Description

Technical Field

[0001] This utility model relates to the field of highway smoothness testing technology, and in particular to a portable highway smoothness testing device. Background Technology

[0002] Highway smoothness testing refers to the process of measuring and evaluating the smoothness of road surfaces. This process is crucial for ensuring the safety, comfort, and efficiency of road traffic. Good road surface smoothness not only improves the driving experience and reduces vehicle wear, but also reduces fuel consumption and exhaust emissions, and extends the service life of roads.

[0003] Existing road smoothness testing methods typically involve using mobile road smoothness testing vehicles. These vehicles move along uneven road surfaces, pressing test rollers upwards. This causes contact plates on the test rollers to press against pressure testing plates, and the road smoothness is assessed based on the changes in pressure readings on the pressure testing plates. However, during testing, only a single test roller is used to inspect the road surface, resulting in a small inspection range. This necessitates repeated inspections of different locations on the road surface, leading to low efficiency and inconvenience.

[0004] Therefore, there is a need to design a portable highway smoothness testing device that can expand the detection range, facilitate the preliminary identification of uneven road surfaces, simplify operation procedures, and improve work efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing highway smoothness testing methods, which rely solely on a single test roller for inspection, resulting in a small testing range and inefficiency due to the need for repeated testing of different locations on the road surface, this invention provides a portable highway smoothness testing device that expands the testing range, facilitates the preliminary identification of uneven road surfaces, simplifies operation procedures, and improves work efficiency.

[0006] A portable road smoothness testing device includes a base wheel, a first telescopic rod, a connector, a first screw, a test roller, a spring, a contact piece, a pressure testing piece, a connecting frame, a sliding frame, a support frame, and an extension assembly. The first telescopic rod has a support frame rotatably connected to its telescopic end and a support frame rotatably connected to its fixed end. Both the front and rear parts of the support frame are rotatably connected to the base wheel. Connectors are connected to both the fixed and telescopic ends of the first telescopic rod. A first screw is threadedly connected to the left side of the fixed end of the first telescopic rod, and the first screw contacts the telescopic end of the first telescopic rod. A first motor is connected to the lower side of the fixed end of the first telescopic rod. A connecting frame is connected to the output shaft of the first motor. A sliding frame is slidably connected to the connecting frame. A spring connects the sliding frame and the connecting frame. A test roller is rotatably connected to the lower part of the sliding frame. A contact piece is connected to the upper right side of the connecting frame. A pressure testing piece is connected to the lower middle part of the fixed end of the first telescopic rod. An extension assembly capable of expanding the testing range is provided on the sliding frame.

[0007] Furthermore, it also includes shock absorbers, with shock absorbers rotatably connected to the adjacent support frame on both the front and rear sides of the connecting frame.

[0008] Furthermore, the extension assembly includes a test side roller, a second telescopic rod, a second screw, and a limiting rod. The sliding frame is connected to the front and rear sides of the second telescopic rod. The test side roller is rotatably connected to the telescopic end of the second telescopic rod. The left side of the fixed end of the second telescopic rod is threadedly connected to the second screw. The second screw contacts the telescopic end of the adjacent second telescopic rod. The telescopic end of the second telescopic rod is connected to the limiting rod, and the limiting rod contacts the connecting frame.

[0009] Furthermore, it also includes a pull rod, with the right side of the fixed end of the first telescopic rod connected to the pull rod.

[0010] Furthermore, it also includes a second motor and a cleaning brush head. A bracket is provided on the left side of the telescopic end of the first telescopic rod, and a second motor is connected to the lower side of the bracket. A cleaning brush head is connected to the output shaft of the second motor.

[0011] Furthermore, it also includes a controller, which is connected to the upper side of the connector near the pull rod, and both the first motor and the second motor are connected to the controller via wires.

[0012] The beneficial effects of this utility model are as follows: 1. By rotating and loosening the second screw, the second telescopic rod is extended, which drives the limiting rod to move outward, so that the test side roller moves outward and contacts the detection position, thereby expanding the detection range, facilitating the preliminary determination of uneven road surface areas, simplifying operation steps, and improving work efficiency.

