[0002] The core function of road damage detection equipment is to efficiently, accurately, and automatically identify and assess various road surface damage and potential structural issues. Road damage detection equipment primarily relies on sensors such as cameras, lasers, and radars to collect road surface data and convert it into objective, standardized, and digitized asset data.

[0036] 3. When the two mounting brackets move away from each other, the anti-slip grooves on the bottom of the anti-slip bracket prevent the anti-slip bracket from sliding, and elastic extrusion causes contact friction between the anti-slip bracket and the ground, so that the contact position between the anti-slip bracket and the ground is the center point. The two mounting brackets move away from each other along the contact position between the anti-slip bracket and the ground, so that when the two mounting brackets move away from each other, the road disease detector and the ground do not move, reducing the center point offset generated when the two mounting brackets move away from each other, and there is no need to adjust the position of the road disease detector again.

[0047] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0048] like Figures 1 to 9 The transport device for road defect detection equipment shown in the figure includes two mounting frames 1, each of which is equipped with a front wheel 2 and a rear wheel 3 on a side away from each other, and further includes:

[0049] The rectangular rod 4 is set between the two mounting frames 1, and both sides of the rectangular rod 4 are rotatably connected to multiple movable rods 5 (such as Figure 5 and Figure 6 As shown), one end of the movable rod 5 is rotatably connected to the corresponding mounting frame 1;

[0050] Sliding block 6, sliding block 6 is slidably connected to rectangular rod 4, both sides of sliding block 6 are rotatably connected to matching rod 7, one end of matching rod 7 is rotatably connected to the corresponding mounting frame 1;

[0051] The first electric cylinder 8 is rotatably connected to one side of the corresponding movable rod 5, and the transmission shaft of the first electric cylinder 8 is rotatably connected to one side of the rectangular rod 4;

[0052] Two mounting bars 9, the two mounting bars 9 are respectively located at the bottom of the two mounting frames 1, and the bottom of each mounting bar 9 is rotatably connected to a plurality of auxiliary wheels 10, the axes of the auxiliary wheels 10 and the rear wheels 3 are perpendicular to each other, and the mounting bars 9 are connected to a matching load-bearing component;

[0053] A road damage detector 11 is provided above one end of the rectangular rod 4, and a positioning assembly is connected between the road damage detector 11 and the rectangular rod 4;

[0054] A strip frame (15), the strip frame (15) is fixedly connected to the top of the rectangular rod (4), and a drive unit is installed on the rear wheel (3);

[0055] A battery is installed on the mounting frame 1, a drive unit is installed on the rear wheel 3, and a steering unit is installed on the front wheel 2. Both the drive unit and the steering unit are installed with signal receivers and are controlled by a remote control unit. The inspector controls the rotation of the rear wheel 3 and the steering of the front wheel 2 through the remote control unit, so that the road disease detector 11 is close to the collapsed road while the inspector and the manned vehicle can stay away from the collapsed area, reducing the further expansion of the collapsed area and ensuring the safety of the inspector.

[0056] Before approaching the collapsed part of the road, the first electric cylinder 8 is operated to move the transmission shaft of the first electric cylinder 8 outward, and an external force is applied along the rotation connection of the rectangular rod 4, so that the two ends of the corresponding movable rod 5 rotate along the rotation connection respectively, so that the rectangular rod 4 and the corresponding mounting frame 1 are separated from each other;

[0057] When the rectangular rod 4 and the mounting frame 1 on one side of the movable rod 5 move away from each other, the two ends of the matching rod 7 on the same side rotate synchronously with the moving distance between the rectangular rod 4 and the mounting frame 1, and in the process of rotating the matching rod 7, the sliding block 6 is driven to slide along the sliding connection of the rectangular rod 4, and the two ends of the matching rod 7 on the other side are driven to rotate synchronously, so that the two mounting frames 1 move away from the rectangular rod 4 synchronously, and the rectangular rod 4 is always located at the center position of the two mounting frames 1. When the two mounting frames 1 move away from each other, the distance between the two rear wheels 3 increases, and at the same time, the distance between the two front wheels 2 increases, so that the transport device can adjust the wheel spacing on both sides according to the size of the pothole at the collapsed position, so that the transport device can move over the collapsed position and drive the road disease detector 11 to perform intuitive scanning and detection of the inside of the pothole formed by the collapse, thereby improving the efficiency of data collection on the cause of the accident;

[0058] After the collapsed road detection is completed, the two mounting frames 1 are moved closer to each other by the reverse movement of the transmission shaft of the first electric cylinder 8, thereby reducing the degree of road occupancy and preventing the road disease detector 11 from affecting the traffic in other lanes during normal road detection.

