Description

Technical Field

[0002] At present, urban roads are mainly made of cement pavement and asphalt pavement. With the traffic of vehicles on the road, some roads are prone to damage and usually need to be repaired with asphalt. At present, in the process of repairing the road, especially repairing the entire section of asphalt road, it is generally necessary to use a transport vehicle to pour asphalt onto the road to be repaired, and then the workers will use tools such as iron rakes to spread the piled asphalt, and then use rolling equipment to roll the spread asphalt to complete the repair of the road.

[0003] The existing technology still has the following shortcomings in the process of repairing:

[0004] 1. In the prior art, asphalt is usually poured onto the road surface to be repaired by a transport vehicle, so the asphalt is easily accumulated, which brings inconvenience to the manual spreading of the asphalt in the later stage and greatly affects the efficiency of road repair.

[0006] 3. After the asphalt is spread, in order to ensure that it remains flat with the road surface after final compaction, it is generally necessary to use tools such as iron rakes to perform preliminary compaction and leveling on the spread asphalt before compaction. However, manual operation is inefficient and extremely time-consuming, and can easily cause the asphalt to dry and harden, affecting the final compaction later.

A storage hopper 3 for placing asphalt is fixed on the top of the mobile vehicle 1, which is used to store asphalt materials required for repair. A discharge barrel 5 is fixed on one side of the mobile vehicle 1, and the discharge barrel 5 is used to put the asphalt in the storage hopper 3 into the pothole to be repaired.

A plurality of spreading plates 18 are provided in the compacting drum 14 to spread the asphalt during rotation to make it more uniform.

[0052] Reference Figure 1 and Figure 2 In addition, two compacting plates 35 are provided under the mobile vehicle 1. The two compacting plates 35 can move up and down alternately to perform preliminary compaction on the spread asphalt, thereby improving the repair efficiency.

[0053] Reference Figure 1-Figure 3 In order to evenly distribute the asphalt into the potholes, the present embodiment also includes a distribution structure. The distribution structure includes a plurality of discharge pipes 4 fixed on one side of the storage hopper 3, and the outer wall of each discharge pipe 4 is provided with a valve for controlling the discharge of asphalt. The bottom ends of the plurality of discharge pipes 4 extend into the discharge barrel 5. A fixed shaft 6 is also fixed in the discharge barrel 5, and a rotating plate 7 located below the discharge pipe 4 is rotatably sleeved on the outer wall of the fixed shaft 6. When the asphalt is discharged from the discharge pipe 4, the rotating plate 7 can lift it up so that the asphalt is more evenly distributed in the potholes. In order to drive the rotating plate 7 to rotate, the present embodiment also fixes a plurality of fixed seats 8 on one side of the discharge barrel 5 close to the compacting barrel 14, and an L-shaped plate 9 is slidably penetrated in each fixed seat 8. The top end of the L-shaped plate 9 can slide and extend into the discharge barrel 5 and cooperate with the bottom of the rotating plate 7. When the spreading plate 18 rotates counterclockwise, it will push the L-shaped plate 9 upward, thereby driving the rotating plate 7 to rotate counterclockwise. In order to prevent the L-shaped plate 9 from being separated from the fixing seat 8 , a limiting plate 10 located above the fixing seat 8 is fixedly sleeved on the outer wall of the L-shaped plate 9 .

