Description

Technical Field

[0001] This application belongs to the field of automatic traffic cone placement technology, and specifically relates to an automatic traffic cone placement device. Background Technology

[0002] With the vigorous development of infrastructure construction, it is often necessary to place traffic cones during road construction. In existing technology, engineering vehicles are often equipped with traffic cone placement devices. These devices typically use a robotic arm composed of 3-5 rotating joints to clamp the vertically placed traffic cone with its cone facing upwards. The cone is then placed on the ground vertically with its cone facing upwards through the coordinated rotation of each joint. In actual implementation, the robotic arm has many rotating joints, a complex structure, and requires precise coordination of each joint. This results in high precision requirements, high implementation costs, and poor clamping stability because the cone is held with its cone facing upwards and its center pointing downwards. Improvements are urgently needed. Summary of the Invention

[0037] like Figure 1-14 As shown, to further illustrate this technical solution, the automatic traffic cone placement device includes an engineering vehicle A1, a placement mechanism A2 mounted on the engineering vehicle A1, and a conveying assembly C1 located inside the engineering vehicle A1. The conveying assembly C1 is used to convey a traffic cone X with its cone facing downwards to the placement mechanism A2. The placement mechanism A2 includes a base A20 mounted on the engineering vehicle A1, a connecting rod A21 rotatably mounted on the base A20, and a clamping assembly A22 mounted on the connecting rod A21 near one end of the conveying assembly C1. The clamping assembly A22 is used to clamp the traffic cone X, which is placed vertically with its cone facing downwards. The connecting rod A21 can be flipped away from the base A20 to place the traffic cone X vertically with its cone facing upwards onto the ground.

[0038] This application provides an automatic traffic cone placement device, including an engineering vehicle, a placement mechanism, a traffic cone compartment, and a conveying assembly. The placement mechanism includes a base, a connecting rod, and a clamping assembly. The clamping assembly clamps the traffic cones in the traffic cone compartment vertically with the cones facing downwards, and flips them away from the base via the connecting rod, so that the traffic cones are placed on the road surface vertically with the cones facing upwards. During the clamping process, the center of gravity of the traffic cones is close to the clamping assembly, resulting in high clamping stability. The placement of the traffic cones is completed by a set of rotating joints on the connecting rod and the base, eliminating the need for multiple rotating joints for precise coordination. This device has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and ease of promotion and implementation.

[0039] Preferably, the clamping assembly A22 includes a drive assembly A220 disposed on the connecting rod A21, a first arc-shaped gripper A221 disposed on one side of the drive assembly A220, and a second arc-shaped gripper A222 disposed opposite to the first arc-shaped gripper A221 and located on the other side of the drive assembly A220. The drive assembly A220 is used to simultaneously drive the first arc-shaped gripper A221 and the second arc-shaped gripper A222 to move toward or away from each other to clamp the traffic cone X.

[0040] In actual implementation, the first and second arc-shaped grippers are driven by the drive component to move towards or away from each other, which can meet the clamping requirements of different specifications of traffic cones and further improve clamping stability. During the flipping process, the traffic cone falls, and the clamping component clamps the traffic cone vertically with the cone facing downward. Then, it is flipped away from the base by the connecting rod, so that the traffic cone is placed on the road surface vertically with the cone facing upward. During the clamping process, the center of gravity of the traffic cone is close to the clamping component, and the clamping stability is high. The placement of the traffic cone is completed by a set of rotating joints of the connecting rod and the base. There is no need for multiple rotating joints to make precise coordination. It has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and easy promotion and implementation.

[0041] Preferably, the drive assembly A220 includes a first drive member A223 disposed on the connecting rod A21, a rack A224 disposed on the connecting rod A21, a first gear disk A225 disposed on one side of the rack A224 and meshing with the rack A224, and a second gear disk A226 disposed on the other side of the rack A224 and meshing with the rack A224. The first arc-shaped gripper A221 is disposed on the first gear disk A225, and the second arc-shaped gripper A222 is disposed on the second gear disk A226. The first drive member A223 can drive the rack A224 to move along its length direction and drive the first gear disk A225 and the second gear disk A226 to rotate, so that the first arc-shaped gripper A221 and the second arc-shaped gripper A222 move towards or away from each other.

