Description

Technical Field

[0001] This utility model belongs to the technical field of highway guardrail equipment, and in particular relates to a variable-angle outward-extending guardrail. Background Technology

[0002] Drainage ditches are typically installed on both sides of highways. One side of the ditch is usually a mountain or obstacle, while the other side is the highway surface. To protect the front side, guardrails are currently installed across the ditch or obstacle to guide traffic to the road side. To prevent vehicles from crashing directly into the ditch section guardrail in the event of an accident, the guardrails are currently installed at an angle. This means that the entire section of the guardrail extends at an angle from the road side to the other side of the drainage ditch. The current regulations for ditch guardrails specify an inclination rate of 1:11, 1:14, or 1:17, so the angle between the ditch guardrail and the road guardrail can be considered fixed.

[0003] In reality, when considering car collisions, the most common occurrences are on one side of the road. The larger the angle between the ditch-crossing guardrail and the road guardrail, the more dangerous the collision and the greater the damage. To reduce the damage to cars from the guardrail during a collision, the angle between the inclined ditch-crossing guardrail and the road guardrail should be as gentle as possible. However, this is currently limited by regulations on the slope of the entire ditch-crossing guardrail section, so no further adjustments can be made. Utility Model Content

[0004] The purpose of this utility model is to provide a variable-angle outward-extending guardrail, which adds a transition guardrail between the roadside guardrail and the crossing guardrail. This allows the crossing guardrail to meet design specifications while the transition guardrail makes the overall angle more gradual, meeting usage requirements and greatly improving safety performance.

[0005] Based on this, the present invention provides a variable-angle outward-extending guardrail, including a guardrail body and multiple mounting brackets connected to the guardrail body;

[0006] The guardrail body includes a roadside guardrail, a transition guardrail, and a crossing guardrail connected in sequence. The mounting bracket includes a first bracket, an adjusting bracket, and a connecting bracket. The roadside guardrail is installed on the side of the ditch closest to the road surface via the first bracket. The crossing guardrail is installed at an angle above the ditch via the connecting bracket and crosses from the side of the ditch closest to the road surface to the other side.

[0007] The adjusting bracket has a first connecting arm and an adjusting connecting arm with an adjustable extension length. The first end of the transition guardrail is connected to the end of the roadside guardrail or the first bracket. The end of the transition guardrail is connected to the first connecting arm. The adjusting connecting arm is connected to the first end of the crossing guardrail. The angle between the crossing guardrail and the transition guardrail can be adjusted by changing the extension length of the adjusting connecting arm.

[0008] As described above, in a variable-angle outward-extending guardrail, the adjusting bracket further includes a mounting column, one end of the first connecting arm and the adjusting connecting arm are both connected to the mounting column, and the first connecting arm and the adjusting connecting arm are installed in a V-shape.

[0009] As described above, in a variable-angle outward-extending guardrail, the first connecting arm includes an outward-extending arm and a first connecting portion disposed at the end of the outward-extending arm, the first connecting portion being used to connect to the end of the transition guardrail.

[0010] The adjustable connecting arm includes a fixed arm and an extendable arm movably connected to the fixed arm. The outward-facing end of the extendable arm is provided with a second connecting part. The extendable arm is used to connect to the first end of the guardrail.

[0011] As described above, in a variable-angle outward-extending guardrail, the fixed arm is sleeved on the extended arm, and the end of the fixed arm is also provided with a locking structure for locking the extended arm.

[0012] As described above, in a variable-angle outward-extending guardrail, the locking structure includes multiple connecting holes on the end of the fixed arm, the extension arm is located inside the fixed arm, and the extension arm is provided with multiple mating holes corresponding to the connecting holes. The locking structure also includes a connector that can pass through the connecting holes and the mating holes to lock the extension arm onto the fixed arm.

[0013] As described above, in a variable-angle outward-extending guardrail, the mounting post is installed on one side of the ditch, and the transition guardrail is installed on the side of the ditch near the road or above the ditch via a first connecting arm and an adjusting connecting arm.

[0014] As described above, in a variable-angle outward-extending guardrail, the end of the transition guardrail and the beginning of the crossing guardrail are further provided with a docking structure.

[0015] As described above, in a variable-angle outward-extending guardrail, the first support has multiple components, which are spaced apart along the length of the roadside guardrail. The first support includes a first post and a roadside guardrail connecting part disposed on the first post.

[0016] As described above, a variable-angle outward-extending guardrail has multiple connecting brackets that are spaced apart along the length of the guardrail. Each connecting bracket includes a cantilever and a second column connected to the cantilever. The second columns are all installed on one side of the ditch and connected to the guardrail spanning the ditch via the cantilever.

