Description

A kind of guardrail for urban highway traffic

Technical Field

The utility model relates to the technical field of urban road protection, in particular to a protection fence for urban highway traffic.

Background Art

Traffic guardrails are traffic safety facilities installed on the outside of roadsides, traffic dividers, and sidewalk curbs. They absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from going off the road or entering the opposite lane, and minimizing injuries to occupants.

Most of the existing guardrails are fixed by welding. If they need to be moved to other places, they will be too large and too long to be moved, or the number of workers will be increased. Increasing the number of workers will also increase the labor cost.

When maintenance, replacement or adjustment is required, the protective tube can be easily disassembled by simply taking out the protective tube.

Preferably, a second spring is arranged at the bottom of the lower notch, and a support plate is installed at the top end of the second spring.

Through the above technical solution, the lower groove and the second spring make it very convenient to install the protective tube. Only the protective tube needs to be pressed downward, and the second spring will be compressed due to the pressure, so that the protective tube can be smoothly installed on the second cross tube. Due to the characteristics of the second spring, once the protective tube is installed, the spring will rebound to provide a better fit, ensuring that the protective tube is firmly fixed on the second cross tube and is not easy to loosen or fall off.

Preferably, the spring block installed in the upper slot cooperates with the support plate installed in the lower slot.

Through the above technical solution, by cooperating with the spring block installed in the upper slot and the support plate installed in the lower slot, it is only necessary to press the protective tube downward, insert the top end of the protective tube into the inner wall of the upper slot, and insert the bottom end into the lower slot. The spring will be compressed due to the pressure, so that the protective tube can be smoothly installed on the cross tube. The rebound force of the spring can make the protective tube fit tightly with the first cross tube and the second cross tube, ensuring that the protective tube is firmly fixed on the cross tube.

Preferably, the first threaded rod and the second threaded rod are installed at two ends of the first transverse tube and the second transverse tube, and the first threaded rod and the second threaded rod are slidably connected to the inner wall of the second sliding groove.

Through the above technical solution, the height of the first cross tube and the second cross tube can be easily adjusted through the combination of the threaded rod and the slide groove, and can be flexibly adjusted as needed to adapt to different roads or traffic requirements. The installation and adjustment of the height of the guardrail becomes easier, and the height of the first cross tube and the second cross tube can be easily fine-tuned by rotating the nut.

Preferably, a threaded hole is provided on the upper surface of the base, and a plurality of threaded holes are provided, respectively located at four corners of the upper surface of the base.

Through the above technical solution, the base is firmly connected to the ground, which can improve the stability of the entire protection system and reduce the displacement and tilt of the guardrail in the event of a collision, thereby more effectively preventing vehicles from rushing into or passing through the guardrail. By installing the base on the ground to connect the guardrail, a safer traffic environment can be provided, the risk of accidents can be reduced, and the damage caused by accidents can be mitigated.

Compared with the prior art, the utility model provides a guardrail for urban highway traffic, which has the following beneficial effects:
