Description

Technical Field

[0001] This application relates to the field of pavement deflection detection technology, and more specifically, to an adjustable highway pavement deflection detection device. Background Technology

[0002] An adjustable pavement deflection testing device is used to detect and evaluate the quality of highway pavements. It primarily determines the pavement's load-bearing capacity and health by measuring the deflection of the pavement under traffic loads. This device is commonly used for pavement structure quality inspection, assessing pavement maintenance needs, and providing data support during highway construction and maintenance.

[0003] This device typically consists of sensors, measuring rods, a support system, and adjustment mechanisms. By placing the device on the road surface and applying a certain load (simulating vehicle passage), the sensors can monitor changes in road surface deflection in real time. By comparing road surface settlement under different loads, the strength and stability of the road surface can be evaluated.

[0004] Deflection Testing: Precise sensors measure road surface deflection to assess its load-bearing capacity. Adjustability: The device's load, measurement range, and other parameters can be adjusted to suit different road conditions and testing requirements, providing flexible testing options. Data Recording and Analysis: Data is automatically recorded, and software analysis reveals specific deflection values ​​and corresponding road health conditions, providing valuable information for engineers. Convenience and Mobility: Typically designed for easy transport and movement, this device is suitable for use on various road sections and in diverse scenarios.

[0005] Adjustable road surface deflection testing devices, with their high-precision deflection measurement technology and flexible adjustable functions, are widely used in the construction, maintenance and management of highways. They can effectively improve the efficiency and accuracy of road surface quality testing, help engineers to discover potential problems in a timely manner, and ensure the safety and durability of highways.

[0006] The prior art publication CN113945194A provides a deflection measuring device for highway maintenance and testing. This device can provide continuous and stable support for the deflection measuring instrument body and can easily adjust the height of the deflection measuring instrument body. Therefore, when testing the road surface, it is not necessary to manually hold the deflection measuring instrument body continuously, which can reduce the road surface measurement error and has good practicality.

[0007] Although the existing technical solutions mentioned above can achieve the relevant beneficial effects through the structure of the existing technology, they still have the following defects: When the existing technology is used on the road, when dump trucks pass by, a large amount of soil will fall onto the road and be compacted. Since the existing technology is not convenient for cleaning the soil on the road, the detection data will have errors and its practicality is poor.

[0008] In view of this, we propose an adjustable highway pavement deflection detection device. Utility Model Content

[0026] Please refer to Figures 1-3. This application provides a technical solution:

[0027] An adjustable highway pavement deflection testing device includes a movable base 1, a deflection meter body 2, a reciprocating screw 3, a movable frame 4, and a soil-shoveling mechanism 5. The deflection meter body 2 is installed on the movable base 1.

[0028] The reciprocating screw 3 is rotatably connected to the movable seat 1;

[0029] The movable frame 4 is slidably fitted onto the reciprocating lead screw 3;

[0030] The soil-moving mechanism 5 is slidably mounted on the mobile frame 4.

[0031] Specifically, a motor 301 is fixedly connected to one end of the reciprocating screw 3, and the motor 301 is fixedly connected to the movable seat 1. A drive wheel 302 is fixedly connected to one end of the reciprocating screw 3, and a driven wheel 303 is meshed and driven on one side of the drive wheel 302. A transmission rod 304 is fixedly connected to the driven wheel 303, and the transmission rod 304 is rotatably connected to the movable frame 4.

[0032] Furthermore, a rotating sleeve 401 is rotatably connected to one end of the movable frame 4, and a cam 402 is fixedly connected to the rotating sleeve 401.

[0033] Furthermore, the soil-shoveling mechanism 5 includes a sliding frame 501, which is slidably coupled to the movable frame 4, and a soil-shoveling plate 502 is rotatably connected to the sliding frame 501.

[0034] In addition, an electric actuator 503 is rotatably connected to the sliding frame 501, and the other end of the electric actuator 503 is rotatably connected to the shovel plate 502. A sliding frame 504 is fixedly connected to one end of the sliding frame 501, and the inner wall of the sliding frame 504 is slidably engaged with the outer wall of the cam 402.

[0035] The implementation principle of the adjustable highway pavement deflection testing device in this application embodiment is as follows: When it is necessary to test the deflection of the pavement, the soil on the pavement must first be cleaned. The electric actuator 503 drives the shovel plate 502 to rotate to a suitable angle so that one end can contact the ground. Then, the motor 301 drives the reciprocating screw 3 to rotate, so that the reciprocating screw 3 can drive the drive wheel 302 to rotate. At the same time, the reciprocating screw 3 can drive the moving frame 4 to move. At this time, the drive wheel 302 will drive the transmission rod 304 connected to the driven wheel 303 to rotate. Then, the transmission rod 304 will drive the rotating sleeve 401 to rotate, so that the cam 402 on the rotating sleeve 401 rotates in the sliding frame 504, thereby driving the sliding frame 501 connected in the sliding frame 504 to move back and forth, so that the shovel plate 502 moves back and forth to clean the soil on the pavement. After cleaning, the deflection meter body 2 is lowered to test the deflection of the pavement.
