Description

Technical Field

[0001] This invention relates to the field of traffic control technology, and more particularly to intelligent traffic robots. Background Technology

[0002] In current road construction and maintenance scenarios, the placement of warning facilities such as traffic cones and guide boards mainly relies on manual operation: construction workers need to manually move and place traffic cones in sections with heavy traffic, which is not only labor-intensive and inefficient, but also poses a safety risk of traffic accidents; at the same time, the placement of traffic cones by hand depends on experience judgment, which is prone to problems such as uneven spacing and positional deviation, resulting in poor early warning and guidance effects.

[0003] Some existing technologies attempt to use mechanical devices to assist in placement, but these devices are mostly single-function and lack the ability to accurately perceive the on-site environment during actual operation. They may not be able to dynamically adjust the placement point according to the actual obstacles and lane width of the construction section, making it difficult to adapt to complex road maintenance scenarios. Therefore, an intelligent transportation robot with autonomous perception, precise operation, multi-scenario adaptability, and the ability to solve the shortcomings of traditional manual and single mechanical devices is particularly important. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by proposing an intelligent transportation robot.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The intelligent transportation robot includes a robot body with multiple antennas connected to it; and also includes:

[0007] The telescopic plate is slidably connected to the robot body.

[0008] The locking sleeve is fixedly connected to the telescopic plate;

[0009] A riser is fixedly connected to a locking sleeve. A mounting sleeve is detachably connected to the top of the riser. A first electric push rod is fixedly connected to the mounting sleeve. A clamping part is fixedly connected to the drive end of the first electric push rod. The clamping part is used to pick up and put down traffic cones and guide plates.

[0010] The display screen is detachably attached to the robot body.

[0011] The hangar, which houses the drone, is fixedly attached to the top of the display screen;

[0012] The drone is equipped with a camera and a positioning unit, which are used to fly to the construction and maintenance section, collect image data and real-time location data of the on-site construction scene, and transmit the image data and location data to the control module on the robot body.

[0013] The control module is used to calculate the target placement points of the traffic cones and guide plates based on the image data and location data transmitted by the UAV body, and control the sliding of the telescopic plate and the extension and retraction of the first electric push rod. The gripping part picks up the traffic cones or guide plates, and the robot body moves to accurately move the traffic cones or guide plates to the target placement points and complete the placement.

[0014] Preferably, two sets of symmetrically arranged second electric push rods are fixedly connected to the robot body, and a reinforcing plate is fixedly connected to the drive end of the second electric push rod. The reinforcing plate is fixedly connected to the telescopic plate.

[0015] Furthermore, a first limiting slide rail is fixedly connected to the robot body, and a first sliding plate is slidably connected to the first limiting slide rail. The first sliding plate is fixedly connected to the reinforcing plate.

[0016] Furthermore, a second limiting slide rail is fixedly connected to the reinforcing plate, a second sliding plate is slidably connected to the second limiting slide rail, and a lower pressure plate is fixedly connected to the bottom of the second sliding plate.

[0017] Furthermore, a third electric push rod is fixedly connected to the reinforcing plate, and a connecting block is fixedly connected to the drive end of the third electric push rod, the connecting block being fixedly connected to the second sliding plate.

[0018] Preferably, the clamping part includes symmetrically arranged limiting plates and clamping plates, with the two sets of limiting plates arranged on both sides of the clamping plate. The clamping plate is fixedly connected to the driving end of the first electric push rod. A first sliding groove is provided on the clamping plate, and a limiting clamping rod is slidably connected in the first sliding groove.

[0019] Furthermore, a second sliding groove is provided on the card plate, and a slider is slidably connected in the second sliding groove. The slider is fixedly connected to the limiting rod.

[0020] Furthermore, an electromagnet is fixedly connected in the second slide groove, the slider is an iron block, and the electromagnet is attracted to the slider.

[0021] Furthermore, a tension spring is fixedly connected to the slider, and the end of the tension spring away from the slider is fixedly connected to the inner wall of the second groove.

[0022] Furthermore, the card plate is equipped with a limit plate.

[0023] Compared with the prior art, the present invention provides an intelligent transportation robot, which has the following beneficial effects:

[0024] 1. This invention uses drones to automatically survey the site and robots to autonomously pick up and place traffic cones and guide boards, replacing manual work in dangerous road sections and effectively avoiding safety risks for construction workers. At the same time, the automated operation process of robots is more efficient than manual placement, thereby significantly shortening the construction preparation time.