[0059] During the process of the two mounting frames 1 moving away from each other, the rotation direction of the two rear wheels 3 and the moving direction of the mounting frames 1 always remain perpendicular. As a result, when the two rear wheels 3 move away from each other, the contact points between the rear wheels 3 and the ground are prone to significant wear and tear, and the resistance of the mounting frames 1 moving away is increased. By cooperating with the load-bearing components, the auxiliary wheels 10 are driven to descend and contact the ground, so that the front wheels 2 and the rear wheels 3 are suspended. Since the auxiliary wheels 10 are parallel to the moving direction of the mounting frames 1, when the two mounting frames 1 move away from each other, the auxiliary wheels 10 roll in contact with the ground, reducing the resistance of the mounting frames 1 moving away and preventing wear of the front wheels 2 and the rear wheels 3 when they move.

[0060] As a further embodiment of the present invention, the supporting components include:

[0061] A limit housing 12 is provided at the bottom of the rectangular rod 4. A plurality of first limit pins 13 are fixedly connected to both sides of the limit housing 12. The first limit pins 13 are slidably inserted into the corresponding mounting bars 9. A plurality of second limit pins 14 are fixedly connected to the top of the mounting bars 9. The second limit pins 14 are slidably inserted into the corresponding mounting brackets 1.

[0062] A second electric cylinder 16 is fixedly mounted on the top of the strip frame 15. The transmission shaft of the second electric cylinder 16 passes through the rectangular rod 4 and extends to the bottom of the rectangular rod 4 and is then fixedly connected to the limit housing 12.

[0063] When the second electric cylinder 16 is working, the transmission shaft of the second electric cylinder 16 moves vertically downward and drives the limit housing 12 to move downward synchronously. The limit housing 12 is connected to the sliding connection of the first limit pin 13 and the mounting bar 9, so that the mounting bar 9 moves vertically downward and drives the second limit pin 14 to move along the sliding plug-in point of the mounting frame 1. When the auxiliary wheel 10 at the bottom of the mounting bar 9 contacts the ground and continues to move downward, the auxiliary wheel 10 replaces the contact between the front wheel 2 and the rear wheel 3 and the ground, and makes the front wheel 2 and the rear wheel 3 in a suspended state, and when the two mounting frames 1 move away from each other, the mounting bar 9 is connected to the mounting frame 1 by the sliding plug-in action of the second limit pin 14, and moves synchronously with the corresponding mounting frame 1, so that the auxiliary wheel 10 at the bottom of the mounting bar 9 rolls along the moving direction of the mounting frame 1, reducing the friction resistance generated when the two mounting frames 1 move away from each other, and preventing contact wear caused by inconsistency between the rotation direction of the front wheel 2 and the moving direction of the rear wheel 3.

[0064] As a further embodiment of the present invention, an anti-slip frame 17 is slidably connected to the interior of the limit housing 12. The bottom surface of the anti-slip frame 17 is provided with anti-slip grooves and is located below the auxiliary wheel 10. A plurality of springs 18 are provided inside the limit housing 12 and are fixedly connected between the limit housing 12 and the anti-slip frame 17.

[0065] When the limiting shell 12 drives the mounting bars 9 on both sides to move downward, the bottom of the anti-skid frame 17 contacts the ground before the auxiliary wheel 10, and in the process of the auxiliary wheel 10 contacting the ground, the anti-skid frame 17 moves toward the inside of the limiting shell 12 under the action of the load-bearing action, and squeezes the spring 18 to produce compression deformation, so that when the auxiliary wheel 10 contacts the ground, the anti-skid frame 17 contacts the ground synchronously due to the elastic squeezing of the spring 18. When the two mounting frames 1 move away from each other, the anti-skid frame 17 is prevented from sliding by the anti-skid grooves at the bottom of the anti-skid frame 17, and the anti-skid frame 17 generates contact friction with the ground through elastic squeezing, so that the contact position of the anti-skid frame 17 with the ground is the center point, and the two mounting frames 1 move away from each other along the contact position of the anti-skid frame 17 with the ground, so that when the two mounting frames 1 move away from each other, the road disease detector 11 does not move with the ground, reducing the center point offset generated when the two mounting frames 1 move away from each other, and there is no need to adjust the position of the road disease detector 11 again.

