Description

Technical Field

[0001] The present invention relates to the technical field of road repair, in particular to a road pothole repair device. Background Art

[0002] A road pothole repair device is a mechanical device or tool combination used to quickly repair potholes, cracks and other road damage problems. Its core function is to achieve efficient repair of road surface defects through automated or semi-automated operation processes, thereby improving road traffic quality and service life.

[0003] When repairing the road surface, the staff first use chalk or a spring line to mark the cutting range (expand 3-5cm along the edge of the pothole to remove loose edges); then use a handheld cutting machine to cut along the marked line, and control the depth to the full thickness of the surface layer (for example, if the asphalt surface layer is 8cm thick, the cutting depth is 8cm). If the base layer is damaged, it is necessary to cut to the top surface of the base layer; then use a shovel to remove the loose materials in the pit and a broom to sweep away the residue; after cleaning the pothole, evenly apply emulsified asphalt on the bottom and side walls of the pothole, using a dosage of about 0.3-0.5L / ㎡, to enhance the adhesion between new and old materials; finally fill with asphalt mixture and compact it with a roller.

[0004] However, if the base layer under the pothole is loose (such as the cement stabilized layer is broken), the surrounding structure may be damaged during cutting, resulting in edge fragmentation and disintegration, forming irregular gaps. When filling manually, workers usually rely on tools such as shovels and scrapers to spread asphalt mixtures. The amount of material shoveled each time is estimated based on experience, resulting in large differences in filling thickness in different areas and uneven material accumulation. When encountering deep potholes (depth ≥ 50mm), layered filling is required (each layer thickness ≤ 30mm). As the errors of layered filling accumulate, it is easy to cause the final repair surface to be higher than the original road surface, requiring workers to rework and mill to ensure that the repaired road surface is flush with the original road surface, which not only increases maintenance costs but also increases the workload of workers. For this reason, we propose a road pothole repair device. Summary of the Invention

[0019] The present invention has at least the following beneficial effects:

[0020] 1. When the staff pushes the main body of the plate compactor to move in the pit, the repair asphalt in the asphalt storage bin is transferred to the discharge port through the feeding mechanism and falls into the pit under the action of gravity. The control mechanism detects the flatness of the pit edge during movement and adjusts the flow area of the discharge port at the end of the asphalt storage bin according to the flatness of the pit edge, thereby adjusting the amount of repair asphalt paving.

[0021] 2. After laying a layer of repair asphalt in the pothole, the plate compactor body compacts the laid repair asphalt, and then contacts the regulating mechanism with the edge of the pothole to cooperate with the laying of the second layer of repair asphalt. When the plate compactor body moves the compacted repair layer, the compensation mechanism changes the adjustment range of the regulating mechanism according to the surface convexity of the filler layer. When the regulating mechanism is affected by the flatness of the pothole edge, the greater the concave amplitude of the compacted repair layer, the greater the amplitude of the regulating mechanism to adjust the flow area of the discharge port. If the greater the convex amplitude of the compacted repair layer, the smaller the amplitude of the regulating mechanism to adjust the flow area of the discharge port, thereby avoiding the accumulation of errors during filling, resulting in the final repair surface being higher than the original road surface.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1 to 10The present invention provides a technical solution: a road pothole repair device, comprising a plate compactor body 1; an asphalt storage bin 2, the asphalt storage bin 2 being fixed to the surface of the plate compactor body 1, the outer side of the asphalt storage bin 2 being connected to a docking pipe 20, the inner wall of the asphalt storage bin 2 being provided with a plurality of discharge ports 21, and the plurality of discharge ports 21 being arranged in a line; a feeding mechanism 3, the feeding mechanism 3 being located on the inner wall of the discharge port 21, the feeding mechanism 3 guiding the asphalt in the asphalt storage bin 2 into the discharge port 21; a regulating mechanism 4, two regulating mechanisms 4 being provided, the two regulating mechanisms 4 being respectively located on the inner walls of the discharge ports 21 at both ends of the asphalt storage bin 2, the regulating mechanism 4 detecting the flatness of the pothole edge and adjusting the flow area of the discharge port 21 at the end of the asphalt storage bin 2 according to the flatness of the pothole edge; a compensation mechanism 5, the compensation mechanism 5 being connected to the regulating mechanism 4, and when the plate compactor body 1 drives the compensation mechanism 5 to move on the surface of the filler layer, the compensation mechanism 5 changes the adjustment amplitude of the regulating mechanism 4 according to the unevenness of the filler layer surface.

