[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Embodiment 1: A road surface detection device for traffic engineering, such as Figure 1-8 As shown, it includes a mobile bracket 1, one end of the mobile bracket 1 is slidably connected to a plurality of detection rods 16, the detection rods 16 can move up and down, when encountering a raised road surface during movement, it will move upward, and when encountering a sunken road surface, it will move downward, one end of the mobile bracket 1 is fixedly connected to a connector 2 30, the other end of the mobile bracket 1 is rotatably connected to a lever 26, one end of the connector 2 30 is fixedly connected to a paint spray port 31, one end of the detection rod 16 is fixedly connected to a lower pressure plate 25, one end of the lower pressure plate 25 is slidably connected to the lever 26, and the lever 2 6, the other end of the connector 30 is rotatably connected with a rope belt 33, one end of the connector 2 30 is fixedly connected with a plurality of paint spraying ports 31, one end of the paint spraying ports 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 clamp 38, one end of the lifting clamp 38 is fixedly connected to the rope belt 33, and one end of the rope belt 33 is movably connected to the guide wheel 39; When the detection rod 16 moves downward for too long, it means that the road surface is too concave and needs to be repaired later. At this time, the paint can be sprayed through the paint spray port 31 for marking. However, because there are not many concave parts on a normal road surface, there are not many places that need to be repaired. After one spraying, it is not necessary to spray again for a long time. In addition, because the road surface is dusty, it is necessary to use a thicker paint to spray a thicker paint surface to prevent rapid wear. Therefore, after spraying once, paint will accumulate at the paint spray port 31. If it is not processed and dried, it will cause the paint to be unable to be sprayed normally. At this time, the sealing plug 34 can be used to 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 downward and needs to be marked, the lever 26 will be rotated through the lower pressure plate 25 on one side. When the lever 26 rotates, the lifting clamping plate 38 will be driven to move through the rope 33 on one side, thereby driving the translation bracket 37 and the sealing plug 34 to rotate. Because the guide rail bracket 35 tracks upward and the lifting clamping plate 38 and the translation bracket 37 can slide with each other, the sealing plug 34 can be moved upward when driving the sealing plug 34 to move without blocking the paint spraying path, and it can automatically reset to block after the paint spraying is completed to prevent drying and solidification. One end of the lifting clamp 38 is fixedly connected to 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 to a spring 2 40, and a sealing boss 41 is fixedly connected inside the sealing plug 34; The guide rod 36 can further prevent the sealing plug 34 from rotating when sliding, and the spring 2 40 can prevent the sealing plug 34 from loosening when moving. The sealing boss 41 is inserted into the paint spray port 31 to further slow down the drying speed.

[0029] In order to solve the problem of supplying air and paint to multiple paint spray ports 31; Figure 1-8 As shown, a paint bucket 6, an air pump 7 and a squeeze switch 27 are fixedly connected to the top of the mobile bracket 1, the air outlet end of the air pump 7 is fixedly connected to the connector 2 30, one end of the paint bucket 6 is fixedly connected to a paint spray pump 28, one end of the paint spray pump 28 is fixedly connected to a connector 1 29, one end of the connector 1 29 is fixedly connected to a plurality of paint supply pipes 32, and one end of the squeeze switch 27 is controlled to be connected to the paint spray pump 28; The paint pump 28 can supply paint to multiple paint spray ports 31 through connector 1 29, and the air pump 7 can spray paint to multiple paint spray ports 31 through connector 2 30. The paint spraying of the air pump 7 can expand the diffusion range of the pigment paint. The squeezing switch 27 is located in the rotation track at one end of the lever 26. Only when the moving distance of the detection rod 16 reaches the preset value will the squeezing switch 27 be triggered to start the paint pump 28 and the air pump 7 to spray paint.

[0030] like Figure 1-8As shown, the lower end of the detection rod 16 is rotatably connected to a detection wheel 18, and the detection rod 16 and one end of the movable bracket 1 are fixedly connected to a spring 17, the detection wheel 18 is a rubber wheel, and the spring 17 can drive the detection rod 16 to squeeze downward for detection.

