Description

Technical Field

[0001] The utility model relates to the technical field of height-limited gantry frames, in particular to an anti-collision warning device for a traffic height-limited gantry frame. Background Art

[0002] Traffic gantry is a door frame type frame used for road traffic. Its two columns are like coiled dragon columns. It is also used for road traffic, so it is called traffic gantry. Due to the busy road traffic in the city, vehicles with too high height are prone to traffic accidents when driving in the city. Therefore, height limit gantry is set to give vehicles a mandatory height warning limit to ensure the safe operation of urban roads. At present, the existing traffic height limit gantry is usually equipped with warning signs to simply warn drivers, but some drivers do not carefully observe the warning signs due to their visual blind spots at night and fluke mentality, resulting in friction between the vehicle body and the top of the gantry, causing traffic accidents.

[0003] A Chinese patent discloses a traffic height limit gantry anti-collision warning device (authorization announcement number CN 216809686 U). This patented technology can provide multiple warnings through sound, image and warning lights when an over-limit vehicle is found, thereby improving the warning function. However, when warning for roads of different widths, the width of the device cannot be adjusted and cannot be applied to warnings for roads of different widths. At the same time, the display screen is too high, which is inconvenient for drivers to watch. Therefore, the utility model provides a traffic height limit gantry anti-collision warning device to solve the problems raised in the above background technology. Utility Model Content
