Description

Technical Field

[0001] The present invention relates to the technical field of pavement crack repairing, and in particular to a pavement crack repairing device used in traffic engineering. Background Art

[0002] Currently, there are many types of caulking equipment, including manual and automatic. Using equipment to automatically repair road cracks can greatly reduce labor intensity. However, existing crack repair equipment has the following disadvantages: first, the asphalt at the asphalt outlet of the equipment is easy to coagulate; second, for deeper cracks, the asphalt injected into the cracks will become hollow.

[0003] Chinese patent CN117966570B discloses a road crack repair device for traffic engineering construction, comprising: a caulking portion for filling asphalt into the cracks, the caulking portion comprising a main pipe, the main pipe being fixedly connected to two branch pipes, and the two branch pipes being rotatably mounted with a first caulking dish and a second caulking dish respectively; a vibrating portion for vibrating the asphalt filled in the cracks, the vibrating portion comprising a support plate fixedly mounted on the bottom of the main pipe via a support rod, a plurality of sliding rods being slidably mounted on the support plate, a vibrating plate being fixedly mounted on the plurality of sliding rods, a limiting plate being fixedly mounted on each of the sliding rods and cooperating with the support plate, a vibrating mechanism being mounted between the vibrating plate and the support plate; two rotating shafts 1 being rotatably mounted on the support plate, two rollers being fixedly mounted on each of the two rotating shafts 1, a plurality of vibrating cones being mounted at the bottom of the vibrating plate, and a branch mechanism being mounted between each vibrating cone and the vibrating plate, and a dredging mechanism being mounted between the two rollers located on the same rotating shaft 1 and the corresponding first caulking dish and the second caulking dish.

[0004] The above solution uses vibrating cones to ensure that the asphalt flowing into the cracks is more evenly distributed, thus avoiding hollowing in the cracks. However, the vibrating cones in this solution are arranged very closely together, making them difficult to manufacture. The cone-shaped heads of the vibrating cones can easily cause significant damage to the road surface during vibration. Furthermore, the compacting cylinders are too small and too numerous, making them easily stuck with stones during actual use, leading to damage. This results in high manufacturing and operating costs. Existing vibrating cones are placed directly on the vehicle body, causing the reaction force of the vibration to act on the vehicle body during vibration, shortening the vehicle body's lifespan.

[0015] Preferably, a fan is provided at the front end of the vibrating group, and the fan blows air onto the ground at the front end of the vibrating group.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the vehicle body moves to the location of a crack in the road surface, a camera installed at the bottom of the vehicle body locates the crack in the ground through the camera. The vehicle body is then moved so that the injection head can move directly above the crack, and finally the injection head discharges asphalt. As the injection head discharges asphalt, the vibration unit starts to work. At this time, the connecting rod rotates and lowers the vibration roller, making the vibration roller contact the ground. At this time, the angle between the extension direction of the connecting rod and the length direction of the vehicle body is less than 90 degrees. In this way, when the vibration roller vibrates, the connecting rod can swing back and forth slightly around the hinge between itself and the vehicle body, reducing the impact of the vibration roller on the vehicle body during vibration and extending the life of the vehicle body.

[0018] 2. During vibration, the first rotary driver drives the rotating shaft to rotate. Since a protrusion is fixedly provided on the peripheral wall of the rotating shaft, the protrusion rotates around the axis of the rotating shaft, so that the dynamic balance of the rotating shaft during rotation is sharply reduced. Under the action of the elastic component, the vibration roller can produce a vibration effect on the ground when the rotating shaft rotates. At the same time, since the vibration roller and the ground roll in cooperation, the vibration roller can always fit the ground when vibrating the ground, and will not scratch the ground, thereby achieving the effect of vibrating the ground without causing damage to the ground.

