This can lead to potholes or bumps, causing road deformation and affecting the safety of driving on the road. This is especially true for roads such as airport runways, racetracks, and experimental roads, which have extremely high requirements for road smoothness.

[0013] Step 1: Install the supporting circular plate into the appropriate position;

[0014] The device is used to observe whether the heights of the horizontal plates on both sides are consistent. If they are inconsistent, the adjusting screw is adjusted to make the heights of the horizontal plates on both sides consistent.

[0015] At this moment, the round-headed rod contacts the ground and compresses a section of the spring.

[0016] Step 2: Operate the electric push rod 2 to reciprocate and extend, control the motor 2 to rotate, and realize the reciprocating swing of the vertical plate to clear obstacles such as fallen leaves and gravel from the road surface;

[0017] Step 3: Control the motor to rotate, so that the detection component and the obstacle removal component move forward;

[0018] Step 4: When the round-headed rod encounters a protrusion, the round-headed rod moves along the protrusion, compresses the first spring, and drives the second round rod to move along the vertical groove. The second round rod drives the lower sensor to move along the height direction. The upper sensor measures the distance between itself and the lower sensor at intervals to obtain the height distribution of the protrusion.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] 1. This device uses markers distributed vertically. When encountering a protrusion or depression, the position of the round-headed rod changes under the action of spring one. Through the connection of link four, the markers swing. The hollow tube is limited by a stop block to keep the markers vertical, so that the markers mark the relative position and length of the protrusion or depression on the upper or lower white board.

[0025] 2. This device uses a sensor that reciprocates to detect the width of protrusions or depressions. When the sensor detects a depression with a large slope in the forward direction, it controls the electric push rod to retract, thus preventing damage to the round-headed rod.

[0026] 3. This device, through its ingenious design, calculates the height distribution and approximate length of protrusions and the depth distribution and approximate length of depressions by varying the distance between the upper and lower sensors. This data is then transmitted to a host computer. The reciprocating swing of the sensors detects the width distribution of the protrusions or depressions, thus achieving three-dimensional data collection.

[0045] The slider 11 is fixedly connected to symmetrical guide rods 12, and the guide rods 12 pass through the support rod 19.

[0046] A road inspection process includes the following steps:

[0047] Step 1: Install the support circular plate 8 into the appropriate position;

[0048] The device is used to observe whether the heights of the horizontal plates 1 on both sides are consistent. If they are inconsistent, the adjusting screw 9 is adjusted to make the heights of the horizontal plates 1 on both sides consistent.

[0049] At this time, the round-headed rod 18 contacts the ground and compresses a section of the spring 16;

[0050] Step 2: Operate the electric push rod 35 to reciprocate and extend, control the motor 34 to rotate, and realize the reciprocating swing of the vertical plate 40 to clear obstacles such as fallen leaves and gravel from the road surface;

[0051] Step 3: Control the rotation of motor 2 to move the detection component and the obstacle removal component forward;

[0052] Step 4: When the round-headed rod 18 encounters a protrusion, it moves along the protrusion, compressing the spring 16. The round-headed rod 18 then moves the round rod 20 along the vertical groove 17. The round rod 20 moves the lower sensor 50 along the height direction. The upper sensor 14 measures the distance between itself and the lower sensor 50 at intervals to determine the protrusion height distribution. The round rod 20 then causes the connecting rod 4 51 to swing, which in turn causes the round rod 3 26 to swing. The round rod 3 26 then moves the circular plate... 24. The circular shaft 25, the circular rod 27, the hollow tube 29, the spring 31, the marker 28, and the spring 30 swing, causing the upper marker 28 to quickly contact the upper whiteboard 5, and the upper hollow tube 29 to contact the stop block 23, making the upper marker 28 vertical. The upper marker 28 presses against the upper spring 31, and the circular rod 27 and the upper hollow tube 29 press against the upper spring 30. The upper marker 28 marks the relative position and length of the protrusion on the upper whiteboard 5.

[0053] Step 6: When the round-headed rod 18 encounters a depression, the spring 16 returns to its original state, the upper sensor 14 measures the distance between itself and the lower sensor 50 at intervals to obtain the depression depth distribution, and the marker pen 28 on the lower side marks the relative position and length of the depression on the lower white board 6.

[0054] When the electric push rod 35 reciprocates, it drives the U-plate 44 to swing back and forth. The electric push rod 35 swings back and forth, and the U-plate 44 drives the vertical rod 36, the vertical plate 40, and the sensor 41 to swing back and forth.

[0055] When the second motor 34 rotates, it drives the first gear 43 to rotate, the first gear 43 drives the second gear 45 to oscillate back and forth, the second gear 45 drives the first connecting rod 46 to oscillate back and forth, the first connecting rod 46 drives the T-shaped block 38 to move back and forth along the straight groove 37, the T-shaped block 38 drives the third connecting rod 48 to oscillate back and forth, the third connecting rod 48 drives the second connecting rod 47 to oscillate back and forth, the T-shaped block 38 drives the square rod 39 to move back and forth along the straight groove 37, and the square rod 39 drives the vertical plate 40 and the sensor 41 to move back and forth.

