Description

Technical Field

[0001] This invention relates to the technical field of road traffic engineering equipment, and in particular to a traffic cone gradual pitch storage and unstacking device. Background Technology

[0002] Traffic cones are crucial safety facilities used for warning and separating traffic flows in road maintenance, construction, and temporary traffic control scenarios. With the continuous increase in highway mileage and the acceleration of urbanization, the demand for automated deployment and retrieval of traffic cones is becoming increasingly urgent. Traditional manual deployment and retrieval of traffic cones suffers from low efficiency and poor safety, especially in high-traffic scenarios such as highways and urban expressways, where manual operation can no longer meet the requirements for efficient and safe operations. Against this backdrop, developing highly automated and reliable traffic cone storage and stacking devices has become an important direction for improving the mechanization level of road maintenance.

[0003] Currently, the storage and depalletizing technologies for automated traffic cone deployment and retrieval equipment both domestically and internationally mainly follow two technical routes: The first is a conveyor belt storage device with embedded limiting strips. This device uses spaced limiting strips on the conveyor belt surface to hold the traffic cones at a fixed distance, allowing for placement. During deployment, a drive motor moves the conveyor belt, causing the traffic cones to sequentially disengage from the limiting strips. The second is a grid-type device with fixed-distance reciprocating conveying. This device uses a tray with fixed-space grids, and a reciprocating pusher plate pushes the traffic cones to designated positions at fixed distances. For stacking, the operation is reversed. Both types of devices are based on a "storage-transfer-depalletizing / depalletizing" separation design, requiring independent storage, conveying, and depalletizing / depalletizing mechanisms. The operation is completed through the sequential cooperation of multiple devices.

[0004] Existing conveyor belt devices require limit bars to function as both guides and limiters. However, due to the flexible deformation of the belt and stress changes during traffic cone nesting, traffic cones often detach from their fixed positions or become tilted and stuck. This is especially true in dynamic environments such as vehicle speed changes and bumpy rides, where the failure frequency increases significantly. In contrast, during the reciprocating pushing process of grid-type devices, traffic cones need to briefly detach from the push plate control to complete positioning. If the vehicle shakes or there is nesting stress inside the traffic cones at this time, it can easily lead to storage chaos, requiring manual intervention to sort them out, which seriously affects operational efficiency. Furthermore, existing equipment relies on three independent devices for storage, transfer, and depalletizing / unpalletizing, which not only increases the complexity of the mechanical structure and increases costs, but also limits the overall operating speed and results in low efficiency due to the time-consuming connection between the various mechanisms. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a traffic cone gradual pitch storage and depalletizing device, which integrates storage, transportation, and depalletizing functions, simplifies system complexity, reduces costs and control difficulty, and ensures that the traffic cones are effectively limited throughout the storage, transportation, and depalletizing process, effectively preventing storage failures caused by vehicle shaking or stress, and exhibiting good operational stability.

[0006] To address the aforementioned technical issues, this invention provides a traffic cone gradual pitch storage and destacking device. This storage and destacking device is installed on the vehicle body's cargo platform and includes a gradual pitch storage device and a transfer and loading / unloading device. The transfer and loading / unloading device is located at the end of the gradual pitch storage device near the rear of the vehicle and is used to drive the traffic cones in and out of the gradual pitch storage device.

[0007] The gradually changing pitch storage device consists of several gradually changing pitch storage mechanisms arranged side by side. Each of the gradually changing pitch storage mechanisms includes a drive motor, a storage bin frame, and a gradually changing pitch roller. The gradually changing pitch roller is rotatably mounted on the rear cargo platform and located at the bottom of the storage bin frame. The output end of the drive motor is connected to the gradually changing pitch roller to drive the gradually changing pitch roller to rotate.

[0008] The toothed grooves on the gradually pitched roller are adapted to the thickness of the bottom plate edge of the traffic cone. When the traffic cones are stacked on the gradually pitched roller, the bottom plate edge of the traffic cone is inserted into the toothed groove.