[0019] 3. By setting three vibration units at the bottom of the vehicle body, the three vibration units are arranged in a triangle. When the vehicle body moves forward, the three vibration units at the bottom of the vehicle body move with the vehicle body. When the injection head starts to discharge asphalt, the two vibration units that constitute the vibration group of the three vibration units are located on both sides of the crack, while the vibration unit corresponding to the smoothing group at the rear end is located directly above the crack. In the process of the injection head injecting asphalt into the crack, the camera monitors the asphalt injection situation on the crack. If the asphalt injected into the crack no longer flows into the crack, it means that the crack is filled. At this time, the vehicle body starts to move along the extension direction of the crack, and the filled crack is rolled over by the vibration unit at the rear end, so that the asphalt filling the crack can be flattened, avoiding the accumulation of asphalt used for filling in the crack.

[0035] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figure 1 、 Figure 2 and Figure 5-Figure 7: A road surface gap repair device for traffic engineering, comprising a vehicle body 1 and an injection head 11 arranged on the vehicle body 1, a vibration unit 2 for vibrating the ground is arranged at the lower part of the vehicle body 1; the vibration unit 2 includes a connecting rod 22 hinged at one end to the lower part of the vehicle body 1, a vibration roller 21 is arranged at the end of the connecting rod 22 away from the vehicle body 1 and rotated along the width direction of the vehicle body 1, the vibration roller 21 is a cylindrical cavity structure, a rotating shaft 23 is arranged in the vibration roller 21 and rotates along the axis of the vibration roller 21, a protrusion 24 is fixedly arranged on the peripheral wall of the rotating shaft 23, and a driving mechanism for driving the rotating shaft 23 to rotate is provided on the connecting rod 22 The first rotating driver 25 is movable, and an elastic component 26 is arranged between the rotating shaft 23 and the vibration roller 21. The vibration unit 2 has an operating mode and a non-operating mode, and in both modes, the angle between the extension direction of the connecting rod 22 and the length direction of the vehicle body 1 is always less than 90 degrees. In the operating mode, the vibration roller 21 arranged at the end of the connecting rod 22 contacts the ground and rolls together. In the non-operating mode, the vibration roller 21 arranged at the end of the connecting rod 22 contacts the bottom of the vehicle body 1, and neither the vibration roller 21 nor the rotating shaft 23 rotates, and the angle between the extension direction of the connecting rod 22 and the length direction of the vehicle body 1 is minimum.

[0037] Wheels 12 are provided at the bottom of the vehicle body 1, and the vehicle body 1 moves on the road surface through the wheels 12, and the wheels 12 have a steering system. Since this article does not optimize the steering system of the wheels 12 and the steering system of the wheels 12 is existing technology, the steering system is simplified in the accompanying drawings and will not be repeated in the specification. The injection head 11 provided on the vehicle body 1 is used to inject asphalt into the cracks in the road surface. In a conventional road surface crack repair device, when the crack is deep, the asphalt flowing into the crack through the injection head 11 blocks the air in the crack, which in turn causes the air in the crack to block the asphalt from flowing into the crack. This will cause hollowing in the crack, causing the external road surface to appear filled, but the actual crack is still hollow. The filled crack will soon be damaged again in subsequent use. In order to avoid the above situation, a vibrating hammer is provided at the bottom of the vehicle body 1 in the prior art. When the injection head 11 injects asphalt into the crack, the vibrating hammer vibrates the ground around the crack to ensure that the air in the crack can be vibrated out and the asphalt can be evenly filled in the crack. However, the vibrating hammer will directly impact the ground during vibration, that is, the vibrating hammer hits the ground by itself to produce a vibration effect, which can easily cause further damage to the ground. At the same time, the reaction force of the vibration will also act on the vehicle body 1, reducing the service life of the vehicle body 1.

[0038] In order to avoid the above situation, the vibration unit 2 is redesigned so that the vibration unit 2 will not cause damage to the ground when vibrating the ground. The structure and specific working process of the vibration unit 2 are as follows:

