Description

Technical Field

[0001] The invention relates to the field of engineering vehicles, in particular to an automatic safety cone retractable vehicle. Background Art

[0002] With the development of society, the placement of traffic cones during maintenance work on roads and highways in my country is gradually being replaced by automation, replacing manual operations. Various manufacturers are continuously increasing their research and development of automatic retractable traffic cones.

[0003] On June 1, 2016, Chinese Patent Publication No. CN205276159U disclosed an automatic traffic cone retracting and deploying vehicle, comprising a truck chassis, a grabbing arm mounted on the chassis, a cone stacking device, cones, a mounting assembly, a cone delivering device, a cone shifting device, and a cone erecting device; the grabbing arm is arranged at the front of a temporary cone storage area, the cone stacking device is arranged between a cone bin and the temporary cone storage area, the cone delivering device is arranged at the lower part of the cone bin, the cone delivering device transports traffic cones forward to the cone stacking device, the cone shifting device is arranged at the lower part of the temporary cone storage area, the cone stacking device grabs the first row of cones and conveys them forward to the cone shifting device, the cone shifting device transfers five cones in the same row one by one horizontally to the grabbing arm, the grabbing arm grabs each traffic cone from the chassis and places it on the road surface on the side of the vehicle, and the cone erecting device is arranged on one side of the chassis to shift the horizontally lying cones to an upright state. Since the cone device is arranged on the chassis, the chassis of a general vehicle is relatively low and is not suitable for placing or retrieving a large safety cone.

[0004] On July 6, 2016, Chinese Patent Publication No. CN105735166A disclosed an automatic traffic cone retracting vehicle. The vehicle comprises a vehicle body, a placing device, a retrieval device, and an intelligent control cabinet. Both the placing device and the retrieval device are connected to the intelligent control cabinet. The placing device comprises a manipulator, an automatic lifting assembly, and a forklift assembly. The automatic lifting assembly is mounted on the vehicle's floor, upon which multiple traffic cones are placed. The manipulator is mounted on the vehicle's inner sidewall and is used to transfer the traffic cones from the automatic lifting assembly to the forklift assembly, which is mounted on the outside of the vehicle's rear fender and is used to place the cones on the road surface. The retrieval device is mounted on the outside of the vehicle body and comprises a conveyor belt assembly for transporting the cones into the vehicle body, and a retrieval rod for moving the cones from the road surface onto the conveyor belt assembly. The retrieval method is relatively cumbersome, and in practice, it is difficult to accurately retrieve the traffic cones located on the ground.

[0005] On July 30, 2014, Chinese Patent Publication No. CN203741743U disclosed a manipulator for grasping traffic cones. The manipulator comprises a mechanical arm, a cylinder, a lower jaw, and an upper jaw. The cylinder body is fixed to the mechanical arm, and the extended end of the cylinder piston rod is connected to the lower jaw, which rotates around a bearing seat, via a universal joint. The upper jaw is fixed to the mechanical arm, and the lower jaw and upper jaw engage to clamp the traffic cone. When the manipulator grasps a traffic cone and pulls it backward, it easily pulls out the previous cone.

[0006] On January 7, 2015, Chinese Patent Publication No. CN204080673U disclosed a fully automatic traffic cone retracting and deploying device. The device is mounted at the rear end of a traveling mechanism and includes an inclined belt frame with a belt drive mechanism. The front end of the belt frame is provided with a front guide rod and a shift rod, with the front guide rod positioned forward of the shift rod. While the retracting and deploying device is relatively simple, it is not stable in placement.

[0007] In view of this, the present invention provides a new automatic safety cone retractable vehicle to solve the above problems. Summary of the Invention

[0037] The present invention will be described in detail below with reference to the accompanying drawings. However, it should be emphasized that the following embodiments are merely exemplary and are not intended to limit the scope and application of the present invention.

[0038] Please see Figures 2 to 20 The present invention is an automatic retractable safety cone vehicle, which includes a vehicle body 1 and a storage device 2, a clamping device 3, a transfer device 4, a conveying device 5 and a retractable device 6 installed on the vehicle body 1.

