River-spanning bridge entrance ramp height limitation frame

Abstract

The invention relates to the technical field of traffic safety, in particular to a river-spanning bridge entrance ramp height limitation frame. The frame comprises a lifting-adjustable height limitation protective frame arranged at the ramp entrance and a lifting-adjustable height limitation warning frame provided with reflective film, the height limitation protective frame and the height limitation warning frame are arranged at a distance, and the height limitation warning frame is arranged in front of the height limitation protective shelf, a height limitation sign and a variable informationboard are arranged on the upper portion of the height limitation warning frame, a height-adjustable height limitation warning frame height limitation bar is arranged on the lower portion of the height limitation warning frame, an anti-collision barrel is arranged in front of a height limitation protective frame vertical rod of the height limitation protective frame, an anti-collision barrel and awarning column are arranged in front of a height limitation warning frame vertical rod of the height limitation warning frame. By means of the height limitation warning frame provided with the reflective film, the height limitation sign and the variable information board, the good warning performance is achieved, drivers can pay more attention to the height limitation information; by means of theanti-collision barrel and the warning column which are arranged in front of the height limitation warning frame vertical rod of the height limitation warning frame, the phenomenon that vehicles directly impact the height limitation warning frame vertical rod can be avoided, and the certain sight guiding effect is achieved.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an elevated limit bridge at the entrance ramp of a cross-river bridge. Background technique [0002] In order to ensure the traffic safety of special roads such as overpasses, viaducts, bridges, and tunnels, relevant departments have issued measures to prohibit super-high vehicles or large vehicles from driving on the above special road sections. Elevated, restricting the passage of super-high vehicles or large vehicles, so as to ensure the traffic safety of the above special roads. [0003] However, the current design of the height-limiting road is not perfect. The setting of the height-limiting road on the elevated or high-grade road does not meet the driver's expectations. Collisions between super-high or large vehicles and the height-limiting road happen from time to time, which seriously threatens the drivers, passengers, and vehicles. and traffic safety on special r...

AI Technical Summary

Problems solved by technology

Due to the lack of a good line of sight guidance and warning function, the drivers of large vehicles are not easy to pay attention to the height limit or misjudge the height limit of the height limit. The above reasons have induced vehicles to hit the height limit at the entrance of the cross-river bridge entrance ramp. In the occurrence of traffic accidents, there is an urgent need for a safe and effective overpass for the entrance ramp of cross-river bridges.
