Description

Technical Field

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

[0002] Traffic cones are critical safety features used for warning and separating traffic in road maintenance, construction, and temporary traffic control scenarios. With the continued growth of highway mileage and the acceleration of urbanization, the need for automated deployment and retraction 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. Manual operation can no longer meet the requirements for efficient and safe operations. Against this backdrop, the development of highly automated and reliable traffic cone storage and destacking devices has become an important step in improving the mechanization of road maintenance.

[0003] Currently, the storage and depalletizing technologies for automatic traffic cone retraction equipment at home and abroad mainly follow two technical routes: the first is a conveyor belt storage device with embedded limit bars. By setting interval limit bars on the surface of the conveyor belt, the bottom of the traffic cone is stuck between the limit bars to achieve fixed-distance transportation. When placing, the conveyor belt is driven by a drive motor to move the traffic cones so that they are sequentially released from the limit bars. The second is a grid-type device with fixed-distance reciprocating transportation. It uses a pallet with fixed-spacing grids. The traffic cones are pushed to the specified position one by one by a reciprocating push plate. When palletizing, the reverse operation is performed to achieve stacking. Both types of devices are based on the design concept of "storage-transfer-depalletizing / stacking" separation. They require independent storage mechanisms, conveying mechanisms, and depalletizing / stacking mechanisms. The operation is completed through the serial collaboration of multiple sets of devices.

[0004] The existing limit strips of conveyor belt devices need to take into account both guiding and limiting functions, but are limited by the flexible deformation of the belt and the stress changes when the traffic cones are nested. Traffic cones often become disengaged from their fixed positions or tilted and stuck, especially in dynamic environments such as vehicle speed changes and bumps. The frequency of failures increases significantly. During the reciprocating pushing process of the grid-type device, the traffic cones need to be temporarily disengaged from the push plate control to complete positioning. If the vehicle shakes at this time or there is nesting stress inside the traffic cones, it is very easy to cause chaos in the warehouse, and manual intervention is required for subsequent sorting, which seriously affects work efficiency. In addition, the existing equipment relies on three independent devices for storage, transportation, and depalletizing. This not only increases the complexity of the mechanical structure and high costs, but also limits the overall operation speed due to the time-consuming connection between the various mechanisms, resulting in relatively low efficiency.

These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0027] The present invention discloses a traffic cone variable pitch storage and palletizing / depalletizing device.

[0028] Refer to Figure 1 and Figure 2 , a traffic cone variable pitch storage and palletizing / depalletizing device, which is installed on the carriage platform 1 of the vehicle body, and includes a variable pitch storage device 2 and a transfer in / out bin device 3; the transfer in / out bin device 3 is arranged at one end of the variable pitch storage device 2 close to the rear of the vehicle; the transfer in / out bin device 3 is used to drive traffic cones in and out of the variable pitch storage device 2.

[0029] Refer to Figure 1 and Figure 2 , the variable pitch storage device 2 is composed of a number of variable pitch storage mechanisms arranged side by side. In this embodiment, there are 5 variable pitch storage mechanisms. Each variable pitch storage mechanism includes a driving motor 21, a storage bin rack 22, a variable pitch roller 23 and an auxiliary slider 24. The variable pitch roller 23 is rotatably installed on the rear carriage platform 1 and is located at the bottom inside the storage bin rack 22. The output end of the driving motor 21 is connected to the variable pitch roller 23 to drive the variable pitch roller 23 to rotate.

[0030] Refer to Figure 2 and Figure 3 , the tooth grooves on the variable pitch roller 23 are adapted to the thickness of the bottom plate of the traffic cone. When the traffic cones are stacked on the variable pitch roller 23, the bottom plate edges of the traffic cones are inserted into the tooth grooves. The variable pitch roller 23 is axially divided into a storage section 231 and a palletizing / depalletizing section 232. The palletizing / depalletizing section 232 is located at one end of the variable pitch roller 23 close to the transfer in / out bin device 3; the pitch on the palletizing / depalletizing section 232 is a variable pitch, and the pitch increases in the direction close to the transfer in / out bin device 3. The structure of the variable pitch on the palletizing / depalletizing section 232 is that the width of the tooth groove remains unchanged, and the tooth thickness increases in the direction close to the transfer in / out bin device 3, so as to ensure the conveying ability and limiting function of the palletizing / depalletizing section 232 for traffic cones while being able to perform stacking or depalletizing; the pitch on the storage section 231 is an equal pitch, which plays a role in limiting the front and back conveying of traffic cones.