[0039] The vehicle body 1 is a modified truck, and the storage device 2 is installed in the cargo box at the rear of the truck. The storage device 2, the clamping device 3, the transfer device 4, the conveying device 5 and the retracting device 6 are sealed by setting door locks around the cargo box.

[0040] The storage device 2 is used to store safety cones, which includes a base plate 21 fixed to the vehicle body 1 and a support frame 22 fixed above the base plate 21. The support frame 22 is a truss structure composed of a number of support rods extending vertically, horizontally, and longitudinally and fixed to each other. Figure 1 , which includes a base and a cone above the base.

[0041] refer to Figures 2 to 7 As shown, the storage device 2 also includes a transmission mechanism 23 fixed to the support frame 22 and a drive mechanism 24 fixed to the base plate 21. The safety cones are stored in the transmission mechanism 23. The transmission mechanism 23 includes a fixed rod 231 fixed to the support frame 22 and parallel to each other, two pairs of bearing seats 232 fixed to the ends of the fixed rod 231, transmission bearings (not shown) fixed in the bearing seats 232, a transmission shaft 233 accommodated in the transmission bearings, and a gear 234 fixed to one of the transmission shafts 233. The transmission mechanism 23 also includes a plurality of transmission wheels 235 fixed to the transmission shafts 233 and a transmission belt 236 connecting the transmission wheels 235. The transmission belt 236 is a belt or chain, and the transmission wheel 235 is a pulley or sprocket.

[0042] Several retaining bars 237 are arranged on the transmission belt 236 and fixed to the transmission belt 236 at intervals. The retaining bars 237 include a first fixing portion 2371 fixed to the transmission belt 236, a first connecting portion 2372 extending vertically upward from one side of the first fixing portion 2371, and a first retaining portion 2373 extending in a curved manner from the end of the first connecting portion 2372. The first retaining portion 2373 extends toward the other side of the first fixing portion 2371. The base of the safety cone is longitudinally retained between two adjacent first retaining portions 2373. The outer surface of the junction between the first connecting portion 2372 and the first retaining portion 2373 is arc-shaped, allowing the safety cone to slide smoothly downward between the two first retaining portions 2373.

[0043] The gear 234 is connected to the driving mechanism 24, and the driving mechanism 24 is a motor 241 and a chain 242 installed on the motor, and the chain 242 connects the gear 234 and the motor 241. By driving the motor 241, the motor 241 drives the transmission mechanism 23 to rotate.

[0044] The storage device 2 also includes an adjustment mechanism 25 for adjusting the tension of the transmission belt 236. The adjustment mechanism 25 includes an adjustment block 251 fixed to the fixed rod 231 and having a threaded hole, an adjustment screw 252 received in the threaded hole, and a bearing seat 232 connected to the adjustment screw 252. The bearing seat 232 is fixed to the fixed rod 231 via a screw and an adjustment hole. The distance between the bearing seat 232 and the fixed rod 231 can be determined by adjusting the screw and the adjustment hole. By rotating the adjustment screw 252, the distance between the bearing seat 232 at both ends of the fixed rod 231 is determined, ensuring that the transmission belt 236 is kept at a suitable tension.

[0045] In the present invention, there are two transmission mechanisms 23, which are arranged in the vertical direction of the support frame 22. The two transmission mechanisms 23 are driven by two drive mechanisms 24, respectively. The drive mechanisms 24 are not limited to being directly fixed to the base plate 21, but can be indirectly fixed to the base plate 21. The drive mechanisms 24 can be fixed to the base plate 21 via a fixing platform 26, and the drive mechanisms 24 can be indirectly fixed to the base plate 21 by fixing the fixing platform 26.

[0046] Storage device 2 also includes at least one guide rod 27 fixed to support frame 22. Guide rods 27 are located on the fixed support rods, parallel to each other and spaced apart by a distance equal to the width of the safety cone base. Guide rods 27 are suspended above retaining bars 237. When retaining bars 237 of transmission mechanism 23 move, guide rods 27 maintain stable forward and backward movement of the safety cone.