[0036] When laying repair asphalt in the pit, the pulley on the surface of the plate rammer body 1 is lowered to facilitate the staff to push the plate rammer body 1 to move in the pit. Then the staff puts the side of the plate rammer body 1 close to the edge of the pit, so that the control mechanism 4 on one side of the plate rammer body 1 contacts the edge of the pit, and connects with the external repair asphalt supply equipment through the docking pipe 20. The repair asphalt supply equipment is a key equipment for road repair, which is mainly used for storing, heating and stirring asphalt mixture. In this application, the heated asphalt is transported to the asphalt storage bin 2 and the asphalt is delivered through the outlet. The material port 21 lays the asphalt in the pit, and the external repair asphalt supply equipment inputs the repair asphalt into the asphalt storage bin 2. When the staff pushes the plate compactor body 1 to move in the pit, the repair asphalt in the asphalt storage bin 2 is transferred to the discharge port 21 through the feeding mechanism 3. The asphalt falls into the pit under the action of gravity. The control mechanism 4 detects the flatness of the pit edge when moving, and adjusts the flow area of the discharge port 21 at the end of the asphalt storage bin 2 according to the flatness of the pit edge, thereby adjusting the amount of repair asphalt paving. The staff does not need to judge the amount of shoveling each time based on experience, thereby reducing the workload of the staff.

[0037] After laying a layer of repair asphalt in the pit, the worker reversely extracts the repair asphalt remaining in the asphalt storage bin 2 through the repair asphalt supply equipment, and then separates the repair asphalt supply equipment from the docking pipe 20. The worker retracts the pulley of the plate compactor body 1, and then starts the plate compactor body 1. The plate compactor body 1 works to compact the laid repair asphalt, and the vibration generated when the plate compactor body 1 works shakes the residual repair asphalt in the asphalt storage bin 2 to prevent the repair asphalt from solidifying in the asphalt storage bin 2. After the compaction work of the plate compactor body 1 is completed, the external repair asphalt supply equipment is reconnected to the docking pipe 20. The pipe 20 is docked, and then the regulating mechanism 4 is brought into contact with the edge of the pothole to cooperate with the laying of the second layer of repair asphalt. When the plate rammer body 1 moves the compacted repair layer, the compensation mechanism 5 changes the adjustment amplitude of the regulating mechanism 4 according to the unevenness of the filling layer surface, so that the regulating mechanism 4 is affected by the flatness of the pothole edge. If the compacted repair layer is concave, the regulating mechanism 4 adjusts the flow area of the discharge port 21 to a greater extent. If the compacted repair layer is convex, the regulating mechanism 4 adjusts the flow area of the discharge port 21 to a smaller extent, thereby avoiding the accumulation of errors during filling that result in the final repair surface being higher than the original road surface.

[0038] The feeding mechanism 3 includes multiple screws 30, which are respectively located on the inner walls of multiple discharge ports 21. The rotating shafts of the screws 30 pass through the asphalt storage bin 2 and are fixedly connected to a transmission gear 31. The screws 30 are rotatably connected to the inner wall of the asphalt storage bin 2. A toothed belt 32 is engaged with the outer sides of the multiple transmission gears 31. A servo motor 33 is installed on the surface of the asphalt storage bin 2, and the output shaft of the servo motor 33 is fixed to the axis of a transmission gear 31.

[0039] When the feeding mechanism 3 is working, the servo motor 33 drives the transmission gear 31 fixedly connected to its output shaft to rotate, and the transmission gear 31 drives the outer toothed belt 32 to rotate, so that multiple transmission gears 31 rotate synchronously, and the transmission gear 31 drives the screw 30 to rotate. Since the screw 30 is located in the discharge port 21, the screw 30 guides the repair asphalt in the asphalt storage bin 2 to the discharge port 21 when it rotates, and finally falls into the pit from the discharge port 21. Before use, the staff adjusts the speed of the servo motor 33 according to the paving thickness, thereby adjusting the feeding speed of the screw 30.

[0040] The regulating mechanism 4 includes a baffle 40 that is slidingly connected to the inner wall of the discharge port 21, an adjusting block 41 is fixedly connected to the outside of the baffle 40, a transmission screw 42 is rotatably connected to the inner wall of the asphalt storage bin 2, the adjusting block 41 is threadedly connected to the surface of the transmission screw 42, and a transmission part 43 is provided at the end of the transmission screw 42 to drive the transmission screw 42 to rotate. A detection part 44 for detecting the flatness of the edge of the pit is provided on the outside of the asphalt storage bin 2, and the detection part 44 is connected to the transmission part 43.

[0041] When the plate compactor body 1 moves in the pit, the detection part 44 abutting against the edge of the pit will detect the flatness of the edge of the pit in real time. When the edge of the pit is raised, the detection part 44 controls the transmission part 43 to work, and the transmission part 43 drives the transmission screw 42 to rotate counterclockwise. The transmission screw 42 rotates counterclockwise to drive the adjustment block 41 to move on the surface of the transmission screw 42, so that the adjustment block 41 drives the baffle 40 to slide on the inner wall of the discharge port 21, so that the baffle 40 reduces the flow area of the discharge port 21.

