Description

Technical Field

[0001] The present invention relates to the technical field of road engineering, and particularly to a pavement detection device for traffic engineering. Background Art

[0002] With the frequent occurrence of traffic accidents and the continuous expansion of urban roads, keeping the roads unobstructed and safe has become one of the important tasks of urban management. In order to accurately evaluate the road conditions, maintain and improve the road quality in a timely manner, pavement detection has become an essential task. Pavement detection includes multiple items such as thickness detection, flatness detection, deflection value detection, and pavement defect detection. The results of pavement detection are of great significance for ensuring traffic safety and maintaining road facilities. Among them, pavement surface defect detection can detect problems such as depressions on the road surface, facilitating timely repair to prevent traffic accidents.

[0003] After retrieval, a patent with the Chinese patent publication number CN118390367A discloses a pavement flatness detection device for construction engineering, including a detection frustum. Multiple horizontal lamp grooves are arranged on the outer side of the top of the detection frustum. A rotating motor is arranged at the center of the top of the detection frustum. A support beam frame is arranged on the top of the rotating motor. An activity extension beam and an upper disc are arranged on the top of the support beam frame. There is a lack of a component for blocking the marking nozzle in the above patent. When spraying viscous paint pigments in relatively dry weather, it is easy to cause the nozzle to be blocked by the dried paint pigments, resulting in the problem that normal spraying and marking cannot be carried out.

[0009] Furthermore, a detection wheel is rotatably connected to the lower end of the detection rod, and a first spring is fixedly connected between the detection rod and one end of the moving bracket.

[0010] As a preferred solution of the present invention, a plurality of moving wheels are rotatably connected to one side of the moving bracket. One end of one side of the moving wheels is drivingly connected to a first synchronous belt. The other end of the first synchronous belt is drivingly connected to a connecting shaft. The other end of the connecting shaft is drivingly connected to a driving main shaft. One end of the driving main shaft is rotatably connected to the moving bracket. One end of the paint bucket is rotatably connected to a stirring shaft. The first synchronous belt and the stirring shaft are drivingly connected by a second synchronous belt at one end.

[0011] As a further solution of the present invention, a swing rod is fixedly connected to one end of the driving main shaft. A swing driving plate and a swing bracket are slidably connected below the moving bracket. One end of the swing driving plate is fixedly connected to the swing bracket. One end of the swing rod is movably connected inside the swing driving plate.

[0012] As a still further solution of the present invention, a plurality of L-shaped brackets are fixedly connected to one end of the swing bracket. One end of the L-shaped brackets is slidably connected to a lifting plate. One end of the lifting plate is slidably connected to the detection rod.

[0020] 4. A road surface detection device for traffic engineering. The swing rod slides inside the swing driving plate, so that the swing bracket and multiple L-shaped brackets swing left and right, driving the shovel plate below to swing left and right to clean the detection wheel, preventing too much dust and gravel from adhering to the detection wheel and affecting normal detection and rolling.

[0021] 5. A road surface detection device for traffic engineering. The cleaning drive shaft can drive the cleaning gear to rotate, and then make the cleaning brush assemblies on both sides rotate synchronously to clean the road surface, reducing the influence of surface dust and gravel on the detection.

[0031] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0032] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.

[0033] Embodiment 1:

[0034] A road surface detection device for traffic engineering, such as Figures 1-8As shown in the figure, it includes a moving bracket 1. One end of the moving bracket 1 is slidably connected with a plurality of detection rods 16. The detection rods 16 can move up and down. When moving, they will move up when encountering a convex road surface and move down when encountering a sunken road surface. One end of the moving bracket 1 is fixedly connected with a connector two 30. The other end of the moving bracket 1 is rotatably connected with a lever 26. One end of the connector two 30 is fixedly connected with a paint spraying port 31. One end of the detection rod 16 is fixedly connected with a lower pressing plate 25. One end of the lower pressing plate 25 is slidably connected to the lever 26. The other end of the lever 26 is rotatably connected with a rope belt 33. One end of the connector two 30 is fixedly connected with a plurality of paint spraying ports 31. One end of the paint spraying port 31 is fixedly connected with a guide rail bracket 35. One end of the guide rail bracket 35 is rotatably connected with a guide wheel 39. The inner side of the guide rail bracket 35 is slidably connected with a translation bracket 37. The lower end of the translation bracket 37 is fixedly connected with a sealing plug 34. The other end of the translation bracket 37 is slidably connected with a lifting clamping plate 38. One end of the lifting clamping plate 38 is fixedly connected to the rope belt 33. The rope belt 33 is movably connected to the guide wheel 39;