[0047] Combine Figures 13 to 15 As shown, the gripping device 3 is mounted on the support frame 22 of the storage device 2 and includes an X-axis drive assembly 31 and a Z-axis drive assembly 32. The X-axis drive assembly 31 includes an X-axis frame 311, a pair of X-axis slide rails 313 fixed to the support frame 22, X-axis sliders 312 movably connected to the X-axis slide rails 313, an X-axis rack 314 extending parallel to the X-axis slide rails 313, an X-axis motor 315 fixed to the X-axis frame 311, and an X-axis gear 316 mounted on the X-axis motor 315 and mated with the X-axis rack 314. The X-axis rack 314 extends laterally, and when the X-axis motor 315 is activated, the X-axis motor 315 rotates the X-axis gear 316, which then drives the X-axis frame 311 to slide along the X-axis slide rails 313 in the direction in which the X-axis rack 314 extends.

[0048] The Z-axis drive assembly 32 includes a Z-axis motor 321 fixed to the X-axis frame 311, a Z-axis output pulley 322 installed on the Z-axis motor 321, a Z-axis input pulley 323 fixed to the X-axis frame 311, a Z-axis belt 324 connecting the Z-axis output pulley 322 and the Z-axis input pulley 323, a Z-axis screw rod 325 fixedly connected to the Z-axis input pulley 323, and a Z-axis sliding block 326 fixed on the Z-axis screw rod 325.

[0049] The Z-axis screw rod 325 extends vertically, and its two ends are sleeved on bearings, which are sleeved on bearing seats, and the bearing seats are fixed to the X-axis frame 311. The Z-axis motor 321 drives the Z-axis screw rod 325 to rotate, and the Z-axis screw rod 325 drives the Z-axis sliding block 326 to move up and down.

[0050] The clamping device 3 also has a clamping assembly 33 fixed on the Z-axis sliding block 326. The clamping assembly 33 includes a clamping frame 331 fixed on the Z-axis sliding block 326, a clamping slider 332 fixed on the clamping frame 331, a clamping support frame 333 fixed on the clamping frame 331, a clamping cylinder 334 fixed on the clamping support frame 333, a first clamping block 335 connected to the clamping cylinder 334, and a clamping slide rail 336 fixed on the clamping frame 331 and extending vertically.

[0051] The clamping frame 331 is a plate-like or frame-like structure, fixed to the Z-axis slide block 326. The Z-axis drive assembly 32 drives the clamping assembly 33 up and down. The clamping slide 332 mates with the clamping rail 336. A pair of clamping support frames 333 are located on either side of the clamping frame 331, extending obliquely upward from the clamping frame 331. A clamping cylinder 334 is fixed to the top of the clamping support frames 333.

[0052] The first clamping block 335 is pivotally connected to the lower end of the clamping frame 331, and the clamping cylinder 334 extends obliquely downward. The first clamping block 335 is connected to the clamping cylinder 334. By starting the clamping cylinder 334, the first clamping block 335 can rotate around an axis.

[0053] The first clamping block 335 is L-shaped and includes a second fixing portion 3351, a first clamping portion 3352 perpendicular to the second fixing portion 3351, and a second connecting portion 3353 connected to the clamping cylinder 334. The second fixing portion 3351 has receiving holes 3354 extending through both sides thereof. A clamping shaft 3355 is received in the receiving holes 3354 and connected to the clamping frame 331. The second connecting portion 3353 extends upward from the surface of the second fixing portion 3351 and is connected to the clamping cylinder 334 via a connecting shaft 3356.

[0054] Initially, the second fixing part 3351 is in a horizontal position and the first clamping part 3352 is in a vertical position. When the safety cone needs to be clamped, the clamping cylinder 334 is started, and the clamping cylinder 334 applies a thrust to the first clamping block 335. The first clamping block 335 rotates around the clamping rotation axis 3355, and the first clamping part 3352 is tilted upward from the vertical position.