[0042] In actual implementation, the rack and the first and second toothed discs drive the first and second arc-shaped grippers to rotate in opposite directions, which can linearly adjust the clamping particle size and improve clamping stability. The clamping assembly clamps the road cone vertically with the cone facing downwards, and flips it away from the base via the connecting rod, so that the road cone is placed on the road surface vertically with the cone facing upwards. During the clamping process, the center of gravity of the road cone is close to the clamping assembly, resulting in high clamping stability. The placement of the road cone is completed by a set of rotating joints of the connecting rod and the base, without the need for multiple rotating joints for precise coordination. It has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and easy promotion and implementation.

[0043] Preferably, the first arc-shaped gripper A221 and / or the second arc-shaped gripper A222 are provided with teeth Y on their inner sides. By providing teeth, the contact area between the first arc-shaped gripper / second arc-shaped gripper and the traffic cone is increased, thereby improving the clamping stability. The traffic cone is clamped vertically with the cone facing downwards by the clamping assembly, and then flipped away from the base by the connecting rod, so that the traffic cone is placed on the road surface vertically with the cone facing upwards. During the clamping process, the center of gravity of the traffic cone is close to the clamping assembly, resulting in high clamping stability. The placement of the traffic cone is completed by a set of rotating joints of the connecting rod and the base, without the need for multiple rotating joints for precise coordination. It has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and easy promotion and implementation.

[0044] Preferably, a flipping mechanism A3 is provided between the base A20 and the connecting rod A21 for driving the connecting rod A21 to flip in a direction away from or towards the conveying assembly C1. The flipping mechanism A3 includes a second driving member A30 disposed on the base A20 and a flipping wheel assembly A31 disposed on the output end of the second driving member A30. The second driving member A30 can drive the flipping wheel assembly A31 to rotate, thereby causing the connecting rod A21 to flip in a direction away from or towards the conveying assembly C1.

[0045] In actual implementation, the connecting rod is driven to flip relative to the base by the flipping mechanism. This flips the road cone, which is vertically oriented with its cone facing upward, onto the ground. The clamping assembly holds the road cone vertically with its cone facing downward, and then flips it away from the base by the connecting rod, placing the road cone vertically with its cone facing upward on the road surface. During the clamping process, the center of gravity of the road cone is close to the clamping assembly, resulting in high clamping stability. The placement of the road cone is completed by a set of rotating joints on the connecting rod and the base, without the need for multiple rotating joints for precise coordination. This method has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and easy promotion and implementation.

[0046] Preferably, the flipping wheel assembly A31 includes a drive gear disk A310 disposed on the output end of the second drive member A30, a driven gear disk A311 hinged to the base A20, and a chain A312 meshing between the drive gear disk A310 and the driven gear disk A311. The connecting rod A21 is hinged to the driven gear disk A311. The second drive member A30 can drive the drive gear disk A310 to rotate, and drive the chain A312 to rotate around the drive gear disk A310, thereby driving the driven gear disk A311 to rotate, and thus driving the connecting rod A21 to flip away from or towards the conveying assembly C1.

[0047] In actual implementation, the chain can be replaced with a belt. Through the cooperation of the active and driven toothed discs, the rotation angle of the connecting rod relative to the base can be linearly adjusted. The clamping assembly holds the traffic cone vertically with the cone facing downwards, and the connecting rod rotates it away from the base, so that the traffic cone is placed on the road surface vertically with the cone facing upwards. During the clamping process, the center of gravity of the traffic cone is close to the clamping assembly, resulting in high clamping stability. The placement of the traffic cone is completed by a set of rotating joints of the connecting rod and the base, without the need for multiple rotating joints for precise coordination. It has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and easy promotion and implementation.

[0048] Preferably, the drive gear A310 includes a first driven gear and a second driven gear spaced apart therefrom, and the chain A312 has two branches, which mesh with the first driven gear and the second driven gear respectively.

[0049] Preferably, the radius r of the driving toothed disk A310 and the radius R of the driven toothed disk A311 satisfy the following relationship: 0 < r ≤ R.

[0050] Preferably, the ground clearance h of the driving gear disk A310 and the ground clearance H of the driven gear disk A311 satisfy the following relationship: 0 < h < H.

[0051] Preferably, a buffer block A4 is provided between the connecting rod A21 and the base A20, and the connecting rod A21 can be flipped toward the base A20 to fit against the buffer block A4.

