Anti-collision height limiting rod

Abstract

An anti-collision height limiting rod comprises a table top, a height limiting rod, an ultrahigh detection device and a speed reduction brake device. The ultrahigh detection device, an LED display screen and an alarm are arranged at the top end of the height limiting rod, when the ultrahigh detection device detects that a vehicle is ultrahigh, the LED display screen displays ultrahigh reminding subtitles, and the alarm gives out an ultrahigh warning sound to remind a driver to decelerate and brake in time so that collision accidents are avoided; when the ultrahigh vehicle is detected not to brake in time and is about to impact the height limiting rod, a deceleration braking signal is immediately sent to a control device of the deceleration braking device, the control device automatically uses a hook of a braking hook to hook a front axle crossbeam of an automobile chassis, and the automobile drives the hook to move forwards under the action of an inertia force; and a buffer brake performs buffer braking on the hook through the brake pull rope so that the automobile decelerates, buffers and brakes, and physical injury to an automobile driver due to sudden braking is avoided.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to an anti-collision height-limiting pole. Background technique [0002] The height limit pole is a kind of warning pole before entering the bridge or tunnel to prevent cars from crashing into the bridge or tunnel. For example, the Chinese utility model patent No. 2019202269538 discloses a safety height limit pole, including the first Two support rods, the top ends of the first support rod and the second support rod are fixedly connected with fixed piles, and the first support rod and the second support rod are respectively sleeved with first limiters outside the two fixed piles. The height bar and the second height limit bar, the torsion springs are fixedly connected between the two fixed piles and the first height limit bar and the second height limit bar respectively. Compared with the existing device, the height limit bar is divided into It is divided into two ...

AI Technical Summary

Problems solved by technology

[0003] Through the research on the existing height limit poles such as the above example, it is found that none of them have the function of buffer braking. When the car hits the height limit pole, it often causes damage to the car and the driver because it cannot be braked in time, as in the above example As shown, although the height limit pole is easily knocked open, the bridge or tunnel to be protected behind the height limit pole cannot be knocked open. If a rigid barrier is used to force the vehicle to brake, the inertia force at the moment of braking is very large. It can also cause damage to the driver;
