Description

Technical Field

[0001] This invention relates to the field of traffic cone placement technology, specifically to a vehicle-mounted device for placing and retracting road traffic cones. Background Technology

[0002] With the continuous expansion of road traffic networks and the sustained growth of traffic volume, scenarios such as road maintenance, accident handling, and temporary traffic control place higher demands on the efficiency of traffic cone placement and retrieval. Under traditional operating methods, the placement and retrieval of traffic cones mainly rely on manual operation, requiring multiple workers to walk along the road. This results in significant problems such as slow operation speed, inconsistent placement spacing, and low safety. Especially in high-traffic sections or highway scenarios, manual operation not only causes traffic congestion but also exposes workers to high-risk environments, easily leading to secondary accidents.

[0003] Current automated placement of traffic cones still requires manual assistance. Personnel must place each cone individually onto a rotating cone holder, which then places them on the ground and rights them. However, this method is labor-intensive for large-scale deployments, resulting in high labor costs and cone damage rates. While existing automated equipment (such as cone handling vehicles) attempts to use robotic arms or conveyor belts for transport, their functionality is limited, still requiring manual positioning and calibration, and failing to achieve automatic grasping, precise placement, and orderly retrieval of cones. Therefore, developing a fully automated, efficient, and safe traffic cone handling device is an urgent need to improve road operation efficiency and personnel safety. To this end, an in-vehicle traffic cone handling device is proposed. Summary of the Invention

A rear placement rack is installed outside the transport vehicle's cargo compartment, and a transfer conveyor belt is installed on the rear placement rack. The horizontal conveyor belt is used to transport the traffic cones to the vertical conveyor belt, and the vertical conveyor belt is used to transfer the traffic cones to the transfer conveyor belt. A transfer structure is installed on the rear placement rack, and a placement structure is installed on one side of the transfer structure. The transfer structure is used to transfer the traffic cones to the placement structure. The transfer structure includes a support base, which is fixedly connected to the rear placement frame. A vertical support is rotatably connected to the support base. A lead screw is rotatably connected to the outside of the vertical support. A steering motor is fixedly connected inside the support base. The output shaft of the steering motor passes through the outer wall of the support base and is fixedly connected to the bottom of the vertical support. A movable connecting arm is threaded onto the outside of the lead screw. A snap-fit ​​structure is installed at the end of the movable connecting arm away from the lead screw. A drive motor is fixedly connected to the top of the vertical support. The output shaft of the steering motor passes through the outer wall of the vertical support and is fixedly connected to one end of the lead screw.

[0006] Preferably, the snap-fit ​​structure includes an open socket barrel, which is fixedly connected to the end of the movable connecting arm away from the lead screw. A plurality of hydraulic cylinders are fixedly connected to the bottom of the open socket barrel, and an inclined lifting plate is fixedly connected to the telescopic end of the hydraulic cylinder. The open socket barrel is used to fit the traffic cone and lift the bottom of the traffic cone by pushing the inclined lifting plate through the hydraulic cylinder.

[0007] Preferably, the placement structure includes a guide frame, which is fixedly connected to the outside of the rear placement frame. The top and bottom of the guide frame are open. A transverse support plate is fixedly connected inside the guide frame, and two limiting plates are fixedly connected to the transverse support plate.

[0008] Preferably, the placement structure further includes a connecting support plate, which is fixedly connected to the side of the transverse support plate away from the rear placement frame. A rotating arm is rotatably connected to the outside of the connecting support plate via a rotating shaft. A rotary guide motor is rotatably connected to the side of the connecting support plate away from the rotating arm. The output shaft of the rotary guide motor is fixedly connected to the rotating shaft of the rotating arm. A first rotating seat is rotatably connected to the outside of the rotating arm via a rotating shaft. A connecting rod is fixedly connected to the outside of the first rotating seat. A second rotating seat is rotatably connected to the side of the connecting support plate away from the rotary guide motor via a rotating shaft. An insertion hole is provided on the outside of the second rotating seat. A fixed plate is slidably connected inside the insertion hole. A fixed plate is fixedly connected to the end of the connecting rod away from the first rotating seat. Two clips are fixedly connected to the outside of the fixed plate.

[0009] Preferably, the front end of the clamp is made of elastic rubber, one of the two clamps is used to engage the top periphery of the traffic cone, and the other clamp is used to engage the bottom periphery of the traffic cone, and two electromagnets are installed inside each clamp.

[0010] Preferably, the side of the inclined lifting plate closest to the traffic cone is made of rubber, and the front part of the rubber inclined lifting plate is used to squeeze and clamp the traffic cone when the hydraulic cylinder drives the inclined lifting plate to fit against the outside of the traffic cone.

