Highway height-limiting door

Abstract

The invention relates to traffic safety equipment, in particular to a highway height-limiting door which is specially used for being installed on a city-entering highway around the city. The highway height-limiting door comprises upper and lower telescopic vertical rods installed at two sides of the highway and traffic monitoring camera equipment, wherein a height-limiting beam is fixed on the upper and lower telescopic vertical rods at the two sides of the highway, and is provided with a reflective warning sticker and a height-limiting signboard; the highway height-limiting door is characterized in that the height-limiting beam is made of PVC plastic circular tube which is externally pasted with a reflective warning sticker and a height-limiting signboard; and the highway height-limitingdoor overcomes the technical bias that "the stronger the height-limiting door beam, the better", and adopts the PVC plastic circular tube which is externally pasted with the reflective warning stickerand is abandoned by people due to the technical bias as the height-limiting door beam material.

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
