Description

Technical Field

[0001] The present invention relates to the technical field of guardrails, and in particular to a base for a mobile guardrail. Background Art

[0002] Guardrails are widely used in road traffic, industrial facilities, construction sites and other fields. They are mainly used to limit the range of activities of people and vehicles and ensure safety. In road traffic, guardrails, as road boundary markers, can effectively prevent pedestrians or vehicles from entering dangerous areas and avoid accidents. With the advancement of urbanization, the demand for guardrails is increasing. Therefore, how to improve the stability and safety of guardrails during use has become an important research direction for guardrail design.

[0003] However, in the existing guardrail design, the method of increasing friction to improve its stability and safety is relatively simple, mainly relying on using rubber, plastic and other materials as the padding at the bottom of the guardrail, or by installing anti-slip pads at the bottom to increase the friction with the ground. However, these traditional methods have certain limitations. For example, common anti-slip pads or rubber pads can often only provide limited friction, and over time, the material may age and wear, resulting in weakened friction, causing the guardrail to tilt, slide and other unstable phenomena in strong winds or uneven ground. Summary of the invention

[0004] In order to solve the technical defects mentioned in the above background technology, the purpose of the present invention is to provide a base for a mobile guardrail, including a support seat, on which an anti-skid component is provided, the anti-skid component is used to increase the friction between the support seat and the ground, the anti-skid component includes an anti-skid lining and an anti-skid limiter, the anti-skid limiter and the anti-skid lining are used to increase the friction between the support seat and the ground, wherein: The anti-skid lining at least includes an anti-skid pad arranged at the bottom of the support seat, and the anti-skid limiting component at least includes a limiting portion arranged at the bottom of the support seat and protruding from the bottom of the support seat.

[0005] Furthermore, it also includes a support rod group, the two support seats are arranged opposite to each other and connected by the support rod group, the two support seats and the support rod group are surrounded by a base frame installation cavity, and the installation cavity is used to accommodate the movable guardrail frame.

[0006] Furthermore, the support seat includes a support base plate and a support upper shell located on the support base plate, and a chamfer is provided at a connection between the support upper shell and the support base plate.

[0007] Furthermore, the support rod group includes a first bending rod, a second bending rod and a plurality of supporting straight rods, the first bending rod and the second bending rod are relatively connected to two relatively arranged supporting upper shells to form a main mounting port of a movable guardrail frame, for allowing the movable guardrail frame to extend from the main mounting port of the movable guardrail frame into the mounting cavity for connection, and the plurality of supporting straight rods are connected to two relatively arranged supporting bottom plates, and the supporting straight rods respectively form side mounting ports of the movable guardrail frame on both sides with the first bending rod and the second bending rod, for allowing the movable guardrail frame to extend from the side mounting ports of the movable guardrail frame into the mounting cavity for connection.

[0008] Furthermore, the number of the limiting portions is at least two, and the protruding lengths of the plurality of limiting portions relative to the bottom of the support seat may be consistent or different.

[0009] Furthermore, the anti-skid pad is provided with friction grooves at least on the part in contact with the road surface, and the anti-skid pad is also provided with a flange and a through hole, the flange is used to cover the connection between the support upper shell and the support bottom plate, the shape of the flange matches the contour of the support upper shell and the support bottom plate, and the through hole is used for the limiting portion to extend the anti-skid pad.

[0010] Furthermore, the transverse inclined surface and the side surface of the supporting upper shell are both inclined, and the angle between the transverse inclined surface of the supporting upper shell and the adjacent road is α, and the angle α is 100°-150°.

[0011] Furthermore, the plurality of limiting portions are in a cylindrical, conical, barbed, or truncated cone shape or a combination thereof.

[0012] Furthermore, the anti-slip limiter also includes a limit support portion connected to the limit portion, and the limit support portion and the limit portion are respectively located on two sides of the support base plate.

[0013] Furthermore, the two supporting straight rods are equidistantly arranged on both sides of the limiting portion.

