The working process of the invention is as follows:
when an ultrahigh vehicle such as a double-layer bus passes through, the double-layer bus impacts the flexible cross beam 3 in a mode of being perpendicular to the height limiting device, and the horizontal height of the flexible cross beam 3 is the set height limiting height, so that the height limiting effect is achieved.

In the impact process, at the moment, the weak point of the flexible cross beam formed by the flexible connecting flange 302 and the bolt in the middle of the flexible cross beam 3 is firstly broken, and is driven by the rotating piece 8 and the pin shaft 9 to rotate around the buffer support 7, the upper upright post 2 and the lower upright post 1 along the forward driving direction until the steering locking device 10 is triggered, the locking piece 1002 is abutted to the locking fixture block 1004 to lock the flexible cross beam section 301, so that the flexible cross beam 3 is prevented from being broken and damaged secondarily.
Meanwhile, the rubber block 308 made of high energy consumption material sleeved on the flexible beam 3 is in compression deformation when being impacted and is matched with the connecting rotating piece 8 to drive the large displacement of the flexible beam section 301, so that double measures are formed, the impact time is prolonged, the impact force is reduced, the serious consequence caused by the roof cutting of the double-layer bus is avoided, the brake response time is given to a driver, and the safety of passengers of the double-layer bus is ensured.
When a muck truck or a large truck passes through, the truck firstly collides with the height limiting device, the weak point of the flexible cross beam consisting of the flexible connecting flange 302 and the bolt in the middle of the flexible cross beam 3 is firstly broken, so that the flexible cross beam 3 rotates in the direction of forward driving after being collided and passes through the rigid cross beam 11, and because the stress of the cross beam is mainly tensile and shear resistant, the stress of the cross beam during collision can be simplified into 90-degree upward impact force and 45-degree upward impact force, so that the ultra-high truck close to the height limiting device can conveniently pass through, and the ultra-high truck and the height limiting device are prevented from being damaged; if the height limiting device is damaged by collision, the steering locking device 10 is finally triggered to lock the flexible beam section 301, the road passing use is not influenced, and the traffic jam is avoided.
When a severely-ultrahigh vehicle passes through, the rigid cross beam 11 on the upper layer is continuously impacted after the flexible cross beam 3 is impacted by 90 degrees horizontally, the rigid cross beam 11 is of a rigid structure, the severely-ultrahigh vehicle can be limited to pass after the flexible cross beam 3 delays the vehicle speed, and the safety of structures such as bridges or tunnels is ensured.
