Description

Technical Field

[0001] The utility model relates to the field of flatness detection equipment, in particular to high-precision road flatness detection equipment. Background Art

[0002] A road is a paved passage for vehicles, pedestrians or other means of transportation, usually including a road surface, shoulders, signs and traffic facilities. They are used to connect different locations and support traffic flow. The flatness of the road surface is crucial for driving safety. An uneven road surface will cause the vehicle to jolt and shake during driving, increasing the risk of vehicle out of control, especially when driving at high speed or in an emergency braking situation. Therefore, road flatness detection equipment is needed to measure and evaluate the flatness of the road surface. These devices can detect the unevenness, fluctuations and other irregularities of the road to ensure that the road meets the design specifications and provides a comfortable and safe driving environment.

[0003] The high-precision road flatness detection equipment is composed of a frame and a support structure, which is used to carry and stabilize the sensor. The sensor is used to measure the height change of the road surface. The flatness meter can be installed on a specially designed bracket or frame on the vehicle body to ensure the stability of the measuring equipment. Due to the interference caused by the uneven road or vehicle vibration, and because the fixing structure is relatively single, the vibration causes errors when carrying the flatness meter, thus reducing the measurement accuracy and stability. Therefore, a high-precision road flatness detection equipment is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a high-precision road flatness detection equipment, aiming to improve the problem of single fixing structure in the prior art, which causes errors due to vibration when carrying the flatness meter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, the vibration of the fixed frame drives the second connecting block to move, causing the connecting plate to rotate, and then the first connecting block moves accordingly, pushing the sliding ring to slide along the side wall of the fixed rod, squeezing the first spring and making it contract, so that the pressure is transmitted to the damper to absorb the vibration, solving the problem that the fixed structure of the traditional road flatness detection equipment is single, resulting in errors due to vibration when carrying the flatness meter, and improving the practicability of the equipment through the above technical solution.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a high-precision road surface flatness detection device, including a detection frame 1, a bearing frame 2 is fixedly connected to the upper surface of the detection frame 1, an installation frame 3 is fixedly connected to the upper surface of the bearing frame 2, a fixed frame 11 is slidably connected inside the installation frame 3, the fixed frame 11 is used to place a flatness meter, a damper 4 is fixedly connected to the lower surface of the fixed frame 11, the damper 4 is used to absorb vibration, the output end of the damper 4 is connected to the installation frame 3, a fixed rod 5 is fixedly connected inside the installation frame 3, a sliding ring 6 is slidably connected to the side wall of the fixed rod 5, a connecting block one 7 is fixedly connected to the side wall of the sliding ring 6, a connecting plate 8 is rotatably connected inside the connecting block one 7, a connecting block two 9 is fixedly connected to the lower surface of the fixed frame 11, the other end of the connecting plate 8 is rotatably connected inside the connecting block two 9, a first spring 10 is sleeved on the side wall of the fixed rod 5, and the first spring 10 is fixedly connected between the sliding rings 6. A detection wheel 23 is arranged on the lower surface of the bearing frame 2, and a roller 24 is arranged inside the detection frame 1. The roller 24 is used to drive the vehicle frame to move. A towing hook 25 is fixedly connected to the side wall of the bearing frame 2, and the towing hook 25 is used for tying and connecting with a vehicle;

[0032] During the operation of the device, first, the flatness meter needs to be placed in the internal space of the fixed frame 11. When the device encounters bumps or uneven roads during operation and thus generates vibrations, this vibration will be transmitted to the connecting block two 9 through the fixed frame 11. Under the action of the vibration, the connecting block two 9 will move correspondingly, and then drive the connecting plate 8 to rotate. The rotation of the connecting plate 8 will further cause the connecting block one 7 to move. The movement of the connecting block one 7 will further affect the sliding ring 6 fixed to the side wall, causing it to slide along the side wall of the fixed rod 5 towards the central position. During the sliding process, the sliding ring 6 will apply pressure to the first spring 10, causing the first spring 10 to contract. The contraction of the first spring 10 will transmit this pressure to the damper 4. The function of the damper 4 is to absorb vibration, thereby effectively reducing the degree of vibration transmitted to the measuring device. In this way, it can be ensured that the data received by the measuring device is more accurate, avoiding errors caused by vibration, and thus improving the overall measurement accuracy.

