Anti-terrorist road block

Abstract

The invention discloses an anti-terrorist road block. The anti-terrorist road block comprises a supporting frame buried underground. A first lifting mechanism and a second lifting mechanism are arranged in the supporting frame. A cover plate flush with the road surface is arranged at the top of the supporting frame and is hollow. Channels I for lifting the first lifting mechanism are reserved in the cover plate. The second lifting mechanism is arranged in a lifting box of the first lifting mechanism. A barrier net is arranged on a lifting shaft of the second lifting mechanism. Channels II for lifting the barrier net are reserved in the surface of the lifting box. According to the anti-terrorist road block, the simple protecting form in the prior art is changed, double guarantees are achieved by arranging the first lifting mechanism and the second lifting mechanism, protecting abilities of important departments such as important military places, oil depots, ammunition depots and frontier inspection stations are effectively improved, and effective guarantees are provided for safety protection of the important departments and life safety of guard soldiers.

Description

technical field [0001] The invention relates to a road barrier for preventing vehicles from passing illegally. Background technique [0002] Border defense is an important barrier to defending the territorial integrity and security of a country. It plays an irreplaceable role in safeguarding the security of border areas and maintaining the country's continuous stability. Therefore, maintaining the security of border defense is particularly important. Some early border checkpoints used simple roadblock equipment such as traditional electric lifting poles or telescopic doors, and the risk of terrorists breaking through and attacking was very high; The heavy-duty anti-collision unit requires 2-4 people to lift it. The labor intensity is quite high, and it cannot completely intercept all the cars. The phenomenon of punching and jamming occurs from time to time, which poses a high risk to the life safety of the guards and the protection of important military sites. Existing anti...

Problems solved by technology

Some early border checkpoints used simple roadblock equipment such as traditional electric lifting poles or telescopic doors, and the risk of terrorists breaking through and attacking was very high; The heavy-duty anti-collision unit requires 2-4 people to lift it, the labor intensity is quite high, and it cannot completely intercept all the cars, and the phenomenon of punching cards occurs from time to time, which poses a high risk to the life safety of the guards and the protection of important military sites

Existing anti-terrorist roadblocks are designed with a lot of roadblocks with punctured tire devices. When terrorists intend to drive illegally and run over the roadblock, the punctured tire device will puncture the tires of the car and force the car to slow down until it stops by deflation. Roadblocks cannot force cars to stop immediately, especially some tires with good performance, even if they are punctured, they will not deflate immediately, and the car can still drive a long distance to complete the clearance, causing casualties of border guards or guard soldiers and invasion of important military sites