[0025] 2. In this invention, the clamping part adopts a combination structure of electromagnet, limiting rod and tension spring.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Example 1:

[0041] Reference Figures 1-12 The intelligent transportation robot includes a robot body 1, on which multiple antennas 102 are connected; it also includes:

[0042] The telescopic plate 5 is slidably connected to the robot body 1;

[0043] Locking sleeve 501 is fixedly connected to telescopic plate 5;

[0047] Reference Figure 2 , Figure 3 In specific implementation, a mounting base 101 is fixedly connected to the robot body 1, a locking hook 1011 is fixedly connected to the mounting base 101, a mounting plate 202 is fixedly connected to the bottom side wall of the display screen 2, a clamp 2021 is connected to the mounting plate 202, and the clamp 2021 matches the locking hook 1011.

[0048] Reference Figure 3 In practice, the bottom of the display screen 2 is also connected to a retractable support leg 201; through the retractable support leg 201 connected to the bottom of the display screen 2, when the display screen 2 is removed from the robot body 1, the retractable support leg 201 can be opened and the robot can be erected directly for use.

[0049] The hangar 3, which includes the drone body 301, is fixedly connected to the top of the display screen 2;

[0050] Reference Figure 1 In practical implementation, the drone body 301 adopts a commercially available wireless drone. The positioning unit of the drone body 301 is a Beidou RTK positioning module with a positioning accuracy of ≤2cm. The drone and the control module achieve wireless communication through the 5G antenna 102 of the robot body 1, with a data transmission delay of ≤100ms. The flight path of the drone body 301 is pre-planned by the control module, covering the starting point of the construction section to the end point of the work area. When the remaining power is ≤20% or the signal strength is <-80dBm, it automatically returns to the hangar 3.

[0051] The drone body 301 is equipped with a data acquisition camera and a positioning unit, which is used to fly to the construction and maintenance section, collect image data and real-time location data of the on-site construction scene, and transmit the image data and location data to the control module on the robot body 1.

[0052] The control module is used to calculate the target placement points of the traffic cone 11 and the guide plate 12 based on the image data and position data transmitted by the UAV body 301, and control the sliding of the telescopic plate 5, the extension and retraction of the first electric push rod 6, the gripping part 7 to pick up the traffic cone 11 or the guide plate 12, and the robot body 1 to move the traffic cone 11 or the guide plate 12 to the target placement point and complete the placement.

[0053] In practical implementation, the control module adopts an embedded industrial control board equipped with an ARM Cortex-A72 processor. After the control module calculates the target point, the robot body 1 moves to a range of ±0.5m from the point. The robot body 1 collects on-site images through an auxiliary camera, and the position is calibrated twice to complete the placement. The final placement error is ≤0.1m.

[0054] Two sets of symmetrically arranged second electric push rods 8 are fixedly connected to the robot body 1. A reinforcing plate 502 is fixedly connected to the drive end of the second electric push rod 8, and the reinforcing plate 502 is fixedly connected to the telescopic plate 5.

[0055] A first limiting slide rail 10 is fixedly connected to the robot body 1, and a first sliding plate 9 is slidably connected to the first limiting slide rail 10. The first sliding plate 9 is fixedly connected to the reinforcing plate 502.

[0056] A second limiting slide rail 5021 is fixedly connected to the reinforcing plate 502, a second sliding plate 503 is slidably connected to the second limiting slide rail 5021, and a lower pressure plate 5031 is fixedly connected to the bottom of the second sliding plate 503.

[0057] A third electric push rod 504 is fixedly connected to the reinforcing plate 502. A connecting block 5041 is fixedly connected to the drive end of the third electric push rod 504. The connecting block 5041 is fixedly connected to the second slide plate 503.

[0058] The clamping part 7 includes a symmetrically arranged limiting plate 701 and a clamping plate 702. The two sets of limiting plates 701 are arranged on both sides of the clamping plate 702. The clamping plate 702 is fixedly connected to the driving end of the first electric push rod 6. A first sliding groove 703 is provided on the clamping plate 702, and a limiting clamping rod 7031 is slidably connected in the first sliding groove 703.

[0059] The card plate 702 has a second slide groove 707, and a slider 705 is slidably connected in the second slide groove 707. The slider 705 is fixedly connected to the limiting rod 7031.

[0060] An electromagnet 706 is fixedly connected in the second slide groove 707, and the slider 705 is an iron block. The electromagnet 706 and the slider 705 are attracted to each other.

[0061] Reference Figures 1-12 In practical use, the steps are as follows:

[0062] Start the robot body 1 and complete the system self-test; confirm that the display screen 2 is securely connected to the locking hook 1011 of the robot body 1 via the clamp 2021, and that the drone body 301 in the hangar 3 has sufficient power, and complete the initial configuration.