[0014] Compared with the prior art that relies on anti-skid pads or liners of a single material, the present invention adds an anti-skid limiter on the basis of the anti-skid lining. The protruding design of the limiter further increases the contact area between the base and the ground, providing stronger friction, ensuring that the guardrail remains stable in harsh environments such as wind or uneven ground.

[0015] In addition, the anti-skid assembly of the present invention not only improves the friction force, but also solves the problem of reduced friction force due to material aging and wear of traditional anti-skid pads. The design of the anti-skid stopper avoids serious damage to the road surface, avoids the scratching of the road surface by traditional metal nails and hard parts, reduces maintenance costs and prolongs the service life of the road surface.

Unless otherwise specified, "plurality" means two or more.

[0023] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] like Figures 1 to 7 As shown, the embodiment of the present application provides a base for a mobile guardrail, including a support base 1, on which an anti-skid component 2 is provided, and the anti-skid component 2 is used to increase the friction between the support base 1 and the ground, and the anti-skid component 2 includes an anti-skid lining 21 and an anti-skid stopper 22, and the anti-skid stopper 22 and the anti-skid lining 21 are used to increase the friction between the support base 1 and the ground, wherein: The anti-skid lining 21 at least includes an anti-skid pad 211 disposed at the bottom of the support seat 1 , and the anti-skid limiting member 22 at least includes a limiting portion 221 disposed at the bottom of the support seat 1 and protruding from the bottom of the support seat 1 .

[0025] Compared with the prior art that relies on anti-skid pads or liners of a single material, the present invention adds an anti-skid limiter on the basis of the anti-skid lining. The protruding design of the limiter further increases the contact area between the base and the ground, providing stronger friction, ensuring that the guardrail remains stable in harsh environments such as wind or uneven ground.

[0026] In addition, the anti-skid assembly of the present invention not only improves the friction force, but also solves the problem of reduced friction force due to material aging and wear of traditional anti-skid pads. The design of the anti-skid stopper avoids serious damage to the road surface, avoids the scratching of the road surface by traditional metal nails and hard parts, reduces maintenance costs and prolongs the service life of the road surface.

[0027] Optionally, it also includes a support rod group 3, the two support seats 1 are arranged opposite to each other and connected by the support rod group 3, the two support seats 1 and the support rod group 3 are arranged to form a base frame installation cavity 4, and the installation cavity 4 is used to accommodate the mobile guardrail frame.

[0028] The embodiment of the present invention sets a support rod group 3 between two support seats 1 and connects them into a stable whole to form a base frame installation cavity 4, which can effectively accommodate the mobile guardrail frame, enhance the overall rigidity and stability of the base, and ensure the stability and wind resistance of the guardrail during use. In addition, the support rod group 3 not only provides additional supporting force, but also optimizes the structural distribution of the base, so that the overall weight of the mobile guardrail is more uniform, avoiding tilting or imbalance caused by weight concentration.

[0029] Preferably, the support rod group 3 also includes an adjustment structure, which is a telescopic support rod or a spiral adjustment device. The adjustment structure allows the distance between the support seat 1 and the support rod group 3 to be adjusted according to specific ground conditions and usage requirements. This adjustable structure not only makes the base more flexible, but also improves the stability of the guardrail on different terrains. For uneven ground, users can ensure that the contact surface between the base and the ground remains stable at all times by adjusting the length of the support rod, thereby further improving the use effect of the guardrail.

[0030] Optionally, the support base 1 includes a support base plate 11 and a support upper shell 12 located on the support base plate 11 , and a chamfer 13 is provided at a connection between the support upper shell 12 and the support base plate 11 .

[0031] In this embodiment, the design of the chamfer 13 can effectively reduce the stress concentration at the connection between the supporting base plate 11 and the supporting upper shell 12, and enhance the stability and durability of the structure. The chamfer 13 not only makes the connection smoother, avoiding stress concentration or physical damage that may be caused by sharp corners, but also improves the impact resistance of the support base. During the use of the guardrail, the connection part of the support base 1 can withstand greater external forces without being prone to breakage or deformation, thereby ensuring the long-term stability of the guardrail.

