Description

Technical Field

[0001] The utility model relates to the technical field of concrete flatness measurement, in particular to a sliding concrete surface flatness testing device. Background Art

[0002] Pavement smoothness refers to the deviation of the longitudinal concavity and convexity of the road surface. Pavement smoothness is an important indicator in pavement evaluation and pavement construction acceptance. It mainly reflects the smoothness of the pavement longitudinal section curve. When the pavement longitudinal section curve is relatively smooth, it means that the pavement is relatively flat, or the flatness is relatively good. Otherwise, it means that the flatness is relatively poor. A good pavement requires good pavement flatness as well.

[0003] As shown in the reference case "Concrete Road Flatness Detection Device for Municipal Engineering" with announcement number "CN218233299U", by arranging threaded rods, adjustment blocks, and sliding rods, the detection position of the detection device can be adjusted, making it easier to detect the flatness of different locations on the road, thereby improving work efficiency.

[0004] Conventional methods for testing the flatness of concrete road surfaces typically use a flatness ruler. However, this method requires separate testing at each measuring point using a ruler, making the testing process very inconvenient.

[0005] Therefore, a sliding concrete surface flatness testing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problem and provide a sliding concrete surface flatness test device, which improves the conventional method of using a flatness ruler to measure the flatness of concrete road surfaces. However, this method requires a separate test with a ruler at each measuring point, which makes the testing process very inconvenient.

[0007] The utility model achieves the above-mentioned object through the following technical solutions: a sliding concrete surface flatness testing device, comprising: a mobile frame, a plurality of mobile wheels fixedly mounted on the outer side of the mobile frame, a flatness measuring ruler provided inside the mobile frame, and a mobile measuring mechanism for conveniently performing mobile measurement on the concrete surface, wherein the mobile measuring mechanism comprises a distance measuring wheel fixedly mounted on one side of the mobile frame, a detection component provided on one side of the mobile frame, and a cleaning component provided on one side of the mobile frame. When in use, the distance measuring wheel can be used to detect the measured distance each time, thereby ensuring that the measurement spacing of the flatness measuring ruler is the same, and the consistency and accuracy of the measurement can be maintained. In addition, the cleaning component is used to clean debris on the concrete surface during the measurement process to ensure the accuracy of the measurement result.

[0008] Preferably, the detection component includes an electric push rod fixedly mounted on one side of the mobile frame, a driving plate fixedly mounted on the output end of the electric push rod, a connecting frame provided on one side of the driving plate, and the flatness measuring ruler fixedly connected to the driving plate. When measuring, the electric push rod can move the driving plate downward, and the driving plate can synchronously drive the flatness measuring ruler downward, and the flatness measuring ruler moves down to the concrete surface, accurately contacts and measures the flatness of the surface. By adjusting the moving speed and range of the electric push rod, the pressure and contact depth of the flatness measuring ruler can be controlled to adapt to different test requirements and surface conditions.

[0009] Preferably, the detection assembly also includes a fixing rod fixedly mounted on one side of the driving plate, the connecting frame is rotatably connected to the fixing rod, a torsion spring is provided on the outer side of the fixing rod, and the other end of the torsion spring is fixedly connected to the connecting frame. When the flatness measuring ruler contacts the concrete surface, the connecting frame can be rotated to synchronously drive the flatness measuring ruler to adjust and measure when encountering an uneven ground, and the torsion spring is deformed during the adjustment. After the measurement, the flatness measuring ruler is reset synchronously by resetting the torsion spring, which is convenient for the next measurement.

[0010] Preferably, a push rod is fixedly installed on one side of the mobile frame, and the distance measuring wheel is located on one side of the push rod. When the mobile frame is moved, the push rod can be used to conveniently push the mobile frame to move, making it more convenient to drive the mobile frame to move.

[0011] Preferably, the cleaning assembly includes a fixed plate fixedly mounted on one side of the mobile frame, an air pump fixedly mounted on one side of the fixed plate, a guide plate provided on one side of the air pump, and a plurality of nozzles fixedly mounted on one side of the guide plate. When the mobile frame moves, gas can be input into the guide plate through the air pump, and the guide plate cleans the measuring path of the leveling measuring ruler through the plurality of nozzles. Such a setting can ensure that dust, gravel or other debris on the surface of the leveling measuring ruler is effectively removed before the leveling measuring ruler contacts the concrete surface, thereby improving the accuracy and reliability of the measurement results.

[0012] Preferably, the guide plate is arranged obliquely, and the plurality of nozzles are distributed equidistantly. The obliquely arranged guide plate allows the air flow to be directed more accurately to the concrete surface, while the equidistantly distributed nozzles ensure that the entire surface receives uniform cleaning pressure.

