Description

Technical Field

[0001] This utility model relates to the field of traffic safety facility automation technology, and in particular to an infrared GPS adaptive traffic cone deployment and retraction device. Background Technology

[0002] Road cones are common traffic safety facilities, also known as road sign cones, traffic cones, or warning cones. They are typically used to mark road construction sites or accident scenes, reminding drivers to slow down, detour, or be aware of dangerous areas. The main components of a road cone include a base, a cone body, and reflective material. The base is wide to ensure stable placement on the road surface and prevent tipping. The cone body is the main part, used to attract the attention of pedestrians and vehicles. The reflective material is distributed on the surface of the cone, reflecting light under illumination to enhance its warning effect. This design helps improve visibility, and because of the cone's stability, it is not easily collapsed in strong winds. Road cones also have a certain degree of flexibility to reduce injury to vehicles and pedestrians.

[0003] Currently, the placement and retrieval of traffic cones mainly rely on manual operation. Workers need to repeatedly bend over, which is not only labor-intensive and inefficient, but also prone to back injuries from prolonged bending. More seriously, manual operation must be carried out in open road environments, exposing workers to higher traffic safety risks. Regarding placement accuracy, manual operation struggles to ensure consistent cone spacing, affecting road aesthetics and potentially reducing warning effectiveness due to uneven spacing. While some mechanized traffic cone placement and retrieval devices exist, these generally suffer from insufficient positioning accuracy and poor adaptability, failing to achieve intelligent and precise cone placement and retrieval operations. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0041] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0042] In existing technologies, traffic cones, as traffic safety facilities, generally suffer from low efficiency in manual placement and retrieval. Workers need to repeatedly bend over to operate them, which is not only labor-intensive and time-consuming but also poses traffic safety hazards. Traditional manual operation makes it difficult to ensure consistent spacing between traffic cones, easily resulting in skewed placement and uneven spacing, affecting the road warning effect. Especially in expressway construction scenarios, the frequent movement of construction vehicles leads to a mismatch between the efficiency of manual placement and the construction progress, and the safety risks of workers exposed to the open traffic environment are particularly prominent.

[0043] To address the aforementioned issues, researchers observed that mechanized operation could effectively reduce manual labor intensity, but existing mechanical equipment suffered from insufficient positioning accuracy and poor adaptability. Repeated experiments revealed that simple mechanical conveying devices could not solve the problem of traffic cone attitude control, while a single sensor system was insufficient to meet the precise positioning requirements in dynamic environments. Analysis of the construction vehicle's trajectory showed that lateral position adjustment capability was a key element in achieving linear arrangement of traffic cones. Ultimately, it was determined that spatial positioning technology, a multi-stage guiding mechanism, and an intelligent sensing system would be combined to form a retraction and deployment device with adaptive adjustment capabilities.

[0044] like Figures 1 to 6 The infrared GPS-based adaptive traffic cone deployment and retraction device shown includes a mounting frame 1 for mounting to the cargo box of a truck, and further includes:

[0045] The transverse platform 2 slides laterally on the mounting frame 1 via a displacement mechanism;

[0046] The upper end of the first guide frame 3 is hinged to the top of the transverse platform 2;

[0047] The second guide frame 4 is fixedly connected to the lower end of the first guide frame 3;

[0048] Each of the transverse platform 2, the first guide frame 3, and the second guide frame 4 is equipped with a separate conveyor belt system;

[0049] Guide plates 5 are symmetrically arranged on the surfaces of the first guide frame 3 and the second guide frame 4;

[0050] Two brackets 6 are symmetrically rotated and installed on the top of the second guide frame 4. An angle adjustment mechanism is provided between the brackets 6 and the second guide frame 4. A folding plate 7 is provided on the brackets 6. A gantry frame 8 is fixedly installed on the top of the two brackets 6.

[0051] The GPS positioning assistance system is used to calculate the position of the traffic cones in real time and ensure that the spacing between them is consistent.

[0052] The pushing mechanism, located on the side wall of the gantry frame 8, is used to assist in tilting the traffic cone;

[0053] The infrared sensing system is used during the road pile recovery phase to detect the road pile and control the operation of the propulsion mechanism to push the upper part of the road cone.

