Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge height limits, in particular to a height limit metering device for a protective structure under a bridge. Background Art

[0002] Height limit of road and bridge is one of the commonly used traffic restriction methods, which is usually controlled by height limit frame. Traditional height limit frame generally has a fixed structure, and uses two columns and a height limit pole to form a gantry frame structure. The columns are buried underground or fixed on the ground to achieve vehicle height limit. However, traditional height limit frame is prone to accidents when in use. When the driver does not notice the height limit frame or misjudges the height of the height limit pole or vehicle, the height limit frame is a rigid structure, which can easily lead to the collapse and tilt of the columns and the height limit pole, which can easily cause more serious accidents. For this reason, we propose a height limit metering device for underbridge protective structures. Utility Model Content

When the limit rod 7 moves out of the limit groove, people can adjust the height of the limit rod 7. When it is adjusted to the required position, flip the bolt 5 to make the moving block 6 drive the limit rod 7 to move into other limit grooves. When the vehicle collides with the height limit rod, the height limit rod drives the slider 10 to slide, and the slider 10 against the pressure sensor 11 moves, which will compress the spring 14. In this way, within a certain range, the vehicle will not damage the height limit rod, and when the pressure sensor 11 is no longer under pressure, the controller 12 will control the alarm light 18 to sound an alarm, and will remotely notify people, so that people can check and view immediately, thereby improving safety and practicality.