[0035] When the detection rod 16 moves down too far, it indicates that the road surface depression is too large and subsequent repair is required. At this time, marking can be carried out by spraying paint through the paint spraying port 31. However, because the normal road surface depression is not much, the positions that need to be repaired are also not many. After spraying paint once, it is not necessary to spray paint again for a long time. And because the road surface dust is large, it is necessary to use a relatively viscous paint to spray a thicker paint surface to prevent rapid wear. Therefore, after spraying paint once, the paint spraying port 31 will accumulate paint. If not processed, it will cause abnormal paint spraying after drying;

[0036] At this time, the sealing plug 34 can block one end of the paint spraying port 31 when not spraying paint, which can slow down the drying speed of the paint. When the detection rod 16 moves down and marking is required, the lever 26 will be rotated through the lower pressing plate 25 on one side. When the lever 26 rotates, the lifting clamping plate 38 will be driven to move through the rope belt 33 on one side, and then drive the translation bracket 37 and the sealing plug 34 to rotate. Because the track of the guide rail bracket 35 is upward and the lifting clamping plate 38 and the translation bracket 37 can slide relative to each other, when driving the sealing plug 34 to move, the sealing plug 34 can move upward without blocking the paint spraying path and can automatically reset for blocking after paint spraying to prevent drying and solidification;

[0037] One end of the lifting clamping plate 38 is fixedly connected with a guide rod 36. One end of the guide rod 36 is slidably connected to the guide rail bracket 35. One end of the guide rail bracket 35 and the guide rod 36 is fixedly connected with a spring two 40. The inside of the sealing plug 34 is fixedly connected with a sealing boss 41;

[0038] The guide rod 36 can further prevent the sealing plug 34 from rotating when sliding. At the same time, the spring two 40 can prevent the sealing plug 34 from loosening when moving. The sealing boss 41 is inserted into the paint spraying port 31 to further delay the drying speed.

[0039] To solve the problem of supplying air and paint to multiple paint spraying nozzles 31; as Figures 1-8 shown, a paint bucket 6, an air pump 7 and a squeezing switch 27 are fixedly connected above the moving bracket 1. The air outlet end of the air pump 7 is fixedly connected to a second connector 30. One end of the paint bucket 6 is fixedly connected to a paint spraying pump 28. One end of the paint spraying pump 28 is fixedly connected to a first connector 29. One end of the first connector 29 is fixedly connected to a plurality of paint supply pipes 32. One end of the squeezing switch 27 is controllably connected to the paint spraying pump 28;

[0040] The paint spraying pump 28 can supply paint to multiple paint spraying nozzles 31 through the first connector 29. The air pump 7 can spray paint to multiple paint spraying nozzles 31 through the second connector 30. The paint spraying by the air pump 7 can expand the diffusion range of the paint. The squeezing switch 27 is located in the rotation trajectory of one end of the lever 26. Only when the moving distance of the detection rod 16 reaches a preset value will the squeezing switch 27 be triggered to start the paint spraying pump 28 and the air pump 7 to spray paint.

[0041] As Figures 1-8 shown, a detection wheel 18 is rotatably connected to the lower end of the detection rod 16. A first spring 17 is fixedly connected between the detection rod 16 and one end of the moving bracket 1. The detection wheel 18 is a rubber wheel. The first spring 17 can drive the detection rod 16 to squeeze downward for detection.

[0042] As Figures 1-8 shown, a plurality of moving wheels 3 are rotatably connected to one side of the moving bracket 1. One end of one side of the moving wheels 3 is drivingly connected to a first synchronous belt 9. The other end of the first synchronous belt 9 is drivingly connected to a connecting shaft 8. The other end of the connecting shaft 8 is drivingly connected to a driving main shaft 12. One end of the driving main shaft 12 is rotatably connected to the moving bracket 1. One end of the paint bucket 6 is rotatably connected to a stirring shaft 5. A second synchronous belt 10 is drivingly connected between one end of the driving main shaft 12 and the stirring shaft 5;

[0043] When the device moves, the rotation of the moving wheels 3 can synchronously drive the stirring shaft 5 to rotate, making the paint in the paint bucket 6 more uniform;

[0044] One end of the driving main shaft 12 is fixedly connected to a swinging rod 21. A swinging driving plate 22 and a swinging bracket 19 are slidably connected below the moving bracket 1. One end of the swinging driving plate 22 is fixedly connected to the swinging bracket 19. One end of the swinging rod 21 is movably connected inside the swinging driving plate 22. One end of the swinging bracket 19 is fixedly connected to a plurality of L-shaped brackets 20. One end of the L-shaped brackets 20 is slidably connected to a lifting plate 23. One end of the lifting plate 23 is slidably connected to the detection rod 16. One end of the lifting plate 23 is fixedly connected to a shoveling plate 24. One end of the shoveling plate 24 is slidably connected to the detection wheel 18;

[0045] Meanwhile, the driving spindle 12 can drive the swing rod 21 below to rotate. Then, by the sliding of the swing rod 21 inside the swing driving plate 22, the swing bracket 19 and multiple L-shaped brackets 20 swing left and right, driving the shovel plate 24 below to swing left and right, cleaning the detection wheel 18, and preventing too much dust and grit from adhering to the detection wheel 18, which may affect normal detection and rolling.

