[0002] Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, bridge tunnels, etc. Among them, bridge tunnels have certain height restrictions, and vehicles that exceed the height are very likely to be in danger when passing through bridge tunnels. In order to limit the height of vehicles, a height limit test device is usually set at the entrance of the bridge tunnel for warning. The traditional anti-collision height limit pole at the entrance of the tunnel is generally fixed at a fixed height through a support frame to limit the height of passing vehicles. However, if an illegal vehicle forcibly passes through the height limit cross bar, a collision accident will occur. The height limit cross bar is prone to fall off after being hit. If a staff member passes by at this time, a safety accident is likely to occur, posing a safety hazard.
