Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance technology, and specifically relates to a traffic cone release and recovery device. Background Technology

[0002] Traffic cones, also known as road barriers, are obstacles that block road traffic. They can be used as fences or barriers in case of traffic abnormalities and are placed on roads, in dangerous areas, and in road construction sites to separate traffic flow and guide traffic. For example, during highway maintenance, it is necessary to ensure the safety of driving and the work area, so traffic cones need to be placed near the work area to guide vehicles to drive safely.

[0003] In existing technologies, road cones are generally laid manually, that is, the road cones are laid on the road surface one by one by manual operation or collected one by one by manual operation. This method is not only inefficient in laying and collecting, but also results in the road cones being placed unevenly during the laying process. It is labor-intensive, has a low safety factor, and high labor costs.

[0004] Existing technologies also employ engineering vehicles used for highway maintenance to release and retrieve traffic cones. This involves stacking traffic cones in the cargo compartment of an engineering vehicle and transporting them along a designated route to a specific location for release and retrieval. For example, utility model application number 201821882572.7 discloses a "foldable, adaptive road surface automatic traffic cone release and retrieval device." This utility model includes a frame, a tilting mechanism, a guide plate assembly, a trailer assembly, an electrical control system, a cone sleeve, and rollers. The frame is equipped with the tilting mechanism, electrical control system, and rollers. The guide plate assembly is connected to the frame via the tilting mechanism. The trailer assembly and guide plate assembly are located on the outside of the frame. The trailer assembly is located on the opposite side of the rollers. The cone sleeve is located on the opposite side of the guide plate assembly. The electrical control system includes a motor to provide power to the tilting mechanism. The tilting mechanism is driven by a motor-driven transmission shaft, which rotates the tilting shaft to retrieve or release the traffic cones from the cone sleeve. This utility model can adapt to the retrieval or release of traffic cones on uneven road surfaces. The guide plate assembly is located on the rear side of the vehicle frame and connected to the frame via a flipping mechanism. The guide plate assembly includes a crossbar, a guide plate, a stop block, and a tension spring. The bottom of the guide plate is arc-shaped. When releasing the traffic cone, the arc surface at the bottom of the guide plate is used to stand the traffic cone upright. When retrieving the traffic cone, the crossbar is used to lay the traffic cone down. However, the two guide plates on the rear side of the vehicle frame are arranged in parallel. Different traffic cones require adjustment of the distance between the stop blocks, resulting in a narrow traffic cone retrieval range. Moreover, when using this utility model, it is mounted on a pickup truck. A worker on the truck needs to place the traffic cone on the cone sleeve of the flipping mechanism before the mechanism can flip and release the traffic cone. When retrieving the traffic cone, a worker also needs to remove the traffic cone retrieved by the flipping mechanism and place it on the vehicle. Therefore, this utility model belongs to semi-automation technology with a low level of automation.

