[0002] Highway majors are worth engaging in road engineering design, construction, management and related research. During highway construction, it is necessary to install corresponding anti-collision guardrails in the middle or on the side of the highway. Anti-collision guardrails can reduce vehicle speed when vehicles collide, effectively protecting the lives of drivers and passengers and reducing losses caused by traffic accidents. Anti-collision guardrails are usually made of metal, concrete or plastic and have certain elasticity and impact resistance.

[0003] At present, when using the anti-collision guardrail on the market, generally, the corrugated guardrail plate is installed between the support column and the anti-collision guardrail is supported by assembling the support column and the ground. The contact area between the existing anti-collision guardrail and the ground is small, and it is easy to deform and displace when impacted, and the safety is not high. Therefore, we propose a high-safety anti-collision guardrail. Utility Model Content

[0023] A connecting plate 6 is provided inside the support column 1, and a movable groove 7 is provided on the surface of the support column 1, a mounting seat 8 is provided on the outside of the support column 1, and a mounting cavity 9 is provided inside the mounting seat 8; the mounting cavity 9 corresponds to the position of the movable groove 7, and guide grooves 10 are provided on both sides of the mounting seat 8 near the mounting cavity 9, and a connecting seat 11 is provided below the support column 1 near the connecting plate 6, and the outer end of the connecting seat 11 passes through the movable groove 7 and the mounting cavity 9 in sequence; the bottom of the connecting seat 11 is connected to a plug rod 12, and the edge of the connecting seat 11 is connected to a guide block 13 The guide block 13 is docked inside the guide groove 10, and a threaded rod 14 passes through the middle of the connecting seat 11; the threaded rod 14 is docked between the support column 1 and the connecting plate 6 through the bearing seat, and the upper end of the threaded rod 14 passes through the connecting plate 6 and is installed with a bevel gear set 15. A hexagonal block 16 connected to the bevel gear set 15 is provided on the outer side of the support column 1. The threaded rod 14 and the connecting seat 11 are threadedly connected, the cross-sectional size of the guide block 13 matches the cross-sectional size of the guide groove 10, and the guide block 13 and the guide groove 10 are slidingly connected.

[0024] During the specific implementation, after the bottom of the support column 1 is installed on the ground, a matching wrench is set on the outside of the hexagonal block 16 and rotated. The rotating hexagonal block 16 drives the connected bevel gear set 15 to rotate synchronously, and the threaded rod 14 rotates with the rotation of the bevel gear set 15. Since the threaded rod 14 and the connecting seat 11 are threadedly connected, the outer connecting seat 11 can drive the connected plug rod 12 to move downward synchronously with the rotation of the threaded rod 14.

After loosening, the limit seat 21 and the connecting pin 19 can automatically reset inward by the elastic force of the spring 20 until the limit seat 21 passes through the fixed seat 17 and is plugged into the reserved groove on the surface of the spliced ​​corrugated guardrail plate 3, so as to assist in limiting the two corrugated guardrail plates 3 to be spliced. Finally, the matching fastening pins are used to successively penetrate the overlapping mounting holes 4 between the two corrugated guardrail plates 3 to lock and splice them. Through the mutual cooperation between the fixed seat 17 and the telescopic limit seat 21, the two corrugated guardrail plates 3 to be spliced ​​can be assisted in limiting the position, thereby facilitating the limited splicing of the anti-collision guardrail.