[0039] During normal vehicle movement, the vibration unit 2 is in a non-operating mode. The connecting rod 22 is raised, meaning the vibration roller 21 at the end of the connecting rod 22 is in contact with the bottom of the vehicle body 1. The angle between the extension of the connecting rod 22 and the extension of the vehicle body 1 is minimized. When the vehicle body 1 reaches a crack in the road surface, a camera 13 located at the bottom of the vehicle body 1 locates the crack. The vehicle body 1 is then moved so that the injection head 11 is positioned directly above the crack, allowing the injection head 11 to discharge the asphalt. When the injection head 11 discharges asphalt, the vibration unit 2 starts to start. At this time, the connecting rod 22 rotates and lowers the vibration roller 21, so that the vibration roller 21 contacts the ground. At this time, the angle between the extension direction of the connecting rod 22 and the length direction of the vehicle body 1 is greater than the angle when the vibration unit 2 is in the non-operating mode, but the angle is still less than 90 degrees. In this way, when the vibration roller 21 vibrates, the connecting rod 22 can swing back and forth slightly around the hinge between itself and the vehicle body 1, reducing the impact of the vibration roller 21 on the vehicle body 1 during vibration and extending the life of the vehicle body 1.

[0040] During vibration, the first rotary driver 25 is in operation. The first rotary driver 25 is preferably a servo motor. The first rotary driver 25 drives the rotating shaft 23 to rotate. Since a protrusion 24 is fixedly provided on the peripheral wall of the rotating shaft 23, the protrusion 24 rotates around the axis of the rotating shaft 23, so that the dynamic balance of the rotating shaft 23 during rotation is sharply reduced. Under the action of the elastic component 26, the vibration roller 21 can produce a vibration effect on the ground when the rotating shaft 23 rotates. At the same time, since the vibration roller 21 rolls with the ground, the vibration roller 21 can always fit the ground when vibrating the ground, and will not scratch the ground, thereby achieving the effect of vibrating the ground without causing damage to the ground.

[0041] Reference Figure 1-13 : There are three vibration units 2, which are arranged in a triangle. In the forward direction of the vehicle body 1, two of the vibration units 2 are located at the front end of the remaining vibration unit 2. The projection of the injection head 11 in the vertical direction is located in the triangular area formed by the three vibration units 2. The two vibration units 2 at the front end constitute a vibration group, and the vibration unit 2 at the rear end constitutes a smoothing group.

[0042] When the vehicle body 1 moves forward, the three vibration units 2 at the bottom of the vehicle body 1 move together with the vehicle body 1. When the injection head 11 starts to discharge asphalt, the two vibration units 2 constituting the vibration group of the three vibration units 2 are respectively located on both sides of the crack, while the vibration unit corresponding to the smoothing group at the rear end is located directly above the crack. In the process of the injection head 11 injecting asphalt into the crack, the camera 13 monitors the asphalt injection situation on the crack. If the asphalt injected into the crack no longer flows into the crack, it means that the crack is filled. At this time, the vehicle body 1 starts to move along the extension direction of the crack, and the filled crack is rolled over by the vibration unit 2 at the rear end, so that the asphalt filling the crack can be flattened.

[0043] Reference Figure 12 and Figure 13 : A ring 27 is provided in the vibration roller 21, and the axis of the ring 27 is colinear with the axis of the vibration roller 21. The ring 27 is fixedly arranged at the end of the connecting rod 22, and the rotating shaft 23 passes through the inner ring of the ring 27 and rotates with the ring 27. There is an annular gap between the ring 27 and the inner ring side wall of the vibration roller 21, and the elastic component 26 is provided with multiple and evenly distributed in the annular gap around the axis of the annular gap. The elastic component 26 includes a sliding rod 261 with one end hinged to the ring 27, and a sliding sleeve 262 is slidingly sleeved on the sliding rod 261 along the extension direction of the sliding rod 261. The end of the sliding sleeve 262 away from the sliding rod 261 is hinged to the inner ring side wall of the vibration roller 21, and there is a gap between the end of the sliding rod 261 and the bottom of the sliding sleeve 262. A spring 263 is provided in the gap along the extension direction of the sliding rod 261, and the two ends of the spring 263 are respectively fixedly connected to the end of the sliding rod 261 and the bottom of the sliding sleeve.

[0044] In this way, when the rotating shaft 23 rotates, relative sliding can occur between the sliding rod 261 and the sliding sleeve 262, and the spring 263 located in the sliding sleeve 262 can be continuously squeezed. The reaction force of the spring 263 acts on the vibration roller 21, so that the vibration roller 21 can vibrate the ground.