[0005] Chinese patent application CN201710899936.6 discloses an "Automatic Traffic Cone Deployment and Retrieval Vehicle Based on a Robotic Arm." This invention includes a powered, uniform-speed chassis and auxiliary equipment. The front of the chassis is equipped with left / right robotic arm pickup devices for releasing and retrieving traffic cones, left / right traffic cone lifting mechanisms for vertical raising and lowering of the cones, and a horizontal / vertical cone-shifting mechanism for lateral and longitudinal movement. The rear of the chassis is equipped with a horizontal traffic cone storage conveyor belt for storing the cones. Traffic cone guide racks are located between the front and rear wheels on both sides of the vehicle body. This invention enables fully automated placement and retrieval of traffic cones during routine highway maintenance work, reducing the workload of road maintenance workers and improving the level of automation. However, this invention has the following obvious shortcomings: First, the left / right robotic arm pickup device described in this invention is symmetrically installed on the left and right sides of the front end of the vehicle chassis, and can only pick up traffic cones in a straight line when the vehicle is moving in a straight line. It cannot pick up traffic cones when the vehicle is turning, that is, it cannot pick up traffic cones on curves; Second, the left / right robotic arm pickup device described in this invention uses a pneumatic actuator to complete the vertical lifting and lowering action. This invention uses an upper limit magnetic induction switch, a lower limit magnetic induction switch, and a pre-positioning magnetic induction switch installed to detect the vertical position of the traffic cone. The limit magnetic induction switch is responsible for lowering the traffic cone from the mechanical gripper of the horizontal / vertical cone-dispensing mechanism to the appropriate position of the left / right robotic arm pickup device during cone-dispensing operations, facilitating the insertion of the cone by the left / right robotic arm pickup device and its flipping onto the ground. During cone-collecting operations, it is responsible for vertically transporting the traffic cone from the chassis to the appropriate height of the horizontal / vertical cone-dispensing mechanism, facilitating the insertion of the cone by the horizontal / vertical cone-insertion mechanism at the bottom of the cone for subsequent cone-insertion operations by the conveyor belt storage mechanism. Therefore, the appropriate height of the horizontal / vertical cone-dispensing mechanism is fixed, i.e., during cone-dispensing or cone-collecting operations. The appropriate height for the working mechanism is fixed. Only under this appropriate height can the cone placement or collection operations be completed. If, during cone placement, the cone cannot be lowered from the mechanical gripper of the horizontal / vertical cone-shifting mechanism to the appropriate position of the left / right robotic arm pickup device, the left / right robotic arm pickup device cannot insert the cone and flip it onto the ground. Similarly, if, during cone collection, the cone cannot be vertically transported from the chassis to the appropriate height of the horizontal / vertical cone-shifting mechanism, the horizontal / vertical cone insertion mechanism cannot insert into the bottom of the cone for subsequent cleaning. In simple terms, the cone insertion operation with the storage mechanism is such that if the cone is not tilted, the left / right robotic arms cannot pick it up; moreover, if the cone is blown over by the wind or hit by a foreign object during release, the invention cannot pick it up either; thirdly, the cone guide rack of the invention is attached to both sides of the vehicle body between the front and rear wheels of the vehicle chassis, and together with the cone collection and release assembly, it remains parallel to the vehicle body. The cone guide rack is responsible for uprighting the cones during the stacking process and pushing the cones over and inserting them into the cone head during the retrieval process.Because the traffic cone guide and retraction frame is attached to both sides of the vehicle body between the front and rear wheels of the chassis, and is kept parallel to the vehicle body together with the traffic cone retraction assembly, the openings of both the traffic cone guide and retraction frame and the traffic cone retraction assembly are relatively small, and the range for picking up traffic cones is also relatively narrow. During the traffic cone retrieval operation, the guide mechanism can only normally retrieve traffic cones that are offset from the driving route by 0.5 meters to the left or right, and cannot retrieve traffic cones that are offset from the driving route by more than 0.5 meters to the left or right.

[0009] The traffic cone deployment and retraction assembly includes a combined frame.

Further, first bevel gears are mounted on the first drive shafts on both sides, and second drive shafts on both sides... A second bevel gear is mounted on the drive shaft. The first and second bevel gears form a right-angle gear transmission mechanism. The rotational motion is transmitted from the first drive shaft to the second drive shaft through the meshing of the tooth surfaces of the first and second bevel gears. First helical gears are mounted at the front and rear ends of the second drive shafts on the left and right sides, respectively. Second helical gears are mounted on four helical gear shafts. The first helical gears and the second helical gears mounted on the helical gear shafts form a worm gear transmission mechanism. The rotational motion is transmitted from the second drive shaft to the helical gear shafts through the meshing of the tooth surfaces of the first and second helical gears.