[0033] Refer to Figure 2 and Figure 4The lower surface of the carrier 2 is fixedly connected to a fixed frame 12, and a fixed plate 13 is fixedly connected to the inside of the fixed frame 12. A rotating shaft 14 is rotatably connected to the inside of the fixed frame 12. A gear 15 is fixedly connected to the side wall of the rotating shaft 14. The gear 15 is used to drive the gear 2 16 to rotate. The fixed frame 12 is rotatably connected to the gear 2 16. The gear 15 is meshed with the gear 2 16. The lower surface of the gear 2 16 is fixedly connected to a connecting rod 17. The lower surface of the connecting rod 17 is fixedly connected to a fixed disk 18. The lower surface of the fixed disk 18 is provided with a brush Head 21, the brush head 21 is used to clean the ground. A retraction assembly is provided on the lower surface of the fixed disk 18. The retraction assembly is used to keep the brush head 21 in parallel contact with the road surface. The retraction assembly includes a telescopic rod 19 and a second spring 20. The second spring 20 is used to enable the brush head 21 to maintain uniform contact pressure with the road surface. The side wall of the telescopic rod 19 is fixedly connected between the fixed disk 18 and the brush head 21. The second spring 20 is fixedly connected between the fixed disk 18 and the brush head 21. A motor 22 is provided inside the fixed frame 12, and the output end of the motor 22 is connected to the rotating shaft 14;

[0034] In order to ensure that there are no stones or other obstacles on the ground that interfere with the detection efficiency, first start the motor 22, so that it drives the rotating shaft 14 to start rotating. The rotation of the rotating shaft 14 will be further transmitted to gear 1 15, so that it also starts to rotate. Gear 1 15 is tightly engaged with gear 2 16, so gear 2 16 will also rotate accordingly. The rotation of gear 2 16 will be transmitted to the connecting rod 17, so that it also starts to rotate. The rotation of the connecting rod 17 drives the fixed disk 18 to rotate. The fixed disk 18 drives the brush head 21 to rotate during the rotation to perform a cleaning action, thereby cleaning the ground. In addition, a telescopic rod 19 is fixedly installed between the fixed disk 18 and the brush head 21. The function of the telescopic rod 19 is to guide the relative movement between the two to ensure smooth movement. At the same time, the presence of spring 20 enables the brush head 21 to maintain uniform contact pressure with the road surface, thereby improving the cleaning effect.

[0035] Working principle: When using the equipment, place the smoothness meter inside the fixed frame 11. When the equipment encounters bumps and vibrates, the vibration of the fixed frame 11 drives the connecting block 2 9 to move, causing the connecting plate 8 to rotate, and the movement of the connecting block 2 9 pushes the connecting block 1 7 to move. The movement of the connecting block 1 7 drives the sliding ring 6 fixed on the side wall to slide inward on the side wall of the fixed rod 5. The movement of the sliding ring 6 squeezes the spring 10 to contract it, and transfers the pressure to the damper 4, absorbing the generated vibration, reducing the degree of vibration transmitted to the measuring device, and ensuring the accuracy of the data.

[0036] To ensure that there are no obstacles such as stones on the ground affecting the detection efficiency, the motor 22 is started to make the rotating shaft 14 rotate. The rotation of the rotating shaft 14 drives the first gear 15 to rotate. The first gear 15 meshes with the second gear 16, thereby driving the second gear 16 to rotate. The rotation of the second gear 16 drives the connecting rod 17 to rotate, thereby making the fixed disk 18 rotate. The fixed disk 18 drives the brush head 21 to rotate to clean the ground. At the same time, a telescopic rod 19 is fixed between the fixed disk 18 and the brush head 21. The telescopic rod 19 can play a guiding role in their relative movement. At the same time, the second spring 20 makes the brush head 21 uniformly abut against the road surface.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
