Description

Technical Field

[0002] Expressways are an objective reflection of the transportation needs of modern economic development. Expressway construction not only reflects the level of transportation development in a country, but also reflects the overall level of economic development. With the rapid development of my country's economic construction, the number of motor vehicles in my country has continued to grow rapidly. The huge fleet of motor vehicles not only brings huge challenges to expressway maintenance, but also brings many problems to expressway traffic safety.

[0003] In order to ensure the safety of highways, necessary maintenance must be carried out on them. When carrying out highway maintenance, it is necessary to close traffic control on some sections of the road, and place traffic cones and other guide signs outside the work area to guide vehicles. At present, in highway maintenance operations in my country, the placement and collection of traffic cones are mainly manual and fully automatic. Among them, in manual operation, 2 to 3 operators are required to place and collect traffic cones on the road or along the road at the rear of the engineering vehicle. This operation method is not only slow, but more seriously, the operators are always exposed to dangerous traffic environments, which seriously threatens the personal safety of the operators; fully automatic operation equipment can ensure the personal safety of operators during the placement and collection of traffic cones, but it has strict requirements on the personal qualities of operators.

[0043] The deployment process of the automatic traffic cone retracting and releasing device is as follows: after the transport vehicle 1 runs to the road where the traffic cones are required to be placed for guiding traffic, the hydraulic strut 425 begins to extend, and at the same time drives the left lower ramp plate 410 and the right lower ramp plate 411 of the retracting and releasing assembly 4 and the gantry assembly 5 to rotate downward until the omnidirectional wheel 423 contacts the road surface, and then the electric roller f drives the manipulator assembly 506 on the fixed sleeve 505 to rotate to a horizontal direction.

[0044] The process of placing traffic cones is as follows: after the automatic traffic cone retracting and releasing device is unfolded, the traffic cones are placed diagonally on the left side of the transport vehicle 1, and the electric roller a202 at the rear of the transport vehicle 1 rotates to the left; at the same time, the motor 310 starts, driving the toothed belt 305 to rotate to the left, the toothed belt 305 drives the moving slide 302 to move to the left, and the moving slide 302 drives the retracting and releasing assembly 4 to move to the left end of the rear of the transport vehicle 1; at this time, the electric roller c403, the electric roller d412, and the electric roller e416 are started at the same time, driving the conveyor belt a405, the conveyor belt b414, and the conveyor belt c418 to rotate downward respectively; then the transport vehicle 1 moves forward, and the operator stands behind the safety barrier 7 to move the traffic cones stored in the compartment of the transport vehicle 1. The traffic cone is placed on the electric roller a202, and the electric roller a202 transports the traffic cone to the left end of the rear of the transport vehicle 1. At this time, the electric roller b203 corresponding to the side of the traffic cone is started, driving the cone pusher belt 204 to rotate in the direction of the retractable assembly 4. The traffic cone runs to the conveyor belt a405 of the retractable assembly 4 under the action of the surface block a of the cone pusher belt 204. At the same time, according to the diagonal placement requirements of the traffic cone, the motor 310 is restarted to drive the toothed belt 305 to rotate, the toothed belt 305 drives the moving slide 302 to run, and the moving slide 302 drives the retractable assembly 4 to run to the corresponding position. The traffic cone is placed on the road surface driven by the conveyor belt a405, the conveyor belt b414, and the conveyor belt c418. If the traffic cone is placed diagonally on the right side of the transport vehicle 1, the control method of the electric roller a202 and the motor 310 is reversed. By combining the speed of the transport vehicle 1 and controlling the start-up and operation time of the transmission assembly 2, the moving assembly 3, and the retractable assembly 4, the placement of traffic cones with different spacings and different line types can be completed.

[0045] The process of collecting traffic cones is as follows: start the electric roller a202 at the rear of the transport vehicle 1 to rotate toward the direction where the operator is located in the transport vehicle 1, and at the same time start the electric roller c403, electric roller d412, and electric roller e416 of the retracting assembly 4, respectively driving the conveyor belt a405, conveyor belt b414, and conveyor belt c418 to rotate upwards, then the electric roller f drives the manipulator assembly 506 on the fixed sleeve 505 to rotate to the vertical direction, then the transport vehicle 1 runs backward, and at the same time start the motor 310 to drive the toothed belt 305 to rotate, the toothed belt 305 drives the moving slide 302 to move, and the moving slide 302 drives the retracting assembly 4 and the gantry assembly 5 to move to the position of the traffic cone, when the traffic cone enters the clamping area of ​​the corresponding manipulator assembly 506, the electric push rod 5062 of the corresponding manipulator assembly 506 extends, driving the clamping block a5067 and the clamping block b5068 to rotate inward and clamp the traffic cone, then the electric roller f drives the fixed sleeve 505 to rotate to the vertical direction, and then the traffic cone is collected. The manipulator assembly 506 on the fixed sleeve 505 rotates clockwise until the traffic cone clamped by the manipulator assembly 506 reaches the upper end of the conveyor belt c418, and the corresponding electric push rod 5062 of the manipulator assembly 506 contracts, driving the clamping block a5067 and the clamping block b5068 to rotate outward and release the traffic cone, and the traffic cone immediately falls onto the conveyor belt c418. At the same time, the electric roller f drives the manipulator assembly 506 on the fixed sleeve 505 to continue rotating until the manipulator assembly 506 rotates to the vertical direction again (i.e., the manipulator assembly 506 at the other end is located at the lower end). After the traffic cone falls onto the conveyor belt c418, it runs to the conveying assembly 2 driven by the conveyor belt c418, the conveyor belt b414, and the conveyor belt a405. The traffic cone is transported to the operator's side of the transport vehicle 1 driven by the electric roller a202. The operator stands behind the safety barrier 7, collects the traffic cone and stores it in the carriage of the transport vehicle 1, completing the collection of the traffic cone.

[0046] The folding process of the automatic traffic cone retracting device is as follows: after completing the collection of the traffic cone, the electric roller f drives the manipulator assembly 506 on the fixed sleeve 505 to rotate to the vertical direction, and then the hydraulic strut 425 begins to shrink, while driving the lower left ramp plate 410 and the lower right ramp plate 411 of the retracting assembly 4 and the gantry assembly to rotate upward until the top of the lower left ramp plate 410 and the lower right ramp plate 411 respectively contact the lower ends of the upper left ramp plate 401 and the upper right ramp plate 402, and then stop shrinking, completing the folding of the automatic traffic cone retracting device.
