Foam plastic road height-limiting door beam

Abstract

The invention relates to traffic safety equipment, in particular to a foam plastic road height-limiting door beam, which is specially for being installed on a height-limiting door on an urban descending road around a city, and is installed horizontally on the vertical rods which can stretch and are arranged on both sides of the road. Cable type installation or suspension type installation can be provided. The beam is provided with a reflecting and warning sticker and a high-limiting signboard, and is characterized in that the material of the high-limiting cross beam is plastic foam which has arectangular cross section and is adhered with a nylon cloth cylinder; the reflecting and warning sticker and the high-limiting signboard are adhered on the nylon cloth cylinder, the road height-limiting door overcomes the technical prejudice that 'the stronger the beam of a height-limiting door is, the better the height-limiting door is', the rectangular foam plastic which is adhered with the nylon cloth cylinder, which is discarded by people due to the technical prejudice, is used as the material of the beam of the high-limiting door.

Description

technical field [0001] The invention relates to traffic safety equipment, in particular to a foam plastic highway height-limiting door beam. Background technique [0002] The highway height limit gate is a device installed on the highway to restrict the passage of vehicles exceeding the specified height. At present, the highway height limit gates used on the roads around the city and entering the city are generally a steel beam on the hydraulic telescopic vertical poles on both sides of the highway. This kind of highway height limit gate, because its beam is a steel member, is heavy. , high strength, after the collision of the super-high vehicle, the car is generally killed or injured by the car; what is more, it will crash the high-limit door, endanger the life safety of other vehicles and personnel, and obstruct traffic and affect other vehicles. Normal passage is difficult to repair, the repair time is long, and the repair cost is high; when the fire truck or special veh...

Problems solved by technology

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