[0066] As a further embodiment of the present invention, the positioning assembly comprises:

[0067] Two fixing brackets 19 (such as Figure 2 As shown), the two fixing frames 19 are both arranged on the top of the strip frame 15;

[0068] Two sliders 20 are slidably connected to the bar frame 15. A fixing frame 19 is fixedly connected to the top of the corresponding slider 20. The road disease detector 11 is fixedly mounted on one of the fixing frames 19. A counterweight 21 is fixedly mounted on the other fixing frame 19. A driving assembly is provided between the two sliders 20 for driving the two sliders 20 away from each other.

[0069] When the pothole formed by road collapse is too large and the two mounting frames 1 are still unable to pass through even after moving away from each other to the maximum distance, the inspector drives the mounting frame 1 to move to the vicinity of the pothole formed by the road collapse through the remote control unit, and drives the two sliders 20 to move away from each other along the sliding connection of the strip frame 15 through the action of the driving component. The fixed frame 19 on which the road disease detector 11 is installed approaches the center above the pothole as the slider 20 moves, and uses the detection end at the bottom of the road disease detector 11 to scan and detect the inside of the pothole. In the process of the road disease detector 11 approaching the pothole, the other fixed frame 19 drives the counterweight block 21 to move in the opposite direction, thereby reducing the center of gravity offset caused by the movement of the road disease detector 11, and preventing the movement of the road disease detector 11 from causing the transport device to tilt and fall into the pothole.

[0070] As a further embodiment of the present invention, the drive assembly comprises:

[0071] Bidirectional screw 22 (such as Figure 8As shown), the bidirectional screw 22 is rotatably connected to the inside of the strip frame 15, and a motor 23 is fixedly mounted on the strip frame 15, and the output shaft of the motor 23 is fixedly connected to one end of the bidirectional screw 22;

[0072] Two connecting blocks 24, the two connecting blocks 24 are fixedly connected to the bottom of the two sliders 20, and the two connecting blocks 24 are both threadedly connected to the bidirectional screw 22;

[0073] A signal receiver is installed on the motor 23 and is controlled by a remote control unit. The inspector controls the rotation of the output shaft of the motor 23 from a distance through the remote control unit, and drives the bidirectional screw 22 to rotate synchronously. The bidirectional screw 22 is threadedly connected to the two connecting blocks 24, so that the two sliders 20 move away from each other along the sliding connection of the strip frame 15, and drive the road disease detector 11 to move toward the pothole.

[0074] As a further embodiment of the present invention, two mounting grooves 25 are provided on the upper and lower sides of the slider 20, and a plurality of contact rollers 26 are rotatably connected inside the mounting grooves 25, and the contact rollers 26 are in contact with the strip frame 15;

[0075] The contact roller 26 inside the mounting groove 25 contacts the strip frame 15. When the slider 20 moves along the strip frame 15, the contact roller 26 rotates in cooperation at the contact position of the strip frame 15, thereby reducing the friction resistance generated during the movement and improving the smoothness of the movement of the slider 20 during the load-bearing process.

[0076] As a further embodiment of the present invention, connecting pins 27 are fixedly connected to both sides of the strip frame 15 near one end of the road defect detector 11. A rotating bracket 28 is rotatably connected to the connecting pin 27. A torsion spring 29 is fixedly installed at the rotating connection between the rotating bracket 28 and the connecting pin 27. A flip assembly is connected to the rotating bracket 28. When the fixed frame 19 moves along the strip frame 15, the flip assembly drives the rotating bracket 28 to rotate and support it on the ground.

[0077] When the fixed frame 19 drives the road defect detector 11 to move along the sliding connection of the strip frame 15, the rotating bracket 28 is driven to flip along the rotating connection of the connecting pin 27 through the action of the flip assembly, so that one end of the rotating bracket 28 is tilted and supported on the ground at the edge of the pothole. When the road defect detector 11 approaches the center above the pothole, the end of the transport device close to the pothole is supported by the rotating bracket 28, thereby further improving the stability of the transport device and preventing the transport device from tilting.

[0078] As a further embodiment of the present invention, the flip assembly comprises:

[0079] Two circular pins 30, the two circular pins 30 are respectively fixedly connected to the top ends of the two rotating brackets 28, and the circular pins 30 are both located at the top of the strip frame 15;

[0080] Two guide bars 31 are fixedly connected to the two sides of the corresponding fixing frame 19 (such as Figure 2 As shown), the guide bar 31 (as Figure 9 A guiding slope is provided on one end of the circular pin 30;

[0081] When the road defect detector 11 moves with the corresponding fixed frame 19, the guide bars 31 on both sides of the fixed frame 19 approach the corresponding circular pin 30, and through the contact and extrusion of the guiding inclined surface and the circular pin 30, the circular pin 30 moves to the top of the guide bar 31, and at the same time, the rotating bracket 28 is flipped along the rotating connection of the connecting pin 27, and the torsion spring 29 is driven to twist, so that the bottom end of the rotating bracket 28 is flipped and supported on the ground. When the road defect detector 11 returns to the initial position with the corresponding fixed frame 19, the circular pin 30 loses the guiding effect of the guide bar 31, and is returned to its original position through the twisting of the torsion spring 29, so that the bottom end of the rotating bracket 28 is flipped upward and retracted, reducing the impact on the movement of the transport device.