[0052] In actual implementation, by setting a rubber buffer block between the base and the connecting rod, damage to the connecting rod or base can be avoided during the flipping process.

[0053] In actual implementation, the traffic cone compartment A5 includes a frame B1, a receiving mechanism B2 disposed on the frame B1 for receiving traffic cones X, a cone dispensing mechanism B3 disposed on the frame B1 and located below the receiving mechanism B2, and a driving mechanism B4 disposed between the cone dispensing mechanism B3 and the frame B1. The traffic cones X are stacked sequentially from the inside to the outside in the receiving mechanism B2 along the horizontal direction. The driving mechanism B4 is used to drive the cone dispensing mechanism B3 to match and extend into the gap between two adjacent traffic cones X, and drive the traffic cones X to move out of the receiving mechanism B2.

[0054] Preferably, the cone ejection mechanism B3 includes connecting rods B30 disposed on both sides of the frame B1 and located below the receiving mechanism B2, and a ejector frame B31 connected between the two connecting rods B30. The driving mechanism B4 can drive the ejector frame B31 to extend into the gap between two adjacent cones X and drive the cone X to move outward from the receiving mechanism B2.

[0055] In actual implementation, the two ends of the connecting rod are connected to the drive mechanism, which is distributed on the four legs of the frame and the middle of the two connecting rods. The drive mechanism drives the ejector to extend into the gap between two adjacent cones in the receiving mechanism and pushes the cones out of the receiving mechanism. This means that the engineering vehicle is not affected by the stacking height of the cones during the transportation of cones, which increases the single transportation capacity of cones. There is no need to use a robotic arm to pull out the cones. Instead, the cones are pushed out of the receiving mechanism by extending into the gap between two adjacent cones. The structure is greatly simplified, the maintenance cost is significantly reduced, the operational stability is significantly improved, and the cones can be accurately ejected. It has the advantages of being easy to operate and easy to promote and implement.

[0056] Preferably, the drive mechanism B4 includes a vertical drive assembly B40 disposed between the frame B1 and the connecting rod B30, and a horizontal drive assembly B41 disposed between the connecting rod B30 and the ejector frame B31. The vertical drive assembly B40 is used to drive the connecting rod B30 to move along the height direction of the frame B1, and the horizontal drive assembly B41 is used to drive the ejector frame B31 to move along the length direction of the connecting rod B30.

[0057] Preferably, the vertical drive assembly B40 includes a vertical drive member B400 disposed on the frame B1, a vertical slide rail B401 disposed between the frame B1 and the connecting rod B30, and a vertical slider B402 slidably disposed on the vertical slide rail B401 and connected to the connecting rod B30. The vertical drive member B400 is used to drive the connecting rod B30 to move along the height direction of the vertical slide rail B401.

[0058] In actual implementation, the vertical drive component is located on each leg of the frame. The vertical drive component is either a drive cylinder or a drive motor. The vertical slider is bolted to both ends of each connecting rod. The output end of the vertical drive component is connected to the vertical slider. The vertical slide rail is located on each leg of the frame along the height direction of the frame. The vertical drive component drives the vertical slider to slide along the vertical slider, thereby driving the ejector frame to extend into the gap between two adjacent cones in the receiving mechanism and push the cones out of the receiving mechanism. This allows the engineering vehicle to transport cones without being affected by the stacking height of the cones, increasing the single transport capacity of cones. It also eliminates the need for a robotic arm to remove cones; instead, it pushes them out of the receiving mechanism by extending into the gap between two adjacent cones. The structure is greatly simplified, maintenance costs are significantly reduced, and operational stability is significantly improved. It can accurately eject cones and has the advantages of being easy to operate and easy to promote and implement.

[0059] Preferably, the horizontal drive assembly B41 includes a horizontal drive member B410 disposed on the connecting rod B30 and connected at its output end to the ejector frame B31, a horizontal slide rail B411 disposed between the ejector frame B31 and the connecting rod B30, and a horizontal slider B412 slidably disposed on the horizontal slide rail B411 and connected to the ejector frame B31. The horizontal drive member B410 is used to drive the ejector frame B31 to move along the length direction of the horizontal slide rail B411.