[0012] Preferably, the guide frame is externally fixedly connected to a lateral connecting rod, and a push rod is fixedly connected between the two lateral connecting rods.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the horizontal and vertical conveyor belts in the transport container work together to achieve continuous transport of traffic cones without the need for repeated manual handling and stacking. The transfer conveyor belt on the rear placement rack further transports the traffic cones to the designated location, forming a continuous operation process from stacking to transporting and then to transfer. Compared with manual bending over to carry and placing them one by one, this significantly shortens the overall time for deployment and retrieval, and can quickly respond to the deployment needs of large-scale road operations.

In the placement structure, the rotary guide motor drives the rotating arm, connecting rod, and fixing plate to move. The transfer and placement of traffic cones are completed by clamps. The entire process does not require operators to bend over or carry the cones, completely freeing up manpower. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-7 As shown, this application discloses a road traffic cone in-vehicle storage and retrieval device, including a transport vehicle 100. The upper part of the transport vehicle 100 is connected to a transport carrying compartment 101. The transport carrying compartment 101 is equipped with a horizontal conveyor belt 103 and a vertical conveyor belt 102. A rear placement rack 104 is installed on the outside of the transport vehicle 100. A transfer conveyor belt 105 is installed on the rear placement rack 104. The horizontal conveyor belt 103 is used to transport traffic cones to the vertical conveyor belt 102, and the vertical conveyor belt 102 is used to transfer traffic cones to the transfer conveyor belt 105. A transfer structure is installed on the rear placement rack 104, and a placement structure is installed on one side of the transfer structure. The transfer structure is used to transfer traffic cones to the placement structure. The transfer structure includes a support 200, which is fixedly connected to the rear placement frame 104. A vertical support 202 is rotatably connected to the support 200. A lead screw 203 is rotatably connected to the outside of the vertical support 202. A steering motor 201 is fixedly connected inside the support 200. The output shaft of the steering motor 201 passes through the outer wall of the support 200 and is fixedly connected to the bottom of the vertical support 202. A movable connecting arm 206 is threadedly connected to the outside of the lead screw 203. A snap-fit ​​structure is installed at the end of the movable connecting arm 206 away from the lead screw 203. A drive motor 204 is fixedly connected to the top of the vertical support 202. The output shaft of the steering motor 201 passes through the outer wall of the vertical support 202 and is fixedly connected to one end of the lead screw 203.

[0019] Specifically, during use, staff can stack a large number of traffic cones onto the horizontal conveyor belt 103. After the traffic cones are placed, the transport vehicle 100 is started to place the traffic cones on the designated road. While placing the traffic cones, the vertical conveyor belt 102 is started to continuously transport the traffic cones on the vertical conveyor belt 102 to the outside of the transfer conveyor belt 105. After the traffic cones on the vertical conveyor belt 102 are completely transported to the outside of the transfer conveyor belt 105, the horizontal conveyor belt 103 can be started to continuously transport the traffic cones back to the vertical conveyor belt 102, forming a continuous traffic cone transport. After the traffic cones are transported to the transfer conveyor belt 105, the transfer conveyor belt 105 will transport the traffic cones to the designated position. After the traffic cones are transported to the designated position, the transfer structure is started to place the traffic cones one by one onto the placement structure, and the traffic cones are placed on the ground on the placement structure.

[0020] Furthermore, in the transfer structure, starting the steering motor 201 can drive the vertical support 202 to rotate as a whole. When the vertical support 202 rotates as a whole, it can drive the movable connecting arm 206 and the open socket 207 to rotate. After the traffic cone is placed on the transfer conveyor belt 105, starting the steering motor 201 drives the vertical support 202 to rotate towards the direction of the transfer conveyor belt 105, and starting the drive motor 204 drives the lead screw 203 to rotate. When the lead screw 203 rotates, it will drive the movable connecting arm 206 and the open socket 207 to move above the traffic cone on the transfer conveyor belt 105. As the lead screw 203 rotates, it will drive the open socket 207 to descend and fit the traffic cone. After the fitting is completed, the traffic cone is lifted by the snap-fit ​​structure, and the traffic cone is transferred to the placement structure by continuously starting the steering motor 201.

[0021] like Figure 5 As shown, the snap-fit ​​structure includes an open socket barrel 207, which is fixedly connected to the end of the movable connecting arm 206 away from the lead screw 203. Multiple hydraulic cylinders 208 are fixedly connected to the bottom of the open socket barrel 207. An inclined lifting plate 205 is fixedly connected to the telescopic end of the hydraulic cylinder 208. The open socket barrel 207 is used to fit the traffic cone and push the inclined lifting plate 205 to lift the bottom of the traffic cone through the hydraulic cylinder 208.