[0045] Reference Figure 7 The vibration roller 21 includes a roller body 213 with a cylindrical structure. A plurality of drag reduction wheels 211 are evenly arranged on the roller body 213 around the axis of the roller body 213. The axis of the drag reduction wheel 211 is parallel to the axis of the roller body 213. A rubber sleeve 212 is provided on the outer rotating sleeve of the roller body 213, and the inner wall of the rubber sleeve 212 is in rolling cooperation with the reduction wheel.

[0046] When the vibration roller 21 contacts the ground, the roller body 213 contacts the ground through the rubber sleeve 212. During the movement of the vehicle body 1, the roller body 213 does not rotate, while the rubber sleeve 212 mounted on the outside of the roller body 213 rotates around the axis of the roller body 213. In this way, the vibration roller 21 achieves rolling cooperation with the ground, and support is provided between the rotating shaft 23 and the vibration roller 21 by the elastic component 26.

[0047] Reference Figure 10 and Figure 11 : A switching unit 3 is provided between the vibrating group and the smoothing group for driving the connecting rods 22 in the vibration units 2 of the two groups to rotate synchronously. The switching unit 3 includes two gears 32. The two gears 32 are respectively provided at the ends of the two corresponding connecting rods 22 in the vibrating group and the smoothing group. There is a gap between the two gears 32. A lifting plate 31 is provided in the gap for movement in the vertical direction. Two sets of meshing teeth are respectively provided on both sides of the lifting plate 31 in the vertical direction. The lifting plate 31 is respectively engaged with the two gears 32 through the two sets of meshing teeth.

[0048] When the lifting plate 31 rises, the gear 32 drives the connecting rod 22 down, and the vibration roller 21 at the end of the connecting rod 22 contacts the ground. When the lifting plate 31 descends, the gear 32 drives the connecting rod 22 up, and the vibration roller 21 at the end of the connecting rod 22 loses contact with the ground. When the angle between the extension direction of the connecting rod 22 and the length direction of the vehicle body 1 reaches the minimum, the vibration roller 21 contacts the bottom of the vehicle body 1. Since the two sides of the lifting plate 31 are respectively engaged with the two gears 32, and it is difficult to ensure that the vibration units 2 corresponding to the vibrating group and the smoothing group are exactly the same during operation, during the vibration process, if the two gears 32 are respectively connected to the vibrating group and the smoothing group, the vibration units 2 in the two groups will affect each other, causing damage to the meshing positions of the two gears 32 and the two sides of the lifting plate 31. In order to avoid the above problems, the above problems will be solved below.

[0049] Reference Figure 9 : A first clutch plate 33 is fixedly provided at the end of the connecting rod 22 in the vibration unit 2 corresponding to the vibrating group and the smoothing group, and a second clutch plate 34 is provided between the first clutch plate 33 and the gear 32 so as to be movable along the width direction of the vehicle body 1. A plurality of extension rods 35 are fixedly provided at the end of the second clutch plate 34 away from the first clutch plate 33 along the width direction of the vehicle body 1, and the extension rods 35 pass through the gear 32.

[0050] When it is necessary to drive the connecting rod 22 to rotate, the second clutch plate 34 moves toward the first clutch plate 33. After the first clutch plate 33 and the second clutch plate 34 contact each other, the gear 32 drives the second clutch plate 34 to rotate through the extension rod 35, thereby rotating the first clutch plate 33, and finally causing the corresponding vibration units 2 in the vibrating group and the smoothing group to rise or fall synchronously. The rising refers to the contact between the vibration roller 21 in the vibration unit 2 and the bottom of the vehicle body 1, and the lowering refers to the contact between the vibration roller 21 in the vibration unit 2 and the ground.