[0056] When the sensor 41 detects a depression with a large slope in the forward direction, it controls the electric push rod 13 to retract to avoid damage to the round-headed rod 18.

[0057] The first motor 2, the second motor 34, the first electric push rod 13, the second electric push rod 35, the upper sensor 14, the lower sensor 50, and the sensor 41 are electrically connected to the controller, and the controller is wirelessly connected to the host computer.

[0058] The workflow of this invention is as follows: the support circular plate 8 is installed in a suitable position, and the height of the two horizontal plates 1 on both sides is observed by setting the device. If they are not consistent, the adjusting screw 9 is adjusted to make the height of the two horizontal plates 1 on both sides consistent. At this time, the round head rod 18 contacts the ground and compresses a section of spring 16.

[0059] The electric push rod 2 35 is operated to reciprocate and extend, controlling the rotation of motor 2 34. When the electric push rod 2 35 reciprocates and extends, it drives the U plate 44 to swing back and forth. The U plate 44 drives the vertical rod 36, the rough vertical plate 40, and the sensor 41 to swing back and forth.

[0060] When motor 2 34 rotates, it drives gear 1 43 to rotate, which in turn drives gear 2 45 to oscillate back and forth. Gear 2 45 then drives connecting rod 1 46 to oscillate back and forth, which in turn drives T-block 38 to move back and forth along straight groove 37. T-block 38 then drives connecting rod 3 48 to oscillate back and forth, which in turn drives connecting rod 2 47 to oscillate back and forth. T-block 38 then drives square rod 39 to move back and forth along straight groove 37, which in turn drives the vertical plate 40 and sensor 41 to move back and forth. This allows the vertical plate 40 to oscillate back and forth, clearing obstacles such as fallen leaves and gravel from the road surface.

[0061] The control motor 12 rotates, enabling the detection and obstacle removal components to move forward. When the round-head rod 18 encounters a protrusion, it moves along the protrusion, compressing the spring 16. The round-head rod 18 then drives the round rod 20 to move along the vertical groove 17. The round rod 20 drives the lower sensor 50 to move along the height direction. The upper sensor 14 measures the distance between itself and the lower sensor 50 at intervals to determine the height distribution of the protrusion. The round rod 20 drives the connecting rod 4 51 to swing, which in turn drives the round rod 3 26 to swing. The round rod 3 26 then drives the circular plate 24. The components 25 (round shaft), 27 (round rod), 29 (hollow tube), 31 (spring), 28 (marker), and 30 (spring) swing, causing the upper marker 28 to quickly contact the upper white plate 5. The upper hollow tube 29 then contacts the stop block 23, making the upper marker 28 vertical. The upper marker 28 presses against the upper spring 31, while the round rod 27 and the upper hollow tube 29 press against the upper spring 30. The upper marker 28 marks the relative position and length of the protrusion on the upper white plate 5. When the round rod 18 encounters a depression, the spring 16 returns to its original position. The upper sensor 14 measures the distance between itself and the lower sensor 50 at intervals to determine the depression depth distribution. The lower marker 28 marks the relative position and length of the depression on the lower white plate 6.

[0062] When sensor 41 detects a depression with a large slope in the direction of travel, it controls the electric push rod 13 to retract to prevent damage to the round-head rod 18.

[0063] The device can detect the deepest indentation by adjusting the compression of spring 16 after adjusting screw 9.

[0064] Sensor 41 reciprocates to detect the width of the protrusion or depression.

[0065] The controller calculates the height distribution and approximate length of the protrusion and the depth distribution and approximate length of the depression by changing the distance between the upper sensor 14 and the lower sensor 50, and transmits the data to the host computer. The sensor 41 reciprocates to detect the width distribution of the protrusion or depression, thereby realizing the collection of three-dimensional data of the protrusion or depression.

[0066] This device uses vertically distributed markers 28. When encountering a protrusion or depression, the position of the round-headed rod 18 changes under the action of the spring 16. Through the connection of the connecting rod 51, the markers 28 swing. The hollow tube 29 is limited by the stop block 23 to keep the markers 28 vertical, so that the markers 28 mark the relative position and length of the protrusion or depression on the upper white board 5 or the lower white board 6.

[0067] This device uses a sensor 41 that reciprocates to detect the width of a protrusion or depression. When the sensor 41 detects a depression with a large slope in the forward direction, it controls the electric push rod 13 to retract, thus preventing damage to the round-headed rod 18.

[0068] This device, through its ingenious design, calculates the height distribution and approximate length of protrusions and the depth distribution and approximate length of depressions by varying the distance between the upper sensor 14 and the lower sensor 50. This data is then transmitted to a host computer. The reciprocating swing of sensor 41 detects the width distribution of the protrusions or depressions, thus achieving three-dimensional data collection. This facilitates the creation of three-dimensional models of the protrusions or depressions by staff, aiding in subsequent road maintenance.

[0069] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
