For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.
[0026] As shown in Figures 1 to 5 The utility model provides a base support leg for mobile guardrail, including support seat 1, be equipped with antiskid limiting piece 2 on support seat 1, antiskid limiting piece 2 is used to increase the friction force of support seat 1 and ground,
[0027] Wherein, the antiskid limiting piece 2 at least includes the limiting portion 21 being arranged at the bottom of the support seat 1 and protruding the bottom of the support seat 1.
[0028] The utility model embodiment increases the friction force between support seat and ground by setting antiskid limiting piece at the bottom of support seat, significantly improves the stability of guardrail, especially by designing limiting portion as protruding the bottom of support seat, makes the contact area of base and ground increase, enhances the friction effect, prevents guardrail from displacement or collapse when being stressed or impacted, compared with the traditional way of increasing the weight of base or external support, the scheme can improve the stability of guardrail, and reduces the cost and improves portability.
[0029] In addition, in the mobile guardrail, the base support leg of the embodiment can also solve the problem that the concrete structure is easy to crumble.
[0030] Optionally, the number of limiting portions 21 is at least two.
[0031] This embodiment effectively increases the friction between the support base and the ground by setting at least two limiting parts on the support legs of the movable guardrail, which significantly improves the stability of the guardrail. The multiple limiting parts are distributed in different positions on the base, so that the guardrail can distribute the pressure more evenly when subjected to external forces, avoiding the local overload problem that may be caused by a single limiting part. At the same time, the setting of multiple limiting parts further enhances the guardrail's anti-overturning ability. When subjected to impact, it can effectively prevent the guardrail from shifting or collapsing, thereby improving the safety and reliability during use.
[0032] Specifically, on relatively flat ground, the two limiting parts can be arranged symmetrically to maximize the friction area, while on irregular or undulating ground, the number of limiting parts can be increased and their distribution position adjusted to better adapt to the shape of the ground.
[0033] In addition, the material of the limiting part can be optimized according to the specific environment. For example, a material with a high coefficient of friction can be used on wet and slippery ground, while a material with strong wear resistance can be selected on dry ground, thereby further improving the friction effect and the stability of the guardrail.
[0034] Optionally, the protruding length of the limiting part 21 may be the same as or different from the bottom of the support base 1.
[0035] This embodiment provides a more flexible friction enhancement effect by designing the protruding length of the limiting part to be the same as or different from the bottom of the support base. The protruding length of the limiting part can be designed according to actual needs. If a uniform friction distribution is required, the protruding length of the limiting part can be made consistent. If a staggered distribution is required to adapt to irregular ground, different protruding lengths can be designed. This can effectively improve the stability of the guardrail on different ground surfaces. The limiting part can provide more reasonable contact pressure according to the ground shape and external force, avoiding the guardrail from shifting or tilting due to uneven friction, and further enhancing the guardrail's anti-overturning ability and safety.
[0036] Optionally, the limiting part 21 can be one or a combination of cylindrical, conical, barbed, and frustum shapes.
[0037] This embodiment significantly enhances the stability and friction of the guardrail by designing the limiting part as one or a combination of cylindrical, conical, barbed, and frustum shapes: the limiting part of different shapes can adapt to different ground conditions and provide stronger anti-overturning ability.
[0038] Specifically, the cylindrical limiting part can provide consistent friction on a flat ground. Since the protruding length of the cylindrical limiting part is relatively consistent, it can ensure stable support force in the case of large-area contact with the ground, and thus is suitable for use in an environment where the ground is relatively flat and uniform. In addition, the cylindrical design also has good wear resistance and carrying capacity, and is not easy to deform after long-term use, which can effectively improve the stability of the guardrail.
[0039] The structure of the conical limiting part gradually shrinks from the large end to the small end, like an inverted cone. When the conical limiting part contacts the ground, its small end can better embed into uneven ground, forming stronger friction. The conical limiting part can adapt to complex terrain by gradually increasing the contact area, and is particularly suitable for use on ground with slight bumps and depressions, such as gravel roads, mountains or irregular urban roads. The limiting part of this shape performs well in dispersing external forces and can effectively reduce the risk of guardrail tilting or displacement.
[0040] The outer shape of the barb-shaped limiting part is similar to a fish hook, with a sharp head and barbs around the head. The barb-shaped limiting part can firmly hook the ground and provide strong friction and stability. Unlike the conical limiting part, the barbs of the barb-shaped limiting part can more effectively embed when contacting the ground, thereby preventing the displacement or tilting of the guardrail. This shape is particularly suitable for soft or uneven ground and can improve friction to prevent the guardrail from sliding or tilting due to loose ground. The barb-shaped limiting part is often used in environments that require high-strength fixation to ensure that the guardrail is stable and immovable under complex or harsh ground conditions. The barb-shaped limiting part can be a reverse zigzag spike, a non-slip spike, a non-slip hook, or other spikes with the same effect.
[0041] The circular truncated cone-shaped limiting part is composed of a larger bottom circular area and a circular part that gradually narrows upwards, resembling a circular truncated cone. The circular truncated cone-shaped limiting part has good stability and can provide a large contact area when contacting the ground, improving friction and enhancing anti-overturning capability. The design of the circular truncated cone-shaped limiting part can ensure strong friction while also being adaptable to different ground contacts. On irregular ground, the circular truncated cone-shaped limiting part can better disperse external forces and provide uniform support. At the same time, due to its stable geometry, it can also effectively reduce the problem of guardrail displacement caused by external impact.
[0042] Optionally, the support base 1 includes a support bottom plate 11 and a support upper shell 12 located on the support bottom plate 11.