[0054] During implementation, the mounting frame 1 is fixed to the truck cargo box as a load-bearing foundation. The lateral moving platform 2 adjusts the placement position laterally using a displacement mechanism based on GPS positioning data to achieve an arc-shaped placement. The conveyor belt system operates synchronously in three sections, transporting the traffic cones from the storage area to the guide frame area. The first guide frame 3 adapts to vehicle bumps through a hinged structure, and the fixed connection of the second guide frame 4 forms a stable conveying channel. Symmetrically arranged guide plates 5 restrict the movement trajectory of the traffic cones to prevent deviation during transport. The guide plates 5 are L-shaped and limit the bottom of the traffic cones during use, ensuring stable transport of the traffic cones along the conveyor belt system. The traffic cones conveyed by the conveyor belt system on the second guide frame 4 fall onto the road surface. As the truck continues to move forward, two gathering plates 7 pass by the sides of the traffic cones, adjusting and correcting their position. When it is time to collect the traffic cones, the truck reverses, and the two gathering plates 7 gather the cones to be collected. Infrared sensor 21 detects upright traffic cones and triggers a pushing mechanism to block them. As the truck continues to reverse, the extended pushing mechanism tilts the traffic cone pile, allowing the conveyor belt system on the second guide frame 4 to reverse and complete the collection. The gantry frame 8 serves as a support frame for the pushing mechanism. The angle adjustment mechanism changes the spacing of the gathering plates 7 by adjusting the angle of the bracket 6, adapting to the collection and placement needs of traffic cones of different sizes.

[0055] GPS positioning assistance system: The GPS receiver calculates the position of the traffic cones in real time to ensure consistent spacing and neat arrangement, thus improving the accuracy of deployment and retrieval.

[0056] It should be noted that the conveyor belt conveying systems on the transverse platform 2, the first guide frame 3, and the second guide frame 4 are all composed of the same components and have the same working principle. The conveyor belt conveying system on the transverse platform 2 will be used as an example for explanation: The conveyor belt conveying system includes two rotating shafts, which are rotatably mounted on the transverse platform 2. The surfaces of the two rotating shafts are connected to the conveyor belt through conveyor rollers. A first sprocket is fixedly mounted on the surface of one of the rotating shafts. A DC differential motor is mounted on the side wall of the transverse platform 2. A second sprocket is fixedly mounted on the output shaft of the DC differential motor. A chain (not shown in the figure) is connected to the surfaces of the first sprocket and the second sprocket through transmission.

[0057] During implementation, when the DC differential motor starts, it drives the second sprocket to rotate. Under the transmission of the chain, the second sprocket will synchronously drive the first sprocket to rotate, thereby rotating the shaft connected to it, and thus realizing the rotation of the transmission belt to transport the road pile.

[0058] As one embodiment of this utility model, the displacement mechanism includes:

[0059] Rack 9 is fixedly installed on the top of mounting frame 1;

[0060] The drive motor 10 is fixedly mounted on the side wall of the transverse platform 2 by a fixed base. The output shaft end of the drive motor 10 passes through the fixed base and extends downwards, and a gear 11 is fixedly mounted thereon. The gear 11 meshes with the rack 9.

[0061] A guide component is positioned between the transverse platform 2 and the mounting frame 1.

[0062] During implementation, after the drive motor 10 starts, it drives the gear 11 to roll along the rack 9, converting the rotational motion into linear displacement of the transverse platform 2 through tooth meshing. The full tooth width contact between the gear 11 and the rack 9 ensures uniform force transmission and avoids transmission failure caused by localized stress concentration. The slide rail 12 and the sliding seat 13 in the guide assembly form a sliding pair, providing bidirectional constraint when the transverse platform 2 moves, offsetting the influence of lateral loads on transmission accuracy. The meshing clearance of the gear 11 and rack 9 is compensated by adjusting the mounting position of the fixed seat, ensuring that the backlash of the transmission system is controlled within 0.1 mm.

[0063] As one embodiment of this utility model, the guide assembly includes two slide rails 12, which are symmetrically and fixedly installed on the top of the mounting frame 1. Each slide rail 12 is slidably provided with a sliding seat 13, and all the sliding seats 13 are fixedly connected to the bottom of the transverse platform 2.

