Description

Technical Field

[0001] This invention relates to the field of road construction and traffic management equipment technology, specifically to an internally supported, detachable traffic cone automatic deployment and retraction engineering vehicle. Background Technology

[0002] Traffic cones are core warning and guidance facilities in road construction, traffic control, accident emergency response, and maintenance operations. Currently, the on-site deployment and retrieval of traffic cones both domestically and internationally are still mainly done manually. The mainstream operation method is as follows: after the work team drives the engineering vehicle carrying traffic cones to the site, multiple workers work together to manually move the traffic cones one by one to the road surface and place them at intervals within the designated temporary warning area; after the work is completed, the traffic cones are manually collected and carried back to the vehicle. The entire process is highly dependent on manual labor.

[0003] With the surge in road traffic volume and the increasing standardization requirements for road maintenance, the inherent defects of traditional manual operation modes have become increasingly prominent, making them difficult to meet the high-efficiency and safe demands of modern traffic maintenance. To alleviate these problems, automated traffic cone deployment and retrieval equipment has emerged in the industry. For example, the Chinese patent application with publication number "CN116180635A" entitled "A Traffic Cone Deployment and Retrieval Engineering Vehicle" includes a vehicle body, a traffic cone deployment and retrieval space provided on the vehicle body, and an automatic traffic cone deployment and retrieval device for grabbing traffic cones to the deployment and retrieval space. This automatic traffic cone deployment and retrieval device includes a traffic cone grabbing mechanism and a rotary support for horizontally rotating the traffic cone grabbing mechanism. This solution achieves the oblique placement of traffic cones through the rotation of the rotary support, and realizes the grabbing and placement of traffic cones through the cooperation of a telescopic rod, a horizontal transmission mechanism, and a vertical transmission mechanism.

[0004] However, the aforementioned existing technical solutions still have certain limitations: First, traffic cones are usually designed as cone-shaped cylinders with open top and bottom for easy stacking and storage. Multiple traffic cones can be stacked vertically to save space. However, the gripping units in the existing technology (such as vacuum adsorption) can only grip a single, independently placed traffic cone. When multiple traffic cones are stacked vertically, the gripping unit has difficulty effectively separating the top traffic cone from the bottom traffic cone, which can easily lead to gripping failure or the simultaneous lifting of multiple traffic cones, and cannot meet the operational requirements of high-density stacking and storage. Second, the existing technology uses a cone support for storing traffic cones, and each traffic cone needs to be fitted onto the support one by one. The storage density is low and the retrieval and placement path is single, which cannot achieve tight stacking and storage of traffic cones. Third, this solution lacks a mechanism for stabilizing the posture and controlling separation during the gripping process of traffic cones. During vehicle movement or gripping operations, traffic cones are prone to shaking or shifting, affecting gripping accuracy and operational reliability. Therefore, for traffic cones with conical cylindrical bodies that are open at both the top and bottom, this invention provides an automated deployment and retraction vehicle for internally supported, separable traffic cones. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention provides a first and second pipe fitting that are coaxially fitted and movable relative to each other axially. A first gripper that can open radially is provided at the lower end of the first pipe fitting, and a second pressing member that can open radially is provided at the lower end of the second pipe fitting. When gripping vertically stacked traffic cones, the first pipe fitting extends into the upper opening of the uppermost traffic cone. The second pipe fitting moves downward, driving the first gripper to open radially to internally tighten the traffic cone. Simultaneously, the second pressing member opens radially and presses against the upper surface of the adjacent lower traffic cone. By lifting the first pipe fitting, the uppermost traffic cone can be effectively separated from the stacked traffic cones below. This solves the problem of separating and gripping stacked traffic cones with openings at both ends, achieving reliable single-grip gripping under high-density stacked storage.

[0023] 2. The present invention uses a positioning cover sleeve that is vertically slidably sleeved on the outside of the first pipe fitting, and sets a compression spring between the positioning cover sleeve and the transverse plate. Before gripping, the positioning cover sleeve first contacts and covers the traffic cone to stabilize the posture and center the traffic cone. Then, in conjunction with the pressure sensor to detect the contact pressure, the descent stroke of the lifting mechanism is precisely controlled, which avoids the traffic cone shaking or deviating during the gripping process, and greatly improves the gripping accuracy and operational reliability.

[0024] 3. This invention controls the up-and-down movement of the top claw plug by using a lifting linkage plate. The top claw stake at the lower end of the top claw plug cooperates with the supporting claw on the lower top claw, which can actively control the radial contraction and opening of the lower top claw. This avoids the potential delay or failure risk that may exist if the passive opening is achieved solely by relying on the counterweight column under gravity, thus improving the reliability of the separation action and the accuracy of the control.

[0025] 4. This invention utilizes the coordinated operation of a lifting mechanism, a lateral movement mechanism, a gripping mechanism, and a conveying device consisting of a central storage conveyor belt and a take-up and release conveyor belt to achieve automated handling and transfer from the stacked storage area to the delivery release area. The entire operation process—gripping-separation-lateral movement-placement-transfer—forms a complete automated take-up and release operation chain, reducing reliance on manual labor and improving the safety and efficiency of road construction operations.

