Electromagnetic damping danger avoiding lane with gradually-changed magnetic conductive interval

ZHANG BENNIU / SANG XIAOYU / LIU YANG

The invention relates to an electromagnetic damping danger avoiding lane with a gradually-changed magnetic conductive interval, and belongs to the technical field of highway construction design and construction. The danger avoiding lane comprises a net cable structure, an electromagnetic damping structure and a fixing device, wherein the electromagnetic damping structure comprises a sliding rail and guardrails; the guardrails are arranged on the left and right sides of the danger avoiding lane; the electromagnetic damping structure is mounted on the guardrails; the net cable structure is arranged between the guardrails on the two sides; the fixing device is in an inverted U shape, and the two ends of the fixing device are engaged together through the sliding rail; the sliding rail is obliquely arranged in the length direction of the danger avoiding lane, and the sliding rail enables pulleys to directionally slide. According to the resistance device, traditional resistance is utilized,electromagnetic damping is increased, and thus the length of the danger avoiding lane is reduced. The electromagnetic damping structure adopted by the invention can output a relatively average dampingacting force to the outside, so that damage to vehicles and members caused by sharp increase of the damping force is prevented.

本发明涉及一种导磁间距渐变式电磁阻尼避险车道，属于公路建设设计与施工技术领域。该避险车道包括网索结构、电磁阻尼结构和固定装置；所述电磁阻尼结构包括滑轨和护栏；护栏设置在避险车道左右两侧；电磁阻尼结构安装在护栏上；网索结构设置在两侧护栏中间；固定装置呈倒U型，其两端通过滑轨咬合在一起；滑轨在避险车道长度方向上倾斜布置，导轨使得滑轮能够定向的滑动。本发明的阻力装置不仅利用了传统的阻力，而且增加了电磁阻尼，从而减少避险车道的长度。本发明采用的电磁阻尼结构可对外输出较为平均的阻尼作用力，防止阻尼力的激增对车辆及成员造成伤害。