[0022] Specifically, during use, after the movable connecting arm 206 drives the open socket 207 to be fitted onto the outside of the traffic cone, multiple hydraulic cylinders 208 can be activated to drive the inclined lifting plate 205 to extend forward. When the inclined lifting plate 205 extends forward, and multiple traffic cones are stacked together, the front end of the inclined lifting plate 205 can be inserted into the gap between the multiple traffic cones. After the inclined lifting plate 205 is inserted into the gap at the front end of the traffic cone, it forms a snap-fit ​​on the traffic cone. By reversing the start of the drive motor 204, the lead screw 203 can be driven to rotate in the opposite direction, thereby driving the movable connecting arm 206, the open socket 207, and the traffic cone snapped by multiple inclined lifting plates 205 to be lifted upward, thus lifting a single traffic cone. After being lifted, the rotation of the steering motor 201 drives the vertical support 202, the movable connecting arm 206, the open socket 207, and the traffic cone snapped by multiple inclined lifting plates 205 to rotate together to the top of the placement structure.

[0023] like Figures 1-7 As shown, the placement structure includes a guide frame 403, which is fixedly connected to the outside of the rear placement frame 104. The top and bottom of the guide frame 403 are open. A transverse support plate 400 is fixedly connected inside the guide frame 403, and two limiting plates 401 are fixedly connected to the transverse support plate 400. The placement structure also includes a connecting support plate 300, which is fixedly connected to the side of the transverse support plate 400 away from the rear placement frame 104. A rotating arm 302 is rotatably connected to the outside of the connecting support plate 300 via a rotating shaft. A rotary guide motor 3 is rotatably connected to the side of the connecting support plate 300 away from the rotating arm 302. 01. The output shaft of the rotary guide motor 301 is fixedly connected to the rotating shaft of the rotary arm 302. The outside of the rotary arm 302 is rotatably connected to the first rotating seat 303 via the rotating shaft. The outside of the first rotating seat 303 is fixedly connected to the connecting bearing plate 300 away from the rotary guide motor 301 via the rotating shaft to the second rotating seat 304. The outside of the second rotating seat 304 is provided with an insertion hole. The fixing plate 306 is slidably connected inside the insertion hole. The end of the connecting rod 305 away from the first rotating seat 303 is fixedly connected to the fixing plate 306. The outside of the fixing plate 306 is fixedly connected to two clips 307.

[0024] Specifically, during use, after the open-end socket 207 rotates to the top of the placement structure, the operator can restart the drive motor 204 to rotate the lead screw 203. The rotation of the lead screw 203 causes the moving connecting arm 206 and the open-end socket 207 to descend, thereby placing the traffic cone inside the open-end socket 207 onto the transverse support plate 400. The two limiting plates 401 limit the traffic cone's position on both sides, preventing it from deviating too much. The open-end socket 207 is then moved to the two limiting plates... After 401, the hydraulic cylinder 208 is reversed to separate the inclined lifting plate 205 from the traffic cone. After separation, the traffic cone will fall above the transverse support plate 400. At this time, the rotary guide motor 301 is started to drive the rotating arm 302 to rotate. The rotation of the rotating arm 302 will cause the first rotating seat 303 to circle around the rotating arm 302. While circling, the first rotating seat 303 will change direction with the rotation of the rotating arm 302 and drive the connecting rod 305 to slide inside the second rotating seat 304, thereby driving the fixed... As plate 306 changes direction, the rotation and rotation of the guide motor 301 cause the fixed plate 306 and clamps 307 to move towards the traffic cone above the transverse support plate 400 and towards the road surface, respectively. When the fixed plate 306 moves the two clamps 307 towards the two limiting plates 401, the two clamps 307 first push the traffic cone located between the two limiting plates 401. After the traffic cone is pushed against the inner wall of the placement frame 104 and cannot move, the elastic clamps 307 deform and lock the traffic cone in place. After the traffic cone is engaged, the rotary guide motor 301 is started in the opposite direction to move the fixing plate 306 and the clamp 307 toward the ground. When the fixing plate 306 and the clamp 307 are moved to the ground position, the two electromagnets 308 located outside the clamp 307 are activated, so that the two electromagnets 308 generate opposite repulsive forces. Under the condition of generating opposite repulsive forces, the clamping plates on both sides of the clamp 307 can be opened, so that the clamp 307 loses its engaging state with the traffic cone, thereby separating the traffic cone from the two clamps 307.

[0025] like Figure 3 As shown, the front end of the clip 307 is made of elastic rubber. One of the two clips 307 is used to engage the top periphery of the traffic cone, and the other clip 307 is used to engage the bottom periphery of the traffic cone. Each clip 307 has two electromagnets 308 installed inside.

[0026] Specifically, the elastic rubber clip 307 can work with the two electromagnets 308 installed inside the clip 307 to form opposite thrust deformations. Under the condition of opposite thrust deformations, the traffic cone can be separated from the elastic section at the front of the clip 307, thereby separating the traffic cone from the clip 307.