[0060] In actual implementation, the horizontal drive component is a drive cylinder or drive motor, located in the middle of the connecting rod. The horizontal slider is located on the ejector frame, and the output end of the horizontal drive component is connected to the horizontal slider. The horizontal slide rail is located inside the connecting rod and distributed at both ends of the connecting rod. The horizontal drive component can drive the ejector frame to move along the horizontal slide rail. The vertical drive component drives the vertical slider to slide along the vertical slider, thereby driving the ejector frame to extend into the gap between two adjacent cones in the receiving mechanism. The horizontal drive component then drives the ejector frame to move along the horizontal slide rail, pushing the cone out of the receiving mechanism. This allows the engineering vehicle to transport cones without being affected by the stacking height of the cones, increasing the single transport capacity of the cones. It also eliminates the need for a robotic arm to remove the cones; instead, the cones are pushed out of the receiving mechanism by extending into the gap between two adjacent cones. The structure is greatly simplified, maintenance costs are significantly reduced, and operational stability is significantly improved. It can accurately eject the cones and has the advantages of being easy to operate and easy to promote and implement.

[0061] Preferably, the ejector frame B31 includes a main frame B310 and ejector tubes B311 disposed on the main frame B310 and located at corresponding positions below each of the traffic cones X within the receiving mechanism B2. Multiple ejector tubes B311 are spaced apart along the length of the main frame B310. The vertical drive assembly B40 can drive the main frame B310 to move along the height direction of the frame B1, thereby causing the ejector tubes B311 to extend into the gap between two adjacent traffic cones X. The horizontal drive assembly B41 can drive the main frame B310 to move horizontally along the frame B1, thereby ejecting the traffic cone X from the receiving mechanism B2 through the ejector tubes B311.

[0062] In actual implementation, a ring is provided between two adjacent traffic cones. When the traffic cones are stacked in the horizontal direction, the ring is used to limit the distance between two adjacent traffic cones. The main frame is provided with an ejector tube that moves towards the receiving mechanism. Each ejector tube can be matched and extended into the gap between two adjacent traffic cones. Through the horizontal driving member, the ejector tube abuts against the bottom surface of the traffic cone, thereby ejecting the traffic cone out of the receiving mechanism.

[0063] Preferably, the accommodating mechanism B2 includes an accommodating channel B20 disposed on the frame B1, and a traffic cone sleeve B21 disposed in the accommodating channel B20. When the traffic cone X is inserted into the traffic cone sleeve B21, a plurality of traffic cones X can be stacked sequentially in the accommodating channel B20 along the length direction of the frame B1.

[0064] Preferably, a sliding component B22 is provided between the traffic cone sleeve B21 and the receiving channel B20. When the vertical drive component B40 drives the ejector frame B31 to move closer to the traffic cone sleeve B21 along the height direction of the frame B1, the traffic cone sleeve B21 can be matched and extended into the gap between two adjacent ejector tubes B311 located below the traffic cone sleeve B21. The horizontal drive component B41 can drive the ejector frame B31 to move along the horizontal direction of the frame B1, and drive the traffic cone sleeve B21 to move along the length direction of the sliding component B22 through the ejector tubes B311, so as to eject the traffic cone X from the receiving channel B20.

[0065] Preferably, the sliding component B22 includes an inner slide rail B220 disposed between the accommodating channel B20 and the traffic cone sleeve B21, and an inner slider B221 that is slidably disposed on the inner slide rail B220 and connected to the traffic cone sleeve B21, wherein the inner slide rail B220 is disposed along the length direction of the accommodating channel B20.

[0066] In actual implementation, the traffic cone sleeve is located at the innermost part of the receiving channel, with the cone facing the sleeve. The cones are stacked sequentially along the length of the receiving channel, and a ring is provided between two adjacent cones. The cone sleeve can be matched and extended into the gap between two adjacent ejector tubes at the corresponding position of the cone sleeve, so that each cone and each ejector tube are alternately set. When the horizontal drive unit drives the main frame to move, the ejector tube at the corresponding position of the cone sleeve is matched and set on one side of the cone sleeve. After the horizontal drive unit is started, it abuts against the cone sleeve, driving the cone sleeve to move along the length of the inner slide rail. Each ejector tube abuts against the bottom of the cone, driving the cone to move outward from the receiving mechanism.

[0067] Preferably, the accommodating mechanism B2 is provided with multiple units spaced apart along the width direction of the frame B1.

[0068] In actual implementation, multiple containment mechanisms are set up, which can eject multiple traffic cones each time, thus improving efficiency.