[0054] Reference Figure 2 , Figure 3, Figure 4 , Figure 5 and Figure 6 In order to spread the asphalt, the present embodiment also includes a spreading structure. The spreading structure includes a U-shaped frame 11 arranged below the mobile vehicle 1, and the inner walls on both sides of the U-shaped frame 11 are slidably connected with U-shaped plates 12 to improve the stability of the structure. Rotating shafts 15 are fixed at both ends of the compacting cylinder 14 and are rotatably connected to the inner walls on both sides of the U-shaped frame 11. A driving motor 16 is also fixed to one side of the U-shaped frame 11 through a frame, and its output shaft is fixedly connected to one end of one of the rotating shafts 15 through a coupling to drive the compacting cylinder 14 to rotate. A hydraulic groove 21 is provided in the compacting cylinder 14, and a piston plate 22 is sealed and slidably connected in the hydraulic groove 21. A push rod 23 is fixed to the side of the piston plate 22 away from the driving motor 16, and one end of the push rod 23 slides through the compacting cylinder 14 and one side of the U-shaped frame 11 and rotates with a push plate 24. A plurality of guide rods 26 slide through the push plate 24 to limit the push plate 24. A threaded rod 25 is threadedly penetrated in the push plate 24, and one end of the threaded rod 25 is rotatably connected to one side of the U-shaped frame 11. By rotating the threaded rod 25, the push plate 24, the push rod 23 and the piston plate 22 can be driven to move. A plurality of receiving grooves 17 for receiving the spreading plate 18 are provided on the outer wall of the compacting cylinder 14, and the spreading plate 18 is slidably arranged in the receiving grooves 17. A plurality of hydraulic channels 19 connected to the hydraulic groove 21 are provided on the inner walls of the plurality of receiving grooves 17 away from the spreading plate 18. A plurality of piston rods 20 are fixed on the side of the plurality of spreading plates 18 close to the hydraulic groove 21, and one end of the piston rod 20 extends into the hydraulic channel 19 in a sealed sliding manner. When the piston plate 22 moves, the spreading plate 18 can be controlled to extend and retract.

[0055] Reference Figure 2 and Figure 4 The top of the U-shaped frame 11 is rotatably connected to a screw rod 13 through a bearing, and the top thread of the screw rod 13 penetrates the top of the mobile vehicle 1 and extends to the top of the mobile vehicle 1. The top of the screw rod 13 can be connected to a manual turntable or an electric drive device, and the screw rod 13 can be driven to rotate on the mobile vehicle 1 by manually turning the turntable or starting the electric drive device. Since the screw rod 13 is rotatably connected to the top of the U-shaped frame 11, and the top thread of the screw rod 13 penetrates the mobile vehicle 1, when the screw rod 13 rotates, the U-shaped frame 11 will move up and down along the axial direction of the screw rod 13, thereby completing the spreading and final compaction of the asphalt.

[0056] Reference Figure 2 , Figure 7 and Figure 8In order to drive the two compacting plates 35 to move up and down alternately, the present embodiment also includes a reciprocating structure. The reciprocating structure includes a fixed plate 27 fixed to the bottom of the mobile vehicle 1. In the fixed plate 27, two rotating disks 28 are rotatably arranged, and the two rotating disks 28 can rotate synchronously. On both sides of each rotating disk 28, pins 29 are fixed, and these pins 29 are located on the side of the rotating disk 28 that deviates from the center of the circle, and for each rotating disk 28, the two pins 29 thereon are symmetrically placed. Such a design can ensure that when the rotating disk 28 rotates, the pins 29 can generate a driving force for moving up and down.

[0057] Reference Figure 7 and Figure 8 Next, two compaction plates 35 are designed. These two compaction plates 35 are located on both sides of the mobile vehicle 1 and are used to perform preliminary compaction on the spread asphalt. A plurality of connecting cylinders 33 are fixed on the top of each compaction plate 35, and connecting rods 32 are slidably connected in these connecting cylinders 33. The top of the connecting rod 32 is fixedly connected to the bottom of the lifting frame 30, and the lifting frame 30 is located on both sides of the fixed plate 27. In each lifting frame 30, a structure is provided that slides with the pin rod 29 on the rotating disk 28, so that when the rotating disk 28 rotates, the pin rod 29 can drive the lifting frame 30 to move up and down.

