The shaft 28 is mounted on the inner surface of the metal case, the square shaft extends through the matching bearing on the metal case and one end extends out of the metal case. Wherein the two metal case bodies 6 fixedly mounted on the ground are located on a line parallel to the speed bump belt; the end of the flip type support bar 4 located outside the metal case body is connected with the side of the intercepting net; The number of the brake pads 21 is not less than two; the driving piece 22 is composed of two bent sheet-like structures respectively disposed at one end of the rotating shaft, and the driving piece is pressed by the wrench pressing Straightening and pushing the brake pad to squeeze the sprocket; the steel cables pulled out from the two buffering and stopping devices 3 are respectively connected with the two sides of the inverted intercepting net, and the steel cables pulled out from the two buffering and stopping devices are respectively Minute Do not connect with the two sides of the intercepting net; the end of the cable 5 connected to the side of the intercepting net is provided with three connecting heads, and the three connecting heads respectively correspond to the upper, middle and lower positions of the side of the intercepting net Connecting; the distance between the gate 1 and the speed bump matches the width of the road; the length of the speed bump 2 is the same as the length covered by the gate, and the distance between the two buffer brakes is greater than the length of the speed bump .

The technical scheme is characterized in that a speed reducer is arranged behind the gate, and a flip-type intercepting net is arranged in the gap of the speed reducer, and the column of the gate is connected with the pin of the flip-type intercepting net through the rope, when a vehicle collision event occurs, When the vehicle collides with the crossbar of the road gate, the column carrying the crossbar rotates, and the rope wound on the column will pull the pin to contract to release the blocked flip bar, and the flipper with the lower surface in contact with the pin is at the end. The tray and the turntable are flipped around the rotating shaft so that one end located outside the bracket is lifted upward to open the intercepting net between the two flipping levers. During the process of flipping the flip bar, the barrel is in a state of being energized to pull the wire back, and then after the automatic lock is opened, the barrel loses the restraining force, and the wire pulls the end of the flip bar upward to realize the flipping. The pole is raised. The two sides of the intercepting net are connected with a steel cable, and one end of the cable connecting the side of the intercepting net is provided with three connecting heads, and the three connecting heads are respectively connected with the upper, middle and lower three positions of the side of the intercepting net, and the cable is wound On the drum in the buffer car, and one end of the cable is pulled out from the buffer car and connected to the side of the intercepting net, and the brake block is provided with a brake pad that hinders the rotation of the sprocket of the winding cable. When the cable is pulled, the roller rotates accordingly, the wrench on the outer surface of the metal case moves downward, the wrench presses the driving piece, and the driving piece pushes the brake pad to press the sprocket, thereby hindering the rotation of the drum and providing The opposite direction of rotation of the drum, thereby achieving the purpose of hindering the cable from pulling out the cushioning and stopping device. Therefore, when the vehicle hits the intercepting net, the steel cables on both sides of the intercepting net will be pulled, so that the brake pads will continue to provide an obstruction force to the steel rope, thereby gradually reducing the momentum of the automobile and finally achieving the purpose of stopping the car. When the car blocking function is used, the security personnel can remove the wrench. At this time, the driving piece releases the brake pad, and the brake pad does not press the sprocket. The security personnel can use the pipe wrench to rotate the square shaft and then drive the reset gear to rotate, so that the roller Rotating, the cable is re-wound on the drum for the next stop.

In the technical solution, the metal case is buried in the gap between the speed bumps, and the flip lever Turn over to the gap between the speed bumps and block the lock by the pins in the metal case to prevent it from rising upwards. The entire intercepting net falls into the gap of the speed bump between the two flip bars. When the automatic lock is unlocked, the flip lever pops up. Since the top end of the flip lever is connected to the end of the intercepting mesh edge, when the flip lever is lifted up, the entire intercepting net is lifted up and opened to realize the intercepting function.

In the technical solution, the upper, middle and lower portions of the two side edges of the intercepting net are respectively connected to the three connecting ends of the cable connecting ends. The cable is pulled out of the buffer and the cable is subjected to an outward pulling force, and the brake pad gives an opposite blocking force. When the vehicle hits the intercepting net, the vehicle backs up with the intercepting net. At this time, the three connecting ends of one end of the cable are tightened, and the side of the intercepting net is evenly stressed. At this time, the cable is pulled outward from the inside of the buffering and stopping device, and the reverse force of the brake pad is continuously sustained during the pulling process. Therefore, the impact of the vehicle hitting the intercepting net is continuously offset, and finally the vehicle is stopped.

In the technical solution, when the vehicle hits the intercepting net, the flipping bar will be bent or broken, and the impact force of the vehicle will be borne by the intercepting net to realize the organic combination of the flexible anti-vehicle and the steel intercepting, through the steel interception and The flexible car is converted to maximize the resistance to the car, and it also effectively avoids the secondary disintegration of the vehicle after being intercepted, effectively avoiding secondary damage to surrounding personnel.

In the technical solution, the flip type intercepting net is located in the gap of the speed reducer, and the length of the speed reducer matches the width of the road, generally 3-9 meters. If more than 9 meters, a flip support bar can be added in the middle as the intermediate support, the speed reducer The maximum height is 55mm. When the vehicle hits the gate and rushes to the speed bump, due to the guiding action of the speed bump, the impact direction of the vehicle will tilt upwards, just hitting into the intercepting net. At this time, the turning rod will be bent and broken. Or disconnected from the intercepting net, the impact force of the entire vehicle is taken up by the steel cables on both sides of the intercepting net, and gradually offset under the reverse force of the brake pads, the entire intercepting process is smooth, and the vehicle does not undergo secondary disintegration. It can also effectively avoid injuries caused by factors such as rollover.

In the technical solution, the distance between the two buffering and stopping devices is generally selected to be 6000 mm, and the distance between the two buffering and stopping belts is not sufficient, so that the steel cable in the buffering and stopping device has sufficient stretching. Buffer length.
