Highway height limiting device

Abstract

The invention discloses a highway height limiting device. The device comprises two stand columns arranged on the ground and a height limiting component arranged between the two stand columns, wherein a round connecting hole is formed in each stand column, the height limiting component comprises a first cross bar, round connecting ends located in the round connecting holes are arranged at the two ends of the first cross bar, and damping components for resisting the rotation of the corresponding round connecting end are arranged on the wall of each round connecting hole. By the adoption of the highway height limiting device, buffering can be achieved when a vehicle collides with the device, impact strength can be reduced, casualties and vehicle damage can be avoided, or the number of casualties and vehicle damage degree can be reduced, and damage degree can be reduced after the height limiting device is impacted so that maintaining time can be shortened and maintaining cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a road height limiting device. Background technique [0002] In order to avoid damage to construction facilities such as roads and bridges caused by super-high vehicles passing through, many roads are equipped with limited height devices. [0003] Most of the currently widely used height limiting devices for vehicles are welded and fixed by steel frame structures. When the vehicle comes into contact with the height limiting device, it is a rigid collision, and the impact force is huge, which is likely to cause serious casualties and vehicle damage. The high device was seriously damaged after being hit, and the maintenance time of the height limiting device was long and the cost was high, which directly affected the normal traffic of the road. Contents of the invention [0004] In order to solve the above problems, the present invention provides a highway height limi...