[0027] like Figure 5 As shown, the side of the inclined lifting plate 205 closest to the traffic cone is made of rubber. The front end of the rubber inclined lifting plate 205 is used to squeeze and clamp the traffic cone when the hydraulic cylinder 208 drives the inclined lifting plate 205 to fit against the outside of the traffic cone.

[0028] Specifically, during use, when the stacked traffic cones are transferred to a point where only one remains after the cooperation of the open-end socket 207, hydraulic cylinder 208, and inclined lifting plate 205, the bottom of the remaining traffic cone is in contact with the transfer conveyor belt 105. Because of this contact, the inclined portion at the front end of the inclined lifting plate 205 cannot extend between the last traffic cone and the transfer conveyor belt 105, resulting in the inability to lift the last traffic cone. Therefore, the front end of the inclined lifting plate 205 is made of rubber. When only one traffic cone remains, the hydraulic cylinder 208 drives the front end of the inclined lifting plate 205 to directly press against the outer wall of the traffic cone. This causes multiple inclined lifting plates 205 to directly press and limit the outer wall of the traffic cone. With this pressing and limiting effect, the entire traffic cone can be clamped and then transferred again, completing the transfer of the last traffic cone on the transfer conveyor belt 105.

[0029] like Figures 2-7 As shown, a bearing rod 402 is fixedly connected to one side of each of the two limiting plates 401.

[0030] Specifically, during use, when the traffic cones are transferred and moved from the ground to the transverse support plate 400 using the fixing plate 306, they are placed on multiple support rods 402. The support rods 402 act as transverse supports, with a certain height between them and the transverse support plate 400. This ensures that when the traffic cones are placed on the support rods 402, there is a certain distance between them and the transverse support plate 400, meaning they are suspended in mid-air. At this point, when the open-ended connecting bucket 207 is used in conjunction with the hydraulic cylinder 208 and the inclined lifting plate 205 to move the traffic cones above them for retrieval, the hydraulic cylinder 208 and the inclined lifting plate 205 can be moved to the gap below the multiple support rods 402 and the traffic cones. This provides space for the inclined lifting plate 205 to extend under the traffic cones, making it convenient to transfer the traffic cones one by one back to the transfer conveyor belt 105 for retrieval when collecting them.

[0031] like Figures 1-2As shown, a lateral connecting rod 500 is fixedly connected to the outside of the guide frame 403, and a push rod 501 is fixedly connected between the two lateral connecting rods 500.

[0032] Specifically, during use, after the fixing plate 306 and clamp 307 move the traffic cone located on the transfer conveyor belt 105 to the ground, the traffic cone moved to the ground is in a tilted state, such as... Figure 1 As shown, after the traffic cone tilts, the transport vehicle 100 continues to move, driving the guide frame 403 and the push rod 501 to move continuously. This allows the push rod 501 to move to the outside of the tilted traffic cone, thus moving the outside of the push rod 501. As the transport vehicle 100 moves forward, it can work with the push rod 501 to move the traffic cone back to its original position, making the traffic cone vertical. When recycling, the transport vehicle 100 reverses. When reversing, the push rod 501 will push the vertical traffic cone over. After the traffic cone is pushed over, the fixing plate 306 and the clamp 307 can be used to pick up the overturned traffic cone and place it on the support rod 402. After being placed on the support rod 402, the traffic cone is transferred to the transfer conveyor belt 105 for recycling using the transfer structure.

[0033] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the horizontal conveyor belt 103 and the vertical conveyor belt 102 in the transport carrying compartment 101 can be used to realize the continuous transport of traffic cones without the need for manual repeated handling and stacking. The transfer conveyor belt 105 on the rear placement rack 104 further transports the traffic cones to the designated position, forming a continuous operation process from stacking to transporting and then to transfer. Compared with manual bending over to carry and placing them one by one, the overall time for deployment and recovery is greatly shortened, and the deployment needs of large-scale road operations can be responded to quickly. In this embodiment, the fully automated grabbing, transporting, and placing of traffic cones is achieved through a transfer structure and a placement structure. In the transfer structure, the steering motor 201 on the bearing seat 200 drives the vertical support 202 to rotate, and the drive motor 204 drives the lead screw 203 to rotate, thereby driving the moving connecting arm 206 and the open sleeve bucket 207 to move. With the help of the hydraulic cylinder 208 and the tilting lifting plate 205, the traffic cones are automatically clamped and lifted. In the placement structure, the rotary guide motor 301 drives the rotating arm 302, the connecting rod 305, and the fixing plate 306 to move. The transfer and placement of traffic cones are completed through the clamp 307. The entire process does not require operators to bend over or carry the cones, completely freeing up manpower.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
