Description

Technical Field

[0001] The utility model relates to the field of road detection, in particular to a road smoothness detection device. Background Art

[0002] Smoothness is a key indicator of pavement construction quality and service quality. Uneven pavement increases driving resistance and causes additional vibration in vehicles. This vibration can cause bumpy driving, impacting speed and safety, driving stability, and passenger comfort. Furthermore, vibration exerts impact force on the pavement, exacerbating damage to the pavement and vehicles, as well as tire wear. Uneven pavement can accumulate rainwater, accelerating road deterioration. Therefore, the testing and assessment of smoothness is a crucial component of highway construction and maintenance.

[0003] Most existing road flatness detection devices are driven by tires to move the flatness detection device. However, when the road conditions are poor, the tires are difficult to move smoothly on the road surface, which makes the road flatness detection device likely to shake and fall when moving, affecting the use of the device and reducing its practicality. Therefore, a road flatness detection device is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: a road flatness detection device described in the present invention comprises a support plate, a flatness detector is provided on the inner side of the support plate, a support block is movably connected to the outer side of the support plate, a flat gear is movably connected to the outer side of the support block, a tooth plate is meshed with the outer side of the flat gear, a lifting plate is fixedly connected between the tooth plates, the lifting plates are in two pairs, a tire is provided on the inner side of the lifting plate, a crawler is provided on the inner side of the lifting plate, a synchronization rod is fixedly connected to the inner side of the flat gear, a synchronization belt is movably connected to the outer side of the synchronization rod, and the flat gear is meshed with a tooth plate. A servo motor is fixedly connected to the outer side of the wheel, and the servo motor is fixedly connected to the support block. In this step, a toothed plate and a flat gear are set so that the two lifting plates on the inner side of the support block can move in opposite directions. Therefore, when the device faces smooth road conditions, the lifting plate can drive the tire to move in contact with the ground, and at the same time, the track is raised, so that the device can move quickly to complete the detection of smooth road conditions. When the road conditions are poor, the tire is raised and the track is lowered, so that the device can move close to the ground through the track, making it easier for the user to push the device stably to detect poor road conditions, thereby improving the stability of the device during detection.

[0006] Preferably, a connecting block is fixedly connected to the outer side of the support plate, and a first pin is slidably connected to the inner side of the connecting block. The first pin is slidably connected to the flatness detector. An adjustment groove is provided on the surface of the support plate, and a second pin is slidably connected to the inner side of the adjustment groove. The second pin is slidably connected to the support block. This step allows the flatness detector to be disassembled and replaced by arranging the first pin and the second pin, thereby replacing flatness detectors of different sizes when facing road surfaces of different widths, thereby expanding the versatility of the device. Through the second pin, the support block can adjust its tire or track position by connecting with different adjustment slots, so that it can be adjusted according to the width of the road surface, thereby adjusting the tire and track position when the road surface is too narrow, further expanding the versatility of the device.

In this step, by setting the spring rod and the pressure wheel, when the support block adjusts its position, the synchronization rods approach each other, which will cause the synchronization belt to loosen and slip. The spring rod pulls the pressure wheel to press against the synchronization belt, so that the synchronization belt can remain taut even after adjustment, thereby ensuring stable transmission of the synchronization rod and the synchronization belt, thereby improving the stability of the device.

[0008] Preferably, a power supply is fixedly connected to the outside of the support block, the power supply is electrically connected to the servo motor, and the power supply is electrically connected to a photovoltaic panel on the outside. In this step, by setting the power supply and the photovoltaic panel, the servo motor can work without connecting wires, and in sunny weather, the photovoltaic panel can be exposed to facilitate charging of the power supply, thereby improving the convenience and environmental friendliness of the device.

[0009] Preferably, a protective shell is fixedly connected to the upper side of the support block, and a slide is slidably connected to the inner side of the protective shell. By setting the protective shell and the slide, the power supply can be shielded by pulling the slide on rainy days to prevent the power supply from contacting rainwater, thereby improving the safety of the device.

[0010] Preferably, a third pin is slidably connected to the inner side of the skateboard, and the third pin is slidably connected to the protective shell. In this step, by setting the third pin, after the skateboard moves, the third pin can be inserted into the inner side of the skateboard for fixing, thereby improving the stability of the device.

[0011] The utility model is beneficial in that:

[0012] 1. The utility model provides a toothed plate and a flat gear, so that the two lifting plates inside the support block can move in opposite directions.

When the road conditions are poor, the tires are raised and the crawler tracks are lowered, so that the device can move close to the ground through the crawler tracks, making it easier for the user to push the device stably to detect poor road conditions, thereby improving the stability of the device during detection;

[0013] 2. The utility model provides a first latch and a second latch, so that the flatness tester can be disassembled and replaced, so that flatness testers of different sizes can be replaced when facing road surfaces of different widths, thereby expanding the versatility of the device. Through the second latch, the support block can adjust its tire or track position by connecting with different adjustment slots, so that it can be adjusted according to the width of the road surface, thereby adjusting the tire and track position when the road surface is too narrow, further expanding the versatility of the device.

In this step, the tooth plate 5 and the flat gear 4 are set so that the two lifting plates 6 on the inner side of the support block 3 can move in opposite directions. Therefore, when the device faces a smooth road condition, the lifting plate 6 can drive the tire 7 to move in contact with the ground, and at the same time, the track 8 is raised, so that the device can move quickly to complete the detection of smooth road conditions. When the road condition is poor, the tire 7 is raised and the track 8 is lowered, so that the device can move close to the ground through the track 8, so that the user can easily push the device to stably detect poor road conditions, thereby improving the stability of the device during detection.
