Description

Technical Field

[0001] The present application relates to the technical field of road facilities, and in particular to a quick-release guardrail assembly. Background Art

[0002] With the rapid development of highway construction and the continuous increase in traffic volume, the performance and reliability of guardrails as important safety facilities on highways have received widespread attention. As the core part of the guardrail system, the design and performance of guardrail components directly determine the overall effectiveness of the guardrail.

[0003] At present, traditional guardrail components are usually made of steel and fixed to the road surface by welding or bolting. Although this type of guardrail component can meet the safety requirements of highways to a certain extent, there are still some problems in actual use. First of all, there are many inconveniences in the installation and disassembly process of traditional guardrail components, especially in emergency situations, such as traffic accident handling, road maintenance, etc., when the guardrail needs to be quickly replaced or moved, the disassembly and installation efficiency of traditional guardrails is particularly low. As a result, rescue and repair work takes a long time, affects the rapid restoration of road traffic, and easily damages the guardrail. Secondly, the adaptability of traditional guardrail components is poor, and it is difficult to adapt to the needs of different road sections and traffic flows. In addition, with the increase in traffic flow and the improvement of vehicle performance, the requirements for the impact resistance of guardrail components are also getting higher and higher. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a quick-release guardrail assembly to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0006] A quick-release guardrail assembly comprises a guardrail plate, wherein support mechanisms are installed at both ends of the back side of the guardrail plate, wherein the support mechanisms comprise two plugs, two support columns, two locking components and two fixing components, wherein two of the plugs are respectively welded to both ends of the back side of the guardrail plate, and the side walls of the two support columns are respectively fitted to the two ends of the back side of the guardrail plate and are fixedly connected to the two plugs, the two locking components are respectively installed inside the two support columns and are plugged into the two plugs, and the inner walls of the two fixing components are respectively connected to the bottom end bolts of the two support columns.

[0007] Furthermore, the plug-in component includes two L-shaped blocks, two plug-in interfaces and two through holes. One end of the two L-shaped blocks are respectively fixedly connected to the two ends of the back side of the guardrail plate, and the other end is respectively plugged into the inside of the two plug-in interfaces. The side walls of the two support columns are respectively provided with two of the plug-in interfaces, and the surfaces of the two L-shaped blocks are respectively provided with two of the through holes, and the inner walls of the through holes are in contact with the outer walls of the locking component.

[0008] Furthermore, two connecting blocks are welded on one side of the support column and fit with the back side of the guardrail plate, and the opposite ends of the two connecting blocks are fit with both sides of the guardrail plate.

[0009] Furthermore, the locking piece includes a T-shaped plug-in hole, a T-shaped plug-in column, an internal thread, an external thread and a hexagonal hole. The T-shaped plug-in hole is opened inside the support column, the internal thread is opened at the top of the T-shaped plug-in hole, the external thread is opened at the top of the T-shaped plug-in column, and the hexagonal hole is opened at the top. The outer wall is tightly fitted with the T-shaped plug-in hole and the inner wall of the through hole, and the internal thread is threadedly connected with the external thread.

[0010] Furthermore, the fixing device includes a base, two clamping blocks, two holes, two fixing bolts, two nuts and a number of ground nails. The two sides of the base surface are respectively welded to the bottom ends of the two clamping blocks, and the inner wall is clamped with the bottom end of the support column. The side wall of the support column is provided with two holes and fits with the opposite ends of the two clamping blocks. The bottom ends of the two fixing bolts respectively penetrate the two clamping blocks and the two holes and are threadedly connected to the inner circles of the two nuts. The bottom ends of the several ground nails are evenly spaced through the base surface and inserted into the road.

[0011] Furthermore, four mounting holes are provided at both ends of the guardrail plate, and the two ends of the back side are respectively integrally formed with the two L-shaped blocks.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model adopts a modular design and consists of multiple parts, making installation and disassembly extremely convenient. The two support columns are quickly connected to the guardrail plate through the plug-in parts and reinforced by the locking parts. No special tools are required, which greatly improves the construction efficiency. This design is particularly suitable for sections such as highways where guardrails need to be frequently replaced or repaired, and can significantly reduce construction time and labor costs.

[0014] 2. The utility model has high stability and safety. The support column and the insert are tightly connected by plugging and clamping, which ensures the overall stability of the guardrail. At the same time, the design of the locking piece further enhances the firmness of the connection, preventing the guardrail plate from loosening or falling off when impacted. In addition, the fixing piece firmly fixes the support column to the road surface through the clamp block and the fixing bolt, and inserts the ground nail into the road to increase stability, effectively preventing the guardrail from being displaced or overturned by the impact of the vehicle.

[0015] 3. The utility model also has good versatility and interchangeability.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] Example:

[0029] See also Figure 1 , Figure 5 , Figure 6 A quick-release guardrail assembly includes a guardrail plate 1. Four mounting holes 11 are provided at both ends of the guardrail plate 1, and the guardrail plate 1 is integrally formed with two L-shaped blocks 211.

[0030] The guardrail plate 1 achieves convenient installation, efficient connection, excellent impact resistance and beautiful appearance by providing mounting holes 11, adopting a wavy design and being integrally formed with the L-shaped block 211. Multiple guardrail plates 1 can be tightly connected together through these mounting holes 11 to form a continuous and stable protective barrier.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8A quick-release guardrail assembly includes a support mechanism 2 installed at both ends of the back side of a guardrail plate 1, the support mechanism 2 includes two plug-ins 21, two support columns 22, two locking components 23 and two fixing components 24, wherein the plug-in component 21 includes two L-shaped blocks 211, two plug interfaces 212 and two through holes 213; two connecting blocks 221 are welded on one side of the support column 22; the locking component 23 includes a T-shaped plug-in hole 231, a T-shaped plug-in column 232, an internal thread 233, an external thread 234 and a hexagonal hole 235; the fixing component 24 includes a base 241, two clamping blocks 242, two holes 243, two fixing bolts 244, two nuts 245 and a plurality of ground nails 246.