[0017] Implementing the embodiments of this utility model has the following beneficial effects:

[0018] This utility model provides a variable-angle outward-extending guardrail. By modifying the traditional guardrail body into a three-section design, a transition guardrail is added between the roadside guardrail and the crossing guardrail. In addition, the two connecting arms of the adjustable bracket are connected to the transition guardrail and the crossing guardrail respectively. By adjusting the connecting arms, the angle of the crossing guardrail can be adjusted to maintain a standard slope.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model embodiment provides a variable-angle outward-extending guardrail, characterized in that it includes a guardrail body and multiple mounting brackets connected to the guardrail body; the guardrail body is connected to both sides of the ditch 92 through multiple mounting brackets.

[0026] Specifically, the guardrail body includes a roadside guardrail 11, a transition guardrail 12, and a crossing guardrail 13 connected in sequence. The mounting bracket includes a first bracket 2, an adjusting bracket 3, and a connecting bracket 4. The roadside guardrail 11 is installed on the side of the ditch 92 closest to the road surface via the first bracket 2. The crossing guardrail 13 is installed obliquely above the ditch 92 via the connecting bracket 4, and crosses from the side of the ditch 92 closest to the road surface to the other side. The adjusting bracket 3 has a first connecting arm 31 and an adjusting connecting arm 32 with an adjustable extension length. The first end of the transition guardrail 12 is connected to the end of the roadside guardrail 11 or the first bracket 2. The end of the transition guardrail 12 is connected to the first connecting arm 31. The adjusting connecting arm 32 is connected to the first end of the crossing guardrail 13. The angle between the crossing guardrail 13 and the transition guardrail 12 can be adjusted by changing the extension length of the adjusting connecting arm 32. By modifying the traditional guardrail body into a three-section design, a transition guardrail is added between the roadside guardrail and the crossing guardrail. In addition, the two connecting arms of the adjustable bracket are connected to the transition guardrail and the crossing guardrail respectively. The angle of the crossing guardrail is adjusted by adjusting the connecting arms to maintain a standard slope, while the transition guardrail makes the angle between the roadside guardrail and the crossing guardrail more gradual. After adjusting and reducing the angle, it can provide better protection for colliding vehicles and reduce the injury to drivers and passengers.

[0027] Compared to traditional connection methods, which involve a direct bend from the roadside guardrail to a crossing guardrail with a specified slope of 1:17, resulting in an angle of approximately 8° between the crossing guardrail and the roadside guardrail, this solution, by adding a transition guardrail, allows for an angle of 5° between the transition guardrail and the roadside guardrail (e.g., ...). Figure 1 (The included angle 'a') and then the angle between the transition guardrail and the crossing guardrail is 3° (e.g., ... Figure 1 The angle between the guardrail and the road guardrail is set at 8 degrees (b), thus ultimately meeting the requirement that the angle between the road guardrail and the guardrail is 8 degrees. The transition guardrail makes the angle between the road guardrail and the guardrail more gradual.

[0028] In addition, the length of the transition guardrail can be set according to the requirements of the crossing guardrail to change the docking position between the transition guardrail and the crossing guardrail. Specifically, as mentioned above, in actual use, since the car is located on one side of the road guardrail, in the event of an accident, taking the side of the car scraping the guardrail as an example, the greatest chance is to scrape the guardrail near the side of the ditch 92. Therefore, this solution tries to shift the crossing guardrail to the other side of the ditch through the transition guardrail, so that the transition guardrail becomes the part most likely to be scraped. Since the angle between the transition guardrail and the road guardrail is small, the car is easily guided to the direction of the road guardrail, thereby greatly reducing the damage to the accident vehicle.

[0029] In this embodiment of the invention, the adjusting bracket 3 further includes a mounting column 33. One end of the first connecting arm 31 and the adjusting connecting arm 32 are both connected to the mounting column 33, and the first connecting arm 31 and the adjusting connecting arm 32 are installed in a V-shape. This allows the two connecting arms to connect to two guardrails respectively. Moreover, the adjusting connecting arm 32 can be adjusted to the corresponding length according to the requirements of crossing the guardrail 13, so as to meet the slope setting of crossing the guardrail 13.

[0030] In addition, to reinforce the connection, this solution includes a docking structure at the end of the transition guardrail 12 that connects to the beginning of the crossing guardrail 13. In this solution, the docking structure consists of multiple mounting holes arranged vertically along the transition guardrail 12 and the crossing guardrail 13. The end of the transition guardrail 12 and the beginning of the crossing guardrail 13 are docked using screws, bolts, or other connecting components.