[0032] Optionally, the support rod group 3 includes a first bending rod 31, a second bending rod 32 and a plurality of supporting straight rods 33, the first bending rod 31 and the second bending rod 32 are relatively connected on two relatively arranged supporting upper shells 12 to form a main mounting port 5 of a movable guardrail frame, for allowing the movable guardrail frame to extend from the main mounting port 5 of the movable guardrail frame into the mounting cavity 4 for connection, and the plurality of supporting straight rods 33 are connected to the two relatively arranged supporting bottom plates 11, and the supporting straight rods 33 respectively form side mounting ports 6 of the movable guardrail frame on both sides with the first bending rod 31 and the second bending rod 32, for allowing the movable guardrail frame to extend from the side mounting ports 6 of the movable guardrail frame into the mounting cavity 4 for connection.

[0033] The support rod group 3 of the embodiment of the present invention includes a first bending rod 31, a second bending rod 32 and a plurality of supporting straight rods 33. The design further strengthens the function of the support seat 1. The first bending rod 31 and the second bending rod 32 form a main mounting opening 5 of the movable guardrail frame by connecting the supporting upper shell 12. The main mounting opening 5 of the movable guardrail frame allows the guardrail frame to easily extend from the main opening into the mounting cavity 4 and be firmly connected. The plurality of supporting straight rods 33 are respectively connected to the two supporting base plates 11, and further provide lateral support for the movable guardrail frame through the side mounting opening 6 formed with the first bending rod 31 and the second bending rod 32. This embodiment not only improves the stability of the structure through multi-point connection and support, but also enhances the overall bearing capacity, thereby ensuring the safety and stability of the movable guardrail in various environments. Moreover, through the reasonable coordination of the main mounting opening and the side mounting opening, the installation process of the guardrail frame becomes simpler and more reliable, thereby improving the overall use efficiency.

[0034] Specifically, the first bending rod 31 and the second bending rod 32 are connected to support the upper shell 12 to form a main mounting port 5 of the movable guardrail frame. The main mounting port 5 of the movable guardrail frame enables the guardrail frame to smoothly extend from the main mounting port into the mounting cavity 4 for connection. Through this structure, the installation of the guardrail frame is more stable and can maintain good structural stability after installation, and is not prone to displacement or tilting.

[0035] Specifically, the support straight rod 33 is connected to the support base plate 11 and is connected to the first bending rod 31 and the second bending rod 32 to form a side mounting port 6 of the movable guardrail frame. The side mounting port 6 of the movable guardrail frame provides additional support and fixing points for the guardrail frame, which prevents the guardrail from lateral shaking during use and improves the stability of the overall structure. Through the supporting effect of the support straight rod 33, the guardrail frame can be evenly stressed during the entire installation process, and will not cause structural deformation or tilt due to local uneven stress.

[0036] Specifically, for the guardrail body, the cooperation between the main installation opening 5 of the mobile guardrail frame and the side installation opening 6 of the mobile guardrail frame enables the guardrail frame to be quickly and accurately installed on the base, without the need for complicated positioning operations during the installation process, thereby saving time and labor.

[0037] Optionally, there are at least two limiting portions 221 , and the protruding lengths of the plurality of limiting portions 221 relative to the bottom of the support base 1 may be consistent or different.

[0038] This embodiment provides a more flexible friction enhancement effect by designing the protruding length of the limiting part to be consistent or different relative to the bottom of the support seat: the protruding length of the limiting part can be designed according to actual needs. If uniform friction distribution is required, the protruding length of the limiting part can be made consistent; if staggered distribution is required to adapt to irregular ground, different protrusion lengths can be designed. This can effectively improve the stability of the guardrail on different ground surfaces. The limiting part can provide a more reasonable contact pressure according to the ground shape and external force, thereby avoiding displacement or tilting of the guardrail due to uneven friction, and further enhancing the anti-overturning ability and safety of the guardrail.