[0031] like Figure 1-8 As shown, one side of the mobile bracket 1 is rotatably connected to a plurality of mobile wheels 3, one end of the mobile wheel 3 on one side is drivingly connected to a synchronous belt 9, the other end of the 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 spindle 12, one end of the driving spindle 12 is rotatably connected to the mobile bracket 1, one end of the paint bucket 6 is rotatably connected to a stirring shaft 5, and one end of the driving spindle 12 and the stirring shaft 5 is drivingly connected to a synchronous belt 2 10; When the device moves, the stirring shaft 5 can be driven to rotate synchronously by the rotating moving wheel 3, so that the paint pigment in the paint bucket 6 is more uniform; One end of the driving spindle 12 is fixedly connected to a swing rod 21, and a swing driving plate 22 and a swing bracket 19 are slidably connected below the movable bracket 1, one end of the swing driving plate 22 is fixedly connected to the swing bracket 19, one end of the swing rod 21 is movably connected to the inside of the swing driving plate 22, one end of the swing bracket 19 is fixedly connected to a plurality of L-shaped brackets 20, one end of the L-shaped bracket 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 shovel plate 24, and one end of the shovel plate 24 is slidably connected to the detection wheel 18; At the same time, the driving main shaft 12 can drive the swing rod 21 below to rotate, and then slide inside the swing driving plate 22 through the swing rod 21, so that 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 gravel from adhering to the detection wheel 18, affecting normal detection and rolling.

[0032] When the present embodiment is in use, if the detection rod 16 moves downward for too long, it indicates that the road surface is too concave and needs to be repaired later. At this time, the paint can be sprayed through the paint spray port 31 for marking. However, since there are not many concave roads in normal conditions, there are not many places that need to be repaired. After one spraying, it is not necessary to spray again for a long time. Moreover, since the road surface is dusty, it is necessary to use a thicker paint to spray a thicker paint surface to prevent rapid wear. Therefore, after one spraying, paint will accumulate at the paint spray port 31. If it is not processed and dried, it will cause the paint to be unable to be sprayed normally. At this time, the sealing plug 34 can be used to 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 downward and needs to be marked, the lever 26 will be rotated through the lower pressure plate 25 on one side. When the lever 26 rotates, the lifting clamping plate 38 will be driven to move through the rope 33 on one side, thereby driving the translation bracket 37 and the sealing plug 34 to rotate. Because the guide rail bracket 35 tracks upward and the lifting clamping plate 38 and the translation bracket 37 can slide with each other, the sealing plug 34 can be moved upward when driving the sealing plug 34 to move without blocking the paint spraying path, and it can automatically reset to block after the paint spraying is completed to prevent drying and solidification. The guide rod 36 can further prevent the sealing plug 34 from rotating when sliding, and the spring 2 40 can prevent the sealing plug 34 from loosening when moving. The sealing boss 41 is inserted into the paint spray port 31 to further slow down the drying speed; The paint pump 28 can supply paint to multiple paint spray ports 31 through the connector 1 29, and the air pump 7 can spray paint to multiple paint spray ports 31 through the connector 2 30. The paint spraying of the air pump 7 can expand the diffusion range of the pigment paint. The squeeze 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 squeeze switch 27 be triggered to start the paint pump 28 and the air pump 7 to spray paint; When the device moves, the stirring shaft 5 can be driven to rotate synchronously by the rotating moving wheel 3, so that the paint pigment in the paint bucket 6 is more uniform; At the same time, the driving main shaft 12 can drive the swing rod 21 below to rotate, and then slide inside the swing driving plate 22 through the swing rod 21, so that 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 gravel from adhering to the detection wheel 18, affecting normal detection and rolling.

[0033] Embodiment 2: A road surface detection device for traffic engineering, such as Figure 1-8 As shown, one end of the mobile bracket 1 is rotatably connected to a cleaning drive shaft 4 and a plurality of cleaning gears 13, one side of the cleaning gear 13 is fixedly connected to the bottom of the cleaning drive shaft 4, and the plurality of cleaning gears 13 are meshed with each other. The cleaning drive shaft 4 and one end of the driving main shaft 12 are transmission-connected with a synchronous belt 3 11, and a plurality of cleaning stabilizing wheels 14 are rotatably connected to the bottom of the mobile bracket 1, and one end of the cleaning stabilizing wheels 14 and the cleaning gear 13 is transmission-connected with a cleaning brush assembly 15, and the upper end of the cleaning brush assembly 15 is a conveying belt, and the lower end is long bristles; The cleaning drive shaft 4 can drive the cleaning gear 13 to rotate, thereby allowing the cleaning brush assemblies 15 on both sides to rotate synchronously to clean the road surface and reduce the impact of surface dust and gravel on detection.

[0034] One end of the mobile bracket 1 is fixedly connected with a traction plate 2, and the traction plate 2 can be conveniently used for traction and towing operations with other vehicles.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
