Description

Technical Field

[0001] This application relates to the technical field of highway inspection, and in particular to an unmanned highway inspection robot. Background Technology

[0002] Road maintenance is crucial for ensuring traffic safety, and highway inspection is a vital component. Highway inspection mainly includes checking for road surface damage, cracks, potholes, and other defects; roadbed defects such as gaps, settlement, and landslides; debris, snow accumulation, and other obstacles that could affect traffic safety; and the integrity of protective facilities such as guardrails, crash barriers, and medians. Through highway inspection, road defects and safety hazards can be identified and addressed, accidents can be prevented, and the safe operation of highways can be ensured.

[0003] There are two types of inspection methods: manual and automated. Manual inspection is more dangerous, and to ensure the safety of operators, automated equipment inspection is gradually replacing manual inspection.

[0004] There are currently two types of equipment inspection: fixed-point inspection and mobile inspection. Fixed-point inspection involves placing fixed detection probes at certain locations to inspect a section of the highway. This method has a relatively fixed detection range and is prone to missing some items.

[0005] Mobile inspection refers to equipment that can move along highways, thereby increasing the overall inspection range. Mobile inspection is generally divided into two types: track-based and trackless. Track-based inspection is exemplified by patent CN110497379B, which discloses a highway inspection robot, including a traveling device, a limiting device, a power generation device, and an inspection device. The limiting device, power generation device, and inspection device are all mounted on the traveling device. The traveling device is used for the movement of the inspection robot. The limiting device is used to mount the inspection robot on the corrugated guardrail of the highway. The power generation device is used to power the inspection robot. The inspection device is used for detection, monitoring, and warning. The traveling device includes at least two traveling mechanisms. The traveling mechanisms are flexibly connected by pins. Each traveling mechanism includes a traveling motor, a walking frame, rollers, a first pulley, a second pulley, a driven shaft, a synchronous belt, and a drive shaft.

[0006] For example, patent CN116352675A discloses a trackless self-propelled intelligent inspection robot for highway tunnels. It includes a chassis frame, a fixed base on the top of the chassis frame, a support rod fixedly mounted on one side of the fixed base, a mounting base fixedly mounted on the top of the support rod, and a fixed protective box hinged inside the mounting base. A turntable is rotatably mounted on the top of the chassis frame, and a cylinder is fixedly mounted on the top of the turntable. A telescopic wall is mounted on the output end of the cylinder, and a hinged sleeve is hinged to the end of the telescopic wall away from the cylinder. When started by a transmission motor, the output end of the transmission motor can drive the rotating shaft to rotate, thereby rotating the wheel, causing the tire to move on the outside of the wheel, thus moving the device and allowing the robot to perform mobile inspections inside the tunnel.

[0007] Compared to trackless systems, track-based inspection systems have limited movement paths. Furthermore, to save costs, highway guardrails are often used as tracks. However, the shape of guardrails varies across different highway sections, and deformation due to erosion or other factors can significantly restrict the equipment's movement, thus affecting inspections. On the other hand, track-based inspections have advantages such as not occupying lanes, higher safety, and less susceptibility to vehicle collisions.

[0008] Trackless inspection has a more flexible walking path and can inspect more locations and areas. However, it has the disadvantage of occupying a lane and being prone to collisions with vehicles due to its small size, which could lead to accidents and lower safety. Summary of the Invention

[0009] To improve safety, this application provides an unmanned highway inspection robot.

[0010] The unmanned highway inspection robot provided in this application adopts the following technical solution:

[0011] An unmanned highway inspection robot includes a vehicle body equipped with inspection probes. The vehicle body includes a hollow frame, which comprises a front end and a body. The frame has several aerodynamic plates coated with a reflective coating. Each aerodynamic plate includes a wind-conducting plate at the end of the body and wind-following plates on both sides of the frame. The wind-following plate is hinged to the frame at one end facing the front end and connected to the frame at the other end via a micro-motion spring. The wind-following plate is wavy. The wind-conducting plate includes a left plate and a right plate, which are coated with a reflective coating to form left-pointing and right-pointing arrows, respectively.

