[0002] The core function of road disease detection equipment is to efficiently, accurately, and automatically identify and evaluate various damages and potential structural problems on the road surface. Road disease detection equipment mainly relies on sensors such as cameras, lasers, and radars to collect road surface information data, and converts road condition information into objective, standard, and digital asset data.

[0003] The patent document with the publication number CN115575947A discloses a road disease detection device, including a vehicle body and a lifting system, a hanging rack, and a ground penetrating radar system arranged on the vehicle body; the lifting system includes a mounting frame, a sliding frame, and a driving mechanism; the mounting frame is arranged on the vehicle body; the sliding frame is slidably arranged on the mounting frame for vertical sliding; the driving mechanism is arranged on the mounting frame, and the driving mechanism is connected to the sliding frame for driving the sliding frame to slide vertically.

[0004] When the existing road disease detection device detects the road, it usually uses an automobile as a power source to drive the road disease detection device to move for detection. When investigating and detecting the cause of a road that has collapsed, the approach of a heavier automobile is likely to cause further expansion of the collapsed position, thereby increasing economic losses and endangering the safety of the investigation and detection personnel. Moreover, when detecting a collapsed road, the detection equipment can usually only scan the surrounding area of the collapsed position and it is difficult to directly scan and detect the hole formed by the collapse, thus reducing the detection efficiency and affecting the data collection efficiency of the accident cause.

The transmission shaft of the second electric cylinder penetrates through the rectangular rod and extends to the lower part of the rectangular rod and is then fixedly connected to the limiting housing.

[0008] Preferably, an anti-slip frame is slidably connected inside the limiting housing. The bottom surface of the anti-slip frame is provided with anti-slip lines and is located below the auxiliary wheels. A plurality of springs are arranged inside the limiting housing, and the springs are fixedly connected between the limiting housing and the anti-slip frame.

[0009] Preferably, the positioning assembly includes: Two fixing frames are both arranged on the top of the strip-shaped frame; Two sliders are both slidably connected to the strip-shaped frame. The fixing frames are fixedly connected to the tops of the corresponding sliders. The road disease detector is fixedly installed on one of the fixing frames, and a counterweight is fixedly installed on the other fixing frame. A driving assembly is arranged between the two sliders, and the driving assembly is used to drive the two sliders to move away from each other.

[0010] Preferably, the driving assembly includes: A bidirectional lead screw is rotatably connected inside the strip-shaped frame. A motor is fixedly installed on the strip-shaped frame, and the output shaft of the motor is fixedly connected to one end of the bidirectional lead screw; Two connecting blocks are respectively fixedly connected to the bottoms of the two sliders, and the two connecting blocks are both threadedly connected to the bidirectional lead screw.

[0011] Preferably, two mounting grooves are respectively opened on the upper and lower sides of the slider, and a plurality of contact rollers are rotatably connected inside the mounting grooves, and the contact rollers are all in contact with the strip-shaped frame.

[0012] Preferably, connecting pins are fixedly connected to both sides of the bar-shaped frame near one end of the road disease detector. Rotating brackets are rotatably connected to the connecting pins. A torsion spring is fixedly installed at the rotating connection between the rotating bracket and the connecting pin. A flipping assembly is connected to the rotating bracket. When the fixed frame moves along the bar-shaped frame, the flipping assembly drives the rotating bracket to rotate and support on the ground.

[0013] Preferably, the flipping assembly includes: Two circular pins, which are respectively fixedly connected to the tops of the two rotating brackets. The circular pins are both located on the top of the bar-shaped frame; Two guiding bars, which are fixedly connected to both sides of the corresponding fixed frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0017] 2. By cooperating with the load-bearing assembly to drive the auxiliary wheels to descend and contact the ground, the front wheels and the rear wheels are in a suspended state. Since the auxiliary wheels are parallel to the moving direction of the mounting frame, when the two mounting frames move away from each other, the auxiliary wheels roll on the ground in contact, reducing the resistance when the mounting frames move away and preventing wear generated when the front wheels and the rear wheels move.