[0010] The guiding mechanism includes a double right-angle blocking frame, which consists of an upper section, a middle section, and a lower section. A guide mechanism slider that cooperates with the vertical moving guide rail on the side of the working part is installed on the left side of the upper section. A right-angle motor, the blocking frame, and guide rails are installed on the lower section. More specifically, a rotating shaft is installed on the left side of the lower section, and a right-angle motor is installed on the right side. One end of the upper part of the blocking frame is mounted on the rotating shaft, and the other end is mounted on the motor conical shaft of the right-angle motor.

[0013] Sealing plates are installed on the top of the frame and the three sides (left, right, and rear) of the structure, forming a traffic cone depot with an opening at the front.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The working part device and the guiding mechanism of this utility model can be lifted by the lifting mechanism in normal times, so that engineering vehicles can drive freely on ordinary roads, while protecting the working part device and the guiding mechanism. (2) This utility model uses a hard chain lifting mechanism to realize the lifting and lowering of the traffic cone. It has a simple structure, stable operation, and high reliability. (3) The road cone release and take-up assembly of this utility model adopts a spiral material distribution method, that is, on the combined frame, a servo motor, a right-angle gear transmission mechanism and a worm gear mechanism drive four spiral wheels to move diagonally synchronously, so that the road cone release and take-up mechanism can rotate synchronously, avoiding asynchronous jamming. (4) The horizontal roller conveyor group and the inclined roller conveyor group of the road cone receiving and releasing roller conveyor of this utility model both adopt electric roller group and follower roller group. The electric roller transmits power to the follower roller, realizing the synchronization of forward and reverse rotation of the horizontal roller conveyor group and the inclined roller conveyor group. The operation is reliable and can avoid the motor being damaged by overload impact in the vehicle bumpy environment. (5) This utility model uses the cooperation of the working part moving slider and the working part longitudinal moving guide rail to realize the longitudinal movement of the working part device, realize the curved placement of the road cone, and meet the needs of use in different environments; (6) The lower end of the blocking frame of this utility model is provided with an arc-shaped blocking surface, which is conducive to gradually tilting the upright road cone during the reversing process, guiding the road cone to the road cone collection and release roller conveyor in sequence. The blocking frame passes over and leaves the road cone during the rotation process, and the road cone returns to the vertical state, which facilitates the subsequent hard chain lifting mechanism to realize the lifting and lowering of the road cone. (7) The guide flow strip of this utility model is installed in the shape of a trumpet on the left and right sides of the lower section of the double right-angle block frame. Its opening angle is adjustable, and the range of picking up the road cone is wider, which is conducive to picking up the road cone. Moreover, the guide flow strips on the left and right sides can be folded and stored to reduce the space occupied by the vehicle and avoid damage in case of misoperation. Attached Figure Description

[0017] like Figures 1-4 As shown, the technical solution adopted by this utility model includes a frame 1, on which a traffic cone storage 2 for storing traffic cones and a working part device 3 containing traffic cone receiving and discharging components are installed. On the working part device 3, a guiding mechanism 4 containing a blocking frame and a guide flow strip and a traffic cone receiving and discharging roller conveyor 5 containing a hard chain lifting mechanism are installed. The frame 1 includes a frame base 1-1 for connection with the vehicle chassis, frame columns 1-2, frame top frame 1-3, and frame diagonal support columns 1-4. The frame base 1-1, frame columns 1-2, frame top frame 1-3, and frame diagonal support columns 1-4 are connected to form an integral frame. Two frame top frame longitudinal beams 1-3-1 extend from the right side of the frame top frame 1-3 of the