[0012] By adopting the above technical solution, the inspection probes patrol the highway while the vehicle is in motion. The airflow generated during vehicle movement spreads throughout the entire vehicle body via the perforated frame. When the airflow hits the wind vane, the pressure of the airflow compresses the micro-spring, causing the wind vane to vibrate continuously. The reflective coating on the wind vane reflects sunlight or vehicle headlights, and the light emitted by the vibrating wind vane creates a flashing effect, thus alerting vehicles. The left and right arrows on the wind vane also alert vehicles to avoid collisions. Through the wind vane design, the vehicle body can automatically generate a flashing effect, alerting passing vehicles, preventing collisions, and improving safety. Furthermore, the flashing effect does not require additional power, reducing energy consumption and increasing the vehicle's patrol endurance.

[0013] Preferably, the front and body of the vehicle are provided with a number of air passage holes, and an air passage ring is rotatably connected in the air passage hole. The inner ring of the air passage ring is provided with a number of air passage plates at an incline. The air passage plates are horizontally slidably connected to the frame. Two air passage rings are respectively connected to the left plate and the right plate through connecting rods. One end of the connecting rod is hinged to the air passage ring, and the other end is hinged to the air passage plate.

[0014] By adopting the above technical solution, during vehicle movement, airflow passes through the air vents. When the airflow passes through the air vent ring, the air vent vanes are disturbed by the airflow, causing the air vent ring to rotate. The air vent ring drives the left and right vanes to move back and forth via connecting rods, creating a dynamic visual effect, thereby further reminding the vehicle.

[0015] Preferably, the vehicle front includes a front frame and a buffer frame. The front frame is fixedly connected to the vehicle body. Two buffer frames are provided and located on both sides of the front frame. One end of each buffer frame is connected to the front frame, and the other end is connected to the front wheel via a wheel bracket. The wheel bracket is connected to the buffer frame via a universal joint. A reversing rod located between the two buffer frames is rotatably connected to the front frame. A drive device for driving the reversing rod to rotate is installed on the front frame. The drive device is connected to the middle part of the reversing rod. Each end of the reversing rod is hinged with a connecting rod 1. The two connecting rod 1s control the two front wheels respectively. The end of the connecting rod 1 away from the reversing rod is connected to a connecting rod 2 via a universal joint. The end of the connecting rod 2 away from the connecting rod 1 is connected to the wheel bracket via a universal joint.

[0016] By adopting the above technical solution, the drive device drives the directional rod to rotate, and the directional rod drives the wheel frame to rotate through connecting rod one and connecting rod two. The two wheel frames rotate in the same direction at the same time, thereby realizing the steering of the vehicle body.

[0017] Preferably, front buffers are provided on both sides of the front frame, with one end of the front buffer hinged to the front frame and the other end tilted downwards and hinged to the buffer frame.

[0018] By adopting the above technical solution, when the vehicle body is moving and bumps occur, the front buffer absorbs and buffers the impact force on the buffer frame, thereby ensuring the overall stability of the front frame.

[0019] Preferably, the vehicle body is provided with a walking frame on both sides, and a number of walking wheels are provided on the walking frame. The walking wheels are arranged in a circumferential direction, and the walking frame is provided with a walking track, which covers all the walking wheels.

[0020] By adopting the above technical solution, the vehicle body moves by means of tracks, which can improve the grip of the vehicle body during movement, thereby improving the overall stability of the vehicle body and reducing the impact of external wind on the stability of the vehicle body.

[0021] Preferably, the traveling wheel includes two upper wheels and two lower wheels. A lower frame for supporting the lower wheels is hinged to the traveling frame. One end of the lower frame is hinged to the traveling frame and the other end is connected to the lower wheel. A rear buffer connected to the lower frame is provided on the traveling frame. One end of the rear buffer is hinged to the traveling frame and the other end is hinged to the lower frame.