[0055] The clamping assembly 33 further includes a second clamping block 337 fixed to the surface of the clamping frame 331 . The second clamping block 337 includes a third fixing portion 3371 fixed to the clamping frame 331 and a second clamping portion 3372 extending obliquely from the end of the third fixing portion 3371 .

[0056] The third fixing portion 3371 has adjustment holes 3373 extending through its front and rear surfaces. These holes receive bolts that secure the third fixing portion 3371 to the surface of the clamping frame 331. The adjustment holes 3373 are elongated slots that allow for adjustment of the position of the second clamping block 337 as needed. The second clamping portion 3372 extends obliquely downward from the third fixing portion 3371.

[0057] The second clamping portion 3372 is located above the first clamping block 335 .

[0058] A third fixing portion 3371 is connected to the plurality of second clamping portions 3372 . A gap 3374 is defined between the plurality of second clamping portions 3372 . The gap 3374 is an arc structure.

[0059] When the safety cone needs to be clamped, the X-axis motor 315 and the Z-axis motor 321 are activated to move the clamping assembly 33 to the designated position. The Z-axis motor 321 drives the clamping frame 331 downward, and the second clamping portion 3372 moves downward along the upper surface of the safety cone base (the safety cone base is horizontally positioned) until the gap 3374 between the second clamping portions 3372 contacts the surface of the safety cone (there is a distance between the base of the previous safety cone and the base of the next safety cone, which is the horizontal dimension of the second clamping portion 3372). At this point, the first clamping portion 3352 is in a vertical position. Because the second clamping portion 3372 extends obliquely downward, the first clamping portion 3352 and the second clamping portion 3372 form a certain angle, which holds the safety cone base. The X-axis motor 315 again drives the clamping assembly 33 forward, bringing the first clamping portion 3352 closer to the bottom of the safety cone base. The clamping cylinder 334 is activated, causing the first clamping block 335 to rotate. The first clamping portion 3352 rotates from a vertical position to a horizontal position, extending into the hollow center of the safety cone. The first clamping portion 3352 then tilts upward, and the first clamping portion 3352 and the second clamping portion 3372 jointly clamp the safety cone. The X-axis motor 315 is then activated, causing the entire clamping assembly 33 to move backward, thereby removing the safety cone.

[0060] In this embodiment, the clamping assembly 33 includes multiple first clamping blocks 335 and corresponding second clamping blocks 337, allowing for simultaneous removal of multiple safety cones. This improves safety cone removal efficiency. The storage device 2 stores the safety cones in equal columns.

[0061] The clamping device 3 also includes an auxiliary assembly 34 mounted on the support frame 22. The auxiliary assembly 34 includes a pair of blocking cylinders 341 mounted on the support frame 22 and a blocking rod 342 mounted on the blocking cylinders 341. The blocking rod 342 is located in front of the clamping assembly 33. When the first clamping portion 3352 and the second clamping portion 3372 jointly clamp the safety cone, the blocking cylinder 341 is initially positioned below the safety cone. When the blocking cylinder 341 is activated, it pushes the blocking rod 342 upward, pushing the blocking rod 342 behind the base of the clamping safety cone and in front of the base of the next safety cone. When the blocking cylinder 341 and the entire clamping assembly 33 retreat, the next safety cone to be clamped is blocked by the blocking rod 342. After the first safety cone is clamped away, the blocking rod 342 returns to its initial position. The provision of the auxiliary assembly 344 ensures that the subsequent safety cone is not dragged out when the previous one is dragged.

[0062] Reference Figures 8 to 12 As shown, the transfer device 4 is installed on the vehicle body 1 or the bottom plate 21 and is located below the clamping device 3. The safety cone clamped by the clamping assembly 33 is placed in the transfer device 4.