[0047] For details, please refer to [link / reference]. Figure 8A positioning cover 12 is vertically slidably sleeved on the outer side of the first pipe fitting 501. The positioning cover 12 is a cylindrical structure with a closed upper end and an open lower end. The outer sleeve 505 and the lifting rod 9 slide through the upper end face of the positioning cover 12. The upper end face of the positioning cover 12 and the lower end face of the transverse plate 6 are fixedly connected by a set of compression springs 13. The set of compression springs 13 consists of two springs, which are respectively sleeved on the outer side of the lifting rod 9 to provide a downward elastic preload for the positioning cover 12. A pressure sensor 14 is fixedly installed on the outer wall of the first pipe fitting 501. A pressure ring 15 is vertically slidably sleeved on the outer wall of the first pipe fitting 501. The lower end face of the pressure ring 15 coincides with the lower end face of the first pipe fitting 501. A buffer spring 16 is sleeved on the outer side of the first pipe fitting 501. A pressure collar 17 is fixedly installed on the lower detection section of the pressure sensor 14. The two ends of the buffer spring 16 are respectively fixedly connected to the upper end face of the pressure cylinder ring 15 and the lower end face of the pressure collar 17. The pressure sensor 14 is used to detect the contact pressure between the first pipe fitting 501 and the traffic cone to control the descent stroke of the lifting mechanism 4.

[0048] Working Principle: After the workers drive the engineering vehicle to the destination, they first perform the grabbing and separating of traffic cones: Positioning and Pre-compression: The lifting mechanism 4 is activated to drive the grabbing mechanism 5 to descend. First, the positioning cover 12, under the pre-tightening force of the compression spring 13, contacts and covers the top of the uppermost traffic cone, performing initial positioning and posture stabilization of the traffic cone. The pressure sensor 14 detects the contact pressure. When the pressure reaches the preset value, the lifting mechanism 4 is controlled to stop descending, ensuring that the lower end of the first pipe 501 has reached a suitable depth into the upper opening of the traffic cone. Grabbing: The separation servo motor on the lifting linkage plate 7 is activated, driving the lifting linkage plate 7 to move downward relative to the transverse plate 6 through the meshing of the gear and the lifting rack 602. Since the lifting linkage plate 7 is fixedly connected to the first pipe 501 through the lifting rod 9 and the lifting plate 8, the first pipe 501 is moved downward. At this time, the second pipe 502 is fixed to the transverse plate 6 and remains stationary through the outer sleeve 505. The downward movement of the first pipe fitting 501 causes its lower inner support claw 503a to disengage from the restraint of the lower end of the second pipe fitting 502. The inner support claw 503a opens radially outward, tightening the inner wall of the uppermost traffic cone from the inside. Downward separation: Immediately afterwards, the lifting servo motor on the lifting linkage plate 506 drives the lifting linkage plate 506 to move downward relative to the transverse plate 6 via the lifting screw 10. The lifting linkage plate 506 pushes the top claw plug 507 down inside the second pipe fitting 502 via the lifting rod 507a. The top claw post 507b at the lower end of the top claw plug 507 pushes down to open the supporting claw on the lower top claw 504a, causing the lower top claw 504a to rotate downward around the axis and open. The opened lower top claw 504a presses against the upper end surface of the adjacent lower (i.e., the second) traffic cone. Lifting separation: The separation servo motor reverses its direction, and the lifting linkage plate 7 moves upward, driving the first pipe fitting 501 upward via the lifting rod 9 and the lifting plate 8. Since the inner support claw 503a has tightened the uppermost traffic cone, the traffic cone is pulled upwards. At this time, the second pipe 502 and its lower end claw 504a remain stationary and firmly abut against the lower traffic cone. Under the combined action of the upward pulling force and the downward reaction force, the uppermost traffic cone separates cleanly from the stack below.

[0049] Conveying and Placing Stage: Lateral Movement: The gripping mechanism 5, carrying the separated traffic cones, moves horizontally from above the storage frame 2 to above the central storage conveyor belt 302, driven by the lateral servo motor of the lifting mechanism 4 and guided by the lateral rack 405 and lateral slide bar 406. Releasing the Traffic Cone: The lifting linkage plate 7 and the lifting plug linkage plate 506 of the gripping mechanism 5 move in opposite directions, causing the inner support claw 503a to retract inward and the lower top claw 504a to retract upward, releasing the constraint on the traffic cone. The traffic cone is then smoothly placed on the central storage conveyor belt 302. Conveying Output: The central storage conveyor belt 302 starts, conveying the traffic cone towards the rear of the vehicle. The traffic cone is finally transferred to the take-up and release conveyor belt 301, which then transports it to a preset position on the road surface, completing the placement. The recycling operation proceeds in reverse order.