[0013] 2. This utility model starts a second motor to drive the sweeping brush head to rotate, and the sweeping brush head cleans the road surface to be tested, so that the road surface can be cleaned before testing, avoiding the influence of stones or other impurities on the road surface on the test results.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A portable road smoothness testing device, such as Figures 1-4 As shown, the assembly includes a base wheel 1, a shock absorber 2, a first telescopic rod 3, a connector 31, a first screw 4, a test roller 8, a spring 9, a contact piece 10, a pressure detection piece 11, a pull rod 12, a connecting frame 131, a sliding frame 132, a support frame 14, a controller 18, and an extension assembly. The support frame 14 is rotatably connected to both the telescopic and fixed ends of the first telescopic rod 3. Base wheels 1 are rotatably connected to both the front and rear ends of the support frame 14. Connectors 31 are connected to both the fixed and telescopic ends of the first telescopic rod 3. A first screw 4 is threadedly connected to the left side of the fixed end of the first telescopic rod 3, and the first screw 4 contacts the telescopic end of the first telescopic rod 3. A pull rod 12 is connected to the right side of the fixed end of the first telescopic rod 3. A first motor 13 is connected to the lower side of the fixed end of the first telescopic rod 3. A connecting frame 131 is connected to the output shaft of the first motor 13. Shock absorbers 2 are rotatably connected to the front and rear parts of the connecting frame 131 and the adjacent support frame 14. A sliding frame 132 is slidably connected to the connecting frame 131. A spring 9 is connected between the sliding frame 132 and the connecting frame 131. A test roller 8 is rotatably connected to the lower part of the sliding frame 132. A contact piece 10 is connected to the upper right side of the connecting frame 131. A pressure detection piece 11 is connected to the lower middle part of the fixed end of the first telescopic rod 3. A controller 18 is connected to the upper side of the connecting piece 31 near the pull rod 12. The first motor 13 and the second motor 16 are both connected to the controller 18 through wires. An extension component is provided on the sliding frame 132.

[0021] like Figures 1-3 As shown, the extension assembly includes a test side roller 5, a second telescopic rod 6, a second screw 7, and a limiting rod 15. The sliding frame 132 is connected to the front and rear sides of the second telescopic rod 6. The test side roller 5 is rotatably connected to the telescopic end of the second telescopic rod 6. The left side of the fixed end of the second telescopic rod 6 is threadedly connected to the second screw 7. The second screw 7 is in contact with the telescopic end of the adjacent second telescopic rod 6. The limiting rod 15 is connected to the telescopic end of the second telescopic rod 6. The limiting rod 15 is in contact with the connecting frame 131.

[0022] When using this equipment, first move the equipment to the road smoothness testing area, then loosen the first screw 4, and then extend the first telescopic rod 3 so that the support frames 14 are far apart. Then tighten the first screw 4, and then start the first motor 13 through the controller 18 to drive the connecting frame 131 to rotate downward so that the connecting frame 131 and the first telescopic rod 3 are in a parallel state, so that the test roller 8 contacts the road surface wheel track. Then loosen the second screw 7, and then extend the second telescopic rod 6 to drive the limit rod 15 to move outward, so that the test side roller 5 moves outward and contacts the testing position. Then hold the pull rod 12 and push it to drive the bottom wheel 1 and the test roller 8 to rotate.

[0023] When the road surface between the test side roller 5 and the test roller 8 is uneven, the test roller 8 and the test side roller 5 will be squeezed upwards, causing the sliding frame 132 to move upwards. The spring 9 will be compressed and contracted, causing the contact piece 10 to contact the pressure detection piece 11. The road surface smoothness of a large area will be initially detected based on the pressure value change detected by the pressure detection piece 11. Then, the second screw 7 will be rotated and loosened to retract the test side roller 5, causing the second telescopic rod 6 to retract. The second screw 7 will then be rotated and tightened again. The above detection steps will be repeated to further detect the uneven area of ​​the road surface, thereby expanding the detection range, facilitating the preliminary identification of the uneven area of ​​the road surface, simplifying the operation steps, and improving work efficiency. When the road surface is smooth, the spring 9 will return to its original state, causing the sliding frame 132 to move downwards and reset, so that the contact piece 10 no longer contacts the pressure detection piece 11. During the movement of this equipment, when the bottom wheel 1 contacts the uneven surface, the support frame 14 will rotate, and the shock absorber 2 will provide shock absorption.

[0024] like Figure 3 and Figure 4 As shown, it also includes a second motor 16 and a cleaning brush head 17. A bracket is provided on the left side of the telescopic end of the first telescopic rod 3. The second motor 16 is connected to the lower side of the bracket, and the cleaning brush head 17 is connected to the output shaft of the second motor 16.

[0025] Before inspecting the road surface, the second motor 16 is started, which drives the sweeping brush head 17 to rotate. The sweeping brush head 17 cleans the road surface to be inspected, thus cleaning before inspection and avoiding the impact of stones or other impurities on the road surface on the inspection results.