[0063] The transfer device 4 includes a fixed platform 41 and a placement platform 42 located on both sides of the fixed platform 41. In this embodiment, the placement platform 42 is a U-shaped bar 421 installed on the fixed platform 41, a plurality of rollers 422 located on the U-shaped bar 421, and a fixing member 423 fixed to the U-shaped bar 42 and connected to the rollers 422. The rollers 422 can rotate around the fixing member 423, and the plurality of rollers 422 are arranged in a row. The transfer device 4 also has a transfer motor (not shown) installed on the fixed platform 41. The transfer motor (not shown) is connected to a transfer chain (not shown). The transfer chain (not shown) is connected to the rollers 422, and the rollers 422 are driven to rotate by the transfer motor (not shown). Since the technology of driving the rollers 422 by the motor and connecting the chain to promote the rolling of the rollers 422 is a common existing technology, it will not be described in detail here.

[0064] The two rows of placement platforms 42 have different heights, which are set according to the size of the safety cones to ensure that the base and cone body of the safety cones can be stably placed on the placement platforms 42. This side has a baffle 44 extending upward from the fixed platform 41 to prevent the safety cones from sliding off.

[0065] When the safety cone is placed on the placement platform 42 , the transfer motor (not shown) drives the roller 422 to rotate, and the roller 422 drives the safety cone to move toward one side of the placement platform 42 .

[0066] Since multiple safety cones are simultaneously captured and placed side by side on the placement table 42, the following situation may occur with the safety cones: the multiple safety cones move simultaneously in the same direction, potentially causing a jam at the rear end of the placement table 42. To overcome this jam, which would hinder the operation of the next step, the fixed table 41 has mounting holes 411 extending through the upper and lower surfaces. The mounting holes 411 may also extend through the base plate 21. The transfer device 4 also has a lifting assembly 45 within the mounting holes 411. The lifting assembly 45 includes a lifting cylinder (not shown) mounted below the fixed table 41 and a claw 451 fixed to the lifting cylinder. The claw 451 is U-shaped, and the U-shaped structure can be the same as the conical outer surface of the safety cone. When the gripping device 3 grips the safety cone and drops it downward, the lifting cylinder pushes the claw 451 upward. The claw 451 is raised to a position where, when the safety cone just lands on the placement table 42, the claw 451 just supports the safety cone. When the front safety cone is transported to the designated position, the lifting cylinder of the rear lifting assembly 45 retracts the claw 451 downward, the claw 451 disengages from the safety cone, and the safety cone is completely placed on the placement table 42. The roller 422 on the placement table 42 drives the safety cone to move forward.

[0067] The transfer device 4 also includes a flip assembly 46 mounted on the support frame 22 for erecting the safety cone placed flat on the placement table 42. The flip assembly 46 includes a flip bracket 461 fixed to the support frame 22, a flip motor 462 fixed to the flip bracket 461, a flip chain 463 connected to the flip motor 462, a flip support 464 fixed to the flip bracket 461, a flip rotation shaft assembly 466 movably fixed to the support 464 and connected to the flip chain 463, a flip connecting rod 467 fixed to the flip rotation shaft assembly 466, and a flip rod 468 fixed to the flip connecting rod 467.

[0068] The flip rotation shaft assembly 466 includes a flip rotation shaft 4661 , a flip gear 4663 mounted on the flip rotation shaft 4661 and connected to the flip chain 463 , and a bearing (not shown) mounted in the flip support 464 . The flip gear 4663 is connected to the flip motor 462 via the flip chain 463 .

[0069] The flip link 467 and the flip rotation axis 4661 are perpendicular to each other, the flip rod 468 and the flip link 467 are perpendicular to each other, and the flip rod 468 and the flip rotation axis 4661 are on the same side of the flip link 467.

[0070] A plurality of flip mounting holes 4671 are provided on the flip connecting rod 467 for adjusting the position of the flip rod 468 according to the positions of safety cones of different sizes.

[0071] When the flip motor 462 drives the flip rotating shaft group 466 to rotate through the flip chain 463, and the safety cone moves forward to the specified position through the placement platform 42, the flip motor 462 drives the flip rotating shaft 4661 and the flip rod 468 to rotate. Since the head of the safety cone exceeds the outside of the placement platform 42, the rotating flip rod 468 pushes up the head of the safety cone to make the safety cone stand up.