[0018] 3. When the two mounting brackets move away from each other, the anti-slip lines at the bottom of the anti-slip frame prevent the anti-slip frame from sliding, and through elastic extrusion, the anti-slip frame makes contact friction with the ground, so that the contact position between the anti-slip frame and the ground is the center point. The two mounting brackets move away from each other along the contact position between the anti-slip frame and the ground. Therefore, when the two mounting brackets move away from each other, the road disease detector does not move relative to the ground, reducing the center point offset generated when the two mounting brackets move away from each other, and eliminating the need for readjusting the position of the road disease detector.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art.

[0022] As Figures 1 to 9 shown, a transport device for a road disease detection device includes two mounting frames 1. On one side of the two mounting frames 1 away from each other, a front wheel 2 and a rear wheel 3 are installed. It further includes: A rectangular rod 4 is disposed between the two mounting frames 1. On both sides of the rectangular rod 4, a plurality of movable rods 5 are rotatably connected (as Figure 5 and Figure 6 shown). One end of the movable rod 5 is rotatably connected to the corresponding mounting frame 1; A sliding block 6 is slidably connected to the rectangular rod 4. On both sides of the sliding block 6, a mating rod 7 is rotatably connected. One end of the mating rod 7 is rotatably connected to the corresponding mounting frame 1; A 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; Two mounting strips 9 are respectively located at the bottoms of the two mounting frames 1. At the bottoms of the mounting strips 9, a plurality of auxiliary wheels 10 are rotatably connected. The axes of the auxiliary wheels 10 and the rear wheels 3 are perpendicular to each other. A mating load-bearing assembly is connected to the mounting strips 9; A road disease detector 11 is disposed above one end of the rectangular rod 4. A positioning assembly is connected between the road disease detector 11 and the rectangular rod 4; A strip-shaped frame (15) is fixedly connected to the top of the rectangular rod (4). A driving unit is installed on the rear wheel (3); A storage battery is installed on the mounting frame 1. A driving unit is installed on the rear wheel 3, and a steering unit is installed on the front wheel 2. Signal receivers are installed on both the driving unit and the steering unit, and they are controlled by a remote control unit. The detection personnel control the rotation of the rear wheel 3 and the steering of the front wheel 2 through the remote control unit, so that while the road disease detector 11 approaches the sunken road, the detection personnel and the manned vehicle can stay away from the sunken area, reduce the further expansion of the sunken area, and ensure the safety of the detection personnel; Before approaching the sunken area of the road, by operating the first electric cylinder 8, the transmission shaft of the first electric cylinder 8 moves outwards, 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 in cooperation along the rotation connection respectively, so that the rectangular rod 4 and the corresponding mounting frame 1 move away from each other; When the rectangular rod 4 moves away from the mounting frame 1 on one side of the movable rod 5, the two ends of the mating rod 7 on the same side rotate synchronously with the movement of the rectangular rod 4 and the mounting frame 1 away from each other. During the rotation of the mating rod 7, the slider 6 is driven to slide along the sliding connection of the rectangular rod 4, and the two ends of the mating 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 between 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, enabling the transportation device to adjust the wheel spacing on both sides according to the size of the pothole at the collapse position, allowing the transportation device to move through above the collapse position, and driving the road disease detector 11 to conduct an intuitive scanning detection of the interior of the pothole formed by the collapse, thereby improving the data collection efficiency of the accident cause; After the detection of the collapsed road is completed, the transmission shaft of the first electric cylinder 8 moves in the reverse direction to make the two mounting frames 1 approach each other, thereby reducing the degree of occupation of the road and preventing the influence of the road disease detector 11 on the traffic of other lanes during normal road detection.

[0023] 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. Therefore, when the two rear wheels 3 move away from each other, the contact position between the rear wheels 3 and the ground is prone to large wear, and the resistance when the mounting frames 1 move away increases. The auxiliary wheels 10 are driven to descend and contact the ground through the cooperating load-bearing assembly, so that the front wheels 2 and the rear wheels 3 are in a suspended state. 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 on the ground in contact, reducing the resistance when the mounting frames 1 move away and preventing the wear generated when the front wheels 2 and the rear wheels 3 move.

