Description

Technical Field

[0001] The utility model relates to the field of road guardrail anti-collision, in particular to an anti-collision end device for a road guardrail. Background Art

[0002] The triangular ends of exit ramps on expressways and first-class highways are often accident-prone locations. Because most corrugated guardrails are untreated, serious traffic accidents often occur. With the continuous improvement of transportation infrastructure in recent years, nearly all end-of-ramps have been treated. These treatments prevent contact between the guardrail tip and the vehicle, preventing serious damage from the guardrail penetrating the vehicle. They also absorb energy, increase the duration of force, and provide a positive deflection for the colliding vehicle, minimizing subsequent damage.

[0003] The existing end structure is relatively simple, the anti-collision ability is not ideal, and the vehicle cannot play a buffering role when colliding with the end, which will still cause great damage. Utility Model Content

[0012] The beneficial effects of the utility model are:

[0013] 1. The device is installed on the ground through the mounting base, and the mounting column is connected to the mounting base to fix the mounting column to the ground. The connecting column drives the connecting frame to adjust the direction to prevent the connecting frame from being misaligned due to the rotation of the mounting column. The cover blocks the rainwater on the outside to avoid rust caused by water accumulation inside the connecting column. The combined design makes the use of the mounting base and the mounting column more flexible.

[0014] 2. The device connects the fixing hole and the long guardrail through a fixing bolt, so that the end mounting plate is fixed to the end of the long guardrail, thereby installing the end, connecting the first screw hole and the second screw hole through a bolt, and installing the mounting frame on the end mounting plate, so that the protective end is tightly fixed on the end mounting plate, and the end mounting plate is fixed to the outermost side of the guardrail.

[0015] 3. The device uses the first buffer spring to buffer the protective end when it is hit from the outside, and the second buffer spring to buffer the protective end when it is hit from the front, so that the protective effect of the protective end is further improved. The spring tube and the spring mouth fix the first buffer spring and the second buffer spring to prevent them from tilting when they are hit.

[0016] In summary, the device can reduce the damage caused to both sides by an object hitting the protective end through the protective pad, and further improve the protective effect of the protective end through the buffer spring. BRIEF DESCRIPTION OF THE DRAWINGS
