Description

An adjustable cleaning device for flatness testing of an eight-wheel instrument Technical Field

[0001] This utility model relates to the field of highway smoothness testing technology, and more specifically to an adjustable cleaning device for eight-wheel smoothness testing. Background Technology

[0002] The eight-wheel smoothness tester is a specialized instrument for testing the smoothness of high-grade highway pavements. It is frequently used in highway engineering construction, handover, final acceptance quality inspection, and defect investigation.

[0003] However, after the road surface construction is completed, other construction work will continue to be carried out on the newly completed road surface due to various reasons, which will inevitably cause pollution to the paved road surface. Even slight pollution can have a significant impact on the test of road surface smoothness.

[0004] For example, gravel particles may remain on the road surface. Larger particles are easy to sweep away, while smaller particles are difficult to remove. When using an eight-wheel flatness tester, many residual gravel particles will remain in front of the wheels. These particles will affect the movement of the tester, causing it to roll over the gravel and resulting in up-and-down shaking, which affects the measurement results. At the same time, as the tester moves, the measuring wheel also rotates and moves forward on the road surface. This up-and-down shaking can cause the measuring wheel to collide with the road surface, which can wear down or damage the measuring wheel, affecting its use and the accuracy of the measurement results.

[0005] Traditional eight-wheel road surface leveling instruments require manual labor to follow the vehicle and clear debris and stones from the road surface along the path of the instrument's sensing wheels when collecting road surface data. This manual cleaning is time-consuming, labor-intensive, and poses safety hazards when people and vehicles work together.

[0006] Therefore, developing a time-saving, labor-saving, safe, and efficient adjustable cleaning device for flatness testing of an eight-wheel instrument is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a time-saving, labor-saving, safe and efficient adjustable cleaning device for flatness testing of an eight-wheel instrument.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An adjustable cleaning device for flatness testing using an eight-wheel instrument includes:

[0010] The frame includes: a vertical rod and a connecting plate; the vertical rod and the connecting plate are vertically connected, and the other end of the connecting plate is connected to the front end of the main frame of the eight-wheel instrument; the top of the vertical rod is provided with threads, and the connecting plate is sleeved on the outside of the vertical rod and fastened with a nut;

[0011] A cleaning brush, which is V-shaped and located at the bottom of the vertical rod.

[0012] The beneficial effects of adopting the above technical solution are as follows: by setting a cleaning device at the front end of the eight-wheel instrument's main frame, the road surface can be cleaned to remove debris, sand, and other particles, thus ensuring that the eight-wheel instrument will not bounce up and down due to these obstacles during the testing process, ensuring normal contact between the measuring wheel and the road surface, and improving the accuracy of road surface smoothness testing; the cleaning device is connected to the eight-wheel instrument's main frame and can move with the instrument, eliminating the need for manual cleaning, avoiding the time and effort required for manual cleaning and the safety hazards of personnel and vehicles working together, making the cleaning process more time-saving and labor-saving, and improving the overall efficiency of the testing work; the vertical rod and the connecting plate are threaded together, making it easy to adjust the position of the connecting plate on the vertical rod and to connect the connecting plate to the eight-wheel instrument's main frame.

[0013] Preferably, a cleaning plate is connected to the bottom of the vertical rod, and the cleaning plate is connected to the cleaning brush. The cleaning plate is L-shaped, which can provide stable support for the cleaning brush, making the cleaning brush more stable during the cleaning process and less prone to loosening, thereby better completing the cleaning task and further improving the cleaning effect.

[0014] Preferably, the sweeping device further includes an auxiliary wheel, which is connected to a connecting rod, the other end of which is connected to the sweeping plate. The auxiliary wheel can provide support and guidance during the sweeping process, making the sweeping device move more smoothly and steadily.

[0015] Preferably, the top and bottom of the connecting plate are provided with nuts that connect to the vertical rod, and a washer is provided between the nut and the connecting plate. By adjusting the position of the nut on the vertical rod, the high position of the connecting plate on the vertical rod can be precisely adjusted. At the same time, by adjusting the position of the connecting plate, the connecting plate can press down on the vertical rod and the sweeping brush, thereby allowing the sweeping brush to make close contact with the ground according to the actual road conditions, better conform to the ground, and more thoroughly clean up debris, further improving the cleaning effect.

[0016] Preferably, a U-shaped clamping plate is provided at one end of the connecting plate that connects to the main frame of the eight-wheel instrument. The U-shaped clamping plate locks the main frame of the eight-wheel instrument and is secured with screws. This structure makes the connection between the cleaning device and the main frame of the eight-wheel instrument more secure and reliable, ensuring that the cleaning device will not loosen or fall off during the movement of the eight-wheel instrument, guaranteeing the stable operation of the cleaning device, and improving the reliability of the entire detection system.

[0017] Preferably, the screw is a hand-tightening screw, and a pressure plate is fitted around the outside of the hand-tightening screw. The pressure plate is located inside the U-shaped clamping plate and presses against the main frame of the eight-wheel instrument. The design of the hand-tightening screw makes the disassembly and assembly of the cleaning device more convenient and quick, and can be operated without the aid of tools. This facilitates the maintenance, replacement or adjustment of the cleaning device, and improves the maintainability and flexibility of the equipment.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an adjustable cleaning device for testing the flatness of an eight-wheel instrument, the beneficial effects of which are:

[0019] (1) A cleaning device is installed at the front end of the main frame of the eight-wheel instrument to clean the ground, which can ensure the accuracy of the eight-wheel instrument detection;

[0020] (2) The sweeping device moves together with the main frame of the eight-wheel instrument under the drive of the traction mechanism, which can save manual sweeping operations, making the sweeping process more time-saving, labor-saving, safe and efficient.

[0021] (3) The vertical rod and the connecting plate are threaded together, which makes it easy to adjust the height of the connecting plate on the vertical rod and to connect the connecting plate to the main frame of the eight-wheel instrument. At the same time, by adjusting the height of the connecting plate, the connecting plate can exert downward pressure on the vertical rod and the cleaning brush, so that the cleaning brush can fit with the ground, making the cleaning of debris more thorough and further improving the cleaning effect.
