The working principle is as follows: when the barrier net 3 is impacted by a vehicle and stretched, the barrier net 3 can drag and pull two T-shaped sliding parts 303 in the cable loop 301, the two T-shaped sliding parts 303 are driven to compress springs on two cross-brace short shafts 302 to slide oppositely to directly buffer inertial impact force for the first time, when the barrier net 3 is impacted by the vehicle, two sliding parts 7 can be dragged and pull four springs compressed on the sliding parts to slide backwards along two vertical brace supporting rods 101 to buffer the impact force for the second time, two sliding blocks 201, two connecting rods 701 and two sliding parts 7 are connected together to form a two-crank-slider mechanism, and through the two-crank-slider mechanism, when the two sliding parts 7 are impacted by the barrier net 3 and slide backwards, the two sliding blocks 201 can be driven to compress the springs on two vertical brace short braces 105 to buffer the inertial force for the third time;

the two L-shaped positioning parts 702 are welded on the two sliding parts 7, when the blocking net 3 slides after being impacted, the two sliding parts 7 can instantaneously drive the two L-shaped positioning parts 702 to slide backwards and loosen the two rotating wheels 501, when the blocking net 3 is impacted, the protective frame 5 can be impacted and toppled through the foam buffer cotton 4, the inclined support is kept on the cross-brace ejector rod 102, the obliquely supported protective frame 5 can shield the construction tunnel, the vehicle which breaks the blocking net 3 is upwarped and obliquely guided, the vehicle is prevented from directly rushing into the construction tunnel, the two sliding blocks 201 can drive the two driving parts 2 to slide downwards together when being impacted and driven to slide downwards, the two driving parts 2 can slide downwards and can be meshed to drive the blocking frame 6 to turn over and be placed in a horizontal state, the blocking frame 6 in the horizontal state can be in blocking contact with the roof of the vehicle, and the vehicle is prevented from rolling upwards when impacting the blocking net 3;

the two L-shaped insertion rods 104 can perform inserting positioning on the two driving pieces 2 which slide downwards in the collision, so that the two sliding pieces 7 and the two vertical supporting shaft rods 105 are prevented from being reset by springs to rebound and eject the collision vehicle to cause secondary collision, and in addition, the two L-shaped insertion rods 104 can enable the barrier frame 6 to be kept in a horizontal resisting use state through inserting positioning of the two driving pieces 2.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