[0072] The flip lever 468, the flip connecting rod 467, and the flip rotation shaft 466 can be integrally formed, or they can be integrally formed in pairs, with one of the other components being mounted on the integral structure. For example, the flip rotation shaft 4661 is a separately manufactured shaft, while the flip lever 468 and the flip connecting rod 467 are integrally formed and fixed to the flip rotation shaft 4661.

[0073] The transfer device 4 also includes a pushing component 47 for pushing the safety cone. The pushing component 47 includes a transfer pushing cylinder 471 fixed to the fixed platform 41 and a transfer pushing component 472 connected to the transfer pushing cylinder 471. The pushing component 472 is used to push the erected safety cone to the next position.

[0074] The pushing component 472 includes a pushing rack 472 connected to the pushing cylinder 471 , a pushing gear 473 matched with the pushing rack 472 , a pushing rotating shaft 474 received in the pushing gear 473 , and a pushing rod 475 connected to the pushing rotating shaft 474 .

[0075] By pushing the cylinder 471, the pushing gear 473 is driven to rotate, and the pushing rod 475 is driven to rotate. In this way, the pushing rod 475 can rotate around the pushing rotation axis 474 to push the safety cone to the conveying device 5. By retracting the pushing cylinder 471, the pushing rod 475 rotates to the initial position, ready to push the next safety cone that is uprighted by the flip rod 468.

[0076] like Figure 16 The conveying device 5 is located on one side of the transfer device 4, and the safety cone is pushed to the conveying device 5 by the pushing rod 475.

[0077] The conveying device 5 includes a conveying bracket 51 and a first pulley conveyor line 52 installed on the conveying bracket 51. The safety cone is pushed onto the first pulley conveyor line 52 by the push rod 475. The first pulley conveyor line is a common existing technology. The motor drives the belt to transport the safety cone from one end of the belt to the other end. The conveying device 5 also has a blocking member 53 located above the conveying bracket 51, a push cylinder 54 installed on the blocking member 53, and a push rod 55 installed on the push cylinder 54. The blocking member 53 lies horizontally above the first pulley conveyor line 52 to prevent the safety cone from moving forward excessively. The extension direction of the push rod 55 is the same as the extension direction of the first pulley conveyor line and is perpendicular to the extension direction of the push cylinder 54. The output shaft of the jacking cylinder 54 is fixed to the conveying bracket 51, and the bottom of the jacking cylinder 54 is connected to the blocking member 53 through a slider and a slide rail. When the jacking cylinder 54 is started, the jacking cylinder 54 slides along the jacking rod 55, driving the jacking cylinder 54, the jacking rod 55 and the first pulley conveyor line 52 to run perpendicularly.

[0078] When the safety cone reaches the predetermined position, the push cylinder 54 is started, and the push cylinder 54 is started, driving the push rod 55 to push the safety cone away from the first pulley conveyor line 52 to the next position.

[0079] The conveying device 5 further includes a rotary cylinder 56 mounted on the blocking member 53 and a push-back rod 57 mounted on the rotary cylinder 56 . When the rotary cylinder 56 is started, the output shaft of the rotary cylinder 56 rotates, and the output shaft drives the push-back rod 57 to rotate.

[0080] The conveyor device 5 also includes a moving assembly 58 located on one side of the conveyor bracket 51. The moving assembly 58 includes a moving motor 581 mounted on the conveyor bracket 51, a moving chain 582 connected to the moving motor 581, a moving slider 583 fixed to the moving chain 582, and a moving bracket 584 fixed to the moving slider 583. The blocking member 53 is fixed to the moving bracket 584. The moving bracket 584 is vertically located to the side of the first pulley conveyor line 52. The moving motor 581 can pull the moving bracket 584 back and forth along the first pulley conveyor line 52 to confirm the position of the blocking member 53. A slider and a slide rail structure are provided below the moving bracket 584 to ensure smooth sliding of the moving bracket 584.

