Description

Technical Field

[0001] The invention relates to the field of special vehicles for highway maintenance industry, and in particular to a fallen traffic cone righting mechanism for an automatic traffic cone retracting and releasing vehicle. Background Art

[0002] Daily highway maintenance involves extensive tasks and is performed frequently. Substandard road surfaces require repairs when detected. With the improvement of people's livelihoods, increased motor vehicle usage, and the rapid development of logistics, the frequency of highway maintenance is increasing. During highway maintenance work, sections of road must be temporarily closed to protect equipment and personnel. A common method for this is to manually place traffic cones to direct traffic. This exposes workers and equipment to hazardous conditions during both the initial placement and final collection phases. Furthermore, long-distance placement is labor-intensive, making it difficult to attract young people to participate in today's mechanized, intelligent, and information-based world, as well as an aging population. Therefore, the cost of labor makes the design of an automated traffic cone placement and collection vehicle both necessary and urgent.

[0003] For example, a Chinese invention patent application entitled "Automatic Traffic Cone Retracting and Retracting Vehicle" and application number "2021106539097" published on August 19, 2021 recorded an automatic traffic cone placement and collection vehicle. Specifically, in the process of straightening the cones, the case proposed a cone baffle that can be retracted into the vehicle body. However, although the structure of this type of cone baffle can meet the basic requirements of straightening, after the cone is lifted up, if the operator makes an error or the straightening stroke is excessive, the originally straightened cone will be knocked down again by the cone baffle. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a mechanism for straightening fallen traffic cones, which can be applied to an automatic cone barrel retracting and releasing vehicle to straighten fallen traffic cones. It can straighten fallen traffic cones, making it easier for subsequent mechanisms to pick up the traffic cones from the road surface.

[0005] The technical solution of the present invention is as follows: the righting mechanism comprises a righting frame 10-1, a linear mechanism 10-2, two righting links 10-3 and a double V-rod 10-4 fixedly connected to the two righting links 10-3;

[0006] The top ends of a pair of righting links 10-3 are hinged to the righting frame 10-1, and the pair of righting links 10-3 remain parallel. The double V-bar 10-4 includes a fixed crossbar, a fixed support rod, and two arc-shaped fixed rods. The fixed crossbar is also hinged to the bottom ends of the pair of righting links 10-3. The two arc-shaped fixed rods are respectively fixedly connected to the bottom of the fixed crossbar through the fixed support rods and are in a downwardly arched arc shape.

[0007] One end of the linear mechanism 10-2 is hinged to the straightening frame 10-1, and the other end is hinged to the middle of one of the straightening links 10-3. The linear mechanism 10-2 is a linear power source, which drives a pair of straightening links 10-3 and the double V-rod 10-4 to swing up and down through the extension and retraction of the linear mechanism 10-2.

[0008] Furthermore, the top ends of the two righting links are hinged at different positions on the righting frame 10-1, the bottom ends of the two righting links are hinged at different positions on the fixed cross bar, and the two righting links 10-3 remain parallel, and a total of four hinge points at the top and bottom ends of the two righting links form a parallelogram.

[0009] Furthermore, the linear mechanism 10 - 2 and the fixed cross bar are on the same plane.

[0010] Furthermore, the arc-shaped fixing rod is arranged along the length direction of the cone barrel storage and placing vehicle 11.

[0011] To right a cone, the present invention extends the linear mechanism to a designated position, aligns the vehicle's direction of motion with the cone's axis, and then moves the double V-rod from the top of the fallen cone along the vehicle's direction of motion to the bottom. Finally, the cone is righted with the help of the cone retractor. Overall, the device boasts a compact structure, simple operation, and excellent coordination with the cone retractor. The specially shaped righting rod can be moved from a designated position to a designated location to re-right the fallen cone, effectively resolving the problem of righting a fallen cone.

[0018] In order to clearly illustrate the technical features of this patent, this patent is described in detail below through specific implementation methods and in combination with its accompanying drawings.

[0019] The present invention Figure 1-5 As shown, the straightening mechanism includes a straightening frame 10-1, a linear mechanism 10-2, two straightening links 10-3 and a double V-rod 10-4 fixedly connected to the two straightening links 10-3; the straightening frame 10-1 is fixedly installed on the frame of the cone barrel retracting and storing vehicle 11, and is located on the side or rear of the cone barrel retracting and storing vehicle 11 for the installation of other components.

[0020] There are two righting links 10-3, which are respectively provided with three hinge holes at both ends and the middle. Furthermore, the top ends of a pair of righting links 10-3 are hinged on the righting frame 10-1, and the pair of righting links 10-3 remain parallel. The double V-rod 10-4 includes a fixed cross bar, a fixed support rod and two arc-shaped fixed rods. The fixed cross bar is also hinged to the bottom ends of a pair of righting links 10-3. The two arc-shaped fixed rods are respectively fixedly connected to the bottom of the fixed cross bar through the fixed support rods and are in a downward arched arc shape; the double V-rod 10-4 is a special-shaped structural member, which is hinged on the two righting links 10-3 and is used to right the fallen cone barrel. Since the arc-shaped fixed rod is in a downward arched arc shape, the cone barrel will not be pushed down again after righting.

[0021] Both ends of the linear mechanism 10-2 are respectively provided with reaming holes. Furthermore, one end of the linear mechanism 10-2 is hinged to the straightening frame 10-1, and the other end is hinged to the middle part of one of the straightening links 10-3. The linear mechanism 10-2 is a linear power source, such as an electric push rod, a hydraulic cylinder, an air cylinder, etc. The linear mechanism can output the center distance of the reaming holes at both ends, and drive a pair of straightening links 10-3 and a double V-rod 10-4 to swing up and down through the extension and contraction of the linear mechanism 10-2, and can be put into a safe position in the transition state.

[0022] To right a cone, the linear structure is extended to a designated position, the vehicle's direction of motion is aligned with the cone's axis, and the double V-rod is moved from the top of the fallen cone to its bottom along the vehicle's direction of motion. Finally, the cone is righted with the help of the cone retractor. The device boasts a compact structure, simple operation, and excellent coordination with the cone retractor. The specially shaped righting rod, which moves from a designated position to a designated location, can be used to right a fallen cone, effectively resolving the problem of righting a fallen cone.

[0023] The top ends of the two righting links are hinged at different positions on the righting frame 10-1, and the bottom ends of the two righting links are hinged at different positions on the fixed cross bar. The two righting links 10-3 remain parallel, and the four hinge points at the top and bottom ends of the two righting links form a parallelogram.

[0024] The linear mechanism 10-2 and the fixed crossbar are on the same plane, so that the quadrilateral can be driven to swing up and down stably by the linear mechanism.

[0025] The arc-shaped fixing rod is arranged along the length direction of the cone barrel folding and unfolding vehicle 11. This makes it convenient for the operator to drive the arc-shaped fixing rod to straighten the fallen traffic cone by controlling the cone barrel folding and unfolding vehicle.

[0026] There are many specific implementation ways of the present invention. The above is only the preferred implementation method of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be considered as the scope of protection of the present invention.
