An anti-riot vehicle arresting device

Abstract

The invention provides an antiriot vehicle-stopping device. The antiriot vehicle-stopping device comprises a supporting unit capable of being installed below the ground, a bearing unit capable of rotating around one end of the supporting unit and an anti-collision unit vertically arranged at the bottom of the other end of the bearing unit and used for preventing vehicle collision. The top end of the anti-collision unit is connected with the end of the bearing unit, a driving unit is arranged at the bottom of the bearing unit and can drive the bearing unit to rotate around one end of the supporting unit, and the rotating bearing unit drives the anti-collision unit to ascend vertically. The antiriot vehicle-stopping device is easy to operate, practical and capable of being rapidly started within short time and effectively stopping invasion vehicles.

Description

technical field [0001] The invention relates to a vehicle arrester, in particular to an anti-riot vehicle arrester. Background technique [0002] Anti-riot and anti-terrorism equipment is an important basic equipment for gate guards in various enterprises, institutions, communities, courtyards and other gates to perform anti-riot and anti-terrorism tasks. [0003] The car stopper is divided into two types: blocking type and tire breaking type, and the tire breaking type car stopper is also divided into vertical type and horizontal type. Vertical car arrester, that is, the nail plate is upright in normal state. When using it, let the nail plate turn over and fall down. When not in use, turn the nail plate up manually. It is very troublesome to use, and the vertical car arrester takes up a lot of space on the road. , and its connection structure is also more complex. The horizontal car arrester includes a guard plate for fixed connection with the ground, a rotatable transmis...

AI Technical Summary

Problems solved by technology

The horizontal car stopper is more convenient to use, but the dust is easy to enter through the through hole for the needle to enter and exit. After a long time, it will affect the rotation of the drive shaft and cause malfunctions.

[0004] In the prior art, the gate defense depth of most units is small. If there is a vehicle collision, the reaction time is short, and it is necessary to quickly set up anti-collision barriers in a short time. At the same time, most of the pipelines and equipment are installed under the gate passage. , there are warm trenches, cable pipes and natural gas pipelines underground, and the car-stopping equipment must have fast action and effective car-stopping capabilities, resulting in the diversification of car-stopping equipment, which brings certain difficulties to the rapid response and stability maintenance work.

Most of the existing blocking devices in China are complex in design and have a long response time, generally more than 5 seconds