[0069] In actual implementation, the conveying component C1 is provided with a cone clamping mechanism C2 for clamping the traffic cone X. The conveying component C1 is used to convey the traffic cone X clamped by the cone clamping mechanism C2 to the placement mechanism A2. The cone clamping mechanism C2 includes a fixed seat C20 provided on the conveying component C1 and a clamping claw group C21 provided on the fixed seat C20. The traffic cone X can be clamped on the clamping claw group C21 in a vertical direction with the cone portion facing downward.

[0070] Preferably, the gripper assembly C21 includes an upper gripper C210 disposed on the fixed base C20, and a lower gripper C211 disposed on the fixed base C20 and located below the upper gripper C210. ​​The road cone X can be clamped vertically and downwardly on both the upper gripper C210 and the lower gripper C211.

[0071] In actual implementation, the cone is clamped vertically downwards onto the upper and lower grippers. The cone's cross-sectional radius gradually increases from the cone to the bottom. Placing the cone downwards raises its center of gravity, improving clamping stability. Furthermore, it facilitates the placement mechanism by flipping the cone with the cone facing downwards onto the road surface, placing it with the cone facing upwards on the bottom surface. After the cone is clamped vertically with the cone facing downwards by the gripper assembly, it is then conveyed to the corresponding position on the placement mechanism via the conveyor assembly. This avoids the situation where a single cone falling over on the conveyor belt can cause other cones to fall over as well, delaying subsequent cone placement. It also solves the problem of belt conveyors being greatly affected by the inertia of the conveyor drive components. It has the advantages of being easy to use, simple to operate, low in implementation cost, and easy to promote and implement.

[0072] Preferably, the upper gripper C210 includes a first gripper C212 rotatably mounted on the fixed base C20, a second gripper C213 rotatably mounted on the fixed base C20, and a reset assembly C22 disposed between the first gripper C212 and the second gripper C213. The first gripper C212 and the second gripper C213 can rotate towards or away from each other. The traffic cone X is clamped between the first gripper C212 and the second gripper C213. When the first gripper C212 and the second gripper C213 rotate away from each other, the reset assembly C22 can drive the first gripper C212 and the second gripper C213 to rotate towards each other.

[0073] Preferably, the reset assembly C22 includes a fixing hole C220 disposed between the first claw C212 and the second claw C213, and an elastic element C221 connected to the fixing hole C220 at both ends. When the first claw C212 and the second claw C213 rotate in opposite directions, the elastic element C221 can be stretched to generate elastic deformation, thereby driving the first claw C212 and the second claw C213 to rotate in opposite directions so that they are reset.

[0074] In actual implementation, a clamping channel is formed between the first and second claw plates to match and clamp the traffic cone. When the cross-sectional radius of the traffic cone is greater than the radius of the clamping channel, the traffic cone will drive the first and second claw plates to rotate in opposite directions, and the radius of the clamping channel will increase. At this time, the reset component will be stretched and produce elastic deformation.

[0075] When the placement mechanism pulls the traffic cone out of the clamping channel, the reset component retracts to its original length, causing the first and second claw plates to rotate in opposite directions, restoring the radius of the clamping channel to its initial radius. This greatly improves the stability of the traffic cone conveying without affecting the conveying of other traffic cones. After the traffic cone is clamped vertically with its cone facing downwards by the claw assembly, it is then conveyed to the corresponding position of the placement mechanism by the conveying component. This avoids the situation where a single traffic cone falling over on the conveyor belt can easily cause other traffic cones to fall over together, delaying the subsequent placement of traffic cones. It solves the problem of belt conveying being greatly affected by the inertia of the conveyor drive components. It has the advantages of being easy to use, simple to operate, low in implementation cost, and easy to promote and implement.

[0076] Preferably, the conveying assembly C1 includes a conveying table C10, a conveying guide rail C11 on the conveying table C10, a conveying seat C12 on the conveying guide rail C11, and a conveying drive assembly C13 on the conveying table C10. The gripper assembly C21 is disposed on the conveying seat C12, and the conveying drive assembly C13 is used to drive the conveying seat C12 to slide along the conveying guide rail C11.