[0046] When this embodiment is in use, when the detection rod 16 moves downward too far, it indicates that the road surface depression is too large and subsequent repair is needed. At this time, marking can be carried out by spraying paint through the paint spraying port 31. However, since the normal road surface depression is not much, the positions that need to be repaired are also not many. After spraying paint once, it is not necessary to spray paint again for a long time. And because the road surface dust is large, relatively viscous paint needs to be used to spray a thicker paint surface to prevent rapid wear. Therefore, after spraying paint once, the paint will accumulate at the paint spraying port 31. If not processed, it will cause abnormal paint spraying after drying;

[0047] At this time, the paint spraying port 31 can be blocked at one end by the plug 34 when not spraying paint, which can slow down the paint drying speed. When the detection rod 16 moves downward and marking is needed, the lever 26 will be rotated by the lower pressing plate 25 on one side. When the lever 26 rotates, the lifting clamping plate 38 will be driven to move by the cord 33 on one side, and then the translation bracket 37 and the plug 34 will be driven to rotate. Since the track of the guide rail bracket 35 is upward and the lifting clamping plate 38 and the translation bracket 37 can slide relative to each other, when driving the plug 34 to move, the plug 34 can be moved upward without blocking the paint spraying path and can automatically reset for blocking after paint spraying to prevent drying and solidification;

[0048] The guide rod 36 can further prevent the plug 34 from rotating when sliding. At the same time, the second spring 40 can prevent the plug 34 from loosening when moving. The plug boss 41 is inserted into the paint spraying port 31 to further delay the drying speed;

[0049] The paint spraying pump 28 can supply paint to multiple paint spraying ports 31 through the connector one 29. The air pump 7 can spray paint to multiple paint spraying ports 31 through the connector two 30. Spraying paint by the air pump 7 can expand the diffusion range of the pigment paint. The extrusion switch 27 is located in the rotation track of one end of the lever 26. Only when the moving distance of the detection rod 16 reaches the preset value will the extrusion switch 27 be triggered to start the paint spraying pump 28 and the air pump 7 to spray paint;

[0050] When the device moves, the stirring shaft 5 can be driven to rotate synchronously by the rotating moving wheel 3, making the paint pigment in the paint bucket 6 more uniform;

[0051] Meanwhile, the driving main shaft 12 can drive the swing rod 21 below to rotate. Then, by sliding the swing rod 21 inside the swing driving plate 22, the swing bracket 19 and multiple L-shaped brackets 20 swing left and right, driving the shovel plate 24 below to swing left and right, cleaning the detection wheel 18, and preventing too much dust and grit from adhering to the detection wheel 18, which may affect normal detection and rolling.

[0052] Embodiment 2:

[0053] A pavement detection device for traffic engineering, as Figures 1-8 shown. One end of the moving bracket 1 is rotatably connected with a cleaning drive shaft 4 and multiple cleaning gears 13. One side cleaning gear 13 is fixedly connected below the cleaning drive shaft 4. The multiple cleaning gears 13 are meshed with each other. One end of the cleaning drive shaft 4 and the driving main shaft 12 are connected by a third synchronous belt 11. Multiple cleaning stabilizing wheels 14 are rotatably connected below the moving bracket 1. One end of the cleaning stabilizing wheels 14 and the cleaning gears 13 are connected by a cleaning brush assembly 15. The upper end of the cleaning brush assembly 15 is a conveyor belt, and the lower end is long bristles;

[0054] The cleaning drive shaft 4 can drive the cleaning gears 13 to rotate, and then synchronously rotate the cleaning brush assemblies 15 on both sides to clean the road surface, reducing the influence of surface dust and grit on detection.

[0055] One end of the moving bracket 1 is fixedly connected with a traction plate 2, which can facilitate the traction and towing operation by other vehicles.

[0056] The above is the preferred specific embodiment of the present invention. The protection scope of the present invention is not limited thereto. Any modification, equivalent replacement, and improvement made by those skilled in the art within the technical scope disclosed by the present invention in combination with the prior art or common knowledge, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