[0081] like Figures 17 to 20 As shown, the retracting device 6 includes a second pulley conveyor line 61 located on the side of the first pulley conveyor line 52, and the safety cone is transported from the first pulley conveyor line 52 to the second pulley conveyor line 61 through the action of the blocking member 53 and the ejection rod 55.

[0082] The second pulley conveyor line 61 has an inclined portion 601 and a straight portion 602 connected to the inclined portion 601, which allows the safety cone to reach ground level from the height of the carriage. The second pulley conveyor line 61 includes a conveyor support 611 pivotally connected to the movable support 584, a conveyor motor 612 fixed to the conveyor support 611, a conveyor belt 616 for conveying the safety cone, and a conveyor chain 613 connected to the conveyor motor 612 and used to drive the conveyor belt. A plurality of stoppers 614 extend vertically from the surface of the conveyor belt 616, and the stoppers 614 are arranged in parallel and at intervals. When the safety cone is pushed onto the second pulley conveyor line 61, the stoppers 614 prevent the cone from sliding downward because the entire conveyor belt 616 is tilted. Since the center of gravity of the safety cone is at its base, the stoppers 614 prevent the cone from tipping over.

[0083] A pair of pressure wheels 603 that can roll along their axes are provided between the inclined portion 601 and the straight portion 602. The pressure wheels 603 press the conveyor belt 616 to ensure that the conveyor belt 616 transitions from the inclined section to the straight section.

[0084] A pair of wheels 60 are mounted on the straight portion 602 of the second pulley conveyor line 61 to ensure that the retractable device 6 follows the vehicle. Through the transition of the straight portion 602, when the conveyor belt 616 continuously rolls and rotates, the safety cone can fall to the ground, ensuring that the safety cone can be placed on the ground according to the predetermined route.

[0085] To ensure that the storage device 6 can be stored in the vehicle body 1, the storage device 6 also includes a tilting assembly 62. The tilting assembly 62 includes a pair of ears 621 mounted on the movable bracket 584, a rotating shaft 622 extending through the ears 621, a connecting ear 623 sleeved on the rotating shaft 622, a first tilting cylinder 624 fixed to the movable bracket 584 and connected to the connecting ear 623, and a second tilting cylinder 625 fixed to the connecting ear 623 and connected to the conveying bracket 611. By activating the first and second tilting cylinders 624 and 625, the conveying bracket 611 can be raised and rotated around the movable bracket 584. The second pulley conveyor line 61 can then be erected and stored in the vehicle body 1.

[0086] The retracting and unloading device 6 also includes a guidance assembly 63 pivotally connected to the straight portion 602 of the second pulley conveyor line 61. The guidance assembly 63 comprises a pair of transverse frames 631, each pivotally connected to the conveyor support 611; a vertical frame 632 extending upward and perpendicular to the transverse frames 631; and a connecting frame 633 connecting the upper ends of the vertical frames 632. The vertical frames 632 and the connecting frame 633 together form an inverted U-shape. The guidance assembly 63 also includes a winding frame 634 movably mounted on the connecting frame 633.

[0087] The connecting frame 633 has a pair of connecting holes 6331 on its surface, aligned in a straight line. The winding frame 634 includes a rotating portion 6341 that receives each connecting hole 6331, a vertical portion 6342 extending perpendicularly from each rotating portion 6341, and a transverse portion 6343 connecting the vertical portions 6342. The connecting holes 6331 are located on the side of the connecting frame 633, facing away from the storage device 2. When the coaching assembly 63 is placed on the ground, the winding frame 634 falls freely. When the safety cone is lowered by the second pulley conveyor line 61, the safety cone can be moved to rotate the connecting frame 633 around the connecting holes 6331. The connecting frame 633 does not interfere with the safety cone, but plays a vital role when the safety cone is retracted.

