Description

Height and width limiting device for road

Technical Field

The utility model relates to a limit for height width device technical field, concretely relates to limit for height width device for highway.

Background

At present, with the gradual completion of village highway engineering, the pavement of a rural highway is gradually hardened, but due to the passing of ultra-wide and ultra-high vehicles, the pavement of the highway is greatly damaged, and the severe damage of the pavement of the rural highway is caused. In the face of such a severe form, some measures must be taken to limit the passing of ultra-high and ultra-wide vehicles, and the prior art has two measures, namely, width limiting road piers are installed on two sides of a road surface, and the method has the advantages of low cost and convenience in manufacturing, but does not have the function of height limiting and cannot adjust the width limiting; secondly, the height and width limiting frame is arranged on the road surface, and the traditional height and width limiting frame is rigid in structure, so that the passing of ultra-wide and ultra-high vehicles is limited, the passing of large-scale vehicles for rescue, fire fighting and police is also limited, and although the protection effect is achieved on the road, huge potential safety hazards exist.

In order to solve the problems, the adjustable height and width limiting device appears in the market in nearly two years, and the width and the height can be adjusted according to actual requirements after the fixing frame is arranged on a road surface. However, in the actual use process, the adjustable height and width limiting device is manually adjusted, so that the height and width of the medical police firefighter can be adjusted, and the driver of the ultra-high and ultra-wide vehicle needing to pass can also adjust the height and width to lose the functions of height and width limitation. Meanwhile, when the width and the height are regulated, the regulation of the width and the height are not synchronous, and long time is wasted, which is extremely unfavorable for rescue.

An ambulance generally has 3 ~ 4 people, a fire engine generally has 4 ~ 6 people, a large-scale police car has more than 5 police officers.