[0039] Optionally, the anti-skid pad 211 is provided with friction grooves at least in the part in contact with the road surface, and the anti-skid pad 211 is also provided with a flange 212 friction groove; 213 and a through hole 214, the flange 212 friction groove; 213 is used to cover the connection between the support upper shell 12 and the support bottom plate 11, the shape of the flange 212 friction groove; 213 matches the contour of the support upper shell 12 and the support bottom plate 11, and the through hole 214 is used for the limiting portion 221 to extend out of the anti-skid pad 211.

[0040] The anti-skid pad 211 in the embodiment of the present invention is designed to significantly enhance the anti-skid effect by providing friction patterns on the part in contact with the road surface, thereby ensuring the stability of the base under different ground conditions. At the same time, the flange 212 and the friction patterns 213 on the anti-skid pad 211 can not only cover the connection between the supporting upper shell 12 and the supporting bottom plate 11, further enhancing the friction between the ground, but also effectively avoid the safety hazards caused by loosening or displacement of the connection parts during the use of the guardrail. The design of the through hole 214 allows the limiting part 221 to smoothly extend out of the anti-skid pad 211, thereby enhancing the limiting effect, ensuring the stable connection between the base and the ground, and improving the safety and stability of the overall structure.

[0041] Specifically, the friction pattern can be designed in a variety of different forms to adapt to different usage environments and needs. For example, it can be designed as a cross texture, which is composed of multiple intersecting lines and provides multi-directional friction, or a dot texture, which is composed of multiple raised dots. These dots provide friction while also having good elasticity and cushioning properties. In addition, a wavy texture is also an option. The continuous undulating shape of the wavy line helps to increase friction and disperse pressure. Optionally, the transverse inclined surface and the side surface of the supporting upper shell 12 are both inclined, and the angle between the transverse inclined surface of the supporting upper shell 12 and the adjacent road is α, and the angle α is 100°-150°.

[0042] In this embodiment, the angle between the horizontal inclined surface supporting the upper shell 12 and the adjacent road is α, and the angle α is 100°-150°, which effectively improves the safety performance of the guardrail: the inclined slope design allows the slope to guide the impact force to be dispersed and transferred along the slope direction when a vehicle or pedestrian accidentally hits the guardrail, thereby significantly reducing the impact force caused by the direct impact, which not only reduces the force impact during the collision, but also reduces the damage caused by the collision.

[0043] Preferably, the angle between the transverse inclined surface of the support and the adjacent side road is 120°-135°.

[0044] Optionally, the plurality of limiting portions 221 are in a cylindrical, conical, barb-shaped, or truncated cone shape, or a combination thereof.

[0045] This embodiment significantly enhances the stability and friction of the guardrail by designing the limiting part to be one or a combination of a columnar, conical, barbed, or truncated cone shape: limiting parts of different shapes can adapt to different ground conditions and provide stronger anti-overturning capabilities.

[0046] Optionally, the anti-slip limiter 22 further includes a limit support portion 222 connected to the limit portion 221 , and the limit support portion 222 and the limit portion 221 are respectively located on two sides of the support base plate 11 .

[0047] In this embodiment, the limiting support portion 22 can provide additional supporting force on the other side of the supporting base plate, ensuring that the limiting portion 21 effectively contacts the ground and enhances the stability and anti-overturning ability of the guardrail. This design not only optimizes the friction distribution and prevents the guardrail from shifting due to uneven external force, but also can adapt to different ground conditions and improve the performance of the guardrail in complex environments.

[0048] In actual applications, the structure of the limit support part 22 can be designed to be adjustable so as to adjust the support force and friction force distribution according to the actual usage scenario. By designing an adjustable limit support part, the user can flexibly adjust the height and angle of the support part according to the friction characteristics of different ground surfaces and usage requirements to achieve the best friction effect.

[0049] Optionally, the two support rods 33 are equidistantly arranged on both sides of the limiting portion 221, which effectively enhances the stability and bearing capacity of the limiting portion 221. The equidistant arrangement of the support rods 33 ensures uniform force on the limiting portion 221 and avoids displacement or deformation caused by uneven stress.

[0050] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