frame 1. Diagonal support columns 1-5 are provided between the front and rear two right side frame top frame longitudinal beams 1-3-1 and the front and rear two right side frame columns 1-2. Longitudinal moving guide rails 1-6 of the working part are installed on the left and right frame top frame longitudinal beams 1-3-1. Furthermore, a traffic cone storage unit 2 is installed on the frame base 1-1. Three to five sets of ramp belt mounting supports 2-1 are installed on the frame base 1-1. Three to five horizontally placed traffic cone storage belt conveyors 2-2 are installed on the three to five sets of ramp belt mounting supports 2-1. Each traffic cone storage belt conveyor 2-2 includes a traffic cone storage ramp belt 2-2-1. Although the traffic cone storage ramp belt 2-2-1 is horizontally placed without any inclination, multiple traffic cone baffle strips 2-2-2 are fixed at intervals on the traffic cone storage ramp belt 2-2-1, perpendicular to the conveying direction of the traffic cone storage belt conveyor 2-2. These traffic cone baffle strips 2-2-2 are used to prevent the traffic cones from moving along the traffic cone storage ramp belt 2-2, thus avoiding damage to the traffic cones. The traffic cone storage 2 includes 3 to 5 traffic cone storage belt conveyors 2-2. Each traffic cone storage ramp 2-2-1 can store 3 to 5 rows, 7 grids per row, and each grid can hold a set of 12 traffic cones. The total traffic cone storage capacity of the 3 to 5 horizontally placed traffic cone storage ramps 2-2 is 200 to 400, which can meet the needs of traffic cone release and retrieval work for general highway maintenance. The working part device 3 is installed on the longitudinal moving guide rail 1-6 of the working part installed on the longitudinal beams 1-3-1 of the top frame on the left and right sides. like Figures 5-8 and combined Figures 1-4 As shown, the working unit device 3 includes a frame consisting of a working unit support column 3-1, a working unit support top beam 3-2, and a working unit support bottom beam 3-3. The crossbeam of the working unit support top beam 3-2 extends to the left and is supported by a working unit support inclined column 3-4. Two sliding block seats 3-5 are installed on the working unit support top beam 3-2. Longitudinal moving sliding blocks 3-6 are installed below the left and right ends of the two sliding block seats 3-5 respectively. The working unit device 3 is connected to the working unit longitudinal moving guide rail 1-6 of the frame 1 through the working unit longitudinal moving sliding blocks 3-6. A sliding block moving motor 3-7 is also installed on the working unit support top beam 3-2. Driven by 3-7, the working part device 3 performs longitudinal linear reciprocating motion on the frame 1 corresponding to the road cone storage belt conveyor 2-2 of the road cone warehouse 2; a telescopic belt conveyor 3-8 for transferring road cones and a road cone take-up and release assembly 3-9 are installed on the bottom beam 3-3 of the working part support; a vertical moving guide rail 3-10 for the working part is installed on the working part support column 3-1; furthermore, a front vertical moving guide rail 3-10-1 for cooperating with the road cone take-up and release roller conveyor 5 is installed in front of the working part support column 3-1; a side vertical moving guide rail 3-10-2 for cooperating with the guide mechanism 4 is installed on the right side of the working part support column 3-1; like Figures 9-12 and Figure 18As shown, the traffic cone deployment and retraction assembly 3-9 includes a combined frame 3-9-1. A motor frame 3-9-2 is installed at the rear center of the combined frame 3-9-1. A servo motor 3-9-3 is installed in the motor frame 3-9-2. First drive shafts 3-9-5 are connected to both sides of the servo motor 3-9-3 via couplings 3-9-4. Second drive shafts 3-9-10 are installed on both sides of the combined frame 3-9-1. Four helical wheels 3-9-7 are symmetrically mounted on the combined frame 3-9-1 via four helical wheel shafts 3-9-6. A right-angle gear transmission mechanism 3-9-9 and a worm gear transmission mechanism 3-9-9 are installed between the first drive shafts 3-9-5 and the helical wheel shafts 3-9-6. 