fixedly connected to the sliding frame 54.

[0048] Before the first pressure plate 31 moves to the left and approaches the asphalt, the leftward movement of the first pressure plate 31 will fix the right end of the pull rope 52, and the rear end of the pull rope 52 will be pulled forward. In this way, the pull rope 52 will automatically pull the scraper 51 and the sliding frame 54 forward, and the spring 55 will be stretched. The scraper 51 moves forward and automatically cleans the impurities on the left side of the first pressure plate 31. This can prevent the impurities on the first pressure plate 31 from mixing into the asphalt, thereby affecting the compactness of the asphalt. When the first pressure plate 31 moves to the right to reset, the pull rope 52 will be released. Under the action of the spring 55, the sliding frame 54 and the scraper 51 will automatically move backward to reset.

[0049] like Figure 1 , Figure 14 and Figure 15 As shown, it also includes a leveling mechanism 6 for leveling the upper part of the asphalt. The leveling mechanism 6 includes a leveling frame 61, a second telescopic spring 62, and a slide rod 63. The slide rod 63 is connected to the front and rear sides of the lower part of the first telescopic frame 11. The leveling frame 61 is slidably connected between the slide rods 63. The right part of the leveling frame 61 is slidably connected to the right part of the first telescopic frame 11. Moving the leveling frame 61 to the right will level the upper part of the asphalt, thereby facilitating the leveling of the asphalt. The front and rear sides of the left part of the leveling frame 61 and the right part of the first telescopic frame 11 are all connected to the second telescopic spring 62 wound on the slide rod 63.

[0050] After the asphalt is laid and compacted, the asphalt is lower than the bottom of the leveling frame 61. In order to make the top of the asphalt more flat, the leveling frame 61 can be moved to the right. The second telescopic spring 62 is compressed. The rightward movement of the leveling frame 61 will flatten the top of the asphalt, which can better repair and maintain the road. Then release the handle. Under the action of the second telescopic spring 62, it will move to the left to reset.

[0051] like Figure 1 , Figure 16 , Figure 17 and Figure 18 As shown, it also includes a spraying mechanism 7 for spraying the curing agent onto the asphalt. The spraying mechanism 7 includes a storage bottle 71, a fixing block 72, a hollow extruder 73, a water outlet pipe 74, a third telescopic spring 75, and a second pressure plate 76. The fixing block 72 is connected to the lower front part of the first telescopic frame 11 on the right side. The storage bottle 71 for storing the curing agent is provided inside the fixing block 72. The second pressure plate 76 is slidably connected inside the storage bottle 71. The third telescopic spring 75 is connected between the left part of the second pressure plate 76 and the left part inside the storage bottle 71. The hollow extruder 73 is slidably connected to the left side of the storage bottle 71. The right side of the hollow extruder 73 is connected to the left side of the second pressure plate 76. The hollow extruder 73 and the flattening frame 61 are pressed together. When the flattening frame 61 moves to the right to press the hollow extruder 73, it will drive the second pressure plate 76 to move to the right to squeeze out the curing agent. The left side of the hollow extruder 73 is connected to the water outlet pipe 74 and is in communication with it.

[0052] The curing agent is injected into the storage bottle 71 in advance. When the pusher 61 moves to the right and contacts the hollow extruder 73, the hollow extruder 73 will move to the right, causing the second pressure plate 76 to move to the right. The third telescopic spring 75 is stretched, so the curing agent in the storage bottle 71 will be discharged onto the asphalt through the outlet pipe 74. This can cure the asphalt and prevent the asphalt from losing moisture to a certain extent. After the pusher 61 moves to the left and separates from the hollow extruder 73, the second pressure plate 76 and the hollow extruder 73 will move to the left and reset under the action of the third telescopic spring 75.

[0053] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