[0077] In actual implementation, the conveyor rail is racetrack-shaped, and the conveyor seat can slide around the conveyor rail. The road cone is held vertically with the cone facing downward by the gripper assembly, and then conveyed to the corresponding position of the placement mechanism by the conveyor assembly. This avoids the situation where a single road cone falls on the conveyor belt and causes other road cones to fall together, thus delaying the subsequent placement of road cones. It solves the problem that belt conveying is greatly affected by the inertia of the conveyor drive component. It has the advantages of being easy to use, simple to operate, low implementation cost, and easy to promote and implement.

[0078] Preferably, an outer pulley C14 is provided on one side of the bottom of the conveying seat C12, and an inner pulley C15 is provided on the other side at a distance from the outer pulley C14. The conveying guide rail C11 is located between the outer pulley C14 and the inner pulley C15, and the inner pulley C15 and the outer pulley C14 can slide along the conveying guide rail C11.

[0079] Preferably, the conveying guide rail C11 includes a guide rail body C110 disposed on the conveying table C10, an outer conveying guide rail C111 disposed outside the guide rail body C110, and an inner conveying guide rail C112 disposed inside the guide rail body C110. The outer pulley C14 is slidably disposed on the outer conveying guide rail C111, and the inner pulley C15 is slidably disposed on the inner conveying guide rail C112.

[0080] In actual implementation, the stability of the conveyor seat sliding on the conveyor guide rail is improved by matching the outer guide rail with the outer pulley and the inner guide rail with the inner pulley, thus improving the conveying stability. After the road cone is clamped vertically with the cone facing downward by the gripper assembly, it is then conveyed to the corresponding position of the placement mechanism by the conveyor assembly. This avoids the situation where a single road cone falling on the conveyor belt can easily cause other road cones to fall down together, thus delaying the subsequent placement of road cones. It solves the problem that belt conveying is greatly affected by the inertia of the conveyor drive component. It has the advantages of being easy to use, simple to operate, low implementation cost, and easy to promote and implement.

[0081] Preferably, the drive assembly C13 includes a conveying drive component (not shown in the figure) disposed on the conveying table C10, a conveying gear set C131 disposed on the output end of the conveying drive component, and a conveying chain (not shown in the figure) disposed on the conveying gear set C131, and the conveying seat C12 is connected to the conveying chain.

[0082] In actual implementation, the conveyor chain can be replaced with a conveyor belt, and the conveyor drive component can be a drive motor or a drive cylinder.

[0083] Preferably, the clamping cone mechanism C2 is provided in multiple locations at intervals along the conveying guide rail C11.

[0084] More preferably, four cone clamping mechanisms C2 are provided at intervals along the conveying guide rail C11. In actual implementation, the cone is manually clamped with its cone facing downwards in the cone clamping mechanism. The conveying component circulates the cone to the corresponding position of the placement mechanism. After the placement mechanism clamps the cone out of the cone clamping mechanism, it flips the cone upside down on the ground and places it with its cone facing upwards on the ground. The clamping claws hold the cone vertically with its cone facing downwards, and then the conveying component transports it to the corresponding position of the placement mechanism. This avoids the situation where a single cone falling on the conveyor belt can easily cause other cones to fall down together, delaying the subsequent cone placement work. It solves the problem that belt conveying is greatly affected by the inertia of the conveyor drive component. It has the advantages of being easy to use, simple to operate, low implementation cost, and easy to promote and implement.

[0085] Preferably, the placement mechanism A2 includes a base A20, a connecting rod A21 rotatably disposed on the base A20, and a clamping component A22 disposed on the connecting rod A21 near one end of the conveying component C1. The clamping component A22 is used to clamp the road cone X placed vertically with its cone facing downwards. The connecting rod A21 can be flipped away from the base A20 to place the road cone X vertically with its cone facing upwards onto the ground.

[0086] This application provides an automatic traffic cone placement device, including an engineering vehicle, a placement mechanism, a traffic cone compartment, and a conveying assembly. The placement mechanism includes a base, a connecting rod, and a clamping assembly. The clamping assembly clamps the traffic cones in the traffic cone compartment vertically with the cones facing downwards, and flips them away from the base via the connecting rod, so that the traffic cones are placed on the road surface vertically with the cones facing upwards. During the clamping process, the center of gravity of the traffic cones is close to the clamping assembly, resulting in high clamping stability. The placement of the traffic cones is completed by a set of rotating joints on the connecting rod and the base, eliminating the need for multiple rotating joints for precise coordination. This device has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and ease of promotion and implementation.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