8. Further, a first bevel gear 3-9-9-1 is installed on the first drive shaft 3-9-5 on both the left and right sides, and a second bevel gear 3-9-9-2 is installed on the second drive shaft 3-9-10 on both the left and right sides. The first bevel gear 3-9-9-1 and the second bevel gear 3-9-9-2 form a right-angle gear transmission mechanism 3-9-9. Through the meshing of the tooth surfaces of the first bevel gear 3-9-9-1 and the second bevel gear 3-9-9-2, the rotational motion is transmitted from the first drive shaft 3-9-5 to the second drive shaft 3-9-10. A first helical gear 3-9-8-1 (equivalent to a worm gear) is installed at the front and rear ends of the second drive shaft 3-9-10 on both the left and right sides. Four helical gear shafts 3-9-6 are fitted with... The second helical gear 3-9-8-2 (equivalent to a worm) forms a worm gear transmission mechanism 3-9-8, consisting of the first helical gear 3-9-8-1 (equivalent to a worm wheel) and the second helical gear 3-9-8-2 (equivalent to a worm) mounted on the solenoid shaft 3-9-6. Through the meshing of the teeth of the first helical gear 3-9-8-1 and the second helical gear 3-9-8-2, rotational motion is transmitted from the second transmission shaft 3-9-10 to the solenoid shaft 3-9-6. During operation, the servo motor 3-9-3 drives the first transmission shafts 3-9-5 on both sides to rotate in opposite directions via the coupling 3-9-4. The first bevel gears 3-9-9-1 mounted on the first transmission shafts 3-9-5 on both sides rotate accordingly, driving the gears mounted on the left and right sides... The second bevel gears 3-9-9-2 on the second drive shafts 3-9-10 on both sides rotate, which in turn drives the first helical gears 3-9-8-1 at the front and rear ends of the second drive shafts 3-9-10 on both sides to rotate. The four first helical gears 3-9-8-1 drive the four second helical gears 3-9-8-2 to rotate respectively. This enables the servo motor 3-9-3 to drive the first drive shaft 3-9-5 through the coupling 3-9-4. The first drive shaft 3-9-5 drives the four helical gear shafts 3-9-6 to rotate in opposite directions through the right-angle gear transmission mechanism 3-9-9 and the worm gear transmission mechanism 3-9-8. This enables the four helical gears 3-9-7 to rotate in opposite directions. When the road cone is released, the servo motor 3-9-3 rotates forward.The servo motor 3-9-7 rotates in pairs in opposite directions to release individual traffic cones from a group; when retrieving traffic cones, the servo motor 3-9-3 reverses, driving the four helical wheels 3-9-7 to rotate in pairs in opposite directions to retrieve the traffic cones as a group. like Figures 13-14 and Figure 19 As shown, the guiding mechanism 4 includes a double right-angle blocking frame 4-1, which is composed of an upper section 4-1-1, a middle section 4-1-2, and a lower section 4-1-3. A guide mechanism sliding block 4-2, which cooperates with the vertical moving guide rail 3-10-2 on the side of the working part, is installed on the left side of the upper section 4-1-1. A right-angle motor 4-3, a blocking frame 4-4, and a guide flow strip 4-5 are installed on the lower section 4-1-3. Further, a rotating shaft 4-9 is installed on the left side of the lower section 4-1-3, and a right-angle motor 4-3 is installed on the right side. The right-angle motor 4-3 includes a motor housing 4-3-2 and a motor conical shaft 4-3-1. The upper end of the blocking frame 4-4... The obstruction frame 4-4 is mounted on the rotating shaft 4-9 at one end and on the motor conical shaft 4-3-1 of the right-angle motor 4-3 at the other end. It is secured to the motor conical shaft 4-3-1 and the rotating shaft 4-9 by a pressure plate 4-7 and a locking nut 4-8. During operation, the motor conical shaft 4-3-1 of the right-angle motor 4-3 rotates, causing the rotating shaft 4-9 to rotate. Since the obstruction frame 4-4 is secured to both the motor conical shaft 4-3-1 and the rotating shaft 4-9, the rotation of the motor conical shaft 4-3-1 simultaneously drives the obstruction frame 4-4 and the rotating shaft 4-9 to rotate together. The flipping of the obstruction frame 4-4 guides the traffic cone onto the traffic cone collection and dispensing roller conveyor 5. The guide flow strip 4-5 guides the traffic cone within the space of the obstruction flap 4-4 and into contact with it. To facilitate the pickup of traffic cones, the guide flow strips 4-5 are installed in a trumpet shape on the left and right sides of the lower section 4-1-3 of the double right-angle barrier. The opening angle is adjustable. Furthermore, the guide flow strips 4-5 are connected to the lower section 4-1-3 of the double right-angle barrier via hinges 4-6, which allows the guide flow strips 4-5 on the left and right sides to be folded and stored, reducing the space occupied by vehicles and avoiding damage in case of misoperation.