[0022] By adopting the above technical solution, the lower wheel contacts the road surface through the walking track. When the road surface is uneven and bumps occur, the lower wheel transmits the vibration force generated by the bump to the rear buffer. The rear buffer absorbs and weakens the vibration force, thereby ensuring the overall stability of the vehicle body.

[0023] Preferably, the upper wheel includes a driving wheel and a driven wheel, and the outer wall of the driving wheel is evenly provided with a plurality of driving grooves.

[0024] By adopting the above technical solution, the drive wheel increases the friction between itself and the track through the drive groove, thereby driving the track to rotate and achieving movement.

[0025] Preferably, a drive motor is mounted on the frame, and the drive motor is connected to a drive shaft through a reduction gearbox, with two drive wheels respectively mounted at both ends of the drive shaft.

[0026] By adopting the above technical solution, the drive motor synchronously drives two drive wheels to rotate through a single drive shaft, making it convenient to use.

[0027] Preferably, the walking frame is provided with two tensioning frames, and a tensioning wheel located above the lower wheel is rotatably connected to the tensioning frame. The walking track passes around the tensioning wheel, and the two tensioning frames are respectively connected to the two lower frames. The end of the tensioning frame away from the tensioning wheel is fixedly connected to the end of the lower frame that is hinged to the walking frame.

[0028] By adopting the above technical solution, the lower wheel moves up and down when bumping, and when the lower wheel moves upward, the lower frame rotates counterclockwise around its upper end. The lower frame synchronously drives the tensioning frame to rotate counterclockwise, at which point the tensioning wheel moves upward synchronously, causing it to arch the track between the two upper wheels. When the lower wheel moves upward, it temporarily separates from the track, resulting in a weakening of the track tension and making it prone to slippage. The tensioning wheel, however, moves synchronously with the lower wheel through the tensioning frame. When the lower wheel moves upward, the tensioning wheel moves upward synchronously, thus maintaining track tension at all times, ensuring proper track movement, and preventing slippage.

[0029] Preferably, the vehicle frame is provided with a buffer plate, and a number of buffer springs are provided between the buffer plate and the vehicle frame. The inspection probe is installed on the buffer plate, and a buzzer is installed on the vehicle frame.

[0030] By employing the above technical solution, the buffer plate and buffer spring cushion the inspection probe, ensuring its stability during image capture. The buzzer and the fan plate work together to alert the vehicle using both sound and light, thereby improving safety.

[0031] In summary, this application includes the following beneficial technical effects:

[0032] By incorporating a wind-driven plate, the airflow exerts pressure on the plate during vehicle movement, along with the vehicle's own vibrations, causing the plate to vibrate continuously. The reflected light from the plate produces a near-flickering effect, thus alerting other vehicles and preventing collisions, thereby improving safety. Attached Figure Description

Detailed Implementation

[0044] The present application will be further described in detail below with reference to all the accompanying drawings.

[0045] Example

[0046] This application discloses an unmanned highway inspection robot, referring to... Figure 1 It includes a vehicle body 1, an inspection probe 2, a buzzer, a controller, and a remote controller. The vehicle body 1 includes a hollow frame 3, and the airflow generated during the formation of the vehicle body 1 will spread along the frame 3.

[0047] Reference Figure 1 and Figure 2 The frame 3 includes a front end 31 and a body 32. The front end 31 includes a front frame 311 and a buffer frame 312. The front frame 311 is fixedly connected to the body 32, and there are two buffer frames 312, which are movably connected to both sides of the front frame 311.

[0048] Reference Figure 1 and Figure 2One end of the buffer frame 312 is hinged to the front frame 311 via a horizontal pivot, and the other end is connected to the front wheel 314 via a wheel frame 313. Front buffers 319 are provided on both sides of the front frame 311. One end of the front buffer 319 is hinged to the front frame 311, and the other end is tilted downwards and hinged to the buffer frame 312. When the front wheel 314 experiences up-and-down bumps during operation, the buffer frame 312 can swing up and down, and the front buffer 319 absorbs and weakens the vibration force of the front wheel 314, thereby buffering the vibration and improving the overall stability of the vehicle body 1.

