Description

TECHNICAL FIELD

[0001] The present application belongs to the field of road maintenance industry professional engineering vehicles, and particularly relates to a traffic cone barrel automatic receiving and sending mechanism and a receiving and sending method. BACKGROUND

[0002] Up to now, the total mileage of expressways in China reaches 190,700 kilometers, ranking first in the world. At the same time, the expressway maintenance task is increasingly heavy, and it is urgent to automate and efficiency the maintenance work while ensuring the safety of personnel and vehicles. Under this background, the expressway maintenance machinery in China is booming.

[0003] During maintenance work, road cones must be placed along the outer edge of the work area to guide passing vehicles, divide the driving section and the work section, and ensure work safety and form safety. In recent years, various semi-automatic and automatic cone barrel receiving and sending technologies have been proposed to achieve this goal.

[0004] For example, the Chinese patent document (application number: CN202010807887.0) proposes a full-automatic cone barrel receiving and sending technology. This technology is separated for receiving and sending, transversely adjustable, inverted storage, and can receive and send traffic cones in a forward driving manner, which can meet the curve section receiving and sending operation. The receiving and sending operation can be performed simultaneously, and the traffic cone can be transferred across the lane.

[0005] For example, the Chinese patent document (application number: CN202010021510.2) provides a lateral full-mechanical type cone barrel automatic receiving and sending device. The distribution device is installed on both sides of the vehicle body, and uses two side plates, guide plates and guide strips to right the cone barrel.

[0006] However, the above-mentioned inventions using automatic mechanical structures can realize the automatic distribution and recovery of the cone barrel. In order to improve the work efficiency, the receiving and sending separation mode is adopted, which brings the problem of low utilization rate of carrying space, especially the problem of internal negative pressure suction caused by long-term accumulation of the cone barrel and the problem of lane occupation caused by lateral installation, which seriously affects the success rate of cone barrel distribution and the driving safety of the passing lane. Therefore, the engineering application of the traffic cone barrel automatic distribution equipment is seriously restricted. SUMMARY

[0007] The present application proposes a traffic cone barrel automatic distribution mechanism and method to solve the above-mentioned problems in the prior art. The mechanism adopts a receiving and sending integrated carrying platform tail configuration, which greatly solves the problems of low utilization rate of carrying platform space and lane occupation while ensuring the efficiency of cone barrel receiving and sending. At the same time, a special stacking mechanism is designed to solve the problem of negative pressure suction of the cone barrel. Its structure is exquisite, the action is simple, the labor intensity of the construction personnel is reduced while the work efficiency is ensured, and the safety of personnel and lane is improved.

[0009] Further, the distribution support lifting slide rail is further provided; the distribution support lifting slide rail is fixed on the distribution truss; and the distribution support is driven by the distribution support lifting slide rail to lift in the vertical direction.

[0010] Further, the distribution cylinder and the push-pull mechanism are further provided; the distribution cylinder and the push-pull mechanism are respectively fixed on the upper part of the distribution truss, and the distribution cylinder and the push-pull mechanism are at the same height as the lower supporting plate.

[0011] Further, the frame bottom is provided with universal wheels.

[0012] The method for placing the cone barrel by the traffic cone barrel automatic receiving and sending mechanism comprises the following steps. Step one, fixing the traffic cone barrel automatic receiving and sending mechanism on a movable carrier, and initially placing the cone barrel stack on the lower supporting plate of the distribution stacking mechanism; Step two, inserting the upper shovel plate of the distribution stacking mechanism into the gap between the bottommost cone barrel and the second-to-last cone barrel of the cone barrel stack, synchronously retracting the lower supporting plate, dropping the bottommost cone barrel, receiving the bottommost cone barrel by the conical disc, then driving the swing direction frame to move downward by the swing direction frame lifting slide rail until the swing direction frame is close to the ground; Step three, turning the conical disc by 90° under the action of the turnover mechanism, and making the cone barrel fall off the conical disc and be placed horizontally on the ground, and then moving the carrier forward, and righting the cone barrel by the front beam of the frame pushing the single-side edge of the bottom of the cone barrel, thereby realizing the placement of one cone barrel; Step four, continuously moving the carrier forward, repeating the above process by the traffic cone barrel automatic receiving and sending mechanism, and planning the placement path of the cone barrel by the swing direction rod, thereby completing the process of placing the cone barrels one by one.