[0088] A guide frame 635 is installed on the inner side of each transverse frame 631. The rear ends of the two guide frames 635 form a trumpet-shaped structure, which is larger on the outside and smaller on the inside. When the safety cone is retracted, it is used to guide the safety cone so that the safety cone can be smoothly moved between the transverse frames 631.

[0089] The stowage device 6 also includes an auxiliary tilting cylinder 64 for tilting the coaching assembly 63. The cylinder is mounted on the conveying bracket 611, and the output shaft of the auxiliary tilting cylinder 64 is connected to the transverse frame 631. By driving the auxiliary tilting cylinder 64, the coaching assembly 63 can be placed horizontally on the ground or tilted and stored for ultimate storage in the vehicle body 1.

[0090] When safety cones need to be placed, use the above process to place the safety cones.

[0091] When the work is completed and the safety cones need to be retrieved, the automatic safety cone retractor vehicle moves backward to retract them. When the retractor vehicle reverses, the guidance assembly 63 aligns the safety cones and, using the guide frame 635, positions the safety cones between the transverse frames 631. As the vehicle continues to move backward, the free winding frame 634 blocks the upper end of the safety cones, causing them to contact the cones. After the winding frame 634 rotates a certain distance, the connecting frame 633 prevents further rotation. At this point, as the vehicle continues to move backward, the winding frame 634 tilts the safety cones. The base of the safety cone near the vehicle lifts off the ground to the level of the straight portion 602 of the second pulley conveyor line 61. As the vehicle continues to move backward, the winding frame 634 translates backward, disengaging the safety cone from the connecting frame 633 and contacting the second pulley conveyor line 61. Driven by the stopper 614, the safety cone successfully reaches the second pulley conveyor line 61 and is transported upward along the second pulley conveyor line 61.

[0092] When the safety cone reaches the upper end of the inclined portion 601 , by starting the rotary cylinder 56 , the push-back rod 57 initially located on one side rotates rapidly, pushing the safety cone located at the upper end of the inclined portion 601 back to the first pulley conveyor line 52 . The safety cone is then transported to one side through the first pulley conveyor line 52, and then the pushing cylinder 471 is started by the pushing component 472, and the pushing cylinder 471 drives the pushing rod 475 to push the safety cone from the first pulley conveyor line 52 to the direction of the transfer device 4, and the safety cone is knocked down and placed on the placement table 42 by the flip connecting rod 467, and then the transfer motor (not shown) drives the roller 422 to transport the safety cone back, and drives the claw 451 to push the safety cone upward through the lifting component 45 to ensure that the roller 422 is constantly rolling, and ensures that the roller 422 drives the next safety cone to the previous lifting component 45 and is clamped by the claw 451. When the three safety cones are clamped by the three claws 451, the clamping device 3 is started, and the first clamping part 3352 extends into the hollow of the safety cone. The safety cones are then lifted and transported to the fixed rods 231 of the storage device 2. The bases of the safety cones are retained by the fixed rods 231. The drive mechanism 24 rotates the transmission mechanism 23 backward one position. When the next batch of safety cones is clamped to the storage device 2, the drive mechanism 24 rotates the transmission mechanism 23 backward another position. This continues until all the safety cones are clamped and stored.

[0093] If the safety cone on the ground deviates from the retracting device 6 by a certain distance, since the retracting device 6 is installed on the movable bracket 584, the movable bracket 584 can be moved laterally by moving the motor 581 to align the retracting device 6 with the safety cone.

[0094] When all the safety cones are retracted, the retracting device 6 is completely retracted into the vehicle body 1 by driving the turning cylinder 64, the first turning cylinder 624 and the second turning cylinder 625, and the vehicle compartment is locked.

[0095] The automatic safety cone retracting vehicle of the present invention has strong functionality and stable performance. Through the cooperation of various mechanisms, the safety cone can be quickly taken out from the storage device 2 and can also be quickly recovered from the ground.

[0096] Of course, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention and are not used to limit the present invention. As long as they are within the scope of the essential spirit of the present invention, any changes and modifications to the above embodiments will fall within the scope of the claims of the present invention.