[0043] In this embodiment, the support bottom plate 11 provides a solid foundation support, and the support upper shell 12 enhances the anti-overturning capability of the guardrail through effective combination with the bottom plate, ensuring the firmness of the support base and effectively dispersing external forces to improve the adaptability of the guardrail in different environments and ensure stability and durability during long-term use.
[0044] Optionally, the limiting part 21 protrudes 10-30mm from the bottom of the support base plate 11.
[0045] In the embodiment of the utility model, the protruding length of the limiting part effectively increases the contact area between the support seat and the ground, thereby enhancing the friction force, preventing the guardrail from being displaced or tilted when subjected to external impact, and preferably, the 15-20mm protruding length can ensure sufficient stability while avoiding unnecessary friction or wear caused by excessive protrusion. In addition, this design can also adapt to different ground conditions and ensure that the guardrail maintains good stability in variable environments, thereby prolonging the service life.
[0046] Optionally, the horizontal inclined surface of the support upper shell 12 is designed to be inclined, and the included angle between the horizontal inclined surface of the support upper shell 12 and the adjacent road is α, and the included angle α is 100°-150°.
[0047] Preferably, the included angle between the horizontal inclined surface of the support and the adjacent road is 120°-135°.
[0048] In this embodiment, the included angle between the horizontal inclined surface of the support upper shell 12 and the adjacent road is α, and the included angle α is 100°-150°, which effectively improves the safety performance of the guardrail. The inclined surface design allows the impact force to be dispersed and transferred along the inclined surface direction when a vehicle or a pedestrian accidentally hits the guardrail, thereby significantly reducing the impact force caused by direct impact. This not only reduces the force impact when hitting, but also reduces the damage caused by hitting.
[0049] Optionally, a chamfer transition is provided at the connection between the support upper shell 12 and the support base plate 11.
[0050] In this embodiment, the chamfer transition can effectively eliminate sharp edges and reduce damage and wear caused by direct impact of the edges. In addition, the chamfer design also helps to disperse the impact force transmitted through these joints, thereby increasing the impact resistance of the structure. When the guardrail is subjected to impact during use, the chamfer transition can reduce the stress concentration at the impact site, thereby prolonging the service life of the guardrail and reducing maintenance costs.
[0051] Optionally, the anti-skid limiting part 2 further comprises a limiting support part 22 connected to the limiting part 21, and the limiting support part 22 and the limiting part 21 are respectively located on both sides of the support base plate 11.
[0052] In this embodiment, the limiting support part 22 can provide additional support force on the other side of the support bottom plate, ensuring that the limiting part 21 effectively contacts the ground, enhancing the stability and overturning resistance of the guardrail. This design not only optimizes the friction force distribution, avoiding displacement of the guardrail due to uneven external force, but also adapts to different ground conditions, improving the performance of the guardrail in complex environments.
[0053] In practical applications, the structure of the limiting support part 22 can be designed to be adjustable, so as to adjust the support force and friction force distribution according to the actual use scene. By designing an adjustable limiting support part, users can flexibly adjust the height and angle of the support part according to the friction characteristics of different ground and use requirements, to achieve the best friction effect.
[0054] In addition, more wear-resistant or corrosion-resistant materials such as high-strength alloys or special plastics can also be considered, which can greatly prolong the service life of the limiting support part and the limiting part, especially suitable for harsh weather conditions or long-term outdoor use.
[0055] Optionally, the limiting support part 22 and the limiting part 21 are designed as an integrated structure, and the positions of the two are fixed through built-in connecting parts, thereby simplifying the production process and installation process. Through this scheme, the overall structure is more compact, reducing the number of parts and improving manufacturing efficiency.
[0056] Specifically, the movable guardrail also includes a concrete precast block, and the anti-skid limiting part 2 can be directly embedded in the concrete precast block. By pre-burying the anti-skid limiting part 2 when pouring concrete, stable fixation is achieved. This method has strong fixation and can ensure that the anti-skid limiting part 2 is firmly embedded in the concrete and is not prone to displacement or loosening. Moreover, by direct embedding, the friction between the anti-skid limiting part 2 and the concrete is enhanced, effectively improving the stability and overturning resistance of the guardrail bottom.
[0057] Specifically, a hole is reserved at the bottom of the movable guardrail, and the anti-skid limiting part 2 is fixed by using the planting bar technology. The planting bar is a common reinforcing method, which inserts steel bars into the reserved hole and uses professional adhesives or other reinforcing methods to firmly plant the anti-skid limiting part 2 at the bottom of the guardrail. This method can avoid the complexity of direct contact with concrete, while enhancing the connection stability of the guardrail and the anti-skid limiting part 2.
[0058] Specifically, a support seat is provided at the bottom of the guardrail, and the anti-skid limiting part 2 is fixed to the support seat by welding or bolts. The support seat can effectively bear external force and evenly distribute the force of the anti-skid limiting part 2 to the entire guardrail structure, ensuring the firm connection of the anti-skid limiting part 2 and the guardrail, and effectively improving the overall wind resistance, shock resistance and overturning resistance.
[0059] Specifically, the anti-skid limiting piece 2 can be fixed on the steel plate or other hard base plate alone to form an independent fixed unit, and the unit is fixed to the bottom of the guardrail through bolts or other fasteners, and the advantage of this mode is that the position and quantity of the anti-skid limiting piece 2 can be customized and designed according to specific requirements, so that the friction and stability of the guardrail can be maximized.
[0060] Reference Figure 5 Optionally, the support seat of the utility model can also be designed as a pair, respectively located on both sides of the mobile guardrail along the length direction, and the pair of support seats can be embedded into the cement pouring prefabricated block of the mobile guardrail through cement pouring, through this design, the installation mode of the support seat becomes more stable and firm, and the anti-displacement and anti-overturning ability of the guardrail can be effectively enhanced.

Therefore: any equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