[0013] The method for recycling the cone barrel by the traffic cone barrel automatic receiving and sending mechanism comprises the following steps: Step one, the traffic cone barrel automatic receiving and sending mechanism is fixed on the movable carrier, the swing-to-pole is matched with the camera to identify the position of the cone barrel, and the cone barrel is collected to the front side of the front beam of the frame by adjusting the opening and closing angle of the swing-to-pole; Step two, the carrier continues to travel towards the cone barrel direction, the front beam of the frame pushes the cone barrel on the ground, the cone-shaped disc is sleeved into the bottom of the cone barrel, that is, the cone-shaped disc supports the cone barrel, and the cone-shaped disc rotates upward by 90°, that is, the cone barrel is righted; Step three, the swing-to-pole lifting slide rail drives the swing-to-pole to move upward, the swing-to-pole moves the cone barrel to the stacking mechanism, and the lower supporting plate of the stacking mechanism is inserted into the bottom of the cone barrel to support the cone barrel; Step four, the above process is repeated, and the cone barrels are stacked on the lower supporting plate of the stacking mechanism, that is, the recycling process of the cone barrels is realized.

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention. Example

[0025] like Figure 1 As shown, an automatic traffic cone dispensing and receiving mechanism includes a dispensing truss 1, a swing frame lifting slide rail 2, a stacking mechanism 3, a dispensing bracket lifting slide rail 4, a dispensing bracket 5, a swing frame 6, a push-pull mechanism 7, and a dispensing roller 8.

[0026] The sway frame lifting slide rail 2 and the distribution bracket lifting slide rail 4 are respectively fixed on the distribution truss 1. The sway frame lifting slide rail 2 is used to realize the lifting and lowering of the sway frame 6, and the distribution bracket lifting slide rail 4 is used to realize the lifting and lowering of the distribution bracket 5.

[0027] The distributing roller 8 and the stacking mechanism 3 are fixed to the distributing truss 1, as follows: Figure 2 As shown, the stacking mechanism 3 is used to split the cone barrels one by one. It includes a power gear 3-1, a first driven wheel 3-2, a second driven wheel 3-3, an upper shovel plate 3-4, and a lower support plate 3-5. The power gear 3-1 is driven by an independent power unit (omitted in the figure). The power gear 3-1 distributes power proportionally to the first driven wheel 3-2 and the second driven wheel 3-3. The upper shovel plate 3-4 and the lower support plate 3-5 are respectively connected to independent linear actuators (e.g., screw actuators). The first driven wheel 3-2 and the second driven wheel 3-3 drive the linear actuators of the upper shovel plate 3-4 and the lower support plate 3-5 respectively, so that the upper shovel plate 3-4 and the lower support plate 3-5 form an alternating extension and retraction motion pattern in the horizontal direction.

[0028] The lower support plate 3-5 and the distributing roller 8 are at the same horizontal position, ensuring that when the lower support plate 3-5 extends, the cone stack can move horizontally from the distributing roller 8 to the lower support plate 3-5; when the upper shovel plate 3-4 extends and inserts into the bottom of the second to last cone of the cone stack, the lower support plate 3-5 retracts, and the bottom cone of the cone stack falls vertically due to its gravity, thereby achieving the separation of the cones.

[0029] like Figure 3 As shown, the distribution bracket 5 includes a frame 5-1, casters 5-2, and a sway bar 5-3. The frame 5-1 includes a connecting beam connecting the slider of the distribution bracket lifting slide rail 4 and a front beam parallel to the sway bar 6. The sway bar 6 moves within the frame 5-1. Casters 5-2 are provided at the bottom of the frame 5-1, and the sway bar 5-3 for adjusting the placement path of the cone is provided at the front of the frame 5-1. The sway bar 5-3 is hinged to both sides of the front of the frame 5-1 and driven by an independent motor. A camera is placed near the sway bar 5-3.

[0030] like Figure 4 As shown, the slewing frame 6 includes a slide rail connecting plate 6-1, a conical disk 6-2, a tilting mechanism, and a slewing truss 6-5. The slewing truss 6-5 is connected to the slider of the slewing frame lifting slide rail 2 through the slide rail connecting plate 6-1. The slewing truss 6-5 is movably connected to the conical disk 6-2 and is driven by the tilting mechanism to rotate the conical disk 6-2 within a 90° range. The tilting mechanism includes a first gear set 6-3, a second gear set 6-4, and a power device for driving the gear sets to rotate.

