Description

Technical Field

[0001] This utility model relates to the technical field of traffic facilities, and in particular to a height-limiting traffic device. Background Technology

[0002] Height restriction barriers can prevent oversized vehicles from colliding with traffic facilities such as bridges, tunnels, and culverts, avoiding structural damage caused by collisions and extending their service life. They can also protect overhead cables, pipelines, and other facilities from being scratched by oversized vehicles. At the same time, they guide vehicles to travel according to prescribed routes and height requirements, preventing oversized vehicles from illegally entering height-restricted areas, avoiding traffic chaos, and ensuring orderly traffic operation.

[0003] However, in actual operation, the inventors found the following problems: Under the existing technology, the height restriction bars are all installed by welding. The welding method results in the height restriction bar being in a single piece. During on-site installation, it is necessary to hoist and install the whole bar. It requires the cooperation of multiple people and machines to install, which has certain limitations. In addition, some drivers of over-height vehicles may misjudge the height of their vehicles and pass through the height restriction bar. When the driver realizes that he has hit the height restriction bar, the vehicle is often already stuck with the height restriction bar, making it difficult to move forward or backward. Forcibly reversing the vehicle can easily damage the height restriction bar and the vehicle. Utility Model Content