[0024] As a further embodiment of the present invention, the cooperating load-bearing assembly includes: 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 all slidably inserted into the corresponding mounting strips 9. A plurality of second limit pins 14 are fixedly connected to the tops of the mounting strips 9. The second limit pins 14 are all slidably inserted into the corresponding mounting frames 1; A second electric cylinder 16 is fixedly installed on the top of the strip-shaped frame 15. The transmission shaft of the second electric cylinder 16 penetrates through the rectangular rod 4 and extends below the rectangular rod 4 and is fixedly connected to the limit housing 12; When the second electric cylinder 16 works, the transmission shaft of the second electric cylinder 16 moves vertically downward, driving the limit housing 12 to move downward synchronously. Through the sliding connection between the first limit pin 13 and the mounting strip 9 of the limit housing 12, the mounting strip 9 moves vertically downward, driving the second limit pin 14 to move along the sliding insertion part of the mounting frame 1. When the auxiliary wheel 10 at the bottom of the mounting strip 9 contacts the ground and continues to move downward, the auxiliary wheel 10 replaces the front wheels 2 and the rear wheels 3 in contacting the ground, making the front wheels 2 and the rear wheels 3 in a suspended state. And when the two mounting frames 1 move away from each other, the mounting strip 9 moves synchronously with the corresponding mounting frame 1 through the sliding insertion of the second limit pin 14 into the mounting frame 1, so that the auxiliary wheel 10 at the bottom of the mounting strip 9 rolls along the moving direction of the mounting frame 1, reducing the frictional resistance generated when the two mounting frames 1 move away from each other and preventing the contact wear caused by the inconsistent rotation direction and moving direction of the front wheels 2 and the rear wheels 3.

[0025] As a further embodiment of the present invention, an anti-slip frame 17 is slidably connected inside the limit housing 12. The bottom surface of the anti-slip frame 17 is provided with anti-slip lines and is located below the auxiliary wheel 10. A plurality of springs 18 are arranged inside the limit housing 12. The springs 18 are fixedly connected between the limit housing 12 and the anti-slip frame 17. When the limit housing 12 drives the mounting strips 9 on both sides to move downward, the bottom of the anti-slip frame 17 contacts the ground prior to the auxiliary wheel 10. During the process of the auxiliary wheel 10 contacting the ground, the anti-slip frame 17 moves into the limit housing 12 under the load-bearing effect and compresses the springs 18 to produce a compressive deformation. Thus, when the auxiliary wheel 10 contacts the ground, the anti-slip frame 17 contacts the ground synchronously through the elastic extrusion of the springs 18. When the two mounting frames 1 move away from each other, the anti-slip lines at the bottom of the anti-slip frame 17 prevent the anti-slip frame 17 from sliding, and the elastic extrusion makes the anti-slip frame 17 generate a contact frictional force with the ground, so that the contact position of the anti-slip frame 17 with the ground is the center point. The two mounting frames 1 move away from each other along the contact position of the anti-slip frame 17 with the ground. Thus, when the two mounting frames 1 move away from each other, the road disease detector 11 does not move relative to the ground, reducing the center point offset generated when the two mounting frames 1 move away from each other and eliminating the need to readjust the position of the road disease detector 11.

[0026] As a further embodiment of the present invention, the positioning assembly includes: Two fixing frames 19 (as Figure 2 shown), and both of the two fixing frames 19 are arranged on the top of the strip-shaped frame 15. Two sliders 20, both of the two sliders 20 are slidably connected to the strip-shaped frame 15, the fixing frame 19 is fixedly connected to the top of the corresponding slider 20, the road disease detector 11 is fixedly installed on one of the fixing frames 19, and a counterweight 21 is fixedly installed on the other fixing frame 19. A driving component is arranged between the two sliders 20, and the driving component is used to drive the two sliders 20 to move away from each other; When the pothole formed by the road collapse is too large and the two mounting frames 1 cannot pass through even when moving away from each other to the maximum distance, the detection personnel drive the mounting frame 1 to move around the pothole formed by the road collapse through the remote control unit, and drive the two sliders 20 to move away from each other along the sliding connection of the strip-shaped frame 15 through the action of the driving component. The fixing frame 19 installed with the road disease detector 11 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. During the process of the road disease detector 11 approaching the pothole, the other fixing frame 19 drives the counterweight 21 to move in the opposite direction, thereby reducing the center of gravity offset generated during 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 up and fall into the pothole.