[0031] In a specific embodiment of this utility model, the first connecting arm 31 has the following structure: the first connecting arm 31 includes an outward arm 311 and a first connecting part 312 disposed at the end of the outward arm 311. The first connecting part 312 is used to connect to the end of the transition guardrail 12. In this solution, the outward arm 311 has a fixed length and is mainly used to fix the end of the transition guardrail 12.

[0032] The specific structure of the adjusting connecting arm 32 is as follows: the adjusting connecting arm 32 includes a fixed arm 321 and an extendable arm 322 movably connected to the fixed arm 321. The outward-facing end of the extendable arm 322 is provided with a second connecting part 323. The extendable arm 322 is used to connect with the first end of the crossing guardrail 13. This solution adjusts the position of the first end of the crossing guardrail 13 by adjusting the length of the extendable arm 322, thereby allowing adjustment of the corresponding slope according to design requirements.

[0033] Specifically, in this solution, the fixed arm 321 is sleeved on the extension arm 322, and the end of the fixed arm 321 is also provided with a locking structure for locking the extension arm 322. The length of the extension arm 322 is changed through a telescopic sleeve connection, and after the length is adjusted, it is locked by the locking structure. This simple structure is convenient to use. More specifically, the locking structure of this solution includes multiple connecting holes 3210 on the end of the fixed arm 321. The extension arm 322 is located inside the fixed arm 321, and the extension arm 322 has multiple mating holes corresponding to the connecting holes 3210. The locking structure also includes a connector that can pass through the connecting holes 3210 and the mating holes to lock the extension arm 322 onto the fixed arm 321. The connectors can be screws, bolts, etc., and multiple connection holes 3210 can be set in multiple levels. The positions of the connection holes 3210 can be preset according to multiple slope standards. During adjustment, the corresponding connection hole can be directly selected for locking according to requirements, making it more convenient and efficient to use.

[0034] In this design, to increase the strength of the transition guardrail 12, the mounting post 33 is installed on one side of the ditch 92, and the transition guardrail 12 is installed on the side of the ditch 92 near the roadside or above the ditch 92 via the first connecting arm 31 and the adjusting connecting arm 32. Furthermore, there are multiple first supports 2, spaced apart along the length of the roadside guardrail 11. Each first support 2 includes a first post 21 and a roadside guardrail connecting part 22 mounted on the first post 21. There are multiple connecting supports 4, spaced apart along the length of the crossing guardrail 13. Each connecting support 4 includes a cantilever 41 and a second post 42 connected to the cantilever 41. The second posts 42 are all installed on one side of the ditch 92 and connected to the crossing guardrail 13 spanning above the ditch 92 via the cantilever 41. The first bracket 2 is directly installed on one side of the road surface, and its function is to fix the road guardrail extending along the road surface. However, this solution, through optimized design, installs the brackets for the transition guardrail 12 and the crossing guardrail 13, namely the adjusting bracket 3 and the connecting bracket 4, on the other side of the ditch. This eliminates the adverse effects of the guardrail on traffic in the road fill and cut sections, and ensures that even the transition guardrail 12 and the crossing guardrail 13, which cross the ditch, have connection and support. This greatly improves the overall strength of the guardrail body, solves the defects of the existing guardrail production and installation being restricted by the drainage ditch, reduces installation costs, improves installation efficiency, and ensures the protective quality of the extended guardrail.

[0035] In this embodiment of the utility model, the installation takes into full account the terrain. The cantilever frame 41 is installed as a whole on one side of the obstacle for easy fixation. Specifically, the cantilever frame 41 is a V-shaped frame. The function of the large-span V-shaped guardrail structure is to solve the defects of existing guardrail production and installation being restricted by drainage ditches, simplify the on-site installation process of the extended guardrail, reduce the number of customized components, reduce installation costs, improve installation efficiency, and ensure the protective quality of the extended guardrail.

[0036] This utility model provides a variable-angle outward-extending guardrail. By modifying the traditional guardrail body into a three-section design, a transition guardrail is added between the roadside guardrail and the crossing guardrail. In addition, the two connecting arms of the adjustable bracket are connected to the transition guardrail and the crossing guardrail respectively. By adjusting the connecting arms, the angle of the crossing guardrail can be adjusted to maintain a standard slope. The transition guardrail makes the angle between the roadside guardrail and the crossing guardrail more gradual. After adjusting and reducing the angle, it can provide better protection for colliding vehicles and reduce the injury to drivers and passengers.
