Abstract
Description
Technical Field
[0001] This utility model relates to the field of road safety facility installation, specifically to a clamping mechanism for traffic cones. Background Technology
[0002] With the rapid development of traffic engineering and road maintenance, traffic cones (also known as road cones or traffic cones) are widely used as an important temporary traffic warning facility in road construction, accident scenes, and traffic diversion. Traditional manual placement and retrieval of traffic cones is inefficient and poses safety hazards. Therefore, automated traffic cone placement and retrieval equipment is gradually becoming the trend of industry development.
[0003] In automated placement and retrieval equipment, traffic cones are typically stored vertically stacked, with the bottom of one cone inserted into the interior of another to save space and facilitate mechanical gripping. However, due to the cone-shaped structure and material properties (such as rubber or plastic), the two cones can easily stick together due to friction and air pressure. This sticking can cause the mechanical gripping device to pick up multiple cones at once, affecting the placement accuracy and efficiency of the automated equipment, and may even lead to equipment malfunction or damage to the cones.
[0004] Currently, some technologies have attempted to solve the problem of traffic cone adhesion. For example, Chinese patent CN107288056A discloses a pneumatic stripping device for traffic cones, which achieves the stripping of traffic cones; or an anti-stick coating is added inside the traffic cone. However, the above solutions are complex in structure, or have high cost, and are difficult to achieve fast and reliable separation while ensuring stability.
[0005] In addition, since the heads of traffic cones are usually made of smooth plastic, mechanical grippers often lack a reliable point of force when gripping, making them prone to deformation, which can lead to slippage or unstable gripping, further reducing the reliability of automated operation. Utility Model Content
[0006] The purpose of this invention is to provide a clamping mechanism for traffic cones. By automatically creating gaps when traffic cones are stacked, it effectively avoids tight contact between the upper and lower traffic cones, thereby ensuring that the mechanical clamping device only grabs a single traffic cone at a time and provides a reliable point of force for the clamping device during gripping. This solution has a simple structure and low cost, and can significantly improve the reliability and working efficiency of automated loading and unloading equipment.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] This utility model provides a clamping mechanism for traffic cones, including a detachably connected cone head connector and a cone head connector seat;
[0009] The bottom of the cone-shaped connector is provided with a cone-shaped guide cone, and the cone-shaped connector is provided with a receiving space for accommodating the cone-shaped connector.
[0010] The cone-shaped connector is provided with a cone-shaped cavity that mates with the cone-shaped guide cone.
[0011] The diameter of the conical cavity is larger than the outer diameter of the conical guide cone, and the cone angle of the conical cavity is smaller than the cone angle of the conical guide cone.
[0012] In a further improvement, the cone connector and cone connector seat are mounted on the top of the traffic cone;
[0013] The cone head connector is embedded in the inner cavity of the top of the traffic cone, and the cone head connector is located outside the head of the traffic cone. The traffic cone is fixed by connecting the cone head connector and the cone head connector.
[0014] Further improvements include ensuring that the center of the conical guide cone and the center of the conical cavity are perpendicular to each other in the same vertical plane, which can ensure that the traffic cones maintain a straight vertical alignment when stacked.
[0015] In a further improvement, the cone connector is exposed at the top of the traffic cone, providing a clamping point for holding the traffic cone.
[0016] In a further improvement, the entrance end of the conical cavity is provided with a guide chamfer, which facilitates the insertion of the conical guide cone.
[0017] As a further improvement, the bottom of the cone head connector is provided with a radially limiting flange, which is used to prevent the cone head connector from falling off the traffic cone.
[0018] In a further improvement, the cone angle of the conical cavity is 0.1° to 1.4° smaller than the cone angle of the conical guide cone.
[0019] In a further improvement, the diameter of the conical cavity is 0.1 mm to 1 mm larger than the outer diameter of the conical guide cone.
[0020] In a further improvement, the cone head connector is provided with an internal thread, and the cone head connector is provided with a corresponding external thread, and the cone head connector is threadedly connected to the cone head connector.
[0021] Further improvements include the following: when traffic cones are stacked vertically, the cone-shaped guide cone of the upper traffic cone is inserted into the cone-shaped cavity of the lower traffic cone, and a gap is formed between adjacent traffic cones to prevent them from sticking together.
[0022] Compared with the prior art, this utility model achieves the following technical effects:
[0023] The modular design of the cone head connector and cone head connector effectively reduces the adhesion problem that occurs when traffic cones are stacked. First, the structure of each component is simple, which facilitates subsequent processing and manufacturing. Second, the connection between the cone head connector and the cone head connector is quick and convenient, and the process of use is simple. Finally, in subsequent installation and maintenance, only the single damaged component needs to be replaced, resulting in low maintenance costs.
[0024] This invention creates a gap by using the difference in aperture between the conical cavity and the conical guide cone to prevent the negative pressure that causes adsorption when traffic cones are stacked. By setting the gap, the conditions for generating negative pressure are eliminated, thus solving the adsorption problem. In addition, by creating a gap by using the difference in cone angle between the conical cavity and the conical guide cone, it is ensured that when traffic cones are stacked, the lower surface of the cone head connector and the upper surface of the cone head connector can form a stable supporting contact, solving the frictional adhesion problem in traditional methods.
