Description

Technical Field

[0001] This utility model relates to a high impact-resistant straight-line crash barrier, belonging to the technical field of straight-line crash barriers. Background Technology

[0002] A straight-line crash barrier is a common road safety facility. Its design features a straight, linear shape and a simple yet robust structure. It is primarily used to separate and protect areas such as driveways and pedestrian walkways. These barriers are typically made of high-strength metal materials, effectively absorbing and dispersing the impact of vehicle collisions, thereby reducing injury to vehicles and passengers in the event of an accident.

[0003] Authorization notice number (CN213837432U) discloses a crash barrier, including a crossbeam connected to at least two sets of barrier supports by fasteners; each barrier support comprises a rectangular steel plate and a connector on one side. A modular structure is adopted, with each module consisting of a welded barrier support and a crossbeam. The barrier supports are fastened to the crossbeam with bolts. Each assembled module is installed on a concrete surface using expansion bolts. It has sufficient strength to prevent forklift collisions with factory buildings, is easy to install, and can be disassembled and reused.

[0004] However, when the aforementioned technologies collide with a vehicle, the impact force will be directly transmitted to the guardrail and the vehicle itself, which may cause the guardrail to deform or break, and cause greater injury to the vehicle and passengers. Furthermore, due to the lack of a buffer structure during a collision, the guardrail will lose its function of absorbing and dispersing the impact force, increasing the severity of the accident, and may not be able to effectively prevent vehicles from entering the oncoming lane or running off the road, increasing the risk of secondary accidents.

[0005] Therefore, a high-impact-resistant straight-line guardrail is proposed. Utility Model Content

[0029] Example 1

[0030] like Figure 1-5As shown, this utility model embodiment provides a high impact-resistant straight-line crash barrier, including a support post 1 and a straight-line guardrail 2. There are two support posts 1, which are symmetrically arranged. The straight-line guardrail 2 is located in front of the two support posts 1. A buffer mechanism 3 is provided on the inner side of each of the two support posts 1. The buffer mechanism 3 includes a first guide rod 301, a first sliding sleeve 302, a first rigid spring 303, a guide block 304, a fixing rod 305, a through hole 306, and a mounting plate 307. The first guide rod 301 is fixedly installed on the top of the support post 1, the first sliding sleeve 302 is slidably connected to the surface of the first guide rod 301, and the first rigid spring 303 is fixedly installed on the top of the support post 1. A guide block 304 is fixedly connected to the left and right sides of the first sliding sleeve 302. A fixing rod 305 is fixedly connected to the front side of the guide block 304. A through hole 306 is opened on the left and right sides of the front side of the support column 1. The fixing rod 305 passes through the through hole 306 and extends to the front side of the support column 1. A mounting plate 307 is fixedly connected to the front end of the fixing rod 305. The straight guardrail 2 is fixedly connected to the surface of the mounting plate 307 by bolts. A tension spring 308 is fixedly installed on the front side of the guide block 304. The fixing rod 305 is located at the tension spring. Inside the support column 1, the other end of the tension spring 308 is fixedly connected to the inner cavity of the support column 1. A first connecting block 309 is fixedly installed at the bottom of the first sliding sleeve 302. A first connecting rod 310 is movably connected to the inner side of the first connecting block 309. A second guide rod 311 is fixedly installed in the inner cavity of the support column 1. A second sliding sleeve 312 is slidably connected to the surface of the second guide rod 311. A second connecting block 314 is fixedly installed at the front of the second sliding sleeve 312. A pin 315 is movably connected to the inner side of the second connecting block 314. The lower end of the first connecting rod 310 is movably connected to the inner side of the second connecting block 314 via the pin 315. The second guide rod 310... A second rigid spring 313 is fixedly installed on the surface of 11. The upper end of the second rigid spring 313 is fixedly connected to the bottom of the second sliding sleeve 312. The left and right sides of the surface of the pin 315 are movably connected to the second connecting rod 316. The inner cavity of the support column 1 is fixedly installed with a third guide rod 317. The surface of the third guide rod 317 is slidably connected to the third sliding sleeve 318. The lower end of the second connecting rod 316 is movably connected to the left and right sides of the surface of the third sliding sleeve 318 through a rotating shaft. A third rigid spring 319 is fixedly installed on the front side of the surface of the third guide rod 317. The rear end of the third rigid spring 319 is fixedly connected to the front side of the surface of the third sliding sleeve 318.

[0031] By setting up the buffer mechanism 3, the impact force of the collision can be effectively absorbed and dispersed when a vehicle collides with the guardrail 2, thereby reducing the damage to the vehicle and passengers, improving the safety of traffic accidents, reducing the risk of guardrail deformation or breakage, extending its service life, and reducing the frequency of maintenance and replacement. In addition, it can better prevent vehicles from crossing the guardrail into the opposite lane or running off the road, further improving the overall safety of the road.

[0032] Example 2

[0033] In one embodiment, guide grooves 4 are provided on both the left and right sides of the inner cavity of the support column 1, and guide blocks 304 are slidably connected to the inner side of the guide grooves 4. A base 5 is fixedly installed at the bottom of the support column 1, and foot supports 6 are fixedly installed on both the front and rear sides of the top of the base 5. Diagonal supports 7 are fixedly installed on both the left and right sides of the top of the base 5. Both foot supports 6 and diagonal supports 7 are fixedly connected to the surface of the support column 1.

[0034] The guide groove 4 serves as a guide, preventing the first sliding sleeve 302 and the guide block 304 from shifting during movement. The foot brace 6 and the diagonal brace 7 provide support for the support column 1, thereby increasing the lateral support force around the support column 1.

[0035] In operation, this utility model works as follows: After the support column 1 is fixed to the installation position with bolts, the straight guardrail 2 is installed on the surface of the mounting plate 307 for protection. When the straight guardrail 2 is impacted, it will cause the mounting plate 307 to move towards the support column 1. As the mounting plate 307 moves, it will also cause the through hole 306 and the fixing rod 305 to move backward, so that the guide block 304 and the first sliding sleeve 302 move backward along the inner side of the guide groove 4, compressing the first hard spring 303 and absorbing and eliminating the impact force. As the first sliding sleeve 302 moves, it will also cause the upper end of the first connecting block 309 and the first connecting rod 310 to move. As the connecting rod 310 moves, it will deflect. The lower end connected to the second connecting block 314 will drive the second connecting block 314 and the second sliding sleeve 312 to move downward. As the second sliding sleeve 312 moves, it will squeeze the second hard spring 313, thereby absorbing and eliminating the impact force again. As the second connecting block 314 moves, it will drive the pin 315 and the upper end of the second connecting rod 316 to move downward, causing the lower end of the second connecting rod 316 to deflect. This will drive the third sliding sleeve 318 to move forward along the surface of the third guide rod 317, squeezing the third hard spring 319, which will absorb the impact force again.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