[0009] The gradually increasing pitch roller is divided into a storage section and a stacking / unstacking section in the axial direction; the stacking / unstacking section is located at the end of the gradually increasing pitch roller near the transfer and loading / unloading device; the pitch on the stacking / unstacking section is a gradually increasing pitch, which increases in the direction near the transfer and loading / unloading device; the specific structure of the gradually increasing pitch on the stacking / unstacking section is that the tooth groove width remains constant, while the tooth thickness increases in the direction near the transfer and loading / unloading device; the pitch on the storage section is a constant pitch.

[0010] Furthermore, the top of the gradually pitched roller is provided with an auxiliary slider, the bottom of which is threadedly connected to the gradually pitched roller, and the auxiliary slider is slidably connected to the inner wall of the storage rack; the auxiliary slider is provided with a support hole for the insertion of traffic cones, and the cone end of the traffic cone located at the foremost end of the storage rack is inserted into the support hole of the auxiliary slider.

[0011] Furthermore, a number of balls are rotatably embedded in the tooth grooves of the gradually pitched roller.

[0012] Furthermore, the transfer and loading / unloading device includes a transfer platform, a lifting frame, a crossbeam, a front clamping mechanism, and a rear clamping mechanism. The transfer platform is fixed to the carriage platform. Two lifting frames are provided, located at the left and right ends of the transfer platform, respectively. Lifting guide rail mechanisms are provided on the lifting frames to drive the lifting frames to move up and down vertically. The top of the lifting frame is provided with a front and rear sliding guide rail mechanism. The two ends of the crossbeam are connected to the output ends of the corresponding front and rear sliding guide rail mechanisms. The front and rear sliding guide rail mechanisms drive the rear crossbeam to move towards or away from the gradually changing pitch storage device. The front clamping mechanism and the rear clamping mechanism are respectively located on both sides of the crossbeam's length direction. The front clamping mechanism and the rear clamping mechanism cooperate to limit and clamp the traffic cones.

[0013] Furthermore, the cross-sectional shape of the crossbeam is I-shaped, the crossbeam includes an upper plate and a lower plate, the front clamping plate mechanism includes a front fixed plate and a front driving cylinder, the front fixed plate is hinged to the lower plate of the crossbeam near the gradual pitch storage device, the front driving cylinder is hinged to the upper plate of the crossbeam near the gradual pitch storage device, and the piston rod of the front driving cylinder is hinged to the side wall of the front fixed plate to drive the front fixed plate to flip.

[0014] The rear clamping plate mechanism consists of several rear clamping plate assemblies, the number of which is consistent with and corresponds one-to-one with the number of the gradual pitch storage mechanism; each rear clamping plate assembly includes a rear fixed plate and a rear drive cylinder, the rear fixed plate is hinged to the lower plate of the crossbeam on the side away from the gradual pitch storage device; the rear drive cylinder is hinged to the upper plate of the crossbeam on the side away from the gradual pitch storage device, and the piston rod of the rear drive cylinder is hinged to the side wall of the rear fixed plate, driving the rear fixed plate to flip.

[0015] Furthermore, the transfer platform is equipped with a lateral clamping mechanism, which includes a lateral module, a mounting base plate, a transfer clamping plate, and a side clamping cylinder. The mounting base plate is connected to the output end of the lateral module, which drives the mounting base plate to reciprocate laterally. The bottom end of the transfer clamping plate is vertically fixed to the mounting base plate. The transfer platform has a long slot through which the transfer clamping plate passes, and the top end of the transfer clamping plate passes through the long slot to the top wall of the transfer platform. The side clamping cylinder is fixed on the side of the mounting base plate away from the gradual pitch storage device and located on the outside of the transfer platform. The clamping block of the side clamping cylinder cooperates with the transfer clamping plate to clamp and fix the bottom edge of the traffic cone.