[0082] As a further embodiment of the present invention, a distance sensor 32 (such as Figure 1 and Figure 5 As shown), the distance sensors 32 are respectively located at the corresponding front wheels 2, and a controller is connected between the drive unit for driving the rear wheels 3 to rotate and the two distance sensors 32;

[0083] By installing a distance sensor 32 at the front wheel 2, the ground height in the moving direction of the front wheel 2 is detected. When the ground monitoring height of any moving position of the front wheel 2 reaches the maximum value, the controller connected to the distance sensor 32 simultaneously stops the drive unit from driving the two rear wheels 3, preventing the inspection personnel from causing the transport equipment to fall into a pothole through erroneous operation of the remote control unit, thereby ensuring the safety of the transport equipment and the road hazard detector 11.

[0084] As a further embodiment of the present invention, the control method of the controller comprises the following steps:

[0085] Obtaining distance change information between the two distance sensors 32 and the ground height;

[0086] When any distance change information is greater than the set value, the controller generates a forward stop information;

[0087] The forward driving of the two rear wheels 3 by the drive unit is stopped according to the forward stop information.

[0088] Working principle of the present invention:

[0089] A battery is installed on the mounting frame 1, a drive unit is installed on the rear wheel 3, and a steering unit is installed on the front wheel 2. Both the drive unit and the steering unit are installed with signal receivers and are controlled by a remote control unit. The inspector controls the rotation of the rear wheel 3 and the steering of the front wheel 2 through the remote control unit, so that the road disease detector 11 is close to the collapsed road while the inspector and the manned vehicle can stay away from the collapsed area, reducing the further expansion of the collapsed area and ensuring the safety of the inspector.

[0090] Before approaching the collapsed part of the road, the first electric cylinder 8 is operated to move the transmission shaft of the first electric cylinder 8 outward, and an external force is applied along the rotation connection of the rectangular rod 4, so that the two ends of the corresponding movable rod 5 rotate along the rotation connection respectively, so that the rectangular rod 4 and the corresponding mounting frame 1 are separated from each other;

[0091] When the rectangular rod 4 and the mounting frame 1 on one side of the movable rod 5 move away from each other, the two ends of the matching rod 7 on the same side rotate synchronously with the moving distance between the rectangular rod 4 and the mounting frame 1, and in the process of rotating the matching rod 7, the sliding block 6 is driven to slide along the sliding connection of the rectangular rod 4, and the two ends of the matching rod 7 on the other side are driven to rotate synchronously, so that the two mounting frames 1 move away from the rectangular rod 4 synchronously, and the rectangular rod 4 is always located at the center position of the two mounting frames 1. When the two mounting frames 1 move away from each other, the distance between the two rear wheels 3 increases, and at the same time, the distance between the two front wheels 2 increases, so that the transport device can adjust the wheel spacing on both sides according to the size of the pothole at the collapsed position, so that the transport device can move over the collapsed position and drive the road disease detector 11 to perform intuitive scanning and detection of the inside of the pothole formed by the collapse, thereby improving the efficiency of data collection on the cause of the accident;

[0092] After the collapsed road detection is completed, the two mounting frames 1 are moved closer to each other by the reverse movement of the transmission shaft of the first electric cylinder 8, thereby reducing the degree of road occupancy and preventing the road disease detector 11 from affecting the traffic in other lanes during normal road detection.

[0093] During the process of the two mounting frames 1 moving away from each other, the rotation direction of the two rear wheels 3 and the moving direction of the mounting frames 1 always remain perpendicular. As a result, when the two rear wheels 3 move away from each other, the contact points between the rear wheels 3 and the ground are prone to significant wear and tear, and the resistance of the mounting frames 1 moving away is increased. By cooperating with the load-bearing components, the auxiliary wheels 10 are driven to descend and contact the ground, so that the front wheels 2 and the rear wheels 3 are suspended. Since the auxiliary wheels 10 are parallel to the moving direction of the mounting frames 1, when the two mounting frames 1 move away from each other, the auxiliary wheels 10 roll in contact with the ground, reducing the resistance of the mounting frames 1 moving away and preventing wear of the front wheels 2 and the rear wheels 3 when they move.