[0027] As a further embodiment of the present invention, the driving component includes: A bidirectional lead screw 22 (as Figure 8 shown), the bidirectional lead screw 22 is rotatably connected inside the strip-shaped frame 15, and a motor 23 is fixedly installed on the strip-shaped frame 15. The output shaft of the motor 23 is fixedly connected to one end of the bidirectional lead screw 22; Two connecting blocks 24, the two connecting blocks 24 are respectively fixedly connected to the bottoms of the two sliders 20, and the two connecting blocks 24 are both threadedly connected to the bidirectional lead screw 22; A signal receiver is installed on the motor 23 and is controlled by the remote control unit. The detection personnel remotely control the rotation of the output shaft of the motor 23 through the remote control unit, and drive the bidirectional lead screw 22 to rotate synchronously. Through the threaded connection of the bidirectional lead screw 22 to the two connecting blocks 24, the two sliders 20 move away from each other along the sliding connection of the strip-shaped frame 15, and drive the road disease detector 11 to move towards the pothole.

[0028] As a further embodiment of the present invention, two mounting grooves 25 are opened on both 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 all in contact with the strip-shaped frame 15; Through the contact of the contact rollers 26 inside the mounting groove 25 with the strip-shaped frame 15, when the slider 20 moves along the strip-shaped frame 15, the contact rollers 26 rotate in cooperation at the contact position of the strip-shaped frame 15, thereby reducing the frictional resistance generated during the movement and improving the movement smoothness of the slider 20 during the load-bearing process.

[0029] As a further embodiment of the present invention, connection pins 27 are fixedly connected to both sides of one end of the bar-shaped frame 15 close to the road disease detector 11. Rotating brackets 28 are rotatably connected to the connection pins 27. A torsion spring 29 is fixedly installed at the rotating connection of the rotating bracket 28 and the connection pin 27. A flipping assembly is connected to the rotating bracket 28. When the fixed frame 19 moves along the bar-shaped frame 15, the flipping assembly drives the rotating bracket 28 to rotate and support on the ground; When the fixed frame 19 drives the road disease detector 11 to move along the sliding connection of the bar-shaped frame 15, the flipping assembly drives the rotating bracket 28 to flip along the rotating connection of the connection pin 27, so that one end of the rotating bracket 28 is inclined to support on the ground at the edge of the pothole. When the road disease detector 11 approaches the center above the pothole, the rotating bracket 28 supports one end of the transport device close to the pothole, further improving the stability of the transport device and preventing the transport device from tipping up.

[0030] As a further embodiment of the present invention, the flipping assembly includes: Two circular pins 30 are respectively fixedly connected to the tops of the two rotating brackets 28. The circular pins 30 are both located on the top of the bar-shaped frame 15; Two guiding bars 31 are fixedly connected to both sides of the corresponding fixed frame 19 (as shown in Figure 2 ), and the ends of the guiding bars 31 (as shown in Figure 9 ) close to the circular pins 30 are provided with guiding inclined surfaces; When the road disease detector 11 moves along with the corresponding fixed frame 19, the guiding bars 31 on both sides of the fixed frame 19 approach the corresponding circular pins 30. Through the contact extrusion between the guiding inclined surfaces and the circular pins 30, the circular pins 30 move to the tops of the guiding bars 31. At the same time, the rotating bracket 28 flips along the rotating connection of the connection pin 27, and drives the torsion spring 29 to twist, so that the bottom end of the rotating bracket 28 supports on the ground after flipping. When the road disease detector 11 returns to the initial position along with the corresponding fixed frame 19, the circular pins 30 lose the guiding effect of the guiding bars 31 and return to the normal position through the torsion of the torsion spring 29, so that the bottom end of the rotating bracket 28 flips upward and retracts, reducing the influence on the movement of the transport device.