[0013] Preferably, the guide plate and the air pump are fixedly connected via a connecting pipe, and the fixed plate is located on one side of the electric push rod. When the guide plate is in use, the guide plate and the air pump can be stably connected so that the air pump can stably input gas to the guide plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. During use, the measuring wheel can be used to detect the measured distance each time, thereby ensuring that the measuring distance of the level measuring ruler is the same, which can maintain the consistency and accuracy of the measurement. In addition, the cleaning component is used to clean the debris on the concrete surface during the measurement process to ensure the accuracy of the measurement results;

[0016] 2. When the mobile frame moves, the air can be input into the guide plate through the air pump. The guide plate cleans the measuring path of the leveling ruler through multiple nozzles. This setting can ensure that the dust, gravel or other debris on the surface of the leveling ruler is effectively removed before it contacts the concrete surface, thereby improving the accuracy and reliability of the measurement results.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a sliding concrete surface flatness testing device includes: a mobile frame 1, a plurality of mobile wheels 11 are fixedly installed on the outside of the mobile frame 1, a flatness measuring ruler 2 is arranged inside the mobile frame 1, and a mobile measuring mechanism 3 is used to facilitate mobile measurement of the concrete surface. The mobile measuring mechanism 3 includes a distance measuring wheel 31 fixedly installed on one side of the mobile frame 1, a detection component 32 is provided on one side of the mobile frame 1, and a cleaning component 33 is provided on one side of the mobile frame 1. When in use, the distance measuring wheel 31 can be used to detect the measured distance each time, thereby ensuring that the measurement spacing of the flatness measuring ruler 2 is the same, and the consistency and accuracy of the measurement can be maintained. In addition, the cleaning component 33 is used to clean debris on the concrete surface during the measurement process to ensure the accuracy of the measurement results.

[0024] like Figure 2 and Figure 3As shown, the detection component 32 includes an electric push rod 321 fixedly mounted on one side of the mobile frame 1, and a driving plate 322 is fixedly mounted on the output end of the electric push rod 321. A connecting frame 323 is provided on one side of the driving plate 322. The flatness measuring ruler 2 is fixedly connected to the driving plate 322. When measuring, the electric push rod 321 can move the driving plate 322 downward, and the driving plate 322 can synchronously drive the flatness measuring ruler 2 to move downward. The flatness measuring ruler 2 moves down to the concrete surface, accurately contacts and measures the flatness of the surface. By adjusting the moving speed and range of the electric push rod 321, the pressure and contact depth of the flatness measuring ruler 2 can be controlled to adapt to different test requirements and surface conditions. The detection component 32 also includes a fixing rod 324 fixedly mounted on one side of the driving plate 322. The connecting frame 323 is rotatably connected to the fixing rod 324, and the outer sleeve of the fixing rod 324 is provided with a torsion spring 325, and the other end of the torsion spring 325 is fixedly connected to the connecting frame 323. When the level measuring ruler 2 contacts the concrete surface, the rotating connecting frame 323 can synchronously drive the level measuring ruler 2 to adjust and measure when encountering an uneven ground, and the torsion spring 325 is deformed during adjustment. After measurement, the level measuring ruler 2 is reset synchronously by resetting the torsion spring 325, making it convenient for the next measurement. A push rod 12 is fixedly installed on one side of the mobile frame 1, and the measuring wheel 31 is located on one side of the push rod 12. When the mobile frame 1 is moved, the push rod 12 can be used to conveniently push the mobile frame 1 to move, making it more convenient to drive the mobile frame 1 to move.

[0025] like Figure 2 and Figure 4 As shown, the cleaning assembly 33 includes a fixed plate 331 fixedly mounted on one side of the mobile frame 1, an air pump 332 fixedly mounted on one side of the fixed plate 331, a guide plate 335 provided on one side of the air pump 332, and a plurality of nozzles 333 fixedly mounted on one side of the guide plate 335. When the mobile frame 1 moves, the air pump 332 can be used to input gas to the guide plate 335, and the guide plate 335 cleans the measuring path of the leveling measuring ruler 2 through the plurality of nozzles 333. Such a setting can ensure that dust, gravel or other debris on the surface of the leveling measuring ruler 2 is effectively removed before it contacts the concrete surface, thereby To improve the accuracy and reliability of the measurement results, the guide plate 335 is set obliquely, and the multiple nozzles 333 are evenly distributed. The oblique guide plate 335 allows the air flow to be more accurately directed to the concrete surface, while the evenly distributed nozzles 333 ensure that the entire surface receives uniform cleaning pressure. The guide plate 335 and the air pump 332 are fixedly connected by a connecting pipe 334. The fixing plate 331 is located on one side of the electric push rod 321. When the guide plate 335 is in use, it can be stably connected to the air pump 332 through the guide plate 335, so that the air pump 332 can stably input gas to the guide plate 335.

[0026] When the utility model is in use, the electric push rod 321 can be made to move the driving plate 322 downward to allow the driving plate 322 to synchronously drive the leveling measuring ruler 2 to move downward, and the leveling measuring ruler 2 can be moved down to the concrete surface to accurately contact and measure the flatness of the surface. By adjusting the moving speed and range of the electric push rod 321, the pressure and contact depth of the leveling measuring ruler 2 can be controlled to adapt to different test requirements and surface conditions. When the leveling measuring ruler 2 contacts the concrete surface, the rotating connecting frame 323 can be used to synchronously drive the leveling measuring ruler 2 to adjust the surface flatness. Adjustments are made synchronously for measurement, and the torsion spring 325 is deformed during the adjustment. After the measurement, the leveling measuring ruler 2 is reset synchronously by resetting the torsion spring 325, so as to facilitate the next measurement. When the mobile frame 1 moves, the air pump 332 can be used to input gas to the guide plate 335, and the guide plate 335 cleans the measuring path of the leveling measuring ruler 2 through multiple nozzles 333. Such a setting can ensure that dust, gravel or other debris on the surface of the leveling measuring ruler 2 is effectively removed before it contacts the concrete surface, thereby improving the accuracy and reliability of the measurement results.
