Highway height limiting door

Abstract

The invention relates to traffic safety equipment, in particular to a highway height limiting door. The highway height limiting door is specifically used for being installed on a highway which is positioned around a city and leads to the city. The height limiting door includes vertical rods and a traffic monitoring camera device, wherein the vertical rods capable of extending and retracting vertically are installed on the two sides of the highway; a height limiting cross girder is fixed to the vertical rods which can extend and retract vertically and are arranged on both sides of the highway,and a reflective sticker and a height limiting signboard are arranged on the height limiting cross girder. The highway height limiting door is characterized in that the height limiting cross girder ismade of a PVC plastic circular pipe, and the reflective warning sticker and the height limiting signboard are pasted to the outer side of the PVC plastic circular pipe. The highway height limiting door overcomes the technical prejudice that cross girders of height limiting doors should be firm as much as possible, and the PVC plastic circular pipe which is abandoned due to the technical prejudiceand pasted by the reflective warning sticker is adopted as a cross girder material of the height limiting door.

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, ...