[0058] Reference Figure 7 and Fig. 9 In addition, in order to further enhance the movement stability and buffering performance of the compacting plate 35, springs 34 are fixed to the inner walls of the bottoms of the multiple connecting tubes 33. The bottom ends of the multiple connecting rods 32 slide and extend into the corresponding connecting tubes 33, and are fixedly connected to the top ends of the corresponding springs 34. In this way, when the connecting rods 32 drive the compacting plate 35 to move downward, the springs 34 and the connecting tubes 33 cooperate to give way and buffer the movement of the compacting plate 35, thereby improving the compacting effect and the service life of the equipment.

[0059] Reference Figure 2 and Figure 7 In order to limit the up and down movement of the lifting frame 30, a plurality of sliding plates 31 are also provided on the moving vehicle 1, and the top ends of the sliding plates 31 slide through the moving vehicle 1 and are fixedly connected to the top of the lifting frame 30. When the lifting frame 30 moves up and down, the sliding plates 31 will slide in the moving vehicle 1, thereby playing a limiting role.

[0060] Reference Figure 2 , Figure 7 and Figure 8In order to realize the function of the spreading structure driving the reciprocating structure, the present embodiment also includes a transmission structure. In terms of the transmission structure, firstly, a worm 37 is arranged under the mobile vehicle 1, and the worm 37 rotates on one side of the fixed plate 27 through the base. A worm wheel ring 36 is fixed on one side of the two rotating disks 28, and the pin rod 29 is located in the worm wheel ring 36. In this way, when the worm 37 rotates, the two rotating disks 28 can be driven to rotate synchronously through the worm wheel ring 36. A first synchronous wheel 38 is fixed at one end of the worm 37 for cooperating with a synchronous belt.

[0061] Reference Figure 2 , Figure 5 , Figure 8 and Fig.10 At the same time, a rotating column 39 is rotatably connected to one side of the U-shaped plate 12 near the compacting cylinder 14, and a first gear 40 is fixedly sleeved on the outer wall of the rotating column 39. A second gear 42 is fixedly sleeved on the outer wall of the rotating shaft 15 near the driving motor 16, and the second gear 42 is meshed with the first gear 40. In this way, when the rotating shaft 15 rotates, the rotating column 39 can be driven to rotate through the cooperation of the second gear 42 and the first gear 40. A second synchronous wheel 41 is fixed to one end of the rotating column 39, and the second synchronous wheel 41 is connected to the first synchronous wheel 38 through a synchronous belt transmission.

[0062] In actual operation, when the compacting cylinder 14 and the rotating shaft 15 rotate, the rotating shaft 15 will drive the rotating column 39 and the second synchronous wheel 41 to rotate through the cooperation of the second gear 42 and the first gear 40. Then, the second synchronous wheel 41 will drive the worm 37 to rotate through the synchronous belt and the first synchronous wheel 38. The worm 37 then drives the two rotating disks 28 to rotate synchronously through the worm wheel ring 36. Since the pin rod 29 on the rotating disk 28 is slidably matched with the lifting frame 30, when the rotating disk 28 rotates, it can drive the two lifting frames 30 to move up and down alternately. Furthermore, through the cooperation of the connecting rod 32 and the connecting cylinder 33, it is possible to drive the two compacting plates 35 to move up and down alternately to perform preliminary compaction on the spread asphalt.

[0063] By adopting the above structure, this embodiment can realize the rapid repair of the asphalt pavement of the road, improve the repair efficiency and quality. At the same time, the device has a simple structure, convenient operation, and is easy to promote and apply.

[0064] Example 2: Reference Fig.11 and Fig.12, based on the improvement of embodiment 1: a bending plate 43 is slidably connected inside the storage hopper 3. The shape of the bending plate 43 can be designed as needed, and is generally designed to be a bending shape with a high middle and low sides, so as to better push the asphalt. A sliding groove 44 is provided on the inner wall of the bottom of one side of the storage hopper 3, and the bottom of the bending plate 43 slides through the sliding groove 44, so that the bending plate 43 can be smoothly raised and lowered in the storage hopper 3.