[0042] When the edge of the groove is concave, the detection part 44 controls the transmission part 43 to work, and the transmission part 43 drives the transmission screw 42 to rotate clockwise. The clockwise rotation of the transmission screw 42 drives the adjustment block 41 to move on the surface of the transmission screw 42, so that the adjustment block 41 drives the baffle 40 to slide on the inner wall of the discharge port 21, so that the baffle 40 increases the flow area of the discharge port 21.

[0043] The detection part 44 includes a sliding rod 45 that is slidably connected to the inner wall of the asphalt storage bin 2. The end of the sliding rod 45 is fixedly connected to a compression spring 46. The compression spring 46 is fixed to the inner wall of the asphalt storage bin 2. The outer side of the sliding rod 45 is fixedly connected to a connecting plate 47. The outer side of the connecting plate 47 is fixedly connected to a probe 48.

[0044] When the plate compactor body 1 moves in the pit, the compression spring 46 in the compressed state causes the probe 48 to rest against the edge of the pit. If the pit edge is raised, the pit edge and the probe 48 squeeze each other, causing the probe 48 to push the connecting plate 47 to move. The connecting plate 47 pushes the sliding rod 45 to slide on the inner wall of the asphalt storage bin 2, and the sliding rod 45 squeezes the compression spring 46 again.

[0045] If it moves to the concave part of the pit surface, the compression spring 46 in the compressed state pushes the sliding rod 45 to slide outward, the sliding rod 45 pushes the connecting plate 47 to move, and the connecting plate 47 drives the probe 48 to move, so that the probe 48 moves to the bottom of the pit concave part. As the plate compactor body 1 moves, the probe 48 moves according to the degree of concavity of the inner wall of the pit, thereby detecting the degree of concavity of the pit edge.

[0046] The transmission member 43 includes a connecting frame 49 fixedly connected to the sliding rod 45, and the connecting frame 49 is fixedly connected to a tooth plate 410 at one end away from the sliding rod 45. The outer side of the tooth plate 410 is meshed with a transmission gear 2 411, and the transmission gear 2 411 is rotatably connected to the inner wall of the asphalt storage bin 2. The compensation mechanism 5 is connected to the transmission gear 2 411, and the outer side of the transmission screw 42 is fixedly connected to the transmission gear 3 412, and the outer side of the transmission gear 3 412 is meshed with a transmission belt 413. The transmission belt 413 is made of rubber material so that it can transmit deformation. A toothed groove 414 is provided on the inner side of the transmission belt 413, and the compensation mechanism 5 is connected to the transmission belt 413.

[0047] When the edge of the groove is recessed, the compression spring 46 pushes the sliding rod 45 to slide outward, the sliding rod 45 drives the connecting frame 49 to move outward, the connecting frame 49 drives the tooth plate 410 to slide outward, the tooth plate 410 drives the transmission gear 2 411 to rotate clockwise, the transmission gear 2 411 drives the transmission belt 413 to rotate clockwise through the compensation mechanism 5, the transmission belt 413 drives the transmission gear 3 412 to rotate clockwise, the transmission gear 3 412 drives the transmission screw 42 to rotate clockwise, the transmission screw 42 rotates clockwise and drives the adjustment block 41 to move on the surface of the transmission screw 42, so that the adjustment block 41 drives the baffle 40 to slide on the inner wall of the discharge port 21, so that the baffle 40 increases the flow area of the discharge port 21.

[0048] When moving to the raised position at the edge of the pit, the sliding rod 45 slides along the inner wall of the asphalt storage bin 2 and squeezes the compression spring 46. The sliding rod 45 drives the connecting frame 49 to move inward, and the connecting frame 49 drives the tooth plate 410 to move. The tooth plate 410 drives the transmission gear 2 411 to rotate counterclockwise. The transmission gear 2 411 drives the transmission belt 413 to rotate counterclockwise through the compensation mechanism 5. The transmission belt 413 drives the transmission gear 3 412 to rotate counterclockwise. The transmission gear 3 412 drives the transmission screw 42 to rotate counterclockwise. The transmission screw 42 rotates counterclockwise and drives the adjustment block 41 to move on the surface of the transmission screw 42, so that the adjustment block 41 drives the baffle 40 to slide on the inner wall of the discharge port 21, so that the baffle 40 reduces the flow area of the discharge port 21.

[0049] The compensation mechanism 5 includes a transmission cylinder 50 fixedly connected to the second transmission gear 411. The transmission cylinder 50 rotates coaxially with the second transmission gear 411. The transmission cylinder 50 is located inside the transmission belt 413. The inner wall of the transmission cylinder 50 is provided with a connecting piece 51 connected to the transmission belt 413. The inner wall of the connecting plate 47 is provided with a compensation piece 52 for adjusting the size of the connecting piece 51.