[0049] Reference Figures 1 to 3 The wheel frame 313 and the buffer frame 312 are connected by a universal joint, which ensures the free rotation of the wheel frame 313 and enables reversing. A reversing rod 315 located between the two buffer frames 312 is rotatably connected to the front frame 311, and the reversing rod 315 is horizontally positioned. A drive device 316 for driving the reversing rod 315 to rotate is installed on the front frame 311. The drive device 316 can be a motor. The output shaft of the drive device 316 is vertical and fixedly connected to the middle part of the reversing rod 315. Connecting rods 317 are hinged to both ends of the reversing rod 315. The two connecting rods 317 control the two front wheels 314 respectively. The end of the connecting rod 317 away from the reversing rod 315 is connected to a connecting rod 318 via a universal joint. The end of the connecting rod 318 away from the connecting rod 317 is connected to the wheel frame 313 via a universal joint.

[0050] Reference Figures 1 to 3 The drive unit 316 is electrically connected to the controller, and the controller is electrically connected to the remote controller. The operator can control the drive unit 316 via the remote controller to change the direction of travel of the vehicle body 1. When the drive unit 316 starts, the reversing lever 315 rotates. When the reversing lever 315 rotates clockwise or counterclockwise, the two connecting rods 317 rotate in the same direction, and through the connecting rod 318, drive the wheel frame 313 to rotate, thereby causing the two wheel frames 313 to rotate synchronously clockwise or counterclockwise, thus achieving reversing.

[0051] Reference Figure 1 and Figure 4 A buffer plate 321 is vertically slidably connected to the vehicle body 32. Several buffer springs 322 are provided between the buffer plate 321 and the vehicle body 32. Protective side plates 323 are inclined on both sides of the buffer plate 321. The inspection probe 2 and the buzzer are installed on the buffer plate 321.

[0052] Reference Figure 4 and Figure 5 The vehicle body 32 has a traveling frame 34 fixed on both sides, and several traveling wheels 71 are provided on the traveling frame 34, arranged circumferentially on the traveling frame 34. A traveling track 72 rotates on the traveling frame 34, and the traveling track 72 covers all the traveling wheels 71. Vehicle body 1 (see...) Figure 1 The vehicle is driven by the walking track 72, which provides relatively stable movement.

[0053] Reference Figures 4 to 6 The track 71 includes two upper wheels 711 and two lower wheels 712. The two upper wheels 711 are respectively a driven wheel 7112 near the front of the vehicle 31 and a driving wheel 7111 away from the vehicle body 1. The outer wall of the driving wheel 7111 has several drive grooves 71111 evenly distributed around its circumference. A drive motor 61 electrically connected to the controller is installed at the bottom of the vehicle body 32. The drive motor 61 is connected to a horizontally arranged drive shaft 63 through a reduction gearbox 62. The two ends of the drive shaft 63 are located in two walking frames 34, and the two driving wheels 7111 are respectively installed at the two ends of the drive shaft 63. The drive motor 61 drives the drive shaft 63 to rotate through the reduction gearbox 62, and the drive shaft 63 drives the driving wheels 7111 to rotate, providing power for the forward movement of the track 72.

[0054] Reference Figures 4 to 6 A lower frame 35 for supporting the lower wheel 712 is hinged to the traveling frame 34. The upper end of the lower frame 35 is hinged to the traveling frame 34, and the lower wheel 712 is mounted on the lower end of the lower frame 35. A rear buffer 36 connected to the lower frame 35 is provided on the traveling frame 34. One end of the rear buffer 36 is hinged to the traveling frame 34, and the other end is hinged to the lower frame 35. During travel, the lower wheel 712 contacts the road surface through the traveling track 72. When the road surface is uneven and bumps occur, the lower wheel 712 is compressed and moves up and down. The lower frame 35 rotates around its upper end. The rear buffer 36 absorbs and eliminates the vibration force generated by the lower wheel 712, thereby improving the vehicle body 1 (see...). Figure 1 The stability of ).