[0031] The auxiliary slider 24 is located at the top of the variable pitch roller 23. The bottom of the auxiliary slider 24 is threadedly connected to the variable pitch roller 23, and the auxiliary slider 24 is slidably connected to the inner wall of the storage bin rack 22; a support hole for inserting the traffic cone is provided on the auxiliary slider 24, and the cone end of the traffic cone at the frontmost end on the storage bin rack 22 is inserted into the support hole of the auxiliary slider 24.

[0032] In order to ensure the conveying effect of the variable pitch roller 23 on the traffic cones, a plurality of balls 233 are rotatably embedded in the tooth grooves of the variable pitch roller 23 to reduce the friction between the traffic cones and the inner wall of the tooth groove during movement and reduce wear.

[0033] Reference Figure 4 and Figure 5 The transfer and out-of-warehouse device includes a transfer platform 31, a lifting frame 32, a crossbeam 33, a front splint mechanism 34, and a rear splint mechanism 35; the transfer platform 31 is fixed on the carriage platform 1, and there are two lifting frames 32, and the two lifting frames 32 are respectively located at the left and right ends of the transfer platform 31. A lifting guide rail mechanism 321 is set on the lifting frame 32, and 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] A front-to-rear sliding guide rail mechanism 322 is provided at the top of the lifting frame 32. The ends of the crossbeam 33 are connected to the corresponding output ends of the front-to-rear sliding guide rail mechanism 322. The front-to-rear sliding guide rail mechanism 322 can drive the rear crossbeam 33 toward or away from the variable-pitch storage device 2. The lifting guide rail mechanism 321 and the front-to-rear sliding guide rail mechanism 322 can utilize a ball screw mechanism, a rack and pinion mechanism, an electric push rod, or a conveyor belt / chain, as long as they can achieve lifting or sliding drive. In this embodiment, the lifting guide rail mechanism 321 utilizes an electric push rod, and the front-to-rear sliding guide rail mechanism 322 utilizes a ball screw mechanism.

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

[0036] The rear clamping plate mechanism 35 is composed of a number of rear clamping plate components, and the number of rear clamping plate components is the same as and corresponds one by one to the number of the variable pitch roller mechanisms 23. The rear clamping plate component includes a rear fixing plate 351 and a rear driving cylinder 352. The rear fixing plate 351 is hinged to the lower plate body 332 of the cross beam 33 on the side away from the variable pitch storage device 2; the rear driving cylinder 352 is hingedly installed on the upper plate body 331 of the cross beam 33 on the side away from the variable pitch storage device 2. The piston rod of the rear driving cylinder 352 is hinged to the side wall of the rear fixing plate 351. Subsequently, the rear driving cylinder 352 can drive the rear fixing plate 351 to flip.

[0037] A transverse movement and clamping mechanism 36 is arranged in the transfer platform 31. The transverse movement and clamping mechanism 36 is used to drive the traffic cone to move on the transfer platform 31. The transverse movement and clamping mechanism 36 includes a transverse movement module 361, a mounting bottom plate 362, a transfer clamping plate 363 and a side posture clamping cylinder 364. The mounting bottom plate 362 is connected to the output end of the transverse movement module 361. The transverse movement module 361 is used to drive the mounting bottom plate 362 to reciprocate horizontally. The transverse movement module 361 can adopt 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 bottom plate 362 to reciprocate horizontally. The bottom end of the transfer clamping plate 363 is vertically fixed on the mounting bottom plate 362. A long slot for the transfer clamping plate 363 to pass through is formed on the transfer platform 31. The top end of the transfer clamping plate 363 passes through the top wall of the transfer platform 31 through the long slot. The side posture clamping cylinder 364 is fixed on the side of the mounting bottom plate 362 away from the variable pitch storage device 2 and is located outside the transfer platform 31. The clamping block of the side posture clamping cylinder 364 cooperates with the transfer clamping plate 363 to clamp and fix the bottom plate edge of the traffic cone.

