Telescopic device of highway bridge guardrail
The invention belongs to the field of road protection, and relates to a telescopic device of a highway bridge guardrail, which comprises a guardrail and a first buffer body arranged on the inner sideof the guardrail; wherein first buffer body is a box body; the number of the first buffer bodies is at least one; elastic pieces which are fixedly connected between the first buffer body and the guardrail, the number of the elastic pieces is at least two, and the elastic pieces are evenly distributed between the first buffer body and the guardrail; a rubber roller which is vertically arranged between the first buffer body and the guardrail; and the rubber roller abuts against the first buffer body and the guardrail. The number of the rubber rollers is at least one; and the rubber rollers are uniformly distributed between the first buffer body and the guardrail. By means of the characteristics of the first buffer block, the rubber roller and the elastic piece, the first buffer body moves through the rubber roller to change the impact angle of an automobile when the automobile collides, the elastic piece is used for limiting the displacement of the first buffer body and the automobile, impact of the automobile on the guardrail is reduced, and secondary accidents caused when the automobile rushes out of the guardrail are prevented.
本发明一种公路桥梁护栏的伸缩装置，属于道路防护领域，包括护栏，设置在护栏内侧的第一缓冲体；第一缓冲体为箱体；第一缓冲体数量至少为一个；弹性件，固定连接在第一缓冲体和护栏之间，弹性件数量至少为两个，弹性件均匀分布在第一缓冲体和护栏之间；胶辊，竖直设置在第一缓冲体和护栏之间；胶辊分别与第一缓冲体和护栏抵接；胶辊数量至少为一个；胶辊均匀分布在第一缓冲体和护栏之间。本发明利用第一缓冲块、胶辊和弹性件的特性，在汽车碰撞时通过胶辊使第一缓冲体发生位移改变汽车的冲击角度，弹性件用于限制第一缓冲体和汽车的位移，减少汽车对护栏的冲击，防止汽车冲出护栏发生二次事故。
