Road guardrail
The invention belongs to the technical field of guardrails and particularly relates to a road guardrail. The road guardrail comprises a plurality of guardrail units, and every two adjacent guardrail units in a plurality of guardrail units are fixedly connected through a bolt. For the guardrail designed by the invention, when a person climbs over the guardrail, the guardrail is opened, the climbedguardrail is stressed to swing, when the swing amplitude is large, the guardrail cannot be reset by self depending on the gravity center and dragging of the peripheral guardrail, the swing amplitude of a trigger arc block can enable a limiting mechanism to unlock the downward movement of a trigger rack, the trigger rack moves downwards under the action of a first reset spring, the trigger rack moves downwards to pull the corresponding trigger block through a gear, a winding wheel and a first pull rope to release limiting of a corresponding first half support lug and a corresponding second halfsupport lug, and after the guardrail is subjected to pull force in the guardrail mounting direction, the first half support lug and the second half support lug can be disengaged. The road guardrail is advantaged in that the guardrails are disconnected from one another, so the situation that after one of the guardrails topples over, other surrounding guardrails are driven to topple over, and the traffic environment is seriously affected is prevented.
本发明属于护栏技术领域，尤其涉及一种道路护栏，它包括多个护栏单元，其中多个护栏单元中相邻的两个护栏单元之间通过螺栓固定连接；本发明设计的护栏，当有人翻越护栏的时候，被翻越的护栏会受力摆动，当摆动幅度较大即护栏不能够自行依靠重心和周边护栏的拖拽复位时，触发弧块摆动幅度能够使限位机构解锁触发齿条的下移，触发齿条在第一复位弹簧的作用下下移，触发齿条下移通过齿轮、缠绕轮和第一拉绳拉动对应的触发块解除对对应的第一半支耳和第二半支耳的限位，在护栏受到给护栏安装方向的拉力后，第一半支耳和第二半支耳就会脱开；护栏和护栏之间断开；防止当其中一个护栏倾倒后，周围的其它护栏就会被带动倾倒，严重影响交通环境。
