Highway height-limiting door

Abstract

The invention relates to traffic safety equipment, in particular to a highway height-limiting door. The door is a special height-limiting door installed on a surrounding highway leading to a city. Thedoor comprises vertical telescopic rods and traffic monitoring and shooting equipment, wherein the vertical telescopic rods are installed on the two sides of the highway. A height-limiting cross beamis fixed to the vertical telescopic rods on the two sides of the highway, and has a reflective sticker and a height-limiting signboard. The highway height-limiting door is characterized in that the height-limiting cross beam is made from cylindrical foamed plastics with a nylon cloth cylinder adhering to the exterior of the foamed plastics, and the reflective warning sticker and the height-limiting signboard are attached to the nylon cloth cylinder. The highway height-limiting door overcomes the technical prejudice that the firmer a height-limiting door cross beam is, the better the effect is, and the cylindrical foamed plastics, which are abandoned by people with the technical prejudice, with the nylon cloth cylinder adhering to the exterior are adopted as height-limiting door cross beammaterials.

Description

technical field [0001] The invention relates to traffic safety equipment, in particular to a highway height-limiting gate. 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 time is long, ...

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
