Height-limiting door cross beam for highway

Abstract

The invention relates to traffic safety equipment, in particular to a height-limiting door cross beam for a highway. The height-limiting door cross beam is specially used for being mounted on the urban entry highway around a city and comprises a cable-stayed cross beam and a suspension-type cross beam. A reflective sticker and a height-limiting signboard are arranged on the height-limiting door cross beam. The height-limiting door cross beam is characterized in that the height-limiting cross beam is made of a cylindrical rubber inflatable airbag, and the reflective warning sticker and the height-limiting signboard are pasted on the outer surface of the rubber inflatable airbag. According to the height-limiting door cross beam for the highway, the technical bias that the firmer the height-limiting door cross beam is, the better the effect is is overcome, and the cylindrical rubber inflatable airbag which is abandoned by people due to the technical bias is adopted as the material of theheight-limiting door cross beam.

Description

technical field [0001] The invention relates to traffic safety equipment, in particular to a beam for a highway height-limiting door. Background technique [0002] The highway height limit gate is a device installed on the highway to limit the passage of vehicles exceeding the specified height. It is shaped like a "gate" and its function is a height limit warning. At present, the highway height-limiting gates used on the roads around the city are generally equipped with a steel beam on the hydraulic telescopic vertical rods on both sides of the road. This kind of highway height-limiting gate, because its beam is a steel component, is heavy. , high strength, after a super-high vehicle hits, it is usually a car crash or a car crash or injury; what's more, it will crash the height limit gate, endangering the lives of other vehicles and personnel, hindering traffic and affecting other vehicles It is difficult to pass through normally, and the repair is difficult, the repair tim...

At present, the highway height-limiting gates used on the roads around the city are generally equipped with a steel beam on the hydraulic telescopic vertical rods on both sides of the road. This kind of highway height-limiting gate, because its beam is a steel component, is heavy. , high strength, after a super-high vehicle hits, it is usually a car crash or a car crash or injury; what's more, it will crash the height limit gate, endangering the lives of other vehicles and personnel, hindering traffic and affecting other vehicles Pass through normally, and the repair is difficult, the repair time is long, and the repair cost is high; when the fire truck or special vehicle exceeding the limited height needs to pass urgently, it cannot pass by force, and must wait for the beam of the height-limited door to be raised before passing through