[0016] The beneficial effects of this invention are:

[0017] 1. Compared with the problems of belt limit strips and fixed-distance reciprocating conveyor devices in the prior art, such as loss of fixed position and tilting jamming, the present invention, by setting up structures such as gradually pitched rollers and auxiliary blocks, ensures that traffic cones are effectively limited throughout the storage, transfer and unpacking process, effectively avoiding storage failures caused by vehicle shaking or stress, and solving the long-standing reliability problem in the industry.

[0018] 2. Compared with the existing solution where storage, transfer and depalletizing are three separate devices that work in sequence, resulting in low efficiency and high cost, this invention uses a roller design with a gradually varying pitch to achieve integrated storage, transfer and depalletizing functions with only synchronous rotation. No additional auxiliary devices are required. The functions of multiple mechanisms are integrated into a single core component, which significantly simplifies system complexity and reduces cost and control difficulty.

[0019] 3. Unlike traditional gradual pitch conveyors that adjust conveying capacity by widening the tooth grooves or changing the diameter, the gradual pitch roller of this invention adopts a design that keeps the diameter of the tooth grooves unchanged, increases the pitch, and thickens the trailing edge of the helical teeth to ensure that the conveying capacity and limiting capacity do not decrease. At the same time, the roller reduces friction and reduces wear on traffic cones. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] This invention discloses a traffic cone tapered pitch storage and unstacking device.

[0028] Reference Figure 1 and Figure 2 A traffic cone gradual pitch storage and unstacking device is installed on the vehicle body platform 1. The device includes a gradual pitch storage device 2 and a transfer and loading / unloading device 3. The transfer and loading / unloading device 3 is located at the end of the gradual pitch storage device 2 near the rear of the vehicle. The transfer and loading / unloading device 3 is used to drive the traffic cones in and out of the gradual pitch storage device 2.

[0029] Reference Figure 1 and Figure 2 The gradual pitch storage device 2 consists of several gradual pitch storage mechanisms arranged side by side. In this embodiment, there are 5 gradual pitch storage mechanisms. Each gradual pitch storage mechanism includes a drive motor 21, a storage rack 22, a gradual pitch roller 23, and an auxiliary slider 24. The gradual pitch roller 23 is rotatably mounted on the rear cargo platform 1 and is located at the bottom inside the storage rack 22. The output end of the drive motor 21 is connected to the gradual pitch roller 23 to drive the gradual pitch roller 23 to rotate.

[0030] Reference Figure 2 and Figure 3 The toothed grooves on the gradually increasing pitch roller 23 are adapted to the thickness of the bottom plate edge of the traffic cone. When the traffic cones are stacked on the gradually increasing pitch roller 23, the bottom plate edge of the traffic cone is inserted into the toothed grooves. The gradually increasing pitch roller 23 is divided into a storage section 231 and a stacking / unstacking section 232 in the axial direction. The stacking / unstacking section 232 is located at the end of the gradually increasing pitch roller 23 near the transfer and loading / unloading device 3. The pitch on the stacking / unstacking section 232 is a gradually increasing pitch, which increases in the direction near the transfer and loading / unloading device 3. The structure of the gradually increasing pitch on the stacking / unstacking section 232 is that the toothed groove width remains constant, while the tooth thickness increases in the direction near the transfer and loading / unstacking device 3. This ensures that the stacking / unstacking section 232 can carry out the conveying capacity and limiting function of the traffic cones while also being able to stack or unstacking. The pitch on the storage section 231 is a constant pitch, which serves as a front and rear conveying and limiting function for the traffic cones.

[0031] The auxiliary slider 24 is located at the top of the gradually pitched roller 23, and the bottom of the auxiliary slider 24 is threadedly connected to the gradually pitched roller 23. The auxiliary slider 24 is slidably connected to the inner wall of the storage bin rack 22. The auxiliary slider 24 is provided with a support hole for the insertion of traffic cones. The cone end of the traffic cone located at the foremost position on the storage bin rack 22 is inserted into the support hole of the auxiliary slider 24.

[0032] To ensure the effective conveying of traffic cones by the gradually increasing pitch roller 23, several balls 233 are rotatably embedded in the tooth groove of the gradually increasing pitch roller 23 to reduce the friction between the traffic cone and the inner wall of the tooth groove during movement and to reduce wear.