[0051] Reference Figure 9 and Figure 11 : A pushing unit 36 for pushing the extension rod 35 to move is provided at the end of the extension rod 35 away from the second clutch plate 34, and the pushing unit 36 includes a pushing plate 361 fixedly provided at the end of the extension rod 35 away from the second clutch plate 34, and a pushing frame 362 is provided at the end of the pushing plate 361 away from the extension rod 35. The pushing frame 362 moves along the width direction of the vehicle body 1 and the pushing frame 362 rotates with the pushing plate 361. A second rotation driver 363 is horizontally provided on one side of the pushing frame 362, and a first threaded rod 364 is fixedly provided on the output end of the second rotation driver 363. The first threaded rod 364 passes through the pushing frame 362 along the width direction of the vehicle body 1 and is threadedly engaged with the pushing frame 362.

[0052] When the second clutch plate 34 is pushed to move, the second rotary driver 363 is activated. The second rotary driver 363 is preferably a servo motor. The second rotary driver 363 drives the first threaded rod 364 to rotate, causing the push frame 362 to move along the width direction of the vehicle body 1, thereby causing the push plate 361 to move synchronously with the push frame 362. The extension rod 35 fixed to the push plate 361 drives the second clutch plate 34 to move, thereby achieving the drive of the second clutch plate 34. It is worth noting that after the vibration unit 2 contacts the ground, the second clutch plate 34 separates from the first clutch plate 33. In this way, the vibration units 2 corresponding to the tamping group and the smoothing group will not affect each other, avoiding wear between the gear 32 and the lifting plate 31.

[0053] Reference Figure 2 A driving unit 37 is provided on the upper portion of the lifting plate 31 for driving the lifting plate 31 to move in a vertical direction.

[0054] Reference Figure 4: The driving unit 37 includes a lifting frame 371 fixedly arranged on the upper part of the lifting plate 31, and a fixing frame 372 is arranged above the lifting frame 371. The fixing frame 372 is fixedly connected to the vehicle body 1, and a second threaded rod 373 is vertically arranged between the fixing frame 372 and the vehicle body 1. The second threaded rod 373 vertically penetrates the lifting frame 371 and is threadedly engaged with the lifting frame 371. A third rotation driver 374 is vertically arranged on the fixing frame 372. The third rotation driver 374 is used to drive the second threaded rod 373 to rotate. A guide rod 375 is also vertically arranged between the fixing frame 372 and the vehicle body 1. The two ends of the guide rod 375 are respectively fixedly connected to the fixing frame 372 and the vehicle body 1, and the guide rod 375 vertically penetrates the lifting frame 371 and is slidably engaged with the lifting frame 371.

[0055] The third rotation driver 374 is preferably a servo motor. When the third rotation driver 374 is started, the third rotation driver 374 drives the second threaded rod 373 to rotate. Under the restriction of the guide rod 375, the lifting frame 371 is lifted and lowered in the vertical direction, thereby causing the lifting plate 31 to be lifted and lowered in the vertical direction.

[0056] Reference Figure 1 and Figure 2 : A fan 4 is provided at the front end of the vibrating group, and the fan 4 blows the air flow to the ground at the front end of the vibrating group.

[0057] Thereby realize cleaning the crack position to be filled, and avoid asphalt from mixing with more stones or dust when filling. A storage box 5 for storing asphalt is also provided on the top of the vehicle body 1, and the injection head 11 draws asphalt from the storage box 5 and discharges it to the ground.

[0058] Working Principle: Before the vehicle body 1 reaches the crack, the vibration unit 2 is in a non-operating mode. The connecting rod 22 is raised, meaning the vibration roller 21 at the end of the connecting rod 22 is in contact with the bottom of the vehicle body 1. The angle between the extension direction of the connecting rod 22 and the extension direction of the vehicle body 1 is minimal. When the vehicle body 1 reaches the side of the crack, it advances in the crack's direction, and the three vibration units 2 at the bottom of the vehicle body 1 move with it. When the injection head 11 begins to discharge asphalt, the two vibration units 2 that make up the tamping group are positioned on either side of the crack, while the corresponding vibration unit in the rear-end smoothing group is positioned directly above the crack. As the injection head 11 injects asphalt into the crack, the camera 13 monitors the asphalt injection status. If the asphalt injected into the crack no longer flows into the crack, the crack is filled. The vehicle body 1 then begins to move in the crack's direction, and the vibration unit 2 at the rear end rolls over the filled crack, flattening the asphalt that filled the crack.