[0063] In actual operation, the control module pre-plans the flight path of the UAV body 301 based on the construction section information; the UAV body 301 takes off from the hangar 3, uses the Beidou RTK positioning module for real-time positioning, and simultaneously starts the acquisition camera to collect on-site image data; the UAV body 301 transmits image data and position data to the control module through the 5G antenna 102; based on the on-site data transmitted by the UAV and combined with the preset rule base, the control module calculates the target placement points of the road cone 11 and the guide plate 12, and generates the movement path of the robot body 1.

[0064] When the traffic cone 11 is picked up, the robot body 1 moves to the side of the loading vehicle where the traffic cone 11 is placed. The control module drives the second electric push rod 8 to extend and retract, causing the telescopic plate 5 to slide along the first limit slide rail 10 and adjust the horizontal position of the riser 4. The third electric push rod 504 starts to drive the lower pressure plate 5031 to move down. After the lower pressure plate 5031 moves down a certain distance, it will contact the ground. At this time, when the third electric push rod 504 pushes again, the overall height of the robot body 1 will increase. When it moves to a suitable height, the first electric push rod 6 extends and retracts, moving the gripping part 7 to directly above the traffic cone 11. The gripping part 7 descends, causing the clamping plate 702 to be inserted into the clamping hole above the traffic cone 11. The electromagnet 706 is energized, and the adsorption slider 705 slides along the second slide groove 707, simultaneously driving the limit clamping rod 7031 to clamp the inner wall of the clamping hole of the traffic cone 11 along the first slide groove 703, completing the fixed picking up of the traffic cone 11.

[0065] When the guide plate 12 is picked up, the robot body 1 moves to the side of the stand where the guide plate 12 is placed, and the control module adjusts the position of the gripping part 7 to above the guide plate 12; the gripping part 7 is pushed outward slightly so that the limiting roll plate 7021 on the clamping plate 702 extends into the recess on the back of the guide plate 12; the electromagnet 706 is energized to attract the top of the guide plate 12, and at this time the limiting roll plate 7021 assists in lifting the guide plate 12, thus completing the fixed picking up of the guide plate 12.

[0066] During placement, robot body 1 moves along a preset path until it reaches the target location within ±0.5m; the auxiliary camera of robot body 1 captures images of the site, and the control module performs secondary calibration of the position.

[0067] When placing the traffic cone 11: the third electric push rod 504 drives the lower pressure plate 5031 to descend. When the bottom of the traffic cone 11 is in contact with the ground, the electromagnet 706 is de-energized, the tension spring 704 drives the slider 705 to reset, and the limit rod 7031 is released. At this time, the limit rod 7031 no longer clamps the traffic cone 11, and the traffic cone 11 can be placed at the fixed point.

[0068] When placing the guide plate 12: the third electric push rod 504 drives the lower pressure plate 5031 to descend. When the bottom of the guide plate 12 is 5cm away from the ground, the electromagnet 706 is de-energized. At this time, the fixing and limiting attraction force of the clamping plate 702 disappears. Because the outer height of the clamping plate 702 is greater than the inner height, it falls clockwise, and the guide plate 12 is naturally lowered. The upright plate 1201 on the back of the guide plate 12 provides auxiliary support, completing the stable placement.

[0069] Once the traffic cone 11 or guide plate 12 is stably placed, the gripping part 7 resets, and the robot body 1 evacuates from the current position. The placement process is repeated until all traffic cones 11 and guide plates 12 are placed. Afterward, the robot body 1 returns to its initial position, the drone body 301 charges in hangar 3, and the equipment enters standby mode.

[0070] Reference Figure 12 In practice, the slider 705 can be set as a commercially available pure iron block.

[0071] A tension spring 704 is fixedly connected to the slider 705, and the end of the tension spring 704 away from the slider 705 is fixedly connected to the inner wall of the second slide groove 707.

[0072] Reference Figure 12 When the electromagnet 706 is de-energized, the slider 705 can be quickly reset by the tension spring 704.

[0073] A limit plate 7021 is provided on the card plate 702.

[0074] Reference Figure 9 , Figure 12 When the clamping part 7 takes the guide plate 12, the clamping part 7 can be pushed outward slightly. At this time, the limiting coil 7021 on the clamping plate 702 will extend into the back recess of the guide plate 12. When the electromagnet 706 attracts the top of the guide plate 12, the limiting coil 7021 can assist in lifting the guide plate 12, further improving the hoisting stability of the guide plate 12.

[0075] Reference Figure 9 In actual use, the back of the guide plate 12 is also fixedly connected to the upright plate 1201 via a connecting rod. When the electromagnet 706 is de-energized, the guide plate 12 will be lowered from the clamping part 7. At this time, since the outer height of the clamping plate 702 is greater than the inner height, the clamping plate 702 will fall clockwise. At this time, the upright plate 1201 on the back of the guide plate 12 can effectively and stably support the guide plate 12.