[0033] Reference Figure 4 and Figure 5 The transfer and unloading device includes a transfer platform 31, a lifting frame 32, a crossbeam 33, a front clamping mechanism 34, and a rear clamping mechanism 35. The transfer platform 31 is fixed on the carriage platform 1. There are two lifting frames 32, and the two lifting frames 32 are located at the left and right ends of the transfer platform 31, respectively. A lifting guide rail mechanism 321 is provided on the lifting frame 32. The lifting frame 32 is connected to the transfer platform 31 through the lifting guide rail mechanism 321. The lifting guide rail mechanism 321 can drive the lifting frame 32 to move up and down in the vertical direction.

[0034] The top of the lifting frame 32 is provided with a front and rear sliding guide mechanism 322. The two ends of the crossbeam 33 are connected to the output ends of the corresponding front and rear sliding guide mechanisms 322. The front and rear sliding guide mechanisms 322 can drive the rear crossbeam 33 to move towards or away from the gradual pitch storage device 2. The lifting guide mechanism 321 and the front and rear sliding guide mechanism 322 can adopt ball screw mechanism, gear and rack mechanism, electric push rod or conveyor belt / chain, as long as it can realize lifting or sliding drive. In this embodiment, the lifting guide mechanism 321 adopts electric push rod and the front and rear sliding guide mechanism 322 adopts ball screw mechanism.

[0035] The cross-sectional shape of the crossbeam 33 is I-shaped. The crossbeam 33 includes an upper plate 331 and a lower plate 332 that are parallel to each other. The front clamping mechanism 34 and the rear clamping mechanism 35 are arranged on the crossbeam 33. The front clamping mechanism 34 includes a front fixed plate 341 and a front drive cylinder 342. There is only one front fixed plate 341 and two front drive cylinders 342. The front fixed plate 341 is hinged to the side of the lower plate 332 of the crossbeam 33 near the gradual pitch storage device 2. The front drive cylinders 342 are hinged to the side of the upper plate 331 of the crossbeam 33 near the gradual pitch storage device 2, and the two front drive cylinders 342 are located at both ends of the crossbeam 33. The piston rod of the front drive cylinder 342 is hinged to the side wall of the front fixed plate 341, and then the front drive cylinder 342 can drive the front fixed plate 341 to flip.

[0036] The rear clamping plate mechanism 35 consists of several rear clamping plate assemblies, the number of which corresponds to the number of the gradually changing pitch roller 23 mechanism. Each rear clamping plate assembly includes a rear fixed plate 351 and a rear drive cylinder 352. The rear fixed plate 351 is hinged to the side of the lower plate 332 of the crossbeam 33 away from the gradually changing pitch storage device 2. The rear drive cylinder 352 is hinged to the side of the upper plate 331 of the crossbeam 33 away from the gradually changing pitch storage device 2. The piston rod of the rear drive cylinder 352 is hinged to the side wall of the rear fixed plate 351, and the rear drive cylinder 352 can drive the rear fixed plate 351 to rotate.

[0037] The transfer platform 31 is equipped with a lateral clamping mechanism 36, which is used to move the traffic cone on the transfer platform 31. The lateral clamping mechanism 36 includes a lateral module 361, a mounting base plate 362, a transfer clamping plate 363, and a side clamping cylinder 364. The mounting base plate 362 is connected to the output end of the lateral module 361. The lateral module 361 is used to drive the mounting base plate 362 to reciprocate laterally. The lateral module 361 can be a ball screw mechanism, a gear and rack mechanism, an electric push rod, or a conveyor belt / chain, as long as it can drive the mounting base plate 362 to reciprocate laterally. The bottom end of the transfer clamping plate 363 is vertically fixed on the mounting base plate 362. The transfer platform 31 has a long slot through which the transfer clamping plate 363 passes. The top end of the transfer clamping plate 363 passes through the long slot and exits the top wall of the transfer platform 31. The side clamping cylinder 364 is fixed on the side of the mounting base plate 362 away from the gradual pitch storage device 2 and is located on the outside of the transfer platform 31. The clamping block of the side clamping cylinder 364 cooperates with the transfer clamping plate 363 to clamp and fix the bottom edge of the traffic cone.

