Description

Semi-rigid anti-collision guardrail

Technical Field

The utility model belongs to the technical field of traffic safety devices, and particularly relates to a semi-rigid anti-collision guardrail.

Background

The highway bridge is provided with the anti-collision guardrail for preventing vehicles from rushing down a cliff, and the traditional anti-collision guardrails are mostly concrete wall guardrails, cable guardrails and waveform guardrails, however, the existing reinforced concrete anti-collision guardrails and the existing waveform anti-collision guardrails cannot well absorb collision energy and easily cause secondary damage to drivers; cable crash barriers, while capable of absorbing some of the crash energy, have limited ability to absorb crash energy.

Therefore, there is a need for a crash barrier that effectively absorbs energy from an impact collision.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide an anti-collision guardrail capable of effectively absorbing collision energy.

The purpose of the utility model is realized as follows: the utility model provides a semi-rigid anticollision barrier, includes a plurality of support columns, is provided with a plurality of anticollision layers that distribute from top to bottom between the adjacent support column, anticollision layer be provided with a plurality of cross structure that connect gradually, cross structure is provided with 2 criss-cross connecting rods, the center department riveting connection of 2 connecting rods, two adjacent cross structure's connecting rod tip riveting connection forms the rhombus district between two adjacent cross structure, be provided with buffer spring in the rhombus district, the line direction between the buffer spring direction perpendicular to support column, two angles in the rhombus district are connected at the buffer spring both ends.

Further, the 2 connecting rods of the cross structure are perpendicular to each other.

Further, the number of the anti-collision layers is 2-7.

Further, the connecting rods are riveted through pins.

Further, a base is arranged at the bottom of the support column.

Furthermore, the side surface of the supporting column is provided with a connecting piece, and the connecting rod is fixedly connected with the connecting piece.

Compared with the prior art, the utility model has the outstanding and beneficial technical effects that: the shock-resistant part of the utility model adopts a combination of a plurality of rhombus structures, the middle of the rhombus area is provided with a spring, the upright post adopts a steel structure, each connecting part adopts a pin for connection, in the process of bearing the shock, the rhombus deforms along the shock direction, and the spring is compressed, so that the collision energy is converted into the elastic potential energy of the spring, the whole process is slower, and the damage caused by the shock is reduced.