[0025] The cone-shaped connector of this invention provides a clamping force point for automated equipment, which can further improve the stability and reliability during clamping and solve the problem of slippage caused by the low strength and smooth surface of plastic traffic cones. The structure of this invention is simple and can be adapted to most specifications of traffic cones. Attached Figure Description

[0031] The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Rather, the embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0032] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0033] See Figure 1 This embodiment provides a clamping mechanism for traffic cones, including a detachably connected cone head connector 1 and a cone head connector seat 2; the bottom of the cone head connector seat 2 is provided with a conical guide cone 4, and the cone head connector seat 2 is provided with a receiving space for accommodating the cone head connector 1; the cone head connector 1 is provided with a conical cavity 3 that cooperates with the conical guide cone 4; wherein the diameter of the conical cavity 3 is larger than the outer diameter of the conical guide cone 4, and the cone angle of the conical cavity 3 is smaller than the cone angle of the conical guide cone 4.
[0034] The clamping mechanism in this embodiment consists of a cone-shaped connector 1 and a cone-shaped connector 2. The cone-shaped connector 2 is a truncated cone with internal threads inside its cavity and a cone-shaped guide cone 4 extending from its bottom. The cone-shaped guide cone 4 is truncated cone-shaped. The cone-shaped connector 2 is provided with a limiting flange 6, which is arranged along the radial direction of the cone-shaped connector 2, and the bottom of the limiting flange 6 is the cone-shaped guide cone 4.
[0035] The specific dimensions of the cone head connector 2 and the cone-shaped guide cone 4 in the embodiment, such as diameter, height, top diameter, bottom diameter, cone angle, etc., can be determined according to the size of the traffic cone 7 to be installed, and are not limited in this embodiment; the cone-shaped guide cone 4 is set to be inserted into the cone cavity 3 of the cone head connector 1, which can prevent the traffic cones 7 stacked on top of each other from sticking together.
[0036] The embodiment provides a limiting flange 6 to ensure that the cone head connector 2 is installed in the traffic cone 7. The limiting flange 6 can achieve axial limiting of the cone head connector 2 and prevent the cone head connector 2 from falling off the traffic cone 7.
[0037] In the embodiment, the cone head connector 2 and the cone head connector 1 are preferably connected by threads, but are not limited to this. They can also be connected by spiral grooves or trapezoidal teeth, depending on actual needs.
[0038] See Figure 1 In this embodiment, the top of the cone connector 1 is provided with a cone cavity 3 that mates with the cone guide cone 4. The entrance end of the cone cavity 3 is also provided with a guide chamfer 5, which facilitates the positioning of the cone guide cone 4 and the cone cavity 3, so that the cone guide cone 4 can be smoothly inserted into the cone cavity 3. The bottom of the cone connector 1 is provided with an external thread that matches the internal thread of the cone connector 2.
[0039] In this embodiment, the cone connector 1 and the cone connector 2 are made of metal or hard material, such as aluminum alloy.
[0040] It should be noted that, in the embodiment, the diameter of the conical cavity 3 is 0.1 mm to 1 mm larger than the outer diameter of the conical guide cone 4, and the cone angle of the conical cavity 3 is 0.1° to 1.4° smaller than the cone angle of the conical guide cone 4.
[0041] See Figure 2 In the connection process of the cone connector 1 and the cone connector 2 in this embodiment, a gap can be formed between the cone connector 1 and the cone connector 2. The gap is occupied by the traffic cone 7 in actual use. Therefore, when an automated device, such as an electric gripper, applies a radial clamping force to the upper traffic cone 7, the lower traffic cone 7 does not stick or fall off due to the existence of the gap, which facilitates the clamping of the traffic cone 7.
[0042] See Figure 3 In this embodiment, during installation, the clamping mechanism is fixed to the top of the traffic cone 7, specifically:
[0043] The cone connector 2 is embedded in the traffic cone 7, and the cone connector 1 protrudes from the top of the traffic cone 7. During assembly:
[0044] Insert the cone head connecting seat 2 into the bottom opening of the traffic cone 7, so that the limiting flange 6 is tightly attached to the inner wall of the cone;
[0045] Insert the cone connector 1 into the opening at the top of the traffic cone 7, aligning its external thread with the internal thread in the cone connector 2; tighten the internal and external threads, and check the exposed height of the cone connector 1 to adapt to different sizes of traffic cones 7.
[0046] See Figure 4 In this embodiment, when multiple traffic cones 7 are stacked, the cone-shaped guide cone 4 of the upper traffic cone 7 will be inserted into the cone-shaped cavity 3 of the lower traffic cone 7, thereby realizing the stacking of multiple traffic cones 7.
[0047] Because the diameter of the conical cavity 3 is larger than the outer diameter of the conical guide cone 4, and the cone angle of the conical cavity 3 is smaller than the cone angle of the conical guide cone 4, it is ensured that the conical guide cone 4 of the upper traffic cone 7 can be completely and smoothly inserted into the conical cavity 3 of the lower traffic cone 7 during the stacking of traffic cones 7. In addition, the bottom surface of the cone head connecting seat 2 of the upper traffic cone 7 and the upper surface of the cone head connecting head 1 of the lower traffic cone 7 form a stable supporting contact, thereby ensuring that a gap is formed between the upper traffic cone 7 and the lower traffic cone 7. This gap ensures that the two traffic cones 7 do not contact each other and avoids adhesion between the traffic cones 7.
[0048] In addition, when the upper traffic cone 7 and the lower traffic cone 7 are stacked, the cone-shaped guide cone 4 and the cone-shaped cavity 3 can rely on the self-centering property of the cone to ensure that the center of the cone-shaped guide cone 4 and the cone-shaped cavity 3 are perpendicular to the same vertical plane, so that each traffic cone 7 is automatically aligned and maintains a straight vertical arrangement when stacked.
[0049] The clamping mechanism in this embodiment has sufficient strength and rigidity to ensure that the clamping force is sufficient to clamp the traffic cone when the gripper and other mechanisms are clamping, thereby improving the reliability and convenience of automatic retraction and deployment of the traffic cone.