[0038] The working principle of a traffic cone gradual pitch storage and destacking device of the present invention is as follows: During the deployment operation, each gradual pitch storage mechanism stores stacked traffic cones. The drive motor 21 drives the gradual pitch roller 23 to rotate, causing the traffic cones and auxiliary sliders 24 to move at a fixed distance towards the transfer and loading / unloading device 3. When the last traffic cone in the stack moves to the destacking section 232, due to the gradual increase in pitch, the last traffic cone gradually detaches from the inside of the previous traffic cone and exits the gradual pitch roller 23 into the transfer and loading / unloading device 3. During this process, 5 rows of gradual pitch... The pitch storage mechanism moves synchronously, and then the five traffic cones approach the transfer platform 31 in a row. At this time, the crossbeam 33 moves to the front end. The rear fixed plate 351 in the rear clamping plate assembly on the crossbeam 33 is in a vertical clamping state under the action of the rear drive cylinder 352. The front fixed plate 341 in the front clamping plate mechanism 34 is in a horizontally open state under the action of the front drive cylinder 342. The traffic cones are released through the gradually changing pitch roller 23 and enter the clamping position between the front fixed plate 341 and the rear fixed plate 351. Subsequently, the front drive cylinder 342 drives the front fixed plate 341 to flip downward to achieve clamping.

[0039] At this point, the five traffic cones are clamped and secured.

[0040] Subsequently, the crossbeam 33 slides backward to the front side of the transfer clamping plate 363 under the action of the front and rear sliding guide rail mechanism 322. Then, the lifting frame 32 rises under the action of the lifting guide rail mechanism 321, so that the bottom end plate of the traffic cone passes over the transfer clamping plate 363. Then, the lifting frame 32 falls down under the action of the lifting guide rail mechanism 321. At this time, the bottom plate of the traffic cone is located behind the transfer clamping plate 363. At this time, the transfer clamping plate 363 and the side clamping cylinder 364 move to the middle position of the traffic cone under the drive of the transverse module 361. Then, the side clamping cylinder 364 is activated, clamping and fixing the bottom plate of the traffic cone between the side clamping cylinder 364 and the transfer clamping plate 363; next, the rear fixing plate 351 in the middle position flips upward and opens, and the traffic cone receiving and placing device picks up the cone from the middle position; after the first traffic cone is taken away, the side clamping cylinder 364 and the transfer clamping plate 363 move to the positions of other adjacent traffic cones in sequence, clamp them, and send them to the middle position for the traffic cone receiving and placing device to pick up and complete the placement, and so on until the placement operation is completed.

[0041] During the recovery operation, the traffic cone deployment and retrieval device located at the rear of the vehicle moves the traffic cones from the ground to the loading / unloading device, with the cone tips facing forward and the bottom plate of the traffic cone positioned between the side clamping cylinder 364 and the transfer clamping plate 363. Subsequently, the side clamping cylinder 364 clamps and fixes the traffic cone, and under the action of the lateral movement module 361, the traffic cone is moved to a position near the side, and is temporarily clamped and fixed by the front fixing plate 341 in conjunction with the rear fixing plate 351. After all 5 traffic cones have been recovered, the lifting frame 32... The traffic cone rises, and then the crossbeam 33 slides forward under the action of the front and rear sliding guide mechanism 322, so that the bottom plate of the traffic cone passes over the transfer clamping plate 363. Then the lifting frame 32 descends, and the crossbeam 33 continues to move forward until the traffic cone is placed at the entrance position of the gradually changing pitch roller 23. At this time, the drive motor 21 drives the gradually changing pitch roller 23 to rotate in the opposite direction, and the traffic cone and auxiliary slider 24 move forward at a fixed distance. As the pitch decreases, the stacking is completed. This cycle is repeated until the recycling operation is completed.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
