Description

Technical Field

[0001] This utility model relates to the field of traffic cone deployment and retraction, and more particularly to a rear-mounted multi-functional foldable cone deployment and retraction device. Background Technology

[0002] Traffic cones are a tool used in road construction to set up warning lines or construction lines.

[0003] Traditional traffic cones are mostly manually placed and removed, although some are automated. However, these devices have drawbacks:

[0004] 1. Cannot be folded, too bulky;

[0005] 2. The entire weight is borne on the carriage, resulting in significant vibration, and also placing high demands on the side walls of the carriage;

[0006] 3. The power requirements are too high and cannot be adjusted flexibly.

[0007] 4. Most importantly, a thorough review of all existing technologies reveals that all cones retract and extend in a straight line. However, for certain road closure areas that are rectangular, they need to be placed in an arc or at right angles, a task that current machinery cannot accomplish. On May 21, 2025, a search was conducted in the China Patent Publication Database using "traffic and cones and retraction and extension" as the abstract keywords, with the option to allow synonym expansion. The following documents were found, all addressing the aforementioned technical problems.

[0071] The guide space 21 can guide the traffic cones to the front of the overall support 2;

[0072] It also includes a flipping rod 22, which is arranged horizontally. The flipping rod 22 can block the upper part of the traffic cone so that after the traffic cone is flipped over, the hole at the bottom of the traffic cone is exposed and then hooked by the cone bottom hole insertion protrusion 16.

[0073] A further technical solution of this utility model is that a bottom support 17 is connected below the overall support 2, a bottom moving platform 18 is arranged below the bottom support 17, and a moving wheel is arranged below the bottom moving platform 18 to facilitate movement.

[0074] A further technical solution of this utility model is that both power arms 11 include a guide arc-shaped bottom 25, and the guide arc-shaped bottom 25 of the two power arms 11 can be used to guide the bottom of the traffic cone.

[0075] A further technical solution of this utility model is that the overall bracket is connected to a fixed bracket 15, and two guide wheels 24 are arranged at the bottom of the fixed bracket 15.

[0078] A further technical solution of this utility model is that the upper track 28 is located on the square frame 27, and a suspension structure 1 is fixedly connected to the square frame 27. The entire rear-mounted multi-functional foldable cone deployment and retraction device is suspended on the wall of the vehicle through the suspension structure 1. A further technical solution of this utility model is that the sprocket corresponding to the chain, and thus the corresponding power part, is a forward and reverse reversing motor. The method for deploying and retracting the foldable rear-mounted traffic cone is characterized in that...

[0079] Using any of the above-described rear-mounted multi-functional foldable cone retraction devices,

[0080] It includes the following steps:

[0086] As the vehicle moves backward, the bottom of the traffic cone is guided by the arc-shaped bottom 25. Then, the flipping rod 22 can block the upper part of the traffic cone, so that after the traffic cone is flipped over, the hole at the bottom of the traffic cone is exposed and then hooked by the cone bottom hole inserted into the protrusion 16.

[0087] The chain moves upwards continuously until it reaches the top, at which point a person removes the traffic cone.

[0088] The bottom moving platform 18 distributed the pressure on the carriage, allowing the traffic cones to be stably retracted.

[0091] A person exposes the hole at the bottom of the traffic cone, which is then inserted into the protrusion 16 and hooked.

[0092] The chain then moves downwards, reversing the path used to place the traffic cones on the ground.

[0093] As the vehicle moves forward, backward, or backward, the machine moves left and right via the upper guide rail, allowing the traffic cones in the transition section to form a pattern that is not linear.

[0095] Compared to existing technologies that "require excessive power and cannot be flexibly adjusted," this technology only requires a single forward and reverse motor, requires very little power, is convenient and safe, and is also low in cost.

[0096] Compared to existing technologies that "the entire weight is borne on the carriage, resulting in greater vibration and higher requirements for the carriage side walls," this technology has a platform at the bottom for load-bearing, making it more stable, having less impact on the vehicle, and being less affected by vehicle vibration.

[0097] Compared to existing technologies, "most importantly, all existing technologies involve the straight-line deployment and retraction of cones. However, for certain road closure areas that are rectangular, they need to be placed in an arc or at a right angle, which existing machinery cannot accomplish." This technology innovatively enables right-angle or arc placement. Attached Figure Description