[0031] As a further embodiment of the present invention, distance sensors 32 (as shown in Figure 1 and Figure 5 ) are fixedly installed on both mounting frames 1. The distance sensors 32 are respectively located at the corresponding front wheels 2. A controller is connected between the drive unit for driving the rear wheels 3 to rotate and the two distance sensors 32; 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 for height. When the monitored ground height at any moving position of the front wheel 2 reaches the maximum value, the controller connected to the distance sensor 32 simultaneously stops the driving unit from driving the two rear wheels 3, preventing the detection personnel from accidentally operating through the remote control unit and causing the transportation equipment to fall into a pothole, and ensuring the safety of the transportation equipment and the road disease detector 11.

[0032] As a further implementation of the present invention, the control method of the controller includes the following steps: Obtain the distance change information between the two distance sensors 32 and the ground height; When any distance change information is greater than the set value, the controller generates a forward stop message; Stop the forward drive of the driving unit for the two rear wheels 3 according to the forward stop message.

[0033] The working principle of the present invention: A storage battery is installed on the mounting frame 1, a driving unit is installed on the rear wheel 3, a steering unit is installed on the front wheel 2, signal receivers are installed on both the driving unit and the steering unit, and they are controlled by a remote control unit. The detection personnel control the rotation of the rear wheel 3 and the steering of the front wheel 2 through the remote control unit, so that while the road disease detector 11 approaches the collapsed road, the detection personnel and the manned vehicle can stay away from the collapsed area, reduce the further expansion of the collapsed area, and ensure the safety of the detection personnel; Before approaching the collapsed area of the road, the first electric cylinder 8 works, so that the transmission shaft of the first electric cylinder 8 moves outwards, 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 respectively rotate in cooperation along the rotation connection, so that the rectangular rod 4 and the corresponding mounting frame 1 move away from each other; When the mounting frame 1 on one side of the rectangular rod 4 and the movable rod 5 moves away from each other, the two ends of the matching rod 7 on the same side rotate in cooperation synchronously as the rectangular rod 4 and the mounting frame 1 move away. And during the rotation of 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 in cooperation 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, the distance between the two rear wheels 3 increases, and at the same time the distance between the two front wheels 2 increases, enabling the transportation device to adjust the wheel spacing on both sides according to the size of the pothole at the collapsed position, enabling the transportation device to move through above the collapsed position, and driving the road disease detector 11 to conduct an intuitive scanning detection on the inside of the pothole formed by the collapse, thereby improving the data collection efficiency of the accident cause; After the detection of the sunken road is completed, the transmission shafts of the first electric cylinders 8 move in the reverse direction to make the two mounting brackets 1 approach each other, thereby reducing the degree of occupation of the road and preventing the impact on the traffic of other lanes during the normal road detection by the road disease detector 11.

[0034] During the process of the two mounting brackets 1 moving away from each other, the rotation directions of the two rear wheels 3 and the moving direction of the mounting brackets 1 always remain perpendicular. Therefore, when the two rear wheels 3 move away from each other, the contact positions of the rear wheels 3 with the ground are prone to significant wear, and the resistance during the movement of the mounting brackets 1 away is increased. By cooperating with the load-bearing assembly to drive the auxiliary wheels 10 to descend and contact the ground, the front wheels 2 and the rear wheels 3 are in a suspended state. Since the auxiliary wheels 10 are parallel to the moving direction of the mounting brackets 1, when the two mounting brackets 1 move away from each other, the auxiliary wheels 10 roll on the ground in contact, reducing the resistance during the movement of the mounting brackets 1 away and preventing the wear generated when the front wheels 2 and the rear wheels 3 move.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