[0065] refer to Fig.11 and Fig.12 At the same time, in the lifting mechanism, a plurality of sliding plates 31 are provided on both sides of the lifting frame 30, and the top ends of these sliding plates 31 slide and extend into the storage hopper 3 and touch the bottom of the bending plate 43. When the lifting frame 30 is driven by the driving device to move up and down alternately, the plurality of sliding plates 31 thereon will alternately extend into the storage hopper 3 and intermittently touch the bottom of the bending plate 43, thereby driving the bending plate 43 to move up. In the process of the two lifting frames 30 moving up and down alternately, the bending plate 43 will be intermittently pushed up, thereby pushing the asphalt on the bending plate 43 toward the direction of the discharge pipe 4, which is convenient for the discharge of asphalt.

[0066] A method for repairing an asphalt pavement repair device comprises the following steps:

[0067] S1. After the periphery of the pothole is cut and the inside of the pothole is cleaned, asphalt is put into the storage hopper 3, the mobile vehicle 1 is moved to the pothole by the handrail 45, and the valve on the discharge pipe 4 is opened. The asphalt in the storage hopper 3 falls into the discharge barrel 5 through the discharge pipe 4, and then falls into the pothole through the discharge barrel 5;

[0068] S2. In addition, the push plate 24, the push rod 23 and the piston plate 22 are driven to move by the rotation of the threaded rod 25. The piston plate 22 injects the hydraulic oil into the corresponding hydraulic channel 19, thereby pushing the spreading plate 18 to extend outward, and then pushing the mobile vehicle 1 to move. The compacting cylinder 14 and the plurality of spreading plates 18 are driven to rotate by the driving motor 16. The spreading plate 18 can continuously spread the asphalt accumulated in the potholes on a small scale, and the spread asphalt is relatively flat. In addition, when the compacting cylinder 14 and the spreading plate 18 rotate counterclockwise, the spreading plate 18 pushes the L-shaped plate 9 to move upward, and the L-shaped plate 9 extends into the discharge cylinder 5 and pushes the rotating plate 7 to rotate. The rotating plate 7 can lift the asphalt falling thereon, and then spread the asphalt discharged from the discharge pipe 4, so that the asphalt can be evenly laid inside the potholes, which is convenient for the compacting cylinder 14 and the spreading plate 18 to cooperate in spreading the asphalt in the later stage;

[0069] S3, when the compacting cylinder 14 and the rotating shaft 15 rotate, the rotating shaft 15 drives the rotating column 39 and the second synchronous wheel 41 to rotate through the cooperation of the second gear 42 and the first gear 40, and the second synchronous wheel 41 drives the worm 37 to rotate through the synchronous belt and the first synchronous wheel 38, and the worm 37 drives the two rotating disks 28 to rotate synchronously through the worm wheel ring 36. The cooperation of the pins 29 on both sides of the rotating disk 28 and the lifting frame 30 can drive the two compacting plates 35 to move up and down alternately, and the spread asphalt is preliminarily compacted, so as to judge whether the asphalt put into the pothole has reached the specified amount, and ensure that the asphalt can be relatively flat with the road surface when it is finally compacted in the later stage;

[0070] S4, when the two lifting frames 30 move up and down alternately, the multiple sliding plates 31 on the lifting frames 30 extend alternately into the storage hopper 3 and intermittently drive the bending plate 43 to move upward, so as to push the asphalt on the bending plate 43 toward the discharge pipe 4, so as to facilitate the discharge of the asphalt;

[0071] S5. After the asphalt is placed, spread and preliminarily compacted in the pothole, the threaded rod 25 is rotated in the opposite direction to store the spreading plate 18 into the storage groove 17. The U-shaped frame 11 and the compacting drum 14 are driven downward by the rotation of the screw rod 13 until the compacting drum 14 is flush with the moving wheel 2, and the second gear 42 is disengaged from the first gear 40. Then, the moving vehicle 1 is pushed to move and the compacting drum 14 is driven to rotate by the driving motor 16, and the asphalt is finally compacted by the compacting drum 14.

[0072] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 16 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