[0064] During implementation, the symmetrical installation of the two slide rails 12 forms a stable lateral movement reference plane, and the cooperation between the sliding seat 13 and the slide rail 12 constrains the movement path to a single degree of freedom. When the lateral platform 2 is driven by an external force, the sliding seats 13 on both slide rails 12 slide synchronously along the track axis. The contact surface between the sliding seat 13 and the slide rail 12 evenly distributes the load, avoiding jamming caused by local stress concentration. The rigid connection between the bottom of the platform and all the sliding seats 13 forms multi-point constraints, eliminating platform sway caused by assembly gaps. Especially in the vibration environment generated during vehicle operation, this structure can effectively absorb lateral impact energy.

[0065] In one embodiment of this utility model, a limiting plate 14 is fixedly installed on the side wall of the first guide frame 3, and the side wall of the limiting plate 14 is fixedly connected to the side wall of the transverse platform 2.

[0066] In implementation, the first guide frame 3 is fixedly connected to the transverse platform 2 via the limiting plate 14. During the movement of the transverse platform 2, this facilitates the synchronous movement of the first guide frame 3. Compared to existing technologies, traditional guide frames and transverse platforms 2 often use hinged or elastic connections, which are prone to accumulated gap errors under vibration or stress, causing the first guide frame 3 to shift. This solution, however, eliminates these gaps through the rigid connection between the limiting plate 14 and the transverse platform 2, directly transferring loads and enhancing the overall structural integrity.

[0067] As one embodiment of this utility model, the angle adjustment mechanism includes:

[0068] The clearance opening 601 is formed through the surface of the bracket 6;

[0069] The screw 15 is fixedly connected to the top of the second guide frame 4. The upper end of the screw 15 passes through the relief opening 601. Two nuts are threaded onto the surface of the screw 15. Adjusting the position of the two nuts on the screw 15 limits the angle of the second guide frame 4.

[0070] During implementation, the rotation of the bracket 6 causes the clearance port 601 to shift along the axis of the screw 15. By manually adjusting the relative positions of the two nuts on the screw 15, the upper and lower nuts abut against the upper and lower surfaces of the bracket 6, respectively, thus mechanically locking the rotation angle of the bracket 6. When the angle needs to be changed, simply loosen the nuts, rotate the bracket 6 to the target angle, and then tighten them again. The friction generated by the contact between the nuts and the surface of the bracket 6 prevents the bracket 6 from rotating accidentally. This solves the problem of fixing and adjusting the angle between the bracket 6 and the second guide frame 4, allowing the traffic cone deployment and retrieval device to quickly adjust the tilt angle of the guide frame according to the actual road slope, curve curvature, and other scenario requirements. This ensures that the traffic cone is stable in contact with the ground when placed and accurately aligned with the conveyor belt during retrieval, effectively improving the device's adaptability to different operating environments.

[0071] As one embodiment of this utility model, the driving mechanism includes:

[0072] Two vertically moving components are symmetrically arranged on the side wall of the gantry frame 8;

[0073] Two fixed covers 16 are fixedly installed on two vertical moving components respectively. Limiting ports 1601 are opened on the side walls of the two fixed covers 16. Electric push rods 17 are fixedly installed inside the two fixed covers 16. The piston rod end of each electric push rod 17 is rotatably connected to a lever 18. One end of each lever 18 passes through the corresponding limiting port 1601.

[0074] During implementation, the height adjustment function of the vertical moving component allows the pushing mechanism to be adjusted to the optimal force application position according to the specifications of the traffic cone. During the traffic cone retrieval process, when the infrared sensing system detects the traffic cone, it activates the electric push rod 17. The piston rod of the electric push rod 17 pushes the lever 18 to extend linearly along the trajectory defined by the limiting port 1601. The rotating connecting structure causes the lever 18 to generate angle compensation the instant it contacts the traffic cone, avoiding rigid collisions. The extended lever 18 blocks the top of the side wall of the traffic cone. As the truck drives the pushing mechanism to continue retracting, the extended lever 18 will push the top of the blocked traffic cone, causing the traffic cone to tilt. This facilitates the tilted traffic cone smoothly entering the conveyor belt system on the second guide frame 4, thus achieving traffic cone retrieval.

[0075] As one embodiment of this utility model, the vertical moving component includes a sliding sleeve 19. The vertical sliding sleeve 19 is disposed on the side wall of the gantry frame 8. A threaded hole is provided through the side wall of the sliding sleeve 19, and a threaded knob 20 is threaded inside the threaded hole. By turning the threaded knob 20, the sliding sleeve 19 is positioned by resisting the side wall of the gantry frame 8.