[0038] The working principle of a traffic cone variable pitch storage and palletizing / depalletizing device of the present invention: During the placement operation, each variable pitch storage mechanism stores stacked traffic cones. The driving motor 21 drives the variable pitch roller 23 to rotate, driving the traffic cone and the auxiliary slider 24 to move a fixed distance towards the transfer in / out bin device 3. When the traffic cone at the very end of the stacked traffic cones moves to the palletizing / depalletizing section 232, due to the gradually increasing pitch, the traffic cone at the very end gradually disengages from the inside of the previous traffic cone and disengages from the variable pitch roller 23 and enters the transfer in / out bin device 3. During this process, the 5 variable pitch storage mechanisms move synchronously. Subsequently, 5 traffic cones approach the transfer platform 31 in a row. At this time, the cross beam 33 moves to the front end. The rear fixing plate 351 in the rear clamping plate component on the cross beam 33 is in a vertical clamping state under the action of the rear driving cylinder 352. The front fixing plate 341 in the front clamping plate mechanism 34 is in a horizontal open state under the action of the front driving cylinder 342. After the traffic cone is disengaged through the variable pitch roller 23, it enters the clamping position between the front fixing plate 341 and the rear fixing plate 351. Subsequently, the front driving cylinder 342 drives the front fixing plate 341 to flip downwards to achieve clamping.

[0039] At this time, the five traffic cones are clamped and fixed;

[0040] Subsequently, the cross beam 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 crosses the transfer clamping plate 363. Then, the lifting frame 32 descends under the action of the lifting guide rail mechanism 321. At this time, the bottom plate of the traffic cone is located at the rear side of the transfer clamping plate 363. At this time, the transfer clamping plate 363 and the side posture clamping cylinder 364 move to the position of the middle traffic cone driven by the transverse movement module 361. Then, the side posture clamping cylinder 364 is activated to clamp and fix the bottom plate edge of the traffic cone between the side posture clamping cylinder 364 and the transfer clamping plate 363. Then, the rear fixing plate 351 at the middle position is turned upward and opened, and the traffic cone retracting and deploying device performs the operation of taking and deploying cones from the middle position. After the first traffic cone is taken away, the side posture 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 retracting and deploying device to take and complete the deployment. This process is repeated until the deployment operation is completed.

[0041] During the recycling operation, the traffic cone retracting and deploying device at the rear side of the vehicle transports the traffic cones from the ground to the loading and unloading device, making the cone tip face forward and the bottom plate of the traffic cone placed between the side posture clamping cylinder 364 and the transfer clamping plate 363. Subsequently, the side posture clamping cylinder 364 clamps and fixes the traffic cone, and moves the traffic cone to the side position under the action of the transverse movement module 361, and performs temporary clamping and fixing through the cooperation of the front fixing plate 341 and the rear fixing plate 351. When the recycling of the five traffic cones is completed, the lifting frame 32 rises. Subsequently, the cross beam 33 slides forward under the action of the front and rear sliding guide rail mechanism 322, so that the bottom plate of the traffic cone crosses the transfer clamping plate 363. Then, the lifting frame 32 descends, and the cross beam 33 continues to move forward until the traffic cone is placed at the entrance position of the variable pitch roller 23. At this time, the driving motor 21 drives the variable pitch roller 23 to rotate reversely, and the traffic cone and the auxiliary slider 24 move forward at a fixed distance. As the pitch becomes smaller, the stacking is completed. This process is repeated until the recycling operation is completed.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