[0055] Reference Figures 4 to 6 When the lower wheel 712 moves upwards on bumps, it will briefly disengage from the track 72. At this time, the lower end of the track 72 lacks support, which will weaken the tension of the track 72 and cause slippage. To ensure the traction of the track 72, the tension of the track 72 needs to be maintained at all times.

[0056] Reference Figures 4 to 6 The traveling frame 34 is equipped with two tensioning frames 37, which are connected to two lower frames 35 respectively. The lower end of the tensioning frame 37 and the lower frame 35 are fixedly connected to the hinged end of the traveling frame 34. That is, when the lower frame 35 rotates, it will drive the tensioning frame 37 to rotate synchronously.

[0057] Reference Figures 4 to 6The upper end of the tensioning frame 37 is rotatably connected to a tensioning wheel 73 located above the lower wheel 712, and the track 72 passes around the tensioning wheel 73. When the lower wheel 712 is at its lowest position, the upper end of the tensioning wheel 73 is flush with the upper end of the upper wheel 711. When the lower wheel 712 is lifted under pressure, the lower frame 35 drives the tensioning frame 37 to rotate downwards synchronously, and the tensioning wheel 73 moves upwards, arching the track 72, thereby ensuring the tension of the track 72.

[0058] Reference Figures 1 to 7 The frame 3 is equipped with several wind-driven plates 4, which are coated with a reflective coating. The wind-driven plates 4 reflect sunlight or vehicle headlights through the reflective coating, thereby alerting vehicles to take evasive action.

[0059] Reference Figure 1 , Figure 7 and Figure 8 The wind-driven plate 4 includes wind-following plates 42 located on both sides of the frame 3 and wind-conveying plates 41 located at the end of the body 32. The wind-following plates 42 are arranged in a wave shape. One end of the wind-following plate 42 facing the front of the vehicle 31 is hinged to the protective side plate 323, and the other end is connected to the protective side plate 323 through a micro-motion spring 43. The wind force generated by the vehicle body 1 during driving and its own vibration force cause the wind-following plate 42 to continuously compress the micro-motion spring 43, causing the wind-following plate 42 to vibrate continuously. The surface of the wind-following plate 42 flashes under the action of the reflective coating, thereby reminding the vehicle to move.

[0060] Reference Figure 1 , Figure 7 , Figure 8 and Figure 9 The air intake 41 includes a left 411 and a right 412. Left and right 411 and 412 are coated with reflective coatings to form left-pointing and right-pointing arrows, respectively. Several air passage holes 33 are provided at the ends of the vehicle front 31 and body 32. An air passage ring 5 is rotatably connected within each air passage hole 33. Several air passage plates 51 are inclinedly arranged within the inner ring of the air passage ring 5. The air intake 41 is horizontally slidably connected to the vehicle frame 3. Two of the air passage rings 5 ​​are connected to the left 411 and right 412 respectively via connecting rods 52. One end of the connecting rod 52 is hinged to the air passage ring 5, and the other end is hinged to the air intake 41.

[0061] Reference Figure 1 , Figure 7 , Figure 8 and Figure 9 During vehicle 1's movement, airflow passes through the air vents 33. When the airflow passes through the air vent ring 5, the air vent vanes 51 are disturbed by the airflow, causing the air vent ring 5 to rotate. The air vent ring 5 drives the left vane 411 and the right vane 412 to move back and forth via the connecting rod 52, creating a dynamic visual effect, thereby further reminding the vehicle.

[0062] The implementation principle of the highway unmanned inspection robot in this application embodiment is as follows: the operator controls the vehicle body 1 through a remote controller. The vehicle body 1 walks along the highway. The walking track 72 provides driving force for the vehicle body 1. The front frame changes the walking direction of the vehicle body 1. The inspection probe 2 inspects and takes pictures of the highway.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