[0076] During implementation, after the sliding sleeve 19 moves up and down along the side wall of the gantry frame 8 to the target position, the threaded knob 20 is screwed into the threaded hole until its end is in close contact with the side wall of the gantry frame 8. The friction between the threaded knob 20 and the gantry frame 8 prevents the sliding sleeve 19 from shifting during vehicle movement or cone pushing. The position adjustment range of the sliding sleeve 19 covers the tilting force point height of cones of different sizes. During retrieval operations, the operator adjusts the position of the sliding sleeve 19 according to the actual height of the cone, aligning the lever 18 with the upper area of ​​the cone to ensure that the pushing action is precisely applied above the center of gravity of the cone. The self-locking characteristic of the threaded knob 20 prevents the sliding sleeve 19 from accidentally sliding down or shifting due to vehicle bumps.

[0077] As one embodiment of this utility model, the infrared sensing system includes two mounting bases, which are symmetrically mounted on the side wall of the gantry frame 8, and each mounting base is equipped with an infrared sensor 21.

[0078] In implementation, two mounting bases are fixed to the left and right sides of the gantry frame 8, forming a symmetrical spatial layout. Each mounting base has an infrared sensor 21 installed at a downward-sloping detection angle covering the cone's tipping path. When the cone enters the recycling area, the infrared signal reflected by its reflective surface material is captured by the sensor. The two sets of infrared sensors 21 are connected to the control system via parallel logic circuits. If either infrared sensor 21 detects a valid signal, it triggers the push mechanism, forming a dual-channel redundant detection mechanism.

[0079] Compared to existing technologies, traditional traffic cone recovery devices often use single-position sensors or mechanical triggering devices, which have blind spots that lead to missed detections. For example, when using a bottom contact switch, the traffic cone must be fully in a specific position to trigger, which cannot handle tilted or offset states. This solution uses symmetrically arranged infrared sensors 21 to construct a three-dimensional detection area, covering multiple spatial dimensions during the traffic cone tilting process, and can complete the detection action without physical contact.

[0080] Through the above technical solution, this application can sense the spatial position of the tipped traffic cone in real time and accurately control the start and stop timing of the pushing mechanism. The redundant design of the two sets of sensors eliminates the risk of single-point failure, ensuring reliable triggering of the actuator even under complex working conditions, and solving the problem of motion lag caused by blind spots during manual operation. The modular design of the mounting base facilitates adjustment of the detection angle according to the size of the traffic cone, adapting to the recycling needs of traffic cones of different specifications.

[0081] As one embodiment of this utility model, a warning light 22 is installed on the upper side wall of the gantry frame 8.

[0082] In implementation, the warning light 22 refers to a light source device capable of emitting visible light signals. Specifically, it can be implemented using an LED strobe light or a rotating warning light 22, utilizing high-brightness light-emitting units in conjunction with different flashing modes to enhance the visual warning effect. After the warning light 22 is installed above the side wall of the gantry frame 8, its light signal can diffuse horizontally in all directions. During the deployment and retraction of the traffic cones, when the device moves to the road construction area, the warning light 22 creates a dynamic warning effect through high-frequency flashing or rotating beams. Especially in environments with low visibility, the high-mounted warning light 22 can penetrate rain, fog, or dust, avoiding limited light coverage due to the device itself obstructing the path.

[0083] Compared to existing technologies, traditional traffic cone deployment and retraction devices typically lack independent warning devices or only employ static reflective markings at low locations, with their visibility limited by installation height and light reflection conditions. This solution overcomes the limitations of traditional passive reflective markings by integrating an active light source into the top structure of the device, achieving all-weather dynamic warning functionality while avoiding additional space occupation. This application effectively improves the warning visibility of traffic cone deployment and retraction devices in complex environments, especially at night or in adverse weather conditions, ensuring that passing vehicles and pedestrians can identify the work area in advance, proactively adjust their driving paths, and reduce the risk of collisions caused by obstructed vision.

[0084] As one embodiment of this utility model, auxiliary wheels 23 are provided on both sides of the second guide frame 4; the auxiliary wheels 23 are set to roll in contact with the ground, and the rolling of the auxiliary wheels 23 helps to support the second guide frame 4 during the raising and lowering of the traffic cone.

[0085] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