[0050] The compensating member 52 includes a contact 53 that is slidably connected to the inner wall of the connecting plate 47. A connecting pipe 54 is connected between the connecting plate 47 and the asphalt storage bin 2. A plurality of balls 55 are provided on the inner wall of the connecting pipe 54. The contact 53 abuts against the balls 55. Due to the sliding cooperation between the balls 55 and the connecting pipe 54, the contact 53 can slide on the inner wall of the connecting plate 47, thereby providing real-time feedback on the depth of the recess. A conical column 56 is slidably connected to the inner wall of the transmission cylinder 50. The arc surface of the conical column 56 contacts the adjusting rod 510. The end of the conical column 56 is rotatably connected to the push rod 57. The push rod 57 passes through the inner wall of the transmission cylinder 50 and is fixedly connected to a transmission plate 58. The cross-section of the transmission plate 58 is T-shaped and is slidably connected to the inner wall of the asphalt storage bin 2. The transmission plate 58 abuts against the balls 55. A return spring 59 is provided on the outside of the push rod 57. The two ends of the return spring 59 are respectively fixed to the transmission plate 58 and the asphalt storage bin 2. The return spring 59 is in a compressed state, providing outward thrust.

[0051] The connecting member 51 includes an adjusting rod 510 that is slidably connected to the inner wall of the transmission cylinder 50. There are multiple adjusting rods 510 that are evenly distributed on the surface of the transmission cylinder 50. The adjusting rod 510 is provided with a bevel end near the conical column 56. The end of the adjusting rod 510 that passes through the transmission cylinder 50 is fixedly connected to a friction plate 511.

[0052] When the plate compactor body 1 moves on the repair layer after compaction, the compensation member 52 contacts the surface of the repair layer. If the compacted repair layer is concave, the return spring 59 in the compressed state pushes the transmission plate 58 to move outward, and the push rod 57 pushes the ball 55 to roll on the inner wall of the connecting tube 54, so that the ball 55 squeezes the contact 53 to move outward until the contact 53 moves to the bottom of the concave repair layer, and the transmission plate 58 drives the push rod 57 to move outward, and the push rod 57 is rotatably connected to the tapered column 56 through the bearing, so that when the push rod 57 moves, the push rod 57 drives the tapered column 56 to move, and the tapered column 56 squeezes the adjusting rod 510, so that multiple adjusting rods 510 slide outward, and the adjusting rod 510 drives the friction plate 511 to move, and multiple friction plates 511 The two gears 412 move simultaneously to prop up the transmission belt 413. At this time, the transmission ratio changes, so that when the transmission cylinder 50 rotates the same angle, the number of rotations of the transmission gear three 412 increases, so that the number of rotations of the transmission screw 42 driven by the transmission gear three 412 increases, which increases the moving distance of the adjustment block 41. Therefore, when the probe 48 moves the same distance, the greater the movement amplitude of the baffle 40 on the inner wall of the discharge port 21, that is, when encountering a convex edge of the pothole, the amount of repair asphalt released by the discharge port 21 will be less, and when encountering a concave edge of the pothole, the amount of repair asphalt released by the discharge port 21 will be more, thereby increasing the compensation amount for this layer of filling layer to avoid the final repair surface being higher than the original road surface, and the greater the concave amplitude, the greater the outward expansion amplitude of the multiple friction plates 511.

[0053] Similarly, if the repair layer passed by the contact 53 is raised, the transmission plate 58 squeezes the return spring 59, so that the push rod 57 drives the conical column 56 to move, so that the arc surface of the conical column 56 no longer squeezes the adjusting rod 510. At this time, the transmission belt 413 in the tensioned state squeezes the friction plate 511, and the friction plate 511 drives the adjusting rod 510 to abut against the arc surface of the conical column 56 again. At this time, when the transmission cylinder 50 rotates by the same angle, the number of rotations of the transmission gear three 412 is reduced, so that the moving distance of the adjusting block 41 is reduced, so that when the probe 48 moves the same distance, the movement amplitude of the baffle 40 on the inner wall of the discharge port 21 is reduced, that is, when the edge of the pothole is raised or recessed, the repair asphalt released by the discharge port 21 will be less than the amount released when the repair layer is flat, thereby avoiding the final repair surface being higher than the original road surface.

[0054] Example 2

[0055] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the width of the friction plate 511 is wider than the transmission belt 413, and strip grooves are provided on the surface of the friction plate 511, thereby increasing the friction between the friction plate 511 and the transmission belt 413 and improving the transmission stability.