[0032] Among them, the plug 21 ensures a stable connection between the guardrail plate 1 and the support column 22. The design of the plug 21 takes into account both the stability of the connection and the convenience of installation, providing strong technical support for the quick-disassembly guardrail plate 1. One end of the two L-shaped blocks 211 is fixedly connected to the two ends of the back of the guardrail plate 1, which means that the L-shaped block 211 and the guardrail plate 1 form a whole, and jointly bear the impact and pressure from the outside. The other end of the L-shaped block 211 is inserted into the two plug interfaces 212, which are provided on the side walls of the support column 22, so that the L-shaped block 211 and the support column 22 are tightly connected together. In addition, two through holes 213 are provided on the surface of the L-shaped block 211. The two through holes 213 not only provide installation space for the locking piece 23, but also enable the outer wall of the locking piece 23 to fit tightly on the inner wall of the through hole 213. When the locking piece 23 is inserted into the through hole 213 and fixed by means of threads or the like, a stable connection structure is formed among the L-shaped block 211, the support column 22 and the locking piece 23, further enhancing the overall stability of the guardrail assembly.

[0033] Among them, the support column 22 not only provides the main support force of the guardrail assembly, but also ensures the stability of the entire structure. In order to further optimize the connection between the support column 22 and the guardrail board 1, two connecting blocks 221 are welded on one side of the support column 22. The two connecting blocks 221 fit tightly with the two sides of the guardrail board 1, thereby increasing the contact area between the support column 22 and the guardrail board 1 and improving the overall stability. The guardrail board 1 is supported and fixed from multiple directions.

[0034] Among them, the locking piece 23 is a key component for quickly and firmly connecting the support column 22 and the L-shaped block 211. A T-shaped plug hole 231 is provided inside the support column 22. The design of this hole allows the insertion of the T-shaped plug column 232. The outer top of the T-shaped plug column 232 is provided with an external thread 234, which can be threadedly connected with the internal thread 233 at the top of the T-shaped plug hole 231. This design not only increases the stability of the connection, but also enables the locking piece 23 to be firmly fixed inside the support column 22 and is not easy to loosen. In addition, a hexagonal hole 235 is also provided at the top of the T-shaped plug column 232. The design of this hole facilitates the use of tools such as a hexagonal wrench for rotation, making the installation and removal of the locking piece 23 simple and efficient. At the same time, the outer wall of the T-shaped plug column 232 is tightly fitted with the inner wall of the T-shaped plug hole 231 and the through hole 213. This tight fit further enhances the stability and reliability of the connection.

[0035] Among them, the role of the fixing member 24 is crucial. It is responsible for firmly fixing the support column 22 on the road surface to ensure the stability and safety of the entire guardrail assembly. The base 241 is the main part of the fixing member 24, and the two sides of its surface are welded together with the bottom ends of the two clamping blocks 242. This design enables the clamping block 242 to be firmly fixed on the base 241 and form a clamping relationship with the bottom end of the support column 22. Two holes 243 are opened on the side wall of the support column 22, and the two holes 243 are tightly fitted with the opposite ends of the clamping block 242. During the installation process, the bottom ends of the two fixing bolts 244 penetrate the two clamping blocks 242 and the two holes 243 respectively, and are threadedly connected with the inner rings of the two nuts 245. This connection method is not only simple and easy to operate, but also can effectively fix the clamping block 242 and the support column 22 to prevent them from loosening or displacement during use. In addition, the fixing member 24 also includes a plurality of ground nails 246, the bottom ends of which penetrate the surface of the base 241 at equal intervals and are inserted into the road. The design of the ground spikes 246 enables the fixing member 24 to be firmly fixed to the road surface, and even in adverse weather conditions or when a traffic accident occurs, the fixing member 24 can maintain its stability and prevent the guardrail assembly from being pulled up or displaced.

[0036] The working principle of the quick-release guardrail assembly is as follows: when the guardrail needs to be installed, the L-shaped block 211 only needs to be inserted into the plug-in port 212 of the support column 22, and the T-shaped plug-in column 232 is threadedly connected to the T-shaped plug-in hole 231 and the internal thread 233 inside the support column 22 through the external thread 234 to achieve fixation. At the same time, the outer wall of the T-shaped plug-in column 232 is tightly fitted with the inner wall of the through hole 213 and the T-shaped plug-in hole 231 to ensure the stability and sealing of the connection. Then, the base 241 is clamped with the bottom end of the support column 22 through the clamp block 242, and is fastened by the fixing bolt 244 and the nut 245. In addition, the ground nail 246 is inserted into the road to provide additional stability for the entire guardrail assembly. The whole process is simple and quick, and no complicated tools or equipment are required. When the guardrail needs to be disassembled, the components can be separated by simply loosening the locking piece 23 and the fixing piece 24. This design makes the disassembly of the guardrail assembly also convenient and efficient, and is convenient for replacement or movement when necessary.

[0037] It should be noted that the specific model specifications of the T-shaped plug-in column 232 and the ground nail 246 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
