Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection, and specifically relates to an instrument for detecting the flatness of urban road surfaces during acceptance Background Technique

[0002] Flatness, as a core evaluation index for road construction quality, is evaluated by intermittently or continuously measuring the unevenness of the road surface through a standard gauge. This index is closely related to the flatness state of each structural layer of the road surface, and the slight unevenness of each layer will eventually accumulate and be reflected on the road surface layer. Road unevenness not only directly increases the driving resistance, but also causes vehicle vibrations, resulting in driving bumps, affecting speed, driving smoothness and passenger comfort. In addition, the vibration impact aggravates the two-way wear of the vehicle and the road, and even promotes the formation of water accumulation, accelerating the deterioration of the road surface.

[0003] Chinese Patent CN212925695U discloses an instrument for detecting the flatness of urban road surfaces during acceptance, including a bottom plate. Rollers are installed at the four corners of the bottom surface of the bottom plate. A handrail is arranged at the front end of the bottom plate. A driving roller and a driven roller are vertically installed on both sides of the bottom plate through bearings respectively. A vertical plate is arranged vertically in the middle of the bottom plate. The bottom end of the driving roller extends below the bottom plate and is connected to the rotating shaft of one of the rollers through bevel gears. For this instrument for detecting the flatness of urban road surfaces during acceptance, by pushing the bottom plate to move, the driving roller can be driven to rotate synchronously, thereby realizing that the roll paper wound around the driven roller passes through the front of the vertical plate and then winds around the driving roller. As the driving roller rotates, the roll paper moves to the right along the front of the vertical plate. During this process, the rollers are in contact with the road surface and rise and fall with the road surface. Finally, the shape of the road surface is drawn on the roll paper through a surveying and mapping component, and then the flatness can be measured from the lines on the roll paper. This method is simple to operate and the drawing is intuitive.

[0004] However, when the above device is in use, the measurement width of the rollers is extremely limited, and it can only reflect the local flatness situation on the straight line where the rollers are located, and it is difficult to comprehensively represent the flatness of the entire road surface. In order to obtain more comprehensive road surface flatness data, the operator has to move the instrument repeatedly on the road surface and conduct multiple measurements, which not only increases the workload, but also significantly reduces the measurement efficiency.

[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] Please refer to Figures 1 to 4As shown in the figure, a flatness detection instrument for urban road pavement acceptance includes a vehicle body 1. Wheels 2 are installed on both sides of the outer surface of the vehicle body 1. A solar panel 3 is installed on the top of the vehicle body 1. A remote control receiver 4 is arranged on the front side of the vehicle body 1. A camera 5 is installed on the upper right side of the vehicle body 1. A controller 6 is installed at the center position on the top of the vehicle body 1. Connecting plates 7 are fixedly connected to the upper and lower opposite sides of the right side surface of the vehicle body 1. A lifting mechanism 8 is arranged between the two connecting plates 7. The lifting mechanism 8 includes a threaded rod 801 rotatably connected between the two connecting plates 7. A driving motor 802 is installed on the top of the upper connecting plate 7. The output end of the driving motor 802 extends to the bottom of the upper connecting plate 7 and is fixedly connected to one end of the threaded rod 801. Two sets of fixed rods 803 are also fixedly connected between the two connecting plates 7. The two sets of fixed rods 803 are symmetrically distributed on the opposite sides of the threaded rod 801. A movable plate 804 is threadedly connected to the outer peripheral surface of the threaded rod 801. The movable plate 804 is slidably connected to the two sets of fixed rods 803. When using this device, the solar panel 3 efficiently converts solar energy into electrical energy, providing continuous power for the wheels 2 on both sides of the vehicle body 1, realizing a green and environmentally friendly driving mode. Then, the operator can clearly observe and master the road conditions ahead with the cooperation of the remote control receiver 4 and the high-definition camera 5 by means of a remote control panel (not shown in the figure), ensuring the safety and smoothness of driving. Once the vehicle body 1 accurately reaches the road area to be detected, the driving motor 802 can be started. When the driving motor 802 drives the threaded rod 801 to descend, due to the precise guiding effect of the two sets of fixed rods 803, it is ensured that the movable plate 804 can slowly descend in a stable and controlled manner, smoothly transitioning to the next stage of detection or operation process, making the whole process smooth and efficient.

[0024] A detection mechanism 9 is provided on the outer surface of the lifting mechanism 8. The detection mechanism 9 includes a support plate 901 fixedly connected to the right side surface of the movable plate 804. A number of groups of springs 902 are fixedly connected to the bottom of the support plate 901 at equal linear intervals. One end of each spring 902 away from the support plate 901 is fixedly connected to a mounting bracket 903. A fixed column 904 is fixedly connected inside the mounting bracket 903. A rotating wheel 905 is rotatably connected to the outer peripheral surface of the fixed column 904. Laser emitters 906 are provided in the middle of the springs 902 and at the bottom of the support plate 901. Laser receivers 907 are provided in the middle of the springs 902 and at the top of the mounting bracket 903. The movable plate 804 drives the support plate 901 to descend until the springs 902 are in a moderately compressed state with the ground, and then it can stop. As the vehicle body 1 moves forward and the ground has potholes, due to the action of the springs 902, the rotating wheels 905 always keep in contact with the ground. It should be noted that the laser receivers 907 can flexibly adjust their positions as the mounting brackets 903 move up and down synchronously. Furthermore, the controller 6 can precisely analyze and process the relative height change signals emitted by the laser emitters 906 and received by the laser receivers 907, so as to comprehensively and accurately evaluate the flatness of the road surface, providing valuable data support for subsequent maintenance and improvement.

[0025] The working principle and usage process of this device: When using this device, the solar panels 3 efficiently convert solar energy into electrical energy, providing continuous power for the wheels 2 on both sides of the vehicle body 1, realizing a green and environmentally friendly driving mode. Then, the operator can clearly observe and master the road conditions ahead with the help of a remote control panel (not shown in the figure) through the coordinated action of the remote control receiver 4 and the high-definition camera 5 to ensure safe and smooth driving. Once the vehicle body 1 accurately arrives at the road area to be detected, the drive motor 802 can be started. When the drive motor 802 drives the threaded rod 801 to descend, due to the precise guiding action of the two fixed rods 803, it is ensured that the movable plate 804 can slowly descend in a stable and controlled manner, smoothly transitioning to the next stage of detection or operation process, making the whole process smooth and efficient.

[0026] The movable plate 804 drives the support plate 901 to descend until the springs 902 are in a moderately compressed state with the ground, and then it can stop. As the vehicle body 1 moves forward and the ground has potholes, due to the action of the springs 902, the rotating wheels 905 always keep in contact with the ground. It should be noted that the laser receivers 907 can flexibly adjust their positions as the mounting brackets 903 move up and down synchronously. Furthermore, the controller 6 can precisely analyze and process the relative height change signals emitted by the laser emitters 906 and received by the laser receivers 907, so as to comprehensively and accurately evaluate the flatness of the road surface, providing valuable data support for subsequent maintenance and improvement.