[0018] The lower end of the blocking frame 4-4 is provided with an arc-shaped blocking surface 4-4-1. Further, as... Figure 20As shown, the blocking frame 4-4 includes a left upright 4-4-2, a right upright 4-4-3, an upper crossbar 4-4-4, and a U-shaped reinforcing rib 4-4-7 with a horizontal bottom and an opening on the right side, all welded together. A right hollow cylinder 4-4-5 and a left hollow cylinder 4-4-6 are respectively located at the upper ends of the left upright 4-4-2 and the right upright 4-4-3. The blocking frame 4-4 is mounted on the rotating shaft 4-9 via the left hollow cylinder 4-4-6, and on the motor conical shaft 4-3 of the right-angle motor 4-3 via the right hollow cylinder 4-4-5. On 1, an arc-shaped blocking surface 4-4-1 is welded inside the opening on the right side of the U-shaped reinforcing rib 4-4-7. When releasing the traffic cone, the blocking frame 4-4 rotates counterclockwise under the drive of the right-angle motor 4-3, using the arc-shaped blocking surface 4-4-1 to stand the traffic cone upright. When retrieving the traffic cone, the blocking frame 4-4 rotates clockwise under the drive of the right-angle motor 4-3, gradually tilting the upright traffic cone during the reversing process. That is, during the flipping process, the blocking frame 4-4 gradually guides the traffic cone onto the traffic cone collection and release roller conveyor 5 and then gradually leaves the traffic cone, and the traffic cone returns to the vertical state. like Figure 15 and Figure 16 As shown, the traffic cone receiving and releasing roller conveyor 5 includes a roller frame 5-1. A horizontal roller group 5-2 and an inclined roller group 5-3 are installed on the horizontal surface of the roller frame 5-1. Each of the horizontal roller group 5-2 and the inclined roller group 5-3 has an electric roller group and a follower roller group. A notch is opened in the middle of the horizontal roller group 5-2. A rigid chain lifting mechanism 5-4 and a gripper 5-5 are installed at the middle notch of the horizontal roller group 5-2 on the roller frame 5-1. When releasing the traffic cone, the rigid chain lifting mechanism 5-4 drives the gripper 5-5 to lift it into position. The traffic cones are then picked up sequentially by the traffic cone receiving and releasing assembly 3-9. After picking up the traffic cones, the rigid chain lifting mechanism 5-4 descends to its position, sequentially placing the traffic cones onto the traffic cone receiving and releasing roller conveyor 5. The forward rotation of the horizontal roller group 5-2 and the inclined roller group 5-3 achieves the individual release of the group of traffic cones. When the traffic cones are being retrieved, the rigid chain lifting mechanism 5-4 and the gripper 5-5 are positioned below the horizontal roller group 5-2. The traffic cones are guided sequentially onto the traffic cone collection and release roller conveyor 5 by the guide flow bar 4-5 and the blocking frame 4-4 of the guide mechanism 4. After the reverse rotation of the inclined roller group 5-3 and the horizontal roller group 5-2, the traffic cones are transported above the gripper 5-5. The rigid chain lifting mechanism 5-4 then rises and sends the traffic cones to the collection position of the traffic cone collection and release assembly 3-9. The traffic cone collection and release assembly then operates, realizing the group retrieval of the traffic cones.

