AI Technical Summary

Technical Problem

The movable guardrail at the opening of the existing highway central partition guardrail is difficult to balance the easy-to-activate mobile function and anti-collision capability, and it is also difficult to facilitate maintenance, replacement and addition.

Method used

A guardrail device including a frame structure, a movable first and second structure, a elastic member and a caster member is designed. By setting up the first and second structures with adjustable weights and connecting them with the elastic components, the state of the guardrail device can be switched by increasing and decreasing weight, thereby achieving a balance between easy opening movement and anti-collision functions, while facilitating maintenance and replacement.

Benefits of technology

The guardrail device is achieved in a balance between easy-to-activate movement function and anti-collision capability, which is easy to repair, replace, add, reduce and change positions, and improves the flexibility and reliability of the guardrail.

Abstract

The invention discloses a guardrail device and a using method. The guardrail device comprises a frame structure. The first structure and the second structure are movably arranged on the frame structure; the first trundle part is arranged at the bottom of the first structure; the supporting component is arranged at the bottom of the second structure; the first elastic component acts on the first structure, and the second elastic component acts on the second structure; when the weight of the first structure is greater than a first preset weight, the first structure overcomes the elastic force of the first elastic component and moves in the direction close to the bottom of the frame structure, so that the first trundle component extends out of the bottom of the frame structure; when the weight is larger than a second preset weight, the second structure overcomes the elastic force of the second elastic component and moves in the direction close to the bottom of the frame structure, so that the supporting component extends out of the bottom of the frame structure. The foundation protection function is guaranteed through the frame structure, the state of the guardrail device is switched by increasing and decreasing the weight, the guardrail device is convenient to move while normal use is not affected, and therefore balance can be achieved between the easy-to-open moving function and the prominent anti-collision capacity.