[0031] like Figure 5 As shown, the push-pull mechanism 7 includes a push-pull electromagnet 7-1, a push rod base 7-2, a return spring 7-3, a movable tongue 7-4, and an electric push rod 7-5. The fixed end of the push-pull mechanism 7 is fixed to the distribution truss 1. The front end of the electric push rod 7-5 of the push-pull mechanism 7 is connected to the push rod base 7-2. The push rod base 7-2 is equipped with the push-pull electromagnet 7-1, the return spring 7-3, and the movable tongue 7-4. The lower part of the movable tongue 7-4 is connected to the return spring 7-3. The extension and retraction of the return spring 7-3 are controlled by the push-pull electromagnet 7-1, thereby realizing the extension and retraction of the movable tongue 7-4 in the vertical direction. The push-pull mechanism 7 is at the same height as the distribution roller 8, so that the push-pull action of the push-pull mechanism 7 can realize the pulling of the cone barrel from the distribution roller 8 to the lower support plate 3-5 of the stacking mechanism 3 or the pushing of the cone barrel from the lower support plate 3-5 of the stacking mechanism 3 to the distribution roller 8.

[0032] Automatic dispatching and receiving method for traffic cones: I. Steps for deploying cones The automatic traffic cone dispensing and receiving mechanism is fixed on a moving vehicle. The push-pull electromagnet 7-1 of the push-pull mechanism 7 is energized and engaged, the movable tongue 7-4 retracts, and the electric push rod 7-5 extends until the movable tongue 7-4 reaches the bottom of the cone stack. The push-pull electromagnet 7-1 is de-energized, and the movable tongue 7-4 is reset under the action of the return spring 7-3. At this time, the movable tongue 7-4 hangs on the bottom of the cone stack, the electric push rod 7-5 retracts, and the cone stack is pulled from the dispensing roller 8 to the lower support plate 3-5, that is, the cone stack reaches the initial position. The upper shovel plate 3-4 of the stacking mechanism 3 is inserted into the gap between the bottom cone and the second to last cone of the stack. The lower support plate 3-5 retracts simultaneously, the bottom cone falls down and is supported by the conical plate 6-2. Then the swing frame lifting slide rail 2 drives the swing frame 6 to move down until it is close to the ground. The cone disc 6-2 completes a 90° turn under the action of the flipping mechanism. The cone falls off the cone disc 6-2 and is placed horizontally on the ground. As the vehicle moves forward, the front beam of the frame 5-1 pushes the single edge of the bottom of the cone to straighten the cone, thus realizing the placement of a cone. The vehicle continues to move forward, and the automatic traffic cone dispatching and receiving mechanism repeats the above process. By using the swing lever 5-3 to plan the cone placement path, the process of placing the cones one by one is completed.

[0033] Cone recycling steps The automatic traffic cone dispatching and receiving mechanism is fixed on a moving vehicle. The sway bar 5-3, in conjunction with the camera, identifies the position of the cones. By adjusting the opening and closing angle of the sway bar 5-3, the cones are collected to the front side of the front beam of the frame 5-1. The vehicle continues to move toward the cone. The front beam of frame 5-1 pushes the cone over on the ground. The conical disc 6-2 fits into the bottom of the cone, thus supporting the cone. The conical disc 6-2 rotates upward 90°, thus righting the cone. The lifting slide rail 2 of the swing frame drives the swing frame 6 to move upward. The swing frame 6 moves the cone to the stacking mechanism 3. The lower support plate 3-5 of the stacking mechanism 3 is inserted into the bottom of the cone to support the cone. Repeat the above process to stack the cone-shaped drums on the lower support plate 3-5 of the stacking mechanism 3, thus realizing the process of recycling the cone-shaped drums one by one.

[0034] When the automatic traffic cone dispensing and receiving mechanism is no longer in use, the dispensing bracket 5 can be lifted by lifting the slide rail 4 of the dispensing bracket.

[0035] like Figure 6 As shown, when the distribution support 5 moves along direction A, the front beam of frame 5-1 pushes one side of the bottom edge of the cone, causing the cone to straighten along direction B; when the distribution support 5 moves along direction a, the front beam of frame 5-1 pushes the cone over, that is, the cone falls down along direction b.

[0036] The swing arm 6 can swing in both the C and c directions.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