[0019] like Figure 17 , combined Figures 1 to 16 As shown, in use, this utility model is connected to the frame base 1-1 Connected to the chassis 6 of the engineering vehicle used for highway maintenance, sealing plates 2-3 are installed on the frame of the frame 1 and on the left, right and rear three sides, forming a road cone storage 2 with an opening at the front. A touch screen for sending operation commands is installed in the driver's cab of the engineering vehicle. Its working process is as follows: When releasing traffic cone 7, the engineering vehicle travels to the work section and stops at the starting point. The spacing and type of the released traffic cones are set on the touchscreen and confirmed. The touchscreen displays "Ready to begin," and the vehicle starts traveling at the prescribed speed and route. The traffic cone storage ramp 2-2 and telescopic belt conveyor 3-8 place groups (12 cones per group) of traffic cone 7 onto the traffic cone release assembly 3-9. The rigid chain lifting mechanism 5-4 drives the grab handle 5-5 to rise, waiting in the receiving position for the traffic cone release assembly 3-9 to release the traffic cone 7. At this time, the servo motor 3-9-3 rotates forward, driving the first drive shaft 3-9-5 through the couplings 3-9-4 on both sides. The first drive shaft 3-9-5, through the right-angle gear transmission mechanism 3-9-9 and the worm gear transmission mechanism 3... -9-8 drives the four helical wheel shafts 3-9-6 to rotate in opposite directions in pairs, thereby realizing the individual release of the group of road cones by the four helical wheels 3-9-7 rotating in opposite directions in pairs. After the road cone 7 is sent to the rigid chain lifting mechanism 5-4, the rigid chain lifting mechanism 5-4 descends and places the road cone 7 on the road cone take-up and release roller conveyor 5. The horizontal roller group 5-2 and the inclined roller group 5-3 of the road cone take-up and release roller conveyor 5 rotate forward to release the individual road cone 7. Under the action of multiple forward rotations of the servo motor 3-9-3, the group of road cones 7 are placed on the road surface in sequence. If curved placement is required, the working part device 3 drives the working part to move longitudinally through the sliding of the working part longitudinal moving slider 3-6 on the working part longitudinal moving guide rail of the frame 1, so as to realize curved placement in coordination with the vehicle movement. When retrieving traffic cone 7, first ensure that traffic cone 7 is upright on the road surface. Adjust the two guide flow strips 4-5 to their maximum opening. The driving route of the engineering vehicle should ensure that traffic cone 7 is received by the guide flow strips 4-5 of the guide mechanism 4. Set and confirm the traffic cone retrieval option on the touch screen. Under the push of the guide flow strips 4-5, the traffic cone 7 on the road surface is guided to the retrieval line. Traffic cone 7 is gradually tilted by the blocking frame 4-4 during the flipping process. When traffic cone 7 is tilted to the correct position at 40° to 45°, it is gradually guided by the inclined roller group 5-3 to the horizontal roller group 5-2 to the top of the rigid chain lifting mechanism 5-4 and the grabber 5-5. At this time, the blocking frame 4-4 passes over and moves away from traffic cone 7 during the rotation. Traffic cone 7 is then supported by its center of gravity. The cones naturally return to an upright position. At this time, the rigid chain lifting mechanism 5-4 rises and sends the cone 7 to the cone take-up and put-down assembly 3-9. The servo motor 3-9-3 reverses, driving the four solenoid wheels 3-9-7 to rotate in opposite directions. The cone take-up and put-down assembly 3-9 picks up the cone 7 and sets the cones 7 into groups in sequence (each subsequent cone 7 is set on each previous cone 7, with 12 cones per group). Then, the telescopic belt conveyor 3-8 is used to transfer the cones, and the cone storage ramp belt 2-2 reverses to put the cones into storage.

[0020] During release or retrieval, the working part 3 and the guiding mechanism 4 can be retracted to adapt to the switching between working state and ordinary road driving state.
